fix(gateway): keep virtual selectors on Fugu route/conduct - #1094
Conversation
Tools, streaming, and audio/image/video no longer eject orchestrator/free into sticky single-agent passthrough. Failed workers are re-selected on the control plane. Responses streams paper-role output as OpenAI reasoning_text events; Chat Completions and media endpoints return only the modality result. Incident: ContextualWisdomLab/.github run 34079284863 job 101622944649 step 23.

Registering that one KV credential discovers both OpenCode catalogs as separate provider accounts. The dual-catalog test patches _fetch_json by URL so Models.dev prefetch stays offline.

A tools payload on orchestrator/free stays on Fugu route, and a provider tool_calls message is framed instead of rejected as empty content. Two-argument conduct progress hooks keep working.

Thinker, verifier, and synthesizer no longer inherit the request tools array. Conduct progress redacts step text before streaming reasoning events. The OpenCode dual-catalog test patches get_credential instead of writing the process KV.

The virtual-route worker You are interacting with an AI system. |
Pre-byte ToolFallbackStoppedError stays terminal instead of hopping to the next worker. A successful stream resets the circuit. The OpenCode dual-catalog test now asserts the shared key is sent to both list URLs.
ThreadingHTTPServer serves every request on its own thread and a single TaskOrchestrator is shared across all of them, but the pending assistant extras carried from _invoke to route_once were plain instance state. A sibling request's _invoke resets that attribute on entry, so it could wipe another thread's tool_calls between that thread's write and its read. The caller then received content: null with no tool_calls and no error -- a silent wrong answer rather than a failure. ModelClient already keeps the same data in threading.local; this restores that protection at the orchestrator hop by backing the attribute with a per-thread value, leaving all four existing read/write sites unchanged. Verified: with a barrier holding each thread between the write and the read (timing only, no logic changed), the unfixed tree drops tool_calls for 24 of 48 concurrent callers and the fixed tree drops none. Full suite 3408 passed, 2 skipped; interrogate 100%. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

The tools gate added here matches the three virtual selectors exactly, and _validate_chat_model applies only .strip() and a length check -- no provider prefix stripping, no case folding. Nothing asserted that, so a later "helpful" normalization could widen the gate silently and route ids the caller never asked for into single-agent passthrough. Measured against a live test server rather than read from source, because a source reading of this gate predicts the opposite outcome: orchestrator/free 200 route ' orchestrator/free ' 200 route (.strip()) openai/orchestrator/free 400 invalid_model openai/contextual-orchestrator 400 invalid_model ORCHESTRATOR/FREE 400 invalid_model The alias is refused before it can reach named_tool_passthrough, so this is fail-closed rather than silent degradation. Mutation control: injecting a provider-prefix + case normalization into _validate_chat_model turns the first alias into (200, 'route') and fails this test.

OpenCode Review Overview
Coverage evidence did not pass, so approval is blocked. The formal pull-request review is the source-backed diff review, not this status comment. |
CI-seeded OPENCODE_ZEN_API_KEY was registered for discovery but dropped by G∩P∩R: default bootstrap skipped the optional credential, and P excluded it, so honest-free Zen/Go rows never entered orchestrator/free. Noema then 429'd on OpenRouter with one caller attempt. Keep OPENAI_API_KEY out of P.

Summary
Virtual selectors (
orchestrator/free,orchestrator/auto,contextual-orchestrator) stay on the Fugu route / TRINITY–Conductor control plane for every inference surface. A tools array,stream=true, a non-text modality, or a structuredresponse_formatno longer ejects those requests into sticky single-agent passthrough.This PR now covers two consumer paths that used to look similar and are not:
proxy_completion(single_agent=True)and return500 internal_error.response_format— issue #1045 comment. Inkspan Noema job 101628090366 against base414f2297sent onlymodel,response_format, andmessages(no tools, no stream), then HTTP 502 after 1651.7s ondeepseek-ai/deepseek-v4-flash-0731with caller attempts=1 and preflightready_count=7. That path was structured conduct synthesis, which previously advanced a virtual synthesizer only after HTTP 413.Behavior

Concrete model pins stay sticky. Exhaustion is a typed receipt, not an unclassified 500. Default model timeout remains unset. No paid fallback.

Predecessor-head run34217041801was GREEN: 3422 tests passed with 2 skipped; the focused NIM suite passed 134 tests with 1205/1205 statements and 436/436 branches, public-doc coverage 100%, wheel build/install/import, SBOM, supply-chain, CodeQL and fuzz lanes all passed. It is retained as history only and is not exact-head evidence.Review RED→GREEN on 2026-09-08 for the four later findings: targeted regressions first produced 5 failures, then all 5 passed after the minimal fixes. The broader related suite passes 107 tests. Five-field race outcomes now retain provider usage in both audit and cost ledgers; successful capability calls clear prior circuit failures on both return paths;
orchestrator/autohas an explicit exact-match model-id contract; and structured synthesis preserves terminal tool-stop as typed HTTP 409 without candidate replay or message leakage. The four inline threads are resolved. Predecessor-head Security and Quality34232412314is terminal GREEN: 3427 passed and 2 skipped; its focused NIM suite passed 134 tests with 100% measured coverage and 100% public-doc coverage. Security Scan34232412418, SAST Semgrep34232412487, supply-chain/SBOM, and fuzz are GREEN. CodeQL PR34232412328dispatched all three language shards successfully; each current job recordsVERDICT_STATE=pending, so central authenticated terminal verdicts remain a merge gate.Latest review repair: five reproduced failures now pass. Worker tool calls terminate route/conduct before text judging or later roles, retain the normal conduct persistence path, and stream with required indices. Progress callbacks accept keyword-only output and keyword rest parameters. Concurrent request tests fail on worker exceptions and unfinished threads. Nine focused suites pass 125 tests; lint adds no findings relative to the prior head (32 existing findings remain). The production delta covers 23/23 executable changed lines and 14/14 branches originating on changed lines; this is not full-function or full-module coverage. Live-provider behavior remains unverified. The linked tool fallback runbook records reproduction and release boundaries; its final GitHub rendering was visually checked after wrapping the command.
Current-head review RED→GREEN on 2026-09-08: the two new CodeRabbit findings reproduced as 2 focused failures. A shared race-result usage extractor now preserves the fourth-field usage of tool-call race losers through local batch retrieval and its cost ledger. Chat Completions and Responses now forward the normalized
tool_choicevalue and omit empty controls. The focused regressions pass, and the broader cost-routing and tool-choice suite passes 119 tests.

The Inkspan job is pre-fix evidence on base
414f2297. GREEN for #1045 still needs the same consumer review against a released immutable owner version of this head. Handshake Errors on this PR remain chicken-and-egg until that pin exists; they are the work item, not a reason to skip org review.Merge
Independent review required. No self-approve, no force-push.
