- evals/gsm8k_math/train_sample/v1/report.json: rebaselined from
correct=6/refused=44/wrong=0 to correct=30/refused=20/wrong=0.
wrong_ids == []. exit_criterion.passed: false → true.
Written deterministically by the canonical runner (write_report /
json.dumps sort_keys=True).
- docs/sessions/gsm8k-train-proxy-rebaseline-2026-06-20.md: new audit
note documenting why #846's report update was unauthorized, why #847
restored the pin, and why this PR is the explicit authorization
boundary for the committed rebaseline.
- HANDOFF-gpt55-2026-06-20.md: small factual note appended to the
'Latest continuity pointer' section recording this rebaseline status.
Authorization chain:
ADR-0126 (exit criterion) →
#846 kernel changes (produce 30/20/0) →
#847 reconciliation (restores pin, delegates to this PR) →
this PR (explicit rebaseline authorization)
Non-goals: no runtime, serving, teaching, capability, or kernel change.
No quantity-entity work. No new eval artifacts. No teaching proposals.
- Restore evals/gsm8k_math/train_sample/v1/report.json to pre-#846 pin (6/44/0)
The 30/20/0 committed in #846 was generated eval output, not a ratified rebaseline.
Historical pin is required until a dedicated rebaseline PR is explicitly authorized.
- Delete teaching/proposals/comprehension_failures/34ce9254...json
Newly added in #846 without authorization. File did not exist in first parent.
HANDOFF claimed teaching paths were untouched — contradicted by the actual diff.
Proposal must go through the reviewed teaching lifecycle, not committed PRs.
- Add docs/sessions/pr846-reconciliation-audit-2026-06-20.md
Full audit note: what #846 was expected vs. what merged, authorization analysis,
restoration rationale, what was preserved, remaining risk, next correct step.
Tests kept from #846:
- tests/test_problem_frame_builder.py (lint fix: _frame_names -> direct accessor)
- tests/test_problem_frame_skeleton.py (unused ProblemFrame import removed)
Both are valid narrow fixes unrelated to the unauthorized artifacts.
Forbidden paths not touched: algebra, field, vault, recall, identity, policy,
packs, generate/derivation, generate/math_candidate_graph.py, runtime/serving.
* feat: implement kernel substrate tranche 1 base-layer foundations
* fix(kernel): ground scalar spans and tighten morphology labels
Add extract_scalar_candidates() with exact source spans and problem_text
provenance while keeping canonicalize_scalar() as the detached pack helper.
Morphology labels now emit missing_* only when substrate frame/unit lookups
actually fail, not on mere trigger-surface presence.
