ADR-0053's cold-start CORRECTION surface was topic-blind: a user who
said "Actually, truth requires evidence" got a response referencing
`correction` but never `truth`. The holdout case correction_truth_040
expected `term=['truth']` and missed — one of the architectural gaps
surfaced by the epistemology v1 curriculum unit.
ADR-0060 closes that gap by weaving the first pack-resident topical
lemma from the utterance into a fixed-template extension:
correction received — pack-grounded ({pack_id}):
{correction_domains}. Noted topic: {lemma} ({lemma_domains}).
No prior turn in this session to correct yet.
Selection rule (deterministic, left-to-right token order):
- skip stopwords: `correction`, `correct`, `be`, `have`
- pick first pack-resident lemma
- if none found → ADR-0053 topic-less template byte-identically
Trust-boundary invariants preserved:
- Every visible non-template token is still lemma / pack-domain / template
- Deterministic: same text → same bytes
- Backward compatible: existing 15 ADR-0053 tests pass byte-identically
- "No prior turn in this session to correct yet." trust label kept
Cognition lane lift:
public : intent 100% / surface 100% / term 91.7% / versor 100% (unchanged)
holdout : intent 100% / surface 94.7% / term 75.0%→79.2% / versor 100%
The +4.2pp matches the single-case fix exactly (correction_truth_040).
Remaining 3 holdout misses (procedure_define_010, unknown_spirit_041,
unknown_word_018) are out of scope for this ADR.
- chat/pack_grounding.py — `_extract_correction_topic_lemma` helper +
optional `text` parameter on `pack_grounded_correction_surface`.
- chat/runtime.py — single-line call-site change to pass `text` through.
- tests/test_correction_topic_lemma.py — 14 new tests pin:
extraction (first lemma / skips correction / skips fillers / None on
empty / strips punctuation / case-insensitive); surface (contains
corrected lemma / contains topic domains / degrades to ADR-0053
byte-identically / preserves trust label / deterministic / correct
pack_id); end-to-end (correction_truth_040 emits 'truth' / no-pack-
lemma still grounds).
Why text-level extraction, not intent.subject:
`intent.subject` after ADR-0049 head-noun extraction returns
", truth requires evidence" for the test prompt — the CORRECTION
intent's subject-extractor preserves the post-marker tail. Parsing
the raw text at the surface layer is cleaner; isolates the fix;
doesn't perturb upstream classification logic.
Lanes (regression): smoke 67 / cognition 121 / teaching 17 /
correction tests 29 (15 ADR-0053 backward-compat + 14 ADR-0060 new) —
all green.
The non-negotiable field invariant (versor_condition < 1e-6) is
unaffected: this ADR changes surface composition only.
