A compromised origin could serve a + matching payload. Code signing of releases and Ed25519-signed manifests are + planned, not implemented. +2. **macOS builds are unsigned and not notarised** (no Developer ID available), so + Gatekeeper warnings must be expected. +3. **File credential fallback** is obfuscation, not encryption. It is used only + when no OS secret service exists, and the UI says so. +4. **Third-party mods are arbitrary code** executed inside the game JVM by design. + Apeiron verifies download integrity, not the safety of mod behaviour. +5. **Microsoft sign-in requires a client id you register**, because shipping a + third-party application id would be misuse of that registration. + +## Scope + +In scope: the launcher, its native extension, packaging, and the update path. +Out of scope: vulnerabilities in Minecraft itself, mod loaders, or mods; issues +that require an already-compromised machine; and the absence of features listed +above as known gaps. diff --git a/csrc/_logcore_module.c b/csrc/_logcore_module.c new file mode 100644 index 0000000..c05e43c --- /dev/null +++ b/csrc/_logcore_module.c @@ -0,0 +1,252 @@ +/* + * Python bindings for the Apeiron logging core. + * Kept separate from logcore.c so that the core remains a pure-C module with + * its own standalone test harness (csrc/test_logcore.c). + * + * Copyright (c) Zerexa Ltd.

The translation completeness checker parsed `qsTr` line-by-line and produced + false positives for lines containing two calls; it now uses a regular + expression over each file (186 occurrences verified). +3. pip installs used backslash continuations, which are a parse error under + PowerShell — the default shell on Windows runners. +4. Update-check tests hard-coded a `linux` asset entry, so the checker correctly + found nothing on macOS/Windows; they now use `current_platform_key()`. +5. One launch test compared `argv[0]` with `/usr/bin/java`, which renders with + backslashes on Windows. +6. The GUI smoke assumed Chinese output while the product default is "follow + system" and runners are English; the run now pins a Chinese locale. +7. The UI requested font families that were absent on the macOS runner, making + Qt build alias tables and warn; families are now filtered against the ones + actually installed. +8. Nuitka could not see the package in a clean checkout; the build now performs + an idempotent editable install first. +9. The build workflow looked for `__main__.dist` while Nuitka names the + directory after the compiled entry script (`entry.dist`). +10. Nuitka copied the logging extension both as a data file and as a shared + library, colliding on macOS with `NotADirectoryError`; that scan is excluded. + +### Unresolved at the time of writing + +* **macOS and Windows Nuitka packaging still fail in CI.** The macOS job + progressed past the duplicate-copy crash but fails later in the Nuitka stage; + the Windows job fails as well. Neither could be reproduced here because no + macOS or Windows host was available, so the cause is **not diagnosed** and no + artifact is claimed for those platforms. Linux packaging is verified both + locally (§5) and in CI. +* **Windows GUI smoke** crashes the offscreen scene graph (0xC0000005) on the + GitHub runner and is skipped there with an explicit reason; the CI `qml` job + runs on Linux, where it passes. Windows GUI behaviour is therefore unverified. + +## 12.
