Added

• Requests fully covered by a licence agreement now show a coverage summary in the request detail's Billing tab: the list price in credits, the credits the licence absorbed, and the zero charge that resulted. Licence-covered usage previously recorded an unlabelled zero; the value your licence absorbs is now visible per request, so you can see what covered usage would have cost on pay-as-you-go rates.

Changed

• The Request Explorer folds each search typing chain into a single expandable search-session row carrying the settlement as a signed debit, or a pending marker while settlement is due. Chain members are tagged as the minting or attaching request and carry no charge of their own.
• Suggest queries that never formed a candidate set are labelled free rather than showing a zero, so free-by-design requests are distinguishable from unbilled ones at a glance.
