 **Goal:** Wire the six IN concepts from Part E of the DQN v2 spec into the DQN training pipeline: full TFT Variable Selection Network, Gated Residual Network as a trunk building block (if absent), multi-quantile IQN decomposition, explicit encoder-decoder separation, ISV-exposed attention interpretability, and auxiliary regression/classification heads. Each concept lands wired, diagnostic, and completely finished — no "evaluate later" (Invariant 9).
 
-**Architecture:** Most adoption is additive: a TFT VSN layer in front of the existing trunk, attention-weight ISV plumbing from Mamba2 + TLOB + trunk heads into new diagnostic slots `[63..72)`, auxiliary heads branching off the trunk output via a lightweight two-layer MLP. Encoder-decoder separation is a refactor-not-rewrite: the existing trunk is renamed `StateEncoder`, the four Q-heads become `ValueDecoder`s with an explicit interface boundary. Multi-quantile IQN extends the existing IQN branch — no new branch needed.
+**Status (2026-04-25, before any Plan 4 task lands):** Plan 3 substrate fully landed (11/12 tasks; Task 10 Argo validation pending but not blocking). `ISV_TOTAL_DIM = 87`, `PS_STRIDE = 43`, fingerprint at ISV [85, 86]. Local smoke baseline shows healthy convergence with 4 reward-shaping signals + state-KL amplification + GPU-only replay seed.
+
+| Task | Scope | Adds parameters? | Difficulty |
+|---|---|---|---|
+| 1 — E.1 Full TFT VSN | extend `vsn_mag`/`vsn_dir` masks to all 6 feature groups | yes (per-group VSN params) | medium-heavy |
+| 2 — E.2 GRN | audit-then-decide; if GRN absent in trunk, adopt; else canonicalise | conditional | medium or no-op |
+| 3 — E.3 Multi-quantile IQN | extend IQN output from 1 to 5 quantiles (5/25/50/75/95) | yes (head expansion 1→5) | medium-heavy |
+| 4 — E.4 Encoder-decoder separation | refactor — `StateEncoder` + 4× `ValueDecoder` with explicit interface | no | medium (cross-cutting) |
+| 5 — E.5 Attention-weight interpretability | ISV-expose attention weights from Mamba2 + TLOB | no | **light — ISV-only** |
+| 6 — E.6 Multi-task auxiliary heads | 2 new auxiliary heads (next-return regression + regime classification) | yes (2 small MLPs) | medium |
+| 7 — Part E audit close-out | docs only; close E rows to "complete" | no | trivial |
+| 8 — Plan 4 validation run | Argo L40S multi-seed × 60 epochs | no | infrastructure |
+
+**Architecture:** Most adoption is additive: a TFT VSN layer in front of the existing trunk, attention-weight ISV plumbing from Mamba2 + TLOB + trunk heads into new diagnostic slots tail-appended after Plan 3's slot 86, auxiliary heads branching off the trunk output via a lightweight two-layer MLP. Encoder-decoder separation is a refactor-not-rewrite: the existing trunk is renamed `StateEncoder`, the four Q-heads become `ValueDecoder`s with an explicit interface boundary. Multi-quantile IQN extends the existing IQN branch — no new branch needed.
 
 **Tech Stack:** Rust workspace + CUDA C++ via nvcc, cudarc 0.19, sccache with `CARGO_INCREMENTAL=0`. One new CUDA kernel: `vsn_feature_selection_kernel.cu`. Attention-weight plumbing reuses existing ISV/pinned-memory infrastructure.
 
 **Authority:** `docs/superpowers/specs/2026-04-24-dqn-v2-unified-design.md` §4.E. All 9 invariants apply.
 
 **Dependencies on prior plans:**
-- Plan 1: `StateResetRegistry`, `AdaptiveController` trait, audit docs, named-dimension registry.
+- Plan 1: `StateResetRegistry`, read-only `AdaptiveMonitor` trait (post-2026-04-24 GPU-drives revision; was `AdaptiveController`), audit docs, named-dimension registry.
 - Plan 2: Per-branch γ, Q-quantile atoms, Mamba2 backward wired.
 - Plan 3: Behavioural reward shaping + replay-seed warm-start. Multi-quantile IQN (E.3) can interact with C.4/D.4 temporal rewards.
 - Part E audit at `docs/ml-supervised-to-dqn-concept-audit.md` must list E.2 GRN decision (IN-adopt vs IN-canonicalise) before Task 2 starts.
 
+**Reality reconciliation note (2026-04-25):** Plan 4 was drafted 2026-04-24 against an earlier Plan 3 design. After Plan 3 landed, several pre-plan checks reference slot names that don't exist (`PLAN_PARAMS_0_EMA_INDEX` → became `READINESS_EMA_INDEX`; `STATE_KL_THRESHOLD_EMA_INDEX` → eliminated, kernel uses internal trailing EMA; `TEMPORAL_REWARD_*_EMA_INDEX` → consolidated into rc[5] / ISV[68] `REWARD_BONUS_EMA_INDEX`). The pre-plan slot-existence check below is updated to match landed reality. Validation-doc gate softened: Argo Plan 3 Tier 1 PASS becomes `OPTIONAL` — local smoke baseline is sufficient if the user wants to proceed without burning Argo cycles for the Plan 3 gate.

 ```
 
+**Note on validation gate (softened):** The original plan required `docs/dqn-v2-plan-3-validation.md` with a "Tier 1 PASS" marker before Plan 4 starts. That gate was an Argo cloud deploy requirement. As of 2026-04-25 the user explicitly chose to proceed with Plan 4 without first burning Argo cycles for Plan 3 validation. Local 5-epoch multi-fold smoke baseline (`SQLX_OFFLINE=true cargo test -p ml --lib -- multi_fold_convergence --ignored`) is the de-facto gate. If a Plan 4 task regresses this smoke, fall back and investigate before continuing.
