Lands plan tasks 2.15 (AppState refactor with StorageConfig + open()) and 2.16
(dbus.rs tests switched to tempdir-backed AppState; storage errors threaded
through D-Bus methods as Failed). Bundled because the AppState surface change
forces dbus.rs adjustments in the same commit.
- daemon/src/state.rs: AppState::open(StorageConfig) replaces with_fixtures().
StorageConfig.from_env_or_defaults() reads AUTHFORGE_POLICY_DIR /
_PENDING_DIR / _USERDB env vars (defaults: /etc/authforge/policy.d,
/var/lib/authforge/pending, /var/lib/authforge/users.db). State delegates
list/add/remove credentials to CredsPathResolver + CredentialsStore picked
per-call from current Policy; pending and userdb operate independently.
- daemon/src/main.rs: opens state via env-driven config; reuses cfg.policy_dir
for the watcher to keep one source of truth.
- daemon/src/dbus.rs: every write method maps StateError to fdo::Error::Failed.
p2p_pair seeds 00-test.conf with [storage] backend = central pointing into
the tempdir so credential writes don't try to touch /home/<user>/...
(alice/bob/carol aren't real accounts in tests).
- Renamed: list_credentials_returns_fixture_for_alice ->
list_credentials_after_enroll. Removed: with_fixtures().
- .gitignore: add .claude/ so leftover Phase 1 worktree state isn't committed.
Test count: 26/26 daemon tests green (was 17). Common: 13/13. Clippy + fmt clean.
Lands plan tasks 2.10 (pam_u2f line format parser via CredEntry::from_line/
to_line, credId extraction), 2.11 (CredentialsStore add/remove/list with
idempotent add-by-credId), and 2.12 (CredsPathResolver dispatching central vs
per-user paths). Bundled because the three pieces compose into one storage
boundary.
CredEntry treats post-username chunks as opaque blobs split on ':', preserving
pam_u2f's full record on round-trip. credId = first comma-separated field of a
blob. add() is idempotent on credId match (Phase 3 may decide to refresh
publicKey on re-enroll; out of scope here).
Path resolution: Central -> Storage.central_path verbatim. PerUser -> getpwnam
via nix, with a /home/<user>/... fallback if NSS errors (CI users, distro
quirks); pam_u2f does the real lookup at auth time, so the fallback only
matters for write-on-enroll where the user does exist.
7 tests added; clippy + fmt clean.
