- /insights now shows a "Regenerate insights" button for superusers
that enqueues all seven insight workers (Preseem baselines,
capacity, device-health, Gaiia, system, wireless, LLM enrichment).
Non-superusers neither see the button nor can trigger the event.
- Dialyzer is clean: added :tools to plt_add_apps, gave
Preseem.Insight a @type t, pinned a few unmatched returns, and
suppressed a known MapSet opaque false-positive in Towerops.Unused.
- e2e: NODE_OPTIONS=--disable-warning=DEP0205 silences the Node 25
deprecation noise from Playwright's internal ESM loader.
Add PromEx with Application/BEAM/Phoenix/LiveView/Ecto/Oban plugins plus
a custom plugin that bridges existing Towerops Oban/Redis telemetry events.
The metrics HTTP server runs isolated on port 9568 so scrape traffic never
traverses the public Traefik IngressRoute.
The pod template carries prometheus.io annotations (scrape, port, path, job)
so the external Prometheus on 10.0.15.31 discovers each pod through the
existing kubernetes-pods scrape job (apiserver-proxy).
Dialyzer:
* Add Lidar.Tile @type, narrow several @specs to match success-typing,
prefix discarded function returns with `_ =`, fix the broken
File.stream! call in the ms-buildings worker (it was causing dialyzer
to mark every private fun unreachable), broaden Antenna.spec key
types from `float()` to `number()` to match catalog int literals.
* Add :geo, :geo_postgis, :db_connection to plt_add_apps so the dep
PLT actually contains the modules we use.
* Result: 0 unsuppressed dialyzer warnings (was 50+ in project code).
Tree canopy:
* Replace the dead landfire.gov URL with the ETH Zurich Global
Canopy Height 10 m product. ETH publishes proper COGs with
overviews on libdrive.ethz.ch — confirmed working with
/vsicurl/ byte-range reads. The module now picks the 3°×3° tile
containing the bbox centroid, with both a `:metres` decoder
(ETH Byte raster, NoData=255) and a `:landfire_evh` decoder for
operators self-hosting LANDFIRE EVH COGs.
* Re-enable canopy by default now that there's a working source.
Tests (+105 tests, 0 failures):
* CoverageLive Index/Show/Form/Map — empty/loaded/auth states,
LiveView event handlers, formatters.
* Coverages.Building changeset + helpers.
* Coverages.TreeCanopy provider tile-URL builder and decoders.
* Workers.MsBuildingsImportWorker (full import flow incl. blank
lines, MultiPolygon, idempotency, hash fallback) — also fixed
the partial-index ON CONFLICT bug that prevented imports from
ever working: the unique index has WHERE ms_footprint_id IS
NOT NULL, so the worker now uses an :unsafe_fragment conflict
target that includes the predicate.
* GraphQLDocsController smoke test (was 0%).
Coverage rose from 73.19% → 74% with the major project modules I
touched all moved from 0% / <50% to >75%.
Catalog-only system for LIDAR-derived 1m DEMs covering Texas. We do not
mirror raster data — the DB stores tile metadata (URL + footprint
geometry) and elevation values are streamed on-demand from public USGS
3DEP / TNRIS Cloud-Optimized GeoTIFFs via GDAL /vsicurl/ HTTP byte-range
reads. Used for future tower coverage line-of-sight calculations.
- Enable PostGIS extension; tile footprints indexed via GiST
- Catalog sync from USGS 3DEP (primary) and TNRIS (fallback for gaps)
- Tile dedup by ST_Contains so TNRIS doesn't duplicate 3DEP coverage
- Single-point reads via gdallocationinfo with tile fallthrough on nodata
- Grid retrieval via gdal_translate AAIGrid with multi-tile mosaicing
- Monthly Oban cron worker keeps catalog fresh
- gdal-bin added to runtime image; geo_postgis dep added
Bumps vendored Oban Pro from 1.6.13 to 1.7.0, which transitively bumps
oban core to 2.22.1 (requires migrations v14) and db_connection to 2.10.0.
- mix.exs constraint: ~> 1.6 → ~> 1.7
- vendor/oban_pro/ replaced with v1.7.0 hex package
- migration 20260430142200: Oban core v12 → v14 (must run first)
- migration 20260430142241: Oban Pro 1.7.0 schema additions
Also corrects a pre-existing constraint name in AgentAssignment that was
left stale by the equipment→devices rename migration (20260117190134).
The unique index is named agent_assignments_device_id_index, but the
schema's unique_constraint/3 still pointed at the old equipment_id name,
causing the test suite to surface Ecto.ConstraintError instead of a
changeset error. Required to get the suite green for this upgrade.
Promoted pure presentation and utility helpers from `defp` to `def @doc false`
across ~20 LiveViews, Oban workers, and sync modules so they're reachable from
unit tests. Refactored several `cond` blocks into idiomatic function heads with
guards. Added ~250 new test cases in new files under test/towerops and
test/towerops_web, including DB-backed tests for CnMaestro.Sync and
AlertNotificationWorker, and removed dead LiveView tab components and
CapacityLive (no callers anywhere in lib/test).
Configured mix.exs test_coverage.ignore_modules to exclude vendored third-party
code (SnmpKit, protobuf-generated Towerops.Agent.*, Absinthe GraphQL types,
Phoenix HTML modules, Inspect protocol impls) from coverage calculations —
these are not our project code.
Coverage: 66.93% → 70.09%. Full suite: 10,127 tests, 0 failures.
Ignore file was silencing every warning under lib/towerops/**. Root
cause was plt_add_deps: :apps_direct missing Plug/Phoenix/Oban/Decimal
/Redix/ssl/public_key — hundreds of false `unknown_function` warnings
were being papered over.
Expand plt_add_apps to cover the common deps, narrow the ignore file
to real dep-PLT gaps only, and fix two concrete bugs uncovered by the
change:
- ScopedResource.fetch_preload/4: spec was atom() | [atom()] but
callers pass keyword lists (e.g. [rules: :targets]).
- ToweropsNative: tag NIF stubs with @dialyzer :nowarn_function so
dialyzer trusts the @spec instead of the fallback body.
Remaining 328 real warnings surface for follow-up.

Replace the protobuf hex package (agent.pb.ex) and hand-written validator
(validator.ex) with a pure Gleam implementation: wire format primitives,
all 23 message types, encode/decode functions, and validation merged into
decode. Thin Elixir wrappers in agent.ex preserve the existing struct API.
- Wire format: varint, length-delimited, double (IEEE 754 via FFI), tag encode/decode
- Types: all proto3 message types as Gleam custom types with enums and oneof
- Decode: field-level parsing with integrated validation (UUID, IP, hostname, limits)
- Encode: proto3 default omission, bytes_tree concatenation, map/repeated fields
- Wrappers: Elixir structs with encode/decode delegating to Gleam, enum atom conversion
- Remove {:protobuf, "~> 0.12"} dependency

Migrate three pure-function modules from Elixir to Gleam:
- polling_offset: deterministic hash-based polling offset (pure Gleam, no FFI)
- changelog_parser: text parsing logic in Gleam, thin Elixir wrapper for File I/O
- user_agent_parser: regex-based UA parsing in Gleam with Erlang FFI for
atom-keyed map conversion
Add gleam_regexp dependency for regex support in Gleam modules.
Update all call sites and tests to use Gleam module atoms.

Add castore as a direct dependency to provide CA certificates in
environments where the OS trust store is not available (Dokku staging).
Stop leaking raw system errors (like CA trust store details) to the
UI by logging the full error server-side and showing a generic
user-friendly message instead.
- Add error_tracker_notifier for email alerts on exceptions
* Sends alerts to graham@towerops.net
* Configured in production only (gracefully shuts down in dev/test)
* Includes throttling to prevent duplicate error spam
- Fix AlertNotificationWorker when PagerDuty not configured
* Worker now handles :not_configured gracefully instead of failing
* Prevents unnecessary retries and error noise
* Logs as debug when PagerDuty integration isn't set up

The test alias was prompting 'Are you sure you want to proceed?' when
the database structure was already loaded, requiring manual confirmation
on every test run.
Add --skip-if-loaded flag to ecto.load command so it silently skips
structure loading if schema_migrations table already exists.
Now 'mix test' runs without user interaction.
Replace sequential migration execution (4m8s for 172 migrations) with
structure.sql loading (416ms), reducing CI database setup time by 99.7%.
Changes:
- Configure Ecto to dump/load schema from priv/repo/structure.sql
- Update test alias: ecto.migrate → ecto.load
- Remove redundant database setup step from CI workflow
- Commit structure.sql to repository for version control
Benefits:
- CI database setup: 4m8s → 416ms (248s → 0.4s)
- Consistent schema snapshots across environments
- Faster local test runs
Maintenance:
- Run 'mix ecto.dump' after adding new migrations
- Structure file auto-updates with schema changes
Replace the HoneybadgerNoticeFilter that emailed raw stacktraces on
every exception with ErrorTracker for self-hosted error tracking.
Honeybadger itself is retained. ErrorTracker dashboard is mounted at
/admin/errors behind the superuser auth wall.
- Replace terse helper text with step-by-step setup guide in config form
- Add what-gets-synced breakdown when PagerDuty is enabled
- Clear visual hierarchy with numbered steps and inline callout
Changes:
- Fix traffic graph to handle nil interface octets gracefully
- Add comprehensive tests for nil octets scenarios
- Fix agent polling query to support devices assigned directly to org (left join on sites)
- Fix test SNMP connection to inherit credentials from site/org
- Refactor agent_channel process_polling_result to reduce nesting (Credo)
- Add alias for JobCleanupTask in application.ex (Credo)
This fixes crashes when interface stats have nil octets and ensures
devices without a site assignment can be polled by agents.

Add explicit 'make' step in Dockerfile to compile the C NIF before
Elixir compilation. This ensures towerops_nif.so exists when the
Elixir code tries to load it.
The custom compiler task creates a bootstrap problem (needs to be
compiled before it can be used as a compiler), so we compile the
C NIF explicitly instead of relying on the compilers list.
Replaces etcd-based distributed locking with Oban's PostgreSQL-backed job queue.
This simplifies the architecture by eliminating the need for a separate etcd cluster
while providing better reliability and observability.
Changes:
- Add Oban dependency and migration (oban_jobs table)
- Create DevicePollerCoordinator and DeviceMonitorCoordinator Oban workers
- Remove EtcdCoordinator and EtcdLock modules
- Update application supervisor to start Oban
- Configure Oban with pollers (50 workers) and monitors (50 workers) queues
- Remove etcd StatefulSet from Kubernetes manifests
- Update monitoring supervisor documentation
Benefits:
- Simpler architecture (no etcd cluster to manage)
- PostgreSQL-based (uses existing database)
- Built-in uniqueness prevents duplicate jobs cluster-wide
- Better observability with Oban Web UI
- Automatic job rescue on node crashes
- Easier local development (no etcd required)
What was removed:
- etcd StatefulSet (3 pods)
- EtcdCoordinator module (320 lines)
- EtcdLock module (158 lines)
- eetcd dependency
All 3,686 tests passing.
