Game8 and Fandom name Genshin's anniversary selectors with no word in common, and both run the same window, so the calendar showed each selector twice. Game8's own blurb names the Fandom event ("…limited 5-star selector, Tabletop Troupe: A Gathering on Adventure's Eve!"), which is how a person paired them, so merge now reads it the same way.
The rule is narrow on purpose: the whole title of two or more words, both boundaries within 24h, and never for a copy that already has a twin by title in the other source, since then the blurb is naming a neighbour such as a festival's shop. Measured on every two-source page held, it fires on the two selector pairs and otherwise only where titles already matched. Dates alone never pair: patch day puts about twenty Genshin events on one window. aliases.ts is the recorded-pair fallback for copies no page links; it is empty.

titleExtends caught a source appending words ("Bedazzling Dawnstar Sign-In") but not prepending them, which is the shape Game8's "Battle Pass - …" label took. The same qualifier at the other end now pairs too. The two-word floor holds at both ends, because a one-word base would fuse half of a patch day.

When merge fuses two sources' copies, the loser's id leaves the calendar, and it may already hold a reader's ticks from a day it was published alone. Until now that needed a hand-edited RETIRED_IDS entry per fusion.
The survivor now lists what it absorbed in an optional mergedIds field. When a feed arrives the client turns those into carry-forward pairs, skipping any id the feed still publishes, and an import takes the same table. Optional, so an older cached feed still validates and an older bundle drops it unread. RETIRED_IDS stays for parser changes, whose old ids no feed will name again.

Near matching exists to reconcile two sources describing one event under
different titles. Within one source it has no such job: the page has already
told us these are two rows, the parser has already dropped repeats of the same
id, and fusing them overrules a distinction the publisher made on purpose.
The loose 0.80 threshold that makes the rule useful across sources makes it
actively wrong within one. Umamusume's banner list runs "3 Star Guaranteed 1.5
Anniversary Scout (Character)" and "(Support)" concurrently — titles differing
by a single parenthetical, starting the same day — and fusing them dropped a
live banner off the calendar with nothing anywhere reporting it. A silent drop
is the failure this codebase ranks as the dangerous one.
Same-id fusion is untouched, so nothing duplicates.

First non-Game8 parser, and the first source that states region-scoped ends:
wiki.gg emits ISO timestamps with one timer per server region, so Endfield
events now carry exact times and separate Asia / Americas-Europe ends. That
gap is up to 13 hours, which is what regionEnds was built for.
Two sources for one game also exercised merge for real. It caught both
overlaps — including "Bedazzling Dawnstar" against Game8's "Bedazzling
Dawnstar Sign-In" — and flagged that the two disagree on the end date by 70
hours rather than averaging them into a date neither states.
Matching an appended qualifier needed a prefix test, not a subset test: a
subset would also fuse "Gold Clash" with "Gold Rush Clash Royale".
Also fixes build-feed picking fixtures by game rather than by source, which
handed the wiki.gg page to the Game8 parser once Endfield had two.

Collapses the same event seen by two sources, matching on ID or on title
similarity plus start-date proximity. Proximity is the real guard against
false positives, since a rerun reuses its name months later.
Agreement from an independent source raises confidence; the same row seen
twice in one document does not. Disagreement on an end date is recorded as
a conflict for the review gate rather than averaged — splitting the
difference would publish a date neither source asserts.
