Argument Self-loop (write -> self-check -> ledger -> revise)

Purpose: upgrade C5 from “generate text” to “execute argument actions under explicit constraints”.

This skill operationalizes the mechanism you described as a reusable, pipeline-native component:

• write section-by-section
• self-check paragraph-by-paragraph
• maintain a small argument ledger that makes dependencies explicit
• revise only what fails until the chain is continuous

It complements (not replaces) the other self-loops:

• evidence-selfloop: blocks writing when packs are not writeable (do not pad)
• writer-selfloop: blocks template voice, missing sections/leads, scope/citation violations
• argument-selfloop (this skill): blocks argument discontinuity and premise drift (even when prose is fluent)

Core idea: two intermediate artifacts (never in the paper)

This skill treats “argument structure” as a first-class intermediate artifact, like evidence packs.
