- FAILURE_VECTORS as data: 7 classes (empty/error/no-geometry/off-road/
location-timeout/old-client/route-timeout), each with trigger + expected surface
- FM2 drives the REAL buildRoutePendingCard (text, no undefined, CTA wired)
- FM3 rejecting + never-settling sources both stay off the draw path (200ms guard)
- FM4 RED: a <2-point geometry currently reaches the draw path — the pending
card must replace the half-drawn line (T-07-12)
- FM5 pure-reducer excursion: one reroute-requested, storm guard holds, CALM slot
- FM6 old-client chrome builds with zero capability calls (07-01 owns fullscreen)
- FM7 location chain lands designed denied/awaiting-pin states
