A logbook is three items at once, and the search asks about one of them

[JIRPOS]

Release notes

ADDED: Expedition Logbooks are priced. Copy one and the panel reads it as what it is — an
expedition that can go to up to three different places, one of which you will pick.

Each destination is a line of its own: the faction whose land it is, in bold, and the area it
leads to underneath. Pick one and the search is about that destination; the others stay on screen
with where they lead, one click away. That is the whole point of it — a logbook with a valuable
faction on it is worth what that faction is worth, and asking the trade site for all three
destinations at once finds the single copy in the league that happens to lead to that exact trio.

The chosen destination brings its area and the modifiers that apply there as rows you can switch
on; neither is on by default, because a buyer choosing a faction is rarely choosing the area with
it. The area level is searched, as a floor — an 83 answers a search for an 80. The item level, and
the quantity, rarity and pack size a magic or rare book grants, are offered but left off: unlike
a map, a logbook is not run for those. The affixes it prints below its destinations sit under the
section at the foot of the list, the way a map's do — a currency re-rolls them, so they are not
what the book is bought for, but they are still one tick away when they are the question.

Review notes

ADDED: Expedition Logbooks are parsed, priced and searched — Strategy::Logbook, an item
class the app had no reading for at all.

ADDED: A destination is structure rather than modifiers — its area, its faction and its
implicits are one LogbookArea, recognised by shape rather than by a table of factions.

• The two leading lines are matched on being bare names and the tail on reading as modifiers, so
  the four factions and the dozens of areas stay game data. The number of implicits is not fixed:
  the captures show two and three.

ADDED: SearchPlan::choices — a set of filters the search sends one of, drawn as a radio
at the head of the filter list.

• A logbook lists up to three destinations and the player travels to exactly one, so a query
  naming all three prices the single copy in the league that leads to that trio, and one naming
  none prices every logbook in the league. The alternative's own row is its faction filter
  rather than a heading over one — drawing it again underneath offered to untick what the radio
  button had just decided.

ADDED: The faction and the area join to their pseudo.* stats through two lexicon terms, the
shape SanctumEffectPrefix already had, so no faction name is compiled in.

ADDED: The area level is searched as a floor and ticked; the item level, quantity, rarity and
pack size are offered unticked.

• Measured on the rare capture: category, type, map_filters.area_level at 80 and the faction
  pseudo together return 983 listings, so all four are indexed for this category.
• Quantity, rarity and pack size are unticked because a logbook is not bought for them, not
  pending a measurement. It is the one place this parts company with the map keys it borrows: a
  map is run for its quantity and pack size and ticks them, and a logbook's are a second-order
  bonus on top of the artifacts the destination decides. They also only exist on a magic or rare
  book, so ticking them would search the same logbook two ways depending on whether it had rolled
  affixes at all. Nobody has measured that the site indexes them for this category either.

ADDED: "Dannig" is a usage needle, or a logbook's usage note comes back as a modifier.

ADDED: Three captures — a normal, a rare and a magic logbook — and the bundle slice they need.

CHANGED: A destination's implicit is seeded as a floor with no ceiling.

• Trade indexes an item's implicits as one total per stat and every destination feeds it: the rare
  capture's 14% and 16% Explosives are indexed as 30%, so a ceiling from one destination asks the
  other two not to exist.

CHANGED: merge_same_stat never folds across a choice, as it never folds across hidden.

CHANGED: The strategy picker offers neither reading for a logbook, as it already does for a
heist item.

Not in this change

Two of the five affixes on the rare capture resolve to nothing, and it is a data-side gap rather
than this strategy: +#% Monster Chaos Resistance and +#% Monster Elemental Resistances are
published with the sign inside the matcher, and placeholder_form replaces the sign along with
the digits, so nothing the clipboard prints can reach them. 34 of the bundle's 15,148 matchers are
shaped that way and it affects maps as much as logbooks. The pricing case asserts three hidden
affixes for that reason and becomes five the day it is fixed.

Split is not parsed, not filtered and not mentioned — asked for, rather than overlooked.
