package main

// Reference QR matrices, produced by the Python "qrcode" package - an
// implementation SnapBeam shares no code with - and pasted here verbatim, so
// that TestQRMatrixMatchesIndependentReference can compare SnapBeam's encoder
// module for module against a second opinion rather than against itself.
// '#' is a dark module.
//
// Each reference is generated with an EXPLICIT mask pattern. That is
// deliberate: python-qrcode chooses its mask by scoring a symbol whose format
// modules have been blanked out, while ISO/IEC 18004 section 8.8.2 scores the
// complete symbol, so the two implementations legitimately pick different
// masks for the same data. Fixing the mask compares everything else - the bit
// stream, the block split, the Reed-Solomon codewords, the interleaving, the
// zigzag placement, the format bits and the version bits - exactly. Mask
// selection is checked separately by TestQRMaskSelectionMinimisesThePenalty.
//
// Regenerate with the snippet below, which pins the mode as well as the mask:
//
//	python3 -c "import qrcode; from qrcode.util import QRData, MODE_8BIT_BYTE; \
//	  q=qrcode.QRCode(error_correction=qrcode.constants.ERROR_CORRECT_M, \
//	                  box_size=1,border=0,mask_pattern=6); \
//	  q.add_data(QRData(b'...', mode=MODE_8BIT_BYTE, check_data=False)); q.make(fit=True); \
//	  print('\n'.join(''.join('#' if c else '.' for c in r) for r in q.get_matrix()))"
//
// The explicit MODE_8BIT_BYTE matters: left to itself python-qrcode splits a
// URL into byte and alphanumeric segments, which is a perfectly valid but
// different encoding of the same string. SnapBeam only ever emits byte mode.

// version 1 at level L, one block, no alignment pattern.
// Payload 8 bytes in byte mode, mask 3, 21 modules square.
