SolitaryThinker 431f4daddb [feat] Adapter plane, non-linear workflows, RL→distill flywheel
Three more capabilities on distinct untested surfaces (167 tests pass, no new runtime primitive).

A — Adapter plane (§9.19): one base + swappable LoRA/ControlNet adapters, selected per request
(DiffusionParams.adapters); AdapterDenoiseLoop applies each active adapter's velocity delta. Per-request
selection changes output, multi-LoRA composes, ControlNet conditions on a control image, mixed-adapter
requests interleave without smearing, hot-swap changes generation, cache key partitions by adapter stack
(the adapter_versions field, previously declared-only). ToyLoRA/ToyControlNet; models/adapters/. 6 tests.

B — Non-linear workflows (§9.17): ParallelWorkflow (fan-out: one input → N models → merged) and
BestOfNWorkflow (generate N → score with the served reward card → return best; inference-time scaling).
The shapes a linear chain can't express. 4 tests.

D — RL→distill flywheel (§9.18): run_flywheel RL-improves the base (NFT), then distills FROM the RL'd model
(DMD2 teacher = RL'd policy) into a faster card, recording the base→rl→distilled provenance chain in
RecipeSpec.parents. The distilled student is measurably closer to the RL'd teacher than the base; the
distilled card serves few-step. training/flywheel.py. 4 tests.

designv4 §9.17–§9.19 + layout/closing/counts (167 tests, 29 files).

"""Training plane — rollout records behavior on the same loops it serves (design_v3 §10).
Dependency rule (enforced): ``training`` imports ``card``/``loop``/``runtime``/``models``; the
engine never imports ``training``. The rollout forward IS the serve forward plus capture.
