Channels: 'not currently available' on Max account (tengu_harbor not enabled)

Problem

Running claude --channels plugin:telegram@claude-plugins-official produces:

--channels ignored (plugin:telegram@claude-plugins-official)
  Channels are not currently available

Setup

• Claude Code v2.1.91 (latest)
• macOS arm64
• Bun 1.3.11 installed
• Telegram plugin installed via /plugin install telegram@claude-plugins-official
• Authenticated via claude.ai OAuth (Max subscription, not Team/Enterprise)
• Token configured in ~/.claude/channels/telegram/.env

Root cause

The binary gates channels behind the tengu_harbor feature flag, which is not enabled for my account. The flag defaults to false, so channels are blocked before any org or auth check runs.

Expected behavior

Per the channels docs: "Pro and Max users without an organization skip these checks entirely: channels are available and users opt in per session with --channels."

I'm a Max user. Channels should be available.

Request

Please enable the tengu_harbor feature flag for my account, or clarify the timeline for the broader rollout.
