# Doc Review: harden-parse-verdict

## Docs touched

- `design/loops/technical.md` §7 — tick-flow step 7 (parse verdict):
  added 4-line inline block documenting the defensive coercion (pass
  string acceptance; score clamp + NaN/inf/non-numeric → 0.5).
- `design/loops/functional.md` §10 — Verifier Contract: annotated
  `pass` (bool) definitive + runner accepts `"true"`/`"false"` strings;
  annotated `score` (0.0–1.0) clamp + NaN/inf/non-numeric → 0.5 neutral.
- `CHANGELOG.md` — new `[unreleased]` "Fixed — `parse_verdict`
  defensive coercion" block above the existing `add-state-loop-lock` and
  `fix-harness-command-template` blocks.

## Docs NOT touched (intentional)

- `AGENTS.md`: parse_verdict is not a user-visible CLI surface; the
  hardening doesn't change phase enforcement, `.state.loop`, or any
  contract that harness integrators need to know. The Verifier Contract
  lives in `design/loops/functional.md` §10; AGENTS.md already points to
  design docs at the top. No edit.
- `README.md`: user-facing README doesn't enumerate `parse_verdict`
  internals; loop monitoring table mentions verdicts as a concept, not
  the parser. No edit.
- `prompts/loop-verifier.md`: contract was already `bool pass` + `score
  0.0–1.0`. The hardening is belt-and-suspenders against malformed
  output, not a contract change. The prompt's strict-JSON directive
  stays authoritative. No edit.
- `templates/loops/self-improvement/loop.json`: no schema change. No
  edit.

## Cross-references

- `tasks/add-loop-runner/BUG_REPORT.md` O6 — the original finding —
  now closed by this task. The CHANGELOG entry explicitly references it.
- `tasks/add-loop-runner/ADVERSARIAL_BUG_REPORT.md` A6 — the score-
  clamping observation — also closed by this task. The CHANGELOG entry
  references the clamping.
- `tasks/harden-parse-verdict/BUG_REPORT.md` O3 — notes that clamping
  improves plateau detection (a tighter `score_history` range makes
  plateau more honest). Cross-referenced from the CHANGELOG.

## Verdict

Docs are in sync with the implementation. Proceed to referee.
