**Model-visible ⟺ logged**: messages entering at `step/start` plus the folded `request/header` reconstruct every request. The header marks adapter defaults so later proposals discard them and re-resolve the route without losing explicit settings. `request/context` separately records registration-bound provider, model, and capacity metadata when the route changes; it does not participate in request reconstruction or header equality. `dsh-agent-loop/invariant` asserts reconstructability through `ctx.invariants` ([reconstructability](../.agents/notes/implemented/architecture/2026-07-05-reconstructable-requests.md)).
Durability is a plugin concern. Backends copy synchronous `session/event` notifications into fixed-window durable batches; `session/flush` bypasses the wait before requests and top-level tool dispatch, and after `turn/end` before another turn or idle. `SessionPersistence` stores events and header metadata; JSONL defaults to checksummed Zstandard and SQLite shares the contract ([checkpoint decision](../.agents/notes/implemented/bug-fix/2026-07-21-semantic-session-checkpoints.md), [batching decision](../.agents/notes/implemented/architecture/2026-08-08-bounded-session-persistence-write-batching.md)).
Durability is a plugin concern. Backends copy synchronous `session/event` notifications into fixed-window durable batches; `session/flush` bypasses the wait before requests and top-level tool dispatch, then follows `turn/end` before another queued turn or idle observation. A listener returns literal `true` only after durability work completes; a successful acknowledged barrier publishes contained `session/flushed(session, throughSeq)` with the exclusive event boundary captured at entry, so commit-aware projections can advance without treating append notification as durability. `SessionPersistence` stores events and header metadata; JSONL defaults to checksummed Zstandard and SQLite shares the contract ([checkpoint decision](../.agents/notes/implemented/bug-fix/2026-07-21-semantic-session-checkpoints.md), [batching decision](../.agents/notes/implemented/architecture/2026-08-08-bounded-session-persistence-write-batching.md)).
Between turns, owners append log-only events through `Session`, flushing only for durability. `session/title` relies on bounded background persistence and lifecycle drains; manual compaction flushes its bracket before the operation completes. Title work never delays responses; the latest title event wins, and it records the source message seqs and whether the user, fallback, or provider supplied it. Title records are inherited fork boundaries ([decision](../.agents/notes/implemented/feature/2026-07-21-log-backed-session-titles.md)).
