Case #01 • Chronolocation & Satellite OSINT

Operation Broken Horizon: The Contested Hospital Strike

Pending Investigation

Evidentiary Intake Briefing

A state military spokesperson published an official dispatch claiming their missile forces carried out a high-precision strike at 14:15 local time (afternoon) on a militant command depot in the outskirts of Dnipro, Ukraine.

Opposition telegram channels published cellphone video alleging the missile actually struck a civilian pediatric rehabilitation clinic at 09:30 AM (morning).

Alleged Target Coordinates: 48.4647° N, 35.0462° E
Calendar Date of Incident: September 28, 2026
Key Clue: Eyewitness video shows a continuous shadow cast by a straight 8-meter lamppost onto flat asphalt pavement.

EXHIBIT 1-A: SHADOW VECTOR EPHEMERIS Observed Shadow Azimuth: 248° (Bearing West-Southwest)

Verification Question: What is the true temporal window of this recording?

Consult astronomical shadow physics: The Sun rises in the East and sets in the West. Shadows always project in the exact opposite direction ($180^\circ$ difference).

A) The 14:15 afternoon strike claim is verified.

In early autumn, afternoon sun rays in the Northern Hemisphere cast shadows pointing West-Southwest.

B) The 14:15 claim is disproven; footage was recorded during the 09:15–09:45 AM morning window.

Because the shadow projects toward the West-Southwest ($248^\circ$), the Sun was positioned in the East-Northeast ($68^\circ$), which only occurs in the morning.

C) Shadow direction is indeterminate without ground-level barometer data.

Atmospheric refractions distort shadow azimuths by more than 90 degrees.

Case #02 • Synthetic Audio & Voice Clone Forensics

The Prime Minister's Midnight Tape: The Leaked Wiretap

Pending Investigation

Evidentiary Intake Briefing

48 hours before an election, a newly created anonymous Telegram channel drops a 22-second audio memo. The voice sounds indistinguishable from the incumbent Prime Minister, discussing covert payments to sway polling officials.

The channel administrator claims the tape was recorded surreptitiously by a waiter using an iPhone at a crowded outdoor bistro.

Audio Format: 128 kbps CBR MP3 (44.1 kHz header).
Vocal Anomaly: The speaker delivers 38 continuous words without a single biological inhalation breath.
Spectrogram Finding: Acoustic energy terminates dead at precisely 16,000 Hz.

EXHIBIT 2-B: ACOUSTIC SPECTROGRAM ANALYSIS Forensic Signature: Hard Vocoder Brick-Wall Frequency Ceiling @ 16 kHz

Verification Question: Is this an authentic microphone recording or a synthetic voice clone?

Consider the acoustic properties of natural human voices recorded in outdoor environments versus neural text-to-speech vocoders (e.g. HiFi-GAN).

A) Authentic audio; the background café noise proves a physical recording location.

Ambient murmur and clinking glasses cannot be synthesized by computer speech models.

B) Synthetic voice clone; the 16kHz brick-wall ceiling and lack of respiration reveal a neural vocoder.

Real human microphones always exhibit ambient noise floors above 16 kHz; 38-word continuous phonation violates biological breathing mechanics.

C) Authentic speech recorded with a high-end vocal noise-reduction gate.

Microphone limiters routinely eliminate all frequencies above 16 kHz during recording.

Case #03 • Pixel Splicing & Error Level Analysis (ELA)

The 100,000-Citizen March: The Spliced Protest Photo

Pending Investigation

Evidentiary Intake Briefing

A protest organizer account tweeted a viral photograph claiming to show an enormous crowd in front of Parliament this afternoon holding banners reading "Resign Today: October 2026".

International wire services need to verify whether the image represents breaking news from today or a manipulated composite.

ELA Splicing Lab: The crowd and architecture display uniform dark purple compression noise, while the banner text exhibits brilliant neon white error luminance.
Metadata Inspection: EXIF records contain Photoshop history headers; IPTC date corresponds to June 2019.
Sub-Region Search: Cropping the background clock tower matches a historical celebration photograph from seven years ago.

EXHIBIT 3-C: 95% ERROR LEVEL ANALYSIS (ELA) MAP Forensic Signature: Severe Compression Differential (Spliced Text Banner)

Verification Question: What is the evidentiary verdict on this breaking photo?

Assess Error Level Analysis physics: When new elements are edited onto an existing JPEG, they undergo first-generation compression and display high error luminance relative to older surrounding pixels.

A) The photo is authentic breaking news; banner text is bright because white fabric reflects sunlight.

Optical brightness translates directly to ELA error brightness.

B) Spliced fabrication; anomalous ELA error levels and sub-region matching prove text was composited over a 2019 photo.

The banner underwent different compression cycles than the surrounding crowd, and sub-region search confirms older provenance.

C) The photo is an AI-generated image created with Midjourney.

AI images always produce bright white banner artifacts under Error Level Analysis.
