# Capabilities and release limits

| Behavior | Current status |
|---|---|
| Ordinary scale motion, rests and held chord tones | Enumerable and validated |
| Complete scalar/third-stride groups | Reachable; exact scale indices, whole rhythm groups |
| Heard-theme return and inverted answer | Reachable from actual realization; no required count |
| Approaches, enclosures, prepared chromatic connections | Reachable joint actions; target, time and register validated |
| Anticipation with hold or deliberate reattack | Reachable and separately validated |
| Stable/resolving colors and anticipated colors | Reachable; complete sounding exposure checked |
| Delayed semitone resolution | Pending across actions; exact target and bounded deadline required |
| Prepared suspension and named blues inflection | Validators retained; no dedicated new action constructor yet |
| Optional full head quotation | No new constructor; source influence currently uses ordered interval relationships and rhythm evidence |
| Two-sided revision / phrase-level destination lookahead | Not implemented by the local action policy |
| All six strings, frets 1–12, no opens | Shared physical domain and whole-line fingering |
| Source-only independent accompaniment | Existing canonical sparse comping retained |
| Exact construction coverage for all four targets | Demonstrated by constrained derivation plus final harmonic validation; not a production winner |
| Exact unrestricted reproduction of all four targets | Requires the separate full-export gate; a fit/derivation alone is insufficient |

A complete route is indivisible, but many independent single attacks remain available. This flexibility removes former coverage restrictions without proving melodic coherence. Source relationships are richer than an unordered interval set but remain a limited identity model. Register and fingering are separate; TAB legality is not biomechanical certification.

Unsupported written chords still fail explicitly. No source harmony is manufactured from a target. Electric may continue over the returning vocal pickup under the latest authorized allocation; vocal timing is unchanged. No dynamics, velocity shaping or new playback feel was introduced.
