≤400-line redo of #1338 — DTE series 2/5, unit 3/5

Task-local runtime thinking-effort state on Task: the in-memory override
channel, its per-request delivery at all four createMessage sites, and the
profile-switch re-capture in updateApiConfiguration. Transient state only — nothing is persisted; persistence is the next unit (U4).

GitHub's displayed diff vs main is cumulative over the unmerged lower units
(U1 #1521, U2 #1522); the standalone range below is the review target — the displayed number shrinks as they merge. Merge this PR only after its stack
base PR has merged.

Budget (plan §2: a+d ≤400 soft target; ≤1000 hard)

2 files changed, 417 insertions(+), 1 deletion(-) = 418 — soft target 400 exceeded by 18, CR-driven (see the amendments below); hard cap 1000 ✓

File	a+d
`src/core/task/Task.ts`	102+/1−
`src/core/task/__tests__/Task.runtime-thinking-effort.test.ts` (new)	315+

Budget deviation note (plan §2.6). The plan estimated U3 at ~355
(Task +132/− + tests ~20); those numbers were stale. Measured against the
union, the U3 slice is Task +105/− + a 311-line test file = 417 > 400. Per
§2.6 (no budget bypass), the dispose boundary group is split into U4:
the task-end override reset (6 Task lines + 3 DTE JSDoc lines) and its
12-line describe("dispose") test block. This matches the plan's own U4 scope
line ("persistence + boundary cases"). U3 keeps the generic 4-line dispose()
JSDoc; U4 expands it with the DTE sentence alongside the reset code.

CR re-review amendment (2026-09-05, review 5120440807). The main-sync
head re-review requested the task-end override reset to live in
disposeOnce() of this unit (so a retained disposed task never serves a stale
override, and the dispose() JSDoc's "resets transient task-local state"
claim is accurate), plus the test afterEach teardown to call
await task.dispose() unconditionally (the !task.abort guard had skipped
disposal of aborted tasks). Both land here in commit 1edd728c4 (+5/−1 ⇒
standalone 398 → 403 — a 3-line overshoot of the soft target, within the 1000
hard cap). Under the split above, U4 loses the reset code it had carried; its
12-line dispose-boundary test block stays with U4 (it now exercises this
unit's reset on the stacked tree).

CR follow-up fix (2026-09-06, review thread comment 3942121231). The
re-review of head 1edd728c4 found that the unconditional field clears in
disposeOnce() left the override behind in apiConfiguration.reasoningEffort
and the built api handler — both are populated by
setRuntimeThinkingEffort, so a retained disposed task could still expose the
override through those copies. Commit 1087fcbd4 replaces the three
assignments with the standard clearing call this.setRuntimeThinkingEffort(undefined) —
which restores apiConfiguration/api from preOverrideReasoningEffort
(read before it is cleared) and then clears the runtime fields — and adds a
14-line describe("dispose") killing-test block asserting the clear and the
restore (Task.ts net +1; standalone 403 → 418 a+d — CR-driven, ≤1000 hard cap).

Provenance / fidelity

Task.ts: 3-way git merge-file — base 39bdfb188 (= 6ea45b36a^),
ours = U2 head, theirs = 90b47b053 (the last U3 commit, before the U4
persistence work). Zero conflicts. A whole-file extract was impossible:
the union's Task.ts carries U14-orchestrator and U4/U5 content
(215+/241− vs U1 head), and per-commit git apply --3way of the U3 patches
fails on upstream base drift.
Test file: byte-exact 90b47b053 version (311 lines) minus the dispose
describe (12 lines + separator), plus the 3 mutation-killing assertion
lines below = 301 lines; the header comment is trimmed to the U3 scope
("the task-end reset in dispose()" clause moves with U4).
U4 content excluded: taskMetadata.ts / history.ts persistence changes,
the describe("history persistence round-trip") and
describe("abortTask final save") blocks, and the HistoryItem import
(unused in the U3 slice).
src/eslint-suppressions.json: untouched. The union's +21 suppression-count
deltas vs the stack base are all in files owned by other units
(gemini-format.spec.ts 5→6, ask-queued-message-drain.spec.ts 18→32,
newTaskTool.spec.ts 26→31, new extension.ts 1) — none U3-owned.

Out of scope (next units)

U4 (DTE-2c): persist task thinking effort to history items,
taskMetadata merge propagation, and the task-end override reset split out
above (dispose boundary + its test).
U5 (DTE-2d): the Anthropic output_config.effort adaptive envelope.

Mutation-diff fix (killing assertions, plan L42 — same PR)

The first CI mutation-diff run (head d0b1a3dcd) reported 2 Survived
ConditionalExpression mutants — both on the two ternaries this unit
introduces:

Location	Surviving variant	Fix (this PR)
`setRuntimeThinkingEffort` source capture: `effort === undefined ? undefined : source`	replacement: false ⇒ always `source`: a label passed on a clearing call leaks into `source`	the clearing call now carries a label (`setRuntimeThinkingEffort(undefined, "stale-source")`); the existing `source: undefined` assertion then kills the variant
`getRuntimeThinkingEffortMetadata`: `effort !== undefined ? { reasoningEffort } : {}`	replacement: true ⇒ always `{ reasoningEffort: <maybe undefined> }`	key-absence assertion `not.toHaveProperty("reasoningEffort")` while unset — `toEqual({})` cannot kill it (toEqual ignores keys whose value is `undefined`); asserted pre-set and post-clear

The complementary variants (L1683-true, L1721-false) were already killed by
the existing toBe("test-source") and toEqual({ reasoningEffort: "high" })
assertions.

Local dev-stage gate (skill §5.1) on the latest CR-fix head 1087fcbd4:

📝 Summary

Summary by CodeRabbit

New Features
- Added an experimental Dynamic Thinking Effort setting, disabled by default.
- When enabled, models can adjust thinking effort for each step; manual chat controls remain available.
- Added temporary thinking-effort overrides that take precedence over configured values and remain active when API profiles change. Clearing an override restores the configured value.
Documentation
- Added localized setting names and descriptions across supported languages.
Tests
- Added coverage for the setting, override behavior, and visual settings displays.

Walkthrough

The PR adds the dynamicThinkingEffort experiment and transient task-local reasoning-effort overrides. It adds settings support and localization. It also changes Stryker test-selection flags for the extension package.

Changes

Dynamic thinking effort

Layer / File(s)	Summary
Experiment contracts and defaults `packages/types/src/experiment.ts`, `src/shared/experiments.ts`, `packages/types/src/__tests__/experiment.test.ts`, `src/shared/__tests__/experiments.spec.ts`	Adds the experiment ID and optional boolean schema field. Registers it as disabled by default and tests valid, invalid, enabled, and disabled states.
Reasoning effort resolution `src/api/index.ts`, `src/api/transform/reasoning.ts`, `src/api/transform/__tests__/dte-effective-reasoning-effort.spec.ts`	Adds transient request metadata, adaptive effort values, and precedence resolution from request override to settings value to model default.
Task-local runtime state and request propagation `src/core/task/Task.ts`, `src/core/task/__tests__/Task.runtime-thinking-effort.test.ts`	Stores task-local overrides, preserves them across profile changes, restores profile values when cleared, and adds active overrides to API request metadata. Disposal clears the override.
Experiment settings and localization `src/core/webview/__tests/`, `webview-ui/src/components/settings/__tests/`, `webview-ui/playwright/gallery/stories.tsx`, `webview-ui/src/i18n/locales/*/settings.json`	Adds webview state and settings-update coverage, UI interaction and visual tests, a gallery story, and localized setting labels.

Stryker Vitest discovery

Layer / File(s)	Summary
Extension mutation-test discovery `scripts/stryker-diff.mjs`, `scripts/stryker-diff.test.mjs`	Enables Vitest-related test selection, disables plugin-side related-test discovery, and updates manifest assertions.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~25 minutes

Change: Feature

Merge Risk: 🔵 Low · up to d47e9

Enabling the new experimental setting currently provides no per-step effort control. This is bounded to users who opt in, but the setting should be hidden or wired before merge.

Full details: Regression Evidence

Explanation

The Task tests do not cover the changed request-delivery behavior. Task.ts adds the override metadata to four request paths (lines 2593–2594, 5160–5161, 5412–5413, and 5583–5584), but Task.runtime-thinking-effort.test.ts only calls the private metadata helper directly (lines 288–299). Those tests would still pass if any or all four request-path spreads were removed. The other reported coverage includes state restoration and resolver branches, and the new durable settings UI has Playwright component snapshots for four themes.

Resolution

Add focused Task-level tests that exercise each of the four request paths and inspect the metadata received by the request consumer. Assert that an active override is delivered, and that the reasoningEffort field is absent after clearing the override. This will detect a missing or misplaced metadata spread at any request site.

Full details: Lifecycle Resource Cleanup

Explanation

The changed effort setter can leak VS Code LM configuration listeners. Task.setRuntimeThinkingEffort rebuilds the API handler on every activation, update, and clear (src/core/task/Task.ts:2417-2439). For a vscodeLm profile, buildApiHandler creates a VsCodeLmHandler (src/api/index.ts:214-215), whose constructor registers workspace.onDidChangeConfiguration and whose dispose() removes that listener (src/api/providers/vscode-lm.ts:735-754, 854-857). Task does not dispose replaced handlers. When an active override is cleared during disposeOnce, the changed code builds yet another handler (src/core/task/Task.ts:3506-3510), leaving its workspace listener registered after task disposal. Repeated effort changes or task disposal therefore provide a concrete trigger for listener leaks.

Resolution

Dispose the current API handler before replacing it in setRuntimeThinkingEffort and updateApiConfiguration, and ensure task disposal releases the final handler. Add a supported optional handler-disposal contract if required. Avoid rebuilding a handler merely to clear transient state during disposal, or dispose the newly rebuilt handler before teardown completes. Add a test that verifies the VS Code LM configuration listener is removed after override changes and task disposal.

Same shape as unit 1: adjacent additions on both sides, so both are kept. The gate entry keeps this unit's plugin-side related-test discovery and gains main's src/scripts/merge-lcov.mjs exclusion; the gate test keeps this unit's extension assertions plus main's types assertions and drops the pair that contradicts the entry. The two spec files had been cut mid-test by the conflict, so they are rebuilt complete: this unit's dynamic thinking effort round trip and main's blanket auto-deny round trip both survive, and the two SettingsView describe blocks are separate again. Local run: 44 gate tests pass via node --test. The two spec files cannot run in this worktree - the shared node_modules is a junction to another worktree and is missing posthog-node and @vitejs/plugin-react - so CI is the verifier for them; the resolution was checked structurally (no markers, both test sets present, balanced blocks). Suppression counts unchanged.

Main converted two mockContext.globalState.get casts to a typed reassignment, which earned a suppression reduction for this file. The conflict resolution kept the older cast form, so the file carried 198 violations against main's recorded 196 and compile failed. Restoring main's typed form brings the file back to 196 without touching eslint-suppressions.json. Counts: as-any 182 + typed any declarations 14 = 196, matching the recorded count.

The first resolution pasted the conflict blocks together, which cut tests mid-body and dropped main's code-index scope refactor. Rebuilt from the three stages (base, PR head, main) so both sides survive: - ClineProvider.spec.ts keeps this unit's dynamic thinking effort round trip AND main's blanket auto-deny round trip, and follows main's rename of the instance lookup to CodeIndexManagerRegistry plus the getCurrentWorkspaceCodeIndexScope provider mock, which is what the merged handler calls. - SettingsView.spec.tsx keeps both describe blocks instead of merging them into one. Explicit-any count for ClineProvider.spec.ts is 182, matching main, so the recorded suppression count (196 with the 14 typed any declarations) holds and no count was raised.

The conflict boundary fell between the last assertion of the dynamicThinkingEffort-unset test and its closing brace, so keeping both sides left the test open and eslint reported a parse error at the end of the file. Restoring the brace makes the file balance; both spec files now scan to depth zero.

One conflict: the SettingsView spec import block. Union of both sides - upstream widened the @roo-code/types import with `type ProviderSettings` and added the `ApiOptionsProps` type used by the shared ApiOptions mock, this branch keeps `experimentDefault`. All four imports are used in the merged file.

Rebased onto upstream/main (2baac5e5b) to clear a new conflict; your previous approval was on the pre-merge head, so it no longer applies. The merge touched only the conflicted files described in the merge commit.

The e2e-mock job failed at 7c98c57 in the [restart:verify] phase with 'Task should be present after restart'. The same phase passes at this same merge on Zoo-Code-Org#1521/Zoo-Code-Org#1522/Zoo-Code-Org#1528/Zoo-Code-Org#1311, so this re-runs the job before treating it as a real regression.

Hide dynamicThinkingEffort until its tool path exists.

The setting is visible because showInSettings defaults to true. The UI persists dynamicThinkingEffort: true, but no application code consumes this experiment, registers set_thinking_effort, or invokes Task.setRuntimeThinkingEffort with an effort value. Users can therefore enable a setting that provides no advertised per-step behavior.
