fix(admin): apply role disconnect policy changes to existing node users

[dr-hoseyn]

Summary

Editing a role's disconnect policy previously saved the policy without updating its existing node users. Apply the requested policies to active/on-hold users of disabled or limited admins, scoped to the affected role and admin statuses.

Load users with ID-based pagination in batches of at most 500 and await each batch's dispatch before loading the next. The role-edit path surfaces dispatch errors; existing background callers retain their behavior. Explicit policy fields reconcile even when their values are unchanged, so resubmitting the same request recovers lookup, serialization, or dispatch failures after the policy commit. Edits that omit both policy fields do not query or dispatch users.

User/admin statuses and per-admin max_users limits are unchanged.

Type of change

• Bug fix

Checklist

• Tested locally.
• Added or updated committed tests. Regression checks were run locally; test files are intentionally excluded.
• No documentation, translations, or examples need changes.
• No model/schema changes or migrations.
• No secrets or unrelated changes.

Testing

• 191 passing checks across existing admin-role, admin, node API, node synchronization, manager synchronization, and preemption suites, plus local regression checks.
• API checks exercise both policy directions for disabled and limited admins, including identical-request retries after committed lookup, serialization, and dispatch failures.
• Local checks inject failures after the first successful batch, including request cancellation; retries replay every eligible user safely. Also checked dispatch backpressure, enqueue failure propagation, split-role publication, and omitted-policy edits.
• Large SQLite fixture: 900 admins, 4,500 users, and 13,500 history rows. The 600 affected users are dispatched in batches of 500 and 100 using 7 SQL queries, with no history objects loaded.
• Ruff lint/format and git diff --check passed.

Screenshots

Not applicable.

Notes for reviewers

Only five production files change; no test or documentation files are included. Recovery uses idempotent reconciliation on retry, without a schema change or outbox. It does not add remote node acknowledgement guarantees; split-role dispatch waits for NATS publication. Existing delivery-time current-state refresh remains in place.

Walkthrough

Role modification now detects changes to limited- and disabled-admin blocking policies. It loads users associated with the affected role and admin statuses, then removes or synchronizes those users according to the updated policies.

Changes

Role Policy Synchronization

Layer / File(s)	Summary
Role-scoped node-sync user lookup app/db/crud/user.py	The shared node-sync loader accepts an admin predicate and optional user statuses. The new role lookup selects users for matching admins and loads active and on-hold users.
Policy transition synchronization app/operation/admin_sync.py, app/operation/admin_role.py	Role modification records the prior blocking policies and calls the transition synchronizer after committing. The synchronizer looks up affected users and removes or syncs them based on the updated policies.

Merge Risk: 🟡 Moderate · up to 0ad12

Editing a role's disconnect policy now loads and pushes every affected user in a single request. For large roles this can use a lot of memory and slow down or time out the role edit. If the node update fails after the change is saved, resubmitting the same settings will not retry it. Users can then stay connected or disconnected contrary to the saved policy. Both issues should be addressed or explicitly accepted before merging.

_{A rabbit checks the role settings with care,
Then finds the users linked to them there.
If blocking policies shift their place,
Users are removed or synced in pace.
The rabbit hops off, with a neat update to share.}

load eligible users and dispatch them in bounded batches instead of
materializing and serializing the full role-wide result before dispatch; keep
max_users’ existing per-admin behavior unchanged.

Review comments at @app/operation/admin_role.py:
- Line 88: Update the role-change flow around
sync_role_users_for_block_transition so failures after db.commit() leave
synchronization recoverable on retry; persist retryable work with the role
change or provide an idempotent reconciliation path that requeues the missed
node update even when a retry detects no policy transition.

Thanks for this, the gap was real. I pushed one commit on top of your branch:

• The dashboard sends both disconnect fields on every role save, so reconciling every explicitly sent field re-sent the role's blocked users on every save, even a rename. With one unreachable node registered, the save returned 500 after the change was already committed, and a slow node held the request open for every batch.
• Now only an actual policy change dispatches, and the reconciliation runs after the response with its own session. It re-reads the role under a per-role lock, so overlapping edits end in the latest policy. Your ID-paged batches and awaited dispatch are kept.
• Per-node failures are logged instead of raised. A node that misses a batch gets a fresh snapshot (which already excludes blocked admins' users) when it reconnects.

Tests are in tests/api/test_admin_role_policy_sync.py.
