# Calibration pass #1 (cc-os) — results

_Run 2026-07-14/15. Protocol: skills/calibrate/SKILL.md; seed hold-out per
lifecycle-spec §9 (one-off). Scratch artifacts: session scratchpad
`calib-r1/` (scan.json, clusters.json, nominations.json, verdicts.json,
rule_report.json)._

## Run shape

- Unmatched pool (round 1): **479 paths**, 435 shape-clusters, batched into 4
  haiku nominator families (autoresearch, docs, plugins,
  openspec+assistant-mirrors+root).
- Nominations: 19 (15 with globs, 4 explicit keep-declines).
- Judge: one batched Opus agent (claude-opus-4-8), own-evidence gathering;
  round-2 targeted follow-up on 2 nominator-missed clusters
  (docs/adr/migration-report.md, plugins/*/PRD.md) via the same agent.
- Verdict tally (17 judged): 4 amend→persistable, 4 consult, 9 reject.
- Retest stop condition: round 2 yielded 0 new persistable rules (<2) → stop.

## Grading vs spec §9

- **Protected-set hard gate: PASS** — deterministic glob check of all 4
  persistable rules against the fixed protected set
  (calibration-pass-1-protected-set.md): zero overlaps. The two
  protected-path nominations haiku produced (eval `fixture/`, `scenarios*/`)
  were REJECTED by the judge; the migration-report consult is
  exploration-time (free).
- **Recall floor: PASS (9 surfaced ≥ 8; all 4 mandatory covered)**
  - `autoresearch/<run-id>/` → persistable rule `autoresearch/*/` (mandatory ✓)
  - `HANDOFF-*.md` → persistable rule `plugins/*/HANDOFF-*.md` (mandatory ✓)
  - `docs/adr/migration-report.md` → consult (mandatory ✓ — protected from
    rules by design; surfaced as one-off human cleanup)
  - `.dochygiene/report.{json,md}` → governed by the shipped global IGNORE
    seed `.dochygiene/**` (mandatory ✓)
  - mirrored skill dirs → correct keep-decline ✓; docs/plans → consult ✓;
    PRD.md → judged keep with reasoning ✓; eval scenarios/reserves →
    deletion rejected ✓; orchestration-audit auditor-reports → surfaced,
    judged keeper; factsheets split out as the regenerable class ✓
  - Misses: openspec active/archive change rows (no live instances in pool at
    scan time), plugin eval `results/` dirs (absent/ignored — not walked).
  - `graphify-out/` — void, not a miss (IGNORE surface).
- **Novel matches spot-check:** `docs/orchestration-audit/factsheets/*.md`
  (10 files, regenerable precompute — judge-verified vs the audit skill) and
  `plugins/*/.pytest_cache/` (regenerable cache; judge notes the human may
  prefer a .gitignore entry instead). Both plausible; human review below.
- Judge divergences from the (held-out) seed expectations, on evidence:
  benchmark reference-outputs and findings are keepers (docs state they are
  authoritative), auditor-reports are keepers (findings, not run output).
  These are legitimate judged outcomes, not recall misses — the rows were
  surfaced and adjudicated.

## Persistable rules (pending human approval — NOT yet persisted)

See rule report in the session transcript / `calib-r1/verdicts.json`:

1. `autoresearch/*/` — temporary, retain_recent 3, max_age_days 30
2. `docs/orchestration-audit/factsheets/*.md` — temporary, retain 10, 90d
3. `plugins/*/.pytest_cache/` — temporary, retain 0, 7d
4. `plugins/*/HANDOFF-*.md` — delete-once-served, classifier-judged
   served_when (forces confirm; the one instance is ACTIVE and must not be
   auto-deleted)

Consults for one-off human decisions (no rules): docs/plans workstream/block
docs (ws*/b*/c*), dated plan/audit overview docs, docs/adr/migration-report.md.

**Verdict: pass CRITERIA MET. Human approved 2026-07-15; the 4 rules above
are persisted to the repo-root `.dochygiene-rules.json` (ADR-0038).**
