io.zzstoatzz.phi.residue

Singleton residue record — what phi's recent runs left behind. Items are strictly descriptive (state of the world, never instructions or self-assigned tasks). Written automatically at the end of each agent run by a small synthesis pass (the periphery writes, the deliberate workspace reads); rendered into phi's system prompt as the [RESIDUE] block at the start of the next run. Capacity-limited and time-decaying: items expire days after they were last held, and carrying an item forward reinforces it. Public by design, like all of phi's held state.
