session-persistence/ — persistence capability family

English | 中文

The durable session-persistence seam and its storage backends. The interface package owns the abstract SessionPersistence service and the shared write coordinator; the backends are concrete implementations that register on ctx.sessionPersistence. All product packages.

Package	Role	ctx key
session-persistence/	Persistence seam + shared write coordinator	ctx.sessionPersistence
session-checkpoint-policy/	Semantic durability barriers for agent requests and tool execution	(wraps ctx.llm / ctx.tools, listens on agent events)
session-persistence-jsonl/	JSONL-sidecar persistence backend	(registers ctx.sessionPersistence)
session-persistence-sqlite/	SQLite persistence backend	(registers ctx.sessionPersistence)

The interface lives at session-persistence/session-persistence/; backends are flat siblings. A new storage backend joins here and registers on ctx.sessionPersistence. See session persistence.
