Undated Broadcasts Identified: Five Minute Mysteries and 4

Undated Broadcasts Project — The 4,900-Broadcast Milestone Reached

With the completion of This update, the Master Undated Broadcast Resolution Pipeline has officially crossed the monumental 4,900-Broadcast Resolution Milestone, bringing the cumulative project total to 4,923 verified broadcasts resolved across 103 completed updates.

Continuing our sequential restoration of the classic crime puzzle feature Five Minute Mysteries (d0da018b-4e33-4985-80f4-9933b6ca0cf8), this update resolves an additional 50 sequential syndication broadcasts (Episodes 63 through 112).

Syndicated nationally on transcription discs by the Frederic W. Ziv Company from May 9, 1949 through April 17, 1950, this sequence challenges listeners to spot the critical forensic contradiction before Inspector James reveals the fatal flaw in the suspect's story:

• Forensic Chemistry & Technical Alibis (Episodes 63–87): Highlights include "The Partners aka The Sprinkler Clue" (staged warehouse blaze debunked by thermal sprinkler pipe activation order), "Locale - Tibet" (high-altitude atmospheric pressure and freezing rates disproving a fabricated timeline), "Radium Murder Case" (early atomic-era industrial radioactive isotope exposure), and "Air Raid aka The Blackout Murder" (civilian blackout drill manipulated for homicide).
• Physical Clues & Auditory Puzzles (Episodes 88–112): Inspector James investigates optical and behavioral inconsistencies in "In Reverse aka The Mirror Murder" (reflection angles and inverted text), "Signal Block aka Death On A Train" (railroad semaphore block logic), and "Clue Of The Drinking Dog aka Mr. Daily's Fake Robbery" (canine behavioral forensics exposing staged insurance fraud).

Direct Audio Transcription & Provenance Rigor

Adhering strictly to our core archival standard and the empirical principles established in our foundational paper, "Dating the Undated: Newspaper Radio Logs as Primary Evidence for a Quarter-Million Broadcast Recordings" (Radio Index, 2026):

• Surviving transcription discs are directly transcribed using Whisper SPEECH RECOGNITION, generating synchronized WebVTT subtitle manifests and grounding synopses in spoken dialogue with whisper:<sha256> provenance.
• In strict adherence to our no invented details mandate, broadcasts lacking verified audio streams remain completely free of synthetic descriptions or hallucinated details, preserving discographic truth across the catalog.

Reaching 4,923 broadcasts resolved across the master project ledger, each entry features verified weekly syndication airdates, standardized Mystery/Crime Drama taxonomy, and authentic syndicator credits.
