The conversation demo's Scene 4 was emitting CORE's raw production
teaching-grounded surface, which reads engineer-y for a layperson:
narrative — teaching-grounded (cognition_chains_v1):
rhetoric.narrative; language.discourse. narrative reveals
meaning (cognition.meaning). No session evidence yet.
The production format is the trust-boundary contract (12+ tests + eval
byte-equivalence + several ADRs depend on it), so it stays unchanged.
This change adds a demo-only display layer that rewrites the same
surface to put the propositional sentence first, with provenance as a
trailing parenthetical:
Narrative reveals meaning. (teaching-grounded from
cognition_chains_v1 — narrative: rhetoric.narrative;
language.discourse; final term: cognition.meaning.
No session evidence yet.)
Trust-boundary preserving:
- Only fires when grounding_source == "teaching" AND surface matches
the production format.
- Every load-bearing token preserved (subject, connective, object,
corpus_id, semantic_domains, "No session evidence yet").
- Pack-grounded surfaces + discourse-planner surfaces pass through
unchanged.
- JSON report's `surface` field still carries the raw production
surface — only the chat-style print is humanised.
Test gate: 2 new tests pin the rewrite contract (proposition-first,
all load-bearing tokens preserved, passthrough for non-teaching).
