fix: mesh tier only for explicit reason:organic; never mesh compound/codegen failures

Assembly · Phase J4: bench compound-shape case + docs

Assembly · Phase J3: composition prompt + pipeline integration

Assembly · Phase J2: expose asm in the kernel sandbox

Assembly · Phase J1: anchor-mating core (geometry/assembly.py)

feat: route organic guided responses to the mesh tier (reason-tagged)

Reactive mesh · Phase M4: route-distribution bench + docs

Reactive mesh · Phase M3: mesh Modal endpoint + app wiring (flag-gated)

Reactive mesh · Phase M2: reactive mesh tier in pipeline

Reactive mesh · Phase M1: mesh adapter

fix: drop degenerate faces at final scale (Saturn / fine-tessellation shapes)

fix: generate non-regular shapes (pyramids, dipyramids, cones, etc.)

perf: fast-path fallback for shapes with an exact primitive (no wasted retry)

fix: guided_response suggestions must be {label,prompt} objects, not strings

Option A: route live codegen path through pipeline (gate + retry + fallback)

Option A · Phase A6: A/B harness + docs (final phase)

Option A · Phase A5: pipeline retry/fallback orchestration

Option A · Phase A4: codegen system prompt + Modal/app integration (flag-gated)

Option A · Phase A3: assembler + build-spec fixtures (bridge proof)

Option A · Phase A2: sandbox kernel + geometry repair

Option A · Phase A1: metric harness + golden set

fix: triangle-only geometry + explodeable multi-component shapes

feat: hybrid parameterization — instant dimensional transforms + regen-on-release

Phase 6: polish + submission — README, model card, backend tests

Phase 1: model output contract — test fixtures + schema/guardrail tests
