Add a SQLite SessionPersistence backend (node:sqlite), a SECOND implementation built to prove the abstract seam + the shared runPersistenceContract suite are genuinely backend-agnostic. Each SessionEvent maps 1:1 onto an events row (session_id, seq, type, time, data); append is an INSERT inside a transaction asserting the contiguous-seq contract; the mutable SessionSummary lives in the sessions metadata row. It satisfies the SAME contract semantics as the JSONL backend, expressed over rows instead of file bytes: - Lazy materialization: create() records intent in memory; no row until the first append (a never-appended session is absent from has()/list() via a materialized flag set inside the first append transaction). - Crash-tail-on-load: load() returns events only through the last complete turn/end and deletes the uncommitted tail; a seq gap in the committed region makes the session unloadable. - Transactional append: a mid-batch failure (a UNIQUE seq collision from a concurrent writer) rolls back entirely, keeping the cursor truthful. Like the JSONL backend it is also the write-path plugin (session/event → buffer → session/flush drain, onCreated seed/adopt/collision handling, HMR seeding, dispose-to-quiescence). The package runs the shared runPersistenceContract suite plus SQLite-specific tests (transaction rollback, crash-tail cut, schema version, HMR adoption). Docs flip every "SQLite is future/deferred" reference (ADR 0016, architecture.md, the persistence module doc + README) to "implemented; the contract holds both backends to identical semantics".
