Audit prep in minutes,
not weeks.
Structural proof, file:line citations.

5 weeks. 8 engineers. 200 spreadsheets.

Every regulated SaaS team runs the same fire drill four times a year: SOC 2 surveillance, HIPAA risk assessment, PCI-DSS attestation, and the annual SOX 404 walkthrough. The auditor sends a Request For Evidence with 50-200 controls. For each one, an engineering lead has to prove — not just attest — that the code actually does what the policy says it does.

Today that proof is grep + Excel + Confluence. Engineering teams burn ~$50K per audit cycle in human time alone, and the artifacts produced are spreadsheets the next auditor distrusts on sight. HIPAA fines reach $2M per violation. PCI-DSS non-compliance costs $25K-$100K per month. FedRAMP delays push contracts back two quarters. The math punishes the unprepared.

"The auditor wanted to see every place a SSN touches a log emitter across 1.4M lines of TypeScript. We had two weeks. The team grep-walked it for 8 days, missed three sites, and the auditor caught two of them anyway. Embarrassing."
— VP Engineering, healthcare SaaS (anonymized, post-HIPAA Type II)

Five steps. Two hundred hours. One panic week.

1. Receive the auditor's Request For Evidence. 50-200 controls. Each requires "show me the code paths."
2. Per control, do a manual data-lineage hunt. Grep PII / cardholder / PHI keywords. Open 5-15 files. Trace callers by hand. 30-60 min per finding.
3. Spreadsheet column "Where it flows". Per control: 30-60 minutes of file-walking. Per audit: ~200 hours total.
4. Build the evidence pack in Word + Confluence. Screenshots of code, copy-pasted file paths, narrative paragraphs. Auditor reads it and asks for follow-ups anyway because evidence isn't reproducible.
5. Result: 5 weeks of senior eng time burned. 12% miss rate on data flow paths (auditor catches the rest). Same exact work next quarter, same exact spreadsheet rebuilt from scratch.

Math per audit cycle: 200h × $250/h = $50K of human triage time. Four audits per year = $200K/year on top of the GRC-platform license ($60K-$120K) and the auditor's invoice ($80K-$300K). The artifacts produced have negative shelf life — next quarter, you start over.

EVIDENCE PACK
  reproducible: yes (deterministic over canonical AST hash)
  file:line citations: 47
  call-graph paths: 47
  ingest hash: blake3:9f2c...8b1a
  framework tags: PCI-DSS 3.4, SOC 2 CC6.7, HIPAA §164.312(c)(2)
  cloud calls: 0 · LLM calls: 0 · audit-friendly: yes

Two findings to fix. 45 controls auto-attested with structural proof. The evidence pack is byte-reproducible, hash-stamped, and accepted as-is by AICPA, HHS OCR, and PCI Council assessors. Re-run on every CI build to catch regressions before the auditor does.

The math for one audit cycle.

Numbers measured against the Kubernetes 1.32.0 corpus (17,171 files, 38,771 symbols, 232,756 edges). See the Kubernetes audit case study for the full reproducible run.

Auditor-grade evidence, multi-framework, on a CI clock.

• HIPAA Security Rule — §164.308 administrative safeguards (access-control walkthroughs), §164.312(a) technical safeguards (encryption-at-rest reachability), §164.312(c)(2) integrity (no PHI flows to unmasked sinks).
• SOC 2 Type II — CC6 access (RBAC uniformity per endpoint), CC6.7 input validation (CSRF coverage on state-changing routes), CC7 system operations (incident response data flow).
• PCI-DSS 4.0 — §3.4 PAN masking, §6 secure code (sink-to-source reachability for SQLi / XSS / SSRF), §10 audit logging (every payment-flow path emits to centralized logger).
• FedRAMP Moderate / High — air-gapped deployment, no telemetry, no LLM in the retrieval path, evidence packs that satisfy 3PAO assessor expectations.
• SOX § 404 IT general controls — change management proof (git-blame integrated), authorization controls (per-endpoint RBAC matrix), data integrity (financial-data sink reachability).
• Reproducible evidence — every claim hashed, byte-identical re-runs, file:line citations, deterministic call-graph paths. No LLM, no stochasticity, no "the model said it was fine".
• Complementary to Drata, Vanta, SecureFrame — they track policy attestation, we prove implementation. Most regulated teams export ArgosBrain evidence packs into their GRC platform.
• Pairs with /anti-sast — same engine. SAST findings get reachability proofs; compliance controls get data-flow proofs. One ingest, two audits.
