Phase 1 group 8 (S8, ST2, L14).
- S8: the vendored src/daisysp tree (96 files, 41 .cpp compiled into every
firmware build) and its sketch-tree symlink. Zero consumers — nisps replaced
daisysp's PitchShifter with a custom granular implementation. Corrected
firmware/README.md and setup-firmware-toolchain.sh, which called it a live
submodule. The attribution comment in nisps/dsp/pitch_shift.hpp stays: it is
an honest provenance note about a port, not a dependency.
Noted while verifying: src/memllib/examples/KassiaAudioApp includes
../../daisysp/..., but examples/ is not symlinked into the sketch tree and is
never compiled by the firmware build, so the deletion stands.
- ST2: input_router.hpp was a zero-logic speculative layer with one consumer;
the .ino now calls bind_peripherals directly.
- L14: peripherals.hpp — deleted kAnalogInputCount, PeripheralBindings and the
unused spread local, and extracted the duplicated commit-and-train block into
one helper. The audit's suggested commit_and_train(mode, feedback) signature
could NOT be behaviour-identical: repositioning() implies placing() (both
live in ExploreState::Placing), so dispatching on feedback state inside the
helper would silently reroute a TogB2 press mid-reposition from commit_place
to commit_reposition, which differs (no snapshot restore, clears
reposition_). Implemented as commit_and_train(mode, feedback, bool
reposition) with the branch decided at the call site, preserving behaviour.
Firmware is not compiled by any gate yet (that arrives with the PlatformIO
migration, plan §5/S9), so this group is verified by reading and grep only.
Gates: run-all-tests.sh ALL GREEN.
