Addresses maintainer review on the OpenAI-compatible endpoints PR:
1. CLI: accept --backend azure_openai in skillopt_sleep/__main__.py (the
documented command was rejected by the argparse choices).
2. Example runner: exit with the child's return code so watchdog/supervisors
see a failed sleep run as a failure.
3. Error state: clear last_call_error when a retry recovers; set an explicit
"empty response on all N attempts" diagnostic when every attempt returns
empty text.
4. Security guard: the managed-identity path now refuses to send an Azure AD
bearer token to any endpoint outside *.openai.azure.com /
*.cognitiveservices.azure.com — a custom endpoint requires explicit
AZURE_OPENAI_AUTH_MODE=openai_compatible + API key.
5. Provider-neutral requests: compat mode sends only the standard contract
(max_tokens, default 8192 via SKILLOPT_SLEEP_COMPAT_MAX_TOKENS);
provider-specific body fields are opt-in via SKILLOPT_SLEEP_CHAT_EXTRA_BODY
(JSON) — the deepseek model-name inference is removed.
6. Docs: removed the unimplemented OPTIMIZER_*/TARGET_* env-var claim; added a
configuration reference matching the implementation exactly.
7. Tests: tests/test_azure_openai_compat.py — 17 deterministic no-network
unittest cases covering CLI acceptance, compat-vs-Azure client selection,
endpoint resolution, the credential guard, request kwargs (opt-in extra
body / token cap), retry-success error clearing, empty-response
diagnostics, and runner exit-code propagation.
Re-verified live against DeepSeek (deepseek-v4-pro, openai_compatible mode)
after the rework: client type OpenAI, completion returned, no error state.
