Altium ASCII Schematic Corpus Fixtures
======================================

All files in this directory are synthetic fixtures authored for ZapTrace CI
testing. They follow the Altium Designer ASCII schematic export format
(pipe-delimited records with |RECORD=N| type fields) as documented in the
Altium Designer PCB API reference.

No proprietary Altium schematic data has been used. All content is:

Files
-----
opamp_circuit.asc
  A simple inverting op-amp circuit with power pins, two resistors, one
  op-amp, and 4 labelled nets. Tests RECORD=28 (Component), RECORD=2 (Pin),
  RECORD=37 (Wire), RECORD=4 (Label).

mcu_breakout.asc
  A microcontroller breakout with decoupling capacitors, GPIO labels, and
  port connectors. Tests hierarchical port (RECORD=209) handling and
  multi-sheet-style labels.

adversarial_unsupported.asc
  Contains supported records plus several unknown record types (RECORD=99,
  RECORD=150, RECORD=200). Verifies that unsupported-record evidence is
  populated correctly and does not crash the importer.
