Two traps this hit, both invisible to a line count:
- _FakePersistence is declared *after* main(), so a naive cut at the last
brace dropped it; sync_revisions_persistence_test.dart failed to load
until it was carried across. Audited every other split file for trailing
top-level declarations — this was the only one.
- Copying the preamble into each sibling left helpers the sibling never
uses. `dart analyze` flagged 12; all removed rather than left as dead
code, and the analyzer is now clean.
crdt_sync_dart 280 passed, sync_settings_ui 29 passed, github_device_auth
analyze clean — all matching a clean HEAD worktree.

Groundwork for moving diet-guard, screen-locker and wake-alarm off fixed
role ids ('pc'/'phone'/'desktop') onto per-install uuids, the scheme todo
and home_inventory already use. A role constant collides the moment a
second machine takes the same role, and a reinstall silently inherits the
previous install's CRDT identity.
The migration cannot rewrite history: the device id is baked into every HLC
stamp already written, is the record path segment and the revision key. So
a device that has just switched ids must still recognise its former id as
its own -- otherwise skip-own-writes stops matching the old path, and the
device pulls back and re-merges its own pre-migration log as though a peer
had written it. Idempotent under LWW, but pure wasted transfer on every
tick.
Both halves therefore take an optional legacy id and test set membership
(own_ids / ownIds) rather than equality against a single id:
- crdt-sync (Python) 0.5.1 -> 0.6.0: new crdt_sync._device with
DeviceIdentity + load_device_identity (generate-or-load, persisted); the
mkdir is deliberately unguarded, since handing back an unpersisted id
would mint a fresh uuid every restart and strand a device dir each time.
sync_log gains legacy_device_id.
- crdt_sync_dart 0.6.0 -> 0.7.0: DeviceIdentity value type; syncLog gains
legacyDeviceId. Persistence stays app-side, where the existing uuid apps
already keep it in SharedPreferences under 'crdt.nodeId'.
Both changes are backward compatible: the parameter defaults to null, which
reproduces the previous single-id behaviour exactly.
Each half has a positive test and a negative control proving the old path
*is* pulled when no legacy id is declared -- so the skip is verified to be
the parameter's doing, not an artifact of the fixture.
Python: 239 tests, 100% branch coverage. Dart: 248 tests, analyzer clean,
device.dart 11/11 and sync.dart 57/57 lines covered.

Record.toJson() was writing the delete-clock field as deletedHlc while
the Python package's Record.to_dict() writes deleted_hlc -- an
undetected cross-language wire divergence: a tombstoned record synced
Python<->Dart would silently lose its delete clock on the receiving
side. Also widen syncLog's decode error handling from FormatException
alone to also catch TypeError, matching the Python side's
(ValueError, KeyError, TypeError) so a valid-JSON-but-wrong-shape push
from an incompatible writer is skipped per-device instead of aborting
the whole sync. Adds a fixture test shared verbatim with the Python
package's test suite so this class of divergence fails loudly going
forward.

Pure-Dart mirror of the Python crdt-sync package, module-for-module and
test-for-test, so the merge algorithm canonically agrees on both sides of
a sync between a Dart client and a Python one. No Flutter SDK dependency
(package:http only) per Workstream D's scoping decision (2026-07-04).
59 tests, clean dart analyze.
