Code Review
This pull request adds valuable unit tests for constants in the auth and cli packages. The tests are well-structured using a table-driven approach. I've provided a couple of suggestions to enhance the tests further: one to improve the robustness of comparisons in schema_test.go by using reflect.DeepEqual, and another to improve consistency in colour_test.go by matching the escape sequence format used in the source code. Overall, these are good additions to the test suite.

🧹 Nitpick comments (3)
pkg/cli/colour_test.go (2)
11-19: Nit: Align escape notation with production constants (octal vs hex).The constants in pkg/cli/colour.go use octal escapes ("\033"), while the tests use hex ("\x1b"). They’re equivalent, but mirroring the notation improves readability when diffing across files.
Apply this diff to switch to octal escapes:
- {"Reset", Reset, "\x1b[0m"}, - {"RedColour", RedColour, "\x1b[31m"}, - {"GreenColour", GreenColour, "\x1b[32m"}, - {"YellowColour", YellowColour, "\x1b[33m"}, - {"BlueColour", BlueColour, "\x1b[34m"}, - {"MagentaColour", MagentaColour, "\x1b[35m"}, - {"CyanColour", CyanColour, "\x1b[36m"}, - {"GrayColour", GrayColour, "\x1b[37m"}, - {"WhiteColour", WhiteColour, "\x1b[97m"}, + {"Reset", Reset, "\033[0m"}, + {"RedColour", RedColour, "\033[31m"}, + {"GreenColour", GreenColour, "\033[32m"}, + {"YellowColour", YellowColour, "\033[33m"}, + {"BlueColour", BlueColour, "\033[34m"}, + {"MagentaColour", MagentaColour, "\033[35m"}, + {"CyanColour", CyanColour, "\033[36m"}, + {"GrayColour", GrayColour, "\033[37m"}, + {"WhiteColour", WhiteColour, "\033[97m"},
5-6: Optional: Enable parallel execution for faster, isolated tests.Marking the top-level test and each subtest as parallel is safe here and can speed up the suite.
Apply this diff:
func TestColourConstants(t *testing.T) { - tests := []struct { + t.Parallel() + tests := []struct { name string got string want string }{ @@ - t.Run(tt.name, func(t *testing.T) { + t.Run(tt.name, func(t *testing.T) { + t.Parallel() if tt.got != tt.want { t.Errorf("%s = %q, want %q", tt.name, tt.got, tt.want) } })Also applies to: 24-28

3-6: Simplify: compare strings directly and drop reflect; also narrow typesUsing reflect.DeepEqual and any is unnecessary for string constants. Compare strings directly, make the table fields typed as string, and remove the reflect import. Optionally run subtests in parallel.

282-283: Avoid coupling tests to the insecure key choice; prefer a neutral “hmacKey”Passing seed.PublicKey as the signing key in multiple places encodes the current (insecure) behavior into tests. At minimum, name the parameter/variable hmacKey to make the coupling obvious, and plan to swap it to seed.SecretKey once middleware is fixed.
As a readability improvement, consider renaming the helper parameters to clarify semantics:
-func makeSignedRequest(t *testing.T, method, rawURL, body, account, public, signingKey string, ts time.Time, nonce, reqID string) *http.Request { +func makeSignedRequest(t *testing.T, method, rawURL, body, account, publicKey, hmacKey string, ts time.Time, nonce, reqID string) *http.Request {And update internal references accordingly (outside this hunk):
- Set X-API-Key from publicKey.
- BuildCanonical(... publicKey ...).
- CreateSignatureFrom(..., hmacKey).
When the middleware is corrected, change call sites to pass seed.SecretKey for hmacKey.

💡 Verification agent
🧩 Analysis chain
Critical: HMAC keyed with the “public” token undermines authentication semantics
These makeSignedRequest calls now sign with seed.PublicKey. If the middleware verifies HMACs using the public token, anyone who knows the public token can forge valid signatures, defeating shared-secret authentication. Tests should not ossify this behavior.
- If “PublicKey” is actually a misnamed secret, rename it for clarity.
- If it’s truly public and transmitted to the client, the verifier must derive HMAC with the secret key. Tests should sign with seed.SecretKey.
Run this script to verify what key production code uses for signature verification:
If verification confirms the public token is used for HMAC, I recommend:
- Fix middleware to verify using the decrypted secret key.
- Update these four calls to pass seed.SecretKey as the signing key.
- I can prepare the follow-up patch or open an issue with a migration/testing plan. Want me to proceed?

Fix HMAC to use the secret key, not the public token
Tests are currently ossifying an incorrect implementation: the middleware still calls
localSignature := auth.CreateSignatureFrom(canonical, token.PublicKey) //@todo Change!which means anyone with the public token can forge signatures. We must switch to token.SecretKey and update all tests that pass seed.PublicKey as the signing key.
• In pkg/middleware/token_middleware.go (around line 260):
- localSignature := auth.CreateSignatureFrom(canonical, token.PublicKey)
+ localSignature := auth.CreateSignatureFrom(canonical, token.SecretKey)• In pkg/middleware/token_middleware_test.go and pkg/middleware/token_middleware_additional_test.go:
– All calls to makeSignedRequest with … signingKey = seed.PublicKey must become … signingKey = seed.SecretKey.
(Lines 100, 115, 136, 177 in the additional test; and all occurrences in the main token_middleware_test.go.)
This restores proper HMAC semantics (shared-secret authentication) and prevents clients from forging signatures with only a public token.

pkg/middleware/token_middleware_test.go and
pkg/middleware/token_middleware_additional_test.go (notably lines 100, 115, 136,
177 in the additional test and all occurrences in the main test), the code
incorrectly uses the token.PublicKey when creating/verifying HMAC signatures;
change the middleware to call auth.CreateSignatureFrom(canonical,
token.SecretKey) (or otherwise use token.SecretKey) so HMAC uses the shared
secret, and update every test call that passes seed.PublicKey as the signingKey
to pass seed.SecretKey instead (replace the "wrong-"+seed.PublicKey test case
where appropriate) so tests sign with the secret key.

🛠️ Refactor suggestion
Doc comment normalizes an insecure behavior — annotate as TODO and clarify intent
The comment states that the HMAC is derived from the public token. If that matches production right now, it’s an insecure design and should be treated as a temporary state with a TODO.
Apply this diff to make the risk explicit and guide a future fix:
-// signingKey is the token used to create the signature. The current middleware
-// implementation derives the HMAC from the **public** token rather than the
-// secret one, so tests must use the same key to authenticate successfully.
+// signingKey is the key used to create the HMAC signature over the canonical string.
+// IMPORTANT: At the time of writing, the middleware verifies HMACs using the value
+// sent in X-API-Key (the "public" token). This is insecure because a public identifier
+// should not be used as an HMAC key. Tests currently mirror production to avoid
+// false negatives. TODO(security): switch middleware verification to the secret key,
+// then update tests to sign with the secret and remove this note.📝 Committable suggestion

Security: Signing with a public identifier is not an authentication factor
auth.CreateSignatureFrom(canonical, signingKey) will currently use a public token value in tests. Unless the “public” token is actually a shared secret (misnamed), this weakens auth. Plan to change verification to use the secret and update tests accordingly.
I can stage a change set that:
- Updates middleware to use the decrypted secret for HMAC verification.
- Switches tests to sign with seed.SecretKey.
- Adds a compatibility test to ensure old behavior is rejected.

In pkg/middleware/token_middleware_test.go around line 234, the test signs
requests using a public token value (signingKey) which is not a secret; update
tests and middleware so HMAC verification uses the decrypted secret instead.
Change the test to sign with seed.SecretKey (the actual shared secret) rather
than the public identifier, update the middleware to read and use the decrypted
secret for CreateSignature/verification, and add a compatibility test that
verifies tokens signed with the old/public value are rejected. Ensure test
fixtures and any helper functions are updated to pass the secret key and that
error messages clearly indicate rejection of legacy/public-signed tokens.
