fix(scheduler): inject capability registry instead of importing catalog from control_plane

[Job28703]

问题

refactor/event-driven-control-plane（PR #3200）当前未通过 m6 可维护性棘轮：

test_m6_maintainability_ratchet_has_no_unreviewed_debt FAILED
unreviewed_count: 1
dependency_debt: loopx.control_plane.scheduler.event_driven_dispatch
                -> loopx.capabilities.catalog
rule: control_plane_outward_dependency

event_driven_dispatch.py 直接 from ...capabilities.catalog import build_capability_registry，违反 control_plane/ 内禁止 import loopx.capabilities* 的依赖规则，且该 finding 无 reviewed exception。

修法：依赖注入，不加豁免

加 exception 会永久固化违规；改 ratchet 是削弱门禁。本 PR 走依赖注入——registry 由 ratchet 作用域外的合法层（cli）注入：

• capabilities_bridge：新增进程级 registry 工厂钩子（set_capability_registry_factory / capability_registry_or_none），沿用既有 P3 hook 模式；工厂异常降级为 token-only 匹配，绝不从 claim 路径抛出
• event_driven_dispatch：claim_next_task / build_event_driven_dispatch 增加 registry 参数；capabilities/lease 路径在调用方未传时回退到工厂钩子；删除违规的 catalog import
• cli.py：import 时注册 build_capability_registry 为工厂（cli 层在 ratchet 作用域外，本就合法 import catalog）
• starter_scheduler：dispatch 调用点注入 registry
• tests/conftest：为测试进程注册工厂——测试不经过 loopx.cli import，而 fail-closed 语义（绑定 registry 未知的 pack 不可 claim）结构上依赖 registry 存在

验证

基于 fork head f6549a9e：

项	修复前	修复后
tests/control_plane/ 全套	1204 passed / 1 failed（m6 红）	1205 / 1205 全绿
m6 gates	2/3	3/3
fail-closed 语义测试	—	PASSED（中途曾因纯 DI 回归，工厂钩子修复后恢复）

清 __pycache__ + -p no:cacheprovider 复跑排除 stale bytecode 假绿；commit 后复验 1205/1205。

测试说明

本 PR 不新增也不修改任何断言——修复的验收标准是让既有 gate 转绿，同时不破坏既有语义。具体分三类：

1. 既有 gate 转绿（本 PR 的目的）

• test_m6_maintainability_ratchet_has_no_unreviewed_debt：修复前红（unreviewed_count: 1，control_plane outward dependency 违规）；修复后绿。ratchet 本身零改动——不是让测试通过，是让代码不再违规。

2. 既有语义保护（修复过程中曾红，证明这些测试有效）

• test_claim_next_task_binding_fails_closed_for_unknown_pack：纯依赖注入版本（registry 默认 None）曾让此测试红——registry=None 时 unknown pack 无从判定，token 匹配放行，fail-closed 语义崩。这个中间态红灯说明：fail-closed 语义结构上依赖 registry 存在，也是引入工厂钩子（而非只加参数）的直接原因。最终版本该测试 PASSED。

3. 新增基础设施（非断言）

• tests/conftest.py 注册工厂一行：测试进程不经过 loopx.cli import，没有这行则 fail-closed 语义在测试环境下测不出来。这是 wiring，不是测试放宽——不改任何既有断言。

复现命令（fork head f6549a9e + 本 PR）：

python3.13 -m venv .venv && .venv/bin/pip install -e . pytest
find . -name __pycache__ -type d -not -path "./.venv/*" -exec rm -rf {} +
.venv/bin/python -m pytest tests/control_plane/ -q -p no:cacheprovider
# → 1205 passed（修复前：1204 passed, 1 failed）

base 分支（frontend-control-plane-im-prototype-rfc）对照：1299/1299 全绿——即 m6 红灯是 #3200 引入、本 PR 消除，非存量债务。

[Copilot]

🟡 Changes recommended

record_policy_decisions currently defaults to on (via the master switch) despite being described and tested as opt-in/optional, and the PR’s stated scope doesn’t match the breadth of new surfaces introduced.

Once you've addressed the issues Copilot identified, you can request another Copilot review.

Pull request overview

This PR significantly expands the Phase 5/6 “new architecture” surfaces in LoopX: it adds a unified PolicyEngine decision contract (and optional decision audit events), wires event-driven scheduler/dispatch advancement into multiple goal-loop runtimes and UI renderers, and extends rollout-event bridging so scheduler/closure logic can rely on the event log rather than markdown-only state.

Changes:

• Introduce loopx.control_plane.policy (Decision contract, PolicyEngine composition, and optional decision event recording) and wire policy_decision into live quota decisions and renderers.
• Add/extend event-driven control-plane integrations (dispatch probes from PI/OpenCode loops, control-plane observability snapshot, heartbeat-as-event-source, goal closure/acceptance helpers, and additional rollout event kinds).
• Bridge CLI todo mutations into rollout events (todo_add / todo_complete) to keep event-driven dispatch projections consistent, plus add tests covering these new behaviors.

[now-ing]

The DI approach is the right call versus blessing an ratchet exception, and the commit message's verification story (1205/1205 + m6 green + cache-free rerun) is thorough. Two issues found while tracing the fallback path, one of which contradicts the stated semantics:

1. The registry-missing path is fail-open, not fail-closed. capabilities_bridge.eligible_bridged gates the pack-readiness check on binding is not None and registry is not None — so when a task carries a capability_binding_ref but the registry is None, the "bound pack must be ready" check is skipped entirely and the task is claimable on the pack-id token alone. registry=None is reachable in production: claim_next_task falls back to capability_registry_or_none(), which returns None both when no factory was registered (any entry point that does not import loopx.cli — worker processes, scripts, direct imports of event_driven_dispatch) and when the factory raises (the except Exception: return None swallow). The commit message states the fail-closed semantics "structurally require a registry to exist", but the code silently degrades instead of failing closed. tests/conftest.py registering the factory hides exactly this gap from the suite. Suggested fix: in eligible_bridged, a non-null binding with registry is None should return False (or claim_next_task should raise on the binding path when no registry is resolvable, treating it as a configuration error rather than a degradation).

2. The factory is rebuilt on every claim. capability_registry_or_none() invokes the factory each call, and build_capability_registry() has no memoization (it re-registers BUILTIN_CAPABILITIES and rescans the extension catalog every time). The explicit-injection path (starter_scheduler) builds once, but every caller relying on the fallback rebuilds the registry per claim in the scheduler loop. Caching the factory result at first success (or a once wrapper where the factory is registered) would keep the fallback path equivalent to injection.

Minor: registering the factory as an import-time side effect of loopx.cli is pragmatic, but it's worth a note in the bridge docstring that processes entering through other modules get no factory — which is what makes point 1 reachable.

REQUEST_CHANGES，精确 head：451fd72407ce53b82898653c1370eb80fad1f842。

修掉 control_plane -> capabilities.catalog 外向依赖是合理目标，但实际 PR 不只是正文声称的 5 文件 +71/-2。相对当前 PR base 52af33e49e5bd329a69d8bc38c8623b0dd9d55d5，完整范围是 68 文件 +12754/-97，包含父提交 f6549a9e9f1f21cb1600de2765b461840c26a196 的整套事件驱动原型。不能把局部 M6 转绿当成整个迁移已可合并。

评审证据分层说明：本轮完整检查最终五文件 DI 增量、真实 claim/eligibility 与未改的 resident 调用方；继承范围对照父提交的完整评审，并重新验证下面的关键负例。历史全量测试不是本轮重跑结果，未重新完成全部迁移路径的基线 parity；这些证据缺口仍阻止批准。

改动思路

新增链路是 CLI composition root 注册进程级 factory，claim_next_task 未收到 registry 时调用 factory，再把结果传入 claim_next_eligible_task -> eligible_bridged。CLI dispatch 另有一个 lazy builder；测试在全局 conftest 注册 factory。队列仍由既有 JSONL writer 持久化，DI 没有改变队列格式或实现跨进程事务。

正向实测：已注册 issue-fix binding 和普通 shell token 任务在父版、当前版均可 claim；明确关闭 event-driven 时，三类输入均不改队列字节。负向则出现了重构语义差异：父版直接调用真实 claim 会构建 registry 并拒绝未知 pack；当前版若未先 import CLI，或 factory 抛错，会退回 token-only 匹配并持久化错误的 claim。由成功 payload、lease/owner 和独立磁盘读取共同确认，不是仅比较 reason code。

复用方向应是保留 composition-root 注入、复用现有 typed eligibility 所有者，不是让缺失依赖变成另一套宽松授权。resident 的 WorkerPool.acquire/drain 没有传 registry，其行为依赖进程是否曾导入 CLI；这不是稳定的调用合同。

具体改动

完整范围分为：调度/claim/lease/retry/resident/merge；统一 PolicyEngine 与 live quota；acceptance/closure/bootstrap/registry；checkpoint/replay、成本与状态读模型；Todo 事件写入、CLI 与 Claude/OpenCode/Pi host 接入；heartbeat/安装指令；迁移说明、模块指标和测试。它们都属于本 PR 的合并面，不因标题是 DI 修复而消失。

最终增量五文件：cli.py 注册工厂；cli_commands/starter_scheduler.py 构建并传递 registry；capabilities_bridge.py 加可清空的全局工厂及异常降级；scheduler/event_driven_dispatch.py 增加参数并移除直接 import；tests/conftest.py 在整个测试进程注入工厂。没有新增专门验证“无 CLI bootstrap”或“工厂失败”的断言。

关键代码讲解

1. capabilities_bridge.py::capability_registry_or_none：未注册和任意 factory 异常都返回 None。eligible_bridged 仅在 registry 非 None 时检查绑定 pack 是否 ready，因此缺失依赖变成放行，而不是受控错误。
2. event_driven_dispatch.py::claim_next_task：capabilities/lease 分支取上述 fallback，随后真正重写队列；原先总会构建 registry 的前置条件消失。tests/conftest.py 的全局 wiring 正好遮蔽这个 fresh-process 场景。
3. resident.py::_command_matches_worker_prefix 与原 codex_cli_scheduler._command_matches_allowed_prefix：前者只比首 token，后者比完整 token 序列。新 runner 继续以 shell=True 执行字符串，属于父提交尚未修复的边界问题。
4. slash_command_install.py::_command_prompt_specs：不读取开关便投影 dispatcher 指令，且把“刚写入或完成”的 Todo 都传成 --completed-todo-id。本轮实测 master=0/1 两侧都含该指令；运行时关闭不能隔离已经加载给 agent 的行为指导。

对主干的风险

P1：DI 增量破坏未知 capability binding 的 fail-closed 语义。 同一 synthetic queue，父 head 直接调用后仍 pending、字节不变；当前 head 不导入 CLI 时变为 claimed、owner/lease 写盘；导入 CLI 后恢复拒绝；factory 抛出合成 RuntimeError 后再次错误放行。最小修复：在生产 composition root 显式提供 registry，绑定任务缺少可信 registry 时拒绝或返回有上下文的错误；保留合法 plain-token 路径，不要只扩大 catch 或给测试补 bootstrap。增加 fresh subprocess、missing/raising factory、known/unknown pack、关闭模式与磁盘无效果矩阵。

P0：继承的 worker 执行边界仍可绕过。 本轮只用安全命令验证：允许前缀 git status 时，新 matcher 接受 git log、旧 matcher 拒绝；前缀 printf safe 时，新 matcher 接受 printf safe; printf second，真实 runner 输出 safesecond。未执行破坏性命令。需完整 argv 前缀校验并避免隐式 shell；不能把字符串首 token 当执行授权。

P1：default-off 不隔离安装指令。 开关为 0 时仍指示 agent 使用、显式开启新 dispatcher，并将刚添加 Todo 作为 completed input。最小修复是按明确启用的范围生成指导，区分 add 与 complete 意图，并对安装指令、heartbeat、CLI/schema、事件写入和 host consumers 做关闭态对照。可用性不等于激活或完成授权。

其余继承风险仍未获得新的放行证据：JSONL claim 的跨进程原子性、队列 capability 字段传播、局部 closure 与主线 replan/settlement 的权威关系、checkpoint/replay 的真实恢复调用方。父版评审已有具体反例；五文件补丁没有修复这些边界。本轮没有重跑全部并发故障或真实 host 生命周期，因此不把这些维度标成通过。

验证：先前独立 DI 24 个真实队列观察；本次相关 8 个测试文件 127 passed（含 M6），另有上述 matcher/安全 runner/安装指令 paired probes；git diff --check 通过。测试通过与新的 fresh-process 反例同时存在，正说明全局 fixture 不能替代生产入口语义验证。

我的整体评价

不批准当前完整 PR。局部依赖反转有价值，但既引入新的 fail-open，又携带尚未关闭的原型级执行、并发和终局风险。就“修 M6 一项外向依赖”的目标，完整 +12754 行合并面并不相称；最小可审修法应建立在受支持基线上，注入既有 registry 并保留拒绝语义，不夹带未验收的新控制面。

Future-facing pass：建议去掉重复 lazy factory 与隐式全局 bootstrap 依赖，在现有 composition root 明确传递权威输入；不增加通用服务定位框架。通用领域文案不是主要问题，主要问题是名称/说明声称安全与 opt-in，真实生产组合却授予更宽行为。完成上述修复后仍需重新审完整 exact head，不能只验证最后一条 finding。未执行合并。

English verdict: REQUEST_CHANGES at 451fd72407ce53b82898653c1370eb80fad1f842. The DI delta makes unknown capability bindings fail open without CLI bootstrap or when the registry factory fails; real queue readback proves ownership/state mutation despite passing tests. Revalidated inherited command-prefix/shell and disabled-install-guidance defects. 127 focused tests and diff check passed; full migration parity/concurrency/host lifecycle remain unverified. Isolate the dependency repair, preserve fail-closed semantics, and address the inherited full-PR blockers before approval.
