The app carries three scores and meant two things by a green dot.
Readiness and the sleep score both call 70 green; the health score alone
wanted 75. One app cannot do that, so the outlier moved. The yellow floor
stays at 50: raising the bar for a reward and lowering the bar for a
warning are different decisions, and only the first one was on the table.
The band is still not a function of the number. The composite takes the
worse of the mean's band and the worst counted pillar's, so a composite
carrying a red pillar stays red however high the mean sits - the stored
band on a recorded day exists for exactly that reason. Only the mean-side
thresholds moved.
The method version moves with it. A day already recorded keeps the band
it was actually shown under, and the notice key carries the version, so
each account is told once that the rules moved. The week-over-week
comparison is left alone on purpose: the number itself does not change,
only the colour it is drawn in, so a subtraction across the change still
compares two numbers worked out the same way.
Under a number, 'Just in' did not say what had arrived - the score? a
reading? - and the clock face beside it changed nothing a person would
then do. The line is gone, and with it the only wall clock this surface
rendered.
What it was there for survives: the day still flips in place when last
night's sleep lands, and the pending-night note still says the number is
reading an incomplete day. An arrival on its own is no longer a reason
to paint a hero at all, so an account whose only news was the arrival
now gets nothing rather than a bordered empty card.
The digest still carries the arrival, which the morning line and the
wide event both read.
Save moves out of the header and into its own row at the bottom right,
where every other settings card that saves a form puts it. The body
starts on the title's reading edge instead of the card edge, so the text
lines up with the cards above and below it.
The rules between the rows are gone; the gap between groups does the
grouping. Every row said 'Being recorded - Shown in the app' under the
pillar name, which is the modules screen's business and was the same two
words on every line - the sentence at the top of the card already says
it once. The paragraph explaining that heart, glucose and cholesterol
are three pillars in one area is gone too.
The area headings read in the content colour now rather than the muted
one, so they stop looking switched off beside the rows they head.
It could never score. The schema records VO2max but cannot tell a
measured test apart from a device estimate, so every fitness row reached
the scorer unproven and was refused - the pillar has never produced a
value on any account. Listing it on the score settings page as a thing
you can choose, with a line admitting it does nothing, was chrome over a
switch that changed no number.
So it leaves the catalogue: no pillar id, no domain, no scorer, no row,
no wire field. A stored selection that still names it reads back fine -
the resolver has always filtered stored ids against the catalogue and
drops what it no longer knows, so nobody's saved recipe throws or is
discarded over it.
That also fixes the page claiming unsaved changes forever. The save
stripped the fitness pillar out of the selection on its way to the
server, so the answer that came back could never match the form that
sent it, and 'All pillars' left the save button lit no matter how often
you pressed it.
The new page wrote its own success toast. The outcome module owns that
affordance so a saved thing looks the same everywhere, and a structural check
catches anyone reaching around it. That check offers an allowlist entry as a
way out; taking it would have left two places deciding what a success looks
like, which is the thing the module exists to prevent.
Two branches met here. One made `configured` a required field so a caller
cannot stay silent and publish "not authored" for an account that chose its
own composition. The other wrote these cases before that existed, so they
compiled against the old shape and stopped compiling against the new one.
Filling the field in to satisfy the compiler would have thrown away the point
of making it required, so each case now states what it actually is: the two
with a hand-picked selection are authored, and the one whose own comment says
the account counts all eight is the default.
The composite's coverage counts distinct areas of health, not pillars.
The learning line called them pillars, so an account recording blood
pressure, glycaemia and cholesterol read that it had one eligible pillar
while three sat in front of it. The count was right and stays; the noun
was wrong.
The meter beneath the score carried the same confusion further. Its
fraction is the three-area minimum the score requires, and a score only
exists once that floor is met, so it rendered as full coverage for every
account that has one. The arithmetic is untouched. Below the floor the
fraction is a real number and is shown as one; at or above it, the floor
is stated. The dots and the percentage were always honest, they track how
much history is behind the number, and they stay.
Both are held down by an AST guard rather than a text search, with a
counter-test for the neighbouring lines that are legitimately about
pillars and legitimately about a real fraction.
The flag was proven end to end over the real snapshot, digest and derived
wires, which is the right place to show that it arrives and the wrong place
to be the only proof of what it means. That suite needs a container runtime,
so on a machine without one the definition stood unguarded: replacing the
default side of the comparison with the unnarrowed catalogue, the exact
mistake the docblock warns about, left the whole unit suite green.
The definition now has its own fast test, and that break takes two of its
cases red.
A dedicated settings page lists every scorable pillar grouped by the area
of health it speaks to, so the fact that blood pressure, glycaemia and
lipids are three pillars of one area is visible rather than buried. Each
row shows the three things that were never separable before: whether the
pillar is being recorded, whether it is shown, and whether it counts
toward the score. Only the last is writable here, and the page says so.
A pillar whose tracking is switched off is not listed at all, because it
is not waiting for anything. A pillar this build cannot score yet is
listed, disabled, and says why. Wellbeing under safety signposting is
named as safety guidance and never as a mistake in the selection. The
refusal for a selection too narrow to produce a score comes from the
server and is shown in the reader's own language.
The score's foot disclosure gains one link into the page.
Two sentences about the Health Score stopped being true the moment
someone could choose which pillars count toward it.
The one people read said the score averaged "every pillar that has
enough recent data". For an account that took a pillar out, that
describes ground the number does not cover, and it reads as a
reassurance rather than a description. It now says the average is over
the pillars that count, that a pillar without recent data is still left
out rather than zeroed, and that which pillars count is the reader's own
choice, so the combined number is not itself a clinical standard. All
six locales.
The one nobody reads named the WHO HEARTS technical package flat, as
though a standards body had signed off on whatever selection the account
holds. HEARTS names the risk factors the pillars are drawn from; it
prescribes no average over them. The entry now says what it is cited
for. While checking where that citation surfaces it turned out it
surfaces nowhere: ProvenanceExplainer takes the prop and renders only
the method caption, which v1.22 did on purpose when the info popover
went away. That is written down in the file now, because the map's own
header implies otherwise and the next person would trust it.
The registry entry for HEALTH_SCORE lists all eight pillars with a
minimum of three, which reads like the recipe and like a threshold. It
is neither. The published coverage and confidence are built in
computeComposite over the resolved composition, so a person counting
four pillars is not measured against a denominator of eight, and the
real floor is the breadth rule, which counts distinct domains rather
than inputs. Both facts are now stated at the entry instead of being
inferable only by following the call chain.
Tests: the published denominator is never the eight-pillar catalogue; a
pillar somebody took out of their score is never listed back as missing
coverage; a pillar they kept and have no data for still is; the registry
list stays equal to the score catalogue; the choice sentence is present
in all six locales.
One line under the method version, shown only when the server says the
composition is the person's own. It states the fact and stops there:
which pillars they took out belongs to the settings surface, and
working it out here from a configuration blob would put a second
decider behind one sentence.
The dashboard snapshot copies it off the composite, the daily digest
copies it off the snapshot, and the derived-metric payload already
carries it inside the composite value. Optional on both DTOs like the
score identity fields beside it, so older cached bodies stay valid.
The digest's score object is additionalProperties:false and had never
declared deltaReason, scoreVersion or composition, all of which it has
been sending. A generated strict decoder would have rejected the real
payload, so they are declared here too rather than left standing next
to a field that documents itself correctly.
One boolean on the composite: true when the account's resolved
composition differs from the composition its defaults would resolve to
today, both narrowed by the same modules. Decided once in the score
reader, from the same config and module map the composition came from,
so no client interprets a config blob to answer it.
This is not hasSelection. An account that opened the surface and kept
every pillar has written a selection and is not configured; an account
whose modules alone narrow the set has authored nothing and is not
configured either.
The promise is that nobody's number moves the day they upgrade, and the
way it holds is easy to lose: there is no backfill and no migration
step, because a null column reads as version zero, version zero counts
every pillar, and every pillar narrowed to what the account's modules
record is exactly the set the module switches were producing before.
The inheritance is the resolver's behaviour, so the next person to touch
the resolver needs to know they are holding it.
Also records what the first save sets in motion, once each: the delta
suppressed while the comparison window still straddles the change, the
next stored day marked as a break so the line is drawn in two segments,
and the notice raised under a key carrying the recipe version.
The recipe boundary opened with an early return for a missing date and
another for a date it could not read. Deleting either one changed no
answer any test or any caller could observe: both cases parse to NaN,
and every comparison against NaN is already false, so the refusal was
falling out of the arithmetic underneath them. An if that cannot change
an outcome is a comment wearing a keyword, and it invites the next
reader to trust a lock that is not attached to anything.
The behaviour is unchanged and now has one statement instead of three,
with the reason written where the next person will look for it.
The seam had the same shape in miniature: a day naming no recipe was
already broken away from a day that named one, by plain inequality, so
the arm only ever mattered when two consecutive days both named none.
That case is now covered, and removing the arm makes it fail.
The recipe boundary also required a version of at least one before it
would suppress. That reads like a second lock and is not one: the
resolver returns a version below one only on the same path that returns
no change date, so nothing could ever reach the condition and no test
could make it fail. Removing it leaves the guard asking the one question
that has an honest answer, which is whether the recipe moved inside the
window.
The invariant that makes the removal safe is now pinned instead: a
resolved configuration never carries a version without the date beside
it. A resolver path that produced one would wave that account's recipe
change straight past the guard.
Also pins the order of the two rules that can fire together. A change
that moved the composition trips both, and the person is told they
changed what counts rather than that the included pillars changed, which
would describe the consequence and leave out the act.
The named failure now has a test that drives the whole chain a request
takes: fixture rows through the real reader, the real score record
write, the real dashboard snapshot, the real verdict rung, and the real
digest that gives the morning push its sentence. Only the IO around that
chain is faked. A version built on a hand-written snapshot literal would
have stayed green through a release where the assembly between the two
ends dropped the field, which has happened here before.
Every case runs twice on the same data. Once with the recipe changed
three days ago, once with it changed a month ago. The second run is what
proves the fixture really does produce an eleven-point fall, so the first
run's silence is the guard working rather than an account with nothing
to say. The decline is gradual on purpose: a cliff would raise each
pillar's own noise floor and the delta would be suppressed for a reason
that has nothing to do with the recipe.
Beside it, the boundary's edges, the notice key's two dimensions and the
seam's shape, each with a case proving the guard stays quiet on innocent
data. Against real Postgres, a row now has to come back carrying the
recipe version and change date the account's stored configuration
supplied.
Changing which pillars count is an act the person performed, not
something that happened to their health. Until now the week-over-week
comparison could not tell the difference: both windows are computed in
one request under whatever recipe is in force right now, so the pillar
sets agree, the subtraction looks legitimate, and the dashboard could
announce "your score dropped 14 points" to someone who had just come
back from the settings page.
The recipe now carries its own dated identity, and the delta guard
compares against it the same way it already compares against the global
method boundary: a recipe that changed between the two windows
suppresses the delta with a new reason, config_changed, and the surfaces
that gate on an unexplained delta stay quiet. The score record stores
the recipe version and its change date on every write, resolved from the
same stored blob the composition came from, so a row can say which
recipe produced it. A new series module reads those versions back, marks
the first day after a change as a break, refuses to join the composite
line across it, and keeps the per-pillar rows running through it: a
pillar is graded against its own reference band and stays comparable
when the average of the pillars does not.
The notice key folds the person's recipe version in beside the method
version, so a change in either raises the existing dismissible notice
once and dismissing one never dismisses the other. An account that never
chose keeps its old key untouched.
The module-to-pillar mapping had no test of its own. It lived in
ternaries, so the only way to notice it had changed was for someone's
score to change.
The new file drives the real reader against a fake database and pins
three things. The composition for every module combination with no
stored recipe, compared against the old expression written out verbatim,
which is what makes it a before-and-after rather than a restatement. The
difference between a pillar that is selected and has no data yet, which
keeps its row, and a pillar whose module is off, which has no row at
all. And the breadth refusal at read time, whose reason has to be the
shared rule's verdict on the set the reader resolved, so a second copy
of that rule would show up as a disagreement.
Until now the set of pillars behind the Health Score was assembled from
the module switches alone, in a stack of ternaries inside the reader. A
person who turned the sleep module off lost the sleep pillar from their
number as a side effect of a setting about recording data, and there was
nowhere else to say what should count.
The reader now reads the stored recipe and narrows it to the pillars a
module is actually recording. The mapping from module to pillar moves
out of the ternaries into a named map beside the reader, where it can be
read and tested. Glycaemia stays fed by either glucose or labs, which
was the one entry a one-module-per-pillar map would have lost.
Nobody's number moves on upgrade. An account that never opened the new
surface resolves to every pillar, and every pillar narrowed by module
availability is exactly the set the ternaries built, so the inheritance
holds by construction with no backfill.
A pillar the recipe selects whose module is off produces no row at all,
rather than a "waiting for data" line. Turning a module off is a
deliberate act, and asking someone for data they chose to stop recording
would be nagging them in the voice of their own settings.
The delete-all-data guard seeds every table straight from information_schema
so a table added next year is asserted without anyone remembering. A CHECK
constraint defeats that: the generic seeder has no way to guess a value the
constraint accepts, and the whole suite failed on the new table. A Postgres
enum carries the same closed set, the seeder reads it from pg_enum, and
Prisma now types the column instead of trusting a string.
Dropped the day-key format and non-empty-composition checks with it. The
writer builds the key through the timezone helper and refuses an empty
composition before inserting, and the restore validates both against the
wire schema before the transaction opens, so a third copy in the database
bought nothing and cost a hand-written line in a fixture whose point is not
having one. The composite range check stays: free to check, and a number
outside nought to a hundred renders as a score nobody can read.
The scorer and the stored composition both had to answer what a valid
pillar list looks like, and both had their own copy of the answer. One
function next to the catalogue now, used by both.
Four suites hand-roll a Prisma stand-in for the backup builder, so a new
section reaches them as an undefined delegate rather than as an empty
result. Each gains the delegate, and the admin restore round trip gains an
assertion that the day comes back with its composition and per-pillar
scores, not just its headline: a row restored without those looks restored
and answers nothing.
A new user-scoped table is outside all three by default, and the two
structural guards said so the moment the model landed: the wipe plan and
the backup verdict list both named it as unclassified. It now joins the
wipe list, rides the backup payload as its own spread section, and comes
back through the restore route.
The classification guards only prove a helper exists in a declared file, so
they would pass an unreferenced restore helper. The integration round trip
goes through the real admin restore route instead, with the table emptied
first so a restore that carries nothing cannot pass by leaving what was
already there.
PATCH /api/auth/me/health-score-config takes the pillars a person
wants counted and stores the rest as the deselection list. A selection
that cannot produce a score is refused with a sentence naming what is
missing, using the same rule the scorer applies at read time. The
write evicts the score caches, and so does the modules route, which
changes the same composition and never did.
The fingerprint carried the composition twice: once as its own key and once
as the ordered pillar ids inside the per-pillar triples. No input could make
those two disagree, so the term could not be broken and the test that
claimed to cover it passed with the term removed. Dropped the duplicate and
replaced the test with one that pins what the ids are for: a different set
of pillars producing the same numbers in the same order is a different
standing, and now reads as one.
Reads the stored deselection list into the pillar set the scorer and
the settings surface both work from. An absent list means the person
never chose and keeps counting everything; a present list is an
authored recipe and is never widened. Ids outside the catalogue are
dropped on read rather than failing the whole blob, so one unknown
string cannot discard a recipe someone wrote.
Every surface that shows a score now goes through one entry point that
computes it and writes the day down, rather than three surfaces each
remembering to. The write is an insert that yields on conflict, so a second
computation of the same day leaves the first row alone, and a failure is
annotated rather than thrown: a score that renders must not disappear
because a bookkeeping insert did.
The fingerprint covers exactly what the stored composite and band depend on
- the algorithm version, the composition, and each counted pillar's score
with its scoring-mode identity. A pillar that was graded but not counted
stays out of both the fingerprint and the row, because it did not
contribute to the number being stored.
The composite needs three distinct domains and one physiological
pillar. Until now only the scorer could narrow the pillar set, so the
rule lived inside it. A settings write can narrow it too, and a second
copy of the rule would drift, so both layers now call the same
function over the same pillar-to-domain map.
The panel picked up a green +N chip beside its label when the score moved
back into the band, and the repo-wide affordance guard counts that colour
wherever it appears outside the outcome module. The chip reports a week that
went up rather than an action that succeeded, so it is recorded here at
exactly one use rather than routed through the outcome table.
The sideways check could not fail for the case it was written for. A panel
wider than the phone kept it green: the hero band wears overflow-hidden for
its glow, so an over-wide panel is clipped rather than scrolled and the
document never widens by a pixel. The person loses the right-hand end of
every row and nothing reports it.
It now compares the panel with the room the band actually offers, which is
the comparison the clipping makes meaningful.
The reserve and the row's label column were carried as comments with pixel
figures nobody could reproduce: the tool that produced them was never
committed. This adds one that is, and the figures change.
The reserve did not hold anything. Its declared minimum was 30rem while its
own blocks added up to more than that, so the height was whatever the blocks
happened to be and the constant was decoration. The blocks are back under the
floor and the floor is 28rem, which sits between the shortest and the tallest
panel a real report produces: three scored rows come to 410 pixels at the
352 pixel column, four 438, five 466, six 494, and the reserve is 448. A short
report is no longer pushed down by 74 pixels when the score lands.
The label column goes back to the 7rem the design specifies. It had been
widened to 8rem on the grounds that 7rem clipped the longest label in five of
six languages and 8rem cleared them; measured, the longest label overruns both
widths in five of six, and the only difference is English, by a margin smaller
than the error introduced by measuring in a substitute typeface. The extra
width came off the fill bar for nothing.
The new check renders the real band with the compiled stylesheet and reads the
boxes back in a browser: the reserve against the panel it stands in for, every
row in all six languages on one line with an ellipsis rather than a push, and
no sideways scroll at the 352 pixel column or at 360 pixels stacked. It states
plainly that it cannot know the shipped typeface, since the font is fetched at
build time and no font file is committed, so every assertion in it is one that
holds in any typeface.
Four things a person notices if they break: a pillar never shows up twice
anywhere in the panel, a failed read never lands in the not-scored list, the
panel does not push the page sideways at 360 pixels, and the whole thing is
there with the briefing switched off. Every one of them was broken on purpose
first to check the test actually goes red.
The label column is 8rem, not 7. Rendered in all six languages, 7rem clipped
the longest label in five of them, two of those by two pixels, which reads as
a bug rather than a truncation. The reserve is 480 pixels, measured against
the built panel rather than guessed: three rows come to 440 and six to 524.
The overview fixture now carries a health score, so the phone-width guard
measures a band with the panel in it instead of an empty column.
The stand-in for the discovery engine took an argument it never read, so
the lint run flagged it. Give the mock a function type instead: the
argument stays inspectable, which is the whole point of the probe, and
nothing is declared and then dropped.
The grader returns the score and its basis together and the pillar builder
copies both across, and each of those ends already had its own test. Neither
sees what happens between them: the envelope hand-off, the reader's narrowing,
the pillar list, the JSON that finally goes out. A field can be produced
correctly, consumed correctly, and never reach anyone, which is exactly how a
payload field shipped earlier this month and carried nothing on the wire.
These tests read the assembled response and assert the basis that arrives, so a
future hand-picked key list on that path fails here rather than in someone's
browser.
Three lines now sit above the reference band: which axis set the number
and how far it was from its ceiling, what the scale means at the ceiling
and at 100, and that the pair shown is a recency-weighted average rather
than a reading anyone took. In all six languages.
The guard read a parameter as required whenever it carried no question
mark and no default, so `Locale | undefined`, `Locale | null`, a locale
widened to `any`, and a default sitting on the destructuring pattern all
walked straight past it. Each of those lets a caller say nothing and the
sentence come back in English, which is the bug the guard exists to stop.
A counter-case pins the other direction: a plainly required locale still
reads clean, so the guard stays quiet on the shape the chain is meant to
have. The correlation read now also asserts the language it was asked in;
nothing else in that file would have noticed it going back to English.
The score popover now opens with three sentences before the reference
line: which axis set the number and how far it sat from its boundary,
what the scale means at that boundary, and that the pair behind it is a
recency-weighted average rather than a single reading someone took.
The lines read the basis the grader already publishes, so nothing here
recomputes anything. A pillar that arrives without a basis contributes no
lines at all instead of an empty one.
The score is the worse of the systolic and diastolic sub-scores, and
until now nothing said which one it was or how far over its ceiling the
reading sat. The grader now returns that basis together with the score,
as one value, and it is carried as one value all the way to the pillar
so an explanation can never belong to a different grading run than the
number it explains.
The score returns to the right-hand column of the hero band, where it sat
for eleven weeks: the number at the top, then one thin line per pillar that
actually counts toward it. The card that was pinned below the greeting is
gone, so the score has one place on the page again.
Each contributor line now takes its own colour. A pillar scoring 92 used to
be painted red just because the overall score was red.
Anything not contributing is one quiet line instead of a block: a failed
read is named once for all the pillars it took down and carries the retry,
safety guidance is named in full, and everything simply not recorded yet is
counted, with the names a tap away under the score.
Three things are held down here. The route hands the reader's language to
the strip builder, for a cookie and for a stored preference. The pattern
sentence comes back in German for a German reader, asserted word for
word, through the real chain rather than the engine on its own — the
engine could always write German, it was simply never asked, so an
engine-only test would have stayed green the whole time it was broken.
And a cached strip stays with the language it was written in.
The guard reads the declarations rather than grepping them, so renaming
the argument or moving the fallback into a variable does not slip past
it. Its counterpart runs the same detector against those disguises and
insists each one is caught, because a check that cannot fail reads like
proof and is not.
On a German metric page the strip printed its own summary in German and
the pattern line under it in English. The pattern line is a finished
sentence the server writes, and the route never told the server who was
reading, so it wrote English.
The route now resolves the reader's language the same way the
correlations and analytics routes do and passes it down. The language is
a required argument the whole way through — it used to be optional with
an English fallback, which is why a caller could stay silent and still
get a sentence back. The cycle page's lagged rows had the same gap and
are fixed with it.
The strip's browser cache is keyed by language too, so switching
language no longer re-uses the sentence written for the previous one.
