Add scripts/test-value-audit.mjs + scripts/lib/test-value-audit-lib.mjs: a heuristic that scores every test file under packages/*/src/**/__tests__/** and packages/dashboard/app/**/__tests__/** from git history, classifying commits as positive (fix+source co-change, Symptom Verification regressions, added-with-source) vs negative (flake/quarantine/timeout churn, test-only modifies, quarantine-ledger membership). Joins per-file durations from scripts/test-timings.json so SLOW + LOW-VALUE files rank first as deletion candidates. Emits docs/test-value-audit.json + docs/test-value-audit.md (top 40 + methodology + caveats). Pure scoring logic is unit-tested with synthetic commit records. The script never deletes tests — evidence only. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Test Value Audit
Generated by
scripts/test-value-audit.mjson 2026-06-26T00:03:00.110Z.This is a HEURISTIC, not ground truth. It is an evidence base for a human deletion decision. The script does not delete any tests. See Methodology + Caveats.
Summary
- Files analyzed: 2051
- With timing data: 1979
deletecandidates (valueScore ≤ 0 or quarantined): 288reviewcandidates (0 < valueScore ≤ 3): 839keep(valueScore > 3): 924- "Safe delete" under the deletion-ratchet (zero positive evidence + churn/quarantine): 54
- In quarantine ledger (current or historical): 59
Methodology
For every audited test file we run a single whole-history git log --name-status
pass and classify each commit that touched the file (renames followed backward):
Positive signal (encoded/caught a real bug):
fix(...)/fix:subject with a sibling source change in the same package (+3)fix(...)/fix:subject alone (+2)## Symptom Verificationregression marker in the commit body (+3, FN-5893)- test file first added together with source (+2), or added alone (+1)
- a plain test+source co-change modify (+1.5)
Negative signal (low value / churn):
- subject/body mentions
flake,flaky,deflake,quarantine,stabiliz,appease,timeout,retry(−3) - a modify that touched only the test file, no source (−1)
- appears in
scripts/lib/test-quarantine.jsonhistory (−5)
The per-file valueScore is the sum of commit weights (plus the quarantine penalty).
deletionPriority = durationMs / (1 + max(0, valueScore)) with a small boost for
net-negative files — so the ranking surfaces slow AND low-value files first
(most CI time saved per unit of lost signal). Recommendation: delete (≤0), review
(≤3), else keep.
Caveats (read before deleting anything)
- Heuristic, not truth. A quiet, never-modified test can still be load-bearing; a high-churn test can still be valuable. Use this to prioritize human review.
git log --follow/ rename limits. Renames are followed only through linearR/Cname-status chains; squash-merges collapse multi-commit history into one subject, so per-commit signal is lost for squashed work (this repo defaults to squash merges — a major reason to treat scores as lower bounds on value).- Subjects lie.
fix(...)is trusted as a positive even if the test was unrelated; conversely a real bug fixed under afeat(...)/FN-subject without source co-change may be undercounted. - Timing is a snapshot from
scripts/test-timings.json; files with no entry shown/aduration and get deletionPriority 0 (cost unknown, not necessarily cheap). - Not a green light. Deleting a gate test still requires the gate-eviction process (AGENTS.md). "Safe delete" only flags files that meet the ratchet's churn/quarantine bar.
