+`os environments list | show | create | bind | switch` run on the `os cloud login` session
+
+Clause-②: yes (widening)
+
+The documented hosted flow is `os cloud login`, then `os environments create`. The five
+`os environments` subcommands read only `~/.objectstack/credentials.json` (the `os login`
+session), so with only `~/.objectstack/cloud.json` they exited 1 with
+`Authentication required` before sending any request, while `os login --help` sends hosted
+users to `os cloud login`.
+
+All five now choose their session in one shared resolver:
+
+- With no `--url` / `OS_CLOUD_URL`, they use the `os login` session when there is one, which
+  is the same behaviour as before. Otherwise they use the `os cloud login` session and the URL
+  it recorded.
+- With a `--url`, they use the session whose file names that server, `credentials.json` first.
+  When neither file names it, they use `credentials.json`'s session as before. The cloud token
+  is never sent to a URL other than its own.
+- The active environment sent with each request comes from the chosen session's file.
+  `os environments switch` and `create --activate` no longer write a cloud environment id into
+  `credentials.json` when they ran on the cloud session.
+
+With no session at all, the `Authentication required` message now names `os cloud login` as
+well as `os login`. `os package publish` is unchanged: it still reads only `cloud.json`.

-`os environments create` does not use the session `os cloud login` stored: give
-it `--url` and `--token` (or `OS_CLOUD_URL` / `OS_TOKEN`), or an `os login`
-session. Without either it exits 1 with `Authentication required`.
+`os environments` runs on either stored session. With no `--url` it talks to
+the server of the `os login` session (`credentials.json`) when there is one,
+else to the server of the `os cloud login` session (`cloud.json`), with that
+session's token. A `--url` (or `OS_CLOUD_URL`) picks the session that names
+that server, `credentials.json`'s first — so with both stored, a `--url` naming
+the cloud uses the cloud session. A `--url` neither file names gets
+`credentials.json`'s token as before, never `cloud.json`'s. With no session and
+no `--token` / `OS_TOKEN`, it exits 1 with `Authentication required`.
