refactor(server): extract /api/tunings into routers/tunings.py + lib/appconfig.py (R3) (#858)
The merged-tuning-catalog route moves to lib/routers/tunings.py, verbatim except
@app->@router, CONFIG_DIR->appstate.config_dir, and the two seam substrates it
needed:

  - lib/appconfig.py — the pure config.json reader `_load_config` (used by ~11
    server sites + future config-reading routers). server.py re-imports it, so
    those call sites and any `server._load_config` test reference are unchanged.
  - appstate.tuning_providers — the TuningProviderRegistry instance injected by
    reference (a stable object mutated in place via register()/unregister()), so
    the router reads the same registry plugins populate through plugin_context.
    The instance stays defined in server.py, so `server.tuning_providers` still
    resolves — zero test retargets.

The tuning constants (DEFAULT_REFERENCE_PITCH, TUNING_PRESET_MIDIS,
freqs_to_midis) already live in lib/tunings.py and are imported directly.

server.py: 6,960 -> 6,917.

Verified: pyflakes clean (bar the pre-existing unused `tuning_name` import);
route table IDENTICAL (143); full pytest 2400 passed (110 tuning/config cases);
eslint 0. Boot smoke: /api/tunings serves referencePitch + tunings + tuningMidis.

Size-exemption register

The working norm (constitution Principle II; enforced by the max-lines lint gate) is no source file over 1,500 lines. A few files are allowed to exceed it because splitting them would do more harm than good — hot per-frame renderers, C++, offline generators, cohesive registries. This register is the list of those exceptions: each row is a deliberate, signed decision with a ceiling, a rationale, and a review trigger. Without it, "no file over 1,500 without a signed exemption" is unenforceable.

Rules

  • One row per file: a ceiling, a rationale, a signer, a review trigger.
  • The max-lines per-file ceilings in eslint.config.js mirror this table — keep them in sync (this register is canonical).
  • Files with a scheduled split plan are not exempt — they live in "Planned, not exempt" at the bottom so nothing falls between the two states.
  • Signers (decided 2026-07-08): Byron signs core + bundled rows; Christian signs the authored-plugin row (virtuoso, its own repo/track).

Permanent exemptions (structural rationale)

Repo / file Lines (7-07) Ceiling Rationale Signer Review
core static/highway.js → residual renderer-2d.js (post-split) ~2,4002,900 est. 3,000 60 fps hot path; no module boundary inside the per-frame loop Byron after the highway.js split
core plugins/highway_3d/ → residual renderer sized at split; likely >3,000 set at split, flagged now same hot-path rule; the draw core can't be cut without behavior risk Byron after the highway_3d split
core static/capabilities.js 1,538 1,600 cohesive registry + window.feedBack bus, 38 lines over; a split spends credibility for nothing Byron R4
tutorials builtin/reading-the-highway/generate.py 1,818 2,000 offline content generator, never imported at runtime, deps not in runtime requirements Byron if a 3rd builtin pack appears
desktop src/audio/NodeAddon.cpp 3,542 as-is C++, outside the ESM/routes playbooks; under active use-after-free crash work — do not churn Byron after crash-class work settles
desktop src/audio/AudioEngine.cpp 2,977 as-is same Byron same
desktop src/vst-host/main.cpp 1,928 as-is same Byron same
virtuoso screen.js (authored, own track) 25,741 as-is until its own split authored plugin on a separate roadmap; migrates on its own schedule Christian virtuoso split kickoff

Split-when-touched (no scheduled train; row retires when split)

Repo / file Lines Ceiling Rationale Signer Review
core lib/gp2rs_gpx.py 2,540 as-is import converter, off the serve-path hot loop Byron when next touched
core lib/gp2rs.py 2,055 as-is same Byron when next touched
core lib/song.py 1,689 as-is data models + wire format; cohesive Byron when next touched
core lib/gp_autosync.py 1,572 as-is under active dev (#787/#791) — don't collide Byron after in-flight work lands
core plugins/capability_inspector/screen.js 1,752 as-is bundled diagnostics plugin, low churn Byron when next touched
core plugins/folder_library/screen.js 1,672 as-is bundled plugin, low churn Byron when next touched

Temporary rows (cleared by a scheduled PR)

Repo / file Lines Cleared by
core plugins/__init__.py ~2,470 (grew under R0) the plugins/_routes.py + plugins/_registry.py split (rides the server.py router work)

Watch list (under the norm — no row needed, re-census each phase)

musicxml-import/mxml2notation.py (1,456) · core static/capabilities/audio-effects.js (1,436) · studio routes.py (1,399) · update-manager screen.js (1,492 — zero headroom).

Planned, NOT exempt (owned by split plans — listed so nothing falls between states)

core static/app.js (11,852) · static/highway.js (4,168, whole file) · server.py (6,917 — was 14,037; ratcheted by the R3 MetadataDB + AudioEffectsMappingDB extractions and fifteen routers/ modules) · lib/metadata_db.py (4,373 — new in R3; the MetadataDB class alone is 4,018 lines and is a monolith in its own right, to be split per-table once the router train lands) · static/v3/songs.js (4,134) · static/capabilities/audio-session.js (2,974) · plugins/highway_3d/screen.js (15,656) · plugins/keys_highway_3d/screen.js (3,780) · plugins/drum_highway_3d/screen.js (3,597) — and every monolith with a PR train in the refactor plan. Test files (e.g. tests/test_plugins.py) are out of scope by policy — the norm governs source files.
