Address PR #227 re-review (comment 2193). - Stability: `updatePageId`/`updateAlias` now `executeTakeFirstOrThrow`, so a row reaped by a concurrent `removeAlias` between the read and the UPDATE (READ COMMITTED) raises `NoResultError` instead of returning `undefined`. The service maps that to a retryable `ConflictException` (`ALIAS_PAGE_RACE`) rather than a 200-without-alias (swap) or a generic 400 from `undefined.id` (rename). Tests cover both branches. - Simplification: drop the redundant secondary "unexpected unique index" warn and the now-unused `UNIQUE_ALIAS_INDEX` const (the constraint name is already logged unconditionally; both index branches still distinguish "Alias already taken" vs ALIAS_PAGE_RACE). - Architecture: extract `isUniqueViolation`/`violatedConstraint` into database/utils.ts; adopt them in the share-alias service and favorite.repo (the bare `23505` check). ai-agent-roles (#222) is on a separate unmerged branch and should adopt them after #227 merges (noted at the helpers). Helper unit test added. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
