Captures what isn't derivable from the code: build_app times out at the MCP
layer while continuing to build (poll for the image, don't retry), the app
doesn't exist to build_app until platform CI goes green, and the three
generator guards (prefix-only hint matching, -er-only syncopation, truncation
rejection) each exist because of specific bad output.
Also records why lookups must not route through rdap.org: its redirector
returns a bare 404 both for "unregistered" and "I don't serve this TLD", which
would report every .io as available.
