Three parsers decide currency against ctx.now, because their page has no
"ongoing" heading worth trusting: bawiki.ts, and the Fate/Grand Order and
Infinity Nikki branches of fandom.ts. All three compared Date.parse(endsAt) to
now, and all three publish day-precision ends — so the comparison was against
the 00:00Z placeholder, which § Domain rules says is not an instant and nothing
may read literally.
clockFor already knows that and resolves such a boundary to the reset opening
that game-day on the reader's server. The parsers did not, so the feed retired
a row up to nine hours before the app, the countdown and the game all agreed it
was over. On the pinned Infinity Nikki fixture, "Inspiration Burst" left the
feed at 2026-08-22T01:00Z while clockFor still called it live for an American
reader until 09:00Z, and the page said it ran to 03:59 server time. The reader
does not see a stale row; they see the deadline they were counting down to
disappear on its last day, which is the silent drop this codebase treats as the
dangerous failure.
latestBoundaryMs answers clockFor's question for the last region rather than
one reader's, so a row is history only once it is history everywhere. It follows
a game's own server map and reset hour for the same reason clockFor does —
Endfield and Reverse: 1999 both move. Nothing stored changes: this is one
comparison, not a resolved boundary written into the feed, and no expected.json
moves.
Being generous by nine hours costs an expired row at the bottom of a list.
Being strict costs a live one.

A source that prints "August 19, 2026" and no time is stored at 00:00Z,
which is a placeholder for "somewhere in this day" rather than a claim
about when the day opens. The countdown read it literally, which turns it
into exactly that claim — and the UTC day is nobody's. Wuthering Waves
events dated the 19th were still running three hours after we had retired
them, because a European player's day opens at 04:00 on a UTC+1 server;
Asia was four hours out the other way and America nine. Sixty-two of the
eighty-six published events were affected, across ten of thirteen games,
so the reader was reading a wrong number far more often than a right one.
A day-precision boundary now resolves to the reset that opens that
game-day on the reader's server — the same grid daily.ts keys every tick
by, and the only clock we hold for a game. That is a reading of the date
the source printed, not a time invented for it: nothing stored moves, no
event ID moves, and the parsers still refuse to guess.
Two boundaries are never re-anchored. A regionEnds value is already the
instant a source stated per server, so anchoring it would throw a fact
away. And an event the reader typed in was resolved by readerInstant in
their own timezone, which is a stated time too — theirs.

Time is this product's subject, so the vocabulary lives in one module:
remaining, progress through a window, and urgency. Urgency is derived from
absolute time left, deliberately independent of proportion — a 90-day event
with three hours left is as urgent as a 3-day one.
An unannounced end is never urgent and has no progress: "we don't know" and
"loads of time" are different facts, and conflating them is what this
product exists to avoid.
Games carry a hue for identity only. Urgency is a separate axis, so one
glance answers both "whose event is this?" and "how long have I got?".
