fix: wire durable, actor-authorised approval backend for chat channels#2482
Conversation
fixes #2479) Adds PresentationApprovalBackend, a thin ApprovalProtocol adapter wrapping the previously-orphaned PresentationApprovalHandler + SQLite ApprovalStore. It authorises the approver against allowed_actors, persists pending approvals and rehydrates them on restart, binds decisions to an unguessable approval id, and never routes the allow/deny decision through an LLM classifier. Exposed via praisonai.bots and selectable through the CLI --approval secure backend (allowed actors via PRAISONAI_APPROVAL_ACTORS).

This resolver returns PresentationApprovalBackend without a channel_send_func or target. On the CLI/chat approval path, request_approval() forwards those unset values to the handler, the presentation send step is skipped, and tool calls that need approval wait until timeout before being denied.

Reapply actor authorization when rehydrating pending approvals.
rehydrate() currently delegates without passing or restoring self._allowed_actors. The provided handler rehydration context only restores request metadata and target, so approvals restored after restart can lose the allowlist that secured the original request.
Consider extending the handler rehydrate path to persist/restore allowed actors, or have this backend reapply the configured allowlist to rehydrated pending entries before callbacks are accepted.

Fail closed when secure approval actors are not configured.
For --approval secure, a missing or blank PRAISONAI_APPROVAL_ACTORS becomes allowed_actors=None, and the backend documents that None lets any actor resolve approvals. That silently disables the actor-authorization guarantee for the secure path.

There was a problem hiding this comment.
This branch still creates PresentationApprovalBackend without a channel_send_func or target. When an approval is requested from the CLI/chat path, the backend forwards those unset values to PresentationApprovalHandler, the presentation send branch is skipped, and the pending approval waits until timeout before returning approved=False. A user selecting --approval secure never receives a prompt for approval-gated tool calls, so the secure mode cannot be used to approve requests. Please wire the channel delivery function and target into this backend, or fail fast when secure approval is selected without a transport.
