description: "Morning Star plan harness artifacts — `{PLAN_DIR}` main plans and durable review summaries, `{SDD_DIR}/review/` ephemeral QC/QA bundles, `{KNOWLEDGE_DIR}` / `{ITERATION_DIR}` indexes, plus `{HARNESS_DIR}/status.json` (v2 root register) / `{WORKFLOW_DIR}/<id>/snapshot.json` (plan rows + leases + plan-scoped `coordination`/session/handoff/revision semantics) and `{PROJECT_DIR}/<id>/residuals.json` (residual register; severity SSOT, open/close lifecycle). Read when writing plans or QC/QA review bundles, maintaining knowledge/iteration indexes, reading or writing status/snapshot/register, or mapping QC severity to JSON. Required for `@project-manager` on status, residuals, and InReview/QC waves; `@qc-specialist*` before writing review bundle reports; `@qa-engineer` before closing R# when `QA gate: mandatory`. Verdict rules: leaf → `mstar-roles/references/qc-specialist/report-template.md`; PM → `mstar-review-qc`."

## Load order

**Before first Read of this skill: Read `mstar-harness-core` (SKILL.md), and `mstar-conventions` when path symbols matter.** Git branch / worktree / QC checkout → **`mstar-branch-worktree`**. On conflict, **`mstar-harness-core` wins**.

## `status.json`, workflow snapshots, and open residual (summary)

- **`{HARNESS_DIR}/status.json` (v2)**: active-lifecycle register — `{ version: 2, updated_at, workflows[] }`. Each entry points at its snapshot dir (`dir: workflows/<id>`); terminal lifecycles are unregistered after the snapshot write. The PM-facing close caller is the post-merge `mstar status workflow-close --workflow <id>` (ordering: terminal snapshot write first, root unregister second → `mstar-iteration/references/phase-6-post-merge-close.md` §6.1–§6.2).
- **`{WORKFLOW_DIR}/<id>/snapshot.json`**: per-lifecycle running state — `plans[]` rows (legacy PlanRow shape verbatim) + per-row `execution_lease` + top-level `integration_merge_lease` / `execution_policy` / `branch` anchors / `integration_worktree_path` (the dedicated integration checkout; the main worktree / control root is derived from Git, never recorded in the snapshot).
- **`{PROJECT_DIR}/<id>/residuals.json`**: project register — **migration history** (severity enum + lifecycle semantics verbatim; project-less flows use `_default`). **Open items are issues in `{HARNESS_DIR}/store.db`** → capture duty → **`mstar-project-governance`「Issue capture」**.
- **Canonical**: capture confirmed findings as **issues** (plan-linked `mstar plan issue-add`, unscoped `mstar issue add`; recurrence appends an occurrence); the register is not a write target — v1 root `residual_findings` and the register document are legacy/migration only — migrate via `mstar migrate`, do not dual-write.

> **Engine check (when available):** run `mstar status validate <path>` (or `import { validateStatus } from "@mstar-harness/engine"` in a host hook). On `fail` -> do not proceed; fix and re-run. Skill text below remains authoritative when the runtime is absent.

- **Fail-loud handoff**: the capture path validates the capture input at the domain boundary and refuses a malformed submission (nothing written); migrated register documents pass `validateResidual` (per entry) / `validateProjectRegister` (register); snapshots and the v2 root pass `validateWorkflowSnapshot` / `validateStatus` (`mstar status validate`); malformed → reject + rewrite → **`references/status-and-residuals.md`** (“Fail-loud handoff contract”).
- **Lifecycle**: an issue is **open** until a §4 closure authority retires it (`resolved` / `waived` / `duplicate` / `superseded`); migrated register records keep the in-place `lifecycle` / `closed_at` / `closure_note` shape; machine **`severity`** enum in reference. v1 `archived/residuals/` + `archive-residuals` are retired.

- **Findings cleanup**: Assignment **`Findings cleanup: zero-residual | allow-residual`** (the `metadata.findings_cleanup` mirror is deleted); iteration Phase 2 defaults to **`allow-residual`** (capture + disclose duties apply) → **`references/status-and-residuals.md`** (“Findings cleanup modes”).

> **Engine check (when available):** run `mstar status findings-cleanup <plan-id> [--mode zero-residual|allow-residual]` (or import `findingsCleanupGate` from `@mstar-harness/engine` in a host hook) to enforce the Findings cleanup mode above against the **open issues linked to the plan** in `{HARNESS_DIR}/store.db`. On `fail` -> do not proceed; fix and re-run. Skill text below remains authoritative when the runtime is absent.

- **`{WORKFLOW_DIR}/<id>/notes.jsonl`**: per-workflow append-only notes ledger (runtime); snapshot plan-row `notes` is the legacy verbatim copy. **Tech-debt rollup**: `mstar status tech-debt` over the open issues in the store — **`references/status-and-residuals.md`**.
- **Iteration Phase 2 leases** (snapshot: `integration_worktree_path`, `plans[].execution_lease`, top-level `integration_merge_lease`): field semantics → **`references/status-and-residuals.md`** (“Iteration execution leases”); Phase 2 execution checklist → **`mstar-iteration`** `references/phase-2-worktree-lease.md`; full protocol prose (single copy) → **`mstar-engine-legacy`** `references/lease-protocol.md`.
- **Plan-scoped coordination is a domain-call surface**: active plan/workflow mutations include `mstar plan release` and may use the caller's unambiguous own binding without routine reference/token copying; explicit references/tokens remain checked constraints. See `references/status-and-residuals.md` for lease semantics, `mstar-use-cli` for command transport, and `mstar-iteration` for route semantics. Every plan-row mutation goes through its public verb; hand-editing snapshot rows or writing findings/register files outside those verbs is not an authorized path.

> **Engine check (when available):** run `mstar lease verify --workflow <id> [--plan <plan-id>]` or `mstar lease verify-integration --workflow <id>` (or import `validateExecutionLease` / `validateIntegrationMergeLease` from `@mstar-harness/engine` in a host hook) to validate the iteration leases above on the workflow snapshot (execution_lease / integration_merge_lease). On `fail` -> do not proceed; fix and re-run. Skill text below remains authoritative when the runtime is absent.

Field semantics, severity mapping, findings cleanup modes, archive flow, and `jq` examples → **`references/status-and-residuals.md`**.

**Templates (this skill):** `templates/status.empty.json` — the **v2 shape** (`version: 2`, `updated_at`, `workflows: []`); copy into `{HARNESS_DIR}/` (`templates/README.md`).

## Workflow

产物生命周期主链：主 plan 落盘 `{PLAN_DIR}` → 实现推进时经 **domain call** 更新 workflow snapshot 的 `plans[]` 行；active plan/workflow 修改使用当前已获取且无歧义的 caller scope，缺省时派生 session/token 并生成单次 operation id，显式 reference/token 仍须匹配；`mstar plan release` 仅释放 caller 自己持有的 execution claim，之后需显式 bind 才可 reacquire。pre-activation 使用 `--session` 与 revision `--expect`；直接文件编辑仅限 CLI 缺失的 legacy 路线。根 `status.json` 的登记/注销由生命周期动词负责 → 审查波次产出 review bundle + durable gate summary → finding 捕获为 issue。

## Decision Rules

- residual **severity** 是机器字段 SSOT（`references/status-and-residuals.md`）；每条新 finding 捕获为 **issue**（计划内 `mstar plan issue-add`，计划外 `mstar issue add`；重复出现追加 occurrence）；register 与 v1 根级 `residual_findings` 都是 legacy/迁移只读，**禁止**双写。
- **`Findings cleanup: allow-residual`** 默认（迭代 Phase 2）：open issue 先捕获（计划链接）再披露（清单 + severity + 跟踪位置；close 面另含 blocker-defer 标记）；unresolved `critical` 仍阻断 Approve；`zero-residual` 为显式 opt-in —— 细则 → **`references/status-and-residuals.md`**「Findings cleanup modes」。
- 捕获前必须过 engine 域校验（fail-loud handoff）；迁移 register 文档过 `validateResidual` / `validateProjectRegister` / `validateStatus`；malformed → reject + rewrite。
- **计划行 / issue 只经 domain call 修改**：scoped 路线使用 `mstar plan …` 动词（active：独立获取的 own-binding 身份；`--session-ref` / 完整执行令牌 `--expect` / `--operation` 可省略，显式值仍是校验约束；pre-activation：`--session` 与 revision `--expect`），手写 snapshot / 写 register 会被拒（`coordination.direct-write-refused` / `coordination.scoped-writer-required` / `coordination.store`）；只读校验器（`mstar lease verify` / `mstar worktree check`）是检查而非修改替代。**reference 与令牌都不是凭据**：reference 是查表，令牌是 CAS 值，二者都不下发给 leaf。

## Evidence

正确结果 = 可复核产物链：`{SDD_DIR}/review/` 审查 bundle 落盘 + 主 plan / workflow snapshot 的 durable gate summary + issue 生命周期（捕获 → §4 关闭权威关闭，`mstar issue list` 可复核）。拒绝「仅对话声称」。
