The top of an answer is one line that says what the Coach is doing right
now (thinking, fetching a metric, summarising the readings, writing),
live from the activity frames, with the seconds so far. It never opens
by itself: the trail stays closed while the turn runs, when it asks,
when it stops early, after the answer and after a reload, and opens
only on a tap. Once the answer is in, the line settles into one summary
of lookups and seconds. A table read during the turn shows as a
one-line preview with a sparkline until the answer takes it over.
Clarifying choices, follow-ups and the answers to a fact or plan
proposal share one pattern: quiet pills in the answer's column whose
tap sends the label as the person's own message. The clarification
card and the in-thread plan card are gone. A fact the Coach kept is one
meta line with Undo, an assumption one line with Change. The remember
button on a message now keeps it in the Coach's memory.
The compare chart replaces the placeholder that rendered nothing: two
periods overlaid on one axis (the earlier one dashed), or two metrics on
two axes whose grid lines meet. Same tokens, legend and tooltip as the
other result charts, which stay as they were. The legend key is spelled
out so the chart runtime does not pull the Coach's schemas into every
chart.
Add the shared contract the reasoning release builds on, with no change
to how a turn runs today.
- Schema: operator reasoning controls on app_settings (0376), the
encrypted trail text on coach_messages (0377), and source,
last_used_at and source_message_id on coach_facts (0378).
- Provider contract: CompletionParams.reasoning and onReasoning,
CompletionResult.reasoning and providerState, AiMessage.providerState.
- Reasoning levels, thinking budgets and the background-job table in
src/lib/ai/reasoning/levels.ts; coachPrefsJson.reasoning, absent
meaning medium, salvaged field by field like every other pref.
- Stream: activity, memoryNote and planProposal frames, done.stop and
done.withheldResults, result.interim, a compare chart kind, eight
table refs, three more clarification kinds with an assumed choice,
the change_assumption chip, and assumptions, activity, stop,
memoryNote and planProposal on the provenance. Zod mirror, type
parity and the native-client key rule cover every new frame.
- Chat request: memoryDecision and planDecision, parsed and not yet
acted on.
- Stub contracts for the memory functions and the activity recorder,
inert until their implementations land.
- Backup, restore and rotation carry the new columns; a fact's message
reference is resolved against the restored messages like its
conversation reference.
- Message keys for the trail, memory, plans, assumptions, replies,
interim tables, comparison charts and reasoning settings in all seven
locales, each reachable from a catalog and checked both ways.
The panel groups conversations by the browser's local day, so the e2e
fixture's "an hour ago" landed in yesterday when CI ran just after
midnight. The turn-steps test reads its markup by splitting rather than
with a replace CodeQL reads as an incomplete sanitiser.
Below md the score ring sat centred under the Today facts as a 168 px
dial, where the bottom navigation covered it. The hero is now one
grid with two arrangements: on a phone the ring is a compact 80 px
dial at the top right beside the lead and signal line, flush with the
card's trailing edge, and the Today facts run the full card width
under both; from md up the ring spans both rows of the trailing
column exactly as before (desktop captures are pixel-identical).
Without a lead the facts take the leading cell, so the ring never
sits beside an empty row.
ScoreRing gains a `responsive` size (80 px, md:168 px) whose label is
left out below md; the ring keeps its aria-label and the surrounding
link names it. The meta lines under the phone dial are capped to its
width, so the lead keeps at least 180 px beside it at 360 px.
Each fact now stacks its muted label above its foreground value on
the reading edge at every width, instead of a label-left /
value-right row that broke long values into a ragged right-aligned
block. Rows stay at the 44 px tap floor below md.
The Today overview e2e covers 1440, 390 and 360 px in both themes
for an AI lead, a long AI lead, an AI-off day and a quiet day, and
asserts the dial size, its place beside the lead, symmetric insets,
full-width facts and stacked 44 px rows on a phone.
Inside a chat turn every tool read lands on the turn's shared full-source
snapshot when its window matches. On an account with many synced series
that build passes the prompt budget, and the budget pass collapses blocks
to a bare unit and then to an `{ omitted }` marker. get_metric_series
sliced the marker out and answered `present: true` with it, so the model
was told the readings exist and was given no figure. The same held for
sleep, glucose, compliance and workouts.
- The snapshot result names the blocks the budget pass cut. A tool whose
block was cut in the shared build reads it again from its own source at
the same window.
- A read scoped to one source condenses its own blocks last and never
swaps them for the marker: it keeps a summary (first, last, min, max,
mean, change) taken before anything is cut, the newest daily values,
weekly means folded into monthly means, and names each cut.
- get_metric_series never answers present with a block holding no figure;
that read reports retrieval_failed instead.
- A chat series read carries the readings it counted, so the step shows
them, and on a long or condensed window a note on what it covers. The
tool description and a new tool-mode rule tell the model to call
get_metric_table itself for longer history instead of asking.
- The screen-reader comma between step parts is unselectable, so a copied
row no longer reads "Weight · ,all time".
MCP output is unchanged: the source-snapshot equality suite stays green.
Every text-entry control (Input, Textarea, Select and NativeSelect
triggers, the date and time fields, the calendar's dropdowns, the Coach
composer and the hand-built note fields) now marks focus by turning its
border the new neutral input-focus tone, about 5:1 on the dark
background and 4:1 on the light one, with no ring. A text field matches
:focus-visible on every mouse click, so the ring was on for everyone.
An invalid field keeps its red border and draws its destructive ring
only while focused. Buttons, links, checkboxes and switches keep their
rings.
text-field-focus-guard.test.ts fails when a text-field class string
brings a focus ring or a primary/ring-coloured focus border back.
A standalone PWA on a tablet reserves the status bar in the top bar but
not in the docked panel's header row, which could tuck its title and
icons under the status bar; the new-chat button sat without the home
indicator inset. Both now reserve the same insets as the top bar.
The docked panel was part of the page, below the top bar. It is now a
column of the shell beside the content column, portalled through a new
side-panel slot: it runs from the top of the window to the bottom, flush
right, and the top bar ends at its left edge. Shut, the panel is gone
entirely and the top bar runs to the window's edge. The panel's header row
is the top bar's band, so the two bottom borders draw one line; the panel
takes the sidebar surface and border, like the rail on the left.
The top bar says where the reader is on desktop: "Coach", then the open
conversation's title, truncated. The panel toggle is its last item, 12 px
from its trailing edge, so it stands against the open panel and at the
window's edge when the panel is shut; it carries a tooltip and is 28 px
beside a fine pointer, 44 px with touch.
New chat is a round 48 px primary button with a plus, 24 px in from the
panel's corner (16 px in the phone sheet), with a tooltip. The top bar's
action slot and the new context and side-panel slots share one portal
helper.
Focus opens the details tooltip, and the click that Enter or Space then
fires toggled it shut again. A click with no pointer-down before it is a
keyboard activation and now always opens; a tap or a mouse click still
toggles, and Escape closes it.
The panel header buttons shrank to 28 px from md and the conversation rows
to 36 px from sm, so a touch tablet wide enough to dock the panel got
pointer-sized targets. They now shrink only under pointer-fine: 28 px
header buttons, a 36 px gear in the drawer, 36 px rows and row menus
beside a mouse or trackpad, the 44 px floor with touch at any width.
A unit test refuses a width breakpoint on a control size in the three
panel files; an e2e case measures the docked panel at 1280 px with touch
and with a fine pointer.
The tokens and model no longer sit as right-aligned text under a Coach
answer. The row is one left-aligned group: copy, read aloud, try again, a
details icon, then the time. The details icon is a focusable button whose
tooltip names the model and the token count; it opens on hover, on
keyboard focus and on a tap, and a second tap, a tap elsewhere or Escape
closes it. Strings in all seven locales; the joined tokens-with-model
string is gone.
The toggle shows the panel-right open glyph while the panel is open and
the close glyph while it is shut, both mirrored so the chevron points the
way the panel moves on a click. Docked and open, the toggle keeps the
panel's width as its right margin, so it sits beside the panel's leading
edge and travels with it (200 ms, none under reduced motion). Labels and
aria-expanded are unchanged.
The Coach page cancelled the shell's container padding with negative
margins, so <main> kept its reserved scrollbar gutter and painted a dead
strip to the right of the panel on classic-scrollbar platforms. The shell
now renders /coach full bleed: no centred container, no padding and no
reserved gutter, and the page fills what <main> leaves below the top bar.
A refusal card (shared record, module off) keeps the padded frame.
The panel header takes one 12 px inset with a gap of 8 between title and
icons, a text-lg title, and 28 px icon buttons beside a pointer (44 px on
touch). Conversation rows take the control radius and a 36 px pointer
floor.
The same-hours comparison cut the earlier days at the current clock time.
At two in the afternoon a day holding only its fasting reading was then
held against mornings plus lunch, and read as below its range again. The
earlier days are now cut at the local time of today's latest reading.
A range read this way is the usual range for this time of day, not the
whole-day band other surfaces show. The deviation carries a basis, the
health-status API publishes it as `basis` (`day` or `sameHours`), and the
Today lead and the health-status card name the range as the one for this
time of day, in all seven locales.
/coach?settings=data opened the conversations sheet from the first
render. The server and hydration renders do not know the viewport and
take the narrow layout, so on a desktop the sheet was open until the
docked panel replaced it; only the batching of the hydration re-render
kept it off the screen. The deep link now opens the sheet only once
hydrated on a viewport that does not dock the panel; on a docked one the
panel is revealed as before.
The desktop deep-link spec records every mount of the sheet from the
first byte and expects none; a phone deep-link spec covers the sheet
path and serves as the watcher's positive control.
Jumping to the latest message pinned the thread first, which hides the
button behind aria-hidden, and only then moved focus to the composer.
Focus now leaves the button before its state changes.
The provider and model selects in the Coach's settings already lock while
a write is in flight; the reasoning select did not, so a second PATCH
could race the first and one change could be lost.
The model fields carried the form label's colon and the lookback picker
an uppercase section-style label and a fit-content 36 px trigger. All four
fields now share one unadorned label and the full-width 44/40 px control.
The operator's shared Codex is appended to the resolved chain but is never
a chain entry, so the Coach's provider select had no option for it and
showed its first option as the one answering. The answering provider now
appears as a disabled option, with a note that the operator manages the
connection.
The provider-chain summary marked every entry available, so the Coach's
provider select offered entries without a key or sign-in. Choosing one
saved it to the front of the chain, the resolver skipped it, and the
select jumped back without a word.
Availability now comes from the presence probe, which names every chain
type whose credential is present. After a switch the picker reads the
chain back and says so when the server still answers with another
provider.
The saved Coach window only seeded the snapshot and each tool's default.
A tool could still read back to all time, the availability probe reported
counts and means for history outside the window, and several blocks read
fixed windows of their own (labs 12 months, correlations 180 days, the
coarse tail, the all-time extremes) whatever the setting said.
coachPrefs.defaultWindow is now enforced as a limit through one module,
history-reach.ts: the turn context clamps the client window, the snapshot
clamps its window and gives every fixed-window block either the shorter
window or, when the block's own window cannot fit, leaves it out. Every
retrieval tool clamps its window, an earlier period or a stored table that
reaches past the limit answers outside_reach, and the probe reads only
inside the limit and names older history as outside_reach without any
figure. Follow-up chips that would read past the limit are not offered.
The default (allTime) is no limit and reads as before. MCP clients pass no
limit and keep their own window arguments.
Adds the twelve-month option, rewrites the picker text to state what is
read with the numbers the readers use, shows the same options in the
managed-profile settings, counts cluster members with a singular, and
drops the opacity on switched-off rows that put their text below WCAG AA.
Under an answer: copy, read aloud, try again and the time as text on the
left; tokens and model on the right, on one line down to 390 px. The
thumbs leave the web (the feedback route stays for the native client),
and so does the "What I'm looking at" disclosure: the method line and
the tables the answer read move into the steps list, and an older
message without steps lists the areas it drew on, never a raw key.
Remember becomes a bookmark icon in the question's row and confirms in
place with a toast. Follow-up chips render inside the latest answer's
column at its text size. The answer column takes the full width below
`sm` and a fixed 80 % above, so nothing moves sideways as a reply
streams. A round button fades in when the thread is scrolled away from
the end and brings it back.
The Coach page gets a conversations panel on the right of the thread. From
1280 px it docks beside the thread and slides open and shut; the reading
column keeps its width either way and only its centring moves. It is open
on a first visit and remembers the last choice per device. Below 1280 px it
is a sheet from the right. The toggle sits at the trailing edge of the top
bar, through a small page-owned slot the top bar now renders.
The panel lists every conversation grouped by recency, with a row menu to
rename in place (Enter saves, Escape cancels without closing the panel) and
delete with the existing undo toast. The undo window now survives the sheet
closing. New chat is the round button at the panel's bottom right, and
picking or starting a conversation keeps ?c= in the URL.
The gear in the panel header opens quick settings: a popover from md up, a
bottom sheet on a phone. It switches the answering provider (chain reordered
through the existing route), the model and reasoning level where the person
owns them, and shows what the Coach can see. Keys, the Codex sign-in and the
fallback chain stay in Settings > AI. The drawer's gear opens the same
overlay. The composer's + menu is gone.
Settings > Coach links to /coach?settings=data, which opens the overlay on
what the Coach can see instead of a rail that no longer exists.
Both grids carry an aria-label while their data loads, on a plain div,
which axe reports as aria-prohibited-attr: the label has no role to
name. A scan that lands while the scores strip is still loading fails on
it. The loading grids now take role=status, the role a loading region
has and which already implies the polite live region; the loaded vitals
grid carries neither.
Entering the Insights overview fired every section's reads at once, about
two dozen requests on a seeded account, and the server worked through
them in a queue: the hero and the first sections waited behind trends,
the period review, cycle, signals, rhythm events, health status,
breathing, labs and ECG, all far below the fold.
The first three sections in the account's own order still mount with
the page. Every later one renders a 1 px sentinel until it comes within
400 px of the visible area of the shell's scroll container, then mounts
and fetches; once mounted it stays. Measured on a seeded account under a
4x CPU slowdown: 24 -> 13 requests on entry, the entry network span
1.3-1.8 s -> 0.5-0.9 s, LCP about 1.35 s -> 0.9 s, blocking time about
550 ms -> 200 ms. Scrolling to the end still loads all 25 and renders
all ten sections.
Specs that assert on, measure or scan the lower sections scroll them in
first through a shared helper, so their coverage is unchanged.
The health score card passed the episode onset, an ISO instant, straight
into its sentence, so it read "Rest Mode active since
2025-08-04T09:55:00.000Z". It now shows the day that instant falls on in
the profile timezone, in the user's date format. The test that pinned the
raw value now pins the formatted day.
Day keys anchored at noon UTC went through the zone-aware
dateShortSmart, which shows them as the next day in UTC+12..+14. A
dateShortSmartCalendar formatter reads the key in UTC with the same
year rule, and the predictions panel, the illness timeline, the
intraday pulse day label, the nutrient chart and the coach result
chart use it. The lab chart dates a date-only reading by its calendar
date and a timed one in the reader's zone, as the lab lists do. The
timezone formatter guard now fails on a noon anchor handed to a
zone-aware formatter.
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
per opened form, so a second tap lands as a duplicate, not a second row.
The workouts page carries the action in its header and in the empty
state; the detail page offers delete for a hand-entered workout.

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.
Refs #1084
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.
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.
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.
Refs #1067
A guard that compares a sweep against an allowlist, or against "none of
these may exist", passes when the sweep comes back empty. walkSourceFiles
already refuses a short walk; this adds the same refusal for what a guard
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).
- tone harness: assessment prompt modules (11).
- coach locale default: turn pipeline modules (15, floor 12).
- locale integrity: message bundles (7).
- settings card header coverage and settings anatomy: the walked cards.
- coach metric scope inventory: insight route sources.
- side-effect drift guard: both enums populated, since two empty keysets
are equal.
The pill-mapper guard walked with globSync, which skips dot-prefixed
directories; it now walks through walkSourceFiles like the rest.
The narrative, the workout distance and the elevation chart converted
through the unrounded escape hatch, and the trend caption scaled its
noise floor off the raw factor. They now take the rounded helpers, so a
narrated pound or mmol/L figure reads at the grain every screen shows
it, and the caption's floors are declared canonically (the distance
floor in metres). The trends row joins the chart-feeding surfaces that
may hand a raw scale to a chart.
Refs #1067
Two more surfaces carried a fixed unit. The insights trends row labelled
weight in kg and body temperature in °C for every reader, and plotted
walking distance as raw metres under a km label; its trend caption
said the same. A single transformed series there now takes unit, scale
and offset from the preference, and the caption describes the converted
series against a converted noise floor.
The illness day sheet and timeline showed and took a fever in °C. The
fever is now seeded, typed and shown in the reader's temperature unit
and stored in °C as before.
Refs #1067
The workout list, the detail header, the stat tiles, the sport-average
line and the elevation chart printed kilometres, minutes per kilometre
and metres for every reader. They now read distance, pace and elevation
through the unit registry (km or mi, /km or /mi, m or ft). The splits
table keeps its kilometre rows, which are cut server-side, and says so.
A pace that rounded to sixty seconds now carries into the minute.
Refs #1067
The settings threshold editor took the identity path for the glucose
thresholds, so an account on mmol/L was shown a mg/dL default and asked
for mg/dL figures against 40-400 bounds, while the insights sheet for
the same threshold already spoke mmol/L. The shared target adapter now
owns the glucose unit as it owns pounds: fields, inward-rounded bounds,
the default hint and the canonical write all go through it, and the
insights panel and its sheet use the same branch instead of their own
conversion.
Refs #1067
The persisted copy of a streamed reply used to mount as a new bubble, so
what the reader had done on the streamed one (the chart or table view, the
open steps list, the evidence panel) reset when the conversation refetch
landed. A turn now keeps one key from its first streamed frame to its
persisted copy, both render in the same wrapper, and the copy keeps the
live tables instead of refetching them, so React keeps the one bubble.
The wrapper stops being a live region once the turn is settled. The
150 ms twin-hiding window this replaces is gone.
