## Unreleased — 2026-05-21 (Audit remediation P0/P1/P2)
|
|
|
|
### Security (P0)
|
|
- **Secrets at rest**: Added `_mask()` helper in `config.py` to redact credentials from any
|
|
debug log output. Added `SETTINGS_SCHEMA_VERSION` and prominent plaintext-storage warning.
|
|
- **GOST integrity**: `gost_util.py` now verifies the downloaded release zip against a pinned
|
|
SHA256 (`GOST_RELEASE_ZIP_SHA256`) before extraction. Supply-chain swap raises `RuntimeError`.
|
|
- **Kill-switch recovery**: `firewall.py` exposes `emergency_disengage()`. `service.py`
|
|
registers it via `atexit` and `signal.SIGTERM`/`SIGINT` so a crash cannot leave outbound
|
|
traffic permanently blocked.
|
|
|
|
### Reliability (P0/P1)
|
|
- **Top-level exception handler**: `app.py` `main()` now catches unhandled exceptions, shows a
|
|
`tkinter.messagebox` error dialog, logs to file, and re-raises.
|
|
- **Log rotation**: `app.py` switches from bare `FileHandler` to `RotatingFileHandler`
|
|
(5 MB max, 3 backups).
|
|
- **Settings migration**: `config.py` gains `settings_version` field, `migrate()` function, and
|
|
safe corrupt-file backup (`settings.json.corrupt`) on parse failure.
|
|
- **Settings backup**: `save_settings()` copies `settings.json → settings.json.bak` before
|
|
overwriting.
|
|
- **Graceful shutdown**: `service.py` `stop()` calls `fw_emergency_disengage()` if the thread
|
|
does not exit within 15 s.
|
|
- **Thread safety**: `ChainService._settings` reads/writes guarded by `threading.Lock`.
|
|
- **Input / URL validation**: `sanitize_settings()` now validates `sources` and `ip_check_url`
|
|
against an RFC-1918 / link-local block-list; unsafe entries are removed with a warning.
|
|
|
|
### CI / Distribution (P0/P1/P2)
|
|
- **GitHub Actions CI** added: `.github/workflows/test.yml` runs `compileall` + `unittest
|
|
discover` on Python 3.10 / 3.11 / 3.12 on `windows-latest`.
|
|
- **LICENSE**: MIT license added to repo root.
|
|
- **requirements.txt**: All four runtime dependencies pinned to exact versions; `cryptography`
|
|
listed for optional future credential encryption (not yet wired).
|
|
- **`.gitignore`**: Added `settings.json`, `*.json` credential files, and screenshot noise.
|
|
- **`--version` flag**: `run.py` now supports `--version` / `-V`.
|
|
|
|
### Documentation (P1/P2)
|
|
- **`docs/OPERATOR_RUNBOOK.md`**: Emergency firewall disengage, proxy leak, empty pool, GOST
|
|
quarantine, and settings-restore instructions.
|
|
- **Bare `except: pass` cleanup**: Key silent-failure sites in `tray.py`, `dns_leak.py`, and
|
|
`gost_util.py` now log a `warning` or `debug` message instead of swallowing errors.
