Subject: [PATCH] test(06-02): add failing D-16 drive replay suite R1-R12 +
 four committed drive fixtures (RED)

  storm guard, shortened grace, haptic edges, start gate, projection
- fixtures derived from golden pair central-market-to-merdeka-118
  (ODbL attribution in each _notice; Fix-shaped streams per D-16)

+ * guidance-replay.test.mjs — GUID-02/GUID-06: THE D-04 reroute state machine,
+ * replay-proven (D-16) + the D-15 distance throttle.
+ * ---------------------------------------------------------------------------
+ * The four committed drive fixtures (web/test/fixtures/drives/*.json) are
+ * Fix-shaped JSON streams derived from the committed golden pair
+ * central-market-to-merdeka-118 (public ODbL data; attribution travels in
+ * each file's _notice). Each drive is folded fix-by-fix through the pure
+ * reducer (createGuidanceSession + stepGuidance) — no DOM, no maplibre, no
+ * device, no network — and every D-04 transition, the storm guard, the
+ * missed-turn shortened grace, the haptic edge stream, and arrival are
+ * asserted on the recorded frames.
+ *
+ * Cases:
+ *   R1  named constants pinned (the D-04/D-07/D-08/D-14/D-15 table)
+ *   R2  corridor-follow: start gate, on_route throughout, zero reroutes,
+ *       haptic approach/maneuver edges, arrival (D-16 corridor)
+ *   R3  off-route excursion: exactly ONE reroute-requested; storm guard
+ *       holds under an immediate second excursion (RESEARCH Pitfall 6)
+ *   R4  missed-turn excursion: shortened grace — the request fires well
+ *       inside OFF_ROUTE_GRACE_MS
+ *   R5  GPS jitter: never leaves on_route, zero reroute effects
+ *   R6  guidance start gate (GUIDANCE_START_ALONG_M; PX-03 binds in plan 05)
+ *   R7  reroute-failed -> honest no_reroute, then self-heal to on_route
+ *   R8  self-heal: off_route -> resuming -> on_route without a reroute
+ *   R9  storm-guard mechanics: a second request only after STORM_GUARD_MS
+ *   R10 projectAlongRoute: forward-only projection, cumulative remaining
+ *   R11 accuracy-aware threshold: max(35, 2xaccuracy) capped 100
+ *   R12 structural: the module is pure (no console/document/maplibre/
+ *       localStorage) and haversineM is THE distance authority
+ *   T1..T3 (task 3) the D-15 distance throttle + watchPosition wrapper
