# V3 Phase 15 G15d Mini-Plan — BlockVolume Launcher MVP
Date: 2026-05-03
Status: planner + renderer + node inventory + replica-id materialization slices landed on `p15-g15d/blockvolume-launcher`

- `--cluster-spec` can now carry node/pool inventory and blockmaster imports it into lifecycle node registration before the product loop runs
- master-side workload planning tick converts blank-pool placements into concrete replica workload identities and writes those replica IDs back as existing-replica placement intent
- dynamic-volume assignment subscriptions can fall back to lifecycle placement slots when static accepted topology does not yet contain the volume
- `blockmaster` can run an optional launcher loop that writes rendered blockvolume Deployment YAMLs to `--launcher-manifest-dir`; it does not call `kubectl apply`

- Test generated args include `--volume-id`, `--replica-id`, `--data-addr`, `--ctrl-addr`, durable root, and optional iSCSI listen.
G15d-C — Apply loop:
- Add a narrow launcher runner that applies generated workload specs.
- First implementation may shell `kubectl apply -f` or write manifests for QA to apply.
- It must be idempotent.
- It should call the materialization seam after rendering/applying concrete blockvolume workloads, but before expecting those workloads to subscribe successfully.
- DONE for write-manifest mode: `blockmaster --launcher-loop-interval=<d> --launcher-manifest-dir=<dir>` renders workload manifests idempotently.
- Still pending for K8s automation: a shell/script stage that `kubectl apply -f <dir>` after the manifests are written.
- The writer intentionally stops before apply so QA can inspect exact Deployment YAML before the cluster mutates.
G15d-D — M02 dynamic PVC:
- `StorageClass` + PVC without hand-written PV.
