* feat: let the Contact Us form carry screenshots and recordings
The form doubles as our bug-report channel, and the bugs worth reporting
are often the ones that need a picture: a visual glitch, or something that
takes five steps to reach. Up to 5 images or videos may now ride along
with the message, delivered as attachments on the support email.
Nothing the client says about a file is believed. The endpoint takes bare
base64 and re-derives all three of the things that matter from the decoded
bytes:
- Type, sniffed from magic numbers and matched against an allow-list of
PNG/JPEG/GIF/WebP and MP4/QuickTime/WebM. A declared MIME is never read,
so it cannot smuggle anything past the list. SVG is excluded on purpose
(it carries script, and support tooling renders what it is sent), as are
the non-video brands that share MP4's `ftyp` box -- HEIC, M4A, JPEG 2000.
- The file name, reduced to a display label with the extension taken from
the sniffed type. PNG bytes named `payload.html` arrive as
`payload.png`; a name can never carry the CR/LF that would break out of
a Content-Disposition header, nor the bidi overrides that make
`report<RLO>gnp.exe` render as `report.exe.mp4`.
- Size: 10 MB per file, 15 MB per submission, counted on decoded bytes.
Encoded length is capped before decoding, so an oversized payload costs
a length check rather than a 10 MB allocation. The total stays well
under the 25 MB most providers enforce, since the outgoing mail base64s
these again.
Base64 is decoded strictly, reusing the round-tripping decoder that
already guards app icons -- `Buffer.from(s, 'base64')` silently drops
characters it does not recognise, and the round-trip is what rejects
bytes smuggled after the payload. That decoder and the image sniffer move
from appIcon.ts to a new mediaSniff.ts, which gains the video counterpart.
One request is now worth megabytes of parsing and outbound mail, so the
existing per-user rate limit gains a per-IP backstop (which the per-user
counter cannot see through freshly minted accounts), a concurrency cap,
and a Content-Length gate that refuses an impossible body before anything
decodes it.
Payloads are not stored. They ride the email; the new
`feedback.attachments` column records names, types and sizes only, so an
abusive submission stays attributable once the mail has been dealt with.
Also fixes the form posting an empty message when Send was pressed with
nothing typed, and surfaces submit failures instead of leaving the button
disabled with no explanation.
* fix: stream Contact Us attachments as multipart instead of base64 JSON
Base64 in a JSON body went through the global JSON parser before the route
ran: raw buffer, rawBody copy, decoded string, parsed strings, then decoded
Buffers plus a re-encode for the strict check. A max-size submission peaked
around 110-135 MB of heap for 15 MB of files, and the route's Content-Length
check ran after all of it.
Attachments now arrive as multipart/form-data, which the global parser skips.
Auth, rate limit, concurrency and the Content-Length 413 all run before the
body is read, and busboy enforces the count, per-file and total caps while
streaming, so only the decoded file bytes are held (~16 MB peak). On a broken
limit the reader stops and the response closes the connection.
JSON stays supported for message-only posts; a JSON `attachments` field is
rejected.
* fix: deliver Contact Us 413s instead of resetting the upload
Closing the socket on a mid-stream limit sent the 413 and then reset the
connection with the client still uploading, so the client could see a
reset instead of the error. After a limit trips, the rest of the body is
now read and discarded, bounded by the body budget; past the budget the
request is destroyed.
Adds an HTTP-level test through the full middleware stack (FormData
upload, unauthenticated refusal, 413 on declared length before the body
is sent, 413 on a chunked upload over the per-file cap), trims comments
to the AGENTS.md length rule, and drops a box-drawing test divider.

Browser uploads (Dev Center deploy, puter.fs.upload) PUT file bytes
directly to presigned URLs on the public S3 endpoint. That cross-origin
PUT is preflighted, and the bucket had no CORS rules, so RustFS answered
without Access-Control-Allow-Origin and the browser blocked the upload.
s3-init now runs put-bucket-cors on every boot after ensuring the bucket
exists (idempotent). Origins are open because the presigned URL is the
credential and the SDK sends no cookies. Document how to re-run and
verify in doc/self-hosting.md.
* fix(kv): keep disableSharing entries out of other apps' events (PUT-1876)
Private kv keys and values are no longer delivered to cross-app subscriptions, including forwarded and durable deliveries.
* fix(fs): refuse usernames whose home path still holds another account's rows (PUT-1877)
Username claims (signup, save_account, change-username, OIDC, team provisioning) now also check for leftover rows under /<name>/, and the root listing only returns the actor's own home.
* fix(puter-js): reconnect the events channel after a server-side disconnect (PUT-1881)
A server hang-up is retried with a bounded backoff; persistent handlers survive it and get an optional onError when the connection can't be restored.
* fix(backend): let the graceful shutdown finish before telemetry exits (PUT-1948)
The telemetry preload no longer exits on signals; the entry point drains, tears down top-down, flushes telemetry last, then exits. DB pools stay open until teardown.
* fix(fs): reserve quota for signed uploads in progress (PUT-1880)
startWrite/startBatchWrite hold each upload's declared size in a per-owner cache reservation until it completes, aborts or expires, so a burst of starts can't all read the same committed usage. Caps in-flight uploads at 10,000 per account.
* fix(fs): refuse to complete a signed upload whose object never arrived (PUT-1951)
Completion now 400s when the object store reports the key missing (transient errors stay lenient), abort no longer deletes an object a live entry still uses, and a ghost entry is only removed after a second miss at its recorded location.
* fix(metering): move usage to v2 keys with a small totals item, per-model detail shards and a 3-month TTL (PUT-1949)
The billed item holds only totals; per-model detail lives in 100 hash-sharded items read in one batch and cached for 60s, and more than 5,000 distinct usage types in a month fold into other. Global and per-app aggregates store totals only, appTotals comes from a prefix listing, a refused path only skips the key that refused it, exact reads near the allowance are throttled per key, and every metering record expires after 3 months. September usage restarts at deploy; the monthly-charge claim stays on the v1 key through September so recurring charges don't fire twice.
* test(events): let the worker backoff test tolerate a loaded run
* feat(events): scale KV event fan-out with the key owner's plan
A KV change delivers to up to 512 matching subscriptions (2,048 filter evaluations) for a paid key owner and 128 (512) otherwise, inline values are dropped once more than 128 match, and paid accounts may hold up to 512 share handles per app. The owner's plan is only looked up when a change has more candidates than any cap.
* test(metering): seed the 150-app listing test directly so it fits under coverage
Closing an account that owns a team left `owner_user_id` NULL while
`deleted_at` stayed NULL, so the team remained live while every team
route resolves by membership — which the deletion cascades away. The team
could then not be administered by anyone, and the accounts it provisioned
could not be closed. Declined now in both directions: live teams via
`countOwned`, and soft-deleted ones still holding accounts via a new
store read, since a deleted team's accounts are suspended rather than
removed.
The cap lock gave up after 200ms and proceeded unserialized, so
overlapping provisioning could each read the seat count before any insert
committed. It declines instead; a single create never contends. An
unreachable lock backend is a 503 rather than a silent pass.
An account a team provisioned can no longer create a team of its own
(PUT-1890) — that is not the intended lifecycle, since such accounts do
not go through the normal sign-up path. Keyed on `org_owned = 1`, so the
owner and joined members are unaffected, and not via `teamsAvailableTo`,
which is permissive by design.
The directory declines scoped access tokens, as `listMembers` already
bounds non-account callers.
* fix(tools): spawn npm.cmd through a shell on Windows
* fix(tools): join the npm command line on Windows to avoid DEP0190
Passing args alongside shell: true warns on Node 24. Test the spawn
tuple as data and run a real npm spawn instead of mocking child_process.

* feat: allow browser extension origins in auth requests
Add chrome-extension://, moz-extension://, safari-extension://, safari-web-extension://, and extension:// to the protocol allow-list so browser extensions can obtain app tokens via /auth/get-user-app-token.
Extract WEB_AND_EXTENSION_PROTOCOLS constant in validation.js so the allow-list is defined once and shared by AuthService, AppStore, and AppDriver.
* fix: harden the extension-origin allow-list
Review follow-ups on the extension-origin change:
- Require a host in `validateUrl`. Only "special" schemes need an
authority, so `chrome-extension:` parsed with an empty hostname and
slipped past the reserved-system-host guard in AppDriver.
- Lowercase the host in `AuthService#normalizedOrigin`. `new URL()`
lowercases http(s) hosts but leaves opaque ones alone, so one
extension in two spellings resolved to two app uids — two AppData
trees, two permission sets — and missed the origin blocklist.
- Drop `extension:`. No browser emits it, and it accepted
`extension://evil.com` as an app origin.
- Freeze the allow-list and derive `validateUrl`'s http(s) default from
`WEB_PROTOCOLS` so the two spellings can't drift apart.
- Pin the tests to the real uid derivation, use unique extension ids so
a row left by another test can't mask the bootstrap path, and cover
the host-less and near-miss schemes.
- Fix the prettier/eslint failure in AppStore.js.

Signup links can carry a bonusCode. Core checks its shape and previews it through `puter.signup-bonus.check`, refuses a dead code before the abuse hook records the attempt, then hands a live one to `puter.signup-bonus.validate` after `puter.signup.validate`, which may raise the phone/card gates; the accepted code rides on `puter.signup.success`, and OIDC carries it in the signed state. `user.card-verified` is now awaited like `user.phone-verified`. The signup form shows the offer and sends the code.
Tokens under the `oidc-state` scope share one signing key, so the payload is
what says which job a token belongs to. The popup-return proof now carries a
`purpose` claim, and each verifier accepts exactly one kind of token.
The return leg also sets a single-use companion cookie, mirroring the nonce
`/start` already uses, and stamps the action its redirect lands on. Redeeming
a proof requires the matching cookie — consumed on success only, so a rejected
call can't invalidate an in-flight return — and the popup honors only a proof
minted for its own action.
The cookie is host-only, so `/auth/oidc/verify-popup-return` is also served on
the GUI origin and the popup redeems it same-origin. The return leg always
lands the popup on `config.origin`, where both the cookie and the route live.
* fix: new cache costs for claude
* fix: refuse app-issued scoped tokens on events handler and worker routes
An access token an app mints (e.g. a getReadURL() token) resolves
effectiveApp to the issuing app, so #handlerApp and listEventsWorkers
treated it as the app: it could publish, remove and list handlers, and
list or destroy the app's worker, regardless of its permission manifest.
Refuse any scoped token there, as the kv-handle routes already do.
* test: freeze the clock before the first backoff read in workerInvoker
The first hold was read on real time, so a slow run measured the 2s
backoff as 1s.
A public origin-bootstrap app row planted on an alternate hosting domain
could resolve ahead of the owner's private app and skip the private
access gate (PUT-1883).
- get-user-app-token canonicalizes hosted-subdomain origins before uid
derivation and bootstrap, so every hosting variant shares one app row
- the app create/update conflict check crosses hosting-domain variants,
so an existing alt-host stub is absorbed by the owner's create
- resolveOwnedAppForHostedSite and the canonical-uid lookup order
matches private-first with a deterministic id tiebreak
- GET /teams and /teams/:uid/members admit apps for teams whose owner opened
the directory; apps get active members' usernames only
- events.workers.list() from an app returns only its own worker
- hide account-session-only SDK methods from the public types
- unpublish the updateProfile docs page (redirects to getProfile)
- revokeReadURL() works through a new /auth/revoke-own-access-token route
* feat(ai): sync GPT-6 Sol, GPT-6 Luna, and Claude Opus 5.5
* chore: remove documentation changes from model sync
* fix(ai): bill OpenAI cache writes and long-context pricing
GPT-5.6 and later bill prompt-cache writes at 1.25x input and report them
in `cache_write_tokens`, inside the input total. Both OpenAI calculators now
split them out of the prompt count and meter them under their own key, and
the six GPT-5.6+ models carry the rate.
GPT-6, GPT-5.6, GPT-5.5 and GPT-5.4 (incl. Pro) bill a request with more
than 272K input tokens at 2x input (cached reads and cache writes included)
and 1.5x output for the whole request. Models declare this as
`long_context_pricing`, and the ledger overrides, the reported `usd_cents`
and the credit gate all apply the multipliers.

* fix(ai): bill GPT-5.6 Sol at OpenAI's promotional pricing
The catalog carried GPT-5.5's $5/$0.50/$30, but OpenAI bills GPT-5.6 Sol
at $4/$0.40/$20 per million input/cached/output tokens, promotional
through at least 2026-11-21. PUT-1943 tracks re-checking before then.

`ExecService.launchApp`, reachable from `puter.ui.launchApp`, launched any
named app with no check on the target. Gate it: a godmode target may only
be launched by a godmode caller. Desktop launches (tile, double-click,
URL) call `launch_app` directly and are unaffected; `connectToInstance`
already had its own allowlist.
A root was free to be renamed or moved, so it could be parked on a
username no account held yet. The next account to take that name
provisioned a second root at the same path, and from then on either row
could answer a lookup of it — new entries inherit their owner from
whichever row resolved as the parent, so one account's files were
created owned by the other, and renaming the parked root dragged the
other account's subtree along with it.
Rename and move now refuse a root, every username claim checks the home
path before the user row is written, and renameUserHome refuses to heal
onto a path another account holds.
- ProfileService keeps each profile as /system/profiles/<uuid>.profile,
admin-owned and served by the protected puter-profiles subdomain
- GET/POST /profile; puter.auth.getProfile/updateProfile, with
getProfilePicture reading through them
- another user's profile is served only while its owner is on a paid
plan (profileGate.enabled kill switch); the hosted file is gated
through the new site.access.check hook the hosting middleware asks
before streaming any file
- SubdomainStore.create takes isProtected
- the GUI reads and writes the profile through the SDK
- docs: getProfile, updateProfile, UserProfile, limits
PUT-1859 PUT-1860 PUT-1861 PUT-1862
The clickjacking guard in #3912 pinned `event.source` to `messageTarget`,
which is only assigned when `env === 'app'`. On a third-party site it is
undefined, so the UI listener dropped every message and
showOpenFilePicker, showSaveFilePicker and showDirectoryPicker never
settled.
Split the two environments. `app` still pins the host frame, whose origin
is whatever the deployment is served from. `web` has no host frame — the
picker popups post back directly — so pin the GUI origin we opened them
on, plus the set of popups we opened. Origin pinning is safe there,
unlike the parent-frame case, because we chose the URL, so self-hosted
and local deployments keep working.
Falls back to the origin alone when `event.source` is null: the picker
calls window.close() right after posting and a discarded browsing
context can drop the source.
PUT-1867
* fix(ai): send stable, non-sequential user identifiers to AI providers
A precedence bug in the AI providers' identifier expression made every
request send `user: ":undefined"` (the ternary bound the app-uid suffix to
the whole `actor.user.id + actor.app?.uid` sum instead of just the suffix),
or read `actor.user.id` on a missing user. The same expression also shipped
the sequential internal user id, letting AI vendors correlate a single
account across apps and sessions.
All eight OpenAI-, Azure-, xAI-, Meta- and ZAI-style providers now build
the identifier through one shared helper, `aiUserIdentifier()`:
- `puter-<user-uuid>[-<app-token>]`: the random user UUID is always
preserved in full; `maxLength` constrains only the app-bearing form
- app attribution reads `effectiveApp`, so access-token requests name the
issuing app instead of looking like direct user traffic
- the app token is truncated to fit the budget, and omitted entirely when
the remaining budget is below 8 chars, where a truncation could collide
with another app's uid
- nothing is sent for the system actor
- Meta and ZAI keep a caller-supplied `safety_identifier` / `user_id`
override, applied before the helper result
`user` is deprecated by OpenAI; the SDK types direct callers to
`safety_identifier` (abuse detection) and `prompt_cache_key` (cache-hit
bucketing). The four OpenAI/Azure chat providers and MetaProvider now send
`prompt_cache_key` as well, defaulting it to the same per-user identifier
unless the caller supplies one; Azure's Grok branch drops both fields,
matching its rejection of unknown args. The cap comment cites only verified
limits: OpenAI's 64 for `safety_identifier` (from the SDK types) and Z.AI's
6-128 for `user_id` (from Z.AI's docs); Meta and xAI document none, so none
is claimed.
The xAI image `#edit` path now carries the identifier like generation, and
takes a named-options param so `user` cannot be transposed with the
adjacent same-typed `aspectRatio`.
Tests share a four-actor matrix (`user` / `user+app` / `access token` /
`system`) with `assertActorMatrixIdentifiers()` across the six
OpenAI-style suites; the helper has exact-string and boundary coverage
(size caps, zero-budget and sub-base cases, no dangling separator, UUID
never truncated, collision guard); the Azure Grok assertions run under a
real user actor so they cannot pass vacuously. 212 provider-suite tests
pass; typecheck and ESLint are clean.
* fix(ai): lock the vendor identifier down and keep vitest out of the test util
Meta and Z.AI no longer let `custom` override the abuse identifier; it is
Puter's attribution, not the caller's. The shared test util exposes pure
field pickers instead of importing vitest into a file the production
tsconfig compiles. The helper's length-cap comment now matches vendor docs
(Meta does cap `safety_identifier` at 64), the redundant budget branch and
the unused export are gone, and the per-user `prompt_cache_key` trade-off is
stated once in the helper instead of five times in providers.

* fix(ai-image): sync image catalogs, unify request shape, document models
Model sync against every vendor listing and a live generation sweep:
Gemini stable ids replace the retired preview spellings (2.5 Flash Image
delisted ahead of its 2026-10-02 shutdown), OpenAI gpt-image-1/-1-mini/-1.5
are delisted but routable until their shutdown dates with gpt-image-2 as
the default, xAI gains grok-imagine-image-2.0 with its quality tiers,
BytePlus gains the 3K/4K tiers and per-model pixel bounds, Cloudflare
gains SDXL Lightning/Base and SD 1.5 Inpainting, Replicate gains a
schema-driven catalog of 88 additional models with version-pinned
community predictions, and every Together image route is excluded for
the third-party data-sharing requirement.
Request normalization: the driver collapses ratio/width/height/aspect_ratio
into one imageSize with aspect-versus-pixel intent, validates prompt,
quality and resolution once, resolves provider hints (short names or
full driver ids) and aliases with exact ids winning over resellers, and
hands each provider an immutable copy of the caller's args. Providers
share prompt validation, aspect snapping, and content-sniffed data URIs
so responses carry the right MIME type. Replicate predictions are created
once, cancelled on abort or deadline, and bounded in input fan-out.
SDK: txt2img copies caller options, rejects blank prompts with
prompt_required in every call form, and documents that normalize has no
effect because the image return shape is already uniform.
Docs: txt2img options per provider, provider defaults and discovery,
availability notes, a new image model catalog and pricing page, and the
image-generation limits in the quotas page.

* fix(ai-image): sniff SVG outputs correctly, reject hex/exponent dimensions
imageDataUri only decoded the first 24 base64 chars (18 bytes) before
sniffImageMime, which cannot see an <svg> root behind an XML prolog -
SVG outputs from recraft-v*-svg models were being labeled image/png.
Decode enough of the payload to cover the 8 KB SVG sniff window.
dimension() accepted string number literals ('0x10', '1e3') as if they
were decimal dimensions; restrict to plain decimal notation.
* docs(ai): link to the model directory instead of a static catalog
The image model catalog and pricing page duplicated the always up to date
model directory at developer.puter.com/ai/models. Link to the directory
from txt2img-related docs and keep the Together data-sharing exclusion
note self-contained.

The token grant writes `flag:app-is-authenticated` on the user->app row,
but the check asked for `service:<app_uid>:ii:flag:app-is-authenticated`.
Those never match, and the parent walk reduces the question to a bare
`service` — a root every user holds by default — so the check answered
true for any app_uid and handed back an app-under-user token for an app
the user had never opened.
Read the row the grant writes, through one shared constant so the two
cannot drift again, and mint against the resolved uid.
A cancelled account picker no longer leaves `popup_signin_consent` set:
with no relationship there is no token to flip it.
Chat and video drivers keyed their provider and model maps on plain objects,
so `model` or `provider` values such as `__proto__` reached Object.prototype
and surfaced as 500s. Both maps are now null-prototype objects and reject
those names as ordinary unknown models.
txt2vid now rejects blank or non-string prompts with `prompt_required` before
any request, tolerates `null` in either argument slot, and copies the caller's
options before resolving the `duration` alias and output path so frozen
option objects work and caller objects are never mutated.
