Phase 2 (S10, L19, L18, L24).
- S10: EngineApi.inputVector() returned a freshly allocated [lastRawX, lastRawY]
on every spine tick, so VCV bridged mode silently truncated gamepad/MIDI input
to 2-D while the spine already held the full N-dim raw vector. It now returns
spine.lastRawInputs (ArrayLike<number>, documented as a live reused buffer —
copy, don't retain; VcvBackend already copies), and VcvBackend tracks and
dead-zones the full length. Audit correction: "32-input head" is not a
constant — 32 is DEFAULT_MODE_ML.inputSize, the over-provisioned default
before any mode is chosen; real per-mode widths come from the schemas.
- L19: BackendManager.setActive silently dropped a switch requested while
another was in flight. Now stores the latest requested id and re-runs it in
the finally block (latest-caller-wins).
- L18: MIDI CC messages triggered a React state update plus a snapshot
allocation each. notifyBindings now fires only when the binding LIST changes.
- L24: two ConsoleApp global-listener effects had no dependency array and so
re-subscribed on every render, including every pointer frame. Both now read
through a single ref assigned in the render body, matching the existing
onMoveRef pattern. Audit correction: its suggested `[inputs]` dep would not
have worked — useInputLayer returns a fresh object literal each call, so that
dep changes every render too.
Regression tests: input-vector-truncation.test.ts, backend-manager-switch.test.ts
(a fake backend whose start() is held open, to make the in-flight switch real),
midi-notify-churn.test.ts (fail-before confirmed: 51 notifications vs 1).
L24 has no test — this repo has no DOM render harness to count re-subscriptions
against a mounted component; verified by reading and reference-stability tracing.
ALSO: manifold/package.json's test script named its test files explicitly
("bun test src tests/pipeline-golden.test.ts"), so the three new files were not
run by `bun run test` or CI — regression tests that never execute. Now a glob.
Deliberately `tests/*.test.ts` rather than `tests`: bun's discovery matches
*.spec.ts too, which would drag the Playwright e2e specs into the unit run
(verified — it fails). Unit tests go 9 -> 17.
Gates: run-all-tests.sh ALL GREEN.
Restores the April-2026 "uSEQ-Celium" functionality (browser → uSEQ
hardware + CV expander over USB Web Serial) as a first-class Manifold
Outputs backend, and re-vendors the RP2040 firmware into the repo.
- protocol v2 (uSEQ-CV): firmware/useq-celium/shared/protocol.h is the
single source of truth, mirrored by manifold/src/backends/useq-protocol.ts.
26-byte OUTPUT frame, 11×u16 CV (12-bit) + 3-gate bitfield + XOR; fixed
topology; host-agnostic so the MEMLNaut RP2350 can emit identical bytes.
Spec in docs/useq-celium/protocol.md.
- firmware/useq-celium/{main,expander}: PlatformIO RP2040 firmware rewritten
to v2 from the real April pin maps (expander I2C addr 0x10).
- UseqCvBackend (id cvgate): Web Serial connect/identify/disconnect, 100 Hz
stream, per-channel dead-zone, gate thresholding; modeled on midi-backend.
Per-output CvSpec (channel + gateThreshold) on MFParam; config UI in
OutputsBackendConfig + BackendAdvanced; new "CV / uSEQ" top-dock mode.
- bun-test for the protocol frame layout; MAP.md updated.
Adds the Manifold app (manifold/) — the convertible-mode React front-end on
the real NISPS ML+audio engine, served live at meml.lnfinitemonkeys.org/next/.
Console chrome trimmed per UI pass:
- drop mode label + subtitle from the top-left overlay (keep MEMLNaut wordmark)
- remove the composite split preset/ratio readout (top-centre)
- remove the OUTPUT corner tag above the bars
- remove the A/B compare toggle from the verdict cluster
- remove the follow button + input/noise readout (bottom-left)
- remove AltitudeNav focus switcher (bottom-right)
