8:14 a.m. Tuesday in Dallas. The Dallas commercial-property underwriter opens the Acme Warehousing Inc. submission packet: ACORD 125 with named insured Acme Warehousing Inc. at 4720 Industrial Blvd Dallas TX 75247, FEIN 75-3xxxxxx, NAICS 493110 (General Warehousing and Storage), broker Roper-Smith Insurance Brokers, Plano TX. ACORD 140 with 47 locations across 12 Dallas-Fort Worth Metroplex ZIPs. SOV with $182M TIV across the 47 buildings, three locations above $25M ($26.4M Carrollton, $31.8M Mesquite, $48.2M Grand Prairie). 5-year loss run with two non-cat fire losses ($142K and $87K incurred, 2022 and 2024) and four wind-related losses ($14K-$61K, two in 2022 and two in 2024). COPE narrative attached describing protection, sprinkler coverage, central station alarm status per location. Treaty schedule shows $25M single-risk facultative cession threshold; the carrier's cat aggregate is 78% consumed for the quarter. Carrier appetite guide declines class 1 (frame) habitational in coastal counties; quotes class 5 light non-combustible with restrictions; binds class 6 fire-resistive standard. The producer has flagged three buildings as habitational frame appetite exception - buildings 14, 27, 41 - and is requesting bind with documented analysis. The underwriter has 47 minutes before her next submission and a quarterly portfolio-review with the chief underwriting officer at 11:00. The L2 task: produce a Cytora-style triage memo with per-building appetite map, knockout reasons, treaty-cession recommendations, missing-info requests, and reason-code memo - in the format that drops into Federato as a structured submission record. This lesson walks the full triage with prompt, output, and verification.

The Triage Prompt Against the Acme Packet

Apply the L2 Lesson 1 architecture and the L2 Lesson 2 constraint posture. The system message names the underwriter's role and the §4 discipline; the user message loads the ACORD 125 + 140 + SOV + loss run + COPE narrative + appetite guide + treaty schedule as context; the artifact is the Cytora triage memo with 12 sections; the constraints prevent the five failure modes (named-insured paraphrase, TIV summation drift, roof-age fabrication, ISO endorsement-number fabrication, loss-run severity narrative invention).

System message. "You are a licensed P&C underwriter in the commercial-property line at a regional admitted carrier writing in TX, OK, AR, LA, MS, NM. NAIC Model Bulletin §4 reason-chain discipline applies. Cite policy forms by exact edition. Every adverse-decision recommendation must enumerate variables and flag protected-class proxies. Do not invent ISO codes, NCCI codes, carrier appetite specifics, or loss-run details. Do not paraphrase the named-insured address. Do not compute TIV totals - quote from SOV. Do not fabricate roof age. Texas DOI Bulletin B-2024-3 governs geographic underwriting in Brazoria + adjacent Tier 1 wind counties; that bulletin's protected-class-proxy framework applies."

User message (excerpt). "Triage the Acme Warehousing Inc. submission for the Dallas UW desk. Context: ACORD 125 attached; ACORD 140 attached (47 locations, ISO construction codes per location, sprinklers/alarms per location, protection class per location); SOV attached ($182M TIV, three locations above $25M at $26.4M, $31.8M, $48.2M); 5-year loss run attached (two non-cat fire 2022 + 2024 with $142K and $87K incurred; four wind 2022 + 2024 at $14K-$61K); COPE narrative attached; FEMA NRI per location loaded via RAG; EagleView roof age per address loaded via RAG (32 of 47 locations covered; 15 do not). Carrier appetite guide loaded via RAG (current version v2026-04). Treaty schedule: $25M single-risk facultative threshold; cat aggregate 78% consumed for Q2. Producer flagged buildings 14, 27, 41 as habitational frame appetite exception; producer requests bind with analysis. Artifact: Cytora triage memo with (1) overall appetite recommendation; (2) per-building appetite map covering all 47 locations; (3) treaty-cession recommendation for the three locations above $25M; (4) cat-aggregate impact summary; (5) habitational-frame analysis for buildings 14, 27, 41 with knockout reasons or quote-with-restriction path; (6) missing-information requests covering the 15 locations without EagleView and any other gaps; (7) §4 reason-code memo enumerating variables for adverse recommendations and flagging protected-class proxies; (8) producer outreach script; (9) verification flags. Format: structured headings, per-location tables, bullet-list missing-info, length 1,500-2,200 words."

Output expected - partial. Overall: refer with conditional quote-with-restriction on buildings 14, 27, 41 + facultative cession on Carrollton + Mesquite + Grand Prairie. Per-building map: 44 of 47 in-appetite (class 5 light non-combustible standard); 3 (buildings 14, 27, 41) on habitational frame appetite exception. Treaty cession: facultative cession recommended on Carrollton ($26.4M - $1.4M above retention), Mesquite ($31.8M - $6.8M above retention), Grand Prairie ($48.2M - $23.2M above retention with surplus-treaty layer involvement). Cat aggregate: account's wind PML adds 0.8 points to the 78% consumed posture, pushing aggregate to 78.8% - within tolerance but flagged for portfolio-review attention.

The Habitational Frame Exception Analysis on Buildings 14, 27, 41

The three buildings on appetite exception are the underwriter's highest-leverage analytical surface. The producer has framed them as habitational frame in non-coastal Dallas-county locations (not Tier 1 wind), which is the appetite-exception path the carrier has documented. The L2 prompt produces the analysis with structured output.

Building 14 - 18-unit residential rental, 4,200 sq ft, ISO class 1 (frame), Mesquite TX 75150. Construction year 1978; year-built data carries from ACORD 140. EagleView confirms roof age 12 years (replaced 2014). Sprinklered Y (full coverage per COPE narrative). Central station alarm Y. Protection class 4. Distance-to-hydrant 350 ft. Distance-to-fire-station 0.6 miles. 5-year loss history clean. Appetite analysis: class 1 frame habitational outside Tier 1 wind, sprinklered, alarmed, clean losses - fits appetite exception criteria. Quote-with-restriction recommendation: $50K AOP deductible, 3% Named-Storm deductible, 80% co-insurance, roof-age exclusion not applied (roof under 15 years), water-backup endorsement available at $5K sublimit.

Building 27 - 22-unit residential rental, 5,100 sq ft, ISO class 1 (frame), Carrollton TX 75007. Construction year 1984. EagleView: no data (one of the 15 uncovered locations). Sprinklered Y. Central station alarm Y. Protection class 3. Distance-to-hydrant 280 ft. Clean loss history. Appetite analysis: same fit as Building 14 except for missing roof-age. Recommendation: quote-with-restriction conditional on producer providing roof inspection report; if roof age >15 years, roof-age exclusion applies; if roof age <=15 years, standard appetite-exception quote applies. Missing-info request issued to producer.

Building 41 - 14-unit residential rental, 3,800 sq ft, ISO class 1 (frame), Grand Prairie TX 75050. Construction year 1976. EagleView: roof age 22 years. Sprinklered N. Central station alarm Y. Protection class 5. Distance-to-hydrant 480 ft. One 2022 wind loss ($14K incurred, closed). Appetite analysis: roof age >15 years AND unsprinklered AND class 1 frame - multiple appetite negatives. Recommendation: decline OR quote-with-aggressive-restriction including $100K AOP, 5% Named-Storm, 70% co-insurance, full roof-age exclusion, water-backup excluded, ordinance-or-law sublimit reduced to $50K. Reason codes: (1) ISO construction class 1; (2) habitational occupancy; (3) roof age 22 years exceeding 15-year appetite threshold; (4) unsprinklered; (5) one prior wind loss within 5-year window. Protected-class proxy assessment: geographic underwriting in Grand Prairie reviewed against TDI Bulletin B-2024-3 and carrier's current bias-test exhibit dated 2026-Q1; no protected-class proxy identified in the variable set.

The Treaty-Cession Recommendation Section

The three locations above $25M each require facultative cession analysis. Treaty: $25M single-risk facultative threshold; surplus-treaty layer above; cat aggregate 78% consumed.

Carrollton location ($26.4M TIV). $1.4M above $25M retention. Facultative cession on $1.4M; quote-with-restriction implies cession economics work at standard reinsurance rates for class 5 commercial occupancy with clean losses. Recommendation: bind with $1.4M facultative cession; surplus-treaty involvement not required.

Mesquite location ($31.8M TIV). $6.8M above retention. Facultative cession on $6.8M; the location is a class 6 fire-resistive warehouse with sprinklered + alarmed + protection class 2 - best appetite profile in the account. Recommendation: bind with $6.8M facultative cession; reinsurance rates favorable given risk profile.

Grand Prairie location ($48.2M TIV). $23.2M above retention. Facultative + surplus-treaty layer. Building characteristics: class 6 fire-resistive, sprinklered, alarmed, protection class 1, clean losses. Recommendation: bind with $23.2M facultative + surplus-treaty cession; coordinate with reinsurance team on layered placement; treaty broker outreach required.

Cat-aggregate impact. Account's combined wind PML contribution: 0.8 points on 78% consumed = 78.8% post-bind. Within tolerance (carrier threshold 85%); flag for chief underwriting officer's portfolio-review attention.

The Missing-Information Requests and Producer Outreach

The triage memo enumerates missing-info per location with the source document that would carry it. Producer outreach script attached as deliverable.

15 locations without EagleView coverage. Roof age, roof material, roof slope, roof condition required. Source: producer's COPE worksheet or insured-supplied roof-inspection report. Deadline: 7 business days before bind. Underwriting impact: locations without roof data default to [refer for documentation] outcome.

Building 27 specifically. Roof inspection report required for the appetite-exception analysis; if roof >15 years, roof-age exclusion applies; if <=15 years, standard exception quote.

Building 41 specifically. Confirmation that the prior 2022 wind loss was closed with no open subrogation; loss-prevention investment record since the 2022 loss; if any sprinkler retrofit has occurred, documentation required.

Producer outreach script (excerpt). "Roper-Smith - thank you for the Acme Warehousing renewal submission. Per attached triage memo, we can bind 44 of 47 locations under our standard appetite. Three buildings (14, 27, 41) sit on appetite exception per habitational frame outside Tier 1 wind. Building 14 - quote-with-restriction draft attached. Building 27 - quote-with-restriction conditional on roof inspection (please provide within 7 business days). Building 41 - quote-with-restriction with documented adverse factors per attached reason codes; quote terms reflect roof age + unsprinklered + prior wind loss. Three locations above $25M need facultative cession; we will coordinate with our reinsurance team on Grand Prairie surplus-treaty placement. Please confirm acceptance of the attached terms or request modifications; bind target Friday."

The §4 Reason-Code Memo for the Account

The §4 reason-code memo is the §4.4 documentation artifact for the carrier's algorithm-inventory entry on the Acme submission. Every adverse recommendation in the triage memo carries its §4-compliant reason chain.

Building 41 decline recommendation (alternate to quote-with-aggressive-restriction). Variables driving decision: (1) ISO construction class 1 (frame); (2) habitational occupancy with 14 residential units; (3) roof age 22 years per EagleView retrieval, exceeding 15-year appetite threshold; (4) unsprinklered status per ACORD 140 and COPE narrative; (5) one prior wind loss within 5-year window ($14K incurred, closed 2022); (6) protection class 5; (7) distance-to-hydrant 480 ft. Protected-class proxy assessment: geographic underwriting in Grand Prairie reviewed against TDI Bulletin B-2024-3 and the carrier's current bias-test exhibit dated 2026-Q1; no protected-class proxy identified. AI signal: Cytora triage score 0.28 (refer-decline boundary); facts above justify either decline or aggressive-restriction quote depending on producer engagement. Verification: COPE worksheet confirms construction and protection class; EagleView retrieval confirms roof age; ISO ClaimSearch verifies the 2022 loss closure. NAIC §4 reason-chain documented; algorithm-inventory entry on Cytora deployment current.

The protected-class proxy assessment is non-negotiable. Every adverse recommendation involving geographic underwriting includes the protected-class review against the controlling state DOI bulletin. The Texas DOI Bulletin B-2024-3 framework is named; the carrier's bias-test exhibit date is cited; the variable set is reviewed for proxies; the assessment conclusion is documented. Missing the proxy review on geographic underwriting is the §4 audit failure that converts the artifact from defensible to exposed.

The Cytora-Style Triage Output and the Federato Handoff

The 12-section triage memo drops into Federato as a structured submission record. Each section maps to a Federato data field; downstream workflow consumes the structured output.

Section 1 (overall appetite) → Federato workbench appetite-status field with "refer-conditional-quote-with-restriction." Section 2 (per-building appetite map) → Federato per-location workflow with 47 records, each carrying the appetite status and any restriction. Section 3 (treaty-cession) → Federato reinsurance workflow with three cession records routed to the reinsurance team. Section 4 (cat-aggregate impact) → Federato portfolio-management dashboard with the 78.8% post-bind aggregate projection. Section 5 (habitational-frame analysis) → per-building exception-analysis records. Section 6 (missing-info requests) → broker-communication queue. Section 7 (reason codes) → §4.4 documentation chain. Section 8 (producer outreach script) → producer-communication queue. Section 9 (verification flags) → underwriter task queue for follow-up.

The Cytora workflow specifics. Cytora's submission triage layer ingests the prompt output, structures the workflow against the carrier's appetite guide, surfaces escalation triggers, and routes the file through the underwriting decision workflow. The integration with Federato (or the carrier's PAS workbench equivalent) is the L4 Garage-integration concern; the L2 student's task is producing the artifact in the structure both Cytora and Federato can consume.

The Verification Discipline Before the Artifact Leaves the Desk

The 60-second verification habit from L2 Lesson 3 operates on the triage memo before it lands in Federato. The underwriter scans: every form citation against ISO Mercury portal (10-15 seconds); every appetite-guide reference against the current carrier appetite guide v2026-04; every treaty constraint against the current treaty schedule; every loss-run citation against the 5-year loss-run source; every EagleView reference against EagleView retrieval; every protected-class proxy assessment against the bias-test exhibit; every Texas DOI Bulletin B-2024-3 citation against current TDI publication.

The file note logged at the end. "Acme Warehousing Inc. submission triaged 2026-05-28 by [underwriter]. Cytora triage memo produced via L2 prompt template v2026-Q2-04; model version Claude Sonnet 4.5 (carrier enterprise instance); RAG sources Acme submission packet + appetite guide v2026-04 + treaty schedule v2026-Q2 + EagleView coverage 32 of 47 + ISO ClaimSearch verified clean losses + TDI Bulletin B-2024-3 + bias-test exhibit 2026-Q1. Output reviewed against ISO/AAIS form citations, appetite guide, treaty constraints, loss-run, and protected-class proxy framework. §4 reason chains documented per adverse recommendation. Artifact routed to Federato as submission record. Producer outreach scheduled for 9:30 a.m. via [agency channel]."

Key Takeaways

• The Acme Warehousing submission is the canonical L2 UW triage case. 47 buildings, $182M TIV, three above $25M ($26.4M Carrollton, $31.8M Mesquite, $48.2M Grand Prairie), three habitational-frame appetite exceptions (buildings 14, 27, 41), treaty $25M facultative threshold, cat aggregate 78% consumed.
• The triage prompt applies the L2 Lesson 1 + Lesson 2 architecture. System message names underwriter role + §4 discipline + hallucination restrictions. User message loads the full submission context. Artifact is the 12-section Cytora triage memo. Constraints prevent the five failure modes plus geographic-proxy fabrication.
• The habitational-frame exception analysis on Buildings 14, 27, 41 is the highest-leverage analytical surface. Each building has its own reason chain - Building 14 fits appetite exception (sprinklered + alarmed + clean + 12-year roof); Building 27 requires roof inspection; Building 41 has multiple negatives (22-year roof + unsprinklered + prior wind loss).
• Treaty-cession recommendations cover the three locations above $25M. Carrollton ($1.4M facultative); Mesquite ($6.8M facultative); Grand Prairie ($23.2M facultative + surplus-treaty layer with reinsurance team coordination).
• Cat-aggregate impact projects 78.8% post-bind from 78% consumed. Within tolerance (85% threshold); flagged for chief underwriting officer portfolio review.
• Missing-info requests cover the 15 locations without EagleView plus Buildings 27 and 41 specifically. Producer outreach script names each request with deadline and underwriting impact.
• The §4 reason-code memo carries the protected-class proxy assessment for every adverse recommendation. Texas DOI Bulletin B-2024-3 framework named; current bias-test exhibit date cited; variable set reviewed for proxies; assessment conclusion documented.
• The 60-second verification habit operates before the artifact leaves the desk. Every form citation, appetite reference, treaty constraint, loss-run, EagleView reference, and proxy assessment scanned against authority. File note logged with prompt template version, model version, RAG sources, and §4 reason chain summary.
• The 12-section triage memo drops into Federato as structured submission record. Per-section field mapping into appetite, per-location, reinsurance, portfolio, exception-analysis, broker queue, §4.4 documentation, producer queue, underwriter task queue.
