- formatBriefTimestamp (5): force LC_ALL=en-US + TZ=UTC for CI
- EFFORT_LEVELS (1): update to 5 levels (added xhigh)
- effort description (1): remove stale 'no model names' test
- prompt caching (1): fix input_tokens expectation to match
Anthropic convention (non-cached only)
- ExecuteTool: rename runner to .runner.test.ts so bun finds it
- localVault/store.ts: synced from upstream
Remaining 4 failures are test isolation issues (compound command)
and feature flag mismatch (CtxInspectTool) — all pass in isolation.
