iomgaa	7abe92eb1c	fix(question_gen): check_verbatim covers question_text + add missing blacklist patterns ... - check_verbatim now computes n-gram overlap for BOTH question_text and correct_option vs source texts, returning max(question_ratio, option_ratio). Extracted _ngram_overlap_ratio helper for reuse. - Added 4 missing blacklist patterns: 'this segment', 'this frame', 'the current frame', 'frame summary'. - Added 5 new test cases covering the above changes.

iomgaa	74686dde68	refactor(question_gen): reduce check_forbidden_material complexity to A(3) ... Extract _match_any helper and declarative _FORBIDDEN_MATERIAL_RULES table to replace repetitive per-category for-loops. Reduces cyclomatic complexity from C(11) to A(3).

iomgaa	c83d771923	feat(question_gen): add deterministic postprocess layer ... Add app/question_gen/postprocess.py with zero-LLM deterministic post-processing for generated questions: - shuffle_options: deterministic option permutation with answer remapping - check_referent_blacklist: detect self-referential language (this clip, etc.) - check_verbatim: word-level n-gram overlap ratio measurement - has_time_anchor: timestamp and temporal phrase detection - check_forbidden_material: T1/T7 source material validation - run_postprocess: orchestration returning PostprocessResult Tests: 31 unit tests covering all functions.
