feat(core): add ObservationRegistry with completeness scope and close semantics, wired into Task (U5c-7, split of #1991) - #2396
One unit from the #1991 split plan (tracking issue comment 6756389509 carries the planned-and-issued boundary, and that same comment now carries the record of the boundary being changed — read it before the diff). It ports scaffold row U5c-7 whole out of #2357 verbatim: the in-memory ObservationRegistry, its own spec, and the Task.ts consumer with the two Task specs that exercise it. Content is byte-identical to the source pair 5319fe91fb0c… → d6fa7117e07b…; nothing here was authored on this lane.
This head replaces a smaller head (0975cb445afd…, 216 a+d, registry + spec only) because CI's own required knip context reported the registry unused in production mode. The reason and the measurement are in the boundary comment; the short form is below. A second commit, d0496c57245de7bc4b5c76e303c30ba6d44debd8, then answered CodeRabbit review 5836217589; the three answers, their measurements and the wording the bot still wants changed are in the last section.
387 = 84 + 134 + 34 + 50 + 85. Three blobs moved between the fold head and this one: the registry spec is 134 added lines (the afterEach import and block, the trailing vi.useRealTimers() removed), Task.ts 34 (the three rewritten comment blocks), Task.dispose.test.ts still 50 with the disposal awaited. The cumulative diff from the base is still additions only, because the review fixes deleted lines that this unit's own earlier commit had added - git diff --numstat 18861b2e3572..d0496c5724 prints 34/0, 50/0, 85/0, 134/0, 84/0. Each head blob equals the blob at the source head, printed from git (git cat-file -p <source-head>:<path>), so fidelity is byte identity rather than a claim about intent. Task.dispose.test.ts is not a new file: it exists on main and gains a describe block here; the only two new paths are the registry and its spec.
The consumer, quoted
At the source head, src/core/task/Task.ts:
:109 — import { ObservationRegistry } from "./observationRegistry"
:302 — readonly observationRegistry = new ObservationRegistry()
:3788 — this.observationRegistry.close() inside dispose(), between removing event listeners and disposing the tool registry
Those three lines are why the registry is not test-only: close() on disposal is the behaviour Task.dispose.test.ts asserts (clears the per-Task observation registry on disposal), and the registry's own spec asserts the semantics it depends on (close drops every entry and reports the registry closed, observe is a no-op after close, so a read resuming after disposal cannot re-record the file, records completeness, defaulting to complete).
Currency, measured at the base this head is pushed onto
Head d0496c57245de7bc4b5c76e303c30ba6d44debd8 (the fold b9b85debe3fff8615649a872cff5ad79f33a72c9 plus one review-answer commit), rooted on 18861b2e357203e6cb4d93930aa2ed122b1eecea (upstream/main), which is what git merge-base upstream/main <head> prints at this head too, and the gate (scripts/stryker-diff.mjs, imported as a module so the limits are its own constants) reports:
25 counted executable lines of 500, 15 selectors of 400
advisories: ["src/core/task/Task.ts:4459: mutation exclusions must use …"] - the same directive as at the fold head, where the gate reported it at 4458; the two added comment lines moved the reported line and the directive text is untouched
Task.ts contributes 5 of the 25 (302, 408, 3618, 3632, 3789 at this head; 302, 406, 3617, 3631, 3788 at the fold head - the same code, renumbered by the added comment lines); the registry its 20. zdt split verify on the re-derived contract (.tmp-b1-1404/r30-contracts/U5c7fold.json, base and head as above, allowNew limited to the two new paths) exited 0 with standalone: 384 a+d / 5 files UNDER-SOFT and five rows OK (content subset of source) … byte-identical; the round-31 contract (r31-contracts/U5c7foldR31.json, same base, head d0496c57245d) exits 1 - see the deviation paragraph at the end.
The knip evidence, in the form CI runs it
At the previous head, CI's knip context — one of the six required by ruleset 15494382 — failed: job 129579712187 ran pnpm test:knip-policy (# tests 8 / # pass 8 / # fail 0, including ok 4 - a production file imported only by tests is still reported as unused) then pnpm knip (exit 0) then pnpm knip:production, which printed Unused files (1) → src/core/task/observationRegistry.ts and ELIFECYCLE Command failed with exit code 1.. Main at 18861b2e3572… is success on that context (129577571680), so the row belonged to the unit.
Locally, in the install-matching worktree wt-r304-u5c2-matched on pinned node v22.23.4, with the three script spellings read from git show b9b85debe3:package.json rather than the checkout:
block
at fold head
at main tip (same worktree, git checkout --detach, HEAD restored after)
pnpm test:knip-policy
exit 0, # tests 8 / # pass 8 / # fail 0
exit 0, # tests 8 / # pass 8 / # fail 0
pnpm knip
exit 0
exit 0
pnpm knip:production
exit 0
exit 0
Install provenance for those cells: pnpm-lock.yaml is blob a949abf3770df5d1539250e3acfa2e3a7cf8111d at a7157157239a…, at 18861b2e3572… and at this head; no package.json, turbo.json, .npmrc, .nvmrc or .husky path differs between them; the three @roo-code/* workspace links in this worktree realpath inside it; all thirteen workspace node_modules trees are present except packages/config-typescript, which declares no dependencies at all.
Mutation band on this unit's own selectors
Run in the same worktree on node v22.23.4 against stryker.config.mjs, with --mutate carrying exactly the 15 selectors from the gate manifest (this is the fold head's run; the run at d0496c57245d is in the last section):
instrumented 11 mutants against the gate's 400 ceiling; Task.ts's five selectors yield 3 of them (UpdateOperator at 3617 and 3631, CallExpression at 3788 — the field initialiser at 302 and the statement at 406 instrument to nothing), the registry yields 8 (BooleanLiteral 32/44/72, ConditionalExpression 45 ×2, ObjectLiteral 48, CallExpression 60/73)
real run exit 0, tally {"Killed": 11} — 0 survived, 0 timed out, 0 no-coverage; report .tmp-b1-1404/r30-reports/extension/mutation.json (pair 9362c7bdbdc6e121)
One instrument fact worth recording for the next unit that touches Task.ts: with the config the gate passes for this package (vitest.config.ts) the dry run instrumented the same 11 mutants but its initial test run timed out — Stryker's dryRunTimeoutMinutes default, 5, is set neither by stryker.config.mjs nor by the gate, and with vitest.vitest.related on, the initial run pulls every spec that reaches the mutated files, which for Task.ts means a large slice of the extension suite. With vitest.core.config.ts the same initial run took 3 m 29 s (1,227 tests) and the band finished in about 4 minutes. If CI's leg hits the same wall it degrades to an advisory, not a red row (scripts/stryker-diff.mjs:806 catches the failed leg and pushes its message into advisories), and the separate 12-minute ceiling at :442 prints "Split the PR or obtain a maintainer-reviewed narrow exclusion."
Controls — the fix proven by what fails without it
Everything below ran in wt-r304-u5c2-matched on node v22.23.4 with CI=1, against vitest.core.config.ts, and every mutation was applied by a guarded patch (exact-match, exactly-one-hit) and restored before the next step; the restored blob pair 6d057ff9c1b150e3 was re-printed after each restore and git status was empty at the end.
Reverted fix (production file deleted, consumer and both specs kept): Test Files 2 failed (2) with Serialized Error: { code: 'ERR_MODULE_NOT_FOUND' }; pnpm --dir src run check-types exit 1 printing core/task/Task.ts(109,37): error TS2307: Cannot find module './observationRegistry' or its corresponding type declarations. plus the same at core/task/__tests__/Task.dispose.test.ts(6,37) and core/task/__tests__/observationRegistry.spec.ts(3,37). Restored: 29/29 green.
close() drops this.retired = true (3,010 → 2,988 B): Tests 3 failed | 26 passed (29), exit 1 — ObservationRegistry > closure on task disposal > close drops every entry and reports the registry closed (expected false to be true), … > observe is a no-op after close, so a read resuming after disposal cannot re-record the file (expected 1 to be +0), and Task dispose method > clears the per-Task observation registry on disposal (expected false to be true).
Baseline after restores: Test Files 2 passed (2), Tests 29 passed (29), exit 0.
The one advisory, answered rather than edited away
Task.ts:4458 reports mutation exclusions must use "// Stryker disable next-line MutatorName: concrete reason"; broad or unreasoned exclusions are not allowed. The line in question is a pre-existing directive on main — identical text sits at main's line 4425 — and this unit's added lines shift it to 4458 at the fold head and 4459 at d0496c57245d (the gate's own comment stamp at this head is quoted in the last section). The gate validates directives against every line of a file that enters the changed set (:238 passes new Set(source.split(/\r?\n/).map((_, index) => index + 1))), and :86-87's regex requires the mutator list without a space after the comma, so ConditionalExpression, EqualityOperator is rejected even though the reason is concrete and every mutator is named. It is advisory, not blocking; editing a directive that belongs to #2357 is a maintainer's call, so I am reporting it, not silently rewriting it. My probe against :86-87 marks two lines in this file FAIL and five PASS — 4458 and 4894 (main's 4425 and 4861, same text) — and only the first offender is reported (4458 then, 4459 now) because validateDisableDirectives throws on the first offending line.
Corrections to what I published at the previous head
I printed 3,010 B / 85 lines and 4,084 B / 133 lines. The LF counts are 84 and 132 — I counted a phantom line after the final newline; 84 + 132 is exactly the 216 additions.
I wrote that the gate declares vitestConfig: "vitest.stryker.config.ts". That is scripts/stryker-diff.mjs:53, the webview entry rooted at webview-ui, and webview-ui/vitest.stryker.config.ts does exist. The entry that governs this unit is :62, vitestConfig: "vitest.config.ts" for the extension package, and src/vitest.config.ts exists. So last round's band ran on a config I chose, not the one CI passes; this round I ran both and reported the difference.
What CI printed at the fold head (kept as the record; the read at this head is in the last section)
knip → success (the only failing required context at the previous head); check-translations, compile, e2e-mock, platform-unit-test (ubuntu-latest) and (windows-latest) are unchanged by this content and were green at the previous head.
mutation-diff (advisory context) → priced on 25 lines / 15 selectors; my local band says 11 mutants, 11 killed. Because the head now carries 1 advisory, mutation-pr-comment.yml:350 (informative = report.blocking > 0 || report.advisories > 0) means a bot-posted mutation report comment should appear on this PR where it did not at the previous head (blocking: 0 advisories: 0 posted nothing).
Review state stays untouched by the push in the human sense: there is no approving review on this PR to dismiss, and CodeRabbit's row is gated by the workflow-managed coderabbit-review-active label, which I neither add nor remove.

Rows behind those answers, all in worktree wt-r304-u5c2-matched on pinned node v22.23.4, CI=1, run from src against vitest.core.config.ts, with the GIT_* key list of the runner environment printed on each row as empty (a GIT_TERMINAL_PROMPT in the environment makes simple-git's guard throw and turns a test row into an instrument row):
observationRegistry.spec.ts: Test Files 1 passed (1), Tests 13 passed (13), exit 0, 393 ms. Negative control on the same pinned node with a node-side patch: forcing the re-observe test's assertion to throw gives Test Files 1 failed (1), Tests 1 failed | 12 passed (13), exit 1 in 0.9 s - the 12 tests after the throwing one still pass because the restore is now in an afterEach; the file was restored to its committed blob (7286cc79bba703d2d70de23bebafc26a5798edeb, content pair d522bf4dac6ce609) and git status was empty afterwards.
Task.dispose.test.ts: Test Files 1 passed (1), Tests 16 passed (16), exit 0, 7.41 s, with await other.dispose() in the finally and the test marked async.
Task.spec.ts -t 'cancellation generation' (invoked through pnpm exec, since pnpm run swallows -t): Tests 3 passed | 210 skipped (213), exit 0, 9.42 s - the three tests that pin the counter across requestAbort(), requestDispose() and a resume.
prettier --check on the three touched files: exit 0 (All matched files use Prettier code style!). eslint --prune-suppressions --max-warnings=0 on the three files from src: exit 0. pnpm run check-types from src: exit 0. The --prune-suppressions pass rewrote src/eslint-suppressions.json cosmetically (tabs to two spaces across 1,326 lines, 30,910 to 33,294 B) while changing 0 of its 265 entries and the 2,868 suppressed total, so it was reverted; the file is not in the diff and its blob stays ae3d504003d7e616b129986c252cc97a35b7b568. Instrument churn, not content.
Commit and push: d0496c57245d was made with hooks enabled (core.hooksPath = .husky/_) and the push ran with --force-with-lease=vps2f-1914-u5c7a-observation-registry:b9b85debe3fff8615649a872cff5ad79f33a72c9 (expected value taken from git ls-remote in the same script, lease passed as one token), no --no-verify. The pre-push hook is in the log: > roo-code@ check-types then the turbo graph printing Tasks: 12 successful, 12 total, Cached: 10 cached, 12 total and Changeset files: 10; PUSH_EXIT=0 captured immediately after the command, b9b85debe3..d0496c5724 HEAD -> vps2f-1914-u5c7a-observation-registry, and the log's own ls-remote after the push prints d0496c57245de7bc4b5c76e303c30ba6d44debd8.
Mutation band at this head on the gate's own 15 selectors: instruments 11 mutants of the 400 ceiling - Task.ts 3 (UpdateOperator 3618, UpdateOperator 3632, CallExpression 3789) and observationRegistry.ts 8 (BooleanLiteral 32 and 44, ConditionalExpression 45 twice, ObjectLiteral 48, CallExpression 60, BooleanLiteral 72, CallExpression 73) - with selectors 302 and 408 yielding no mutant at all (a readonly getter-ish field initializer and a number = 0 field generate nothing). Real run on vitest.config.ts (the config the gate declares for this package at scripts/stryker-diff.mjs:62) exit 0, tally {"Killed": 11}, 0 survived, 0 timed out, 0 uncovered; report .tmp-b1-1404/r31-reports/extension/mutation.json (pair b374a69eba95b136). Both dry legs at this head hit Stryker's dryRunTimeoutMinutes ceiling of 5 (initial test run timed out on vitest.config.ts after 5 m 05 s and on vitest.core.config.ts after 5 m 03 s) while the real leg of the same script finished in 5 m 29 s - another lane's Stryker preflight was running on this box at the same time, so those two dry rows are about the host and only the real row is a content row.
Gate currency did not move with the fixes, and the CI-side stamp agrees: 25 of 500 counted executable lines, 15 of 400 selectors, one advisory. The gate's own report comment on this PR (6757812879) was rewritten in place at 03:52:52Z and its header reads head:d0496c57245de7bc4b5c76e303c30ba6d44debd8 blocking:0 advisories:1.
State at this head, read once at 03:58:00Z. All six contexts required by ruleset 15494382 are completed / success on d0496c57245d: check-translations 129616360720 (03:47:34Z), platform-unit-test (ubuntu-latest) 129616361040 (03:53:17Z), platform-unit-test (windows-latest) 129616361297 (03:55:16Z), compile 129616361044 (03:51:09Z), knip 129616361078 (03:48:09Z), e2e-mock 129616361055 (03:51:31Z). Advisory mutation-diff 129616364606 completed / success (03:52:36Z). extension-host-visual 129616365136 was in_progress and is left unclaimed - it is not in the required set. CodeRabbit 129616374363 is skipped because the workflow-managed coderabbit-review-active label is absent (labels: []). The review endpoint at 03:58:02Z returned 7 rows: 5836217589 CHANGES_REQUESTED (03:11:53Z, standing - a push does not clear it) and 6 zero-byte COMMENTED rows, three from my thread replies (03:40:26Z, 03:40:28Z, 03:46:01Z) and three from the bot's replies to them (03:41:16Z, 03:41:25Z, 03:47:16Z); a thread reply creates such a row, so a rising review count is not a review pass. mergeable: true, mergeable_state: blocked, requested reviewers taltas, edelauna, JamesRobert20, with require_code_owner_review on the ruleset: what is missing is a human signature, not more content.
Deviation, stated where a reviewer will find it. The three rewrites in Task.ts are comment-only changes to content this unit ports from #2357, so they are deviations from the fidelity pair 5319fe91fb0c…d6fa7117e07b, declared in .tmp-b1-1404/r31-contracts/U5c7foldR31.json (design.deviations, notes). zdt split verify on that contract exits 1 with VIOLATION foreign-content: src/core/task/Task.ts - unit added 17 line(s) / deleted 0 line(s) NOT in the source diff and prints OK (source + 2 sanctioned new lines) for both test files, while its budget line reads standalone: 387 a+d / 5 files UNDER-SOFT. The tool can sanction added lines inside tests (allowNew, allowNewIn) and has no channel to sanction a production-file deviation, so this FAIL is a limitation of the instrument and is being circulated rather than hidden; it is not a check on this PR, and the reason the comment rewrite is worth the deviation is that at main's tip cancellationGeneration does not exist in Task.ts at all, so the ported wording would have entered main describing a transition the run-state kernel does not have.
Not in this unit
No .changeset file, no CHANGELOG edit, no eslint-suppressions.json change (the file is not in the diff, so no count moves), no Stryker directive edit. The other priced rows of #1991's scaffold — the ReadFileTool/indentation-reader pair, safeWriteJson.test.ts, McpHub.ts + spec, and the 1,140 a+d readFileTool.spec.ts row — are separate units and separate PRs.
Task cancellation and disposal events are tracked more consistently, including when a task resumes after delegated work.
File observations are kept separate for each task and cleared when the task is disposed. Observations recorded after disposal are ignored.
File observations include a completeness indicator. Recording another observation for the same file replaces the previous one.
Task now owns a per-task registry for file observations and closes it during disposal. Abort and disposal requests increment a cancellation-generation counter. Tests cover registry operations, task lifecycle, and generation updates.
A new registry stores file version, observation time, and completeness by path. Each Task has its own registry. Disposal closes the registry and clears its entries. Tests cover registry operations, task isolation, and disposal.
Abort and disposal requests increment cancellationGeneration before dispatching their events. Tests cover increments across abort, resume, and disposal. The persistence test removes a pre-existing ui_messages.json before saving.
Zoo-Code-Org/Zoo-Code#2384: Adds the same Task registry and cancellation-generation fields, disposal behavior, and tests.
Zoo-Code-Org/Zoo-Code#2359: Uses Task.observationRegistry and cancellation state for guarded-write checks.

Explanation
No changed lifecycle path introduces a concrete resource leak or duplicate work. Task.disposeOnce() closes the new registry, and ObservationRegistry.close() clears its entries and rejects later observations. The new cancellation counter has no production reader.
Full details: Regression Evidence
Explanation
The disposal fence still lacks coverage while cleanup is pending. Task.ts:3632,3789 advances the generation and closes the registry before asynchronous cleanup completes. The deferred-cleanup test does not check either effect, and the new disposal assertions run only after dispose() resolves.
Resolution
Add a Task test that holds disposal cleanup pending. Before releasing cleanup, assert that the generation advanced, the registry closed, and a late observation is ignored.

So CI generated 8 mutants and killed all 8 — 0 survived, 0 timed out, 0 no-coverage, 8 against the 400-mutant limit — matching my local band (Instrumented 1 source file(s) with 8 mutant(s), tally {"Killed": 8}, exit 0) line for line. The artifact's per-mutant rows land at lines 32, 44, 45 (twice), 48, 60, 72, 73, the same eight positions my run reported.
No zoo-code-mutation-report comment exists on this PR, and that is the instrument behaving as designed, not a leg that never ran: mutation-pr-comment.yml:350 sets informative = report.blocking > 0 || report.advisories > 0, this report is blocking:0 advisories:0, and line 427 prints no surviving mutants and no existing comment; nothing posted. I report the absence as a measurement: at 02:17:05Z this PR had three issue comments (CodeRabbit skip notice 3,937 B, review-state bot 552 B, codecov 391 B), no review rows and no inline comments, and none of them carries the marker.
The red row is mine, and the command that caught it is not the command I ran
CI's own control on main at 18861b2e357203e6cb4d93930aa2ed122b1eecea — its check-runs paginated to its own total_count 291, read 02:19:01Z — reports knip completed/success (job 129577571680, completed 02:01:57Z). So the failure below is attributable to this cut, not to the tree it sits on.
The knip job runs two things. First pnpm test:knip-policy (node --test scripts/knip-policy.test.mjs), which passes here in full, including the subtest that names this exact case: ok 4 - a production file imported only by tests is still reported as unused. Then pnpm knip → pnpm knip:production → knip --production --treat-config-hints-as-errors, which printed:
My own gate row was pnpm exec knip in the install-matching worktree wt-r304-u5c2-matched on pinned node v22.23.4: exit 0, silent. That is the weaker instrument, and the gap is a trap worth stating plainly for anyone else running this repo's gates: pnpm exec knip green is not the knip context green — the context adds --production and --treat-config-hints-as-errors, and it is the production mode that treats a test-only importer as no importer at all.
Disposition
This head is half of scaffold U5c-7 with its consumer deliberately deferred, and CI has answered the question I left open in the body: a production file whose only importer is its own spec is not mergeable on its own here. The answer is content, not a cosmetic export invented to appease a linter, and the body already prices both shapes:
fold the Task.ts consumer into this PR — 384 a+d, 25 counted executable lines, 15 selectors, still under both caps — which gives the registry a production importer in the same commit;
or, if a maintainer prefers the two-step, the consumer lands as a separate PR stacked on this one, and this PR stays red on knip until that one is merged.
I am holding the fold for the next round rather than pushing a fix that carries no content: this round's push budget went to 0975cb445afd (single parent a7157157239a), hooks proved by output — Running check-types in 13 packages, Tasks: 12 successful, 12 total, Cached: 0 cached, 12 total, Time: 20.72s, Changeset files: 10 — and I am not pushing an eslint-only or knip-only commit in front of a decision.
CodeRabbit will not review this head until the repo's own automation applies coderabbit-review-active. Its notice (comment 6756904550) reads Auto reviews are limited based on label configuration … Required labels (at least one): 1 … coderabbit-review-active, and the review-state bot (comment 6757009530) says review-state labels are workflow-managed and must not be edited by hand. I added none.
…er (U5c-7, split of Zoo-Code-Org#1991)
ObservationRegistry records per-file observation state with a completeness flag,
refuses further recording once closed, and is dropped when a task is disposed.
It lands together with the Task-side code that imports it, because the repo's own
policy asserts that a production file imported only by tests is still reported as
unused (scripts/knip-policy.test.mjs) and knip --production is a required check.

Advisory findings
src/core/task/Task.ts:4459: mutation exclusions must use "// Stryker disable next-line MutatorName: concrete reason"; broad or unreasoned exclusions are not allowed.
The third path and why it is here: the unit now carries scaffold U5c-7's consumer half — Task.ts (:109 imports ./observationRegistry, :302 constructs it, :3788 calls close() inside dispose()), plus Task.dispose.test.ts (+50, which asserts the disposal clearing) and Task.spec.ts (+85). CI's own policy test in the knip job says it plainly — ok 4 - a production file imported only by tests is still reported as unused — so a production file whose only importer is a test is, by this repo's definition, unused, and stacking the consumer behind this PR would have left the red standing.
Measured, not asserted. The exact CI knip sequence ran locally in the install-matching worktree wt-r304-u5c2-matched on pinned node v22.23.4, with script spellings read from git show b9b85debe3:package.json: pnpm test:knip-policy 8/8 exit 0, pnpm knip exit 0, pnpm knip:production exit 0 at this head, and 0/0/0 at 18861b2e3572… as the control in the same worktree. @roo-code/types resolves its import condition from ./src/index.ts, so nothing I ran needed the built entry; the pre-push hook did build it (its graph printed @roo-code/types:build with dist\index.cjs 607.34 KB). Band on the 15 union selectors: 11 mutants against the 400 ceiling — Task.ts's five selectors yield 3 (UpdateOperator 3617/3631, CallExpression 3788; 302 and 406 instrument to nothing), the registry 8 — real run exit 0, tally {"Killed": 11}. Controls with named rows: production file deleted → Test Files 2 failed (2) / ERR_MODULE_NOT_FOUND and pnpm --dir src run check-types exit 1 with core/task/Task.ts(109,37): error TS2307: Cannot find module './observationRegistry'; guard removed → Tests 2 failed | 27 passed (29); close() dropping this.retired = true → Tests 3 failed | 26 passed (29) naming close drops every entry and reports the registry closed, observe is a no-op after close… (expected 1 to be +0) and Task dispose method > clears the per-Task observation registry on disposal; complete: boolean = true → false → Tests 2 failed | 27 passed (29) on expect(obs.complete).toBe(true); every mutant restored to pair 6d057ff9c1b150e3 and 29/29 green after.
Two instrument facts, both quoted rather than inferred. (1) The gate hands the extension package vitestConfig: "vitest.config.ts" (scripts/stryker-diff.mjs:62) — my earlier claim that it declares vitest.stryker.config.ts was a misread of line 53, the webview entry, and is corrected in the body. On my box, that faithful config instrumented the same 11 mutants but its initial related run died at Stryker's 5-minute dryRunTimeoutMinutes default, which neither stryker.config.mjs nor the gate overrides; on CI the same leg finished in 4 m 52 s (gate invocation 03:00:51 → advisory emitted 03:05:43) against the related set CI listed (Task.spec.ts, Task.dispose.test.ts, 20+ ClineProvider/ask-* specs), so the ceiling is a Windows-speed risk, not a property of the diff. (2) The single advisory — src/core/task/Task.ts:4458 — is pre-existing content: the identical directive sits on main at line 4425, this unit's 33 added lines shift it, :238 validates every line of a changed file, and :86-87 rejects a mutator list written ConditionalExpression, EqualityOperator with a space after the comma even though the reason is concrete. 4894 has the same shape and is never reported because the validator throws on the first offender. It is advisory, not blocking, and rewriting #2357's directive is a maintainer's call.
Push discipline. One push, --force-with-lease=vps2f-1914-u5c7a-observation-registry:0975cb445afd… (expected value read from ls-remote immediately before), no --no-verify; the hook chain ran to completion in the log — 12 check-types tasks successful, changeset guard reporting Changeset files: 10 — and the push printed + 0975cb445a...b9b85debe3 … (forced update). My push script then lost $LASTEXITCODE to my own edit, so the exit code is not in the log; what is: ls-remote after the push returns b9b85debe3fff8615649a872cff5ad79f33a72c9, the PR GET reports that head with base 18861b2e3572…, git merge-base upstream/main <head> prints the same base, and all five path blobs at the delivered head equal both what I priced and the blobs at the source head d6fa7117e07b…. My harness also printed PUSH_EXIT= empty; that is my defect, not the push's.
State at the read moment 03:11:00Z (GET /commits/b9b85debe3…/check-runs?per_page=100, total_count 21, all on page 1): 18 success, 1 cancelled (mutation-diff 129599579123, cancelled by this push at 03:00:10Z), 2 in progress — CodeRabbit's fresh run 129602686789 and extension-host-visual 129599560582, which I leave unclaimed.

- Around line 17-29: Ensure fake timers used by the ObservationRegistry test are
restored even when an assertion fails: move vi.useRealTimers() out of the test
body and into an afterEach cleanup for the describe block, or use try/finally
around the test body. Keep the timer restoration scoped to this test suite.
Review comments at @src/core/task/__tests__/Task.dispose.test.ts:
- Around line 144-146: Update the “owns a per-Task observation registry” test to
be async and await other.dispose() in its finally block. Remove the void
fire-and-forget call and swallowed rejection so the test waits for cleanup and
disposal failures surface.
Review comments at @src/core/task/Task.ts:
- Around line 400-406: Rewrite the comments around `cancellationGeneration` and
`resumeAfterDelegation()` to describe repository behavior only: state that
`requestAbort()` and `requestDispose()` increment the monotonic counter, and
identify guarded writes as a future consumer rather than claiming a current
comparison exists. Remove merge-history references and correct the resume
comment to match the run-state kernel, which does not clear the legacy `abort`
flag on resume.

- observationRegistry.spec.ts: restore real timers from an afterEach on the
describe block, so a failing assertion in the fake-timer test cannot leave the
rest of the file running on fake timers.
- Task.dispose.test.ts: await the second Task's disposal in the finally block
instead of firing it and forgetting it, so teardown is deterministic and a
rejection surfaces.
- Task.ts: describe cancellationGeneration in repository terms. The run-state
kernel has no transition that clears latches.abort, so abort stays true across
resumeAfterDelegation() and only the counter keeps a cancelled run apart from
the resumed one; the guarded write the comment documents has no production
reader yet, so the comment no longer claims a comparison that does not happen.
The production change is comment-only: the mutation gate still prices 25 counted
executable lines and 15 selectors for this unit.
Round 31: review 5836217589 answered, one push, one read of the armed contexts
Head is now d0496c57245de7bc4b5c76e303c30ba6d44debd8 (the fold b9b85debe3ff plus one review-answer commit), pushed at 03:46:46Z with --force-with-lease=vps2f-1914-u5c7a-observation-registry:b9b85debe3fff8615649a872cff5ad79f33a72c9 - expected value read from git ls-remote in the same script, lease passed as one token, no --no-verify. The hook ran and the log shows it: > roo-code@ check-types, the turbo graph Tasks: 12 successful, 12 total, Changeset files: 10, then b9b85debe3..d0496c5724 HEAD -> vps2f-1914-u5c7a-observation-registry, exit 0 captured straight after the command.
The three inline threads are answered in place, each with the rows behind it (replies 4520856838, 4520857077, 4520892819, plus 4520985642 for the follow-up the bot raised on the third): the afterEach restore of real timers in observationRegistry.spec.ts, await other.dispose() in the disposal test's finally, and the Task.ts cancellation comments rewritten in repository terms. All three claims were checked against b9b85debe3ff before anything was edited, and the third is backed by grep counts (3 production occurrences of cancellationGeneration, 9 test reads, no production reader) and by runState.ts (writes abort: true at 171 and 184, never clears the latch; resumeAfterDelegation() never touches runState).
Each required context, from one read at 03:58:00Z on this head:check-translations success (129616360720, 03:47:34Z); platform-unit-test (ubuntu-latest) success (129616361040, 03:53:17Z); platform-unit-test (windows-latest) success (129616361297, 03:55:16Z); compile success (129616361044, 03:51:09Z); knip success (129616361078, 03:48:09Z); e2e-mock success (129616361055, 03:51:31Z). Advisory mutation-diff success (129616364606, 03:52:36Z) and its report comment (6757812879) was rewritten in place at 03:52:52Z with header head:d0496c57245de7bc4b5c76e303c30ba6d44debd8 blocking:0 advisories:1. extension-host-visual (129616365136) was in_progress at the read and is left unclaimed: it is not in the required set. CodeRabbit (129616374363) is skipped because the workflow-managed coderabbit-review-active label is absent (labels: []), so a full re-review is gated by that label.
Review state, said plainly:5836217589 CHANGES_REQUESTED (03:11:53Z) still stands - a push does not clear it. The review endpoint at 03:58:02Z listed 7 rows: that one plus six zero-byte COMMENTED rows, three created by my thread replies (03:40:26Z, 03:40:28Z, 03:46:01Z) and three by the bot's replies to them (03:41:16Z, 03:41:25Z, 03:47:16Z), so a growing review count is not a growing review. mergeable: true, mergeable_state: blocked, requested reviewers taltas, edelauna, JamesRobert20: the remaining requirement is a human code-owner signature, which no push of mine can supply.
Cost, re-measured at the delivered head rather than carried over:selectFromGit from scripts/stryker-diff.mjs with mergeBase 18861b2e357203e6cb4d93930aa2ed122b1eecea prices package extension (vitest.config.ts, vitestRelated true) at 25 of 500 counted executable lines and 15 of 400 selectors - unchanged, because every production line I touched is a comment; only numbering moved (406 to 408, 3617 to 3618, 3631 to 3632, 3788 to 3789) and the one pre-existing directive advisory moved from being reported at 4458 to 4459. Band on those 15 selectors: 11 mutants of the 400 ceiling, all killed, 0 survivors and 0 timeouts, with Task.ts:302 and Task.ts:408 yielding no mutant at all. Width from the base is 387 / 0 - git diff --shortstat prints 5 files changed, 387 insertions(+), GitHub prints +387 / -0, and zdt's budget line prints 387 a+d / 5 files UNDER-SOFT.
Two things that are not hidden: (1) the Task.ts rewrites are comment deviations from this unit's ported source pair (they are not in 5319fe91fb0c...d6fa7117e07b), declared in .tmp-b1-1404/r31-contracts/U5c7foldR31.json, and zdt split verify on that contract exits 1 with VIOLATION foreign-content: src/core/task/Task.ts because the tool can sanction test-side additions (allowNew, allowNewIn) and has no channel to sanction a production-side deviation; zdt is a split-plan tool, not a status on this PR, and all six required contexts are green. They are worth having because cancellationGeneration does not exist in Task.ts at main's tip, so the ported wording would have entered main describing a kernel transition that does not exist. (2) The bot's remaining ask on the third thread - describing the guarded-write effect as future behavior - is accepted and the replacement text is quoted in reply 4520985642; it is comment-only, prices to zero counted lines, and rides this unit's next content push rather than costing a second push for a sentence.

403-404: Describe cancellation separation as future behavior.
No production code reads cancellationGeneration, so the counter does not yet separate runs for a guarded write. The comments in requestAbort() and requestDispose() make the same current-effect claim. The existing review thread already requests this correction.
The fence comments asserted an effect no production reader produces yet: that the
counter separates a cancelled run from the run that resumes afterwards, and that a
write still parked on its path chain publishes after disposal. At this head
cancellationGeneration has three production sites (the field and the two increments
in requestAbort and requestDispose) and no production reader; nine assertions in
src/core/task/__tests__/Task.spec.ts 4786-4851 are what pin it. The three blocks now
say the counter is monotonic, that a future guarded write would compare the value it
captured when queued with the value at publish time, and that no such write exists
today.
Comment-only: the non-comment content of src/core/task/Task.ts is byte-identical
(sha256/16 60377E70665E7EE0 over 5,530 non-comment lines before and after), so the
mutation gate prices 0 counted executable lines for this commit.

What this PR is
One unit from the #1991 split plan (tracking issue comment 6756389509 carries the planned-and-issued boundary, and that same comment now carries the record of the boundary being changed — read it before the diff). It ports scaffold row U5c-7 whole out of #2357 verbatim: the in-memory
ObservationRegistry, its own spec, and theTask.tsconsumer with the two Task specs that exercise it. Content is byte-identical to the source pair5319fe91fb0c…→d6fa7117e07b…; nothing here was authored on this lane.This head replaces a smaller head (
0975cb445afd…, 216 a+d, registry + spec only) because CI's own requiredknipcontext reported the registry unused in production mode. The reason and the measurement are in the boundary comment; the short form is below. A second commit,d0496c57245de7bc4b5c76e303c30ba6d44debd8, then answered CodeRabbit review5836217589; the three answers, their measurements and the wording the bot still wants changed are in the last section.The diff — 5 paths, 387 additions, 0 deletions

Task.ts: with the config the gate passes for this package (vitest.config.ts) the dry run instrumented the same 11 mutants but its initial test run timed out — Stryker'sdryRunTimeoutMinutesdefault, 5, is set neither bystryker.config.mjsnor by the gate, and withvitest.vitest.relatedon, the initial run pulls every spec that reaches the mutated files, which forTask.tsmeans a large slice of the extension suite. Withvitest.core.config.tsthe same initial run took 3 m 29 s (1,227 tests) and the band finished in about 4 minutes. If CI's leg hits the same wall it degrades to an advisory, not a red row (scripts/stryker-diff.mjs:806catches the failed leg and pushes its message intoadvisories), and the separate 12-minute ceiling at:442prints "Split the PR or obtain a maintainer-reviewed narrow exclusion."Controls — the fix proven by what fails without it
Everything below ran in

Task.ts:4458reportsmutation exclusions must use "// Stryker disable next-line MutatorName: concrete reason"; broad or unreasoned exclusions are not allowed.The line in question is a pre-existing directive on main — identical text sits at main's line 4425 — and this unit's added lines shift it to 4458 at the fold head and 4459 atd0496c57245d(the gate's own comment stamp at this head is quoted in the last section). The gate validates directives against every line of a file that enters the changed set (:238passesnew Set(source.split(/\r?\n/).map((_, index) => index + 1))), and:86-87's regex requires the mutator list without a space after the comma, soConditionalExpression, EqualityOperatoris rejected even though the reason is concrete and every mutator is named. It is advisory, not blocking; editing a directive that belongs to #2357 is a maintainer's call, so I am reporting it, not silently rewriting it. My probe against:86-87marks two lines in this file FAIL and five PASS — 4458 and 4894 (main's4425and4861, same text) — and only the first offender is reported (4458 then, 4459 now) becausevalidateDisableDirectivesthrows on the first offending line.Corrections to what I published at the previous head

The entry that governs this unit is:62,vitestConfig: "vitest.config.ts"for the extension package, andsrc/vitest.config.tsexists. So last round's band ran on a config I chose, not the one CI passes; this round I ran both and reported the difference.What CI printed at the fold head (kept as the record; the read at this head is in the last section)
