Closes#178.
The backend provision functions now receive a Bottle handle with
exec / cp_in methods instead of a raw target string. Provisioner
modules use bottle.exec and bottle.cp_in in place of inlined
subprocess.run(["docker", "exec"/"cp", ...]) and direct
_smolvm.machine_cp / machine_exec calls. This decouples the
provisioners from backend-specific runtime primitives so future
refactors (e.g. the supervise rework) can swap the bottle's exec
implementation without touching every provisioner.
Each launch.py constructs the Bottle handle before calling
provision so it can be passed in; provision_prompt's return value
is wired back onto the bottle's prompt path attribute after the
fact.
Debugging a live codex smolmachines bottle surfaced three independent
failures past the sign-in screen; fix each so forward_host_credentials
works end to end:
- codex_auth: dummy access/id tokens now inherit the *real* host token's
exp instead of now+1h. Codex (0.135) refreshes when its local token's
JWT exp lapses; with a placeholder refresh_token that refresh fails and
drops to the sign-in screen. Aligning exp tracks the real token's life.
- prepare: set CODEX_CA_CERTIFICATE to the agent CA bundle for codex
bottles. Codex is rustls and ignores the system store / NODE_EXTRA_CA_
CERTS; it reads CODEX_CA_CERTIFICATE (fallback SSL_CERT_FILE) for custom
roots across HTTPS + wss, so it must be pointed at the egress MITM CA or
injection can't work without tls_passthrough.
- pipelock: auto tls_passthrough the Codex API hosts when
forward_host_credentials is on. Egress injects the bearer before
pipelock, whose header DLP then flags the JWT ("request header contains
secret") and the retry storm trips its 429. passthrough host-gates the
CONNECT but skips decrypt+rescan of egress-owned auth. The auto-added
routes aren't in bottle.egress.routes, so the hosts are added explicitly.
