Fetch the Open-Meteo air-quality feed (CAMS, domains=auto) with the weather:
17 hourly variables folded into local days by fixed rules (means and maxima
only with 18 of 24 hours, ozone as the highest 8-hour running mean, UV only
with the midday hours), a value the feed did not cover stored as null, never
as zero. Requests are cut into 90-day chunks, newest first, and chunks before
mid 2022 ask for the eight pollutant and index variables only. An air-quality
failure never costs the weather row; the day stays unfetched and the nightly
gap fill (up to 90 days per account, newest first) asks for it again.
Every Open-Meteo request asks an instance-wide budget kept in Postgres first
(500 a minute, 4000 an hour, 8000 a day, weighted by the hosted pricing
rule). A refused request is not sent and the run ends as done with
budget_blocked. OPENMETEO_AIR_QUALITY_URL and ENVIRONMENT_AIR_QUALITY_DISABLED
are honoured; the account switch lives on PATCH /api/environment/preferences.
The home, each dated location period and each stored day keep their coarse
location sealed as one value under healthlog/environment-location/v1. The
writers write the sealed value only, the readers open it and fall back to the
readable columns for rows the free-text encryption backfill has not reached,
and the backfill now seals all three and clears the readable columns. The
backup carries the location readable in a portable file and sealed in a
disaster-recovery file; a restore seals either under the receiving key.
Three correlation channels join the environment family (PM2.5, the ozone
8-hour high, the day's highest pollen count), read through the averaged
same-day window and left empty while air quality is off. The Coach and MCP
gain get_environment: module-gated, clamped to the lookback limit, no
coordinate or place name anywhere, with provenance and the attribution
lines. The settings section gets the switch, the coverage and the newest
day's values; the dashboard shows a quiet chip on a day with high pollen,
a warm night or very poor air. Copernicus and Open-Meteo are credited next
to the values.
Two daily series that both follow the season (temperature and blood
pressure, daylight and sleep) correlated strongly with nothing between
them. In a seeded simulation of such a pair the engine surfaced a
finding in 58 % of 400-day runs and 30 % of 180-day runs, and a real
next-day effect under the season came back with the wrong sign.
Every daily pair now goes through seasonallyAdjustedPearson: a linear
trend and one annual harmonic are removed from both series (trend only
under 120 paired days), the residuals are correlated, and the p-value
uses the Pyper-Peterman effective sample size. Shrinkage and the
phrasing tier read the effective size too. BH-FDR and the effect floor
are unchanged. Pairs too short to fit the basis are not tested.
The weather channels are tested once over the mean of the day before
and the day itself against the same day's outcome (lagDays 0), which
pairs the overnight low with the night it shaped now that sleep is
keyed on the wake day. Discovered pairs carry an additive nEff, the
same-day templates are wired, and the matrix skips the weather read
when the environment module is off.
scripts/compare-correlation-findings.ts counts findings per account
before and after, read-only, for the release-candidate dry run.
Land every file the v1.42 work shares before any of it is built, so the
parts built side by side never edit the same file.
Schema and migrations 0379-0386: the HEALTH_CONNECT measurement source,
ImportJob.kind, the air-quality columns and the per-user switch on the
environment tables, sealed environment locations with nullable plaintext,
managed-profile handover links, the per-type HealthKit arrival ledger, lab
unit-conversion provenance, and user-defined vaccines. Every new column is
annotated for the column-reader sweep.
HEALTH_CONNECT reaches every exhaustive list: the source labels, the
read enum (not the write allowlist), the source-priority ladder cap, now
the number of sources rather than a fixed eight, and the write-path smoke
test. RMSSD gets its own priority class and a 300 ms ceiling. The batch
syncTrigger gains `manual`, with its label on the Apple Health card.
Queues for the Health Connect import, the compaction-tombstone purge and
the measurement-table maintenance are registered with stub handlers;
host-metric sampling moves to every five minutes. Environment and work_mem
variables reach the compose whitelist, the production example and the
manifest. The proxy admits the handover link and redirects it at the edge,
and the Health Connect upload bypasses the proxy body limit.
The new routes answer 501 behind their final authentication and are
published in the contract; backup, wipe and key rotation classify the new
models and columns; the seven message bundles carry the base copy. Guards
that list release-pending keys and columns fail once an entry is wired, so
those lists empty themselves before the tag.
Also re-anchor a login-throttle fixture to the wall clock, where its
expiry is compared, and re-base the aggregate bundle cap on a measured
12 KB of new locale strings.
list_metrics declares availability, the Coach-backed reads declare
searchedWindow and available, and get_intraday_pulse declares min and
max per bucket. An integration test validates every tool's real output
against its advertised schema under a strict 2020-12 validator.
The metric-status discovery rows and the search clinical-signal probe
filter deletedAt, guarded for every measurement read in the MCP and
Coach tool trees.
Own-plan turns get 165k tokens, 200 s and 16 rounds, operator turns 55k,
120 s and 8; the final-answer reserve, the concurrent-turn slot and the
step cap move with them.
Codex requests carry a per-conversation prompt_cache_key and a stable
session id, api.openai.com gets the same key, Anthropic usage counts
cache reads and writes in the gross, and local servers report cached
prompt tokens, so the turn budget discounts cached input on every
provider.
While a turn runs the Coach now shows a single row: a brain icon, the
current step in the answer's text size with a shimmer passing through it
and fading dots, and a chevron once there are steps to open. There is no
running clock any more, and the interim table preview with its sparkline
no longer renders under the row; interim tables stay in state until the
answer's own results show them.
When the answer is done the row reads "Thought process · N steps" with
proper plurals, and "Answer needed" while a clarifying question waits.
It never opens by itself, and a row opened during the run closes when
the turn ends. Opened, the steps form a vertical list with an icon per
kind of work on a thin connector line, and a reasoning round shows its
summary under its title.
The shimmer and the dots are a `text-shimmer` utility and a reusable
WaitingText component, both still under reduced motion.
The demo's write block now carries `meta.errorCode: "demo.readOnly"`,
listed in the error-code catalogue, and the Coach answers it with an
honest line instead of the provider-outage copy.
Removes the interim preview component, the elapsed-seconds and summary
helpers, and their message keys in all seven locales.
The Coach loop's final round sent toolChoice "none" without the tool
definitions. With tool_use/tool_result blocks in the history Anthropic
refuses such a request (400), and OpenAI Chat Completions refuses
tool_choice without tools, so every budget, time, cap and no-progress stop
ended in an error on those wires. The final round now carries the tools
with toolChoice "none", which every wire accepts, thinking included.
Codex kept reasoning items as provider state even when the request asked
for no encrypted reasoning; replaying such an item under store:false is a
400. Items are kept only when the request included
reasoning.encrypted_content and the item carries it.
The reasoning dialect cache learned from any 4xx that mentioned
reasoning or thinking (auth, rate limits, model names such as
deepseek-reasoner) and from replay errors, and kept the downgrade for the
life of the process. Learning now requires an HTTP 400 that refuses a
sent parameter, ignores replay errors and the model name, and a learned
downgrade expires after an hour.
remember_fact and propose_plan wrote their rows during the tool round. An
answer that was then blocked, failed or abandoned left the fact in memory
without its note and Undo, and left the plan listed, activatable and fed
into later turns and the briefing. Both are now staged under an id minted
up front and written in the transaction that stores the assistant message,
only when its provenance carries them. A background proposal counts as
offered only once an answer carrying it is stored.
Plan text is model text: ifCue, thenAction and target pass the outbound
dose and risk screen in the person's locale, with their scheduled doses and
medication names, and the injection screen; a trip declines as "unsafe".
The trail route serves recalled facts and the proposal's fact to the owner
whatever the AI capability (only the model-written entries are gated), and
withholds medication facts while the medications module is off.
Accepting a fact proposal is decided under a per-message advisory lock, so
concurrent taps write one fact. Editing a fact re-reads its wording: text
naming a medication moves to "medication", other health wording moves a
non-health fact to "condition", and a health fact the person edited counts
as confirmed.
The dose-change class demanded a dosage-form noun next to every skip, stop
or extra imperative, and a drug name never counted. "Skip the amlodipine",
"then take an extra ramipril", "take one more tablet of ramipril", "Nimm
abends eine Tablette mehr", "Lass das Ramipril morgen weg" and "Stop your
blood thinner before the run" all passed.
A medication noun is now a dosage-form word, a drug-class word per locale
(blood thinner, Blutverdünner, anticoagulant, statin, insulin, ...), a
common generic-name stem (-pril, -sartan, -olol, -dipine, -formin, ...),
or one of the person's own medication names. The Coach loads the names
with the turn context and passes them to the reply screen and the trail
screen; a scheduled brand name is only known that way.
Add the extra / another / one more shape in en, de, fr, es, it, pl and ko,
spelled-out counts as a dose target, and stop / leave out / go without a
named medication. The number-free shapes use a two-word slot that a
preposition ends, so "take an extra minute to log your medication" and
"stop worrying about your medication" pass. A sentence that only names a
drug, a schedule description, a past change from the log, a negated
warning and a referral ("ask your doctor whether you should stop ...")
still pass.
The signals of the day held today's newest single reading against the
7- and 30-day mean of every reading. For glucose, whose level climbs
with each meal, a fasting morning read as low against an all-day mean
and fed that into the briefing and status prompts. A type in
SAME_HOURS_TYPES now compares today's mean so far with the earlier
days cut at the local time of today's latest reading, the basis the
coincident-deviation flag and the metric strip already use. Below a
week of like-for-like days there is no signal. The signal carries
basis "sameHours" and both briefing prompts say what it means. Other
metrics keep the reading-against-window comparison.
The usual-range strip called the newest reading today's on every
metric page, even when it was days old. CoachReadBaseline now carries
latestDate (the reading's day in the account's zone) and latestIsToday
(isFromToday), on the REST response and the get_metric_baseline MCP
output. The strip names the date when the reading is not from today,
in all seven locales.
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 usual-range strip on a metric page placed the latest single reading
against a band built from whole-day means. For glucose the day mean climbs
with every meal, so at nine in the morning a fasting reading sat under a
band of whole days and the strip said "below your range" on an ordinary
morning; the MCP baseline read reported the same.
Glucose is now placed by its day mean. A day still in progress, in the
reader's own zone, is held against the earlier days cut at the local time
of today's latest reading, the comparison the health status already makes;
with fewer than seven earlier days that have readings in those hours there
is no verdict. The baseline carries `basis: "sameHours"` on the coach-read
route and the MCP read, and the strip names the range as the one for this
time of day, in all seven locales. Other metrics keep their placement.
"Increase your metformin to 2000 mg daily" passed the outbound dose
screen. The English change pattern accepted only "it" or "your dose"
between the verb and "to", so a drug name in that slot walked past it,
and no pattern covered an imperative to take a stated amount, a count
unit (tablets, capsules, puffs), or an imperative to skip or stop a
medication. Each locale bank had the same narrow object slot.
Add a per-locale dose-change class (en, de, fr, es, it, pl, ko) with
three shapes: an imperative or infinitive change verb with up to four
words of object and a target dose; an imperative to take or inject a
stated amount; and an imperative to halve, double, skip, pause or stop
a medication. Negated imperatives, past-tense log restatements,
present-tense descriptions ("you take 1000 mg"), clinician referrals
without a target, and nutrition advice (sodium, water, steps) still pass.
A unit now ends on an explicit lookahead instead of \b, so a lab
concentration ("under 140 mg/dL") no longer trips the dose bank while a
rate ("2000 mg/day") still does. "as usual" and "wie gewohnt" join the
continuation anchors, still gated on the user's schedule.
The chat route hands the turn the level resolveCoachTurnReasoningLevel
returns: the stored Coach preference, absent read as medium, after the
operator's switch and cap. The turn still applies the operator-paid
ceiling once its chain is known. The controls loader no longer throws
when the request cache cannot serve it; it fails closed to off. The
admin guard pins the route to the resolver.
Build the memory block for the providers the turn sends to, send it on
both paths, keep the facts it recalled in the owner's trail, and offer a
health fact the background found as the answer's one note. Every turn
enqueues the memory refresh; the job's debounce and singleton key decide
when it runs. A remembered fact points back to the stored user message.
The briefing prompt carries the server-computed progress line of up to
two active Coach plans, fenced as data because it quotes the person's
own goal words. The model may mention one and may not invent one; the
figures in the lines are admitted by the grounding gate like any other
figure the server handed over. The lines join the snapshot fingerprint
only when there is one, so an account without an active plan keeps its
stored fingerprint, and a failure to build them drops the lines, never
the briefing.
runStatusCompletion and runBriefingCompletion take an optional
reasoningJob. Only a named job carries reasoning, resolved against the
operator's switch and cap and the payer; a call without one, which is
every status card, batch note, derived score and workout line, sends
exactly what it sent before. Thinking is reserved on the day's ledger
with the answer budget, and a reasoning status call falls back to a
90 s ceiling instead of 60 s.
The briefing reasons on its generation and phrasing re-roll, the weekly
and monthly narratives on their first pass; the JSON and grounding
repairs do not. An inventory test freezes which files may name a job.
GET /api/auth/me gains coachReasoning: the level a turn runs at, the
person's own pick, the highest level the settings may offer, whether
reasoning can run at all, whether the lowest option is a real off, and
the layer that decided. Resolved on the server so the web settings and
the native client read the same answer.
The web reads it through useCoachReasoning. The Coach preferences route
names the stored level on its wide event, and a unit test round-trips
the level through the account-settings backup section.
Add resolveReasoning, the one decision for how hard a call may think:
the operator's switch, then the provider's ability, then the requested
level (the person's Coach preference, or a background job's own level),
then the operator's cap, then a medium ceiling when the operator pays.
The answer names the layer that decided it.
loadReasoningControls reads the two app_settings columns, memoised per
request, read afresh in background runs, and fails closed to "off".
loadCoachReasoningState resolves the published Coach state from the
memoised provider presence; resolveJobReasoning resolves one background
call and never fails it.
A guard proves the switch and the cap over the whole input space and
requires every call that carries reasoning to take it from the
resolver.
Unit tests for the turn budget and the no-progress brake, the budgeted
loop (every stop reason, the round-by-round ledger, repeated calls,
questions, comparisons, reasoning and provider state), the trail recorder
and its screen, clarifications through the tool and the brake, the
comparison table and chart, the trail column and its owner-only read, the
reply frames, and the turn's frames end to end through the route. An
integration test proves the trail against a real database. Eval
scenarios cover a multi-round why question, a period comparison with its
chart, a question asked through the tool, and keep the charts the
existing table scenarios already showed.
Take the effective reasoning level from the route rather than resolving
it in the turn; the turn only caps it when the operator pays.
Give the Coach one statement of how an answer is shaped, in the German and
English bodies and on every other locale: the first sentence answers, one
carrying number with its unit and window, the person's own baseline, an
assumption in one line, at most one next step and no habitual closing
question, 40 to 120 words, and a closed list of filler it never writes.
- Brief is 30 to 70 words in one paragraph, detailed up to 220 in three.
- Motivational-interviewing moves only when the person opens a change topic,
at most one, never as a closing question; the confidence ruler only on an
explicit plan request.
- The few-shot examples are rewritten to model the voice.
- Result tables: show the numbers whenever they carry the answer and span
more than one value, a table for exact values or up to twelve like rows,
one figure alone only for a moment.
- Follow-up chips are the answer's only "what next".
- A voice grader for the eval (length, filler, emoji, next steps, closing
question, warm-up opening) plugs into the golden set as criteria; five
voice cases in German and English.
- A guard holds both prompt bodies to the rules and every example answer to
the grader, each check broken once on purpose.
What a person told the Coach never reached a tool-mode turn: facts and plans
rode the snapshot's memory block, which tool mode does not send, and the
extraction ran only past twenty turns and failed to parse on every
non-Codex chain, because the status chain runs in JSON-object mode while the
prompt asked for a bare array.
- Memory block: WHAT YOU KNOW ABOUT THIS PERSON, built per turn behind the
wire egress check (nothing is read on a refusal), fenced as data, at most
1,500 characters, never trimmed before the inventory. Confirmed facts
first, then the newest; active plans with a server-computed progress line;
reminders the person asked for. Medication facts stay out while the
medications module is off. Building it stamps last_used_at without moving
updated_at. buildCoachToolRequest and buildCoachProviderPrompts take it as
an optional memoryBlock; the snapshot memory keeps only the narrative and
trend recall.
- remember_fact: preferences, goals and context are saved at once
(source coach, source_message_id set); anything that names a condition,
limitation or medication, by category or by wording, is only proposed.
A fact must come from the person's current message; one note per answer.
- The person's answer reads the proposed fact from the encrypted trail on
the assistant message, never from the request.
- propose_plan writes a proposed plan; the tap activates it with its review
window counted from the tap. One per answer, three open at most.
- Progress: one sentence per active plan from the person's own day series
and units, also offered to the briefing (two lines at most, behind the
briefing capability). The plan review and the progress line read a step
plan as daily totals instead of per-sample means.
- Background extraction asks for {"facts":[]} / {"plans":[]} and reads
either shape, runs once a conversation has been quiet for 30 minutes, and
stores health facts as proposals offered once at the next turn.
- Unanswered plan and fact proposals lapse after 14 days in the reminder
sweep.
- Memory list API: POST saves one of the caller's own messages (the
remember button), PATCH edits a fact's wording, GET reports source, origin
and last use and never lists a waiting proposal.
- A structural guard keeps the egress check ahead of every read and the
callers of both builders to the turn and the briefing.
providerState may be read only in the clients, the contract and the Coach tool loop, never on a line that logs, annotates or persists, and has no schema column.
The mock reports a fixed summary, title and provider state for calls that ask for reasoning. The runner passes reasoning and onReasoning to every candidate unchanged and adds the reasoning token and summary counts to the wide event, never the text or the state.
OpenAI sends reasoning_effort for reasoning models on rounds without tools, off mapped to each family's lowest value. Gateways send reasoning_effort, OpenRouter its reasoning object, and the reasoning details or thinking blocks a gateway returns go back on the next round's assistant message. Local servers send reasoning_effort and read reasoning_content, reasoning and a leading think block, live on the stream without letting it reach the answer.
The thinking budget rides on top of the answer budget where reasoning counts against it. A refused reasoning field is retried once without it and remembered per endpoint and model, before the JSON dialect check. A call's own level wins over the stored chain setting, which still applies when the call has none.
Up to 4.5 a thinking budget (with the interleaved-thinking header on tool rounds), from 4.6 adaptive thinking with an effort and summarized display. From the 5 generation thinking cannot be switched off, so off becomes the lowest effort. Temperature is never sent from 4.7 on, nor with thinking, which also removes a 400 on the newer model presets.
Thinking blocks travel to the next round unchanged, signature included; a tool round another provider started runs without thinking. Every text block is joined instead of only the first. The JSON instruction goes only to callers that ask for JSON. Unknown model names learn the dialect and the sampling rule from a refusal.
A call that carries a reasoning level sends reasoning {effort, summary} with include [reasoning.encrypted_content]; off is effort none. Summary titles are reported as soon as the bold first line closes, the text when the part is done. Reasoning items come back as provider state and are re-inserted before the next round's message and calls, only for the slug that made them.
A 400 that names a reasoning parameter is answered with the lesser request the backend lists (no summary, the nearest supported effort, no reasoning), remembered per slug. Calls without a level keep reasoning null and include [].
reasoningSupport() reads what each provider can do with reasoning from the provider type and model name: effort, summaries, live summaries, state that must travel between tool rounds, and whether off is a real off. Unknown names are treated optimistically.
The dialect cache records what an endpoint refused (keyed by provider, endpoint and model) so a client retries with the lesser request once and never pays the refused round-trip again. Downgrades are marked on the wide event with meta keys only.
Replace the fixed three tool rounds with a budget fixed by who pays:
120k tokens, 150 s and 12 rounds on the person's own plan, key or local
model, 40k, 90 s and 6 rounds when the operator pays. Cached input counts
at a tenth. The final answer is reserved from the start, so a turn whose
budget, clock or round cap runs out answers from what it read. A
no-progress brake stops a turn that repeats calls or reads nothing new,
and a repeated call is never run again.
The day's ledger is booked round by round: round one and the final
reserve when the turn starts, each further round right before it runs,
every round settled as it returns, the unused reserve given back at the
end. A round the daily ceiling refuses ends the turn with an answer.
Every phase goes out live as an activity frame (thinking, fetching,
summarising, asking, remembering, planning, the stop, the answer), with
screened reasoning titles and summaries; the structure rides the
provenance and the text is sealed in trail_encrypted, served by
GET /api/insights/chat/{id}/messages/{messageId}/trail. Tables go out as
interim results as soon as they are read.
Add ask_clarification with a server brake, remember_fact and
propose_plan over the memory contract, model-free decision turns,
compare_series with the compare chart, eight tables per message,
assumptions with change-assumption chips, a reasoning level per turn and
at most two concurrent turns per person.
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.
With signals of the day resting on today's readings only, the briefing
had to be written after those readings, and it was only written at the
04:30 Berlin warm, the post-sleep morning refresh, or a page open on a
day-old cache. A morning blood pressure or weigh-in never became a
signal, and since an earlier day's briefing is no longer served, a
reader in Los Angeles or Seoul had none for most of the day: the Berlin
warm lands the previous evening there, or at noon.
The snapshot read every surface goes through (dashboard, iOS, digest,
morning push) now asks for a briefing for today at two moments: the
first read of the reader's local day with no briefing written today,
and the first read after a signal metric's first reading of the day
that the briefing has not read. Each reason is claimed once per user
per local day in a Postgres bucket and remembered in-process, so later
reads cost no query; no write path needs a hook.
A claim enqueues one today warm: immediately for a new day, after a
five-minute window for readings, so a burst (weigh-in, then blood
pressure) folds into one job. The warm writes the comprehensive
briefing only, past the one-hour freshness gate but under the failure
backoff, the daily forced-warm cap (two per 24 h) and the content-hash
gate.
Worst case per user per local day: one enqueue per reason, at most
eight (the day plus seven signal reading types, measured over a day of
reads every two minutes); at most two forced comprehensive attempts
under the existing cap, each at most three completions (the answer, a
JSON retry, a grounding retry), so six provider calls at the ceiling.
A warm whose data has not changed costs at most the existing
once-a-day paragraph re-roll, inside the same cap.
The SDK renders every tool's Zod shape with a fixed draft-07 target and
stamps "$schema": "http://json-schema.org/draft-07/schema#" on each
inputSchema and outputSchema. Clients that validate with a 2020-12-only
validator refuse that dialect when the tool list arrives, so every tool
was unusable there (#1170).
Wrap the tools/list handler once, after the last tool is registered, and
re-render each advertised schema from the same Zod shape with the
draft-2020-12 target, without a $schema key. A schema with no $schema is
2020-12 under the MCP spec and still compiles in a draft-07 client. All
other fields of a tool entry pass through unchanged, and the SDK keeps
validating structuredContent against the Zod shape, so tool results are
unaffected. For the current surface the 54 rendered schemas differ from
the previous ones only by the dropped key.
The new guard reads tools/list through a real client for a write-scoped
session, rejects any draft-07 marker or construct, and compiles every
schema with Ajv's 2020-12 build (ajv added as a dev dependency at the
version the SDK already resolves).
The summary of a condensed block was taken over the block's mix of daily
values and weekly means: over a year the newest fourteen days weighed as
much as fourteen weeks, min and max were extremes of means, and change was
one day minus a weekly mean.
Each series block now hands the budget pass its daily values over the
whole read, computed only when the block is condensed. The summary states
the first and last day, the lowest and highest day, the mean of the days,
and the change from the first calendar week to the latest one. A block
without daily values gets no summary rather than one of what is left. The
coverage note says how the summary is taken.
Only the digest applied briefingForToday. The dashboard snapshot (the
web dashboard, its server prefetch and the iOS cold-launch read) and
the /insights advisor payload still served an earlier day's text and
the raw model deltas ("+33.72 bpm").
The snapshot read now resolves the briefing after the cache, beside
the capability decision, from the payload's generation moment and the
snapshot's own newest reading per type; a withheld briefing reads
"preparing", never "ready" with nothing in it. The digest takes the
resolved briefing from that read on its own clock instead of resolving
again. The advisor route resolves dailyBriefing on every branch it
returns, reading the newest reading per signal type in one grouped
query only when a reading-backed signal is present; text generated on
an earlier day no longer counts as fresh on the read GET (so the warm
is enqueued) and no longer short-circuits a provider-backed POST.
The OpenAPI descriptions of both advisor responses say so.
The check that keeps an earlier day's briefing off the Today surfaces
read the cache row's insightsCachedAt. Every warm moves that column,
including the unchanged-hash short-circuit that keeps yesterday's text
and only refreshes the stamp, so text written the day before passed as
today's after the nightly warm.
The cached payload now carries briefingGeneratedAt, written only where
new text is written: a full generation in the warm and in the
on-demand route, and the daily paragraph re-roll. The stamp refresh
leaves it untouched. briefingForToday reads that moment, and a payload
without it counts as not from today, so the hero falls back to its own
lead until the next generation.
