- The stage between edge compaction and encode feeds the graph's edges to
landmark.ts (farthestPointAnchors + landmarkTables + landmarkCoverage) —
the script quantizes and implements nothing itself (single-authority law)
- D-02 scaling rule L = clamp(round(N/13000), 16, 32) (~24 at KL's 311k
nodes) with a --landmarks <n> measured knob (positive int, hard cap 128,
parsed before --check)
- Honest gates before any write: quantum-ceiling throw -> fail with the
raise-quantum hint (Pitfall 5); per-anchor coverage >= 0.9 (the SAME
fraction for any L — the override cannot lower it, T-08-11); anchor
shortfall fails loud instead of encoding a weaker ALT
- encodeGraph receives landmarks: { quantumS, nodes, to, from } — the one
ARG2 authority; no local fallback encode
- Stats gate prints L/quantum/coverage min-mean/table bytes/sentinel totals
BEFORE the size gates; --check mirrors the facts from the decoded binary
(landmarkCount/quantum/anchors/coverage/sentinels, no network)
- A1 ladder history gains rung (c2): EXECUTED in this preprocessing stage
- routing/scripts/build-glyphs.mjs: maintainer shell (Usage/Exit codes/
collect-then-write — a missing/invalid source exits 1 with the kind named
and nothing written); recolors currentColor → #EB8008 in-memory and
injects a full-bleed #1A1A1A plate (stroke="none" — it must not inherit
the root's orange stroke); the committed SVGs are THE single source and
stay untouched
- sharp 0.35.5 as a routing devDependency (maintainer-only, zero runtime
deps); 'glyphs' script added
- 8× 256×256 PNGs committed (web/public/glyphs/) — the chat turn-card's
sendPhoto URL rides the Worker's static handler; two render bugs fixed
en route: density multiplied the explicit size attrs into 2048² (dropped),
and the plate inherited the root stroke (orange frame — stroke="none")
- SVG sources verified unchanged after the run
- upload-road-graph.mjs: wrangler-shelled maintainer tool (pre-flight 1-80MB,
round-trip verify hint); bucket araharah-graphs NOT created — R2 is not yet
enabled on the account (wrangler code 10042) — dashboard one-time activation
is the phase's user_setup item
- measure-route-cpu.mjs: 25-pair gate (corpus + seeded quadrant spread),
hrtime around routeAstar, warm-up excluded, unreachable probes reported
SEPARATELY from the routed p95, exits 1 over the 8ms budget
- Rule 1 (measured): the class set lacked *_link ramps — the graph FRAGMENTED
(7.7% of nodes in severed motorway islands; corpus pairs 'unreachable').
5 link classes added -> 311325 nodes / 677068 edges / 14.7 MB, all landmarks
in one component; enforced floor corrected 1KB -> 1MB (D-01)
- ladder (a) drop tertiary+residential: p95 17.8ms but 12/25 pairs unreachable
— REJECTED on correctness (D-03), reverted, ladder history recorded
- ladder (b) bidirectional A* (BH, Ikeda potentials, reverse-CSR WeakMap):
provably optimal (A1 625-pair sweep green), alternation balanced by heap
size (raw-top comparison starves the backward side 19501:3), reduction
signs in the standard feasible form. Measured: p95 ~38-93ms — NO GATE PASS.
The potential split halves each side's steering, cancelling the halved radius
- GATE FAIL is the honest verdict: ladder (c) — Workers Paid vs layout-v2 ALT
(still $0) vs free-plan-with-degradation — requires maintainer sign-off;
docs/ROAD-GRAPH.md carries the decision table and the fork contract
