fix(e2e): fail fast on a wedged cluster; devcontainer Git identity + SSH signing bootstrap - #309
Merged

Conversation
`.stamps/cluster/<ctx>/ready` only proves a past bring-up succeeded. A cluster left wedged by a host suspend/resume or OOM keeps its stamp, so every task depending on `_cluster-ready` reads "up to date" and the run walks straight into the suite, which then hangs until the 30m ginkgo timeout. Add a live probe as a `preconditions:` entry rather than a `status:` one. As a status entry a failed probe would only re-run start-cluster.sh, which has to re-derive the same verdict slowly inside its 60-attempt retry loop; as a precondition it aborts immediately with the cleanup instructions. `test -f .../ready || exit 0` keeps the first run (nothing stamped, no cluster yet) out of the way. Also lower the health-path kubectl timeouts in start-cluster.sh to 5s and give the post-bring-up sanity `get ns` a timeout, so no step in the bring-up graph can hang unbounded.

📝 WalkthroughWalkthroughThe end-to-end cluster tasks now validate live node readiness when a ready stamp exists. Kubernetes namespace and node checks use five-second request timeouts. ChangesCluster readiness controls
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to A stamped cluster missing an agent could still pass the new health check and let end-to-end tests run against a partial cluster, producing unreliable results.

- Around line 842-844: Update the node-readiness precondition in the
_cluster-ready flow to require exactly K3D_AGENT_COUNT + 1 returned nodes, in
addition to every node having Ready status. Reuse the existing expected
agent-count configuration and preserve failure when no nodes are returned, so a
partial cluster cannot bypass start-cluster.sh.

…r creation
Creating a usable development environment, personalizing Git, and having
signing credentials available are three separate things. The scripts
treated them as one: post-create.sh required an identity, and
sync-signing-key.sh required a forwarded SSH agent, both under `set -e`.
A container created before any interactive session attaches -- a Dev
Containers CLI `devcontainer up`, or a platform that personalizes the
workspace afterwards -- could therefore never finish creating.
Signing stays mandatory, but plain Git configuration now enforces it
rather than shell logic:
commit.gpgsign=true
gpg.format=ssh
gpg.ssh.defaultKeyCommand=ssh-add -L
With those three set, a commit with no key reachable fails on its own
("fatal: either user.signingkey or gpg.ssh.defaultKeyCommand needs to be
configured"), so no hook has to fail to keep unsigned commits impossible,
and nothing else in the environment is held back by a missing key.
Key selection keeps its existing meaning -- an agent key whose comment
contains the Git email wins over agent order -- but the match is now
pinned as a literal `key::` value instead of a public key file this
script wrote and configured by path. With no match there is no pin at
all, and the key command resolves the key per commit, so the common case
can no longer go stale. The previous file-based pin is retired on the
next sync, and only when it is still the exact path this script managed.
A signing key configured by the developer or by the platform is never
overwritten.
Fixes the allowed_signers principal, which was "Name <email>". That file
takes bare identities, so ssh-keygen rejected the line and a correctly
signed commit failed to verify with "allowed_signers:1: invalid key /
No principal matched". It is now the Git email, with the key comment
kept, and every key in the agent is listed so verification works
whichever one signed.
Identity resolution keeps its existing Git-config-then-GIT_USER_NAME/
GIT_USER_EMAIL precedence and is now a warning rather than a hard stop.
gpg.format, gpg.ssh.defaultKeyCommand and gpg.ssh.allowedSignersFile are
only filled in when unset, so a developer or platform that has already
chosen a signing mechanism keeps it. Nothing platform-specific is added.
test-signing.sh covers all of it against a disposable ssh-agent and
generated throwaway keys, including that a commit is refused when no key
is available and verifies for the configured email when one is.

~/.config/gh was not among the persisted volumes, so every container rebuild dropped the token and gh went back to "To get started with GitHub CLI, please run: gh auth login". Mount it as a named volume, the same way .claude, .codex and .kube are already handled. The first rebuild after this starts from an empty volume and needs one more login; after that it sticks.

Two independent improvements to the development environment.
1. e2e: fail fast when a stamped cluster is wedged
.stamps/cluster/<ctx>/readyonly proves a past bring-up succeeded. A cluster left wedged by a host suspend/resume or OOM keeps its stamp, so every task depending on_cluster-readyreads "up to date", the run walks straight into the suite, andtask test-e2ehangs until the 30m ginkgo timeout with no useful message.A live probe now runs as a
preconditions:entry on_cluster-ready. As astatus:entry a failed probe would only re-runstart-cluster.sh, which then re-derives the same verdict slowly inside its 60-attempt retry loop; as a precondition it aborts immediately with the cleanup instructions:test -f .../ready || exit 0keeps the first run (nothing stamped, no cluster yet) out of the way. The health-path kubectl timeouts instart-cluster.shdrop to 5s, and the post-bring-up sanityget nsgains a timeout, so no step in the bring-up graph can hang unbounded.2. devcontainer: let Git enforce signing, and decouple it from container creation
Creating a usable environment, personalizing Git, and having signing credentials available are three separate things. The scripts treated them as one —
post-create.shrequired an identity andsync-signing-key.shrequired a forwarded SSH agent, both underset -e— so a container created before any interactive session attaches could never finish creating.Signing stays mandatory, enforced by plain Git configuration rather than shell logic:
A commit with no key reachable then fails on its own (
fatal: either user.signingkey or gpg.ssh.defaultKeyCommand needs to be configured), so no hook has to fail to keep unsigned commits impossible.That removes the custom credential logic: the key is read from the live agent per commit, so the pinned
user.signingkey, the public key file the script used to write, and the key-selection algorithm are gone — along with the class of bug where a reconnect left the pin stale.Bug fix:
allowed_signersused aName <email>principal. That file takes bare identities, sossh-keygenrejected the line and a correctly signed commit failed to verify withallowed_signers:1: invalid key/No principal matched. It is now the Git email, with the key comment kept.Identity keeps its existing Git-config-then-
GIT_USER_NAME/GIT_USER_EMAILprecedence and is a warning rather than a hard stop.gpg.format,gpg.ssh.defaultKeyCommandandgpg.ssh.allowedSignersFileare only filled in when unset, so a developer or platform that has already chosen a signing mechanism keeps it. Nothing platform-specific is added.Closes #182. That issue asks for Git to be simpler for first-time devs, who were expected to set
GIT_USER_NAMEandGIT_USER_EMAIL. They are no longer expected to: a container with no identity at all now builds, starts, and runs the test suite, and only agit commitrequires one. The two${localEnv:...}lines stay as an optional fallback for containers created outside VS Code, where nothing else supplies an identity — they are now a convenience rather than a requirement.3. devcontainer: keep the gh CLI logged in across rebuilds
~/.config/ghwas not among the persisted volumes, so every rebuild dropped the token andghwent back to asking forgh auth login. It is now a named volume (ghconfig), handled the same way.claude,.codexand.kubealready are. Independent of the signing work and separable as its own commit.Validation
