feat(06-01): CSR graph codec + committed mini-graph fixture + RouteStep.kind (GREEN)
- graph.ts: decodeGraph/encodeGraph over the pinned little-endian CSR
layout; header magic+version+exact byte-size validation BEFORE any view
allocation (T-06-03/T-06-03b fail-honest null); zero-copy typed-array
views; street-name pool with UNNAMED_NAME_ID sentinel
- header padded 60 -> 64 bytes so f64 views are 8-byte aligned — unaligned
Float64Array throws RangeError, making plan-literal offsets incompatible
with the plan's own zero-copy law (documented deviation; field
order/content/endian unchanged; consumers inherit via encodeGraph)
- build-mini-graph.mjs + committed mini-graph.bin: hand-built 5x5 grid,
25 nodes, 80 directed edges, 3 named streets, exactly ONE oneway pair,
two speed classes (60/30 km/h) — the A* ground truth (G7 pins it)
- types.ts: RouteStep gains optional kind (8 turn kinds) — Engine A
populates it (06-01); fixture-world steps stay empty arrays (D-10)

feat(05-02): pinned golden-pair corpus + OSRM-demo fetch tool + populated committed dataset (GREEN)
- routing/test/fixtures/golden-pairs.json: the hand-authored 15-pair pinned
corpus (D-02/D-12) — origins AND destinations are gazetteer landmarks,
klBbox + 100 KB gz budget + probe id + alternatives floor pinned
- routing/scripts/fetch-route-fixtures.mjs: the maintainer build tool
(overpass-topup.mjs pattern) — D-12 boundary in the header, pre-flight
public-coordinate proof against the gazetteer (1e-4 deg), mandatory
User-Agent, 1200 ms inter-request delay, one retry on network/5xx,
collect-then-write, --only=<pairId> single-pair repair merge
- routing/src/data/route-fixtures.json: 15 real OSRM-demo pairs committed
(1-3 verbatim polyline6 routes each; 8 pairs carry >= 2 alternates),
ODbL header fields preserved (T-05-06)
- loader-env L3 armed (RED commit 01b0ed6) + C6 re-pinned from the empty-seed
state to the populated corpus (05-01 documented both as 05-02 handoffs)
- npm delegates: root routing:fixtures; routing fixtures + corpus scripts
