 - **Repo-wide docs link/index hygiene sweep: four broken relative links, three missing ADR cross-reference pointers, and four stale reference-doc index tables.** Superseded ADR-0021 has no in-body amendment pointer forward to the new Node floor decision. ADR-0069's Related line 404s to a renamed file — it links `0047-cli-render-seam-and-framework-free-cores.md` but the real file is `docs/decisions/0047-cli-framework-commander-ink-clack.md`. ADR-0071's `### K7.` header gives no in-header signal that it belongs to a separate numbering track. An independent repo-wide crawl of every relative markdown link under `docs/` found four genuinely broken links — one of which duplicates the ADR-0069→ADR-0047 link above — plus a wrong-subdirectory link in ADR-0062. Separately, `docs/reference/README.md`'s shared-core table lists only 5 of 11 real files; `docs/standards/documentation-style.md` §6's canonical-artifact registry is missing 6 of 11, including the safety-critical `llm-provider-seam.md`; `docs/reference/shared-core/agent-runner.md` is orphaned from both indexes despite being cited by six other docs; the `docs/reference/cli/` index is missing `accessibility.md` and `regression-harness.md`. Regenerate all four index tables from the real file tree, fix the four broken links, and add the three missing ADR pointers in one coordinated sweep; recommend a CI link-checker afterward to prevent recurrence. *(M · docs/decisions/, docs/reference/README.md, docs/standards/documentation-style.md, docs/reference/cli/ · #123, #124, #126, #143, #151, #251, #252, #253)*
 - **Trim two ADRs and one project-structure.md row that restate content already living verbatim in their own cited canonical doc.** ADR-0031 states "canonical types live in `llm-provider-seam.md`" and then spends roughly 250 lines re-deriving the exact same content that file already carries. ADR-0027's addendum states exact sandbox resource-cap numbers that already live in `expression-sandbox-spec.md`, even after the ADR's own preamble names that spec the single canonical home. `docs/project-structure.md`'s Apps table restates a hand-picked, now-stale CLI subcommand list instead of linking to `docs/reference/cli/commands.md`, which already owns it canonically, and has drifted out of sync as a direct result. All three are the identical CLAUDE.md rule-8 violation — trim each ADR to drivers/tradeoffs plus a citation, and replace the stale restated list with a link. *(M · docs/decisions/0031-*.md, docs/decisions/0027-*.md, docs/project-structure.md · #120, #121, #257)*

The Playwright e2e row is the one un-flagged not-yet-applicable row in an otherwise carefully phase-annotated doc. Add the two missing dependency rows, the tradeoff note, and the same Phase-3 flag every other not-yet-applicable row already carries, in one pass. *(S · docs/tech-stack.md · #246, #247, #140)*

The same clause also undercounts scope: `docs/roadmap/phases/phase-2.6-conversational-authoring.md` states the real target three times as `en, es, tr, fr, de`, and `README.md` repeats the same en/tr undercount. One rewrite of the shared clause in both `CLAUDE.md` and `README.md`, stating the correct five-language target with an explicit not-started qualifier, fixes all three. *(S · CLAUDE.md, README.md · #74, #260, #134)*

The language count is now settled by maintainer ruling (2026-07-26): the catalog is architected for n locales but **`en` + `tr` are what ship in Phase 2.6**, with `es`/`fr`/`de` staged — so the existing en/tr wording is correct on scope and wrong only on stage. One rewrite of the shared clause in both `CLAUDE.md` and `README.md`, adding an explicit not-started qualifier and naming the staged locales, fixes all three. *(S · CLAUDE.md, README.md · #74, #260, #134)*
 - **Add the six load-bearing terms missing from the glossary and refresh its stale "Last updated" header.** `docs/glossary.md` omits `ExecutionHost`, `ToolHost`, `ActionGuard`, `MediaStore`, `WorkflowEngine`, and `BudgetGovernor` — terms that recur across the ADR corpus without a defined home — and its "Last updated" header is over a month stale relative to the file's own content. Bundle both fixes into the same edit. *(S · docs/glossary.md · #135, #137)*
 - **Swap `docs/architecture/README.md`'s recommended reading order to match both target docs' own stated shipping order.** The recommended order puts `cloud-phase-2.md` before `managed-inference.md`, contradicting both documents' own stated shipping/dependency order (managed inference is Phase 5, cloud execution is Phase 6). Swap the two entries. *(S · docs/architecture/README.md · #157)*
