/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.

* fix(gateway): answer client-aborted requests with 499, not a traceback
A browser reload, back navigation or proxy timeout can abort a request while
its body is still arriving. Starlette then raises ClientDisconnect from
request.stream(); nothing caught it, so ServerErrorMiddleware logged a full
ERROR traceback per aborted request and buried real faults. The request never
reaches DSH (the body is buffered before the upstream send) and the peer can
no longer be answered, so this is not an error.
- Register a ClientDisconnect exception handler that answers 499
(CLIENT_CLOSED_REQUEST). One handler covers the proxy and the body-reading
control routes (signup, login). A request already streaming keeps its
upstream status because the response has started.
- Make _release await-free, and reach it even when the upstream close is
cancelled. CancelledError is a BaseException, so suppress(Exception) around
upstream.aclose() skipped the release and stranded the in-flight slot,
leaving that user's sandbox looking busy forever (the idle sweeper then
never suspends it).
- Add raw-ASGI regression tests: mid-body abort on the proxy and on signup,
mid-stream abort, a cancelled release, and a cancelled upstream close.
- Document the 499 semantics in the gateway README failure table and the
architecture failure modes.
Verified: make check, make test (114 passed), make lint. Against the pinned
uvicorn 0.54 the abort reproduces the original traceback before the fix and
logs no traceback after it.
* chore(deps): bump gateway starlette to 1.10.0 and ruff to 0.17.2
Absorbs Dependabot PR #27 against current main: that branch predates the
dsh-v0.2.1-rc.5 changelog/release commits, so merging it as-is would have
reverted them.
starlette 1.10.0 reworks URL-encoded form parsing (fields are built in the
parser callbacks, and the last field is kept when the stream ends without an
empty chunk) and clears tracebacks of handled exceptions. The gateway reads
JSON and form bodies, so the existing suite exercises signup/login forms and
the 499 client-abort path against the new release. ruff 0.17.2 only adds
preview and fix-safety changes; the configured rule set reports nothing new.
Verified: make check, make test (114 passed), make lint, make gateway (image
builds on python:3.12-slim and imports starlette 1.10.0), plus a direct ASGI
abort probe under 1.10.0 (499, in-flight slot released, nothing forwarded).

Bump DSH_VERSION to dsh-v0.2.1-rc.5 and clear RELEASE_REVISION, making the release identity dsh-v0.2.1-rc.5. Update every derived manifest, image tag, and doc, and remove prose that described the previous identity's legacy-tag history.

agent-sandbox v1.0.8 adds spec.failedPodPolicy to Sandbox and
SandboxTemplate. The default, Retain, leaves a Failed Pod in place and
surfaces Finished=True; Recreate deletes it and starts a replacement with
the same Sandbox identity and PVCs.
Ship it as an opt-in toggle next to the other commented fields, with a
new section 5 in the optional-hardening doc: what it changes, how to
enable it for new, warm-pool and already-claimed Sandboxes (the policy is
stamped at creation), a failure drill, caveats and rollback. The base
walkthrough stays on Retain because a deterministic failure would
otherwise recreate forever, and because the templates use
restartPolicy OnFailure, so the policy only matters for terminal cases
such as node eviction.
Cross-references updated in the example README, the optional-manifests
index, the architecture failure-mode table and the platform skill's
troubleshooting table.

Update AGENT_SANDBOX_VERSION to v1.0.8 and the docs that quote the
control-plane pin (example prerequisites, architecture, versioning table,
minimal-single-tenant template comment, platform skill).
The v1.0.8 release adds only one CRD field, spec.failedPodPolicy
(Sandbox and SandboxTemplate, enum Retain|Recreate, default Retain), so
the existing manifests keep their behavior: Retain is the default and
neither the API version (v1beta1) nor any field we set changed. All five
custom resources still validate against the v1.0.8 CRD schemas.
Behavior changes in the controller itself (bounded MCP output, router
kustomization, creation-latency metric timing) do not affect the
platform because it uses neither the sandbox-router nor the MCP server.

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.

* feat(repo)!: restructure around the dsh-harness image and one example per implementation
- the root Dockerfile is the primary artifact; versions.env is the single source of truth
- merge gateway-api/dsh-demo into examples/dsh-agents-as-a-service (manifests/, exposure variants)
- move the single-tenant template into examples/minimal-single-tenant
- publish the gateway as a nested package under the repository image
- mirror the DSH ref for release identities (first release dsh-v0.2.1-rc.2-r2)
- CI: lint/python/manifests/gateway-image, reusable multi-arch build, tag-driven release, weekly e2e
- docs: README, docs/{main-image,examples,gitflow,versioning}, example READMEs, AGENTS.md, governance
- SSO is opt-in again; gateway pull policy and cookie defaults match the documented demo
BREAKING CHANGE: example manifest paths, the gateway image name, and the removal
of deploy/ and gateway-api/ affect existing deployments; see the migration table
in README.md.
* docs(changelog): generate initial changelog from history
* fix(scripts): make set-version update Dockerfile and sample revision pins
* build(hadolint): document intentional lint exceptions for the main image
