The board's live title+body filter per 04-interactions.md § Search:
- SearchFilter — a pure value folding the query once (case- and
diacritic-insensitive substring, locale-stable); title OR body matches,
attachment filenames never searched; only the literal empty string is
inactive.
- One universe: the filter threads through SelectionGrammar's order lists
as a defaulted parameter, so ranges, Select All, arrow navigation, the
marquee, drop zones, count badges, and the shown trash all read the same
filtered set by construction; lanes are deliberately never filtered out
(an emptied lane keeps its slot with a 0 badge). Hidden cards leave the
selection through the existing constrain primitive, run on every query
change and as the last line of the reload resolve; the delete successor
is filtered so ⌫ never selects a hidden neighbour.
- The field: an NSSearchField-backed toolbar item (the toolbar's sole
default item); Edit ▸ Find ⌘F focuses it through a focused-value
presentation; stock field-editor dispatch — Return swallowed, Tab is the
keep-filter path to the board, board commands stay enabled except the
caret-chord pair, now one shared caretChordsYield expression.
- Escape is staged: clear the non-empty query (focus stays), hand an empty
field back to the board, clear an active search from board focus —
before Escape's clear-selection meaning.
- Creating a card clears the search (the placeholder funnel); a rename
deliberately gets no carve-out; filter reflow rides the content spring
keyed narrowly on the query.

One named home for every curve and duration — the two-voice split 03
fixes (snappy structural: drag reflow 0.18, delete 0.25, lane resize
0.2; smooth content-reflow 0.28), the scale-and-fade appear/disappear
transitions (cards 0.8, lanes 0.9), and a Reduce Motion variant on
every accessor (animations go instant, transitions go crossfade). A
post-migration grep holds the invariant: zero motion literals outside
Motion.swift. The animate-vs-snap split lands where Lanework's
one-way flow puts it: the store's reload seam. An app-mediated echo
applies its snapshot inside the structural transaction; foreign and
reconciling reloads — and every bracket-ending wholesale reload —
assign bare, because live-reload is the board becoming what's on
disk, not an event to perform. A window that merged foreign events
into an app-mediated span animates, deliberately: the ratified merge
rule makes it indistinguishable from a pure echo, and a test pins
that reading so a future mixed case fails loudly. The lane-reorder
reflow keys on the drop proposal alone (pointer tracking stays 1:1),
the resize session freezes its Reduce Motion answer at drag start so
the unit tick and the window resize can never disagree, and the m5
drag / m5 search / m7 undo voices are named seams waiting for their
call sites. 13 new tests.
