a462b2cf06 feat: add fprintd fingerprint authentication via greetd multi-stage PAM (v0.6.0)
Fingerprint auth was missing because moongreet rejected multi-stage
auth_message sequences from greetd. With pam_fprintd.so in the PAM
stack, greetd sends non-secret prompts for fingerprint and secret
prompts for password — moongreet now handles both in a loop.

- Replace single-pass auth with multi-stage auth_message loop
- fprintd D-Bus probe (gio::DBusProxy) for UI feedback only
- Fingerprint label shown when device available and fingers enrolled
- 60s socket timeout when fingerprint available (pam_fprintd scan time)
- Config option: [appearance] fingerprint-enabled (default: true)
- Fix: password entry focus loss after auth error (grab_focus while
  widget was insensitive — now re-enable before grab_focus)

77b94a560d fix: prevent edge darkening on GPU-blurred wallpaper (v0.5.3)
GskBlurNode samples pixels outside texture bounds as transparent,
causing visible darkening at wallpaper edges. Fix renders the texture
with 3x-sigma padding before blur, then clips back to original size.
Symmetric fix with moonset v0.7.1.

b06b02faac refactor: remove embedded wallpaper from binary (v0.5.2)
Wallpaper is installed by moonarch to /usr/share/moonarch/wallpaper.jpg.
Embedding a 374K JPEG in the binary was redundant. Without a wallpaper
file, GTK background color (Catppuccin Mocha base) shows through and
wallpaper-only windows on secondary monitors are skipped.

7c10516473 fix: re-audit findings — avatar path safety, persistence logging, tests
- Reject non-UTF-8 avatar paths early instead of passing empty string to GDK
- Log persistence write failures with warn! instead of silently discarding
- Reduce API surface: create_background_picture pub→fn
- Add boundary test for MAX_USERNAME_LENGTH and socket connect failure test

09371b5fd2 fix+perf: audit fixes and GPU blur migration (v0.5.0)
Address all findings from quality, performance, and security audits:
- Filter greetd error descriptions consistently (security)
- Re-enable power buttons after failed action (UX bug)
- Narrow TOCTOU window in avatar loading via symlink_metadata (security)
- Allow @ in usernames for LDAP compatibility
- Eliminate unnecessary Vec allocation in passwd parsing
- Remove dead i18n field, annotate retained-for-future struct fields
- Fix if/if→if/else and noisy test output in power.rs

Replace CPU blur (image crate + disk cache + async orchestration) with
GPU blur via GskBlurNode — symmetric with moonlock and moonset.
Removes ~15 transitive dependencies and ~200 lines of caching code.

3c39467508 perf: cache blurred wallpaper to disk to avoid re-blur on startup
First launch with blur blurs and saves to /var/cache/moongreet/.
Subsequent starts load the cached PNG directly. Cache invalidates
when wallpaper path, size, mtime, or sigma changes.

293bba32a6 feat: add optional background blur via image crate
Gaussian blur applied at texture load time when `background-blur` is
set in the [appearance] section of moongreet.toml. Blur runs once,
result is shared across monitors.

14d6476e5a fix: audit findings — wallpaper safety, log filtering, error truncation (v0.4.1)
- Rework load_background_texture(): use resources_lookup_data()/from_bytes()
  for GResource path (no abort on missing resource), add 50 MB file size limit,
  handle non-UTF-8 paths gracefully
- Filter error details to debug level only — warn! logs without internal details
  to prevent system info leaking into journal
- Make debug logging opt-in via MOONGREET_DEBUG env var (default: Info)
- Truncate greetd error description in stale-session retry path using
  MAX_GREETD_ERROR_LENGTH (matching show_greetd_error())
- Add 3 unit tests for load_background_texture edge cases

96c94f030a feat: switch to systemd-journal-logger, add debug logging (v0.4.0)
Replace env_logger file-based logging with systemd-journal-logger for
consistency with moonlock and native journalctl integration. Add debug-level
logging at all decision points: config loading, user/session detection,
avatar resolution, locale detection, IPC messages, login flow, and
persistence. No credentials are ever logged.

0d4a1b035a fix: audit findings — security, i18n, validation, dead code (v0.3.2)
Quality:
- Q-5: Allow relative session commands (e.g. niri-session), greetd resolves PATH
- Q-3: Socket read+write timeouts with proper error logging
- Q-2: Remove unused PowerError::Timeout variant
- Q-M1: i18n for all login_worker error messages (new: unexpected_greetd_response)
- Q-M2: Explicit INVALID_LIST_POSITION check in session dropdown
- Q-M4: Log SVG loader.close() errors instead of silencing
- Q-M6: Testable persistence functions with proper roundtrip tests

Security:
- S-2: Validate GTK theme name (alphanumeric, _, -, +, . only)
- S-3: Log file created with mode 0o640
- S-4: Cache files (last-user, last-session) created with mode 0o600

Performance:
- P-3: Single symlink_metadata() call instead of exists() + is_symlink()
- P-4: Avoid Vec allocation in IPC send_message (two write_all calls)

Config:
- Update example GTK theme to Colloid-Catppuccin

4fa0dd0ead fix: GECOS subfield trimming and trailing backslash handling (v0.3.1)
display_name() now returns only the first GECOS subfield (before comma)
instead of the full GECOS string with room numbers and phone extensions.

split_shell_words() returns None for trailing backslashes instead of
silently ignoring them.

226bbb75e4 Rewrite moongreet from Python to Rust (v0.3.0)
Complete rewrite of the greetd greeter from Python/PyGObject to Rust/gtk4-rs
for consistency with moonset, single binary without Python runtime, and
improved security through Rust memory safety.

Modules: main, greeter, ipc, config, i18n, users, sessions, power
86 unit tests covering all modules including login_worker IPC flow.
Security hardening: shell-word splitting for exec_cmd, absolute path
validation for session binaries, session-name sanitization, absolute
loginctl path, atomic IPC writes.
