description	学术降重的全量 AI 模式扫描门。长文必须启用 subagent 并行隔离扫描，生成 Pattern Coverage Matrix，确保每段都有 clean/suspect/format-exempt 状态和 A-code 证据。触发关键词：长文扫描、模式门控、Pattern Coverage Matrix、A-code 扫描、反漏检、母骨架诊断、subagent 并行扫描。

Deweight Coverage Scan

Purpose

把“感觉像 AI”变成可定位、可统计、可复查的模式证据。识别阶段追求 recall：宁可多报 uncertain，不能漏扫。

Runtime References

• Pattern catalog: ../../_shared/references/pattern-catalog.md
• Long document protocol: ../../_shared/references/long-document-coverage-protocol.md
• Pattern Coverage Matrix schema: ../../_shared/references/pattern-coverage-matrix-schema.md
• Copyable template: ../../_shared/references/templates/pattern-coverage-matrix-template.md
• Deterministic check: ../../_shared/scripts/check_pattern_matrix.py

Mandatory Subagent Policy

For long documents, chapter-level scans, or any input with 12+ paragraphs:

• Must use isolated subagents when the runtime supports subagents.
• Required roles:
  • Local Scanner
  • Section Diagnostician
  • Global Aggregator
  • Anti-Miss Reviewer
• If subagents are unavailable, return:

blocked: needs_subagent_runtime

Do not silently run single-context long-document scanning unless the user explicitly permits serial fallback.

Role Contracts

Local Scanner

Input: 3-5 paragraphs plus one-paragraph overlap on both sides.

Output per paragraph:

paragraph_id:
status: clean | suspect | format-exempt
A_codes:
evidence_sentence:
reason:
severity: 0 | 1 | 2 | 3
confidence: high | medium | low | uncertain

Local Scanner must not judge the whole document.

Section Diagnostician

Input: section outline, local scanner outputs, representative paragraphs.

Required judgment:

mother_skeleton: A30 | A33 | A35 | A37 | none | uncertain
why_this_skeleton:
counter_evidence:
minimal_surgery:
targeted_rescan_needed:

Global Aggregator

Input: all local and section outputs.

Output:

• Pattern Coverage Matrix.
• seven-group coverage table.
• high-risk zones.
• missing paragraph list.

Anti-Miss Reviewer

Input: matrix, high-risk zones, representative paragraphs.

Task:

• Do not rewrite.
• Do not summarize.
• Only challenge omissions, mislabels, and overconfidence.

Pattern Coverage Matrix

Every scan must include:

| section | paragraphs | dominant_group | mother_skeleton | A-codes | count | density | confidence | examples |

Rules:

• Every paragraph must be represented exactly once in final coverage.
• Each paragraph status must be clean, suspect, or format-exempt.
• Every suspect paragraph must have A-code evidence.
• Every clean paragraph must state why no rewrite is needed.
• All seven diagnostic groups must be marked hit | not_seen | uncertain.
• Every section must answer A30/A33/A35/A37 mother-skeleton status.
• uncertain requires targeted rescan or a blocked return.
• The final artifact must include the paragraph status table, seven-group table, and section mother-skeleton table defined in pattern-coverage-matrix-schema.md.

Diagnostic Groups

• 空话包装型：A1-A6, A8-A10, A14
• 机械对称型：A7, A11-A13, A15-A18, A20-A23, A26, A29
• 技术散文模板型：A24-A27
• 论证过度闭合型：A19, A30, A32, A33
• 教科书/贴源型：A3, A31, A35
• 作者性缺席型：A16, A36
• 混写与新式精修型：A34, A37, A38, A39

Failure Conditions

• Missing paragraph IDs.
• Missing overlap for local shards.
• Any paragraph omitted from final matrix.
• Any suspect without evidence sentence.
• Any section missing mother-skeleton judgment.
• Anti-Miss Reviewer finds unresolved omissions.

Before handoff to binding, the artifact should pass:
