 | 2026-10-08 | `docs/readme-refresh` | sdk | no row changes | README was stale: it said the indexer is still being scaffolded, but it is built and running on testnet. Now documents the 16 public exports, the `bigint` and claim-link-fragment invariants, the list API routes, and the live indexer |
 | 2026-10-08 | `docs/m2-17-api-reference` | sdk | DONE: M2-17 | Added `packages/sdk/API.md`: every public export (client, preflight, receipts, links, hash, format, errors, types) documented with real signatures, params, return types, and a runnable usage example, read directly from the current `src/*.ts` source, not from memory. Linked from README. Verified: `pnpm lint`, `pnpm typecheck`, `pnpm test` (123/123 passed) all green. Closes issue #25 (seeded under `W-02`) |
 | 2026-10-08 | `docs/verified-payee-wording` | sdk | no row changes | Synced `AGENTS.md`/`docs/PRD.md`/`docs/ARCHITECTURE_ESSENTIALS.md` from `Kinlock-Org/.github` (`scripts/sync-docs.sh`): "a verified school or landlord" in the mission-statement-style sentences replaced with "a verified payee." Canonical source edited in `.github` PR #23 |
+| 2026-10-08 | `docs/link-doc-hub` | sdk | no row changes (org row W-10 tracked in `.github`) | Linked `Kinlock-Org.github.io` (the org's documentation-issue hub) from README, with `area:sdk` |
 | 2026-10-08 | `docs/docs-site-link` | sdk | no row changes (org row W-10 tracked in `.github`) | Linked the new hosted docs site (`kinlock-org.github.io`) from README |
 | 2026-10-08 | `docs/live-app-link` | sdk | no row changes | Linked the live testnet app (`kinlock-app.vercel.app`, `M3-22`) from README; also set as the repo's GitHub "Website" field |
 | 2026-10-07 | `docs/scf-readiness-fixes` | sdk | no row changes (org rows W-09/F-12 tracked in `.github`) | Part of an org-wide SCF open-source readiness audit (see `.github` `docs/scf-readiness.md`): filled the unfilled `Copyright [yyyy] [name of copyright owner]` placeholder in `LICENSE` and added `ISSUE_TEMPLATE/config.yml` (GitHub's community-profile check was reporting `issue_template: false` despite templates existing) |
