## Summary
- Files analyzed: **2051**
- With timing data: **1979**
- `delete` candidates (valueScore ≤ 0 or quarantined): **288**
- `review` candidates (0 < valueScore ≤ 3): **839**
- `keep` (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 Verification` regression 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.json` history (−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 linear
`R`/`C` name-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 a `feat(...)`/`FN-` subject without source co-change
may be undercounted.
- **Timing is a snapshot** from `scripts/test-timings.json`; files with no entry show
`n/a` duration 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.

### One-line recommendations
1. `packages/engine/src/__tests__/workspace-merger-idempotency.test.ts` — **delete**: no positive (bug-encoding) signal in history; pure churn — strong delete candidate (slow: 12.7s — high CI time payoff)
