Maintain a server-side `page_links` index on every content change so
backlinks and missing-target ("phantom") links can be queried.
- prisma: `PageLink` (from_page_id, nullable to_page_id, target_slug;
unique per (from, slug); cascade on source purge, set-null on target
purge); migration.
- shared: `extractWikilinkSlugs(doc)` (distinct target slugs) and the
`BacklinkView` / `PhantomLinkView` read shapes.
- collab: the persistence hook (#35) now rewrites the source page's outgoing
links in the same transaction as the content cache — one row per distinct
wikilink slug, resolved to a page in the same pond (null = phantom).
- api: `GET /pages/:id/backlinks` (permission-filtered — wikilinks resolve
within a pond, so seeing the pond is the read right) and
`GET /ponds/:id/phantom-links` (missing targets grouped with their
referrers). Creating or renaming a page to a slug that pages already link
to resolves those phantom rows; because links store the target's id,
backlinks survive a later rename of the target's slug.
- tests: shared extraction unit test; collab persistence db test (store
writes resolved + phantom rows and rewrites the index); api LinksService
db test (backlinks, permission filter, phantom aggregation, create/rename
resolution, id-based backlinks survive target rename).

Introduce Obsidian-style `[[page links]]` (ADR 0004).
- shared: reserved `wikilink` inline atom in the editor schema (attrs
`targetSlug`, optional `displayText`); markdown mapping `[[slug]]` /
`[[slug|text]]` via a markdown-it inline rule + serializer node; plain-text
and HTML derivation include the shown text. Round-trip + parse unit tests.
- web:
- `Wikilink` node extension with a React NodeView: shows the explicit
display text or the target's current title (so a rename updates the link),
renders a missing target as a dashed phantom with a tooltip, navigates on
click in read mode.
- `[[` autocomplete popup (`WikilinkAutocomplete`), dependency-free: filters
the pond's pages as you type with a create-new-page hint for misses,
Enter/click inserts the node and removes the typed `[[query`; ↑/↓/Enter/Esc
intercepted in the capture phase so ProseMirror does not act on them.
- `WikilinkContext` provides the pond's pages (slug→title) for live
resolution and the autocomplete, populated by the page editor.
- i18n `editor.wikilink.*` (de + en); wikilink + phantom + popup styles.
- e2e `wikilink.spec.ts` (new CI pack): type `[[`, autocomplete filters and
inserts a working link that resolves the target title and persists across a
reload. Phantom → live resolution on page creation is verified in #47.

A bubble menu on link selection offers "edit URL", "open in new tab",
and "remove link"; Mod-k opens the same editor for the current
selection (creating a link if there isn't one yet), and the toolbar
button does the same. Invalid protocols (e.g. javascript:) show a
localized inline error instead of silently no-oping. Pasting a URL
over selected text links it instead of replacing the text.
Links always render with target="_blank" so read mode opens them in a
new tab by default; edit mode suppresses the resulting navigate-on-
click (Mod-click still follows it), since a plain click there should
place the cursor instead.
Closes#29
Paste and drag-and-drop of image files upload via the #27 API and insert
a real image node only once the upload succeeds; the in-flight state is
a ProseMirror decoration, not a document node, so a failed upload cannot
leave anything broken behind (it shows a transient inline error instead).
The toolbar's image button opens a native file picker into the same
upload path. Selecting an image reveals inline alt-text and width-preset
(small/medium/full) controls. Also fixes the image node's parseDOM,
which had no getAttrs and would drop the required fileId attribute on
internal copy/paste.
Closes#28
The #24 commit passed ESLint but not the repo's Prettier check (pnpm
lint runs both) — CI caught it after the push. Formatting only, no
behavior change.
ProseMirror schema (headings 1-4, lists incl. task lists, blockquote,
code block, tables via prosemirror-tables, images, hard breaks; bold/
italic/code/strikethrough/link marks) plus docToMarkdown, markdownToDoc,
docToPlainText, docToHtml, and extractOutline built on it. Markdown
parsing extends markdown-it's default preset with a token-stream
transform for GFM task lists and table-cell paragraph wrapping.
docToHtml hand-rolls escaping and link-protocol allowlisting with zero
DOM dependencies, so it runs in the API/collab server as well as the
browser.
Node names `wikilink` and `plugin_block` are reserved for later stories.
Closes#24
