Readers that tag a cell as a closed block no longer import the
invalidation module, which several tests replace wholesale. The cache
route test counts the slice's pre-fold cell apart from the route's two
cells, and the provenance test reads the shared pick's ORDER BY over its
grouped rows.
Every sync marked all of an account's analytics cells stale, so the slice
re-read the pre-fold remainder (every reading older than five years,
folded per source and day, the slice's largest statement on a long
history) and the day view re-read its past history blocks, although a
sync of today's readings cannot change either.
A cache key can now name the instant its value's readings end before
(closedBlockKeyPart). invalidateUserMeasurements takes touchedFrom, the
earliest measuredAt a write created, changed or removed, and leaves such
blocks in place when it is not earlier; without it every block goes as
before. The batch route passes it from the identities it wrote. The
pre-fold remainder moves into its own module and is cached as a closed
block; the day view's past history blocks carry their end, with a day of
margin for a night across midnight.
The batch route's two up-front reads move into batch-stored-rows.ts with
the once-per-batch key rule they share.
The comparison history blocks were read with cache.get and stored with
cache.set, outside the single-flight slot that an invalidation fences.
A read that spanned a write cached the days from before it for the
block's whole TTL, and two concurrent reads of a block both queried.
Each block now goes through cache.wrap; the blocks missing at the time
still share one read of their span.
Each cell ran from a 90-day block boundary to today, so paging back through
days left a nearly full copy of the two years per boundary in an unweighted
bucket, and a cold day long ago read everything from its window to today.
The history is now cached in 90-day blocks that end before today (the block
holding today ends at today and carries it in its key), a window is put
together from the blocks it touches, and the blocks it misses are read in
one query. A cell holds at most one block of days per type.
Every day view compares its day with the two years before it to find
extremes, so stepping from one day to the next read the same two years
of readings again. The history is now cached per record, zone, source
ladder and readable type set, starting on a 90-day block boundary so
neighbouring days share one cell, and each day takes its own slice cut
at local day keys, which is exactly the window a live read would see.
Measurement writes sweep the cell with the rest of the analytics bucket.
A lookback floor inside the window and a window reaching past today
still read live, and a type the modules switch off is never read.
A pulse day value is a mean over thousands of background samples, and
comparing it over two years scanned every one of them: a recent day on a
dense account took about 300 ms, two thirds of it here. Resting heart rate
stays among the compared vitals.
Replace the day, timeline and life-event stubs with their implementations
(#613) and drop the not-implemented helper, its error code and its OpenAPI
response with the last stub.
loadDay reads one local day for every reader: the readings live inside the
record's own day window (never the UTC rollups), through the canonical-source
engine the mood sheet already uses (resolveDayReadings in linked-context.ts),
with the person's usual range over the 30 days before; the record sections
from their own tables, each in the storage form it speaks (an instant in the
local window, a date string with its own zone, a calendar date). A switched-off
module's section is not read; a section the grant does not cover is named
not_shared and not read.
The day, the day index and the new visit preparation (GET /api/day/notable)
are admitted on the readings and narrowed per section through
actingDomainVisibility, so a scoped grant sees exactly its sections. The
timeline and its readiness stay whole-record reads and narrow their lanes the
same way.
Notable days are deterministic keys: a three-month high or low with history
behind it, a first reading, and in the visit preparation a regular reading
that stopped. The timeline lays out spans and points from the owning tables,
standing items without a date, and series by zoom: months from the rollup
tier inside its five-year window and from one cached live query before it.
The readiness inventory rates each lane with one link per gap.
Life events are created, edited and soft-deleted as MANAGE verbs with audit
rows, encrypted at rest, and join the sharing guard and the handler matrix.
get_day reads a day for the Coach and the MCP endpoint without life events,
notes or document names; its step carries the date it read.
