CoreLibrary v1 Target List (reconstructed 2026-07-07)

The original master spec (Corelibrary expansion plan.md §7.4) was lost. This list is reconstructed from the existing 125-component inventory (gap analysis) + TODO.md Wave-2/deferred + jellybean conventions, verified against the vendored KiCad 10.0.4 clone (../references/kicad-libs). Goal this round: KiCad-vendored parts only → ~180–210 components (external Wave C parked).

Per-wave ritual (unchanged): branch feat/corelib-<phase> → author tools/manifests/<phase>.json → sparse-checkout the wave's .3dshapes dirs (git -C ../references/kicad-libs/kicad-packages3D sparse-checkout add <Lib>.3dshapes) → import-kicad-batch --strict → validate --release --strict → audit:3d (0 err) → bun test → pack --version=0.0.0-dev → merge. Every footprint MUST resolve a STEP under kicad-packages3D/<Lib>.3dshapes/ — verify before adding; any part lacking an upstream STEP drops to Wave C. Prefer all-new asset ids over --allow-overwrite.

Clone corrections to TODO.md Wave-2 (older/incomplete checkout): PC817 (Isolator), screw terminals (TerminalBlock_*.pretty), MountingHole (symbol+fp) ARE present in KiCad 10.0.4 → moved out of "external". Re-verify STEP per footprint.

Wave A — highest-demand jellybeans, KiCad-symbol-verified (~30)

All symbols confirmed in the clone. Footprint families all present; STEP-verify each before import.

Wave C — PARKED (external-sourced; not this round)

Absent from vendored KiCad 10 OR needs non-KiCad assets / special 3D handling: MPU-6050 (no STEP), HC-SR04 (no dedicated symbol), DHT11/DHT22 (body-below-board rotation; DHT22 no symbol), ESP-12F (only ESP-12E fp), microSD (Connector_Card absent), USB-C (complex pinMap), 74HC125 (only LS/LVC/AHCT), MP1584/MP2307 (no symbol), EC11 encoder, buzzer (TDK STEP bakes 15mm below board), relay, JST-XH 3D (no STEP). Revisit to close ~200 → 250–300.

Cross-cutting cleanups (opportunistic, low-risk)

  • Category fix: ic.ams1117-3v3 → belongs in power/ (all other AMS1117/LDOs are there). Needs aliases[] for id remap (app migrateLegacyAliases handles it).
  • Subcategory normalization: unify opamp/op-amp/amplifier/audio-amp and regulator_linear/regulator-linear-ldo to a single convention.
