Part of the DTE-v2 stack; this PR: adds the dynamicThinkingEffort experimental toggle (DTE-1) — the experiment flag in packages/types, its registration in the extension experiment registry (src/shared/experiments.ts), the localized Experimental Settings display, and the accompanying tests. First unit of the series and the pipeline validator for the v2 workflow.
Stack: base = upstream main (cross-fork PR — head easonLiangWorldedtech:feat/dte-v2-1-dynamic-thinking-effort; branches cannot be created in this repo without push access, so the DTE-v2 stack branches live in the fork). U1 is the first unit of the DTE-v2 stack; no lower PRs, so the diff displayed vs main is exactly the standalone diff. The head also additively merges the current upstream main tip (a15ba8c8a — surviving-mutant PR comments #2293, the leading-edge debounce replacement #2268, the Anthropic prompt-cache TTL provider surface and its visual baseline, the i18n load-path and diagnostics work, and the release/infra commits before them) so the unit tracks main and so the gallery harness in this branch is the one visual-regression.yml renders: 379 additions + 2 deletions = 381 lines (≤400 budget). (measured with git diff --shortstat a15ba8c8ace93a5bba85da6d6883963e85f7614e HEAD; the 4 binary PNG baselines below are excluded from the arithmetic)
Main sync (2026-09-05): head e89cceddd additively merges the advanced upstream main (0d937c050 → 0dbd5846f, 5 commits: v3.82.0 release prep #1533, GPT-6 Astra #1506, DeepSeek V4 Flash Vision #1488, the throwIfAborted helper + completePrompt options regression tests #1288, and the async Task.dispose() test-teardown fix#1527). Clean merge — zero conflicts; the standalone diff vs main is unchanged (397 — per-file numstat verified identical to the pre-sync measurement), so no U1 content changed; all local gates re-verified on the sync head (see Verification).

Closes: #2079 (this unit's upstream tracking issue; the unit issue closes when the unit lands).
Refs: contributor-fork series tracker easonLiangWorldedtech/Zoo-Code issue 35 (series-level record only).
Out of scope: the remaining DTE-v2 units (U2+): provider plumbing for the thinking-effort selection, the persisted user setting round-trip, and provider-specific behavior. This unit only introduces the experimental flag, its registry entry, the localized display, and the tests.
CodeRabbit review fixes (head 39762bf81):
RC on ExperimentalSettings.spec.tsx — persistence contract: the round trip is now covered at all three layers this toggle depends on (persisted-setting checklist). webview-ui/src/components/settings/__tests__/SettingsView.spec.tsx: save behavior — a toggle flipped in the Experimental tab is included in the updateSettings payload posted on Save (updatedSettings.experiments.dynamicThinkingEffort === true). src/core/webview/__tests__/webviewMessageHandler.spec.ts: merge semantics of the experiments key — true merges over previously saved values, false overwrites a previously-enabled value, unset resets the entry to experimentDefault; each case asserts the exact contextProxy.setValue("experiments", …) payload and one postStateToWebview(). src/core/webview/__tests__/ClineProvider.spec.ts: getStateToPostToWebview() returns the saved true/false and falls back to experimentDefault when unset.
Follow-up to the same persistence-contract RC — the one untested segment (form toggle → updateSettings payload, i.e. the field-dropped-after-save failure mode the RC called out) is now pinned by the new SettingsView.spec.tsx test above.
Re-review RC on SettingsView.spec.tsx (posted against head 53f22dc24) — the added persistence test covered only the false → true path; a second case now seeds the supported unset representation (dynamicThinkingEffort key omitted), asserts the toggle hydrates as off, round-trips the toggle on and off, and pins the saved payload to dynamicThinkingEffort: false — so the payload contract is asserted for true, explicit false, and unset alike.
RC on vi/settings.json — leftover English model: now mô hình, matching the adjacent description line and all other locales.
Pre-merge "Regression Evidence" warning — visible webview surface now has a durable Playwright baseline: webview-ui/src/components/settings/__tests__/ExperimentalSettings.visual.tsx (+ fixture, registered in playwright/gallery/stories.tsx), one representative snapshot per screen across all four themes, with the Docker-generated baselines committed below, per webview-ui/AGENTS.md.
Re-review RC on ClineProvider.spec.ts (posted against head 9d1f45119) — the unset-case test asserted only toEqual(experimentDefault); it now pins the contract default explicitly (expect(state.experiments).toEqual({ ...experimentDefault, dynamicThinkingEffort: false })), matching the true/false round-trip assertions and proving the exact false value the test name promises.
Pre-submission checklist:
CI locally: pnpm check-types (11/11), targeted vitest re-run on sync head e89cceddd (packages/types 3/3; src: webviewMessageHandler.spec.ts 84/84, ClineProvider.spec.ts 159/159 — main's [Fix] Unit tests report teardown errors after Task cleanup #1527 adds 3 teardown tests, experiments.spec.ts 11/11; webview-ui: ExperimentalSettings.spec.tsx 5/5, SettingsView.spec.tsx 21/21), eslint --prune-suppressions (suppression counts unchanged for every touched file)
Tests accompany all changed lines (local §5.1 mutation gate run, see Verification)
Visual baselines: 4 committed, regenerated this round in the pinned Docker Playwright
container (same image digest as the visual-regression.yml job); no other baseline touched
Line budget measured vs stack base (number above)
Binary files in this PR: 4 PNG visual baselines — webview-ui/src/components/settings/__tests__/__screenshots__/experimental-settings-{dark,light,high-contrast,high-contrast-light}.png (excluded from the line-count arithmetic)
Verification (local, worktree wt-dte-v2-1, base main = 0dbd5846f6eed0a188c4eebd9c77d367fad29ee5; all re-run on sync head e89cceddd):
Visual baselines: superseded this round — regenerated in the image pinned by .github/workflows/visual-regression.yml (mcr.microsoft.com/playwright:v1.64.1-noble@sha256:47b510dd9…,
chromium build 1248) on a tree identical to the PR merge ref; see "Updated this round" below
git diff --shortstat 0dbd5846f6eed0a188c4eebd9c77d367fad29ee5 HEAD → 35 files, 391+ / 6− = 397 lines (31 text files + 4 binary PNG baselines) — per-file numstat verified identical to the pre-sync measurement
Mutation gate (re-run on sync head): node scripts/stryker-diff.mjs ci --base 0dbd5846f6eed0a188c4eebd9c77d367fad29ee5 --head e89cceddd9a4f72fb192212bb30d60318947c399 → extension: 2 valid / 2 killed / 0 survived / 0 no-coverage → Passed (identical 2-mutant selection as the pre-sync head 39762bf81 run — BooleanLiteral→true and ObjectLiteral→{} on src/shared/experiments.ts:29, both killed by the spec's experimentConfigsMap.DYNAMIC_THINKING_EFFORT assertion; the superset-base reproduction also holds: 74 valid / 74 killed)
The extension entry of scripts/stryker-diff.mjs runs the gate in the vitest plugin's
related-discovery mode (vitestRelated: true, discoverRelatedTests: false, so STRYKER_TEST_FILES stays empty) instead of the default explicit-test-file mode. That mode
is already on main (scripts/stryker-diff.mjs:69-70 at a15ba8c8a), and this PR no
longer touches scripts/stryker-diff.mjs or scripts/stryker-diff.test.mjs: the previous
head carried comment-only rewrites of those two files, which were reverted out of the PR in 389813de6 after review (both files are restored to the merge base there and resolve to
main's versions after the a15ba8c8a merge). The note below records why main is configured
this way, because this unit's gate run depends on that configuration.
Why: with @stryker-mutator/core@10.0.0 + @stryker-mutator/vitest-runner@10.0.0,
passing an explicit test-file list makes the mutant-test planner label static mutants
(module-scope code — here: the new experiment-flag constants in src/shared/experiments.ts)
as mutantActivation: 'runtime' (mutant-test-planner.js: mutantActivation: testFilter ? 'runtime' : 'static'), while the vitest plugin activates
static mutants only in beforeAll — after top-level code has already been evaluated.
Result: systematic false Survived for static code — both mutants on src/shared/experiments.ts:29 (BooleanLiteral→true, ObjectLiteral→{}) survived
despite shared/__tests__/experiments.spec.ts asserting the exact replaced values.
With no test-file list the planner plans 'static' activation, the same mutants are Killed (91 related test files executed; killed by the spec's experimentConfigsMap.DYNAMIC_THINKING_EFFORT assertion), and the gate is green
(verified locally on stock 10.0.0, no patched modules).
Revert condition: once the upstream fix lands and the Stryker version is bumped, the extension entry can revert to vitestRelated: false / discoverRelatedTests: true — the
faster, narrowly targeted mode that the webview entry on main already uses
(scripts/stryker-diff.mjs:54-55 at a15ba8c8a); switching both entries in that same
follow-up is the intent.
Local-run note: an interrupted local gate run can leak Stryker's temp sandbox (<package>/.stryker-tmp/), which the pre-commit hook's full pnpm lint then flags with spurious errors (cleanup is skipped on hard kills despite cleanTempDir: "always"); clean runs remove it. Tracked in #1514.
Updated this round (main refresh): merged upstream main (API-lease infra head) into this branch. One conflict: the spec file's foot, where this branch's experiments suite and main's profile-model suite were both appended - kept both blocks. A duplicated blank line the auto-merge left in the provider spec was removed in a follow-up commit. Typecheck, the two affected suites (332 tests), ESLint max-warnings=0 and Prettier clean on the resolved files.
Updated this round (review follow-up, head dadac9270):
scripts/stryker-diff.mjs and scripts/stryker-diff.test.mjs reverted out of the PR
(389813de6): both hunks rewrote comments only, and main already carries vitestRelated: true / discoverRelatedTests: false for the extension entry. The
"Mutation gate note" above is corrected to say that, and the v1.62.1 image claim in
Verification is corrected to the digest visual-regression.yml pins.
Merged upstream maina15ba8c8a (a34589932) — clean merge, zero conflicts. The unit
needs this refresh: main mounts the real @vscode/webview-ui-toolkit in the Playwright
gallery (the toolkit mock is gone) and AppProviders no longer pre-loads translations, so
this unit's four baselines had been measured against the pre-refresh rendering (CI rendered
488×589 against 488×543 committed).
Regenerated the four experimental-settings-*.png baselines inside the pinned CI image
(dadac9270): reproduced the failure first (identical pixel counts to CI's log — 37618 /
16638 / 40967 / 16740 for dark / light / high-contrast / high-contrast-light), then test:visual:docker:update scoped with --grep 'renders the experimental settings section' --update-snapshots, which rewrote exactly those four files (sha256 of every other __screenshots__/*.png identical before and after), then re-ran the four tests unmodified → Running 4 tests using 4 workers ... 4 passed. All four measure 488x589; nothing was
hand-edited.
Added an experimental Dynamic Thinking Effort setting to the settings interface, with translations across supported languages.
The setting is off by default and saves your selected preference. Manual adjustment in chat remains available; per-request behavior is not yet supported.
Adds dynamicThinkingEffort as an optional, disabled-by-default experiment. The changes include tests for its schema, settings interactions, and webview state, plus localized setting labels and descriptions.
Changes: Dynamic thinking effort experiment
Layer / File(s)
Summary
Experiment contract and default packages/types/src/experiment.ts, packages/types/src/__tests__/experiment.test.ts, src/shared/experiments.ts, src/shared/__tests__/experiments.spec.ts
Adds the experiment ID and optional boolean schema field. The shared registry sets it to disabled by default. Tests cover schema parsing and experiment configuration.
Webview experiment state src/core/webview/__tests__/ClineProvider.spec.ts, src/core/webview/__tests__/webviewMessageHandler.spec.ts
Adds tests for projecting saved and default values into webview state, and for updates that merge or replace saved experiment values.
Settings toggle and presentation webview-ui/src/components/settings/__tests__/*, webview-ui/playwright/gallery/stories.tsx, webview-ui/src/i18n/locales/*/settings.json
Adds tests for rendering, toggling, and saving the setting. Adds a gallery story, themed visual test, and setting labels and descriptions in 18 locales.
Zoo-Code-Org/Zoo-Code#1522: The next DTE unit builds on this experiment flag and overlaps in the shared experiment files.
Merge Risk: Low · up to dadac
The default-off preference is mergeable with bounded follow-up: correct the misleading chat-control description and strengthen focused settings tests. The inspected save path preserves values and awaits storage before posting state.

Full details: Title check
Explanation
The title "feat(settings): dynamic thinking effort experimental toggle (DTE-1)" names the primary change: a new experimental toggle for dynamic thinking effort in the settings UI. The changeset matches this. It adds the flag in packages/types, registers it in src/shared/experiments.ts, adds the localized Experimental Settings toggle, and adds tests. The title uses a Conventional Commits prefix and a ticket tag (DTE-1). The ticket tag is internal shorthand and adds no meaning for a reader scanning history. The title is short and specific enough to pass.
Full details: Description check
Explanation
The description follows the repository template closely. It links issue #2079 under Related GitHub Issue, and it explains the scope, out-of-scope items, test procedure, checklist, visual baselines, and verification steps. It has some problems. The description is very long and includes stacking, merge, and mutation-gate history that does not belong in the PR body. Several sections are dense and repeat the same test results across multiple places. The Test Procedure section is mostly a list of command results, not steps a reviewer can repeat for the feature. The Get in Touch section is left as a template placeholder with no Discord username. The Documentation Updates section has no box checked. The Pre-Submission Checklist has several boxes checked, but the description does not clearly state the checked Scope item fits one feature, since the PR includes a Stryker and main-sync history. Overall the required content is present, so the check passes, but the author should trim the history and fill in the missing Get in Touch and Documentation Updates fields.
Full details: Linked Issues check
Explanation
Active directly linked issue #2079 requires: the dynamicThinkingEffort flag in packages/types, its registry entry, the localized Experimental Settings toggle, the provider projection, and focused tests. Changed files in the whole-PR diff against merge base a15ba8c cover each item. packages/types/src/experiment.ts adds the ID to experimentIds, ExperimentId, and Experiments. src/shared/experiments.ts adds DYNAMIC_THINKING_EFFORT to EXPERIMENT_IDS and experimentConfigsMap with enabled: false. Eighteen settings.json locales add the name and description. The provider projection is covered by ClineProvider.spec.ts, which asserts that getStateToPostToWebview() returns saved true and false values and the false default when unset. Focused tests exist in packages/types experiment tests, src/shared/__tests__/experiments.spec.ts, and ExperimentalSettings.spec.tsx (render state, toggle calls). Closed issue #1527 is context only and adds no requirements. Non-coding items (visual baselines, Stryker configuration notes, line budget, CI and local gate reports) do not change this verdict. Gate results are author-reported and were not independently re-run in this assessment. Test-only evidence for the provider projection relies on existing generic code paths, since no ClineProvider.ts change appears in the changed-file list.
Full details: Out of Scope Changes check
Explanation
All changed files relate to the dynamicThinkingEffort flag. Production changes are limited to the type and registry entries in packages/types/src/experiment.ts and src/shared/experiments.ts, plus locale strings. Tests cover those entries and their generic settings paths. The visual fixture, story registration, and visual spec support the toggle's Playwright baseline. The scripts/stryker-diff.mjs and scripts/stryker-diff.test.mjs edits were reverted out of the PR (389813de6), so they are not part of the reviewed diff. No per-request thinking-effort resolution (U2), task-local runtime state (U3), Anthropic output_config.effort wiring (U5), or provider-specific effort behavior appears in the changed files. The webviewMessageHandler.spec.ts and SettingsView.spec.tsx additions are tests of the existing experiments save and merge paths. They pin the flag's persistence contract and add no new behavior. Because #2079 places the persisted-settings round-trip in U4, these tests sit at the boundary. They are judged supporting tests for this flag and not U4 implementation. The merge of upstream main in this head adds no separate feature code to the reviewed diff, because the whole-PR base is now a15ba8c8a.
Full details: Security Boundaries
Explanation
No changed path meets the stated security failure conditions. The PR adds an optional boolean experiment flag that defaults to false, plus settings text and tests. The flag has no execution or approval-control consumer in the inspected code.
Full details: Persistence Integrity
Explanation
The PR adds an optional experiment flag and a false default. The existing settings path merges experiment values and awaits persistence. The settings consumer also treats an omitted flag as false. No changed persistence path meets the failure criteria.
Full details: Lifecycle Resource Cleanup
Explanation
The changed production code adds an experiment ID, schema field, and disabled registry entry. The settings component renders the entry through its existing toggle path. No changed lifecycle path creates or retains resources or duplicates work after cancellation, disposal, or restart.
Full details: Regression Evidence
Explanation
The new toggle lacks an executable Playwright snapshot. ExperimentalSettings.visual.tsx:6-7 requests a mount fixture, but playwright/coverage-fixture.ts:1-21 extends @playwright/test only with collectCoverage. The gallery defines window.mount, not a Playwright fixture. The new tests cannot reach their screenshot assertions, despite the committed baselines.
Resolution
Provide a Playwright mount fixture that opens the gallery and calls window.mount, or mount the story through page in the new visual test. Verify all four snapshot comparisons.

Assert that the experiments write settles before the state post.
The new webviewMessageHandler - experiments tests check the setValue arguments and that postStateToWebview runs once. They do not detect a post that runs before the awaited write settles, or a removed await. Either regression leaves these assertions unchanged.
Comparing mock.invocationCallOrder does not close this gap. It records when each call starts, so a setValue call without await still records first. Hold the write open with a deferred mock, as the existing telemetry ordering test does, and assert that the post waits for it.
Deferred-write test to add to the experiments describe block
This test fails if the post runs before the write settles, or if the await is removed. It documents the current write-then-post order and does not indicate a production defect.

Add a deferred-write ordering test in the experiments describe block for
webviewMessageHandler: hold contextProxy.setValue open, verify
postStateToWebview has not run while the write is pending, then release the
write and verify the handler completes and posts state once.

If your PR changes anything a user would notice at a glance — layout, spacing, theme tokens, brand elements, gradients, mask/blur effects, hover/empty/error states — **add a `*.visual.tsx` snapshot to the same PR**. Do not attach screenshots to the PR description as evidence; commit the baseline instead so future PRs get regression coverage automatically.

## Persisted Setting Checklist
- [ ] Add focused tests for: UI binding/save behavior, persistence or normalization, and the saved value returned by `getStateToPostToWebview()`. Include both `true` and `false`/unset cases when defaulting can hide omissions.
Both stryker-diff hunks in this PR rewrote comments only: the extension entry
already carries vitestRelated: true / discoverRelatedTests: false on main
(scripts/stryker-diff.mjs:69-70 of a15ba8c), and the assertions in
scripts/stryker-diff.test.mjs already match main. Restore both files to the
merge base so the mutation-gate settings and their explanatory comments stay in
one place; this unit is the dynamicThinkingEffort flag.
Upstream refresh for the round. The gallery harness on main now mounts the real
@vscode/webview-ui-toolkit (the toolkit mock is gone) and AppProviders no longer
pre-loads translations, so the experimental-settings baselines this unit added
were measured against the pre-refresh rendering. Merging main first keeps the
branch tree identical to the merge ref the Visual Regression workflow renders,
which is what the regenerated baselines in the following commit are measured
against.
The four baselines were measured against the pre-refresh gallery rendering.
Upstream main renders the real @vscode/webview-ui-toolkit in the gallery (the
toolkit mock is gone), so the story is 46 px taller and CI's required
webview-visual check failed all four themes.
Reproduced first, in the image pinned by visual-regression.yml
(mcr.microsoft.com/playwright:v1.64.1-noble@sha256:47b510dd9..., chromium build
1248, tree = this branch merged with a15ba8c - the same content as the PR merge
ref):
Error: expect(locator).toHaveScreenshot(expected) failed
Expected an image 488px by 543px, received 488px by 589px. 37618 pixels
(ratio 0.14 of all image pixels) are different.
with 16638 / 40967 / 16740 differing pixels for light / high-contrast /
high-contrast-light - byte-for-byte the same diff counts CI reported for head
301c1c5, which is the evidence that this container reproduces the CI rendering.
Then regenerated with test:visual:docker:update scoped to the story (--grep
"renders the experimental settings" --update-snapshots), which re-wrote exactly
these four files: sha256 of every other __screenshots__/*.png is identical before
and after. All four are 488x589, matching the measured CI height; no dimensions
were hand-edited.
All three review threads are addressed, replied to and resolved.
scripts/stryker-diff.mjs + scripts/stryker-diff.test.mjs are out of the PR (389813de6 restores both to the merge base; after the main merge they resolve to main's copies, so git diff a15ba8c8a HEAD -- scripts/ is empty). main already runs the extension entry in related-discovery mode (vitestRelated: true / discoverRelatedTests: false, scripts/stryker-diff.mjs:69-70), so the "switches the entry" wording in the Mutation gate note was wrong — the body now says the mode is already on main and keeps the upstream-defect explanation as context for why main is configured that way.
The four experimental-settings-*.png baselines are regenerated inside the image visual-regression.yml pins (mcr.microsoft.com/playwright:v1.64.1-noble@sha256:47b510dd9…, chromium build 1248) — the body previously claimed v1.62.1, which is also corrected. Reproduced first on a tree identical to the merge ref (Expected an image 488px by 543px, received 488px by 589px, 37618 / 16638 / 40967 / 16740 differing pixels for dark / light / high-contrast / high-contrast-light — the same counts CI logged for 301c1c5a1), then regenerated with test:visual:docker:update scoped by --grep 'renders the experimental settings section' --update-snapshots. Exactly those four files changed: sha256 of every other __screenshots__/*.png is identical before and after. Re-ran the four tests unmodified in the same image → Running 4 tests using 4 workers … 4 passed, and CI's webview-visual is green on dadac9270. Nothing was hand-edited.
Merged upstream maina15ba8c8a (a34589932), clean. Standalone diff is now 33 files (29 text + 4 binary baselines), 379 additions + 2 deletions = 381 lines, still inside the 400 budget.
Re-verified locally on the merged head: pnpm check-types 11/11, vitest 3/3 (packages/types) + 138/138 (webviewMessageHandler.spec.ts, experiments.spec.ts) + 43/43 (ExperimentalSettings.spec.tsx, SettingsView.spec.tsx), ESLint --max-warnings=0 clean in src, packages/types and webview-ui with src/eslint-suppressions.json byte-identical, Prettier clean, translation scan clean across 18 locales.
State check for the maintainers holding the changes-requested (edelauna, 04:34:36Z): all three review threads on this PR are answered in-thread and resolved, and every check is green at dadac9270 - the six hard-required lanes (check-translations, platform-unit-test ubuntu + windows, compile, knip, e2e-mock, webview-visual) plus mutation-diff, extension-host-visual, theme-fixtures, invisible-chars, dependency-review and Build test VSIX.
What changed in response to the scope comments: both scripts/ stryker hunks were reverted out of this PR (main already carries the mode at a15ba8c8a, so git diff a15ba8c8a HEAD -- scripts/ is empty), the four experimental-settings visual baselines were regenerated in the image visual-regression.yml actually pins (mcr.microsoft.com/playwright:v1.64.1-noble@sha256:47b510dd9…) with only those four PNGs changing, and the PR body was corrected (real image pin, budget re-measured at 381 changed lines against a15ba8c8a).
The awaiting-author label keeps coming back because it tracks the review state rather than the responses, so it needs a maintainer re-review or a dismissal of the changes-requested - there is no author-side item left. I am deliberately not firing a bot re-review request here: CodeRabbit's verdict is not what blocks this merge, and the hourly review budget is better spent where a bot pass can actually clear the state.

The
extensionentry ofscripts/stryker-diff.mjsruns the gate in the vitest plugin'srelated-discovery mode (
vitestRelated: true,discoverRelatedTests: false, soSTRYKER_TEST_FILESstays empty) instead of the default explicit-test-file mode. That modeis already on
main(scripts/stryker-diff.mjs:69-70ata15ba8c8a), and this PR nolonger touches
scripts/stryker-diff.mjsorscripts/stryker-diff.test.mjs: the previoushead carried comment-only rewrites of those two files, which were reverted out of the PR in
389813de6after review (both files are restored to the merge base there and resolve tomain's versions after the
a15ba8c8amerge). The note below records why main is configuredthis way, because this unit's gate run depends on that configuration.
Why: with
@stryker-mutator/core@10.0.0+@stryker-mutator/vitest-runner@10.0.0,passing an explicit test-file list makes the mutant-test planner label static mutants
(module-scope code — here: the new experiment-flag constants in
src/shared/experiments.ts)as
mutantActivation: 'runtime'(mutant-test-planner.js:mutantActivation: testFilter ? 'runtime' : 'static'), while the vitest plugin activatesstatic mutants only in
beforeAll— after top-level code has already been evaluated.Result: systematic false
Survivedfor static code — both mutants onsrc/shared/experiments.ts:29(BooleanLiteral→true, ObjectLiteral→{}) surviveddespite
shared/__tests__/experiments.spec.tsasserting the exact replaced values.With no test-file list the planner plans
'static'activation, the same mutants areKilled(91 related test files executed; killed by the spec'sexperimentConfigsMap.DYNAMIC_THINKING_EFFORTassertion), and the gate is green(verified locally on stock 10.0.0, no patched modules).
Upstream tracking:
Killedwhen activation timing is fixed), plus a secondaryreloadEnvironmentcapability gap.Revert condition: once the upstream fix lands and the Stryker version is bumped, the
extensionentry can revert tovitestRelated: false/discoverRelatedTests: true— thefaster, narrowly targeted mode that the
webviewentry on main already uses(
scripts/stryker-diff.mjs:54-55ata15ba8c8a); switching both entries in that samefollow-up is the intent.
Local-run note: an interrupted local gate run can leak Stryker's temp sandbox (
<package>/.stryker-tmp/), which the pre-commit hook's fullpnpm lintthen flags with spurious errors (cleanup is skipped on hard kills despitecleanTempDir: "always"); clean runs remove it. Tracked in #1514.Updated this round (main refresh): merged upstream
main(API-lease infra head) into this branch. One conflict: the spec file's foot, where this branch's experiments suite and main's profile-model suite were both appended - kept both blocks. A duplicated blank line the auto-merge left in the provider spec was removed in a follow-up commit. Typecheck, the two affected suites (332 tests), ESLint max-warnings=0 and Prettier clean on the resolved files.Updated this round (review follow-up, head
