What changed

settlement_lifecycle failed intermittently with completion for intent N is visible. The rejection fixtures read intent N from the logs of a transaction the ER rolled back. The intent counter lives in the MagicContext account, so the rollback reverts it too. The next intent scheduled by a concurrent fixture then gets the same ID and the same outbox PDA, and its legitimate completion trips the absence check. In the remote failure (validator 5b523263), the colliding intent 5 was test_failed_undelegation_lockout's patched undelegation.

The absence check now also requires the completion's payer to match the rejected fixture's payer. Each rejection fixture uses a freshly funded payer, so a completion from that payer can only come from the rejected intent.

Walkthrough

ensure_receipt_absent now accepts a payer. For outbox targets, a matching intent completion triggers rejection only if its payer differs from the supplied payer. The rejected-intent scenario passes the payer’s public key.

Changes: Payer-aware receipt absence check

Layer / File(s)	Summary
Add payer filtering to receipt absence checks core/src/receipt.rs, redshift/src/scenarios/committor/settlement_lifecycle.rs	ensure_receipt_absent accepts a payer and checks the payer of matching outbox completions. The rejected-intent scenario supplies the payer’s public key. The non-outbox absence check is unchanged.

Merge Risk: Low · up to 6ece5

The outbox payer filter implements the intended check. Signature targets still ignore the payer argument, leaving a bounded API-contract inconsistency; clarify or align that behavior. Otherwise, the change is mergeable with owner awareness.

Add coverage for the payer filter.

The rejection fixtures can pass without a completion for the intent. They can therefore miss an inverted payer comparison. Add tests with the same intent ID and matching, different, and missing payers. Assert that only the matching payer causes the absence check to fail.

for a Signature target causes an error only when its payer matches the payer
