SM59 single-seat manual extraction (Opus). P8 pedal-batch tracer #3/13.

Manual-grounded extraction from manuals/fx-modulation--mxr-flanger-mini-manual.pdf. Front-panel controls captured per the manual's panel descriptions; field provenance is 'high' on what the manual directly states + '_verify' on what it does not. Schema extension fields used by this pedal (params.modulation block; params.distortion.mode_select; io.bypass_type from SM58) are documented in SCHEMA-capability-outboard-v1.md.
