# Active path audit
|
||
|
||
Starting revision: `0e68f53` (`Cleanup`). The earlier implementation report is preserved in [baseline_0e68f53.md](baseline_0e68f53.md); its test and timing results do not describe this change.
|
||
|
||
Before: `production.generate_role → composer.compose → construction.Builder.propose → rhythm.Rhythms.realize + routes.Routes.realize → scoring.evaluate → one-phrase lookahead → placement → validation → notation/export`.
|
||
|
||
After: `production.generate_role → composer.compose → construction.Builder → operators.Operators + selection.Selector → bounded action repair → whole-solo placement → validation → notation/export`.
|
||
|
||
| Finding | Verified starting behavior | Change / remaining limitation |
|
||
|---|---|---|
|
||
| Alternatives chosen by hashes before evaluation | `propose` hash-selected timing, destination, treatment, register and first pitch; 32 proposals per batch | Enumerate shared actions before contextual ranking. Stable content ordering breaks score ties. |
|
||
| Complete target cannot pass allocation | Autumn acoustic lead-in was outside export; electric tail clipped before returning vocal | Source pickup measure allocated before composition. Full electric tail allowed with authorized vocal overlap; vocal unchanged. |
|
||
| Scorer overwritten / density silently omitted | Not reproduced: only four named phrase terms remained | One rational action evaluator; no hidden density setting. |
|
||
| Every unit closes | Not reproduced: old constructor had open alternatives, but handoff forced a 2–3 beat hold | Individual actions need no chord-tone stop; handoff can be short or silent. |
|
||
| Answer unreachable | Not reproduced: old chooser requested answers | New answer transforms the actual heard group as a complete candidate. |
|
||
| Expressions are post-processing only | Not reproduced: old proposals planned them jointly | Keep joint treatments; carry pending exact-target obligations across actions. |
|
||
| Missing expressive coverage | Reproduced against actual enumerated operators | General delayed approaches, reattacked anticipations, anticipated colors and separated enclosures. |
|
||
| Color octaves disappear | Midpoint rounding skipped alternating F-sharp octaves | Enumerate explicit legal octaves. |
|
||
| Repeated catalog parsing | Parent parsed catalogs that independent workers parsed again | Parent parse removed; content-addressed immutable JSON catalogs shared by workers. |
|
||
|
||
`Operators.at` consumes source harmony, physical domain and versioned data. It records proposed, rejected-by-rule and valid counts. `Builder.candidates` retains 24 representatives by kind/duration; pending obligations filter candidates before this cutoff. `Builder.compose` ranks complete actions and allows 16 deterministic backtracks. There is no wall-clock winner, reference-reader import or old-constructor fallback.
|
||
|
||
This is a local policy, not a globally optimized complete-phrase model. An all-onset frontier experiment was abandoned because of excessive work. Phrase objects group selected actions for validation/reporting; that grouping does not mean whole-phrase alternatives competed. This limitation matters to exact selection.
|
||
|
||
The development-only `audition.fit_selection` constrains the same enumerator to an explicit target to diagnose representability. Its fitter rolls in with ordinary ranking and updates shared coefficients at the first mismatch. A valid derivation is not proof that production selects it. The release comparison checks the exported unrestricted winner separately.
