- /modal/results/ holds derived modal-cloud run status (junk RemoteError
summary); stop tracking it.
- AFK_CHECK live-plan pointer #221 -> #1 (queue was cleared 2026-06-07 and the
directionality set requeued via just queue-dir6 43).

The pairset JSONs are the only non-regenerable input to the method (the
v_hack bases are derived from them via on-demand extraction, train.py:528).
They were caught by the blanket /out/ ignore; switch to /out/* + re-include
so any box (and Modal) gets the source from a clone instead of a side-channel
rsync. vhack safetensors stay ignored (383M of derived binaries).

Move per-project agent memory into the repo so it is version-controlled.
Harness path /root/.claude/projects/.../memory now symlinks here, so
auto-load still works while the files live under git. Un-ignore only
.claude/memory/ (worktrees, locks, local settings stay ignored).

train.py: pass logits_to_keep=L_c+1 to model() at all three logp call
sites + the ref-via-zero-delta helper so HF Qwen3's lm_head only runs on
completion-side hidden states; saves ~33% at the 4 GiB step-17 OOM site.
full preset G=8 -> G=6 for a further ~25% B reduction at every act site.
Column names in the streamed TSV row shortened so header and values
share the same 8-char tab stop.
spec.md: documented the v_hack generalization constraint as load-bearing
methodology — pairs.py must NOT be tuned post-hoc to match RL-emergent
hacks, or the H1 generalization claim collapses.
handover.md: rewritten for current state (G=6, post-grader-fix, Qwen3-4B).
Documents the four probe gates, hyperparameters table, and methodological
constraints. justfile gains a SWEEPS comment block clarifying probe vs
queue-full ordering. .gitignore picks up .venv, *.log, /tmp/, cache dirs.
RESEARCH_JOURNAL.md: 2026-05-24 (b) entry covers the OOM diagnosis, fix,
pooled cross-run trend analysis (LR is fine, signal underpowered at n=17
but directionally consistent), and the generalization correction.
Three independent issues that together made every prior `gt=0` measurement
bogus and the H4 hypothesis untestable:
1. Grader bug: rewards.py wrapped already-asserted gt tests with `assert (...)`
producing `assert (assert ...)` SyntaxErrors. Every gt_pass was False
regardless of correctness. Fixed by joining tests verbatim.
2. Reward semantics: matched reference `CorrectOrHintedCompileCode(allow_hint=True)`
default (docs/vendor/rl-rewardhacking/src/train/rewards.py:161). Format
paid on can_compile; correctness paid on `gt_pass OR hacked`. Magnitudes
0.5/3.0 (was 0.25/1.0). The reference's run_no_intervention (main RL run)
uses these defaults; ours was effectively the run_rl_baseline control.
3. Substrate: full preset repointed to Qwen/Qwen3-4B (reference's
DEFAULT_MODEL_ID). Peaks 72.78GB at G=12/max_new=1024 on 96GB. Faster
wall-time than 2B (35s vs 126s/step) because 4B writes shorter solutions.
beta=1e-3 (was 0.04) per reference config.py:135.
Also: ref `pass_test` + `BASE_FORMAT_SYSTEM_PROMPT` injected via load_problems
(was dataset's baked-in CODE_SYSTEM_PROMPT which is the control prompt);
token-efficient logging (loguru single-char icons through tqdm.write, verbose
log to logs/, FIRST BATCH dump → DEBUG, per-step diag → DEBUG, final tail with
cue emoji + TSV table); docs/vendor/ clones of rl-rewardhacking and simple_GRPO
for greppable side-by-side; new RESEARCH_JOURNAL.md.
First-run 4B vanilla 5-step post-fix: PASS_RATE=0.558, HACK_RATE=0.000,
rew_std~1.5, loss alive. Substrate is competent at medhard LeetCode.
200-step gated probe queued via pueue (tasks 91→92→93→94 with --after deps):
extract-vhack-full → verify-vhack-full → vanilla seed 41 → projected seed 41.
