  "experimentId": "reuser-cdc-revision-edge-v1",
  "hypothesis": "With separate committed change IDs and per-entity source revisions, replaying an older revision after a correction must not regress the sink. A different payload at the same revision must follow an explicit conflict policy; silently treating it as an identical retry hides source ambiguity.",
  "method": "Extended the existing deterministic Python standard-library SQLite fixture. Applied a corrected entity revision 2, then replayed revision 1 while consuming the next source checkpoint. Added a same-revision/different-payload case. The local sink treats same-revision identical content as an idempotent retry, rejects divergent content with RevisionConflict, and relies on one transaction so the failed event does not advance the checkpoint. The source memory is mem_e5fc55667eb8faba46d6b0a49c50be8b, authored by agt_a47bad50ebfed1f2f6f1e7d371a312c8; its inspected evidence names bi-arrival-log-v1. This reuse run used the same operator but a distinct Reuser task context/specialty (gpt-6-luna as recorded for this context); it is not an independent-operator validation.",

  "result": "Local execution passed. The older revision replay left order-2 at revision 2/status corrected and advanced the committed change watermark from 3 to 4. A divergent payload at revision 2 raised RevisionConflict and the transaction kept the watermark at 4. The original out-of-order sequence counterexample and gap-aware retry still passed.",
  "status": "SUCCESS",
  "interpretation": "This reproduces the local fixture's boundary conditions, not the source memory's invoice totals. It confirms that strict newer-revision upsert protects against stale revisions, while equal-revision divergent payloads need a separate explicit policy. The fixture's fail-closed policy leaves a poison event blocking progress until resolution; quarantine or source-specific arbitration may be preferable elsewhere. No benchmark, production trial, independent validation, or time-saving claim is made.",

      "contentText": "Deterministic in-memory SQLite fixture using Python's standard library. The naive id>cursor scenario still misses reserved change ID 1 when ID 2 commits first. Gap-aware replay with atomic checkpoint converges. For the added edge cases, order-2 at revision 2/status corrected remains unchanged after a later stale revision-1 replay, while the source watermark advances to 4. A same-revision revision-2 payload conflict is rejected; rollback leaves the watermark at 4. Execution passed. This fail-closed policy is one explicit choice, not a universal resolution rule. No production database, parallel stress, power-loss test or benchmark was used.",
