The recheck and follow-up rules now ride the tool-mode prompt only once
the conversation holds a table, or from the round after the turn produced
its first one. The clarifying-question rules are shorter and English for
every locale, like the other instructions to the model; the German copy
of them and of the recheck rule is gone. A turn without tables sends
about 1 300 characters less on every round.
The golden transcripts change only in the system prompt's hash and
length (4 509 to 3 187 characters; 4 728 to 3 280 for the German turn).
Sealing the practitioner's address left the appointment arm reading the old
readable column, which is now empty, so a booked visit's push lost the address
on booking, rescheduling and restoring a deleted visit.
The reminder no longer keeps its own copy of the address. The reminder tick
resolves it from the owning visit's practitioner when it builds the push and
decrypts it there, so an edit of the address also reaches a nudge that is
already booked. MeasurementReminder.location stays NULL on appointment rows:
booking writes none, a re-anchor clears one an earlier release wrote, and a
backup neither carries nor restores one. A checkup's own free-text location is
unchanged.
Up to three chips, derived on the server from what the turn read: the
other view of a table with a chart, the period before, a year earlier,
a wider window, and a metric a discovered pattern links to. A chip is
offered only when its read was done this turn and the record holds the
metric; the year-ago and wider-window chips also need the record's
first reading to reach back that far. The model may name chips in a
FOLLOWUPS block, but only to reorder ones the rules already allow; every
label is rendered from the catalog.
A tapped chip resolves against the chips stored on the conversation's
latest reply. "As a chart" and "as a table" are answered from the
stored table without a model call or a budget reservation: the rows are
copied unchanged and the message is tagged providerType "reuse". Other
chips run a normal turn with a server-written context line. A chip that
is no longer current falls back to a plain message.
A setting turns the chips off (absent means on).
The line that resolves an answered clarifying question was already
appended to the system prompt on both paths; nothing proved it for the
no-tools (local model) path. Three route-level cases now do: the local
prompt and the tool-mode prompt both carry the server-resolved line, and
a turn without an answer carries neither. Removing the line from the
local prompt fails the first case.
The golden harness gains a coachMessage.findMany mock for this; it
defaults to no rows, so no existing transcript changes and the golden
snapshots are untouched.
The result-table caption test used the regex dotAll flag, which the
TypeScript target rejects (TS1501); it matches across lines with
[\s\S] instead.
get_metric_table reads one metric as days, weeks or months through the
chart reader, cut in the user's zone and collapsed to one source per day,
with null for a period without a reading. The model reads a bounded
summary; the full table rides the turn, encrypted at rest. show_result
shows a table an earlier reply of the same conversation fetched, resolved
only against that conversation's own messages. Workouts, labs, sleep and
adherence results project into tables, earlier tables are named in the
context by metadata alone, and result:rN marks are stripped from the reply.
The evidence disclosure under a Coach answer now carries one muted
line: which sources and windows the turn read, how many readings, and
how they were aggregated ("Blood pressure, last 90 days: 142 readings,
weekly averages · Sleep, last 30 days: no readings in this window").
The server builds it from the recorded steps and tables in the request
locale; it holds catalog strings and counts only, never a reading, and
a source that turned up nothing says so.
The tool-mode prompt gains a recheck rule: when the person questions a
figure, name the source and window, read it again (or reuse the stored
table), and correct the answer if the two differ.
Each tool call now emits a running step as it starts and its final
status as it settles: found with a server-counted number of readings,
empty with the reason, or failed. The no-tools path shows one step for
the record summary. Steps carry catalog labels rendered in the request
language, closed-enum domains and windows, and integers only; a lab
analyte, a value or a model-written argument never reaches one. At most
twelve per turn. They persist on the provenance, so a reload shows the
same list.
The conversation window reaches the step so a call without a window
names the one it actually read. The no-tools transcripts gain the
summary step; a new transcript pins found, empty and failed steps ahead
of the first token.
A reply may end with a ---CLARIFY--- block (kind metric, window or
context, 512-byte cap). The server keeps only metric choices the record
holds, drops the question when fewer than two remain, takes window
choices from the presets, screens the question text like any reply, and
never offers a second question right after one. Choice labels come from
the catalog, never from the model.
An answer arrives as clarification { messageId, choiceId? }; it resolves
against the stored question on the conversation's latest message and
adds one server-written line to the next turn's context. The card sits
above the composer, announces politely and takes no focus.
A reply that is only the block, with no question before it, is now an
empty reply instead of falling back to the unstripped text.
GET /api/insights/chat/{id}/messages/{messageId}/results returns the
tables one assistant message read, narrowed to the conversation's owner
like the conversation read, with a table withheld as module_disabled when
its domain's module is off and as unavailable when it cannot be read. A
data read: no AI capability.
The published document now describes every stream frame as the
CoachStreamEvent union, including the suggestedAction frame it never
named, the new step, result, followUps and clarification frames, their
components, the provenance fields, the followUp and clarification request
fields, and the reuse provider type.
Each later piece of the dialog gets its own module, answering nothing for
now: the step builder, the table projection and chart choice, the result
ref marks, the follow-up derivation, sentinel, resolution and continue
chip, the reuse turn, the clarification parse and answer, the method line,
and the four prompt addenda. The turn pipeline calls them where they
belong, so the frames go out in the documented order (step, token,
provenance, result, cards, clarification, followUps, done) and a blocked
turn drops its tables, chips and clarification. With every piece empty
the stream and the prompt stay byte for byte as before.
The home location of the environment module was rounded to 2 decimals,
about 1 km, which places a home in a neighbourhood rather than the town the
schema comment promised. The weather archive it feeds is gridded at 9 to
25 km, so the extra precision bought nothing.
Every stored coordinate of the module now goes through the same 1-decimal
rounding (about 11 km north-south, 7 km east-west at 50° N): the home, the
travel periods, the geocoder's results, the per-day weather rows, and a
restore of a file written with finer values. Migration 0361 rounds the
existing users, travel periods and per-day rows; running it twice changes
nothing more. The answers keep their shape, plain numbers. The API
descriptions and the schema comment say 1 decimal now.
The route keeps the front door: auth, the coach capability, the body
read and schema, the rate limit, the locale and the inbound refusal
screen. Everything after it moves into one module per step:
conversation, context, chain, budget, model, reply-guards, cards,
provenance, persist, sse, errors and pipeline. The capability re-check
at the egress site stays owned by the route and is handed to the
pipeline, so the capability inventory still reads both calls there.
The stream producer now writes through a TurnEmitter created inside
createSseStream and passed to the model step, which is where live
progress frames will come from. Nothing writes to it early yet.
No behaviour change: the golden transcripts pass byte-identical, the
existing route tests pass unmodified, and every annotate, audit and
error-code name appears as often as before.
Guards follow the code. The fence call-site check reads turn/context.ts,
the German-default locale ban covers every file in turn/, and the
fenced module-graph test now asserts that turn/sse.ts and turn/errors.ts
reach neither the tool registry nor the snapshot builder. That test
named lib/ai/coach/tools.ts, which stopped existing when the registry
became a directory, so its negative check could not fail; it points at
tools/index.ts now, and a new sanity check fails if the tool route can
no longer reach the path it names.
The GPS track of an outdoor workout was stored readable, and its first and
last points are usually the person's front door. The phone number and address
in the address book of doctors and practices were readable too, while the
note beside them was already encrypted.
Migration 0361 adds workout_routes.geometry_encrypted (the geometry loses
its NOT NULL) and practitioners.phone_encrypted / location_encrypted, plus
partial indexes on the backfill's discovery predicates. A track is sealed as
one binary AES-256-GCM value bound to its purpose; the contact fields use the
same Bytes codec as the note. The practitioner's name, practice and specialty
stay readable, because the picker searches and sorts on them.
Every writer stores ciphertext only: workout batch ingest, practitioner
create and edit, and both restore formats. Readers prefer the ciphertext and
fall back to the old column for rows not yet migrated: the workout detail
(map, splits, GPX), the activity insight's climb figure, the practitioner
DTO behind the address book, visits and vaccinations. The wire shape does not
change. An edit's audit row now names a changed phone number or address
without recording either value.
free-text-encryption-backfill covers the three columns in the same pass,
finding a route through its workout. All three are registered for key
rotation (registry, CLI script, and the in-app rotation). A disaster-recovery
backup carries the contact fields as ciphertext only; a portable export
carries them readable. Workout routes are still not part of a backup, as
before. The old columns are marked for removal in a later release.
Drive POST /api/insights/chat through the real SSE stream and the real
reply guards for every branch a turn can take: tool mode with present,
drifted and missing figures, the no-tools path, inbound and replayed
refusals, the budget refusal, each provider failure class, a cancelled
turn, the outbound block, every sentinel in its valid and malformed
forms, learn-link scrubbing, the three no-provider paths, a workout
scope, the post-call defect path, and the refusals that answer before
the stream opens.
Each transcript records the frames the client receives (heartbeat
comments dropped) and the ordered side effects: persisted messages,
budget reserve and reconcile, audit rows, annotate names with their
meta keys, and the provider inputs as prompt fingerprints.
The per-account password limit refused every attempt once ten failures
had landed in fifteen minutes, counted before the password was checked.
Ten guesses from two addresses therefore locked a password-only account,
the app's password sign-in included, and repeating them kept it locked
for as long as anyone cared to.
A place the account has signed in from before is now neither counted nor
held back: a remembered browser, a phone presenting the device id a login
of this account was issued to, or an address a session or device login of
this account came from in the last thirty days. Anywhere else gets five
free failures a day and then a wait that doubles with each failure, from
thirty seconds to at most fifteen minutes, instead of a wall. The per-IP
limit is unchanged, and an unknown identifier is limited the same way on
its hash.
Under an SSO-only policy, a password sign-in to an account other than the
one a pending link names is now refused before the password is checked,
so that exception no longer tells right passwords from wrong ones.
Allowing an AI assistant hands it a standing credential to the record
that outlives the session, the same class of act as minting a token, but
the consent took a live session alone. A stolen session could connect
its own assistant and keep reading after the owner signed everything out.
The consent page now shows the Allow form only when the session signed in
or re-proved within five minutes (with the second factor on an account
that has one). Otherwise it links to a new confirm page that runs the
same re-proof dialog as the rest of the app and returns to the exact
consent request. The allow decision checks again and mints nothing
without it; deny needs no proof. The confirm page only ever returns to
the consent endpoint.
Offering access to the record took a live session alone, and an
invitation outlives the session that sent it: whoever held a stolen
session could invite their own account and keep a way into the record
after the owner signed everything out. POST /api/account/grants now takes
the recent-proof gate at every level (a sign-in or re-proof within five
minutes on the browser, with the second factor on an account that has one;
a step-up elevation on a token, which no shipped client uses here), and
the invite form opens the re-proof dialog and sends again.
Sign out everywhere now withdraws every invitation the account offered
that nobody has accepted. Accepted grants are left standing on purpose:
each is a person the owner chose, often a carer who still needs the
record, and a sign-out button must not quietly cut them off. The response
lists them as grantsKept and the sessions card shows each with a one-click
End access.
GET /api/export with type=all (the default), POST /api/export/health-record
and GET /api/fhir/Patient/$everything hand over the whole record but took a
live session alone, so a stolen browser session could still walk off with
everything the full-backup gate was meant to protect. A browser session now
needs a sign-in or re-proof within five minutes, with the second factor on
an account that has one, and the doctor-report panel opens the re-proof
dialog and retries. When a manager builds the report for a record they
manage, their own session is the one asked.
On a token the shipped app keeps working: health-record and $everything
take the token as before, including a fhir:read token, and the recent-proof
guard names both. GET /api/export?type=all, which no shipped client calls
with a token, wants a step-up elevation there. Single-type exports are
unchanged.
The API reference now also describes the enrollment rule for accounts
with a second factor and the passkey refusal it adds.
A reminder's first-due date could only be sent as a date-time, and the
web form sent the browser's local midnight, so a browser set to a zone
other than the profile's could move the day. The API now also takes a
bare calendar date and stores it as that day's midnight in the user's
zone, and the web form sends the date itself. A date-time still means the
instant it names.
On an account with a second factor, TOTP setup, security-key registration
and passkey registration no longer accept the password, a password re-proof
or a session younger than five minutes. A remembered browser skips the
second factor at sign-in and still creates a fresh session, so the password
alone could add a key that then satisfies every gate the factor protected.
Only a TOTP code, a security key, a passkey or a completed second factor
within five minutes opens enrollment there; the Bearer arm of TOTP setup and
security-key registration asks the same of its elevation. Accounts without
a second factor keep the previous rules.
The refusal names the proofs the account can give, and the enrollment
dialogs offer exactly those. A proof that verifies now gives its attempt
back to the shared re-proof budget, including the current password on a
password change.
A data wipe during the nightly upload could leave the pre-wipe copy in
the bucket: the purge the wipe started removed its request at once, and
the upload still in flight checked that request after finishing and found
nothing. A wipe's request now stays until a nightly run has walked the
account since the wipe. Until then each purge removes only the copies
dated up to the wipe's day, so the copy of what the account holds after
the wipe stays, and the admin card no longer counts the waiting request
as copies still in the bucket.
A re-import that moved a reading to another instant re-folded only the day
it moved to, so the day it left kept the reading in its rollups. And a
write chunk that failed part-way ended the request before the re-fold ran;
a retry then read the landed rows as duplicates and touched nothing, so
those days kept their pre-import rollups for good. The re-fold now covers
the old instant of a moved row and runs whether or not the writes finish.
Making `=true` grant nothing would stop a single-user self-host's local
model on a patch update. It is deprecated for one release cycle instead,
in a narrowed and safe form: it still grants a private host, but only to
the operator's own configurations (the instance-wide admin provider and
AI settings saved on an admin account), and only through the pinned
operator-approved dispatcher, so redirects stay forbidden and metadata,
link-local and unspecified addresses stay refused. A non-admin account's
own base URL needs an exact origin in AI_PRIVATE_ORIGINS.
Provider resolution passes the owning account's role to the client
(`operatorTrusted`); the save route and the connection test apply the
same rule to the account being configured. The boot summary now says the
setting is deprecated and names the replacement, and the admin AI
settings page shows the exact AI_PRIVATE_ORIGINS line for the private
origins saved on the instance (every account's Local and gateway URL and
the admin base URL, scheme, host and port only), so the operator can copy
it and drop the old setting.
The admin wipe of every account is the operator clearing their own host,
and the bucket's copies are the documented way back from a wipe pressed
by mistake, so it writes no off-host deletion request. Deleting an
account, deleting a managed profile and "Delete all data" still do.
The backup runbook no longer says the worker never deletes an object: it
lists the grant the worker needs (DeleteObject included), when objects
are deleted, the version-4 envelope, the lifecycle check and how to
rotate the off-host key. The rotation runbook no longer says backups are
covered: rotation reaches a backup's envelope, not the content a restore
writes back, and a retired key stays needed until no backup lists it.
The privacy notice beside account deletion says the same about off-host
copies.
A failed import records its failure in a plain try block, and the
extraction test that inflates past the 64 MiB floor gets the time it
needs on a loaded runner.
The list of provider tags that send data out through a credential the
operator holds (admin-openai, admin-codex) existed four times: in the
consent gate, in the capability resolver, in the shared-provider health
read and in the admin provider-health ordering. A tag added to one and not
the others would be consented for in one place and not the other. The list
and the local-provider test now live in src/lib/ai/provider-egress.ts and
every reader imports them.
The guard meant to keep one copy matched a variable name, so the copy in
the resolver, under another name, never tripped it. It now matches the
list itself in either order and names the one file allowed to hold it.
Off-host objects are now written as envelope version 4: the header names
the off-host key by fingerprint, and the object's key in the bucket
(<date>/user-<id>.json.enc) is authenticated as GCM associated data, so
a copy moved to another account or another night no longer opens.
Objects of versions 1 to 3 still read. BACKUP_ENCRYPTION_PREVIOUS_KEYS
(comma-separated, on the compose whitelist and in the env manifest)
keeps retired off-host keys readable, which is the rotation path the
off-host key did not have.
The admin backup upload counted the bytes that arrived and none after
the gunzip, so a small gzip could expand without limit into the JSON
scanner and take the app down. The inflated bytes are now held to 100
times the compressed bytes read (at least 256 MB, at most 4 GB) and a
file past that is refused with 413 before anything is stored.
The extractor held the inflated export.xml to a flat 8 GiB whatever the
member occupied, and the header ratio check reads sizes the archive
writes itself: a member declaring an honest ratio could inflate at
1000:1, so an 8 MB upload could fill the temp directory. The streamed
byte count is now held to 200 times the member's compressed size on
disk (never less than 64 MiB, never more than 8 GiB), and a stored
member may not grow at all.
An account may have one Apple Health import queued or running. A
second upload with different bytes is refused with 409
import.apple_health.busy and the running job's id; the check and the
new row are one transaction under an advisory lock.
The staged upload is the person's export in plain text. It is now
removed on every exit that leaves no worker to read it: a refused or
broken multipart body, no worker running, a queue that takes no job
(the row is failed as well), the admin route's missing or unknown
target account, and an account deleted before the worker reached it.
The worker removes the files before recording a failure, so a row that
went with a deleted account no longer strands them. The 15-minute
import reconcile pass also sweeps staged files older than the longest
an import may run.
Password sign-in was limited per client address only, so guesses spread
over many addresses reached one account without end. Each account now has
its own ceiling of ten failed attempts in fifteen minutes, whichever
addresses they come from. The attempt is counted before the password is
hashed and given back when the password is right, so the owner signing in
does not use it up. An identifier that matches no account is counted under
its hash with the same ceiling, so the refusal does not reveal whether the
account exists. Passkey and single sign-on remain open while the ceiling
is reached.
"Sign out everywhere" ended web sessions and device logins but left every
credential that works without signing in: a connected AI assistant kept its
OAuth connection and minted the next access token from it, a connector or
ingest token kept working, and a clinician share link kept opening the
record. A password change revoked the tokens but not the assistant's
connection or the share links. Anything a stolen session had minted
outlived the remedy.
- Sign out everywhere now ends every other sign-in, every AI-assistant
connection, every programmatic token except the caller's own, and every
clinician share link. Share links are revoked by default; the web offers
a checkbox to keep them (keepShareLinks=1), and a client that sends
nothing, such as the shipped app, gets the safe default.
- A password change and an admin password reset also end AI-assistant
connections, share links and step-up elevations.
- Turning on the first second factor (TOTP or a security key) ends every
other sign-in, as a password change does. Adding a further factor does
not.
destroyOtherSessions takes an explicit reach ("sign-ins" or "everything")
so each caller says how far it goes.
Re-uploading a large export with an externalId column ran one
updateMany per row inside a single interactive transaction; on a
9 000-row file that outlived Prisma's 5 s timeout and the request ended
in a 500.
A re-imported externalId row whose stored value, unit, instant, glucose
context and note already match the line is now a duplicate: not written,
reported as skipped / duplicate. Changed rows still update, a tombstoned
one is still resurrected. The existence probes run per measurement type
in chunks of 1 000 keys, and the writes commit in chunks of 200 (creates
via createManyAndReturn, updates as one batch transaction per chunk)
instead of one transaction around the whole file. A failure part-way
leaves earlier chunks written, and re-uploading the same file completes
the rest.
The OpenAPI description now says what a re-upload does, including the
natural-key dedup for rows without an externalId, which it used to call
a duplicate.
Deleting an account, deleting a managed profile, "Delete all data" and the
admin wipe now write an off-host deletion request in the same transaction
as the deletion. A new job (offhost-backup-purge, kicked straight away and
run nightly as a backstop) lists the bucket once, deletes every
<date>/user-<id>.json.enc object of each pending account and removes the
request only when nothing of the account is left. A refused delete keeps
the request with the bucket's answer and is retried; the off-host card
shows how many deletions are outstanding and why. A copy the nightly run
was writing while the account was deleted is taken back after the upload.
The off-host card also reads the bucket's lifecycle rule and says plainly
when there is none (every nightly copy kept forever) or when the
credential may not read it.
Every stored backup now records the key ids its content was written
under, and every off-host upload records the same per key. The admin
encryption view lists, per key, the stored copies that need it with the
oldest date, and when the last off-host copy needing it expires. The
"safe to drop" badge now requires that no backup still needs a retired
key, instead of only that every row was rotated.
Migration 0358 adds data_backups.inner_key_ids, the key-use table and the
deletion requests.
Exporting the whole record, making a clinician share link, minting a token,
and the admin backup download, upload and restore, data wipe and password
reset ran on a live session alone. The plaintext full backup did, while the
encrypted one beside it asked for a second factor. Whoever held a stolen
session could take the record, or leave behind a credential that outlives
the session.
These now go through one gate, requireRecentProof (assertRecentCookieProof
for the routes that resolve their caller themselves). A browser session
passes after a sign-in or re-proof within five minutes: a second factor on
an account that has one, otherwise the password or a passkey. The refusal is
401 auth.reproof.required with meta.methods, and the web opens the re-proof
dialog, posts the proof to the new POST /api/auth/reproof and retries. A
password proof stamps the new Session.reproofAt (migration 0359), never
mfaVerifiedAt, so it cannot stand in for a second factor anywhere.
On Bearer, the full backup asks for an X-Step-Up elevation; the encrypted
export asks for a second-factor elevation on an account that has one. Share
links and connector tokens keep taking the token alone, because the shipped
app calls them without an elevation and reads a 401 there as a dead
session; the guard test names them.
Key rotation keeps its stricter second-factor gate.
ALLOW_LOCAL_AI_PRIVATE_HOSTS=true let any user of the instance point the
Local provider or the OpenAI-compatible gateway at any private address
the server could reach, the metadata range included, and a granted host
was dialled with no connect-time pin at all.
AI_PRIVATE_ORIGINS grants a private AI endpoint with the exact-origin
grammar NOTIFICATION_PRIVATE_ORIGINS and NIGHTSCOUT_PRIVATE_ORIGINS use.
A granted call goes through the pinned operator-approved dispatcher:
redirects forbidden, and metadata, link-local and unspecified answers
dropped at dial time even for a granted name. Everything else stays on
the public pin. The Local client (buffered and streaming) and the
gateway and admin-key tags of the OpenAI client all take their policy
from one function.
The host-list form of ALLOW_LOCAL_AI_PRIVATE_HOSTS keeps working with the
same pinning; a never-grantable literal or a host:port entry is refused
with a one-time warning. Its "true" form grants nothing any more and is
reported in the boot readiness summary with the replacement.
A failed lab-report scan no longer puts the endpoint's response body into
the wide event; status and model stay. The response to the caller never
carried it.
The title of a Coach conversation is the first 80 characters of the
opening message, and the note on a custom-metric reading is free text;
both were stored readable while every other note was encrypted.
Migration 0357 adds coach_conversations.title_encrypted and
custom_metric_entries.note_encrypted (the title loses its NOT NULL) plus
partial indexes on the backfill's discovery predicate. Every writer now
stores ciphertext only: conversation create, proactive nudge, reminder
surfacing, rename, entry create and edit, and both restore formats.
Readers prefer the ciphertext and fall back to the old column for rows
not yet migrated; a ciphertext that does not open throws instead of
falling back. The history title search decrypts in memory, since SQL can
no longer match the title.
free-text-encryption-backfill is a boot-time, idempotent pg-boss job
(staggered past the startup storm, daily discovery tick) that seals each
remaining readable value and nulls it in one transaction per row. A pass
that sees a row twice stops with an error instead of looping.
Both columns are registered for key rotation (registry, CLI script, and
the in-app rotation that walks the registry). A disaster-recovery backup
carries ciphertext only, sealing a not-yet-migrated row on the way out;
a portable export carries readable text. The old columns are marked for
removal in a later release.
A backup carries every encrypted column as the stored ciphertext, and a
restore writes it back verbatim. Key rotation re-seals the stored copy's
envelope but cannot reach inside it, so a copy taken before a rotation
still needs the retired key. Without it the restore went through and
left rows no reader can open.
The restore, the restore preview, the admin upload and the monthly
restore drill now collect the key ids of every inner ciphertext value,
hold them against ENCRYPTION_KEYS and decrypt one value per key. A
missing key, or an id configured with different key material, is
refused before anything is deleted, with the key id named. The restore
status and the preview say which key to put back.
The restore also checks, inside its transaction, that it added no
reference from the account's rows to rows another account owns. The
check is derived from the schema's foreign keys rather than written per
section, so the tag and category upserts keyed on a global key are
covered along with every link table. The illness parent update is
scoped to the owner as well.
The off-host listing now follows every page: the first page held only
the oldest dates, so the drill could read an old object and report the
chain as stale.
