This sprint focuses on shipping the editor redesign and stabilizing mobile sync. Review the engineering priorities before standup.
Sprint Goals
Our primary objective is to deliver a 10× faster editor while keeping the block model backward-compatible. Secondary work targets reducing mobile sync latency below 120ms p95.
Deliverables
Block renderer rewrite with virtualization for 1,000+ blocks
Conflict-free sync layer powered by CRDTs — see Architecture Decisions
Public API for third-party block plugins @beta
Checklist
Finalize CRDT merge semantics
Profile virtualized scroll on low-end Android
Write migration runbook for v2 → v3 schema
Key Risks
Performance regression on large docs
Virtualization may break block-level copy/paste semantics. Mitigation: keep a ±50-block window around the caret and fall back to full render under 500 blocks.
Third-party plugin sandboxing
Timeline
⚠️
Feature freeze is Jan 24. Anything merged after rolls into v3.1.
We hold a dry-run of the migration on staging every Friday at 2pm. Owners should update this tracker after each run.
Milestones
✅
CRDT prototype passed all conflict-resolution benchmarks on Dec 18. Shipping to production this sprint.
