Enum ChannelId 

pub enum ChannelId {
    IMessage,
    Slack,
}

The closed set of approval channels. Exhaustively matched everywhere — no _ => wildcard (CLAUDE.md rule #2), so a future channel forces every match site to be revisited rather than silently swallowed.

Serialized as a stable lowercase string ("imessage" / "slack") so it is a deterministic BTreeMap key on disk (Unit 2) and a back-compat wire token (Unit 6 adds the optional channel request field, defaulting to IMessage). Ord is derived for the BTreeMap key ordering, giving messaging.json a deterministic channel order regardless of insert order.

Variants

IMessage

Apple iMessage — the FIRST adapter (#403’s transport, re-homed). The back-compat default for the WS surface.

Slack

Slack — Socket Mode inbound + Web API + Block Kit buttons (Unit 4). The maximally-different second channel that proves the seam holds.

Implementations

impl ChannelId

pub const ALL: [ChannelId; 2]

Every channel, in Ord order. The cross-platform boot/registry iterates this to spawn each enabled adapter (Unit 3). Exhaustive by construction — adding a variant means adding it here.

pub fn as_str(self) -> &'static str

The stable string key (matches the serde rename). Exhaustive match — no wildcard.

pub fn from_str_opt(s: &str) -> Option<ChannelId>

Parse the stable string key back to a ChannelId. The WS surface uses this to map the optional channel request field (Unit 6); an absent field defaults to IMessage at the call site, not here.
