Phase C of the gloss feature. Lands the natural-language gloss
content that the resolver (Phase B2) and the runtime composer
(Phase B3) were prepared for. This is the user-visible payoff:
cold-start DEFINITION / RECALL prompts on pack-resident lemmas now
emit fluent grounded sentences instead of dotted-domain disclosure.
Authoring: five parallel subagents in ONE message block (a single
parallel dispatch, ~20s wall-clock vs ~95s sequential). Each
subagent received its pack's complete lemma + POS list and a strict
JSON-shape exemplar. Total returned: 326 raw gloss entries.
Assembly (this commit): the raw entries were partitioned by
lexicon-residency lookup (the resolve_gloss invariant enforced at
storage time), deduplicated within pack, sorted by lemma, written
to ``language_packs/data/<pack>/glosses.jsonl``, and each pack's
manifest received a new ``glosses_checksum`` field. 323 glosses
landed clean; 0 rejected.
Per-pack distribution:
en_core_cognition_v1 78 glosses
en_core_meta_v1 72 glosses
en_core_attitude_v1 40 glosses
en_core_temporal_v1 28 glosses
en_core_action_v1 26 glosses
en_core_quantitative_v1 24 glosses
en_core_spatial_v1 24 glosses
en_core_polarity_v1 16 glosses
en_core_causation_v1 15 glosses
Live-probe lift (fresh ChatRuntime per prompt):
BEFORE:
truth — pack-grounded (en_core_cognition_v1):
cognition.truth; logos.core; epistemic.ground.
No session evidence yet.
AFTER:
Truth is a claim or state grounded by evidence and coherent
judgment. pack-grounded (en_core_cognition_v1).
Same provenance. Same audit-trail content (the dotted domains are
still in lexicon.jsonl, the resolver can still read them, the
candidate object carries them verbatim). But the user-facing
surface is a sentence the user can actually read.
Eval-lane lift:
deterministic_fluency BEFORE AFTER
no_dotted_inventory_rate 0.3333 → 1.0000
no_provenance_only_rate 1.0000 → 1.0000 (held)
no_placeholder_rate 1.0000 → 1.0000 (held)
complete_punctuation_rate 1.0000 → 1.0000 (held)
finite_predicate_shape 1.0000 → 1.0000 (held)
surface_provenance_match 1.0000 → 1.0000 (held)
cold_start_grounding all metrics held at 1.0
warmed_session_consistency no_placeholder + telemetry_match held at 1.0
(warm_grounding_stability still 0 — separate fix)
cognition eval public 100 / 100 / 91.7 / 100 (BYTE-IDENTICAL)
cognition eval holdout 100 / 100 / 83.3 / 100 (BYTE-IDENTICAL)
The cognition eval bytes-identity holds because the eval checks
substring containment (case-insensitive after the format change).
Every lemma still appears in its fluent surface.
Hardening this commit enforces:
Lexicon-residency at storage time
tests/test_pack_glosses_content.py::test_every_gloss_lemma_is_lexicon_resident
walks every glosses.jsonl and asserts every lemma is present in
the same pack's lexicon.jsonl. Drift in glosses (an unratified
lemma sneaking in) fails the lane immediately.
Dual-checksum discipline
tests/test_pack_glosses_content.py::test_every_glossed_pack_has_matching_checksum
re-hashes glosses.jsonl bytes-on-disk and compares against the
manifest's glosses_checksum. Any tampering fails.
Immutable-lexicon invariant
tests/test_pack_glosses_content.py::test_lexicon_checksum_unchanged_by_gloss_landing
re-hashes lexicon.jsonl and compares against the manifest's
(original) checksum. Proves that adding glosses did NOT perturb
the lexicon seal.
High-freq lemma resolution
32 of the most-common conversational lemmas (truth, doubt,
fact, idea, self, true, important, now, place, make, effect,
always, ...) all resolve to a fluent surface end-to-end.
Test-suite drift this commit absorbed:
- tests/test_pack_grounding.py — three substring assertions
updated to be case-insensitive (gloss-backed surfaces capitalize
lemmas at sentence start, dotted-disclosure surfaces don't).
"No session evidence yet" assertion replaced with the
common-substring "pack-grounded" marker that BOTH forms emit.
- tests/test_pack_resolver_glosses.py — the back-compat test
pivots from en_core_cognition_v1 (now glossed) to en_minimal_v1
(deliberately unglossed). A new test pins the glossed case.
Files added:
language_packs/data/<pack>/glosses.jsonl (9 files, 323 entries)
tests/test_pack_glosses_content.py (9 contract tests)
Files modified:
language_packs/data/<pack>/manifest.json (9 files, glosses_checksum field)
chat/pack_grounding.py (lowercase "pack-grounded" tag)
tests/test_pack_grounding.py (3 substring assertions relaxed)
tests/test_pack_resolver_glosses.py (back-compat test pivoted)
Verification:
127/127 affected tests green.
9/9 new gloss-content tests green.
All three eval lanes report the lift documented above.
Cognition eval byte-identical.
