Default stub_length increased from 2.54mm to 7.62mm (3 grid units)
so labels clear component bodies. Per-connection stub_length and
direction overrides added for edge cases where auto-placement puts
labels in bad spots.
Classifies unconnected nets into optimal wiring methods (direct wire,
local/global label, power symbol, no-connect) based on pin distance,
crossing count, fanout, and net name patterns. Delegates all file
manipulation to apply_batch, inheriting collision detection and label
serialization for free.
Strategy concepts informed by KICAD-autowire (MIT, arashmparsa).
New modules:
- patterns/ library: decoupling bank, pull resistor, crystal oscillator
placement with power symbol attachment and grid math helpers
- tools/batch.py: atomic file-based batch operations with dry_run
- tools/power_symbols.py: add_power_symbol with auto #PWR refs
- tools/schematic_patterns.py: MCP wrappers for pattern library
- tools/schematic_edit.py: modify/remove components, title blocks, annotations
- resources/schematic.py: schematic data resources
43 new tests (99 total), lint clean.
