A server, and everything
that keeps it alive.

00 — AI / AGENT GATEReconcile before building

Any AI working on XCSV starts with the XCSV AI operating contract. If Architect says “read the GitHub” or “read the roadmap”, the agent first performs a read-only reconciliation of roadmap intent, RAG/history, local working trees, commits, GitHub/submodules and relevant live evidence.

01 — REPOSITORIESFour repos, one system

The hub carries documentation and submodule pointers. Everything else lives where it is built — and each has its own page here.

02 — ARCHITECTUREHow it fits together

The console supervises everything. One start, one stop — server, database, headless client and the local model come up and go down together.

The local language model is deliberately outside the critical path. It classifies and explains logs; it holds no tools, takes no actions, and its output is treated as untrusted data. Players have no path to it at all.

03 — HARD-WONFive things that cost real hours

Every one of these is now an automated check in XCSV GUARD, so it cannot cost them twice.

1. A corrupt PBO still passes a checksum verify. A leading \ on every entry path makes Arma resolve <prefix> + \path, find nothing, and silently never load the server core. Once produced 219 mission starts in eight minutes — and every visible error was a database error. Verifying is not enough; you have to read the entry table.
2. extDB3/x64 is production now. The old extDB2 bridge and 32-bit rollback artifacts were removed by policy. The server runs arma3server_x64.exe with -maxMem=12288.
3. -filePatching is mandatory. A3XAI reads its config as a loose file. Without the flag it silently ends the mission during world init and the server loops.
4. Arma's server simulation is single-threaded. SQF spawn does not create a thread — every scheduled script shares roughly 3 ms per frame on the main thread. More cores do not help. A headless client does.
5. Half the errors you can see are symptoms. Bridge errors and protocol noise can appear after the real failure. Count Starting mission: instead; more than one means a restart loop, and only the first error is real.

04 — STATUSWhat is running

05 — ROADMAPWhat comes next

Performance before content. Reconcile before implementation. The full roadmap lives in the documentation and the full engineering programme is in the GUARD Development Plan.

ELSEWHERE IN THE SYSTEMThe other three
