Five rounds, each looking from an angle the previous one cannot:
1. text — every "Thay đổi" bullet on the page vs a probe (existing)
2. geometry — check_layout_geometry.py: reading order of the rail, section
order down Monitoring, which side each pane is on, and the size
relationships the design names (hero card, 26px dot)
3. inventory— check_controls_alive.py: every control in controls.json still
present in the built app, attributed to its owning CLASS via the
baseline commit (a file holds several classes, so a per-file
check reported eight dialog controls as missing)
4. eyes — rendered screens read against the wireframes
5. adversarial — check_probes_bite.py: break one feature at a time and fail if
the matching check still passes
What rounds 4 and 5 caught, which 1-3 could not:
* Schedule showed six of seven lanes; the seventh needed a horizontal
scroll. The design says "giữ đủ 7 lane, thu hẹp cho vừa một màn". Lane
minimum width 190 → 150, so 7 × 150 + gaps fits a 1280 window. Round 2 now
measures this instead of relying on someone noticing.
* check_design_parity ALWAYS returned 0. It was a report, not a check: every
probe in it was incapable of failing, so a regression would print on screen
and still exit green. It now exits non-zero when anything is CHUA — which
is what let round 5 detect the two mutations it had been sleeping through.
Also fixed in the harness itself: it rewrote line endings while restoring
mutated files (read_text/write_text translate both ways), and it compared the
tree against "clean" rather than against its own starting state.
All ten checkers green by exit code.
