* fix(perf): correct three 07-27 perf regressions Traversal capacity cap no longer scales with worker concurrency (#11026). retainWorkspaceSpaceScanEntry charged a traversal-wide entry counter, so N workers each holding a listing multiplied the live charge. At concurrency 48 a 48x2,100 tree (100,848 entries) hit the 100,000 cap while 100x1,500 (150,100 entries, 50% more) passed, and scanLocalWorktree treats the capacity error as terminal, reporting an intact worktree as "Unavailable" with sizeBytes 0. The cap is now per directory listing -- the only quantity fixed by directory shape -- restoring the invariant docs/workspace-space-scan-resource-bounds.md already states. Aggregate live retention stays bounded by the unchanged 64 MiB byte cap. Note: releasing each entry's charge at dispatch (the originally suggested fix) was measured and does not help; the peak is set at admission, before any entry is dispatched. Repo image icons are no longer fully base64-decoded on every snapshot publish (#11012). sanitizeRepoIcon reached decodeBase64Prefix, which sized its buffer to the whole payload to read a 24-byte header, running synchronously inside ipcMain.handle at a 250 ms throttle. Validation is now memoized on source+src in a BoundedMap. Measured for 10 icons x 256 KB: 37.34 ms -> 0.67 ms per publish. One over-long card label no longer discards the entire snapshot (#11012). isDashboardSnapshot was all-or-nothing and dashboard-popout returned early with no log while replaying lastSnapshot, so `orca terminal rename --title "<1025+ chars>"` froze the pop-out board on its last good paint with nothing surfaced. Labels are truncated at the producer, the validator drops only the offending card, and both the rejection and the drop are logged. The bound now lives in the shared snapshot contract so producer and validator cannot drift. Co-authored-by: Orca <help@stably.ai> * fix(perf): charge a scan listing's parent path once, not per entry The 4.1 fix made the entry cap per-listing but left the 64 MiB byte cap charging parentPath.length for every entry in a listing. Because a listing's entries all share one parent-path string, that multiplied the path by the directory's width, so the byte cap measured checkout depth rather than live heap. The reported symptom therefore still reproduced at the production default limits: 48 x 2,100 @ concurrency 48 raised a capacity error once the worktree path passed ~58 characters, while the same layout at concurrency 1 succeeded. The shipped regression test could not see this because it passes maxRetainedBytes: Number.MAX_SAFE_INTEGER, disabling the only cap still in play. Measured at a real 65-char worktree root, 3 of the report's 4 documented layouts still failed. The parent path is now charged once per listing, with its first entry, so an empty listing strands no charge. Per-entry overhead is unchanged at 512 B + name, which still dominates the estimate, so the OOM protection the original PR added is preserved. Adds a production-default-limits case covering the report's layouts under a deep root, plus an assertion that a short and a deep root reach the same verdict -- the path independence docs/workspace-space-scan-resource-bounds.md requires and which no existing test enforced. Co-authored-by: Orca <help@stably.ai> * fix(perf): prove the icon cache by decode count, not wall clock The caching test asserted a per-publish millisecond budget, which failed on CI at 5.64 ms against a 5 ms ceiling. Any threshold flakes on a loaded box, so count real sanitizeRepoIcon entries instead: 10 repos x 20 publishes is 200 icon checks against exactly 1 decode. Added cases pin the cache key (payload and source both re-decode; a cached image verdict never answers for an emoji) and that a rejection is cached too. Also drops budget.entries, which the per-listing cap left as a traversal-wide counter no check reads -- exactly the shape a future guard could reintroduce the concurrency bug from. Co-authored-by: Orca <help@stably.ai> * fix(dashboard): bound the project filter label the whole board rides on #11042 added snapshot-level filterOptions whose project labels are repo.displayName -- the same unbounded source this PR already bounds for card.repoName, but one level up where dropping a card cannot recover it. An over-long project name would fail isDashboardFilterOptions and take the entire snapshot with it, which is the exact frozen-board failure the per-card drop was added to end. Workspace-status labels are already capped at 32 by workspace-statuses.ts, so only projects needed this. Co-authored-by: Orca <help@stably.ai> * fix(dashboard): disambiguate the repo icon cache key The memoization key joined `source` and `src` with a space, but the sanitizer's base64 pattern admits whitespace inside a valid `src`. A rejected icon can therefore split the same concatenation differently and inherit an accepted icon's cached verdict, reaching the pop-out's `<img src>` without ever being sanitized. Length-prefix the source. Co-authored-by: Orca <help@stably.ai> --------- Co-authored-by: Orca <help@stably.ai>
