They choose the one with the cash machine. No map holds that. We do â for 88,251 places, with a visible reason for every fact.
Same brand, same logo, same Wikidata id, 487 pins. Nobody standing on a street at eleven at night is choosing between them on brand. They want the one with the ATM, or the one that is actually open, or the one with the hot food counter.
The unit of data is the shop. The unit of the decision is what is inside it. That gap is where every map on earth stops, and it is not a crawling problem â it is a collection problem wearing a crawl's clothes.
Three layers, and they are data rather than code â a shelf says what kind of place this is, a facet says whether that one is worth the walk, a tag says what it also is across every shelf.
Every fact wears its warrant. A dashed border means it was joined from a map point nearby. Solid means it was tagged. Solid and bold means a person stood there. A reader can see how far to trust a tag before they tap it.
Absence is never a claim. An untagged facet renders as nothing, never as "no". We know 92 of the 7-Elevens have a cash machine. We do not claim the other 395 lack one, and a directory that implied it would be lying quietly.
Sometimes there is only one question. The mapped answer is thin â 344 toilets mapped as toilets in Chiang Mai, 87 in Chiang Rai, and outside the old city that is close to nothing. Every map stops there and tells the reader there is nothing nearby.
So the answer is built a second way: thirteen classes of place that dependably keep one, ranked by how dependable the class is and how long its doors stay open â not by how nice the room is. Rank one is a fuel station. Each class carries who may use it (public, visitor, customer, guest), what it costs (free, small fee, free or small, with an order), and the hours its doors are open.
This is the whole method in one page: when the ground truth is thin, answer with a ranked class, say which kind of knowing it is, and refuse the answer that would waste somebody's walk.
Thirty-eight questions were put to both on 18 September. Twenty had a working link to a business in the top five of search; 8% of the links were simply gone; the most common destination was a Facebook page, and 21 of the 22 fetched refused a reader who was not logged in.
Four in five businesses here are on Facebook and fewer than one in five has a website. The commercial web of this city is behind a login. Mot Dang is the open copy, and the licence is CC BY 4.0 so anyone may take it.
Built before anyone asked. A shop owner searching their own name finds a page with their hours, their pin, their phone â and a button that says this is mine. Confirming it takes a tick and shows on the page the same second.
That last number is the opportunity, not the problem. The supply side of a directory is normally the expensive half: you must persuade a merchant to create something. Here it exists already, and the ask is one tap on a page they were going to look at anyway.
The incumbent cannot run this play. A platform needs the merchant to show up first. Mot Dang did the work first and is holding the city's commercial identity in trust until its owners arrive.
Chiang Rai is usually treated as an afterthought by everything that covers the north. Measured side by side:
On the two fields that decide whether a record can be found and shown to a Thai reader, Chiang Rai is ahead. It is a smaller province, not a thinner one.
Seven American reference directories were built in the same seventy days, on purpose, to time the machine on subjects with no local advantage â barbecue, chicken wings, pinot noir, donut shops, Basque dining rooms, cross-border care, amulets worldwide. First commit to live site: 53 hours, then 45, 45, 36, 35, 35, 35. The curve is the asset.
No servers. No tile service and no per-view map fee â the basemap is self-hosted. No data licensing. No team. A new city does not need a new anything; the same plan absorbs it.
Every assistant and agent shipping this year will be asked about this city. The answer they need is structured, licensed, sourced per field, and open to copy â and for Chiang Mai it exists in exactly one place.
Depth on the facts that decide â opening hours across the shelves people ask about with a clock in the question. The Thai-native trade registers a map never held. And telling 88,251 shop owners that their page is waiting.
The open question: what would have to be true for this to be worth backing at the size you would want to write? Say it, and the next version of this page answers it with a measurement.
