# M4b task 03: `bxctl deny`, another name for `refuse`

**Branch:** `m4b` (run `git switch m4b`; `git status --short` must be empty, otherwise stop)
**Commit subject:** `bxctl: deny, another name for refuse`

## Goal

In Mattermost the owner answers `!deny <id>`; in the terminal the word should work too. `bxctl
deny` means exactly what `bxctl refuse` means, argument for argument, errors included.

## Files

- Copy: `crates/bxctl/tests/cli_deny.rs`
- Modify: `crates/bxctl/src/cli.rs`, `docs/implementer-log.md`

## The changes, exactly

In `crates/bxctl/src/cli.rs`:

1. In `parse`, `"refuse" => parse_refuse(rest, home),` becomes
   `"refuse" | "deny" => parse_refuse(rest, home),`.
2. In `USAGE`, after the two lines about `bxctl refuse`, add a blank line and:

```text
  bxctl deny <id> [--reason TEXT] [--admin-socket PATH]
      Another name for refuse.
```

(keep the two-space and six-space indents of the lines around it).

## Steps

- [ ] **1. Copy.** `git switch m4b`, then `cp docs/plans/M4b/files/crates/bxctl/tests/cli_deny.rs crates/bxctl/tests/`
- [ ] **2. See it fail.** `cargo test -p bxctl --test cli_deny`. Expected: 2 fail.
- [ ] **3. Make the two changes.**
- [ ] **4. See it pass.** `cargo test -p bxctl`. Expected: every suite passes; `cli_deny` 2 passed.
- [ ] **5. Run the gate.** `cargo fmt --all`, then `make gate`. Expected last line: `gate: ok`.
- [ ] **6. Log and commit.** `git add crates/bxctl docs/implementer-log.md Cargo.lock && git commit`

## Done when

- `cargo test -p bxctl` passes; `make gate` prints `gate: ok`.
