 **Failure modes:** E2, G4
 **Build:** `aliases.yaml` (checked into the *target* repo): `"invoice widget" → BillingSummaryCard`, route titles, feature names. Corrections API: `recordCorrection(terms, confirmedInstanceId)` appends to `corrections.jsonl`; both feed the matcher as first-class evidence (`kind: "alias" | "correction"`, high weight). Eval subcommand folds corrections into new ticket-eval cases.
 **Accept:** fixture `e2-business-vocab` green via alias; a recorded correction changes the next identical query's top-1 (integration test). **Gate 4 passes.**
