See [`docs/reference/windows-terminal-shell-selection.md`](./docs/reference/windows-terminal-shell-selection.md).
 - **Windows setup scripts**: the setup/issue-command runner is a `.cmd` batch file unless the script starts with a `#!` line — never derive that from the user's terminal-shell preference, and never launch a `.cmd` runner with a bare `cmd.exe /c` from a Git Bash pane (MSYS rewrites the `/c`). See [`docs/reference/windows-setup-shell.md`](./docs/reference/windows-setup-shell.md).
-- **Windows child processes**: start them through `runProcess`/`spawnProcess` in `src/shared/child-process/` — never `child_process` directly. It pins `windowsHide`, refuses `shell: true`, and encodes `.cmd`/`.bat` arguments so neither `CommandLineToArgvW` nor `cmd.exe` mangles them. A ratchet test fails on any new direct import. Recognised npm/pnpm `.cmd` shims are resolved to their real target so the spawn skips `cmd.exe` entirely; see [`docs/reference/windows-cmd-shim-resolution.md`](./docs/reference/windows-cmd-shim-resolution.md) before adding a shim shape or debugging one.

 - **Ripgrep**: Orca bundles `rg` for every platform, WSL, and SSH remotes. Spawn it through `spawnBundledRipgrep` (main) or `resolveRelayRipgrepCommand` (relay), never a bare `'rg'` — Windows resolves a bare name in the spawn cwd before PATH. Don't add git/readdir fallbacks locally; the relay's chain exists only for hosts an upload never reached.
 - **Windows process enumeration**: read the table through `src/main/windows/windows-process-table.ts`, never by forking `powershell.exe`. See [`docs/reference/windows-process-enumeration.md`](./docs/reference/windows-process-enumeration.md).
 - **Windows MSYS/Git Bash panes**: their children break away from the per-PTY job unless it is created without `JOB_OBJECT_LIMIT_BREAKAWAY_OK`, and a `conpty.node` built before that fix passes every existing gate. Before changing the per-PTY job or debugging `windows-msys-job.win32.test.ts`, read [`docs/reference/windows-msys-job-breakaway.md`](./docs/reference/windows-msys-job-breakaway.md).

+C34 is a sixth Asia cell at the C31 shape in `asia-east2-c`, so the six Asia cells spread 2/2/2. It
+was its own topology wave, registered alone as migration-only, and the director was configured with
+`cell-ids` set to C34, all on 2026-10-05. It launched as a migration-only spare and now has a
+promotion wave of its own, with the same five-minute canary C30 and C31 ran. The canary lands on
+C34 because it is the emptiest general Asia cell once promoted. Promotion compares the director's
+serving digest and C34's runtime digest with the one `image-digest` input, so C34 must first be
+rolled to the director's image. That roll is a same-cap wave that enters and leaves
+migration-only, so it moves nobody. C34 stays in the same-cap migration-only list until its promotion
+succeeds, because a same-cap job reads a cell's class from that list, not from the selector. It
+then moves to the general list and the fleet pool list together, as its own reviewed change,
+before any same-cap wave names C34 again. Between promotion and that change, do not run a same-cap

Stage at least 1,000,000 xterm cells, hide all six warm managers, emit an initial working title followed by 30 timed real-PTY spinner frames and a final idle title per worktree, and observe a second real session-tabs subscription plus the production renderer store. Require exactly two transport envelopes and two title mutations per worktree, no decorative title crossing either boundary, and positive decoded-envelope bytes. Enable ordinary parking with the lossy retention budget disabled, require exactly one mounted manager and five parked tabs, at most 45% retained cells, no more than 16 MiB heap growth, and under 500 ms timer drift. In headed mode, require the host renderer to remain on its original workspace with zero target terminal managers mounted throughout client park, reveal, and live I/O. While a tab is parked, require authoritative terminal.read to observe new PTY output; reveal it and require the original PTY, a marker within the requested 5,000-row history, the parked marker, and post-reveal input/output. Drive 24 real PTY title trackers in distinct worktrees through 40 decorative spinner frames each, then 40 spinner frames alternating with Cursor's bare native identity redraw, using fake clocks. Require all 2,880 raw chunks exactly and zero host session-tabs publications, serialized bytes, renderer apply calls, and renderer store mutations. Continue decorative evidence beyond 30 minutes, require exactly one refresh per worktree per 15-minute lease through a FIFO spaced by at least 50 ms, and require all 24 viewer statuses to remain working and fresh; then require one exact semantic idle transition and one visible-output chunk per PTY. Require ordinary and interior-Braille title changes to publish. Drive 64 host PTYs through ten 80 ms synthetic title frames, require zero paired client events after the first frame per PTY while all 640 local frames remain observable, attach a late client and require one current frame per PTY, then require semantic bell and idle transitions on both clients. Reconstruct a legacy subscribed stream with no outputPause capability, hide a chatty pane, require no hidden xterm writes, reveal it, and require one authoritative snapshot plus continued live output. Drop and acknowledge output only for one original paired-client stream, prove the fixture process consumed input while the host model advanced and the client stayed stale, then require the command snapshot probe to replace that stream, repaint exact fixture output, preserve authoritative PTY identity and target-tab cardinality, and resume live I/O. For a client without a delivered sequence, require the first numeric probe to establish a baseline without replacement, a same-sequence probe to remain attached, and a later advanced probe to replace only that stream. Withhold the first encrypted shared-control ready frame, start one RPC, trigger a status-probe refresh, and require two connections, one host delivery, successful response, and zero retained request bytes. Admit 128 active streams, reject the 129th as retryable, release one stream, then require the retry to attach and publish a snapshot without multiplying retained subscribers. Disable terminal.paired-parking.v1 and require the same oracle to fail before parking, while the legacy limit-one fallback separately passes. Also preserve truncated first paint, ACK-starved same-PTY recovery, responsive silent-command snapshot probes, dead-stream probe timeout recovery, and queued manual-disconnect fencing.",

Applying PR #14071's launcher exec semantics with PID delivery left v1.4.180 red and the candidate green, proving the launcher and Electron/Xvfb fixes are independent and composable.

Explicit foreground status reads still work. Ten minutes of unchanged retries cause zero session writes and never revisit settled workers. Existing backoff remains capped at 30 seconds so late availability recovers automatically; timers stop on convergence or cancellation, and foreign identities never arm local timers. An additive partial index contains only the five potentially active worker states and is maintained by SQLite for old writers too. Repair queries avoid scanning finished history and return without a write transaction when no stale worker exists; actual repairs re-read under the writer lock and remain atomic. The index is built once per database and adds maintenance on worker-state changes. One recovery pass resolves each workspace once and keeps no lookup cache between passes. A same-machine 100,000-assignment before/after run observed repair 37.75ms to 17.89ms, no-op scan 25.62ms to 4.35ms with zero mutations, and subsequent database open 37.42ms to 17.11ms; The later partial-index/read-only revision observed no-op repair 0.016ms, complete healthy database open 12.44ms, and first index-build plus repair/open 63.14ms for 100,000 assignments and 1,000 stale workers.

- * Every in-page hop between page routes, and whether the opener's grants cover the target.

- * cover, which is the fix; this is the census that says which hops those are, so adding a grant to
- * a route — or a new push between two — shows up as a change here rather than as a verb that
- * silently refuses on a device.
- *
- * Openers are every page route, not the one that pushes: on a wide layout `app/h/_layout.tsx`
- * renders the worktree-list sidebar beside every `/h` route, and its header pushes tasks. That is
- * what makes a pairwise pin the wrong shape — the sidebar reaches everything.
- *
- * Targets are the routes the app navigates to, read from its call sites rather than from every
- * `/h/...` template in the sources: a route's own mount declares its pathname, so harvesting those
- * made every declared route reachable and the filter inert.

-/**
- * Which hops the rule hands to the shell, pinned by name.
- *
- * Empty would mean every page route covers every other, which is not a property this codebase has
- * and not one to assume: the point of the pin is that a new entry appears when a route's grants
- * grow, and that the entry is read before it ships rather than found on a device.
- *
- * What is NOT here is the point of the census. `files/[worktreeId] -> files/preview/[worktreeId]`
- * is absent because the preview declares no more than the explorer, so that hop stays in the
- * document — which is C3.1's pairwise pin, now a consequence of the rule rather than a rule of its
- * own. Absent for the same reason, and measured rather than reasoned: the four hops the worktree
- * list and the history screen make into the explorer and its preview, which left this list when
- * those two declared the `externalLink` their own protocol wall reaches and took it from 23 rows
- * to 19. The four now declare the same four grants, so a tapped file costs no native frame and no
- * second bridge session.
- *
- * What remains beside the session rows is twelve: four openers holding no `native.clipboard.write`
- * into the three routes that ask for it — tasks, the hub and review.
- *
- * Absent for the same reason, and the reason C4 registered its two routes in one PR:
- * `source-control ⇄ review` in both directions. The hub's rows push review and review replaces
- * back, and the two declare the same five grants, so both hops stay in the document. Either one
- * landing alone would have put a handoff — a new native screen and a new bridge session — between
- * a changed-file row and its diff.
- *
- * The seven C7 rows are the same rule with the arrows all one way: every one `X -> session`, one
- * from each other page route. The session screen's thirteen grants are a strict
- * superset of every other route's, so nothing can reach it under the grants it was opened with —
- * and nothing it pushes to leaves, because its own seven targets each declare a subset. A row in
- * the other direction would mean a route had grown a grant the session lacks.

+## Worktree activation belongs to a viewer
+
+Worktree creation and activation default to the host desktop for host/CLI requests,
+and to the caller for paired desktop/web requests. Mobile creation still activates
+the host renderer to provision setup and default tabs. A headless host does not
+borrow a paired client's view. Catalog and session updates continue to reach every
+subscriber independently of navigation.
+Headless host/CLI creates provision their shells, setup, and default tabs on the
+execution host in the background, without depending on an observer to open them.
+The same fallback applies when an attached host renderer is unavailable or
+reloading, including explicit `all` requests that target the host; availability is
+checked after creation, rather than before its awaits.
+
+`activateWorktree` client events carry an optional `navigation` field. Only explicit
+`clients` or `all` requests publish these events; updated clients ignore events
+without that address, including implicit broadcasts from older hosts. This is an
+optional JSON field (Rule 1): older clients ignore it and still understand explicit
+activation. The new host's default publication changes deliberately remove implicit
+navigation for older clients too, rather than retaining the unwanted behavior.
+An older host cannot express explicit follow intent to an updated client, so that
+client must open the workspace itself.
+Accepted navigation is also fenced through repository/worktree discovery; bridge
+cleanup, reconnection, or re-pairing revokes any activation still awaiting a fetch.
+
+Older CLIs hardcode `navigation: 'all'` for `--activate` and `--run-hooks`. The host
+recognizes their `cliProvenanceRequest` and normalizes that automatic target to
+`host`. An API caller without the CLI marker can still explicitly request `clients`
+or `all`. Neither creation nor activation navigates remote clients by default.
+
+Coverage: `multi-client-navigation-isolation.integration.test.ts` exercises real
+paired WebSocket clients and host/headless creation, the renderer bridge tests
+exercise older unaddressed publications, and
+`paired-worktree-activation-isolation.spec.ts` checks a paired desktop remaining in
+a local workspace while its remote catalog updates.

-in an allowlist that only shrinks.
-
-Its limits are worth being explicit about, because they decide how much it is
-worth trusting:
-
-- **It cannot see the dangerous part.** Whether a swallowed value is later
-  cached or gates discovery is dataflow, not syntax. Every allowlisted entry is
-  currently safe; the guard does not verify that and cannot.
-- **It is scoped, not global.** The same shape appears ~850 times across `src/`
-  and is usually correct, because for most callers a failure genuinely does mean
-  absent. Enforcing it repo-wide would be noise. It only matters where the
-  answer describes a WSL distro.
-- **It catches a shape, not a mistake.** Code can conflate failure and absence
-  without ever writing `catch { return false }`.
-
-So it does not prevent the bug. What it does is stop a new swallow site
-appearing in these modules without someone stating why the value is safe to
-pin — which is the review conversation that was missing all three times.
+Review the caller as well as the catch: whether a fallback is cached or gates discovery is a dataflow question. Returning `false`, `[]`, or `null` after a failure can be safe for some operations, but a WSL probe must preserve the distinction between absence and a distro that could not be reached. Prefer behavioral tests that exercise probe failure, discovery, caching, and recovery together.

-- **`fork` is not scanned.** Node forwards `windowsHide` to spawn at runtime, but `ForkOptions` does not declare it, so the two live sites — `main/daemon/daemon-init.ts` and `main/plugins/plugin-host-process.ts` — cannot be fixed without a cast. Both are console-subsystem children on Windows.
-- **The allowlist is file-granular, so an allowlisted file is blind.** ~18 of its entries are false positives (`RegExp.prototype.exec`, `provider.exec`, and files the lexer desynced on), and each carries a standing pre-approval for a real regression in that file. Those entries also cannot be retired by fixing code, so the list cannot reach zero as written. Making it call-granular is the fix.
-- **`stripComments` has no desync report.** The fail-closed check runs on already-stripped text, so a regex literal containing a slash-star can still swallow code silently. No occurrence in `src/` today.

Every guard fix in this workstream that was verified only by reading was wrong — three consecutive attempts at an exact lexer each shipped a desync that _reduced_ the offender count, which read as progress. Plant at least: a plain call, one in a template-literal-heavy file, one in a regex-heavy file, `windowsHide: false`, a ternary first argument, and a renamed import.

+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes

+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You

+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+// The narrow grammar a provider adapter speaks to the timeline assembler.
+//
+// The adapter knows the provider's dialect; the assembler knows the timeline. An adapter parses
+// provider traffic into these semantic events and never writes a journal row or mints a journal
+// identity: every key here is the provider's own id (a turn, a tool call, a message, a thread),
+// or a name the adapter keeps stable for something the provider does not name. The assembler
+// spells those keys as row ids, scopes rows to turns, and owns the turn and item rules in
+// `agent-session-journal-types.ts`.
+//
+// Rules an adapter can rely on:
+// - One assembler lives exactly as long as one provider child: a new process is a new assembler,
+//   with a new acquisition generation.
+// - Only `turn.open` opens a turn. Items, text and requests never do: one that arrives with no
+//   turn open and names none is written as a thread row. An adapter whose provider starts work on
+//   its own (a background wake, auto-compaction) decides that a turn began and says `turn.open`
+//   before that work's items.
+// - `join.turn` attaches a row to the turn the provider says it belongs to, open or not.
+// - A turn settles once, with only the provider's verdict. A row the journal already holds is
+//   never written back to an earlier state: a settled turn stays settled, a settled tool keeps its
+//   terminal body, an answered request stays answered.
+// - A turn another writer settled (a person's Stop) is over here: its pending requests are
+//   cancelled, and text still streaming into it is dropped until the provider's end of that turn
+//   or the next `turn.open`. Its running tool calls are still the provider's: a close reported
+//   after the Stop lands as reported, and whatever is still running settles at the provider's
+//   `turn.end` for it (or the next `turn.open`, or `session.ended`).
+// - An event the sink refused changed nothing. Re-apply the same event to retry it (after
+//   `backpressure`); `failed` and `closed` are final.
+// - A provider item is (thread, id): the same id on another thread is another item. Text and
+//   full snapshots of one id are one row, and its close settles it for both.
+// - After `session.ended` every event is dropped.

- * Ratchet: `onPtyExit` is the reaper for per-PTY runtime state, and every

- *
- * `ptyLifecycleGenerationById` was added next to ~25 siblings the reaper already
- * deleted — including `agentPromptExplicitStatusFloorByPtyId`, set two lines below
- * it in `advancePtyLifecycleGeneration` — and was simply never added to the list.
- * Nothing failed, so it accumulated one number per PTY for the life of the process.
- * A hand-maintained delete list has no way to notice the next omission; this does.
- *
- * The field list is read off a real instance rather than parsed out of the source,
- * so a map declared in any of the ~90 mixin files is covered the moment it exists.
- * Every field must land in exactly one bucket, and the two "cleaned elsewhere"
- * buckets are verified against real source rather than trusted as an allowlist.

- * - Transcripts (readiness-census-transcripts-<shard>.test.ts): every recorded agent PTY transcript
- *   is replayed chunk by chunk into a real runtime pane at its recorded grid, once with the agent
- *   known and once agent-unknown. Each frame records the ranked verdict the moment the chunk lands
- *   and had the stream then gone quiet, what `terminal wait --for tui-idle` started there returns
- *   (at once or on its first poll tick), and the same on a clockless (restored or adopted) pane.
- * - Synthetic (readiness-census-synthetic.test.ts): every TuiAgent under a bounded matrix of title,
- *   first-party status, screen, foreground process and output clock
- *   (readiness-census-synthetic-matrix.ts says which cross-product and why).
- *
- * Baselines live in __fixtures__/readiness-census/, one per replayed pane (run-length encoded per
- * frame) or agent. Any difference fails with the subject and frames or cases that changed. If the change is intended, regenerate with
- *
- *   UPDATE_READINESS_CENSUS=1 pnpm test src/main/runtime/readiness-census

- * and review the JSON diff (the commit hook's oxfmt pass reflows it; the census only parses it).

- * Guard the one WSL failure mode that keeps coming back in different clothes:

- *
- * `catch { return false }` is not itself the bug -- an uncached caller just
- * asks again and the answer corrects itself. The bug is what happens when that
- * value is cached or used to gate discovery: a distro that was busy for one
- * second reports no git, or no agent sessions, for the rest of the session.
- * It has shipped that way at least three times (see the allowlist header).
- *
- * A repo-wide rule is not workable -- the shape appears ~850 times in `src/`
- * and is usually correct, because for most callers a failure genuinely does
- * mean absent. It is only dangerous where the answer describes a WSL distro,
- * which is why the scan is scoped to the probe modules that own those answers.
- *
- * This guard cannot see the dangerous part. Whether a swallowed value gets
- * pinned is dataflow, not syntax. What it can do is stop a new swallow site
- * from appearing in these modules without someone saying out loud why it is
- * safe to pin -- which is the review that was missing all three times.
