A background AI run's deadline is armed in model time plus a fixed margin.
Time spent waiting in the document reader's queue, and the read itself, came
out of that margin, so a person's lab scan or document read could be timed
out by the reaper because other work held the reader. When the reader grants
the slot it now moves the run's deadline by the wait plus the most the read
may take, and gives back the unused part when the read ends, never past the
job's own expiry and only while the run is running. The interactive queue
wait stays within the margin, which covers the run until the slot is
granted.
The guard asked whether a file that reads the lab table mentions the gate
anywhere, so one ungated read in a file with a gated one passed, and
whenModuleOn for any module counted as the labs gate. It now walks the syntax
tree: each read must sit in a function that asks the labs module, or in a
private helper whose every caller in the file does, or be listed by file and
function with its reason. whenModuleOn counts only with "labs".
DEPLOY_WEBHOOK_REQUIRE_TIMESTAMP had been changed to mean signed requests
only, so an operator who set it for a sender that adds a timestamp but cannot
sign would have had every deploy notification refused after the upgrade. It
means the secret header plus a fresh timestamp again. Signature-only, the
setting that stops a replay, is DEPLOY_WEBHOOK_REQUIRE_SIGNATURE, on the
compose whitelist, in the env manifest and examples, and in the deploy
guide.
Forwarding headers were believed from any connection on a private address.
Behind Docker Desktop, OrbStack and docker-proxy every connection to a
published port arrives from the gateway, a private address, so a caller
reaching the port directly could again choose the client address that rate
limits, the audit log and sign-in notices record. TRUSTED_PROXY_CIDRS
(comma-separated CIDRs) now names the proxies: when set, only those peers may
report a client address. The private-range default stays when it is unset,
the boot log states the rule in force in one line, and the reverse-proxy
guide says what to set for a proxy on the same host, on a Docker network, or
on a public address (which, unlisted, puts all clients in one bucket).
An invalid TRUST_PROXY_HOPS threw on every request that resolved the client
address, so every route answered 500, the health probe included. It now
resolves no address, warns once, and is named at boot.
The cross-site write check let through any request that carried an
Authorization header, while the caller is resolved from the session cookie
before any header. A browser attaches Basic or Negotiate credentials on its
own once a proxy or host asked for them, so a cookie-authenticated write from
a sibling subdomain could pass. Only Authorization: Bearer is exempt now, and
only when no session cookie rides along; a request carrying both is checked
as the cookie request it resolves to.
The share-link passphrase POST under /api/c/ is exempt by path: its
credential is the token in the path and the passphrase in the body, and from
the shared view's no-referrer page a browser without Sec-Fetch-Site sends
Origin: null, which was refused.
A cookie named healthlog_session can be set by any host under the same
registrable domain, so a page on a sibling subdomain could plant a session of
its choosing in a visitor's browser. Wherever the session cookie is Secure it
is now issued as __Host-healthlog_session, which a browser accepts only from
this exact host. Plain-HTTP installs, which cannot hold a __Host- cookie,
keep the old name.
Nobody is signed out: the old name is still read after the new one, a
session found under it is re-issued under the new name and the old cookie
expired, and a browser holding the new cookie is never answered from the old
one. Every reader and writer goes through one module, which the proxy, the
native-caller check, the native handoff and the OIDC callback use; the
session-surface guard follows the new reader.
A read a person started now runs as interactive work of their account, and
the document jobs as background work of theirs, so the reader's queue can
order and cap them. When the reader is busy or stopped before it answered,
a lab scan, label read or document read fails with aiRuns.readerBusy (503,
nothing read or charged) instead of a misleading unreadable-file error, and
the index and summary jobs throw so the queue runs them again rather than
recording an outcome about the document.
Three defects in the bounded document reader.
Image uploads were decoded into their thumbnails in the server process. A
header check is all that stood between a decoder and an allocation the file
chooses, and the GIF check showed how that fails. The image is now decoded in
the same child process PDFs run in, under its memory ceiling and time limit;
the header check stays in front of it.
The reader's one slot went to whoever asked first, and a waiting item waited
without end, so a few heavy PDFs from one account held everyone's lab scans
behind them. The slot now goes to a read a person is waiting on before
background work, to accounts in turn, to a few waiting items per account, and
an item that waits past its lane's deadline is answered busy, which callers
treat as retryable.
Any child that ended without an answer counted as a document past its limits,
so a kernel kill caused by the container's overall memory marked a good PDF
as permanently failed. Only a bound the reader measured (the sampled memory,
the time limit, the child's heap cap) is final now; any other end is run once
more and then answered interrupted, which the thumbnail job retries within its
ordinary attempts.
The header check before a thumbnail decode read only the GIF logical screen.
A decoder sizes its buffer from the frame's image descriptor, so a file with a
small screen and a huge frame passed the pixel cap and allocated the full
frame. Walk every block, read each image descriptor, size the image by the
largest of screen and frames, and refuse a file that ends inside a header or
descriptor, carries an unknown block, or has no frame.
The reproductive-health page promised that deleting all data or the
account erases at once. Both wait for the grace window now, the nightly
dumps keep a record until they age out, and the old pgdata volume is a
full copy until it is removed; the page says so and how to make deletion
final. The README, the getting-started note on majors, the move guide and
the Unraid and Portainer templates catch up with Postgres 18, the backups
volume and the recovery kit. The demo seed's spread bound leaves room for
the seed's own one-in-150 spread.
Going back to Postgres 16 after a move that stopped half-way left the
moving marker, and the next start emptied the live 16 database and
started a second server on its data directory. db-upgrade now waits for
the database service and does nothing unless it runs Postgres 18.
Using 16 again after a finished move and then updating started the app
on the move-day copy without a word. The marker now records the old
database's last checkpoint, and a later start refuses when it moved on;
the guide says how to move the current database instead. The disk check
leaves room for the first pre-migration dump, and the move check seeds
the old database with v1.45's own migrations.
grep -q stops at the first match, and with pipefail the SIGPIPE that then
ends docker logs read as a miss, so the drill failed on a line that was
there. The Dockerfile notes that the dump directory keeps nothing without
a mount.
The resource-limit cases and two older mocks now pass typed values, so the
file carries fewer as-never casts than before; the outcome list's comment
is a line shorter to keep its file at its length. Both ratchet baselines
are written down, the source size one also for offhost-backup.ts, which
had shrunk without its number following.
The fourth rollback step had been joined onto the paragraph after the
list; it is a list item again, with the way back to the data after it.
The disaster recovery page now says how the server tells admins about
its copies: the recovery readiness card, the recovery kit and the hourly
Backup health notification. The support page put GlitchTip under Admin,
General; the card is under Admin, Integrations, as the deploy runbook
says. The pre-migration dump notes say that without the backups volume
no dump is taken, also where the image's own directory is writable.
The restore refuses a file that carries any document as metadata only
(findIncompleteDocument), whatever the account holds; the page said it
refused when the account held a document.
The compose comment still called DEPLOY_WEBHOOK_REQUIRE_TIMESTAMP a
requirement for a fresh timestamp header, which the route stopped
accepting in strict mode once requests could be signed, and the env
manifest named only the secret header and lacked the strict switch. Both
now say what the route checks: the secret header, which has no replay
protection, or X-Deploy-Webhook-Signature over the timestamp and body,
and that the strict setting takes signed requests only. The development
example says the same and points at the deploy runbook instead of a page
that no longer exists.
The flag makes the app believe CF-Connecting-IP from every connection,
before the peer check and whatever TRUST_PROXY_HOPS says, which is safe
only when nothing but Cloudflare can reach the origin. The reverse-proxy
page now says so with the ways to get there, the compose comment and both
example files carry the same condition, and the variable is in the env
manifest. The page's list of peers whose forwarding headers are read now
matches the code: loopback, 0.0.0.0/8, private, CGNAT, link-local,
unique-local and site-local, the reserved blocks and multicast. Those last
two stay trusted, since no internet host can connect from them; a test
pins every listed range and the Cloudflare precedence.
A text read that crossed the isolated reader's memory or time bound came
back as a plain read error, which the index job records as decrypt-error,
so the document said its stored file could not be opened. The local
extractor now answers resource-limit for PdfResourceLimitError, the index
records it under that name, and the detail view says the PDF is too large
or complex to read here, in every locale. Like the thumbnail's refusal of
the same bytes it is final: nothing retries it on its own.
Only the backups page said when the bucket's lifecycle rules left
database/ out, so every dump, and every deleted account inside it, stayed
in the bucket forever without anyone being told. Readiness gains a
dump_retention signal that reads the same cached lifecycle probe: attention
when dumps go off-host and no rule covers database/, ok with the expiry
when one does, quiet when the bucket will not say, inactive without a
bucket or without off-host dumps. The hourly evaluation pushes it to the
admins like every other signal.
The image creates DB_BACKUP_DIR owned by the app user, so an install that
runs it without the backups volume could write there, and every nightly and
pre-migration dump landed in the container's own layer. The next update
threw them away while the admin page, the boot line and the readiness card
called them kept on this server.
A dump directory now counts as kept only when it survives the container:
inside a container (Docker, Podman, Kubernetes, a container cgroup or an
overlay root) the directory must sit on a mount of its own that is not a
tmpfs, read from /proc/self/mountinfo with a device-number fallback;
outside one, a writable directory is a disk. Otherwise no dump is written
there: the nightly run uploads off-host only and records not_persistent,
the pre-migration dump is skipped with a warning, the boot line says the
directory is inside the container, the backups page stops promising local
dumps and ignores local-only ledger rows, and readiness fails with no
bucket and notes the bucket-only setup otherwise.
The Unraid template gains a path for the dumps, the Unraid and TrueNAS
pages say why it is needed, and the restore drill first runs the stack
without the volume and checks that nothing is kept or claimed.
The deletion revokes every session, refresh token and API token, so they
answer like any revoked credential; only new sign-ins get the 403
auth.account.deletion_pending, through the shared login response.
The translation files merge key by key (no key changed on both sides), the
backups list carries both the database dump and the pre-wipe copy window,
and the backup-restore doc keeps the shorter rewrite plus the dump in the
bucket and a lifecycle rule that covers database/.
With the real dump health wired in, an empty test database also reports
a missing dump. The file follows the weekly copy alone; the dump signal
is judged in the readiness unit tests.
When the grace window ends for an account that has become the last
active guardian of a managed profile, the purge job refuses to erase it
and the account stays locked. Until now only the worker error log said
so. Every admin now gets one localized notification naming the account
and the ways out (another guardian, deleting the profile, or undoing
the deletion). An audit row on the account records that it was reported,
so the hourly retries stay quiet; a deletion undone and asked for again
is reported afresh.
The undo confirmation in the admin users list now says that sign-in
works again but API tokens, share links and trusted devices stay revoked
and have to be set up again (for a managed profile: its share links and
tokens).
The backups page stated "Retention: 90 days", from a constant whose
comment said it matched a backup-prune job. There is no such job: nothing
deletes a stored copy by age. The weekly copy is replaced in place, one
per account; the copy taken before "Delete all data" is deleted by the
account-deletion purge when the grace window ends; an uploaded copy stays
until its account is erased.
The list now carries preWipeCopyDays (the grace window, 0 when no such
copy is taken) instead of retentionDays, and the page says exactly the
three facts above, in every language.
Also drops a re-export of the JSON import row limit nothing imports.
The shared backup reader kept documents without their stored bytes but
kept every ECG strip whole, trace included. A long watch history is
hundreds of strips of tens to hundreds of kilobytes each, so an upload,
preview or restore of such a copy held the whole history in memory.
The first read now keeps each strip without its trace (a short stand-in,
after the key it was written under is recorded and its form checked),
and forEachEcgTrace reads the traces again one strip at a time. The ECG
restore writes each strip from that second read, as the document restore
already did, and refuses a file whose two reads disagree on the count.
The upload memory test gains an ECG-heavy file: 150 strips, about 200 MB.
The old reader held 197 MB of it and failed the 48 MB bound; the new one
holds about 1 MB, also under a 524 MB heap.
A switched-off scheduled dump is attention now, sent once and never
reminded, with how to turn it back on (DB_BACKUP_ENABLED). Dumps are on
by default, so off is a choice that leaves no copy able to rebuild the
host. An install that never wrote a dump and has nowhere to write one
stays quiet.
The out-of-date kit notice says what changed: the kit now also lists a
key the last confirmation did not cover, for example API_TOKEN_HMAC_KEY
on an instance upgraded from the one-key step, and that nothing broke.
The French kit and readiness strings use vous, the form the rest of the
French bundle uses.
The Postgres major-upgrade guide suggested removing the old pgdata volume
"when you are sure". That volume is a full copy of the database as it stood
before the move: account deletions, trash purges and key rotations after it
never reach it. The guide now says so and makes removing it part of the
move.
The browser error relay forwarded anything posted to it into the operator's
GlitchTip without a session, limited only per address, so anyone could
fill the incident list. Separately, a Prisma client error prints the
failed call into its message and stack, with the arguments object (a
reading's value, a note's text) when no source map is at hand, and the
server sent that to GlitchTip and the logs after a credential scrub that
does not look for it.
The relay now needs a signed-in session and is limited per account; errors
on pages before sign-in go unreported. The central redaction cuts a Prisma
call's printed arguments, keeping the call, a reason line that names a
field, and the stack frames, and the GlitchTip sender applies the
redaction to every event at the egress boundary, whichever caller built it.
The deploy-status webhook authenticated with a static secret in a header,
and the timestamp the docs called replay protection was covered by nothing:
whoever captures one request holds the secret and can send a fresh request
with any content. The strict setting, documented as closing the replay
window completely, only made that timestamp mandatory.
A sender can now sign instead: X-Deploy-Webhook-Signature is the
HMAC-SHA256 of the timestamp and the exact body under the shared secret,
with the timestamp within five minutes, and the secret never travels. The
strict setting accepts only signed requests. The secret header still works
by default for senders that cannot sign, and the docs describe its
timestamp as the staleness hint it is.
safeFetch with requirePublicHost vetted the first URL and pinned DNS
answers in the connector, but Node never looks up an IP literal, so a
followed redirect to a literal private or metadata address was dialled
unchecked. No caller follows redirects to a user-chosen host today; the
floor did not hold for the next one that would.
With requirePublicHost, redirects are now followed one hop at a time and
every location goes through isPublicUrl before it is dialled, at most five
hops. isPublicIp also refuses the benchmarking, protocol-assignment,
multicast, reserved and broadcast IPv4 ranges, site-local and multicast
IPv6 and the IPv4-translated spelling of a private address, and isPublicUrl
strips a trailing dot before the hostname denylist.
The quick-answer route charged one per-address bucket before it read the
token. Where the client address cannot be read, every caller shares that
bucket, so two junk requests a minute switched off every person's
notification quick answers.
The token is an HMAC and is now checked first, which costs one hash and no
database read. A genuine token is limited per account; anything else is
limited per address in a separate bucket that genuine answers never draw
from.
The proxy matcher left out every path ending in an image or text extension
so static files skip it. The exclusion was not anchored, so an API path
whose last segment the caller chooses (a custom tag name ending in .png)
skipped the proxy too, and with it the demo-mode write refusal, the
worker-only refusal and the security headers. Authentication was unaffected.
The extension exclusion now applies outside /api/ only.
The MCP server instructions promise that the person's free text comes back
wrapped in USER_TEXT markers, but get_medication_schedule returned
medication names and doses as plain strings, and get_labs returned analyte,
panel and unit names that can come straight out of an uploaded document.
Text written to read like an instruction reached the connecting client's
model unmarked. The marker scrub also removed only the exact uppercase
spelling, so a lower-case or spaced marker survived inside fenced text.
Both tools now fence those fields, and the scrub removes a marker in any
case and with any spacing inside the brackets.
A token scoped to one medication got 404 for a name that matched none of
the owner's medications and 403 for one that matched outside its scope, so
it could confirm which medications exist by name. Its idempotency replay
also ran before the scope check and returned any of the owner's doses
stored under the key.
A token without the wildcard now gets the same 403 for both, the replay is
looked up only after the scope check, and a key already spent on another
medication answers 409 without that dose. The wildcard token keeps its 404.
A share link gated its report on the doctorReport module but listed and
served its attached documents unconditionally, although the comment beside
the gate said the documents kept a gate of their own. An owner who switched
the documents module off still had every attached file decrypted for anyone
holding the link and its passphrase.
The share page lists no document while the module is off, and the document
route answers 404, the same as for an unknown document, before it looks the
membership up.
Dynamic client registration is open by specification and the client names
itself, so anyone could register under a well-known assistant's name with a
callback on a host of their own and send a signed-in person the authorize
link. The consent page showed the borrowed name and "Unverified
application", never where the code would be sent.
Every consent page now says where the access goes: the callback's host, or
an application on this device for a loopback callback, and the Allow button
names the host. For a self-registered client whose callback leaves the
device, a warning that names the host leads the page, above the
self-reported name. Registration stays open: the hosted assistants register
this way with their own https callback.
The session cookie is SameSite=Lax, and SameSite compares the registrable
domain, so a page on a sibling subdomain of the instance could send a
CORS-simple POST with the person's cookie attached. safeJson accepted any
Content-Type containing "application/json", so a text/plain body that
mentions it in a parameter, which needs no preflight, was parsed as the
person's own request: readings added, entries deleted, integrations
disconnected, a delegate invited within the re-proof window.
apiHandler now refuses a POST, PUT, PATCH or DELETE before authentication
when the browser marks it Sec-Fetch-Site same-site or cross-site, or, from
a browser that sends no fetch metadata, when its Origin names a host other
than the one the request went to or APP_URL. A request with an
Authorization header, or with neither header (the phone app, scripts,
webhook senders), is unaffected, as are the webhook and URL-credential
routes that authenticate with their own secret. The JSON media type is
compared exactly, with parameters allowed, in safeJson and in every route
that branched on a substring of it.
