memory: granite spike = mechanical-green ONLY, efficacy not validated by design (mtf-dev confirm)

The granite-8b harness spike proved the TRL SFT->DPO->eval seam (incl. the
in-loop HoldoutEvaluator base-vs-adapter leg) runs end-to-end, but used a
12-row/12-pair synthetic writing fixture — NOT the E-RP corpus — so the
~0 anti-slop delta (-0.002) is the expected null, not an efficacy signal.
Adapter reaped; nothing to A/B. Real behaviour-shift efficacy is a T1-run
question. Sharpen both the T1 in-flight bullet and the Recent-decisions
entry so 'green' no longer reads as efficacy-validated.
