araharah-executor 020eb92058 feat(06-04): /api/route engine-A arm + http-source backend #2 — Bearer-gated, honest-null, RP re-pinned (GREEN)
- bot/src/routing/worker-router.ts: module-scope per-env graph memo (1 R2 GET per
  cold isolate, shared with the 06-07 cron arm via loadGraph), snap+A*+deriveSteps,
  claim-gated 401 / 4096-cap 413 / V5 bbox 400, 200-null on every miss class,
  ONE best route (no alternatives), category-only logs
- webhook.ts: /api/route arm delegating to handleRoute (405 non-POST)
- config.ts: ROAD_GRAPH: R2Bucket — first R2 binding (never a KV namespace, GE5)
- wrangler.jsonc: r2_buckets ROAD_GRAPH -> araharah-graphs with the fork law comment
- routing/src/http-source.ts: createHttpRoutingSource — slug-guard-first, fail-honest
  (throw/non-200/malformed/null-body -> null), defensive RouteResult validation;
  exported from index.ts; ladder note: backend #2 LIVE
- A7 re-pinned (06-01 named 06-04 as the owner of createHttpRoutingSource)
- test-side fix during GREEN: the R2 fake hands decodeGraph an exact ArrayBuffer
  (Node Buffers are views; encodeGraph output is already an ArrayBuffer)
- bot 103 passed / routing 65 passed; both typechecks clean

araharah-executor e34c2296f5 feat(06-01): typed-array A* + turn classifier + step derivation + public exports (GREEN)
- routeAstar: allocation-free hot loop — binary heap of node indices over
  preallocated typed arrays (grown by doubling), typed-array g/closed/
  came-from, on-demand cached haversine/maxSpeed heuristic (admissible +
  consistent); oneway-reverse edges never relaxed; unreachable -> null
- A1 proves A* == brute-force Dijkstra on ALL 625 mini-graph pairs
- classifyTurn: the one turn authority (compass convention — negative
  delta = left; plan's (0,40)->slight-left case contradicted its own
  (0,-90)/(0,90) pins, documented deviation); TURN_* constants exported
  for plan 07's cron projection
- deriveSteps: splits at non-straight bearings or name changes; steps
  carry kind/name/distanceM + polyline6; depart-first, arrive-last
- index.ts: engine-A named exports + ladder note updated — backend #2 is
  now 'engine-a' (D-01 supersedes the wasm-router note; Valhalla port
  infeasible + geojson-path-finder rejected, engine B = post-v1
  evolution, D-02); createHttpRoutingSource deliberately absent (plan 04)

araharah-executor 6adfd86ade test(06-01): add failing A* equivalence + step-derivation suite A1-A8 (RED)
- A1: exhaustive 625-pair A*-vs-Dijkstra equivalence (the RESEARCH-mandated
  correctness gate); A2 oneway detour; A3 honest-null unreachable
- A4/A5 deriveSteps: L-path turn kinds + name/distance/polyline6; depart/
  arrive invariants; A6 classifyTurn pins (compass convention, documented)
- A7 index.ts public surface (createHttpRoutingSource deliberately absent);
  A8 no-Map structural gate
