Tom Boucher 36375513b9 feat(#3840): generate docs/FEATURES.md from per-feature fragments (#3845)
* feat(#3840): generate docs/FEATURES.md from per-feature fragments

docs/FEATURES.md was hand-maintained, and every feature PR wrote into two
shared mutable cells: the '### N.' heading whose integer was hand-allocated at
authoring time, and the hand-maintained table of contents. Concurrent PRs all
picked the same next integer, and two PRs adding differently numbered features
still collided on the TOC. #3831 was renumbered 165 -> 166 -> 167 -> 168 across
successive rebases, each collision also costing a full matrix verification run
because the sha-keyed pass marker dies with the rebase.

Mechanism: one fragment per feature at docs/features/<slug>.md carrying
id/title/group (and an optional order) in frontmatter, consolidated by
scripts/gen-features.cjs --write|--check into a marker-delimited region of
docs/FEATURES.md that holds BOTH the TOC and every section body. Group headings
and their order are derived too - a group sorts by its lowest-ordered member -
so there is no shared registry to edit either; optional per-group prose lives in
docs/features/_groups/<slug>.md. A contributor adds exactly one new file.
Wired into regen:derived and lint:generated-sync alongside the eight existing
generators, matching gen-adr-index.cjs's CLI shape and typed-REASON reporting.

Migration froze all 168 existing numbers verbatim: identical section set,
identical order, identical bodies. Two defects found in the tree are fixed
inline rather than carried forward - the '## Related' block had been spliced
into the middle of the document, orphaning §142's Reference line, and four
inbound anchors were already broken on next (FEATURES.md#runtime-identity in
two files, and #143-spec-phase-edge-completeness-probe off by one). Since the
repo has no link checker, --check now validates every inbound
FEATURES.md#anchor by resolved target, so that class cannot ship silently
again; locale FEATURES.md files resolve elsewhere and stay out of scope.

* fix(#3840): carry upstream §69 delta into its fragment and harden the generator

Review found section 69 missing '[--strict]' and REQ-STATE-05/06 versus
origin/next. Root cause was a stale base, not extraction loss: those lines
landed in 394bf384b (#3844) AFTER this branch forked at 63abcface, and
'git diff 63abcface origin/next -- docs/FEATURES.md' is exactly that hunk.
Merging origin/next auto-applied the hunk into the GENERATED region, which
--check immediately reported as stale; the delta is now carried in
docs/features/statemd-consistency-gates.md and regenerated from there.

--write is now fail-closed. It previously rendered the region even with
violations outstanding, warning only on stderr and exiting 0, so a
'--write && git commit' chain could commit a FEATURES.md carrying two
colliding sections. It now refuses and exits 1; --force is the explicit
override and says so in the report. The test that pinned the old behavior now
pins the refusal, plus the --force override and its scoping.

Marker forgery is rejected at two layers. A fragment body containing
'<!-- FEATURES:START' or '<!-- FEATURES:END' is a typed
body_forges_region_marker violation (fragments and group notes alike), and
spliceIntoFeatures anchors the end boundary with lastIndexOf instead of
indexOf, so a marker that reaches the document by any other route can only
make the generated region grow, never shrink. Matching is on marker PREFIXES,
so a decorated variant comment cannot slip past.

Symlinked corpus entries are refused with a typed dirent_not_regular_file
rather than read. A fork PR could otherwise commit docs/features/evil.md as a
symlink to any readable path and have the generator inline those bytes into
the committed docs/FEATURES.md on the next regen.

Equivalence re-verified with a method that cannot cancel out. The first
check extracted both operands with the same body-normalising helper, so
anything that helper dropped was dropped on both sides. The replacement runs
two independent passes: a global content-line multiset diff with no
per-section logic at all (0 gained, 19 lost, all 19 the stale hand-written
mini-TOC links this change deliberately deletes), and a per-section
byte-exact body diff carrying a coverage assertion that fails loudly per file
when the extractor accounts for fewer lines than the file contains. That
assertion caught two blind spots in the checker itself. 168/168 sections
present, order identical, one intended body difference (§142 regains the
Reference line orphaned by the misplaced '## Related' block).

title: Read-Only Planning Snapshot (`planning inspect`)
group: v1.7.0 Features
---
**Command:** `gsd-tools query planning inspect`
**Purpose:** Give downstream consumers — harness UIs, mission-control surfaces, dashboards, bots — one schema-versioned JSON document describing everything `.planning/` knows, so nothing outside gsd-core has to parse `ROADMAP.md` / `REQUIREMENTS.md` / `*-PLAN.md` / `*-SUMMARY.md` a second time. gsd-core is the single source of `.planning/` truth; a second parser is a second answer.
**Requirements:**
- REQ-INSP-01: `PLANNING_INSPECT_SCHEMA_VERSION = 1` is emitted as `schema_version`. Consumers MUST reject any other value rather than best-effort-parse an unknown shape.
- REQ-INSP-02: Read-only. The command mutates no planning state, and mutates nothing on disk, under any input.
- REQ-INSP-03: Unknown or conflicting evidence serializes as `null` / `"unknown"` with a coded entry in `diagnostics[]` — never inferred, reconciled, or defaulted. Every key is always present; a key is never omitted to signal absence.
- REQ-INSP-04: Argument errors fail loud (non-zero exit, typed `ERROR_REASON`); data gaps do not. v1 takes no arguments, and a stray positional or unknown flag is a usage error rather than a silently-ignored one.
- REQ-INSP-05: Roadmap acceptance, verification status, and UAT items are reported side by side per phase and are never folded into a single verdict. A ROADMAP checkbox carries `authoritative: false` — completion is derived from disk state.
- REQ-INSP-06: `accepted_phases` and `completed_plans` are independent fractions. `percent` is `null` whenever the scope is not `complete`, per the same rule the roadmap and progress surfaces follow.
- REQ-INSP-07: Payloads over ~50 KB use the existing `@file:` spill channel, resolved transparently before stdout.
**Why it does not simply serialize the internal snapshot.** `PlanningSnapshot` (the diagnostic-rule subject introduced by ADR-3180 §8.1) is deliberately additive and still growing — four fields at Phase 10, twenty-plus by Phase 12. Handing that shape to external consumers would freeze an internal contract by accident. `planning inspect` declares its own flat schema and maps into it, so a field added to `PlanningSnapshot` never changes what this command emits.
**Composed, never re-derived.** Milestone identity and phase enumeration arrive via `buildPlanningSnapshot`; completion from `isPhaseComplete` (disk-strict); live-plan counting from `scanPhasePlans`; the percentage arithmetic from `clampPercent`; STATE fields from `stateFieldValue`; plan bodies from the Plan Document Module; requirement IDs from `parseRequirements`; UAT items from `parseUatItems`. Markdown structure is read through the Markdown Sectionizer and Markdown Table Model seams, so the Traceability table is resolved by column name against its registered schema rather than by a position-anchored regex.
**Known limit — task-scoped file provenance.** A `<task>` declares the files it plans to touch, but `SUMMARY.md`'s `## Files Created/Modified` describes the whole plan. Spreading that list across a plan's tasks would be inference, so a task's `changed_files` is populated only where the summary attributes files to that specific task; otherwise it is `null` with `provenance: "plan_scoped"`. Closing this needs a change to the SUMMARY format, not to the reader.
