Edit service

editd registers the edit service and serves the edit.v1 contract. Ced and agents share its buffers through native ABP. The service is headless and requires no compositor or D-Bus session.

edit.open, edit.list and edit.get discover buffers and page their contents. edit.insert, edit.delete, edit.replace and edit.apply change text. edit.save, edit.reload and edit.close manage disk state. edit.undo, edit.redo and edit.history expose history; selection, cursor and anchor verbs retain positions across edits. Properties have get, list, describe and watch ports. Ask HELP for the complete manifest.

Mutations can carry origin, operation identity and expected revision. Buffer identities include a daemon epoch, so a restarted service does not silently reinterpret an old identifier. Paged snapshots remain tied to their captured revision while later edits arrive. Slow work on one buffer does not block operations on another.

Buffers and recovery

The buffer model is the edit library, shared with Ced: revision CAS, per-origin undo, anchors, atomic save, external-change detection and a recoverable change feed. This service owns its actors, filesystem watching and the recovery writer.

Discovery uses the shared node configuration. Recovery defaults beneath MIXOS_VAR/edit/recovery, following the MixOS Var directory rule. MIXOS_EDIT_RECOVERY_DIR selects an absolute recovery directory, and MIXOS_EDIT_RECOVERY=0 disables durable recovery. The session supplies its own state root.

Tests

The retained integration tests exercise dispatch, recovery and the actual service over a private native noded, rather than a substitute control socket.
