ADR-0023 / Spec.System.PlatformAdministration pins the platform
administrator as a separate identity/session/audit control plane,
intentionally not modeled in alpha (ADR-0025). The legacy
PlatformRoleAssignment / PlatformRole{ADMIN,TEACHER} table had no runtime
reader (no guard, route, or service queried it for an authorization
decision) and ADR-0023 requires it to be replaced before the platform
panel ships.
Drop the model, the PlatformRole enum, the User.platformRoles relation,
and the migration. Stop seeding platformRoles in externalSync principal
ingestion and the integration test helper. Update the doc comments on
OrganizationMembership and PermissionRole to point at the platform-admin
control plane instead of the dropped model.
The 20260709180000_organization_tenant_root backfill only referenced
PlatformRoleAssignment in a one-time INSERT...SELECT; no persistent
object references it, so dropping the table is safe after that migration.
Replace text-only PatchableTextStream with a unified StreamingAgentCard that
renders the full agent run lifecycle in a single Feishu interactive card:
- Tool-use panel: collapsible, shows each tool call with status (running/
success/error), input summary, and result/error in code blocks
- Reasoning panel: collapsible, streams thinking text inline then collapses
on completion
- Answer text: rendered via native Feishu markdown component (no post-row
round-trip)
Runner now captures previously-discarded SDK events:
- thinking_delta → reasoning stream
- tool_use id + input on content_block_start / assistant message
- tool_result from user messages (was entirely unhandled)
New files:
- card/trace-store.ts: per-run in-memory tool-use trace with secret redaction
- card/builder.ts: Feishu card JSON builder (tool panel + reasoning + text)
- card/streaming-card.ts: StreamingAgentCard controller (400ms throttled)
client.ts: add sendCard/patchCard raw JSON primitives
