T0.3：完整表用 0002，写入队列暂不合并	decision	main/projects/25464650-ed5d-440e-b362-190f2852d451/t0.3-完整表用-0002-写入队列暂不合并	bcb76405-24ef-4daf-b346-f02f06d8dda7	project	decision	25464650-ed5d-440e-b362-190f2852d451	0c9feb46-d06e-43cd-9ef0-c5813c84a998	active	1	nixmsg-t03-decision-0002-20260930	2026-09-29T22:00:08.446242+00:00	2026-09-29T22:00:08.446242+00:00	t03 store migration

T0.3 决定：因 T0.1 的 0001_init.sql（SELECT 1）可能已写入已有库 schema_migrations，完整表结构放在新增的 0002_schema.sql，不改写 0001 语义。schema_migrations 表由迁移执行器 CREATE IF NOT EXISTS 维护。写入队列 T0.3 用互斥一操作一事务，合并提交留给 P2。
