- Unify directory structure across protocols:
* WebDAV: data/files/<username>/
* CalDAV: data/<username>/calendars/<name>/
* CardDAV: data/<username>/addressbooks/<name>/
- Add automatic migration capability that runs on server startup
- Maintain full backward compatibility with existing installations
- Improve Docker usage by automatically handling legacy data structure
- Updated storage provider implementations to use new nested structure
- Enhanced store functions for backward compatibility
- Modified CalDAV and CardDAV backends to use unified paths
- Added automatic migration logic in server initialization
Add db.DisplayName(username), returning the user's display name if
set, otherwise the raw username. Use it everywhere a shared calendar's
owner is shown: the web calendar legend ("shared by ..."), the "new
event"/edit calendar select label, the dashboard's "Shared with you"
list, and the CalDAV-side description/name-collision disambiguation
("Name (Owner)") shown to CalDAV clients like DAVx5.

Add a new /web/account page, reachable by clicking the username in
the nav, with two forms: updating display name/email, and changing
the password (requires the current password, min 8 chars, confirm
match). Add db.SetProfile to persist display name/email.

Users can now subscribe to a remote ICS/webcal feed from the dashboard
(name + color), the same way they set up a real calendar or the virtual
Birthdays calendar. Subscriptions are read-only, per-user, and share the
"/cal/home/<name>/" namespace with real calendars and "birthdays" (name
collisions are rejected in both directions).
- internal/db: new ics_subscriptions table + CRUD (internal/db/ics.go);
CreateCalendarWithColor checks for a colliding subscription name.
- internal/icssub: shared HTTP-fetch + TTL cache (15 min) for remote ICS
calendars, with webcal:// -> https:// rewriting and stale-on-error
fallback, used by both the web UI and the CalDAV backend.
- internal/web: dashboard "Subscribe to an ICS/webcal calendar" form,
color picker, delete button (internal/web/ics.go,
templates/dashboard.templ); month view renders subscription events in
their chosen color, read-only (internal/web/calendar.go).
- internal/caldav: subscriptions are exposed as read-only calendars
(internal/caldav/ics.go) - listed in PROPFIND, events served via
GET/REPORT, PUT/DELETE on individual events rejected with 403, but
DELETE on the calendar itself unsubscribes; calendar-color is injected
the same way as for real calendars and Birthdays.

- Add a per-user birthday_calendars table (color, cascade-deletes with
the user) and GetBirthdayCalendarColor/SetBirthdayCalendarColor in
internal/db, plus a reservedCalendarNames guard ("birthdays") in
CreateCalendarWithColor so no real calendar can collide with the
synthetic one, whether created via the web UI, nidusctl, or CalDAV
MKCALENDAR.
- Add a "Birthdays" virtual resource card to the dashboard (color
picker only, no delete/share controls) backed by a new
ResourceCard.Virtual flag and POST /web/resources/birthdays/color
handler.
- Extract the birthday-parsing/generation logic shared by the web
calendar view and CalDAV into internal/birthdays (ParseBirthday,
Collect, OccurrenceDate, Summary) instead of duplicating it.
- Expose the Birthdays calendar over real CalDAV in
internal/caldav/backend.go + birthdays.go: it's always listed for
every user, generates one VEVENT per (contact, year) for a rolling
window (current year -2..+8) with "🎂 Name (Age)" titles, is
read-only (Put/Delete/DeleteCalendar all return 403), and its
Apple/DAVx5 calendar-color is injected from the same per-user
setting used by the dashboard/web view.

Calendars can now have a color (hex, e.g. #3b82f6) that DAVx5 and other
CalDAV clients pick up via the Apple/dav4jvm calendar-color property.
- db: add calendars.color column with migration for existing DBs;
CreateCalendarWithColor, SetCalendarColor, GetCalendarColor;
ListCalendars now returns []Calendar{Name, Color} instead of []string
- caldav: since go-webdav's caldav.Backend interface has no extension
point for vendor properties, wrap the handler with a response-rewriting
middleware that injects <calendar-color xmlns="http://apple.com/ns/ical/">
into PROPFIND responses for calendars that have a color set
- web: color picker on the "New calendar" form and an inline color swatch/
picker on each calendar card (calendars only, not address books)
- nidusctl: `calendar create --color` flag and a new `calendar color`
subcommand; `calendar list` now also prints the color if set

BREAKING CHANGE: the users:/config-based collection setup is gone. All
user, calendar, and address-book data now lives in the SQLite DB
(internal/db) and is managed exclusively via nidusctl or the web UI.
Existing deployments must recreate their users after upgrading:
nidusctl user create <username>
nidusctl calendar create <username> <name>
nidusctl addressbook create <username> <name>
- internal/db: new users, calendars, addressbooks tables with FK cascade
delete; foreign_keys pragma enabled; internal/db/users.go implements
full CRUD + bcrypt auth (CreateUser, VerifyPassword, ListUsers,
CreateCalendar/AddressBook, etc).
- internal/config: removed Users/UserConfig entirely.
- internal/auth: Basic Auth now checks credentials via db.DB instead of
cfg.Users.
- internal/caldav, internal/carddav: ListCalendars/ListAddressBooks and
Create/Delete now backed by the DB.
- internal/web: login uses db.VerifyPassword; new resources.go adds
create/delete handlers for calendars/address books at
/web/resources/{calendar,addressbook}; dashboard gained create forms
and per-card delete buttons (templ + htmx, no hyperscript).
- tools/nidusctl: new user create/delete/list/passwd commands (masked
interactive password prompt via golang.org/x/term) plus create/delete/
list subcommands for calendar/addressbook.
- cmd/server/main.go: pre-creates on-disk collections from the DB at
startup instead of cfg.Users; warns when no users exist yet.
- Updated tests to seed data via the DB; added resources_test.go for the
new web UI handlers.
- README.md and .github/copilot-instructions.md updated to document the
new nidusctl commands and the DB-backed architecture.
Verified end-to-end against a live test server: nidusctl user/calendar/
addressbook create, DAV Basic Auth PROPFIND, web login, dashboard
rendering, and web UI create/delete of resources all confirmed working.

New internal/web package mounted at /ui/, separate from DAV Basic Auth:
- Cookie-based sessions (opaque random tokens in a new web_sessions
SQLite table, internal/db/sessions.go), checked against the same
cfg.Users/bcrypt credentials as DAV Basic Auth.
- Dashboard listing the logged-in user's own calendars/address books,
who they're shared with, and what's shared with them.
- Share/unshare directly from the dashboard, updated in place via htmx
partial swaps (POST to create/update, DELETE to revoke). Always
verifies the resource actually belongs to the logged-in user before
granting a share.
- Templates written in templ (internal/web/templates/*.templ, generated
*_templ.go committed), styled with Tailwind CSS v4 (web/input.css,
compiled to web/static/app.css), with htmx vendored as a static file
for the dynamic bits. Both are embedded into the binary at build time
(web/staticassets.go) so the compiled server has no Node.js/web/
runtime dependency.
- Wired into cmd/server/main.go at /ui/ alongside the existing /cal/,
/card/, /files/ routes; welcome page links to it.
- Tests: internal/web/server_test.go covers login success/failure, the
login-required redirect, dashboard rendering, share/unshare including
the htmx-v2-sends-DELETE-params-as-query-string quirk, and rejecting
shares of resources the user doesn't own.
- Docs: README (new 'Web UI' section, updated sharing section, project
layout, dependencies) and copilot-instructions updated accordingly.
Makefile: new templ-generate/web-deps/web-css targets.
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
- tools/nidusctl: subcommands `calendar {share,unshare,shares}` and
`addressbook {share,unshare,shares}`, thin wrapper around internal/db.
Warns (non-fatal) if owner/user isn't in config.yaml.
- internal/db: add SharesOfAddressBook (owner-perspective query, mirrors
SharesOfCalendar) needed by the CLI.
- internal/db: db.Open now creates the parent data directory itself, so
the CLI works standalone without requiring the server to have run first.
- Update Makefile (build bin/nidusctl, new 'nidusctl' target), README and
copilot-instructions with usage docs.

Introduce internal/db, a small SQLite-backed store (pure-Go
modernc.org/sqlite, no CGO) at <data_dir>/nidus.db holding
calendar_shares and addressbook_shares grant tables (owner, resource
name, shared-with user, read/write permission). This is the first step
towards user management and a web UI: a real datastore that a future
admin CLI/UI can build on, instead of the static config.yaml.
Wire sharing into the CalDAV/CardDAV backends:
- ListCalendars/ListAddressBooks now also include resources shared with
the requesting user, exposed under the synthetic local name
"<owner>~<name>" in the grantee's own home-set — no separate account,
no data copying, the object still physically lives under the owner's
store.Store namespace.
- All read paths (Get/List/QueryCalendarObjects, address book
equivalents) resolve the synthetic name back to (owner, real name) and
require any share (read or write) to exist.
- All write paths (Put/Delete object, DeleteCalendar/AddressBook)
additionally require a write-permission share; read-only shares get a
403 Forbidden.
- CreateCalendar/CreateAddressBook remain scoped to the acting user's own
namespace — sharing an existing collection is done via ShareCalendar/
ShareAddressBook, not by creating one directly in someone else's name.
Add internal/db/shares_test.go (grant/lookup/update/unshare/list
semantics) and internal/{caldav,carddav}/backend_test.go (shared
calendar/address book visibility, write permission enforcement,
unauthorized access rejection). Update README (features, new "Sharing
calendars and address books" section, project layout, dependencies) and
copilot-instructions.md to document the new package and sharing model.
