Plan: C API and Arithmetic Contract
Scope
Resolve the P2-02 half of issue005: validate the complete public schema
before extraction, make caller errors explicit, and eliminate signed
overflow for valid inputs.
Resolution Path
- Lock malformed single/batch vectors, bad penalty scalars, out-of-range integers, and a valid extreme-width calculation with direct C red tests.
- Validate vector types, n/n+1 lengths, scalar types, positivity, and signed 32-bit range before allocating or extracting.
- Register one
ekp-c-invalid-inputcondition for caller errors; retain nil only for allocation/no-result. - Widen DP line-metric, adjustment, flexibility, and rest intermediates to 64-bit without changing the 15-field ABI.
- Propagate module signals through the enabled Elisp dispatcher.
- Build release/sanitizer profiles and run focused/full ERT plus fuzz.
Non-goals
- No new algorithm or C tokenization.
- No change to valid 15-field layout or result shape.
- Build command/profile portability is the next atomic task.
Rollback
Restore permissive extraction, int32 intermediates, C 1.5 requirement, and the error-swallowing dispatcher. Valid persisted data is unaffected.
