⚙️ CodeRabbit configuration file
Focus on providing constructive criticism. Whenever you see a suboptimal approach, suggest more idiomatic or robust alternative(s). Flag potential footguns. Suggest FP alternatives to mutable/imperative code. Point out architectural flaws like leaky abstractions, tight coupling, wrong level of abstraction, poor type modeling, over-abstraction, unclear domain boundaries. Code should generally be organized based on business concerns rather than technical aspects - suggest improvements if you find violations. Point out gaps in test coverage but suggest tests that are not too coupled to the implementation and actually test domain invariants and business logic

⚙️ CodeRabbit configuration file
Focus on the contents of the docs and not on cosmetic things like markdown formatting. We use markdown files for various docs including but not limited to the north star system specification, SPEC.md, the plan for how to get there, ROADMAP.md, guidelines for AI contributors, AGENTS.md, project overview and instructions for human contributors, README.md. Think about the target audience of a document when deciding what comment to leave. For specifications and designs, suggest potential product, architectural, and UI/UX improvements. For plans, suggest changes that would make things more parallelizable and deliverable-focused. For instructions, suggest better rules and guidelines and point out missing instructions. In all cases, flag needless bloat, prefer clear concise writing, and consider the structure of the document and order of the sections

Learning: In Rust signer-intent tests, keep aggregate-specific raw event-seeding helpers local to the relevant aggregate test module when they hardcode an aggregate type, such as `Mint` or `Redemption`. Keep event-history setup adjacent to its aggregate tests, and avoid centralizing small, aggregate-specific helpers in `src/test_utils.rs` unless they provide clear shared behavior across multiple aggregates.

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 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>)`).

src/**/*.rs: Use the committed SQLx cache for offline builds and regenerate it against a disposable local database when stale.
Organize Rust code by business feature/domain rather than technical layers; avoid catch-all modules such as types.rs, error.rs, models.rs, utils.rs, helpers.rs, http.rs, dto.rs, entities.rs, and services.rs.
Commands must validate current aggregate state and produce events; apply(event) must deterministically update state, remain pure, and never fail.
Events are permanent: never remove or change committed events, and add only events required by the current feature.
Services must model coherent domain capabilities, decouple aggregates from external systems, support mocking, and avoid traits that merely wrap commands or persistence operations.
Use enum-based, query-oriented states for views; do not wrap view data in confusing nested Options when GenericQuery::load already returns Option.
Always read views with GenericQuery::load(); never use raw SQL to parse JSON from view tables. Cross-aggregate queries must use dedicated SQL read models, indexes, or GenericQuery iteration.
Use structured tracing fields such asinfo!(key = %value, "message"), not interpolated values in log messages.
Logs inside loops or per-item iterations must be DEBUG or TRACE; use summary logs before or after the loop at higher levels.
Never log API keys, private keys, credentials, or other secrets.
Error types must store typed values directly, not string representations produced with format! or to_string().

⚙️ CodeRabbit configuration file
Focus on providing constructive criticism. Whenever you see a suboptimal approach, suggest more idiomatic or robust alternative(s). Flag potential footguns. Suggest FP alternatives to mutable/imperative code. Point out architectural flaws like leaky abstractions, tight coupling, wrong level of abstraction, poor type modeling, over-abstraction, unclear domain boundaries. Code should generally be organized based on business concerns rather than technical aspects - suggest improvements if you find violations. Point out gaps in test coverage but suggest tests that are not too coupled to the implementation and actually test domain invariants and business logic

⚙️ CodeRabbit configuration file
Focus on the contents of the docs and not on cosmetic things like markdown formatting. We use markdown files for various docs including but not limited to the north star system specification, SPEC.md, the plan for how to get there, ROADMAP.md, guidelines for AI contributors, AGENTS.md, project overview and instructions for human contributors, README.md. Think about the target audience of a document when deciding what comment to leave. For specifications and designs, suggest potential product, architectural, and UI/UX improvements. For plans, suggest changes that would make things more parallelizable and deliverable-focused. For instructions, suggest better rules and guidelines and point out missing instructions. In all cases, flag needless bloat, prefer clear concise writing, and consider the structure of the document and order of the sections

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>)`).

Timestamp: 2026-08-03T04:18:14.690Z
Learning: In Rust signer-intent tests, keep aggregate-specific raw event-seeding helpers local to the relevant aggregate test module when they hardcode an aggregate type, such as `Mint` or `Redemption`. Keep event-history setup adjacent to its aggregate tests, and avoid centralizing small, aggregate-specific helpers in `src/test_utils.rs` unless they provide clear shared behavior across multiple aggregates.

Advances RAI-1138: with the
Heldstate in place (#236), the freeze must actually gate the flow at the one point that sees every redemption — the boundary between detection and the Alpaca redeem call, before either side has moved.Solution
RedeemCallManager::handle_redemption_detectedreads the asset's freeze status in-process from the tokenized-asset view (no HTTP) before calling Alpaca; frozen → dispatchHoldinsteadrecover_single_detected) now also acceptsHeldaggregates so a drain re-runs the same idempotent handlerChecks
