monkey-w1n5t0n 68d4cc4017 build(firmware): migrate to PlatformIO and vendor memllib (plan §5)
One cut, no dual path. Closes ALIGNMENT defect 3 ("Arduino-CLI build
machinery is actively hostile") and vision bullet 4.

platformio.ini carries 16 [env:], one per variant, each passing
-DMEMLNAUT_MODE_TYPE; selftest passes -DNISPS_SELFTEST=1 instead. The env list
IS the registry now — the .ino comment-registry and the NISPS_ST_* token-paste
table are deleted rather than migrated. L12 noted that table was already
silently missing the currently-shipped SLPWorkshop variant, which is the whole
argument against having a second list.

Also deleted: the Python/sed machinery that rewrote the COMMITTED .ino on every
build, the sketch symlink forest, the global TFT_eSPI User_Setup.h mutation
(now -D flags — TFT_eSPI's own documented PlatformIO recipe), the UF2
boot-mount detection stack (upload_protocol=picotool talks to the bootloader
directly), and build-firmware-arch.sh entirely. Scripts 683 -> 435 lines.

memllib is vendored at lib/memllib/ from upstream e291192; no submodules
remain. VENDORED.md records provenance and the re-sync procedure.

S9: a firmware-build CI job compiles three representative envs against a cached
toolchain and reports per-variant flash/RAM. Firmware is in an automated gate
for the FIRST time. The old ci.yml comment justified excluding it as "low
verification value" — an assessment that did not survive contact, since the
SelfTest variant sat broken for an unknown period calling a DisplayDriver
method that did not exist at the pinned memllib commit, and nothing noticed
because nothing built it.

Verified: all 16 envs build from an empty cache, each within ~520 bytes of the
arduino-cli binary it replaces, flash and RAM. Measured as .text+.rodata /
.data+.bss+vector+uninitialized — NOT PlatformIO's console line, which
double-counts .data on this board. This does not prove the hardware boots; no
flash+smoke test was possible and that stays an operator chokepoint.

  slpworkshop 248232/145028   pafsynth 256880/149716   selftest 216228/17960
  (all 16 in the CI log format; none exceeds 2% of a 16 MB flash)

Two traps recorded so nobody rediscovers them: vendoring memllib's subdirs
without a src/ wrapper makes PlatformIO's library builder silently compile
NOTHING while still linking; and project build_flags land BEFORE the
framework's own -std=gnu++17 -Os, so build_unflags is required.

CORRECTION carried in this commit: the firmware sizes in c19d846's message and
the first version of the memllib recon doc were wrong — SLPWorkshop 145348,
PAFSynth 145300, SelfTest 141840. They came from building variants in sequence
through a SHARED incremental arduino-cli build directory, which reused stale
objects and under-reported by ~75 KB. Clean-cache rebuilds of the identical
commit give 216736/18492 for SelfTest. The real cost of the memllib upstream
bump is +216 bytes flash, not +316. Never measure firmware size through a
reused build dir.

HISTORY NOTE: this commit and the docs commit before it were rebuilt (force-push,
2026-07-21) so that each contains only what its message describes. The first
versions had the firmware deletions stranded in the docs commit by a shared-index
race between concurrent agents; content is byte-identical to the originals.

Gates: run-all-tests.sh ALL GREEN (nisps/ untouched by this change beyond
include paths); 16/16 pio envs build.

Neural Interactive Shaping of Parameter Spaces

Firmware

The hardware firmware targets the MEMLNaut RP2350 build and uses repo-local helper scripts for the known-good build configuration:

git submodule update --init --recursive

scripts/build-firmware.sh
scripts/flash-firmware.sh
scripts/build-and-flash-firmware.sh

Notes:

  • The scripts build for rp2040:rp2040:solderparty_rp2350_stamp_xl with Optimize3.
  • The build forces C++20 because the firmware uses std::span and concepts.
  • build-firmware.sh accepts an optional variant name such as MEMLCelium or BreakOr. Matching remains case-insensitive, so memlcelium still works. If you omit it in an interactive shell, the script parses MEMLNaut-NISPS.ino, prompts for a variant, and rewrites the active MEMLNAUT_MODE_TYPE before building.
  • flash-firmware.sh accepts an optional mountpoint argument, or auto-detects common UF2 bootloader mounts such as /run/media/$USER/RP2350 and /run/media/$USER/RPI-RP2.

Manifold (browser app)

Try NISPS in your browser — no hardware required. Manifold is the React front-end running the same C++ engines + ML as the firmware, compiled to WASM:

cd manifold
bun install
bun run dev

Staging deployment: https://meml.lnfinitemonkeys.org/next/

Train a neural network to map input gestures to synth parameters through interactive machine learning: place examples, or use verdict-based feedback (explore-and-place, geometric dislike).

(The former SolidJS playground was retired in July 2026 — archived on branch archive/playground-solidjs, tag playground-solidjs-final.)
