* refactor(#1373): add markdown-sectionizer seam (ADR-1372 T0) Establishes the canonical markdown-structure parsing seam per ADR-1372. No existing parsers are modified; this is the foundational T0 tier only. - docs/adr/1372-markdown-sectionizer-seam.md: Accepted ADR defining the seam interface, the tiered migration plan (T0-T7), and the prohibition enforcement approach (no-adhoc-markdown-parsing ESLint rule in T7). - src/markdown-sectionizer.cts: Pure module, Node built-ins only. Exports: stripFencedCode (CommonMark-correct state machine ported from uat-predicate.cts _stripFencedBlocks, CRLF-safe, unterminatedFence signal), tokenizeHeadings (ATX headings outside fenced blocks), collectSections (line-by-line predicate-driven section collection), collectSection (single named section, levelBounded stop, optional stripFences), iterateBullets (dash/checkbox/numbered + continuation). - tests/markdown-sectionizer.test.cjs: 54-test behavioral suite covering the parser QA matrix (LF/CRLF, Unicode headings, headings-inside-fences, unterminated fences, nested levels, all bullet markers, continuation lines, empty/non-string input) plus 4 fast-check property tests (idempotence, output shape, never-throws, length monotonicity). - CONTEXT.md: Markdown Sectionizer glossary entry added (PR review gate). Tests: 54 pass, 0 fail. Existing adr-parser + uat-passed tests: 22 pass. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * refactor(#1373): add extractTaggedBlocks + replaceSection to seam; register inventory - src/markdown-sectionizer.cts: extend Section type with bodyStart/bodyEnd offsets; add extractTaggedBlocks(content, tagName) (inner text of <tag>…</tag> blocks, tagName regex-escaped, caller decides fence-stripping) and replaceSection(content, section, newBody) (pure character-offset splice for read-modify-write callers); update collectSections/collectSection to populate bodyStart/bodyEnd. - tests/markdown-sectionizer.test.cjs: add 33 new behavioral tests for extractTaggedBlocks, replaceSection, and a DEFECT.GENERATIVE-FIX parity guard that asserts stripFencedCode and uat-predicate's _stripFencedBlocks agree on a shared 9-item corpus; documents the known 4-space-indent divergence. - docs/adr/1372-markdown-sectionizer-seam.md: list extractTaggedBlocks and replaceSection in §"The seam". - CONTEXT.md: update ### Markdown Sectionizer glossary entry with the two new exports. - docs/INVENTORY.md: add markdown-sectionizer.cjs row (alphabetically between loop-resolver and milestone). - docs/INVENTORY-MANIFEST.json: regenerated via gen-inventory-manifest --write. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(#1373): clear no-unsafe-assignment + unused-var lint in markdown-sectionizer Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(#1373): correct section offset/round-trip + CommonMark heading/fence edges; register eslint coverage FIX 1 (CRITICAL): Enforce content.slice(bodyStart,bodyEnd) === body invariant in both collectSection and collectSections. bodyEnd is now bodyStart + body.length instead of the raw stop-line offset, eliminating the trailing-newline overcounting that caused replaceSection to drop separator newlines (## A\nbody## B gluing bug). FIX 2 (MED): tokenizeHeadings now accepts ≤3-space indent (CommonMark §4.5) and empty ATX headings (## / ## ), text=''. 4-space indent correctly excluded. FIX 3 (MED): collectSection gains stopAtLevel option — stops at the next heading whose level ≤ stopAtLevel, independent of the opener's level. Enables state.cts ## sections that also stop at ### without abusing levelBounded. FIX 4 (MED): Backtick fence opener info string must not contain a backtick (CommonMark). Applied in both stripFencedCode and tokenizeHeadings fence state machines. Tilde fences unaffected. FIX 5 (LOW): "byte offset" → "character (string-index) offset" in HeadingToken / Section doc comments. FIX 6 (LOW): extractTaggedBlocks doc comment documents nested-tag non-support; test locks the non-greedy close-at-first-</tag> behavior. FIX 7: Add gsd-core/bin/lib/markdown-sectionizer.cjs to eslint.config.mjs ignores so tests/551-eslint-bin-lib-coverage.test.cjs passes (3/3). Tests: 107 pass / 0 fail (was 87; +20 new tests for FIX 1–4, 6). Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(#1373): gitignore tsc-built markdown-sectionizer.cjs (ADR-457 build-at-publish) The seam's compiled artifact must be a build-at-publish output like every other src/*.cts->bin/lib/*.cjs module (decisions, core, state, ...), not a committed file. Add it to the ADR-457 ignore list and untrack it; build:lib/CI regenerate it.
