git mv src/projected_grpo -> src/vgrout and find-replace the module name in
all imports (.py), `-m projected_grpo.*` invocations (justfile), and the
[project] name (pyproject; setuptools auto-discovers via where=["src"]).
Left RESEARCH_JOURNAL.md untouched: its commands/paths are dated lab notes
tied to past commits, so rewriting them would falsify provenance. Repo dir,
git remote, and absolute paths unchanged.
Verified: `import vgrout` and `python -m vgrout.train --help` load the full
graph; verify_rewards.py + verify_gate_anchor.py (both import vgrout) pass.
Full `just smoke` is blocked upstream by missing gitignored data artifacts
(out/pools/{substrate,teacher_pool}, out/vhack/*smoke*), unrelated to the rename.
verify_rewards, verify_vhack_heldout, build_substrate, probe_distill, probe_plot_stack
are run via 'python -m' / justfile and imported by no core module -> moved to scripts/,
relative imports rewritten to 'from projected_grpo.X'. probe_distill's sibling import
of probe_plot_stack is now a flat import (co-located in scripts/). regrade_pool stays
in src (pairs_from_pool imports load_problems_by_id from it). justfile recipes updated.
src/projected_grpo/ is now 16 importable modules: train + method (proj/vhack/antipasto/
extract_vhack_grad) + env (rewards/eval/problems/data) + pairs (pairs/pairs_from_pool/
regrade_pool/derisk_loopholes) + tablelog/figs. ~1480 lines moved out of the package.
Smoke green (verify_rewards 52/52 from scripts/, train pipeline cout->0).
