description: Reviews a reverse-skill case package for scope readiness, Evidence to Finding to Path traceability, work item coverage, timeline references, and optional artifact hash integrity before report handoff.

Evidence Graph Review

Use this skill when a reverse engineering, forensics, CTF, or authorized security case needs a defensible handoff. It audits the existing `work/<case>/` package without changing the case or touching a target.

Scope

This skill covers:

• Scope metadata and target-activity readiness
• Evidence record structure and reproducibility fields
• References from work items and timeline entries to Evidence
• Structured Findings and Paths in report Markdown
• Optional SHA-256 verification for case-local artifacts
• A Markdown or JSON review result for a report handoff

It MUST NOT perform reconnaissance, exploitation, dynamic instrumentation, or target changes. Those actions belong to the routed analysis skill and require the case scope gate.

ACTION REQUIRED

1. `NOW`: read `../field-journal/precedent-reverse.md` and confirm that this is a review of an existing authorized case package. 2. `NOW`: confirm the case path and choose read-only review mode. 3. `NEXT`: read `../tool-index.md`; this skill uses only Python 3 standard library and does not require bootstrap. 4. `NEXT`: run `python3 scripts/review_case.py <case-root> --format markdown`. 5. `ACT`: resolve every error, then rerun the review before claiming a handoff is complete.

Tool dependencies

| Tool | Required | Purpose | Auto-bootstrap | |------|----------|---------|---------------| | Python 3.9+ | Yes | Runs the read-only case review script | No, use the platform Python installation |

No network access or third-party package is required.

Workflow

Phase 1: Intake

Run the review against the existing case directory:

python3 skills/case-review/scripts/review_case.py work/<case> --format markdown

Confirm that `scope.md`, `timeline.md`, `workitems.md`, and `evidence/` are present. A non-strict review reports scope warnings while a strict review treats warnings as handoff blockers.

建议下一步（选一个编号）

1. 修复 scope.md 中的授权、范围或 network_profile 字段 2. 继续检查 Evidence 记录的可复现命令和来源 3. 导出当前 review 结果并附到阶段性报告 4. 换 JSON 输出接入 CI 或其他审查工具 5. 暂停，先确认审查范围

Phase 2: Traceability

Review the checks for:

• Evidence IDs that do not exist
• Findings without `evidence_ids`
• Paths without an allowed `path_type` or Evidence reference
• Work items and timeline entries pointing to unknown Evidence
• Unlinked Evidence records
• Validated Findings with low confidence

An offline observation may use `repro_command: n/a` only when its `notes` field explicitly documents the offline limitation.

Use JSON when another tool needs stable fields:

python3 skills/case-review/scripts/review_case.py work/<case> --format json

建议下一步（选一个编号）

1. 补写缺失的 Evidence，并保留原始命令 2. 将候选 Finding 绑定到 Evidence 后重新审查 3. 为调用链或攻击链补充 P-id 和 Path 步骤 4. 生成 Markdown handoff summary 5. 换回 PRIMARY skill 继续分析

Phase 3: Fixity verification

When an Evidence record contains both `content_hash` and `artifact_path`, verify the case-local artifact:

python3 skills/case-review/scripts/review_case.py work/<case> --verify-hashes --strict

The script accepts `sha256:<64 hex characters>` and checks that the artifact remains inside the case root. A hash mismatch is a hard failure.

The PowerShell Evidence helper can record a hash while appending a record:

powershell -File skills/scripts/append-evidence.ps1 -CaseRoot work\<case> -Id E-001 -Title "Sample hash" -ReproCommand "sha256sum evidence/sample.bin" -ArtifactPath "evidence\sample.bin"

建议下一步（选一个编号）

1. 修复 hash mismatch 或替换已污染的工作副本 2. 为未固定的原始文件补充 SHA-256 和 artifact_path 3. 继续进入报告生成阶段 4. 导出 JSON 结果供 CI 保存 5. 暂停并请求人工复核

Phase 4: Handoff

Use strict mode before a final report or specialist handoff:

python3 skills/case-review/scripts/review_case.py work/<case> --strict --format markdown > work/<case>/report/case-review.md

The command is read-only with respect to the case unless shell redirection is explicitly used to save its output. The review is not legal advice and does not replace organizational evidence handling procedures.

建议下一步（选一个编号）

1. 将通过的 review 结果交给 `docs-generator/` 生成正式报告 2. 回到 PRIMARY skill 补齐新的分析证据 3. 归档 Markdown 和 JSON review 结果 4. 暂停并请求人工复核

Language behavior contract

• Internal reasoning, tool selection, and phase control: English.
• User-visible messages, section labels, reports, and next-step menus: Chinese unless the user requests another language.
• Default bilingual labels place Chinese first and English second, separated by `/`.

Bootstrap boundary

This skill has no third-party dependency. If Python 3 is unavailable, the only allowed recovery action is the repository bootstrap path when a Python capability is registered for the current platform. If no such capability is registered, stop and report the missing runtime. Do not guess executable paths, download packages, or perform a manual install from inside this skill.

Routing context

**Upstream entry**: any reverse, forensics, CTF, or authorized security skill that has produced a case package.

**Downstream exit**: `docs-generator/` for a formal report, or the original PRIMARY skill when the graph is incomplete.

**Related modules**: `ops/evidence-finding-path.md`, `ops/timeline-workitem.md`, `digital-forensics/`, `reverse-engineering/`, and `docs-generator/`.
