internal/httpapi/notes.go exposes:
- GET /api/notes list summaries {id, title, updated_at}
- GET /api/notes/{id} full {id, title, content, updated_at}
- PUT /api/notes/{id} create/update; ?base=<unix> for
optimistic-locking conflict detection
- DELETE /api/notes/{id} remove; ?base=<unix> guards against
deleting a row modified after the
client last saw it
Backed by tenant.FS so all reads/writes go through the per-user
sandbox — path traversal is rejected at parse time (regex slug)
and again by os.Root inside the FS layer.
On-disk format is plain Markdown: first line `# Title`, rest is
content. grep / cat / vim still produce a usable view of raw
files. Title round-trips through composeNote/splitTitle.
Conflict semantics: when the client supplies ?base=<unix>, the
server compares against the file's mtime. If the file is newer,
respond 409 with the current note body so the client can present
a merge UI. Same logic on DELETE returns 409 alone.
cmd/librenotes/serve.go grows a tenantPool that memoises FS
handles per user id; defer-closes them on shutdown.
Tests cover: full CRUD round-trip, cross-tenant isolation,
unauthenticated 401s, invalid IDs (regex rejection), and the
conflict path with a real mtime advance.
