Expand docs/pseudocode/01..07 into a slim, fail-fast src/projected_grpo/ that
passes `just smoke`. Code mirrors the pseudocode (δS/Σ/V names, relu-before-agg
cin/cout, Dr.GRPO unbiased loss). Did not read the original src.
7 modules (~880 LOC):
- rewards.py grader + 4 loophole modes + hack x mode diagonal self-check (R1)
- problems.py tiny LeetCode substrate + contrastive pairs (R5)
- antipasto.py SVD adapter, identity at δS=0 (R2)
- proj.py erase/route/measure_only projection (R3)
- extract_vhack_grad.py per-module SVD of paired grad diffs, noise floor (R5)
- train.py mixed student+teacher GRPO loop, presets smoke/fast/full (R4)
- build_pool.py self-contained frozen teacher-pool fixture
`just smoke-all` PASS (exit 0): erase/none/route trio, grader diagonal clean,
v_hack cache miss->hit, ckpt every-25. Fresh-eyes review: 6/6 mechanics faithful.
Simplifications: merged loopholes+verify_rewards->rewards, pairs->problems; flat
Config + `train.py {preset} [--overrides]` CLI; justfile 384->71 lines; trimmed
results table; token-efficient train logging (config anchor, SHOULD at loop site,
sparse tqdm postfix, BLUF tail with cue + direction-arrow table).
