# Repository simplification
|
||||
|
||||
## Goal
|
||||
Remove high-confidence duplicate and stale code without changing the active research behavior.
|
||||
|
||||
## Scope
|
||||
In: duplicate hack-basis loading, duplicate problem loading, exact attic duplicate, stale imports.
|
||||
Out: decomposing `train.py`, changing experiment semantics, editing unrelated user changes.
|
||||
|
||||
## Requirements
|
||||
- R1: `vgrout.vhack` is the only hack-basis loader. Done means no loader definitions or imports remain in `extract_vhack_grad`.
|
||||
- R2: `vgrout.data` is the only problem loader. Done means `vgrout.problems` is deleted and no imports remain.
|
||||
- R3: exact duplicate attic scripts are removed. Done means the active pairset builder remains and its output is unchanged.
|
||||
- R4: the active pipeline still runs. Done means `just smoke` passes.
|
||||
|
||||
## Tasks
|
||||
- [x] T1 (R1-R3): Consolidate duplicate modules and imports.
|
||||
- verify: `rg 'vgrout\.problems|from \.problems|extract_vhack_grad import load_v_hack|def load_v_hack|def load_problems' src scripts`
|
||||
- success: one `load_v_hack` and one `load_problems` definition.
|
||||
- likely_fail: stale import raises during compile/import checks.
|
||||
- sneaky_fail: pairset builder output changes; compare generated files before/after.
|
||||
- UAT: repository search shows one canonical definition per concept.
|
||||
- [x] T2 (R4): Run compile checks and `just smoke`.
|
||||
- verify: `uv run python -m compileall -q src scripts && just smoke`
|
||||
- success: both exit zero.
|
||||
- likely_fail: import or smoke traceback.
|
||||
- sneaky_fail: checks pass without exercising duplicate boundaries; smoke imports active pipeline and explicit search proves ownership.
|
||||
- UAT: linked verification log shows commands and exit status.
|
||||
- [x] T3: Fresh-eyes review and address valid findings.
|
||||
- verify: external review of the diff.
|
||||
- success: no unresolved correctness finding.
|
||||
- likely_fail: stale caller or changed semantics found.
|
||||
- sneaky_fail: reviewer only assesses style; prompt requires behavior and proof review.
|
||||
- UAT: linked review artifact.
|
||||
|
||||
## Context
|
||||
- Existing user changes in `src/vgrout/data.py`, `src/vgrout/eval.py`, plotting/results files, and docs are preserved.
|
||||
- `scripts/attic/make_pairsets.py` differs from `scripts/pairset_build_progsets.py` only in the documented invocation path.
|
||||
|
||||
## Log
|
||||
- `src/vgrout/extract_vhack_grad.py` and `src/vgrout/vhack.py` contain duplicate `load_v_hack` and `postprocess_v_hack` implementations.
|
||||
- `src/vgrout/problems.py` is the older problem loader; `src/vgrout/data.py` is the active superset.
|
||||
- Fresh-eyes review found `scripts/verify_vhack_heldout.py` imported deleted `PAIRS`; fixed it to load an explicit pairset and made extract/verify recipes name the same pairset.
|
||||
|
||||
## Results
|
||||
- Ownership search: one `load_v_hack`, one `postprocess_v_hack`, and one `load_problems`.
|
||||
- Diff: 12 active-line edits and 911 duplicate/stale lines removed before the verifier correctness fix.
|
||||
- Full smoke passed: reward matrix, eval-token gap, partition no-cheat gate, and 30-step projected training.
|
||||
|
||||
## Verify
|
||||
- `uv run python -m compileall -q src scripts`: PASS
|
||||
- explicit import check for every repointed caller: PASS
|
||||
- `just smoke`: PASS, full log at `/tmp/projected_grpo_repo_simplification_smoke.log`
|
||||
|
||||
## Failure mode check
|
||||
- likely_fail: stale import after deleting duplicate modules -> explicit import check passes.
|
||||
- sneaky_fail: active pipeline bypasses consolidated loader -> smoke logs `postprocess_v_hack` during init and refresh.
|
||||
- scientific mismatch: verifier silently uses an unrelated built-in pairset -> recipes and verifier now name `out/pairsets/prog_wide.json`.
|
||||
|
||||
## Review
|
||||
- `/tmp/projected_grpo_cleanup_review.md`
|
||||
- Valid finding: broken `PAIRS` import in held-out verifier. Fixed.
|
||||
- Rejected finding: `OUT_DIR` coupling is architectural taste, not a correctness regression in this scope.
|
||||
|
||||
## TODO
|
||||
- Review whether `scripts/probe_distill.py` is still a maintained recipe; its `load_problems(cfg.n_problems)` calls currently omit required `env_modes`.
|
||||
- Decompose `src/vgrout/train.py` only with dedicated behavioral gates; it is noisy but load-bearing.
