false ⇒ attacker-authored arbitrary text (the txt→b64url fallback): a
near-collision can be crafted cheaply, so sampling is unsound and the plan
reads in full (§15.4). Conservative heuristic — the tool cannot observe
generation (a recognized encoding is assumed constrained; only the
no-parser-claimed fallback is treated as programmable), matching §7.3's
"credit 0 for non-locally-generated" framing.
filledCells
filledCells:number
count of filled (non-blank) cells.
homoglyphProne
homoglyphProne:boolean
the alphabet is confusable-prone (base64 / base64url): §14.5 adds one extra
read cell to a sampled plan to offset homoglyph erosion over voice.
