NaN is a number, so the type guard admits it, and every comparison
against NaN is false, so neither clamp catches it and the function
returns NaN.
Left unguarded on purpose. No caller can produce it: parse() matches
%d+ for the sun times and `now` is os.time(). If one ever did, Cairo
ignores a NaN coordinate, so the arc would lose its dot rather than the
dashboard going blank. A ponytail: comment names the ceiling and where
the guard would go.
Found while probing the committed code, not by the tests, which do not
cover NaN.

Two comments, no behaviour change.
`force - 1` reads as an off-by-one until you know the scale starts at 0
while ipairs starts at 1, so the loop index is already force + 1. Said
plainly now, along with why the fall-through returns 12.
compass() has no caller: the card draws arrow(). It is kept because it
shares arrow()'s binning exactly, so testing both pins that shared logic
from two angles, and switching the card to "S 9 km/h" becomes a one-word
change. Without this note the next reader finds an unused function and
has to reconstruct the reasoning.
Raised by code review as the only two points worth acting on; no
Critical or Important issues were found.

icon(800, nil, 1500, 1900) compared nil against a number and raised,
which in this project is a blank dashboard with no message. The module's
own header promises nothing raises, and is_day() already guards the same
case, so the inconsistency was the bug.
Not reachable from the widget as written: it passes os.time(), and
parse() refuses a response without sunrise and sunset, so no caller can
currently produce the failing combination. Fixed anyway, because the
contract is what future callers will rely on and the fix is one word.
The test file also now says why the codepoint VALUES carry no assertion:
comparing M.ICON.snow against a literal would only prove the escape was
typed twice. Whether E31A draws a snow cloud is what the glyph sheet is
for, and mutation testing confirms the assertions cannot see it.
Found by code review. The same fix is applied to the plan, so Tasks 2-5
inherit the guarded version.

DAY was 1000 against a sunrise of 1500, so every timestamp in the test
evaluated as night and the first day assertion could never pass. The
implementation was right; the test constants were not.
DAY is now 1700, inside the 1500..1900 window, with a comment saying why
the value has to be checked against the window rather than just named.
Caught by the Task 1 implementer, which stopped rather than quietly
inverting the day/night comparison to make the assertions pass.

Nine tasks, TDD throughout: the domain tables and parser get tests, the
card gets a screenshot.
The icon codepoints in the plan were each rendered and inspected rather
than derived. That caught U+E30A, which is present in the font and draws
a sun-with-rain, standing in for snow; the correct glyph is U+E31A. A
wrong-but-present codepoint fails this way, plausibly, which is why the
plan tells the implementer to look at the rendered sheet instead of
trusting a fontconfig query.
Task 6 and Task 8 both state which outcomes are acceptable when the OWM
key is still activating, so an inactive key blocks neither.
Paths are relative to the repo root rather than absolute: the first
version of this file hardcoded a home directory in eighteen places and
the pre-commit hook rejected it, correctly.
