  "corpus": "lv-bronte (Charlotte Brontë — Jane Eyre, Villette, Shirley, The Professor)",
  "why": "The unigram rename cannot reach an in-world compound built out of ordinary words, and it cannot reach a character whose given name is also an English noun. Both classes survive a gate that reads 0 of 203, for the same reason `Riders Quadrant` and `Fourth Wing` survived Yarros's: the cap/lowercase detector correctly refuses to call `Moor`, `Marsh`, `Vale` or `Grace` a name, so rename never sees them.",
  "how_derived": "Measured, not guessed. Every capitalised 2-3gram recurring >= 5 times in the source (88 of them) was checked component-by-component against the renameable entity set; only the 5 whose EVERY component is non-renameable survive the rename verbatim, and those are the `phrases` below. The `tokens` are the two characters the ratio test drops and one given name the compound pass leaves bare. Every replacement was collision-checked against the whole corpus and occurs 0 times in it.",
  "phrases": {
    "Moor House": "Ashdene House",
    "Marsh End": "Thurlby End",
    "Vale Hall": "Kelmar Hall",
    "Bigben Close": "Denholm Close",
    "Royd Lane": "Crowmoor Lane"

  "tokens": {
    "Blanche": "Rosalind",
    "Grace": "Millicent",
    "Matthewson": "Everard",
    "Hollow": "Sowerby"
  },
  "tokens_why": "`Blanche` (Blanche Ingram) has 19 capitalised occurrences against ONE lowercase, giving ratio 0.0526 — over the 0.05 bar by a single token, so a named character with 19 mentions is dropped by a hair. `Grace` (Grace Poole) is rejected honestly: `grace` the common noun runs at a 0.224 lowercase ratio in Jane Eyre. Sampling all 21 bare capitalised `Grace` found 20 are the character in direct address (`Too much noise, Grace`, `Good morning, Grace`) and exactly one is the theological noun (`children of Grace`), which this map will also substitute — a known and accepted cost of one occurrence against a character leaking 37 times. `Matthewson` is Rev. Helstone's given name; the surname renames, the given name does not. `Hollow` (Hollow's Mill, and `the Hollow` for the valley) is 85 capitalised against 20 genuinely lowercase (`rushing down the hollow`), ratio 0.235 — the detector refuses it correctly. The token map is capitalised-and-whole-word, so it reaches `Hollow’s Mill` and `Hollow’s Miln` without touching the common noun. Caught only because a positive control asserted `Hollow` should be an entity and the gate disagreed; the control was wrong, not the detector — the same way `Adèle` failed as `Adele`.",
  "allow": [
    "Good God",
    "Thank God",
    "Lord Wellington",
    "Human Justice",
    "Miss Smith",
    "And Mrs"
  ],
  "allow_why": "Real-world referents and generic English any novelist could write. `Lord Wellington` is the historical commander (Shirley is set during the Napoleonic wars). `Human Justice` is an allegorical personification in Villette built from two ordinary nouns. `Miss Smith` is the most generic surname in English and belongs to a minor Lowood teacher. `Good God` and `Thank God` are exclamations. `And Mrs` is a regex artefact of the audit's own 2-3gram pattern catching a sentence-initial `And Mrs.`, not a name.",
  "deliberately_NOT_mapped": "`Rue Fossette`, `Thornfield Hall`, `Crimsworth Hall`, `Walden Hall`, `Sympson Grove`, `Nunnely Common`, `Grace Poole`, `Jean Baptiste`, `Meess Lucie`, `Cyril Hall` and `Margaret Hall` all LOOK like leaks in the audit listing and are not: each has at least one renameable component, so the phrase never survives verbatim into a copy. Mapping them would be double-substitution. `Moor` is mapped only inside `Moor House` — bare `Moor` is the Yorkshire moorland and renaming it would damage the prose for no leak benefit."
