It previously fetched the folder list and threw it away into a status
line — a button that looked like it worked and did not. Now it opens a
browsable picker: click a folder to descend, ".." to go back, "Use this
folder" to select, "Cancel" to leave the root unchanged.
Descends one level per click because that is what the backend supports:
Depth: infinity is frequently disabled server-side and prohibitively
expensive where it is not (ARCH §8.4).
The chosen root persists immediately on confirm, so it survives a crash
before the library is opened. Confirming at the account root is allowed —
a user may legitimately keep everything at the top level — and cancelling
leaves any previous selection untouched, which a test asserts.
Verified against nextcloud.tourolle.paris at both depths: 30 folders at
the root, 21 year-folders inside PhotosRaw.
19 launch tests, 38 in dr-ui.
Login now persists properly rather than through the JSON file the test
harness was using.
dr-plat SecretStore trait plus a Secret Service backend.
Verified against the live GNOME Keyring: store,
retrieve, delete, confirm-gone all round-trip.
Session/SessionStore splits credentials from settings — the app
password goes to the keyring (FR-NC-2), while
server, login, chosen root and format selection are
ordinary config. A test asserts the credential never
appears in the config file.
LaunchModel the launch-screen state machine, testable without a
display server: sign in, approve in browser, choose
folder, tick formats, sign out.
launch.slint the screen itself, in its own file.
Absence of a secrets daemon is an explicit degraded mode, not a silent
fallback to plaintext — the screen says sign-in will not persist rather
than letting the user find out next launch. Android's Keystore backend
fails loudly for the same reason: a no-op store would look like it
worked and then lose the credential.
Two bugs caught by tests rather than by running it:
- fail() after busy() signed the user out, because busy() had already
discarded the session. A failed *scan* would have logged you out.
Busy now carries the session.
- normalise_server upgrades http:// to https:// rather than accepting
it. NFR-SEC-3 requires TLS, and silently sending a credential in the
clear is not a decision to make on the user's behalf.
launch.slint is not yet wired into app.slint. Calling slint_build::compile
twice replaces the generated module rather than adding to it, which broke
the other in-flight work on dr-ui; I reverted that immediately. Wiring it
needs an import inside app.slint, which is that work's file to change.
