# Project Patterns Reference

This skill contains detailed pattern documentation for this project.
See individual pattern files for full details with code examples.

Available patterns:
- [revalidated-execution-port.md](revalidated-execution-port.md) — Bind planned operations to adapter requests, revalidate them under lock, then apply through `ExecutionPort`.
- [root-confined-filesystem-port.md](root-confined-filesystem-port.md) — Access managed descendant files through a canonical root and no-follow relative-path operations.
- [target-local-resource-state.md](target-local-resource-state.md) — Mutate lifecycle evidence on exact harness bindings and preserve unselected sibling state.
- [identity-aware-rollback.md](identity-aware-rollback.md) — Roll back only proven owned identities and report post-observed residuals when restoration is incomplete.
- [validated-wire-contract.md](validated-wire-contract.md) — Serialize domain values through private wire DTOs and rebuild them through validating constructors.
- [validated-string-newtypes.md](validated-string-newtypes.md) — Represent bounded domain text with one validated, serde-aware newtype rather than raw `String`.
- [bounded-native-process-port.md](bounded-native-process-port.md) — Resolve binaries and run direct argument vectors through the bounded runner with explicit limits.
- [isolated-native-fixture-roots.md](isolated-native-fixture-roots.md) — Exercise native and filesystem behavior only inside test-support-owned temporary roots and fake binaries.
