Three-Claim Trace — finding → tool execution → evidence

The rules guarantee a judge "must be able to trace any finding back to the specific tool execution that produced it." This walks three findings from the headline 100% run end to end, using only the committed logs in execution_logs/gpt55_100pct_run/.

Every claim traces through the same chain:

finding (findings.json, observation O-NNN)
  └─ cites record_id R + verbatim span_text  ← citation gate enforced span ⊆ record
       └─ R was surfaced to the agent by a query tool call  (index.jsonl: audit_id + query + hits)
            └─ R was produced by the offline ingest          (record.audit_id = sift-phase9-20260615-002)
                 └─ from a source artifact on the read-only image (artifact_path + sha256)

index.jsonl = the agent's tool executions (timestamped, with audit_id); findings.json = the recorded observations; the ingest audit_id ties each index row to the extraction that created it.

Claim 1 — Q4 (how): privileged-account brute force

• Finding: observation O-001 — failed-logon brute force against admin/backup accounts.
• Cited record: record_id 2514145, span "SIGMA DETECTION level=medium rule=Failed Logon Attempt … event_id=4625 …".
• Tool execution that produced it: list_detections (audit sift-analyst-20260615-102) returned the staged Sigma alerts (total 542,704 detections), and search_evidence (audit sift-analyst-20260615-014, query 4625 OR "EventID=4625", 50 hits) pulled the specific failed-logon records.
• Self-correction touchpoint: the live critic returned AGREE on O-001 (critic.jsonl), confirming the cited 4625 records support the claim.

Claim 2 — Q2 (what was taken): the stolen SRL R&D projects

• Finding: observation O-003 — Stark Research Labs project files were accessed/collected.
• Cited record: record_id 2514417, span "LNK target=C:\Users\fredr\Stark Research Labs\SRL-Projects - Airwolf" (siblings cite SRL-Projects - Gunstar, Blue Thunder, and an F:\Key Data collection folder).
• Tool execution that produced it: search_evidence (audit sift-analyst-20260615-209, query "SRL-Projects", 20 hits) surfaced the Recent-folder LNK rows — produced by the LNK feeder during ingest.
• Self-correction touchpoint: critic AGREE on O-003 — the LNK targets directly name the SRL project folders.

Claim 3 — Q3 (where it went): exfiltration to Google Drive + PST email export

• Finding: observation O-004 — SRL data staged to cloud sync / exported as PST.
• Cited record: record_id 2514416, span "LNK target=G:\My Drive\STARK-RESEARCH-LABS FOLDER\Exported-PST\SRL-EMAIL-EXPORT…".
• Tool executions that produced it: search_evidence (audit sift-analyst-20260615-117, query OneDrive OR Dropbox OR GoogleDriveFS OR rclone OR ftp, 20 hits) found the cloud-sync paths; a follow-up search_evidence (audit sift-analyst-20260615-211, query "LNK target=G:\My Drive\STARK-RESEARCH-LABS FOLDER") confirmed the G:\My Drive (Google Drive) staging location.
• Self-correction touchpoint: critic CHALLENGE on O-004 — it pushed back on an over-broad exfil claim; the investigator revised it (see O-007: "This revised interpretation follows the critic guidance"). This is a genuine challenge → revise loop.
