The Driver asked for the SAME caret the cards already have on the Prayer
List, with two entries -- Full detail and Lightweight -- and said plainly
not to destroy the print options that exist. So nothing is merged, nothing
is removed, and the Poster is untouched.
There was no dropdown COMPONENT to reuse: the cards' caret is an inline
disclosure, one ref plus a sibling tape of plain buttons, deliberately not
a <select> because a native dropdown collides with other dropdowns on the
host page. So the PATTERN is generalized rather than copied. deckOpenFor
now holds a compound `${id}:${which}` key, which keeps "opening one closes
the others" free -- copy/paste would have given two open-states, and two
tapes could then sit open at once and overlap in the grid gap.
While wiring it, a real defect surfaced: THE WALL'S PRAYER LIST BUTTON HAS
NEVER PRINTED A PACKET. downloadPacket calls printList, a columnar table of
name/country/population/religion. The packet -- map, life calendar,
%-evangelical grid, triangle, profiles, wheel, points -- is printPacket,
which every other surface calls and this wall never did. That is a direct
cause of the packet "not following the design that was asked for" here: no
change to the renderer could reach a button that was not calling it.
printList stays exported for any surface that still wants the list.
The two packets are a FILTER over the existing page array, not a second
code path, so they cannot drift apart in layout, i18n, RTL or print scale.
The filter is keyed and never indexed -- an index filter reads identically
today and drops the wrong page the first time the order changes, and that
order is the Driver's. listPages is deliberately outside the filter: a
variant may drop a FIXED page, never one whose count depends on the data,
because that drops people silently. An unknown variant falls back to full.
internal/check-packet-variants.mjs pins all of it, and was mutation-tested
rather than trusted: dropping list pages, reverting to printList, adding a
second open-state ref, and typoing a variant id each fail with their own
message.
