Fix/shared dev metrics - #52
Conversation
record-run.mjs, record-eval-run.mjs and metrics-report.mjs each resolved .dev-metrics/runs.jsonl relative to the current checkout, so every worktree got its own copy and pruning worktrees deleted all recorded runs. They now share one resolveMetricsFile() helper (scripts/metrics-path.mjs) that points at <git-common-dir>/opendrs-dev-metrics/runs.jsonl by default, overridable with OPENDRS_METRICS_FILE, falling back to the old path when git is unavailable. Also: record each entry's worktree path so per-branch timings stay distinguishable in the shared file, and add a metrics-report.mjs section flagging kinds whose median duration exceeds a threshold (default 10 min, --slow-threshold-min to override) as parallelism candidates. No old .dev-metrics/runs.jsonl existed anywhere in this clone or its worktrees to merge. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
vitest.config.ts only includes tests/**/*.test.ts, so the scripts/*.test.mjs files added for metrics-path.mjs and metrics-report.mjs never ran in `npm test` or CI. Move them to tests/scripts/*.test.ts (vitest describe/it, same convention as tests/domain, tests/model, etc.) and add sibling .d.mts declaration files for the two .mjs modules so tsc --noEmit can type-check the imports without turning on allowJs project-wide.

Explanation
The title "Fix/shared dev metrics" matches the main change: dev-loop metrics storage moves to a shared resolver under the Git common directory, with OPENDRS_METRICS_FILE override and fallback, plus related report and test changes. It is brief, but it names the primary subject. It uses a branch-style "Fix/" prefix and the vague word "Fix" does not say what was fixed, so the title is only partially specific.

Explanation
The description contains only the template headings and unchecked checklist items. It has no text under "What and why" that explains the shared metrics resolver, the Git common directory storage, the OPENDRS_METRICS_FILE override, the worktree field, or the new parallelism-candidates report. The "How it was tested" section lists no results, and the checklist items remain unchecked. The PR objectives state that no test results are checked or reported. The description is therefore largely incomplete.
Resolution
Add a "What and why" section that explains the shared metrics ledger, the resolution order (OPENDRS_METRICS_FILE, then the Git common directory, then .dev-metrics/runs.jsonl), the new worktree field, the computeSlowKinds report and its --slow-threshold-min option, and the move of the metrics tests under tests/. Under "How it was tested", state which checks were run and their results, and check the boxes that apply. Confirm whether src/ changed, because this decides whether npm run build:action and action/dist apply. Confirm whether docs/specs applies. The changed files suggest src/ and docs/specs may not be affected, so mark those items as not applicable.

⚠️ Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.Calculate the maximum without spreading the full group.
The shared ledger is append-only. If a slow kind accumulates more durations than V8 accepts as function arguments,
Math.max(...durations)throws and the report prints no results. CalculatemaxMswith a loop or reduction so report availability does not depend on the group’s argument count. V8 enforces an argument-count limit. (chromium.googlesource.com)

whose `durationMs` is null or otherwise unmeasured from both the median and
measured count. Skip reporting any kind with no measured durations, while

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Exclude runs without a measured duration from the median.
scripts/record-eval-run.mjs writes durationMs: null when the aggregate has no numeric durationSeconds. This fallback counts each such run as zero. One 20-minute eval and two evals without durations therefore produce a zero-minute median, so the report omits a slow kind. Include only measured durations in the median and measured count; skip kinds with no measured durations.
