## PR Review: paper-dynasty-database#49

**Verdict:** APPROVED (posted as COMMENT — Gitea blocks self-approval)

**Files reviewed:** `app/db_engine.py`

**Changes:**
1. Added block comment above the SQLite `pragmas` dict documenting `synchronous=0` (crash-corruption risk, WAL mitigation, dev-only scope). Technically accurate.
2. Undocumented second hunk: reformatted `db.create_tables([...])` at line 933 to multi-line with trailing comma — cosmetic only.

**Key findings:**
- Documentation-only PR, no functional changes.
- Comment is correct and proportionate.
- PR body omitted the second formatting hunk — minor omission, flagged in review as suggestion.
- Gitea error "approve your own pull is not allowed" — fell back to COMMENT state.

**Note:** `synchronous=0` is intentionally dev-only; production uses PostgreSQL via `DATABASE_TYPE` env var.
