ah-xuc.8 reconcile: spec-driven claim, Triage bounce, parked buckets, per-run timeout Past Stand

Claim-path integration of Stage 2. Same-package constraint: this bead owns the internal/reconcile edits for the claim path; the finalize-path bead must not start until this one is committed.

iterate(): canonical buckets triage/blocked/question become parked buckets — superviseRuntime only (detached supervision persists runtime truth; no claim, no kill, no card moves, no comments). They are never claim sources and never terminal targets. Blocked and Question get real semantics in Stage 4; Stage 2 only reserves and parks them.

claim(): resolve the Task Spec via internal/spec from BoardTask.Labels plus Description. A validation failure bounces: MoveToBucket(triage) first, then one diagnostic comment listing the problems verbatim plus a hint to fix the spec and drag back to Ready, then event spec_rejected — move-then-comment discipline so a persistent move failure cannot spam comments; appendEvent dedup applies. No record is persisted and the card never goes to Failed for spec problems. Warnings (unknown fields) never block: append them to the claim comment.

Success path: the spec role name resolves through cfg.Roles; model override applies; the prompt renders over the frontmatter-stripped Body; resolved SkillPaths go into StartSpec.Skills; the effective timeout (spec override or config default) goes into StartSpec.Timeout and is persisted as Run.Timeout.

check(): deadline enforcement uses run.Timeout when positive, else cfg.Timeout — in both the running arm and the degraded neither-state arm.

Extend fakes_test.go (fake runner captures Skills and Timeout; board tasks carry Labels) and cover: each bounce class end to end, merge precedence reaching StartSpec, parked buckets neither claim nor kill while detached supervision still finalizes a finished runtime, per-run timeout enforced at the right boundary with the fake clock — both shorter and longer than the config default.

go test ./internal/reconcile/... green, go vet clean; bounce tests assert move-before-comment ordering and zero Failed transitions; parked-bucket tests assert no board writes; timeout tests cover run.Timeout smaller and larger than the config default

Additional: pre-existing gofmt drift in internal/reconcile/reconcile_test.go (comment alignment around lines 983-984 and 1345, present since before Stage 2) — run gofmt -w on the files you touch and fold the fix into this bead's commit.
