- 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).
farthestPointAnchors + landmarkTables + landmarkCoverage over the
ĉ metric: edge weights floor-quantized once (Math.floor(seconds/q)),
exact integer Dijkstras (Int32 labels, binary heap, lazy deletion),
0xFFFF sentinel, 65000-quantum loud overflow. Traversal law mirrors
astar.ts verbatim: bit0 edges never relaxed in EITHER direction.
Test-vector corrections caught at GREEN (expectations were wrong,
implementation was right):
- L4: rows index by anchor POSITION (row-major [l*N+v]), not node id
- L6: the c-metric farthest node from corner 0 is interior node 18
(297q: interior hops cost 2x perimeter), not corner 24 (264q) —
verified against an independent brute-force Dijkstra
A 2-node graph has no degree>=2 candidates, so farthestPointAnchors
returns empty before any Dijkstra runs and never reaches the overflow
throw. Node 1 on a 3-node path is a candidate, so the selection pass
actually exercises the law.
Hand-computed vectors for the pure landmark compute core: deterministic
degree-filtered farthest-point anchors, exact integer quanta
(floor(2.55/0.1)=25, two edges=50), 0xFFFF sentinel + self-cell laws,
oneway asymmetry, the 65000-quantum overflow throw, and the 5x5-grid
corner-to-corner 264-quanta vector with coverage 1.0.
- 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
- snapToGraph: bbox+margin guard first (honest null = router-pending,
D-03), then 3x3 coarse-grid neighborhood (0.002 deg cells, WeakMap
memo per RoadGraph — LAW 1 lazy memoize, O(local) not O(n))
- projection in cos(lat)-scaled degree space (Pitfall 8); returned
distance is haversineM; result carries the best segment's nameId
(null for the unnamed sentinel) for plan 07's cron street-hop
- oneway-reverse edges stay snap-visible (direction is A*'s law);
gridBuildCount() instrumentation kept internal to the workspace
- Pinned-layout gates: round-trip, bad magic/version/truncated -> null,
zero-copy view mutation, name pool, committed mini-graph fixture pin
- Each case lazy-imports ../src/graph.ts — ERR_MODULE_NOT_FOUND is the
red state (fixture-source.test.mjs pattern)
- one test per check, mirroring search/test/corpus.test.mjs: the suite imports
measurePairs from routing/scripts/route-corpus.mjs IN-PROCESS (never spawns
the CLI) — one measurement, two reporters, no drift
- RED: the measurement core does not exist yet -> 10 named ERR_MODULE_NOT_FOUND
failures; the committed dataset itself is already green material (task 1)
- fully offline by construction: zero network in the measurement path (T-05-05)
- L3 previously pinned the 05-01 empty-seed state (honest null at the pinned origin)
- it now asserts the default fixture source SERVES pair 1 (kl-tower-to-kl-sentral)
at its pinned public origin and resolves honest null ~300 m away (outside the
200 m tolerance, D-03)
- RED until plan 05-02 populates the committed fixture dataset
- synthetic injected datasets only — never the network, never the committed file
- F3 pins the 200 m haversine tolerance boundary; F6 the defensive pair skip
- F7 the lazy-index source gate (LAW 1); L2 the esbuild inline marker
- hand-derived vectors from the plan's <polyline_vectors> block
- external live-OSRM demo geometry (RESEARCH Finding 1) as ground truth
- P7 pins the truncated-varint refusal law (T-05-02)
