A second `tunnel start` or process using the same credential takes over, and the first exits **10**.
An environment is one origin (scheme, host and port) plus its sign-in configuration. Frontend runs automatically open a tunnel for a saved `localhost`, `127.0.0.1` or `[::1]` URL: `test run`, `test rerun`, `test create --run`, `test create-batch --run` and `testlist run` use this behavior. `--env <name>` selects the environment; omit it for the project default. `--no-wait` disables automatic tunnels; drop it to run through one. If environment reads are unavailable, the command keeps the previous server behavior. Several fresh-run IDs require a tunnel; public targets retain the exit-5 refusal. A named public environment used against a local origin prints a sign-in advisory on stderr. Reruns and test-list runs share one timeout including capacity waits and require the server to confirm tunnel support; an older server triggers a cancellation attempt and a clear error.

`--local <port>` remains a shorthand and defaults new project/environment URLs to `http://localhost:<port>`. On a test run it preserves the host of a selected loopback environment, or the one host agreed by saved non-temporary loopback environments on that port; otherwise it uses `localhost`. If environment reads fail, it retains the legacy `127.0.0.1` host. Saved URLs retain their exact spelling, and aliases are not merged. `--local-host` remains accepted but is deprecated and hidden from project/environment help; prefer `--url http://127.0.0.1:<port>` or `--url http://[::1]:<port>` when the host matters. Dev servers can take a minute per page through a tunnel; test a built server with `npm run build` and your framework's preview/start command for heavy apps.
The control plane is WebSocket over TLS (`wss://control.tun.testsprite.com/ws`). The data plane, which carries the tunnel secret and proxied traffic, uses TLS at `data.tun.testsprite.com:443` and verifies the certificate with Node's default trust store: its bundled Mozilla roots, plus certificates supplied through `NODE_EXTRA_CA_CERTS` and the system CAs when Node is started with `--use-system-ca`. Node 20 is supported without losing `NODE_EXTRA_CA_CERTS`. Verification cannot be disabled, and the CLI never falls back from TLS to plaintext. On a network that re-signs TLS, export your organisation's root CA to a PEM file and set `NODE_EXTRA_CA_CERTS=/path/to/ca.pem` before running `testsprite`. Plaintext connects and TLS handshakes each time out after 10 seconds. The first failed attempt starts a **60-second** retry episode; writing `TunnelHello` is not enough to reset it. The episode ends only after the first inbound tunnel stream or after the socket remains open for 5 seconds following the hello. A real deadline timer stays armed across retries and destroys an in-flight socket when it expires. After that, an owned `test run --local` run is cancelled and refunded and the command exits **10**; `tunnel start` exits **10**. If a self-hosted or older TestSprite server does not advertise a TLS endpoint, the CLI prints a one-time warning and uses legacy plaintext port **7400** under the same timeout and retry rules. `tunnel start` prints `transport: tls` or `transport: plaintext`.
An owned tunnel's timeout or Ctrl-C cancels unfinished runs by default. A borrowed run still detaches without cancellation on Ctrl-C/SIGTERM because its owner keeps the tunnel alive; if that owner disappears while a run is active, the borrower cancels its own run and reports `cancelled`, `already finished`, or `skipped`. A run cancelled before it finishes is refunded. `--no-cancel-on-interrupt` also skips this owner-gone cancellation. Keep the early stderr run-id receipts (`Run <runId>` for one test, `[i/N] <testId> → run <runId>` for a batch) and read the reported runs before re-running.
Local projects skip exploration/plan generation; author plans with `test create --plan-from`. Portal runs are blocked for free until you set a public project URL.
See [the full local-testing reference](./DOCUMENTATION.md#local-frontend-testing-and-tunnels) for flags, login, billing/refunds, timeouts, and retargeting.
`--local <port>` saves new project and environment URLs as `http://localhost:<port>`. Use `--url http://127.0.0.1:<port>` or `--url http://[::1]:<port>` when the host matters (`--local-host` is deprecated). Dev servers can be slow through a tunnel, so for heavy apps test a production build (`npm run build` plus your framework's preview or start command).

State that localhost is the default.

--local-host remains accepted and overrides the host saved by --local <port>. Describe localhost as the default, or state that --local-host remains an override.

Suggested wording 
-`--local <port>` saves new project and environment URLs as `http://localhost:<port>`.
+`--local <port>` defaults new project and environment URLs to `http://localhost:<port>`. Use `--local-host` to override the host.

Review comment at @README.md at line 157:
Update the README description of `--local <port>` to state that `localhost` is
the default and that `--local-host` remains available to override the saved
host; retain the existing guidance about explicit `--url` values.

The tunnel uses verified TLS. On a network that re-signs TLS, set `NODE_EXTRA_CA_CERTS=/path/to/ca.pem` to your organisation's root CA. If the tunnel keeps failing to connect for 60 seconds, the command exits **10**, and an owned run is cancelled and refunded.

Qualify the TLS guarantee.

Older or self-hosted servers that do not advertise a TLS endpoint use the legacy plaintext data port. Update this sentence so it does not imply that every supported tunnel connection is encrypted.

Suggested wording 
-The tunnel uses verified TLS.
+The tunnel uses verified TLS when the server advertises a TLS endpoint. Older or self-hosted servers without one use the legacy plaintext data port.

Update the README sentence to qualify that tunnels use verified TLS when the

use the legacy plaintext data port. Keep the existing CA guidance and timeout

On an owned tunnel, Ctrl-C or a timeout cancels unfinished runs by default, and a run cancelled before it finishes is refunded. A run on a borrowed `--tunnel-client` detaches on Ctrl-C instead. Local projects skip plan generation, so write plans with `test create --plan-from`. Portal runs stay blocked, at no charge, until the project has a public URL. See [the local-testing reference](./DOCUMENTATION.md#local-frontend-testing-and-tunnels) for the details.
