The operator console over stdio, and the registry it is now listed in - #51
Conversation
Pairs with the kernel branch of the same name, which adds `ctrlrun mcp-operator --stdio`. The approve-from-your-assistant page now opens with the case that needs no proxy: the person answering is at the keyboard, the desktop assistant or editor launches the server itself, and the config block is the one a client installs from the registry. The HTTP-behind-a-proxy mode follows as its own section, with its "no flag changes that" sentence amended, since `--stdio` binds nothing at all. What the server will not do gains the line the design turns on: it takes no name from the client that launched it. The overview's registry paragraph said the entry was a launch-day item and that the gateway would be the thing listed. Both were wrong by the time anyone read it: the listing went live at 0.12.2 and what is listed is the operator server, the gateway being a proxy no registry can point a client at. Rewritten with the two live links. `docs/reference/cli.mdx` regenerated for the new flag. Every audit step green. Signed-off-by: arpan <contact@arpanghoshal.com>
The page claimed the client could not choose the approver's name. The uid it cannot choose; the name the process reports is only as trustworthy as the process, and what makes the design sound is that such a client could already open the store as that account. The page now says that, and the two consequences a person should know before relying on it: the login has no expiry, so the client's own confirmation is the human step; and root is an account, not a person, so writes refuse under it. CLI reference regenerated for the reworded flag. Signed-off-by: arpan <contact@arpanghoshal.com>

State the registry availability version.
This section does not state that the registry listing became available in version 0.12.2. Add that version boundary so users can determine whether their installed release supports registry installation.
As per PR objectives: the registry listing must state that it became available in version 0.12.2.

Distinguish HTTP and stdio write identities.
The preceding write-tool bullet says every write requires a credential from a configured identity provider. These lines state that stdio writes use the process account OS login. Update the bullet to describe an attributable human identity, with an identity provider for HTTP and OS-login attribution for stdio.

Pairs with CTRLRun/ctrlrun#228, same branch name, so each CI checks the other. Merge right after it.
Approve from your assistant now opens with the case that needs no proxy: the person answering is at the keyboard, the desktop assistant or editor launches the server itself, and the config block is the one a client installs from the registry (
uvx ctrlrun mcp-operator --stdiowithCTRLRUN_CONFIG). It says what the login does and does not promise, after the independent review corrected an overclaim in the first draft: the account the process runs as, read from the real uid; a client that could forge the name could already open the store as that account. And the two things to know before relying on it: the login has no expiry, so the client's own confirmation before a write is the human step; root is an account and not a person, so writes refuse under it. The HTTP-behind-a-proxy mode follows as its own section, its no flag changes that sentence amended since--stdiobinds nothing at all.The overview's registry paragraph said the entry was a launch-day item and that the gateway would be the thing listed. Both were wrong by the time anyone read it: the listing went live at 0.12.2, and what is listed is the operator server, the gateway being a proxy no registry can point a client at.
