Land-ready review completed.

Evidence:

• fresh full codebase-memory graph: 274,060 nodes / 1,095,975 edges across 20,762 files
• current CI dead-code report plus whole-repository exact-symbol and public-barrel audit
• node scripts/run-vitest.mjs over 20 Telegram test files: 648 tests passed
• Blacksmith Testbox tbx_01kwvzgmnwzvj0vfw4wavpv7wm: pnpm check:changed passed, including core/extension production and test typechecks, full core/UI/packages/extensions lint, storage/sidecar guards, and zero runtime import cycles
• two fresh Codex autoreview runs: no actionable findings, confidence 0.86
• structural assertion confirmed all 49 semantic changes only remove export
• git diff --check passed

Known proof gaps: none for this behavior-neutral export-surface refactor. No live Telegram lane is required because transport, delivery, authorization, callbacks, streaming, and runtime behavior are unchanged.

Merged via squash.
