The showcase framework directories better reflect their role as
integration examples rather than distributable packages.
Renames showcase/packages/ -> showcase/integrations/ and updates
the test docker-compose file reference accordingly.
Add *.wav to .gitattributes so audio assets follow the same LFS policy
as the existing *.png / *.pdf / *.gif / *.jpg / *.jpeg / *.mp4 / *.webm
rules. Re-stage sample.wav so the committed object becomes an LFS
pointer instead of a raw 87 KB blob.
Replace the OPENAI_API_KEY-hardcoded credential guard with a provider-aware
_check_key that inspects LANGROID_MODEL's prefix and probes the correct env
var for that provider:
- openai/ → WARN (not a langroid-native prefix; use bare model names)
- anthropic/ → WARN (not routable; suggest litellm/anthropic/<model>)
- litellm/anthropic/ → ANTHROPIC_API_KEY
- gemini/ → GEMINI_API_KEY
- openrouter/, groq/, cerebras/, glhf/, minimax/, portkey/, deepseek/ → dedicated keys
- ollama/, local/, vllm/, llamacpp/ → NO_KEY_REQUIRED (local inference)
- langdb/, litellm-proxy/, litellm/<non-anthropic>/ → NO_KEY_REQUIRED_* (credentials
resolved via config, not env)
Under REQUIRE_LANGROID_API_KEY=1 a missing credential FATALs the boot; the
default is warn-and-continue so dev containers boot cleanly.
Process lifecycle hardening:
- Use process substitution `> >(sed ...)` instead of pipelines so $! captures
the real python/next PID (not sed's) — prior pipeline pattern would mask
uvicorn crashes behind sed's exit code
- Trap cleanup with `set +e` at entry (trap may fire from FATAL `exit 1` path
where set -e would otherwise abort the cleanup loop)
- 5s SIGTERM→SIGKILL grace window on the surviving child
- Extended exit-code case statement (0, 1, 2, 126, 127, 130, 137, 139, 143, 255)
- Survivor-kill diagnostics distinguish EPERM from ESRCH
- wait -n with explicit positional PIDs so unrelated subshell reaps can't
satisfy the wait
.env.example updates document the multi-provider options so operators
discover them from the file itself, not entrypoint.sh.
.gitattributes enforces LF on *.sh so Windows contributors regenerating
the starter don't silently ship CRLF entrypoints.
SVG files are text-based XML averaging ~218 bytes each. LFS tracking
adds per-file HTTP fetch overhead with no storage benefit, suppresses
git diff output, and breaks tutorial clone instructions that use
GIT_LFS_SKIP_SMUDGE=1 (users get LFS pointers instead of icons).
