Engram cartridges — pluggable fact memory for a frozen model

Engram cartridges are small, detachable n-gram fact memories (DeepSeek-style hash-keyed lookup tables) that mount onto a frozen base model in milliseconds, add exact-recall knowledge the base model cannot have, and unmount leaving the base byte-identical. Built with aoa-engram and runnable in llama.cpp (engram branch) natively or in the browser via a wllama fork.

Both Premier League seasons finished after the base model's training cutoff — the frozen model provably cannot know these results. The two football cartridges are trained against the base merged with the format LoRA (a fact cartridge must be built against the stack it runs on); the cities cartridge is trained against the bare base.

Query format is exact (see engram.md), e.g.:

Newcastle v Liverpool | result |   ->  2-3 (Liverpool)
Nanjing, CN | population |         ->  9314685
