# Evidence-Locked DFIR Agent Report

This report is generated only from recorded events. It intentionally distinguishes hypotheses from verified facts.

## Executive Summary

- A suspicious email investigation was opened by a human analyst.
- Evidence was collected from email headers, attachment hash, browser timeline, and endpoint process list.
- The AI agent self-corrected an unsupported malware-execution claim.
- Human-approved containment was mailbox-only; endpoint isolation was not approved.

## Evidence Chain

- `evt-0012` 2026-05-19T12:08:12Z security-analyst: Security analyst opened a suspicious email investigation with attached endpoint telemetry.
- `evt-0013` 2026-05-19T12:08:53Z dfir-analysis-agent: Agent proposed an evidence-first DFIR plan: preserve artifacts, list hypotheses, then verify each claim.
- `evt-0014` 2026-05-19T12:09:34Z sift-collector: Collected email headers, attachment hash, browser download timeline, and endpoint process list.
- `evt-0015` 2026-05-19T12:10:15Z dfir-analysis-agent: Agent generated an initial hypothesis but flagged one claim as unsupported by current evidence.
- `evt-0016` 2026-05-19T12:10:56Z dfir-analysis-agent: System marked the draft finding as provisional because execution evidence was missing.
- `evt-0017` 2026-05-19T12:11:37Z threat-intel-api: Hash lookup returned low-confidence phishing kit association; raw indicator was redacted in report output.
- `evt-0018` 2026-05-19T12:12:18Z security-analyst: Human approved containment of the reported message and requested no endpoint isolation.
- `evt-0019` 2026-05-19T12:12:59Z agentops-recorder: Generated DFIR report with evidence IDs, unsupported claims, and human containment decision.

## Hypotheses And Status

| Hypothesis | Status | Evidence |
|---|---|---|
| The email is a phishing attempt. | Supported at low-to-medium confidence. | `evt-0014`, `evt-0017` |
| Malware executed on the endpoint. | Not supported by current evidence. | `evt-0015`, `evt-0016` |
| Mailbox-only containment is enough for this case. | Human-approved decision. | `evt-0018` |

## Analyst Guardrail

The agent may suggest hypotheses, but the final report must cite event IDs and mark unsupported claims instead of presenting them as fact.
