docs(fase2): 3 /trekresearch briefs — installed-source-verified [skip-docs]
Topic 1 (HITL): native HITL is GA (ctx.request_info/@response_handler/
run(responses=); GroupChatBuilder.with_request_info → AgentApprovalExecutor),
but durable checkpoint-resume is fragile (open #5818/#6127/#6372 into 1.9.0)
→ capture verdict out-of-band in VerdictStore, defer checkpointing off MVP path.
Topic 2 (MCP citation): REVERSES brief lean — official server-filesystem cannot
cite (raw text + bare paths) → build thin custom local-folder MCP server
returning {file,locator,snippet,score} over a framework-agnostic in-process
retriever (D7 seam). Corrected docs error: ContextProvider(source_id) +
before_run/after_run + extend_instructions(source_id,...) DO exist in 1.9.0.
Topic 3 (local chat client): use OpenAIChatCompletionClient(base_url) NON-STREAMING
(not OpenAIChatClient/Responses) — installed, 0 new deps, UsageDetails None-safe
and populated non-streaming. Native OllamaChatClient is --pre fallback (spike-gated).
validator-as-retry mitigates weak small-model tool-calling; Intel-CPU = plumbing only.
All grounded in installed 1.9.0 source (source wins over Learn docs). Gemini
bridge unavailable (MCP SDK predates Google May-2026 API change).
