Merge Risk: 🔵 Low · up to Routing can lose session stickiness after an unsuccessful cross-model selection, and malformed stored routes can appear in pool-settings responses. These bounded issues warrant owner awareness; the previously identified fallback-order problem has been addressed. Security Architecture ReviewSecurity architecture risk: 🔵 Low · up to The new routing policy is limited to an opt-in account pool, and the reviewed selection and retry paths apply its account restrictions.

A route name is an operator label and may resemble an account ID, so the local 401/429 answer for an empty or cooled route now uses a generic message. The proxy log keeps route:<name>.

Review comments at @src/oauth/anthropic-routing.ts:
- Line 584: Update cooldown classification in resolveAnthropicAccountForSession
to derive the candidate set from the effective routed or fallback pool before
filtering cooled accounts, excluding needsReauth and unusable accounts. Reuse
that same set for the all-cooled check and getAnthropicPoolRetryAfterSeconds so
the earliest applicable cooldown produces 429 with Retry-After; add regression
cases for a mixed route and an absent-ID fallback.
- Line 610: Update the affinity check around
eligible.includes(affined.accountId) so route-scoped ineligibility does not
delete a globally usable affinity: retain the affinity when
getEligibleAnthropicAccounts(now) includes its account, and delete it only when
that global eligibility check fails. Preserve the existing return behavior for
accounts eligible on the current route.
Review comments at @src/oauth/pool-settings-capability.ts:
- Line 179: Validate `anthropicAccountPool.routes` before projecting it as
`AnthropicModelRoute[] | null` in the pool-settings capability and the legacy
GET handler. If validation fails, return the existing invalid-configuration
error representation instead of passing through the malformed value.
Review comments at @tests/adapters/anthropic/anthropic-model-routes.test.ts:
- Around line 133-143: Add a continuation regression case alongside the existing
routed 429 test: configure a model route, make its first account return 429, and
assert continuation retries a routed sibling rather than the eligible outsider.
Use the existing test helpers such as seed, config, and post, and verify the
continuation response and sends.
- Around line 133-143: Add a routed sidecar 429 regression test alongside the
existing Anthropic route tests: enable an account pool route containing accounts
1 and 2, make account 1 return 429, and verify the retry succeeds through
account 2 without sending to outsider account 0. Exercise the production sidecar
failover path so the test detects loss of route enforcement in its on429 hook.

Retain a globally usable affinity after an out-of-route failure.
eligible is route-scoped. If affinity points to A and the current route contains only B, this branch can delete A. If B admission fails, the next unmatched-model request can rerun active, strategy, or quota selection instead of using affinity. It may select A again, so the practical impact is a minor loss of session stickiness, not a major request failure.
Retain A when getEligibleAnthropicAccounts(now) still considers it usable. Delete the affinity only when that check fails.
Suggested fix
- const stillThere = set.accounts.some(a => a.id === affined.accountId && a.needsReauth !== true);
- if (stillThere && eligible.includes(affined.accountId)) {
+ const globallyEligible = getEligibleAnthropicAccounts(now);
+ if (eligible.includes(affined.accountId)) {
return { accountId: affined.accountId, reason: "affinity", routeName: decision?.name };
}
- sessionAffinity.delete(key);
+ if (!globallyEligible.includes(affined.accountId)) {
+ sessionAffinity.delete(key);
+ }Add a cross-model regression test for failed B admission followed by an unmatched-model request.

If anthropicAccountPool.routes contains a malformed non-array value, src/config/schema/config-schema.ts preserves it during configuration loading. Both src/oauth/pool-settings-capability.ts:179 and the legacy GET in src/server/management/oauth-account-routes.ts:662 then return that value through fields typed as AnthropicModelRoute[] | null.
Parse or validate routes before both projections. If validation fails, return the existing invalid-configuration error representation instead of returning the malformed value as a route array.

Summary
The opt-in Anthropic OAuth account pool picked accounts without knowing the requested model (#5561). A subscription tier without access to a model could be chosen, fail upstream, and be picked again. Operators can now declare model routes:
matchglob (*/?, full string, case-sensitive, linear-time matching; routes are ordered and the first match wins; names and patterns are unique, at most 32 routes of 32 accounts). A matched route limits every pick to its accounts: quota, round-robin, sticky, fill-first (declared order), manual/active preference and session affinity. An affined account outside the route loses priority and is not rebound. Unmatched models keep today's behavior, and so does a disabled pool.authentication_error, or 429 with a route-scopedRetry-Afterwhen all route accounts are cooling. The client message is generic ("this model route"); the route name, an operator label that may resemble an account id, appears in neither the client response nor the log; the log names the rule by position."fallback": trueon a route lets an empty route use the whole pool; it never widens while an in-route account is eligible. When that expanded pool is all cooling, the answer is 429 with the earliest expanded-poolRetry-After, even if the route names a removed account.route:#<n>(the rule's 1-based position) after a committed choice. The configured route name is never logged, because an operator may name a route after an account id. Neither the credential nor the raw account id is logged./api/oauth/accounts/pooland/api/pool/settingsread, validate, replace, preserve (on unrelated strategy/sticky updates) and clear them (null). Other pool kinds rejectroutes. Malformed routes are rejected on write.
