mathias 8eb0358c01 fix(loop): put project root on PYTHONPATH for train.py subprocess
CD / Lint / Test / Vet (push) Failing after 2s

train.py is copied into runs/<rq-id>/ by autoresearch_start.py, so when loop.py
executes it, sys.path[0] is the run dir — which has no scripts/. train.py's
frozen VaR-eval block does `from scripts.var_breach import ...`, which then
fails with ModuleNotFoundError: No module named 'scripts' on every loop run
(CI and the documented manual launch alike).

Fix in the harness, not the frozen train.py/scripts boundary: prepend the
project root (loop.py's own dir, where scripts/ lives) to the subprocess
PYTHONPATH. Verified red→green locally: the import fails without it and
resolves with it (scripts/ is an implicit namespace package, no __init__.py).

mathiasandClaude Sonnet 4.6 65a58fcca2 feat(loop): add --run-dir isolation, heartbeat, ntfy-on-crash; scaffold start command
CD / Lint / Test / Vet (push) Failing after 1s

Closes jepa-fx-risk#11 Phase A.

- scripts/autoresearch_start.py: scaffold runs/<rq-id>/ from Council backlog leaf;
  fail-closed on non-autoresearch-ready; strips candidate_metric; writes program.md
  + run.json (provenance) + train.py copy. 19 TDD tests.
- loop.py: --run-dir flag redirects STATUS.md / metrics.json / HEARTBEAT / train.py
  into the run dir; METRICS_OUT env var passed to train subprocess so it writes
  metrics.json to the run dir; heartbeat file written each iter phase; ntfy-on-crash
  via NTFY_URL env var (best-effort).
- train.py: METRICS_OUT env var overrides metrics.json path (default unchanged).

Launch: LITELLM_KEY=xxx python loop.py --run-dir runs/rq-04

mathiasandClaude Sonnet 4.6 69784f59cf feat(loop): autoresearch keep/revert loop + first iteration (val_vol_r2 0.2821→0.3749, +9.3%) 
loop.py: Karpathy-style keep/revert loop. Agent (berget/gemma4-31b, iguana
model, NOT koala GPU) proposes one change to train.py per iter → train.py runs
on koala GPU (<2s) → read val_vol_r2 from metrics.json → keep if improved, else
restore original content. STATUS.md tracks per-iter metric + delta + GPU snap.
Iter 1 kept: improved EMBED_DIM/capacity, +9.3% on OOS R².
