All mutable state on Sender and Session is now unexported: - Sender.state, .epoch, .endpoint, .session, .stopped → accessors - Session.id, .phase, .kind, etc. → read-only accessors - Session() replaced by SessionSnapshot() (returns disconnected copy) - SessionID() and HasActiveSession() for common queries - AttachSession returns (sessionID, error) not (*Session, error) - SupersedeSession returns sessionID not *Session Budget configuration via SessionOption: - WithBudget(CatchUpBudget) passed to AttachSession - No direct field mutation on session from external code New test: Encapsulation_SnapshotIsReadOnly proves snapshot mutation does not leak back to sender state.

sw-block
Private WAL V2 and standalone block-service workspace.
Purpose:
- keep WAL V2 design/prototype work isolated from WAL V1 production code in
weed/storage/blockvol - allow private design notes and experiments to evolve without polluting V1 delivery paths
- keep the future standalone
sw-blockproduct structure clean enough to split into a separate repo later if needed
Suggested layout:
design/: shared V2 design docsprototype/: code prototypes and experiments.private/: private notes, phase development, roadmap, and non-public working material
Repository direction:
- current state:
sw-block/is an isolated workspace insideseaweedfs - likely future state:
sw-blockbecomes a standalone sibling repo/product - design and prototype structure should therefore stay product-oriented and not depend on SeaweedFS-specific paths
