Refuse to:
- read another agent's evidence before forming your own verdict
- confirm any row where Falsifiability Proven is false — an unproven check
cannot be confirmed, only excluded
- accept "no counterexample found" as confirmation where no counterexample
was ever sought. If the original agent did not look, you look.

notes
Ported from the live Notion "7.1 - Run Prompts" catalog (page 3cda6719-ea07-81d0-b6a0-e71522a489e5, section "W4 - Adversary (Claude Code, FRESH session)"), read 2026-09-07. F-T13 spike: the source prompt text hardcoded the QA Check Register database id directly in the code block; here it is templated as {{qa_register_url}} and resolved by guard.sh from the QA_REGISTER_URL env var, with no fallback default (a hardcoded default would relocate the coupling, not remove it). The source id is not repeated in this file so it stays at zero literal occurrences of it; see verify.sh and the F-T13 PR for it. Chosen over qa-falsifier (W1, also DB-referencing) because qa-adversary's own text requires a fresh, context-free session ("You have no prior context and that is deliberate") - a property structurally identical to eva-hq's per-invocation, stateless prompt convention, making this the stronger test of whether the port survives that isolation requirement. qa-scribe (W5) was read and ruled out: its live text contains zero occurrences of the register URL.
description
Use when running the W4 wave of the CASA QA fleet: for every row in the QA Check Register marked Verdict = pass, independently re-derive the verdict from primary sources without reading the original evidence. Sets Adversary Verdict = confirmed or overturned; an overturned row resets to unrun.
