Tom Boucher bcc5a6d1ba fix(#1634): honor capability hook matcher and node-prefix command (#1638)
* fix(#1634): honor capability hook matcher and node-prefix command

Capability hook install (applyCapabilitySharedEdits) wrote each settings.json
hook entry with no `matcher`, so a tool-scoped hook fired on every tool (a
fail-closed guard could then block the whole session), and emitted a bare
single-quoted script path so a .js-family hook from a git/tarball source
without +x failed with Permission denied on every matching call.

- Pass through an optional declared `matcher` (entry-level sibling of `hooks`);
  absent => omitted (match-all), so existing shipped capabilities are unchanged.
- Validate `matcher` in the declaration (non-empty string, no control chars).
- Emit `node <quoted-path>` for .js/.cjs/.mjs hooks (mirrors first-party);
  .sh and others keep the bare quoted path (unchanged).

Root cause: the manifest hook schema (validator rule C4) was {event, script}
only with no matcher, and applyCapabilitySharedEdits never read or wrote one;
the command used shellSingleQuote(absScript) with no node prefix.

Regression tests fail-first on both defects (matcher dropped; bare path) and
pass after the fix; #1460 command assertions updated for the node prefix.

* chore(#1634): backfill changeset pr:1638

* fix(#1634): resolve lint and windows CI failures

- validator: replace the control-character range regex with a char-code loop.
  The literal /[\x00-\x1f\x7f]/ tripped ESLint's no-control-regex rule; char
  codes are equally precise and lint-clean. Behavior unchanged (still rejects
  matchers containing ASCII control characters incl. DEL).
- test: gate the executable-bit precondition on POSIX. Windows fs does not
  honor POSIX write modes (a 0o644 write reads back as 0o666), so the
  precondition is meaningless there and failed the windows-latest lane. The
  node-prefix assertion — the actual fix — is platform-independent and still
  runs everywhere.

* docs(#1634): amend ADR-894 for optional lifecycle hook matcher

The `role: "feature"` `hooks[]` entry now carries an optional `matcher`
(settings.json tool-scoping pattern: exact/pipe/wildcard/regex). Document
the field in the §2 schema table and record a Grilling-amendments entry:
the install path projects a declared matcher onto the emitted settings.json
hook entry (absent = match-all, so shipped capabilities are unchanged), and
per-runtime matcher projection (ADR-857 D8) stays a separate concern. This
amendment ships with the fix that introduced the field rather than as a
follow-up.

* docs(#1634): record WINDOWS-POSIX-MODE-BIT-ASSERT defect in CONTEXT.md

Capture the CI failure pattern from #1634/PR #1638 so it is not repeated: a
test that writes a file with a POSIX mode and then asserts statSync().mode
& 0o777 === <octal> passes on macOS/Linux but fails on windows-latest
(Windows fs does not honor POSIX write modes — reads back 0o666). Added as a
machine-greppable DEFECT predicate (symptom/examples/detect/fix-forward/
prevention) next to DEFECT.WINDOWS-TEST-PORTABILITY, with the fix-forward:
gate the mode-bit precondition on process.platform !== 'win32' and keep the
platform-independent behavioral assertion running everywhere.

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.
