WalkthroughThe change expands credential detection and applies sensitive-data masking to streamed payloads, structured errors, relay responses, persisted Midjourney text, search responses, and upstream response headers. ChangesCredential masking
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The change broadens credential masking across relayed errors, but some structured error fields can still pass through unsanitized, allowing upstream credentials in metadata or structured codes to reach clients. This is a concrete security gap requiring owner follow-up before merge, with additional bounded overhead in usage-bearing streaming responses. Sequence Diagram(s)sequenceDiagram

masking for sensitive values in error-shaped chunks and leaving ordinary
usage-bearing chunks unchanged.

- Around line 9-49: Add a want field to the table-driven cases for
MaskSensitiveInfo containing the exact expected masked output for every input,
then assert the returned value equals want using testify/assert. Remove the
log-only leak behavior and retain a deterministic assertion that catches
unchanged or partially exposed short secrets, using testify/require or assert
according to test setup.
In `@relaykit/relayconvert/kitutil/mask.go`:
- Around line 16-38: Update maskBareKeyPattern and maskMoreKeyPrefixPattern to
require a word boundary before every credential prefix, preventing matches
embedded in longer identifiers. Update maskKeyValuePattern to require a word
boundary before its field-name group so words such as “monkey” are not treated
as key fields, and preserve the fixed-case requirement for the AIza prefix
rather than applying case-insensitive matching to it.
- Around line 202-223: Update MaskSensitiveKeys to mask PEM private-key blocks
and every service-account credential field, including client_id, client_secret,
and private_key. Extract the shared credential-masking sequence into
maskCredentials, invoke it from both masking functions, and add regression
coverage for PEM blocks and all service-account fields.
In `@relaykit/types/error.go`:
- Around line 204-213: Update ToOpenAIError and ToClaudeError to mask Message
with MaskSensitiveInfo and mask Type, Code, Param, and metadata with
MaskSensitiveKeys while preserving each field’s JSON type; if any masking or
serialization step fails, return a safe redacted fallback rather than the
unmasked error, while retaining the existing ErrorCodeCountTokenFailed behavior.
In `@service/error.go`:
- Around line 226-231: The TaskError construction should use the guarded
apiErr.Error() accessor for the Message value instead of directly dereferencing
apiErr.Err, preventing a nil-error panic while preserving the existing masking
behavior.

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift
Restrict masking to error-shaped streamed frames. The usage trigger matches ordinary completion chunks when usage reporting is enabled, and both call sites currently invoke masking unconditionally. This can rewrite choices[].delta.content, corrupt valid output such as task identifiers, and impose JSON parsing, recursive traversal, remarshal, and regex work on every text or realtime audio frame. Gate masking on an error marker or non-2xx status, and never traverse assistant content fields.

Mask error fields individually and fail closed.
MaskSensitiveInfo rewrites URL, domain, and IP patterns in Type, Code, and Param. Mask Message with MaskSensitiveInfo, and mask non-message fields with MaskSensitiveKeys while preserving their JSON types. If masking fails, return a safe redacted fallback instead of retaining the unmasked result. Apply this in both ToOpenAIError and ToClaudeError.

Security hardening: when an upstream echoes the channel API key back in an error (common with free/aggregator upstreams and misbehaving proxies), the relay forwarded it verbatim to the client. This masks credentials across every relayed error surface:
message-only chunks are parsed and masked before relay; bare key formats (sk-,gsk_,hf_,xai-,AIza, JWT,pplx-/nvapi-/r8_/GitHub/GitLab tokens,Bearer <v>,invalid key <v>, service-account fields) are covered, including JSON-escaped quoting.code/type/paramand whole serialized OpenAI/Claude errors are masked, not justmessage.TaskErrorWrapperonly masked when the message contained post/dial/http; now masks unconditionally;TaskErrorFromAPIErrormasks too./mj/submit/*,/mj/task/:id/image-seed, and persistedDescription/FailReason(replayed via task fetch) relayed raw upstream bodies without masking./v1/alpha/search(F-65) — 200 bodies wereio.Copy-ed to the client without masking.Authorization/X-Api-Key/Api-Keyetc. in response headers were copied to the client; now blocked (with F-34's header blocklist).A regression fix for the F-20 masking (enum field over-masking) is included.
