Writer Context Pack (C4→C5 bridge) [NO PROSE]

Triggers & routing

• Trigger: writer context pack, context pack, drafting pack, paragraph plan pack, 写作上下文包.

Purpose: reduce C5 “hollow writing” by giving the writer a single, per-subsection context pack:

• the exact RQ/axes + paragraph plan (subsection_briefs)
• concrete comparison cards + evaluation protocol + limitations (evidence_drafts)
• numeric/eval/limitation anchors (anchor_sheet)
• allowed citation scope (subsection + chapter union) from evidence_bindings
