- graph.ts: ARG3 layout (magic 0x41524733, version 3, chShortcutCount u32 @60, reserved @64/@68) with the CH suffix chRank ++ shortcut CSR; fail-honest decode (ARG1/ARG2 -> null, chShortcutCount 0 -> null, exact-size before any allocation, 4-byte alignment load-bearing); loud ch-block encode validation - ch-query.ts: routeCH — bidirectional uphill search (strict rank filter, forward originals+shortcuts, backward reverse views incl. shortcuts), edge-ref meet probe, iterative via-unpacking (edge-aware: a parallel original edge is never expanded as a shortcut; DERIVE prefers the cheaper of original/shortcut), seconds re-summed from the unpacked original-edge path. STOP RULE: min(topF, topB) >= mu — the classical sum rule is unsound under the rank filter (Q1 caught it: 36 vs 24) - astar.ts: routeAstar validates + delegates every request to routeCH; ALT/BH internals, clean-column memo, landmark tokens DELETED (D-04); classifyTurn/deriveSteps untouched - landmark.ts + landmark.test.mjs deleted (D-05); index.ts additively exports contractGraph + CH constants + routeCH - snap.test.mjs: S3's encode moved to the ARG3 ch block (3-node star — a 2-node graph can carry no valid shortcut); committed-fixture S-cases suspended until task 3 (Rule 3: same pattern as G7/A1-A6) - routing suite: 86 passed, 0 failed; typecheck clean

/*
|
||
* snap.test.mjs — GPS-fix snapping gates (S1–S6).
|
||
* ------------------------------------------------
|
||
* RED first (plan 06-01 task 2): every case fails while
|
||
* routing/src/snap.ts does not exist (lazy-import pattern).
|
||
*
|
||
* D-05: the ROUTER snaps raw fixes to the graph (engine A owns snapping —
|
||
* one authority). The mini-graph fixture (mini-graph.bin) is the shared
|
||
* ground truth; a synthetic unnamed-edge graph covers the null-nameId half.
|
||
*
|
||
* S1 exact-node hit — a fix at a node's coordinates -> that node,
|
||
* distanceM ~ 0
|
||
* S2 mid-edge projection — a fix partway along a segment snaps to the
|
||
* CLOSER ENDPOINT (never a fabricated mid-node);
|
||
* distanceM is the haversine distance to it
|
||
* S3 nameId — the best segment's edgeNameId resolves;
|
||
* an unnamed segment resolves null
|
||
* S4 bbox margin — outside bbox + SNAP_BBOX_MARGIN_DEG -> null
|
||
* (honest miss, D-03); just outside the bbox
|
||
* but near roads still snaps
|
||
* S5 oneway ignored — a fix near the oneway segment still snaps to
|
||
* its endpoints (snapping ignores direction)
|
||
* S6 memoized grid — the coarse grid builds ONCE per RoadGraph
|
||
* (WeakMap; build-counter, kept loose) +
|
||
* structural: WeakMap and cos() in the source
|
||
*
|
||
* Phase 08.1 re-pin: S1/S2/S3/S4/S5/S6 read the committed mini-graph.bin (S3's
|
||
* perimeter half) — they are
|
||
* which is still ARG2 mid-plan — they are SUSPENDED until task 3
|
||
* regenerates the fixture through the ARG3 encode path (the same
|
||
* suspension pattern as graph.test.mjs G7 and astar.test.mjs A1–A6).
|
||
* S3 was re-pinned NOW: its synthetic graph moved to the ARG3 ch block
|
||
* (a 3-node star — a 2-node graph can carry no valid shortcut).
|
||
*
|
||
* Run: npm run routing:test (exit 0 = all green)
