Tom Boucher 8249ebcf6e fix(#3770): require intentional RED evidence before GREEN (#4279)
* test(3770): add failing tests for intentional RED evidence gate

RED: classifyRedEvidence / buildRedEvidenceRecord / check tdd-red-evidence do
not exist yet; every row fails on require. Per #3770 only an intentional
target-test failure may authorize GREEN; zero-test discovery, fixture crashes,
unrelated failures, and unexpected green are INVALID_RED.

* fix(3770): require intentional RED evidence before GREEN

Only an intentional failure of the TARGET test (distinctly named, TAP-reported
assertion failure) classifies as RED_EVIDENCE_OK and authorizes GREEN. Zero-test
discovery, fixture/load crashes (file-named failures), nonzero exits without a
failing test, unrelated failures, unexpected greens, and malformed/missing
records are INVALID_RED and block GREEN.

- src/tdd-red-evidence.cts: pure classifier + persisted record builder (reuses
  the prohibition-enforcement TAP primitives; fail-closed, never throws)
- check tdd-red-evidence <record.json>: validates the persisted record
  (command, exit code, failing test, expected, actual)
- gsd-executor.md / references/tdd.md / references/execute-mvp-tdd.md: RED now
  requires the evidence record + gate verdict, not a nonzero exit or a RED: tag

* chore(3770): regenerate inventory manifest for tdd-red-evidence.cjs

* fix(3770): fit executor fail-fast under size cap, fix unrelated-failure fixture, ignore generated lib

- gsd-executor.md: compress the #3770 fail-fast rule to one line (49149 B <
  49152 cap; line-count parity keeps the #2751 PROSE_ALLOWLIST line 816 valid)
- tests: the row-6 fixture used String.replace (first-occurrence), so the
  `not ok` line still named the target test and the classifier was right to
  accept it; replaceAll makes the failure genuinely unrelated
- eslint.config.mjs: ignore tsc-generated bin/lib/tdd-red-evidence.cjs
  (lint the src/*.cts source, per ADR-457 migration rule)

Emitted-Drift-Ack-Growth: gsd-executor.md — the #3770 fail-fast rule now requires intentional RED evidence (check tdd-red-evidence) before GREEN; +172 bytes, kept under the LARGE cap and on one line

* chore(3770): add changeset

* chore(3770): backfill PR number in changeset

Changeset Fragments

This directory holds per-PR CHANGELOG fragments. Every PR with user-facing changes drops one (or more) <random-name>.md files here describing its CHANGELOG entry. Fragments are consolidated into the top-level CHANGELOG.md at release time.

Why

Two PRs that both edit the ### Fixed block of CHANGELOG.md always conflict on merge — git can't pick a serialization order without human input. Two PRs that each add a fresh .changeset/<unique-name>.md never conflict because they don't share lines.

See #2975 for the full rationale.

Adding a fragment

node scripts/changeset/new.cjs \
  --type Fixed \
  --pr 1234 \
  --body "fix the thing — explain the user-visible change in one sentence"

This writes .changeset/<adjective>-<noun>-<noun>.md with frontmatter and a body. Three random words → concurrent PRs don't collide.

Format

---
type: Fixed
pr: 1234
---
**`/gsd-foo` no longer drops trailing slashes** — explain the user-visible change.

Allowed type: values follow Keep a Changelog: Added, Changed, Deprecated, Removed, Fixed, Security.

Opting out

PRs that legitimately have no user-facing impact can add the no-changelog label. CI honors it. When unsure, add the fragment.

At release time

Promotion is automatic. The release workflow's finalize job runs:

node scripts/changeset/cli.cjs render --version vX.Y.Z --date YYYY-MM-DD --allow-empty

This reads every fragment, groups bullets by type:, replaces ## [Unreleased] with a new ## [vX.Y.Z] - YYYY-MM-DD block, opens a fresh ## [Unreleased] above, and deletes consumed fragments. The --allow-empty flag ensures a no-change release still gets a dated heading (with a _No notable changes._ placeholder). A subsequent verify step confirms the promotion landed correctly. Maintainers do not run this by hand.

Archived fragments

.changeset/archived/ holds fragments for already-shipped releases (≤ 1.3.1), retained for provenance. Their content was hand-curated into the dated ## [1.x.y] sections of CHANGELOG.md during the #690 backfill — they were never consumed by render. All changeset tooling enumerates .changeset/ non-recursively, so archived fragments are never picked up or rendered. Do not move them back to the top level.
