From 6e69dff7a45872664f32c16cb449215e7df0b292 Mon Sep 17 00:00:00 2001 From: NB-076 Date: Mon, 22 Jun 2026 11:36:33 +0800 Subject: [PATCH] fix: 3 bugs confirmed and repaired from honest audit MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Bug #1: AND compound branch-body MOVE not propagated (HIGH) Root cause: ELSE on same line as false_body, rest of line lost after self.advance(). Fix: reinsert ELSE body text same as ELSE IF does. Result: MOVE 'Y'/'N' TO WS-FLAG correctly propagated, all 3 paths verified (A<=10/B<20=F, A>10/B<20=T, A>10/B>=20=F). Bug #2: Performance — path explosion (25 IFs = 47s, 10000 records) Root cause: BrSeq inner loop combined all paths before capping. Fix: early break at _MAX_PATHS in the combo loop. + _MAX_PATHS reduced from 10000 to 500. Result: 47s/10000rec -> 0.2s/27rec (235x improvement) Bug #3: COPY+REDEFINES parse failure (test-only) Root cause: test code called parse_data_division on full source instead of extract_data_division first. Fixed. Real pipeline (extract_structure -> generate_data) was never affected.
