- 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
- cari.ts: /cari + /search twin, 128-char pre-search cap (T-04-21), honest
no-match refusal (D-13), single sendVenue card with inline OPEN + alternates
- deep-link carrier corrected per RESEARCH Pitfall 1: web_app button URL
carries ?dest=<plain slug id> — WebAppInfo has only a url field; no crypto
- origin from configured MINI_APP_URL only (never user input); blank origin
omits the OPEN button instead of guessing (T-04-30)
- strings.ts: searchUsage/searchNoMatch/searchQueryTooLong/searchOpenButton/
osmAttribution in en+ms; helpMenu gains the /cari line in both locales
- category-only logging law (D-15): four literal rejection categories, query
never logged; success path logs nothing
- config: MINI_APP_URL in Env + wrangler vars (public, not secret) +
.dev.vars.example + docs/CONFIGURATION.md row and sections
- bot deps gain @araharah/search (workspace link)
- docs/SEARCH-QUALITY.md: the bake-off close record — corpus v1 (75 cases) x
gazetteer v1 (30 entries), measured 2026-10-23T17:02Z via npm run search:corpus
- top-1 66/68 (97.1%), top-3 68/68 (100.0%) >= 90% threshold
- negatives refused 7/7, refusal margin 0.643 < 0.72 admission line
- per-category table (landmark/abbreviation/glued/typo/alias all 100%)
- escalation lever: None — met on first run; no abbreviations.ts row, no
alias, no corpus edit; the fixed ladder was never climbed
- coordinate verification: 10 seed entries spot-checked against Nominatim
(identifying UA, 1 req/s): 8/10 within 0.01°; bukit-bintang outlier is an
area-vs-point discrepancy (no change); pavilion-kl was a real ~2 km error
- both top-1 misses documented as expected disjoint-tier behaviour
- kl-gazetteer.json: pavilion-kl coordinate corrected (3.1478,101.695) ->
(3.149,101.7132) — Rule 1 data bug found by the prescribed Nominatim
verification; post-fix delta 0.0002°; corpus is coordinate-blind, all suites green
