The gates `tengu_harbor_kite`, `tengu_harbor_kite_win` and `tengu_harbor_kite_mode_emit` all fall back to true in this build. The cloud variant stays off: `tengu_harbor_kite_cloud` falls back to false unless `CLAUDE_CODE_HARBOR_KITE_CLOUD` is set.\n\n**Details**\n\n- Previously these fell back to off, so the feature was dark without an explicit server value.\n- Mode emission (reporting which messaging mode a session is in) is covered by the same default flip.\n\n**Evidence**\n\n`tengu_harbor_kite_mode_emit`\n\n- Flag `tengu_harbor_kite`: On for this account, and not off by default (read for one account on one subscription tier against v2.1.248; this account: on, anonymous baseline: on, compiled default: on)\n- Flag `tengu_harbor_kite_win`: On for this account, and not off by default (read for one account on one subscription tier against v2.1.248; this account: on, anonymous baseline: on, compiled default: on)\n- Flag `tengu_harbor_kite_mode_emit`: On for this account, and not off by default (read for one account on one subscription tier against v2.1.248; this account: on, anonymous baseline: on, compiled default: on)\n- Flag `tengu_harbor_kite_cloud`: Off in both readings (read for one account on one subscription tier against v2.1.248; this account: off, anonymous baseline: off, compiled default: off)\n- Area: Cross-Session Messaging\n- Names: `CLAUDE_CODE_HARBOR_KITE_CLOUD`\n- Tier: You'll notice\n- Useful: 4\/5\n- Signal: 4\/5"}
