ARCHITECTURE DECISION RECORDS / MASTER

Decisions form the architecture.

The 26 ADRs are not an unordered document pile. They define a dependency path from client contract to policy, transport, durability, and operational evidence. Browse the path first, then open the exact source decision.

DECISION DEPENDENCY / READING ORDER

Read causes before implementations.

A useful architecture review asks five ordered questions. The answer to each constrains the decisions that follow it.

  1. 01Client contract

    Define what callers may name and what remains below the boundary.

  2. 02Policy and placement

    Define ownership, admission, locality, and the control-plane authority.

  3. 03Transport and offload

    Define how bytes move, how congestion is bounded, and what DPUs may mediate.

  4. 04Durability and failure

    Define acknowledgement, mirror independence, recovery, and degraded behavior.

  5. 05Evidence and operations

    Define what proves capability, health, rollback, and restored protection.

Hot KV and Prefix Cache Data Plane

Makes Coherence-CE the exclusive logical boundary for hot KV and prefix-cache state, including hit, hydration, recompute, and durable-fetch behavior.

THIS DECISION ANSWERSHow does an inference actor find reusable state without learning storage topology?

Decision surface

This record is part of a layered system. Its concern is kept explicit so client contracts, memory placement, transport, offload, persistence, and operations can change without collapsing into one implicit implementation.
