Per-iter journal entry for the fieldtest run plus INDEX pointer.
Roadmap absorbs four actionable findings as P2/P3 todos (split the
merged BadCrossModuleTypeRef diagnostic, workspace subdir search,
`ail check` on `.ailx` extension, `.ailx` counterpart for the
canonical happy-path JSON exhibit). The two carry-on items
(`(import prelude)` doc-gap, the working ones) stay as notes in the
fieldtest spec only. P0 Floats milestone removed — closed
2026-05-10 and no longer load-bearing context.
No bug findings, so no debug dispatch. canonical-type-names is fully
shipped.
