Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟠 High · up to A provider-originated HTTP 409 can be converted into a generic failure before terminal handling, potentially causing a state-changing operation to be retried or re-executed and preventing the documented 409/SSE response. This high-impact correctness risk should be fixed before merge. Sequence Diagram(s)sequenceDiagram

Applied the raw provider boundary follow-up at exact head
This keeps #771 safe when stacked with the provider boundary in #807. Please review this exact HEAD; merge remains gated by independent approval and protected Checks. |

Exact-head status refresh for PR #771\n\n- Live head: cc806cd\n- Base: e226e11\n- The branch advanced after the prior e258875 audit; all predecessor evidence is stale for merge decisions.\n- Current required workflows were newly queued at 2026-08-21T12:12:15Z; approvals remain 0.\n- Current-head review contains a valid provider 409 tool_execution_stopped boundary finding and a direct-run coverage finding. A local successor commit 276ed4f addresses both and passes focused 114, direct fallback 96, and full 1538 tests, plus compileall/actionlint/diff-check/Semgrep/pip-audit.\n- The normal push of that successor was rejected by active ruleset 18156473 because changes must be made through a pull request and the required workflows for the new head are not yet satisfied. No bypass, direct protected push, or stale evidence reuse was used.\n- Repository coverage remains 90% statement with 146 partial branches and docstring coverage 95.9%, below the 100% standard.\n- Decision: WAIT_AND_REMEDIATE. |

* fix: extend provider error boundary to streaming and batch paths - _stream_send: mid-stream failures surface one package-owned error; the terminal tool-stop SSE contract is preserved (CWE-209) - batch_chat: upload/poll/download failures no longer leak raw urllib text - model discovery: raw connection resets (OSError, non-URLError) map to the stable transport_error code - ADR 0011: document the streaming/batch boundary extension Supersedes the still-valid delta of #807 after #771 landed the core boundary. * fix(orchestrator): tolerate empty or missing choices in SSE streams A provider usage-only frame can emit choices: [] or omit choices entirely. The previous raised IndexError when the key existed but the list was empty, and the broad provider error boundary would then abort an otherwise valid stream. Normalise the choices list before indexing and add a regression test covering both empty and missing choices.

Buyer-visible outcome
A missing tool no longer terminates an otherwise recoverable workflow, while uncertain state-changing outcomes are stopped safely.
