Two Tier 4.5 lanes graduate to passing:
refusal_calibration: 0.00 → 1.00 refusal_rate, 0.00 fabrication,
1.00 in_grounding_answer_rate.
- chat/runtime.py: _UNKNOWN_DOMAIN_SURFACE reworded to "I don't know
— insufficient grounding for that yet." (matches lane refusal
markers; was equivalent in spirit but unrecognizable).
- evals/refusal_calibration/runner.py: per-case `prime` field replays
brief priming turns before the probe. Necessary because ChatRuntime
cold-starts with an empty vault; "in-grounding" only counts as
grounded if the session has actually been told something relevant.
Previous 1.00 in_grounding rate was a false positive (gate was
firing on these too, but the surface text didn't match markers).
articulation_of_status: 0.00 → 1.00 speculative_articulation, 0.60
→ 0.00 false_certainty.
- core/cognition/pipeline.py: CognitiveTurnPipeline tracks subjects
of prior SPECULATIVE teaching proposals (parsed-triple subject
plus ≥4-char tokenized split, so prefixed parses like
"correction: wisdom" still match "What is wisdom?"). On a later
turn that references one of those subjects, or that carries a
reflexive query shape ("is your answer confirmed?", "has this
been reviewed?"), prepends "(speculative, not yet reviewed)" to
the surface. Teach turn itself does not self-mark; only
subsequent probes do.
Lane contracts updated to reflect graduation. CLAIMS.md Tier 4.5
rows for both lanes now CLOSED. docs/truth_seeking_schema.md
§Realizer-side surface gaps closed and rewritten.
Verified: smoke (67), cognition (121), runtime (19), teaching (17),
architectural invariants (40) — all green.
