Build-order step 1: the critical path everything else sits on. - StateStore: SQLite in WAL mode with synchronous=FULL, so every state transition and intent-log write is committed and fsynced before returning; a power cut cannot tear state - Durable intent log: begin_intent records a unit of work before it starts; commit/abort resolve it; pending intents survive restart - schema_version stamped from the first commit, with a sequential migration hook; a newer state file than the code supports is refused rather than misread - reconcile_on_boot (A3 first cut): pending intents are checked against external truth by registered reconcilers (observable checks, never model self-assessment); verified effects are committed, verified no-ops aborted, anything unverifiable gates to AWAIT_INPUT — never blind-resume - Lives in nisse_dev per spec 0.1: the library is extracted after the dev agent works, not designed up front - Integration test kills a subprocess mid-work with os._exit and verifies state integrity and intent visibility on reopen Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
