- TimeHelpers.to_datetime: `cond` with match?/2 guards becomes five
function heads dispatched by input type — DateTime passes through,
NaiveDateTime anchors to UTC, integer is a millisecond Unix epoch,
binary tries ISO 8601, everything else is nil.
- PageController.health: the three-branch `cond` + inner `if db_healthy`
becomes a chain of small respond_* helpers, each pattern-matched on a
single axis (health_status, shutting_down?, db_healthy?). db_healthy?/0
isolates the rescue.
- format_uptime splits the cond into four format_uptime_parts/4 clauses.
Adds tests for the PageController actions (health 200 / 503-draining,
ready, sitemap.xml, .well-known/api-catalog, status.json). Coverage
66.81 → 67.29%.
- Add @spec annotations to all public functions in time_helpers.ex
- Add @spec annotations to all public functions in weather_units.ex
- Add @spec annotations to authentication functions in user_auth.ex
- Fix User struct type reference (use %Aprsme.Accounts.User{} instead of t())
- All dialyzer checks now pass successfully
These type specifications improve code documentation and enable better
compile-time type checking with dialyzer.
