FILTERS:
    Filter may be an RFC status, phase, or ID/title substring.

    govctl rfc list draft
    govctl rfc list impl -n 5
    govctl rfc list RFC-0002 -o json

VALID FIELDS:
    - title, version, status, phase, owners, refs

EXAMPLES:
    govctl rfc get RFC-0001
    govctl rfc get RFC-0001 title
    govctl rfc get RFC-0001 refs
")]
    Get(CommonGetArgs),
    /// Show rendered RFC content
    #[command(after_help = "\
EXAMPLES:
    govctl rfc show RFC-0001
    govctl rfc show RFC-0001 -o plain

NOTES:
    - `show` prints human-readable rendered content.
    - Use `get` for field/path-level inspection.
")]
    Show(CommonShowArgs),

EXAMPLES:
    govctl rfc new \"Add incremental index rebuilding\"
    govctl rfc new \"Add incremental index rebuilding\" --id RFC-0010

NOTES:
    - Use `--id` only when you need to pin a specific RFC ID.
    - New RFCs start as draft and can later be finalized.

VALID FIELDS:
  String fields (use 'set'):

  Array fields (use 'add' / 'remove'):
    - owners, refs, sections

EXAMPLES:
    govctl rfc set RFC-0001 title \"New Title\"

Use dedicated lifecycle verbs instead of `set` for:
    - version → `govctl rfc bump`
    - status → `govctl rfc finalize` / `govctl rfc deprecate` / `govctl rfc supersede`
    - phase → `govctl rfc advance`

VALID ARRAY FIELDS:
    - refs: Cross-references to other RFCs (e.g., \"RFC-0002\")
    - owners: RFC owners (e.g., \"@alice\")

EXAMPLES:
    govctl rfc add RFC-0001 refs RFC-0002
    govctl rfc add RFC-0001 owners @alice
")]
    Add(CommonAddArgs),

VALID ARRAY FIELDS:

MATCHING OPTIONS:
    - pattern: Substring match (default)
    - --at N: Remove by index (0-based, negative = from end)
    - --exact: Exact string match
    - --regex: Regex pattern match
    - --all: Remove all matches

EXAMPLES:
    govctl rfc remove RFC-0001 refs RFC-0002     # Remove first match
    govctl rfc remove RFC-0001 refs --at 1       # Remove by index
")]
    Remove(CommonRemoveArgs),
    /// Bump RFC version
    #[command(after_help = "\
EXAMPLES:
    govctl rfc bump RFC-0001 --patch -m \"Clarify examples\"
    govctl rfc bump RFC-0001 --minor -c \"changed: New normative clause\"

NOTES:
    - Exactly one of `--patch`, `--minor`, or `--major` must be chosen.
    - Use `-m/--summary` for a release summary and `-c/--change` for detailed entries.

EXAMPLES:
    govctl rfc finalize RFC-0001 normative
    govctl rfc finalize RFC-0001 deprecated

NOTES:
    - Finalize is used once the RFC leaves draft state.
    - Use `advance` to move phase after finalization.

EXAMPLES:
    govctl rfc advance RFC-0001 impl
    govctl rfc advance RFC-0001 test

NOTES:
    - Typical progression is `spec -> impl -> test -> stable`.
    - Use this after the RFC has been finalized.
