Marc-André Bombeck fdd34f2c5e fix(charts): keep a chart's window open to the end of today
A chart showing the last N days fixed its window end at the mount
instant. The query key kept that bound, so the refetch after a new
reading asked for the same old window and the reading stayed hidden
until the range tab was switched. The window now ends at the end of
the current day in the profile time zone (openEndedFetchWindow, keyed
on the day): every reading saved today falls inside it, the cache key
stays the same all day, and it moves on after midnight. The dashboard
batch shares the end-of-day helper.

Marc-André Bombeck 313d8491de feat(measurements): read a sleep duration written as 7:30 or 7h 30m
The sleep field asked for decimal hours only. A shared parser
(parse-duration.ts) now reads a bare number with point or comma,
H:MM, and hours and minutes with unit words (7h, 7h30, 7 h 30 min,
45m), answers in the field's unit, and refuses a negative, unknown or
longer-than-a-day entry. The form shows how the entry was read under
the field and puts a refusal on the field itself. The stored value and
the API are unchanged.

Marc-André Bombeck dd7636e147 feat(labs): refuse a biomarker unit change while readings are linked
Readers label every linked reading with the marker's unit, so changing
it relabelled stored numbers without converting them. PUT
/api/biomarkers/{id} now answers 422 biomarkers.unit.locked with
meta.readingCount when the unit differs and any reading (tombstoned
ones included) is linked. The marker editor says so under the unit
field.

Marc-André Bombeck 7022b698e7 fix(ai): forget the remembered working provider when the chain is saved
The in-memory memo of the last provider that answered reorders the
chain for up to an hour. Saving a new chain now drops it for that
account, so a provider the person removed or disabled no longer leads
the chain they just arranged.

Marc-André Bombeck 916f918674 feat(workouts): save an edited resubmit of a hand-entered workout
The manual form sends one manual: id per opening and resends it after
an edit. The batch route now treats a MANUAL entry with a manual: id
as an overwrite, the way stats: measurements are: the stored row takes
the new values and the entry reports "updated", or "duplicate" when
nothing changed. Records keyed on the workout are removed under the
personal-records lock and re-derived. Every other id stays
first-write-wins. The status enum gains "updated".

Marc-André Bombeck 6bb65824bf fix(workouts): serialise record detection with a workout delete
The workout-slot detection reads the best workout and writes its record
inside one transaction under a per-user advisory lock, and the workout
DELETE takes the same lock before removing records and the workout. A
delete can no longer land between the read and the write and leave a
record for a workout that is gone.

The DELETE's match for a legacy record without an external id is scoped
to the slots of the deleted workout's sport, so a record another sport
set at the same instant stays.

Marc-André Bombeck ab081d2a85 fix(workouts): keep a deleted workout's insight slot spent
The insight claim row is now the daily-cap ledger. Its workout_id is
nullable with ON DELETE SET NULL (migration 0367), so deleting a workout
no longer frees the day's slot. The cap counts claims that reached the
provider plus live leases, and drops the separate count of insight rows.
A daily workout-insight-claim-cleanup queue removes claim rows untouched
for seven days.

Marc-André Bombeck a14ae57283 fix(workouts): refuse a manual workout that would end in the future
The form's start defaults to the minute it opened, so a workout logged
right after it finished was stored as ending up to a day ahead. The
duration now fails validation when start + duration lies past now, with
the same one-minute slack the start check uses.

Marc-André Bombeck 5ee1b3e28f fix(ai): run every model call under the response-timeout setting
The response-timeout setting reached the briefing, the status notes and
the Coach, which threaded it by hand. Document reads, document
extraction, lab OCR and lab staging called the provider without a
timeout, so every client fell back to its own 60 s literal and a slow
self-hosted model was cut off however high the setting stood.

The setting now rides on the provider instance. resolveProvider,
resolveProviderChain and resolveProviderForTest stamp the record's
aiResponseTimeoutSeconds on everything they return, and each wire
client reads its ceiling through callTimeoutMs: the setting, else the
surface's own timeoutMs, else 60 s. A call site no longer has to pass
it, so a new one cannot forget it. The connection test runs under the
same ceiling a read does.

The Coach nudge tick and the reaction line keep their short ceilings
(timeoutPolicy: "surface-ceiling"): the tick runs accounts one after
another under a shared budget, the reaction line's claim lease is
shorter than the largest setting, and both have deterministic copy
that stands in.

/api/auth/me publishes the effective value as
ai.provider.responseTimeoutMs, so a client can size its own request
timeout from it instead of guessing.

Marc-André Bombeck cf678f6ec4 fix(dashboard): gate every add-menu entry on its module, as the capture picker does
The dashboard add menu asked only whether the record's section was

Marc-André Bombeck e0fc879d72 feat(workouts): log a workout by hand from the workouts page
A small sheet with sport, start, duration and optionally distance and
active energy, nothing else. The start is read in the profile timezone,
distance in the reader's unit and stored in metres. It saves through
POST /api/workouts/batch as source MANUAL with an external id minted once

The workouts page carries the action in its header and in the empty

Marc-André Bombeck 885efaafd9 fix(dashboard): open the body fat page from the body fat tile
The body fat tile was the one strip tile that led nowhere. Its href map
said there was no dedicated sub-page, which was true: body fat percentage
was tiled and charted on the dashboard but never got the Insights page
every body-composition sibling has.

Add /insights/body-fat on the generic metric-page scaffold (body group,
tab-strip pill, seven locales, manual-entry empty state) and link the
tile to it.

Move the tile href map out of the page into tile-destinations.ts, keyed by
the tile-capable widget id and typed against the sub-page slug union, so
a missing or non-existent destination fails to compile. The link passes
the destination's insights-page surface gate, so it never points at a
page a switched-off module hides.

A guard derives the tile set from TILE_CAPABLE_WIDGET_IDS and from the
ids the dashboard actually pushes into its strip, and fails when a tile's
metric has a sub-page the tile does not open, when a destination has no
route, or when a tile links to a page owned by another module. Tiles that
deliberately lead nowhere need a written reason; there are none today.

The reverse-lookup test pinned BODY_FAT as having no page; it now
resolves to body-fat.

Marc-André Bombeck debd44a75b fix(charts): keep axis unit labels on one line; 44 px date and time triggers
Recharts word-wraps a tick label that it measures wider than its axis,
and it measures in the page's body font rather than the tick's 11 px.
"62 bpm" on the pulse chart under a workout and "106 mg/dL" on the
glucose page therefore broke onto two lines at every width, and the
pulse chart's second line sat on the first x tick. Axis units are now
joined with a no-break space through `axisUnitSuffix`, so the label is
one word and stays on one line. A guard fails when a chart axis joins a
unit with a plain space.

The calendar and clock buttons in the date and time fields paint at
32 px; a `::before` halo now gives them a 44 px touch target without
changing the field.

Marc-André Bombeck 801295f55a fix(dates): read date-only lab and document dates as calendar dates
A date-only value is stored at 12:00 UTC. The lab list and history, the
document cards and pickers, the document date suggestion, extracted
fact dates, source-picker rows and the compliance and mood heatmaps
formatted that instant in the reader's zone, which is the next day from
UTC+12 to UTC+14.

`useCalendarDate` formats such a value through the UTC-pinned calendar
formatter the vaccination list already uses, with the same field order
and locale as instant dates. Lab readings hold both kinds, so
`useLabDate` reads a noon-UTC anchor as its calendar date and a reading
typed with its time of day in the reader's zone. A document without a
filing date shows its upload day, an instant, in the reader's zone.

Marc-André Bombeck fe13fa966b fix(labs): print range bars and lab values in the reader's number format
Range bars and the lab list, detail rows, chart tooltip and reference
ranges printed numbers with a plain `String()`, so a German reader saw
"1.8 mIU/L" and "61.3 kg" under a German interface. The same was true
of the mean, GMI, eA1C and the advanced indices on the glucose panel.

`RangeBar` now prints value, bounds and delta through the locale number
formatter and takes an optional `formatValue` for surfaces with their
own precision. Lab values keep their trim rule (whole numbers bare, at
most two decimals) in `formatLabValue`, which now hands the digits to a
caller-supplied locale formatter; `useLabNumber` wires it to the
reader's locale for every lab surface. Inputs are unchanged.

Marc-André Bombeck 75361d0666 fix(glucose): state band edges in the reader's glucose unit
The time-in-range labels in the doctor report, the target caption on
the glucose panel, the glucose page description and the fasting
explainer printed fixed mg/dL figures, so a reader on mmol/L saw
"Low (< 70 mg/dL)" beside values in mmol/L.

The cut-points now live in one place (`GLUCOSE_TIR_CUT_POINTS`,
`GLUCOSE_FASTING_CUT_POINTS`) with the SI figure each guideline prints,
the analytics engine counts its bands from the same constants, and
every sentence takes the band edges and unit as parameters through
`glucoseBandParams`, formatted with the reader's number format.

The unit-preference guard now also reads the locale bundles: a string
that names mg/dL or mmol/L fails unless it is allowlisted with a
reason.

Marc-André Bombeck 08d5acdcb5 feat(measurements): log a resting heart rate by hand

chart and series, so a value read off a watch or taken on waking could only
land among spot pulses. The form now offers it next to pulse. The server

the form, the dashboard summary, the resting-pulse page, its trend slot and
its correlation channel now follow that module too.

Marc-André Bombeck 615f5a8070 test(units): sweep the AI and Coach producers for unit literals
The unit sweep covered the display trees and the insight library; the
prompt and snapshot builders, the text-writing jobs and the target and
digest producers were outside it, which is where a band in mg/dL, a
threshold in kg/week and a distance in metres reached the model. The
sweep now walks those trees too and matches prose units ("kg/week",
"5 metres") as well as symbols. The four allowlist entries for prompts
that stated weight in kilograms are gone with the literals; the new
entries each name why the literal is not a reader-facing unit.

A line scanner cannot see a canonical number printed with no unit at
all, so the guard also names every producer that carries a
preference-dependent figure into a prompt, a snapshot or a stored
sentence and requires each to call a reader-unit resolver. The canonical
weight signal of the day loses its kilogram label; the reader's unit is
attached where the signal is converted.

Marc-André Bombeck 43be8ebd43 fix(jobs): hand the reaction line its new datum in the reader's units
The reaction line read the arrived weight with its stored unit (kg) and
a workout distance in metres, whatever the reader had chosen, so the
sentence written about the new reading could quote kilograms to a
reader on pounds. The evidence now converts the reading and the
distance into the reader's units before the prompt is built.

Marc-André Bombeck 7cb1b5ba05 fix(insights): write the weight note and its thresholds in the reader's mass unit
The weight status note had its own generator and never took the unit
preference: its signal, summary, graded series, latest-day figure,
target band and correlation pairs were all in kilograms, and the card
prompt stated the normal day-to-day swing, the plateau line and the
loss pace in kilograms too. A reader on pounds was handed both units.

The generator now converts every weight figure once after the canonical
arithmetic (the correlations are scale-free and stay as computed), the
card prompt states its thresholds in the reader's unit, and the unit
preference joins the input fingerprint so a switch is never answered
with the old note. The shared status-card examples and the briefing's
plateau pattern no longer show a weight in kilograms for the model to
copy.

Marc-André Bombeck d11c165675 fix(coach): read the cycle contrast and the metric table in the reader's units
The cycle block's headline contrast labelled weight in kg and the
temperatures in °C, and left a glucose contrast without any unit. The
metric table, which the person sees and whose summary the model reads,
listed weight in kilograms, temperatures in degrees Celsius, walking
speed in metres per second and distance in metres.

The cycle contrast now converts both means and the gap into the
reader's units (the gap by the factor alone) and names the unit in its
sentence. The table resolves each column's unit and decimals from the
reader's preferences and converts every folded period value once; the
snapshot carries the preferences it was written in, so the table and
the snapshot of a turn always agree.

Marc-André Bombeck ca5ce518d8 fix(coach): state the snapshot's weight, body and distance figures in the reader's units
The Coach snapshot carried weight, body composition, temperatures and
walking speed and distance as stored: kilograms, degrees Celsius, metres
per second and metres, with no unit on the block. The evidence-block
rules then listed kg and both glucose units as the units to cite. A
reader on pounds, Fahrenheit or miles was answered in the units they do
not use.

Every value block now converts its timeline (and the weight block its
aggregate and coarse tail) into the reader's units after aggregating on
the canonical value, and names the unit on the block; the grounding
scalars stay canonical. Workout distances arrive in kilometres or miles
with the unit named once. The prompt in every locale tells the model
that a block's figures are already in the reader's unit and takes the
evidence-block unit from the block instead of a fixed list.

Marc-André Bombeck a7e6b89672 fix(insights): hand the briefing its figures in the reader's units
The daily briefing serialised the aggregated feature set as computed:
weight, grip strength and the weight target in kilograms, waist in
centimetres, glucose and the signals of the day in mg/dL (the glucose
signal carried no unit at all), workout distances in kilometres. A
reader on pounds or mmol/L got a briefing in units they do not use.

One step now converts the feature set after all canonical arithmetic,
on both the nightly and the on-demand path: absolute values through the
full transform, differences and slopes through the factor alone, every
converted block labelled, workout distances under unit-neutral keys.
The prompt, the stored fingerprint and the grounding check all read the
converted set, so a unit switch moves the fingerprint and the grounding
check compares the reply against the figures the model was shown. The
weight target sentence, the comparison block and the GLP-1 plateau
context quote weight in the reader's unit; the comparison block also
labelled sleep as hours while carrying minutes.

A unit switch now also re-warms a cached briefing alongside the status
notes and narratives.

Marc-André Bombeck d1b2539b1f fix(coach): state reference and time-in-range bands in the reader's units
The reference grounding printed the fasting glucose bands in mg/dL and
the body-temperature band in °C, and the system prompt described time
in range as 70-180 mg/dL. For a reader on mmol/L or Fahrenheit the
model was handed one quantity in two units: the glucose block in
mmol/L, the band beside it in mg/dL.

The grounding block now takes both unit preferences and prints the
general, the diabetes goal and the temperature band in them, while the
placement is still classified on the canonical value. The glucose
block carries the time-in-range band in its own unit, and the prompt
points the model at it instead of naming a unit.

bounds, the avatar against the upload's sniff and limits. A refused value is

  metadata in the disaster-recovery arm.
- NutrientIntakeDay.externalSourceVersion and createdAt: neither was

Marc-André Bombeck b4577f5c31 test: give every scanning guard a floor on what it found
A guard that compares a sweep against an allowlist, or against "none of

does with the walk.

- requireFloor(label, found, floor) throws below the floor and refuses a
  floor of zero.
- scanSourceMatches(root, pattern, { fileFloor, matchFloor }) walks, matches
  and floors both the files read and the hits found.

Floors added, pinned at the current counts:

- coach_usage owner columns: the clauses it actually examined (6).
- measurement reference index: the foreign keys it extracted (2).
- job outcome fact inventory: job files (130, floor 120) and fact keys
  (399, floor 350).

- locale integrity: message bundles (7).

Marc-André Bombeck 5caa15f4e1 fix(google-health): count sleep segments with a stage label the mapper does not know
A segment whose stage label was unknown (SLEEP_STAGE_TYPE_UNSPECIFIED, or a
label added upstream later) was skipped without a trace, so the night total
read short and nothing said why. The mapper now counts those segments and
keeps their labels, and the sleep sync puts both on its wide event.

Marc-André Bombeck 8821fdeb54 test(tz): run core day paths with the host at both edges of the clock
The suite and the production image both sit near UTC, so a UTC day and a
local day agree for most of every day and day-boundary defects kept
passing. The harness sets the host zone in code to Los Angeles and to
Kiritimati, gives the account the same zone, and checks a schedule slot,
a course's last day, a mood entry, the dashboard summary's mood instant
and a document date round trip at the instant where the local and the
UTC day differ. Unit tests cover the new date-only and key helpers.
