Reviewed as part of a bug-PR landing pass. Holding this one: the direction is right, but the implementation changes a routing/privacy boundary in a way that needs a design decision first, not just an approval. Two independent reviews reached the same conclusion from separate reads of the diff. The affinity fix does not cover the reported case. The router fallback picks a provider arbitrarily. src/router.ts:699-705 sends every bare
Two smaller things. The classifier detector What would unblock it: resolve affinity from the live routed model rather than static config; require an explicit provider binding (or a catalog match) before crossing to another Anthropic-adapter provider instead of taking the first enabled one; make For context: CI here is green but shows only policy/labeling checks, no exact-head test or typecheck job, so the test claims in the description are author attestations rather than CI evidence. |

Triage note (2026-08-15, maintainer): keeping as draft per the existing design hold. The Auto Mode classifier defect is real and unfixed on dev, but this implementation can silently move classifier traffic across providers (static config instead of live routed state, first-non-empty fallback, no model-support validation) — that crosses privacy, billing, and credential-routing boundaries. The design requirements from the earlier review stand: live routed state, explicit or catalog-validated provider crossing, actually-attempted fallbacks, narrowed classifier detection. |

When classifierModel or classifierFallbacks is configured, this prefix test classifies every ordinary bare Opus 4/5 request—including valid main-model IDs such as claude-opus-4-8, claude-opus-4-20250514, and claude-opus-5—as an Auto Mode safety check. wantsNativePassthrough() uses this resolver as its routed/native discriminator, so selecting one of those Opus models can unexpectedly disable native passthrough and send the user's main conversation to the classifier target. Identify classifier turns from their verified request shape/session context, or limit the match to a sentinel that cannot also denote a normal model.

For a configured list such as ["retired/claude-opus-5", "active/claude-opus-5"], this loop always returns the first nonblank string without checking whether its provider exists or is enabled; routing then throws for retired, and the valid second entry is never considered. Because the management API accepts such targets without provider validation, every list with an unavailable first entry behaves exactly like a one-element list. Resolve candidates against the active configuration, or pass the ordered candidates into the existing failover path so later entries can actually serve as fallbacks.

Restrict classifier matching to supported classifier identifiers.
Line 30 matches every ID that starts with claude-opus-4 or claude-opus-5. It therefore classifies unrelated IDs such as claude-opus-50 as Auto Mode classifier requests and rewrites them to classifierModel. Match only the supported Opus 4/5 classifier forms and their allowed dated variants.

The PR objective requires narrower classifier detection.

Attempt classifier fallbacks after a candidate fails.
Line 52 returns the first non-empty fallback before provider availability, model support, adapter compatibility, or upstream execution is known. A disabled provider, unsupported model, or failed first request therefore cannot advance to the next configured target. The current test only confirms first-entry selection.
Preserve modelMap precedence. Carry ordered classifier candidates into the routing/execution layer. Attempt the next configured target only after the preceding target fails. Return a classifier-specific error after all declared candidates fail.

The PR objective requires “actual ordered fallback attempts,” while the current implementation performs only first-value selection.

Reject classifier targets without a provider qualifier.
Line 1172 accepts classifierModel: "claude-opus-5". Line 1185 accepts the same value in classifierFallbacks. Line 1962 also preserves it during hand-authored config normalization. resolveInboundModel then returns the bare slug, so later routing can select defaultProvider. This restores the incompatible-provider and privacy-boundary failure that these settings must prevent.
Use one shared validator for API writes and persisted-config normalization. Require non-empty provider and model components after trimming. Reject invalid API input. Remove invalid hand-authored values. Add regressions for bare values such as "claude-opus-5" and malformed qualified values such as "RelayA/".

ocx config set claudeCode.classifierFallbacks '"Relay/model"' and ocx config import both pass through validateConfigCandidate, whose passthrough schema accepts this newly introduced field without checking its type; the command therefore reports success and persists the string, but the next config read reaches this normalization and silently deletes it. Keep tolerant normalization for hand-edited files, but add write-boundary validation for classifierFallbacks (and classifierModel) so CLI set/import reject malformed values instead of claiming to save settings that immediately disappear.

…ort classifierModel (lidge-jun#1697)
…rgets Auto Mode sends bare safety checks such as `claude-opus-5` with no provider, so they fall through to `defaultProvider` even when it does not speak Anthropic. This routes them to `claudeCode.classifierModel`, then the ordered `classifierFallbacks`, with `modelMap` still outranking both. Two mechanisms from the draft are deliberately removed rather than shipped: Affinity is no longer inferred from `claudeCode.model`. That value is the injected/default config slot, not the provider the live session actually selected, so it goes stale the moment the user changes the model picker -- and acting on it silently moves a classifier turn onto a provider with its own privacy and billing consequences. Real live-session affinity needs request and session state `resolveInboundModel` does not have; approximating it from static config is worse than not doing it. The router no longer falls back to "the first enabled provider whose adapter is anthropic". It picked by object insertion order and checked neither `models`, `selectedModels`, `disabledModels` nor discovery state, which is exactly the silent provider crossing lidge-jun#1697 asks us to avoid. The other half of that change IS kept: a disabled provider matching a known-model pattern is no longer selected. `classifierModel` and `classifierFallbacks` are operator-facing, so they get the surfaces that makes them usable: GET/PUT on `/api/claude-code` with the same trim/clear semantics as `model`, a fallback-array validator that rejects non-string entries instead of persisting them, docs-site coverage, and load-time normalization. That normalization also fixes an activation bug it would otherwise have inherited: `normalizePersistedClaudeCode` was reached only through a `subagentEffort` short-circuit, so a config whose only defect was elsewhere in `claudeCode` was never normalized at all. It now runs unconditionally; the specialized subagentEffort warning is untouched.

Align the classifier routing contract with the resolver
The public configuration interface says that an unset classifierModel triggers same-provider affinity and compatible Anthropic-adapter selection, but the final resolveInboundModel path deliberately performs neither and returns the bare model unless classifierFallbacks supplies a target. SDK or config consumers following this contract may omit an explicit route and send classifier traffic to an incompatible defaultProvider, reproducing the failure this change is intended to prevent; update the comment to describe the explicit-only behavior.
