refactor(status): single-source shared projection carriers

[Duang777]

Goal And Delivered Outcome

• Outcome basis / optional anchor: Refs [Task]: Semantic vocabulary convergence follow-ups after RFC PR #4433 / 语义词表收敛后续任务 #4447 Track A and the remaining-carrier record from refactor(status): single-source the carriers the facade restated #5195.
• Goal/source and gap: three status contracts still had repeated module-level declarations after the facade cleanup. MONITOR_SIGNAL_WAITING_ON had three declarers, while SECTION_HEADING_PATTERN and STATUS_CONTRACT_SIGNAL_LIMIT each had two. Equal values did not prevent a later owner-only edit from making consumers disagree.
• Observable before -> after, with the validation row that proves it: each carrier now has one projection owner. Internal consumers import that exact object, the focused ownership test checks package-wide declarations and identity, and the semantic inventory reports the reduced string-fork counts.
• Issue/task and intended base: Refs [Task]: Semantic vocabulary convergence follow-ups after RFC PR #4433 / 语义词表收敛后续任务 #4447 Track A. Base is main at ee1ea64b0.

Scope And Continuation

• Completed scope and remaining work: monitor_display_projection.py owns MONITOR_SIGNAL_WAITING_ON; active_state_projection.py owns SECTION_HEADING_PATTERN; contract_projection.py owns STATUS_CONTRACT_SIGNAL_LIMIT. Four duplicate declarations are removed without changing their values. Self-review also removed the differently named monitor defaults from project_asset.py; every production builder now receives the signal and stop condition from monitor_display_projection.py. The string inventory moves same_runtime_forks 12 -> 11, same_runtime_fork_definitions 28 -> 25, and same_runtime_forks_semantic 10 -> 9.
• Slice boundary / successor: complete within this scope. AGENT_LANE_PROGRESS_SCOPE remains deferred because open PRs feat(explore): enforce scoped composition lineage and lifecycle evidence #5280 and fix: frame JSONL index reads on LF, not str.splitlines() #5117 touch two declarers. LIFECYCLE_PRIORITY, M3 field retirement, scanner changes, and TypeScript migration are not part of this PR.

real_entrypoint	passed	Project-asset, Todo boundary, goal-attention, monitor-display, active-state, and status read-model smokes passed.
regression_parity	passed	Semantic vocabulary smoke passed with same_runtime_forks=11/11, same_runtime_fork_definitions=25/25, and same_runtime_forks_semantic=9/9. The architecture semantic inventory/drift selection passed 139 tests.

• Coverage and gaps: the full repository test suite was not run. The focused suites cover all changed import bindings, their real read-model entrypoints, import boundaries, and the semantic budget gate. No backend or persisted state changes.

Self-review follow-up is included in 8274afe2f7a9a46c1d456a7dc92e1f63da3f4413.

The review found that project_asset.py still held differently named defaults for the monitor signal and stop condition. That meant a later change to the recorded owner could update attention routing while project-asset classification retained the old values. The fix removes those defaults from the work-item layer, makes its builder dependencies explicit, and routes all production callers through the monitor-display projection owner. The public status.build_project_asset signature is unchanged.

Red-green evidence: the new mutation test failed before the fix with selective_assist instead of read_only_observer, then passed after the owner values were threaded through. Current validation: 599 selected control-plane tests passed, 139 semantic architecture tests passed, four affected read-model smokes passed, Ruff and Mypy passed, and the standard premerge gate passed 19/19.

精确 head：8274afe2f7a9a46c1d456a7dc92e1f63da3f4413。已独立阅读完整 11 文件 diff、#4447 Track A 与 #5195 的剩余-carrier 记录；本评审只判断该 head，不以作者声明或远端 CI 代替验证。

动机

状态投影的消费者曾重复声明相同的 monitor signal、section heading pattern 和 status-contract signal limit；其中 project-asset 层还保留了不同名称但同义的默认值。未来只改一侧会让 attention 路由与展示分类分叉。此 PR 的有效目标是收敛既有共享词汇的 owner，而不是以计数下降充当产品结果。

改动思路

monitor_display_projection 继续拥有 monitor signal 和 stop condition，attention 与 registry-health 的构造路径从该 owner 取值；active_state_projection 和 contract_projection 分别提供 section regex 与 signal limit。work-item 构造器只接受显式依赖，不再私藏 monitor 默认值。没有新持久字段、调度决定或第二个 authority；已存在的 status.build_project_asset 入口参数保持不变。未来面向改动的窄幅重构已经体现在这次消除重复 owner，未见需要顺带拆出新层。

具体改动

关键路径是 goal_attention_projection.attention_item → monitor_display_projection.build_project_asset → work_items.project_asset.build_project_asset：等待原因与停止条件从同一个投影 owner 注入，所以 monitor signal 变更不会只更新 attention 而留下旧分类。state_projection 的 heading regex、diagnose 的 signal limit 改为导入现有 owner，语义预算按实际减少的重复声明收紧，测试把导入身份和原值都钉住。

正例：原有 monitor、status-contract 与 collection read-model smoke 均通过，状态外观保留。负例：定向 mutation 测试改变 monitor owner 的 signal 和 stop condition，project-asset 必须仍报告 read_only_observer 与新停止条件；本 head 的 8 项 ownership 测试及另 8 项 status/diagnose 测试通过。语义 drift smoke 在安装仓库 npm 开发依赖后通过，实测 same_runtime_forks=11/11、same_runtime_fork_definitions=25/25、same_runtime_forks_semantic=9/9。前一次 smoke 因测试工作树缺 TypeScript 包而未启动扫描，补依赖后的结果才计为通过。

对主干的风险

主要风险是模块导入边界和动态构造时默认值的漂移；已检查生产调用点，work-item builder 由投影 wrapper 注入，status 对外同名入口仍可调用。git diff --check、变更 Python 文件 Ruff、定向 pytest、三条真实 read-model smoke 与语义扫描通过；风险型 premerge 门禁通过 19/19（含 10 条 catalog、8 条 risk-profile smoke 和 public/private 边界检查），无失败、跳过或人工 hold，但它不授予合并权限。无 UI、Lark、权限或存储变化；没有把无关红 CI 归责于本 PR。此轮未查询或等待 GitHub CI，未在本机执行整个全量测试矩阵。

我的整体评价

APPROVE 这个有界的 Track A 收敛：它在当前调用路径消除了会产生分叉的默认值，而非只调低计数。AGENT_LANE_PROGRESS_SCOPE 与 LIFECYCLE_PRIORITY 仍在 #4447 的明确后续边界，不应要求本 PR 把有冲突的邻接工作混进来。评审不授权自合并；控制面改动仍由维护者按精确 head 决定。

English verdict: APPROVE — exact head 8274afe; focused ownership, status/read-model and semantic-drift validation support this bounded convergence, with no PR-attributable blocker found.
