- `session.append(type, data, opts?)` snapshots and freezes durable data and surface metadata, validates marker shape, provenance, and complete replacement coverage, commits synchronously, then notifies observers with independent failure containment. Reentrant attached-session appends reject, and runtime checks cover widened unions and loaded logs.
- `session.deriveMessages()` incrementally projects each new surface node once and returns a fresh array over shared frozen messages. A surface rewrite rebuilds the projection; there is no raw-log fallback.
- `session.deriveEventMessage(event)` is the canonical per-event projection used by reconstruction and invariants.
- `session.surface` lazily folds only new `surfaceOp` markers; `replaceGeneration` changes on every rewrite or invalidation.
- `session.surface` lazily folds only new `surfaceOp` markers; `replaceGeneration` changes on every rewrite.
- `session.events` is a cached frozen snapshot invalidated by append; accepted events remain deeply frozen.
- `session.seq`, `session.id` — current sequence and readonly typed identity.
- `session.header: SessionHeader` — detached, deep-frozen creation metadata (`version`, `id`, `createdAt`, optional `cwd`/`parentSession`/`seedLength`). Construction validates the durable record and requires its id to match `session.id`.
