Summary

Covers Domain 9 (Device Pairing) of shellhub-io/team#243. Stacked on #7360 for its order in the
stack only; it builds on the helpers from #7353.

└── device-pairing.spec.ts         the console switches to a device's namespace before accepting it

The agent tests start an agent with no tenant. They read its pairing code from the log, accept it
as the owner, and check the agent connects without a restart and keeps the tenant in its
.tenant file. Expiry lowers the cache entry's TTL to five seconds and waits for the cache to
drop it. Each expiry test first checks the code still answers, so the 404 afterwards comes from
expiry.

The four [both] items get testcontainers tests only. The API layer asserts each claim, and all
that is left for the UI is rendering, which the issue leaves to Vitest with MSW. The
namespace-switch spec skips community, like the other namespace-switching specs, so it runs in the
enterprise and cloud e2e jobs.

Evidence

• Before: none of the 15 Domain 9 items had a test.
  After: go test ./... in tests/ passes (1234s), and so do the focused runs after review:

  --- PASS: TestDevicePairing        pairing (3), login_code (5), code_format (2), device_limit (1)
  --- PASS: TestDevicePairingAgent   starts and waits, learns by polling, keeps its tenant
  --- PASS: TestEnrollmentPolicy/limits
  

• Each test was seen failing against a broken server, rebuilt into the test stack:

  Server change	Test that failed
  skip the pending-code lookup by public key	pairing/pairing again with the same public key returns the pending code
  pairingcode.Normalize returns its input	code format/a code is read without its hyphen and in any case
  keep the previous login code	login code/a new code invalidates the one before it
  skip validateDeviceAcceptance	device limit/a namespace at its device limit refuses a pairing until the limit is lifted
  pairingcode.IsValid accepts any 8 characters	code format/a code with a character outside the alphabet is not found, even when the cache holds it
  AcceptDeviceFlow never switches namespace	accepting a device by its login code › the console switches to the namespace of a device in another one

• The Playwright spec was run on community with its skip lifted, since this checkout holds no
  enterprise license: it passes, and fails with the switch disabled.

Merge Danger

Door: two-way

Tests only. The one stack change: every testcontainers stack now registers the redis service,
which all editions' compose files already run.

Blast Radius: tests

A refused accept at the device limit still leaves a pending device with the pairing's hostname in
the namespace. If someone later accepts that device from the device list, the agent never learns
it was accepted: the pairing status stays pending. The tests leave that unasserted; the fix
belongs in the server.

Code Review Complete

Reviewed 10 files and posted 3 inline comments, all Standards judgement calls. There are no rule violations and no Correctness issues. The Spec axis did not run.

Standards

The worst of the three is the "no device has this hostname" loop, written out four times. The first copy is at tests/device_pairing_test.go:60-62. A deviceNames helper used with assert.NotContains, the way tests/device_lifecycle_test.go already uses deviceUIDs, would replace all four. The other two comments:

• pairAgent in tests/member_test.go still builds its own accept request, the same one postPairingAccept now sends.
• The tests type the server's cache keys (pairing_code/, login_code/) by hand at four call sites.

Spec

The Spec axis did not run. The PR names only shellhub-io/team#243, which is in another repository this run cannot read, and it closes no issue in this repo.

Additional notes

• I checked that the cache key formats and TTLs match the server, and that the outside-alphabet and device-limit tests would fail if the server check they cover were removed.
• Every poll in the tests has a deadline, contexts propagate through t.Context(), and the redis service the stack now requires is defined in the base compose file.
• No judgement calls were dropped by the cap.

Code Review Complete

Reviewed 11 files on two axes: Standards (repo rules, language conventions, tests, code smells) and Correctness (security and runtime defects). No new issues found. The code looks good as-is.

The Spec axis did not run. The PR cites only shellhub-io/team#243, which is in a repository this run cannot read, and no commit carries a Fixes: trailer.
