+**Decision-coverage gate now reads markdown-header and em-dash decisions, and fails loud when it can't parse them** — `check.decision-coverage-plan` (a blocking gate) and `gap-analysis` previously extracted **zero** decisions from a populated CONTEXT.md that recorded its decisions under markdown headers (`## Locked decisions`) or with em-dash bullets (`- **D-1 — title**`), and silently reported a clean pass — so real decisions went un-checked. Decisions in those shapes are now recognized, and when decision-shaped content cannot be parsed (or a `- **D-NN**` bullet is malformed), the gate fails loud with a format-mismatch message instead of passing.

### I/O Module
Module owning the tool's CLI I/O primitives: `output()` result emission (with large-payload temp-file spillover via `GSD_TEMP_DIR`/`ensureGsdTempDir`/`reapStaleTempFiles`), `error()` stderr emission with exit-code mapping, and the JSON-error-mode toggle (`setJsonErrorMode`/`getJsonErrorMode`, `ERROR_REASON`). Extracted from the Core module per ADR-857 rollout phase 1 (#859) so feature modules (`graphify`, `intel`, `audit`, `profile-pipeline`) depend on a small I/O seam instead of the core god-module; the `core.cjs` re-export spine was retired in epic #1267, so callers import this leaf directly. Source of truth: `gsd-core/bin/lib/io.cjs` (generated from `src/io.cts`).
+### Markdown Sectionizer
+Canonical markdown-structure parsing seam (`gsd-core/bin/lib/markdown-sectionizer.cjs`, generated from `src/markdown-sectionizer.cts`). Pure functions, Node built-ins only. Exports: `stripFencedCode(content) → { text, unterminatedFence }` (CommonMark-correct state machine, CRLF-safe, signals unterminated fences); `tokenizeHeadings(content) → HeadingToken[]` (ATX headings outside fenced blocks, `{ level, text, line, offset }`); `collectSections(content, stopPredicate) → Section[]` (line-by-line section collection driven by a heading predicate); `collectSection(content, headingPredicate, { levelBounded, stripFences }) → Section | null` (single named section with level-bounded stop); `iterateBullets(sectionText) → BulletItem[]` (dash/checkbox/numbered markers with indented continuation); `extractTaggedBlocks(content, tagName) → string[]` (inner text of every `…` block in document order, tagName regex-escaped, caller decides fence-stripping — generalises `decisions.cts`'s bespoke extractor for T1); `replaceSection(content, section, newBody) → string` (pure character-offset splice using `Section.bodyStart`/`bodyEnd` for read-modify-write callers — eliminates T6 `state.cts`'s 7× inline `content.replace` pattern). `Section` carries `bodyStart`/`bodyEnd` offsets for `replaceSection`. ADR-1372 (epic #1372) establishes this seam and a tiered migration plan (T0–T7) to retire the 8+ ad-hoc markdown parsers and ~20 inline section-collects across `src/*.cts`. New `src/*.cts` modules must import this seam instead of hand-rolling fence strippers or heading-regex section walks (enforced by the `no-adhoc-markdown-parsing` ESLint rule landing in tier T7).

### Roadmap Parser Module
Module owning ROADMAP.md parsing: shipped-milestone slicing, current-milestone extraction, milestone/phase lookups, and milestone-phase filtering (`stripShippedMilestones`, `extractCurrentMilestone`, `replaceInCurrentMilestone`, `getRoadmapPhaseInternal`, `getMilestoneInfo`, `getMilestonePhaseFilter`). Depends only on leaf modules (`phase-id`, `planning-workspace`, `shell-command-projection`) — no `loadConfig`, no other core dependency. Extracted from the Core module per ADR-857 rollout phase 2b (#870), resolving the ROADMAP.md parse/write straddle so the Roadmap module (`roadmap.cjs`, which owns ROADMAP.md mutation) imports parsing directly instead of through Core; the `core.cjs` re-export spine was retired in epic #1267, so callers import this leaf directly.

+- **Pattern precedent:** [ADR-857](857-capability-system.md) / epic [#1267](https://github.com/open-gsd/gsd-core/issues/1267) (retire a duplicated spine via tiered children)
+
+## Context
+
+GSD parses a lot of structured markdown — `CONTEXT.md`, `ROADMAP.md`, `STATE.md`, `*-PLAN.md`, UAT files, ADRs, frontmatter. There is **no shared primitive** for the three operations every one of these parsers needs (strip fenced code, tokenize headings into sections, iterate bullets), so each module hand-rolls them. A grounded map of `src/*.cts` found:
+
+- **8+ independent markdown parsers**: `decisions`, `gap-checker`, `roadmap-parser`, `state`, `uat`, `uat-predicate`, `adr-parser`, `check-command-router`.
+- **3–4 independent fenced-code strippers of different fidelity**: `decisions.cts` (fragile regex, no unclosed-fence handling), `roadmap-parser.cts` `stripFencedLines` (state machine, **duplicated 3× in one file**), `uat-predicate.cts` `_stripFencedBlocks` (CommonMark-correct, CRLF-safe, signals an unterminated fence), `check-command-router.cts` `stripCommentsAndFences` (another regex copy).
+- **~20 hand-rolled section-collects**, with `state.cts` alone re-implementing the same `/(###?\s*\s*\n)([\s\S]*?)(?=\n###?|$)/i` shape **13 times**.
+
+The consequence is a recurring maintenance game: every "the parser missed structure X" report (#1343 bullet-before-colon, #1364 markdown-header + em-dash, #1324 glued phase tokens, #447 gap scoping) is fixed *locally* with another regex, and the same class of bug re-opens in the next parser. The fixes do not compound — they accrete. Worse, in the decision-coverage case the failure mode is **silent**: a blocking gate that cannot parse its input reports `passed:true, covered 0/0` and ships the phase with its decisions unchecked.
+
+There are two root causes, and a durable fix must address both:
+
+1. **No canonical structure primitive** — so structural correctness (fences, CRLF, heading levels, Unicode, bullet shapes) is re-litigated per module and tested unevenly.
+2. **Nothing prevents the next ad-hoc parser** — a new PR can add a fourth fence stripper and no gate objects, so the divergence regrows even after a cleanup.
+
+## Decision
+
+Establish a single canonical markdown-structure seam and make ad-hoc markdown scanning a lint-enforced prohibition. Migrate every existing parser onto the seam incrementally, tracked as tiered children of epic #1372.
+
+### 1. The seam — `src/markdown-sectionizer.cts` (pure, Node built-ins only)
+
+No external markdown library (the "no external dependencies in core" rule stands). Pure functions, string-in → value-out, no I/O:
+
+- `stripFencedCode(content) → { text, unterminatedFence }` — the CommonMark-correct state machine promoted from `uat-predicate.cts` `_stripFencedBlocks` (CRLF-safe; ≤3-space indent tolerated; closes only on a same-or-longer fence run). `unterminatedFence` is a reusable malformed-input diagnostic.
+- `tokenizeHeadings(content) → HeadingToken[]` — ATX headings `{ level, text, line, offset }` in document order.
+- `collectSections(content, stopPredicate)` and `collectSection(content, headingPredicate, { levelBounded, stripFences })` — line-by-line (not greedy-regex) section collection; `levelBounded` encodes the dominant "stop at same-or-higher-level heading" pattern. Both populate `bodyStart`/`bodyEnd` character offsets on the returned `Section` for use by `replaceSection`.
+- `iterateBullets(sectionText) → BulletItem[]` — dash/asterisk/plus, checkbox (`- [ ]`/`- [x]`), and numbered markers, with indented continuation-line accumulation.
+- `extractTaggedBlocks(content, tagName) → string[]` — returns the inner text of every `…` block in document order; `tagName` is regex-escaped; the caller decides ordering (does not strip fences). Generalises `decisions.cts`'s bespoke `` extractor for T1 adoption.
+- `replaceSection(content, section, newBody) → string` — pure character-offset splice using `section.bodyStart`/`bodyEnd`; replaces a section body in a read-modify-write workflow (e.g. `state.cts`'s 7× inline `content.replace(/(##\s*Name\s*\n)([\s\S]*?)(?=\n##|$)/, ...)` pattern). CRLF-safe.
+
+The seam is fully tested against the parser QA matrix (CRLF, Unicode headings, headings-inside-fences, unterminated fences, nested levels, malformed bullets) **once**, so every adopter inherits that correctness instead of re-deriving it.
+
+### 2. Prohibition + enforcement — `local/no-adhoc-markdown-parsing`
+
+A new ESLint rule in `eslint-rules/no-adhoc-markdown-parsing.cjs` (wired in `eslint.config.mjs`, mirroring `local/no-source-grep`) flags new hand-rolled markdown-structure scanning outside the seam — fenced-code strip regexes, `split(/\r?\n/)` + heading-regex section walks, and `D-`/checkbox bullet regexes — in `src/*.cts`. Existing sites are **grandfathered** by an explicit allowlist that is burned down as each tier migrates (the same grandfathering pattern `no-source-grep` uses). New code must import the seam. This is the part that stops the game permanently: after this rule lands, a PR cannot introduce a fourth fence stripper without a reviewer-visible failure.
+
+### 3. Decisions realization (tier T1) — typed result + fail-loud gate
+
+The first behavioral adopter, which also resolves the two open bugs. `decisions.cts` is rewritten onto the seam, and a typed result distinguishes the states the blocking gate cares about:
+
+```
+type DecisionExtraction = {
+ decisions: Decision[];
+ outcome: 'parsed' | 'none-present' | 'could-not-parse';
+};
+```
+
+`parseDecisions(content): Decision[]` is preserved as a thin delegate (consumers untouched); `extractDecisions(content): DecisionExtraction` is the typed entry point. `cmdDecisionCoveragePlan` (blocking) treats `could-not-parse` — content is decision-shaped (a `` block, a `/decisions?/i` heading, `\bD-` tokens, or `unterminatedFence`) yet 0 decisions extracted — as a **WARN/fail** ("could not parse decisions — possible format mismatch") instead of a green pass (**resolves #1365**). Routing through the seam recognises the markdown-header + em-dash variants (**resolves #1364**). Recall-first by design: a false "could-not-parse" is a loud warning a human clears; a false "none-present" is the silent bypass we are deleting.
+
+### 4. Migration tiers (epic #1372 children)
+
+Each tier is its own issue + PR (issue-first; one concern per PR), behaviour-preserving except T1, each separately tested, each burning down the `no-adhoc-markdown-parsing` grandfather list for the files it touches.
+
+| Tier | Scope | Risk | Notes |
+|---|---|---|---|
+| **T0** | Seam foundation: `markdown-sectionizer.cts` + QA-matrix tests | none | No migration, no behavior change. Foundational. |
+| **T1** | `decisions.cts` + coverage gate: adopt seam, typed result, fail-loud | low–med | **Resolves #1364, #1365.** First behavioral adopter. |
+| **T2** | `adr-parser.cts`: `parseSections`/`splitEntries` → seam | none | CLI-only, no in-process callers — the safe prototype; its `parseSections` is the API shape the seam generalizes. |
+| **T3** | `check-command-router.cts` + `gap-checker.cts`: dedupe `stripCommentsAndFences`, designated-section walk, requirements bullets | low | Gate-adjacent; covered by existing gate tests. |
+| **T4** | `roadmap-parser.cts`: collapse the 3× inline fence loop + `computeSectionEnd` | med | Heavily tested; watch milestone-section boundaries. |
+| **T5** | `uat.cts` + `uat-predicate.cts`: donate the canonical stripper, migrate heading/section scans | med | `_stripFencedBlocks` becomes the seam's source in T0; T5 removes the local copy. |
+| **T6** | `state.cts`: 13 inline section-collects → `collectSection` | high | Highest payoff, highest risk — load-bearing for STATE.md mutation. Surgical, full regression, last. |
+| **T7** | Enforcement: `no-adhoc-markdown-parsing` ESLint rule + grandfather burn-down | low | Lands once enough tiers are migrated that the grandfather list is small; thereafter new ad-hoc parsing is blocked. |
+
+`frontmatter.cts` stays as-is — YAML frontmatter is a different grammar with its own well-used shared parser (`extractFrontmatter`); it is out of scope.
+
+## Backward compatibility
+
+No user-facing or authoring change. Behaviour-preserving migrations (T2–T6) keep each parser's outputs byte-identical (verified by each parser's existing tests + added characterization tests). T1 is the only behavior change: additive decision recall + the could-not-parse WARN; the `` block stays canonical and parses identically (block presence still takes precedence). Internal API churn is contained per-tier; public CLI contracts are unchanged.
+
+## Consequences
+
+**Positive:** structural correctness (fences/CRLF/levels/bullets) is solved and tested once; the silent fail-open class is eliminated for the blocking gate; the per-module regex pile stops growing *and* is prohibited from regrowing; future markdown parsers inherit correctness for free; the change models the repo's own typed-IR / no-source-grep philosophy. Retires 3–4 duplicate strippers and ~20 inline section-collects.
+
+**Negative / risks:** a large surface migrated incrementally — mitigated by tiering (zero-risk T2 prototype first, high-risk `state.cts` last, behavior-preserving with characterization tests, the epic visible end-to-end). A new shared module is a dependency for adopters — mitigated by purity + exhaustive tests. The recall-first "could-not-parse" heuristic may occasionally warn on decision-shaped-but-empty content — acceptable and tunable; a loud false alarm beats the silent miss it replaces. The enforcement rule (T7) must grandfather precisely to avoid blocking unrelated PRs mid-migration.
+
+## Alternatives considered
+
+- **Point-fix each parser bug as it's reported (status quo).** Rejected — this is the game we are ending; fixes accrete instead of compounding and the same class recurs in the next parser. The maintainer's explicit directive is a solution-wide structural fix, not another file edit.
+- **Consolidate the primitive but skip the enforcement rule.** Rejected — without the lint guard the divergence regrows; the next PR adds a fifth stripper and no gate objects. The prohibition is what makes the consolidation durable.
+- **External markdown library (remark/markdown-it/unified).** Rejected — "no external dependencies in core" is a hard rule.
+- **LLM / semantic extraction.** Rejected — `gsd-tools` is a deterministic, no-LLM, zero-dependency CLI with regression-tested pure `Result` functions; an LLM breaks the determinism/testability a CI gate requires and contradicts the repo's no-LLM precedent.
+- **One big-bang PR migrating every parser.** Rejected — `state.cts` alone is load-bearing and high-risk; a single PR would be unreviewable and unmergeable. Gall's Law: the working complex system is grown from a working simple seam (T0) plus incremental, individually-verified migrations.

+ * Exports: stripFencedCode, tokenizeHeadings, collectSections, collectSection,
+ * iterateBullets, extractTaggedBlocks, replaceSection
+ *
+ * Covers the parser QA matrix from CONTRIBUTING.md §'Parser and project-file inputs':
+ * - LF vs CRLF line endings
+ * - Unicode headings
+ * - Heading INSIDE a fenced block (must be ignored)
+ * - Unterminated fence (unterminatedFence === true)
+ * - Nested heading levels with level-bounded stop
+ * - All three bullet markers (dash/checkbox/numbered) + indented continuation lines
+ * - Empty/whitespace/non-string input
+ *
+ * Includes a fast-check property test (stripFencedCode idempotence invariant).
+ * Includes a parity guard for the tracked duplication between stripFencedCode
+ * and uat-predicate's _stripFencedBlocks (DEFECT.GENERATIVE-FIX — removed in T5).
