Prefix fire-and-forget calls (PubSub.broadcast, Oban enqueue, Logger,
update_*, etc.) with `_ =` so dialyzer knows the return value is
intentionally discarded. Wrap a few if/case expressions whose
branches produce mixed types the same way.
No behavior changes — only explicit acknowledgement of discarded
returns.
Warnings: 242 → 88.
This commit addresses multiple CRITICAL, HIGH, and MEDIUM severity security vulnerabilities identified in the security audit:
CRITICAL FIXES:
- Fix weak RNG for recovery codes - replaced Enum.random() with :crypto.strong_rand_bytes/1 for cryptographically secure token generation
- Fix subscription limit race conditions - moved free org and device quota checks inside transactions with FOR UPDATE locks to prevent concurrent bypass
- Fix default organization race condition - moved is_default check inside transaction to prevent multiple defaults per user
HIGH SEVERITY FIXES:
- Fix agent token deletion race condition - moved PubSub broadcast inside transaction to ensure agents only receive notification after successful deletion
MEDIUM SEVERITY FIXES:
- Fix LIKE wildcard injection in search - applied sanitize_like() to all user-facing search queries in devices.ex, sites.ex, and gaiia.ex to prevent enumeration attacks
- Fix Jason.decode! DoS - replaced with safe Jason.decode/1 with error handling in device_live/index.ex
- Fix SSRF vulnerability - added URL validation in HTTP executor to block requests to private/internal IP ranges (127.0.0.0/8, 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16, 169.254.0.0/16)
- Fix error information leakage - replaced inspect() in API responses with generic error messages, logging details server-side only
- Fix atom table pollution - HTTP method normalization now uses whitelist mapping instead of String.to_atom()
SECURITY IMPROVEMENTS:
- All quota checks now use pessimistic locking (SELECT FOR UPDATE) to prevent TOCTOU race conditions
- Private IP validation prevents cloud metadata service access (169.254.169.254)
- DNS resolution performed before HTTP requests to detect IP spoofing
- Error details logged server-side but not exposed to clients

Set up mix_gleam archive, gleam_stdlib, and gleeunit deps. Add Gleam
compiler to all Dockerfiles, CI workflows, nix shell, and .tool-versions.
Rewrite Numeric, QueryHelpers, and URLValidator from Elixir to Gleam with
full ExUnit test coverage. Update all callers to use the Gleam modules
directly via :towerops@module syntax. Remove duplicate sanitize_like/1
private functions in snmp.ex and trace.ex.

Shows a red badge on the bell icon with the unresolved alert count.
Displays the number when <= 100, blank red dot when > 100 (Apple-style).
Count is loaded at mount and updated live when alerts change via PubSub.
Uses process dictionary pattern (same as cookie consent) so no template
changes needed across the 41 LiveView layouts.
Dynamically update page title emoji when device/alert status changes:
- Add PubSub broadcasts when alerts are created/resolved
- Create StatusTitleComponent LiveComponent to subscribe to alert changes
- Add StatusTitle JavaScript hook to update document.title in real-time
- Subscribe to organization:alerts channel on LiveView mount
- Push emoji update events when alert status changes
This provides immediate visual feedback in browser tabs when
critical/warning/healthy status changes without requiring page refresh.
When the Oban queue backs up, the 60-second uniqueness window expires
and duplicate jobs stack up per device. Switch to period: :infinity so
only one poll/monitor job exists per device at any time. Add replace
option to supersede stale scheduled jobs with updated scheduled_at.
Remove :executing from unique states so self-scheduling works while
the current job runs. Set max_attempts: 1 since retrying stale polls
is pointless.
Also fix all credo --strict issues across the codebase.
New role system:
- owner: full access + financials
- admin: full access + financials (except org deletion)
- executive: read-only + full financial visibility (MRR, revenue)
- technician: field ops (devices, sites, alerts) without financials
- member: legacy alias for technician (migrated)
- viewer: read-only, no financials
Financial data (MRR, revenue, billing) gated behind can_view_financials
assign in all LiveView templates: dashboard, alerts, trace, site show.
Includes migration to rename existing member roles to technician.
CRITICAL fixes:
- Mask SNMP community string in agent channel logs (CRITICAL-1)
- Remove snmpv3 passwords from REST API responses, return _set booleans (CRITICAL-2)
- Replace snmp_community with snmp_community_set in GraphQL type (CRITICAL-3)
HIGH fixes:
- Fix cookie same_site from invalid 'Towerops' to 'Lax' (HIGH-4)
- Remove unsafe-eval from CSP script-src (HIGH-6)
- Block GraphQL introspection queries in production (HIGH-7)
- Sanitize LIKE wildcards in SNMP device name search (HIGH-8)
- Reject webhooks when no secret configured instead of accepting (HIGH-9)
MEDIUM fixes:
- Hash mobile session tokens (SHA-256) before DB storage (MEDIUM-10)
- Apply security headers in all environments, not just prod (MEDIUM-14)
- Add GraphQL query complexity limit (500) in production (MEDIUM-16)
- Fix X-Frame-Options to DENY to match frame-ancestors 'none' (MEDIUM-13)
Previously redirected to /dashboard or /orgs based on whether the
superuser had organizations. Now always goes to /devices for
consistency.

Migrates all admin-related flash messages to gettext for internationalization:
- Admin.UserLive.Index: user deletion messages
- Admin.OrgLive.Index: organization deletion messages
- UserAuth: impersonation start/stop messages
Adds Gettext backend and helpers import to UserAuth module to support translations.
All admin and auth tests passing (87 tests).
- Add UserSudoController with GET and POST /users/sudo/verify routes
- Create verify.html.heex template for TOTP verification form
- Only accept TOTP codes (6 numeric digits), reject recovery codes
- Update grant_sudo_mode to set authenticated_at virtual field
- Exclude /users/sudo paths from return_to overwriting
- Add comprehensive controller tests (12 test cases)
- Verify redirect behavior, error handling, and session management

- Created new on_mount hook :load_default_organization that automatically loads user's first organization
- Moved sites and devices routes to root path (/ sites, /devices) instead of /orgs/:org_slug
- Updated all navigation links and route references throughout the app

- Users can still switch organizations via org selector for other pages
- Add timezone to socket assigns in mount_current_scope

- Auto-save detected timezone to user profile on first connection
- Update all templates to use TimeHelpers with timezone parameter
- Update agent helper functions to accept timezone parameter
- Templates updated:
- Alert list (triggered, acknowledged, resolved)
- Device list (last checked)
- Agent list and show (created, last seen, updated)
- Admin dashboard (impersonation logs)
- Admin org/user lists (created/joined dates)
- Main dashboard (alert times)
- Update user settings page to use Tailwind Plus 3-column grid layout
- Add API token management section to user settings
- Implement organization name display in navigation menu
- Update table component to use Tailwind Plus styling across all tables
- Update flash notifications with Tailwind Plus design

- Add store_return_to_for_liveview plug to browser pipeline
- Add profiles.json to gitignore
- Create UserSettingsLive to replace UserSettingsController
- Convert email/password forms to LiveView with proper form handling

Users now go directly to their intended destination after clicking a
magic link, with no interruption for "log in and stay logged in" choice.
When exiting impersonation, now redirects to the superuser's default
organization's equipment list page instead of /admin. Falls back to /orgs
if the superuser has no organizations.
