The autonomous "review comment → respawn bottle with comment as
next prompt" loop is the one feature that opens a prompt-injection
vector the bottle wall can't close (a public commenter would get
to issue instructions inside the agent's perimeter on every
launch). The available mitigations — commenter allowlists,
prompt-injection regex screens, private-repo defaults — are all
soft. The durable defense is to keep the human between the
review comment and any next agent prompt.
So `supervise` is now strictly notify-only. The `auto_respawn`
manifest field, the "with auto_respawn: true" behavior paragraph,
and the matching trust-model edge case all go. The reasoning
stays in the "Where to be conservative" bullet so the decision
isn't re-litigated later.
