Note

Medium Risk
Adds a large Vault/payments-related client surface and immutable browser–vault linking; changes are mostly additive typings but touch sensitive checkout and secret-handling flows.

Overview
Release 0.99.0 bumps package version and changelog; endpoint count in .stats.yml rises from 147 to 158.

The main functional addition is a client.vaults resource: vault upsert/list/retrieve/delete plus nested vaults.items for wallet and card items (upsert, operations, events, expand/wait params) with AgentCard/Link-oriented types. The root Kernel client exports Vaults and related types.

Browser sessions gain optional vaults (VaultReference by id or name) on create and on session responses (including pool acquire and invocation payloads), with links described as immutable after creation. Deleted sessions can expose usage_status (pending | ready).

OTLP destinations now surface delivery health on reads: consecutive_failures, last_export_at, and retained last_error / last_error_at fields with documented semantics.

Config registry list/summary docs and param descriptions shift from domain-level to exact normalized targets (scheme/host/port/path) and latest-analysis recommendations; search is documented as substring search over those targets.

Generated API docs (api.md) and skipped mock-server tests cover the new vault surface; browser create tests include a vaults param example.
