 Write exactly one parseable AquaSynth `.aqua` patch for each frozen $targetKind reference assigned to you. This is scene-audio parity, not IPA articulation. You may use ordinary voices, FM, AM/tremolo, filters, formants, noise layers, acoustic vocal/syrinx primitives, additive/PAD layers, curves, and helper voices.
 
 Generalization:
-- You own two target patches, but your report must compare both targets and state what reusable scene/instrument knowledge transfers between them.
-- The two patches may share instrument roles, texture roles, control idioms, and DSL conventions, but each patch should fit its own target's tempo/register/spectral evidence.
+- You own $SongsPerAgent target patches, and your report must compare all assigned targets and state what reusable scene/instrument knowledge transfers between them.
+- The patches may share instrument roles, texture roles, control idioms, and DSL conventions, but each patch should fit its own target's tempo/register/spectral evidence.
 - Future agents will receive distilled evidence from this trial when asked to zero-shot an audio production request. Make your `hypotheses.md` useful retrieval context: name what transferred, what did not, and what evidence would change your next patch.

   - `attempt evidence`: which attempt used it, score movement, candidate analysis facts, and what changed after listening to the rendered output;
   - `sugar sketch`: the shortest future syntax you wish existed;
   - `keep/cut verdict`: whether this abstraction should be mined into DSL sugar, kept as a stock patch idiom, or discarded.
-- Prefer abstractions that transfer across both assigned songs. A one-off trick is allowed only if you label it as target-specific and say why it should not become syntax.
+- Prefer abstractions that transfer across multiple assigned songs. A one-off trick is allowed only if you label it as target-specific and say why it should not become syntax.
 - Do not propose sugar that hides ownership. The future shorthand must still lower into visible syrinx, subtractive, additive/PAD, texture, pattern, scale, or curve owners.
