The boundary test was building a cursor without the required `o` key, so
decode failed on the missing-order branch before reaching the µs-overflow
path the test is asserting. Both paths return 400 INVALID_CURSOR so the
assertion passed for the wrong reason. Add `o` to the payload and matching
`order=` to the request so the decode reaches the intended branch.
* ModelPatcherDyanmic: purge stale vbar allocs on force cast
* ModelPatcherDynamic: restore backups before load
If doing a clean reload, mutative changes (lora application) could be
applied on-top of the already loaded weight. Restore from backup
unconditionally so that the new load is clean.
Strip prose references to sibling Go implementations and external
ticket IDs from cursor.py, the cursor tests, the keyset integration
tests, asset_management's sort-field comment, and the legacy
prompt_id alias comment. Pure docstring/comment scrub — no behavior
or wire-format changes. x-runtime: [cloud] field annotations in
openapi.yaml are unchanged; those are the spec's structural
cross-runtime convention, not internal references.
The job_ids query parameter on GET /api/assets is tagged x-runtime:
[cloud] and only exists for cloud's variant of this endpoint. Cloud
removed all consumers and the cloud-side handler/codegen/tests in
Comfy-Org/cloud#3778. With cloud no longer accepting this parameter,
the [cloud-only] documentation here is wrong — drop it so the daily
sync to cloud/services/ingest/vendor/openapi.yaml propagates the
removal.
The operation at POST /api/assets/import was defined as `importAssets`
with a URL-list body shape, but no runtime actually serves that
operation at this path. The cloud runtime serves a different operation
here — `importPublishedAssets` — which imports published-workflow
assets into the caller's library by ID, not by URL.
Cloud's URL-based asset ingestion lives at separate paths
(POST /assets/download + GET /assets/remote-metadata) tracked
elsewhere; nothing in this PR affects that work.
Changes:
- Replace the operation at POST /api/assets/import with
`importPublishedAssets`, taking ImportPublishedAssetsRequest
(published_asset_ids + optional share_id) and returning
ImportPublishedAssetsResponse (list of AssetInfo).
- Remove the unused AssetImportRequest component schema (no other
references in the spec).
- Operation and schemas tagged x-runtime: [cloud] with [cloud-only]
description prefix, matching the existing convention for
cloud-runtime-only operations elsewhere in the spec.
Spectral lint passes (0 errors); the two hint-level findings on
the spec are pre-existing and unrelated.
No FE consumer references AssetImportRequest today; this is a pure
spec correction to match what the cloud runtime actually serves.
Add the OAuth 2.1 authorization flow and RFC 7591 Dynamic Client
Registration endpoints to the shared spec, alongside the existing
auth-tagged operations (/api/auth/session, /api/auth/token,
/.well-known/jwks.json). All tagged x-runtime: [cloud] with a
[cloud-only] description prefix, following the established
convention for cloud-runtime-only operations.
Endpoints:
- GET /.well-known/oauth-authorization-server (RFC 8414 metadata)
- GET /.well-known/oauth-protected-resource (RFC 9728 metadata)
- GET /oauth/authorize (consent challenge)
- POST /oauth/authorize (consent submission)
- POST /oauth/token (RFC 6749 §3.2)
- POST /oauth/register (RFC 7591 §3.1 DCR)
Component schemas added:
- OAuthAuthorizationServerMetadata
- OAuthProtectedResourceMetadata
- OAuthConsentChallenge, OAuthConsentChallengeWorkspace
- OAuthAuthorizeRedirectResponse
- OAuthTokenResponse, OAuthTokenError
- OAuthRegisterRequest, OAuthRegisterResponse, OAuthRegisterError
These endpoints are implemented in the cloud runtime today and
are called by browser frontends rendering the consent UI and by
MCP-spec-compliant clients (Claude Desktop, Cursor, etc.) doing
auto-discovery + self-registration. Documenting them in the
shared spec lets the cloud frontend generate types directly from
this spec instead of maintaining a parallel definition.
Spectral lints clean (0 errors). The hint-level findings on
OAuthTokenError / OAuthRegisterError ("standard error schema")
match the same hint on CloudError — these are protocol-specific
RFC-shaped errors, not generic application errors.
Cursor pagination hasn't shipped on either runtime yet — this PR is
still draft and cloud's mirror is just behind it — so there are no
legacy no-o cursors in the wild. Make o mandatory from day one
rather than landing permissive and tightening later.
decode_cursor now rejects any payload without o (or with a non-string
o) as malformed. CursorPayload.order becomes a required str. Tests
that constructed CursorPayload directly now pass order="desc";
test_legacy_cursor_without_order_accepted flips to
test_cursor_without_order_rejected.
* model_management: disable non-dynamic smart memory
Disable smart memory outright for non dynamic models.
This is a minor step towards deprecation of --disable-dynamic-vram
and the legacy ModelPatcher.
This is needed for estimate-free model development, where new models
can opt-out of supplying a memory estimate and not have to worry
about hard VRAM allocations due to legacy non-dynamic model patchers
This is also a general stability increase for a lot of stray use cases
where estimates may still be off and going forward we are not going
to accurately maintain such estimates.
* pinned_memory: implement with aimdo growable buffer
Use a single growable buffer so we can do threaded pre-warming on
pinned memory.
* mm: use aimdo to do transfer from disk to pin
Aimdo implements a faster threaded loader.
* Add stream host pin buffer for AIMDO casts
Introduce per-offload-stream HostBuffer reuse for pinned staging,
include it in cast buffer reset synchronization.
Defer actual casts that go via this pin path to a separate pass
such that the buffer can be allocated monolithically (to avoid
cudaHostRegister thrash).
* remove old pin path
* Implement JIT pinned memory pressure
Replace the predictive pin pressure mechanism with JIT PIN memory
pressure.
* LowVRAMPatch: change to two-phase visit
* lora: re-implement as inplace swiss-army-knife operation
* prepare for multiple pin sets
* implement pinned loras
* requirements: comfy-aimdo 0.4.0
* ops: remove unused arg
This was defeatured in aimdo iteration
* ops: sync the CPU with only the offload stream activity
This was syncing with the offload stream which itself is synced with the
compute stream, so this was syncing CPU with compute transitively. Define
the event to sync it more gently.
* pins: implement freeing intermediate for pinned memory
Pinning is more important than inactive intermediates and the stream
pin buffer is more important than even active intermediates.
* execution: implement pin eviction on RAM presure
Add back proper pin freeing on RAM pressure
* implement pin registration swaps
Uncap the windows pins from 50% by extending the pool and have a pressure
mechanism to move the pin reservations om demand.
This unfortunately implies a GPU sync to do the freeing so significant
hysterisis needs to be added to consolidate these pressure events.
* cli_args/execution: Implement lower background cache-ram threshold
Limit the amount of RAM background intermediates can use, so that
switching workflows doesn't degrade performance too much.
* make default
* bump aimdo
* model-patcher: force-cast tiny weights
Flux 2 gets crazy stalls due to a mix of tiny and giant weights
creating lopsided steam buffer rotations which creates stalls.
* ops: refactor in prep for chunking
* mm: delegate pin-on-the-way to aimdo
Aimdo is able to chunk and slice this on the way for better CPU->GPU
overlap. The main advantage is the ability to shorten the bus contention
window between previous weight transfer and the next weights vbar
fault.
* bump aimdo
* pinning updates
* specify hostbuf max allocation size
There a signs of virtual memory exhaustion on some linux systems when
throwing 128GB for every little piece. Pass the actual to save aimdo
from over-estimates
* tests: update execution tests for caching
The default caching changed to ram-cache so update these tests
accordingly.
Remove the LRU 0 test as this also falls through to RAM cache.
- Soften offset param prose: it's not deprecated, just not preferred for
sequential walks. Random-access UIs (jump-to-page, item count displays)
legitimately still want offset, so dropping the 'deprecated' framing
rather than promoting it to a machine-readable deprecated:true flag.
- Add explicit HTTP status assertions before every json() / next_cursor
read in test_list_cursor.py so a failing request surfaces as an HTTP
error instead of a confusing KeyError on a 4xx/5xx body.
Address three needs-judgment items from the cursor-review judge synthesis:
1. Cursor wire format now includes an "o" key carrying the sort
direction ("asc" / "desc") it was minted under. A request that
replays the cursor with a flipped `order` parameter is rejected
with 400 INVALID_CURSOR instead of silently walking the wrong
direction. Legacy cursors without "o" still decode (the binding
is best-effort until cloud mirrors the field — follow-up filed
separately).
2. JSON serialization now escapes `<`, `>`, `&`, U+2028, U+2029
to mirror Go's default `json.Marshal` behavior. Without this, an
asset name containing those characters produced different bytes on
Python vs cloud Go. The escaped form is what both runtimes emit.
3. Add direct query-layer tests for the keyset tiebreaker — the secondary
ORDER BY id branch was previously unexercised. Two scenarios: all
rows share a primary sort value, and mixed ties straddle page
boundaries. Both assert no row is dropped or duplicated across the
walk.
Wire-format note: Python cursors now differ from current cloud cursors
by exactly the "o" key. Cloud follow-up will bring the two back into
byte alignment.
- Mint next_cursor on every cursor-supported sort, not only when 'after'
was supplied. A first request (no 'after') previously returned
next_cursor=None, leaving cursor mode unreachable from a clean start.
- Over-fetch limit+1 so an exactly-full terminal page doesn't mint a
spurious cursor pointing at a phantom next page.
- Map crafted out-of-range microsecond cursors (OverflowError / OSError
in datetime construction) to 400 INVALID_CURSOR instead of leaking 500.
- Bump MAX_CURSOR_VALUE_LENGTH 256 -> 512 to match the AssetReference
name column max; without this, a long-named asset minted a cursor the
same server then refused on the next request. Cross-runtime byte
identity with cloud is unaffected because no cloud cursor ever carries
a value > 256 (cloud schema doesn't permit it).
- Return None from _encode_next_cursor when the boundary row carries a
NULL sort value (e.g. an Asset without size_bytes backfilled), instead
of silently encoding 0 and mis-positioning the keyset.
- Fix schemas_in.py comment so it matches actual handler behavior
(last_access_time + 'after' raises 400, does not fall back).
- Add AssetsApiError schema + 400 response to GET /api/assets in
openapi.yaml so generated clients know the INVALID_CURSOR envelope.
- Extend integration coverage: first-page mint, exact-multiple terminal
page, cursor walks for created_at/updated_at/size sorts, datetime
overflow surfaces as 400 not 500.
- Add unit coverage for datetime overflow and 512-char round-trip.
Adds integration tests for: full cursor walk, invalid-cursor 400,
sort/cursor mismatch 400, cursor-wins-over-offset, absent next_cursor
when no more results, and pagination stability across deletes.
list_assets_page accepts an opaque 'after' cursor and returns
next_cursor when more pages are available. The query applies a keyset
WHERE clause and a secondary ORDER BY id for deterministic tiebreak.
Cursor sort field is validated against the request sort, and a
last_access_time sort (OSS-only) falls back to offset/limit. Offset is
ignored whenever a cursor is supplied.
Port of cloud common/pagination/cursor.go. Wire format is base64url of
{"s", "v", "id"} JSON; times are Unix microseconds UTC to match
PostgreSQL timestamp precision.
Includes a byte-identity fixture pinned against the cloud Go wire
format so cross-runtime FE pagination can't silently drift.
Add 'after' query param and 'next_cursor' response field for keyset
pagination. Matches the cloud Go implementation (BE-893) so frontend
sees a unified contract across runtimes. Offset/limit remain as a
deprecated fallback.
Aligns the OSS spec with the cloud-side BE-1004 contract:
- createWorkspaceApiKey request body: add maxLength: 5000 to the
description property (matches cloud's hub_profile.description
MaxLen(5000) convention; enforced cloud-side via handler check).
- WorkspaceApiKey + WorkspaceApiKeyCreated response schemas:
mark description as required (cloud's handler always populates
the field, defaulting to empty string when not supplied on create),
drop nullable: true, add maxLength: 5000 for symmetry, and clarify
the doc string ("Always present in responses; empty string when no
description was supplied on create").
Both schemas are tagged x-runtime: [cloud] at the schema level so the
tightening is correctly scoped — OSS-only implementations are not
required to honor the workspace API keys endpoints at all.

* feat(openapi): add optional description field to workspace API key schemas
Add an optional `description` property (type: string) to three
workspace API key schemas in openapi.yaml:
- Inline request body of createWorkspaceApiKey (POST /api/workspace/api-keys)
- WorkspaceApiKey (list/info schema)
- WorkspaceApiKeyCreated (creation response schema)
The field is not added to any `required` array, making it fully
backward-compatible with existing clients.

* fix(openapi): mark description nullable in workspace API key response schemas
Per CodeRabbit review on PR #13993: the underlying DB column is nullable
varchar (default ''), so the response schemas should permit null to match
stored data reality. Without nullable: true the OpenAPI contract would
require coercion on the handler side or risk a contract violation.
Request schema unchanged — clients shouldn't be sending null on create.
These two fields were added recently to the Asset schema as nullable
integers, with the intent of exposing original image dimensions for FE
consumers (cloud-side thumbnailing makes naturalWidth/Height return
the wrong size for an image card's dimension label).
The implementation effort that consumes them subsequently converged on
a different shape — dimensions nested under the existing free-form
`metadata` JSON field as `{kind: "image", width, height}` — to avoid
introducing type-specific flat fields on the canonical Asset shape,
and to leave room for forward-compatible additions (video duration,
fps, etc.) without further schema churn.
This removes the now-unused top-level fields so the spec reflects the
agreed direction. No other schema definitions reference these fields
directly: AssetCreated, AssetUpdated, etc. inherit Asset via allOf and
do not redefine them.
The runtime ingest implementation that would have populated these
fields was not yet shipped, so no clients are relying on the
top-level shape.

Mark the uploadMask operation as deprecated and point clients at
/api/upload/image. The mask-compositing behavior the endpoint provides
(alpha-compositing the supplied mask onto an original_ref image) is now
expected to happen client-side, with the composited result uploaded
through the unified /api/upload/image path.
The endpoint continues to function for older clients; no runtime
behavior changes ship with this commit. Only the OpenAPI annotation
and the human-facing description are updated.
