Motivation

Burn verification was mode-agnostic: verify_burn_in_receipt and VaultService::verify_burn_tx always looked for a Transfer(owner -> 0x0) event, which is the vault-direct proof shape. Orchestrator burns have a structurally different two-leg shape — Transfer(owner -> orchestrator) (the transferFrom pull) followed by Transfer(orchestrator -> 0x0) (the burn) — so verifying them against the vault-direct shape always fails. Additionally, alternate-burn recovery in BurnManager::force_complete_burn was comparing orchestrator redemptions against a per-receipt plan that doesn't exist for orchestrator mode, and was unconditionally calling settle_reserved_burn even though orchestrator redemptions never reserve receipts.

Solution

Introduces BurnProofKind (in vault/orchestrator.rs) with two variants — VaultDirect and Orchestrator { address } — and threads it through verify_burn_in_receipt, VaultService::verify_burn_tx, and BurnManager::force_complete_burn.

verify_burn_in_receipt now dispatches on BurnProofKind: vault-direct verification is unchanged; orchestrator verification accumulates the pull leg (Transfer(owner -> orchestrator)) and the burn leg (Transfer(orchestrator -> 0x0)) separately and rejects the proof unless the pull total equals the burn total and neither is zero. A vault-direct-shaped transaction is rejected under an orchestrator proof, and vice versa.

force_complete_burn now branches on metadata.burn_mode when an alternate proving hash is supplied. Vault-direct alternate proofs are still validated against the per-receipt plan. Orchestrator alternate proofs are validated by checking that the verified nonce matches the persisted transaction's nonce, the verified shares equal the redemption's alpaca_quantity converted to 18-decimal share-wei, and no owner share transfers are present (orchestrator mode returns no dust on-chain). settle_reserved_burn is skipped entirely for orchestrator redemptions.

BurnProofKind is always derived from the redemption's own persisted burn_mode via From<VaultMode>, never re-resolved from the asset's current vault mode, so the proof kind stays authoritative through the incremental per-asset cutover period.

The mock records the last BurnProofKind passed to verify_burn_tx for assertion in tests.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Walkthrough

Changes

Force-complete burn verification now uses persisted burn mode and nonce data. Vault receipt verification distinguishes direct and orchestrator proof shapes. Orchestrator completion validates amounts and transfers, skips receipt settlement, and adds focused tests.

Mode-aware burn completion

Layer / File(s) Summary
Burn proof kind contract
src/vault/orchestrator.rs, src/vault/mod.rs
BurnProofKind maps vault modes to direct or orchestrator proof shapes. Vault verification APIs accept the expected proof kind.
Proof-aware receipt verification

Receipt parsing identifies the correct burner, tracks orchestrator pulls, validates burn amounts, and rejects invalid proof shapes.
Service and test-mock propagation
src/vault/service.rs, src/vault/mock.rs
Production and mock services forward proof kinds. Mock state and tests record, reset, and verify the selected kind.
Mode-aware force completion

Timestamp: 2026-02-12T03:36:52.079Z
Learning: In Rust recovery loops or similar retry patterns,INFO/WARN log statements that are immediately followed by return; or break; inside the loop body are acceptable because the loop runs at most once for the exit path and won't flood logs. The existing guideline about DEBUG/TRACE logs per iteration applies to repeated logging inside loops; use INFO or WARN for exit paths and avoid per-iteration DEBUG/TRACE logs in retry loops. When reviewing code, flag cases where a log level dominates per-iteration noise and suggest moving exit-logs outside the hot loop or gating by a condition, ensuring the log appears at non-repetitive times.

Learning: In Rust code, within loops that spawn long-running background tasks (e.g., tokio::spawn) such as detectors, monitors, or services, INFO logs inside the loop body are acceptable if the loop is bounded and each iteration launches a persistent background worker. This acknowledges a significant operational event per iteration without causing excessive log noise. Apply this guidance when the loop has a clear exit condition and the spawned task persists beyond the iteration. If the loop is unbounded or spawns short-lived tasks, prefer lower log levels or structured tracing to avoid log flooding.

Learning: In Rust error enums, follow the AGENTS.md constraint that variant names “must be generic when using #[from]” only for enum variants annotated with #[from] (i.e., variants that derive the `From` conversion for the wrapped error type). For variants populated via manual error construction/handling (e.g., created in code paths using `.map_err(...)`), the naming constraint does not apply—use descriptive or categorical variant names to group related failure reasons (e.g., `HttpClient(Box<dyn Error + Send + Sync>)`).

Learning: In Rust, when implementing the `std::fmt::Display`/`std::Debug` traits (or the core `std::fmt::Formatter`-using `fmt` method), the conventional single-letter parameter name `f` for `fn fmt(&self, f: &mut std::fmt::Formatter<'_>) -> std::fmt::Result` should be allowed. Do not flag `f` as a violation of a “no single-letter variable names” guideline; this name is an established Rust idiom for `Formatter`.
