## [2.0.0-alpha.2] — 2026-06-01

### Added (Plan 2: API surface + UI shell)
- REST routes for the full entity tree:
  - `/api/spaces`, `/api/projects`, `/api/tasks` (with project + space scoping)
  - `/api/pages` + page revisions + `/api/pages/:id/backlinks`
  - `/api/refs` + `/api/refs/upsert`
  - `/api/resources` + dependencies + change history
  - `/api/resources/:id/source-docs` + `/api/source-docs/:id/resync` (gated by `ENABLE_RESYNC`)
  - `/api/agents` (owner-only) + agent token mint/revoke
  - `/api/conversations` + nested `/messages`
  - `/api/tags` + entity-scoped attach/detach via `/api/:entity_type/:entity_id/tags`
  - `/api/links` (POST/GET from|to/DELETE) for polymorphic entity links
  - `/api/pending-changes` + approve/reject with dispatch table covering
    page/project/task/ref/resource/source_doc × create/update/delete
  - `/api/audit/entity/:type/:id` + `/api/audit/actor`
  - `/api/search` unified FTS across pages, refs, source docs, messages
- Agent bearer auth middleware + capability tiering: owner allow, agent
  `write+scope` → allow, agent `suggest` → 202 + pending row, else 403.
- Approve and reject emit explicit `approve` / `reject` entries in the
  audit log with the original agent id preserved in the diff.
- Static SPA shell served from `public/`:
  - Three-column Cradle aesthetic (blackflame palette, Cinzel display
    headings, Cormorant Garamond body)
  - Hash-based router with views for home / space / project / page /
    reference / resource / search / inbox / sacred valley
  - `dom.js` safe builders — no `innerHTML` on API data anywhere; the
    explicit `html:` opt-in is used only by the markdown editor's
    preview pane, which sanitizes with DOMPurify
  - Sidebar Spaces tree with lazy project expansion, bottom Navigate
    section, pending-count badge shared with the topbar bell via a tiny
    `state.js` event bus
  - Topbar: brand, capture modal stub, global search (Enter →
    `#/search?q=`), pending bell, owner toggle
  - Page editor: split-pane markdown via marked + DOMPurify, save
    PATCHes `/api/pages/:id`, backlinks card
  - Reference detail: media block (image / YouTube embed / link),
    summary, metadata table, tag attach/detach, linked-from list
  - Resource detail: status header, dependencies + source docs +
    runbook pages columns, change history
  - Inbox: pending changes grouped by agent, approve → navigate to the
    resulting entity
- Test coverage: 185 tests across 43 files (113 new for Plan 2 routes +
  search + GET / shell smoke).

### Security follow-ups (deferred)
- Polymorphic IDOR risk on entity_links / entity_tags / attachments —
  acceptable today since the entire API is owner-token gated and there
  is one tenant; see `docs/security-followups.md` for the tighten-now
  vs defer decision.
- `pending_changes.action` CHECK constraint blocks `'upsert'` /
  `'add_dependency'` / `'remove_dependency'` actions emitted by some
  routes' `divertToPending` paths. Latent — only fires when an agent at
  suggest tier hits those specific endpoints. Mitigation options
  documented in `docs/security-followups.md`.
