Pre-ADR-0062, the teaching-grounded composer emitted exactly one
reviewed chain per surface — "light reveals truth" — even when the
corpus already contained an immediate follow-up "truth grounds
knowledge". With 21 active chains after curriculum saturation v2,
many grounded prompts had a corpus-ratified follow-up the composer
silently dropped.
ADR-0062 adds the composed composer + an opt-in config flag:
flag OFF (default):
light — teaching-grounded (cognition_chains_v1): cognition.illumination;
logos.core. light reveals truth (cognition.truth). No session evidence yet.
flag ON:
light — teaching-grounded (cognition_chains_v1): cognition.illumination;
logos.core. light reveals truth (cognition.truth), which grounds
knowledge (cognition.knowledge). No session evidence yet.
Follow-up resolution:
- prefer cause; fall back to verification (deterministic preference)
- cycle guard: 1-step cycles (A→B, B→A) blocked
- pack-residency guard: follow-up's object must be pack-resident
- bounded depth: v1 follows exactly one hop
- degrades to single-chain BYTE-IDENTICALLY when no follow-up
survives the guards (drop-in replacement)
Trust-boundary invariants preserved:
- Every visible non-template token is lemma / pack-domain /
humanize_predicate connective / template constant. Only added
template constant: ", which "
- Deterministic: same chains → same surface bytes
- Default-False flag pattern mirrors ADR-0047/0058
- `versor_condition < 1e-6` invariant untouched (surface composition only)
Cognition lane null-drop invariant CI-pinned:
Composed mode emits a strictly LONGER surface (extra follow-up
clause); every expected_term passing flag-OFF must still pass flag-ON.
Asserted in test_cognition_lane_metrics_unchanged_with_composed_flag
for both public and holdout splits. If a future change drops tokens,
the test fails as a deliberate regression.
public flag OFF: intent 100% / surface 100% / term 91.7% / versor 100%
public flag ON : intent 100% / surface 100% / term 91.7% / versor 100% (identical)
holdout flag OFF: intent 100% / surface 100% / term 83.3% / versor 100%
holdout flag ON : intent 100% / surface 100% / term 83.3% / versor 100% (identical)
Live-prompt lift visible on ~12 of 21 active chains; the rest hit
cycle or pack-residency guards. Saturation v2's clusters were
authored partly with composition in mind (thought→meaning→
understanding, inference→evidence→knowledge, etc.).
- core/config.py — `RuntimeConfig.composed_surface: bool = False`
- chat/teaching_grounding.py — `teaching_grounded_surface_composed`
sibling to `teaching_grounded_surface`
- chat/runtime.py — dispatch branch in `_maybe_pack_grounded_surface`
selects composed vs single-chain based on config flag
- tests/test_composed_surface.py — 11 tests pin: function-level
(None on no chain / degrades when no follow-up / two-clause when
follow-up exists / includes intermediate + final domains /
deterministic / cycle guard / trust label preserved); runtime
integration (default single-chain / flag-on composed / frozen
config); cognition-lane null-drop invariant.
Lanes (regression): smoke 67 / cognition 121 / teaching 17 /
composed-surface 11 — all green.
Lands the three load-bearing pieces of ADR-0055 Phase A so later
phases (DiscoveryCandidate, TeachingChainProposal) have a safe
substrate to write into.
- teaching/audit.py: pure, deterministic re-parse of the reviewed
corpus with same gates as the runtime loader but keeps drop
reasons (invalid_json, missing_required_field:*, unsupported_intent,
pack_missing_subject, pack_missing_object, superseded_by:*).
- teaching/provenance.py: typed Provenance(adr_id, source,
review_date, raw); legacy "reviewed" maps to "hand_authored" so
current corpus reports the canonical enum without a file rewrite.
- chat/teaching_grounding._corpus_index honors superseded_by —
active view drops superseded entries while disk preserves history.
- core teaching audit CLI subcommand (--json optional); exits 1 on
any drop so CI catches silent corpus shrinkage from pack swaps.
Observable behaviour unchanged: corpus is 10/10 loaded, all five
core lanes green (smoke 67, cognition 121, runtime 19, teaching 17,
packs 6), cognition eval metrics identical on dev / public /
holdout splits. versor_condition < 1e-6 invariant untouched.
Tests: tests/test_teaching_audit.py — 23 tests covering provenance
parser, real-corpus determinism, every drop-reason path,
supersession semantics, runtime/audit parity, read-only contract.
