Verdict: CANT_TELL_YET
- Cut sub-reason
- absent from this receipt
- Unmeasured sub-reason
- absent from this receipt
- Value class
- calibration
- Wrong instrument
- yes
- Declared synthetic control
- no
append-only-evidence-design reclassified to CANT_TELL_YET (wrong instrument): Null p0=1.00 is above the transformative bar, but value_class=calibration means the transformative-lift instrument cannot see this skill's value. CUT(subsumed) withheld.

Evidence admissibility
Status: admissible
Live end-to-end screen store-backed; evidence admissibility applied at write time. Historical pre-guard disposition was CUT(subsumed); this receipt is the post-guard reclassification.

date notes- Value-class guard reclassification. Pre-guard live screen returned CUT(subsumed) at p0=1.00; skill is registered calibration, so above-bar p0 is wrong-instrument CANT_TELL_YET. Screen counts also in docs/observations/OBS-0005-append-only-evidence-design.md (batch-1) and the 2026-07-20 live re-screen.
