   - In `_SCHEMA` `events` CREATE TABLE, after the `false_trigger ... DEFAULT 0,` line add: `    reviewed_real           INTEGER NOT NULL DEFAULT 0,  -- 0=no, 1=operator-confirmed real (mutually exclusive with false_trigger)`
-  - In the Migration-1 rebuild `CREATE TABLE events (...)` block, add the same `reviewed_real INTEGER NOT NULL DEFAULT 0,` line after `false_trigger`.
   - In the `_migrate` ADD COLUMN loop tuple add: `("reviewed_real", "INTEGER NOT NULL DEFAULT 0"),`
+  - **Do NOT** add it to the Migration-1 rebuild `CREATE TABLE events (...)` block — that block uses a positional `INSERT ... SELECT * FROM events_old` and, by convention, contains only the columns that existed when Migration 1 was written; every later column is added by the ADD COLUMN loop only. Adding it there crashes `_migrate` on genuinely legacy (pre-Migration-1) DBs.
 - [ ] **Step 4: Run → PASS.**
 - [ ] **Step 5: Commit** `feat(db): reviewed_real column on events (+ auto-migrate)`
