amosblomqvist 0a4a9a11de BYOK provider embeddings (wave 6 chunk B): kill local transformers
Replace the @huggingface/transformers local embedder (~316MB ONNX cache)
with an EmbeddingPort seam: graph.embeddingModel (nullable "provider:id"
slug) selects an OpenRouter/OpenAI/Gemini adapter, resolved fresh per
call from settings + the auth store so key rotations land immediately.

- src/server/embeddings.ts rewritten: slug grammar, injected-fetch
  adapters (OpenRouter input_type, Gemini taskType batching, OpenAI
  index-ordered rows), honest resolution (null = skip-with-info, set
  model with missing key = honest error), embedNewNodes with model-change
  re-embed wipe + ghost pruning + usage steps, federated catalog
  (OpenRouter /api/v1/embeddings/models — VERIFIED live, the inverse
  path 404s; OpenAI text-embedding- filter; Gemini embedContent filter).
- GET /api/models/embeddings: federated catalog, empty when no keys.
- Extraction tail records stages.embedding usage into the run's money
  channel; EMBEDDING_PRICES overlay in core/prices.ts (outside the
  sync-generated block), callCost falls back to it; cost-summary folds
  the fourth stage; graph-context injection resolves its embedder per
  run, fails honestly when unconfigured, records query tokens.
- Settings: GraphSettings.embeddingModel (null factory), section parser
  validates slug shape (id may contain colons — OpenRouter :free
  suffixes, live catalog fact).
- Removal: @huggingface/transformers uninstalled, PATHS.modelCache and
  onnx tracing entries deleted, @huggingface tracing-excludes guard
  added, stale sharp/libvips comments updated to historical.

Live-verified on port 3004: catalog federates 36 rows (33 OpenRouter +
3 OpenAI), embedNewNodes embedded 10 nodes via the free liquid/lfm-2.5
model (dim 1024, 435 prompt tokens, 1 call, $0), settings PUT rejects
bad slugs with 400.

Gates: typecheck, lint, 895/895 tests, build.

amosblomqvist 7902984bd6 feat: Electron desktop wrapper — LearnHarness.app (macOS arm64)
The web app becomes a desktop app without changing shape: the Electron
shell spawns the Next standalone server on a loopback port and points a
sandboxed window at it. All app logic stays in the Next server.

Bands:

1. LH_DATA_DIR seam (config.ts): PATHS.data/chats/graph derive from
   process.env.LH_DATA_DIR (else repo data/, unchanged in dev). New
   PATHS.modelCache routes the transformers.js embedding-model cache
   (~300MB) to <data>/models when the seam is set — the default cache
   inside node_modules is read-only in a packaged bundle. All existing
   fs writes flow through PATHS; teacherPrompt stays ROOT-anchored
   (read-only asset, ships inside the bundle by design).
   tests/data-dir-seam.test.ts covers set/unset via child process.

2. Standalone build (next.config.ts + scripts/build-server.mjs):
   output 'standalone'; outputFileTracingExcludes data/**/* keeps the
   repo's real session data out of the bundle (verified: an unexcluded
   scratch build traced 34 files / 716K of real chats + ledgers).
   Two empirically-verified tracer gaps required outputFileTracingIncludes:
   pi-ai's provider catalog (JSON import attributes — 39 files, 500s on
   /api/models without them) and onnxruntime-node's sibling dylib
   (libonnxruntime.dlopen via @rpath). build-server.mjs copies public/
   and .next/static per docs, refuses a leaked data/ dir, and asserts
   the runtime-read prompt .md assets are traced.

3. Electron shell (electron/main.cjs, no preload):
   - single-instance lock (two instances would fight over the data dir);
   - free port via listen(0); spawn via process.execPath +
     ELECTRON_RUN_AS_NODE=1 with PORT/HOSTNAME=127.0.0.1/LH_DATA_DIR;
   - BYOK: userData/auth.json, flat {VAR: value} JSON, mode 0600,
     merged into the child env only when absent from the real env
     (auth UI is the settings milestone; file is hand-editable);
   - poll until the server answers (no ready event), then open a
     contextIsolation+sandbox window; deny-by-default permission
     handler (media allowed only from the loopback origin — mic/STT
     groundwork); will-navigate pinned to origin, window.open denied
     with external links to the system browser; macOS Edit-menu roles;
   - quit path SIGTERM→3s→SIGKILL + exit/SIGHUP nets; child stdout
     mirrored to userData/logs/main.log;
   - dev mode via LH_DEV_URL: no spawn, points at next dev (HMR).

4. Packaging (electron-builder.yml + build/entitlements.mac.plist):
   files = electron shell only; the whole .next payload ships via
   extraResources from .next (filter standalone/**/*) — NOT from
   .next/standalone directly: electron-builder hard-excludes a copy's
   root node_modules and the default pattern is a literal match, so
   node_modules/ and .next/ were silently dropped and the server died
   with 'Cannot find module next'. Asar holds no native code.
   Unsigned (identity: null) until a Developer ID cert exists; hardened
   runtime + audio-input entitlements laid now for the STT milestone.
   desktop:dev / desktop:dist scripts (electron 44, electron-builder 26).

Live smoke of the packaged .app: server up on a random loopback port,
all API routes 200, a real GLM chat turn answered end-to-end via
auth.json BYOK, chat persisted under userData/data, second instance
exited via the lock, no orphaned server child after quit.

Gates: typecheck, eslint, 500/500 tests (+2 data-dir-seam), build.
