#G.9:4.3a — Worked parity slice

Preface node heading:g-9-4-3a-worked-parity-slice:83104

#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

• Two agentic search setups both claim bounded specialization on the same declared task family.
• The ParityPlan pins the same freshness window, threshold target, adaptation budget, prior-exposure declaration, comparator editions, and corridor-entry baseline. One setup reaches threshold sooner but shows low retention and no transfer. The other reaches threshold later, but carries reusable transfer and lower downside field.
• A CSLC-admissible ParityReport@Context therefore states what was held constant, which signals remained telemetry, and why the outcome stays a governed selected set or partial order rather than collapsing into a scalar winner. The reader can recover the practical comparison from the parity slice itself before reading any optional wiring blocks.
