Adds two foundational pieces shared by every concrete mode:
- `base.hpp`: defines `nisps::ParamSchema` (the aggregate type the
`Mode` concept's `param_schema()` returns by const-reference),
`nisps::ControlEvent`, and `ModeBase<Derived, EngineT, MLPType,
NInputs>` — a CRTP scaffold absorbing input forwarding, ML
inference + voice space mapping, engine.set_params() routing, and
a per-mode ControlEvent ring buffer for MIDI/I2C events.
`ModeRoutesOutputsToEngine<Derived>` lets a derived mode (e.g.
SoundAnalysisMIDI) opt out of routing ML outputs to engine
params when its outputs become MIDI CCs instead.
- `voice_space.hpp`: `VoiceSpaceEntry` + `make_voice_space_entries()`
+ `find_voice_space()` helpers. Voice-space *mapping code* lives
inside engines (mirroring firmware); mode layer just selects
which voice space the engine uses by index/name.
No heap, no virtuals, no Pico/Arduino dependencies; satisfies stream
4 of architecture.md.
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.
Output of \`bun run codegen/generate.ts\` for the 8 mode schemas.
These files are checked in so consumers don't need bun on every
build, but they remain regenerable and byte-identical.
C++ (nisps/modes/generated/):
schema_types.hpp + 8 <mode_id>_schema.hpp files. All compile
cleanly with g++ -std=c++20 -Wall -Wextra -fsyntax-only -I nisps.
TS (playground/src/modes/generated/):
types.ts + index.ts + 8 <mode_id>_schema.ts files. Type-check
cleanly with tsc --strict.
