Feishu approval clicks need the resolved card to come back from the
synchronous callback path itself. Leaving approval resolution to the
generic asynchronous card-action flow made button feedback depend on
later loop work instead of the callback response the client is waiting
for.
Change-Id: I574997cbbcaa097fdba759b47367e28d1b56b040
Constraint: Feishu card-action callbacks must acknowledge quickly and reflect final approval state from the callback response path
Rejected: Keep approval handling on the generic async card-action route | leaves card state synchronization vulnerable to callback timing and follow-up update ordering
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Keep approval callback response construction separate from async queue unblocking unless Feishu callback semantics change
Tested: pytest tests/gateway/test_feishu.py tests/gateway/test_feishu_approval_buttons.py tests/gateway/test_approve_deny_commands.py tests/gateway/test_slack_approval_buttons.py tests/gateway/test_telegram_approval_buttons.py -q
Not-tested: Live Feishu workspace end-to-end callback rendering
Add button-based exec approval to the Feishu adapter, matching the
existing Discord, Telegram, and Slack implementations.
When the agent encounters a dangerous command, Feishu users now see
an interactive card with four buttons instead of text instructions:
- Allow Once (primary)
- Allow Session
- Always Allow
- Deny (danger)
Implementation:
- send_exec_approval() sends an interactive card via the Feishu
message API with buttons carrying hermes_action in their value dict
- _handle_card_action_event() intercepts approval button clicks
before routing them as synthetic commands, directly calling
resolve_gateway_approval() to unblock the agent thread
- _update_approval_card() replaces the orange approval card with a
green (approved) or red (denied) status card showing who acted
- _approval_state dict tracks pending approval_id → session_key
mappings; cleaned up on resolution
The gateway's existing routing in _approval_notify_sync already checks
getattr(type(adapter), 'send_exec_approval', None) and will
automatically use the button-based flow for Feishu.
Tests: 16 new tests covering send, callback resolution, state
management, card updates, and non-interference with existing card
actions.
