[2026-11-11] setup | Vault scaffolded

Created raw/, wiki/, drafts/, AGENTS.md, index.md, log.md. Added two raw sources, not yet ingested: Karpathy’s LLM Wiki gist and EXO Labs’ DGX Spark Handbook.

[2026-11-11] ingest | DGX Spark Handbook (EXO Labs)

Discussed the five big ideas. Going slowly, one concept at a time. Wrote the source page, plus entity pages for the RTX 5090 and DGX Spark.

[2026-11-11] query | What is memory bandwidth on the 5090 spec?

Filed as memory-bandwidth: bus width × data rate, and why bandwidth (not size) sets decode speed.

[2026-11-11] query | How does bandwidth matter for cloud inference?

Added a cloud section to memory-bandwidth covering batching, the cost-versus-speed trade-off, and sizing a GPU when you deploy yourself. Added h100 and b200 to the comparison table.
