The alphanumeric-normalisation helper was duplicated verbatim in the
common-third-party owned-domains resolver and the cookiebanner tracker
mapping worker. Hoist it into a new dependency-free strutil package so
both call sites share one implementation and one test.

The cookie-database aggregator backstop normalised the agent's
third-party name and looked it up against bare brand keys, but
normalizeAlnum folds the eTLD into the key (cookiedatabase.org ->
cookiedatabaseorg). Domain- and URL-form attributions therefore
slipped past the exact lookup, letting noisy aggregator names be
accepted instead of discarded.
Add uri.DomainLabel to reduce a host-like string to its primary
registrable label and check it alongside the normalised name, so
both brand ("Cookiepedia") and domain forms ("cookiedatabase.org",
"https://www.cookiepedia.co.uk/list") resolve to the same key.

Cookie-database and consent-directory sites (Cookifi, Cookiepedia,
cookiedatabase.org, CookieServe, ...) rank highly in web search only
because they catalog cookies, not because they set them. The mapping
agent could attribute a tracker to the directory operator itself
instead of the vendor the page names.
Instruct the agent to treat such results as reference directories and
extract the named vendor, never the operator, while keeping a CMP's own
product cookie attributable (OptanonConsent -> OneTrust, CookieConsent
-> Cookiebot). Add a conservative code backstop that discards
attributions to pure aggregators, scoped to exclude CMP vendors so
legitimate own-cookie attributions survive.

Patterns like "ethereum-https://letaido.com" embed the scanned site's
own origin, appended either by a browser extension (e.g. a wallet
injecting window.ethereum) or by an owner-set tracker. The mapping
agent read that embedded domain and attributed the site to itself as a
third party ("Letaido"), but a site owner is never a third party of its
own site.
Pass the scanned site's eTLD+1 to the agent as a <scanned_site> signal
and instruct it to ignore a domain embedded in the pattern that matches
the site, returning low confidence when that is the only cue. Add a
deterministic backstop that discards any agent attribution whose vendor
name resolves to the site's own domain, so the pattern falls through to
the unmatched fallback regardless of whether the model honored the
prompt. Deterministic catalog, naming, and sibling signals run before
the agent and are untouched, so an independent strong vendor signal
still attributes normally.
