Names the structural gap discovered in the first end-to-end
CompositionClaim ratification (2026-05-27 post-#393):
ratification handler writes JSONL artifacts cleanly, but no runtime
code reads compositions/*.jsonl or frames/*.jsonl. Two of three
sub-types ship the ratification half of the loop without the
consumption half.
State:
lexicon/ writer ✓ reader ✓ (LexicalClaim — closed)
frames/ writer ✓ reader ✗ (FrameClaim — half-open)
compositions/ writer ✓ reader ✗ (CompositionClaim — half-open)
Proposes one bundled PR (CW-1 + CW-2) mirroring the proven
generate/comprehension/lexicon.py::load_lexicon pattern:
CW-1 — Frame consumption: pack-compile frames/*.jsonl into a
runtime-loadable artifact; new load_frame_registry()
loader; reader wire.
CW-2 — Composition consumption: pack-compile compositions/*.jsonl;
new load_composition_registry(); injector wire in
generate/recognizer_anchor_inject.py.
Hard requirements: SAFE_COMPOSITION_CATEGORIES allowlist enforced
at both write and load (defense in depth); polarity "falsifies"
honored; manifest checksum extended per CLAUDE.md "Semantic Pack
Discipline"; empty-registry runtime byte-identical to today.
Truth-test pinned: success is the EVAL DELTA, not the artifact
append. PR is "done" when case 0019 (the canary I ratified) admits
under train_sample, train_sample moves from 3 correct / 47 refused
to ≥4 correct / 46 refused, case 0050 stays refused, wrong==0 holds.
This brief is orthogonal to the workbench UI wave (W1..W4); both
can ship in parallel. Recommended operator: Opus (load-bearing
wrong=0 surface; same rigor as CC-2).
