Subject: FORMAL NOTICE: Staged Test Environment & Active
Suppression of Evidence — Claim #42647461

ATTENTION: WorkSafeBC Case Management and Arcose
Consulting Group,

lam writing to formally notify all parties that Report ID: 2044-
20260306 (Project No. 2044.20383.2026) is fundamentally flawed,
based on a staged test environment, and reflects a deliberate
suppression of forensic data.

As a 25-year heavy industry professional with an honors-level
technical background (3.73 GPA, NAIT), | am submitting the following
Evidence of Administrative and Regulatory Non-Compliance:

1. ACTIVE SUPPRESSION OF THE JAN 29 FORENSIC BRIEF The
attached Acoustic Trauma Brief was filed on January 29, 2026, as
part of my formal WorkSafeBC Unsafe Workplace Report.
WorkSafeBC and the Employer failed to provide this brief to the
Arcose investigators. By withholding this forensic data, the Board
ensured the survey would ignore the documented 328Hz narrow-

band resonance ("Acoustic Laser") that caused my injury.
