A key built from a template, t(`timeline.zoom.${zoom}`), is invisible to
the call-site coverage guard, so a code without its message would ship as
the raw key and the gate stays green. The timeline and the day view now
word every code family (lanes, zooms, legends, readiness rows, life event
categories, precisions and errors, document kinds, notables, cycle flow,
allergy severity, screener instruments and bands, sports, functional
impact) through maps typed over the code's own union, so a new code does
not compile without its key.
Three checks hold it: one resolves every map value in all seven bundles
and pins the band and sport maps to their sources, one forbids template
keys in both trees (the one existence-checked readiness lookup is named),
and one renders the whole timeline page at every zoom and every bucket in
two languages and fails on any message key in the visible text.
The timeline and the day view showed what the server sends as it was sent:
a life event's category as FAMILY, a visit's kind as PREVENTIVE, a
document's kind as DISCHARGE_LETTER, a trip and a cycle under their
sentinel labels, a lab day as a bare "5", a mood as SUPER_GUT, a
screener as PHQ9 with its band code. A pause read as "Ramipril" at its
start and "Ramipril ended" at its end.
Every surface that shows a timeline item (lane labels, hover titles,
the screen-reader table, the selection bar, the phone chronicle) now
reads it through one wording, item-words.ts: a code goes through the
bundle's existing labels, a lab day reads "5 lab values", and a code
the bundle does not know is left out rather than shown. The day view's
title and second line do the same per event kind (mood, screener and
band, sport, severity, visit kind or planned, dose number, intensity,
functional impact, document kind), and a medication that starts, ends,
pauses or resumes says so, in the day view and in the visit
preparation alike.
A pause reads "Ramipril paused" at its start and "Ramipril resumed ·
after 11 days" at its end, on the lanes, in the selection bar and in
the chronicle.
A guard renders a record with every item kind, every category and every
kind code on each surface, in two languages, and fails on any upper-case
code or sentinel in the visible text. The wire schema now says which
fields carry codes.
A bucket that holds a mean but no lane entry is not empty; the means
say what it holds. The bar opened on such a bucket by default and called
it empty beside its own values.
Beside All, 12 months and 3 months the timeline takes a range of the
person's own choosing, from and to, through the app's date field. Each
change is clamped softly: never past today, never before the record's
first entry, never inverted, never longer than fifteen years. On a phone,
where the chronicle has no zoom control, a range button opens the same
fields with a way back to the whole record. A range with nothing in it
keeps its fields instead of the empty-record notice.
The zoom and the range live in the URL (zoom, from, to), so Back and a
bookmark return to them; a parameter that does not read falls back to
All. The API accepts zoom=range with both ends, at most fifteen years,
and picks the bucket by its length: quarters from two years, months from
120 days, weeks from 42 days and single days below, a new day bucket
whose dashed bridge spans at most three missing days. A range borrows
the grid and the keyboard steps of the fixed zoom nearest its length.
The selection bar heads a day bucket with that day.
Each value line takes the colour its type carries in the measurement
list (a --chart-N token); where two chosen lines would share one, or a
type has none, the later line in the menu's order takes the first free
data token, and a sixth line with none left falls back to the
foreground. The swatch beside the name, the line, the dashed bridge,
filled and hollow points and a ring on the selected bucket all inherit
one colour from their group. The menu, the selection bar and the phone
chronicle mark each value with the same dot. The colour map moves to an
icon-free module so the timeline does not pull the list's icons.
The selection bar is a cross-section of one bucket and now says which:
its head names the quarter, month or week in full, its entries are the
ones that touch that bucket, and each mean keeps its readings count.
Values go through the day view's formatter, so sleep reads as a
duration and the unit preference applies; the server sends canonical
units, which the old formatter took for display units. Before anyone
picks a day the bar opens on the newest bucket it has something for in
the requested window (documents, which it never lists, no longer count),
and a short line says how to pick another.
Every bucket with a reading gets its point; one with fewer than three
readings is drawn hollow. A short gap (one quarter, two months, four
weeks) is bridged with a dashed stroke between the two real points; a
longer one leaves the line open. The selection bar and the value table
for screen readers name each bucket's readings and say "no value" where
there is none. The phone chronicle names each bucket once, at its newest
month. The value menu takes up to six lines. The legend's causality line
is gone with its keys in all seven bundles.
The timeline now opens a day through the shell's day layer (openDay) and reads ?day= with its parser instead of a copy of both; the capture picker's life-event form starts on the picker's defaultDate like the other forms.
The opt-in timeline module gets its page (#613). At 768 px and up the
record's lanes (life, conditions, allergies, medications, vaccinations,
doctor and procedures, labs, documents) are drawn in one SVG on a shared
time axis, with a year, month or week grid, open periods ending in an
arrow, a dashed lead-in where a start is unknown, dose marks and pauses on
the medication they belong to, a Today line and a selection line. Up to
three neutral value lines run below as monthly means, chosen in a menu.
Recharts stays for every value chart; this surface is plain SVG like the
heatmaps.
All geometry is pure (timeline-geometry.ts): window, scale, row packing
and label placement through one occupancy map, so no label overlaps
another label or a bar, none runs past the card edge, and labels that do
not fit are left out rather than squeezed. The width comes from a
ResizeObserver, so a docked day panel re-runs the layout.
The bar under the chart names the selected month's entries as chips, the
month's means and "Open 3 Jan.", which puts ?day= in the URL for the day
layer. The chart is one tab stop: arrows move the selection by a day, a
month or a year with the zoom, Home and End jump to the ends, Enter opens
the day. A visually hidden table lists every entry for screen readers.
The legend says once that stacked means at the same time, not cause and
effect.
Below 768 px the timeline is a chronicle, newest first by month or year,
with an Ongoing block for what has no meaningful start, rails beside the
rows an episode or course spans, and empty stretches named as such.
Switching the module on in Settings opens the readiness inventory: each
lane carries, is thin or is empty, with one link per gap and the verdict
as a count. The same inventory sits as a dismissible card on the timeline
while a gap is open, and under Layers as "Data coverage".
Life events are entered in a sheet (title, kind, a date to the day, month
or year, an optional end, an optional note) from the timeline, the
capture picker and the dashboard's add menu; one surface line maps the
capture kind to the timeline module, and it is offered in one's own
record only. Deleting asks first.
Server routes are built in parallel; the e2e journey answers them with the
contract's shapes. Copy in all seven locales; the timeline and lifeEvents
release-pending prefixes are gone.
