Paste a link → fetch its OpenGraph/meta preview (title, description, image,
site) and show a rich card. User-triggered + persisted (never auto-fetches;
cached so it never re-fetches). Opt-in via a new admin setting
enable_url_unfurl (default on, rule 26).
Security (the whole point of this task): a new dependency-free unfurl.py
does the fetch with layered SSRF defenses — http/https only; resolve the
host and reject EVERY non-public address (private/loopback/link-local/
reserved/multicast/unspecified — blocks 169.254.169.254 etc.); connect to
the vetted IP with SNI so DNS-rebinding can't slip through; ≤3 redirects
each re-validated; 5s timeout; 512 KB cap; text/html only; blocking IO in a
worker thread. No server-side image fetch — the og:image URL is loaded by
the browser.
- note_link_previews table (migration 0020), one per (note, url); serialized
inline on notes (+ rides the sync pull feed read-only).
- POST /api/notes/<id>/unfurl {url} (owner-scoped, setting-gated, 502 on
fetch failure); DELETE /api/notes/<id>/previews/<id>.
- enable_url_unfurl exposed in public config so the UI hides the affordance
when disabled.
Frontend: LinkPreview.vue card; editor detects URLs in the body and offers a
"Preview <domain>" chip per un-previewed link (ensureDraft first), renders
preview cards with remove; card shows previews read-only. New link icon;
notes-store unfurl()/deletePreview().
Tests (DB-free): is_public_ip range blocking, validate_url scheme/parts,
extract_preview (OG + <title> fallback + relative-image resolve), endpoint
auth-guards.

A note can now carry any file, not just images — PDFs, documents, audio
memos, etc. "Dump anything" capture.
Backend:
- note_attachments.filename (migration 0019) records the original name for
download + display.
- Upload drops the image-only mime gate: accepts any type, derives the
storage extension from the filename, and enforces a DB-backed per-file
cap — new setting max_attachment_mb (default 25, rule 25). App body
ceiling raised 12→64 MB (also lifts the import-zip / sync-push limits);
the per-file cap is the effective attachment limit.
- Serve sets Content-Disposition: images inline, everything else downloads
with its original (header-sanitized) filename.
- Import (native + Keep Takeout) now brings in ANY attachment, not just
images — completing the Keep audio-memo gap; preserves filename + sha256.
- Attachment metadata (delta feed + REST) carries filename.
Frontend:
- Editor renders attachments by kind: images inline (thumbnail), audio via
an inline <audio> player, any other file as a download chip (paperclip +
filename + size). File picker accepts any type; "Attach a file".
- Card previews the first image; non-image files show as compact chips.
Tests (DB-free): _safe_filename, _attachment_ext, _header_filename.

Let native clients sync attachment blobs deterministically:
- note_attachments gains sha256 (migration 0018, nullable, no backfill).
The delta feed's attachment metadata now carries size + sha256 so a
client knows exactly which blobs it already has (dedupe) and can verify
integrity after download.
- Upload accepts an optional client-supplied attachment id (multipart form
field), so a file attached offline keeps its identity across sync;
re-uploading an id the note already has is an idempotent no-op. The
server hashes the stored bytes (sha256) on upload. Download by id already
exists (owner/shared scoped).
Frontend Attachment type carries the new optional size/sha256.
(Still image-only mimes — broadening to any-file is task 1900. Blob sync
behavior is operator-verified on deploy.)

The core conflict-resolution step. Applies a batch of client changes,
additive + owner-scoped, with last-write-wins by client edit-time — and a
version-history snapshot on every overwrite so nothing is ever lost.
client_wins(client_edited_at, server_edited_at): apply iff client >= server;
a missing client time never overwrites a real server edit; a missing server
time (new row) yields. Notes compare against updated_at; labels gain an
updated_at (migration 0017, backfilled from created_at) as their LWW field.
Notes:
- upsert with a client-supplied id: create if absent, else LWW-apply the
full note state (title/body/color/kind/pins/trash/remind/position/items/
manual label_ids) with the same ripple as a web edit — derive_display_title,
_rewrite_links, _reconcile_tags (#tags), _rename_inbound_links. Overwriting
an existing title/body snapshots the old version into note_revisions first.
A resurrected tombstone clears purged_at.
- delete: purge tombstone (drop children + attachment files, clear content,
set purged_at), LWW-guarded so a newer server edit survives a stale delete.
Labels: upsert (create/rename/recolor) + delete (detach from notes, tombstone),
LWW-guarded; per-owner name-uniqueness clash on a different id is rejected
rather than raising.
Response: per-item {status: created|applied|kept|noop|rejected, sync_revision};
the client pulls afterward to converge. Whole-note semantics (client sends the
full state, not a partial patch).
Tests (DB-free): client_wins across all edit-time combinations; _parse_client_dt;
push auth-guard. Apply behavior + triggers operator-verified on deploy.

The delta-sync substrate for the local-first native clients (Tauri,
Android). No API behavior change — pure infrastructure; triggers are
operator-verified on deploy (no Postgres CI lane).
Migration 0015:
- CREATE SEQUENCE sync_revision_seq.
- notes + labels gain sync_revision (bigint) + purged_at (tombstone),
with existing rows backfilled to distinct increasing revisions.
- Trigger ts_set_sync_revision() BEFORE INSERT OR UPDATE on notes+labels
stamps a fresh monotonic revision from the sequence, so no mutation
site can forget to bump it (robustness over app-level bumps).
- Trigger ts_bump_parent_note_revision() AFTER INS/UPD/DEL on note_items,
note_attachments, note_labels re-bumps the parent note, since a note
syncs as a whole (items/labels/attachments travel inline).
- Indexes (owner_id, sync_revision) on notes + labels for the delta pull
WHERE sync_revision > cursor.
purged_at is the hard-delete tombstone (distinct from deleted_at = trash)
so an offline client learns a row is gone instead of resurrecting it.
Model columns added to Note + Label (nullable; trigger populates them).

A note's title+body is snapshotted on each edit that changes either, so an accidental overwrite can be viewed and restored (task 1906). Underwrites 'dump freely, nothing is lost'.
Backend: note_revisions table (migration 0014) + NoteRevision model; update_note records a revision of the PRE-edit state whenever title/body changes; GET /api/notes/<id>/revisions (newest 50) and POST /api/notes/<id>/revisions/<rev_id>/restore (snapshots the current state first so restore is itself undoable, then applies the revision with the usual title/body ripple — display name, links, #tags, backlinks). Title+body only in v1.
Frontend: a History toggle in the modal editor opens a panel of past versions (timestamp + preview) with per-row Restore. Store gains fetchRevisions/restoreRevision.
Migration 0014 runs on deploy; DB behavior operator-verified (no Postgres CI lane).

Fast, cross-device labelling: type #groceries in a note and it becomes
the "groceries" label. The body is the source of truth for tag-labels;
manual picker labels stay independent (rule 28 — additive).
- note_labels.via_tag (migration 0013) marks tag-sourced attachments.
- parse_tags(): #tag at start-of-body or after whitespace, needs a
letter (so #2024, URL #frags, mid#word are ignored). unit-tested.
- _reconcile_tags() on create + body-update: attach labels for current
#tags (find-or-create, case-insensitive), detach tag-labels whose tag
was removed; never touches manual (via_tag=false) rows.
- label picker (set_note_labels + editor onLabelsChange) now preserves
tag-labels on save, so a picker action can't strip a label the #tag
still mandates.
- serialize via_tag; card/editor chips render tag-labels as "#name",
and the editor hides the × on them (remove by editing the tag text).
- LabelPicker builds manual NoteLabels (via_tag:false).
Fourth and final item of M4.5.

Capture starts in the body, so forcing a title feels odd and body-only
notes had no name — which made them unlinkable. Fix both: persist a
display_title = explicit title if set, else the note's first non-empty
body line (deterministic, no AI). The title field stays optional.
- migration 0012: notes.display_title (NOT NULL, best-effort backfill;
the app recomputes precisely on next save)
- derive_display_title() helper, set on create + update
- drive the /titles index, backlinks, graph edges + node labels, and
[[wiki-link]] resolution off display_title so body-only notes are
nameable, findable (command palette / [[ autocomplete), and linkable
- rename-repoint generalized: inbound [[Old Name]] links now survive a
name change via the first body line too, not just an explicit title
- unit tests for the derivation (explicit wins, first non-empty line,
blank/empty, length cap)
- frontend: display_title on the Note type; title field placeholder now
reads "Title (optional)"
First item of M4.5 (frictionless input & recall); unblocks the linking
work. Card rendering unchanged (no first-line duplication).

Give labels a color (migration 0011 adds labels.color, server_default
'default' so existing labels keep the neutral chip). The PATCH endpoint now
updates name and/or color; note serialization carries each label's color.
Frontend: a swatch picker per label in the Edit-labels modal, colored chips
on cards + in the editor (LABEL_CHIP_CLASSES), and a color dot on each
sidebar label. Reuses the note color vocabulary. (Graph node coloring rides
this in the graph-liveliness task.)

- Frontend: titles store; LinkedText renders [[Title]] styled on cards; editor
shows Links (outgoing, resolve/create-on-click) + Linked-from (backlinks),
clicking navigates the editor to the target note (board + search).
- notes store: fetchOne, createTitled. DB-free link-parser tests.

- Migration 0008: notes.position (int). Board orders pinned -> position ->
updated_at; new notes created at top (max position + 1). POST /api/notes/reorder
assigns positions from the given order (owner-scoped).
- notes store: position on Note, position-aware sort, optimistic reorder().
- NoteCard reorderable (native HTML5 draggable + dragstart/drop); BoardView moves
the dragged note before the drop target and persists.
Note: drag on a CSS-columns masonry has imperfect during-drag visuals (columns
reflow); order persists correctly. Candidate for a polish pass / layout tweak.

MAX_CONTENT_LENGTH) stored under Config.media_root() (first use of DATA_DIR);
owner/ACL-scoped GET serves the file (nosniff); DELETE removes row + file.
