B69 — spurious `(sync-conflict)` copies came from `(mtime, size)` being used as a
revision identity. The server re-stamps a sealed revision with its own commit
time, so the drain diverted a write into a conflict copy of its own base; and
`plan_file` classified a no-baseline (local, remote) pair as `Conflict`, forking
every pre-existing file on first reconcile.
- `Baseline` carries `revision_id` (from the SDK's new `active_revision_id`),
captured at write-open and preserved across supersede/rebaseline.
`revision_changed` trusts the id and only falls back to `(mtime, size)` for
old sidecars.
- Planner gains `FilePlan::AdoptBaseline`: equal-size no-baseline pairs are
recorded, not conflicted. Divergent sizes stay a real conflict.
- New `sweep.rs` (`pdfs-conflict-sweep`, 5-min cadence) removes conflict copies
proven identical by size + `content_sha1` and surfaces divergent ones once as
an `ActivityKind::Conflict` entry. Never removes what it cannot prove.
B70 — browsers downloading into an on-demand mount had their in-flight temps
sealed as canonical revisions, exiling the finished file to a conflict copy.
`syncignore::is_transient_name` now recognises download/scratch temps, and the
on-demand `release`/`rename` paths hold them (`set_create_hold`) instead of
sealing until the name is finalized.
Workspace deps bumped to proton-sdk/proton-drive-rs 0.2.2 (registry, no patch).
Live validation against a real account still pending for both.

- Durable scratch/staging publication and preservation on failure.
- Transactional pending-operation supersession.
- Conflict copies cannot overwrite older copies or lose the source.
- Single-entry wipe protection and incomplete-scan aborts.
- Failed local deletion retains its baseline.
- Downloads are fsynced before baseline settlement.
- Future database schemas are refused.
- Event cursors advance only after successful invalidation and persistence.
- IPC frame, timeout, and concurrency limits.
- Atomic config saves; malformed configs are preserved.
- Sensitive directories require correct ownership, real directories, and 0700.
- Debian package now includes service and tray autostart files.
- Release workflow enforces versions, tests, lint, formatting, and offline acceptance.
- CI now runs offline filesystem acceptance.

relocate() called forget(), dropping the node's by_uid mapping, so
the re-enumeration assigned a fresh inode. The kernel had already
carried the renamed dentry onto the old one and holds it for the
entry TTL, so lookup/getattr/opendir resolved to an inode entries
no longer held and returned ENOENT — while readdir walked children
and reported the new inode. A renamed directory listed in its
parent but could not be entered until the TTL expired.
Rewrite the node in place and invalidate both parents' listings
instead. Also stops the moved node's DB row being deleted and
recreated on every move, which the B1 data-loss fix worked around
