[EPIC C3] Composition studio and governed generative experiments #6

Outcome

Inspectable patches and selected authoring, spatial-legibility, writing or AI experiments that answer a demonstrated composition question.

Placement and activation

Master roadmap: #2. C3 is optional. A specific proposal may start from the accepted score and minimal contract; a general studio is required only when the proposal actually uses one.

Canonical numbering is C0–C6. Local source/review evidence is a prerequisite only for the selected path; whole optional epics are not universal release gates.

Child work

• #28 — Patch grammar and human/machine score distinction
• #29 — Deeper color, geometry/perceptual studies; C1 baseline already verified
• #30 — Layered poetry/reversible legibility; C1 space baseline already verified
• #31 — Local authoring studio if authoring needs justify it
• #32 — Grounded computation/AI with provenance and evaluation
• #33 — Replayable publication/audiovisual export
• #58 — New artist-authored writing as an explicit edition change

Evidence gates

New writing names a missing function in existing language. Computation/AI names a question not adequately tested by simpler deterministic rules. Imported text remains data; sources, model/configuration, transformations, failures and artist selections remain inspectable. Routes belong to C2 #24; sound/performance to C4 #34. Neither is a mandatory C3 dependency.

Completion evidence

Record deliverable, source/score/software versions, exact-head checks, deployment identity where relevant, limits and artist decisions. Planning completion never establishes runtime or artistic acceptance.
