  Summary: Synapse Twisted → asyncio Migration

  What's been built (Phases 0-7) — 10 new files, ~3200 lines, 96 tests

  Every Twisted component has an asyncio-native replacement ready:

  What's been wired in safely — 224 files changed, 0 regressions

  - MemoryReactor type hint → Any across 198 test files (cosmetic)
  - synapse/http/server.py — catches both Twisted and asyncio CancelledError
  - All 4530 tests still pass (minus the 2 pre-existing failures)

  What remains for the flag day

  The actual switchover requires rewriting 5 core files simultaneously, then running a migration script across ~500 files:

  1. tests/unittest.py + tests/server.py — switch from twisted.trial.TestCase to unittest.TestCase, MemoryReactorClock to FakeAsyncioLoop, get_success() to asyncio run_until_complete()
  2. synapse/logging/context.py — switch current_context() to ContextVar, make_deferred_yieldable() to async, run_in_background() to create_task()
  3. synapse/util/async_helpers.py — rename Native* classes to canonical names, remove Deferred-based originals
  4. Migration script — update all CancelledError, defer.*, Deferred imports across ~500 files
  5. pyproject.toml — remove Twisted dependency

  This is an atomic change because: ContextVar can't coexist with Twisted's reactor callbacks, make_deferred_yieldable's signature change breaks all callers, and CancelledError is a different
  class between Twisted and asyncio.
