# Quality gates: the CLI

Criteria beyond the automatic tests (`cbd-cli`, `crabidy-server`, `cbd-tui`).
Each gate is pass/fail by reading the code. See `architecture/cli.md`. Boxes are
checked as the implement stage verifies them; deviations noted inline.

## Parsing and defaults

- [x] Every binary (`crabidy-server`, `cbd-tui`, `cbd`) parses with clap-derive;
  `--help`, `--version`, and per-subcommand `--help` work.
- [x] **No subcommand preserves today's behavior**: `crabidy-server` runs the
  server, `cbd-tui` runs the TUI, `cbd` runs the in-process server + TUI. No
  extra output, no behavior change on the default path.
- [x] The client config still writes a defaults file on first run, and a
  provided `--address/--user/--password/--spectrum` overrides the file value;
  omitted flags fall back to the file. The `cbd-tui.toml`/`cbd.toml` schema is
  unchanged (same keys).

## `guard` (server)

- [x] Prints the argon2id PHC hash to stdout and nothing else on the hash line
  (pipe-friendly); the password is never logged.
- [x] Without `--no-config`, writes the hash into the correct `[auth]` field
  (`owner`/`queue_owner`/`queue_appender`) of `crabidy-server.toml`, creating the
  file if missing and **preserving the other roles** and the flat shape
  (`deny_unknown_fields` still parses the result).
- [x] `--no-config` only prints (the exact replacement for the old
  `hash-password`).
- [x] A missing password argument reads one line from stdin.

## `scan` (server)

- [x] Walks the path (bounded, skips hidden), selects files by audio extension,
  and writes a `<stem>.cbd-track.toml` beside each with a `Playable::File`
  pointing at the file's own name; an existing toml is left untouched (warned).
- [x] `--capture` ingests each file into the content store (hash + de-dup +
  sidecar) and writes a `Playable::Store` toml instead; re-scanning de-dups.
- [x] `--move` moves the source into the store instead of copying; the original
  location keeps only the toml. `--capture`/`--move` require a store dir.
- [x] No panic on unreadable files/dirs; each defect is a warning, the walk
  continues.

## `auth` (client)

- [x] Writes `user` (role name) and `password` (cleartext), and `address` when
  given, into the client config, preserving other fields; creates the file if
  missing. The help text says the password is stored in plaintext.

## `library` / `queue` / `global` (remote)

- [x] Each subcommand maps to the documented RPC (including a new `Stop`
  wrapper); `library list` prints child nodes and tracks (captured rows marked).
- [x] Connects with basic-auth from `--user/--password` (config fallback); an
  empty user talks to an open server with no header.
- [x] A server/RPC error exits non-zero with a readable message; no internal
  report (color-eyre chain) is dumped for an ordinary "server unreachable" or a
  gRPC status — those map to a concise message.
- [x] The commands are available on `crabidy-server`, `cbd-tui`, and `cbd`
  (cbd = union of server + client commands).

## Assets

- [x] `clap_complete` + `clap_mangen` generate bash/zsh/fish completions and a
  man page for each binary from its top-level `Command` in `build.rs`
  (`OUT_DIR`), and into `$CBD_ASSET_DIR` when set.
- [x] `build.rs` build-depends on `cbd-cli` with **default features only** (no
  tonic on ordinary builds).
- [x] A `completions <shell>` subcommand prints a script to stdout.
- [x] A devenv `gen-cli-assets` script produces `dist/completions/**` and
  `dist/man/*.1`.

## Errors and safety

- [x] Library errors are `thiserror`; CLI reports use `color-eyre`; no panics on
  bad input, missing config, or an unreachable server.
  _(Deviation: CLI reports use `Box<dyn Error>`, matching the existing
  binaries' convention, not `color-eyre` — see plan/summary.md.)_
- [x] Passwords never appear in logs or error messages; the argv-exposure of a
  password argument is documented and a stdin path is offered.
