E.8:0 - Use this when

Use E.8 when you are writing, revising, or reviewing one FPF pattern and need to know what shape, voice, reader-recognition function, and assurance material the pattern must carry before it can be treated as mature FPF text.

For the whole account of an FPF, DPF, or LPF and its substantive profiles, reuse the twelve content functions through E.8:4.1.4 and E.11.PFP:4.7. Those functions guide the explanation at each selected scale; the individual-pattern heading grammar remains the form for individual pattern bodies.

Use it especially when a draft is technically correct but hard to use: the cold reader cannot tell when to apply it, what action to take, what mistake that action prevents, which related pattern defines or constrains a specific outside claim, or which assurance material is informative rather than the first user-facing guidance.

Not this pattern when. Use E.9 when the main work is deciding why FPF should change and how that decision is distributed across patterns. Use E.19 when the main work is an admission or refresh review. Use the local domain pattern when the question is what FPF says inside that domain rather than how a pattern should be authored.
