The v1 gloss-quote detector used a 4-token contiguous window of
≥4-char tokens. That heuristic was too strict for the actual ADR-0084
brief gloss style, which is deliberately short and primitive-only:
light "visible medium that reveal truth" 5 tokens ≥4 chars
parent "person with a child" 3 tokens ≥4 chars ← can't window
recall "get memory from before" 3 tokens ≥4 chars ← can't window
wisdom "good use of knowledge" 2 tokens ≥4 chars ← can't window
Result: post-PR #65 baseline showed gloss_quote_rate=0.0% even though
the pack-grounded composer was visibly emitting glosses verbatim:
surface: "Parent is person with a child. pack-grounded (en_core_relations_v1)."
gloss: "person with a child"
window: could not even form
Replace with substring match against the gloss text. The composer
emits the gloss verbatim (no paraphrasing — that's the no-LLM
discipline), so substring is exact, high-confidence, and trivially
correct:
gloss_quoted ⟺ gloss.lower().strip() in surface.lower()
Re-baselined v1/public (26 cases):
gloss_quote_rate: 7.7% (false-positive 4-token window noise)
→ 0.0% (post-#65, broken metric)
→ 11.5% (this PR, real signal)
The other four metrics unchanged. 3/26 cases (DEFINITION on
``evidence``/``recall``/``parent``) are detected as gloss-quoted now,
which matches reality — the pack-grounded composer at
chat/pack_grounding.py:398 has been gloss-aware all along; it just
had no glosses to quote pre-#65.
Why this is just a heuristic refinement, not a contract change:
The contract.md still says v1 has NO pass thresholds beyond
versor_closure_rate==1.00. The lane's job is to establish baseline
distribution. The heuristic was *measuring the wrong thing* — fixing
the measurement is a contract clarification, not a contract change.
Tests added (TestGlossQuote, 4 cases):
- short brief-style gloss detected via substring
- chain-walk surface for same lemma NOT counted as gloss-quoted
- unknown term returns False
- empty terms returns False
Updated the function docstring with the post-#65 context so future
readers understand why v1's contract predicted 0% but reality is ~12%.
