Description

## Purpose
Before Pi watchdog implementation proceeds, review `design-pi-stalled` and `implement-pi-stalled` for a complete, conflict-free WCC. Focus on false-positive safety, same-session proof, first-terminal-wins semantics, worktree/PID lease fencing, no cross-executor fallback, finite continuation budget, and real service-flow tests. Edit task descriptions/dependencies only; do not inspect or modify source.

## Validation
- [ ] Design and implementation boundaries are explicit and serialized with overlapping lifecycle/spawn work.
- [ ] Fixed five-minute meaningful-no-progress default is distinct from adaptive future policy.
- [ ] Fake-Pi and live human-flow scenarios cover slow-not-stalled, stalled, wait, long tool, restart, race, and explicit terminal outcomes.
- [ ] No continuation path can duplicate owner/process, mutate task status through messages, or silently change route.
- [ ] Quality findings and edits are logged before completion.

• 2026-07-26T11:40:04.082205507+00:00 Starting WCC quality review of design-pi-stalled and implement-pi-stalled; scope is graph descriptions/dependencies only, no source inspection or modification.
• 2026-07-26T11:42:40.671354074+00:00 QUALITY_FINDINGS: Existing WCC has the right intent but leaves safety-critical contracts implicit: Stalled is not distinguished from canonical task status; same-session proof is not a fail-closed tuple; worktree ownership vs per-process continuation lease is conflated; first-terminal race ordering is underspecified; ambiguous side-effecting tools can be replayed; numeric continuation caps are not required; and the live service flow does not enumerate all mandated slow/wait/tool/restart/race/terminal cases. Implementation is indirectly behind lifecycle/admission but not directly serialized with the long-lived supervisor daemon-loop work.
• 2026-07-26T11:42:40.771170173+00:00 FANOUT_DECISION: stay inline — this is a two-description/dependency WCC review; parallel subtasks would edit the same graph records and violate same-files/same-records serialization.
• 2026-07-26T11:44:59.578083803+00:00 EDITED_WCC: Strengthened design-pi-stalled and implement-pi-stalled descriptions with lifecycle-kernel authority, process-epoch vs worktree-attempt lease boundaries, fail-closed same-session/route proof, fixed 300s policy vs future adaptation, first-terminal race CAS, side-effect replay quarantine, finite epoch+elapsed budgets, message inertness, exact-route-only behavior, and exhaustive Fake-Pi/real-service test matrices.
• 2026-07-26T11:44:59.615213196+00:00 DEPENDENCY_EDITS: Added direct implement-pi-stalled -> implement-authoritative-lifecycle prerequisite (in addition to admission/design) and serialized shared daemon-loop work as impl-supervisor-hard-agent -> implement-pi-stalled. Existing implement-pi-stalled -> implement-lazy-evaluation ordering remains intact.
• 2026-07-26T11:46:01.630840747+00:00 CONFLICT_RESOLUTION: Added an explicit ratification seam for the lifecycle design’s generic RuntimeExit/NoCompletionProtocol -> AttemptFailed rule. Pi continuation may defer attempt terminalization only through a persisted policy-valid process-epoch continuation authorization handled by the lifecycle kernel; observer-side special casing and weakening generic executor behavior are forbidden.
• 2026-07-26T11:46:23.803693238+00:00 VALIDATED: WCC descriptions explicitly satisfy fixed 300s meaningful-no-progress vs future adaptation; Fake-Pi and installed-binary real-service flows enumerate slow/stall/wait/long-tool/restart/race/done/fail/manual outcomes; session/route proof, first-terminal-wins, PID/worktree fencing, side-effect quarantine, message inertness, finite budgets, and no fallback are all normative.
• 2026-07-26T11:46:23.847315231+00:00 VALIDATED: Dependency graph directly orders implement-pi-stalled after design, authoritative lifecycle, and admission; orders impl-supervisor-hard-agent after the Pi implementation; preserves lazy-evaluation downstream; wg analyze reports no cycles. No tracked source/doc files changed, so cargo/commit/artifact steps are not applicable to this graph-description-only review.
