…inism This PR hardens the ACK workspace by remediating a critical authentication bypass in the API utilities and addressing build determinism issues. Key Changes: Authentication Bypass Removed: Deleted the ALLOW_UNSIGNED_PAYLOADS fallback in tools/api-utils/src/middleware/signed-payload-validator.ts. The middleware now strictly requires a cryptographically signed JWT envelope and no longer trusts spoofable X-Payload-Issuer headers with raw bodies. Build Determinism: Replaced bare tsdown invocations with tsdown --config-loader tsx across package build scripts to resolve missing unrun peer dependency failures. Documentation Updated: Scrubbed README.md, example-identity.mdx, and .env.example to remove cURL examples and configuration instructions that advertised the unsigned authentication bypass.

How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to The PR removes the unsigned-payload path, but its updated issuer and demo documentation still contains contradictory authentication and response guidance, broken MDX formatting, an invalid credential context value, and non-runnable JWT examples. These issues can mislead integrators and prevent reliable use of the documented flows, so merge should wait for corrections or explicit owner acceptance. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

In `@docs/demos/example-identity.mdx`:
- Around line 45-60: Update the API response documentation to limit the { ok,
data } envelope to credential endpoints, and document GET /status/:listId as
returning a bare BitstringStatusListCredential and GET /.well-known/did.json as
returning a bare DID document.
- Around line 41-42: Update docs/demos/example-identity.mdx at lines 41-42 to
remove unsigned-payload bypass guidance, state that the relevant mutation
endpoints require signed JWT payloads, and replace the ControllerCredential,
controller-revocation, receipt, and receipt-revocation examples at lines 71-80,
99-107, 117-128, and 147-155 with signed-payload requests. Update
examples/issuer/README.md at lines 34-36 to remove bypass configuration and
header guidance, and replace the corresponding four unsigned mutation examples
at lines 89-98, 148-156, 193-206, and 258-266 with signed-payload requests.
- Around line 159-168: Update the initial status-list cURL example to use the
zero-based first-list ID `/status/0` in `docs/demos/example-identity.mdx` lines
159-168 and `examples/issuer/README.md` lines 297-302; both sites require the
same direct change.
In `@tools/api-utils/src/middleware/signed-payload-validator.ts`:
- Around line 59-69: Update the issuer validation in the signed-payload
middleware to throw unauthorized("Invalid issuer") instead of a plain Error, and
import unauthorized from ../exceptions so invalid issuers are mapped to an HTTP
unauthorized response.

Inline comments:
In `@docs/demos/example-identity.mdx`:
- Around line 64-69: Replace the shared invalid JWT placeholders with
endpoint-specific signed examples, or clearly label them non-runnable:
docs/demos/example-identity.mdx lines 64-69 ControllerCredential, 84-89
controller revocation with credential ID, 97-102 receipt with documented payment
claims, and 117-122 receipt revocation with receipt ID;
examples/issuer/README.md lines 67-75 match controller and subject, 112-120
match the revocation payload, 148-156 match the receipt request schema, and
195-203 match the receipt ID payload.
- Around line 26-30: Update the Server section in the MDX documentation to
restore the missing code fences: close the shell fence after pnpm run setup,
wrap each command and response example in its own appropriate sh or json fence,
and render { ok, data } as inline code so MDX does not interpret it as an
expression.
In `@examples/issuer/README.md`:
- Around line 29-43: Update the response-format section in the README to scope
the { ok, data } or { ok, error } envelope to credential endpoints only, and
explicitly identify the two bare-document endpoints documented later as
returning unwrapped status or DID documents. Keep the existing envelope examples
unchanged.
- Around line 25-27: Update the API authentication statement in the README to
require signed payloads only for mutation endpoints, while leaving the
documented GET credential, status, and DID examples unchanged.
- Around line 213-228: Update the JSON response example’s `@context` value to use
the bare https://www.w3.org/2018/credentials/v1 URI instead of Markdown link
syntax, while leaving the surrounding credential fields unchanged.
