/workspace - the DSH image's WORKDIR, where agents keep files - was plain
container storage, so every suspend/resume or pod replacement silently threw
agent work away while DSH state survived on the PVC.
Mount the same per-sandbox `dsh-home` PVC a second time at /workspace with
`subPath: workspace`. One PVC, no extra provisioning, and the subPath keeps
DSH state (sessions, config and .credentials.yaml at the volume root) out of
the agent-visible tree; mounting the volume root at /workspace would have
exposed the credential file.
The kubelet creates the missing subPath directory itself and chmods it to the
volume's fsGroup permissions, and the volume root's setgid bit makes the new
directory inherit gid 1000, so UID 1000 can write with no init container and
no root. The rare interrupted-kubelet case that leaves 0755 is documented with
a recovery procedure (kubernetes#142464) rather than papered over.
- e2e-kind: write a /workspace marker alongside the DSH_HOME marker, assert
the mount is the dsh-home subPath, and verify both survive suspend/resume.
- Docs: README (overview, steps 4-6, troubleshooting row), architecture
(PVC diagram, persistence, component table), main-image working-directory
row, platform runbook PVC row.
Verified: make check (14 manifests), make lint, plus YAML assertions on the
two mounts and the unchanged volumeClaimTemplates.

Add opt-in hardening to the agents-as-a-service example:
- commented runtimeClassName/nodeSelector fields for sandboxes and Deployments
- optional sandbox NetworkPolicy plus exposure-variant policies
- optional dsh-provider-keys-extra Secret for extra provider keys
- docs/optional-hardening.md with verification, caveats and rollback
The base walkthrough stays portable; no gateway code, routes or auth changed.

Add the project-local dsh-agent-sandbox-platform skill covering platform operations, the optional agent-sandbox MCP server, feature-extension recipes, and a read-only preflight. Document project skills in README, docs and AGENTS.md.
