Some checks failed
Build and Push / Build and Push Docker Image (push) Has been cancelled
Rows left behind by a crashed/killed prior run persist because sandbox on_exit callbacks don't fire on BEAM crash or SIGKILL. Wipe known test-data tables (contacts, hrrr_fetch_tasks, iemre_observations, oban_jobs) after app boot so every suite starts clean regardless of previous run state.

# lazy_html provides an Enumerable protocol implementation for the

# LazyHTML struct. When protocol consolidation is enabled (the default),

|
# the consolidated Elixir.Enumerable.beam file is generated during
|
|
# `mix compile`. If that consolidation pass runs before lazy_html is on
|
|
# the code path, the dispatch table omits LazyHTML — causing every test
|
|
# that uses Phoenix.LiveViewTest (which calls Enum.each/2 on LazyHTML
|
|
# structs via DOM.parse_document/2) to crash with:
|
|
#
|
|
# (Protocol.UndefinedError) protocol Enumerable not implemented for
|
|
# LazyHTML (a struct)
|

# mix.exs disables `consolidate_protocols` in the test environment so
|
|
# the protocol uses dynamic dispatch instead, which always finds the
|
|
# Enumerable.LazyHTML implementation at runtime.
|
|
|
|
# Silence sandbox-cleanup disconnect noise. When a test process exits
|
|
# while still owning a Postgrex connection, the protocol logs an
|
|
# `[error] Postgrex.Protocol ... disconnected: ... client #PID<...>
|
|
# exited`. It's benign — the connection is being torn down on purpose
|
|
# — but at :error level it bypasses `capture_log: true` (which only
|
|
# captures logs from the test process). Pinning these modules to
|
|
# :critical drops the noise without affecting real DB error logging.
