fix(qa): state the input-rule principle instead of a worked example (W3-9)

The signed-amount example in 0fe616e was misread in the focused rerun as 'a
signed amount breaks only the digits-only rule', and the run again missed
the seeded non-digit defect. The stop rule now states the principle: each
field's documented input rule needs a probe that breaks only it and satisfies
every other rule.

 - **The State Machines specialist runs when its detector fails.** The /review and /ship scope block now runs `gstack-state-matrix detect` itself and uses its output only on exit 0. A failure prints `SCOPE_STATE_MACHINE=unknown` with the detector's stderr, and unknown dispatches the specialist. Its output reaches `gstack-state-matrix check` as a file the agent writes, never as text in a shell command.
 - **Consent options are lettered B, C and D when Aside is absent**, matching the question's answer keys.
 - **Plan-reality tier 1 rows are never n/a.** A run no longer loops repairing `deferred-asks n/a` past its deadline.
-- **/qa's exploratory stop rule needs one probe per documented input rule of each field.** A value that breaks two rules, such as a signed amount under a digits-only rule, covers neither. Rules left uncovered at the probe or time cap go to limits. After a fix, every earlier capture is superseded: rerun each one the verdict relies on, or report it as open.

 - **`gstack-docs-candidate snapshot --help` and `compare --help` exit 0** before any side effect, and a compare reject names the path, each bad field and a fix that never re-snapshots over the pre-audit baseline.
 - **The docsync fault actor uses the production candidate protocol.** It writes candidates through the installed snapshot, and a failed snapshot reports a stable reason with one retry under a fresh audit id.
 - **The required-probe reminder counts only captures after the last source edit** when the caller declares `GSTACK_QA_REQUIRED_AFTER_EDIT`. Pre-repair captures no longer look like post-repair coverage. Without the declaration nothing changes.
