# V3 Phase 15 — G15a CSI Static MVP Mini-Plan
**Date**: 2026-05-03
**Status**: G15a-1/2/3 implemented; G15a-4 binary-start slice implemented; G15a-4 privileged NodeStage L2 and G15a-5 pending
**Status**: G15a-1/2/3 implemented; G15a-4 non-privileged ControllerPublish L2 implemented; G15a-4 privileged NodeStage L2 and G15a-5 pending
**Branch**: `p15-g15a/csi-static-mvp` off `origin/phase-15`
**Goal**: make Kubernetes CSI consume an already-provisioned V3 block assignment and mount it through the Linux node path.

`blockvolume frontend -> heartbeat observation -> master QueryVolumeStatus -> CSI ControlStatusLookup`.
This closes option 1 for the first iSCSI attach backend.
- `94ff9cf` added `cmd/blockcsi`: CSI Identity/Controller/Node services, endpoint binding, and read-only master status lookup wiring.
- `ac49adb` added the non-privileged ControllerPublish L2:
real `blockmaster + 2x blockvolume + blockcsi`, with `ControllerPublish` returning the iSCSI frontend fact reported by blockvolume.
