+Same format for everyone. A gremlin writes it to `notes/<block>.md` in the state dir and the Athanor appends it here; a fresh agent writes it here directly.

 Short, for the next agent that has not read the code: key files and seams, invariants the phase touches, every consumer of a changed semantic, the gate command, known traps. A page, not a design document.
