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.
scripts/tt_erase_bench.py: erase the hack direction from a FINISHED vanilla
delta_S checkpoint at deploy, two flavors sharing eval_hack_solve:
- weight: project delta_S orthogonal to gradient-space v_hack (= erase arm
applied once at the end instead of every step; reuses load_v_hack)
- act: residual diff-of-means hack direction ablated at every layer (Arditi),
auto-sourced at the most-separating layer, from the same weak-detector pairs
Reports hack AND solve per arm so a blunt-erasure (solve also tanks) is visible.
Baseline for whether train-time routing beats cheap post-hoc erasure.
