 不改变已有正式意见，head 变化仍需新证据。本修复改变默认队列和 readiness
 分类，不放宽正文校验，也不授予撤回评审或合并权限。
 
+The default queue also avoids duplicating a submitted independent review. A
+complete, paginated GitHub history can establish `independent_review` when a
+non-author, non-bot account with `OWNER`, `MEMBER`, `COLLABORATOR` or `CONTRIBUTOR`
+association submitted `COMMENTED`, `APPROVED` or `CHANGES_REQUESTED` on the current
+head. These are formal review events, including inline-only reviews, not issue
+comments. The typed history owner uses each reviewer's latest submitted event;
+pending reviews do not erase prior activity, and dismissal retires that actor's
+coverage. Missing actor/association metadata, incomplete reads or a new head
+cannot establish coverage. The live provider rechecks head/base after history.
+
+Covered rows remain in inventory with the reviewer, review URL/state and exact
+head, a null action, null plan/template and no evidence commands. Read that
+record once and continue the queue; the contributor need not write this agent's
+bilingual format. This is work coverage, not a qualified approval or merge
+permission. Existing dissent, strict approval-body qualification, closeout,
+validation and merge-readiness gates remain. An explicit authorized
+`--fresh-audit-exact-head NUMBER@HEAD_OID` can request new evidence despite
+coverage. No reviewer-name whitelist, new configuration or automatic write is
+introduced.
+
+默认队列也跳过已有独立评审覆盖的重复全文审查：完整分页的 GitHub 记录证明，
+当前提交已由非作者、非机器人且身份为 OWNER、MEMBER、COLLABORATOR 或
+CONTRIBUTOR 的账号提交 COMMENTED、APPROVED 或 CHANGES_REQUESTED。这里指正式
+review（包括只有行内意见的评审），不包括普通 issue 评论。复用同一 TypeScript
+历史 owner，按每个评审者最近的已提交记录判断；待提交不会抹去旧记录，撤销只
+撤回该账号的覆盖。身份未知、来源不完整或换头时不跳过，读取后还须核对 head/base。
+载荷的 `independent_review` 给出评审者、原记录链接、状态和精确提交；该行仍在
+inventory，但不生成可执行计划或证据命令。第三方无需使用本 agent 的双语格式。
+跳过重复工作不授予批准或合并资格，不清除阻塞意见；原批准正文、closeout、验证
+和 merge-readiness 门保留。明确要求重新取证时，沿原精确头 fresh-audit 入口执行。
+不新增人名白名单、配置或自动外部写入。
+
 After a published exact-head `APPROVE` is read back, the capability-owned
 `review_execution_contract.approval_closeout` requires effective-review
 reconciliation. This also works for an existing approval without a duplicate audit:

 Receive pending current-session requests through `review_execution_contract.decision_procedure.establish_goal` before generic queue selection, including other agents sharing a GitHub account; task intake and claimed action authority are separate judgments. Resolve the selected requests with repeatable `--target-exact-head NUMBER@HEAD_OID`. Follow `scheduling_policy` and its ranked actionable `review_sequence`; explicit current-request PR selection may override ordering only, never `pull_requests[].review_action_kind` or exact-head idempotency. Generic `re-review`, `重新review`, and `复审` wording selects the named PR; it is not a force-refresh token. Todo/monitor prose may not select work.
 When `review_action_kind` is null, the row stays in `pull_requests` inventory but must not appear in `review_sequence`; its `review_plan` and `review_template` are null and `evidence_commands` is empty. Read the packet's actual no-action reason and read back the relevant lifecycle/draft state or conclusion once; null action does not imply an existing conclusion. If the caller is also the authorized author and its proposal is complete, mark Draft ready and read back its state and unchanged head, then regenerate the packet. Reserve Draft for unfinished author work with a concrete remaining implementation or integration step. Missing review or held CI/merge qualification does not require Draft. A reviewer alone has no authority to change another author's submission state or invent a review action. Run a fresh audit only when the user explicitly requests fresh evidence despite an existing conclusion, or supplies a concrete new concern; regenerate with `--fresh-audit-exact-head NUMBER@HEAD_OID`, then execute the complete current plan and never inherit the earlier approval. Fresh audit is not a Draft bypass. For every actionable PR:
 
+When the capability supplies `independent_review` and a null action, read back
+that submitted review and skip duplicate full review. Its source-bound coverage
+does not require this agent's bilingual body format, grant approval or merge
+authority, or clear blockers. Unknown provenance does not establish coverage.
+An explicitly authorized fresh audit uses the same exact-head override above.
+
 1. Record the packet's exact head, then follow `review_execution_contract.decision_procedure`:
    the current goal and `problem_context` delivery judgment first, including on re-review,
    then `evidence_commands` and repository-native validation.
