The registry keeps both identities as separate rows. A shared signal pattern does not make their meanings interchangeable.

AUDIT RESULT
A complete registry-to-row mapping
Morse Code Translator's v1 audit maps 57 declared identities to 57 output rows with zero unresolved or duplicate identity rows. It contains 55 unique dot-dash sequences and discloses two shared-sequence groups. Durations are calculations under the published timing model, not measurements of operator or device performance.

REPRODUCIBLE RELEASE
Formula, files and limits
mark units = dots + 3 × dashes
intra-character gap units = elements − 1
character units = mark units + intra-character gaps
unit ms = 1200 ÷ WPM
character duration = character units × unit ms
Scope and limitations
This release covers registry 2026-08-18.1 and standard timing only. Calculated duration is not measured audio onset, operator performance, transmission quality or an accessibility result. Farnsworth spacing, device latency, noise and safety outcomes are outside the dataset.
Version and corrections
Release v1 is immutable. A correction creates a new version and keeps prior URLs available. Send a row anchor, expected value and supporting source to support@morsecodetranslator.tools.
