Owner: a stock with a NEGATIVE overall (combined) score must not be recommended
in the profit buckets, even with positive momentum + theme. BGRIM/TTB had
combined -0.029/-0.066 yet still landed in bucket 1.
- allocate_capital profit_pool now gates on combined_score > 0 (in addition to
momentum>0 + theme>0), still ranking by momentum within that pool.
- Verified: bucket 1 now picks PTTGC (+0.209, mom +1.85) instead of BGRIM/TTB;
BANPU in bucket 2; ADVANC/SCB/LH in bucket 3 by yield. Full suite 377 green.
