AHP Swift Package v1.0.0

[1.0.0] — 2026-10-02

Implements AHP 1.0.0.

Added

• AuthenticateParams.expiresIn carries an OAuth access token's remaining lifetime in seconds.
• SessionSummary.chats, SessionChatSummary.interactivity, and SessionSummary.defaultChat expose lightweight chat navigation data without requiring a session subscription.
• chat/isArchivedChanged action for archiving a chat independently of its session.
• ChatState.changesets and chat/changesetsChanged expose each chat's changeset catalogue through the subscribed chat channel.
• AutomationDefinition.disableConditions supports afterRuns (max) and afterDate (date) rules combined with logical OR, with at most one condition per kind. Host-owned AutomationEntry.runCount tracks the current scheduled-run allowance. Edit conditions through automation/updateRequested: omission leaves them unchanged, an array replaces them, and [] removes all conditions without re-enabling the automation.
• ChangesetStatus.Recomputing distinguishes refreshes of a completed result from initial changeset computation.
• ConfigPropertySchema.minItems and ConfigPropertySchema.maxItems express array cardinality for type: "array" config properties. (#432)
• McpServerStartingState.blocking flag indicating that message processing may be held on the server, and the client-dispatchable session/mcpServerBackgroundRequested action asking the host to background such a startup.
• AutomationSessionTemplate.customizations lets automations carry client plugins (skills, agents, prompts, rules) that the host captures when the definition is saved, with the host-owned copies reported in AutomationEntry.customizations and support advertised by AutomationCapabilities.customizations.
• Hosts can advertise chat-owned canvas channel references and synchronize live presentation metadata and source URLs on experimental per-canvas channels.
• Atomic stable-URI moveChat transfer and same-session ordering for host-authorized chats, with per-chat movable discovery and durable authoritative catalogs.
• Expose chat-owned background work (background shells and subagents) in chat state, with chat/backgroundWorkSet and chat/backgroundWorkRemoved actions independent of turn lifetime.
• ChatSummary.changes and ChatState.changes provide aggregate file-change counts without requiring a changeset subscription.
• SessionChatSummary.status exposes per-chat archived state via SessionStatus.IsArchived in the lightweight chat catalog without requiring a session subscription.
• chat/isReadChanged action and optional SessionChatSummary.status projection for independently tracking the status of any known chat, including the default chat; the status bitset replaces the unreleased isRead and archived catalog fields.
• SessionChatSummary.changes exposes per-chat change counts in the lightweight chat catalog without requiring a session subscription.

Changed

• Historical ToolResultTerminalContent.resource subscriptions return lazily reconstructed exited terminal state with retained output.
• FileEdit and preview edits now use named models in generated SDKs. This breaks affected SDK APIs but keeps JSON shapes unchanged.
• Advertise only the 1.0.0 and 0.9.0 protocol compatibility baselines independently of the development version. Host-side negotiation helpers select the highest client-offered version within either caret-compatible range and report malformed offers explicitly.
