# LANE HANDOVER LOG Coordination file between lanes (Opus 4.8 execution sessions) and the reviewer (Fable). **Append-only** — never edit or delete previous blocks. Newest block at the BOTTOM. Push after every session so the reviewer can see state remotely. ## Protocol 1. Before starting work: read this whole file + your lane file in `lanes/` + `docs/CONTRACTS.md`. Check for a REVIEW block addressed to your lane — it overrides your lane file where they conflict. 2. Work only inside your lane's owned directories (see BUILD_PLAN.md §2). 3. End of session: append a SESSION block (template below), commit, push your `lane/` branch. 4. Never merge to main — the reviewer does that. 5. Blocked on a contract ambiguity? Don't stall and don't silently change the contract: stub locally with `// TODO(contract):`, log a CONTRACT CHANGE REQUEST below, keep moving. ## SESSION block template ```markdown --- ### SESSION —
