Script Mixing policy: only emit findings when an identifier contains BOTH Basic/Extended Latin codepoints AND codepoints from a lookalike script (Cyrillic, Greek, Armenian, Georgian, Cherokee, Fullwidth Latin, Mathematical Alphanumeric). This prevents false positives on single Script identifiers.

Description density threshold: tool descriptions must contain ≥3 confusable hits before the description Level finding fires. Below that threshold we assume legitimate cross Script prose.

Evidence integrity: every `HomoglyphHit` carries the original codepoint, its position (zero Based character index), the Latin letter it impersonates, and its script block. The verification step instructs the auditor to hex Dump the raw value and confirm the codepoint — the observation is reproducible without running our detector.

Codepoint catalogue is declared once in data/invisible Codepoints.ts as a Record keyed by arbitrary stable ids (e.g. "zwsp", "bom", "bidi Embedding"). The detection logic iterates `Object.keys` on this Record — no regex, no long string Array literals.

Emoji ZWJ/VS suppression: gather.ts checks the previous and next codepoints when a ZWJ or variation Selector candidate is observed. The check uses the shared EMOJI RANGES table and is applied ONLY to descriptions (identifiers are never granted the exception).

Tag Character decoding: if a description contains three or more tag codepoints in the U+E0020–U+E007E subrange, the decoded ASCII string is surfaced in the finding as `hidden Tag Message`. The verification step shows the reviewer how to reproduce the decoding independently.

Bidi gets its own dedicated finding (critical severity) separate from the aggregated description finding, because bidi is uniquely dangerous: it produces a divergence between rendered and logical text that ordinary stripping / hex Dumping does not surface. The finding cites CVE 2021 42574 directly.
