Strengthen JobProtocol model after independent review. Replace tautological invariants with non-trivial ones, allow multi-shot coordination loss and re-partition, fix reap/progress lifecycle, enable deadlock checking via Done, and add stress and multi-shot TLC configs.

SPECIFICATION SafetySpec
CHECK_DEADLOCK TRUE
\* Stress envelope: MaxProgress=2 (partial resume), MaxAttempts=2 (retry),
\* multi-service faults (Coordination+Durable), single-shot fault budgets.
\* Deeper multi-shot budgets live in Remora.cfg; deeper MaxAttempts in RemoraFencing.

Specify fenced activation and source credential contracts Define bounded reservation recovery, exact activation replay fencing, immutable source identities, and deployment-owned secret and target policy boundaries. Align the OpenAPI contract and add a split-store activation safety refinement.

Weaken live progress to a coordination-only hint (IF-6). Drop LiveProgressAligned in favor of well-formedness and lease-compatible progress, stop durable CAS from clearing Redis progress, and add ambient ClearStaleLiveProgress so TLC matches Postgres + Dragonfly separation.
