Local calculation only. Nothing you paste is uploaded, stored, or sent to the ingest API.

Hashing is an optimization, not a gate

Missing context or a failed local calculation? Send the normal update. The API still validates, merges, hashes, and detects unchanged content. Never submit content_hash in the request.

This v2 creditor repair requires the operator's backfill. Refresh cached sync-state hashes after repair; API 4.2.0 availability must be checked in your target environment.
