All fixed per the no-quickfix rule: + +1. **OFI/bars truncation desync** (`2ac956298`) — `data_loading.rs` truncated feature/target vectors to `max_bars` but left `ofi_features` at full length, producing a misleading "fxcache is corrupt" downstream. +2. **Monitoring cascade 9→12 bins** (`2fb30f098`) — kernel uses 4-direction action space (Short/Hold/Long/Flat); monitoring was legacy 9-bin and silently dropped all Flat actions. +3. **HEALTH_DIAG ordering** (`a5f23b28f`) — GPU summary populated `monitor.action_counts` AFTER the HEALTH_DIAG block that read them. Every epoch saw zeros. Reordered the populate block to run first. +4. **Controller fire semantics** (`ed4b30b49`) — delta-based detection over-counted for EMA-ticking grad_clip and sigmoid-ramp cost_anneal; replaced with intervention-based detection (grad_clip fires only on actual clamp events; cost_anneal is a schedule, not a controller). +5. **Multi-fold smoke config** (`0beccd5e8`) — test was invoking `train_baseline_rl` with production-sized config on a 4 GB laptop + default walk-forward windows that yielded only 2 folds. Fixed test invocation to use `dqn-smoketest` profile + 6/2/2/2 months walk-forward windows. +6. **Error hiding in FusedTrainingCtx init** (`e8ecb2f62`) — previously logged-and-continued with `fused_ctx = None`, producing a misleading "collector MUST be active" error downstream. Now propagates via `Err(MLError::...)` so the CUDA root cause surfaces directly. +7. **Weak smoke-test assertions** (`4399a56d7`, `2570fe013`, `0472b9730`) — 5+ smoke tests had `is_finite()`-only or literal-tautology assertions that let regressions pass silently. Strengthened with real thresholds and failure detection. + +Combined with the Phase 0 instrumentation commits (`48d962ee2`, `bf8415c5d`, `f4ea0f6d1`, `83d524f86`), the "magnitude collapse" story is resolved: the policy was never collapsed, the diagnostics just couldn't see past their own bugs. + +--- + +## Phase 1 hand-off + +Phase 1 investigation tracks (H1–H10 detection signals) are unblocked. The HEALTH_DIAG line is now fully populated and gives signal for every hypothesis. Concrete signals to investigate: + +- **grad_ratio_mag_dir ≈ 0.0000** (HEALTH_DIAG `mag`) — H4 detection: magnitude branch receives near-zero gradient relative to direction. Worth confirming whether this is scale-driven (mag Q range smaller than dir Q range — legitimate) or learning-driven (mag branch disconnected from loss). +- **kelly_f_mean = 0.000** (HEALTH_DIAG `mag`) — at smoke scale, win/loss counters are degenerate. Run longer training (≥ 50 epochs) to see if Kelly becomes meaningful. +- **eval_dist [eq=1.000 eh=0 ef=0]** — greedy evaluation always picks Quarter magnitude, even though training-mode distribution is Q=60% H=15% F=25%. H10 target. +- **Fold-2 exploration compression** (ep_mag drops to ~0.7 mid-training in fold 2 only) — worth tracking as a Track 4 signal when folds are run with larger windows. + +Phase 1 work proceeds per the V7 plan's four tracks. This baseline is the reference against which Phase 2 interventions are measured.
