The deliverables subagent runs its own generate_image/podcast/report/resume/
video_presentation (via tools/index.py); the shared/tools copies had zero
production importers — classic dead twins. Removed them so deliverable tools
live only in their vertical slice.
While repointing the 2 stranded unit tests at the LIVE deliverables modules,
found the OpenRouter empty-api_base defense (resolve_api_base) existed ONLY in
the dead shared generate_image, never propagated to the live multi-agent copy.
Ported the fix into deliverables/tools/generate_image.py (both the global-config
and user-DB-config branches) so an empty api_base no longer falls through to
LiteLLM's global api_base (Azure) and 404s.
Tests now exercise the live Command/receipt-returning tools (invoke the raw
coroutine with a hand-built ToolRuntime; resume progress events neutralized).
