Reproduces the off-by-one misalignment bug.
|
||||
|
||||
Scenario:
|
||||
1. HTML contains: [Para1], [Nav], [Para2]
|
||||
2. Ordered IDs passed to builder: [ID1, ID2] (assuming Nav is validly ignored by extractor logic but maybe ID list is different?
|
||||
Actually, let's trace the bug logic:
|
||||
Extractor:
|
||||
- Para1 -> Clean -> Valid -> Added to Manifest (Status: Pending) -> ID1
|
||||
- Nav -> Clean -> Valid -> Added to Manifest (Status: Ignored) -> ID2
|
||||
- Para2 -> Clean -> Valid -> Added to Manifest (Status: Pending) -> ID3
|
||||
|
||||
Builder Input:
|
||||
- translation_map: {ID1: "Trans1", ID3: "Trans3"} (Nav ignored so no trans)
|
||||
- paragraph_map: {ID1: ..., ID2: ..., ID3: ...}
|
||||
- ordered_ids: [ID1, ID2, ID3] (All items in file)
|
||||
|
||||
Builder Loop (Current Broken Logic):
|
||||
- Scans Para1: Valid, Not Nav.
|
||||
- Match with ordered_ids[0] (ID1). OK.
|
||||
- Incr index -> 1.
|
||||
- Scans Nav: is_navigation_element() == True -> CONTINUE
|
||||
- Index remains 1.
|
||||
- Scans Para2: Valid, Not Nav.
|
||||
- Match with ordered_ids[1] (ID2).
|
||||
- ID2 is the Nav item!
|
||||
- translation_map.get(ID2) -> None (or wrong if ID2 had a translation).
|
||||
- Result: Para2 gets NO translation or WRONG translation.
|
||||
- Expected: Para2 should match ID3.
