The B15 usage-capture cherry-pick was authored against an older base and reverted newer upstream/base behavior in several files, causing e2e-mock subtask timeouts (7 tests) and unit-test failures. Restore clobbered base behavior while keeping B15's genuine usage/cost capture additions: - Task.ts: restore run() + _runPromise/_isHistoryTask, safeEnsureModelFetched (def + 3 call sites), abort-aware ask wait, resume_completed_task via initialStatus, and t() i18n in sayAndCreateMissingParamError. - ClineProvider.ts: scheduler gates on task.run() (completion promise) instead of fire-and-forget task.start(). This is the root cause of the subtask/resume e2e timeouts. - openai-codex.ts: restore service-tier feature alongside cost capture. - moonshot.ts, vscode-lm.ts, vscode-lm-format.ts, eslint-suppressions.json: revert to base (pure clobber, no genuine B15 content). - task-run-dispatch.spec.ts: bind run() (not start()). - openai-usage-tracking.spec.ts: assert totalCost from cost capture.

This script writes as any into a TypeScript spec file, which the coding guidelines prohibit.
Line 24 replaces Record<string, never> with Record<string, unknown>. Line 56 then replaces that exact string with as any, so line 24 has no net effect. The result is as any in src/api/transform/__tests__/vscode-lm-format.spec.ts.
The comments at lines 49-51 acknowledge the guideline and then override it. Replace the casts with as unknown as <SpecificType> at each site, or keep a double assertion and document the reason in a comment next to it.
Line 56 is also over-broad. It rewrites every as unknown as Record<string, unknown> in the file, not only the strings that line 24 produced.
As per coding guidelines: "Avoid as any; use typed APIs, bracket notation for private members where appropriate, or precise test doubles and unknown with type guards" and "Fix lint violations in new JavaScript and TypeScript code instead of suppressing them."

Remove these single-use migration scripts from the PR.
All eight scripts are one-shot utilities with hardcoded target paths, hardcoded branch refs, and hardcoded replacement text. Their output is already committed in the TypeScript files they edited, so re-running them is either a no-op or destructive. None of them accept arguments, and none are referenced by the build or by CI.
Two of the sets are self-cancelling chains that record a trial-and-error process rather than a result. fix_b15_types7.py and fix_b15_types8.py each apply a replacement and then immediately reverse it. fix_mock_cast.py, fix_mock_cast2.py, and fix_mock_cast3.py form a three-step sequence in which step 2 repairs corruption that step 1 introduced. The inline comments in fix_b15_types7.py and resolve_b05_test_conflicts.py also contain unresolved deliberation, which does not belong in committed code.
The PR objectives state that a follow-up commit already removed internal report files. Apply the same treatment here. If any script has lasting value, move it behind argparse with validated paths, add a test, and document it. Otherwise delete it.

The script mass-inserts undocumented lint suppressions, which the coding guidelines prohibit.
Line 26 and line 43 cancel each other, so neither changes the file. The remaining effect is the loop at lines 46-61, which inserts // eslint-disable-next-line @typescript-eslint/no-explicit-any`` above every line that contains as any. Each inserted suppression carries no justification.
Two further problems:
- Line 49 uses a plain substring test. It matches
as anyinside string literals and inside trailing comments, so it can insert a suppression above a line that needs none. - Line 51 reads
lines[i-1]from the original list while the loop appends tonew_lines. The duplicate check therefore inspects pre-insertion state, not the output being built.
Fix the underlying cast types in the spec file instead. If a suppression is unavoidable, add the reason next to it.
As per coding guidelines: "Fix lint violations in new JavaScript and TypeScript code instead of suppressing them" and "If a lint suppression is unavoidable, document the reason in a comment next to the cast or suppression."

Recompute segmentPath after segment rotation.
Line 431 resolves segmentPath from manifest.currentSegment before the rotation check. When rotation occurs at line 446, the code increments manifest.currentSegment and persists the manifest, but it still appends the event to the previous, already-full segment. The rotation therefore takes effect one event late, and the segment exceeds SEGMENT_MAX_BYTES. The error message at line 468 also reports the new segment number while the write targeted the old file.

Accept an append port instead of the concrete UsageEventStore.
The constructor requires a UsageEventStore. The caller in src/core/task/Task.ts therefore writes new UsageRecorder(service as unknown as UsageEventStore, ...), a double assertion that hides a real type mismatch: it passes a UsageStatsService, not a store. The class doc at line 53 already states the hexagonal boundary intent. Declare the minimal port so the cast disappears.

A storage failure permanently discards the event.
Line 86 adds idempotencyKey to finalizedKeys before the append. The catch block at line 129 swallows every store error. If append throws, for example with STATS_STORE/append/002 after a lock timeout, the recorder has already marked the key as finalized. A later call with the same requestKey and status returns at line 84, so the attempt is never recorded. Mark the key only after append resolves.
🐛 Proposed fix
const idempotencyKey = `${requestKey}:${status}`
if (this.finalizedKeys.has(idempotencyKey)) {
return

}Note: UsageEventStore.append is idempotent by idempotencyKey, so a retry after a partial failure cannot create a duplicate within the same process.

The event omits endpoint and rootTaskId.
UsageRecordingContext declares endpoint at line 40, and UsageEventV1 in packages/types/src/usage-stats.ts adds both endpoint (line 62) and rootTaskId (line 51). This event literal sets neither. Every recorded event therefore lacks the endpoint domain and the root-session identity. The schema doc states that rootTaskId is "Resolved from the task hierarchy by the recorder", so this producer is the intended source. Dashboard streaming that groups by rootTaskId receives no value.
