Security incident timeline construction agent blueprint.
Order normalized event evidence, label confidence, and prepare a reviewable incident chronology without altering source logs.

01 · the contract
Start from a bounded job, not a blank chat box.
trigger
A security incident requires a consolidated chronology.
owner
security owner
agent stops at
The incident lead approves the chronology before external or executive distribution.
KPI · decrease
timeline revision count (revisions). Count material chronology corrections after incident-lead approval.
outputs
Artifacts the run must produce
- Timestamped incident timeline
- Confidence and evidence map
- Open investigative questions
02 · topology
Small specialists. Named handoffs. One accountable decision.
Each stage produces an artifact another stage can inspect. The final node is a person, not an autonomous write to an external system.
- 01
intake
Validate and normalize the security incident timeline construction inputs.
- 02
event normalizer
Produce the timestamped incident timeline.
- 03
timeline correlator
Produce the confidence and evidence map.
- 04
forensic reviewer
Challenge the security incident timeline construction result and prepare an approval packet.
- 05

03 · authority
Grant the run only what this case needs.
Source material is read-only. Drafts land in a case-specific output path. Tools may read or propose; the human gate owns the external write.
case inputs
workspace/security/incident-timeline-construction/inputs/**Read only the evidence attached to this workflow instance.
case outputs
workspace/security/incident-timeline-construction/outputs/**Write drafts and evidence artifacts without modifying source records.
approved tools
security:incident-timeline-construction:read-or-proposeInvoke only tools explicitly granted for this run; external writes remain gated.
04 · implementation
A private, bounded starting manifest.
The blueprint starts private, caps its DAG, disables replanning, and exposes no public endpoint. Add only the tools and data adapters this workflow has approved.

Evidence traceability
Every material conclusion cites an input artifact or a scoped tool result from this run.
- 02
Every event keeps its source timestamp, source reference, normalization note, and confidence level.
Every event keeps its source timestamp, source reference, normalization note, and confidence level.
- 03
Approval boundary
The run stops at a proposal and records the human decision before any external side effect.
failure containment
Stop small. Preserve the evidence.
Clock skew or missing identifiers prevents reliable event correlation.
Containment: Return a partial result with unresolved items; do not broaden scope or perform an external write.
Operator: Attach the missing evidence, narrow the brief, or explicitly approve a new scoped run.
A required input or tool grant is unavailable.
Containment: Stop the affected branch and preserve completed artifacts in the case output workspace.
Operator: Grant only the missing resource or continue with that branch marked out of scope.
06 · proof
Sign the run facts. Keep money in the billing ledger.
Current platform receipts sign caller identity or classification, skill, bounded input evidence, verified grant IDs when present, outcome or result preview, and timing. Optional file, tool, artifact, handoff, evaluation, and review fields require separate instrumentation and are not populated by default. Price, fees, payouts, and later human approvals remain separate platform records.
The example uses only fields populated by the current platform sealing paths. It is illustrative, not a record of a real customer run.

Combine scanner evidence, asset context, exploitability signals, and compensating controls into a reviewed priority decision.

Secrets exposure response
Build an exposure timeline, affected-resource list, and rotation plan without copying secret values into artifacts.

Normalize account and entitlement exports, flag anomalous access, and produce a reviewer-ready certification packet.
put the pattern to work
Start private. Scope the authority. Require the decision.
Deploy the workflow as a bounded internal agent, verify its outputs and the receipt fields actually emitted, then expand only the scopes your acceptance test proves it needs.
