Dashboard users (and other tenant-authenticated admin/operator/owner
actors) dispatching team tasks to agents in Telegram/Discord groups
previously hit the empty-sender DENY rule when the assigned agent
tried to write files — because dashboard users have tenant identities
(e.g. "viettx") that don't match the numeric file-writer grants stored
per channel.
Two-part fix:
1. CheckFileWriterPermission / CheckCronPermission add an RBAC bypass
at the store layer: if ctx carries RoleFromContext in {admin,
operator, owner}, skip the per-user grant check. Tenant RBAC already
pre-authenticated these callers at the gateway edge; requiring a
redundant per-channel grant blocks legitimate admin work.
2. Role propagation through the full dispatch chain:
ctx (RoleFromContext)
→ RunRequest.Role
→ SubagentTask.OriginRole / AnnounceMetadata.OriginRole
/ DelegateRequest.Role
→ InboundMessage.Metadata[MetaOriginRole]
→ subagentAnnounceRouting.Role / teammateRole
→ RunRequest.Role (re-ingress)
→ store.WithRole(ctx, ...) in loop_context
Covers subagent announce, delegate announce, teammate dispatch
(WS dashboard, tool), session_send, and processNormalMessage's
synthetic-sender override path. team_tasks_create persists
origin_role for deferred dispatches.
Viewer and empty roles fall through to the existing sender-based path
(no bypass).
Regression tests:
- A.10 AdminRoleBypass: admin/operator/owner in ctx allowed even with
empty sender (normally DENY).
- A.11 ViewerRoleDoesNotBypass: viewer and empty roles still hit DENY.
Builds + integration + unit tests green.
