pingqiuandClaude Opus 4.6 4df61f290b fix: true mid-executor invalidation test via OnStep hook
CatchUpExecutor.OnStep: optional callback fired between executor-managed
progress steps. Enables deterministic fault injection (epoch bump)
between steps without racing or manual sender calls.

E2_EpochBump_MidExecutorLoop:
- Executor runs 5 progress steps
- OnStep hook bumps epoch after step 1 (after 2 successful steps)
- Executor's own loop detects invalidation at step 2's check
- Resources released by executor's release path (not manual cancel)
- Log shows session_invalidated + exec_resources_released

This closes the remaining FC2 gap: invalidation is now detected
and cleaned up by the executor itself, not by external code.

pingqiuandClaude Opus 4.6 5b63d34d6b fix: snapshot+tail WAL pin failure cleanup + true mid-executor epoch test
Finding 1: PlanRebuild snapshot+tail WAL pin failure now fail-closed
- InvalidateSession("wal_pin_failed_during_rebuild", StateNeedsRebuild)
- Snapshot pin released, session invalidated, no dangling state
- New test: E2_RebuildWALPinFailure_SessionCleaned

Finding 2: True mid-executor invalidation test
- Executor makes 2 successful progress steps (60, 70)
- Epoch bumps BETWEEN steps (real mid-execution)
- Third progress step fails — session invalidated
- Resources released via executor cancel
- New test: E2_EpochBump_AfterExecutorProgress

pingqiuandClaude Opus 4.6 332f598606 fix: close P3 failure classes — session cleanup, causal logging, CancelPlan
Finding 1: PlanRebuild now invalidates session on pin failure
- FullBasePin failure → InvalidateSession("full_base_pin_failed", StateNeedsRebuild)
- SnapshotPin failure → InvalidateSession("snapshot_pin_failed", StateNeedsRebuild)
- No dangling rebuild session after resource acquisition failure

Finding 2: Rebuild source logging shows causal reason
- plan_rebuild_full_base now logs: untrusted_checkpoint,
  trusted_checkpoint_unreplayable_tail, or no_checkpoint

Finding 3: CancelPlan for address-change cleanup
- New RecoveryDriver.CancelPlan(plan, reason): releases resources +
  invalidates session + logs plan_cancelled with reason
- Changed-address test uses CancelPlan (not manual ReleasePlan)

Finding 4: Executor-level epoch-bump test
- Executor's mid-step invalidation detection catches stale session
- Resources released via executor release path, not manual cancel

pingqiuandClaude Opus 4.6 56afa55f13 feat: add P3 failure-class validation through planner/executor (Phase 06)
6 new tests (validation_test.go) mapped to tester expectations E1-E5:

E1/FC1: Changed-address restart through planner/executor
- Active session invalidated by address change
- Sender identity preserved, old plan resources released
- Log shows: endpoint_changed → new session → plan → execute

E2/FC2: Epoch bump mid-execution step
- Partial progress, epoch bumps between steps
- Further progress rejected, executor cancels with resource release
- Log shows: session_invalidated + exec_resources_released

E3/FC5: Cross-layer proof — trusted base + unreplayable tail
- Storage: checkpoint=50, tail=80 → unreplayable
- RebuildSourceDecision → FullBase (not SnapshotTail)
- FullBasePin acquired, executed through RebuildExecutor, released
- Log shows: plan_rebuild_full_base (observable reason)

E4/FC8: Rebuild fallback when trusted-base proof fails
- Untrusted checkpoint → full-base, full-base pin fails → error
- Untrusted checkpoint → full-base, full-base pin succeeds → InSync
- Log shows: full_base_pin_failed

E5: Observability — full recovery chain logged
- Verifies 7 required log events from assignment through completion

Delivery template:
Changed contracts: P3 validates planner/executor path, not convenience
Fail-closed: epoch bump mid-step releases resources + logs cause
Resources: cross-layer proof chain validated end-to-end
Carry-forward: FC3/FC4/FC6/FC7 sufficient from prior phases
