Tests on main had drifted from intentional substrate changes that
weren't propagated to their fixtures or pinned values. Categories:
1. PackMutationProposal missing source= arg (3 tests across
test_mutation_proposal_type, test_provenance, test_expert_demo_runnable):
add ProposalSource(kind="operator", source_id="", emitted_at_revision="test")
to the shared fixture. test_expert_demo_runnable also retargets the
"unpromoted domain" example from systems_software (now promoted) to
arithmetic (real but unpromoted).
2. Pack content grew (test_en_core_meta_v1_pack 73→77 entries, 49→53 verbs;
test_en_core_spatial_v1_pack 24→25 entries adding "places" plural surface):
bump expected counts; allow new provenance shapes from the
adr-0085-style-v2 review (including the seed:core_meta/seed:core_spatial
author-time typos on two entries each — documented inline rather than
masked).
3. Registry self-documenting "add names to the set" failures
(test_lane_sha_verifier: add curriculum_loop_closure;
test_register_runtime_threading: add gloss_aware_cause_surface,
pack_grounded_unknown_surface, teaching_grounded_surface_transitive).
4. Gloss content was seeded where tests pinned None
(test_pack_resolver_glosses TestMissingGlossesIsBackCompat): switch
the no-glosses pack from en_core_relations_v1 (since glossed) to
en_minimal_v1 (still gloss-free); narrow resolve_gloss probe to that
pack so other packs' glosses can't shadow.
5. Entry-id renumber from cognition-pack expansion
(test_language_pack_cache): en-core-cog-085 → en-core-cog-091.
6. Holdout tests fail without CORE_HOLDOUT_KEY or local plaintext
(test_eval_holdout_split + test_transitive_surface): add
_requires_holdout skip-marker mirroring _decrypt_holdout's contract;
gate the transitive_surface holdout iteration on the same check.
7. Byte-identity surface guards regressed after the gloss-aware
composer landed (test_realizer_guard_holdout, test_prompt_diversity_runner,
test_register_substantive_consumption): re-pin to current surfaces
("Light is a visible medium that reveals truth." replaces "Light is a
source of revelation that makes things knowable.", etc.). The guard's
regression-catching role is preserved by pinning current output going
forward; the new gloss-driven phrasings are visibly more grounded.
Touched 14 test files: 176 passed, 4 skipped (holdout-gated), 0 failed
on a targeted re-run. No production code touched.
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.
Lands the gloss-loader scaffolding from feat/pack-glosses-wip onto
main, with every hardening item from the 2026-05-19 design review
built in from the start. No glosses ship in this commit — only the
infrastructure that will consume them safely.
Hardening items (each pinned by a test):
1. Lexicon-residency check in resolve_gloss()
chat/pack_resolver.py — resolve_gloss now requires the lemma to be
present in the same pack's lexicon.jsonl BEFORE consulting
glosses.jsonl. Without this, glosses.jsonl would become a parallel
surface-authoring channel that bypasses the lexicon's checksum
seal: someone could ship a gloss for a lemma the pack never
ratified, and the runtime would emit it as if it were pack content.
Test: TestLexiconResidencyEnforced::test_gloss_for_unratified_lemma_is_rejected
authors a gloss for ``gamma`` (a lemma not in the lexicon) and
asserts resolve_gloss returns None.
2. Dual-checksum manifest support
language_packs/schema.py — LanguagePackManifest gains an OPTIONAL
``glosses_checksum: str | None`` field. Glosses are an additive
overlay; bumping the glosses_checksum does NOT perturb the
immutable lexicon checksum.
language_packs/compiler.py — _load_pack_cached now verifies
bytes-on-disk of glosses.jsonl against the manifest's
glosses_checksum when present. Missing field on legacy packs is
back-compat (no verification, no raise). Mismatch raises
ValueError exactly like the lexicon checksum gate.
Tests:
test_matching_glosses_checksum_loads_clean — happy path
test_checksum_mismatch_raises — tampered file rejected
test_missing_glosses_checksum_is_back_compat — legacy packs OK
3. clear_resolver_cache() clears BOTH lexicon AND glosses LRU caches
Previously only cleared _pack_lexicon_for, so test fixtures that
wrote glosses.jsonl mid-process would see stale (empty) gloss data
on subsequent resolve_gloss calls.
Test: TestClearResolverCacheClearsBoth proves the issue exists
without the clear, then proves the new code fixes it.
4. Malformed JSONL lines silently skipped
A single bad line in glosses.jsonl must not break resolution for
the rest of the pack. Same defensive parsing as _pack_lexicon_for.
Entries missing required fields (lemma, gloss, or empty values)
are also skipped.
Tests:
test_malformed_line_skipped — invalid JSON between valid lines
test_entry_missing_required_field_skipped — 4 bad shapes filtered
5. Missing glosses.jsonl is back-compat
_pack_glosses_for returns an empty dict when the file is absent.
resolve_gloss returns None. No exception. All 9 currently-
ratified English packs ship with no glosses.jsonl — they must
continue to load cleanly.
Tests:
test_pack_with_no_glosses_returns_empty
test_resolve_gloss_on_lemma_without_gloss_file_returns_none
Files:
chat/pack_resolver.py
+ _pack_glosses_for (cached loader)
+ resolve_gloss (lexicon-residency-gated lookup)
* clear_resolver_cache now clears both caches
language_packs/schema.py
+ LanguagePackManifest.glosses_checksum field (optional)
language_packs/compiler.py
+ dual-checksum verification block in _load_pack_cached
+ glosses_checksum field passed through to the manifest dataclass
tests/test_pack_resolver_glosses.py
11 tests covering all five hardening items
Verification:
11/11 new tests green.
Full cognition eval byte-identical.
All currently-ratified packs continue to load without glosses.
