From 7426295579efacf66298f592a31942c19ad3bfb1 Mon Sep 17 00:00:00 2001 From: t0kubetsu Date: Fri, 2 Oct 2026 11:27:43 +0200 Subject: [PATCH] feat(story-lifecycle): collision-safe, all-or-nothing ledger writes Route every .stories/ write through skills/story-lifecycle/scripts/ledger.js: - exclusive per-ledger lock; a second writer waits, then exits 3 without writing - story IDs reserved with exclusive-create markers in the git common dir, so concurrent agents and worktrees of one clone never share an ID - journaled batches: stage, journal, rename; derived epic/sprint tables are regenerated inside the batch; an interrupted batch is rolled back by the next write command or `recover`; `status` reports it only when no live writer holds the lock Bound the ledger to an opt-in planning projection that is never canonical ECC Task/Evidence/Completion/Integration state, and state that .stories/ follows the checkout. tests/docs/story-lifecycle-ledger.test.js exercises create, concurrent create, concurrent cross-worktree allocation, lock contention, overwrite refusal, interrupted-batch recovery, sprint planning, status drift and reconcile, and path confinement.
