pingqiuandClaude Opus 4.6 1c294af169 feat: CP13-4 — replica state machine / barrier eligibility contract + proof
Contract review: 6-state set (Disconnected, Connecting, CatchingUp,
InSync, Degraded, NeedsRebuild). Only InSync proceeds to barrier
request path. All other states either fail immediately or attempt
reconnect (must succeed before reaching barrier).

New test: TestBarrier_NonEligibleStates_FailClosed — systematically
verifies each non-eligible state (Connecting, CatchingUp, NeedsRebuild,
Disconnected) is rejected by Barrier(), and InSync is the only state
that enters the barrier request path.

5 baseline tests promoted to CP13-4 primary proof.
No production code changed — contract review + new focused test only.

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-block product structure clean enough to split into a separate repo later if needed

Suggested layout:

  • design/: shared V2 design docs
  • prototype/: 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 inside seaweedfs
  • likely future state: sw-block becomes a standalone sibling repo/product
  • design and prototype structure should therefore stay product-oriented and not depend on SeaweedFS-specific paths
