Fix generate_nav tenant mismatch: wipe used dataset owner's tenant_id but rebuild used caller's. Team members could delete owner's navigation tree and rebuild into their own. Now both use kb.tenant_id.
### What problem does this PR solve?
Closes#18116.
Fix cross-KB document ID collision (#18116). Older ID derivation excluded kb_id, causing two KBs to fight over one row. Unified derivation to be KB-scoped, with fallback for existing rows. Stranded rows are reclaimed, dataset deletion now cleans up state, and upgraded instances update in place. Tests added.
### Summary
Closes#17848.
This replaces #17958 with a smaller implementation focused on the
original requirement. The previous PR gradually expanded beyond the
necessary scope; the optional custom endpoint extension is intentionally
excluded from this version.
- Add request-scoped Bedrock API key authentication to the Python
Bedrock adapters and Go chat runtime.
- Discover and persist models available to API key instances, so users
do not need to manually enter the model type, model name, or maximum
token count.
- Add API Key mode to the existing Bedrock settings UI and refresh the
model and default-model lists after instance changes.
- Preserve selected models during credential-only updates while keeping
the existing SigV4 authentication modes unchanged.
- Return a clear error for unsupported API-key reranking.
- Document instance-scoped authentication and short-term API key
guidance.
Two fixes not yet on main:
Pass picker-selected models into Verify – useVerifyProvider now includes modelInfoRef in the verify payload so the backend can verify the user's actual selection.
Guard model construction – Wrap EmbeddingModel/ChatModel init in try/except so failures are recorded as per-model FAIL instead of aborting the whole verify call.
Also: later failures now overwrite previous successes per review feedback.
### Summary
Providers whose static catalogue is empty discover their models by
calling the base URL the user typed. `verify_api_key` wrapped that call
in a bare `except Exception: pass` and then returned a flat `No models
found for provider 'X'`, so an unreachable host, a closed port, a wrong
scheme and a bad TLS setup all produced the same sentence, with the
actual error discarded and not even logged.
### What problem does this PR solve?
Incremental Wiki compilation could lose provenance for claim-light
entities, produce unstable page groups across embedding models, route
entities to unrelated pages, and assign topics without sufficient
page-level context. Document removals and page membership changes could
also leave stale Wiki state.
This PR:
- preserves source document and chunk provenance throughout entity
matching, reduction, page generation, and deletion;
- uses embeddings to retrieve candidates and the LLM to make final page
grouping and incremental routing decisions;
- batches embedding and LLM operations with bounded concurrency and
deterministic fallbacks;
- selects source-scoped topic candidates with embeddings before the page
LLM chooses the final topic;
- rebuilds Wiki state when the compilation mode or embedding model
changes;
- normalizes Wiki array fields returned by the API and retains entities
without relations in graph responses.
