/reconcile confronts declarative sources (TODO checkboxes, registry
statuses, ## Index) against real git/fs state and surfaces the gaps,
in 4 categories + contradiction candidates.
- lib/reconcile.sh: engine — body-only enumeration (never the Index),
git/fs oracles, BLK last-block-wins status, lexical deferral sweep,
contradiction candidates, pure reconcile_verdict kernel.
- lib/tests/run-reconcile.sh + fixtures (neutral-named): 20/20;
recursive-coherence T1 reds if the engine reads the Index (teeth).
- skills/reconcile/SKILL.md: thin orchestration + A/B/C write-back gate,
honest limits (lexical deferrals, contradictions surfaced not asserted).
- CLAUDE.md: Skill routing line.
Founding principle: never trust a declarative source as an oracle — the
skill practices what it preaches (tested). Built via writing-skills TDD.
