The rules every system is held to, written before the work rather than after it.
Spec before code
Ownership contracts, isolation boundaries, and control-plane designs get written, dated, and reviewed before anything is built. More work at the start; fewer mistakes later.

One writer per surface
Concurrency gets a lease, not a hope. A single writer per path — across multi-agent workspaces and down to the lighting stack on this laptop — enforced by architecture, not discipline.

Receipts, never adjectives
Every material action runs inspect → checkpoint → change → real probe → receipt. If a probe was not possible, the result is UNTESTED — never PASS.

Failures leave evidence
Every failed run records a failure receipt: exit code, output, timestamp. Behind it sits a checkpoint that can be restored, so nothing disappears quietly and nothing is retried blind.
