Frontend before the Rust port; v0 served by the daemon

Status: accepted · 2026-09-04

Context

KO-168 plans a Rust port module by module once the Python seams stop moving; its own trigger is a few weeks without structural change. Ko asked whether to port before or after a frontend.

Decision

Frontend first. A frontend consumes the daemon's JSON, which a Rust daemon would have to honour anyway, so it is untouched by the port. Building the client is what shapes the API (/attention exists because the drawer needed it). Rust waits until the JSON and the schema stop moving.

v0 is a page served by the daemon at /, read-only over /status, /runs, /attention and the ledger, with no build step, so it works on one machine with nothing installed. Writes come behind a serve token.

Tickets

Depends on note 13 for the page's shape.
