CRONOS Audit Trail
Trace
Objective
Analyze CASE VIGIA-OPENCODE-001 — 'Evidence for cause' — to determine if evidence against Marcos R. is genuine or fabricated, assign verdict (SILENT / SUSPICION / MALICE) with capped score, and provide actionable HR recommendation.
Step-by-step trace
Analyze CASE VIGIA-OPENCODE-001 — 'Evidence for cause' — to determine if evidence against Marcos R. is genuine or fabricated, assign verdict (SILENT / SUSPICION / MALICE) with capped score, and provide actionable HR recommendation.
genuine_leak2026-07-19T00:46:21.005659+00:00Marcos R. did leak the database; the submitted artifacts are authentic and unaltered.
fabricated_evidence2026-07-19T00:46:22.732364+00:00The evidence was fabricated by D. Herrera to discredit Marcos R., leveraging his managerial access and knowledge of forensic gaps.
inadvertent_error2026-07-19T00:46:24.442585+00:00The anomalies in the artifacts are due to accidental misexport, tool misuse, or misconfiguration — not intentional fabrication.
PNG screenshot shows ELA compression discontinuity around message bubble and timestamp, inconsistent with rest of image.
PDF 'email export' has Producer = 'Adobe Photoshop 25.0', CreationDate 6 days after incident, and mismatched fonts (Helvetica in To:, Arial in body).
DLP log row (event_id 48213) is out-of-sequence and its integrity hash does not chain with adjacent rows.
Acquisition-chain prior_trust = 0.4: no device imaging, no write-blocker, no hashes at collection time; artifacts handed in by interested party (D. Herrera) with documented salary/promotion dispute.
genuine_leak2026-07-19T00:46:38.522976+00:00Refuted by low acquisition-chain trust (0.4) and multiple digital anomalies across all three artifacts — inconsistent with authentic chain-of-custody evidence.
inadvertent_error2026-07-19T00:46:40.471430+00:00Refuted by the confluence of three independent fabrication signatures: ELA discontinuity + Photoshop metadata + DLP hash break — too numerous and tool-specific to be accidental.
VERDICT: MALICE — evidence was deliberately fabricated by D. Herrera. However, the acquisition-chain prior_trust of 0.4 caps the final score at SUSPICION (65/100).
