Valid intent

ERDModel.renameTable / renameColumn keep schema identity changes inside the ERD domain model and update affected foreign-key references.

Review finding → TDD repair

The initial renameTable implementation deleted the old Map key and appended the renamed table with set(newName, table). That changed table iteration order. Because generateDDL() emits inline foreign keys in Map order, renaming an earlier referenced table such as users could move it after posts while posts still emits REFERENCES members(id). A rename must not silently perturb the model's existing dependency-safe order.

A focused regression in packages/web/src/lib/erd.rename.test.ts constructs users -> posts, renames users to members, and requires both getTables() and generated DDL to retain members before posts while updating the foreign-key target.

The minimal causal fix rebuilds the table map with the renamed key in the original entry position instead of delete+append.

Concurrent descendant reconciliation

The branch advanced normally from repaired head c0b5abc531226939d6a85309308008c09fb662ab to 42f814b3fdb086d68254c30575395d08e71153f8. Fresh compare is descendant-only (ahead_by=1, behind_by=0). The intervening commit refactors the same ordering implementation/test formatting and preserves the semantic contract: renamed table remains in its original position and generated DDL still emits the referenced table before the child FK. It is adopted rather than reverted; no force-push or destructive rebase is used.

Exact-head evidence

Fresh workflows for 42f814b3fdb086d68254c30575395d08e71153f8 are non-terminal: CI 33949269585, SAST Semgrep 33949269551, Security Scan 33949269591, and CodeQL PR 33949269561 are queued. The earlier repaired-head runs were cancelled and do not transfer.

Keep Draft until exact-head tests/checks and current review requirements are terminal-valid. Do not weaken the ordering regression, self-approve, bypass protections, or manufacture a source-neutral retrigger.
