Mirrors agent-runtimes audit + fix. All three M22 Phase 9 wrapper-script
auth paths were broken since the cutover: each one ran as the agent UID
trying to `cat` a 0400 root-only ESO mount. Same root cause we hit on
minimax/z-ai earlier today.
Changes:
1. anthropic-cloud-paul-oauth/v1 (NEW in framework)
- Mirrors agent-runtimes — was previously only present there.
- init.sh stages oauth_token into ~/.claude/.credentials.json (Claude
Code's native subscription-OAuth schema). No env, no apiKeyHelper,
no wrapper. Restores the equivalent of what harness_init.py used to
do for the legacy SOPS path.
- The legacy `bin/anthropic-wrapper.sh` was dead code (never wired).
2. gitea-https/v1
- init.sh stages the token to $HOME/.config/git/gitea-https-token
(0600 agent:agent) and points the per-host git credential helper at
the staged copy. Previously the helper `cat`d the ESO mount path
and silently failed at every git invocation.
3. gitea-admin/v1
- init.sh stages the token to $HOME/.config/gitea-admin/token
(0600 agent:agent). Wrapper updated to read from the staged copy.
- Removes stale `requires: anthropic-cloud/v1` (the only anthropic
harness in agent-runtimes is anthropic-cloud-paul-oauth/v1).
Pattern matches gitea-ssh / minimax / z-ai: ESO mount stays root-only,
init.sh runs as root and `install -m 0600 -o agent -g agent`s a single
explicit copy. Per-secret enumeration; future ESO Secret keys remain
inaccessible by default.

# Threat model: keep the ESO mount root-only (mode 0400). init.sh runs as
|

# root and `install`s a per-secret 0600 agent-owned copy at
|
|
# $AGENT_HOME/.config/git/gitea-https-token. The git credential helper

# is never accessed by the agent.
|
|
#
|
|
# This was previously a `cat /run/agent/secrets/gitea-https/token` from
|
|
# inside an init.sh-generated helper script, which silently failed because
|
|
# the helper runs as agent and the ESO file is root:root mode 0400. The

|
|
# z-ai / anthropic-cloud-paul-oauth.
|
|
#
|
|
# Rotation handling: per-container init. Ephemeral container agents
|
|
# always pick up the latest mounted token. Long-running sessions need a
|
|
# future scripts.control_loop hook to re-stage between git invocations.
