E.8:10 - Architectural Rationale

Structure and style function as FPF’s grammar. By unifying what were once separate “template” and “style guide” patterns, authors face a single reference point that satisfies:

• P‑1 Cognitive Elegance – uniform, minimal surprises.
• P‑2 Didactic Primacy – narrative flow, dual archetype examples.
• Guard-Rails 1 & 2 — abstract definitions remain portable; the heading grammar keeps the exact syntax needed for its own conformance conditions, and expressions retain E.5.2 interpretation and mapping.

A unified template also improves retrieval: a chunk containing A.2:<n> - Bias‑Annotation remains self‑identifying even when parent headings are missing, and the required footer marker makes truncation detectable.

The ASCII - separator in H-2 keeps heading entry inexpensive: authors can type it directly on ordinary keyboards, and readers can reuse the same characters in search and plain-text tools. Typographic dash variants require an extra input or conversion step while adding no information to the boundary between an identifier and its title. Where a prose dash is useful, -- is a keyboard-accessible option; the identifier/title separator remains -.

International and industry standards often speak in terms of conformance criteria. FPF uses the label Conformance Checklist to make adoption easier for engineers and managers.
