基于宁波生产 PostgreSQL 18 的只读预检，gateway_worker_instances 当前为 96 行、180224 字节，常量默认值新增列不会触发表重写，回填和约束验证范围可控。\n\ngateway_concurrency_leases 仅增加可空列；记录迁移校验器允许的 non-null column addition，并保留迁移文件不可变。\n\n验证：node scripts/ci-validate-migrations.mjs ac8d6dcf452ac555eb344f76caf6965c2ea42a97；./tests/ci/migrations-test.sh

"reason": "The migration adds only nullable session identity columns, backfills bound sessions, and replaces one CHECK constraint without dropping data. Production preflight on 2026-07-31 found zero gateway_oidc_sessions rows and a 48 KiB relation, so the constraint validation and metadata lock are bounded; the non-null finding comes from the new CHECK expression rather than a NOT NULL column addition."

"allowedViolations": [

|
"destructive DROP operation"

],

"allowedViolations": [
|
|
"non-null column addition"
|
|
],
|
|
"reason": "The adaptive Worker columns use constant defaults on gateway_worker_instances, so PostgreSQL 18 can add them without rewriting the table. Production preflight on 2026-08-03 found 96 rows and a 180224-byte relation; the explicit backfill and constraint validation are therefore bounded. The only change to the 31899648-byte gateway_concurrency_leases relation is a nullable numeric column and a NOT VALID check followed by validation."
