Preflight Block E (`dotnet csharpier check`) flagged two reflows
in the v1.5.2 code: the ForgeBronzeDim Vector4 constant needed
multi-line form, and a handful of switch arms / long Plugin.Config
chains in WizardStateSmokeStep needed line-breaks at csharpier's
print-width. Pure formatting — zero functional change. Block D
build stays clean, Block E now passes.
Variant 1 walks the FirstRunWizard state machine through Step 1 →
4 and commits with no pending values to verify the no-op
write-back path. Variant 2 picks Roleplay on Step 2, skips Step 3,
commits, and asserts LoadPreviousSession /
FilterIncludePreviousSessions stayed on their pre-test value —
pinning the null-semantics from Spec Z.176. ApplyRoleplay would
overwrite six privacy / retention fields, so the step snapshots
them before Variant 2 and CleanUp() restores them, keeping the
self-test idempotent across /xlperf runs. Catches state-machine
throws and CommitPending NREs that would otherwise surface as a
hard plugin crash during Finish ✓ clicks. Runs alongside the
existing three FontManager / ThemeSwitch self-test steps.
