- A9: two-component synthetic (3x3 grid + 4-node path), anchors HAND-PINNED
inside component A only via landmarkTables; full 169-pair sweep asserts
seconds-only Dijkstra equivalence (A-internal with ALT live, B-internal
on the haversine fallback, 72 cross pairs -> null)
- A10: origin AND goal inside the anchorless component — all families drop
at SEARCH scope, the 16 B-internal pairs still route Dijkstra-equal
- A11: comment-stripped astar.ts must reference landmarkTo/landmarkFrom/
landmarkQuantumS in CODE; one sentinel spelling (0xffff, never 65535);
A8's no-Map law unchanged — FAILS now (RED: the potential is still
pure haversine)
- case-index doc-comment extended A1-A8 -> A1-A11; buildIslandFixture
helper routes fixture tables through the ONE landmark module
graph.ts versioned IN PLACE (no second codec): GRAPH_MAGIC 0x41524732,
GRAPH_VERSION 2, HEADER_SIZE 72 (72%8==0 keeps f64 views aligned);
header gains landmarkCount u32 @60 (the old pad), landmarkQuantumS f32
@64, reserved u32 @68; the landmark suffix (u16 toTable, u16 fromTable,
u32 landmarkNodes) extends layoutFor's total arithmetic — exact-size
law covers the variable suffix BEFORE any view allocation (T-08-01).
D-01 fail-honest: ARG1 bytes / version!=2 / landmarkCount=0 / hostile
quantum / size mismatch all decode null (committed mini-graph-arg1.bin
is the standing rejection vector). GraphInput.landmarks REQUIRED and
loud-validated (T-08-04). RoadGraph gains the five landmark fields
(Plan 08-03's ALT potentials consume them).
Fixture regenerated as ARG2 through the SAME encode authority: the
builder gains the tiny real landmark stage (L=2, anchors [0,18],
quantum 0.1s, coverage 1.0 — identical bytes every re-run).
Rule-3 call-site updates forced by the required-landmarks law (missed
by the plan's files list): astar.test A3 + snap.test S3 synthetics
carry inert hand landmark blocks. Fixture regen pulled forward from
task 3 so this commit's own battery is green (74 passed, 0 failed).
- 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
