T-Y5VW-dashboard-stale-inflight-gates

Status: closed/superseded · Impact: medium · Complexity: small

Goal

Stage 6 of D-S30G-task-state-plane-split. The dashboard’s staleness signal must be correct on both sides of the cutover, and lease gates become visible on the task row — the dashboard is the run-state surface that replaces Obsidian in-flight visibility.

Today

Location	Role today
apps/sdlc/lib/services/dashboard/server.ts	stale_inflight = status_group in-progress ∧ no lease; joins lease onto TaskRow; lease-mirror sync with degrade.
apps/sdlc/lib/services/dashboard/contract.ts	LeaseRow / TaskRow shapes; no gates.

Proposed

stale_inflight := (in-progress ∧ no lease) ∨ (active lease ∧ expiry_state expired ∧ phase ∉ {awaiting-review, blocked}). The first arm naturally vacates as in-progress disappears. Lease gates are projected into the joined lease object and rendered on the task row.

Approach

1. Extend the join and the stale_inflight derivation in server.ts.
2. Add gates to the lease projection in contract.ts and the client render.
3. Extend the lease-mirror test with an expired-working lease and a gates-carrying payload.

Files to touch

Location	Kind	Change
apps/sdlc/lib/services/dashboard/server.ts	modify	Dual stale rule; gates in the join.
apps/sdlc/lib/services/dashboard/contract.ts	modify	Gates on the lease projection.

Acceptance criteria

• AC-1: An expired lease in phase working marks its task stale even when frontmatter reads open/ready.
• AC-2: A lease in awaiting-review with expires_at: null is never marked stale.
• AC-3: Gates timestamps render on the task row when present.

Out of scope

• Static-site projection of lease state — T-UKGW-site-projection-lease-join.

Dependencies

• T-5G81-lease-payload-gates — the gates shape it renders.

Discovery context

• Scaffolded from D-S30G-task-state-plane-split (migration stage 6 of 7).
