Next 16.4 adopts a native history write a render later. A second write
inside that gap was undone when the router adopted the first, and a
write computed from useSearchParams started from the URL before the
last one. Clearing the vault's filters could therefore leave
?encounter= behind: the debounced search wrote the filters it had
rendered back over the clear.
@/lib/url-state is now the one way a page writes its own query: each
write starts from the live address bar, at most one waits for the
router at a time, and later updates queue on top of it and go together
once the router has it (or after a short grace). useUrlSearch reads the
same live value and reports each adoption. The filter hook (documents,
measurements, mood), the open document, the day layer, the timeline's
zoom and range, the medication tabs, the AI provider choice, the
Coach's ?c= and the one-shot parameter strips all go through it; the
filter changes merge into the live filters. A guard refuses raw
history writes and router writes built from the rendered params
outside the helper.
The timeline spec now waits for the values menu to hand focus back
before scrolling to the last row; it measured mid-animation and the
focus return scrolled the page back.
A step writes ?day= with replaceState, past Next's router, which adopts
the write a render later. Since 16.4 that render can land after a second
quick step and write the first step's URL back, so [ then ] pressed in a
row ended a day short. A step that finds the layer still showing another
day than the URL now waits, and publishOpenDay makes it in one write as
soon as the layer catches up. Never past today still holds for the sum.
A step read the day the layer had last published, which reaches the
shortcut and the header arrows through useSearchParams, a render and an
effect. Next 16.4 lets that chain trail a replaceState by more than a key
repeat, so two quick presses of ] both stepped from the same day and one
was lost. stepDay now reads ?day= from window.location, which the step
itself writes, and refuses a step past today on that value too.
The docked panels' strips now run from the top edge of the window to the
bottom, and the top bar ends left of them. The panel header no longer
carries a fold button in docked mode: the strip opens and closes the day
and, on /coach, the conversations; opening moves focus to the panel's
heading and closing returns it to the strip. The sheets keep a close
button, the day's now an X at the end of its header.
The command palette's door is a magnifier at every width, named Search,
with the shortcut in its tooltip. g p opens or closes the day like a
click on its strip, and below the docking width opens the sheet on the
last day or closes it; the shortcuts list shows it under Day.
The written date in the day's header is now the way to any other day. A
click (or Enter, or Space) opens a month calendar beside it: the day on
screen is selected, every day that holds anything carries a dot read from
GET /api/day/index for the month shown, nothing past today can be picked,
and a Today button sits under the grid. Picking a day swaps it in like a
step, without a new history entry; Escape closes only the calendar and
focus returns to the date. The header keeps its one line and gains no
icon; the arrows stay. The same popover serves the docked column and both
sheets, with 40 px cells for a finger.
On /coach the day now docks beside the conversation like everywhere else,
right of the conversations, instead of opening as a sheet. A neighbouring
panel can fold the docked day to its edge without moving focus
(yieldDay).
The day's count line reads "3 values, 2 entries".
A tap on a point, a bar, a calendar cell or a date now opens the day at
once, as a click does; the tooltip's second step is gone and the tapped
value heads the day. The dashboard's charts (not its today area), the
adherence chart, the rhythm events, the ECG list and detail and the rest
mode notes open their days too.
The day's header carries the close control top left, the Coach panel's
own toggle and glyph, the date on one centred line and the arrows on the
right. While the day is docked, the Coach button and the documents bar
move clear of it.
Smooth the layer: the tooltip no longer glides into place on touch, the
neighbouring day is read before a step, the sheet animates in 300 ms and
not at all under reduced motion, and the opener stays put while the page
beside the docked day reflows.
A date is now a door to its day (#613). `?day=YYYY-MM-DD` opens the day
over whichever page is open: docked beside it from 1280 px, the way the
Coach's conversations panel sits, a sheet from the right below that, and a
bottom sheet on a phone that opens at a little over half the height and
grows to full height from its handle. On /coach it is always a sheet, so
there is never more than one docked panel. Back and Escape close it, the
previous and next day replace the history entry instead of adding one,
Alt with an arrow steps a day, focus moves to the day's heading on open and
returns to whatever opened it on close, and a polite region names the day.
A malformed or future date is dropped from the URL.
The day shows the value it was opened from with its comparison, what ran
through the day, the readings against the person's own usual range on a
short number line (eight curated, the rest behind "All values"), and what
happened in order of the clock, each row linking to its record. Loading,
failure, an empty day and areas a grant does not cover each read as such.
The footer offers the timeline when that module is on and capture for the
day, with the capture forms starting on that date.
Doors into it: a click on a daily point of a metric chart (a tap shows the
value and the tooltip offers the day on touch screens), the dates in the
chart's data table, a quiet row of dots under the axis for days with
entries and a ring for notable ones, the lab chart and lab readings, the
measurement, mood and intake lists, symptom and illness day headings,
episode onset and recovery, document dates, workout dates, the workout
detail, the mood and adherence heatmaps, and the days a Coach answer's
get_day calls read, shown as chips. The next planned visit carries what
happened since the last one, each date opening its day, with a doctor
report for that window.
Not here, and frozen by a guard: the dashboard's today area, mini charts
in tiles, the cycle calendar, model-written text, future dates, the
clinician share link and the doctor-report PDF.
