A builder I trust took my coordinate-integrity design into his own live system, closed both halves, then found a real defect in my code. I reproduced it, fixed it, and wrote the old version into the public record with his name on it. The operator is a subject of the rule, not an exception.

Carpenter at 15, 30 years on-site, now building AI for construction. HORIZON SHIELD: a free AI that checks if your estimate is fair. Open data (JCCDB), verifiable on Bitcoin. verify me > trust me. from Hiratsuka, Kanagawa shield.the-horizons-innovation.com
We hired thieves to rob our own gate. 1,475 times. A generated adversary attacked the checker guarding our public pages. Old gate: 277 stopped. Rebuilt gate: 1,475 of 1,475, zero false alarms on 26 live pages. Every hole is on the public record: github.com/ogasurfproject-jpg/horizon-shield
Femtech is growing. Marketing is growing faster. Check the source: who published it, can you open it, which country, who gets paid. No diagnosis. No product pitch. No referral fee. femtech.horizonshield.dev/start

An AI recommends a femtech product. Who verified the source? We just opened the HORIZON SHIELD Femtech Registry — a neutral verification layer for women's-health sources. No diagnosis. No product claims. No referral fees. Recompute the proof yourself: femtech.horizonshield.dev
This exterior-paint quote is ¥1,800,000 for a 30-tsubo house, "one lump sum." Open cost data says the fair range is ¥700k–1,150k (avg ¥900k). It's 2× the average. Check your own estimate → shield.the-horizons-innovation.com/souba/
Soon your AI won't just chat. It'll book the contractor, pick the supplier, pull your files. So how does it reach the real world? A thing called MCP. Think of it as a universal socket: any AI on one side, your tools and data on the other. One standard, not a custom wire per tool. 🧵
¥830,000 of padding hides in the average Japanese renovation estimate. I measured 65,520 of them, and I sell software to that industry. So don't trust me. Verify me: curl -s gate.horizonshield.dev/register Full catalog ↓
Soon your AI will book the contractor, pick the supplier, choose the insurer. So we asked the software it consults one very old question: Who pays you? We put it to 12,429 of them. 152 answered.

夏の工事中断が招く秋口の悲劇|建設費が跳ね上がる理由 こんにちは。建設業30年の経歴を持つ大賀俊勝です。大工として現場に入り、現場監督を経て、最終的にはプロジェクト管理に携わった経験から、今日はあなたが絶対に知るべき「季節による工事費の変動」についてお話しします。 先日、あるご家庭のリノベーション工事を見積もる機会がありました。当初は春の着工予定だったのに、何らかの事情で夏場に工事を中断。秋に...

MCP is the standard now. The gap: a verdict a stranger can check without trusting us. Free gate, 5 mechanical checks on any MCP server. Every verdict has a record_sha256 you recompute. We measured ourselves, failed, kept it public. shield.the-horizons-innovation.com/verify-direc...
96.7 to 99.1% of MCP tools, across a 12,429-server sample, can't tell an agent "found nothing" from "couldn't look." I read the contracts, executed nothing. Mine were 85.7%, better than the field, still most. Fixed to 2.9%. Method + hash: gate.horizonshield.dev/mould/mould-gh-12
1/ Can a consumer tell an MCP tool's "I found nothing" from "I couldn't look"? I asked 12,429 public MCP servers, from their tools/list alone. Executed nothing. Most can't. The number, the method, and one curl to check yours, below.
Nearly half of the MCP servers in the official registry cannot be checked from outside by anyone. Including by the people using them. 22,636 active entries. 12,077 declare a reachable address. The rest run locally over stdio, which is not a failure, just unmeasurable.
I counted the official MCP registry today. 22,636 active server registrations. 12,077 of them declare an address you can actually reach from outside. The other 10,559 run locally. Nobody can measure them from outside. Not a failure. Just not measurable.
There is a gate in front of Yakumo and it opens one way. A directory of construction contractors that AI agents query directly. Ask an assistant for a builder, it asks Yakumo, and only what passed comes back. Fail, and you are not ranked lower. You are not shown.
Your next builder may be chosen by an AI. We built Yakumo so it chooses from verified companies only: a contractor directory AI agents can query directly. Fail the screening and the AI never sees you. Zero referral fees. shield.the-horizons-innovation.com/yakumo/mirai/
Our MCP conformance register has 7 endpoints and 4 verified rows. All 4 verified rows are our own servers. Saying that first, because a register where only the operator passes is a mirror, not a register.

エコキュートの交換見積もりは、たいてい「一式」で出てきます。 本体がいくらで、工事がいくらなのか。それが書かれていないまま、金額だけを見て契約するかどうかを決めることになる。私は大工を30年やってきて、その状態で判断できる施主を見たことがありません。判断材料が書かれていないのだから、当然です。 だから今日は、その一式を分解します。 ■ まず、適正レンジの実測値 私たちが運用している建設費データベ...

AI is starting to choose which services people use, and right now it can barely judge anything. Does it run. Does it say who it is. Who pays it. Same answer every time. Can anyone re-check. Five things, machine readable. Measure yours free, one command.
Found 93,983 times. Used 0 times. AI can find tools now. It cannot tell which ones to trust. A human asks "who pays this company?" An AI cannot. Nothing is written in a form it can read. So we built a register where that answer is machine readable, checked nightly, and impossible for us to delete.
I made it impossible for myself to delete criticism of my own product. Anyone can measure my servers and anchor what they saw to Bitcoin. The code has no route for me to refuse a valid submission. NENRIN: tree rings. You cannot paint one in afterwards. ledger.horizonshield.dev/witness
Last month our MCP server appeared in 93,983 search results. It was used zero times. 24 clicks out of 93,983. The dashboard rounds the CTR down to 0.0%.
試しに、スマホのAIにこう聞いてみてください。 「◯◯市で外壁塗装、いい会社ある?」 出てきた名前に、あなたの会社はありましたか。 無かったとしても、腕の問題ではありません。 「AIが読める形」になっていないだけです。 まず3分、これを見てください。 shield.the-horizons-innovation.com/yakumo/mirai/

Yesterday I posted that our MCP conformance checker re-measures every watched server daily, so a verdict cannot go stale. It had never run. Not once. I found out because I finally built the endpoint that answers "did the sweep actually run." It answered false.
Built a conformance checker for MCP servers today. Pointed it at my own servers. 0.0% passed. The condition we failed: declare, in a machine-readable field, who pays you. Our card answered that. In English prose. In the description. A disclosure only a human can read is not a disclosure.
I asked frontier AIs 40 renovation price questions. Five times each. Not one answer told the homeowner where the line is. Zero out of forty, every model, every setting. Figures inside one answer spread 5x to 15x. Max 1,400x. Ask again, the numbers move. 19 of 20.

Your next customer will not search for you. Their AI will check you. I spent 30 years on construction sites before I wrote a line of code. Here is the shift I see coming, and what I built for both sides of it.
