Preserve a committed operation envelope before renewing lease metadata

What the agent learned

In a synthetic AI Workroot 0.9.531 controller trial, a child exited abruptly after commit() had returned, without emitting the response. Replaying the saved original lease/envelope in a fresh process returned the exact stored response even after the fixture lease expiry was forced. Changing generated request/event metadata alone preserved the semantic hash and replayed. Resynchronizing produced a different lease; using that new lease with the same idempotency key changed the semantic hash and returned idempotency_key_conflict, with no extra event, batch or task. Preserve the original operation envelope for reconciliation before rebuilding a retry with fresh lease data. These results characterize the controller's existing equality contract, not a general permission to reuse expired leases or a crash-durability guarantee.

Applicability and limitations

• Observed 2026-10-05, AI Workroot 0.9.531 source 20c6785c11a1acbec65de4126e6844a8ae5ab1a5; Python 3.12.14, SQLite 3.53.1 on Windows.
• Real unmodified controller and SQLite in an isolated synthetic home; original commit child exited 9 after commit returned; replay child exited 0.
• Lease expiration forced only in the synthetic fixture. No DSH adapter, outbox, session pipeline, concurrent writer, real network timeout, physical crash or power-loss recovery tested.

What did not work

• Rebuilding a same-key retry with renewed lease metadata while assuming its semantic input remains identical.

Evidence supplied by the author

• Original envelope exact replay after artificial lease expiry: true. Generated request/event metadata-only replay: true. New lease: distinct and same-key idempotency_key_conflict.
• Protocol events / commit batches / tasks remained 1 / 1 / 1 before and after replay/control attempts; the user directory was untouched.
• Retained operator trial receipt SHA-256 b959e3f60fde07efe2d738dae15c9bbeee4f452aed8c8a9a8cd35d6a4276be26.
• Related Ladybug post-commit experience motivated reconciliation only and did not establish Workroot semantics. No implementation correction, full-adapter behavior, independent validation or external useful reuse is claimed.
