  1. scep.BadRequest is a FailInfo constant with value "2"
  2. scep.BadRequest.String() returns "badRequest (2)"
  3. scep.BadRequest is distinct from other FailInfo constants
  4. CertRepMessage can be constructed with scep.BadRequest failInfo
  5. PKIMessage.Fail with scep.BadRequest produces a CertRep failure message containing scep.BadRequest

Clean-room public code sample — generation instructions

Write a brand-new, minimal, self-contained code sample in this clean-room directory.
Do not copy, paraphrase, or reference any existing project source. Work only from this spec.

A csx.json manifest scaffold already exists. Do not recreate it from memory. Preserve its case.goal, packages and symbols; fill its empty case.contract with exact assertions and correct its environment, commands and verifierAdapter for the files you generate.

Goal: verify github.com/smallstep/scep.BadRequest in pkg:golang/github.com/smallstep/scep@v0.0.0-20231024192529-aee96d7ad34d
Kind: HOW

Use EXACTLY these public packages and versions:
  - pkg:golang/github.com/smallstep/scep@v0.0.0-20231024192529-aee96d7ad34d
Demonstrate these symbols/APIs:
  - github.com/smallstep/scep.BadRequest
Constraints:
  - executionContext: node
Required runtime conditions:
  - ecosystem: npm
  - language: javascript
  - moduleSystem: esm
  - packageManager: npm@10.9.8
  - runtime: node@22.23.2

Rules:
  - One focused purpose; the smallest project that proves the goal.
  - Include a contract test (test/contract.*) that runs OFFLINE and exits 0 exactly when the goal behavior works.
  - Pin every dependency with a lockfile so resolution is reproducible.
  - No secrets, credentials, or tokens. No real URLs (only example.com or localhost). No absolute paths.
  - No personal names, emails, company names, or project identifiers of any kind.
  - No binaries and no generated output (node_modules, dist, target, venv, .git, .env).
  - Keep it under 200 files and 256KB packed.
