 - `pool.minOwnerBalanceUsd`: pool key owner 最低余额，sync/validate 会补齐。
+- `pool.minOwnerConcurrency`: 统一消费 API key owner 的最低并发，sync/validate 会补齐；用于避免共享 key 在用户并发层触发 WS 1013，不要用提高某个 provider capacity 来掩盖。
 - `pool.defaultTempUnschedulable`: 默认账号级临时下线规则；用于在上游返回容量、限流、overload 或认证状态异常时，让 Sub2API 冷却该账号并切换到同组其他账号。
 - `profiles.entries`: 从 master `~/.codex/` 选择上游 profile 并映射到 Sub2API account。
 - `profiles.entries[].capacity`: 可选 per-account concurrency override；不写则使用 `pool.defaultAccountCapacity`。具体数值只以 `config/platform-infra/sub2api-codex-pool.yaml` 为准，skill 和长期参考只描述规则，不重复写当前值。
+- 除非用户明确要求修改配置，不要仅凭推断改账号 membership、priority、capacity、WebSocket mode 或其他调度策略；先保留 YAML，完成 provenance/runtime evidence 溯源，并把结论写回相关 issue 或 runbook 后再提出变更。
 - `profiles.entries[].tempUnschedulable`: 可选 per-account 临时下线规则覆盖；字段语义以 `docs/reference/platform-infra.md` 为权威。
 - `profiles.entries[].openaiResponsesWebSocketsV2Mode`: 需要 Responses WebSocket v2 的上游才设置，值为 `off`、`ctx_pool` 或 `passthrough`。
 - `profiles.entries[].upstreamUserAgent`: 少数要求 Codex CLI User-Agent 的上游才设置，不能含换行。

 - `pool.groupName` names the Sub2API group that represents the pool.
 - `pool.apiKeySecretName` and `pool.apiKeySecretKey` name the k3s Secret that stores the single consumer API key.
+- `pool.minOwnerConcurrency` declares the minimum concurrency for the Sub2API user that owns the unified consumer API key. Keep it high enough to cover the declared account capacity set, so the shared key does not fail WS sessions at the user-concurrency layer. Do not compensate for owner-concurrency 1013 errors by pinning capacity to one provider.
 - `pool.defaultTempUnschedulable` declares Sub2API account-level temporary unschedulable rules. Keep 429/overload/capacity failures in this YAML policy so the scheduler can cool down a failing account and choose another candidate instead of hard-pinning one provider.
 - `profiles.entries` selects local Codex profile files from `~/.codex/` and maps them to Sub2API account names.
 - `profiles.entries[].capacity` optionally overrides `pool.defaultAccountCapacity` for one account. Capacity is a YAML-controlled routing input; concrete current values belong only in `config/platform-infra/sub2api-codex-pool.yaml` and runtime validation output, not in long-term reference prose. Code constants, Secrets, ad-hoc runtime patches, or stale tests must not override YAML source of truth.
+- Do not change account membership, priority, capacity, WebSocket mode, or other routing policy from inference alone. Unless the user explicitly asks for a configuration change, first preserve the current YAML, collect provenance and runtime evidence, and write the finding to the relevant issue or runbook before proposing a change.
 - `profiles.entries[].tempUnschedulable` may override the pool default for one account. The CLI renders it into Sub2API credentials as `temp_unschedulable_enabled` and `temp_unschedulable_rules`; rules match HTTP status plus response-body keywords and place only that account into a temporary unschedulable cooldown.
 - `profiles.entries[].openaiResponsesWebSocketsV2Mode` is the account-level Responses WebSocket v2 switch for OpenAI-compatible upstreams that require WebSocket transport. Allowed values are `off`, `ctx_pool`, and `passthrough`; omit the field unless that upstream needs it.
 - `profiles.entries[].upstreamUserAgent` is an optional account-level upstream request User-Agent override. Use it only for upstreams that require a Codex CLI compatible User-Agent; keep the value YAML-controlled and newline-free.
