Wires observational telemetry on the composer-vs-graph atom-set
relationship. Phase 1 is strictly observational: no enforcement,
no surface mutation, no grounding-source change, no trace-hash impact.
New telemetry fields on TurnEvent + ChatResponse:
composer_graph_atom_status ∈ {equivalent, divergent,
graph_unconstrained,
composer_no_atoms,
not_applicable, ""}
composer_atom_set_hash SHA-256 over sorted unique atoms
graph_atom_set_hash SHA-256 over sorted unique atoms
composer_graph_atom_overlap_count int
Composer atoms come from existing pack candidate metadata
(pack_semantic_domains channel through _maybe_pack_grounded_surface).
Graph atoms come from build_graph_from_input + resolve_lemma on
node.subject/predicate/obj — no prose parsing. When a grounded
composer path lacks explicit atom provenance, status is
'composer_no_atoms'.
New pure helper:
chat/atom_equivalence.py — normalize_atoms, hash_atoms,
atoms_for_graph_nodes, compare_atom_sets
Tests (tests/test_composer_graph_atom_equivalence.py):
- Pack DEFINITION path produces observable equivalence
- Divergent atom sets produce distinct hashes
- Register invariance: atom hashes + status identical across
{neutral, terse, convivial}; trace_hash also constant (R5 axis)
- Anchor lens engaged case still ASCII-only on surface
- No prose-parsing helper symbols introduced in runtime.py
(extract_candidate_surface_lemmas, surface_lemma,
parse_surface_atoms) — enforces Phase 1 boundary
Performance note: build_graph_from_input now runs on every warm
English turn (previously only when forward_graph_constraint=True).
Phase 1 accepts this cost to make the telemetry universally
available; Phase 2+ can introduce a feature flag if needed.
