Fix all 8 findings from the independent review (FIXME_M10.md):
#1 Transport compatible with slixmpp 1.17.0 (D5):
- Use real ClientXMPP type (remove Any), JID with resource
- connect(host, port) explicit, no use_tls kwarg
- enable_direct_tls/enable_starttls configured before connect
- Single timeout via asyncio.Future for session_start/failed_auth/disconnected
- Remove premature 'starttls' in features check, remove auto_reconnect
- try/finally guarantees disconnect on all paths (#4)
#2 Factory dry_run no longer bypassed (D6):
- Single send() entry point in SyncXmppChannel
- dry_run check before any ClientXMPP creation
- Remove XmppChannel.send() dual implementation
#3 Thread daemon removed — single asyncio.run(), documented limitation
#5 Richer message format:
- Target date header, change type [Ajouté/Supprimé/Modifié]
- Lesson times, homework due date, message author
- No pronote_messages duplication (external_info = blog + other_info only)
#6 Error contract unified (D6):
- Channel.send() -> bool never raises PipelineWarning
- Errors logged with redaction, returns False
- PipelineWarning(step='xmpp') will be created by pipeline M11
#7 Tests faithful to slixmpp 1.17.0 API:
- FakeClientXMPP with real connect(host,port)/disconnect() signatures
- Assertions on host, port, resource, mtype='chat'
- No RuntimeWarning from unawaited coroutines
#8 .secrets.baseline restored from main
Coverage: 96.44% on channels/, 600 tests pass, pre-commit all-files green.
