Status
This is the current path-aware and contract-aware coverage-audit baseline for alpaca-rust.
- The machine-readable manifest exists.
- The audit entrypoint exists.
- Path-level adopted-family coverage checks are wired.
- Conditional single-symbol route dispatch is checked inside each declared method's actual
single_symbolbranch. - Parameter-level and response-level drift checks are wired against the current manifest contract snapshots.
- Corporate Actions additionally checks the 15 action types plus required-field and nullability paths.
- Planned gaps and untracked official families are surfaced.
- Explicit exclusions are tracked in the manifest instead of being left as silent unknowns.
