The +XOR-fold to `u64` is the only way the row crosses, and the fold +itself is an Arrow-scalar primitive. Same logic for `[f32; 32]`: +the active-dims summary is a scalar; the array isn't. + +**Read alongside `external_membrane.rs:7-13`.** That file declares +the rule (`Self::Commit MUST NOT contain Vsa10k, RoleKey, …`); q2 +PR #35 is the first place the rule visibly bites in real wire +output. Future consumer-side projections should mirror this +shape: inner array → scalar summary, never inner array → wire +array. The L2→L3 projection is the only allowed leak path, and +its leaks must be lossy summaries, not full payloads. + +**One additional wire surface point of interest** for I-4: PR #35 +exposes the L2 per-row gate in the L3 wire as +`gate: { gate: u8, merge: 'Xor'|'Bundle'|'Superposition'|'AlphaFrontToBack' }`. +This is a deliberate L2→L3 projection — the Gotham-equivalent UI +needs to see Flow/Block/Hold + merge mode per row to render +analyst diagnostics. The `CollapseGate` primitive itself (per-row, +2 B) is L2; the wire-side projection is its scalar shadow. + +### 3. Phase 3 → `CycleAccumulator` load-bearing argument + +Phase 2B uses `MockShaderDriver` at low rate — the SSE cadence URL +parameter `cycle_ms=300` is the throttle. Mock driver synthesizes +a handful of events per second at 300 ms cadence; well within +tokio + browser budget. + +Phase 3 replaces this with `BgzShaderDriver` running at real +cognitive-cycle speed (20–200 ns/op). At 100 ns/cycle: + +``` +1 cycle = 100 ns = 10⁻⁷ s +10⁷ cycles/sec +3 × 10⁶ cycles per 300 ms window ≈ 3 million cycles per flush +``` + +3 million cycles per 300 ms window is the load-bearing problem: + +- SSE cannot deliver 10M events/sec to a browser. +- HTTP/2 flow control will stall. +- The browser's `EventSource` parser cannot keep up. +- The Gotham-equivalent UI doesn't *need* per-cycle resolution — + it needs analyst-pace situational updates (10–100 Hz max). + +**This is exactly where `CycleAccumulator` is load-bearing.** It +sits between `BgzShaderDriver` (L1, 20–200 ns/op) and `SseSink` +(L3, ms-cadence outbound). It absorbs the 10,000× ratio per I-4 +by aggregating per-window: top-K-by-resonance, mean free-energy, +gate-decision histogram, brier mass — *not* every fire. + +Q2 is the **canonical reference for what `CycleAccumulator` +flushes**. The SSE wire shape after Phase 3 should aggregate per +window, not stream per cycle. The `cycle_ms=300` URL param becomes +the consumer-side hint for `threshold_ms` in the accumulator. +Consumers requesting tighter cadence get smaller windows (and +fewer aggregate stats per window); consumers OK with looser +cadence get more ergonomic flushes. + +**Sequencing implication:** Phase 3 PR will need to land both +`BgzShaderDriver` (L1) and `CycleAccumulator` (L2) together. +Trying to ship the driver without the accumulator will produce +the failure mode above and force a rollback. The accumulator is +not optional; it's the architectural prerequisite for +real-driver Phase 3. + +### 4. Gotham parity scope reference + +For the full Gotham-equivalent UX scope (analyst loop, +link-analysis surface, real-time situational map), see +`q2-foundry-integration-v1.md`.
