 | Flow | Source | Destination | Notes |
 |---|---|---|---|
 | Business directive | Manual workbench or AgentBus | Route orchestrator | Source changes input/reply adaptation, not parser or confirmation policy |
+| Manual account authorization | Signed-in account plus resolved business route | Intake and task-transition gates | Administrators hold all routes; team leads/users require explicit grants and unresolved routes fail closed |
 | Parsing | Route orchestrator | AI Skill or deterministic Program parser | AI/Shadow/Auto/Program mode is frozen per task |
 | Operation | Parser | Control-plane task and confirmation | Must validate against the same final contract |
 | ERP execution | Confirmed task | Chrome extension and logged-in ERP page | Requires unique object, page identity, ownership, and write preflight |

 | WeChat roster attachment | Strict transport envelope plus one structured `payload.attachments[]` entry | Existing `awaiting_attachment` task | Explicit conversation ID wins; otherwise strict `Conversation:` supplies the fallback. Placeholder text alone never creates a task. |
 | Internal attachment download | Credential-free HTTPS URL | Bounded in-memory workbook bytes | Internal/private DNS answers are allowed; the selected address is pinned, every redirect is revalidated, and URL/host/IP/bytes are omitted from logs. |
 | Operational diagnostics | Service, request, task, parser, AgentBus, attachment, database, and cleanup stages | Structured stdout/stderr and bounded Docker logs | Correlation identifiers, codes, outcomes, and durations only; no secrets or business payloads. |
+| Operations oversight | Manual task creator, encrypted instruction history, and readable outcome | Team-lead/administrator dashboard projection | Read-only who/instruction/result view; no parser/executor payloads or task mutation authority |
 | Confirmation export | ERP source file | Archived source plus mobile delivery artifact | Visitor XLS becomes real XLSX; other types prefer PDF |
 | Release | Editable source | `dist/release-manifest.json` and versioned artifacts | Manifest owns current hashes and filenames |
 
 ## State Ownership
 
-- PostgreSQL owns durable control-plane task, session, confirmation, channel, audit, and outcome state.
+- PostgreSQL owns durable control-plane account, role, task-route grant, task, session, confirmation, channel, audit, archive, and outcome state.
 - Production attachment bytes use the configured OSS provider; normalized sensitive fields remain encrypted.
 - Chrome extension local state is bounded execution/reconciliation support, not canonical business history.
 - `.project-docs/30-worklog/tasks/` owns task-local project memory; canonical project state is an integrated projection.
