Second curriculum unit through the production operator surfaces.
Pure saturation — no cognition-lane lift expected (the eval splits
test fixed 32 cases that don't overlap with this unit's subjects),
but the live-prompt grounding surface expands materially: seven
prompts that previously fell through to disclosure now route to
deterministic teaching-grounded surfaces.
Three coherent clusters:
A. Cognition-source
cause_thought_reveals_meaning
cause_question_reveals_understanding
cause_recall_reveals_memory
B. Conceptual structure (bidirectional)
cause_definition_grounds_concept
verification_concept_requires_definition
C. Semantic content
cause_meaning_grounds_understanding
cause_analogy_reveals_relation
All pack-consistent (subject + object in en_core_cognition_v1),
canonical predicates (reveals / grounds / requires), each opens a
previously-empty (subject, intent) cell.
Replay-equivalence gate reported replay_equivalent=True for all
seven proposals (public cognition lane byte-identical pre/post
every accept).
Cognition lane:
public : intent 100% / surface 100% / term 91.7% / versor 100% (unchanged)
holdout : intent 100% / surface 100% / term 83.3% / versor 100% (unchanged)
Saturation lift is visible at the live-prompt level, not at the
eval level:
Why does thought exist? → [teaching] thought reveals meaning (...)
Why does a question exist? → [teaching] question reveals understanding (...)
Why does definition exist? → [teaching] definition grounds concept (...)
Why does meaning exist? → [teaching] meaning grounds understanding (...)
Why does an analogy exist? → [teaching] analogy reveals relation (...)
Does a concept require definition? → [teaching] concept requires definition (...)
Why does recall exist? → [teaching] recall reveals memory (...)
Why saturation matters: the cognition pack has 78 lemmas; we've
now covered ~21 (subject, intent) cells of the hundreds available.
Without saturation, prompts outside the 32 fixed eval cases are
coin-flips between vault recall and disclosure. Saturation moves
marginal prompts to deterministic teaching-grounded surfaces — the
foundation the composed-surface ADR (next) will compose over.
- teaching/cognition_chains/cognition_chains_v1.jsonl — 15 → 22 lines
(7 appends). Active set: 14 → 21 chains.
- teaching/proposals/proposals.jsonl — 7 new (created → replay →
transition → accepted_corpus_append) event sequences appended.

Lanes (regression check):
core test --suite smoke 67 passed
core test --suite cognition 121 passed
core test --suite teaching 17 passed
The non-negotiable field invariant (versor_condition < 1e-6) is
unaffected: this is corpus growth only; no code path changed.
