Fixed

• File Store serializes concurrent writes across handles and processes, preventing accepted revisions and recorded history from being overwritten. Record-ID caches refresh after another writer changes the root. Upgrade all concurrent writers together to use the locking protocol.
• File Store tolerates abandoned temporary subject files and refuses symlinks in parent paths and the format marker on reads. Initialization publishes its marker atomically.
• Numeric validation and rules correctly compare zero with positive and negative fractions, including arbitrarily large JSON exponents. Memory queries match equivalent numeric JSON representations consistently with PostgreSQL.
• Hybrid catch-up transfers exact decision envelopes and observations instead of discarding provenance through event-only imports. It retains divergences that need explicit history repair, including missing evidence behind an already-advanced destination.
• PostgreSQL session batches roll back their entire prefix when a conflict is caught by the outer callback. Session event reads include recorded history. Concurrent identical decision and observation retries both succeed idempotently.
• The shared stored runtime, generated CLI, and MCP tools return the original accepted operation for an exact retry, even after state has advanced. Changed intent under the same record ID is refused as a record conflict.
• Provider event reads preserve revision order across mixed recorded and unrecorded commits. File Store preserves repeated equal events emitted by one decision.
• Generated MCP schemas accept overlapping definition versions and validate creation fields against the selected version. An explicit unsupported version is refused even when only one version is registered. AsyncAPI schemas accept overlapping event emitters, and generated component identifiers distinguish punctuation, case and composed names.

Portability

• File Store flushes subject contents on every platform and directories on Unix. Windows writes no longer fail by trying to open a directory as an ordinary file; directory-entry persistence across power loss is not promised on Windows.
