What this page is

This is generated FPF reference text from the specification preface or supporting sections. It helps interpret FPF; it is not FPF Reference product documentation.

Methodology

Use it to understand how the specification wants to be read, then return to a route, pattern, or work packet for active work. Cite generated IDs only when the wording changes the task decision.

Content

Repeated same-regime normalization may be idempotent, but heterogeneous regime shifts are generally order-sensitive. Multi-publication chains are checked pairwise, but the final use must preserve accumulated loss rather than restarting as if each pair erased earlier losses.

Each step in a chain keeps recoverable:

  • preserved entityOfConcernRef plus source and receiving representations;
  • claim or commitment under test;
  • representation-scheme delta;
  • preserved and withdrawn commitments;
  • loss and recoverability;
  • remaining admissible reader action.

The case reopens whenever recoverability assumptions, pins, provenance, correspondence witness, publication-face admissibility, primary semiotic mode, or accumulated loss changes. A representation shift also reopens if what looked like one same-entity line turns out to require a new EntityOfConcern, a counter-witness disposition, or a decode path with higher evidence requirements than currently declared.
