The adapter's _load_providers tries 4 paths in order:
1. /opt/adapter/config.yaml — provisioner-managed (currently missing)
2. os.path.dirname(__file__)/config.yaml — alongside adapter.py
3. ${WORKSPACE_CONFIG_PATH}/config.yaml — workspace overrides
4. _BUILTIN_PROVIDERS — oauth + anthropic-api only
On this template's docker image /opt/adapter/ is never populated by
the platform provisioner (verified 2026-05-08 by SSM-exec on a live
canary's workspace EC2: ls /opt/adapter/ → no such file or directory).
That makes path 2 — the dir adjacent to /app/adapter.py — the
load-bearing one for production workloads.
The Dockerfile copies adapter.py + claude_sdk_executor.py + scripts/
+ entrypoint.sh + __init__.py into /app, but it does NOT copy
config.yaml. So /app/config.yaml doesn't exist, path 2 fails, and
the adapter falls all the way through to _BUILTIN_PROVIDERS.
_BUILTIN_PROVIDERS contains only anthropic-oauth + anthropic-api.
Every MiniMax / GLM / Kimi / DeepSeek model id has no matching
prefix in those two, so _resolve_provider returns providers[0] =
anthropic-oauth (per "unknown ids fall back to providers[0]" rule).
That provider needs CLAUDE_CODE_OAUTH_TOKEN, which is unset for
non-OAuth tenants. The claude CLI fails with:
Not logged in · Please run /login
…which surfaces in the A2A response as "Agent error (Exception)".
This is the root cause of:
• Canary chronic red since 2026-05-07 02:30 UTC (38h+ at time of
investigation)
• molecule-core#129 failure mode #1
• Memory feedback_template_vs_workspace_config_separation
(template-claude-code PR #37 added the multi-path lookup but
didn't bundle config.yaml into the image — the lookup paths
point at files that don't exist)
Fix: one-line `COPY config.yaml .` in the Dockerfile.
Verification path (post-merge): publish-runtime workflow rebuilds
the image, deploys to staging tenant fleet, next canary cron run
sees /app/config.yaml → loads minimax provider → MINIMAX_API_KEY
matches → claude CLI auths → A2A returns PONG → green.
