- 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
- standard encoded-polyline algorithm at 1e6 precision, double math
(no int32 shifts) so no coordinate range wraps silently
- decode THROWS on truncated varints — never partial/NaN points (T-05-02)
- round-trip law encode(decode(s)) === s proven on all vectors incl.
the external live-OSRM geometry (RESEARCH Finding 1)
- 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)
