- H6: batch interface stats query in get_site_capacity_summary, replacing
per-interface SELECT with a single grouped query
- H8: explicit expires_at check in MobileAuth and GraphQLAuth plugs as
defense in depth — the query already filters expired rows, but a future
refactor dropping the filter can't quietly re-enable revoked sessions
- H17: Reports LiveView (toggle/delete/run_now) now uses
Reports.get_organization_report/2 to scope by organization_id, fixing
IDOR where a user could manipulate other tenants' reports by ID
- H18: ToweropsWeb.Api.ParamFilter strips identity fields (id,
organization_id, user_id, created_by_id, inserted_at, updated_at) from
user-supplied API params; applied to devices, sites, checks, and
escalation_policies create/update paths to prevent mass-assignment of
tenant ownership fields if a changeset cast list ever drifts
Performance:
- schedule_live: preload page once instead of get_schedule!/1 per row
- alert_live + alerts: DB-side status filter; Repo.aggregate counts replace length/Enum.count over 500-row fetches on every event
- dashboard_live: drop duplicate get_device_status_counts; cap active alerts to 20 + use count_active_alerts/1
- maintenance.active_windows_for_device: 3 round-trips collapsed into one query (per-site-id branch keeps Postgres parameter types unambiguous)
- sites.build_site_tree: O(N^2) -> O(N) via group_by(parent_site_id)
- accounts.sole_owner_organizations: single group_by + having instead of per-org Repo.aggregate loop
- agents + agent_live (org + admin): count_assigned_devices_batch/1 + count_agent_polling_targets/1 (no preloads)
- alert_digest_worker: list_alerts_by_ids/1 batches digest fetch
- gaiia: distinct: true at DB; limit 50 on bidirectional ilike
Indexes:
- maintenance_windows(organization_id, starts_at, ends_at) WHERE suppress_alerts = true
- alerts(check_id) WHERE resolved_at IS NULL
Antipatterns:
- agents.delete_agent_token: PubSub.broadcast moved outside Repo.transaction so a rollback no longer leaves subscribers acting on a non-existent deletion
- integrations_controller.to_atom_keys: replaced String.to_existing_atom on user-controlled JSON keys with explicit allowlist
- 9 Task.start callsites converted to Task.Supervisor.start_child(Towerops.TaskSupervisor, ...) so background DB writes survive shutdown (test-mode discovery shims left as-is for sandbox semantics)
Extend the GraphQL API and socket to accept mobile session tokens
alongside existing API tokens. Add OrganizationScope middleware
that extracts organization_id from query args for mobile users.
Add my_organizations query for mobile app org listing.
