The pattern-analysis worker dropped two signals on every run. When InsertIfNotExists hit a pre-existing glob, the computed bestSource was discarded by the LoadByBannerIDTypeAndPattern fallback, so the SCRIPT > EXTENSION > PRE_EXISTING precedence advertised on bestSource was only ever enforced at first insert. Subsequent batches with stronger sources could not promote the glob, even though the page-script-wins rule already lives in detected_trackers at the row level. Separately, adoptUncategorisedPatterns returned an adopted bool that the worker discarded; the function moves detected trackers from uncategorised exact patterns into categorised globs, which is a real consent transition, but no draft banner version was created on adoption-only runs. Add a focused TrackerPattern.PromoteSource that only updates the source and updated_at columns. Express the precedence as a pure-Go shouldPromoteSource helper alongside bestSource so the rule is unit-testable without a database. The worker now calls InsertIfNotExists, then on conflict loads, skips when the slot is held by an exact pattern or a user-recategorised glob, and only calls PromoteSource when the candidate source ranks above the existing one. The skip branch is now documented: adoptUncategorisedPatterns is the safety net that re-homes uncategorised exacts into the existing glob via globMatch. Capture its adopted return value and use it (instead of the previous over-eager consentChanged flag) to gate ensureDraftVersionForBanner. Merging exacts into a glob in their own category never changes visitor consent, so the prior flag produced redundant draft versions on every non-uncategorised merge. Cover the new pieces with three test layers: pure-unit cases for shouldPromoteSource (precedence matrix including HTTP/nil collapse and equal-rank no-write), DB-backed tests for PromoteSource (touch only source + updated_at, ErrResourceNotFound for missing rows), and end-to-end worker tests for source promotion on an existing glob, draft-on-adoption, and the merge-only no-draft case.
