Closes #420

Runs redactDeep over envelope.message, envelope.nextAction, and the preserved serverNextAction at the single ApiError construction point, so bearer tokens echoed in server error prose are masked in both text and JSON output. Also blanks every string member of an array stored under a secret-named key (e.g. set-cookie) instead of walking them without the secret context.

Regression tests: redact.spec.ts (array under secret key) and errors.test.ts (bearer in message/nextAction).

Summary by CodeRabbit

  • Bug Fixes
    • Sensitive information is now consistently masked in error messages and suggested next steps, including remediation text supplied by the server.
    • Sensitive values contained in lists are also masked, helping prevent them from appearing in error details.

Walkthrough

The change extends redactDeep to redact string elements in arrays under secret-matching keys. ApiError also applies deep redaction to its message and remediation strings during construction.

Changes

Error redaction

Layer / File(s) Summary
Secret-keyed array redaction
src/lib/redact.ts
redactDeep now replaces direct string elements in arrays under secret-matching keys. It recursively processes other array elements.
ApiError text redaction
src/lib/errors.ts
ApiError now applies redactDeep to its message, nextAction, and serverNextAction.

Echoed alphabetic-only bearer tokens may remain visible in CLI error text and JSON. This is a narrow but real gap in the intended redaction; account for it before relying on the protection.

Explanation

The implementation meets the behavior in [#420]. ApiError redacts message, effective nextAction, and serverNextAction. redactDeep replaces direct string members in arrays under secret keys. The whole-PR diff contains no changes to src/lib/errors.test.ts or src/lib/redact.spec.ts, so the linked issue's requested regression tests are not included.

Resolution

Add automated tests in src/lib/errors.test.ts for bearer tokens in message, nextAction, and JSON/text error output. Add an automated test in src/lib/redact.spec.ts for string members of an array under a secret key such as set-cookie.

Handle alphabetic bearer tokens without broadening prose matches.

BEARER_TOKEN_RE rejects Bearer abcdefgh because its lookahead requires a digit. The value can therefore remain in ApiError.message, nextAction, and serverNextAction, which violates the error-prose redaction requirement.

Removing the digit lookahead alone is not safe. It would also redact prose such as Bearer authentication and Bearer token-based, which existing tests require to remain unchanged. Update the matcher and regression tests so letter-only bearer tokens are redacted while these prose cases remain excluded. Retaining only the current token-character checks does not provide that distinction.

Thanks @Lexiie. Closing along with #420, which we're not taking (our API's error messages never echo the request's credentials).
