codex-plan-ledger: Adding a decision ledger to Codex Plan mode
Understand the story
On 2026-10-12, an AI coding article on Juejin introduced codex-plan-ledger: it writes the decisions made in Codex Plan mode (/plan) to docs/plans/<id>/decisions.json inside the repository, so those decisions can be diffed and reviewed in the same PR as the code; it also provides the plan-ledger check --base main command to check for scope drift. According to the report, the tool's purpose is to leave a traceable record of the trade-offs made during planning, rather than leaving them only in the conversation. Progress so far is limited to the tool introduction and command usage; the report does not mention adoption or follow-up updates.
