fix(sidecar): give the gateway preflight probe a real reasoning budget - #1436
Conversation
Exact-evidence root cause (downloaded strix-reports artifact from PR #912's run 33304076516): the routing probe already selects deepseek-ai/deepseek-v4-flash-0731 (nvidia_nim) as 'ready' using the launcher's own REVIEW_MAX_OUTPUT_TOKENS=4096 budget, but this script's separate end-to-end gateway check re-tests the exact same route through 'orchestrator/free' with only max_tokens=16. A reasoning model spends part of that budget on internal reasoning before any answer content, so it returns a 'reasoning' field with no usable content; contextual_orchestrator.orchestrator._response_content correctly raises ProviderResponseError for that, which server.py's generic handler maps to 502 'invalid_structured_output' -- a healthy model gets misreported as completely broken, and every PR's opencode-review/noema-review/strix has been failing at sidecar boot for this reason, not a real review or security finding. Match the working probe's budget so the gateway check doesn't retest with a stricter constraint than the routing decision it is meant to confirm.

Sorry, something went wrong.
…ests Per owner review on PR #1436: source correctness alone doesn't establish operational acceptance without a test-first contract. - test_gateway_preflight_max_tokens_is_synchronized_with_the_routing_probe: asserts the bash script's gateway_preflight_request max_tokens equals REVIEW_MAX_OUTPUT_TOKENS. Verified this fails RED against the pre-fix literal (16 != 4096, confirmed by temporarily swapping in origin/main's sidecar script and re-running just this test) and passes GREEN on the fixed script. - test_reasoning_without_content_remains_rejected_even_with_the_full_budget: negative control proving a genuinely reasoning-only/no-content response still fails the routing probe's fail-closed check at the full 4096-token budget -- the max_tokens fix widens the budget, it does not weaken the content check that must still reject a truly broken route. Also fixes Devin's finding: the sidecar comment cited a gap-baseline entry that did not exist yet. Named it exactly and pointed at the actual repo (contextual-orchestrator, where the strix-reports evidence trail lives) -- landing in a follow-up commit there.

…-pass Merging main into this branch picked up #1436, which independently fixes a different bug in the same sidecar script: the post-healthz gateway smoke request's max_tokens was desynchronized from REVIEW_MAX_OUTPUT_TOKENS, so a reasoning-capable route the launcher's own preflight had already proved ready could still exhaust its budget on internal reasoning before visible output, failing the separate smoke request with 502 invalid_structured_output. This is the precise mechanism behind the earlier PR #1433 "healthz reached, then 502" signature this doc described without yet knowing the cause -- a genuinely different bug from this session's own family-cap/stale-model finding, not a duplicate. Recorded so the two fixes aren't mistaken for redundant work. Co-Authored-By: Claude <noreply@anthropic.com>
…xqzc Reconciles this branch's evidence-gated Strix pool-gating work with three bypass-merged main commits that landed while this PR was under review (#1434: unconditional Strix free-only flip with the single-outage-domain risk explicitly accepted, plus a family_cap 4->8 mitigation and an NVIDIA ZDR citation strengthening; #1436/#1440/#1439: sidecar preflight max_tokens and gateway-timeout fixes, unrelated to pool selection). Per the exact-head governance review on this PR (quoted in docs/adr/0003's new Amendment): an administrator bypass merge -- even one made with the risk explicitly surfaced and consciously accepted -- is not, by itself, operational acceptance of the underlying approach once a real review happens. This merge keeps #1434's orthogonal mitigations (family_cap raise, ZDR citation) and #1436/#1440/#1439's sidecar fixes, but replaces #1434's unconditional STRIX_MODEL/CONTEXTUAL_ORCHESTRATOR_POOL flip to orchestrator/free with this branch's evidence-gated conditional (free_family_diversity >= 2), restores strix_quick_gate.sh's is_contextual_orchestrator_model acceptance of orchestrator/auto (which #1434 had narrowed to free-only, which would have misrouted Strix's own safe fallback), and fixes several silent regressions where git's line-level merge took main's since-superseded literal because this branch's own text happened to match the merge-base after its earlier revert (not real conflicts, so no marker -- caught by re-running the full test suite and grepping for every orchestrator/free vs orchestrator/auto assertion post-merge). Also implements, in response to a live root-cause investigation surfaced during this merge: a bounded (1-retry) probe in the launcher's own preflight loop (already committed pre-merge) and a new opt-in --require-minimum-serving-diversity runtime floor in contextual_orchestrator_review_launcher.py -- a defense-in-depth backstop, distinct from strix.yml's decision-time free_family_diversity gate, that refuses to serve() a post-preflight pool spanning fewer than 2 independent provider families. Off by default (not yet enabled for any caller, including Strix): analysis found today's documented single-family-dominated free-route catalog means enabling it unconditionally would make even the safe orchestrator/auto fallback refuse to boot, a worse availability regression than what this change exists to prevent.

…t timeout) Verified directly from #1441's noema-review job log (99249903390, head d877886): healthz and the launcher's own internal preflight succeeded (past the family-cap fix's stage entirely), but the shell script's separate post-healthz gateway smoke request -- max_tokens now 4096 per #1436's fix, up from 16 -- got zero bytes back for the full 120-second curl timeout. Distinct from both other evidence in this entry: not a bad-request rejection (no response at all) and not Strix's own client code path. Documented with plausible causes (the 120s ceiling never re-examined when max_tokens grew 256x; a real server-side hang for a specific request shape; transient flakiness) but not pursued further this pass -- noted as evidence for whoever picks this up next.

A fifth Devin Review pass found Trigger B's own definition too narrow: the ADR text described escalation as firing only on choices[0].finish_reason == "length", but the vendored ModelClient._response_content treats EITHER that OR a populated message.reasoning field with no string content as the same "budget too small" signature -- already anticipated in the codebase's own error message. This second condition is not optional: it is the exact original failure mode PR #1436 responded to, and a finish_reason-only predicate misses it entirely, since a reasoning model can exhaust its budget under a different or absent finish_reason and provider finish_reason semantics for this case aren't verified as uniform across a pool this heterogeneous. A finish_reason-only Trigger B would silently misclassify a genuinely healthy reasoning-capable candidate as down -- the same false-negative class this ADR's Trigger A/B split already exists to prevent, just resurfacing one level deeper. Widened Trigger B to the two-part OR-condition consistently through Decision SS1 (the trigger definition itself, both layers' handling) and SS3 (the escalation predicate prose, the worst-case arithmetic, and the "every other outcome" fallback case), plus the implementation-telemetry requirement (both finish_reason and the reasoning-without-content signal must be emitted). Layer 2's "no retry on Trigger B" now explicitly covers both signatures, not only finish_reason, since the same "already recorded as successful by the gateway's routing" reasoning applies equally to either. Matches this ADR's own round-5 finding, which the stacked implementation PR (#1452) already handles correctly in code -- this brings the design doc back in sync with it. Updated CHANGELOG.md and docs/product-technical-gap-baseline.md's repeated summaries to match. Verified against actual current file content (not assumed) before editing. 1897 tests pass (unchanged, docs-only), including this branch's own test-plan scope (test_pr_governance_audit_contract.py, test_product_technical_gap_baseline.py, test_contextual_orchestrator_review_sidecar_contract.py, test_strix_contextual_orchestrator_contract.py, test_pingora_edge_policy.py -- 105 passed, 1 subtest passed).
