Note

High Risk
Adds payment-adjacent vault operations (card fill and Square checkout preparation) and changes operation return types, which affects how integrators handle secrets, partial failures, and checkout recovery.

Overview
Release 0.102.0 bumps the package and changelog. The substantive SDK changes are new vault checkout/fill capabilities, config-registry guidance, and minor browser-control docs.

Vault item operations expand beyond authorize: eligible Link cards can run a guarded fill operation (browser session, exact page_url, CSS selectors → value-free per-field results), and unused AgentCard cards can run single-use prepare_checkout for Square (checkout context, approval URL, ready_to_submit / expiry semantics). performOperation is now typed as a discriminated union (authorize / prepare_checkout → item-shaped responses; fill → FillVaultItemOperationResult) instead of always returning VaultItem. AgentCard state, preparation, and deletion docs/types reflect the new lifecycle (preparing, ready_to_submit, consumed, etc.) and allow abandoning recovery_required cards when no authorization ID was returned.

Config registry lookup/resolve responses add optional guidance markdown; lookup recommendation is typed as RecommendationResult (including structured no-recommendation with proxy_restricted).

Browser computer pressKey docs now describe X11 punctuation in combos (e.g. Ctrl+minus, Ctrl+- normalization).
