[lib-audit] R2-8 summary/category calls POST to endpoints no backend serves - #2966
Conversation
…/completions
R2-8: _summarise POSTed to {base}/generate and _llm_categorise POSTed the
bare base URL. Neither path is served by any backend. Both failures were
swallowed, so items were marked ready with empty summaries and no categories.
Route both through the OpenAI-compatible /v1/chat/completions endpoint via
the existing http_client. Surface LLM failures as item status partial with
the error stored in metadata rather than silently marking ready.
Tests added:
- test_summarise_uses_chat_completions_endpoint
- test_summarise_failure_sets_partial_status
- test_category_llm_failure_sets_partial_status
- test_llm_categorise_uses_chat_completions_endpoint

[SUGGESTION]: Move import json to the top of the file
Importing json inside the _llm_categorise method is a code smell. It should be imported at the top of knowledge_categories.py alongside the other imports.

[WARNING]: categorise no longer catches exceptions from _llm_categorise
The old code wrapped the _llm_categorise call in a try/except that returned an empty list on failure. Removing it changes the exception contract of this public method. The current caller (IngestPipeline.run) handles the exception, but any external caller relying on the previous exception-safety will now see unhandled exceptions.

[WARNING]: _llm_categorise no longer catches exceptions internally
The old code had a try/except around the HTTP call that returned [] on any failure. Now HTTP/network errors propagate instead of being swallowed. The caller (IngestPipeline.run) handles them, but this changes behavior when _llm_categorise is called directly.

[SUGGESTION]: Log a warning when the LLM returns an empty choices array
The old code logged a warning whenever the LLM response lacked the expected fields. The new code silently falls back to [] when choices is empty. Consider adding a debug/warning log so operators can distinguish between an LLM that returned no categories and one that errored.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Isolate the categorisation failure.
IngestPipeline.run() continues to summarisation after CategoryEngine.categorise() fails. The shared failing llm_response makes both calls fail, so status == "partial" does not independently cover the categorisation-error path. Set llm_base_url="" while keeping CategoryEngine.llm_url configured, or return a successful response for the second POST. Also assert metadata["llm_category_error"].

🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win
Keep knowledge.item.ready exclusive to ready items. run() marks LLM failures as partial, then always calls _notify(). _notify() sends knowledge.item.ready to matching subscriptions, or a generic notification when none match. That notification has no status field, and the generic message says, “Item ... is ready.” Call _notify() only for ready items, or emit a separate partial-status event.
