The GraphQL endpoint built its gqlgen server with bare handler.New and
no limits, so a single request with thousands of aliased resolver calls
was parsed, validated, executed, and marshalled in full. Under load this
let an unauthenticated client drive excessive CPU and memory use against
POST /api/connect/v1/graphql and the console and trust endpoints, which
share the same constructor (GHSA-prh2-g8pv-m7p9).
Add configurable guards in the shared gqlutils.NewHandler: a parser
token limit rejects oversized queries at lex time before any execution,
a fixed complexity limit caps field-selection count, an LRU query cache
avoids repeated parsing, and field suggestions are disabled. The limits
flow from a new APIConfig.GraphQL section through server and api config
into all three GraphQL handlers, with PROBOD_API_GRAPHQL_* env vars and
Helm values exposed for per-environment tuning.
Defaults are sized with generous headroom over real traffic: the parser
token limit (15000) and complexity limit (2000) sit far above the
largest legitimate frontend query yet well below the proof-of-concept
flood, so normal usage is unaffected while floods are rejected cheaply.

Switch the trust center API to resolve aliased nodes via the
resourcealias service instead of the trust-center-specific alias
resolvers.

Trust GraphQL and MCP still exposed presigned URL strings for
trust-center logos while console and connect already serve stable
File.downloadUrl paths. Phase 1 migrates the seven public logo
fields on trust GraphQL and the trust-center file references on MCP
to the shared File type; trust GraphQL NDA stays on fileUrl for a
follow-up.
Trust resolvers load public files through filemanager and map them
with types.NewFile. The trust app Relay queries and components now
read logo.downloadUrl. MCP specification, resolvers, and helpers
are updated in sync, including NDA on MCP where callers already
have file access.
filemanager is split into focused files and its URL surface is
narrowed to GenerateFileURL(file) for stable app URLs and
GeneratePresignedURL for S3 redirects. GetPublicFile remains the
DB entry point when only a file ID is known.
Add trust and MCP e2e coverage for public logo download URLs.

The session-transfer route was registered before the session and member
provisioning middlewares, causing chi to panic with "all middlewares must
be defined before routes on a mux". Scope the middlewares to the graphql
route using r.Group so session-transfer remains unauthenticated.

The session transfer handler was blindly redirecting to the continue URL
from the signed token. Use saferedirect with a trust center domain check
to prevent open redirects, and only trigger session transfer for known
trust center custom domains instead of any non-base-URL host.

After OIDC login, if the redirect targets a trust center custom
domain, the callback now redirects through a session-transfer
endpoint on that domain. The endpoint verifies an HMAC-signed,
time-limited token and sets the session cookie on the custom
domain before redirecting to the final URL.
The continue URL is bound into the signed token payload to
prevent open-redirect attacks via parameter tampering.
