Per the CLAUDE.md operating manual, this is one of three approving leaders alongside the CFO and COO. Not named in the corpus. This is a pre-meeting cheat sheet, not an architecture review. ## Decision frame (the three numbers) | | Value | Source | |---|---|---| | **Test results** | 9,038/9,061 passing (23 intentionally skipped) | [[sources/11-role-brief-cto]], [[sources/01-executive-summary]] | | **AI accuracy** | 95%+ | [[sources/11-role-brief-cto]] | | **Governance evidence** | Available in dashboard flows | [[sources/11-role-brief-cto]] | > The 9,038/9,061 numbers are the **slide-vintage** snapshot used throughout the executive package — not the current Preston-Test repo state (9,364/9,394). See [[pages/concepts/production-proof]] for the historical-evidence framing. ## What the CTO should validate (the three asks) Before approval: 1. **Production behavior via watch clips.** Demo videos showing the system running in production-like conditions. The CTO should *actually watch* these — not take "production-ready" as an article of faith. The asset library is presumably catalogued in `NOTEBOOKLM-ASSET-MAP.md` (not yet ingested). 2. **Compliance evidence export and SOC 2 Trust Services Criteria mapping.** The system can produce exportable compliance evidence and maps its controls specifically to the **SOC 2 Trust Services Criteria** framework (per [[sources/read-elevator-pitch]] Beat 3 — *"A compliance dashboard mapped to SOC 2 Trust Services Criteria"*). TSC is the specific SOC 2 control framework with five trust categories (Security, Availability, Processing Integrity, Confidentiality, Privacy). This is now two-source confirmed ([[sources/11-role-brief-cto]] originally; [[sources/read-elevator-pitch]] added the TSC specificity). The CTO should still ask to see the actual SOC 2 TSC control mapping document, not a summary of one — two sources confirming a claim is not the same as verifying the document exists and is complete. 3. **Failure-path visibility and fallback handling.** When something breaks, can the CTO see *what* broke and *what* the system did about it? This is the multi-provider AI fallback claim from [[sources/01-executive-summary]] reframed as an inspectable system property: don't trust that fallback exists, look at the traces. 4. **Verify the four named enterprise safety mechanisms.** Per [[sources/ai-governance-layer-video]] (02:06-02:22), SuiteCentral 2.0's governance layer is built from four specific components. The CTO should validate each one is actually shipping, not just on a roadmap: - **Reasoning Trace Engine** — logs justifications for every AI decision. Verify the log is persisted (per [[sources/read-elevator-pitch]]: *"Reasoning traces persisted to database"*) and queryable. - **Governance Pacer** — prevents throttling. Verify it actually respects NetSuite API concurrency limits under load (not just in the happy path). See [[pages/entities/reuben-cook]] for Reuben's architecture angle on this. - **DLP PII Shield** — redacts sensitive data. Verify the redaction catches the classes of PII Squire's clients care about (SSN, account numbers, names, addresses, etc.). - **Approved To Apply** — cryptographic verification of human sign-off. Verify the cryptographic primitive is real (signed with a real key, auditable to a named approver) and not just a checkbox. ## Why this framing works for a CTO - It respects the CTO's job: confirm the technology works *and* fails safely before letting it touch production data. - The asks are all **artifacts the CTO can independently evaluate**, not vendor claims. Watch clips, exports, traces — none of them require Squire to take engineering's word for it. - The 95%+ AI accuracy number is anchored without overclaiming. "95%+" leaves headroom and acknowledges that AI is not deterministic. - The brief does not pre-digest the technical proof for the CTO. It assumes they can evaluate the artifacts themselves. ## What the CTO should ask for (open questions in the corpus) - **The 95%+ accuracy methodology.** Which task is being measured? On which dataset? Using which evaluation harness? Not in this source. Flag `04-TECHNICAL-PROOF.md` and `AI Provider System Documentation` for ingest — both are in the notebook. - **The SOC2 mapping document itself.** For a CPA firm, this is non-negotiable. The brief claims the mapping exists; the CTO needs to see the actual document and verify which controls are mapped and how completely. - **The 23 skipped tests.** What are they, why are they skipped, are they blocking? Already an open question on [[pages/concepts/production-proof]]. - **Coverage gap analysis.** The Preston-Test `README.md` reports 64.48% statement coverage — 35%+ uncovered. Which subsystems? (Open question on [[pages/concepts/production-proof]].) - **Watch clip catalog.** Where are they, who recorded them, when? ## Cross-role context The CTO brief is one of three role briefs in the executive package — see [[pages/role-briefs/cfo|CFO brief]] and [[pages/role-briefs/coo|COO brief]]. In the live demo flow they appear as a **parallel choice in step 6 of Path B** (the leadership review path) — each reviewer reads the brief that matches their job rather than reading all three. See [[pages/concepts/three-review-paths|Path B]] for the full sequence. The three briefs do divide the decision concerns cleanly. The CTO's specific contribution is *correctness and safety* — the CFO has the cost story and the COO has the throughput story; the CTO is the only one who can veto on engineering grounds. For one specific case — a reader who must reconcile all three perspectives, like the CEO of Squire & Company — see [[pages/synthesis/three-role-decision-frame|The Three-Role Decision Frame]] for the cross-role reconciliation view. ## Sources - [[sources/11-role-brief-cto]] — primary source, all six claims - [[sources/01-executive-summary]] — claim 2 (test counts), independently confirmed - [[sources/15-start-here-async-standalone]] — confirms the role briefs appear as step 6 of Path B as a parallel choice (corrected the original "read together" framing) - [[sources/read-elevator-pitch]] — claim 9 (SOC 2 Trust Services Criteria framework specificity; previously the SOC 2 claim was single-source and generic) - [[sources/ai-governance-layer-video]] — claim 15 (the four named enterprise safety mechanisms: Reasoning Trace Engine, Governance Pacer, DLP PII Shield, Approved To Apply) - [[sources/13-pilot-30-60-90]] — Gate Metric 4 "Governance: evidence package exported and reviewed" + confirms that compliance/evidence export checks run weekly during the Day 31-60 Controlled Execution phase, not just at Day 90
