# Current Research Context (Global)

## Global Password‑Vault Index
- Canonical names: `MemRelay Administrator`, `BDYG18Pro Armbian SSH`, `OpenWrt Router SSH`, `Public FRPS Server SSH`, `FRP ali.asio.asia Token`, `Gitea git.asio.asia OAuth`, `Armbian MySQL Root`.

## Network Stack Adjustments (TSO & Cubic)
- Hardware TSO incompatible with RTL8367S DSA; removed `snps,tso` from the DTB. Default TCP congestion algorithm switched from Reno to Cubic.

## Flashing & Recovery Safety Rules
- Do **not** flash the generic RK3568 image. Use the project‑provided U‑Boot, DTB, and RTL8367S/DSA configuration. Verify storage type, image SHA‑256, and backup status before writing.

## Production‑grade MCP JSON Serialization
- Objects containing `datetime`, `UUID` or Pydantic models must be passed through FastAPI `jsonable_encoder` before `json.dumps`.

## Vault Performance Audit
- In‑process Bitwarden snapshots reduce list/search latency from ~20 s to ~0.4 s on ARM64. All audit checks pass.
