Thanks for pushing this through. Overall direction looks good: IRC is wired into shared channel surfaces (registry/dock/config/schema), plugin packaging looks sane, and you added a solid set of focused tests + docs.

Requests before merge

• Config schema parity: please double-check IRC allowlist fields are consistently typed as Array<string | number> everywhere (core zod schema, any plugin schema, and runtime normalization). Today dock.ts coerces entries to String(...), and docs/examples use strings, so a mixed-type config should not fail validation in one place but pass in another.
• Duplicate group matching logic: core now supports case-insensitive groupId matching via src/config/group-policy.ts (used by IRC dock tool/mention policy resolution), while the IRC extension also does its own case-insensitive matching in extensions/irc/src/policy.ts. Please either unify on one canonical resolver or add a small parity test so inbound enforcement stays aligned with shared surfaces (status/config UX/tool policy resolution).

Optional follow-ups (can be post-merge if you prefer)

• In docs/channels/irc.md, consider explicitly stating that IRC config lives under channels.irc (not plugin config), since this is an extension but behaves like a first-class channel in core surfaces.

Addressed all three points from your review in f2c2e63:

1. Config schema parity for IRC allowlists

• Extension IRC schema now accepts Array<string | number> for:
  • allowFrom
  • groupAllowFrom
  • groups[...].allowFrom
• Extension IRC types were updated to match.
• Added tests for numeric/mixed allowlist entries in:
  • extensions/irc/src/config-schema.test.ts
  • src/config/config.irc.test.ts

2. Group matching parity with shared resolver

• Added a parity test in extensions/irc/src/policy.test.ts that compares IRC inbound matching behavior against resolveChannelGroupPolicy(..., groupIdCaseInsensitive: true) for case-insensitive direct and disabled channel cases.

3. Docs clarification

• Added explicit note to docs/channels/irc.md that IRC ships as an extension plugin but is configured under channels.irc.
