Add GET /api/v5/current/spaces/{id} — a packaged, computed-on-demand
snapshot of where a space is right now: current direction, counts,
attention signals (open questions, divergence, active work), active
work claims, open tasks grouped by intent, recent milestones, and
recent activity. Shared payload contract with the smriti current CLI
surface built in parallel.
Render it as the ProjectCurrentState panel at the top of LineagePage,
replacing the hand-rolled current-state summary. Extract a shared
_get_active_claims helper so the state and current endpoints report
active work identically. No schema changes.
Adds WorkTree schema and migration, /api/v5/worktrees CRUD, CLI and MCP worktree surfaces, targeted regression tests, health capability, and minimal docs. Live Postgres migration/manual localhost verification intentionally remain pending until the full backend provider-config gate is resolved.
The health endpoint now returns git_sha and a capabilities list so
agents can detect when the running backend is missing features they
need (e.g., claims, structured_tasks). Skill pack v1.8 teaches the
capabilities probe: check /health when a 404 or missing section
suggests the backend is stale, tell the human to restart.
Diagnosed from the autonomy validation where Codex hit a backend
without /api/v5/claims — the backend process was running old code.
