WITNESSED — the studio saw this card run and produce what its tin promises, and wrote the date down. What the marks mean →
What it is.
A machine-readable coordinate written into every artifact a card cuts — time, place, depth, reach, direction, scale, witness, light — computed from the record by published rules, hashed into the manifest, and a ninth line that lists what the record does not contain. The stamp that travels with the work and says what's missing.
Working name RÚMTÍÐ, under clearance. The stamp is the mechanism; the doctrine it measures is sealed and is not in the box. Signing under the studio key is declared, not yet built.
What’s in the buy.
rumtid.py — the stamp as a standalone function, standard library only
RUMTID.json — the spec, with every axis and its rule
ON EVERY DOOR · A CARD FOR YOUR AI, A FILE FOR YOUR COMPUTER
This card is an Agent Skill on the open standard: the same folder loads unmodified in Claude, ChatGPT and Codex, Copilot and VS Code, Cursor, Gemini CLI, Goose, OpenCode and the rest of the showcase. Its words are Markdown, so any chat with an instructions box holds them, any local model runs them offline, and any MCP client can load them — THE UNIVERSAL CUT: a pasteable system card, the rules-file family, an Ollama Modelfile, an MCP server, all cut from this card’s own SKILL.md by THE CARD FORGE. The universal cut joins this card’s box as its package is re-cut. And card.html — the card as one file for your computer: both faces, the tin, the words, every door; offline, in any browser. The machines aboard run wherever the host can run Python; the words run everywhere. The host marks →
Take it.

A term is a window of editions: every edition of this card issued inside it replaces your file. When the window closes, the file you hold keeps working — freeze, not loss. Nothing auto-renews; come back and take another term when you want the next editions.
