WalkthroughBurnManager now routes orchestrator burns through readiness checks and a dedicated ChangesOrchestrator burn execution
Possibly related PRs
Suggested reviewers: Merge Risk: 🟠 High · up to This PR adds orchestrator burns that intentionally bypass receipt accounting, but current recovery and failure paths can reconstruct them as vault-direct, attempt receipt release or settlement without a reservation, or retry failures marked manual-only. That can strand redemptions and drift accounting after restart or failure, so the PR is not merge-ready until these paths are corrected or explicitly accepted by the owner. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

Learning: In this Rust repository, event-sourced aggregate apply_event methods must be pure, return (), deterministically replay historical events, and accept events without rejecting their ordering. Enforce valid event ordering in transition methods before events are persisted. Apply this contract consistently to aggregates such as Mint, ReceiptInventory, and BurnExcess.

Learning: In Rust mint and redemption aggregate modules, preserve message-shaped quantity conversion error variants when error enums derive Clone, PartialEq, Serialize, and Deserialize. Do not replace them with #[from] QuantityConversionError because QuantityConversionError::ParseFailed wraps rust_decimal::Error, which is not serde-serializable. Only adopt the shared error type if its serialization support and the codebase-wide error contract are redesigned accordingly.

Motivation
Redemptions in orchestrator mode need a distinct burn execution path. The orchestrator custodies receipts and walks them on-chain itself, so the bot-side receipt reserve/settle/release lifecycle must not run. Previously, the burn pipeline was built exclusively around the vault-direct flow, with no way to route orchestrator-mode redemptions differently.
Solution
A new
execute_orchestrator_burnmethod handles the orchestrator-specific path. Before submitting, it checksOrchestratorBurnReadinessvia the vault service:Ready— proceeds to submission.AllowanceInsufficient— records a classifiedBurnFailedevent and returns an error without submitting. This is treated as a deterministic, non-retryable failure requiring manual ops action (granting the orchestrator approval).VaultLogicMismatch— defers silently by returningOk(()), leaving the redemption inBurningso the next recovery pass re-checks health without consuming the retry budget.BurnExecutionPlangains anorchestratorconstructor alongside the renamedvault_directconstructor, and anis_orchestrator()predicate. All receipt lifecycle call sites (reserve_burn,settle_burn,release_reserved_burn) are guarded by!execution.is_orchestrator(). TheBurnParamsvariant is now stored directly on the plan and forwarded toIntendBurnandBurnTokenscommands, removing the repeated inline construction.On confirmation failure, non-
Unclassifiedclassifications skip the automatic recovery reservation entirely, sinceInsufficientReceiptsandAllowanceInsufficientrequire manual intervention and must not consume the retry budget.should_release_reserved_burnandextract_tx_hashare extended to handle the newVaultError::OrchestratorRevertedvariant, treating a decoded orchestrator revert as definitively consuming no receipts.Four integration tests cover the new paths: the happy path (verifying zero receipt-service calls and correct orchestrator params), the allowance gate (classified
BurnFailed, no submission), the health gate (silent deferral, redemption stays inBurning), and anInsufficientReceiptsrevert (classified failure with no recovery event emitted).Checks
