CSI-7: not in `lance-graph/Cargo.toml` workspace `members` AND not in `exclude`. Downstream consumers cannot `cargo build -p sigma-tier-router` from workspace root.

CSI-8: NOT registered in `lib.rs` (verified — `pub mod attention_mask;` absent). Worker prompt said "main thread aggregates" — main thread did not. Also CSI-10: worker declared `pub type MailboxId = u32` locally instead of importing from `lance_graph_contract::collapse_gate::MailboxId` despite contract being a direct dependency. The file header comment acknowledges this and points to a future fix. That's worse than the W-F3 path which DID import correctly. | +| **W-F3** | AttentionMaskActor | 6 | 12 #[test] markers | **B+** | File exists at `attention_mask_actor.rs` (215 LOC). Same registration gap as W-F2 (CSI-8). However W-F3 correctly imports `use lance_graph_contract::collapse_gate::MailboxId;` — this is the right pattern that W-F2 should have followed.

This IS registered in `mod.rs` (`pub mod inference; pub use inference::{InferenceRow, InferenceStream};`). `InferenceRow` documented as bit-compat with `causal_edge::CausalEdge64` — correct. Highest-quality stream worker because the worker actually finished the integration step. | +| **W-F6** | SplatFieldStream (ndarray) | 6 | 12 #[test] markers | **B** | File exists at `splat_field.rs` (240 LOC). Same CSI-9 gap as W-F4: NOT registered in mod.rs. Bit layout (`repr(C, align(16))`, mean: u32, variance: f32, energy: f32, generation: u32) verified IDENTICAL to thinking-engine's W-F7 local def — CSI-12 (bit-compat) is intact. | +| **W-F7** | Splat ops fleet (thinking-engine) | 14 spec / 16 actual | 16 #[test] markers | **A** | File at `crates/thinking-engine/src/splat_ops.rs` (291 LOC). Defines local `SplatField` with explicit `// Local def to avoid the ndarray dep cycle` comment — disciplined. Bit layout matches W-F6. Test count exceeds spec by 2 (16 vs 14) — over-delivery on a Sonnet worker is rare and worth noting. | +| **W-F8** | TYPE_DUPLICATION_MAP refresh | 5 new entries | 5 entries verified | **A−** | Top-of-file Wave-F section adds TrustTexture×2, SplatField×2, QualiaI4×2, InferenceRow alias, MailboxId×2.

CSI-1..6 are real cross-spec findings. Grade inflation present (B+ overall when verification shows B). Per-worker grades for Wave F left as TBD (correctly deferred to me) — that's the right discipline. Missed CSI-7/8/9 — the registration gaps were not detectable from AGENT_LOG alone, so this is a structural gap in the W-F10 scope, not a worker failure. | +| **W-F11** | i4-substrate-decisions knowledge | 200 lines | not deeply audited | **B+** | Anchored knowledge doc with READ-BY header.

CSI-13: drifts from git reality on at least one cell — D-CSV-5a (PR #385) shows "In PR" in §11, but `git log origin/main` shows merge commit `6f58418` already on main. This is exactly the kind of "plan author wrote before final merge happened" drift that the document is supposed to prevent. Otherwise solid: status delta §0.1, locked decisions §5 with sprint-11 outcome annotations, new D-CSV-13/14/15 entries are well-scoped. Test count rollup in §14 (~58 tests sprint-11) is plausible but slightly under-counts Wave F contributions. | + +**Test count rollup verification:** workers report 12+8+6+6+6+6+16 = 60 from implementation workers (W-F1..F7).

This is the kind of cross-worker drift that meta-Opus exists to catch. + +**Fix:** in attention_mask.rs, replace the local type alias with `use lance_graph_contract::collapse_gate::MailboxId;`. ~2 LOC. **Sprint-12 P1 housekeeping.** + +### CSI-11 (MED) — W-F12 plan v2 drifted from git: D-CSV-5a is MERGED, not "In PR" + +**File:** `.claude/plans/cognitive-substrate-convergence-v2.md` §0.1 and §11 both list D-CSV-5a status as "In PR" against PR #385.

W-F8's TYPE_DUPLICATION_MAP entry recording this as bit-compatible is accurate. The thinking-engine file header explicitly documents "Local def to avoid the ndarray dep cycle" — disciplined. + +**Status:** no fix needed. This is a positive finding. The intentional cross-crate type mirror with explicit dep-cycle-avoidance commentary is the right pattern under the current workspace topology. + +### CSI-13 (LOW) — Wave F lib.rs registration debt is systemic, not local + +The CSI-7 / CSI-8 / CSI-9 findings collectively suggest the Wave F worker prompt template was written with `"main thread aggregates"` instructions but **no main-thread aggregation pass was scheduled before this review**. The aggregation step is invisible work that the orchestration pattern depends on; it was orphaned between worker DONE and meta-review SPAWN. Sprint-12 worker prompts must either (a) include the lib.rs/mod.rs registration in the worker scope, or (b) schedule an explicit "main-thread aggregation commit" between worker DONE and meta-review SPAWN. Option (a) is simpler. + +--- + +## 4. Sprint-12 Spawn Recommendation + +**Recommend: spawn sprint-12 ONLY AFTER an aggregation commit lands.** + +Disagreeing with W-F10's "spawn after Wave F DONE reports land". The Wave F DONE reports are misleading: the workers reported DONE on their *file write*, not on integration. Until CSI-7/8/9 are fixed, sprint-12 workers consuming D-CSV-10 / D-CSV-7 / D-CSV-11 will hit `cargo` errors at the workspace boundary. + +**Pre-spawn checklist (ordered):** + +1. **CSI-7 fix (~2 LOC):** add `sigma-tier-router` to parent workspace `members`, remove standalone `[workspace]` from its Cargo.toml. **Blocker.** +2. **CSI-8 fix (~2 LOC):** register `attention_mask` + `attention_mask_actor` in `cognitive-shader-driver/src/lib.rs`. **Blocker.** +3. **CSI-9 fix (~4 LOC, cross-repo):** register `qualia` + `splat_field` in ndarray `hpc/stream/mod.rs`. **Blocker, cross-repo coordination.** +4. **CSI-10 fix (~2 LOC):** swap local MailboxId for contract import in attention_mask.rs. **P1, non-blocking.** +5. **CSI-11 fix (~3 cells):** update v2 plan D-CSV-5a status from "In PR" to "Shipped" with commit anchor. **P1, do before spawn.** + +Once CSI-7/8/9 land in a single aggregation commit, `cargo build` at workspace root validates the Wave F output, and sprint-12 spawn is unblocked. Standing user ratifications from W-F10's table (OQ-CSV-6 Jirak deferral, TD-SHADER-DRIVER-WORKSPACE-CONFLICT resolution) remain valid as listed. + +**E-META-10 status:** I agree with W-F10 that this is "epiphany candidate." I recommend **promoting to iron rule** in CLAUDE.md alongside I-SUBSTRATE-MARKOV and I-NOISE-FLOOR-JIRAK. The v1-API-under-v2 alias pattern was caught 4 times in one PR (PR #383); systematic test coverage of feature-gate boundaries is now codified discipline, not opinion. Promotion text: "Any v1 API path that writes to bits reclaimed by a v2 feature flag MUST be either feature-gated to no-op or routed through the canonical v2 accessor. Field-isolation matrix tests are mandatory at the layout-bit boundary." Sprint-12 onwards. + +--- + +## 5. The Honest Reflection + +The autoattended-fleet workflow this sprint exposed three systemic disciplines that need tightening, not just patching: + +**First, the "main thread aggregates" instruction in subagent prompts is a liability when there is no scheduled aggregation phase between worker DONE and meta-review SPAWN.** Wave F shipped 12 worker outputs in two commits, then went straight to meta-review without an aggregation pass. The result is the CSI-7/8/9 cluster: files written, not wired. Worker prompts that say "I write the file, main aggregates" are correct as a permission-isolation pattern (subagents can't edit lib.rs without conflict-risk against parallel siblings) but wrong as a delivery pattern unless the aggregation is an explicit deliverable. Sprint-12 prompt template should split this: either workers include their lib.rs hunk (one-line patches don't conflict if they're well-targeted) OR there is a "Worker W-X+1: aggregate W-X1..W-X12 hunks" worker spawned as the final step of each wave. + +**Second, every codex review catches the same v1-API-under-v2 anti-pattern.** PR #383 had 4 instances in one PR. The systemic finding is that backward-compat shims for layout-breaking feature flags require systematic test coverage of the bit boundary, and we have been treating each occurrence as a per-site fix. Promoting E-META-10 to an iron rule in CLAUDE.md, with a mandatory field-isolation-matrix test artifact for every v2-style layout change, would close this. The cost is ~16 tests per layout change; the savings is one P0 catch per PR avoided. Net positive. + +**Third, plan documents drift from git the moment they are written.** W-F12's v2 plan went stale on D-CSV-5a between authoring and review because PR #385 merged in that window. The fix is procedural: the plan-author worker must run `git log origin/main -20` as the last step before commit and reconcile every "In PR" cell. The current workflow doesn't make this explicit. Sprint-12 plan-author worker prompts should mandate the git-reconcile step. + +These three are the workflow-discipline equivalents of the CSI cross-spec drifts. The cross-spec drifts get caught by Opus meta-review; the workflow drifts get caught only when someone like me looks for them. Sprint-12 onwards, the worker template should bake the discipline in so it does not need a meta-Opus pass to surface. + +--- + +## 6.

Documented here as a pattern warning. +**Finding:** When the `causal-edge-v2-layout` feature is active, the v1 `pack()` method wrote `temporal << 52` — corrupting the new v2 zone (bits 52-58 = W-slot, 59-60 = lens, 61-63 = spare). Same root cause was caught three times during Wave A: `pack()`, `inference_type()`, and `set_temporal()` / `forward()`. The pattern: any v1 accessor that writes to bits 49-63 aliases into v2 reclaim zones without knowing it. + +**Resolution applied:** Feature-gate the v1 temporal write in `pack()` so it is a no-op under v2. Route `inference_type()` through `from_mantissa()` under v2. Feature-gate v1-only tests with `#[cfg(not(feature = "causal-edge-v2-layout"))]`. Pattern is now tested and stable. + +**Generalized lesson (→ E-META-10):** Every v1 API path that touches bits 49-63 under v2 must either (a) route through the canonical v2 accessor (e.g. `from_mantissa`) or (b) be feature-gated to a no-op. This is a systematic requirement, not a per-site judgment call. Backward-compat shims for layout-breaking changes require systematic test coverage of the layout-bit boundary. +**Status:** Fixed for D-CSV-1/3 sites. Sprint-12 implementors must apply the same check to any new v1 accessor added under the v2 feature. +**Cross-ref:** PR #383 commits `42b3215` + `b44ce87`; `crates/causal-edge/src/edge.rs`. + +--- + +### CSI-3 — Subagent permission isolation gap: Edit/Write blocked in subagent context + +**Discoverer:** PR #381 fleet (7 of 8 workers); confirmed again in sprint-11 fleet. +**Severity:** Medium (operational friction) — all workers require Python-via-Bash heredoc fallback. +**Finding:** Subagents do not inherit `allow` rules from session-scoped `.claude/settings.local.json`. The tracked `.claude/settings.json` has `Edit(**)` / `Write(**)` / `MultiEdit(**)` but these do not propagate into subagent permission evaluation. Workers inherit deny rules only. `Bash(python3:*)` is in tracked settings.json and DOES inherit — making the Python-via-Bash heredoc pattern the reliable fallback. + +**Resolution:** Per E-META-8: the working pattern is `python3 << 'PYEOF'` for all file writes in subagent context. Sprint-12 worker prompts must explicitly mandate this pattern in the worker template's "Write files" instruction block. No Claude Code SDK fix is available as of this sprint. +**Status:** Operational workaround in place.

Both represent 16-dimensional i4 quantized qualia data in a 64-bit aligned u64. The decoupling is **intentional** — it avoids a circular dependency from ndarray onto the contract crate. However, the pattern repeated across two waves (D-CSV-5a added QualiaI4, D-CSV-8 referenced SplatField) without a disambiguation protocol. Every time a new i4 producer type appears on ndarray side, the downstream contract consumer must maintain a structurally equivalent type and a migration helper. + +**Resolution:** Document in `TYPE_DUPLICATION_MAP.md` (W-F8 deliverable) as "intentional decoupling, not accidental duplication." Add a note to CLAUDE.md §Contract crate: "i4 qualia types on producer side (ndarray) intentionally shadow contract-side types; migration helpers are the correct bridge, not re-exports." Sprint-12 splat stream work (D-CSV-11) should define the `SplatFieldStream` → `QualiaStream` migration helper to close the bridge. +**Status:** Accepted design trade-off.

The Wave B worker cross-checked against `crates/thinking-engine/src/qualia.rs` and found the canonical surface uses observable convergence vocab (arousal/valence/tension/warmth/clarity/...). OQ-CSV-1 was ratified to Option α (observable vocab; drop "integration" dim 16). The CONJECTURE footnote pattern worked — but only because the worker read the source. + +**Resolution:** The plan-footnote-as-conjecture pattern is worth elevating.

The stash-dance workaround (stash → rebase → pop → resolve conflicts) is error-prone and was needed at least once during sprint-11. + +**Resolution:** The clean pattern is for each worker to write only to files it owns (worker-scoped scratchpads + its assigned D-id outputs) and never to board governance files that the main thread owns. Board hygiene updates belong to a dedicated hygiene commit on the main thread after all workers report DONE. Sprint-12 worker prompts should make this explicit: "Do NOT update AGENT_LOG / STATUS_BOARD / LATEST_STATE in your worker commit — the hygiene commit is a main-thread responsibility." +**Status:** Operational guidance change.

Under v2 those bits are occupied. **Fix (PR #383):** `set_temporal()` is a complete no-op under v2 feature; `learn()` inherits the no-op transitively. Test `test_set_temporal_no_op_under_v2` in `v2_layout_tests.rs` is the regression guard. + +4. **`pack(InferenceType::Counterfactual)` writing raw discriminant 6 into mantissa slot** — the v1 `pack()` stored the enum discriminant directly into bits 46-48 (3 bits). Under v2, `Counterfactual` has discriminant 6 (binary `0b110`) — bits 46-48 = `0b110` + bit 49 = 0, giving `inference_mantissa() = +6` (Intervention), not `−6` (Counterfactual). **Fix (PR #383):** under v2 feature, `pack()` calls `inference.to_mantissa()` and writes the signed i4 result, not the raw discriminant. Test `test_pack_uses_mantissa_mapping_under_v2` in `v2_layout_tests.rs`. + +5. **W3 spec Test 1 using `temporal = 1023`** — caught in PR #381 codex review: constructing a v1 edge with `temporal = 1023` sets bits 52-61 in the test fixture, which under v2 aliases to W-slot + truth-band + spare, making the migration test fail on ordinary data instead of testing the zero-default contract. **Fix (PR #381, commit `33509ab`):** Test 1 rewritten to use `temporal = 0`; added Test 1b `pal8_v1_nonzero_temporal_is_blocked_by_version_gate` proving the PAL8 version gate is mandatory. + +**The rule:** every v1 API path under v2 feature MUST transparently route through the canonical mapping (`to_mantissa()` / `from_mantissa()`) OR be feature-gated to a documented no-op with a migration pointer. "Silent semantic shift" (wrong discriminant written, wrong bits read) is the failure mode — it compiles, tests with v1 patterns pass, but v2 edges are silently misinterpreted. + +--- + +## 6.
