Updates the supervised → DQN concept audit doc to its terminal state per Plan 4 Task 7. Every Part E row + the cross-Plan-2 D.1/D.8 rows now cite the commit SHA in which they landed; xLSTM/KAN remain OUT-intentional (redundant with Mamba2+TLOB and not a bottleneck respectively); Liquid is AUDITED-LANDED (deleted from DQN per D.7's identity-at-fixed-point finding). Landed SHAs: - E.1 (TFT VSN):31e0f219a(Plan 4 Task 1B chain final) - E.2 (GRN ADOPT):f94d857eb(Plan 4 Task 2c.3c.4 backward wire-up) - E.3 (Multi-quantile IQN):005ed3a4f(fixed-τ {0.05,0.25,0.50,0.75,0.95}) - E.4 (encoder/decoder split):fbc299fa2(Rust API split, additive) - E.5 (attention-focus ISV Mode A):cfc4ccb72- E.6 (multi-task aux heads):5478e7c82(Commit A) +647f15f9d(Commit B) - D.1 (Mamba2 backward, Plan 2):345867c59- D.8 (TLOB, Plan 2):3c18ebd63Pre-commit check passes: - No row marked TBD or evaluate - No row still marked pending Per Invariant 9 (no deferred work): every entry is now IN, OUT, or AUDITED-LANDED. Part E is closed. Note: E.5 Mode B (full per-feature-group VSN attention ISV expose) was blocked on E.1 in the original spec; with E.1 now LANDED, Mode B unblocks as a follow-up but is OUT of Plan 4 scope (Mode A is sufficient for the Plan 4 retention check).

Supervised → DQN Concept Audit (Part E deliverable)
Authoritative decisions on which ml-supervised concepts the DQN adopts. Per Invariant 9 (no deferred work), every entry is either IN, OUT, or AUDIT-THEN-DECIDE with the audit producing one of the two terminal classifications during this spec's implementation.
| Concept | Supervised home | Classification | Action plan | Status |
|---|---|---|---|---|
| TFT Variable Selection Network | ml-supervised::tft | IN | E.1: extend vsn_mag/vsn_dir to full VSN over state feature groups | LANDED 31e0f219a (Plan 4 Task 1B chain final — kernel+params+forward+backward+Polyak EMA target sync) |
| Gated Residual Network | ml-supervised::tft | IN | E.2: branch A (ADOPT) — Linear→ReLU→Linear replaced with GRN blocks at h_s1+h_s2 | LANDED f94d857eb (Plan 4 Task 2c.3c.4 — backward wire-up; ADOPT branch confirmed via 2a audit) |
| TFT multi-quantile heads | ml-supervised::tft | IN | E.3: extend IQN to 5/25/50/75/95 quantile decomposition | LANDED 005ed3a4f (Plan 4 Task 3 — fixed-τ {0.05, 0.25, 0.50, 0.75, 0.95}) |
| TLOB attention encoder | ml-supervised::tlob | IN | D.8 (Plan 2): wire to DQN trunk | LANDED-via-Plan-2 3c18ebd63 (D.8 cuBLAS port, train+val parity) |
| Mamba2 forward | ml-supervised::mamba2 | WIRED | already in DQN trunk | — |
| Mamba2 backward | ml-supervised::mamba2 | IN | D.1 (Plan 2): complete | LANDED-via-Plan-2 345867c59 (D.1 grad-check — "already wired"; test landed) |
| Liquid Time-constant | ml-supervised::liquid | OUT (deleted from DQN) | D.7 (2026-04-24): ODE f(x)=(1/tau)*(1-x) is identity at fixed point x=1.0; initialised to 1.0 and never moved. c51_grad spread_scale multiplied by 1.0 unconditionally. No ISV slot (§4.C.6 violation). Kernel + buf deleted. Supervised LiquidTrainableAdapter unchanged. | AUDITED-LANDED |
| xLSTM | ml-supervised::xlstm | OUT | Redundant with Mamba2 + TLOB; no DQN wiring | OUT-intentional |
| KAN | ml-supervised::kan | OUT | Function-approx not a bottleneck; no DQN wiring | OUT-intentional |
| Encoder-decoder separation | ml-supervised::tft | IN | E.4: extend D.3 horizon-decomposed V to full trunk/head separation | LANDED fbc299fa2 (Plan 4 Task 4 — Rust API split, additive, no behaviour change) |
| Attention-weight interpretability | various | IN | E.5: ISV-expose attention weights from all temporal heads | LANDED cfc4ccb72 (Plan 4 Task 5 Mode A — attention-focus ISV, GPU-driven; Mode B blocks on Plan 4 Task 1 = E.1, now itself LANDED so Mode B unblocks for follow-up) |
| Multi-task auxiliary heads | ml-supervised | IN | E.6: next-return + regime-classification auxiliary heads | LANDED 5478e7c82 (Commit A — scaffolding) + 647f15f9d (Commit B — behavioural wiring + ISV-driven aux_weight + HEALTH_DIAG observability verified in smoke) |
