Two failure-clarity paper cuts from the cred-proxy debugging:
1. Every docker create / start / network-connect call on the three
sidecars (pipelock, git-gate, cred-proxy) was piping stderr to
DEVNULL. A stuck orphan from a previous run produced "failed to
create pipelock sidecar claude-bottle-pipelock-demo" with no
pointer at the real cause ("Conflict. The container name ... is
already in use ..."). Switch each call to capture_output=True and
include the stripped stderr in the die() message.
2. The agent container had a container_exists() probe in resolve_plan
that fails fast with a hint, but the sidecars (whose names are
deterministic from the slug) didn't. So an orphan caused launch()
to bail deep inside docker create. Add a probe in resolve_plan for
each sidecar this launch will actually try to create: pipelock
always; git-gate when bottle.git is non-empty; cred-proxy when
bottle.cred_proxy.routes is non-empty. Die with a "./cli.py
cleanup" pointer.
Smoke-tested with an orphaned pipelock-<slug> container — the new
probe fires with the expected hint before any sidecar build/start
work begins.
