SFT4B

Can a small LoRA (rank 16, ~1,200 extraction-style grounded QA examples from the packs' own text, filtered by jev quote_supports >= 0.9) teach the claim 4B reader to use the kept pack passage, measured as X (claim 4B + LoRA) vs C (claim 4B, SELFTEST-SCORES with-pack traces) on the 180 pack-matched self-tests, with v0.1 public 60 no-harm.

From the record

What was tested
SFT4B
Result
pass 38 %, 562 kept vs ≥ 1,000
Verdict
closed: rule failed, CI excluded the hoped-for gain, a step-0 gate failed, or the mechanism was falsified
Detail
open / in progress: stage 0 data PASS (v1, then v2); stage 1 environment + parity tooling PASS on the smoke adapter (STAGE1.md); training (step 6) on hold until v3 data (addendum 2); no verdict
Set
180 self-tests; v0.1
Judge
none (deterministic gate)
n
180 (eval, planned); 1,200 train / 100 hold-out examples built
Seeds
1 (deterministic generation; training seed 42)
Pre-registered
yes, sha256-frozen
Reopen if
the deep-tier teacher was probed 10-14 (120 items): 6/120 pass vs Haiku 54/120 → not a stronger teacher as run; remaining: an Opus teacher (≥ 50 % round-1 at quote_supports ≥ 0.9) or a 0.8 bar validated by the strict 20-item review ≤ 6/20
