eb208579e3 refactor(daemon): centralize username path-segment sanitizer
Extract the inline path-traversal check from PendingStore into a shared
storage::safe_user::join_user_segment helper. RecoveryStore (next) reuses it.

5c94319bf0 feat(daemon): policy apply via pam-auth-update + lockout simulator (Phase 4+5)
Lands Lane 1 of the Phase 4+5+8+15+16 parallel cycle. Phase 4 + Phase 5 must
land together because both modify the SetPolicy code path.

- daemon/src/lockout.rs — pure simulate(new_policy, registry) -> Vec<Violation>.
  Iterates Required stacks, flags users with no enrolled credential of any
  required method. 5 unit tests cover: optional-mode skipped, required-with-
  unenrolled flagged, any-method-satisfies, empty registry, multi-stack.
- daemon/src/policy_apply.rs — PolicyApplier renders the pam-configs profile
  (Default: yes when any stack requires fido2; pam_u2f.so + pam_authforge_pending
  when fido2 required, only pam_authforge_pending otherwise) and runs
  pam-auth-update --package. Stash-and-restore on failure: prior profile
  contents are restored and pam-auth-update re-run, so a failed apply leaves
  the system in its previous PAM state. 4 unit tests including a real-process
  rollback test against a failing /bin/sh shim.
- daemon/src/state.rs — AppState::set_policy(p, force) returns
  PolicyApplyResult. Always runs the simulator first; if violations and !force,
  returns { applied: false, violations } without writing. Otherwise persists
  via PolicyStore::save and invokes PolicyApplier::apply. StorageConfig grows
  pam_profile_path + pam_auth_update fields (env-var driven, tests inject a
  no-op /bin/sh shim into a tempdir).
- daemon/src/dbus.rs — SetPolicy signature is now (Policy, bool) -> Result.
  Wire-breaking pre-alpha; CLI updated in this commit.
- cli/src/{bus,commands}.rs — set_policy takes force flag. policy set runs
  with force=false and surfaces violations as a non-zero exit + stderr list
  pointing the user at policy apply --force-i-know-what-im-doing. policy
  apply now actually invokes pam-auth-update via the daemon.

Test count: 42 daemon (was 33; adds 5 lockout + 4 policy_apply). 13 common.
5 cli. cargo clippy --workspace --all-targets -D warnings clean.

Plan deviation: PolicyApplier::from_env() became PolicyApplier::new(profile_path,
pam_auth_update) with the env defaults moved into StorageConfig::from_env_or_defaults.
Cleaner: state owns one source of truth for env-driven path config.

22938f657a feat(daemon-fido): Authenticator trait + Mock + Ctap impl + signals (Lane A)
Bundles plan tasks A2 (PamU2fCred encoder), A3 (Authenticator trait), A4
(MockAuthenticator), A5 (CtapAuthenticator wrapping ctap-hid-fido2 3.5.9),
A6 (wire enrollment through AppState::enroll), A7 (DeviceFound /
TouchRequired / EnrollmentSucceeded / EnrollmentFailed D-Bus signals).

- daemon/src/fido/format.rs — PamU2fCred -> 'kh,pk,es256,+presence' with
  hex::encode for the binary blobs and CoseType matching COSE alg -7/-8.
- daemon/src/fido/authenticator.rs — Authenticator trait with discover() and
  make_credential(rp_id, user, pin); AuthnError covers NoDevice / Cancelled /
  PinRequired / Backend.
- daemon/src/fido/mock.rs — MockAuthenticator::with_one_yubikey produces
  deterministic-but-distinct PamU2fCreds (counter-bumped per call).
- daemon/src/fido/ctap.rs — CtapAuthenticator. discover via
  ctap_hid_fido2::get_fidokey_devices(); make_credential via
  FidoKeyHidFactory::create + fk.make_credential. Heuristic error mapping
  to AuthnError variants. Real-hardware path; compile-clean gate only.
- daemon/src/state.rs — AppState::open now takes Arc<dyn Authenticator>.
  New enroll(user, nickname) replaces the Phase 2 add_credential stub: calls
  authn.make_credential, writes pam_u2f line via CredentialsStore::add,
  records enrollment in userdb, returns Credential with hex(keyHandle) as id.
- daemon/src/dbus.rs — enroll_own / enroll_other now emit TouchRequired
  before the call and EnrollmentSucceeded / EnrollmentFailed after. Removed
  the unused stub-credential builder + import baggage.
- daemon/src/main.rs — picks CtapAuthenticator for prod; tests inject Mock.

Test count: 33 daemon tests pass (was 26). Adds 2 fido::format tests, 3
fido::mock tests, 1 state::enroll_writes_real_pam_u2f_line, 1 dbus::
enrollment_succeeded_signal_fires_on_enroll_own. cargo clippy --workspace
--all-targets -D warnings clean. cargo fmt clean.

Plan deviations:
- HidInfo doesn't have a serial_number field in 3.5.9; switched to using
  product_string and HidParam::Path/VidPid for the device path label.
- FidoKeyHidFactory and LibCfg are at the crate root, not under fidokey::.
- fido/mod.rs has #![allow(dead_code)] for now: discover() and DiscoveredDevice
  fields are wired via the trait but only called from tests until Phase 8
  GUI consumes the DeviceFound signal.

24237cbf8b refactor(daemon): AppState delegates to storage modules; dbus tests use tempdir
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.

eb3362c81c feat(daemon): storage::credentials parser, CRUD, and per-user vs central path
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.

ea70386c2f feat(daemon): storage::policy + PolicyChanged signal + inotify watcher
Lands plan tasks 2.6 (PolicyStore wraps load_from_dir / save_local), 2.7
(PolicyChanged D-Bus signal on the AuthForge interface), and 2.8 (notify-based
inotify watcher in main.rs that emits the signal on any change in the policy.d
directory). Bundled because watcher → emit signal → wraps PolicyStore is one
data flow.

- daemon/src/storage/{mod,policy}.rs — PolicyStore::{load,save,watch}; watch
  returns a (RecommendedWatcher, watch::Receiver) so the caller keeps the
  watcher alive.
- daemon/src/dbus.rs — adds #[zbus(signal)] policy_changed; integration test
  via p2p connection asserts the signal arrives within 2s.
- daemon/src/main.rs — spawns a task that ticks PolicyChanged on every
  rx.changed(), keyed off AUTHFORGE_POLICY_DIR env var (default
  /etc/authforge/policy.d). Watcher leaked via std::mem::forget; daemon
  lifetime = process lifetime.

Test count: 17/17 daemon (was 14) + 13/13 common.

c26d6ae896 feat(daemon): D-Bus interface with all 9 stub methods + system-bus wiring
Bundles plan tasks 1.8 (read methods), 1.9 (EnrollOwn/RemoveOwn with polkit
gate), 1.10 (EnrollOther, SetPolicy, pending, recovery-code), and 1.11
(main.rs system-bus registration) — they land together because Polkit::System
is only constructed by main.rs, so splitting them mid-implementation would
require dead_code allows that immediately reverse.

Adds:
- daemon/src/dbus.rs — AuthForge struct + #[zbus::interface] impl with all 9
  methods. Reads (ListCredentials, GetPolicy) are unauthenticated; writes call
  authz() which dispatches to polkit. Includes 9 integration tests via a
  tokio::net::UnixStream::pair p2p connection — no system bus needed for tests.
- daemon/src/main.rs — connects to system bus, picks Polkit::system or
  Polkit::permissive based on AUTHFORGE_POLKIT_BYPASS env var, registers the
  AuthForge interface at /io/dangerousthings/AuthForge, requests well-known
  name io.dangerousthings.AuthForge, then parks forever.
- daemon/src/polkit.rs — drop dead_code allows now that System is wired.
- daemon/src/state.rs — gate has_pending() behind cfg(test); production reads
  go through the on-disk file in later phases, not this in-memory cache.
- common/src/types.rs (formatting only via rustfmt).

Tests: 14/14 daemon tests pass (4 state, 1 polkit, 9 dbus). 7/7 common tests
pass. cargo clippy --workspace --all-targets -D warnings clean. cargo fmt
clean.

f50c7b2e82 Rename project: ubuntu-fido -> authforge
Renames the package and all artifacts to authforge to drop the
distro-specific prefix, since the roadmap targets Ubuntu + Debian +
KDE + eventually Fedora (option C in the design).

- deb packages: authforge, authforge-{daemon,pam,cli,gui,gnome-integration}
- binaries: authforged, authforgectl, authforge (GUI)
- D-Bus name: io.dangerousthings.AuthForge
- PAM module: pam_authforge_pending.so
- Paths: /etc/authforge/, /var/lib/authforge/, /usr/share/pam-configs/authforge
- PPA: ppa:dangerousthings/authforge

Filesystem path /home/work/VSCodeProjects/ubuntu_fido/ left as-is for
historical reference; can rename later via git mv at the dir level.

Verified: cargo build/test/clippy/fmt clean, pam builds, gui builds,
all 5 debs produced.
