fix(oauth): repair proactive-failover policy boundaries (carry of #3502, 1/2) - #3561
Conversation
Carries the policy half of #3502 onto current dev, rebased, with docs rewritten on top of #3520 rather than replayed. 1. src/oauth/anthropic-routing.ts consulted the pool's proactive strategy even when the pool is disabled, so a disabled pool silently reactivated round-robin/fill-first on the reactive 429 path. Reactive recovery now uses the neutral quota picker there. 2. src/oauth/generic-account-failover.ts honoured only enabled === false per provider, so a provider-specific true could not opt back in when the global default is false. The published narrow-over-broad precedence now applies in both directions, and the typeof guard still lets a malformed value fall through rather than taking a provider out of service. The Kiro continuation half of #3502 is split into the next PR in the stack.

📝 WalkthroughWalkthroughThe change makes provider-specific OAuth failover overrides effective in both directions. It separates proactive account preference from reactive Anthropic 429 rotation, adds quota-based recovery for disabled pools, and adds coverage for generic OAuth and Anthropic sidecar flows. ChangesOAuth failover policy
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🔵 Low · up to OAuth failover behavior is covered, but provider documentation still suggests that disabling proactive preference prevents reactive 429 account rotation. Operators could configure the setting expecting to prevent rotation when it will still occur. Sequence Diagram(s)sequenceDiagram

Approved on exact head c2ba04a85357b8b3578733e7575c7dd69c73eb6a. The provider-level boolean now correctly overrides the global proactive preference in both directions while reactive 429 recovery remains presence-driven. Disabled Anthropic pooling no longer reactivates its dormant strategy; the retained quota-window scoring is consistent with the documented neutral quota-ordering recovery. Isolated focused verification passed 43/43, all exact-head cross-platform checks are green, and no unresolved thread remains. The CodeRabbit documentation concern is not reproducible: the English configuration reference and CLI/account docs explicitly state that enabled:false does not disable reactive 429 rotation.

Two OAuth failover policy defects from #3502, split from its Kiro half so the
src/oauth/security surface is reviewed on its own.src/oauth/anthropic-routing.ts: a disabled pool no longer applies its dormant proactive strategy to reactive recovery (it recovers viapickLowestUsage).src/oauth/generic-account-failover.ts: a per-providerenabled: truenow beats a globalfalsein both directions, with thetypeofguard preserved. Doc comments insrc/types/{config,provider}.ts, the Englishproviders.mdrow that claimed onlyfalsewas meaningful, and thestructure/04owner row are corrected.Carries #3502 (author @Ingwannu) onto current
dev; contributor hunks reapplied. Supersedes #3502 together with the 2/2 layer.Security boundary: touches
