+## v5.8.0 — 2026-06-30 — offline gold-scored output eval (SKAL-1·4b)

+
+### Gold-scored output eval (SKAL-1·4b)
+
+- The review-coordinator self-eval gains its **scoring run**, building on the deterministic coordinator contract + golden corpus shipped as the 4a foundation in v5.7.0.
+- `lib/review/gold-scorer.mjs`: `scoreFindings(runFindings, goldFindings)` matches at **`(file, rule_key)` granularity** (line + severity deliberately ignored) → `{ tp, fp, fn, precision, recall, f1, matched, missed, spurious }`; `scoreVerdict` checks exact verdict match. Pure — no I/O, no LLM, no network. Vacuous-set conventions (empty run → recall 0; empty gold → precision 0; f1 collapses to 0) are documented in the module header.
+- `tests/fixtures/bakeoff-rich/runs/run-perfect.json`: the first **committed run** — reviewer payloads that, fed through `runContract`, reproduce all 5 seeded gold findings. The regression guard: any future contract change that silently suppresses or skips a seeded finding breaks the eval.
+- `tests/lib/gold-eval.test.mjs`: the **scoring run**, wired into `node --test`. Asserts `run-perfect` scores precision/recall/f1 = 1.0 and `verdict == expected_verdict` (BLOCK). Offline: committed payloads, no live agent spawn (the LLM-in-the-loop grading is the separate 4c tier).
+- **Third test-census category.** `lib/util/test-census.mjs` now reports a `goldEval` bucket (matched by `GOLD_EVAL_FILE_RE`) separately from `behavior` and `docPins` — a scoring run is neither behavior coverage nor a prose pin, so the honest-count invariant is a 3-way sum.
+- `docs/eval-corpus/README.md`: SKAL-1·4b moved from "Future hardening" to an implemented section documenting the scorer, run format, and census category.
+- Suite: **822 (820 pass / 0 fail / 2 skip)**, up from 809 (+10 scorer behavior tests, +3 eval scoring-run tests). The scorer test covers the discriminating paths (false negatives + false positives) and the degenerate empty-run / empty-gold cases, not merely the all-match case.
+- Version sync: `plugin.json`, `package.json`, `package-lock.json`, README badge, CHANGELOG top entry all at `5.8.0`, guarded by `doc-consistency.test.mjs`.

 A [Claude Code](https://docs.anthropic.com/en/docs/claude-code) plugin for deep implementation planning, multi-source research, autonomous execution, independent post-hoc review, and zero-friction multi-session resumption. Six commands, one pipeline:
 
-> **What's new — v5.7.1: leaner always-loaded agent listing (round 2).** The 17 example-bearing agents now keep their `<example>` blocks in the body (under `## When to use — examples`) instead of the `description:` frontmatter — voyage launches its agents by name, so the auto-selection examples were cost without function there. This trims ~3,180 always-loaded tokens (frontmatter `description` chars 17,672 → 4,945) from the agent listing injected into every session, with no behavior change. The saving lands after `/plugin marketplace update` + reload. **v5.7.0:** opt-in per-session token/cost metering (SKAL-2) + eval foundation (SKAL-1·4a). **v5.6.1:** one-line `description:` for the four reference/dormant agents (~700 tok). **v5.5.0:** brief **framing** enforcement (`brief_version 2.2`) + a `/trekreview` reviewer-schema contract. Additive — no breaking changes. **Full version history → [CHANGELOG.md](CHANGELOG.md).**
+> **What's new — v5.8.0: offline gold-scored output eval (SKAL-1·4b).** The review-coordinator self-eval gains a scoring run: `lib/review/gold-scorer.mjs` grades a committed agent-run fixture against the golden corpus at `(file, rule_key)` granularity (precision/recall/f1 + verdict match), and the suite census gains a third category (`goldEval`) so a scoring run is counted apart from behavior coverage and doc-pins. Offline + deterministic — committed reviewer payloads, no live agent spawn (the LLM-in-the-loop tier is the separate 4c).
