Known scope and limitations

• The evaluated pair is gta_sa.apworld and SanAndreasAP-v0.9.0.zip from stable v0.9.0, published September 23, 2026. A newer v1.0.0-beta was published October 5; only its release metadata was checked here, and these badges do not evaluate that beta.
• Use classic Windows San Andreas 1.0; the native build specifically targets 1.0 US. Definitive Edition compatibility is not established. Install an ASI loader and Archipelago 0.6.7+, install the matching World, extract the mod into scripts, export a YAML with Options Creator and open GTA SA Client before launching the game. CLEO is optional; CLEO 4 or older is incompatible, while the author documents testing CLEO 5.4.0.
• Back up both game saves and their _ap.dat companions. The mod autosaves to slot 8 and uses a seed-and-slot-derived folder under GTA San Andreas User Files/archipelago. The game save and AP sidecar are separate writes without an atomic recovery mechanism.
• Keep the game and GTA SA Client running while reconnecting. Ordinary reconnects replay items, configuration and retained checks, but native pending reports are memory-only: restarting after a disconnected one-time check can lose its pending report. Victory retry exists within the live AP client, without a durable pending-victory record across client/game restart.
• The supplied starting-point files are credited user saves, not an identified full-game or DLC distribution. The reviewed native source lacks an explicit licence and the packages do not supply a complete notice/permission inventory for all bundled material. This is a documentation gap, without a legal infringement determination.
• Use a verified wss room address where available and avoid credentials embedded in the address: the inherited client defaults an unschemed address to ws and logs the full supplied URL. The game-to-client connection is loopback.
• The README still describes the mod as unstable and records a misaligned Caligula mission counter and autosave titles truncated around 22 characters. A counter-display issue alone is not treated as proof that mission logic is wrong.
• All 26 production World files match the fork tag after allowing line-ending differences; the package adds tests and manifest packaging fields. Forty supplied test files contain 331 test methods and were inspected without running them. Native PE metadata/imports were inspected, but a complete native binary-to-source match, build and game session were not established.
