+-- Import-mode companies (gl_auto_post=false) get their GL from the Buildium pull,
+-- so locally-entered bank transactions never reached the GL and were invisible on
+-- GL-based reports (P&L, Income Statement, Balance Sheet) even though they
+-- reconciled. This lets those manual transactions post to the GL.
+--
+-- A transaction posts UNLESS it is: voided; sourced from the Buildium GL pull
+-- (journal_entry_line_id set — would double-count); explicitly excluded
+-- (exclude_from_gl — used to freeze pre-existing manual/duplicate register rows on
+-- already-tied books so they don't double-post if later edited); a transfer/deposit
+-- leg (handled by post_transfer_gl / post_deposit_gl); or missing an account/counter.
+--
+-- One-time data ops applied alongside this migration (not repeatable, so kept out
+-- of the migration body): (a) linked every Buildium-sourced register row to its GL
+-- bank line via (account,date,direction,amount) matching; (b) set
+-- exclude_from_gl=true on all remaining pre-existing unlinked manual rows for
+-- import companies EXCEPT Bent Oak; (c) posted Bent Oak's 4 verified-missing
+-- operating rows (interest/insurance/electric/water-fee).
