feat: side-thread task kind (Muse role alignment phase 2)

Tasks gain kind='main'|'side' (NULL=main). A side thread hangs under a
parent task, defaults to the local executor, never builds a worktree,
branch or container unless explicitly asked, and writes its conclusion
back to the parent via task_followups on terminal transition.

- server: kind validation + side-thread gates (parent required, no
  coordinator_parts/upload_id/environment_id, parent must not be a
  coordinator), local executor default, GET /tasks kind filter,
  /worktree 404 and /fork /merge /pr 409 for side threads.
- worker: side-default shunt in _run_attempt (no-worktree scratch cwd,
  in-memory plan=1 when a repo is present, seed/checkpoint skipped),
  _writeback_side_thread, marker task-create kind field + inheritance,
  side threads excluded from marker spawn counts.
- host/sandbox: --no-worktree plumbing for dispatch/goal/popen
  (Local + Docker), scratch cwd work/side-threads/<task-id>.
- console (classic only): kind filter + [旁聊] rows + '开旁聊' entry,
  side-thread dispatch mode, side-thread list in detail, merge/PR/fork
  hidden for side threads; build exit 0, console.html sha df39db5a.
- tests: new test_sidethread.py (29 tests) + kind backfill tests in
  test_p2_migrations.py; full cloud suite 3900 tests OK (skipped=13).

+"""Declarative agent definitions (harness alignment, v1).
+
+Zero third-party dependencies; standard library only.
+
+A definition is a versioned JSON document that bundles the fields a
+task already understands -- model, effort, approval, executor, plan --
+plus a human-written instruction block and a list of required skills.
+It is the Foundry-style "agent defined declaratively, harness runs
+the loop" idea, cut down to what this codebase can actually honour
+today, with every boundary written down instead of implied:
+
+* Resolution happens at task creation (``POST /tasks`` with an inline
+  ``agent`` object). Per field, an explicit body field wins over the
+  definition; a field absent from both stays NULL and follows the
+  existing worker-default chain. A definition that sets ``model``
+  therefore makes the task explicit for rule routing v0, and a
+  definition that leaves ``model`` empty leaves routing to the worker.
+* Instructions reach the model only as a marked header prepended to
+  the stored prompt (``[Agent: <name>]``), because the dispatch path
+  (``cloud/sandbox.py`` -> ``host.py dispatch``) has no
+  developerInstructions channel today. This is NOT claimed to be
+  ``developerInstructions``: it is visible in the stored prompt, in
+  the creation response, and in every later prompt read. Instructions
+  are rejected with goal tasks and coordinator tasks, where the
+  prompt is a goal or is never run as a model turn, so the header
+  cannot silently pollute a goal text or a coordinator parent.
+* Skills are validated against the ``cloud/skills/`` pack at parse
+  time (an unknown skill is a 400, never a silent drop). Seeding
+  itself stays worker-global (``--seed-skills`` seeds the whole pack
+  into the tenant codex-home); v1 does NOT claim per-agent seeding.
+  When seeding is off, a listed skill is recorded in the creation
+  response but is not guaranteed present at run time -- that is the
+  documented v1 boundary, not a bug to be discovered later.
+* Routing policy is deliberately NOT part of a definition in v1:
+  routing stays a worker-global policy (see ``cloud/models.py``).
+  Putting a routing object inside a definition would either be
+  silently dropped (a lie) or need a per-task policy column that does
+  not exist. A definition that contains ``routing`` / ``routing_policy``
+  is rejected, so a typo or a v2 idea cannot masquerade as v1 behaviour.
+* Unknown top-level or defaults keys are rejected for the same
+  reason: a declarative file must fail on typos, not silently ignore
+  them.
+
+v2 (this file, plus server/worker/sandbox/host changes) closes the
+three v1 boundaries that were explicitly left open:
+
+* Registry: definitions can live as files under repo-root ``agents/``
+  (``default_agents_dir()``) and be referenced by name
+  (``agent_name``) instead of only inline. The server never loads a
+  definition from a caller-supplied path; it only loads
+  ``<name>.json`` under the registry dir, with the traversal guard
+  in ``load_agent_definition``.
+* Persistence: ``tasks`` gains ``agent_name`` / ``agent_version`` /
+  ``agent_instructions`` columns (see ``migrate_tasks_table``), so
+  ``GET /tasks`` shows the definition identity and instructions, and
+  the worker no longer has to reconstruct them from a prompt header.
+* Real channel: for local/docker executors, instructions travel as
+  ``--developer-instructions`` on the host.py top-level command,
+  through ``sandbox`` into ``host.py dispatch`` ->
+  ``create_thread(developerInstructions=...)``. The stored prompt
+  stays clean. For the generic cloud executor, which has no such
+  channel, the worker falls back to the v1 marked header in the
+  in-memory dispatch prompt only (DB prompt stays clean) -- that
+  fallback is the documented cloud boundary, not a claim that the
+  cloud runner honours developerInstructions. Goal and coordinator
+  tasks still reject instructions in v2: the goal loop and the
+  coordinator parent do not pass instructions through, and silently
+  dropping them there would be worse than rejecting them.
+
+v3 (tools, this file plus server/worker changes) adds a ``tools``
+field, but deliberately as REQUIRED tools, not an allowlist:
+
+* A definition may declare ``tools`` from the MCP servers this
+  codebase actually seeds: ``websearch``, ``imagegen``,
+  ``playwright``. An unknown tool is a 400, never a silent drop.
+* The worker does NOT claim to block other tools. Blocking would
+  need a tool allowlist in ``create_thread`` (which does not exist)
+  or per-task codex-homes (tenant homes are per-project and shared,
+  and MCP seeding is worker-global), so an allowlist claim would be
+  false. What v3 does instead is fail fast on the opposite, silent
+  failure: a task that declares a required tool but whose tenant
+  codex-home config.toml has no ``[mcp_servers.<tool>]`` section
+  at dispatch time is marked failed before any model call, with the
+  missing tools named. The check runs only for tenant-isolated
+  Docker workers, where the tenant config.toml is the actual
+  availability record (worker flags alone would be wrong: a section
+  seeded earlier by another worker persists in the shared tenant
+  home). Local/cloud workers skip the check and are documented as
+  such, not as "tools verified".
+
+v9 (tool approvals, this file plus server/worker changes) adds a
+``tool_approvals`` field, and it is deliberately narrower than
+"per-tool approval enforcement" -- the execution layer cannot
+honour that today, and this track says so instead of claiming it:
+
+* Declaration: ``tool_approvals`` maps a known tool to one of
+  ``ask`` / ``auto`` / ``deny``. Unknown tools and unknown
+  policies are 400s. A tool declared both required (``tools``)
+  and ``deny`` is a 400: a task that must use a tool it must
+  never be allowed to use is a contradiction, not a policy.
+* What is NOT claimed: per-tool interception in host.py.
+  ``host.py _answer_server_request`` answers every elicitation
+  with one global switch (``approval == "auto"`` accepts,
+  anything else declines) and the elicitation message carries
+  no tool/server identity this codebase can rely on, so host
+  cannot tell which tool is asking. The approvals queue
+  (``cloud/approvals.py``) is record-only today: host runs in
+  a worker-spawned subprocess with no control-plane channel,
+  so there is no "ask the user" path at runtime. Credential
+  scope is NOT part of this field either: MCP credentials live
+  in the tenant codex-home config / env, per-project, not
+  per-task, and declaring a scope here without a channel to
+  enforce it would be the same kind of lie.
+* What IS executed: the declaration is validated at creation,
+  persisted (tasks.agent_tool_approvals, JSON object, NULL =
+  undeclared), echoed in GET and the creation response, and
+  at dispatch the worker audits the declaration together with
+  its effective outcome under today's host behaviour
+  (``effective_tool_approvals``): ``auto`` + host-auto accepts,
+  everything else declines, and ``ask`` is reported as
+  "decline (no ask channel)" -- never as "will ask". The
+  worker also re-checks the required+deny contradiction at
+  dispatch (defence in depth for rows written before v9 or
+  outside the API) and fails fast before any model call, in
+  the v3 tools-gate shape. Goal and coordinator tasks reject
+  tool_approvals at creation, like instructions: their turns
+  do not pass the declaration through, so accepting it there
+  would be a silent drop.

+  fields. ``aggregate_attempts`` counts ONLY ledger rows: a
+  resume row (outcome NULL) is skipped, never counted as a
+  defect-free first pass -- otherwise a task that was merely
+  auto-resumed would silently gain a counted attempt.
+- The one deliberate relaxation: ``outcome`` is nullable in the
+  unified DDL even though the ledger writer always supplies it.
+  A ``NOT NULL`` on ``outcome`` would make the resume writer's
+  insert (which has no outcome to report) fail on a fresh table,
+  so the constraint lives in Python validation here, not in the

+
+已有的、不在本轨重复造的机制（查代码确认）：
+- 任务创建幂等：tasks 的 UNIQUE(project_id, idempotency_key)，
+  重复创建回读已有任务，并发抢建靠 IntegrityError 回读。
+- goal 断点：task_checkpoints 每轮快照（worker 镜像线程 +
+  终局导入），goal 任务自动续跑走同一线程、同一 worktree、
+  从 goal_rounds_done 下一轮起；无进展熔断（断点轮次 3 次
+  不变即 stall）与退避、次数上限并存。
+- 合并与通知的 CAS：终局写回只在 running 时成功才写结果、
+  记成本、发通知，重复终局不重复记账发通知；协调员子任
+  务按分工名复用，不重复建。
+
+本轨补的缺口，恰恰是上述机制都没盖住的那一段：非 goal
+任务被平台中断后，auto_resume_interrupted 会把它全新重
+排——同一 worktree 里文件还在，但重排前会清掉 result_text /
+error_text / interrupted_reason，新一轮 agent 只拿到原始
+prompt，既不知道上一尝试做到哪一步、出了什么错，也无法
+区分“worktree 里已有的文件是上一尝试的产物还是仓库原有
+内容”，于是可能重复创建上一尝试已创建的东西。goal 任务
+不受此影响（线程连续性自带历史），协调员子任务也不受此
+影响（auto_resume 本来就不接 coordinator_orphan）。
+
+本轨只做三件可执行的事，全部在 worker/server 层，不改
+host.py、不改 codex 线程恢复：
+① 尝试账本 task_attempts：auto_resume 把任务回 queued
+  之前，先把正结束的这次尝试记下来——attempt_no（= 旧
+  auto_resume_count + 1，即正结束尝试的序号）、kind
+  （goal_breakpoint 或 platform_fresh）、interrupted_reason、
+  checkpoint_round（库中断点最大轮次，非 goal 恒为 -1）、
+  result_text / error_text 各截断 2000 字。记账与回 queued
+  在同一事务里，记账失败不单独炸恢复循环（外层已兜底），
+  但同一 (task_id, attempt_no) 重复记时 INSERT OR IGNORE
+  保留第一次，不覆盖。表定义是统一 schema（FLAG-1，
+  2026-11-05）：本模块不自带一份 DDL，CREATE_TABLE_SQL
+  与建表/迁移均取自 ``cloud.attempt_ledger`` 的
+  ``TASK_ATTEMPTS_DDL`` / ``ensure_task_attempts_table``，
+  与台账写路径共用同一定义；本模块写的行 outcome 为
+  NULL（恢复历史行，非台账计数行，见 attempt_ledger 对
+  aggregate 的口径）。
+② 重跑前言：非 goal 平台全新重排的任务在认领时，worker
+  在内存副本的 prompt 前贴一段上次尝试说明（原 prompt
+  不落库，与项目/待办/记忆注入同款只改内存副本），内容
+  是账本里的事实——第几次尝试、中断原因、断点轮次、上一
+  尝试部分输出与错误（各截断 1000 字）——并明确要求先查
+  worktree 现状再动手、对 worktree 外的产物先核查再创建。
+  goal 断点续跑、_resume 任务、协调员任务一律跳过（它们
+  已有会话连续性或不跑模型回合）；账本里查不到记录的老
+  任务原样返回，不编造。
+③ 时间线读回：GET /tasks/{id}/timeline 在 steps /
+  checkpoints 之外加 attempts 数组，项目 read 权限复用
+  时间线原有校验，只读不改。
+
+诚实边界（写进模块与交付，不宣称）：
+- 前言是指令不是保证：agent 仍可能重复创建，账本只能
+  降低重复概率，不能像创建幂等键、合并 CAS 那样硬保证
+  不重复。worktree 外的产物（分支、PR、发布等）账本不
+  追踪——它只记 DB 里已有的事实，不读 worktree、不调外
+  部 API；那些产物的硬去重仍靠各自已有的门（创建幂等键、
+  合并状态 CAS、分工名复用）。
+- 本轨不做 worktree 文件快照：快照路径因执行器而异
+  （local / Docker 租户 / cloud 的 worktree 位置不同），
+  在 worker 层硬做快照会把执行器差异漏进账本；agent 在
+  本轮里自己查 worktree 现状是更可靠的口径。
+- 手动重试（/retry、/continue 等）不经过 auto_resume，
+  故不记尝试账本、不贴前言——用户显式重试时由用户自己
+  在新消息里给上下文，本轨不替用户编造上一尝试说明。

+"""有界自动审计循环（audit loop），只对确定性门做自动循环。
+
+设计前提（先核实再动手，见模块末尾的“复用清单”）：
+生产代码里没有“审计员 agent”，所以这里的“审”只能是确定性
+检查的结果——测试/校验命令、能力门、干跑阻塞、迁移列、格式
+等可客观判定对错的门。主观审计（架构、设计、代码美观）绝不
+触发自动循环，只返回 needs_review，走人工。
+
+有界方案（用户已定，一字不差地落地）：
+1. 只对确定性门循环：Finding.kind 只能是 deterministic 或
+   subjective；subjective 一律 needs_review，不推回、不计轮。
+2. 推回包写死：每条 Finding 必须带 id、evidence、reproduction、
+   acceptance，四者缺一即 ValueError（调用方 bug，不进循环）；
+   PushbackPacket 带 round、findings、criteria（本轮结束后仍未
+   解决的验收标准，finding_id -> gate_or_None）。
+3. 上限 3 轮：round = 已发出的推回数；round < 3 且有 finding 才
+   推回，round >= 3 且仍有 finding 即升级（escalate），不再循环。
+4. 重审审全量：每轮必须重跑全部门；上一轮通过的门本轮未跑
+   即 gate_missing 升级；上一轮通过的门本轮变失败即 regression
+   finding，同样不得放行。
+5. 标准不得弱化：上一轮的 finding 只有在三种情况下才算解决——
+   本轮仍被报告（仍在解决中）、调用方以 fixed 传入已修复证据、
+   其关联 gate 本轮通过；否则该 finding 被丢掉即 standards_weakened
+   升级，绝不默许把标准越放越宽。
+6. 默认关闭：引擎只由 Worker.audit_loop_evaluate 显式调用，且仅当
+   任务字典含 audit_loop 真值时才启用；没有 env 开关——全局 env
+   会让所有任务悄悄启用循环，这是本设计刻意拒绝的。开关关闭时
+   run_one、auto_resume、协调员、goal 断点行为逐字节不变（本模块
+   不改 run_one，见 Worker 方法的文档）。
+7. 轮次持久化：状态存在 task_audit_loop_state 单行表（task_id 主键），
+   跨 worker 重启不丢；计数缺失或损坏时 fail-closed 到升级，绝不
+   默认循环。审计行（audit_log）是 best-effort，写失败会丢计数，
+   所以轮次绝不以审计行计数为准——这是不用审计行做持久化的原因。
+
+复用清单（核实结论）：
+- goal 的 verify_command：goal 任务已有的确定性校验门，本引擎
+  不重复造校验，只消费“门的结果”（gate_results）。
+- task_attempts 尝试账本：本引擎不复用它做轮次持久化，原因
+  是它的主键是 (task_id, attempt_no)，与 goal/platform 尝试共用
+  attempt_no 序号——audit_loop 若也用 attempt_no 记轮次，序号会
+  与已有尝试撞主键、被 INSERT OR IGNORE 静默丢掉，轮次就丢了。
+  因此按 attempts 的 DDL 手法（模块内 CREATE_TABLE_SQL +
+  ensure + db.py POSTGRES_SCHEMA + migrations 表清单 + server
+  初始化调用）另起单行表，序号冲突问题不存在。
+- task_followups：特意不复用——它是用户消息（用户含任务间互发），
+  把机器推回包写进 followups 会把机器包暴露给用户、混淆用户消息。
+  推回包由调用方持有（返回的 packet dict），不落 followups。
+- 协调员重排（UPDATE tasks SET status='queued' 带状态 CAS）：
+  调用方若要重排，用同一手法；本引擎本身不改任务状态、不重排、
+  不调 runner——状态变更属于调用方，引擎只给决策。
+- worker 的 fail-fast 门（能力门、工具门等）：本引擎不替代它们，
+  只在它们已经判定出的结果之上做“循环还是升级”的决策。

+# relay-config.json — mock 现状与接真实 relay
+
+`relay-config.json` 保持 UI 栈自带的 Bumian 配置原样，未换 provider、未写任何密钥值。
+
+## 当前状态：模型调用走本地 mock
+
+- `baseUrl` 是 `http://127.0.0.1:8095/mockrelay/v1`：app-server 的模型请求由本机 `host/mock-model.mjs` 用确定性替身回答，不出本机、不产生真实调用、不花钱。
+- `relayBaseUrl`（`https://www.bumianapi.top/v1`）只写在 JSON 里，host 代码没有引用它，当前不生效。
+- `apiKey` 为空字符串：真实 relay 需要 key 时，key 值绝不写进本文件。
+
+## 接真实 relay：两步
+
+1. 把 `baseUrl` 的值改为 `relayBaseUrl` 的值（即 `https://www.bumianapi.top/v1`）。
+   只改这一处；`providerId` / `providerName` / `model` / `wireApi` / `envKey` 不动。
+2. 在启动 UI host 的环境里设置 `BUMIAN_API_KEY` 环境变量（key 值只进环境，不进文件、不进仓库）：
+   `BUMIAN_API_KEY=<你的 key> scripts/run-codex-ui.sh`
+
+改完后 app-server 启动时按 `relay-config.json` 的 `-c` 覆盖走真实 relay；`chatgptBaseUrl`
+仍指向本机 `/mock`，插件目录、账号端点、遥测等 ChatGPT 后端调用继续由本地替身回答。

+- 有界委派（v5，Foundry“有界 subagent 委派”的对应物）：
+  每个分工除 name/prompt/model/effort/executor 外，还可带
+  三个显式边界，全部在 validate_parts 校验、经 DB 的
+  coordinator_parts JSON 原样流转、由 worker 的协调员循环
+  真正执行，不是只写进 prompt 的愿望：
+  ① timeout_seconds：该分工单次委派的墙钟上限，从协调员
+  本轮开始计时，超时由协调员循环直接 cancel 该子任务
+  （与全局超时同款 cancel 机制），其他分工继续等，不因
+  一个慢分工拖住整批到全局超时；② on_failure：fail（默认，
+  旧行为，任一非容忍分工未完成则协调员失败）或 tolerate
+  （该分工失败不拖垮协调员，汇总里点名已容忍，协调员
+  重跑时其 failed 子任务不再重排、interrupted 的仍重排，
+  因为后者可能是父任务取消所致、未获公平一轮）；③
+  result_chars：回传给父任务的单项输出上限，默认 500，
+  汇总报告本身仍受 worker 写回的 4000 字上限约束。
+  三个边界的执行点都在协调员层：超时在循环里 cancel，
+  容忍在合流评价里算，截断在汇总报告里切。
+
+- v5 明确不宣称的边界（查代码后的诚实口径，勿以字段
+  冒充执行）：① 每分工 token/费用预算：成本记录只在任务
+  完成时写，运行中的子任务花费在循环里观测不到，创建人
+  配额是按月不是按分工，所以不存在可执行的分工费用门，
+  v5 不加 max_tokens/max_cost 字段；② 每分工轮数上限：
+  普通任务在 worker 侧没有按任务的轮数上限（只有 goal
+  任务的 goal_max_rounds 与 worker 进程级的 max_turns），
+  所以 max_rounds 字段在子任务执行层无法执行，v5 不加；
+  ③ 写范围隔离：沙箱按项目 worktree 隔离、不按分工
+  量子目录隔离，prompt 里写“只写 docs/”是指令不是保证，
+  所以 v5 不加 scope 字段冒充隔离。这三项要做需先改
+  执行层（成本流、轮数帽、沙箱子目录），不在本轨范围。
+
 本模块只放纯逻辑（校验、解析、汇总、建表），不碰 DB 之外的
 任何东西，单测不需要 worker/server。

+"""评估闭环 v7：金任务 + 确定性评分 + 两轮对比报告。
+
+为什么需要这一轨（查代码确认的缺口）：
+- 路由影子评估（cloud/routing_shadow.py）只给成本与状态，
+  给不了质量；它自己也承认反事实 not_measured——影子建议
+  模型从未跑过，无法比较建议与实际的成本质量。
+- 生产代码里没有金任务、评分器、rubric：harness2.py 明确
+  写着“没有评分器、没有 rubric；delivered 的定义由 adapter
+  说了算”。所以“建议模型是不是真的更好”此前没有任何
+  机制能回答，只能凭感觉或凭成本。
+- Foundry 的评测思路是同任务跑不同 harness/模型比通过率，
+  本轨把这个思路落成可执行的最小闭环，但刻意不做成
+  “自动判优”：报告只给数据与人工评审结论，不激活任何
+  路由、不改任何策略。
+
+本轨是什么（纯模块 + CLI，不碰 DB、不跑模型）：
+- 金任务：一组 JSON 定义，每项 {id, prompt, tier, checks}。
+  checks 只认四种确定性检查：contains（结果含某串）、
+  not_contains（结果不含某串）、status_completed（任务
+  状态为 completed）、max_tokens、max_cost_usd。校验失败
+  （重复 id、未知检查类型、空 checks、空 prompt、非法
+  tier）即报错，绝不静默跳过一条检查。
+- 评分：对已完成任务的记录打分，不执行任务。输入记录为
+  {task_id, golden_id, model, status, result_text,
+  total_tokens, usd_micros, unpriced_tokens}，其中 usd_micros
+  与 cloud/cost.py 同款微美元单位。单项得分 = 通过检查数 /
+  已测定检查数；未测定检查（成本数据缺失时的 max_tokens /
+  max_cost_usd）不计入分母、单独列出，绝不把“没数据”
+  当成通过或失败；result_text 为空时字符串检查按空串算，
+  是失败不是未测定（输出已知为空）。
+- 对比：两轮（例如模型 A vs 模型 B，或同一模型改 harness
+  前后）在同一金任务集上的报告。分三层：每轮总体（任务
+  数、通过率、平均分、平均 token、平均 USD（仅已定价）、
+  未定价任务数）、配对差值（只算两轮都有的金任务，未配
+  对的任务不进差值、单独列出）、逐金任务对照表（每项在
+  两轮里是 pass/fail/unknown/missing）。配对样本 < 20
+  时（与影子评估 MIN_SAMPLES 同阈）报告 ready_for_decision
+  为 false 并写明“样本不足，不能据此做激活决定”；报告
+  不算显著性、不给 p 值——小样本下算显著性是编造精度。
+
+本轨明确不做、不宣称的事：
+- 不跑任务：本轨不创建生产任务、不调模型、不花模型费。
+  金任务要跑起来，需另起一轨（跑任务 + 回填记录），或
+  人工按金任务 prompt 建任务、把已完成记录导成 JSON 再
+  评分。本轨的 CLI 只读两个 JSON 文件，绝不联网、不写库。
+- 不用 LLM 当裁判：没有“质量分”“文笔分”“相关性分”。
+  需要人工判断质量的任务，确定性检查测不出来——那种
+  任务不应硬塞进金任务集，而应走人工评审；把字符串包含
+  当成质量证明是错的。
+- 防作弊警告：contains 检查可被“原样回显 prompt”骗过，
+  所以金任务的检查应尽量要求算出结果（例如一个具体数值、
+  一段必须经计算才得到的输出），而不是只要求出现关键词；
+  模块无法检测作弊，金任务集本身必须由人 curated，检查
+  写得越像“必须做对才过”，报告才越可信。
+- 不连路由：报告里不出现“建议激活某模型/某档”；激活
+  仍走人工评审 + 策略文件 + 干跑校验那条路，本轨只是给
+  评审多一份质量证据，与影子报告的成本证据并列。

+"""Model fallback routing and pre-dispatch rule routing (v0).
 
 Zero third-party dependencies; standard library only.
 
 This module decides *whether* a failed model attempt may fall back to
 the next model in a priority list, and *which* model to try next. It
 never runs a model turn itself and never talks to any provider.
+
+Rule routing (v0) is deliberately narrower than that: it only fills
+in the model for tasks that did not specify one, using structural
+signals already stored on the task (``plan``, ``goal_mode`` /
+``verify_command``). It never changes ``effort``, ``approval``,
+``plan``, ``executor`` or any quota, never switches provider/gateway,
+and never invents a quality ranking between models. A policy that
+cannot be parsed, or a tier with no model, falls back to the existing
+worker-default chain instead of failing the task.

+"""Routing policy dry-run (v0d): validate before applying, never apply.
+
+A routing policy takes effect the moment a worker loads it from the
+host env -- there is no CI gate for an env change. A typo in a tier
+mode silently drops that tier, a bad model name is never checked
+against a whitelist (models are not whitelisted by design), and a
+policy file that fails to parse is silently ignored by the loader
+(fail-closed to the worker default, but also silently). This module
+surfaces all of that BEFORE the policy is applied, and it never
+applies anything itself: it only reports what WOULD happen if the
+given policy document were loaded.
+
+What it reports, per tier (plan / goal / default):
+* the effective model and mode, and whether the mode came from an
+  explicit tier mode or from the global mode,
+* tiers that were dropped, and why (invalid tier mode, no model,
+  unrecognised entry) -- a dropped tier is a BLOCKER, not a warning
+  to skim past, because applying the policy would silently not route
+  that tier,
+* tiers absent from the document (worker default, not routed),
+* unknown tier names in the document (ignored by the parser),
+* whether any tier would actually activate on next dispatch,
+* capability checks (v8): per tier, whether its model meets
+  its requires against the policy's model_capabilities
+  directory -- an active tier that fails or cannot be verified
+  is a BLOCKER (it would block dispatch at the worker
+  capability gate); a shadow/off tier with the same problem
+  is a warning only.
+* gateway model check (Audit fix 3, I1): the same requires,
+  checked against the sub2api gateway model -- the model
+  production actually dispatches, which is NOT the tier
+  model. The gateway model comes only from env
+  (CLOUD_SUB2API_DEFAULT_MODEL); this module never calls
+  the relay to list models. An active tier whose requires
+  the gateway model fails or cannot verify is a BLOCKER;
+  a shadow tier is a warning only. "运营方须先把网关模型
+  写进能力目录" is now a checkable rule, not a comment.
+
+What it does NOT do, honestly:
+* It does NOT validate model names against a provider or relay
+  catalog. Task models are deliberately not whitelisted in this
+  codebase (the relay catalog changes), so a model typo here is
+  reported as "unverified, not whitelisted" only if the caller
+  passes a known-model set; without one, model names are reported
+  as-is and the caller must check them against the relay catalog
+  themselves. This module never invents a catalog.
+* It does NOT check shadow sample counts. That is the shadow
+  report's job (GET /routing-shadow); a dry-run that said "ready
+  to activate" without sample data would be fabrication.
+* It does NOT change host env, worker state, or any file. The CLI
+  exits 1 when the policy is invalid or any tier was dropped or
+  unknown, so a deploy script can gate on it; warnings alone
+  (no version, fallback_models present) do not block, but are
+  always printed.
+
+Loading order, mirrored from load_routing_policy in models.py:
+file (CLOUD_ROUTING_POLICY_FILE) first, then JSON
+(CLOUD_ROUTING_POLICY_JSON) overrides whole tier entries (not
+per-field: a JSON tier entry replaces the file's tier entry
+entirely), then CLOUD_ROUTING_MODE overrides the GLOBAL mode
+only -- it never overrides an explicit tier mode. Failed file/JSON
+sources, which the loader silently ignores, are reported here as
+warnings instead of being swallowed.

+"""Routing v0b: shadow evaluation (read-only, never auto-activates).
+
+This module answers the one question routing v0 left unanswered:
+"is there enough shadow evidence to review a tier for activation?"
+It does NOT decide activation, and it does NOT claim a counterfactual.
+
+Why the counterfactual is explicitly not measured
+--------------------------------------------------
+In shadow mode the suggested model never runs. The task's actual
+outcome (status, tokens, cost) is the outcome under the chosen
+worker-default model, not under the suggested model. So this report
+can measure, per tier:
+
+* how many distinct tasks were routed (one task = one sample,
+  retries do not double-count),
+* their status breakdown under the chosen model,
+* the distribution of suggested models,
+* total tokens and priced USD, with unpriced tokens kept separate,
+
+but it cannot say the suggested model "would have been cheaper or
+better". Any report that compared shadow suggested cost to actual
+cost as if both had run would be fabrication. The field
+``counterfactual`` in every report says ``not_measured`` for exactly
+this reason, and the top-level recommendation never activates a tier:
+activation stays a manual decision, plan tier first, per the v0 design.
+
+Data sources, and their limits
+-------------------------------
+* ``audit_log`` rows with action ``worker_routing``. The v0 format
+  was ``<task_id> tier=<tier> source=<source> applied=<bool>``;
+  v0b extends it with ``suggested=<model|-> chosen=<model|->``
+  (see worker.py). Rows in the old format parse fine, with
+  ``suggested_model`` reported as unknown and counted separately
+  (``suggested_unknown_n``), never guessed.
+* ``tasks`` rows for status and explicit-model separation. A task
+  with a creation-time ``model`` is explicit: routing never audits
+  it (decide_routing returns source ``explicit`` and the worker
+  does not audit), so explicit tasks are counted separately and
+  never inflate a tier's sample count.
+* ``cost_records`` aggregated per task. USD here is whatever the
+  cost store recorded: with the current proxy-price overlay that is
+  the gpt-6.1-sol proxy price, NOT the relay's actual bill, and
+  unpriced rows contribute tokens but no USD. The report keeps
+  ``usd_micros`` (priced only) and ``unpriced_tokens`` apart and
+  labels USD as proxy-priced when any unpriced tokens exist.
+
+Pure functions only: this module never touches a DB, a provider,
+or an environment variable, so it is unit-testable with plain dicts.
+The server endpoint (GET /routing-shadow) is the only DB reader,
+and it passes already-aggregated rows in.

+"""Audit fix 4: third-audit gate findings.
+
+- Explicit gateway capability split: known-missing blocks (active),
+  unknown audits only; shadow never blocks.
+- Explicit failures surfaced in the shadow report as an independent
+  field, distinct from the two explicit_n counts.
+- N2: coordinator requeue CAS rowcount=0 branch, via a proxy
+  connection (the auditor's low-cost approach, no refactor).
+- N3: shadow endpoint test on the create_server + real HTTP skeleton.
+- N4: creation-layer rejections for tools / instructions /
+  tool_approvals on goal/coordinator tasks, in one pass.
+- N5: model writeback failure logs a warning (best-effort kept).
+
+Run: python3 -m unittest discover -s cloud/tests -p "test_audit_fixes4.py" -v
+No real models, no network, no real gateway: gateway steps are
+stubbed exactly like test_audit_fixes.py / test_audit_fixes3.py.

+"""Audit fix 5: N1 persisted-model recheck (recheck + block).
+
+- N1-1 (writeback scope): only source=policy + applied decisions are
+  persisted. Shadow (applied=False), worker_default (no policy / no
+  tier model / tier off / capability fallback) and worker_explicit
+  (CLI model) chosen models must NOT land in tasks.model, or the
+  next attempt would mistake them for a task-explicit model.
+- N1 (recheck): a model persisted by I5 writeback is rechecked
+  against the CURRENT tier requires before dispatch on later
+  attempts. Active + known-missing fails fast (runner never
+  called); unknown-only audits only; shadow never blocks.
+  User-explicit models are untouched by the recheck, and
+  gateway-filled tasks skip it (the gateway check already
+  re-runs every attempt).
+- Identification: writeback records worker_model_persisted;
+  pre-fix5 models are recognised by a legacy worker_routing
+  source=policy applied=true row with the same chosen model.
+  A source=explicit row alone proves nothing: the elif branch
+  writes one for every task that arrives with a model,
+  including persisted ones.
+
+Run: python3 -m unittest discover -s cloud/tests -p "test_audit_fixes5.py" -v
+No real models, no network, no real gateway: gateway steps are
+stubbed exactly like test_audit_fixes.py / test_audit_fixes4.py.

+"""PG init/backfill 回滚与审计状态 upsert 登记修复测试。
 
-移植来源：feat-pg-init-fix 分支提交 854f810 的
-cloud/tests/test_pg_init_fix.py。原测试不可直接带，原因：
+演练注：add/add 冲突取并集——以 main 版（真实接口版）为基底，
+另并入移植版独有的 2 项纯 _translate_sql 回归（无列清单 SELECT
+形、VALUES 形不变）；移植版其余用例均已被 main 版同名/更强
+用例覆盖（save_loop_state、worker 合流、PG upsert 行更新）。
 
-- 原测试 import main 上不存在的 cloud.audit_loop（LoopState、
-  save_loop_state），并调 worker._coord_audit_loop_merge；集成基底
-  （02835f6）没有这两个接口，照搬会 import 失败。
-- 重写版只用集成基底上存在的接口：cloud.db._translate_sql、
-  cloud.db.connect、cloud.server._backfill_default_quotas、
-  cloud.server.init_db，以及 cloud/tests/test_postgres_backend.py
-  的 _has_real_driver / _real_pg_params（真实 PG 守卫口径与原
-  测试同款：须显式设置 CLOUD_TEST_PG_DSN 且装有 psycopg 驱动，
-  否则 skip，绝不 fail；DSN 只从环境变量读，测试不打印它）。
+只覆盖两处修复，不跑真实模型回合、不联网：
+- 问题一：新鲜 PG 库 init 后 tasks 缺 paused_by_user /
+  interrupted_reason，合流随后连环报 InFailedSqlTransaction。
+  根因是两层：(a) INSERT OR IGNORE ... SELECT 形在 PG 适配层
+  下未翻译，直接报 syntax error at or near "OR"；
+  (b) _backfill_default_quotas 的 except 整事务 rollback 把
+  同事务里 migrate 的 ALTER 一并丢掉。修法：翻译 SELECT 形、
+  backfill 改保存点 containment、成功时不再由本函数提交。
+- 问题二：task_audit_loop_state 未登记进 _OR_REPLACE_PK，
+  PG 下 INSERT OR REPLACE 退化为 ON CONFLICT DO NOTHING，
+  已存在行的 round / last_decision 等更新静默丢弃。
 
-覆盖的移植内容（与原测试一一对应，落点不同处已注明）：
-
-- 问题一 (a)：INSERT OR IGNORE ... SELECT 形在 PG 适配层下未
-  翻译，直接报 syntax error at or near "OR"。重写版直接断言
-  _translate_sql 的翻译结果（VALUES 形、SELECT 形含列 / 不含列
-  三种），不依赖真实 PG 即可回归。
-- 问题一 (b)：_backfill_default_quotas 的 except 整事务 rollback
-  把同事务里 migrate 的 ALTER 一并丢掉。SQLite 版断言保存点
-  containment（失败只回滚回填本身、成功不提前提交调用方事务）；
-  真实 PG 版断言同款保存点语义 + 新鲜 init 后 tasks 仍有
-  paused_by_user / interrupted_reason（即 migrate 的 ALTER 未被
-  回填失败丢掉；原测试用 Worker 合流证明同一链条，基底无该
-  接口，改以 init 后列存在性直接证明）。
-- 问题二：task_audit_loop_state 未登记进 _OR_REPLACE_PK，PG 下
-  INSERT OR REPLACE 退化为 ON CONFLICT DO NOTHING，已存在行的
-  round / last_decision 更新静默丢弃。重写版断言 _translate_sql
-  对该表产出 ON CONFLICT (task_id) DO UPDATE SET（含 round /
-  last_decision），即登记本身；SQLite 原生 OR REPLACE 的行更新
-  语义只作对照（证明“应有语义”长什么样，不证明 PG 行为）；
-  PG 侧的等价行为由真实 PG 测试覆盖（无 DSN/驱动时 skip）。
-
-Worker 部分说明：源提交的 worker 改动是给 _coord_child_rows 的
-列回落重试（7 列 -> 6 列 -> 4 列）之间加 rollback，防 PG
-InFailedSqlTransaction 连环；集成基底的 _coord_child_rows 只有
-单次 4 列 SELECT、无回落重试、无 except 重查，级联发生的落点
-不存在，故本移植不带 worker 改动（见摘要）。本文件不测 worker。

+  both writers (resume + ledger) work on the migrated table;
+- aggregation counts ledger rows only: a resume row (outcome

+SQLite only, run live. The Postgres upgrade path is NOT proven
