Drop autogroup/localpart strictness on SSH users. Drop checkPeriod minimum. Reject empty/wildcard users and empty acceptEnv at parse. Match SaaS wording for action and checkPeriod errors. 28 captures under testdata/ssh_results/ssh-malformed-*.hujson lock the surface.

// Compatibility tests for the policy `sshTests` block, replaying captures
|
|
// recorded against a real Tailscale SaaS tailnet. The runner mirrors the
|
|
// pattern in policytester_compat_test.go: a single Glob over a testdata
|
|
// directory, one t.Run per file. Each capture is one of:
|
|
//
|
|
// - APIResponseCode != 200 — the policy was rejected by SaaS, the
|
|
// captured Message is the body the user saw, and headscale must
|
|
// reject the same input with an error string that contains the same
|
|
// body (substring match, allowing wrapping like "test(s) failed:\n…").
|
|
// - APIResponseCode == 200 — SaaS accepted the policy (its sshTests
|
|
// block passed); headscale's evaluateSSHTests must also pass.
|
|
//
|
|
// Captures live in testdata/sshtest_results/*.hujson. Scenarios in
|
|
// knownSSHTesterDivergences are skipped with their tracking note —
|
|
// these are real Tailscale ↔ headscale divergences that need engine-level
|
|
// fixes in follow-up PRs.
