Set CapabilitySelection on decisions that have Slots.HasFn=true, so
ResolveActionCandidate reads from the authoritative record. Backward
compatibility tests verify that decisions without CapabilitySelection
still resolve via Slots.HasFn.
Introduce ActionValidationStatus enum (valid, unresolved, missing_argument,
invalid_argument, ambiguous_target) as the typed classification of validation
outcomes. ActionValidationResult now carries Status instead of boolean flags.
Backward-compatible: Unresolved() and Valid() methods preserved on the result.
Existing validation behavior unchanged: only blank Fn produces invalid_argument.
All downstream behavior (proposeGap, confirmation, task_status, praxis, hexis)
unchanged.
Tests added for all five status values, backward compatibility, and the full
validation → execution boundary.
Introduce the typed boundary between routing and action resolution:
- ActionCandidate: Fn, Args, Source (route|matcher), Producer, Confidence
- ResolveActionCandidate(dec, m): standalone function usable by both
the daemon and the eval harness
- Update eval harness Reach() to use ResolveActionCandidate instead of
duplicating the matcher fallback logic
This is the routing-side half of the action-resolution boundary.
The daemon integration follows in the next commit.
