Trash had no end. A note sat in /trash until someone emptied it by hand, and
its attachment BYTES sat on disk the whole time — the pile-up the operator
asked about. Nothing purged; there was no scheduler at all.

Retention is server-owned: `trash_retention_days` (default 30, 0 = keep
forever) in the settings registry, so it lands in admin Settings with no
migration and takes effect without a restart. A background sweep started in
before_serving does the work. Clients learn about a purge the way they learn
about any deletion — as a tombstone on the delta feed.

An auto-purge nobody can see coming is data loss on a timer, so the window is
now visible: /api/config publishes it, notes carry `deleted_at`, Trash leads
with the policy, and each card counts down. The countdown rounds DOWN — saying
"1 day left" for a note with ten minutes on the clock is the one error here
that actually costs someone a note.

Three things this turned up on the way:

- `DELETE /api/notes/<id>` hard-deleted the row, leaving no tombstone at all.
  A permanent delete in the web UI never reached a linked device, which would
  keep its copy forever and push it back on the next edit. It now purges
  through the same path as everything else.
- The purge left `note_revisions` and `note_link_previews` behind. A revision
  holds the full body, so the text of a "permanently deleted" note was still
  sitting in the database.
- `deleted_at` now SURVIVES a purge instead of being cleared. It's still true,
  and it means every query that says "not trashed" excludes tombstones for
  free — without it a content-less row reads as a perfectly normal active note
  and shows up on the board as a blank card.

Desktop keeps its own clock only when there's nobody else to keep one: the
sweep runs at startup on an UNLINKED device and refuses otherwise. A linked
client that expired notes on its own schedule could destroy something the
server was deliberately keeping, then push that delete upstream. Local policy
must never outrank the server's — so it also adopts the server's window for
the countdown rather than showing its offline default.

bvandeusenandClaude Opus 5 fbbe877c46 M10.6: client↔server sync protocol handshake (task 1995)

Version the sync WIRE PROTOCOL separately from either program's release
version, so a self-hosted server and the desktop app can sit on different
releases and still work out whether they can talk.

Each side declares two numbers — what it speaks, and the oldest counterpart
it accepts. Either side can therefore mark a change breaking without the
other shipping in step, which is the whole point: no app↔server lockstep.

Server advertises on the existing public /api/config (a client must be able
to ask "can I talk to you?" before it holds a device token, or even has an
account): sync_protocol_version, min_client_protocol_version, sync_features.

sync_features exists because a version number can only say newer/older. An
ADDITIVE change earns a capability name instead of a minimum bump, so a
newer client meeting an older server drops that one feature and syncs the
rest, rather than refusing. Raising a minimum is reserved for genuinely
breaking changes — it's the switch that hard-blocks the other side.

Client half is pure decision logic (sync/compat.rs), no I/O, so every branch
is unit-testable — there's no live-server lane in CI. Three outcomes: ok /
degraded{unavailable} / incompatible{reason, client_must_update}. The last
names which side can fix it, so the message is actionable. A server that
predates the handshake sends no protocol fields at all; that reads as
"update the server", deliberately not as a parse error, which would look to
the user like they mistyped the URL.

normalize_base_url defaults a bare host to https://, never http:// —
silently downgrading would put a long-lived device token on the wire in
cleartext because someone omitted five characters. Plain HTTP on a trusted
LAN stays supported; the user types http:// and thereby chooses it.

Transport (the actual fetch) lands next, separately: it needs an HTTP/TLS
stack, and that's a real risk to the Windows cross-compile lane, so it gets
its own CI run to bisect against rather than riding along with this.

No UI here by design — the link/settings surface it feeds is M10.7's, per
this task's own sequencing.

Policy documented in docs/sync.md.

bvandeusenandClaude Opus 4.8 7dd74d2946 Sync 6: sync protocol doc (docs/sync.md)
The contract the Tauri/Android clients implement against: device-token auth,
the shared-sequence revision cursor, note-as-sync-unit (+ derived links/tags
not synced), trash vs purge tombstones, pull (GET /changes) + push (POST
/push) request/response shapes, last-write-wins + history conflict policy,
attachment blob sync by id + sha256, and the idempotent/resumable sync cycle
(initial since=0 + resume). Docs only — CI paths exclude *.md.
