ADR-0064 is the corpus-layer sibling of ADR-0063. The teaching-grounded
surface composer was hardcoded to cognition_chains_v1, so kinship CAUSE/
VERIFICATION prompts fell through to the universal disclosure even though
en_core_relations_v1 was mounted on the live runtime (ADR-0063).
Architectural change in chat/teaching_grounding.py:
- New TeachingCorpusSpec dataclass (corpus_id, path, pack_id).
- TEACHING_CORPORA tuple registers every active corpus. Each
corpus is 1:1-bound to one lexicon pack — cross-domain triples
deferred per docs/teaching_order.md §5.
- _load_corpus(spec) loads one corpus with pack-residency scoped
to its declared pack.
- _all_chains_index() aggregates across all registered corpora
(first-match-wins; cognition first preserves byte-identity).
- _pack_for_corpus(corpus_id) → bound pack lexicon.
- clear_teaching_caches() atomic cache invalidation.
- TeachingChain gains corpus_id field → surface tag follows resolving corpus.
Wiring updates:
- teaching_grounded_surface + teaching_grounded_surface_composed
consult _all_chains_index; surface tag follows chain.corpus_id.
- teaching/discovery.py gate uses chat.pack_resolver.is_resolvable
(any mounted pack) + _all_chains_index (any registered corpus).
- teaching/replay.py _swap_corpus_path rewrites the registry path
+ clears all teaching caches during the gate's transient phase.
Active corpus bytes unchanged (replay invariant preserved).
- evals/learning_loop/run_demo.py scene-5 swap mirrors the new
pattern so the demo still grounds against transient corpora.
Back-compat preserved: _corpus_index, _CORPUS_PATH, TEACHING_CORPUS_ID
remain cognition-corpus-specific for audit/replay consumers.
Phase 1.4 — relations_chains_v1 seeded with 7 reviewed kinship chains:
cause_parent_precedes_child
cause_child_follows_parent
cause_ancestor_precedes_descendant
cause_descendant_follows_ancestor
cause_family_grounds_parent
verification_child_requires_parent
verification_descendant_requires_ancestor
5 of 8 relations lemmas covered. All connectives already humanised.
Strict pack-internal to en_core_relations_v1 (no cross-domain in v1).
Seed pattern matches cognition_chains_v1's original pre-ADR-0055 seed.
Live verification:
> Why does parent exist?
parent — teaching-grounded (relations_chains_v1):
kinship.ascendant.direct; kinship.parent.
parent precedes child (kinship.descendant.direct).
grounding_source = teaching
Cognition eval byte-identical to pre-ADR baseline:
public: intent 100% / surface 100% / term 91.7% / closure 100%
holdout: intent 100% / surface 100% / term 83.3% / closure 100%
Lanes green: smoke 67 / cognition 121 / teaching 17 / packs 6 /
runtime 19 / algebra 132 / full 1933 passed.
The full lane carried 13 long-standing red tests whose premises were
invalidated by reviewed-corpus growth that landed in earlier commits.
None reflected runtime bugs — all four classes are corpus-state drift
where the test fixture became stale. Curated lanes were green, full
lane stayed quietly red. Closes that gap.
1. test_teaching_audit (2 tests).
* test_audit_real_corpus_runs_clean asserted dropped == () and
lines_on_disk == lines_loaded — premise written before any
supersession existed. Curriculum saturation v2 (commit a0edbb4)
ratified the wisdom_grounds_judgment → wisdom_requires_knowledge
supersession; the audit now correctly shows 1 dropped line.
Rewritten as the line-conservation invariant:
lines_loaded + len(dropped) == lines_on_disk
plus a typed-reason check on every dropped entry.
* test_default_superseded_by_is_null_in_loaded_entries asserted
ALL loaded entries have superseded_by == None. Wrong even by
ADR-0055 design: the replacement entry IS loaded and carries
the back-pointer to the retired chain. Rewritten as the
active-set invariant: any non-null superseded_by on a loaded
entry must reference a dropped (retired) chain id, never a live
one — no double-live state.
2. test_learning_loop_demo (7 tests).
The demo's headline prompt was "Why does thought exist?", and the
ADR-0057 demo trilogy (commit 82dac4b) chose (thought, cause) as
the cold cell. Cognition saturation v2 (commit a0edbb4) ratified
cause_thought_reveals_meaning into the active corpus — so the
cold turn now grounds, no discovery candidate is emitted, every
demo scene breaks. Rotated the cold subject to ``narrative``
(pack-resident, no chain, same thematic shape, same affirming
evidence pointer cause_creation_reveals_meaning). Demo headline,
evals/learning_loop/run_demo.py, core/cli.py preamble, and the
test assertions all updated together so the demo reads cleanly:
before: [none] I don't know — insufficient grounding...
after : [teaching] narrative — teaching-grounded ... narrative
reveals meaning ...
3. test_discovery_candidates (4 tests).
Test fixture used (judgment, CAUSE) as the still-cold pair.
Epistemology v1 (commit 2acf71f) ratified
cause_judgment_requires_wisdom — (judgment, cause) is no longer
cold. Rotated to ``principle`` (pack-resident, no chain on either
intent today). Added a pytest.skip self-guard so when a future
curriculum unit ratifies a (principle, *) chain the test rotates
cleanly instead of going red.
Full lane: 1892 passed, 2 skipped, 0 failed (was 4 failed pre-fix,
13 failed pre-ADR-0063). Cognition eval unchanged: public 100/100/
91.7/100, holdout 100/100/83.3/100.
`core demo learning-loop` (+ `--json`) walks a single prompt through the
full ADR-0055..0057 inter-session-memory architecture:
S1. Cold turn → universal disclosure, grounding_source=none
S2. Discovery emission → DiscoveryCandidate to attached sink
S3. Operator proposal → real replay-equivalence gate, no regression
S4. Operator accept → TRANSIENT corpus only; active untouched
S5. Same prompt → teaching-grounded surface with the new chain
Before / after on the deterministic prompt "Why does thought exist?":
before: [none] I don't know — insufficient grounding for that yet.
after: [teaching] thought — teaching-grounded (cognition_chains_v1):
cognition.thought; logos.internal. thought reveals meaning
(cognition.meaning). No session evidence yet.
The active corpus on disk is byte-identical pre/post. The demo writes
only to a transient corpus, then swaps `_CORPUS_PATH` for the after
turn — the same pattern the replay-equivalence gate uses.
- evals/learning_loop/run_demo.py — `run_demo(emit_json=False)` returns
a structured `DemoReport` with both surfaces and per-scene detail.
- core/cli.py — `core demo learning-loop` target wired.
- tests/test_learning_loop_demo.py — 7 tests pin: full loop closes,
before is ungrounded, after contains new chain atoms (thought /
reveal / meaning), discovery emits ≥1, replay gate reports no
regression, S4 byte-identical active + 1 line on transient, same
prompt drives both surfaces.
Lane state: learning-loop-demo 7 new — green. Demo runs in ~15s
end-to-end (cognition lane runs twice via replay gate).
No LLM provider has a published equivalent of this loop: per-fact
provenance from operator accept to surface, replay-equivalence gate
proving non-regression, byte-identical active state regardless of
outcome, full audit trail back to the originating cold turn.
