It gates the flag the forecast publishes, so a surface asking whether the
history supports a weekday claim about THIS comparison asks one place.
It does not retro-gate the weekday board the insights page has carried
for releases — that board is built from the entry aggregates and has its
own floors, and hiding it from accounts under ninety days would take a
surface away from people already reading it to enforce a rule about a
different calculation. And it does not justify building a second one.
Two small things the first pass left rough.
The fit's window read had no row cap. A year holds 365 days and the fold
keeps one entry per day, so the cap only bites on an account that logs
many times a day — but an unbounded read in a nightly job is a table
scan waiting for the account that has years of history. The rows now
arrive newest first under a cap, which also puts the loss on the right
end: an account over the cap loses its oldest days, never the recent
ones a forecast is written for.
And the card showed the raw day key. It goes through the account's own
date-order preference now, pinned to UTC like every other day key in the
app, so this card cannot show a different day from the list beside it.
Every delegable operation states, in the contract, that it can refuse a
delegate — and the guard over the document caught this one publishing
only its module gate. One status, two reasons: the module gate's own
sentence first, the shared refusal spliced on the end, which is the
shape every other gated delegable route already uses.
The snapshot gains the day's two readings with the age of the second
one, through the same reader the page uses, so the page and the
assistant cannot disagree about what today's comparison is. The
freshness rule is the shared one: a comparison about the day before
yesterday carries the date it is about and an instruction not to state
it as today. Absence is a present field rather than a missing key —
a model told "there is none yet" says so, and a model told nothing
estimates one. The wording rule travels with the values, because a model
handed a number and no instruction writes the sentence its training
suggests, and about a forecast that sentence is a causal one.
The contract publishes the resolved value: the expected figure, the
band, the count, the deviation against the band, the age, and the
contributions that carried weight. Nothing is left for a client to
re-derive — two clients deriving the same figure about somebody's health
record is how they start disagreeing about it. The description carries
the observational wording and the display rule: the count goes wherever
the value goes.
The end-to-end proof runs against real Postgres and reads the table
rather than a return value: nothing written a day short of the
threshold, a banded and counted row on the day it crosses, the
provisional label dropped at sixty days, the rows cleared when the
module goes off, the rows cleared when entries are deleted back below
the threshold, and an older pass's row replaced rather than left beside
a fresh one. A delegate holding only the mind section is refused, and
the assertion is on the response bytes.
Two readings, side by side, never merged. The person's own rating leads
— larger, first, and returned exactly as it was stored — and the
comparison sits beside it with its range and the number of days it was
built from. The deviation is measured against the range, not against its
midpoint: inside it is a day that went as the account's own past days
suggest, and only outside it is worth a sentence.
The sentence is a counterfactual and says so. Never "your mood is 5.4",
always "a value around 5.4 would have been expected". The explanation
names what the comparison weighted for that day, out of what the job
stored for that day, in the words the capture sheet already uses — a
person reads "Workload" here because that is what the slider they moved
was called.
The route declares the whole record rather than the mind section, and
the reason is written at the declaration: the comparison reads the day's
context AND the figures the sleep, activity and recovery modules hold,
and it names them, so a delegate holding only the mind section would
receive a derived view of sections the owner declined to share. A scoped
grant is refused outright rather than served a contribution list with
the linked features quietly removed, which would read as "only the mood
fields mattered" and be false.
The causal-verb ban is a test now rather than a review habit: the copy
guard reads all six bundles and fails on a causal construction in any of
them, and on a statement that quotes a value without the days behind it.
Both halves were watched failing.
A job, never a route. A forecast written as a side effect of opening a
page is a function of browsing rather than of data, and the prognosis
also has to be a value the person cannot overwrite — so one file writes
the table and a guard holds it there.
The cohort is the union of two sets and the second one carries the
weight: accounts with enough recent rated days, plus every account that
already holds rows. Without the second, an account that deleted its
entries would fall out of the sweep and keep last month's answer under a
fresh-looking date, with nothing on the surface to say so.
A pass replaces rather than accumulates. Every account it touches ends
holding exactly the rows that run wrote, or none: below the threshold,
module off, no pattern in the data, no recent day carrying everything
the fit needs — every one of those clears what was there. Per-account
failures are counted and the pass continues; only an all-accounts
failure fails the job.
Runs at 04:35, after the inputs have settled and clear of the geo
backfill on the hour's fortieth minute. The arithmetic is a ridge
regression and nothing else: no provider, no key, no egress, no consent
gate, and the module says so at the top so nobody wires one that does
not apply or assumes one that is not there.
The target is the day's own pleasantness; the inputs are the other four
self-ratings, the numbers and closed vocabularies of the day's context,
and the figures the sleep, activity and recovery modules already hold.
Nothing is imputed. A day missing one of the selected inputs is a day
the fit does not see, and a feature nobody recorded on most days never
becomes a column in the first place — the coverage floor is what keeps
the complete-case rule from quietly emptying the matrix. A day with no
context row contributes no work-status column at all, rather than a zero
that would read as "worked a regular day".
Columns are standardised against the account's own window, so a person
whose stress never passes six does not have six read as the maximum.
Candidates are screened with the machinery the rest of the product
already runs — Pearson at the shared paired floor, Benjamini-Hochberg at
the shared FDR, the shared effect-size floor on the shrunk estimate —
because a sweep over sixty features at raw p < 0.05 finds three things
that are not there.
The fit is a ridge solved in closed form, validated on expanding windows
in date order. The training range ends exactly where the validation
range starts, asserted on the fold indices and on the day keys, not on
the resulting error: a leaking split passes an error check whenever the
leak is small, which is when nobody looks. The band is the central 80%
of the validation residuals, so it widens when the model is bad instead
of staying confidently narrow.
The window read is the linked resolver's own engine, extended to answer
many days in one query rather than growing a second opinion about what a
Tuesday looked like.
Five rungs — nothing at all below fifteen entries, descriptive hints to
thirty, a provisional forecast to sixty, a plain one to ninety, weekday
and seasonal comparisons above it — plus the occurrence floor a value
must clear before it may be named at all.
Every floor is an exported constant and every one has a test on both
sides of its own boundary, because the failure here is invisible: a
forecast built from eight days renders exactly like one built from
eighty, and nobody reading the screen can tell. Each assertion names the
threshold it is about, so a red says which floor moved.
Absence carries its reason and the count rather than being a bare false,
so a surface can say how far along the account is instead of showing an
error. Two numbers are deliberately not minted here: the paired-value
floor stays `MIN_PAIRED_N` in the correlations module, and the
occurrence floor is the crosstab's own, taken by assignment. A test
reads the file back and fails if either turns into a local copy.
`MoodPrediction` holds the expected value of a day beside the day's own
rating: one row per account per local day, with a band and the number of
days the fit used. Two tables rather than four columns on the entry,
because the point of the second value is that the person cannot correct
it into agreement with the first — the distance between them is the
finding, and a value the edit form can write is not a second reading.
The table stays out of the disaster-recovery backup and the reason is
written where the completeness guard reads it: every row is recomputable
from the entries, the contexts and the linked modules, and carrying one
would restore a forecast made by a model version that may no longer
exist against data the restore has just moved. It is in the wipe plan,
because a derived row is still a day-by-day statement about somebody.
The write-surface guard lands red on purpose and names what is missing:
`lib/jobs/mood-prognosis-refresh.ts` does not exist yet, so the writer
set is empty where it should hold exactly that one file. The job closes
it. The rest of the guard is green now — no route, page or component
writes the table, and the matcher proves itself against a call broken
across lines, an aliased client, a read and a different model.
/insights/mood was on its 460 KB ceiling. The route paints a calendar, a line
chart, a target card and an assessment; under them sit a dozen breakdown cards
— both tag axes, the influence board, the two crosstabs, the day-context
comparison, four Recharts mini-charts, the correlation cards — and every one of
them was a static import, so a cold mount paid for all of it before painting
anything.
The cluster is its own module now, loaded through next/dynamic with a skeleton,
the way the insights mother page already treats its below-the-hero blocks. It
takes the resolved aggregate as a prop rather than running a second query, so
it cannot draw a different snapshot from the regions above it.
The better-days card follows, for one specific reason: it resolves catalogue
tag icons, and that resolver statically imports about a hundred and sixty
lucide icons. The card sits a screen down and the map now rides the same lazy
group as the breakdowns.
Only mood-only modules moved. Deferring the shared target and assessment cards
was tried and reverted: it bought ten kilobytes on this route and cost
thirty-three on the whole-build total, because both are imported by a dozen
other insight routes and a route-local lazy group duplicates them.
/insights/mood 459 -> 451 KB gz (budget 460, unchanged)
total client JS 3296 -> 3297 KB gz (budget 3310, unchanged)
The payload shape and the section card frame move to a shared module both
halves import; the two structural tests that read the old file now read the
union of the two, so a guard cannot go quiet by pointing at the wrong half.
The six per-section type aliases and the inverse-orientation list had
no consumer; the schemas read the key arrays directly and the workLoad
orientation is stated where the rating fields are declared.
The hook always sent the browser's zone while the route's comment said the
detail view sent the entry's stored one. Nothing was red, because nothing
asserted it: correcting an entry logged in another country looked its day up
under whichever zone the correction was being made from, and the night shown
beside it could be hours out with nothing on screen saying so.
The edit dialog passes the entry's `tz` now. The capture sheet keeps the
browser's and passes no third argument, which is correct rather than an
omission: the entry does not exist yet and will be anchored to that zone.
A legacy row with no zone falls back to the browser's rather than to
Europe/Berlin — the server owns that legacy rule and a guess sent from the
client would override the one place it is written down.
The resolution is a pure helper so both branches can be asserted, and both
call sites are pinned structurally, because the resolution being right is
worth nothing if the dialog never hands it the entry's zone.
The doc comment beside `a1`..`a5` promised that an out-of-range value marks
THAT entry skipped and never the batch, while the fields sat in the batch
schema and answered 422 for all five hundred. The words were right and the
code was not, and a phone draining a year of local history lost the year to
one row.
The five now parse per entry, the same way the day context does; a bad row
reports `invalid_dimensions` and the rest of the batch lands.
The split buys the tolerance and costs a second copy of "0 to 10", so a guard
offers the same value to both schemas and makes them agree at both ends of the
scale and one step outside each.
The resolver hand-wrote the map and got it wrong in both directions. It gated
steps and active energy on `workouts`, which gates workout SESSIONS and not
ambient movement, so the mood sheet hid a figure every other surface shows. It
called resting heart rate and heart-rate variability core with no owner, while
the table has assigned both to `recovery` since v1.30.22 — including the RMSSD
fallback, pinned there so a ring-only account cannot reach through it. An
account with recovery switched off was served the domain it had switched off,
which made the release note's own promise false.
Both directions now resolve through `moduleForMeasurementType()`, the table the
MCP wire, the correlations reader and the Coach snapshot already share.
Steps, active energy and the two vitals also run through the canonical-source
picker now. Without it a phone and a watch reporting the same day summed twice
and the sheet showed a walk nobody took; the vitals answered whichever row was
latest rather than the picked stream's.
A guard pins the three ownership claims, including that the two vitals share
one module — the block carries one availability flag for the pair, so the day
they diverge that flag becomes a lie and the block has to be split first.
The route answered sleep minutes, steps, active energy, resting heart rate,
heart-rate variability and an illness day-log with its symptom keys, and it
declared `mind`. A delegate given only the mind section could walk arbitrary
dates through the one URL and read two sections the owner had declined to
share; no mood entry had to exist for any of those dates.
`record` is the convention for a read that crosses sections, and a scoped
grant never reaches one, so the scoped delegate loses the linked block rather
than receiving a filtered day. A block that silently dropped the sections a
grant does not cover would show a day that looks empty where the truth is that
it is none of the reader's business.
The reason is written at the declaration and in the frozen surface entry,
whose previous justification held only for whole-record grants.
Two requests can probe the same workout, both find no heart-rate series,
and both mean to attach one. The unique index on `workout_id` picks a
winner; the loser has to report the duplicate it turned out to be rather
than claim an attach the database never made. Nothing could catch that
arm going wrong: the unit fake echoes every row back as landed, and the
race suite carries no series at all, so replacing the status with a
constant `enriched` left the whole suite green. Two concurrent posts of
the same enrichment now assert one `enriched` against one `duplicate`
and a single stored series.
The published contract also says now what the counters mean, instead of
leaving it in a comment: an entry reported as `enriched` counts towards
`duplicates`, because the top-level counters count workout rows and an
enrichment writes none. Field descriptions on the response and on the
per-entry status and reason, OpenAPI regenerated.
Marking an older missed dose as taken from the Verlauf pinned the
right slot but stamped the intake with the current moment. The body
builder is a pure helper now, anchored on the slot instant, matching
both the optimistic paint and the skipped-to-taken flip that already
behaved this way.
Two entries carrying the same external id and both a `samples` array
reached the enrichment arm one after the other, and both read the same
landed workout id back, so the response claimed two attaches where the
database had written one. The second entry now takes the duplicate arm:
a workout is claimed by the first entry of the batch that reaches it.
A batch entry matching a stored workout stays first-write-wins for the
workout row. What it can do now is hand over a heart-rate series the
stored workout does not have yet: the series is attached, the row itself
is not written at all, and the entry reports back as `enriched`. A
workout that already carries a series is a no-op, so a client can walk
its whole history as often as it likes.
- The pre-flight probe now answers both questions at once, whether the
row exists and whether it already has a series, and carries the id so
the attach addresses the stored workout without a second round trip.
- The attach rides the same child write as a fresh workout's series.
RETURNING names the rows that landed, so a workout that gained a
series between probe and write reports as the duplicate it is instead
of claiming an attach that never happened.
- A `samples` array that fails validation is refused per entry with
`reason: "invalid_samples"` rather than failing the batch. One
unusable session out of a hundred must not stall a history sweep the
client cannot repair by retrying; every other validation failure keeps
failing the batch.
- The wide event and the audit row tally enrichments. Counts only, the
series never reaches either.
- `enriched` is the one contract movement: additive on the per-entry
status, request shape unchanged. OpenAPI regenerated.
Integration coverage against a real Postgres pins the attach, the
repeat as a no-op, the refusal of a bad series alongside entries that
land, a mixed batch reporting each status, and the stored workout row
compared whole before and after, `updated_at` included.
The page ended on a "Why?" button that opened the coach with a
prefilled question about the session. It leaves on the maintainer's
call; the coach remains reachable from its own surfaces. The two
strings it carried leave all six locales with it.
- the wipe plan names it before its parent, so the confirmation screen's count
is the number of rows that existed rather than zero
- the backup plan classifies it as carried and two-ended, and the round-trip
registry seeds one, which is what makes that claim provable
- the sharing surface admits the linked-day read with the reason it may answer
- CHANGELOG for the release
- /api/sync/changes carries a1 to a5 and the day context under the same keys
the write path accepts, so a client reads back exactly what it can post
- BulkMoodEntry accepts both, all optional; a1 stays server-derived from the
five-point label, so a build that sends only a label still writes a complete
row and needs no change to stay correct
- the batch parses each entry's context on its own: one row carrying a value
the vocabulary does not name is skipped and the rest of the batch lands
- docs/api/openapi.yaml regenerated alongside
- one comparison per context value, reusing the Welch test, the day floors and
the Benjamini-Hochberg family the tag board already runs; a wide sweep
filtered on a raw p < 0.05 would surface one-in-twenty noise as a finding
- two entries on one day count as one day
- every statement names how many days it compared, on the same surface as the
claim, and says it shows a connection rather than a cause
- the assistant snapshot carries the same rows with that constraint written
out beside them
- work, contacts, leisure and one notable event, each a closed accordion with
a count badge, on both the capture sheet and the edit dialog
- sleep, activity, vitals and the illness journal render read-only beside
them, each row naming where its figure comes from and offering a way in to
change it there
- the body line links into the illness module and captures nothing
- six locales for every label and every anchor
- one resolver reads the day's figures from the modules that own them; nothing
is copied onto the mood row, so correcting a sleep session corrects it here
in the same moment
- absence answers { present: false } rather than zero, because a night nobody
recorded and a night of no sleep are different facts
- a module switched off blanks its whole block instead of filtering down to an
empty one
- keyed by the local day so the capture sheet can ask before an entry exists
- the completeness guard now binds a third model, MoodContext, to a named
select; the four omitted columns each carry the reason the backup is right
to drop them
- the disaster-recovery arm carries the ciphertext, the portable arm the plain
text, and every other column rides in both
- the restore rebuilds the context after its entry, inside the same
transaction, and a file written before contexts existed restores without one
- the round trip asserts the restored row by value, zero included
- moodContextSchema derives every enum from the vocabulary, so a value it does
not name answers 422 through returnAllZodIssues rather than being dropped
- the context is written in the same transaction as the entry and its links; a
failure rolls the entry back rather than leaving a client retrying a 5xx
into a duplicate
- an entry with nothing filled in stores no row, and a context that says
nothing removes the one that was there
- the create, list, detail and edit reads answer the context with its lists
decoded and its note decrypted; the ciphertext never leaves the server
- one module holds the four sections, their key lists and the rating fields;
the Zod enums, the capture UI and the analytics all read it, so a value the
vocabulary does not name cannot be stored
- labels state facts, never judgements, and the contact circles are groups of
people rather than a score
- a pair guard binds the arrays to all six bundles in both directions, because
the reverse-coverage matcher sees a `mood.context.` template and stops being
able to tell a live label from a stale one
- migration 0311 creates mood_contexts, keyed by the entry, cascading from
both the entry and the owner
- work, contacts, leisure and one notable event; every field nullable, and an
entry with nothing filled in gets no row at all
- notes_encrypted registered in ENCRYPTED_COLUMNS and in the rotation script,
so a key rotation cannot strand it
The dead-code sweep found the window type exported and unread. It was
unread because the surface that offers the choice carried its own copy
of the same three numbers: the chart could not import the calculator's,
since that module reaches the database client two hops down and a client
component pulling it in would ship Prisma to the browser.
Both now come from the dimension table, which is pure by construction
and which the chart already imported. One declaration of 7 / 30 / 90,
read by the calculator that averages over them and by the control that
offers them, so the two cannot drift.
Three small things the audit named together.
The mood reads spread the whole row, so adding the wire keys shipped
every level-A value twice — once as the column name and once as the key
the write path accepts. A client would have picked one and been stuck
with it. The column spelling is stripped now, and the create response's
key set is asserted so it stays stripped. The published contract is
unaffected either way; these routes are not in it.
The dimension series carried its own copy of the day-key subtraction
that the freshness module already exports. One copy now.
And the reason a stale dimension ships with a notice instead of being
dropped the way the status surfaces drop one is written at the builder:
a one-line card has nothing left to say about a value it cannot narrate,
while an open conversation can say when the value is from — and silence
there would leave no way to tell an unanswered dimension from one nobody
has looked at in a week.
The snapshot stamps every metric block with an asOf built from the
newest reading in it, which for mood is the newest ENTRY on the 1-5
axis. Somebody who taps a face each morning and opens the sliders once
a week therefore carries a block stamped as current and a stress
reading six days old, and a reader taking the block stamp as covering
the dimensions states last week's answer as today's.
The block now names the precedence in one line beside the dimensions,
and each dimension keeps its own age. Present only when there are
dimensions to explain.
An entry always carries a five-point label, so it always implies a
pleasantness value: the create path derived one from a null and the
capture sheet still showed a clear control for it, which meant a button
the server undid on the way to the database.
One rule on both routes now — a null asks for a value that cannot exist
and gets the derivation, on create and on edit alike — and the control
is gone for that field. The other four are genuinely optional and keep
theirs.
Matches what syncVersion, syncedAt and the row stamps already do a few
lines above: a key the file does not carry is a key the file predates,
not a key the file says is empty. Reachable when one file addresses the
same row twice, where the second entry now adds without erasing what
the first one set; an explicit null still clears.
Worth stating plainly, because the audit that asked for this expected it
to protect live rows from an older file: it does not, and it cannot. The
restore deletes the owner's whole mood partition before it rebuilds, so
by the time the update arm runs there is nothing live left to protect. A
test now pins that contract too, so nobody reads the omission as a
guard it is not.
The single create's upsert restated all five columns on its update arm,
so a client re-posting an entry with only a label and a timestamp — the
phone, whose build has no sliders — cleared the stress, energy,
connectedness and stability somebody had answered on the web. The batch
and import paths already preserved them, so the two disagreed.
One answer now, and it is preserve: absence in a request means nothing
to say, an explicit null takes an answer back, and pleasantness still
follows the label because the request always carries one. The create
schema accepts the null that makes clearing expressible.
A re-post that omits a dimension is asserted to leave it standing, and
that assertion has been watched to fail against the old arm.
The inverse flag is read by the trend legend and by the assistant block;
the function that flips a value through it had no caller. It comes back
with the surface that needs a combined view, not before.
The pillar reads PHQ-9, GAD-7 and WHO-5 and cites the papers behind
every threshold. A daily self-rated slider is now available on nearly
every mood row, so leaving it out reads as an omission unless the
reason is written down: the two are different kinds of evidence, and
averaging them would weaken the line that makes the figure worth
showing to a doctor. Recorded at the pillar and at the columns.
