In `@client/go/verilink_test.go`:
- Around line 198-216: Add negative coverage alongside the round-trip test for
VerifySignatureInputWithExtra: make getExtraHeader return a different
idempotency-key and assert verification returns an error, then add a case where
the covered idempotency-key header is absent and represented by an empty value,
also asserting failure.
In `@client/go/verilink.go`:
- Around line 218-230: Validate idempotencyKey before any request mutation in
both Client.SignRequestWithIdempotencyKey in client/go/verilink.go:218-230 and
the corresponding Node helper in client/node/index.ts:159-170; return an error
in Go and throw in Node when the key is empty or falsy, respectively, before
setting headers or signing.
- Around line 231-257: Extract the shared signing logic from SignRequest and
SignRequestWithIdempotencyKey into a helper that accepts the request body and
optional extra components, including body restoration, targetURI construction,
timestamps, keyID formatting, and signature generation. Make both public methods
thin wrappers that supply their respective extras while preserving existing
headers and error behavior.
In `@client/node/package.json`:
- Around line 18-22: Update the build scripts and development dependencies so
tsup is declared and invoked with index.ts as the sole build emitter, while
TypeScript only performs validation via tsc --noEmit; ensure the package-lock
remains synchronized with the package.json dependency change.
- Around line 35-39: Update the client package metadata to add an engines
declaration requiring Node.js 18.19.0 or newer, matching Ed25519, --import, and
tsx loader support; do not set the general minimum to 20.6.0.
In `@client/node/test/signing.test.ts`:
- Around line 149-153: Restore the removed lookup-key error and Signature-Input
golden-vector tests in the signing test suite, porting both to TypeScript and
preserving their original assertions. Ensure the golden-vector test continues
guarding the signature-base format and the lookup-key test validates the
expected error behavior.
- Line 172: Update the request objects in the affected signing tests to use the
exported RequestLike interface, so header indexing supports Idempotency-Key,
Signature-Input, and Signature under strict typing. In the assertions around
those headers, use consistent non-null assertions before calling includes or
comparing values, covering the checks near lines 172, 245-251, and 282-283.
- Around line 199-222: Correct the test case named “verification fails without
extra header lookup” by omitting the getExtraHeader callback from
verifySignatureInput and asserting the intended verification failure. Keep the
existing successful round-trip coverage separate, and add coverage for a
tampered idempotency-key value if needed to exercise the failure path.
In `@client/node/tsconfig.json`:
- Around line 15-16: Update client/node/tsconfig.json to use a type-check
configuration that includes test/**/*.ts, and point the typecheck script to it.
In client/node/test/signing.test.ts at line 172, type the request literals as
RequestLike and use headers typed as Record<string, string> so all referenced
header accesses compile under strict checking.
In `@docs/superpowers/plans/2026-08-15-plan-12-clients.md`:
- Around line 58-64: Update the Verification section to include the mandated Go
vulnerability check and repository secret scan: add govulncheck ./... and
gitleaks detect --source . alongside the existing gates, preserving the listed
Go build/test, Node type-check, test, and build commands.
In `@pkg/requestsigin/sign.go`:
- Around line 92-101: Canonicalize extra component names to lowercase in all
signing paths: update BuildSignatureBaseWithExtra and SignWithExtra in
pkg/requestsigin/sign.go, including the covered-component list and base lines;
also update buildSignatureBase and signRequest in client/node/index.ts. Apply
the same lowercase normalization consistently before emitting or comparing
names.
- Around line 199-204: Require an extra-header resolver for every non-derived
covered component before rebuilding the signature base: in
pkg/requestsigin/sign.go lines 199-204, update the verifier to return an error
when getExtraHeader is nil instead of invoking it; in client/node/index.ts lines
226-238, return { valid: false, reason } when getExtraHeader is undefined
instead of dropping the component and reporting success. Use the existing
verifier error/result flow and preserve handling for derived components.

Add a negative test for a tampered idempotency key.
The round-trip test only proves the happy path. The stated purpose of the feature is to stop reuse of the key on another request. Add a case where getExtraHeader returns a different value and assert that VerifySignatureInputWithExtra returns an error. Also add a case where the component is covered but the header is absent (empty value).

Neither idempotency-key helper validates its key argument. The shared root cause is that both helpers accept an empty key, set an empty Idempotency-Key header, and sign an empty component value. The server then cannot distinguish "no key" from "empty key", which removes the binding the helper is meant to create.

Extract the shared signing path.
Lines 221-244 repeat SignRequest almost exactly: body read and restore, targetURI construction, created/expires, and keyID formatting. Only the extra slice differs. Two copies of the signature-base inputs will drift.

Which Node.js version added support for the --import flag with module customization hooks?
💡 Result:
The --import flag itself was added to Node.js in versions v19.0.0 and v18.18.0 [1][2][3]. While this flag can be used to preload any module, it is the recommended way to register module customization hooks before application code executes [4][5][6]. The specific mechanism for using module customization hooks—the register API in the node:module module—was stabilized and unflagged in Node.js v20.6.0 [6]. Prior to this, module customization was handled by the --experimental-loader flag, which is now deprecated in favor of using --import in conjunction with register [1][6][7]. Therefore, while the --import flag existed earlier, it became the established, non-experimental approach for initializing module customization hooks with the release of v20.6.0 [6].

tsx 4.19.0 Node.js version requirement --import module.register Node 18.18
💡 Result:
The tsx package requires a minimum of Node.js v18.0.0 [1][2]. Regarding module.register() and the --import flag: - tsx utilizes module.register() internally to enable its loader functionality [3][4]. - Support for module.register() and the --import flag was introduced in Node.js v20.6.0 [3][5]. - For versions of Node.js prior to v20.6.0 (such as v18.18.0), module.register() is not available [6][3]. Consequently, while tsx may run on these older versions, it cannot use module.register() to provide its loader functionality. - Official error messages from tsx indicate that for full module.register() support, an upgrade to at least Node.js v18.19.0 or v20.6.0 is required [7][6]. In summary, while tsx is compatible with Node.js v18.0.0 and above, the specific feature module.register()—and by extension its usage via --import for loader hooks—is only supported in later Node.js versions (v18.19.0+, v20.6.0+) [7][6][3].

This test asserts the opposite of its name.
The test is named verification fails without extra header lookup. The comment at Line 218 states "No getExtraHeader". Line 219 still passes a working getExtraHeader callback, and Line 221 asserts valid.valid === true. The test therefore duplicates the round-trip test and proves nothing about the missing-callback path.
That path is the one that currently fails open in client/node/index.ts Line 233. Change the test to omit the callback and assert the intended behavior.

The TypeScript tests are never type-checked. tsconfig.json includes only index.ts and excludes test, so npm run typecheck skips the converted test suite. That exclusion is why the untyped header accesses in the tests pass CI.

Extra component names are never canonicalized. Both signers write caller-supplied names verbatim into the signature base and the covered-component list, while both verifiers compare against lowercase derived names. A caller that passes Idempotency-Key produces a signature that a case-sensitive peer cannot verify, and the two clients can diverge from each other. RFC 9421 field names are lowercase.

🔒 Security & Privacy | 🟠 Major | ⚡ Quick win
Both verifiers mishandle an absent extra-header resolver. The shared root cause is that neither verifier requires a resolver for every non-derived covered component before it rebuilds the signature base. The component list arrives from an untrusted header, so the caller cannot know in advance which components need a lookup.
