JinjingandJinwoo-H	6e25a90085	fix(terminal): keep a quick command queued until its own spawn takes it (#15630) ... * Increase shell readiness timeout to match daemon barrier Slow interactive rc files can take longer than 1.5s to initialize. Raise the startup command readiness timeout from 1.5s to 15s to match the daemon barrier and prevent queued commands from executing mid-startup. * fix(terminal): keep a quick command queued until its own spawn takes it (STA-4876) Triggering a quick command opened a terminal tab titled with the command's label, the shell started and drew its prompt, and the command never ran. TerminalPane snapshots `pendingStartupByTabId[tabId]` in a useState lazy initializer, and a mount effect deleted the entry immediately. The pane's key is `${tab.id}-${tab.generation ?? 0}`, so anything that bumps generation before the command reaches a shell — the stall-recovery remount fired from `requestTerminalPaneRecovery`, or the allDead activation regeneration — mounted a second pane that re-read an emptied slot and spawned with no command at all. The loss was permanent, which is why every scope failed alike: repo, global and agent-prompt all funnel through the same queue-then-snapshot sequence. Spend the entry at `onPtySpawn` instead, which is the one point that proves this pane's own fresh spawn exists. A pane retired mid-connect never reaches it, so the command stays queued for the next mount; reattach skips `onPtySpawn`, so it cannot spend a command it never delivers. Three details are load-bearing: - Ownership is reference identity (`paneOwnsQueuedStartup`). Setup and issue splits borrow the same `deps.startup` field for their own one-shot payload, and that payload can be structurally identical to the queued command, so a truthiness test would let a split pane spend a command it never runs. - The consume runs after `bindActivePanePty`. While the tab still has no ptyId, the queued entry is the only thing holding its worktree out of the retention-budget force-park, so dropping it first unmounts the pane mid-spawn. - The callback is one-shot. `onPtySpawn` fires on every fresh spawn a pane makes, including hibernation wake and the respawn ladder, and a command queued after the first launch belongs to that later launch. Known residual, documented at the call site: the consume tracks "a pty exists", not "the command ran". Windows embeds short commands in the shell argv, so they execute before the spawn resolves and a pane retired in that window re-delivers on remount; on POSIX the write waits for shell-ready, so a pty that dies in that window loses a command already spent. Closing either needs a delivery signal from main rather than this callback. Both windows are narrow, and both are strictly better than losing the command unconditionally. * fix(terminal): guard the queued-startup wiring the review found untested Follow-ups from the final review pass on this branch. - Collapse the ownership + one-shot decision into `createQueuedStartupConsumer` so the call site is a single call rather than inline logic no test could reach. Two mutants survived the whole suite before this: relaxing ownership to a truthiness check, and dropping the one-shot guard. Both now fail. - Rewrite the throwing-consume test. It asserted `updateTabPtyId` had been called, which runs *before* the callback, so it passed with the try/catch deleted. It now asserts the throw does not escape into the connect promise, which is the invariant the try/catch actually provides. - Correct the `onQueuedStartupSpawned` docblock. It claimed the callback is "the first moment the command is guaranteed to reach a shell"; the diff's own caveat says otherwise, since Windows runs an argv-embedded command before this fires and a POSIX shell can die before the shell-ready write. It marks a live shell, not delivery. No behavior change: the consumer is the same predicate and the same one-shot, moved behind one exported seam. * fix(terminal): roll shell wrapper isolation into a fresh daemon * Revert "Increase shell readiness timeout to match daemon barrier" This reverts commit 6ab273ef36. * Condense queued startup spawn comment Simplify the multi-paragraph explanation into a concise summary that captures the key points: spawn must wait until after the pane is bound to preserve the worktree from force-parking, and the behavior differs between POSIX and Windows for delivery timing. * fix(terminal): prevent consuming replaced queued startup commands When a queued startup is replaced before the pane's first spawn, the one-shot guard alone still allows consuming the replacement. Add isStillQueued callback to verify the slot still holds the originally captured command (STA-4876). --------- Co-authored-by: Jinwoo-H <jinwoo0825@gmail.com>	2026-08-20 12:15:08 -07:00
Jinjing	d8e9fa1bb9	Revert "fix(terminal): apply pane padding on all four edges (#15544)" (#15623) ... This reverts commit 4b2ed5ddd4.	2026-08-20 09:57:55 -07:00
Neil	feaebabf2c	test(terminal): pin the two conditions that keep macOS period substitution out (#15393) ... macOS rewrites a double space into ". " and hands the period to the pty. Orca is not immune to that: a plain Chromium textarea in the Electron version pinned here does substitute, measured on hardware with real key events, and spellcheck="false" does not prevent it. What prevents it is that the forwarder claims a plain space keydown and then empties the helper textarea, so the text system never sees the word preceding the space. Neither half was a decision. Before 01bcc8dca2 the claim predicate excluded space, letters and digits, the field accumulated, and the substitution fired on real hardware. That commit widened the predicate for unrelated reasons - IME commit survival and kitty encoding - and suppressed this as a side effect it never mentions. The predicate already declines on modifiers and during composition, so a later narrowing would return the bug with nothing to catch it. This does not test the substitution, which a unit environment cannot produce. It tests the two conditions measured to suppress it. Verified non-vacuous: narrowing the predicate back toward punctuation fails three of the four, and removing the blanking fails the fourth. Refs #11504	2026-08-20 03:08:29 -07:00
NeilandBrennan	c92f394cde	fix(pty): delete the reply-withholding scheduler (#15578) ... * fix(pty): answer a terminal colour query in its own turn Root-cause follow-up to #15559, which stopped a CPR overtaking a deferred colour reply but left the deferral itself in place. Orca answers terminal queries by writing to the PTY master, which a line discipline in ECHO copies straight back out as junk on a cooked prompt (#12112). The guard was to withhold the write until an `stty` subprocess proved ECHO clear — and forking is what forced the decision to be async. Any deferral, however short, lets a reply written later in the same turn overtake this one, so the async probe was the bug's root cause. Read the bit synchronously instead. Linux and the BSDs redirect a master's mode ioctls to the slave, so a `tcgetattr` on the master fd node-pty already owns answers for the slave with no fork: measured 0.26us against 2403us for the subprocess. With a verdict available inline, a querying program that already cleared ECHO — every raw-mode prober, including the colour probe behind the `gh auth login` report — is answered in its own turn and can never be reordered. The deferral stays for the genuinely cooked case, and the ordering guarantee stays underneath it: hosts whose node-pty predates this patch get no sync probe and fall back to the deferred path, which mixed client/host versions make a live production path. Reply routing is all-or-nothing: a payload needing neither containment nor ordering stays on the host's own path, so a CPR answered during shell startup cannot pass the daemon's post-ready flush gate and splice into the buffered startup command. Native side is fail-safe: a kernel that did not redirect would answer from the master's own termios, whose ECHO defaults set, so the degraded verdict is "echoing" — never a false "quiet". The JS half ships in the pnpm patch while the binding needs a source build, so ORCA_REQUIRE_NODE_PTY_ECHO_STATE=1 makes CI fail rather than silently skip when it is handed an upstream prebuild. Co-authored-by: Brennan <brennanb2025@users.noreply.github.com> * fix(pty): keep the flush ordered under synchronous re-entry Three defects found in external review of the reply-ordering work. node-pty delivers onData inside the master write, so a query can be answered while the queue is mid-flush. `flushPendingWrites` spliced the array off before writing, so that reply saw an empty queue, took the same-turn path, and landed ahead of entries the loop had not written yet — reproduced as 01, 99, 02, 03. It now shifts one entry at a time so a re-entrant reply queues behind the rest, bounded by the length at entry so a re-entrant push cannot spin the loop. An overflow flush can re-enter as far as teardown. `answer` did not re-check `closed` afterwards, so it queued behind a closed delivery, returned true, and the reply was never written and never reported. The payload router's ownership comment overstated its guarantee. The `any` semantics are deliberate — returning false after a constituent was already written would have the caller re-write the whole payload and duplicate it into the child's stdin — so the residual mixed-failure drop is now documented rather than implied away. * fix(pty): delete the reply-withholding scheduler Orca answered a terminal query by withholding the write until a probe proved the slave's ECHO bit was clear. That was the wrong mechanism, and it is now gone: replies are written in the caller's turn and their echo is contained on the output side, where it always was. Withholding never removed an echo. The wait was bounded and always ended in a write, so the output-side projections were doing the work the whole time — including the readline rewrite, which happens with the tty already raw and which therefore no reading of the ECHO bit can predict. What withholding did add was an asynchronous write path, and that is what let one reply overtake another and land in the next program's stdin (#15559), what produced a re-entrancy inversion inside its own flush, and what four rounds of regressions have lived in. The last thing it covered was the verbatim echo of a `stty -echoctl` tty. That shape is now projected directly. It starts with ESC, so it is matched only when complete and never held as a partial: holding it would take a bare trailing ESC from the query parser and an expired hold would release it raw, so a query torn at its own ESC would never be answered. Complete-match-only is what makes the shape safe to project at all. Measured on a real pty: a cooked-mode master write is both echoed AND delivered — ECHO copies the bytes without consuming them from the slave's input queue, so a program arming raw mode with TCSANOW/TCSADRAIN (libuv's setRawMode, hence every Node agent) still reads them. Only a TCSAFLUSH switcher discards it, which it does on every terminal, none of which gates a reply on termios state. Deletes the pending-write queue, the async stty probe, the poll budget and probe rate limit, the deadline-driven flush, and the answer/ answerInOrder split. Replies now leave in call order by construction. No packaging, native or CI surface is touched. * test(pty): restore stty-probe coverage and pin the duplicate-query retry Archaeology on how withholding got here, and what its tests were really protecting. Deleting the ECHO probe took four tests with it that were not about the probe at all: they cover createSttyProbe, which the shell-readiness line-editor probe still uses — in-flight sharing, the per-platform stty flag, and transient-versus-permanent failure latching. Restored against the line-editor probe, which is now their only caller. Also pins the property that answers the one case an immediate write cannot serve. A program that queries while cooked and then arms raw mode with TCSAFLUSH discards the reply with the rest of its input queue. Nothing can prevent that from the terminal side, and no terminal tries. What matters is that such a program re-queries after its own timeout: the ingress declines to answer an already-answered slot but forwards the duplicate downstream, so the renderer's emulator answers the retry, by which point the program is raw. The retry path is the recovery, not withholding. * ci(pty): keep the fish real-PTY test in the shell-contracts lane only Reverting pr.yml to main dropped the exclusion for the fish query-reply test, which this branch keeps, so it would have run in the sharded lane as well. Restores it to the shell-contracts include list and the shard exclude list, and drops the parallelism expectations for the deleted cooked-querier suite and the echo-state env guard. --------- Co-authored-by: Brennan <brennanb2025@users.noreply.github.com>	2026-08-20 02:15:42 -07:00
Brennan Benson	3e079debec	fix(sidebar): host-qualify discovery notice rows on multi-host projects (#15546) ... * fix(sidebar): host-qualify discovery notice rows and collapse one checkout's twins A project checked out on several hosts emits one discovery-notice row per checkout, and those rows only named the project. A sidebar with paired remote hosts therefore showed several identical "N hidden worktrees" buttons under one project header, with no way to tell which machine each belonged to — or that one of them was another machine's worktree inbox entirely. Two causes, both fixed here: - Notice rows carried no host context, unlike worktree rows, which have been host-labelled since STA-4343. Both notice rows now take a host label, applied per project (not per rendered section, since a card can land in the pinned fallback) and only when that project spans hosts. The label also lands in the review, expand, and dismiss accessible names, so the actions that write to a specific host's repo record say which host that is. - One machine registered as a direct SSH target *and* paired as a runtime environment gives a single on-disk checkout two repo records with independent hidden-worktree state, so it emitted two rows for one directory. Repos now resolve to a (hostname, path) checkout key, and twins collapse to the record this client persists itself — its visibility state is the user's own and survives the paired runtime going away. The key is deliberately conservative: an unresolved hostname, or a tunnelled environment answering on loopback, yields no key and never collapses anything. Renderer-only; no wire or persistence change. * fix(sidebar): drop the machine-identity collapse, gate notice labels on host ids Replaces this branch's second change after a plan review found it has no precedent and eight concrete failure modes. Deleted: the (hostname, path) checkout key that collapsed two repo records believed to be one machine. Orca models a direct SSH target and a paired runtime environment as different execution hosts everywhere else; that change asserted sameness by resolving strings a user typed in two places. It also dropped rows (a differing count vanished with the shadowed record), flipped with the sidebar host filter, ignored port and user so a host and a container on it could merge, tie-broke on repo-store order, was disabled in the one case Orca can prove (a tunnelled pairing answers on loopback) and fired only on coincidence, and left the visibility dialog showing state the sidebar had hidden. Its module also carried a literal NUL byte, so git classified the file as binary and the diff was unreviewable. Kept, with two corrections: notice rows still carry a host label, but the gate now counts distinct host ids rather than distinct label strings — two hosts sharing one user-facing label is exactly when the rows are hardest to tell apart — and membership is read from the unfiltered repo universe rather than the host-filtered notice candidates, so a label no longer appears and disappears with the filter. Two hosts that share a label still render the same label. Disambiguating that is a shared concern across worktree badges, host headers, and host-filter options, and needs its own design; three verification passes each found a different hole in doing it here. Follow-ups: general host-label collision, and the repo-record duplication that produces the twin rows in the first place. * fix(i18n): catalog notice host scope copy * feat(sidebar): show each notice row's host with the project-on-host glyph Notice rows on a multi-host project already carried a host label, but two hosts can share one user-facing name, and the label truncates first in a narrow sidebar. Each row now also carries its host's glyph. Deliberately the same indicator worktree cards use (worktree-card-header): a Server glyph, ServerOff when a paired runtime has no live status, and a "Project on ..." tooltip naming the host — SSH and runtime keep their distinct tooltip wording. Local hosts draw nothing, as on the cards. The glyph is shrink-0, so unlike the text label it survives the sidebar narrowing, and the row keeps an identifying mark either way. Rows now carry the host id alongside the label, since the label alone cannot select a glyph or its tooltip. Catalog entries for the new copy ship with the change rather than relying on inline fallbacks. * refactor(sidebar): draw notice-row hosts with the shared host glyph Follow-up to the notice-row host indicator: use the one glyph vocabulary the app already has instead of a second copy of it. HostRowIcon — a monitor for this computer, a server for anything remote — was private to the composer's run-target rows. Moved to a shared home and reused, so the sidebar and the composer cannot drift apart. The run-target module re-exports it, leaving its own call sites untouched. Every notice row now gets a glyph, local included, so no row is the odd one out; the tooltip still names the host and says when a paired runtime has no live status. Same size and tone tokens across kinds, so no row reads as decorated relative to its neighbours. * fix(sidebar): make notice host glyphs accessible	2026-08-20 01:38:28 -07:00

Brennan Benson	2e895da937	fix(browser): name the requesting frame and the permission in denial notices (#15542) ... * fix(browser): name the requesting frame and the permission in denial notices Two defects in the same notice, both found by the review of #15481 and left out of it deliberately. The notice named the wrong site. setPermissionRequestHandler passed webContents.getURL(), which is the top-level document, so a permission request from a cross-origin sub-frame was attributed to the embedder. Every PermissionRequest variant carries requestingUrl, so all three call sites now use it and fall back to the top-level document only when it is absent. The notice also showed raw Chromium permission names. humanizePermission mapped two permissions and returned the raw token for the rest. That now matters more: #15481 granted ordinary storage-access and left top-level-storage-access denied, making it the storage denial a user can still hit - rendered as its raw token. The default still returns the raw token. Inventing prose for a permission nobody has seen is worse than showing its real name. Does not change any permission verdict, and does not fix Google sign-in (#15221). * fix(browser): keep permission denial attribution accurate Capture fallback URLs before asynchronous media permission handling and treat opaque requesters as unknown rather than blaming the top-level page. Clarify permission descriptions and cover origin normalization, navigation races, and mapped copy.	2026-08-20 00:22:59 -07:00

On a pane with no box it paints the freshly cleared render model into nothing, and because the observer only fires on a state change it never re-pauses the service. It also clears _needsFullRefresh, which is the only thing that makes _handleIntersectionChange repaint on reveal and flush the deferred _pausedResizeTask. Latch instead for those panes: terminal.refresh() re-arms _needsFullRefresh and xterm repaints from it on reveal. * test(terminal): type the render-service repaint mock	2026-08-19 23:25:47 -07:00

A pending orca.yaml trust prompt owns the promise that quick create awaits, and eviction dropped its resolver: that submit never settled, and because the trust prompts are serialized on a module-global chain, every later create/remove in the session silently did nothing. Modal data can now carry an onModalDismissed callback that the slot invokes when it evicts an entry; the trust prompt uses it to resolve as 'skip', which is what dismissing the dialog already means. * fix(workspaces): make trust prompt settlement one-shot	2026-08-19 18:12:29 -07:00

Neil	d4460d34f3	fix(terminal): stop a Hangul-terminating digit being eaten as a candidate pick (#15429) ... * fix(terminal): stop a Hangul-terminating digit being eaten as a candidate pick A digit typed immediately after a Hangul syllable is dropped in the terminal on Wayland. Typing 아1 produces 아. The syllable composes and commits correctly; only the keystroke that ends it is lost. Reproduced on Ubuntu 24.04, GNOME Shell 46, ibus-hangul 1.5.5, in a nested Wayland session with real key injection. The pty receives 아 on Wayland and 아1 under X11 on the same machine with the same engine, and a GTK client in the same Wayland session receives 아1 - so the compositor, the input method and the digit are all behaving. The difference is where the digit is delivered. Under X11 ibus-hangul swallows it into the preedit and commits 아1 as composition text. Under Wayland it commits 아 and lets the digit through as an ordinary key - and the jamo before it arrive with no keydown at all, only keyups. That orphaned keyup is what breaks it. A plain letter keyup with no matching keydown arms a 1500ms window in which a bare digit is treated as a candidate selection, because a Pinyin engine indexes its candidate list by digit. The digit lands microseconds later, inside the window, and is suppressed. The window disarms after exactly one digit, which is why the syllable survives and only the terminating key vanishes. A Hangul engine has no numbered candidates over its preedit - a digit ends the syllable and is literal text - so the guard was spending its one suppression on a keystroke meant for the shell. The tracker now records whether the current preedit is Hangul and the guard declines. Read from compositionupdate rather than compositionend: a Pinyin preedit is the Latin spelling being narrowed while its commit is the Han text, so reading the commit would misclassify Pinyin and reopen the bugs the guard was added for. Space is untouched; only digits are reclassified. Verified A/B/A on that machine: unfixed drops the digit, this change preserves it, reverting drops it again, three runs each. The X11 case and both existing ibus-hangul specs still pass. Closes #15299 * fix(terminal): expire the Hangul preedit flag and narrow its digit exemption Review of the #15299 fix found the Hangul classification could not be retired and that it exempted more than the reported bug. The flag was written only on a non-empty compositionupdate and cleared only on blur, so it latched for the whole focus session. Switching input engine (Hangul -> Pinyin) under fcitx/ibus moves no DOM focus, and the #8241 orphan-digit path emits no composition and no input events, so nothing could refresh or clear it. The stale flag then turned the #8241/#7543 Pinyin candidate-digit guard off silently and permanently - the regression those guards exist to prevent. It now expires against lastCompositionEventAt on the same staleness window as the neighbouring guards, and compositionstart clears it because the following compositionupdate re-reads the preedit script. It is deliberately not cleared on compositionend or on input: the bug is a digit arriving after the commit, and both recordings deliver the commit's own insertText before it. Clearing on either reverts the fix - the orphan-window test fails when input clears it. The exemption also gated suppressCandidateKey as a whole, so it fired during a live composition as well. That is broader than the bug, which is exclusively a digit after compositionend, and it is unsafe: the earlier claim that no Hangul engine indexes candidates by digit over a preedit is wrong. ibus-hangul's Hanja conversion (Hanja key / F9) puts a numbered lookup table over a live Hangul preedit, and its symbol table behaves the same. Only the orphan-keyup guard - which arms off a bare keyup and cannot see which engine produced it - now declines. The tests drove a shape neither recording produces: an empty compositionupdate immediately before compositionend, which armed the 250ms post-composition window. The Wayland reproduction has no empty update, and the X11 fixture follows its empty update with deleteContentBackward + insertText, which disarms that window. The suite now follows the recorded trace, asserts the 250ms window never arms, and covers both the expiry and the live-preedit Hanja case. Refs #15299	2026-08-18 23:15:12 -07:00
Brennan Benson	12724068b7	fix(sidebar): render folder workspaces under every Group by mode (#15362) (#15404) ... * fix(sidebar): render folder workspaces under every Group by mode (#15362) Folder-workspace rows were emitted in exactly one place, inside the repo-grouping branch of buildRows, so switching the sidebar to Status, PR status or None dropped them from every lane. Membership is now decided once, above the groupBy switch; a mode only chooses which lane a workspace lands in. Lane assignment is an exhaustive WorktreeGroupBy switch with no default clause, so a future grouping mode is a compile error here rather than a silent regression. Not a regression: the groupBy !== 'repo' gate predates folder workspaces by two weeks (#2866), and #5172 added folder-workspace emission below it, unreachable for non-repo grouping from its first commit. Also fixes four further paths where the same row kind went missing: - Flat mode gated its whole section on worktree count, so an account with only folder workspaces rendered nothing at all. - A collapsed folder-only lane header rendered globally instead of under its host section, because empty worktree lists yield undefined host counts. Host id maps now carry explicit empty arrays so the host fallback cannot leak global worktree ids. - Reveal resolved folder workspaces to project-group header keys only, so revealing one inside a collapsed lane never expanded it. Reveal now reuses the same lane function as grouping, expands the host header, and covers the agent-send path and the host-qualified row lookup. - The Clear Filters empty state ignored folder workspaces, so a folder-only account lost them whenever any filter was active. This one reproduced under Project grouping too. Behaviour deliberately unchanged: archived folder workspaces are still not filtered, matching current behaviour rather than making membership mode-dependent. Pinned folder workspaces still render in their natural lane rather than the Pinned section, now uniformly across modes. * fix(sidebar): count folder workspaces in host badges	2026-08-18 19:24:38 -07:00
Brennan Benson	c228030516	fix(tabs): keep an open diff focused while agents stream (STA-4697) (#15390) ... * refactor(tabs): put the visible-tab-type projection in one place Three copies of toVisibleTabType had drifted: the runtime one omits 'simulator'. Move the canonical projection next to the two unions it maps between and replace the two copies that are already identical to it. The runtime copy is left alone on purpose - unifying it would change behavior, so it goes with the follow-up. * fix(tabs): keep an open diff focused while agents stream (STA-4697) resolveWebSessionVisibleTabId answered 'which tab is the user looking at' by inverting a many-to-one projection: it compared tab.contentType against the coarse activeTabType. Diff tabs open with activeTabType 'editor' but carry contentType 'diff', so the match never succeeded and the guard returned null - which is the reconciler's signal to fall through and activate a terminal. Every agent status echo republished the snapshot, so the diff lost focus ~300ms after opening, once per click. Same for conflict-review and check-details. Resolve the visible tab from group state instead, which is what is actually on screen and is the rule deriveActiveSurfaceForWorktree already uses.

Jinjing	3ac4171d14	fix(cmd-j): host-qualify worktree resolution and disambiguate list render keys (STA-4343) (#15371) ... * fix(cmd-j): host-qualify worktree identity to fix STA-4343 - Same repo::path across hosts now render as two distinct rows, each resolving to its own worktree on activation — closes wrong-host activation bug. - Disambiguate repeated persisted entry ids with render-key suffixes so React never leaves ghost rows mounted; prevents frozen display glitches when a session holds duplicate tab records. - Collapse query whitespace runs, treat emoji/symbols as content, deduplicate query tokens, and improve CJK compound matching in palette search. - Track filter-field cursor by option id rather than position so re-ranking after a toggle doesn't snap to the wrong row. - Dedup tabs by id at hydration so corrupt sessions don't render duplicates. * test(palette-search): add rankMode and current-state fields to palette o Adapt test fixtures and function calls to include new rankMode parameter and isCurrentPage/isCurrentWorktree tracking fields required by the palette search algorithm fix. * fix(palette-search): add host-qualified repo and worktree resolution Handle repo and worktree collisions in multi-host environments by querying host-qualified maps and comparing execution host IDs when determining current worktree status. Ensures the palette correctly displays repo identity and marks active status for worktrees across multiple hosts. * fix(cmd-j): namespace-safe duplicates and script-aware token matching - Carve out `palette-dup:` namespace for duplicate keys to prevent collision with real persisted ids, which previously could match generated keys like `id#dup1` - Gate reverse-containment token scoring to unsegmented scripts (Han, Hiragana, Katakana, Hangul), preventing false matches like "database" matching keyword "base" in Latin text - Host-qualify worktree identity in empty-query ordering to allow switching between same-id worktrees on different hosts, which were previously treated as duplicates (STA-4343) * Shorten comments in palette-list-entry-render-keys Replace verbose comments with concise one-liners per style guide.	2026-08-18 15:32:36 -07:00

Neil	4b2c901b66	test(terminal): pin that the CJK block is the preedit overlay, not the cursor (#15242) ... * test(terminal): pin that the CJK block is the preedit overlay, not the cursor A report described the cursor sitting on a wide character's first cell and hiding its right half, with cursor style and opacity settings ignored. Neither defect reproduces. Replaying the reporter's own captured byte stream leaves the cursor at column 11, exactly where the application asked, with correct wide and continuation cells. A block cursor also cannot hide half a glyph: it inverts the cell and the syllable renders inside the cursor span. The black block is the IME preedit overlay. macOS 2-set Korean keeps the trailing syllable composing until a terminator, so it sits in an opaque absolutely-positioned box over the grid rather than in the buffer. That box took stock upstream colours, black on white. It explains what no cursor theory can: the block appears at the composing cursor cell, no cursor option reaches it, it is identical with GPU acceleration off since it is a DOM node above both renderers, Latin never triggers it because Latin opens no composition, and Enter clears it because Enter commits the composition. Already fixed by the overlay theming in #15014, which landed a day after the reported release, so the fix ships in the next one. Tests only, no production change. Two pin the negative results so the cursor explanation cannot be re-derived, and one pins the actual mechanism at end of row, beside the existing mid-line arm. Separately confirmed and not fixed here: the WebGL renderer drops the cursor colour's alpha, so terminal cursor opacity genuinely does nothing for a block cursor, which is the default style on the default renderer. That is in the webgl addon rather than in xterm or in our code. Refs #12729 * test(terminal): make the cursor precedence assertion real and measure the overlay Review of the first pass found one assertion that could not fail. It set options.cursorStyle and then read decPrivateModes.cursorStyle, which are separate fields with separate storage, so it pinned that writing one does not clobber the other. Deleting the precedence expression from both renderers left it green. It now asserts the rendered cursor class: the option style renders, a DECSCUSR overrides it, and the reset hands control back. That fails if the precedence is removed. The overlay's rendered width is the one measurement in the report that argues against our explanation, and no test here could reach it, because the unit environment performs no layout. Adds an end-of-row browser arm beside the existing mid-line one, asserting a single composing Hangul syllable spans about two cells. That settles whether the block the reporter measured at one cell can be this overlay. Also scopes two DOM queries to the test container rather than the document, and attaches the render listener before writing so a missed render fails instead of hanging to timeout. Records in the file header what it does not establish: composing the opacity into the theme is not the same as it reaching the screen, since the webgl renderer drops the cursor colour's alpha for a block cursor.

OrcaWinandOrcaWin	6e8da1df8d	fix(wsl): pass guest argv verbatim through --exec (#15039) ... * fix(wsl): pass guest argv verbatim through --exec `wsl.exe <...> -- <argv>` expands `$name` in every argument against the guest environment before the guest ever runs. It does this even when no shell is involved, so `-- /usr/bin/printf %s '$HOME'` prints /home/you. Every WSL invocation went through that preprocessor, so scripts arrived already rewritten: `awk '{print $2}'` lost its field reference, and a POSIX script asking for the literal `$HOME` got the expanded path. `escapeWslShCommandForWindows` tried to compensate by escaping `$`, but it skipped any `$` preceded by a backslash, so a script containing `\$` was still corrupted -- and half the call sites never applied it at all. Route every invocation through `--exec`, which passes argv through untouched, and delete the escaper. The direct-git path already used `--exec`, so this is not a new compatibility dependency. A guard test fails if the `--` form reappears anywhere in the tree. Net -50 lines of production code. * test(wsl): drop remaining escaped-dollar assertions * fix(wsl): cover the --exec migration's blind spots An audit of every wsl.exe invocation found sites the first pass missed, including two it actively broke: - config/scripts/wsl-git-shell-benchmark.mjs imported escapeWslShCommandForWindows, which no longer exists, so the script threw on startup. Its wslShellArgs helper also still used `--`; the file already had an --exec helper, so route both call sites there. - classifySubprocessCommand unwrapped `wsl.exe <...> -- <binary>` by breaking on `--` alone. With every Orca spawn now on --exec it never found the guest binary and bucketed all WSL subprocesses as plain "wsl", losing the git/gh/glab breakdown. Break on either separator, since foreign wsl.exe processes still use `--`. CliSkillRuntimeSetup builds its setup command as a template literal rather than an argv array, so no array-shaped search could see it. Its decoder accepts both separators so commands persisted before this change still decode. The guard now scans config/ and tests/ as well as src/, and checks the command-string spelling alongside the argv one — the two shapes that have each shipped a regression. It skips comment lines so prose about the old form stays allowed, and asserts it scanned a plausible file count so a bad root cannot make it vacuous. * fix(wsl): restore the guard's multi-line sensitivity The guard matched line by line, so `'--',\s*'bash'` could not span a newline -- and every argv array in this repo is formatted one element per line, which is exactly the shape it exists to catch. Measured against the pre-migration tree it caught 17 files before and 9 fewer after. It now strips comment lines and matches the rejoined text, with a case that pins the multi-line shape so this cannot silently return. The program list is wider than shells now, which surfaced a false positive: tmux takes a `--` separator followed by a program too (`split-window ... -- cat`). Matching is scoped to files that mention WSL rather than narrowing the list back. Also: - Replaced the `sed` regression case, which was vacuous. A backreference contains no `$`, so it returned `bac` under both separators and would have passed without the fix. The block claimed every case proved the bug. Swapped in a positional argument and a shell local, both measured to differ -- the positional is the shape `wslUncDirectoryExists` uses, where `--` blanked `$1` so every existing directory probed as missing. - windows-shell-args.test.ts derived its expected argv from buildWslExecArgs, the helper under test, so six assertions would still pass if it regressed to `--`. Spelled the expectation out. - Dropped two comments citing the removed `--` behavior as rationale. --------- Co-authored-by: OrcaWin <293788423+OrcaWin@users.noreply.github.com>	2026-08-18 02:12:21 -07:00

When the client owns the key, buildMirroredAgentStatusPatch keeps the client's entry wholesale and copies only paneKey/worktreeId/tabId/providerSession off the host frame. lastAssistantMessage is hook-only content the byte pipeline can never see, and setAgentStatus writes payload.lastAssistantMessage straight through, so every OSC write also blanks it. The host publishes the text and the client receives it, then discards it on every republication — the remote agent row's message line is permanently empty while identity and status render fine (#12906).

Identity-only (`providerSessionOnly`) rows are tagged `kind: 'identity-only'` so future consumers do not each rediscover that they are not turn transitions. The staleness-decay contract is documented at the type: staleness must be computed against the same authority clock that stamped `observedAt`, or replicas must decay on local receipt time.

Neil	2b057eb21e	fix(terminal): end a url at CJK punctuation instead of swallowing it (#15240) ... Terminal URL detection treated every non-ASCII character as part of the url, so Japanese or Chinese text written straight after one was absorbed into the link. A line like PR: https://github.com/org/repo/pull/12345（作成済み・マージ待ち） underlined the whole run and opened the annotation percent-encoded onto the end of the url, which 404s. The body terminator listed only ASCII codes, so nothing at or above 0x80 could end a url. Terminating on all non-ASCII is the obvious repair and is wrong: a url path may legitimately carry unencoded CJK, and the wrapped-url tests cover exactly that - a real multi-line url whose continuation row is a Chinese path segment. That repair was written first and broke four of them. The distinction is punctuation, not ASCII. Non-ASCII punctuation, symbols and separators end a url; letters do not. Full-width brackets, an ideographic space, a full-width comma and the katakana middle dot are prose; 文档 in a path is not. Adds the extraction test file the module never had, covering the reporter's three cases, the CJK-path case that must keep working, and ASCII behaviour as a regression guard.

Neil	d143922561	fix(terminal): deliver an IME commit the deferred textarea diff missed (#15198) ... Picking a single Chinese character from the candidate window with a number key loses it. The character flashes and disappears. Picking the same candidate with the mouse works, and picking multi-character words with number keys works. Two paths can deliver an IME commit, and this falls between them. A keydown the input method consumed routes into a setTimeout(0) diff of the helper textarea, and that diff is what normally delivers the commit; xterm's _keyDownSeen guard exists to defer to it. When the commit arrives after that timer has already run, neither path delivers. Mouse selection works because no key is down, and a real composition session works because it takes a different path entirely. That narrows it to an input method whose commit round-trips asynchronously and which shows no in-application preedit. Track that a consumed keydown still owes its commit, and deliver only when the diff did not. The upstream guard and its single read site are untouched, which is what keeps the duplicate-commit behaviour it was added for sealed. Not doing the obvious repairs deliberately: clearing the flag, skipping it for keyCode 229, or setting it after the composition short-circuit each unblock the input path without retiring the diff, and all three were measured emitting the character twice. The patch and the lockfile hash here are generated. Review config/patches/xterm-src/@xterm__xterm@6.1.0-beta.287.src.patch, which is the hand-written source of the change; the shipped patch and both minified bundles are the regenerator's output from the pinned upstream build, so nothing in this change was hand-transcribed into a bundle.

Neil	598ba5d276	fix(terminal): stop the macOS IME forwarder from running on iPadOS (#15218) ... * fix(terminal): stop the macOS IME forwarder from running on iPadOS Korean typed into a terminal from an iPad web client arrives as loose jamo instead of composed syllables. The native-text forwarder is a macOS workaround: it claims a printable keydown and delivers the input method's substituted text from the input event alone. It stands aside for IME composition by checking isComposing and compositionstart. Touch iOS/iPadOS is unreliable about firing those for hardware-keyboard CJK input, so each jamo keydown is claimed as its own one-shot substitution rather than deferred to xterm's composition handling. It runs there at all because every iOS user agent contains "Mac" - "Macintosh" in iPad desktop mode, the default since iPadOS 13, and "like Mac OS X" in mobile mode. maxTouchPoints is the only signal a real Mac never sets. The Linux branch immediately below already makes the mirror-image exclusion for Android and CrOS; the Mac branch never got the same treatment. Gate the forwarder install only. isMac keeps its other five consumers - the Ctrl+C interrupt, clipboard bypass, JIS yen input and the standalone 229 keydown policy - which intentionally still treat an iPad with a hardware keyboard like macOS, matching iPadOS shortcut conventions. Without the forwarder, xterm's own composition path plus the deferred textarea diff is the sole delivery mechanism, which is already the arrangement on Linux. Not verified on hardware: the claim that composition events are absent on iPadOS is the mechanism the code supports and the only one matching the reported symptom, but no on-device capture confirms it. The platform detection stands on its own regardless. terminal-ime-input-context-refresh.ts has the same user-agent collision for its NSTextInputContext refresh. Narrower trigger surface, left for a follow-up. Refs #13345 * fix(terminal): require more than one touch point before skipping the forwarder The gate used maxTouchPoints > 0, which is looser than the idiom already in this repo. isIOSWebView in mobile/src/terminal/terminal-webview-html.ts requires more than one, because a Mac with a touch-capable peripheral can report exactly one, and such a Mac must keep the forwarder: it is a real Mac running the input method this workaround exists for. Under the old threshold that Mac silently lost native text substitution - a macOS regression introduced by a fix aimed at iPadOS. A captured iPad reports five, so the stricter bound costs nothing on the device this targets. The check stays user-agent based rather than adopting that helper's platform check, because an iPhone reports platform "iPhone" rather than "MacIntel" and would slip through.	2026-08-17 21:31:31 -07:00

Since `deriveGitRemoteIdentity` ranks `upstream` above `origin`, any repo whose top-ranked remote is `upstream` lost GitLab project gating entirely, so an exact URL for an unrelated project could surface that workspace. Return the `matchGitRemoteKeyParts` verdict directly. Resolved identities are re-probed on a 6h TTL, so a remote naming a different project is current evidence. `'unknown'` now means only "no identity" or "unexpanded SSH host alias", both of which stay permissive as before. * docs(cmd-j): correct the identity-freshness comments and drop a duplicate test The GitLab why-comment implied resolved identities refresh unconditionally. They only refresh when a repo/project list sweep finds one past its ~6h TTL (`selectEnrichmentCandidates` runs from `repos:list`/`projects:list`/ `projectHostSetups:list`, four refreshes per sweep, after a 5m startup delay); there is no background timer. State the accepted cost instead of implying the gate is loss-free. The GitHub-side comment still claimed the identity is "chosen when the repo was added and never re-probed" — the exact claim this PR disproves. Rewrite it to the reason that still holds (one stored remote hides a fork's `origin`). Behavior on the GitHub path is unchanged; it stays with the twin ticket. Delete `does not surface an upstream-identified repo for an unrelated project iid`: the inverted test above it already asserts both halves (mismatched project declines, the named project still matches) against the same upstream-derived identity.	2026-08-17 20:36:50 -07:00

Neil	f8e728bb8b	fix(watcher): watch the resolved worktree root so symlinked and differently-cased paths work (#15077) ... * fix(watcher): keep macOS FSEvents paths under the subscribed worktree root macOS FSEvents reports OS-canonical paths: symlinks resolved and every directory in its on-disk spelling. Linux (inotify) and Windows both rebuild event paths from the directory that was subscribed, so only macOS observes the mismatch. Orca's watcher contract is "event paths live under worktreePath". Consumers derive a worktree-relative path with relativePathInsideRoot(), which returns null when the event falls outside the root -- and a null relative path drops the event silently. So on a Mac whose worktree or folder path traverses a symlink (~/code -> /Volumes/..., anything under /tmp or /var), or is spelled with different casing than disk on a case-insensitive volume, every watcher event was discarded: the editor never reloaded an agent's edit, the File Explorer never refreshed, and Source Control never re-ran status. Nothing errored, which is why this looked like "the file watcher stopped working" on some machines and not others. Rewrite event paths back onto the subscribed root inside subscribeThroughWatcherSupervisor -- the single boundary every desktop, runtime-environment, and SSH-relay watch passes through -- so one change covers all three transports. The resolution runs alongside the subscribe rather than before it: an await ahead of the subscribe call lets a caller's abort land in a window where no watcher-process subscription exists to cancel, which hangs the existing cancellation contracts. The subscribe promise settles only after the rewrite is installed, and only after the subscription itself is recorded, so teardown never waits on a realpath. Matching folds per path segment (NFC + case) instead of by prefix length, because both folds change length and a folded-prefix length would slice the raw event path mid-character. Byte-exact fast paths run first, so unaliased roots -- every Linux and Windows watch, and most macOS ones -- cost one string comparison per event and allocate nothing. * fix(watcher): watch the resolved root so symlinked worktrees work on Linux too Verified on a real Linux host: @parcel/watcher passes IN_DONT_FOLLOW | IN_ONLYDIR to inotify_add_watch, so a symlinked worktree root fails outright with ENOTDIR ('Not a directory'). The watch never installs and Orca caches the root in unwatchableRoots, so it is never retried for that session. That is a worse symptom than the macOS path-spelling mismatch and hits Linux users of symlinked checkouts on every machine. Hand the backend the resolved directory instead of the caller's spelling, and keep mapping delivered paths back. Resolving the root also lets @parcel/watcher's own ignore paths match again on macOS, where they were computed from the unresolved root and silently excluded nothing. The resolve is synchronous on purpose. Every caller reserves and forks its watcher child in the same tick as the subscribe call -- capacity accounting and cancellation ordering both depend on it, and 30+ existing tests encode it -- so an await here would open a window where a subscribe is issued but no cancellable child exists. * test(watcher): use a directory junction on Windows so the alias repro runs there Creating a directory symlink on Windows needs elevation or Developer Mode, so the alias tests failed with EPERM on a real Windows host. A junction needs neither, is what users actually have (a junctioned C:\dev), and realpath resolves it identically -- so one fixture now covers all three platforms and the end-to-end repro no longer skips outside Linux and macOS. * test(watcher): pin the fabricated-path failure modes of the root rewrite A rewrite that returns a WRONG path is worse than no fix -- a consumer would act on the wrong file -- so pin the cases that could produce one: sibling directories that share a prefix with the root (POSIX and UNC), the root itself versus a shorter path, drive-letter casing, a root-only canonical path, and a script where toLowerCase changes length. Found by running the rewrite over an adversarial table; all already passed, so these lock in behaviour rather than fix it. * docs(watcher): drop an unverified claim about ignore paths I claimed resolving the root also repairs @parcel/watcher's ignore-path matching for aliased roots. Probing it on macOS shows the node_modules write is excluded either way: FSEvents resolves symlinks in its own exclusion paths, so the daemon filters at the source regardless of which spelling we subscribe with. On Linux the exclusions are userspace globs relative to the watched directory and there was no watch at all before this change, so there is nothing to compare. Removing the claim rather than leaving a plausible-but-wrong rationale in the module header. * refactor(watcher): simplify root path rewriter * test(palette): build searchable fixture documents	2026-08-17 18:42:49 -07:00

Neil	24e662adc1	feat(ssh): verify host keys, and restore panes correctly across a reconnect (#14844) ... * docs(ssh): design for real host key verification (STA-4319) Today's ssh2 verifier records a fingerprint and returns true — every host key is accepted, with no known_hosts consult and no change detection anywhere in src/main/ssh/. Scope is per-connection, so exec, SFTP, port forwarding, the watcher and relay deploy all ride that one unverified handshake, and the ProxyJump path puts the final hop — the topology most likely to cross untrusted network — on ssh2 specifically. Decisions worth calling out: - Read the user's known_hosts as a trust source but NEVER write to it. That file is shared with every other SSH tool on the machine; appending means line endings, permissions, concurrent writers and a corruption blast radius well beyond us. Accepted keys go to our own per-target store. Reading theirs is also the entire migration story: most developers already have their hosts there. - Mismatch is scoped to the SAME key type. A host with only an RSA entry that presents ed25519 is unknown, not changed. ssh2 negotiates ed25519 first, so without this we would fire a change-of-key alarm at nearly every existing user on their first upgraded connect — training them to dismiss the one warning that is supposed to mean something. Flagged in review as the decision I am least sure of; a downgrade-vector argument against it is being tested. - Changed key hard-fails with no override button; recovery is a separate explicit action, offered only when OUR store is what disagreed, because forgetting our record cannot unblock a known_hosts conflict. - Background reconnects deny rather than prompt. A dialog the user cannot place in context only teaches click-through. Two traps are documented because either would make the fix silently do nothing: an async verifier returns a Promise, which ssh2 reads as truthy and accepts immediately; and the existing test mock invokes hostVerifier with one argument and ignores the return, so it would pass against a verifier that never decides. Design only — no behaviour change. The doc is added to the tracked-reference allowlist in .gitignore alongside the other docs/reference entries. * docs(ssh): revise the host key design after security and migration review Three things the reviews changed, kept visible rather than quietly edited out. THREAT MODEL WAS WRONG IN THREE PLACES. Jump hosts are not the worst case — they are already safe: shouldUseSystemSshTransport branches on exactly the inputs resolveEffectiveProxy does, and attemptConnect returns after the system probe, so ProxyJump goes through OpenSSH and is verified. Agent forwarding was overstated (gated on the user's ForwardAgent). Credential theft was understated: any auth error counts as agent fallback, so a MITM walks the user to the password AND private-key passphrase prompts, and cachedPassword replays without prompting. The relay claim was backwards — the attacker owns their own machine; the real impact is the return direction, where they become the host our workspace trusts. TYPE SCOPING IS A DOWNGRADE VECTOR WITHOUT ALGORITHM ORDERING. This was the decision I flagged as least certain and asked to have argued both ways. OpenSSH is safe only because order_hostkeyalgs() puts known types first and RFC 4253 gives the client's order priority. ssh2 negotiates ed25519 first regardless, so an attacker who cannot forge the RSA key on file just presents ed25519 and gets a friendly first-contact prompt instead of a hard failure. Keep scoping, but set algorithms.serverHostKey to lead with the types on file — and add a sixth outcome for 'unknown type, known host', which must never read as first contact. SHIP THE DEFENCE BEFORE THE DIALOG. Startup restore fires eager connects for all targets in parallel with a 15s timeout while a prompt would live 120s; ephemeral VM targets present a new key every launch; paired-web connects run on the host desktop, so the dialog opens on someone else's screen. Phase 1 is therefore no modal at all: consult known_hosts and our store, match connects, unknown persists with accept-new semantics, mismatch and revoked hard-fail. That is the whole MITM defence with none of the migration risk. Also folded in, verified live against OpenSSH 10.2p1: the without-port fallback (bracketed lookup first, then bare, where the second pass can only yield match or unknown — otherwise a bare line plus a non-default port produces a spurious prompt); hashed entries hash the candidate form; multiple files union; a cert-authority line does not match a plain key. IPv6 and bracket parsing moved INTO scope — that is a parser requirement, not a scope call, and getting it wrong produces the prompt-training harm the design exists to avoid. * feat(ssh): parse and match OpenSSH known_hosts The matcher half of STA-4319. No behaviour change yet — nothing calls this. Hand-rolled because no maintained JS implementation exists, and written against behaviour observed from OpenSSH 10.2p1 rather than inferred from the man page. Three of those behaviours a reasonable reading gets wrong: - A non-default port is TWO ordered lookups, not one candidate set: '[host]:port' first, then bare host ('checking without port identifier' in ssh -v). The fallback pass can only yield match or unknown — OpenSSH downgrades a wrong key there rather than reporting a change. Collapse them and anyone holding a bare line who connects off-port gets a spurious first-contact result; treat the fallback as authoritative and they get a false change-of-key alarm. - Revocation resolves in its own pass so the verdict cannot depend on line order. Verified both orderings. - A cert-authority line never matches a plain host key; it only validates certificates. A normal line alongside it still decides. Mismatch is scoped to the same key type, and a host known by a DIFFERENT type returns unknown-type-known-host rather than plain unknown — an attacker who cannot forge the key on file must not get a friendly first-contact result by presenting another type. That outcome is only half the defence; the other half (leading serverHostKey with known types) lands with the wiring. 47 tests from vectors executed against real sshd, including ssh-keygen -H hashed entries. Each of six mutations reddens it: collapsing the passes, letting the fallback report mismatch, dropping type scoping, resolving revocation in line order, honouring an unrecognised marker, and skipping the blob/type agreement check. * feat(ssh): decide what to do with a presented host key The policy half of STA-4319, kept separate from the ssh2 wiring so it is testable without a handshake and injected rather than importing its sources, so a test states its own trust state instead of writing files. Phase 1 ships no dialog — a test asserts the decision is never 'prompt'. Startup restore opens every previously-active target at once, ephemeral VM targets would ask every launch, and paired-web connects run on the host desktop where the dialog would appear on someone else's screen. Ordering that matters: revocation outranks everything including StrictHostKeyChecking=no, because a revoked key is a statement that this key is known-bad rather than merely unrecognised. known_hosts is named before our own store on a change, because its remedy (ssh-keygen -R) is the one that also unblocks ssh and git — pointing at a remedy that cannot work is worse than none. Two carve-outs with reasons: an ephemeral runtime target accepts WITHOUT recording, since a fresh VM presents a new key every launch and a stored record would accumulate per launch and eventually read as a spurious change; and when ssh -G ran on the HOME-divergent path that suppresses /etc/ssh/ssh_config, an unknown host is denied, because a site-wide policy may forbid it and being laxer than ssh is the one outcome that is never acceptable. Rejection text deliberately avoids 'authentication failed' and 'permission denied': the reconnect ladder classifies on those substrings, so a denial phrased that way is retried forever against a decision that will never change. Pinned by a test. * feat(ssh): build the host key verifier and the algorithm order that makes it safe Still not wired into the handshake — that lands next. This is the piece that turns a decision into an ssh2 callback, plus the half of the design that is easy to forget because it lives in a different config field. The verifier MUST be a plain function returning undefined. ssh2 does 'const ret = verifier(key, verify); if (ret !== undefined) verify(ret)', so an async function returns a Promise — neither undefined nor falsy — and ssh2 accepts the key immediately while ignoring whatever the callback later decides. Making this async would silently restore exactly the accept-everything behaviour the module exists to remove, so a test asserts the return value is undefined. orderServerHostKeyAlgorithms is what makes type-scoped matching safe rather than a downgrade. RFC 4253 gives the client's algorithm order priority, so leading with the types we already hold for a host denies a server the choice of presenting some other type to convert a hard failure into first contact. Without it, an attacker who cannot forge the key on file just offers a different algorithm. Revoked entries never contribute to that order. Also fails closed on two paths that would otherwise hang or over-trust: a key whose own length-prefixed header cannot be read is refused rather than reasoned about, and a throw from any dependency denies, because ssh2 may not catch an exception raised inside the verifier and the handshake would hang instead of failing. 18 tests. Includes the two negative cases that matter — first-contact keys are recorded, but keys we already know, rejected keys, ephemeral runtime targets and a lax StrictHostKeyChecking are not. * fix(ssh): promote every RSA signature algorithm for a known ssh-rsa key A known_hosts entry names the KEY type, which is not the negotiated ALGORITHM name. One ssh-rsa key is offered as rsa-sha2-512, rsa-sha2-256 or ssh-rsa depending on the signature algorithm, so matching the literal name only would leave a host we know by RSA ordered behind ed25519 — precisely the ordering this function exists to prevent, and precisely the population (RSA-era known_hosts entries) it was written for. Verified from ssh2's own negotiation while wiring this: kex.js iterates the CLIENT list and takes the first entry the server also offers, so client order does decide, as RFC 4253 says. ssh2's default order leads with ed25519 and places the RSA algorithms fifth through seventh. * fix(ssh): verify host keys instead of accepting every one (STA-4319) The actual fix. ssh-connection's verifier recorded a fingerprint and returned true, so every ssh2 connection accepted every host key — no known_hosts consult, no change detection. It now consults the user's known_hosts plus our own store and refuses a changed, revoked or unverifiable key. Phase 1 by design: no dialog. Unknown hosts are accepted and recorded (accept-new semantics), because startup restore opens every previously-active target at once, ephemeral VM targets present a new key each launch, and paired-web connects run on the host desktop where a prompt would appear on someone else's screen. The MITM defence lands now; the prompt is Phase 2. Also sets algorithms.serverHostKey to lead with the types already known for the host. Without it the type-scoped matching is a downgrade — an attacker who cannot forge the key on file just presents another type and turns a hard failure into first contact. Verified from ssh2's kex.js that the client list decides. Denial replaces ssh2's generic handshake error with the specific reason, because the reconnect ladder cannot distinguish a generic failure from a transient fault and would retry forever against a decision that will never change. An unreadable trust store degrades to known_hosts only rather than failing the connect: a changed key is still refused, and a host trusted only by us falls back to first contact and is re-recorded, reaching the same decision. The ssh2 mock now uses the callback form and aborts the handshake on denial. As written it called hostVerifier(key) with one argument and ignored the result, so it would have passed against a verifier that never decides — flagged in the design as a mock that had to change, not a test to quietly rewrite. Two new tests pin the wiring rather than the module: an unidentifiable blob is refused, and a well-formed key is accepted. Note for review: commit 2d2a0880ba unintentionally swept in two modules built concurrently (ssh-known-hosts-source, ssh-host-key-store) because I staged with 'git add -A'; its message describes only the verifier. Both are covered by their own tests, but the attribution in that commit is wrong. 1461 SSH tests pass. * fix(ssh): bind the host key store to the active profile at startup Without this the store reports nothing trusted on every launch. Safe — known_hosts still decides, and a host trusted only by us degrades to first contact and is re-recorded — but it silently discarded our own accept records, so the store the design calls for was not actually in use. Bound beside the profile Store, since it is a sidecar of the same data file. Also records why the paired-web carve-out the migration review asked for is NOT implemented in Phase 1, rather than leaving it looking forgotten. That carve-out exists to stop a web client waiting out the 120s prompt timeout — a hang only reachable if a prompt exists, and Phase 1 has none, which the decision function pins with a test asserting it never returns 'prompt'. An RPC connect therefore behaves exactly like a local one. Adding a fail-fast path now would introduce a failure mode for a hang that cannot occur; it becomes load-bearing when the dialog lands and is listed under Phase 2. Noted there for whoever builds Phase 2: runtime/rpc/methods/ssh.ts already swallows the specific error and rethrows a generic one, so the host-key reason will not reach a web user without a change there too. Full unit suite: 52,352 pass. The 8 failures are the known environment baseline (5 osc8, 2 IME) plus one browser-cookie suite-ordering flake that passes in isolation — none in src/main/ssh, and none related to this change. * fix(ssh): close two downgrades the implementation review found Both were in my wiring, not the design, and two reviewers found the first independently. 1. OUR STORE WAS TYPE-DOWNGRADABLE. The inline lookup filtered by key type first and could only answer match/mismatch/unknown, so a record of a DIFFERENT type for the same endpoint read as "unknown". A host learned on first contact — ed25519, since ssh2 proposes it first — and absent from known_hosts could then be impersonated by presenting RSA: both sources say unknown, so accept-and-remember, silently. That is exactly the downgrade D3 says the design cannot ship without, applied to the records we create ourselves. The store's own isTrusted already computed the right answer and had no production caller. Stored types now also feed the algorithm ordering, without which the guard is only half present. 2. WE KEYED ON THE ORCA LABEL, NOT THE DIALED HOST. "ssh -G" echoes its own argument back as its hostname field when no Host block matches, so for a manual target that field IS the Orca label — the one name D2 forbids keying on, and one ssh never wrote. We consulted no entries at all, so an impersonated host read as first contact. Now keys on the dialed host, which buildConnectConfig has already resolved through HostName, with HostKeyAlias still winning. That inverted an existing test rather than deleting it: "uses the resolved hostname, never the Orca label" encoded an assumption disproved against OpenSSH 10.2p1, so it is renamed and reversed with the reason recorded in the test. 3. NO READABLE SOURCE IS NOT FIRST CONTACT. Every known_hosts file failing to read was indistinguishable from "this host is unknown", so a changed key would be accepted the one time we could not check. The loader now reports how many files it could read, and zero readable sources with an empty store takes the strict path instead of recording trust. 4. A superseded attempt's rejection could replace the live attempt's error, and substituting a new Error drops ssh2's code, so a transient ECONNRESET would stop being classified as retryable. The rejection is now local to its attempt. 5. displayHost was the Orca label, so a mismatch could print "ssh-keygen -R <label>" — a remedy that removes nothing. Also adds the tests that would have caught 1 and 2, the stale-attempt denial, and IPv6 literals, which the design moved into scope and nothing covered. 1,469 SSH tests pass. * fix(ssh): stop offering credentials to a host we just refused A refused host key ended the handshake and then fell into the credential ladder, because ssh2 reports a denied key as a generic auth failure and the passphrase branch is eligible on message shape alone whenever an encrypted identity file is configured. So the sequence was: decide this host may not be who it claims to be, then ask the user for their passphrase and hand it to it. Failing that, prompt for a password. Failing that, retry over the system ssh binary, which for a disagreement with our own store rather than known_hosts would simply connect. That inverts the point of checking at all. A denied key is now final for the attempt: recognised by type before any fallback runs, and again inside the agent-fallback retry, which re-runs the handshake and so can be the attempt that denies. Two things had to change for that to hold. The rejection is now a HostKeyVerificationError rather than a rebuilt Error, so the connect path recognises it by type. Substring matching would have worked today and quietly stopped working the first time a reason string was reworded — and these strings are already worded around the auth-error classifier, so they are exactly the kind that get edited. And the verifier now reports the denials that skipped the policy: an unreadable key blob and an internal failure both denied without calling onDecision, so the connect path saw only ssh2's generic failure and walked the ladder. That was the actual path the new test hit first. The report carries no fingerprint, since there is no host key to identify, and the connection no longer overwrites the fingerprint it holds with an empty one — the relay keys install-lock isolation on that value. The reconnect ladder also refuses to retry it. Its classifier is otherwise substring-driven, so a reason containing "connection reset" would have been retried until the ladder gave up, burying the reason under nine attempts. Tests: no credential prompt after a refusal, an encrypted key configured so the passphrase branch is eligible; refused reports as 'error', not 'auth-failed', which would invite the user to re-enter credentials that are not the problem; no retry; both bypassing denials report; a throwing listener still denies rather than hanging the handshake. Also drops three test files a bisect resurrected from before the revert that deleted them. 172 tests pass across the three touched files; typecheck and lint clean. Pre-existing on origin/main and untouched here: 3 failures in ssh-connection-sftp-namespace.test.ts. * fix(ssh): stop treating an absent known_hosts as a source we failed to read The previous commit's "no readable source is not first contact" guard was right about the danger and wrong about how to detect it, and the version that shipped would have refused every connection a new profile ever makes. A file that does not exist and a file that refuses to open both arrive as a rejected readFile, and I counted them the same way. They are opposites. An absent known_hosts is the normal state — ssh creates it on its own first connect, and an Orca profile that has never connected has none — and it is real evidence that no host is known. A file that exists and will not open is evidence withheld: the entry that would have said "this key changed" may be sitting in it. The default list is the reason this was fatal rather than obscure. It always names known_hosts2, which essentially never exists, so on a machine with a normal known_hosts the count was 1-of-2 and everything worked; on a fresh profile it was 0-of-2 and every connect failed with "the system SSH configuration could not be read" — a message about a file the user does not have and an error they cannot act on. The suite passed only because the machine running it happens to have a known_hosts. Pointing HOME at an empty directory fails 62 connection tests, which is what the new wiring test does. So the count is now unreadableFileCount: files that exist and could not be read, which is the condition the guard was always trying to express. Any one of them takes the strict path; an absent or empty file takes none. The store clause is gone with it — a store hit already returns accept before this is consulted, so it never changed an outcome. Tests: absent, empty, permission-denied, directory, and all-parsed at the source; first contact with no known_hosts at all at the wiring level. 1,482 SSH tests pass. The 3 failures in ssh-connection-sftp-namespace.test.ts are pre-existing on origin/main and untouched here. * fix(ssh): let an ephemeral runtime outrank sources we could not read Three things, all about the same question: when we cannot see everything that decides a host key, what does that actually license us to refuse? 1. ON-DEMAND RUNTIMES WERE REFUSED FOR A POLICY THEY COULD NEVER SATISFY. A machine provisioned a minute ago cannot be in known_hosts, by construction — which is why it has a carve-out at all. But the carve-out sat BELOW the incomplete-sources check, so anyone whose HOME diverges from their passwd home (sandboxes, our own E2E isolation) took the `-F` path, and every on-demand runtime connection was refused, pointing at a config file the user cannot fix. Refusing there buys nothing. No policy, seen or unseen, is satisfiable by a host that did not exist yesterday; the trust comes from the provisioning channel. So the carve-out now outranks it. An EXPLICIT StrictHostKeyChecking=yes still wins over both — that one we can read, and the user asked for it. 2. THE FLAG WAS NAMED FOR ONE OF ITS TWO MEANINGS. `siteConfigSuppressed` started as "-F hid /etc/ssh/ssh_config" and had since grown "a known_hosts file exists and would not open" — which is not a site config, and reading the name in the decision function told you nothing about why an unreadable file landed there. It is `verificationSourcesIncomplete` now: we could not see something that decides this, so do not extend NEW trust. A host we already know still connects, because a match is decided before this is reached, and that is now pinned by name. 3. THE COPIED ssh2 ALGORITHM LIST HAD NO DRIFT ALARM. We reorder ssh2's default host-key proposal, which meant hand-copying a list ssh2 exports only from a deep internal path. ssh2 throws `Unsupported algorithm` on anything outside its supported list, so drift does not degrade — every target stops connecting, before a socket opens, with a message about an algorithm the user never chose. Worth knowing that the list is also built conditionally on ed25519 support. Kept as a literal rather than a deep import, since silently adopting a new proposal order is the wrong default — the order is what makes type-scoped matching safe, so a change deserves review. A test now compares it against ssh2's real constant and checks every entry is one ssh2 accepts. Moved next to the ordering function it feeds, and out from between the import statements. 1,488 SSH tests pass. The 3 in ssh-connection-sftp-namespace.test.ts are pre-existing on origin/main. * docs(ssh): record what review changed and the STA-4319 follow-ups The design survived implementation; every defect found afterwards was in the wiring. Worth recording the pattern, because it repeated five times: each one made us either blind or unusable, never subtly wrong — and four of the five broke legitimate hosts rather than admitting bad ones. Action items separate the things Phase 2 must decide (UpdateHostKeys, which is now the likeliest way a legitimate user meets a rejection; the web client never seeing the reason; RPC fail-fast) from the gaps Phase 1 knowingly accepts (WSL, CheckHostIP, ca-only hosts, the hand-copied ssh2 algorithm list). Also flags the rollout risk plainly: this is the first release in which Orca can refuse an SSH connection at all. * test(ssh): pin the ephemeral carve-out where it is actually observable The first version of this test asserted an on-demand runtime connects on first contact, which every target does — it would have passed with the carve-out deleted. Pointing HOME at a home whose known_hosts exists and will not open makes the two cases diverge: a normal target is refused there, an on-demand runtime is not. Removing the carve-out now fails three tests instead of none. Also covers the wiring for the unreadable-source refusal itself, which until now was only pinned at the decision level. * test(ssh): pin the parser against real ssh -G output, and accept-new against ask Two gaps the audit named. The ssh -G fixtures were all hand-written, which means they encode what I expect ssh to print. This one is verbatim OpenSSH_10.2p1 output for a Host block using HostName, HostKeyAlias, StrictHostKeyChecking accept-new, two UserKnownHostsFile paths and a non-default port. The format detail that matters: each file list arrives space-separated on ONE line, so reading it as a single path would consult nothing for anyone with more than one file configured. And accept-new was untested despite being a real OpenSSH value. It currently behaves identically to ask, which is exactly right while no dialog exists and is what lets the defence ship without a modal — so the equivalence is now pinned, and Phase 2 has to break it deliberately rather than discover it. Plus a guard that accept-new never falls into the strict branch. * test(ssh): cover the wire from an accepted key to a record on disk Nothing covered the store end to end. Every connection test runs with it unwired — a real path, since it degrades to known_hosts only — so an accepted first-contact key was never observed becoming a record, and the record was never observed being believed on the next connection. Without that wire the store is dead weight: an unknown host connects every time and is never learned. Its own file for two reasons. initSshHostKeyStoreFile binds module-level state for the rest of the process, and binding it makes the connect prelude do real disk I/O — which the shared suite cannot absorb, because its reconnect tests drive the clock with fake timers and an fs round trip does not complete inside an advanced tick. Adding these there turned 12 unrelated tests red. Covers: the record is written; it is read back as a match; the same key is not recorded twice; a DIFFERENT key for a host we recorded ourselves is refused (the store's entire security value, and a case known_hosts cannot catch since it has never heard of the host); and an on-demand runtime records nothing. Stubbing rememberHostKey to a no-op fails four of the five. * fix(settings): stop truncating the SSH connection error to one line The host key messages are written to be actionable — a mismatch ends in "Run: ssh-keygen -R <host>", which is the remedy that also unblocks ssh and git. The only place in the renderer that displays an SSH connection error clamped it to a single line with `truncate` and carried no title attribute, so the remedy was unreachable, not even on hover. The careful wording reached a CSS ellipsis. Wraps instead, with [overflow-wrap:anywhere] because a long hostname offers no break opportunity and would overflow the column on its own. The paragraph only renders on failure, so the extra height costs nothing in the normal case. CORRECTION to the four preceding commits: they each claimed 3 pre-existing failures in ssh-connection-sftp-namespace.test.ts. That was my error — I had been running `npx vitest` without `--config config/vitest.config.ts`, so the project's setupFiles and execArgv were absent. Under the real config those 3 pass, and have throughout. The whole SSH suite is green: 1,504 passed, 13 skipped. Still failing on this branch and unrelated to it (different subsystems, no file overlap): 5 in terminal-snapshot-osc8-roundtrip and 2 in browser-cookie-import. * fix(terminal): show why the SSH connection failed, not just that it did The reconnect overlay took only a status, so every failure rendered the same sentence: "The SSH connection to devbox failed. Connect again to continue this terminal session." A refused host key and a network timeout were indistinguishable there, and the host key message — the only place that names the remedy, down to `ssh-keygen -R <host>` — reached no terminal user at all. The state carried it the whole way; the overlay simply never asked for it. Adds it as a second line rather than replacing the sentence. The sentence says what to do, the detail says what happened, and keeping both means an errno failure does not lose its guidance to make room for "connect ETIMEDOUT". Wrapped, for the same reason as the settings card: the remedy is at the end. Suppressed for a removed target, which already explains itself and can never reconnect — a stale connection error underneath would contradict it. The new selector mirrors selectRuntimeAwareSshStatus branch for branch, including the unreachable-environment and un-hydrated-bucket nulls, so the pair cannot disagree about which source they read and a detail is never shown next to a status it did not come from. Known and NOT addressed here: "Connect again" is still the wrong advice for a decision that will never change. Telling those apart needs a typed reason on the wire rather than a string, which is a remote-wire-compatibility decision; it is recorded in the STA-4319 follow-ups. Pre-existing on this branch and untouched: 2 failures in terminal-ime-xterm-resumed-preedit-visibility. * docs(ssh): record where the rejection message actually lands Traced end to end, because a rejection the user cannot read is a half-shipped feature — and two of the surfaces were dropping it entirely, both now fixed. What is left is written down rather than guessed at: the status bar renders only 'Error', the terminal overlay's call to action still invites a retry that cannot succeed, toasts carry Electron's remote-method prefix, and the paired-web path replaces the text with 'SSH connection unavailable' on every route — which also affects a DESKTOP user viewing a host owned by a remote Orca server, not just web clients. * refactor(ssh): give the store one matcher instead of two The connect path had its own copy of the store comparison, because ssh2's verifier decides synchronously and cannot await the file, so records are preloaded. That copy is precisely where the type downgrade came from: it answered only match/mismatch/unknown, so a record of a different type for the same endpoint read as first contact and a host learned on first contact could be impersonated by presenting another key type. Fixing it left two implementations that have to agree forever, which is the same bug waiting to happen. matchTrustedHostKeys is now the single pure matcher; isTrusted is a load plus a call to it, and the connect path calls it directly on preloaded records. Same for the key types that feed the algorithm ordering, which the connect path was also filtering by hand. The two copies had in fact already drifted: the connect path lower-cased the query host where the write trims AND lower-cases. Not reachable today — the host is trimmed before it reaches there, which I confirmed by mutating the normalisation and watching the wiring test pass anyway. So this is not a bug fix, and the wiring-level test I first wrote for it proved nothing and is gone. The unit test that replaces it drives the matcher directly, where the input is mine to control, and it does fail when the normalisation diverges. Also adds an equivalence test across all six outcomes between the preloaded and awaited paths, so the two can never answer differently again. Restores the local name siteConfigSuppressed for the `-F` check; it was renamed along with the decision input, but at that site it really does mean only the one thing, and the union with the unreadable-file count happens one line later. 1,509 SSH tests pass. * test(ssh): check the matcher against a live OpenSSH client, not against my beliefs Every other test in the parser file states what I believe ssh does. These state what it did: an OpenSSH 10.2p1 client against a real sshd on 127.0.0.1:2222, with the client's own verdict recorded from its output, and ssh-keygen -H's own salt and hash pinned as a vector. Two assumptions the design leans on were worth more than an argument. THE FALLBACK PASS MAY NOT REPORT A CHANGE. We look up `[host]:port` first and retry the bare host, and only the first pass may answer `mismatch`. With StrictHostKeyChecking=accept-new, a bare line holding a DIFFERENT key, dialed on 2222, ssh connected and appended a new `[127.0.0.1]:2222` line — no IDENTIFICATION HAS CHANGED banner. It read that as first contact. Had we reported a change there we would refuse hosts ssh connects to happily, and the wrongness would have been invisible: refusing looks like the cautious choice. AND THE TYPE-SCOPING REJECTION IS NOT AN INVENTION. known_hosts holding an ssh-rsa key while the server offers ed25519 makes ssh print IDENTIFICATION HAS CHANGED and refuse. So unknown-type-known-host is neither stricter nor laxer than ssh — treating it as first contact, which is what a naive type-scoped lookup does, is the laxer mistake. That second result also fixes the message. ssh is blocked too, so `ssh-keygen -R <host>` is the remedy that unblocks both, and we were naming it only for a same-type mismatch — leaving this case with a diagnosis and no way out. Named now when known_hosts is the source that disagrees, and still not named when it is our own store, which ssh-keygen would not touch. 1,516 SSH tests pass. * docs(ssh): record the two assumptions a live client confirmed Both were load-bearing and neither was obvious: the bare-host fallback pass may not report a change, and unknown-type-known-host is what ssh itself does rather than something we invented. Getting the first backwards would have refused hosts ssh connects to happily, which is the failure mode that looks like caution. * style(ssh): satisfy the code-quality lints in the two new test files A string concatenation that should be a template literal, and an inline import() type annotation that should be a type-only namespace import — erased before vi.mock's hoisted factory runs, so the mock is unaffected. pnpm lint is clean. * fix(ssh): honour StrictHostKeyChecking, which had never once been read correctly `ssh -G` does not echo the value the user wrote. StrictHostKeyChecking is rendered through fmt_multistate_int, which prints the first entry of multistate_strict_hostkey, and that table lists true/false before yes/no: yes -> true | no -> false | off -> false | accept-new -> accept-new | ask -> ask Verified against OpenSSH 10.2p1 from both a config file and -o. Not 10.2-specific; the table ordering is old. The decision function tested only 'yes'/'always' and 'no'/'off' — spellings that cannot arrive. So `StrictHostKeyChecking yes` fell through to the default branch and we accepted AND PERSISTED a host the user's config explicitly says to refuse. That is the worst outcome this feature can produce, and it was the behaviour for every strict user from the first commit. `no`/`off` landed there too, breaking the documented "lax settings never persist" invariant. Every unit test passed throughout, because they fed the function 'yes' — the value a human writes, not the one that reaches the code. My ssh -G parity test did capture real output, but I happened to configure accept-new, one of only two values that round-trip unchanged. The new table is keyed on configured value -> what ssh -G actually prints, and asserts both reach the same verdict, so the question "is this the spelling that arrives?" cannot be assumed again. Found by a parity review against a live OpenSSH client. * fix(ssh): stop the fallback pass accepting a changed key, and refusing a new one One wrong loop scope, two opposite errors, both reproduced against a live OpenSSH 10.2p1 client and an ed25519-only sshd on 127.0.0.1:2223. ACCEPTING A CHANGED KEY. ssh runs the bare-host fallback only when the port-qualified lookup matched no plain entry of ANY key type. We ran it unless pass 0 produced a match or a SAME-TYPE mismatch. So with an off-port RSA entry plus a bare, correct ed25519 line — an ordinary shape, an old off-port entry beside one written by a port-22 connect — ssh printed IDENTIFICATION HAS CHANGED and refused, with no "checking without port identifier" in -v because the fallback never ran, while we reached the bare line and returned `match`. REFUSING A NEW ONE. sawKnownHostOtherType and sawCertAuthority were declared outside the pass loop, so an entry found only on the fallback pass could set them. A bare ssh-rsa entry, dialed on a non-default port against an ed25519-only server, made ssh add the host and connect — plain first contact — where we returned unknown-type-known-host and hard-failed. That is Gitea/Forgejo, dev containers, Gerrit, Vagrant: an off-port service on a host already in known_hosts. So the flags are per-pass now, and pass 0 decides as soon as it finds any plain entry for the host. Which of the two rejections it reports only picks the message; ssh calls both HOST_CHANGED. Also drops the type check from the match test: byte equality already implies the types agree, because the blob carries its own algorithm name and parsing rejects any line whose declared type disagrees with it. Reverting either half of the scope fix fails exactly the two new tests. 1,526 SSH tests pass. * fix(ssh): refuse the known_hosts lines ssh itself refuses to parse Three ways a line could be trusted by us and invisible to the user's own ssh — or, worse, raise a CHANGED alarm from an entry ssh drops. Buffer.from does not fail on bad base64, it SKIPS invalid characters, so `<key>!!!` and a blob with `@@` spliced into it both decoded to the correct key and matched. Verified live against OpenSSH 10.2p1 on 127.0.0.1:2224: the unmodified control reached authentication and all three malformed variants produced "No ED25519 host key is known". A re-encode-and-compare makes us agree. `<key>AAAA` is the interesting one, and the reason the first fix was not enough: 68 characters plus 4 is still legal base64, and the algorithm header still reads ssh-ed25519, so neither the base64 check nor the existing header check sees anything wrong. ssh parses the whole key structure. We decoded 54 bytes where an ed25519 key is 51 and reported `mismatch` — a man-in-the-middle warning caused by a typo in a file ssh silently ignores. So the blob is now walked as what it is: a run of length-prefixed fields that must consume it exactly. Algorithm-agnostic on purpose, so a key type we do not model is checked as well as one we do. It also rejects a length prefix that overruns the buffer, which readHostKeyType only checked for the first field. And ssh's extract_salt demands exactly one SHA1 digest — "expected salt len 20, got 16" — where we accepted any non-empty salt. A short salt is still a usable HMAC key for us, so a hand-crafted line could match for us and be a parse error for ssh. ssh-keygen -H always writes 20 bytes, so refusing loses no real entry. Worth recording that ssh-keygen -F cannot answer any of this: it matches host names and prints lines without ever decoding the key, so it reports "found" for all four blobs. The real client was the only instrument that worked. Found by a parity review; the base64 finding as reported was right about the behaviour and wrong about the mechanism for the padded case, which is what led to the structural check. 1,533 SSH tests pass. * fix(ssh): name a ssh-keygen -R target that actually removes the entry Verified against OpenSSH 10.2p1: with both `[h.example]:2222` and `h.example` on file, `ssh-keygen -R h.example` removes only the bare line and leaves the bracketed one — and there is no port flag, `-R host -p 2222` is "Too many arguments". An off-port target is keyed `[host]:port` in known_hosts, so the command we printed removed nothing: the user runs it, reconnects, and meets the identical failure with no indication of why. The message now names the bracketed form, quoted because the brackets are shell glob characters, whenever the port is not 22. Found by a parity review. * fix(ssh): read ssh2's host key algorithm list instead of copying it ssh2 builds DEFAULT_SERVER_HOST_KEY at load time and prepends ssh-ed25519 only when a RUNTIME PROBE succeeds — it signs and verifies with a fixed Ed25519 key. On a build where that probe fails, ssh-ed25519 is absent from ssh2's SUPPORTED list too, and generateAlgorithmList throws `Unsupported algorithm: ssh-ed25519` from inside client.connect. That throw matches no retry classifier and no transport-fallback classifier, so it is permanent — and because we only set `algorithms` for hosts we already know, it would fire on trusted hosts while new ones kept working. A copied list cannot be merely stale here; it can be wrong. So it is read from ssh2 now, which also removes the drift risk the previous commit could only report. ssh2 is external in the main bundle and the bundle is CJS, so the deep path resolves at runtime from packaged node_modules. The copy stays as a fallback in case a future ssh2 moves the file — losing the proposal order degrades the type-scoping guarantee, but refusing to connect at all is worse. The test that used to pin the copy against ssh2 now pins the fallback, which is the only part that can still drift. Found by an availability review. pnpm lint clean; 1,537 SSH tests pass. * fix(ssh): look a HostKeyAlias up the way ssh does — without the port HostKeyAlias suppresses the port entirely. Verified against OpenSSH 10.2p1 on port 2225 with HostKeyAlias=myalias: an entry keyed `myalias` authenticates, and one keyed `[myalias]:2225` gives "No ED25519 host key is known for myalias". We built [['[alias]:port'], ['alias']] and consulted a form ssh never writes. On its own that was a stale-entry false alarm. The previous commit made it worse: now that the first pass decides as soon as it finds any entry for the host, a leftover `[alias]:2225` line STOPS the bare lookup ssh actually performs — so the one population D2 cites HostKeyAlias for, bastions tunnelled through localhost:port, would get a hard failure on a host ssh connects to. So resolveKnownHostsLookupHost reports whether the name came from the alias, not just what it is, and that flag reaches both the matcher and the algorithm ordering. Returning the name alone is what made the bug invisible: the caller had no way to know it was holding something that must not be bracketed. Found by a parity review. 1,543 SSH tests pass. * fix(ssh): only claim the site config was suppressed when ssh -G actually ran sshGArgsForHost reports which arguments WOULD be used, not what happened. It returns the -F form whenever ~/.ssh/config exists and os.homedir() diverges from the passwd home, so a machine with no usable ssh at all — Windows without OpenSSH, a restricted sandbox, a timed-out probe — was judged by whether it happens to have a ~/.ssh/config, and rejected every unknown host permanently if it did. The same broken machine WITHOUT one stayed fully permissive, which is the tell: the flag is a claim about a config file we could not read, and when ssh never ran there is no such claim to make. Narrow but total where it lands: anything that sets HOME explicitly (wrapper scripts, sudo -E, devcontainers), macOS mobile and network accounts, and the E2E isolation this branch was written for. Found by an availability review. * fix(ssh): stop refusing hosts that ssh itself connects to Two product decisions, both taken deliberately after a review priced their blast radius, and both moving us from stricter-than-ssh to matching it. CERTIFICATE-AUTHORITY HOSTS NO LONGER FAIL. The point of an SSH CA is that the client holds ONE line — very often `@cert-authority *` — instead of per-host entries. That line matches every candidate, so for a Teleport / Vault-SSH / Smallstep / in-house-CA user EVERY target failed, not just CA-signed ones, including on-demand runtime VMs, and StrictHostKeyChecking=no did not help. The documented escape was an environment variable, which an Electron app launched from the Dock or Start Menu never sees. Meanwhile OpenSSH, verified live, treats a CA-covered host presenting a plain key as first contact and connects: ssh2 cannot validate certificates at all, so refusing bought nothing ssh was not already giving up. The residual risk is real and accepted — for a CA-protected host we take a plain key we cannot tie to the CA — and the ca-only outcome is carried through the decision so it stays visible in the log. AN UNREADABLE known_hosts NO LONGER REFUSES EVERYTHING. Any non-ENOENT read error on any configured file rejected every unknown host, with a message blaming the system SSH configuration, which was not what happened. The common trigger is not exotic: a Windows OneDrive Known Folder Move placeholder while offline fails with a cloud-file error, not ENOENT. It was also asymmetric with our own store, which degrades an unreadable file to "nothing trusted" and connects. We now connect as ssh does — it warns and treats the host as unknown — but record NOTHING, so a first contact we could not check never becomes durable trust. That second half is the reason the first is acceptable, so it is pinned end to end with the store actually bound. Which meant splitting verificationSourcesIncomplete back apart. It had been one flag for two claims that now diverge: "a site policy may exist that we cannot read" still refuses, "a file we could not open may contradict this" does not. Merging them was what made the second inherit a strictness only the first justified. Both still lose to evidence we DID read: a mismatch, a revoked key, or an explicit StrictHostKeyChecking still refuse in either state. pnpm lint clean; 1,549 SSH tests pass. * docs(ssh): correct the design where a live client disproved it D2, D3 and D4 each stated something about OpenSSH that turned out to be wrong when tested against a real client and sshd rather than read from the source. D3's premise is the notable one: OpenSSH is not type-scoped at all, so it does not avoid the RSA-era false alarm the way the doc claimed. It avoids the situation via order_hostkeyalgs and hard-fails when the situation arises anyway. The conclusion survives — the ordering is still what makes our scoping safe — but for a different reason than the one written down, and a reader would have drawn the wrong lesson. D2 gains the two rules that actually bite: the entry condition to the fallback pass, and HostKeyAlias suppressing the port. D4 records both reversals with their reasoning and the residual risk each one accepts, and the ssh -G spelling trap that made StrictHostKeyChecking dead on arrival. Corrections are kept visible rather than edited out, per the note at the top of the file. * fix(ssh): repaint the panes after a reconnect, not just reattach them Reported: disconnect an SSH host from the Remote Hosts popup, reconnect, and the terminals come back blank — but resizing a split or toggling the sidebar makes them render correctly. That last detail is the diagnosis. The panes were never broken: reattach restores each pane's buffer but not its painted frame. xterm repaints on a write or a resize, and a reconnect produces neither for a pane that was already correctly sized — so nothing paints until a relayout forces it, which is exactly what resizing or toggling the sidebar does. The renderer already has refitAndRefreshAllTerminalPanes for this shape ('after bulk desktop restore, background panes may have correct cols/rows but a stale xterm renderer until focus forces a repaint'). Its only callers were the mobile fit-reclaim paths; the SSH reconnect path never used it. Scheduled from finalizeHydratedTerminalPanes, on both a frame and a 100ms settled pass — the same pattern the desktop-restore path uses, because rAF alone lands while panes are still remounting. Mutation-proved: removing the schedule reddens the new test, which is the reported symptom. * fix(ssh): repaint background-tab panes revealed after a reconnect Completes 834a495038, which only fixed the ACTIVE tab. Reported: split panes of plain shells on another tab were still blank after reconnect until a divider drag or a sidebar toggle. The repaint did reach background managers — they stay mounted, only rendererVisible flips — but it could not land. A tab-hidden pane measures as a 0-size box, so canMeasurePaneForFit bails and the fit is a no-op, and refreshAllPanes marks rows dirty on a pane with no presented frame, which cannot repair a grid the reattach's direct terminal.resize left diverged. The reveal then takes the light resume path, which deliberately does not fit, and scheduleRevealRepaint only reattaches WebGL. So nothing ever fixed the geometry — and a divider drag or sidebar toggle is a real fit, which is why those appeared to work. Parks the repaint on a hidden manager and replays it on reveal, reusing the existing reveal-fit machinery rather than adding a mechanism. Flag-gated so the light path still does not fit in the ordinary case — 'does not fit on a light tab reveal' stays green. Splits are not special: the gap is per-manager, so it is identical for 1 or N panes. Splits just expose it, because users find the workaround (drag a divider) that a single full-tab pane rarely gets. A never-mounted tab is unaffected — it has no live manager and fits through the normal initial-fit lifecycle. Mutation-proved twice: removing the deferral, and reverting the reveal-side condition. Each reddens only the new tests. * test(terminal): pin that panes are PAINTED, not merely bound — and fix a broken commit Two problems, both mine. 1) 0103a80b48 swept in an untracked fixture and left the branch failing typecheck (unused Terminal import in painted-pane-fixture.ts). Its canvas stub also threw 'clearRect is not a function' on every refresh. Fixed here. 2) direct-ssh-reconnect-repaint.test.ts, which I wrote to guard the reconnect repaint, is VACUOUS: it re-implements finalizeHydratedTerminalPanes inside the test and mocks the registry, so deleting the real fix from useIpcEvents leaves it green. direct-ssh-reconnect-repaint-wiring.test.ts replaces that guarantee by capturing the real callback the hook hands the coordinator and running it against live panes — deleting the two scheduling lines now reddens it. The gap this closes: content survival was already well covered at the BYTE layer (snapshot roundtrip, hide/reveal stitching, cold-restore scrollback), but every pane test stubbed terminal as {cols, rows, refresh: vi.fn()}, so 'repainted' only ever meant 'a spy fired'. No test ran a real xterm through a real PaneManager. pane-content-survival.test.ts does, reading .xterm-rows — what the user actually sees — across reconnect, restart-shaped restore, tab reveal, window show, split and unsplit, for plain shells and alt-screen TUIs. The alt-screen distinction is now pinned explicitly: forcing a resize inside fitAllPanes reddens only the TUI test, because a plain shell reflows and survives while a TUI frame does not. That asymmetry is why the reported bug looked like a plain-shell problem. 11 tests, each mutation-proven to redden only its own. 760 pane-manager tests green; the 2 failures here are the known environmental IME baseline. Flagged, not fixed: the unsplit path reparents the DOM without the dispose/ reattach that splitManagedPane does explicitly because 'DOM reparenting can silently invalidate a WebGL context without firing contextlost', and follows it with a safeFit that no-ops when the box is unchanged. Same shape as the reconnect bug. happy-dom has no WebGL, so only a real-GPU E2E can confirm it. * fix(ssh): send the pane its screen back on reconnect A reconnect left every remote terminal blank. Measured on a live relay, not inferred: pty.attach returned no replay for every pane, taking the activation === 'existing' early return in the relay's attach. 'existing' means a source delivery is already open for this client, so it must already be receiving live output and cannot need its screen re-sent. That holds for a duplicate attach. It is false for a reconnect, for a reason neither side can see alone: the client keeps its id across the drop (detachClient refuses to detach the primary, and setWrite revives that same id) so the delivery outlives the dead transport, while the RENDERER has already thrown its terminal away. A reconnect bumps tab.generation, which is the pane's React key, so TerminalPane remounts and the old xterm is disposed with its buffer, and nothing on that path captures it first. Both halves are individually reasonable and together they guarantee a blank pane: the relay reports the client already has the screen, to a client holding a brand-new empty terminal, and nothing paints until new output happens to arrive. Resizing appeared to fix it only because a TUI redraws itself. So the client says which case it is. reattachSshPtySession is by definition painting into a new terminal, so it asks; nobody else does, and the early return keeps working for them. Optional on the wire, so an older relay ignores it and behaves exactly as it does today. Falling through rather than returning the replay inline is deliberate: the path below already drops the pending batched bytes that are also in the buffer, which is what stops the live delivery rendering them twice. Reproduced first as a test against the real dispatcher, source publication and PTY handler (the second attach for one client, which is what a reconnect is) and it fails on the exact symptom before the fix. A second test pins that a caller which does NOT ask still gets nothing, so this cannot become a double-render for the duplicate-attach case the early return exists for. Also updates four provider tests that assert the exact attach params. NOT yet verified in the running app; the log will show replay=true on reconnect. * chore(ssh): drop the temporary reconnect-replay diagnostic Served its purpose: it is what turned 'the panes look blank' into replay=false, replayLen=0 on every pane, and then into replay=true with real byte counts once the relay fix landed. The permanent log line keeps the boolean, which is the part worth having. * revert: drop the reconnect repaint commits; they cannot fix the blank panes Reverts 2fdab478c0, 34fc1424f0 and dc6f6bf685, which I cherry-picked onto this branch to test alongside the host key work. Their stated premise is 'reattach restores each pane's buffer but not its painted frame'. That is false for this flow: a reconnect bumps tab.generation, which is the pane's React key, so TerminalPane remounts and the old xterm is disposed WITH its buffer, and nothing on that path captures it first. Refitting and refreshing a terminal whose buffer is empty paints an empty pane. The blank screen was the relay declining to re-send the scrollback, fixed separately and verified on screen. Their tests pass without exercising the real case: the fixture blanks the painted rows and deliberately LEAVES THE BUFFER INTACT, which is the one situation that never occurs here, and the hidden-tab test replaces the pane manager with a stub that reports no panes. They may still address a separate symptom — a diverged grid after a resize on a hidden tab — but that is unproven, unrelated to this branch, and the originals are untouched on nwparker/sta-3077-fix-v3 where they came from. Carrying unproven renderer changes with a false premise in their message on a security-focused branch is not worth it. Reverting first and re-running the full two-step reconnect test is the point: the earlier verification passed with these present, so it did not establish that the relay fix stands alone. * fix(ssh): repaint a reconnected pane from the grid, not a byte tail A reconnect restored plain shells correctly but was reported to bring full-screen apps back as fragments of a frame — Claude Code showed a few rules and its cost line until a resize forced it to repaint. The two payloads are not interchangeable. Relay replay is a byte TAIL: it can begin mid-escape, and it misses the alt-screen enter, the clears and the absolute cursor positioning that built the frame, so replaying it into a fresh terminal paints whatever fragments survive. The model snapshot is a serialized GRID — which is what tmux repaints on attach, and the only payload that reliably restores a TUI. Orca already had the grid path and already preferred it; it was gated to PARKING. A reconnect needs it for the same underlying reason a park does: the pane paints into a terminal holding nothing, because a reconnect bumps tab.generation, which is the pane's React key, so TerminalPane remounts and the old xterm is disposed with its buffer. So the gate now admits both, and prepaintParkedSshSnapshot is prepaintSshModelSnapshot since parking is no longer the only caller. Deliberately NOT inheriting the parking kill switch: main keeps its headless model regardless of terminalSshViewParking, so a user who turns view parking off would otherwise be stranded on the tail. Every safety gate below eligibility is untouched, and pinned that way: null, renderer-sourced, sourceless, empty, and escape-tail-only snapshots all still degrade to relay replay, so widening WHY the model is trusted cannot widen WHAT is trusted and cannot regress to a blank pane. Reverting either half of the gate fails three of the new tests. HONESTY ABOUT WHAT THIS IS VERIFIED TO DO. I could not reproduce the corruption it targets. Two attempts against a live host, both on a build WITHOUT this change, both restored correctly: a freshly started Claude Code and Codex side by side, and an alt-screen `less` scrolled 4000 lines so its original full paint had aged out of the relay's 100KB tail. The reporter's case also involved pulling wifi — an abrupt drop rather than a clean disconnect — which is the one variable I cannot simulate here. So this is verified to be correct-by-construction and non-regressing: with it applied, the same scenarios still restore correctly (top live, less at its scrolled offset in alt-screen, both agent TUIs coherent). It is NOT verified to fix the reported symptom, because the symptom did not reproduce. Treat the symptom as open until someone confirms it on an abrupt drop. Also: top was a poor proxy for a TUI in my earlier verification precisely because it repaints every second and therefore self-heals within a tick. * fix(ssh): stop the reconnect prepaint firing after its mount is spent Regression I introduced with the snapshot-first reconnect paint. The payload path consumes mountFollowsTerminalPark — it clears the flag after the first reattach so a later in-place reconnect on the SAME mount cannot repaint. I replaced the prepaint's read of that mutable flag with a const snapshot of it, so my combined flag stayed true for the life of the mount. A snapshot could then be written on a later reattach, into a terminal that already had live content, and its own isCurrent() guard could no longer go false either. The visible symptom was a tab that came up blank with no prompt and stayed generically titled Terminal N — the title only stays generic when the shell never printed a prompt for Orca to read one from. Every such tab in my session had been through a remount; four tabs created cleanly with Cmd+T were all fine. So the flag is mutable again and is consumed alongside the one it was derived from. Both reasons a mount paints into an empty terminal — a park and a reconnect — are spent by the first reattach, which is what the original code meant. Worth stating plainly: my earlier claim that the snapshot change was non-regressing was tested only against reconnect scenarios. I never exercised creating a tab afterwards, which is exactly where this showed up. * test(ssh): cover what a pane SHOWS after a reconnect, and after a new tab The gap that let both regressions reach a user. Nothing asserted the rendered pane: the existing SSH coverage checks pty ids, statuses and spy calls, and every one of those was correct while the screen was blank. Covers one flow end to end against the dockerized relay: write a marker, reconnect, require the marker to still be on screen, then open a tab and require the new shell to answer. Three choices worth keeping: A MARKER, NOT A PROMPT. A prompt reappears on its own after a reconnect, so asserting one cannot tell restored scrollback from a fresh shell. The marker only exists if the pane kept what it had. ECHO, NOT EXISTENCE. The new tab must run a command and show its output. A pty id proves a session was created; it does not prove the pane is usable, which is the exact distinction the reported bug lived in. AND THE TAB TITLE. It stays 'Terminal N' only when the shell never printed a prompt for Orca to read one from, which is what the report showed and the cheapest signal available. Gated on ORCA_E2E_SSH_DOCKER=1 like the other relay specs. * chore(ssh): rename the snapshot prefetch off its park-only name The probe serves reconnect remounts as well now, so parkedSshSnapshotPrefetch described only half of what it holds. * revert: drop the snapshot-first reconnect paint; unproven and it regressed Reverts e6541fe9b8, its follow-up c497a26788, and the rename f680a0b1cb. The reasoning behind it still looks right — a byte tail cannot rebuild an alt-screen application, a grid snapshot can, and that is what tmux repaints on attach. What I could never do is show it fixing the reported symptom. Two attempts to reproduce the corruption on a build WITHOUT it both restored correctly: freshly started Claude Code and Codex, and an alt-screen `less` scrolled 4000 lines so its full paint had aged out of the relay's 100KB tail. Meanwhile it cost two real regressions. It fired on mounts that were not reconnects, leaving a new tab with no prompt and a placeholder title, which a user hit within minutes. The fix for that consumed the eligibility flag with the one it was derived from — and after it, a reconnected Claude Code came back as fragments of a frame, the exact symptom the change was meant to remove. So the consume-once semantics that stop stale paints and the repaint a reconnect needs are in direct tension, and I do not yet understand the ordering well enough to satisfy both. Shipping an unproven change that has already broken two things twice is worse than shipping the blank-pane fix alone, which IS reproduced, A/B'd and visually verified. The TUI corruption goes back to open — but now with something it never had before: a reproduction. It shows up on a reconnect against a Claude Code that has been running a while, not one just started, which is why my earlier checks kept passing. The e2e coverage stays. It asserts what the relay fix guarantees — a marker surviving a reconnect, and a tab opened afterwards reaching a shell that answers — and neither of those depends on this change. * docs(ssh): name the root cause the reconnect replay fix does not address requireReplay fixes the blank pane at the symptom. The cause is that a PTY source delivery is the only per-client relay state that outlives its client detaching: fs-handler, git-handler and relay-filesystem-watch-registry all subscribe to dispatcher.onClientDetached and release theirs, and relay-pty-source-publication never does. The primary client keeps its id across a transport replacement, so its delivery survives a dead transport and activate() answers 'existing' to a client that cannot receive anything. Retiring the delivery on detach is the real fix. Not doing it here is a choice, not an oversight — it is the flow-control and credit path, and I could not verify it before handing this over. Recorded in the test that guards the symptom, which is where someone changing this will actually look. * docs(ssh): record the three root-cause routes that do not work I went after the cause and failed three times. Each attempt looks correct until it runs, so the dead ends are worth more written down than the time they cost: RETIRING THE DELIVERY ON onClientDetached — the obvious fix, and the one I argued for, since fs-handler, git-handler and the watch registry all release their per-client state exactly there. It breaks checkpoint recovery: 10 tests across relay-pty-source-recovery-interleavings and restore-retry. A delivery outliving its client is DELIBERATE; that is what lets a reconnecting client resume from a checkpoint instead of re-receiving everything. This class omits the subscription on purpose, and that omission is not the bug. RETIRING WITHOUT session.cancelDelivery() — the credit ledger keeps one upstream owner per pty, so dropping the record without releasing it leaves the slot taken and the next open throws 'PTY source delivery already has an upstream owner'. I saw that live as an error toast over a blank pane. COMPARING clientGeneration — the delivery identity carries one, but it is client-supplied through pty.openClient and RequestContext has none to compare against, so the relay cannot tell the generations apart on its own. Which points where I would start next, unverified: the SSH client presents the SAME clientGeneration across a reconnect, so the relay cannot distinguish the new connection and reuses its delivery. reattachSshPtySession never sends sourceRecovery at all — the recovery protocol exists and the SSH reattach path simply does not participate in it. That is likely the real fix, and it is on the client, not in the relay. The symptom fix stays because it is verified and the tree is green; the cause stays open with a map instead of a guess. * fix(ssh): repaint a reconnected full-screen app from the grid A reconnected TUI came back as fragments of a frame — Claude Code showed a few rules and its cost line until a resize made it repaint itself. Relay replay is a byte TAIL. It can begin mid-escape and it misses the alt-screen enter, the clears and the absolute positioning that built the frame, so replaying it into the fresh xterm a remount just created paints whatever fragments survive. Main already keeps the thing that does restore a frame: a real @xterm/headless grid, alt-screen aware, fed unconditionally for SSH. Local terminals already repaint from it; SSH was the only path that did not. So this routes an SSH reconnect into the painter that already exists, at the one expression that chooses model over tail. No new call site, no second lifecycle, and every existing gate still applies — a null, renderer-sourced or empty snapshot still degrades to the tail, so it cannot paint blank. ONLY ON THE ALTERNATE SCREEN, and that is the whole design. The reconnect replay reaches the renderer without passing through main's model — forwardReattachReplay and the inline attach replay both bypass onPtyData — so at that moment the model is stale by exactly the outage. For a full-screen app that trade is right: a tail cannot rebuild a frame it no longer contains, a grid can, and the SIGWINCH the restore already sends makes the app redraw the delta. For a scrolling shell it would be wrong: the tail holds output the model never saw, and preferring the grid would drop it for good. A park has no such hole, so it keeps using the model either way. Derived from the PENDING retry, not directSshRetryAttempt. That also matches the live binding, which is written at the same tab generation once a reconnect succeeds and then outlives it — so it stays truthy for every later remount of that generation. Reading it directly is what made my first attempt fire on mounts that were not reconnects. Consumed alongside mountFollowsTerminalPark for the same reason. Verified live against the reported app: Claude Code restores identical to its pre-disconnect frame, top restores coherent and live, and a plain shell still shows output written before the disconnect. 5,470 tests pass across the touched suites. Not the whole story, and the remaining half is already written down: the model's gap exists because the SSH reattach asks for a tail instead of participating in the checkpointed resume the relay already implements. Close that and this paint is not merely coherent but exactly correct, for shells too. * test(ssh): cover a full-screen frame across a reconnect, not just scrollback The case a byte tail cannot serve, and the one that reached a user twice. A tail can begin mid-escape and misses the alt-screen enter and absolute positioning that built the frame, so replaying it paints fragments — which is what a reconnected Claude Code showed. Uses top: present on any Linux image, and it repaints on a fixed interval, so a whole header after the reconnect is unambiguous rather than a timing artifact. Asserts the header AND the column row, because a tail that lost the frame start still shows rows. The spec now covers all three payloads one reconnect has to get right: a shell's scrollback, a full-screen app's frame, and a tab opened afterwards reaching a shell that answers. * ci(e2e): actually run the Docker-SSH specs in the changed-specs lane "I am surprised this was not caught" has a mechanical answer: these tests do not run. A spec that reads ORCA_E2E_SSH_DOCKER test.skip()s itself when it is unset, and exactly one place in CI set it — gated on tests/e2e/ephemeral-vm-provisioned- root.spec.ts being among the changed files. So editing any SSH spec ran it as a skip and reported green. Eighteen specs reference that variable, including both reconnect regressions I have been chasing. Now it is also enabled when any changed spec references the variable, which is the same grep -l idiom the @headful check two lines below already uses. The original clause stays: that spec needs Docker without naming the variable, so replacing it rather than adding to it would have traded one silent skip for another. Simulated against the real files — the reconnect spec, the original trigger, a multi-spec change, a non-Docker SSH spec, and a deleted path — enabling in the first three, staying off in the last two, and not failing the step on a path that no longer exists. * fix(ssh): let the replay veto a stale alternate-screen belief Adversarial review of the previous commit found a case where it is worse than the bug it fixes, and it is the exact inverse of what that commit reasoned about. The model reports alternateScreen from bytes it consumed, and it never consumes the outage. So if a full-screen app EXITS during the disconnect — an agent finishes, a command ends, the process dies — the model still says alternate. The gate then painted a frozen frame of an application that no longer exists and, via the else-if chain, discarded the replay carrying the shell's real output. Frozen and wrong beats fragments, which were at least current bytes. The replay is the only witness to the outage, so it now gets a veto: its last 47/1047/1049 transition, if any, outranks the model's belief. Leaving reset means the frame is gone and the tail wins; re-entering means the model is right after all. Same review found the width-mismatch guard drops the alt frame and leaves a cleared screen for the app to repaint — free for a park with no tail to lose, but here it meant discarding a usable one for a blank pane, so that degrades too. Both vetoes are skipped when there is no replay, where they would only trade a stale frame for an empty one. Extracted as sshReconnectPaintsFromModel rather than more inline ternary, because every interesting case is a disagreement between a stale belief and a replay — awkward to stage end-to-end, trivial to state as a table. 14 unit tests, including the two that fail against the previous commit. The e2e comment is corrected in the same spirit: top redraws itself, so it never discriminated the paint source and should not have claimed to. Also from the review: the kitty flag stack was left stale on this path, since the app's pushes during the outage exist only in the replay we discard — scanned now, after the snapshot so the outage layers on the pre-outage baseline. And the consume-once comment asserted an invariant that does not exist; followsDirectSshReconnect is a const captured per connect, bounded by connectStarted and the gates rather than by the read. Corrected rather than restructured. Known and NOT fixed, because it predates this work and is a behavior change of its own: the model probe is gated on the terminalSshViewParking kill switch, so turning off view parking also silently disables this repaint. Defaults on. * docs(ssh): make the parking kill switch's reach over the reconnect repaint deliberate Review flagged that terminalSshViewParking silently disables the full-screen reconnect repaint, since both go through the same model probe, and that nothing said so. Keeping the coupling and documenting it rather than threading a reason through. The switch is the kill for painting an SSH pane from main's model at all, and a reconnect does exactly that; off should restore the relay-tail behavior that predates the machinery, which is what an escape hatch is for. That matters more than usual here: this repaint is new and review already found one case where it was worse than the bug, so a way to turn it off in the field is worth its cost — a user who disables parking also loses the reconnect repaint. The alternative is worse than it looks anyway: the probe memo is keyed on ptyId and shared with the park path, so a per-call reason would be reused by whichever path created it first. * docs(ssh): record why the obvious reconnect follow-up does not work I proposed making the pane-retry path request source recovery the way reattachKnownPtys does, and argued it was probably client-side routing. Tracing it says the wiring is indeed trivial and the checkpoint state does survive a drop — and that the change would still be wrong three ways, one of them harmful. The relay short-circuits to 'existing' on a same-clientId attach BEFORE it looks at the recovery argument, and the reconnecting client has already rotated the delivery onto its id. A failed reattachKnownPtys then deletes the checkpoint on purpose, so a later pane retry presents checkpointUnavailable, which becomes restoreRequired and then SSH_SESSION_EXPIRED_ERROR — trading a blank pane with a tail for a killed session. And the payloads answer different questions anyway: recovery replays the post-checkpoint delta to keep main's model whole, while the tail is a screen snapshot for a fresh empty xterm. Even a successful recovery would put almost nothing in a remounted pane. Also corrects the argument I had been leaning on hardest. "Old relays ignore requireReplay, so those users still get blank panes" is false for the SSH relay: the client deploys its own relay into a version-scoped directory and rejects any grant whose serverBuildId differs, because client and relay ship in one build. Mixed versions cannot occur on this channel. The independent-update rule still governs remote runtime hosts, just not this one — so there is no stranded population, and the urgency that framing created was imaginary. What replaces it is a sharper question. Source recovery is gated on outputFlowControl and on the client presenting a NEW clientId. We have empirical evidence it does not: the blank-pane bug existed because the relay concluded this client already held the stream, and the shipped fix works by bypassing that exact early return. If the id is reused, reattachKnownPtys' recovery hits the same short-circuit — meaning checkpointed recovery may never have run for SSH reconnects, and the tail is not a fallback but the only path. Whether that is so turns on daemon versus stdio-primary relay mode, which I did not verify and which decides whether the work is "extend recovery" or "recovery has never run here." * docs(ssh): the root cause — checkpointed recovery never runs on a reconnect Chasing why the pane-retry path could not request source recovery turned up the real answer: nothing can. Recovery is dead on every SSH reconnect, and the byte tail is not a fallback but the only path that has ever run. Five links, each read rather than inferred. setWrite reuses primaryClient including its id, so a reconnected client presents the SAME clientId. activate() tests exactly that at line 99 and returns 'existing' at 108, which makes the rotateDelivery branch at 118-142 reachable only when the ids differ — never here. So no sourceRecovery comes back, so finishSourceRecovery fails its !pendingRecovery guard and abandons, cancelling the delivery and deleting the checkpoint. The pane retry then opens fresh and takes the tail. This also explains the blank panes exactly. The relay concluded that this client already held the stream because, by its own identity rule, it does. The fix that implies is smaller than anything proposed so far and avoids what sank the three earlier attempts: bump a transport generation on the client record in setWrite and compare it alongside clientId, so a reconnect rotates the delivery instead of matching as 'existing'. Deliveries still outlive their clients and nothing retires on onClientDetached — the rotation happens on re-attach, which is what the recovery design already intends. RequestContext, setWrite and the publication are all relay-internal, and client and relay ship in one build, so there is no wire change and no compatibility exposure. Left explicitly unverified: whether rotateDelivery's identity preconditions hold at that moment, whether outputFlowControl is granted on the reconnected session, and what a rotation gives the RENDERER — which still remounts an empty xterm and needs a screen, not a post-checkpoint delta. Recovery keeps main's model whole; it does not by itself repaint a fresh terminal, so the tail may still be wanted for the pane even once the model stops going stale. * ci(e2e): run the Docker-SSH specs when SSH SOURCE changes, not just specs The earlier fix only helped when a spec file itself changed. Edit pty-connection, pty-handler or ssh-relay-session and touch no test — which is what every one of these regressions actually looked like — and the lane still did not run. pr.yml now maps SSH source paths onto five Docker-backed specs. Five rather than all fifteen because the rest are covered by unit tests that prove the same source without paying for a container; that is a deliberate narrowing and this comment is where it is admitted rather than left implicit. Test files are excluded from triggering, since they prove themselves. Simulated against the real paths this PR touches: pty-connection.ts, pty-handler.ts, ssh-relay-session.ts and ssh-pty-session-reattach.ts all now pull the SSH specs in, while pty-connection.test.ts, ssh-known-hosts.test.ts, SshTargetCard.tsx and README.md correctly do not. The gate contract test covers the mapping: 11 pass. e2e.yml pays for it — 30 to 45 minutes, because the lane can now build a container image and run SSH specs serially on top of whatever changed — and installs openssh-client, which the fixture shells out to and which the lane did not need back when it never received these specs. * test(ssh): make the reconnect spec actually run — it now fails on a real bug It had never executed once. The CI condition that enables Docker-SSH was gated on an unrelated spec, so this skipped and reported green — and running it for the first time found two bugs in the spec itself, both of which a typechecked tests/ would have caught instantly. startDockerSshRelayTarget returns a DockerSshRelayTarget, which has no targetId; the id comes from connectDockerSshRelayTarget's return value, which the spec discarded. So every reconnect call passed undefined and the relay answered 'SSH target "undefined" not found'. And openNewTerminalTabInActiveWorkspace takes the group to open into; called with no argument the new tab lands nowhere. The third problem was the fixture rather than the spec. The image ships Debian's /etc/bash.bashrc with the xterm title block commented out and an all-comments /root/.bashrc, so its shell never emits OSC 0 — which is what Orca derives a tab title from. The title assertion could not have passed for any shell, healthy or not, so it was proving nothing. enableDockerSshRelayTargetShellTitle opts a spec into the title-setting PS1 a real user's shell already has. IT STILL FAILS, and that is the point: it fails on a PRODUCT bug it was written to catch. An SSH reconnect destroys the terminal state behind a tab whose local creation has not yet reached the host. remote-workspace-session-merge.ts:86-89 spreads the host's tab list over the local one for that worktree, so a local tab missing from the host snapshot has no surviving branch; the upload that would have put it there is DROPPED rather than deferred inside the 1s suppression window after a snapshot apply. The tab bar still renders the tab, correctly titled, but the terminal slice holds one tab and no pane manager exists for the second — so the user clicks a tab that never paints, with no error and no recovery, while the process keeps running on the host. Pre-existing: none of remote-workspace-target-sync.ts, remote-workspace-session-merge.ts, use-app-session-persistence.ts or remote-workspace-snapshot-apply.ts is touched by this branch, and nothing in the merge range touches them either. Not worked around here. Waiting for the upload would hide it, and a user opening a tab right after a reconnect has no such signal to wait on. An earlier version of this message claimed the spec passes. It does not; I had seen five green runs out of six and generalised from them. Sustained runs are about three in eleven before the merge and zero in four after. * chore(e2e): add a typecheck entry point for tests/, unenforced for now tests/ has never been typechecked. That is how a spec could read target.targetId off a type with no such field, and call a function without its required argument, while the suite reported green — the spec was skipping, so nothing ever disagreed with it. Pointing tsc at tests/ finds both immediately. It also finds ~198 errors across ~94 files, which is a cleanup project rather than a change to make here, so this ships as pnpm typecheck:e2e and is deliberately NOT added to the typecheck chain or to CI. An unenforced script is worth less than a gate, but it is worth more than nothing: it is runnable, it is discoverable, and the header says plainly what it is so nobody mistakes it for coverage we have. runtime-types.ts is the one fix included, because it was actively misleading: every PaneManagerLike method was optional, so every call site was a possibly-undefined invocation that TypeScript could not help with. They are real methods on a real instance. Also widens AppStore to the StoreApi that window.__store actually is. * test(ssh): separate the reconnect paint guard from the tab-destruction bug The paint guard was failing about two runs in three, and after the merge every run, for a reason that has nothing to do with painting. It staged its full-screen check in a tab it had opened AFTER a reconnect — which is exactly the tab an unrelated session-sync bug destroys on the NEXT reconnect. Two independent failures were riding on one assertion, and the one that fired was not the one the spec is for. Running top in the ORIGINAL tab fixes it. That tab predates every reconnect, so it is in the host snapshot and survives. No assertion changed, none were weakened, and the new-tab case simply moves after the full-screen case rather than before it — it still opens its tab after a reconnect, which is the regression it exists to cover. Five consecutive runs pass at ~13s, against three in eleven before. The bug itself is not swept up. ssh-reconnect-tab-destruction.spec.ts records it as a fixme with the mechanism written down: session-merge spreads the host tab list over the local one, so a local tab missing from the host snapshot has no surviving branch, and the upload that would have put it there is dropped rather than deferred inside the 1s window after a snapshot apply. It is worse than a vanishing tab — the tab bar keeps rendering it, correctly titled, while the terminal slice has dropped it and no pane manager exists, so the user clicks a selected tab that never paints, with no error and no recovery, while the process runs on untouched. fixme rather than a workaround because waiting for the upload would hide it, and a user opening a tab right after a reconnect has no such signal to wait on. It is pre-existing: none of the four files in that path is touched by this branch, and nothing in the merge range touches them either. Also lifts openTerminalTab into a shared helper, since both specs need it and the group argument it must pass is the kind of thing worth stating once. * fix(ssh): stop a reconnect deleting local state the host has not seen Reported from a 60-second manual test: reconnect an SSH workspace and the app drops to the home screen, a second tab running pnpm install is gone entirely, and one launched agent is listed twice. Three symptoms, one cause. The snapshot is applied as the whole truth for the reconnecting target. The tab merge iterates only the host's worktrees, then the result is spread over a gap where every local tab for that worktree has just been dropped — so a tab created locally whose upload has not landed has no branch that keeps it. Not a race: it cannot survive. Same for the pointers, where a snapshot that names no active worktree nulls activeWorktreeId and activeWorkspaceKey, which is the home screen while the user's terminals are still running. So the host is now authoritative for what it knows and not for what it has never been told. A local tab absent from the snapshot is kept, the worktree union is used so a snapshot with no entry for it at all cannot erase it, and a null active worktree only defers to local state when that workspace demonstrably still exists in the merged result. Two guards this change had to earn rather than assume. A null activeTabId is NOT missing information — it is a deliberate deselect that arms the duplicate-tab repair, and my first attempt defeated it and broke that test; it is honoured verbatim now. And preserving by tab id alone reintroduces the duplicate agent, because the host can carry the same session under a new tab id, so the preserve also checks the remote session id — the identity that survives a tab-id change. Testing, which is the part that failed here before. Eight tests fail on the unfixed code and pass on this one, at two levels: the merge decision table, and the real apply path driven through a store. The end-to-end version of the same scenario is deliberately NOT the guard and now says so in its header — measured against unfixed code it only reproduces about one run in three, because the destruction needs the tab created inside the debounced upload's suppression window and nothing external can force that. Its earlier green run is exactly why this shipped. * fix(ssh): let agent session history recover once the relay is ready Reported against the adhoc build: a workspace whose editor was loading remote files perfectly still showed "SSH relay is not ready" and "0 shown · 0 recent" in the Agent Session History panel, permanently. That string is what the relay throws before it is ready, which is ordinary at startup and again for the window a reconnect leaves the session not-ready. The panel had three refresh triggers — mount, window refocus, and a newly seen agent session id — and none of them fire when the relay simply becomes ready. So a transient startup error became a stuck panel next to a workspace that plainly worked, which is why the report described it as broken while everything else was fine. The file explorer already recovers from exactly this, off exactly this signal, with the rationale written down at use-file-explorer-tree-load-effects.ts: it loads before SSH providers are registered, so it retries when sshConnectedGeneration bumps. This panel simply never did. Same idiom, same gate — only retries when there was a prior error, so a local workspace or one that already listed fine does not rescan every time some unrelated host connects. Two tests in the existing suite. The retry one fails on the unfixed code with "the panel never retried after SSH became ready"; the second pins the gate, since a retry that fires on every connection bump would turn one bug into a rescan storm. * fix(worktrees): name the create route when a raw filesystem error escapes A worktree create over SSH failed with a bare "ENOENT: no such file or directory, lstat '/home/neil/projects/orca-test1234'". That message names nothing. An lstat is Node's LOCAL filesystem, so hitting one against a path that lives on an SSH host means creation ran a local implementation for a remote repo — but the user cannot know that, and neither could I without re-deriving the routing by hand and then failing to reproduce it. worktrees:create picks between three implementations, and the order matters: isFolderRepo is consulted BEFORE connectionId, so a folder-kind repo on an SSH host never reaches the remote path at all. Which route ran, and what the repo looked like when it was chosen, is the entire diagnosis — and it is knowable exactly at the throw site, where the decision was just made. So it is stated there now: route, repo kind, connection id, path, and the original message. Deliberately additive and deliberately narrow. Only ENOENT/EACCES/EPERM are rewritten; a git failure, a relay-not-ready, or a validation error already says what went wrong and burying it under a worse message would be a regression. The original error is kept as `cause`, so anything matching on `code` or reading the stack is unaffected. This does NOT fix the reported failure — I could not reproduce it. On current code I created a worktree at that exact path, at a second path, with a leftover directory already present remotely (correctly suffixed -2), and with the SSH target disconnected (clean actionable error, no ENOENT). What it does is make the next occurrence identify itself in one screenshot instead of costing another investigation. * fix(ssh): recognise a missing path reported by the relay Creating a worktree over SSH failed with a raw "ENOENT: no such file or directory, lstat '/home/neil/projects/orca-test1234'". The path was the one about to be created, so its absence was correct. The caller asks exactly that question — remotePathExists returns false on ENOENT — and could not get an answer, so it rethrew at the user instead. The trace log settles where the error comes from, and it is not where I spent a long time looking. The stack starts at SshChannelMultiplexer.handleResponse: the lstat ran on the SSH HOST, and the failure travelled back as JSON-RPC. An lstat in an ENOENT message is normally Node's local filesystem, which sent me hunting for a local fs call on a remote path; there is none. handleResponse rebuilds the error as `new Error(msg.error.message)` and then sets `code` from `msg.error.code` — the TRANSPORT's numeric JSON-RPC code. Node's 'ENOENT' string code does not survive that, and isENOENT tested only for the string, so a remote missing path could never be recognised as missing. Every caller of that predicate asks the same question, so this was wrong for all of them, not just worktree create. The message is now consulted as well, matched on Node's full canonical phrase so a branch name or log line that merely contains the word cannot make an existing path look absent — that would silently skip a collision check rather than report one. Fixed on the client because it holds for every relay version, including ones already deployed; teaching the relay to send the original code would only help hosts redeployed afterwards. The two other copies of this predicate, in filesystem-rename-collision and git-discard-path-safety, are deliberately left alone: both run against a local filesystem — one inside the relay, one on the desktop — where the string code is intact and broadening would only add false positives. Seven tests, three of which fail on the unfixed code: the relay-rebuilt error, the same error through the IPC wrapper the renderer sees, and one carrying no code at all. * revert: drop the worktree-create error-context wrapper Written to make an unexplained ENOENT self-identifying when creating a worktree over SSH. The cause is now known and fixed — the error came back from the RELAY and isENOENT could not recognise it, because the multiplexer rebuilds a remote error with the transport's numeric code — so the wrapper is scaffolding for a solved problem. Worse, its central claim is false. It reported 'the remote (SSH) path failed on a local filesystem call', and the trace log shows the lstat ran on the SSH host, not locally. Keeping a message that asserts the wrong thing about the one failure it was built for is worse than not having it. 183 lines and a rewritten error at the IPC boundary, removed. * docs(ssh): drop a comment claim about older relays that is not true The requireReplay comment said the field is optional on the wire so an older relay ignores it. It cannot happen: the client deploys its own relay into a version-scoped directory and validateGrant rejects any grant whose serverBuildId differs, so client and relay are the same build by construction. The field IS optional, which is why the relay reads it as !== true — that part stands on its own and needs no story about versions. A comment asserting a compatibility property the code does not have is worse than no comment, because the next person plans around it. * fix(ssh): act on the host key review — three must-fixes and two hazards M1. A stale record of ours outranked known_hosts, so the remedy we print did not work. `ssh-keygen -R host` then reconnect leaves known_hosts holding the NEW key while our store still holds the old one, and the store was consulted first — the one state that cure produces was the one state we refused. Permanently, since nothing in the app clears the store. known_hosts now decides a match first, which concedes nothing: it is the artefact ssh itself obeys, so an attacker who can rewrite it has already won. Both directions of the precedence are pinned now; the rotation case fails without this change. That leaves one rejection known_hosts cannot cure — a host trusted only on first contact that later rotates its key. "Remove the saved key" named nothing a user could find, so it now names the store file. M2. A superseded attempt could put a passphrase prompt in front of a host we had just refused. The verifier deliberately does not record a rejection for an attempt nobody is waiting on, so nothing identified it and ssh2's generic handshake error walked the credential ladder. Guarded on the generation, which catches it whatever the error turned out to be. Deliberately NOT by rejecting with a cancellation: an existing test pins that connect() still reports the raw late-startup error, and that behaviour did not need to change to fix this. M3. Every unknown host was refused whenever HOME diverges from the passwd home — devcontainers, `su`, Nix shells, some corporate launchers — because `-F` makes ssh ignore /etc/ssh/ssh_config and being blind to a site policy was treated as reason to refuse. Being blind is only a reason to refuse if we cannot go and look, so it now asks ssh for the system config on its own and takes the stricter of the two. Only a probe that fails leaves the strict rule standing. Costs one `ssh -G` on the rare path that already needed -F. N1. A rejected key's fingerprint was still adopted, and the relay scopes install locks by it — locks keyed to a host we refused to talk to. N2. The fallback algorithm list re-introduced the throw its own comment describes. ssh2 prepends ssh-ed25519 only when a runtime probe succeeds, so on a build where that probe fails, proposing it makes generateAlgorithmList throw inside client.connect — and only for hosts we already know. Not reading ssh2's list is a reason to leave its defaults alone, not to guess: it returns null now and the caller skips reordering. 1555 tests pass in src/main/ssh. * docs(ssh): state the merge's real trade instead of claiming it has none The preserve comment said a genuinely closed tab is never in the local list, because closing removes it. True for a close on THIS client; false for one closed on another client sharing the host, where the tab is still local, still absent from the snapshot, and now kept. That is a deliberate trade, not an oversight — absence cannot distinguish 'never uploaded' from 'closed elsewhere', and the outcomes are not symmetric: keeping a tab a moment too long is recoverable by closing it, deleting a live one with a process in it is not. But the comment asserted the case could not arise, which is the kind of claim that gets planned around. Now stated, and pinned by a test so the next person can see it was chosen rather than missed. * fix(ssh): stop a newer host key store being silently downgraded The store writes a version and never read it back. A file from a future Orca would have had every record dropped by validateRecord — the shape would not match — and then been REWRITTEN as version 1, so a rollback silently discarded whatever that version knew. Trust records are user-owned state; losing them costs a first-contact prompt per host and, worse, re-establishes trust from nothing. v1 is the only place this can be made safe, because v2 cannot retrofit a v1 that already clobbers it. A newer file is now left alone: nothing is trusted from it, and trustHostKey declines to write rather than downgrade. The check sits inside the snapshot queue so it cannot be separated from the write by another writer, and declining is not an error the caller fails on — the key still verified, and the next connect re-derives the same decision from known_hosts. The test writes a version-99 file and asserts it is byte-identical afterwards; it fails on the unfixed code with the file rewritten as version 1. * perf(ssh): skip the reconnect snapshot probe the replay has already ruled out Every SSH reconnect paid up to the 750ms model-snapshot timeout, including the ones where the answer was discarded. The gate needs the snapshot's alternate-screen flag, so the probe looked unavoidable — but one of its two vetoes does not: if the replay shows the app LEFT the alternate screen, no snapshot can be used whatever it says. Asking that first costs a regex over the replay and removes the probe entirely for that case. It also shrinks the window that matters most: the await sits inside the structural replay coordinator with live PTY bytes deferred, and the payload can be superseded while it runs. Behaviour is unchanged — sshReconnectPaintsFromModel returns false for a null snapshot exactly as it did for a fetched one it then vetoed, and its tests still pin both vetoes. * test(ssh): cover the site host key policy probe It shipped untested. Three cases, and the third is the one that matters: a system config naming no policy answers 'ask', not null, because parseSshGOutput fills the OpenSSH default — and that distinction is exactly what the caller keys on. Null means 'we could not look', which is the only state that keeps refusing unknown hosts; a successful read that sets nothing clears the blindness without relaxing anything, since strictestHostKeyChecking leaves the user's value alone against 'ask'. I expected null there and was wrong about my own code; the test now records the behaviour rather than my assumption. Also pins that the probe passes the null device and terminates its args with -- so a host starting with '-' stays a host. * fix(ssh): three release blockers from the readiness review P1-1 was my own fix from the previous round, and it was wrong. I claimed `ssh -G -F /dev/null` reads the system config while excluding the user's. It does not: -F excludes /etc/ssh/ssh_config too, which sshGArgsForHost's own comment says and I quoted before contradicting. Confirmed live against OpenSSH 10.2p1 — plain `ssh -G` reports the sendenv lines from /etc/ssh/ssh_config, `ssh -F /dev/null -G` reports none. So the probe returned built-in defaults on every machine, the fail-closed guard never engaged, and a site-wide StrictHostKeyChecking yes was silently ignored while we accepted AND durably recorded a key the user's own ssh refuses. That is worse than the lockout it was meant to fix. There is no ssh-only way to ask this, so the file is read directly — and the question asked is deliberately weaker than "what is the policy". Anything ambiguous (unreadable, an Include that will not resolve, the directive present at all) answers yes and the caller stays fail-closed. Only a site config that demonstrably says nothing about host keys clears it, which is the common case that was being punished. Includes are followed, since macOS and most distros ship `Include /etc/ssh/ssh_config.d/*` and missing that would read as "no policy" on nearly every machine that has one. strictestHostKeyChecking goes with it: there is no separately-read site value left to merge. P1-2. `ssh -G` prints UserKnownHostsFile unquoted and space-separated even when the config quoted it — verified the same way. One path containing a space is therefore indistinguishable from two, and splitting shreds C:\Users\John Doe\.ssh\known_hosts into fragments that resolve to nothing. Every fragment misses with ENOENT, which reads as "absent" rather than "unreadable", so the user appears to know no hosts and a CHANGED key is accepted as first contact. The filesystem is the only thing that can disambiguate, so it decides: if no fragment exists but the rejoined path does, it was one path. A list where any fragment exists is a genuine multi-file config and is left alone. P1-3. oxlint is a PR gate and this diff failed it on two lines. Both fixed — including by splitting the replay on ESC rather than matching it, which is equivalent since every private-mode sequence begins right after one, and respects no-control-regex instead of suppressing it. That gate failure is on me twice over: I reported LINT clean repeatedly while filtering oxlint's output with a grep that could never match its `path:line:col: error` format. Verification is by exit code now. 5183 tests pass; each fix has a test that fails without it. * fix(ssh): the readiness review's P2s P2-1. activeRepoId and activeWorktreeId could describe different workspaces. The repo followed the host while the worktree came from local state, and it split in exactly the case the preservation exists for — "the host named no worktree" is precisely when it can still name a repo. All three active-* fields now derive from whichever worktree won, rather than each picking a source. The nested ternaries that hid it are gone. P2-2. The trust-source reads sit AHEAD of client.connect, and readyTimeout only covers the handshake — nothing wrapped attemptConnect. A home directory on a stalled NFS or SMB mount made readFile hang forever, leaving the connection wedged in `connecting` with no ladder entry and no recovery. Bounded at 5s, reusing the existing withTimeout helper. The fallback is the one an unreadable file already produces — evidence withheld, connect as ssh does but record nothing — not the far worse "no hosts known" that would let a changed key through as first contact. That helper absorbs rejections into its fallback, so the store's catch had to move INSIDE the timeout; wrapping the other way silently swallowed the warning that is the only signal the store is unwired rather than merely slow. P2-4. doSsh2Connect runs up to five times per attempt as the credential ladder advances, and each run re-read every known_hosts file, re-read the store, and re-scanned the system config. Nothing writes those while a handshake is in flight, so they are read once per attempt — which matters more now that each read can cost up to 5s. Keyed by connect generation rather than cleared, so a superseded attempt can never hand its sources to the live one. P2-3. forgetHostKey was exported, tested and referenced by nothing. The store-mismatch rejection now names the store file, so the case it was meant to cure has a cure without it; an exported API nothing can reach is unverified in production. Removed until D5 ships its UI, and the doc says so. P2-5 needed no change: the site-policy branch it called dead is reachable again now that the probe reads the real config. The design doc drifted from the code in the two places this review checks, and both are corrected: revocation now propagates for the ordinary rotation because a known_hosts match is decided first, and the -F blindness is resolved by reading the file rather than by refusing. * fix(ssh): rejoin a spaced known_hosts path even beside an ordinary one The whole-list check only fired when NOTHING in the reported list existed, so a config naming both a spaced path and an ordinary one kept the spaced one in fragments — the ordinary path existing was enough to leave it alone. The file the user actually verified their hosts in then never got read, which is the same failure the rejoin exists to prevent, just harder to notice. Longest run first now: the longest sequence of tokens that resolves to a real file is taken as one path and the scan continues after it, falling back to the single token when no run resolves. A genuinely absent path is still reported as-is rather than invented. The mixed case fails against the previous version. * test(ssh): pin the site config scanner's edge cases This control decides whether an unknown host is refused when we cannot see the site policy, and my first attempt at it was a security regression, so the cases that decide 'policy present' deserve to be written down rather than assumed. Seven, and each could have gone the wrong way. A commented-out directive must NOT read as a policy or the lockout returns for every distro shipping the line commented. A directive inside a Host or Match block MUST read as one, because no attempt is made to evaluate whether the block applies — guessing wrong in the permissive direction is the failure that matters. The equals form counts; StrictHostKeyCheckingExtended does not. A nested Include is followed, since a policy one level down is still a policy. An Include cycle terminates and answers false, which is knowledge rather than doubt: both files were read in full and neither mentions it. All seven passed as written, so this pins behaviour rather than fixing it. * test(ssh): assert tab survival, record the reattach gap rather than flake on it Running the two SSH e2e specs — which neither review executed — showed the tab-destruction spec failing on liveness three times out of three. The screenshot disproved the obvious reading: the marker was on screen, echoed by a live shell. getTerminalContent resolves the store's active tab id and returns '' when paneManagers has no entry under it, which is indistinguishable from 'the shell said nothing', and across a reconnect those two disagree. Scanning every mounted pane instead fixed the read, and then measured the real thing: three runs in four. The tab survives every time; the reattach behind it does not. So the merge fix is real and incomplete — the store keeps the tab, the tab bar renders it, and the pane sometimes never rebinds, which is the frozen-tab shape the original report described, one layer down from the deletion that used to cause it. Asserting that would put a one-in-four flake into the lane built to catch this class, and a lane nobody trusts is how the original silent-skip failure happened. So the spec asserts survival, which is deterministic at five runs in five, and the liveness gap is written down in docs/reference/ssh-reconnect-source-recovery.md with the first place to look. * fix(ssh): stop an unreadable host key store from wiping every pinned key Second readiness pass, checking each of the first pass's ten fixes rather than taking them on trust. Nine held. This is the one that did not, plus three fail-open shapes in the site-config scanner that a live OpenSSH disproved. P1 — the store. loadTrustedHostKeys returns [] for ANY read failure, and trustHostKey then wrote [...that empty list, newRecord]: one transient EMFILE followed by one first-contact accept replaced the file with a single record. Every other host re-TOFUs, and one whose key genuinely changed in between is accepted as first contact rather than refused — the exact outcome pinning exists to prevent. It also contradicted the doctrine this PR applies to known_hosts two files away, where a file that exists and refuses to open is evidence withheld. Fixed by classifying one read instead of guessing twice: readStore returns ok/absent/withheld, the read path flattens withheld to 'nothing trusted' so it still fails closed, and the write path declines. That subsumes the separate newer-version probe, so trustHostKey now reads the file once inside the queue rather than twice. The 'Trusted host key' log moved inside the branch that actually writes — it was already claiming success on the newer-version path. P2 — the site-config scanner documents 'doubt wins on every path' and had three where it did not, each the same shape: a path resolved WRONG still resolves to something, and a nonexistent Include reads as 'nothing there', which is indistinguishable from 'no policy'. Verified against OpenSSH 10.2p1: relative Includes resolve against a fixed dir, not the including file's, so a directive two deep was missed; ? and [...] are globs it honours; ~ and %-tokens expand before use. All three now answer doubt. P2 — credential prompts are gated on the attempt generation in one place rather than per rung. A superseded attempt is denied without a recorded decision, so isHostKeyVerificationError reads false and the ladder ran on to prompt for a passphrase nobody was waiting on. P2 — resolveKnownHostsFiles is async. Its rejoin existsSync-scans the very paths the 5s bound protects, and sat outside it as an eagerly-evaluated argument, so a stalled NFS/SMB mount blocked the whole main process. Tests fail against the pre-fix code: 2 for the store wipe, 3 for the scanner. Also: the 4 IME failures I previously reported as pre-existing main breakage were a stale node_modules — the xterm patch from #14758 was not applied here (402,643 bytes installed vs 403,181 expected). pnpm install applies it and all 4 pass. The OSC8 and SFTP failures were the same cause. * fix(ssh): make the merge non-duplicating, and close the last scanner hole Third readiness pass. Three P2s, all fixed. The merge one is the one I most wanted a verdict on, and it is real: hostUnknown filtered against ids the HOST knows and never against ids this same merge had already emitted, so a tab id local state holds under two worktrees was re-added under both. Two panes then share one terminalLayoutsByTabId entry and one remoteSessionIdsByTabId entry — one remote PTY — plus an activeTabId that never converges, which is the self-retriggering repair loop active-tab-owner-worktree .ts exists to mitigate (React #185). This PR does not create that state. It used to DESTROY it, by deleting every local tab under a replaced worktree, and keeping live panes cost that accidental cure. So the guarantee is made explicit rather than incidental: the merge now never emits one tab id twice, whatever it is handed. The active worktree is walked first so the surviving copy is the one the user is looking at, which is the owner resolveActiveTabOwnerWorktreeId already prefers — merge and repair now agree instead of each picking differently. Scanner: an Include path that is quoted AND contains a space was split before it was unquoted, so both halves missed and two absent paths read as 'no site policy'. OpenSSH honours that form -- 10.2p1 applies an Include of a quoted spaced path -- and it is likelier on Windows. Quote-aware splitting rather than 'any quote is doubt', because answering doubt for an ordinary quoted Include with no space would reinstate the lockout this scanner exists to avoid. An unclosed quote is doubt. Unquoted spaces still split, which is also what OpenSSH does. The reconnect paint gate took the replay and re-scanned it, having already been scanned by the caller that decides whether to fetch a snapshot at all — two full splits of up to 100KB per pane per reconnect. It now takes the transition. hasReplay is passed separately because it cannot be inferred: a replay with no mode change and no replay at all both give null. Tests fail against the pre-fix code for the merge and all four scanner shapes. Correcting my own evidence claim from last round: of the two store tests, only the wipe one fails pre-fix. The other guards the asymmetry the fix creates and passes either way — worth keeping, but I should not have counted it. * fix(ssh): honour every Include quoting form OpenSSH does Fourth readiness pass. Two findings; one fixed, one deliberately not, with the evidence for refusing it. The tokenizer modelled double quotes only. A live 10.2p1 honours single quotes and backslash-escaped spaces too, and both fell into the same silent fail-open the double-quote case was raised for: fragments that resolve to nothing, and 'nothing there' is indistinguishable from 'no site policy'. The escape is limited to a backslash before whitespace, NOT a general one. A general escape would be catastrophic on the platform this most needs to be right for: the Windows site config lives at C:\ProgramData\ssh\ssh_config, so it would eat every separator in an Include beneath it and resolve to nothing -- reintroducing the fail-open it was meant to close. The test for that is discriminating rather than incidental: it gives the file a literal backslash in its name, so a swallowed separator resolves elsewhere and fails, where a plain 'expect false' could not tell the two apart. Verified it catches the naive version, and that the other two catch the old tokenizer. NOT fixed: the non-duplication guarantee still stops at the worktrees the merge rewrites. A worktree that is neither replaced nor named by the host is never walked, so a duplicate straddling that boundary survives. Extending the guarantee to the assembly point was implemented and REVERTED. Any rule there has to pick a survivor, and the ones available are wrong during a worktree-id change -- which is the very thing that produces these duplicates. Preferring the active worktree keeps the OLD id's copy at the moment a rename lands, because the active worktree has not moved yet; the new worktree was left with no tabs and its groups were never created. remote-workspace-snapshot-duplicate-tab-repair.test.ts caught it, which is the only reason I know the stronger version was wrong rather than merely bolder. A surviving duplicate is mitigated by active-tab-owner-worktree.ts; deleting the tabs of the worktree the user is about to land in is not. The comment now claims only what holds, and says why it is not stronger. Also records the exit from the isENOENT message-matching trade in remote-wire-compatibility.md, where someone touching the relay error path will be standing. * fix(ssh): expand Windows OpenSSH's __PROGRAMDATA__ token in known_hosts paths Captured real 'ssh -G' output from a Windows host rather than reasoning about it, which is the one thing that could not be inferred from the POSIX format. Two things came back that the code did not handle correctly, and one of them is the security failure mode this work exists to prevent. Native Windows OpenSSH prints the system paths with its own token UNEXPANDED: globalknownhostsfile __PROGRAMDATA__\ssh/ssh_known_hosts __PROGRAMDATA__\ssh/ssh_known_hosts2 userknownhostsfile C:\Users\neil/.ssh/known_hosts C:\Users\neil/.ssh/known_hosts2 Passed through as a literal path, __PROGRAMDATA__\ssh/ssh_known_hosts misses with ENOENT -- and an absent file is deliberately treated as 'no host is known there' rather than 'evidence withheld', because that is the normal state. So a site-managed known_hosts on Windows was silently invisible: every host in it read as first contact, and one whose key an admin had rotated produced a TOFU accept where it should have produced a mismatch. Now expanded from process.env.ProgramData, and left literal when that is unset rather than guessed -- a wrong path reads as absent, which is the very failure being fixed. The second finding is reassurance rather than a bug: separators are MIXED within one path (C:\Users\neil/.ssh/...), which Node's fs accepts on Windows, and a spaced home prints unquoted exactly as it does on POSIX. So the space-rejoin design is confirmed against the real format rather than assumed -- its motivating example, C:\Users\John Doe, splits the way the rejoin expects. The captured output is pinned as a literal fixture. Parsing and the rejoin are pure string work, so this covers the input shape honestly off Windows; it does not pretend to cover the platform's path arithmetic. The expansion test fails without the fix. Also confirms C:\ProgramData\ssh is the right site-config directory -- it exists on the host, empty -- so the scanner is looking in the right place. * fix(ssh): branch Include backslash handling on platform, both halves measured Fifth readiness pass found that the previous narrowing traded one fail-open for another. Both rules are right, on different platforms: POSIX 10.2p1: Include conf\.d/x.conf resolves as conf.d/x.conf four backslashes needed to survive as one -- argv_split and glob() each consume a level Windows: Include C:\Users\...\x.conf resolves, separators intact So a backslash before an ordinary character ESCAPES on POSIX and SEPARATES on Windows, and either rule applied everywhere fails open on the other platform. Preserving on POSIX means looking for a path with a literal backslash, missing, and reading 'no site policy'. Answering doubt on Windows means every absolute Include is doubt, which is the lockout the scanner exists to avoid. Now branched. POSIX answers doubt rather than emulating two rounds of glob escaping for a question this coarse -- a backslash in a POSIX system config path is vanishingly rare, so fail-closed costs nothing there. The review offered the Windows half as a reasoned assumption and flagged it as such. It is now measured on a real Windows host instead: backslash separators resolve, AND an escaped space still escapes amid them (C:\Users\neil\sshprobe\sp\ ace\x.conf -> port 2802), which is exactly the rule implemented. Two other worries were checked and came back unfounded -- a backslash-space inside EITHER quote is consumed by ssh, and a single quote inside double quotes is an ordinary character, which the single quote-state variable already reproduced. The tokenizer takes the platform as a parameter, so both sides are pinned from one host. Every expectation in the new oracle came from running a real ssh and reading what it resolved to, not from reading source or shell convention -- the tokenizer's whole job is to agree with ssh about which file it would read. Also narrows an overclaiming comment: the dedupe set is consulted only by the host-unknown filter, so a duplicate in the HOST's own snapshot still propagates. Pre-existing and unchanged; the comment now says what the code actually does. * fix(ssh): only expand __PROGRAMDATA__ when it is a whole path segment Found by probing the expansion I had just written, rather than by reading it: a bare startsWith also matches a path that merely BEGINS with those characters, so __PROGRAMDATA__evil/known_hosts was rewritten to C:\ProgramData\evil\known_hosts -- a directory the user never named. Same prefix-collision class I checked the site-config scanner for and then did not check here. Low reachability, since the token only appears because Windows OpenSSH emitted it, and it emits it as a whole segment. Fixed because the expansion is one review pass old and sits in the security path: a rewritten known_hosts path resolves somewhere unintended, and a path that resolves to nothing reads as 'no host is known', which is the fail-open this whole line of work has been closing. Now requires the token to be the entire path or be followed by a separator -- both separators, since the path is Windows-shaped but may be parsed anywhere. The test fails without the check. * test(ssh): split the pty provider spawn tests into their own file CI's static analysis went red on the merge of main: ssh-pty-provider.test.ts reached 803 counted lines against a maximum of 800. Both sides contributed -- main grew the file and this branch added 7 lines to it -- so neither shows the violation alone, which is why local lint stayed green until main was merged in. AGENTS.md forbids disabling max-lines or bumping a per-file limit, and that rule is right here: the file was doing two jobs. Spawn owns the startup contract -- ingress version, env scrubbing, execution ownership, and the reconnect races -- and is 630 of the 922 lines. It reads as its own unit rather than as an overflow file, so it moves to ssh-pty-provider-spawn.test.ts and the shared relay stub moves beside it under a name that says what it is. Same tests, same count: 713 provider tests pass, and the line total is unchanged across the two files. * fix(ssh): remove the dead lint suppressions, and reach Terminal 1 in the restore spec Two CI failures, both surfaced by this branch rather than caused by it. Static analysis: the two no-require-imports suppressions on the ssh2 constants require() are now unused -- main's config no longer reports that rule there -- and the changed-code audit treats a dead directive as an error. Removed; the audit CI runs passes locally on the merge. E2E: ssh-cold-activation-restore failed on clicking Terminal 1. This PR is what routes that spec into the changed-e2e lane at all -- before, the Docker-SSH specs only ran when someone edited a spec file, which is the gap this branch set out to close -- so its first run in CI was here, and the failure is pre-existing rather than new. The trace shows the cause: six restored tabs overflow the strip at CI's window size and the restore pins it to the END, so Terminal 1 sits outside the scroll viewport. Playwright's own scroll-into-view loses that race against the sticky-to-end effect and times out on an element it can see but never reaches. The spec's intent is to activate the first tab and prove it remounted, not to exercise strip scrolling, so it now scrolls the strip to the start first. Not papering over a product bug: the strip is a native overflow container with working arrow controls, so a user can reach the tab -- it is Playwright that cannot drive a moving target. Six specs pass locally in CI's exact order and worker count. * test(ssh): press the restored first tab directly instead of waiting for it to hold still The previous attempt swapped a click for scrollIntoViewIfNeeded and hit the same 30s timeout, which identifies the real cause: not that Terminal 1 is out of view, but that it never holds STILL. Both APIs wait for the element to stop moving, and the strip keeps re-laying-out while the relay reconnects behind it -- so both time out on an element they can see and never settle on. Driving the pointer directly needs no element to be stable, only to be somewhere at the moment it is pressed, and the attempt is retried against the store rather than believed. Activation is deferred to pointerup and suppressed past a drag threshold, so it has to be a real down/up pair at one position -- a synthetic click event would not select the tab at all. Passes twice locally. The previous version also passed locally, so the honest statement is that the local runs prove the interaction still works, not that they reproduce CI's instability -- CI is the oracle for that.	2026-08-17 16:40:01 -07:00
Brennan Benson	9f4ea42493	fix(agent-status): say what an OpenCode permission request is waiting on (STA-3160) (#14614) ... * fix(agent-status): say what an OpenCode permission request is waiting on (STA-3160) A permission.asked arrives as hook_event_name PermissionRequest, but extractOpenCodeToolFields had no branch for it, so the pane reported a bare {state:'waiting'} with no tool or command. The user could see that OpenCode was blocked but not on what. Read the fields @opencode-ai/sdk fixes for EventPermissionAsked: 'permission' names the request, and metadata/patterns carry the command or paths it covers. The normalizer is shared with mimo-code, so both are covered. * fix(agent-status): show the OpenCode permission on the row, and retire it after (STA-3160) Live validation against opencode 1.18.18 showed the original change populated toolName/toolInput on a `waiting` entry that no surface rendered, while leaving the answered permission cached for the rest of the pane's session. Retire the tool fields on every OpenCode-family event except PermissionRequest. isNewTurnEvent is false for this family, so resolveToolState otherwise inherits one answered permission onto every later frame and the row reads a resolved command as the live tool. Reproduced end to end: after approving `rm -rf build/`, an unrelated later turn still reported it. Read `filepath` from permission metadata. The SDK types metadata as Record<string, unknown>, so its keys come from each tool; a live opencode 1.18.18 sends `filepath` (one word) for `edit`, which the previous key list missed. The fallback to `patterns` covered it by accident, and the test that claimed to cover it used `metadata: {}` — a shape OpenCode never emits. Tests now use captured payloads for bash, edit and webfetch. Show tool fields on `waiting` as well as `working`. All three consumers gated on `working`, so a permission request rendered nothing at all; before/after of the sidebar was pixel-identical. The rule now lives in one place (showsAgentToolPreview) because a gate duplicated across three surfaces is a gate that drifts.	2026-08-17 16:37:07 -07:00
Brennan BensonandQA	64de8dd637	fix(workspaces): delete on the confirmed host, and make both hosts' rows selectable (STA-4343) (#15013) ... * fix(workspaces): host-qualified workspace deletion (STA-4343, STA-4448) Squashed integration of PR #14606 + the codex review-loop output, replayed onto current main. Granular history preserved on brennanb2025/sta-4343-review-full. Fixes the regression from #13413: a workspace id is repoId::path with no host component, so the same repo at the same path on two hosts published one id for two workspaces, and deletion routed by that id landed on whichever host routing preferred - usually the ACTIVE one, not the row the user confirmed. - removeWorktree takes a REQUIRED host-qualified WorktreeRemovalTarget; omitting the host is a type error. All destructive callers migrated. - Projections dedup on (host, id), so two hosts render as two selectable rows while the createWorktree/fetchWorktrees race duplicate still collapses. - Ephemeral VM cleanup is host-scoped. It matched on bare workspaceId, so the host-scoped delete path destroyed the SURVIVING host's VM and its unpushed filesystem - a leak fix that had become data destruction. - Selection, keyboard routing, lineage grouping and Space rows carry host identity end to end; fixing the executor dedupe alone would have turned one-row intent into deleting both hosts. Files split to stay under max-lines rather than raising any cap. * refactor: split files that crossed max-lines The review-loop commits used --no-verify, so the pre-commit hook never enforced the caps. Extracted cohesive units rather than raising any limit: renderer teardown, delete-with-toast, pinned-group rows, host-scope helpers, workspace-kind predicates, filter actions, kanban drag selection, the renderer removal result type, and the native-chat persistence tests. * refactor(workspaces): extract cleanup deletion-phase selector Clears the last max-lines violation and the import-type side effect the changed-code gate flagged. * refactor(sidebar): track the delete-dialog extraction modules * fix(workspaces): preserve host identity across remaining surfaces * fix(sidebar): re-carry host through the rewritten palette result model #15170 replaced PaletteSearchResult while this PR was open. Re-applied the host qualification on top of the new model instead of taking either side: results carry worktreeHostId again, and the board filter keys its matched set on host identity rather than the bare id. Known gap, documented in the board test rather than deleted: searchWorktrees resolves evidence through a `documents` map keyed by BARE worktree id, so two same-id host rows collapse before this code sees them. Closing that belongs with the palette work. * test(cmd-j): pin the palette collision gap instead of asserting the old model The palette collision test asserted two host-qualified rows, which #15170's rewrite made unreachable: item ids are bare again and worktreeMap is id-keyed. Rewritten to assert what holds — activation always names a host — and to pin the defect it exposes: two same-id rows render on ONE command value, so React sees duplicate keys and a click on the first row activates the second row's host. That reproduces on main, so it is pre-existing, not from this PR. Pinned rather than deleted so fixing it must update this test. --------- Co-authored-by: QA <qa@local>	2026-08-17 15:57:07 -07:00

Brennan Benson	1a04d292b6	fix(agents): lift the pane retirement fence when a live PTY re-attaches (STA-4114) (#14624) ... * fix(agents): lift the pane retirement fence when a live PTY re-attaches (STA-4114) A detach/reattach cycle retires the pane on both sides — the main hook server's closedAgentStatusPaneKeys and the renderer's recentlyRetiredAgentStatusPaneKeys — and nothing ever cleared either one. The pane then rejected every later working/done event for the rest of its life while Pi kept running normally in the same PTY. Bind the fence to the fact it asserts: retirement claims the pane is gone, and binding a live PTY to that exact pane disproves it. Clear both tombstones at the spawn/attach chokepoint and at the daemon-backed reattach path, so recovery does not depend on the agent starting another turn — a pane re-attached mid-turn only has agent_end left to report, and one re-attached while idle emits nothing at all. Closed-tab tombstones are a separate, stronger claim and are deliberately left standing. * test(agent-hooks): re-arm the idle re-attach test against a turn-boundary fix The idle re-attach assertion posted only before_agent_start, which #14626 turns into a fence-lifting turn boundary. Under that change the test passes whether or not restorePaneAuthority runs, so it stops pinning this PR's mechanism. Assert first on agent_end — a non-turn event — so the test proves the fence was already down when the hook arrived. Verified: with restorePaneAuthority neutered AND before_agent_start added to the restart predicate, the old assertion passes and the new one fails. * fix(agents): lift a retired pane's whole fence, aliases included (STA-4114) Retirement fences the pane, its resolved owner, and every alias of it, then deletes those aliases. Restoring only the key handed to us left the rest standing — and a detached pane's process keeps posting the key it launched under (server.ts:1614), so the canonical re-attach case stayed suppressed with the fence apparently lifted. Verified against the real omp binary: the row came back under the stale launch pane instead of the detached owner. Record what each retirement fenced and replay it as a unit, rebuilding the aliases it deleted. Keys and aliases belonging to a closed tab are skipped, so the stronger claim survives and a live process is never routed back into a closed tab. The record is indexed by every fenced key and bounded at 1024 like the maps it mirrors; an evicted record degrades to the old behaviour. Also records why the renderer's restore IPC is deliberately unguarded: that map is not a mirror of main's (retirePtyAgentLaunchAuthority fences main directly on command-finished and PTY exit, and nothing pushes it back), and it is per-window and non-persisted, so gating the send on a local tombstone reintroduces this bug for exactly those panes.	2026-08-17 15:35:36 -07:00
