## Summary
- **DB pool exhaustion**: `device_has_effective_agent?` was doing 2 DB queries per call (3-table join + global settings lookup), called 2-3x per worker cycle across hundreds of devices (~6000 unnecessary queries/minute). Added an ETS-backed `AgentCache` with 120s TTL and removed redundant calls within the same worker cycle.
- **Settings page crash**: `KeyError: key :user_agent not found` on BrowserSession — field doesn't exist, replaced with `device_type`.
- **Login history IP truncation**: Changed from side-by-side grid to stacked table layout so IP addresses aren't clipped.
## Test plan
- [x] 8 new tests for AgentCache (cache hit, miss, invalidation, global default)
- [x] Full test suite passes (8651 tests, 0 failures, verified across multiple runs)
- [x] `mix format` and pre-commit hooks pass

- Add "Agent:" label before the agent indicator for all states
- Fix TimeSeriesTest deadlock: switch to async: false since check_results
is a TimescaleDB hypertable and concurrent chunk creation deadlocks
- Fix unicode property test: String.length/1 counts grapheme clusters,
not code points; combining chars can make a 2-codepoint string have
only 1 grapheme, legitimately failing the min: 2 validation

## Summary
- **DNS checks**: `parse_server` returned a flat 5-tuple `{a,b,c,d,53}` instead of `{{a,b,c,d}, 53}` — the format `:inet_res` requires for nameservers. All DNS checks using a custom server failed with argument error.
- **Ping checks**: `System.cmd` `:timeout` option not supported on Elixir 1.19.4 (staging). Replaced with `Task.async`/`Task.yield` wrapper for cross-version compatibility.
- **Checks table UI**: Removed unnecessary flex div wrapper on status badge column that caused vertical misalignment with other table cells.
## Test plan
- [x] DNS executor tests pass (custom server resolution now succeeds)
- [x] Ping executor tests pass (no more ArgumentError)
- [x] Full test suite passes (8593 tests, 0 new failures)

## Summary
- Every device now automatically gets an ICMP ping check (`source_type: "auto_discovery"`) when created via `Monitoring.ensure_default_ping_check/1`
- When a device IP changes, the ping check host config is synced automatically
- Backfill migration inserts ICMP Ping checks for all existing devices that don't have one
- Fixes checkbox alignment in the Add Service Check modal (verify SSL / follow redirects)
## Test plan
- [x] 4 new tests for `ensure_default_ping_check/1` (create, idempotent, IP update, no-op)
- [x] 3 new tests for device lifecycle (auto-create on device create, sync on IP change, no-op when IP unchanged)
- [x] 13 existing tests updated to account for auto-created ping check
- [x] Full test suite passes (`mix precommit`)
- [ ] Verify backfill migration on staging
- [ ] Create device in UI, confirm ping check appears in service checks list
- [ ] Verify checkbox alignment in Add Service Check modal

## Summary
Hide RF link-related UI elements from the network map page while keeping all backend code intact.
### Changes
- Commented out "View RF Links" button in network map node detail panel
- Commented out RF Link health legend (Good signal / Degraded / Critical) from map legend
- Backend topology.ex code untouched — `compute_rf_link_stats/1` and `enrich_edges_with_rf/2` remain
- No RF tab exists on the device show page, so no changes needed there
### Verification
- `mix compile --warnings-as-errors` — zero warnings
- `mix test` — 8490 tests pass, 0 failures

The StormDetector was being added twice:
1. In the main children list (line 127)
2. In background_workers() (line 176)
This caused the supervisor to fail with 'duplicate_child_name' error.
Removed the duplicate from main children list since it's correctly
placed in background_workers() which also handles test env properly.

When alert routing is set to "builtin" (TowerOps) but no escalation
policy exists, the checklist item now reads "Create an escalation
policy" and links directly to the new escalation policy page instead
of looping back to general settings where the routing already looks
configured.
The sync schedule was shown twice on non-exclusive integration cards
(inline status row + separate box). Remove the box to match the
uniform inline display used by the billing card.
Adjust sidebar bottom section padding from py-3 to py-3.5 to align
the horizontal border with the footer border. Also remove unused
private functions from settings_live and fix credo warnings.
- Replace inline integrations tab with link to /settings/integrations
- Remove ~1500 lines of duplicated integration UI from settings
- Remove duplicated integration event handlers from settings_live
- Standalone IntegrationsLive page remains the single source of truth
- Settings page down from ~2400 to ~900 lines
- Setup Progress bar on dashboard when devices exist but setup incomplete
- Tracks: devices added, billing connected, alert routing configured,
on-call schedule created
- Each step links to the relevant setup page
- Dismissible with X button
- Progress bar shows visual completion percentage
- Optional steps labeled (billing, on-call)
- New 'alert_routing' field on organizations (default: builtin)
- AlertNotificationWorker respects the setting:
- builtin: only built-in escalation policies
- pagerduty: only PagerDuty events
- both: fire both (useful during migration)
- Radio button UI in Settings → General with visual cards
- Warning shown when PagerDuty selected but not configured
- Migration, schema validation, 6 tests

- Make unlinked AP rows clickable to open linking panel
- Make IP addresses clickable http links
- Improve linking row layout and descriptive copy
- Replace bare dash with "Not linked" pill in Linked Device column
The linking row was rendered in a separate loop after all device rows,
causing it to always appear at the bottom of the table. Changed to use
a single for loop with an inline if check so the linking row appears
immediately after the corresponding device row.
- Hide less-critical table columns on small screens (IP, subs, MRR, etc.)
- Add overflow-x-auto wrappers on tables to prevent horizontal scroll

Update Gaiia integration links on settings and integrations pages to match
the names already used on the mapping page itself: "Device & Site Linking"
and "Comparison Report".
Add an Appearance section to the Personal tab in user settings with
three clearly labelled options (Auto/Light/Dark). A ThemeSelector hook
reads localStorage to highlight the active choice and updates it when
selection changes. Remove the dropdown toggle from both the main nav
and admin nav.
When saving new or updated API credentials, reset last_sync_status to
"never" and clear last_sync_message and last_synced_at so stale error
messages from previous syncs don't persist in the UI.
All non-NetBox provider forms (Sonar, Splynx, Gaiia, Preseem, PagerDuty,
VISP) had the same bug as NetBox: credential inputs used value= bindings
reading from saved DB state. Any phx-click event (Test Connection, etc)
triggering a re-render would wipe unsaved typed values.
Fix by adding @integration_credentials assign, initialized from saved
integration when opening config and updated from form params on every
phx-change via validate_integration.
Sync direction button clicks (phx-click) triggered a LiveView re-render
that reset the url and api_token inputs to their saved DB values, wiping
any unsaved typed text. Fix by tracking url and api_token in @netbox_config
so they survive click-triggered re-renders.
