Memory Standard Protocol (mm) for DeepSeek Harness

Key features

• Layered memory — MEMORY.md is the hand-loaded index (hard cap: 200 lines / 25 KiB, default)
• The on-disk format is plain, documented markdown (SPEC.md) and the URI scheme is mm:// / .
• detailed notes live in memories/ .md and load on demand.
• Deterministic budgets — over any budget is a structured error with usage metrics demanding an index rewrite, never a silent truncation.
• Writes carry a character budget and return usage so an agent can compress on the spot.
