…ption-first Claude chains One model id can now fail over across billing paths: an Anthropic OAuth subscription pool, Cursor's copy of the same model, then a pay-per-use Anthropic API key. - combo target `metered` + apiKeys[].allowMeteredComboTargets: issued keys never reach a pay-per-use target unless opted in; env token and loopback callers may. - anthropicAccountPool.quotaRecheckMs: caps a 429 account cooldown so a spent weekly window is re-offered instead of waiting days, and a recovered subscription serves again. - log a [combo] line naming the serving target index when a later target served.

Add a focused management API regression test for metered.
handleComboRoutes preserves a stored metered: true value when a PUT /api/combos target omits the property. An explicit metered: false must clear it.
Add the test near the existing management tests in tests/routing/combo-management-api.test.ts:
PUTa combo with a metered target.GETthe combo.- Remove
meteredfrom the returned target andPUTthe target list. - Assert that
GETstill reports the target as metered. PUTthe same target withmetered: falseand assert thatGETno longer reports it as metered.
The normalization assertions in tests/codex-integration/combos.test.ts do not exercise this management GET/PUT path.

Exclude denied metered targets from the replay-incompatibility check.
If an issued key cannot use a metered target, targetEligible excludes it from selection. onlyReplayIncompatibleTargetsRemain at Lines 456–465 still counts it. When every remaining unmetered target is replay-incompatible but a metered target is compatible, the no-pick branch returns comboUnavailable() instead of targetIncompatibleResponse(). Apply the same metered permission check when that helper builds remaining.

Summary
Lets one Claude model id fail over across three billing paths, in order, while clients keep sending the same id:
cursor/claude-opus-5-5, same effort),The ordering itself already works with a
failovercombo whosealiasis the id clients send. Configuring that alone left two gaps, which this PR closes:allowedModels: ["claude-opus-5-5"]would start spending pay-per-use credit the moment the subscription runs out. New combo target flagmetered: trueplusapiKeys[].allowMeteredComboTargets: issued keys stop at the last unmetered target and get its error, unless they opt in. The env token and loopback callers (the operator's own clients) are not restricted. Every pick, including the recovery picks, enforces it. The management combo route carriesmeteredacross GUI round-trips the same way it carrieslastResort.retry-after: 318747) cooled the account until that reset, so the chain stayed on Cursor or the API key even after the subscription recovered early. NewanthropicAccountPool.quotaRecheckMs(60000..86400000, unset = unchanged) caps a 429 account cooldown: the account is re-offered after at most that long, and it either serves again or answers 429 and is re-cooled. A combo request is not pinned, because every request starts at target docs: record OpenCode Go official contract retry #1. Account 403 backoff is unchanged.There is also one log line,
[combo] <id>: served by target #N <provider/model> (metered) after K earlier target(s), emitted when a later target served. It contains no account ids.Example:
