Adversarial-oracle fixtures (WP-G)

Seeded-defect pages for the verification oracle. The trap catalog (bait → required verdict) lives in README.md and in the exported CALIBRATION_SUITE constant — the two are kept in sync by the browser-gated calibration test.

Controls (must PASS)

• control-healthy.html — navigate / focus / hover / network all genuinely work
• healthy-target.html — the HTTP 200 navigation target

Traps (must never pass)

• trap-focus-mimic.html — success styling, focus never lands
• trap-console-swallow.html — silent throw, clean console, stale state
• trap-covered-control.html — visible + enabled but covered by an overlay
• trap-flaky-control.html — works on alternating page loads
• trap-redirect-escape.html — parse-time redirect off-origin

Broken pages (must FAIL with evidence)

• broken-404-link.html — link to a real 404
• broken-focus-never.html — focusable button that never keeps focus
