What changed

RedSuite reads the outbox address announced by the validator's replayable receipt flow and finds its successful completion transaction. It ignores older transactions at the same address by requiring the completion to occur after the scheduling transaction. The announced-signature path remains available for older validators.

Recovery and rollback checks use the same receipt target. The authorization probe uses the current SentCommit instruction format.

Closes #301

Impact

The new lookup requires the validator to index transactions by outbox address after the account closes. It does not relax the receipt or authorization assertions.

Walkthrough

Receipt handling now supports legacy signature and outbox targets. Commit monitoring, restart recovery, and rollback checks use these targets to locate receipts or verify their absence.

Changes: Receipt discovery and recovery

Layer / File(s)	Summary
Receipt targets and lookup crates/redsuite-core/src/receipt.rs	The receipt module parses scheduling logs into signature or outbox targets. It retrieves matching receipts from transactions or outbox address history, and includes tests for both target formats and missing intent IDs.
Commit monitoring and recovery crates/redsuite-core/src/receipt.rs, redshift/src/scenarios/committor/commit_recovery.rs, redshift/src/scenarios/committor/settlement_lifecycle.rs	CommitWatch, confirmation-loss checks, restart recovery, and rollback checks use resolved receipt targets.
Scenario compatibility and diagnostics redhat/src/scenarios/chainlink/settlement_authorization/commits/buffers.rs, redshift/src/scenarios/committor/commit_snapshot_ordering.rs, crates/redsuite-core/src/signed.rs, Cargo.toml	The outbox scenario constructs ScheduledCommitSent with a SentCommit. Receipt inclusion and transaction error failures include additional context. The workspace updates its magic-api revision.

Receipt discovery supports the new outbox format, but unreadable transaction bodies can weaken rollback checks and missing metadata can abort lookup. These bounded issues warrant owner awareness and follow-up; broader validator compatibility failures remain unestablished.

Full details: Title check

Explanation

The title names the main change: settlement receipts are now discovered through outbox history. The raw summary confirms the receipt lookup now handles outbox targets alongside the legacy signature path. The title is specific and uses the conventional fix: prefix.

Full details: Description check

Explanation

The description states that RedSuite now reads the outbox address announced by the validator's receipt flow and finds the successful completion transaction. It also covers the retained signature path, the recovery and rollback checks that use the same receipt target, the SentCommit probe update, and the impact on validator indexing. This matches the changeset and the linked issue scope.

Full details: Linked Issues check

Explanation

Issue #301 requires parsing the outbox address and intent ID, finding a matching successful completion in outbox history after scheduling, retaining the legacy signature path, and using the same receipt target in recovery and rollback checks. receipt.rs implements these paths and validates intent and minimum slot. commit_recovery.rs and settlement_lifecycle.rs use the resolved target. Tests cover legacy and outbox target parsing and the required intent ID.

Full details: Out of Scope Changes check

Explanation

The magic-api revision update enables the validator receipt-flow integration. The SentCommit update supports the authorization scenario with the current instruction format. Signed error details and snapshot-ordering diagnostics improve failure reporting for the changed scenarios. These changes have a concrete connection to the linked issue or its validation, and no unrelated implementation is demonstrated.

Add unit tests for outbox completion parsing.

The new unit tests call only receipt_target_in_logs. No unit test calls parse_outbox_completion. The outbox completion parsing path has no unit coverage in this crate.

Add a test with a successful outbox-program transaction that includes a matching OUTBOX_INTENT_ID instruction. Assert that parse_outbox_completion returns the parsed receipt. Add cases for a transaction with meta.err set and for a transaction without an outbox-program instruction. Assert that each returns None.

425-425: Minor · Potential issue · Quick win

Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.

fetch_commit_receipt_by_intent now applies an outbox-program-instruction filter even when settled_receipt calls it to recover a legacy signature-target receipt. Legacy receipt transactions without that instruction would no longer be found.

The legacy restart-recovery scenario times out instead of confirming its settlement.

This can occur when: Restart recovery runs against an older validator whose receipt contains the matching intent ID but does not invoke topology::OUTBOX_INTENT_ID.

381-381: Minor · Potential issue · Heavy lift

Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.

The new outbox lookup depends on get_signatures_for_address retaining transactions indexed by the announced outbox address after that account closes; the PR context explicitly identifies this indexing as required, but the supplied code does not establish the validator counterpart.

Completed settlements cannot be found through the new target, and rollback checks may incorrectly observe absence.

This can occur when: A validator announces an outbox address but its transaction-history index omits that address after account closure.

381-381: Minor · Potential issue · Heavy lift

Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.

Outbox lookup examines only the latest 64 address signatures, with no pagination. A completion displaced beyond that window is never examined by the optional lookup or the polling lookup's initial history fetch.

A published receipt can be reported absent or its awaited lookup can time out.

This can occur when: More than 64 transactions involving an outbox address occur after the matching completion and before lookup begins.
