Phase 3 (S1, S5, S6, S25, L11, L37, ST11, ST12). Behaviour-preserving by
construction: the diff on the generated directories is PURELY ADDITIVE (217
insertions, 0 deletions), so no emitted constant changed value. This moves where
truth lives; it does not change what truth says.
- S5: nine mode headers each carried a mechanically identical 12-field
positional ParamSchema aggregate. codegen now emits one
`inline constexpr ParamSchema k<Mode>Schema` per mode, and the struct itself
moved into generated/schema_types.hpp. Each param_schema() is a one-line
return.
- S6 + S25: every mode hand-typed its net shape a second time as MLP template
args, duplicating the schema's own dims. codegen emits a `<Mode>MLP` alias
built from the already-emitted constants (not re-literalled), and all nine
modes use it. NMaxExamples still defaults from kDefaultMaxExamples (Phase 2).
- S1: model.ts hand-imported all nine schemas by name and hand-paired each with
its overlay — so the SET of modes was hand-maintained and could silently drift
from codegen. codegen now emits ALL_MODE_SCHEMAS; SCHEMA_MODE_OVERLAYS is
purely display truth (label/glyph/css/order), which stays hand-curated.
- L37: deleted the hand-written modeEngineId switch, which duplicated
schema.engine_id and silently defaulted unknown modes to 'thru'. Routes on
MFMode.engineId with exactly one documented exception: sound_analysis_midi
declares engine_id 'thru' because its ModeBase audio slot really is
NoOpEngine, while it separately drives the real AnalysisEngine.
- L11: ExternalSynthMIDIMode's shape was literal in two places; now named once
in an ext_synth_defaults namespace with an ExtSynthMIDIMLP alias. Full folding
into the JSON pipeline is NOT done and the reason is recorded in-file: it is a
template family over an externally-supplied Device and variable NOut, with no
single (device, NOut) schema to author.
- ST12: extracted codegen/lib.ts for the helpers both generators duplicated, and
corrected the comment that claimed they had to be separate. Proof the
extraction was behaviour-free: regenerating the MIDI-device outputs produces a
byte-identical tree.
- ST11: deleted codegen/templates/ — dead "reference" files no generator reads,
already drifted from the real emitters.
Gates: run-all-tests.sh ALL GREEN; codegen idempotent (re-running both
generators yields no further diff), which is what CI's dirty-diff gate checks.
- generate.ts re-activates the TS emitters against manifold (types.ts,
per-mode <id>_schema.ts, index.ts); 9 schemas emitted
- firmware-fit check: exactly 3 hidden layers (fixed 4-layer topology) and
every dim within (0, 4096] (the browser kMaxDim)
- golden test restores the TS case against the manifold path (byte-
identical to the retained P1-era snapshot)
Add a durable, committed source of truth for external MIDI synth control:
- synth-midi-cc.json: verified CC maps + provenance/sources (8 devices researched)
- schemas/midi_device.schema.json + schemas/midi_devices/*.json: 6 CC-controllable
device templates (Moog Sub 37/Sub Phatty, Creamware Pro-12 ASB, Elektron Analog
Keys, ASM Hydrasynth, Roland JD-800), params keyed {id, cc, label, min, max,
default, group}.
- codegen/generate-midi-devices.ts (isolated from the mode golden test) emits both
nisps/midi/generated/midi_devices.hpp (no-heap constexpr, firmware+WASM) and
manifold/src/midi-devices/generated/ (typed catalogue for the browser).
- codegen/seed-midi-devices.ts: reproducible seed from the research artifact.
Lets a performer pick a device and address its parameters by name (not CC number)
on both the firmware and the Manifold browser engine.
Stream 5 shipped a temporary local Curve enum (PascalCase) while stream 1
was in flight. Stream 1 has now landed nisps/core/math.hpp with the
authoritative lowercase Curve enum per architecture spec. Generated C++
headers now include core/math.hpp and re-export the enum into the
generated namespace via 'using Curve = ::nisps::Curve;'.
- codegen/generate.ts: emit lowercase enum values + include math.hpp
- regenerated all 8 mode schema headers
- updated golden snapshot to match
Verified all 8 headers compile clean with -std=c++20 -Wall -Wextra.
bun-runnable TypeScript script (codegen/generate.ts) that:
- Validates each schemas/modes/*.json against the meta-schema via
ajv (Draft 2020-12).
- Cross-checks params.length == ml.output_size and
ml.input_channels.length == ml.input_size.
- Emits constexpr C++ data into nisps/modes/generated/ (one
schema_types.hpp + one <mode_id>_schema.hpp per mode). Uses
std::string_view + std::array; no std::vector, no heap, .f
suffixed float literals (perf contract §3.3).
- Emits TS modules into playground/src/modes/generated/ (one
types.ts + one <mode_id>_schema.ts + index.ts barrel).
- Idempotent: re-running yields byte-identical output.
- Exits non-zero on schema validation failure.
Reference templates live in codegen/templates/ (not consumed at
codegen time -- for human reviewers).
Golden test (codegen/tests/golden_test.ts) snapshots
paf_synth_schema.{hpp,ts} and verifies regeneration matches the
golden + that a second run is idempotent.
Until stream 1 lands nisps/core/math.hpp, schema_types.hpp ships
its own minimal Curve enum with a TODO marker pointing at the
eventual include.
