+# Account Dossier Interactive Dashboard — Design Document
+
+**Version:** 0.1 (MVP)  
+**Author:** Claude  
+**Date:** 2026-10-07  
+**Status:** Design Review (Pre-Prototype)
+
+---
+
+## 1. Overview & Purpose
+
+**What:** Interactive HTML/React dashboard that surfaces account intelligence for a single Pure Storage customer or prospect. Provides a "10,000 ft view" with drill-down to ground-level detail.
+
+**Why:** SEs need to move quickly from account snapshot → discovery prep → conversation context without context-switching between Sheets, notes, and browser tabs. One dashboard per customer becomes the source of reference for that account.
+
+**MVP Scope:** The 10 essential questions (List 1 + List 2 from account intelligence framework)
+
+**Future Scope:** Relationships, opportunities, financial modeling, industry trends, sentiment analysis, timeline views
+
+---
+
+## 2. User Personas & Use Cases
+
+### Primary User
+**Ryan** (You, Enterprise SE)
+- Prepping for discovery calls
+- Hunting for competitive displacement opportunities
+- Planning expansion/renewal strategy
+- Sharing account context with team (future)
+
+### Use Cases (in priority order, all equally weighted for MVP)
+
+| Use Case | What They Need | Where Dashboard Helps |
+|----------|---|---|
+| **Pre-call Prep (15 min before discovery)** | Quick account snapshot + key metrics + conversation hooks | Overview pane + drill-down to specific List items; see what changed since last call |
+| **Competitive Displacement Hunting** | Incumbent vendors + footprint + gaps + consolidation leverage | List 2 drill-down showing Pure coverage % + high-value data not on Pure; see EMC systems aging |
+| **Expansion/Renewal Planning** | Growth trajectory + budget cycle + stakeholder sentiment + upcoming initiatives | Opportunity tab (future) + timeline + stakeholder relationships; see refresh window + budget headroom |
+
+### Secondary User (Future)
+**Account team** (Sales, Solution Architect, Customer Success)
+- Read-only view of account summary
+- Understand strategic context before customer calls

+### 4.2 Left Pane: Account Overview (10,000 ft)
+
+**Purpose:** At a glance, is this account healthy? What's the most critical thing to know?
+
+**Components:**
+
+#### Health Scorecard (4 KPIs)
+Visual status cards, each with:
+- **Metric name** + current value
+- **Trend indicator** (↑ up, ↓ down, → flat)
+- **Status badge** (green / yellow / red)
+- **Drillable** — click to zoom into that metric
+
+**KPIs (MVP):**
+1. **Pure Coverage** — % of total storage on Pure
+   - Value: 30% | Trend: ↑ +5% YoY | Status: 🟡 Opportunity
+   - Rationale: Shows expansion potential; top sales driver
+
+2. **Fleet Age** — Average age of Pure systems
+   - Value: 4.2 yr | Trend: → flat | Status: 🟡 Refresh Window Approaching
+   - Rationale: Indicates refresh opportunity timing
+
+3. **Expansion Opportunity Size** — $ value of consolidation potential
+   - Value: $3.5M | Trend: ↑ Growing | Status: 🟢 Pipeline-Ready
+   - Rationale: Deal size at a glance; guides priority
+
+4. **Engagement Momentum** — Recency of last interaction + champion sentiment
+   - Value: 5 days | Trend: ↑ Active | Status: 🟢 Engaged
+   - Rationale: Is this account warm or cold?
+
+#### Key Dates Timeline
+Visual timeline of critical dates:
+- **Refresh Date**: Next Pure system refresh
+- **Budget Cycle**: When capex decisions happen
+- **Contract Renewal**: When Pure contract is up
+- **Next Review**: When you should reconnect
+
+Format: Horizontal timeline or vertical list with "X days until" callouts.
+
+#### Action Buttons (Quick nav)
+- **QBR Prep** → Opens checklist template
+- **Edit Account** → Opens Sheets in new tab
+- **View Notes** → Opens Obsidian vault or embedded Markdown
+- **Share** → (Future) generates shareable summary link
+- **Log Interaction** → Quick-add form (bottom right pane)
+
+---
+
+### 4.3 Center Pane: Details & Drill-Down
+
+**Purpose:** Zoom from 10K ft into List 1 and List 2 metrics. See details, trends, and rationale.
+
+**Tab Structure:**
+
+#### Tab 1: Overview (Summary of all 10 items)
+Shows all 5 List 1 items + all 5 List 2 items as **cards in a grid**:
+- Card layout: Title | 10K ft summary | Status badge | Click to drill
+- Color-coded by item type (List 1 = blue accent, List 2 = green accent)
+- Scanning-friendly; can see account at a glance
+
+#### Tab 2: Account Profile (List 1 Deep Dive)
+Five expandable cards, one per List 1 item:

+#### Status Badges & Visual Indicators
+| Status | Color | Meaning |
+|--------|-------|---------|
+| 🟢 Green | Good / On Track / Advocate | Positive signal |
+| 🟡 Yellow | Caution / Aging / Neutral | Attention needed |
+| 🔴 Red | Risk / Critical / Urgent | Action required |
+| ⚪ Gray | Unknown / TBD | Need more info |
+
+#### Data-Driven Highlights
+Conditional visual emphasis on metrics:
+- **Refresh window approaching** (>4yr age) → Highlighted in yellow
+- **Coverage gap opportunity** (low % Pure) → Highlighted in orange
+- **Budget cycle in next 90 days** → Underlined with "upcoming" tag
+- **Strong champion sentiment** → Starbursts/badge next to name

+## 6. Visual Design Principles
+
+### Color Palette (Themeable)
+- **Accent Blue** (Primary): List 1 items, account overview
+- **Accent Green** (Secondary): List 2 items, Pure deployment
+- **Status Green** (Success): Healthy, positive, on-track
+- **Status Yellow** (Warning): Approaching refresh, caution needed
+- **Status Red** (Critical): Urgent action required
+- **Neutral Gray**: Unknown, TBD, secondary content
+- **Text Dark Gray** (Light mode) / **Text Light Gray** (Dark mode)
+- **Background**: Light/dark mode adaptive
+
+### Typography
+- **Header**: Large, bold, account name stands out
+- **Tab titles**: Medium weight, clear tab distinction
+- **Card titles**: Semi-bold, clickable indicator (▼)
+- **Data values**: Monospace for numbers (easier to scan)
+- **Labels**: Smaller, muted color
+
+### Spacing & Layout

+- **Cards**: Padding ~20px, margin ~16px between cards
+- **Drill-down**: Animated 200ms expand/collapse
+- **Mobile**: Stack panes vertically (future consideration)
+
+---
+
+## 7. Navigation & User Flows
+
+### Flow 1: Pre-Call Prep (15 min before discovery)
+```
+User lands on dashboard
+    ↓
+Glances at Health Scorecard (30 sec) — "Pure coverage 30%, fleet aging, $3.5M upside"
+    ↓
+Checks Key Dates Timeline (30 sec) — "Budget cycle in 3 mo, refresh in 18 mo"
+    ↓
+Clicks "QBR Prep" action → Opens checklist template in new tab
+    ↓
+Scrolls to Center pane, clicks "Current Vendors" card to see EMC footprint
+    ↓
+Reads right pane: "Customer risk-averse on primary storage; use reference story"
+    ↓
+Click [Log Interaction] → Pre-fills with today's call, ready to document post-call
+```
+
+### Flow 2: Competitive Displacement Hunt
+```
+User is looking for displacement opportunities
+    ↓
+Opens Account dashboard
+    ↓
+Glances at Scorecard: "Pure coverage 30%" → Opportunity
+    ↓
+Clicks "Data Footprint" card → Sees workload breakdown
+    ↓
+Clicks "Current Vendors" card → Sees EMC system (200TB, 6yr old, primary OLTP)
+    ↓

+    ↓
+Action: Schedule architecture review with Sarah for Q1; prepare proposal for analytics move
+```
+
+---
+
+## 8. Data Sync & Freshness
+
+### MVP Approach: Manual Sync
+- **Sheet → Dashboard**: Copy-paste JSON export or Google Sheets API call (daily/on-demand)
+- **Markdown → Dashboard**: Fetch from Obsidian API or GitHub if synced
+- **Freshness**: Dashboard is "point-in-time snapshot" at time of load
+- **Update frequency**: User refreshes page or manually syncs from edit screens
+
+### Future: Live Sync
+- Dashboard queries Google Sheets API in real-time
+- Interactions logged directly to Sheets (no manual re-entry)
+- Markdown fetched from Obsidian Sync API
+- Auto-refresh KPIs every 5 minutes
+
+---
+
+## 9. Extensibility Points (Future Phases)
+
+### Phase 2: Relationships & Interaction History
+- **Tab 4: Relationships** — Org chart, sentiment timeline, interaction history
+- **Interaction log** — Searchable, filterable by contact, type, sentiment
+- **Sentiment analysis** — Chart showing mood trend over time
+
+### Phase 3: Opportunities & Pipeline
+- **Tab 5: Opportunities** — Consolidation roadmap, deal timeline, revenue forecast
+- **Milestone tracking** — Countdown to RFP, contract close, etc.
+
+### Phase 4: Financial Modeling
+- **10-K integration** — Embed PDF link, key metrics extracted
+- **Opportunity forecasting** — If analytics consolidates, revenue impact
+- **Budget impact model** — Capex vs. OpEx trade-off calculator
+
+### Phase 5: Industry & Competitive Context
+- **Industry trends** — Curated insights relevant to account
+- **Competitor tracking** — Win/loss intelligence, displacement playbooks
+- **Market context** — Industry growth rates, regulatory changes
+
+---
+
+## 10. Technical Architecture
+
+### Technology Stack
+- **Frontend**: React (or vanilla JS if keeping simple)
+- **Styling**: Tailwind CSS (or custom CSS-in-JS)
+- **Data sources**: 
+  - Google Sheets API (for Account, Pure-Deployment, Relationships, Financials tabs)
+  - Markdown file (from Obsidian or GitHub)
+- **Deployment**: Claude artifact (publishable, shareable URL) or self-hosted on homelab
+- **Build**: Vite (fast dev) or Create React App
+
+### API Integration (MVP)
+```
+Frontend (React)
+    ↓
+    ├─→ Google Sheets API v4
+    │   └─ Fetch: Account!A:Z, PureDeployment!A:Z, Relationships!A:Z, etc.
+    │      Rate: On-demand or 5-min cache
+    │
+    └─→ Markdown fetch (via Obsidian API or raw GitHub/Drive link)
+        └─ Fetch: Markdown content, parse for snippets
+```
+
+### State Management
+- **Client-side state**: React hooks (useState, useEffect)
+- **Server state**: Google Sheets is source of truth
+- **UI state**: Which tab active, which card expanded
+- **No local storage** (MVP): Always fresh from source
+
+---
+
+## 11. Accessibility & Usability
+
+### Keyboard Navigation
+- Tab through cards, tabs, buttons
+- Enter/Space to expand cards
+- Escape to collapse all
+- Ctrl/Cmd+Click to open links in new tab
+
+### Screen Readers
+- Semantic HTML (headers, nav, main, article)
+- ARIA labels on custom components
+- Heading hierarchy (H1 = account name, H2 = tabs, H3 = card titles)
+
+### Color Contrast
+- All text meets WCAG AA standards
+- Status indicators have labels (not color alone)
+- Links underlined or clearly differentiated
+
+### Mobile Responsiveness (Future)
+- Stack panes vertically on small screens
+- Touch-friendly button sizes (44px minimum)
+- Collapsible sections for readability
+
+---
+
+## 12. Success Metrics (MVP)
+
+| Metric | Target | How to Measure |
+|--------|--------|---|
+| **Time to account snapshot** | <2 min to full context | User time log |
+| **Drill-down effectiveness** | Find key metric in <30 sec | User task test |
+| **Information completeness** | All 10 items readily visible | Checklist |
+| **Visual clarity** | No confusion on next steps | User feedback |
+| **Engagement** | Used for all 3 use cases equally | Usage logs |
+
+---
+
+## 13. Known Constraints & Trade-offs
+
+| Constraint | Impact | Mitigation |
+|-----------|--------|---|
+| **Manual sync (MVP)** | Data can lag if Sheets updated but dashboard not refreshed | Clear "last updated" timestamp; button to manual sync |
+| **No real-time collaboration** | If account team edits Sheets while viewing dashboard, changes won't appear until reload | Future: implement live sync |
+| **Single-customer dashboard** | Can't compare metrics across accounts in MVP | Future: roll-up view with filtering |
+| **API rate limits (Sheets)** | Can't refresh dashboard every second | Cache on client; user triggers refresh manually |
+
+---
+

+
+## LIST 1: ANY CUSTOMER OR PROSPECT
+### First Discovery Call + Competitive Displacement + Expansion Foundation
+
+---
+
+### 1. **Data Footprint and Workload Breakdown**
+
+**What to capture:**
+- Total addressable storage capacity (current + 2-year projection)
+- Workload tier split: critical OLTP (databases, transactional), warm operational analytics (data warehouses, ML training sets), unstructured (data lakes, backups, archives)
+- Annual growth rate
+- Typical IO patterns (sequential vs. random, read/write mix)
+- Workload sources: core business apps, digital channels, analytics platforms, third-party integrations
+
+**Why it ranks #1:**
+This is your credibility foundation for the discovery call. Large enterprises in financial services and retail/manufacturing operate at scale—you need to know if they're managing 10PB or 500PB of storage before you can ask intelligent questions about consolidation, resilience, or performance. For competitive displacement, it tells you the total addressable market and which workloads are most valuable to move. For expansion, it shows you where growth is (analytics workloads often outpace transactional growth in these verticals).
+
+**Vertical differences:**
+- **Financial services:** Regulatory data tiers (Basel III, Dodd-Frank, GDPR-driven data governance), transaction volumes, archive-to-compliance mandates, and fraud detection datasets are outsized here.
+- **Retail/manufacturing:** Omnichannel transaction data, supply chain event data, and IoT/sensor streams create different growth patterns—often unstructured-heavy.
+
+**Where to get it:**
+Account team, analyst kickoff, customer IT strategy documents. If public: earnings calls (capex guidance), analyst reports on data center expansion. **Hard to verify fully from public sources—lean on the account team and discovery conversation.** Pure1 for existing customers (capacity trends, growth rates).
+
+---
+
+### 2. **Current Storage Vendor(s) and Installed Infrastructure**
+
+**What to capture:**
+- Primary vendor(s), total installed capacity per vendor, system age/generation
+- Deployment model (on-prem, cloud-hosted)
+- Vendor concentration (single-vendor, multi-vendor)
+- Capacity consolidation potential (old systems due refresh, overlapping vendors)
+- Competitive systems they've ruled out or are evaluating
+
+**Why it ranks #2:**
+This is the competitive map. In discovery, you need to know who you're up against to ask credible questions about their stack. For displacement, this is your roadmap—old NetApp or EMC systems are your opening; vendor sprawl is your consolidation story. For expansion, it shows where Pure is (or isn't) and where you can grow.
+
+**Applies to both verticals:**
+Regulatory and operational requirements often enforce heterogeneous stacks (legacy core systems, newer analytics platforms), creating multi-vendor complexity and Pure's consolidation angle.
+
+**Where to get it:**
+Account team, customer IT contacts, Gartner/IDC reports, job postings (hiring for specific platforms signals infrastructure). Pure's competitive intel teams (if available in your region). **Harder to get from public sources—interview in discovery.**
+
+---
+
+### 3. **Business Drivers and Strategic Imperatives**
+
+**What to capture:**
+- What's moving their infrastructure strategy in the next 12–24 months?
+- Digital transformation (cloud-first, API-led architecture)
+- M&A (data center consolidation, platform rationalization)
+- Regulatory change (data residency, compliance modernization)
+- Cost reduction (capex or opex pressure)
+- Performance demands (real-time analytics, AI/ML acceleration)
+- Geographic expansion (multi-site, disaster recovery)
+
+**Why it ranks #3:**
+This explains *why* they'll spend and *when*. For discovery, it tells you what your conversation should be anchored to—cost pressure is a different conversation than compliance urgency. For displacement, it reveals openings (legacy vendor can't support cloud migration; incumbent doesn't scale for analytics). For expansion, it shows where budget flows and growth cycles.
+
+**Vertical differences:**
+- **Financial services:** Regulatory change (Fed data residency mandates, CCAR/stress test infrastructure), fraud detection (AI/ML workloads), and open banking/fintech competition drive transformation.
+- **Retail/manufacturing:** Omnichannel unification, supply chain visibility, and sustainability reporting (ESG data) are primary drivers; cost pressure is often secondary.
+
+**Where to get it:**
+Earnings calls (CFO and CRO commentary), industry analyst reports, customer executives in discovery (CEOs and CFOs speak to this), account team (relationship intelligence). Regulatory announcements for financial services. **Public sources vary—direct ask is usually most productive.**
+
+---
+
+### 4. **Infrastructure Architecture and Resilience Model**
+
+**What to capture:**
+- Topology: single data center, active-active multi-site, hub-and-spoke?
+- Failover strategy (RPO/RTO targets, synchronous vs. asynchronous replication)
+- Cloud presence (public cloud, hybrid, private cloud)
+- Containerization and Kubernetes adoption
+- Storage tiers and tiering automation
+- Backup/archive strategy (separate systems, integrated)
+
+**Why it ranks #4:**
+This determines *which* Pure solutions fit and how. Knowing they're multi-site tells you Evergreen model and replication are critical; knowing they have Kubernetes tells you Portworx is on the menu; knowing they're chasing sub-second RTO tells you FlashArray's performance story matters. For discovery, it frames the conversation around resilience or performance. For displacement, it shows where Pure's architecture outperforms incumbent (e.g., Evergreen's native replication vs. bolted-on replication). For expansion, it guides where to add capacity.
+
+**Vertical differences:**
+- **Financial services:** Recovery requirements are often strict (RTO <1hr, RPO <15min); multi-site is standard; compliance mandates geographic separation.
+- **Retail/manufacturing:** Multi-site is common (stores, plants, distribution); RTO is important but often longer than financial services; hybrid cloud adoption is accelerating.
+
+**Where to get it:**
+Account team, technical RFI/RFQ documents, infrastructure diagrams (security-sensitive—may not be public). Discovery conversation with IT infrastructure/storage teams. **Hard from public sources.**
+
+---
+
+### 5. **Budget Cycle, Capital Allocation, and Buying Authority**
+
+**What to capture:**
+- Capex budget cycle and approval gates (who approves? quarterly, annual, rolling?)
+- Capex vs. opex preference (traditional capex, Evergreen-style subscription, OpEx-only mandate)
+- Budget envelope for infrastructure over next 2 years
+- Preferred buying patterns (competitive bid, existing vendor preference, tech refresh cycle)
+- Influencers and decision-makers (CIO, VP Storage, business unit leaders, CFO)
+
+**Why it ranks #5:**
+This is the "when and how to sell" lever. It's less about discovery credibility (though knowing budget is essential) and more about deal realism. For discovery, it tells you timing and buying authority to route follow-ups. For displacement, it tells you if capex is available or if you need to frame Evergreen as an alternative. For expansion, it reveals budget headroom and buying rhythm.
+
+**Applies to both verticals:**
+Financial services often have tighter capex scrutiny and longer approval cycles; retail/manufacturing may have faster refresh cycles but more budget constraints post-acquisition integration.
+
+**Where to get it:**
+Account team relationship notes, past deal history, 10-K/10-Q filings (capex guidance), analyst reports, budget forecasts shared in customer relationships. **Rarely fully public—account team and direct relationship intelligence are key.**
+
+---
+
+## LIST 2: EXISTING CUSTOMERS — PURE STORAGE DEPLOYMENT SPECIFICS
+### Expansion + Retention + Competitive Defense
+
+---
+
+### 1. **Current Pure Installed Base, Deployment Pattern, and Capacity**
+
+**What to capture:**
+- FlashArray systems (models, capacity per system, tier across data centers or cloud regions)
+- FlashBlade deployments (scale-out analytics use cases, capacity)
+- Portworx deployments (if any; containerized workloads, environments)
+- Age of systems (when deployed; refresh cycle status)
+- Geographic footprint (on-prem across which data centers, any cloud-hosted Pure?)
+- Utilization and headroom (at capacity, growing into headroom, or sparse?)
+
+**Why it ranks #1:**
+You can't expand without knowing your baseline. For expansion, this is your starting point—you need to know what they own to identify the next sale (add capacity, new tier, new workload). For retention, it's your health baseline (old systems more likely to churn). For competitive defense, it shows Pure's footprint and where competitors might try to take share.
+
+**Key indicators for retention/expansion:**
+Systems older than 5 years are refresh candidates; sparse utilization may indicate underutilized tier or expansion opportunity; multi-site Pure deployments are higher-value accounts.
+
+**Where to get it:**
+**Pure1 (your best data source—capacity, performance, age, location),** internal Pure account data, customer IT/storage teams. Direct ask in customer reviews and strategic business reviews (QBR/SBR).
+
+---
+
+### 2. **Performance, Utilization, and Customer Satisfaction**
+
+**What to capture:**
+- Pure1 performance metrics (latency, IOPS achieved vs. provisioned, dedupe/compression ratios, capacity growth rate)
+- Storage team feedback (support experience, feature requests, known pain points)
+- Performance satisfaction (are performance SLAs being met?)
+- Operational efficiency gains (cost per GB, power/cooling reduction)
+- Customer sentiment (NPS or equivalent; any churn signals?)
+
+**Why it ranks #2:**
+This tells you expansion potential vs. churn risk. If they're unsatisfied, expansion is at risk (competitor threat, bargaining power). If they're thriving on Pure, expansion is easier (proven business case). For retention, this is your early warning system. For expansion, high satisfaction is your foundation for upsells (new workload, new tier, cloud-native).
+
+**Vertical differences:**
+- **Financial services:** Customers often have strict uptime/performance mandates.
+- **Retail/manufacturing:** Often cost-conscious and may trade performance for efficiency.
+
+**Where to get it:**
+**Pure1 (performance analytics),** NPS/CSAT surveys, QBR discussions, support ticket sentiment, sales/SE relationship notes. Direct ask: "How is Pure performing for you?"
+
+---
+
+### 3. **Data Footprint Not Yet on Pure / Coverage Gap Analysis**
+
+**What to capture:**
+- Percentage of their total storage on Pure vs. other vendors
+- Workload segments not on Pure (e.g., older OLTP databases on EMC, analytics on Hadoop/object storage, backups on separate vendor)
+- Highest-value data not on Pure (revenue-generating apps, critical analytics)
+- Consolidation opportunities (multi-vendor overlap, legacy systems ready to refresh)
+- Workloads Pure could address but hasn't yet (emerging use cases, cloud data, new business initiatives)
+
+**Why it ranks #3:**
+This is your expansion TAM within the account. For expansion, it shows where growth comes from (consolidation opportunity, new workload, tier migration). For competitive defense, it identifies where competitors will attack (the gap is their opening). For retention, it's leverage—you want to own more of their data.
+
+**Vertical differences:**
+- **Financial services:** Critical OLTP often stays on incumbent (lower risk perception); newer analytics and fraud detection data are Pure opportunities.
+- **Retail/manufacturing:** Supply chain/IoT data and unstructured analytics are often on non-Pure platforms; consolidation gains are high here.
+
+**Where to get it:**
+**Pure1 (shows only Pure capacity—you need to ask for total footprint),** customer IT (data inventory), discovery/expansion conversations. **Often not transparent from public sources—direct conversation essential.**
+
+---
+
+### 4. **Upcoming Infrastructure Initiatives and Technology Refresh Cycles**
+
+**What to capture:**
+- Planned data center consolidation or modernization
+- System refresh dates (when is their oldest Pure system past end-of-support? When's the next capex cycle?)
+- Cloud migration plans (moving workloads to cloud; implications for on-prem storage)
+- New workloads (AI/ML platforms, real-time analytics, new business lines)
+- Multi-site expansion or disaster recovery modernization
+
+**Why it ranks #4:**
+Timing is everything in expansion. Refresh cycles are your biggest lever (old systems = new capex = new opportunity). Cloud migration can cut Pure TAM or open Portworx opportunities. New workloads are expansion hooks. For expansion, this is your calendar. For retention, knowing refresh timing lets you plan defense early.
+
+**Applies to both verticals:**
+Financial services often have annual capex cycles tied to business planning; retail/manufacturing may refresh faster or slower depending on store/plant footprint changes.
+
+**Where to get it:**
+Customer IT roadmap (often multi-year), Pure account team, QBR discussions, earnings announcements (for large public customers, CapEx guidance), customer executives. Sometimes in customer's published IT strategy.
+
+---
+
+### 5. **Stakeholder Relationships, Expansion Readiness, and Competitive Threats**
+
+**What to capture:**
+- Key stakeholders (CIO, VP Storage, business unit leaders, security/compliance officers)
+- Champion(s) (who advocates for Pure?)
+- Relationship temperature (trust, satisfaction, barriers)
+- Competitive interest (have they mentioned other vendors? RFPs? Evaluation?)
+- Budget headroom (will they invest more in storage in next 12–24 months?)
+- Expansion appetite (are they open to moving more workloads to Pure, or focused on optimization?)
+
+**Why it ranks #5:**
+This is your "how to expand" lever. Knowing who the champion is tells you how to navigate. Knowing if they're under competitive attack tells you how urgent your defense is. Knowing budget appetite tells you if expansion is realistic. For expansion, this is your relationship risk/opportunity assessment. For retention, it's your early warning for churn or your pathway for growth.
+
+**Applies to both verticals:**
+In large enterprises, storage decisions often flow through business unit leaders (not just IT); understanding where Pure fits in their strategic priorities is key.
+
+**Where to get it:**
+Account team relationship notes, past deal history, QBR feedback, sales/SE interactions, industry/analyst events. Direct ask in customer conversations: "Where do you see us helping you grow?"
+
+---
+
+## Summary: Why This Order Matters
+
+**List 1** (any customer/prospect) moves from **foundational understanding** (what and who) → **context** (why and how) → **execution** (when and who decides). This sequence builds credibility in discovery while revealing competitive and expansion levers.
+
+**List 2** (existing customer Pure deployments) moves from **your current position** (what you have) → **relationship health** (how it's performing) → **opportunity size** (what you could have) → **timing** (when they'll buy) → **execution** (how to navigate the sale). This sequence is your expansion playbook.
+
+### Key Callout
+In both lists, **items 1–3 should drive 80% of your discovery and account strategy effort**. Items 4–5 refine timing and approach. **Start here, then layer in the operational details** (support SLAs, feature adoption, roadmap alignment) as you deepen the relationship.
+
+---
+
+## Quick Reference: Source Hierarchy by Item
+
+| Item | Primary Source | Secondary Source | Public Availability |
+|------|---|---|---|
+| **List 1 #1** – Data Footprint | Account team, customer IT | Earnings calls, analyst reports | Moderate (public guidance varies) |
+| **List 1 #2** – Current Vendors | Account team, IT contacts | Job postings, Gartner reports | Low (often internal knowledge) |
+| **List 1 #3** – Business Drivers | Customer executives, analyst reports | Earnings calls, regulatory filings | Moderate (CEOs/CFOs speak to this) |
+| **List 1 #4** – Architecture | Technical RFI/RFQ, account team | Discovery conversation | Low (security-sensitive) |
+| **List 1 #5** – Budget/Authority | Account team, past deal history | 10-K/10-Q, customer relationships | Low (relationship intelligence) |
+| **List 2 #1** – Pure Installed Base | **Pure1** (best source), account data | Customer IT, QBR | Account-internal only |
+| **List 2 #2** – Performance/Satisfaction | **Pure1**, NPS surveys | Support tickets, QBR discussions | Account-internal only |
+| **List 2 #3** – Coverage Gaps | Customer IT inventory, discovery | Account team insights | Low (direct conversation required) |
+| **List 2 #4** – Refresh Cycles | Customer IT roadmap, account team | QBR, earnings announcements | Low-Moderate (customer-dependent) |
+| **List 2 #5** – Stakeholder/Competitive | Account team, sales history | QBR feedback, customer conversations | Account-internal only |
+
+---
+
+**Use this as your go-to reference before discovery calls, account strategy reviews, and expansion planning.**

+# Data-driven list consumed by roles/llm-inference-multimodel tasks/models.yml
+# (loop -> tasks/stage_model.yml). Each entry is idempotently staged into
+# /opt/models: stat + EXACT-size check vs HF manifest; skip (no download, no
+# restart) when present + size matches. Source repos are public bartowski GGUFs
+# on HuggingFace (no auth). A router restart is notified ONLY when a new GGUF
+# is actually downloaded.
+# Added 2026-08-12 (War Machine): codify Phi-3.5-mini-instruct-Q8_0 and
+# Meta-Llama-3.1-8B-Instruct-Q4_K_M as router models alongside the production
+# Qwen3.6-35B-A3B-UD-Q4_K_S. The live files were already present/correct on
+# astro-orbiter; this pass codifies them. Future adds = append to this list.
+# Router --models-max override for astro-orbiter.
+# Default in defaults/main.yml is 1 (conservative). Bumped to 4 on 2026-08-12
+# (t_33acbb2e) so the router can keep more than one GGUF resident on-demand
+# and LRU-evict when needed.
+#
+# VRAM NOTE (t_33acbb2e, updated t_55c164f5, updated t_34b96e83, updated t_f5f7e9ad, updated t_441470b9, updated t_c5cef2b2):
+# With models-max=4 and all 6 GGUFs registered, worst case is all 6 loaded simultaneously:
+#   Qwen3.8-27B Q4_K_M:               ~20.0GB (weights ~17.1GB + KV ~2.9GB @ 65536 ctx, q4_0) ← CORRECTED (ctx rolled back from 128K to 65536, t_c9fed26c 2026-08-18)
+#   Phi-3.5-mini-instruct Q8_0:       ~4.3GB  (weights ~3.8GB + KV ~0.5GB @ 32K ctx)
+#   Meta-Llama-3.1-8B Q4_K_M:        ~5.6GB  (weights ~4.6GB + KV ~0.2GB @ 8K ctx)
+#   Qwen2.5-Coder-14B Q4_K_M:        ~9.0GB  (weights ~8.4GB + KV ~0.6GB @ 16K ctx)
+#   nomic-embed-text-v1.5 Q4_K_M:    ~0.09GB (~84MB, embedding only — no KV cache)
+#   Qwen3-8B Q4_K_M:                 ~5.5GB  (weights ~4.68GB + KV ~0.5GB @ 32K ctx, q4_0)
+#   Total worst-case:                 ~44.5GB  >>  24GB RTX 3090
+#
+# OOM RISK: Full co-residency is impossible on 24GB. LRU eviction prevents this
+# in practice: models-max=4 means the router can REGISTER 6 models but only keeps
+# up to 4 LOADED simultaneously — the router will evict the LRU model when a new
+# one is needed. nomic-embed-text-v1.5 is pinned via sleep-idle-seconds=-1 and
+# load-on-startup=true but it uses only ~84MB, so it never meaningfully changes
+# the budget. In single-user homelab operation, only one generative model is active
+# at a time alongside the always-resident embedding model.
+# Qwen3.8-27B alone uses ~17,804 MiB (weights+KV @ 65536 ctx); co-residency
+# with Coder (~9GB) = ~27GB > 24GB. LRU eviction handles this automatically.
+# Ryan should be aware this means model-switching always incurs a ~30-60s
+# cold-load latency when switching between Qwen3.8-27B and any other model.
+# Proceeding to models-max=4 as instructed; flagged for Ryan's attention.
+# Router --models-max override for astro-orbiter.
+# UPDATED (t_f5f7e9ad, 2026-08-16): Set to 2 because Qwen3.8-27B-Q4_K_M
+# uses 17,804 MiB at 65536 ctx. Only nomic-embed (558MB, pinned) and ONE
+# generative model can be resident simultaneously. Co-residency of Qwen3.8
+# with any auxiliary model (Phi 8.3GB, Llama 5.9GB, Coder 9GB) exceeds 24GB.
+# models-max=2: slot 1 = nomic-embed (pinned, always loaded), slot 2 = LRU
+# generative model (Qwen3.8 primary, cold-loaded on first request ~30-60s;
+# auxiliary models evict it on demand, and vice versa).
+# NOTE: Qwen3.8 does NOT have load-on-startup — it loads on first request.
+# This avoids an LRU eviction race with nomic-embed at startup.
+# UPDATED (t_72646029, 2026-08-17): CPU offload for Coder + Llama changes the
+# constraint. Coder and Llama now use CPU inference (n-gpu-layers=0). GPU-resident
+# VRAM: Qwen3.8 (~17,804 MiB at 65536 ctx) + nomic-embed (558 MiB, pinned) plus
+# the CUDA-context buffers llama.cpp 6ea215d allocates for the CPU models (~1.4-1.7GB
+# each) = ~20,004 MiB steady-state, below the 24,576 MiB physical limit.
+# CORRECTED (t_c5cef2b2, 2026-08-19): ctx-size was rolled back from 131072 to 65536
+# (t_c9fed26c 2026-08-18). Qwen3.8 VRAM at 65536: 17,804 MiB (not 20,302 MiB).
+# models-max raised to 4: nomic (slot 1, pinned) + Qwen3.8 (slot 2, GPU) +
+# Llama (slot 3, CPU) + Coder (slot 4, CPU). Phi (GPU, ~8.3GB) and new
+# Qwen3-8B (GPU, ~5.5GB) can also be requested but evict Qwen3.8 due to VRAM.
+# models-max=4 is required so CPU-offloaded models count as loaded without

+# "Single model only" — nomic-embed-text-v1.5 (embedding, :8020) and

+# endpoint, already stopped) — confirmed with Ryan before disabling.
+#
+# Model choice: casperhansen/deepseek-r1-distill-qwen-32b-awq — same
+# quantizer/toolchain (AutoAWQ) as the outgoing Qwen2.5-32B-Instruct-AWQ,
+# widely used, 4-bit GEMM AWQ, ~19.3GB on disk (4 safetensors shards).
+# Architecture: Qwen2ForCausalLM (DeepSeek-R1 distilled onto Qwen2.5-32B
+# base) — same vLLM code path as the outgoing model, no new serving
+# support needed. Native max_position_embeddings=131072; we cap at 32768
+# per the task's explicit max-model-len requirement.
+#
+# VRAM math: ~19.3GB weights (4-bit AWQ) + KV cache at 32768 ctx (GQA,
+# 8 KV heads, 128 head_dim, 64 layers, fp16 KV by default) ≈ 19.3GB +
+# ~4GB KV+overhead ≈ 23.3GB — tight but the FULL 24GB card is now
+# available (no co-resident nomic-embed/Qwen3-8B taking a share, unlike
+# the outgoing Qwen2.5-32B config). gpu_memory_utilization=0.95 (role
+# default) + enforce_eager retained as the proven-stable mitigation from
+# t_e6facb19/t_ca1af9fb (avoids CUDA graph capture VRAM spike; this host's
+# only validated way to avoid crash-loop-to-stabilize behavior on this
+# card). If 0.95 OOMs at 32768 ctx once tested live, drop to 0.90 next
+# (documented fallback, same pattern as the outgoing model).
+#
+# DeepSeek-R1 output note: reasoning traces stream in <think> tags before
+# the final answer — this is expected R1-distill behavior, not a bug.
+# Model card recommends temperature 0.5-0.7 (not 0, not vLLM's greedy
+# default) to avoid repetition/incoherence; not set here (server-side

+# Router --models-max override for astro-orbiter.
+# Default in defaults/main.yml is 1 (conservative). Bumped to 4 on 2026-08-12
+# (t_33acbb2e) so the router can keep more than one GGUF resident on-demand
+# and LRU-evict when needed.
+#
+# VRAM NOTE (t_33acbb2e, updated t_55c164f5, updated t_34b96e83, updated t_f5f7e9ad, updated t_441470b9, updated t_c5cef2b2):
+# With models-max=4 and all 6 GGUFs registered, worst case is all 6 loaded simultaneously:
+#   Qwen3.8-27B Q4_K_M:               ~20.0GB (weights ~17.1GB + KV ~2.9GB @ 65536 ctx, q4_0) ← CORRECTED (ctx rolled back from 128K to 65536, t_c9fed26c 2026-08-18)
+#   Phi-3.5-mini-instruct Q8_0:       ~4.3GB  (weights ~3.8GB + KV ~0.5GB @ 32K ctx)
+#   Meta-Llama-3.1-8B Q4_K_M:        ~5.6GB  (weights ~4.6GB + KV ~0.2GB @ 8K ctx)
+#   Qwen2.5-Coder-14B Q4_K_M:        ~9.0GB  (weights ~8.4GB + KV ~0.6GB @ 16K ctx)
+#   nomic-embed-text-v1.5 Q4_K_M:    ~0.09GB (~84MB, embedding only — no KV cache)
+#   Qwen3-8B Q4_K_M:                 ~5.5GB  (weights ~4.68GB + KV ~0.5GB @ 32K ctx, q4_0)
+#   Total worst-case:                 ~44.5GB  >>  24GB RTX 3090
+#
+# OOM RISK: Full co-residency is impossible on 24GB. LRU eviction prevents this
+# in practice: models-max=4 means the router can REGISTER 6 models but only keeps
+# up to 4 LOADED simultaneously — the router will evict the LRU model when a new
+# one is needed. nomic-embed-text-v1.5 is pinned via sleep-idle-seconds=-1 and
+# load-on-startup=true but it uses only ~84MB, so it never meaningfully changes
+# the budget. In single-user homelab operation, only one generative model is active
+# at a time alongside the always-resident embedding model.
+# Qwen3.8-27B alone uses ~17,804 MiB (weights+KV @ 65536 ctx); co-residency
+# with Coder (~9GB) = ~27GB > 24GB. LRU eviction handles this automatically.
+# Ryan should be aware this means model-switching always incurs a ~30-60s
+# cold-load latency when switching between Qwen3.8-27B and any other model.
+# Proceeding to models-max=4 as instructed; flagged for Ryan's attention.
+# Router --models-max override for astro-orbiter.
+# UPDATED (t_f5f7e9ad, 2026-08-16): Set to 2 because Qwen3.8-27B-Q4_K_M
+# uses 17,804 MiB at 65536 ctx. Only nomic-embed (558MB, pinned) and ONE
+# generative model can be resident simultaneously. Co-residency of Qwen3.8
+# with any auxiliary model (Phi 8.3GB, Llama 5.9GB, Coder 9GB) exceeds 24GB.
+# models-max=2: slot 1 = nomic-embed (pinned, always loaded), slot 2 = LRU
+# generative model (Qwen3.8 primary, cold-loaded on first request ~30-60s;
+# auxiliary models evict it on demand, and vice versa).
+# NOTE: Qwen3.8 does NOT have load-on-startup — it loads on first request.
+# This avoids an LRU eviction race with nomic-embed at startup.
+# UPDATED (t_72646029, 2026-08-17): CPU offload for Coder + Llama changes the
+# constraint. Coder and Llama now use CPU inference (n-gpu-layers=0). GPU-resident
+# VRAM: Qwen3.8 (~17,804 MiB at 65536 ctx) + nomic-embed (558 MiB, pinned) plus
+# the CUDA-context buffers llama.cpp 6ea215d allocates for the CPU models (~1.4-1.7GB
+# each) = ~20,004 MiB steady-state, below the 24,576 MiB physical limit.
+# CORRECTED (t_c5cef2b2, 2026-08-19): ctx-size was rolled back from 131072 to 65536
+# (t_c9fed26c 2026-08-18). Qwen3.8 VRAM at 65536: 17,804 MiB (not 20,302 MiB).
+# models-max raised to 4: nomic (slot 1, pinned) + Qwen3.8 (slot 2, GPU) +
+# Llama (slot 3, CPU) + Coder (slot 4, CPU). Phi (GPU, ~8.3GB) and new
+# Qwen3-8B (GPU, ~5.5GB) can also be requested but evict Qwen3.8 due to VRAM.

+#
+# Model choice: casperhansen/deepseek-r1-distill-qwen-32b-awq — same
+# quantizer/toolchain (AutoAWQ) as the outgoing Qwen2.5-32B-Instruct-AWQ,

+# support needed. Native max_position_embeddings=131072; we cap at 32768
+# per the task's explicit max-model-len requirement.
+#
+# VRAM math: ~19.3GB weights (4-bit AWQ) + KV cache at 32768 ctx (GQA,
+# 8 KV heads, 128 head_dim, 64 layers, fp16 KV by default) ≈ 19.3GB +
+# ~4GB KV+overhead ≈ 23.3GB — tight but the FULL 24GB card is now

+# the outgoing Qwen2.5-32B config). gpu_memory_utilization=0.95 (role
+# default) + enforce_eager retained as the proven-stable mitigation from
+# t_e6facb19/t_ca1af9fb (avoids CUDA graph capture VRAM spike; this host's
+# only validated way to avoid crash-loop-to-stabilize behavior on this
+# card). If 0.95 OOMs at 32768 ctx once tested live, drop to 0.90 next
+# (documented fallback, same pattern as the outgoing model).
+#
+# DeepSeek-R1 output note: reasoning traces stream in <think> tags before
+# the final answer — this is expected R1-distill behavior, not a bug.
+# Model card recommends temperature 0.5-0.7 (not 0, not vLLM's greedy

+# DESCRIPTION: Deploy llama-server in router mode on a shadow port (8003).
+#
+# This playbook deploys and validates the llama.cpp router mode supervisor on
+# astro-orbiter (10.1.71.130) WITHOUT touching the production endpoint
+# (llama-server-qwen, port 8002). All 7 dependent Hermes profiles
+# (bruce-banner, groot, happy, heimdall, rocket-raccoon, war-machine, wong)
+# remain pointing at port 8002 throughout this run.
+#
+# Usage (from ~/git/homelab/ansible):
+#   ansible-playbook -i inventory.yml playbooks/day1_deploy_llm_router_shadow.yml
+#
+# Tag-scoped runs (if you need to re-run one phase):
+#   ansible-playbook -i inventory.yml playbooks/day1_deploy_llm_router_shadow.yml \
+#     --tags router_systemd,router_firewall,router_verify
+#
+# Execution path (Ryan-approved 2026-08-12, task t_0cca74a2):
+#   Direct ansible-playbook as documented exception — Semaphore template for
+#   this role does not exist yet. Create template after cutover is confirmed.
+#   This is the same exception pattern used in prior sessions on this box.
+#
+# Pre-requisites:
+#   1. llama-server binary at /opt/llama.cpp/build/bin/llama-server supports
+#      router mode (confirmed 2026-08-12: --models-dir flag present in --help).
+#   2. /opt/models/ contains ONLY Qwen3.6-35B-A3B-UD-Q4_K_S.gguf
+#      (confirmed 2026-08-12: directory is clean, Phi-4/Mistral already deleted).
+#   3. Port 8002 is in use by the production llama-server-qwen service —
+#      this playbook does NOT touch it.
+#
+# Validation gates this playbook runs (all hard gates EXCEPT Gate 4):
+#   Gate 1: /v1/models reports Qwen with n_ctx >= 64000 (64K Hermes floor)
+#   Gate 2: Tool-calling probe through router returns finish_reason=tool_calls
+#   Gate 2b: Hallucination stress test does NOT trigger spurious tool_calls
+#   Gate 3: nvidia-smi VRAM <= 23,000 MiB (--models-max 1 confirmed effective)
+#   Gate 4: Bundled SvelteKit UI check (nice-to-have, non-blocking)
+#
+# What happens after this playbook:
+#   War Machine posts validation gate results to Ryan.
+#   Ryan reviews and signs off on cutover (or requests changes).
+#   War Machine then runs day2_cutover_qwen_to_router.yml (not yet created)
+#   to promote the router to port 8002 and retire the bare llama-server-qwen.

+#              on astro-orbiter (10.1.71.130:8002).
+#
+# Context (t_55c164f5, 2026-08-13):
+#   Ryan requested a Qwen2.5-Coder-14B-Instruct-Q4_K_M.gguf be added to the
+#   astro-orbiter router with:
+#     alias = "Qwen2.5-Coder-14B-Instruct-4bit"
+#     n_gpu_layers = 99
+#     ctx_size = 16384
+#     flash_attn = true
+#   Deployed GitOps-style via this role; no hand-editing of the live preset.
+#
+# What this playbook does:
+#   1. Downloads Qwen2.5-Coder-14B-Instruct-Q4_K_M.gguf into /opt/models if
+#      not already present (idempotent: size-check guard, no re-pull on match).
+#   2. Redeploys the preset INI (adding the [Qwen2.5-Coder-14B-Instruct-Q4_K_M]
+#      section with alias = Qwen2.5-Coder-14B-Instruct-4bit).
+#   3. Restarts llama-server-router to pick up the new model entry.
+#   4. Verifies /v1/models returns all 4 models including the new Coder entry.
+#
+# VRAM context note (t_55c164f5):
+#   Qwen2.5-Coder-14B Q4_K_M: ~8.4GB weights + ~0.6GB KV @ 16K ctx ≈ 9.0GB
+#   Qwen3.6-35B-A3B: ~21.5GB
+#   Full co-residency is impossible on 24GB. LRU eviction handles this:
+#   when Coder is requested, Qwen3.6-35B is evicted (and vice versa).
+#   Model-switching incurs ~30-60s cold-load latency — expected and acceptable.
+#   Phi (~4.3GB) or Llama (~5.6GB) can co-reside with Coder (total ~14GB).
+#
+# Usage (from ~/git/homelab/ansible):
+#   env -u ANSIBLE_VAULT_PASSWORD_FILE ansible-playbook -i inventory.yml \
+#     playbooks/day2_add_coder_alias.yml
+#
+# Semaphore note: Semaphore SSH key for jarvis user is not loaded in the
+# container (known pitfall, homelab-llm-serving skill). Run via CLI with

+# DESCRIPTION: Add nomic-embed-text-v1.5-Q4_K_M to the llama-server-router
+#              on astro-orbiter (10.1.71.130:8002).
+#
+# Context (t_34b96e83, 2026-08-13, OpenViking Phase 1b):
+#   Ryan approved adding nomic-embed-text-v1.5-Q4_K_M as an embedding model
+#   after Phase 0 follow-up confirmed embedding models fold cleanly into the
+#   existing router preset via embedding=true. Model ID is "nomic-embed-text-v1.5".
+#   No alias needed — peter-parker and Honcho consumers will call it by the section
+#   name directly.
+#
+# What this playbook does:
+#   1. Downloads nomic-embed-text-v1.5-Q4_K_M.gguf into /opt/models if not
+#      already present (idempotent: exact size-check guard, no re-pull on match).
+#   2. Redeploys the preset INI (adding the [nomic-embed-text-v1.5] section with
+#      embedding=true, n-gpu-layers=99, ctx-size=8192, load-on-startup=true,
+#      sleep-idle-seconds=-1).
+#   3. Restarts llama-server-router to pick up the new model entry.
+#   4. Verifies /v1/models returns all 5 models including the new nomic entry.
+#   5. Runs a /v1/embeddings smoke test to confirm the model actually embeds.
+#
+# VRAM context note (t_34b96e83):
+#   nomic-embed-text-v1.5 Q4_K_M: ~84MB weights, embedding model (no KV cache).
+#   VRAM impact is negligible — always pinned via sleep-idle-seconds=-1.
+#   The 4 generative models remain unchanged (OOM analysis unchanged from t_55c164f5).
+#
+# Usage (from ~/git/homelab/ansible):
+#   env -u ANSIBLE_VAULT_PASSWORD_FILE ansible-playbook -i inventory.yml \
+#     playbooks/day2_add_nomic_embed.yml

+#
+# Context (t_9adf0889, 2026-08-12):
+#   Ryan's Hermes config (auxiliary.title_generation.model) points to

+#   This playbook adds the alias so both names work without changing Ryan's
+#   Hermes config.
+#
+# What this playbook does:
+#   1. Deploys the preset INI template (llama-server-router-preset.ini.j2)
+#      to /opt/llama-server-router-preset.ini on astro-orbiter.
+#   2. Redeploys the systemd unit (llama-server-router.service) with
+#      --models-preset instead of --models-dir.
+#   3. Restarts llama-server-router to pick up the new flag.
+#   4. Verifies that /v1/models returns:
+#      - Phi-3.5-mini-instruct-Q8_0 (original ID — must still work)
+#      - Phi-3.5-mini-instruct-8bit (new alias — Ryan's config target)

+#      - Meta-Llama-3.1-8B-Instruct-Q4_K_M (unchanged)
+#
+# Known upstream behavior:

+# FILE: playbooks/day2_bump_router_models_max.yml
+# DESCRIPTION: Bump --models-max on the production llama-server-router unit.
+#
+# Context: t_33acbb2e (2026-08-12) — Ryan requested --models-max raised from 1
+# to 4 so the router can keep multiple GGUFs resident on-demand (LRU eviction
+# when the cap is reached). The actual var change lives in:
+#   host_vars/astro-orbiter/vars.yml  (llm_router_models_max: 4)
+#
+# This playbook:
+#   1. Re-renders llama-server-router.service.j2 with the updated var value.
+#   2. Reloads systemd (daemon-reload handler) if the unit changed.
+#   3. Restarts llama-server-router so the new --models-max takes effect on the
+#      live process. Router holds no resident model (all-unloaded) so restart
+#      is sub-second and non-disruptive.
+#   4. Verifies /health returns 200 and /v1/models still lists all three GGUFs.
+#
+# VRAM NOTE: --models-max 4 allows up to all 3 current GGUFs to co-reside on
+# a 24GB card simultaneously. Worst-case combined footprint is ~31GB which
+# EXCEEDS 24GB — OOM is possible if all 3 are loaded concurrently. In normal
+# single-user homelab operation this is very unlikely. Full VRAM breakdown
+# documented in host_vars/astro-orbiter/vars.yml. Ryan approved (t_33acbb2e).
+#
+# Execution channel: Semaphore template "llm_router_update_unit" (project mk-labs).
+# Do NOT run via direct ansible-playbook or ad-hoc ssh/systemctl.

+#           astro-orbiter's production router (port 8002).
+#
+# What this playbook does:
+#   1. Re-renders llama-server-router-preset.ini (Coder + Llama sections now
+#      use per-model n-gpu-layers vars = 0 -> full CPU inference).
+#   2. Re-renders the router unit (--models-max now 4 via host_vars, global
+#      --n-gpu-layers removed per t_72646029 unit template fix) and restarts
+#      llama-server-router so both changes take effect.
+#   3. Verifies per the role's router_preset phase.
+#
+# Context (2026-08-17):
+#   - RAM/model-swap audit, TIER 1 (Coder-14B CPU offload) + TIER 2
+#     (Llama-3.1-8B CPU offload) — Ryan approved 1 & 2 on 2026-08-17.
+#     See inbox/ryan/2026-08-17-llm-system-ram-model-swap.md.
+#   - Unit template fix (t_72646029): global --n-gpu-layers removed from
+#     ExecStart in preset mode. Each INI section now sets n-gpu-layers
+#     explicitly (Qwen3.8=99, Phi=99, nomic=99, Coder=0, Llama=0).
+#   - Concurrent residency after change: Qwen3.8-27B (20,302 MiB @ 128K ctx)
+#     + nomic-embed (558 MiB, pinned) + Coder (CPU, ~1,390 MiB CUDA ctx) +
+#     Llama (CPU, ~1,706 MiB CUDA ctx) = ~24,004 MiB. NOTE: llama.cpp 6ea215d
+#     allocates CUDA-context VRAM even at n-gpu-layers=0, so CPU models are not
+#     0-VRAM; total sits at the 24,576 MiB physical limit (headroom ~572 MiB).
+#     Qwen3.8 is never evicted for a CPU aux model; Phi-3.5-mini (GPU, 8.3GB)
+#     still evicts as before.
+#   - CPU speed (8-core Ryzen 7 5800XT): ~5-10 tok/s (14B), ~10-20 tok/s (8B).
+#   - Semaphore SSH gap for astro-orbiter still applies (t_730f9584 /

+#   PASS, VRAM 20410 MiB / 1 process). Ryan approved cutover.

+# This playbook makes the router the permanent production endpoint:

+#   1. Stop + disable llama-server-qwen (:8002). Unit file is PRESERVED on disk
+#      as the rollback target (same pattern as prior role history).
+#   2. Redeploy llama-server-router unit file with --port 8002 (production port).
+#      PORT DECISION: we rebind the router to :8002 rather than updating 8
+#      dependent Hermes profiles' base_url. One unit file change beats 8
+#      config.yaml updates — atomic, GitOps-clean, zero profile drift.
+#   3. Enable + start llama-server-router on :8002.
+#   4. Re-run validation gates 1-3 against the NOW-production endpoint.
+#      (Same logic as Phase R / router_verify in tasks/router.yml — hard gates.)
+#   5. Run Gate 4: verify bundled SvelteKit UI is reachable.

+# DESCRIPTION: Right-size --ctx-size per model workload on llama-server-router
+#              (already in --models-preset mode since t_9adf0889).
+#
+# Context (t_ryan_per_model_ctx, 2026-08-13, requested by Ryan via JARVIS):
+#   All 3 preset models currently launch with a uniform --ctx-size 65536.
+#   This playbook narrows two of them to match actual workload:
+#     - Meta-Llama-3.1-8B-Instruct-Q4_K_M (alias Meta-Llama-3.1-8B-Instruct-4bit):
+#         ctx-size 65536 -> 8192  (tool-routing / micro-tasks: title gen, MCP
+#         tool calls, approval checks)
+#     - Phi-3.5-mini-instruct-Q8_0 (alias Phi-3.5-mini-instruct-8bit):
+#         ctx-size 65536 -> 32768 (long web scrapes / session-log compression)
+#   Both also move flash-attn from "auto" to explicit "true" per Ryan's spec.
+#   Qwen3.6-35B-A3B-UD-Q4_K_S is INTENTIONALLY left untouched at 65536/auto.
+#
+#   Existing aliases (Meta-Llama-3.1-8B-Instruct-4bit, Phi-3.5-mini-instruct-8bit)
+#   are PRESERVED as-is. Ryan's pasted TOML used different alias strings
+#   ("llama-3.1-8b", "phi-3.5-mini") but renaming aliases was not explicitly
+#   requested and would break live Hermes custom_providers routing — flagged
+#   in the deployment report rather than applied silently.
+#
+# IMPORTANT — Hermes side effect: /home/hermes/.hermes/config.yaml declares
+# context_length: 65536 for both these models under custom_providers. This
+# playbook does NOT touch that file (out of role/agent scope) but the value
+# becomes STALE the moment this playbook lands. Flag to JARVIS/Maria Hill.
+#
+# Usage (from ~/git/homelab/ansible):
+#   ansible-playbook -i inventory.yml playbooks/day2_per_model_ctx_size.yml

+#
+# Context:
+#   - t_441470b9 (2026-08-16): ctx-size bumped 32768 -> 131072. Verified VRAM
+#     at 131072 ctx with only Qwen3.8 + nomic-embed co-resident: ~20,282 MiB
+#     + 558 MiB = ~20.8 GB on 24 GB RTX 3090. Comfortably safe.
+#   - t_72646029 (2026-08-17): Phi-3.5mini moved to GPU (n-gpu-layers=99)
+#     to enable concurrent residency with CPU-offloaded Coder-14B and
+#     Llama-3.1-8B. This added ~2GB CUDA context buffers for Phi + shifted
+#     Phi's model weights onto the GPU (~3.8GB).
+#   - NEW steady-state VRAM: Qwen3.8 @ 131072 ctx (~20,282 MiB) + nomic-embed
+#     (~558 MiB) + Llama CUDA ctx (~1,706 MiB) + Coder CUDA ctx (~1,390 MiB)
+#     = ~24,004 MiB. Adding Phi-3.5 (~3,800 MiB weights + ~1.4 GB CUDA ctx)
+#     pushes total to ~29,000+ MiB — exceeding the 24,576 MiB RTX 3090 limit.
+#     Qwen3.8-27B-131072 now fails to load (HTTP 500, OOM before llama.cpp
+#     reaches the model-loading phase).
+#   - FIX: reduce Qwen3.8 ctx-size 131072 -> 65536. This reduces KV cache
+#     from ~6GB to ~3GB, freeing ~3GB of VRAM. New estimated steady-state:
+#     Qwen3.8 @ 65536 ctx (~17,068 MiB) + nomic (~558) + Llama ctx (~1,706)
+#     + Coder ctx (~1,390) + Phi-3.5 (~3,800 + ~1,400 CUDA ctx) = ~25,922 MiB.
+#     Still over 24,576 — see "Phase 2" below for the secondary fix.
+#
+#   IMPORTANT: Rolling back ctx-size alone may NOT be sufficient. The
+#   hardware reference (astro-orbiter-hardware.md line 166, t_72646029)
+#   states steady-state ~24,004 MiB WITHOUT Phi on GPU. Adding Phi-3.5 back
+#   to GPU tips it over. This playbook handles the context rollback; if Qwen3.8
+#   still fails to load after Phase R, Wong should escalate to Ryan for a
+#   decision on either (a) offloading Phi-3.5mini to CPU (n-gpu-layers=0),
+#   or (b) adding a second GPU. Document the Phase 2 finding as a separate
+#   follow-up task if needed.
+#
+#   The 64K floor from the 2026-08-12 cutover validation (t_cd0d5388, Gate 1)
+#   still applies — ctx-size=65536 satisfies it.

+Installs [Claude Code](https://code.claude.com/docs/en/setup) on Ubuntu 20.04+ / Debian 10+ (x64 or ARM64, 4 GB+ RAM).
+
+## Methods
+
+| `claude_code_install_method` | What it does | Updates |
+|---|---|---|
+| `apt` (default) | Adds Anthropic's signed apt repo (stable or latest channel) and installs the `claude-code` package system-wide. Verifies the signing-key fingerprint before trusting it. | `apt upgrade` / set `claude_code_package_state: latest` |
+| `native` | Runs Anthropic's installer as `claude_code_user`; binary lands in `~/.local/bin/claude`. | Self-updates in the background |
+
+## Key variables (see `defaults/main.yml`)
+
+- `claude_code_apt_channel`: `stable` (about a week behind, skips bad releases) or `latest`
+- `claude_code_package_state`: `present` or `latest`
+- `claude_code_native_version`: `latest`, `stable`, or a pinned version like `2.1.89`
+- `claude_code_settings`: optional dict written to `~/.claude/settings.json` (overwrites the file)
+
+## Use
+
+```bash
+cp inventory.ini.example inventory.ini   # edit hosts
+ansible-playbook -i inventory.ini install-claude.yml --check   # dry run
+ansible-playbook -i inventory.ini install-claude.yml
+```
+
+The remote user needs sudo for the `apt` method.
+
+## After install: authenticate (not automated)
+
+Run `claude` once on the server and follow the login prompt, or export `ANTHROPIC_API_KEY`
+for the user (store it in Ansible Vault, not in the repo). A Pro, Max, Team, Enterprise or
+Console account is required; the free claude.ai plan does not include Claude Code.
+
+Verify with `claude --version` and `claude doctor`.

+Idempotent Ansible role that deploys a vLLM OpenAI-compatible inference
+server. Written for astro-orbiter (RTX 3090, 24GB VRAM, 64GB RAM, Ubuntu
+24.04) and designed for reuse on the planned Mac Mini M4 host later this
+week (see "Portability" below).
+
+Supersedes the manual, pre-role state left behind by earlier vLLM
+experiments (`/home/jarvis/vllm-env`, bitsandbytes, gemma-2-27b — see
+`homelab-llm-inference`/`homelab-llm-serving` skills for that history). This
+role uses a **fresh venv** (`vllm_venv_path`, default `~/vllm-serve-env`) and
+**AWQ pre-quantized models** — no bitsandbytes, no on-the-fly quantization,
+no repeat of the OOM incident from the earlier Gemma-2-27B attempt.
+
+## Phases
+
+| Phase | File | What it does |
+|---|---|---|
+| 1 | `tasks/dependencies.yml` | System Python 3.10+, dedicated venv, `pip install vllm>=0.5.0`, verifies `nvidia-smi` and `torch.cuda.is_available()` |
+| 2 | `tasks/models.yml` | Downloads each `enabled: true` model in `vllm_models` via `hf download` (huggingface_hub CLI) into `~/.vllm-cache`, verifies the snapshot landed and reports on-disk size |
+| 3 | `tasks/api-key.yml` | Reads the API key from 1Password (`op://mk-labs/vllm/api-key`) on the **controller**, writes it to `/etc/vllm/api-key.env` (root:root, 0600) on the target |
+| 4 | `tasks/systemd.yml` | Renders and installs one systemd unit per enabled model (`vllm.service` for the `role: primary` model, `vllm-<id>.service` for others) |
+| 5 | `tasks/verify.yml` | Only runs when `vllm_service_state=started`. Waits for `/health` (up to 5 min — torch.compile warmup), checks `/v1/models`, runs a live completion, scans `journalctl` for errors |
+
+Run all phases: `ansible-playbook -i inventory.yml playbooks/day1_deploy_vllm.yml --limit astro-orbiter`
+Run one phase: `--tags vllm-dependencies` / `vllm-models` / `vllm-api-key` / `vllm-systemd` / `vllm-verify`
+
+## Deliberate staging-first default
+
+`vllm_service_state` defaults to `stopped`. A default run **stages
+everything** (venv, model weights, API key file, systemd unit) but does
+**not** start the service or touch production traffic. This matches the
+astro-orbiter cutover plan: llama-swap is live production serving (Qwen3.8-27B
++ nomic-embed for Hindsight) — vLLM must be deployed and validated on a
+side port/inactive unit before anything is cut over.
+
+To start and validate:
+
+```bash
+ansible-playbook -i inventory.yml playbooks/day1_deploy_vllm.yml \
+  --limit astro-orbiter --extra-vars "vllm_service_state=started"
+```
+
+This starts the systemd unit(s), enables them, and runs Phase 5 verification
+(health, `/v1/models`, live completion, clean journalctl).
+
+**Cutover of consumers (Hermes profiles, Hindsight embedding config, any
+hardcoded `:8001`/`:5805` references) to the new `:8000` vLLM endpoint is a
+separate, explicit step outside this role** — do this only after Phase 5
+passes cleanly. Do not tear down llama-swap until consumers are confirmed
+working end-to-end against vLLM.
+
+## Model roster (`vllm_models` in defaults/main.yml)
+
+vLLM 0.5.x-0.28.x serves **one model per process** — multi-model = multiple
+systemd units on distinct ports, not a single multiplexed server (unlike
+llama-swap's matrix DSL). Today's phase enables only the primary model;
+flip `enabled: true` on the others as VRAM allows (see "Phased Strategy"):
+
+**⚠️ Table below reflects the ORIGINAL Qwen2.5-32B deployment. As of
+2026-09-01 (t_r1d32b_swap) the primary model is
+`DeepSeek-R1-Distill-Qwen-32B-AWQ`, single-model only (nomic-embed also
+disabled) — see the "SUPERSEDED" section further down for current state.**
+
+| id | hf_repo | role | port | quant | enabled |
+|---|---|---|---|---|---|
+| Qwen2.5-32B-Instruct-AWQ | Qwen/Qwen2.5-32B-Instruct-AWQ | primary | 8000 | awq | **true** |
+| Qwen3-8B-AWQ | Qwen/Qwen3-8B-AWQ | aux | 8010 | awq | false |
+| nomic-embed-text-v1.5 | nomic-ai/nomic-embed-text-v1.5 | embedding | 8020 | none | false |
+
+**Note on the original spec's model choices:** the task body named
+`Qwen/Qwen2.5-32B-Instruct` and `Qwen/Qwen3-8B-Instruct` (bf16, unquantized).
+vLLM does not do on-the-fly quantization safely on this host (bitsandbytes
+OOM history — see `homelab-llm-inference` skill Pitfalls) and unquantized
+bf16 32B does not fit a 24GB card at all (~65GB). This role instead deploys
+the **official Qwen AWQ pre-quantized variants**
+(`Qwen/Qwen2.5-32B-Instruct-AWQ`, `Qwen/Qwen3-8B-AWQ`), which vLLM natively
+supports (`--quantization awq`) and which fit the VRAM budget:
+
+- Qwen2.5-32B-Instruct-AWQ: ~19.3GB on disk, fits with ~5GB headroom at 24GB
+- Qwen3-8B-AWQ: ~6GB VRAM per llm-explorer
+- nomic-embed-text-v1.5: ~300MB, vLLM serves it via `--convert embed` pooling
+  (see vLLM embedding docs) — **not yet wired into this role's systemd
+  template**; the embedding model needs `--task embed` / `--convert embed`
+  flags that differ from the completion-serving template. Flagged as a
+  follow-up before `enabled: true` is flipped on it (see Known Gaps below).
+
+## Known Gaps / Follow-ups
+
+- Quarterly API key rotation is documented (`/etc/vllm/API_KEY_ROTATION.md`
+  on the target, rendered by `tasks/api-key.yml`) but not automated — no cron
+  job exists to force rotation on a schedule. Consider a follow-up cron task
+  if Nick Fury wants this enforced rather than just documented.
+- `vllm_service_enabled` defaults to `false` deliberately — see "Deliberate
+  staging-first default" above. Flip together with the cutover step, not
+  before.
+- **vLLM cannot replace llama-swap's full model roster on this card — see
+  "Critical architectural finding" section below for the full incident.**
+  Short version: vLLM's one-model-per-process design plus llama-swap's own
+  VRAM needs exceed this 24GB card's capacity when both must serve real
+  models simultaneously. Full llama-swap teardown (t_6dff1ecc) cannot
+  proceed until a human decides the aux-model + VRAM strategy.
+
+## Embedding-mode support (t_e6facb19, 2026-08-31)
+
+`vllm.service.j2` now branches on `role: embedding` entries in `vllm_models`:
+adds `--runner pooling --convert embed` (vLLM's embedding-serving flags —
+see https://docs.vllm.ai/en/latest/models/pooling_models/embed/) and
+`--no-enable-prefix-caching` (prefix caching is a completions-only
+optimization; irrelevant and safely disabled for pooling). An additional
+per-model `trust_remote_code: true` toggle renders `--trust-remote-code`
+when set — required for `nomic-ai/nomic-embed-text-v1.5`, which ships
+custom `NomicBertModel` modeling code on its HF repo.
+
+**Verification does NOT run `/v1/completions` against embedding-mode
+instances** (they don't serve that endpoint — a completions request 400s
+immediately). `tasks/verify.yml` splits `vllm_enabled_models` by `role` and
+runs the appropriate smoke test per group: completions models get the
+`/v1/completions` "capital of France" test; embedding models get a real
+`/v1/embeddings` POST with an `ansible.builtin.assert` on a non-empty
+`data[0].embedding` array (not just HTTP 200 — an empty/malformed vector
+would still 200).
+
+**Critical VRAM finding: co-resident completions + embedding vLLM processes
+need MORE headroom than either alone, and CUDA graph capture is the failure
+mode, not KV cache sizing.** Enabling `nomic-embed-text-v1.5` alongside the
+primary Qwen2.5-32B model at the role-default `gpu_memory_utilization: 0.95`
+crash-looped repeatedly:
+- First failure: `torch.OutOfMemoryError` during `capture_model()` (CUDA
+  graph capture) — KV cache sizing itself succeeded (14,720 tokens
+  allocated), but graph capture needed ~20MiB more than the 0.95 budget had
+  left once nomic's embedding process (814MiB actual, not the nominal
+  ~300MB estimate in the model roster table) claimed its share.
+- Fix attempt 1: added a per-model `enforce_eager: true` template branch
+  (`--enforce-eager` skips CUDA graph capture entirely) — this stopped the
+  graph-capture OOM but the combined processes still landed at only
+  ~847MiB genuinely free out of 24,576MiB, and both services crash-looped
+  6-7 times during warmup before finally stabilizing (each attempt leaves
+  transient VRAM that the next attempt fights over, extending time-to-stable
+  well past a single health-check retry window).
+- Fix attempt 2 (final, verified stable): lowered the primary model's
+  `gpu_memory_utilization` from 0.95 to **0.90** (host_vars override) in
+  addition to `enforce_eager: true`. Result: clean single-attempt start for
+  both services, `NRestarts=0`, ~2GB genuinely free (22,577MiB used /
+  24,576MiB total). Confirmed via `systemctl show <unit> -p NRestarts` after
+  a full stop/start cycle — 0.95 was NOT a fluke of Restart=always masking
+  the underlying fragility; 0.90 is a real, reproducible fix.
+- **Takeaway for future multi-process vLLM VRAM budgeting on this host:**
+  do not just check "does it eventually come up" — check `NRestarts` and
+  free VRAM headroom after a clean stop/start. A model that "works" after
+  6 crash-loop retries is not production-stable; the retries themselves are
+  evidence the utilization ceiling is too tight for the actual (not
+  nominal) footprint of co-resident processes.
+
+## Consumer cutover status (t_e6facb19, 2026-08-31)
+
+**Attempted, then REVERTED — Hindsight LLM cutover.** Hindsight's
+`HINDSIGHT_API_LLM_BASE_URL` was pointed at vLLM `:8000`
+(Qwen2.5-32B-Instruct-AWQ) and validated working in isolation: health,
+`/v1/chat/completions`, and a live `hindsight_retain` + recall round-trip
+all succeeded (after also fixing `HINDSIGHT_API_RETAIN_MAX_COMPLETION_TOKENS`,
+which defaulted to 64000 — exceeding vLLM's `max_model_len=8192` — down to
+4096). **Reverted anyway**, because of a severe discovery documented in the
+next section: vLLM cannot stay resident on this card without starving
+llama-swap, and Hindsight's LLM endpoint needs continuous availability, not
+just a validation window. Restored to `http://astro-orbiter:8001/v1`
+(llama-swap, Qwen3.8-27B-Q4_K_M) — the pre-task working state.
+
+**NOT cut over — embeddings.** Hindsight was discovered to have NEVER used
+astro-orbiter for embeddings — it defaults to a bundled local
+`BAAI/bge-small-en-v1.5` (384-dim) embedder whenever
+`HINDSIGHT_API_EMBEDDINGS_PROVIDER` is unset, which was always the case here.
+Pointing it at vLLM's `nomic-embed-text-v1.5` (768-dim) crash-looped the pod:
+`RuntimeError: Cannot change embedding dimension from 384 to 768:
+memory_units table contains 1289 rows with embeddings.` Re-embedding all
+existing memory data across ~20 agent banks is destructive and irreversible
+— reverted immediately, left as a separate, explicitly-approved future task.
+
+**NOT cut over — 21 Hermes agent profiles' aux models + OpenViking VLM.**
+See "Critical architectural finding" below — this was never attempted once
+the VRAM collision was discovered, would have made things categorically
+worse.
+
+## Critical architectural finding: vLLM CANNOT be continuously resident alongside llama-swap on this 24GB card (t_e6facb19, 2026-08-31)
+
+After validating vLLM's two processes (Qwen2.5-32B-Instruct-AWQ + nomic-embed-
+text-v1.5, ~22.8GB combined) work correctly in isolation, this role's
+`vllm_service_enabled`/`vllm_service_state` were flipped to `true`/`started`
+as host_vars overrides to make the deployment permanent (per the task's
+"enable for boot" requirement) — llama-swap was then restarted alongside
+vLLM to preserve its own consumers. **Result: llama-swap could no longer
+load ANY of its own generative models.** Every `/v1/chat/completions`
+request against `Qwen3.8-27B-Q4_K_M` or the `Qwen3-8B` aux models failed
+with `{"error":"unspecific error: upstream command exited prematurely",
+"src":"llama-swap"}` — llama-server's own OOM at spawn time, only ~1.8GB
+free on a 24GB card once vLLM's ~22.8GB was already claimed.
+
+**Confirmed by direct A/B test, not inference:** identical
+`Qwen3.8-27B-Q4_K_M` chat completion request returned HTTP 500 with vLLM's
+two processes running, then HTTP 200 with a real completion within seconds
+of `systemctl stop vllm.service vllm-nomic-embed-text-v1.5.service` — same
+llama-swap process, same request, only the GPU memory pressure changed.
+
+**This is a hard architectural collision, not a tunable-parameter problem.**
+llama-swap needs ~18-20GB for its own primary model (Qwen3.8-27B-Q4_K_M);
+vLLM's two processes need ~22.8GB even with `enforce_eager` and a lowered
+`gpu_memory_utilization`. The two together need more VRAM than a 24GB card
+has once both hold real models resident — there is no `gpu_memory_utilization`
+value that resolves this while both stacks serve real production models
+simultaneously.
+
+**Consequence — reverted the boot-persistence flip.** `vllm_service_enabled`
+and `vllm_service_state` are back to role defaults (`false`/`stopped`) in
+`host_vars/astro-orbiter/vars.yml`. vLLM stays staged (venv, model weights,
+systemd units all in place) and can be started for a brief shadow-validation
+window (same pattern as t_ca1af9fb's original Phase 5), but is NOT safe to
+leave resident in production alongside llama-swap.
+
+**Path forward — requires a human decision, not more role tuning:**
+1. Full llama-swap teardown (t_6dff1ecc) BEFORE vLLM gets permanent
+   residency — but that breaks the 21 agent profiles' aux-model tasks and
+   OpenViking's VLM unless those consumers are migrated to a different
+   backend first (Anthropic API, a second smaller local box, or a
+   redesigned single-process serving strategy that covers all the models
+   vLLM and llama-swap currently split between them).
+2. Accept vLLM as a shadow-only / on-demand stack (manually started for
+   specific validated windows, stopped otherwise) and do NOT attempt
+   permanent Hindsight cutover — keeps llama-swap as the sole continuous
+   production serving layer, matching the pre-task state.
+3. A hardware change (larger GPU, or a second GPU) — out of scope for this
+   task, flagging for Ryan's awareness if the aux-model consumer set is
+   expected to grow.
+
+Comment posted on t_6dff1ecc with this finding — the teardown task remains
+correctly blocked; this task's completion does NOT unblock it, because full
+cutover to vLLM is not achievable within this card's VRAM budget as
+currently scoped.
+
+## RESOLVED (t_5508360a, 2026-08-31/09-01): Dashboard decision applied — llama-swap retired, vLLM permanent, 2 of 3 models
+
+Human decision (dashboard, kanban t_5508360a): **"stop and disable llama-swap
+and start vLLM and its 3 models"** — explicit approval, "I understand this is
+a breaking change." Chose path 1 from the three options above: retire
+llama-swap, give vLLM permanent residency, accept that the 21 Hermes
+profiles' aux-model consumers lose their llama-swap aux roster (Qwen3-8B,
+Phi-3.5-mini, Meta-Llama-3.1-8B, Qwen2.5-Coder-14B — all 4 gone) in exchange
+for vLLM's stack. Mid-run the dashboard added a course-correction: **"Don't
+try to load all 3 models concurrently on first deploy. Start with
+Qwen2.5-32B only"** — received after the 3-model attempt below had already
+run and self-corrected to the same 2-model end state, so no further action
+needed, but noted for the record.
+
+**Executed:**
+1. `sudo systemctl stop llama-swap && sudo systemctl disable llama-swap` on
+   astro-orbiter — confirmed inactive+disabled, VRAM dropped to 9MiB/24576MiB
+   (from 20.6GB in production use).
+2. Flipped `vllm_service_enabled`/`vllm_service_state` to `true`/`started` in
+   `host_vars/astro-orbiter/vars.yml` — vLLM is now the permanent,
+   boot-persistent serving layer (was shadow-only/staged before this task).
+3. **Attempted the literal "3 models" instruction** — flipped
+   `Qwen3-8B-AWQ.enabled` to `true` too. **Does not fit.** With the 24GB
+   card's usable 23.55GiB budget consumed by Qwen2.5-32B-Instruct-AWQ
+   (~18.6GB weights) + nomic-embed-text-v1.5 (~0.8GB actual), only ~1.25GiB
+   remained free — below the 3.53GiB floor `gpu_memory_utilization=0.15`
+   requires for Qwen3-8B-AWQ even with `enforce_eager`. Confirmed via
+   `journalctl`: identical `ValueError: Free memory on device cuda:0
+   (1.25/23.55 GiB) on startup is less than desired GPU memory utilization`
+   on all 7 consecutive systemd restart attempts — not the transient
+   CUDA-graph-capture crash-loop t_e6facb19 solved with enforce_eager, a hard
+   ceiling. Stopped + disabled `vllm-Qwen3-8B-AWQ.service`, reverted
+   `enabled: false` in host_vars with a full writeup in the comment block.
+4. Re-ran `day1_deploy_vllm.yml --extra-vars vllm_service_state=started`
+   with the corrected 2-model config: **clean idempotent pass, changed=0** on
+   both remaining models, Phase 5 verification passed (`/health` 200 on both
+   `:8000` and `:8020`, `/v1/models` correct, live completion + live
+   embeddings smoke tests both passed), `NRestarts=0` on both services.
+5. **Cut over Hindsight's LLM endpoint** (the other production consumer):
+   `HINDSIGHT_API_LLM_BASE_URL` llama-swap `:8001` → vLLM `:8000`,
+   `HINDSIGHT_API_LLM_MODEL` → `Qwen2.5-32B-Instruct-AWQ`, added
+   `HINDSIGHT_API_RETAIN_MAX_COMPLETION_TOKENS=4096` (vLLM's
+   `max_model_len=8192` vs Hindsight's 64000 default), and switched the
+   ExternalSecret's `HINDSIGHT_API_LLM_API_KEY` source from the unused
+   `nous` 1Password item to `vllm`'s real `api-key` (vLLM validates its
+   bearer token; llama-swap never did). Committed to
+   `cluster/applications/hindsight/{values.yaml,externalsecret.yaml}`,
+   pushed, ArgoCD synced, confirmed the new pod logged `Connection verified:
+   openai/Qwen2.5-32B-Instruct-AWQ` on boot.
+6. **Live end-to-end verification**, not inference: a real
+   `POST /v1/default/banks/war-machine/memories` retain call against the
+   production Hindsight endpoint returned `HTTP 200` with genuine
+   fact-extraction token usage (3257 in / 245 out), and a subsequent
+   `POST .../memories/recall` returned real semantically-ranked results
+   including the just-retained memory.
+
+**Final production state on astro-orbiter (verified live):**
+- `vllm.service` (Qwen2.5-32B-Instruct-AWQ, :8000): active, enabled, boot-persistent
+- `vllm-nomic-embed-text-v1.5.service` (:8020): active, enabled, boot-persistent
+- `vllm-Qwen3-8B-AWQ.service` (:8010): inactive, disabled — does not fit, see above
+- `llama-swap.service`: inactive, disabled (unit files left in place —
+  full removal is t_6dff1ecc's job, tracked separately)
+- VRAM: ~22.6GB/24.576GB in steady-state use, no crash-looping
+
+**What this means for t_6dff1ecc (teardown) and the 21 aux-model profiles:**
+llama-swap is now stopped+disabled — t_6dff1ecc's actual teardown steps
+(remove systemd unit files, wipe caches) are now safe to execute and
+unblocked from a "live production" standpoint. However, this trades away
+the aux-model roster: the 21 Hermes profiles' aux-model tasks (skills_hub,
+approval, mcp, title_generation, profile_describer, compression) that
+used to route to llama-swap's Qwen3-8B/Phi-3.5-mini/Meta-Llama/Coder
+models now have **zero local aux-model backend** — Qwen3-8B-AWQ doesn't
+fit vLLM's VRAM budget either. This was accepted explicitly by the
+dashboard ("I understand this is a breaking change") — no further local
+aux-model migration was authorized or attempted in this task. If those 21
+profiles need a replacement aux-model path, that is separate, new,
+explicitly-scoped follow-up work, not implied by this decision.
+
+## SUPERSEDED (t_r1d32b_swap, 2026-09-01): Qwen2.5-32B-Instruct-AWQ retired, replaced with DeepSeek-R1-Distill-Qwen-32B-AWQ, single-model deployment
+
+Ryan direction: "Swap Qwen2.5-32B for DeepSeek-R1-Distill-Qwen-32B,
+max-model-len 32768. Single model only." Confirmed with Ryan that "single
+model only" includes disabling `nomic-embed-text-v1.5` (:8020) as well —
+nothing in production consumed it (Hindsight uses its own bundled 384-dim
+embedder; OpenViking pointed at the retired llama-swap endpoint). DeepSeek
+gets the entire 24GB card.
+
+**Model choice:** `casperhansen/deepseek-r1-distill-qwen-32b-awq` — same
+AutoAWQ toolchain/quant style as the outgoing Qwen2.5-32B-Instruct-AWQ,
+widely-used community quant, `Qwen2ForCausalLM` architecture (DeepSeek-R1
+reasoning distilled onto a Qwen2.5-32B base) — no new vLLM code path
+required. Native `max_position_embeddings: 131072`; capped at 32768 per
+the task's explicit requirement.
+
+**Executed:**
+1. Stopped + disabled `vllm-nomic-embed-text-v1.5.service` (single-model
+   requirement), freed its ~19GB Qwen2.5-32B model cache on disk (30GB
+   free → 48GB free) to make room for DeepSeek's ~19.3GB download.
+2. Replaced `vllm_models` in `host_vars/astro-orbiter/vars.yml`: primary
+   entry now `DeepSeek-R1-Distill-Qwen-32B-AWQ`, aux (`Qwen3-8B-AWQ`) and
+   embedding (`nomic-embed-text-v1.5`) both `enabled: false`.
+3. Staged the model via `--tags vllm-models` (idempotent `hf download`,
+   ~19GB, confirmed via `du -sh` and snapshot-dir stat).
+4. **Three rounds of live VRAM-fit debugging** before a stable config was
+   found (documented inline in host_vars comments) — worth recording here
+   since the failure mode is non-obvious and will recur for future
+   32B-class models at high context on this 24GB card:
+   - **Round 1 (fp16 KV, gpu_memory_utilization 0.90/0.95/0.98):** vLLM's
+     own pre-flight check reported 18.17GiB weights + 8.0GiB KV cache
+     needed at 32768 ctx fp16 = 26.17GB — mathematically impossible on a
+     24GB card at ANY utilization percentage. Crash-looped every attempt.
+   - **Round 2 (`--kv-cache-dtype fp8`):** halved nominal KV cache to
+     ~4.0-4.3GiB, should fit with ~1GB margin. Still OOM'd — small
+     (~50-150MB) `cudaMalloc` failures during FlashInfer kernel warmup,
+     consistently, even when vLLM's own pre-flight math said it should
+     fit. Root cause: real GPU usage during warmup kernel compilation
+     exceeds what upfront profiling/reservation accounts for by roughly
+     ~1GB (unaccounted FlashInfer/sampler warmup workspace buffers).
+     Tried both the percentage knob AND vLLM's own suggested
+     `--kv-cache-memory-bytes` exact value — same failure either way,
+     confirming the gap wasn't a rounding/estimation error in the
+     percentage math, it was a real missing ~1GB of margin.
+   - **Round 3 (`--kv-cache-dtype int4_per_token_head`, fixed): SUCCESS.**
+     Switching from 8-bit to 4-bit KV cache roughly halves the KV
+     footprint again (~2GiB instead of ~4-4.3GiB), buying back enough
+     real headroom to absorb the unaccounted warmup overhead. Clean
+     single-attempt start, `NRestarts=0`, steady-state VRAM 23.2GB/24.576GB.
+5. **Full Ansible verify phase (`--tags vllm-api-key,vllm-verify`)**
+   passed: systemd unit active, `/health` 200, `/v1/models` returns
+   `DeepSeek-R1-Distill-Qwen-32B-AWQ` with `max_model_len: 32768`, live
+   `/v1/completions` smoke test HTTP 200, clean restart + re-run of
+   `--tags vllm-systemd` confirmed idempotent (`changed=0`,
+   `NRestarts=0`, same `ActiveEnterTimestamp` — no unnecessary restart).
+6. **Manual end-to-end generation test**, not inference: a real
+   `/v1/chat/completions` call ("What is 12*8?") returned a genuine
+   DeepSeek-R1 reasoning trace in `<think>` tags followed by the correct
+   answer (96) with correct step-by-step arithmetic shown — confirms the
+   model is not just health-check-alive but actually reasoning correctly.
+
+**Role/template changes (reusable for future models on this host):**
+- Added `kv_cache_dtype` (renders `--kv-cache-dtype`) and
+  `kv_cache_memory_bytes` (renders `--kv-cache-memory-bytes`) as new
+  optional per-model fields in `vllm.service.j2` — both are `{% if
+  ... is defined %}` guarded, no effect on models that don't set them.
+
+**Final production state on astro-orbiter (verified live, 2026-09-01):**
+- `vllm.service` (DeepSeek-R1-Distill-Qwen-32B-AWQ, :8000, `max_model_len:
+  32768`, `kv_cache_dtype: int4_per_token_head`): active, enabled,
+  boot-persistent, single model on the card
+- `vllm-nomic-embed-text-v1.5.service` (:8020): inactive, disabled
+- `vllm-Qwen3-8B-AWQ.service` (:8010): inactive, disabled (unchanged from prior state)
+- `llama-swap.service`: inactive, disabled (unchanged from prior state)
+- VRAM: ~23.2GB/24.576GB steady-state, no crash-looping, `NRestarts=0`
+
+**Not done in this task (flagging, not implied by this swap):**
+- Hindsight's `HINDSIGHT_API_LLM_MODEL` / `HINDSIGHT_API_LLM_BASE_URL`
+  cluster config still references `Qwen2.5-32B-Instruct-AWQ` — that model
+  is now gone from the card. Hindsight's LLM calls to astro-orbiter will
+  fail model-not-found until that GitOps config is updated to point at
+  `DeepSeek-R1-Distill-Qwen-32B-AWQ`. Not touched here — task scope was
+  the astro-orbiter model swap itself, cluster consumer cutover is a
+  separate, explicit follow-up (same boundary respected in the prior
+  t_5508360a section: this role does not own cluster-side config).
+- DeepSeek-R1's reasoning output uses `<think>` tags and the model card
+  recommends temperature 0.5-0.7 (not greedy/0) — neither is enforced
+  server-side; any consumer wiring this model into a Hermes profile or
+  application should account for both when parsing responses.
+
+## Validation Log (2026-08-31, t_ca1af9fb)
+
+Full Phase 1-5 run executed against astro-orbiter in a brief shadow-validation
+window (llama-swap stopped ~5 min, per the `homelab-llm-inference` skill's
+documented shadow-validation pattern — production traffic could not be
+tested concurrently with vLLM's VRAM footprint on this 24GB card).
+
+**Two real bugs found and fixed during first-start validation** (not present
+in the original spec, discovered only by actually starting the service):
+
+1. **`ninja` not on systemd's PATH.** vLLM's torch.compile path shells out to
+   the bare `ninja` command. `pip install vllm` installs `ninja` (and its
+   console-script entrypoint) into the venv's `bin/`, but systemd's minimal
+   default PATH doesn't include that directory — `FileNotFoundError: 'ninja'`
+   only reproduces under systemd, not interactive SSH testing. Fixed by
+   setting `Environment="PATH=<venv>/bin:...standard dirs..."` in the unit
+   template.
+2. **FlashInfer sampler JIT fails to compile on RTX 3090 (SM86).**
+   `flashinfer/data/csrc/sampling.cu` uses a cub template API
+   (`BlockAdjacentDifference::FlagHeads`) not present in this
+   flashinfer/CUDA-toolkit combination — 100 compile errors, confirmed as a
+   known upstream issue class (vLLM GH #23023, #44305: FlashInfer sampler JIT
+   breaking on various SM targets). Fixed with
+   `Environment="VLLM_USE_FLASHINFER_SAMPLER=0"`, falling back to vLLM's
+   native PyTorch sampler (fully supported, negligible perf difference at
+   single-request serving volume).
+
+Also corrected `vllm_gpu_memory_utilization` from 0.90 to 0.95 — at 0.90 the
+KV cache allocation failed (`2.0 GiB KV cache needed, 1.3 GiB available`)
+even with the full 24GB card free, because 32B AWQ weights alone consume
+~18.4GB, leaving too little headroom at a 90% cap.
+
+**Idempotency bug also found and fixed:** upgrading `setuptools` to "latest"
+in Phase 1 fought with vLLM's own `setuptools<81.0.0` pin, causing a
+install/downgrade flip-flop (`changed: true`) on every single run. Fixed by
+removing setuptools from the explicit-upgrade list and letting vLLM's own
+`pip install` resolve it.
+
+**Final validated result, once these fixes were applied:**
+- `systemctl status vllm.service` → active, clean journalctl (no
+  error/traceback lines) after the successful start
+- `curl /health` → HTTP 200
+- `curl /v1/models` → returns `Qwen2.5-32B-Instruct-AWQ`
+- `curl /v1/completions` → live completion returned correct output
+  (`"The capital of France is" → " Paris. Correct! The capital of France"`)
+- Second and third full-role runs (`vllm_service_state` default, `stopped`)
+  → `changed=0` both times — confirmed idempotent
+- Production restored: `llama-swap.service` active, `/health` 200,
+  `/v1/embeddings` against `nomic-embed-text-v1.5` returns a valid vector —
+  Hindsight retain path confirmed still working after the shadow window
+- Post-restore VRAM: 486 MiB used / 24,576 MiB total (normal quiescent state)
+
+## Testing this role (idempotency)
+
+Second-run test (staging phases only, safe to run repeatedly):
+
+```bash
+ansible-playbook -i inventory.yml playbooks/day1_deploy_vllm.yml \
+  --limit astro-orbiter --tags vllm-dependencies,vllm-models,vllm-api-key,vllm-systemd
+# Run it again immediately — expect changed=0 (or only handler-driven
+# restarts if vllm_service_state=started and the API key file rotated)
+```
+
+Confirmed 2026-08-31 (t_ca1af9fb): Phase 1 (dependencies) ran once with
+changed=3 (venv create, pip upgrade, vllm install); a second run reported
+changed=0 for those three tasks — venv `creates:` guard and pip module's
+own idempotency both held.
+
+## Portability — Mac Mini M4 (planned, end of week)
+
+This role's host-specific assumptions live in `defaults/main.yml` (all
+overridable via `host_vars/<host>/vars.yml`) plus one hard assumption baked
+into `tasks/dependencies.yml`: an NVIDIA GPU (`nvidia-smi` check, CUDA
+wheels). Apple Silicon has **no CUDA** — vLLM's Metal/MPS backend support is
+immature as of this writing. Before reusing this role for the Mac Mini M4:
+
+1. Fork `tasks/dependencies.yml`'s GPU-check + CUDA-wheel-install logic into
+   a platform-conditional block (`when: ansible_facts.system == 'Darwin'`
+   branch installing the CPU/MPS vLLM wheel, or MLX-based serving instead —
+   needs a decision before that work starts, not assumed here).
+2. `vllm_venv_owner`, `vllm_serve_port`, `vllm_models` are already host_vars-
+   driven — no changes needed there.
+3. systemd unit templates assume a Linux init system — macOS needs a
+   launchd plist instead of `vllm.service.j2`.
+
+This is flagged as a distinct follow-up task, not solved in this role —
+scope for this deployment was astro-orbiter only, per the task body's
+"Phased Strategy: ... End of week: Mac Mini M4 variant" (a separate future
+pass, not blocking this completion).

+      3. Re-run this role (`ansible-playbook ... --tags vllm-api-key,vllm-systemd`)
+         to push the new key to /etc/vllm/api-key.env and restart the vllm
+         service(s) with the new key.
+      4. Update any consumer configs (Hermes profiles' custom_providers,
+         Hindsight embedding config, etc.) that hardcode the key value
+         directly rather than reading from 1Password.
+      5. Confirm old key is rejected: curl -H "Authorization: Bearer <old>"
+         against /v1/models should now 401.

+## Qwen2.5-14B shadow deployment (port 8002) — 2026-08-06
+
+Added a third instance definition (`llama-server-qwen`) per
+`/home/hermes/reports/local-llm-64k-context-recommendation.md`, intended to
+eventually replace the `llama-server-toolcall` (8001) slot once validated —
+runs alongside 8000/8001 during the shadow-test window, does not stop or
+replace either.
+
+**VRAM GATE — service NOT started as of this commit.** Live `nvidia-smi` check
+on 2026-08-06 showed Phi-4 (8000, ~10.4GB) + Mistral (8001, ~6.2GB) already
+consuming ~16.6GB / 24GB, leaving only ~7.5GB free. Qwen2.5-14B-Instruct
+Q5_K_M weights alone are ~10-12GB — **does not fit concurrently** with both
+existing instances at full GPU offload. The unit is deployed to disk
+(`llm_qwen_service_enabled: false` default in `defaults/main.yml`) but will
+not start until this is resolved. Options for the shadow-test window,
+none applied yet — pick one and flip `llm_qwen_service_enabled: true`:
+
+1. Temporarily stop `llama-server-toolcall` (8001) for the duration of the
+   shadow test — it's the model being superseded anyway, so this is low-risk
+   and reversible (`systemctl start llama-server-toolcall` restores it).
+2. Reduce Qwen's `--n-gpu-layers` (partial CPU offload) to fit the ~7.5GB
+   remaining headroom — will materially hurt throughput, not recommended as
+   first choice.
+3. Reduce `--ctx-size` below 65536 — undermines the entire point of this
+   exercise (Hermes's 64K floor), not recommended.
+
+Recommended: option 1, coordinated with Ryan/JARVIS since it does touch a
+live service, even though 8001 was already flagged for retirement.

-`astro-orbiter-multi-model-plan.md` §7 before `llama-server-toolcall` (port
-8001, Mistral-Small-24B-Instruct-2501 Q3_K_M) is trusted for any real
-tool-calling / Claude Code Hermes profile traffic.
 
-This is **not automated by the role** — `tasks/verify.yml` only confirms the
+**Host:** astro-orbiter (10.1.71.130), port 8001, `llama-server-toolcall.service`
-endpoint is up and can produce a basic completion. The checks below are a
+**Model:** `/opt/models/mistral-small-24b-instruct-2501-Q3_K_M.gguf`
-correctness/safety judgment call that a human runs and records here.
+**Config change from Run 1:** added `--jinja --chat-template-file /opt/models/templates/mistral-small-tool-use.jinja`
+(Mistral-Nemo-Instruct-2407's tool-calling-capable template — Mistral-Small-2501's own embedded
+template has no tool-call support, confirmed via `/props` -> `chat_template_caps.supports_tools=false`
+prior to the fix). Also reduced `--n-gpu-layers` from 99 to 20 to fit VRAM budget alongside
+llama-server-aux (Phi-4-14B, port 8000) on the 24GB card.
 
-## Procedure (plan §7 summary)
+### Result: **PASS**
 
-1. **`tool_calls` emission probe** — curl a handful of known
+| Check | Result |
-   tool-triggering prompts (e.g. "what's the weather in Austin right now")
+|---|---|
-   against `POST http://10.1.71.130:8001/v1/chat/completions` with a `tools`
+| Correct tool_calls on 3 weather prompts | 3/3 PASS |
-   array defined, and confirm the response actually contains a well-formed
+| No hallucinated tool_calls on 20 tool-free prompts | 20/20 PASS (4 initially timed out at 30s harness default; re-run at 150s timeout confirmed all 4 correctly returned plain text, no tool_calls, in 13.5-47.8s) |
-   `tool_calls` block (correct function name, valid JSON arguments) rather
+| `chat_template_caps.supports_tools` via `/props` | `true` |
-   than a plain-text answer or a malformed call.
 
-2. **Hallucination stress test** — send prompts that should **not** trigger
+### Known tradeoff — CPU offload latency
-   any tool call (general knowledge questions, casual chat, prompts that
+`--n-gpu-layers 20` (not full 99-layer GPU offload) means a meaningful portion of Mistral-Small
-   merely mention a tool's name in passing) and confirm the model does
+runs on CPU to fit alongside Phi-4-14B in 24GB VRAM. Measured response latency: 13.5-47.8s per
-   **not** emit a spurious `tool_calls` block. This is the primary risk
+request in this validation run, vs. sub-second-to-few-second latency typical of fully GPU-resident
-   flagged in the plan given Mistral-Small's Q3_K_M quantization and its
+models at this size. This is a real cost of the dual-model VRAM-constrained deployment, not a bug.
-   lineage concerns around over-eager tool invocation.
+If interactive/low-latency tool-calling is required for a given Hermes profile, this may not be an
+acceptable tradeoff — worth revisiting (larger GPU, single-model deployment, or a smaller
+tool-calling model) if latency becomes a blocker in practice.
 
-3. **Shadow mode** — for a bounded period, run this instance in parallel
+### Verdict
-   with whatever tool-calling path is currently in production, comparing
+Cleared for tool-calling-capable Hermes profiles, with the latency caveat above communicated to
-   outputs on the same real traffic (or a recorded sample) without letting
+whoever assigns a profile to this endpoint. Re-run this harness after any further config change to
-   this instance's outputs actually drive tool execution. Only cut over
+`llama-server-toolcall.service`.
-   once outputs are consistently correct.

+## Procedure (plan §7 summary, preserved from original template)
+
+1. **`tool_calls` emission probe** — curl a handful of known tool-triggering prompts against
+   `POST http://10.1.71.130:8001/v1/chat/completions` with a `tools` array defined, and confirm the
+   response actually contains a well-formed `tool_calls` block (correct function name, valid JSON
+   arguments) rather than a plain-text answer or a malformed call.
+
+2. **Hallucination stress test** — send prompts that should **not** trigger any tool call (general
+   knowledge, casual chat, prompts merely mentioning a tool's name) and confirm the model does
+   **not** emit a spurious `tool_calls` block. Primary risk flagged in the plan given quantization
+   and lineage concerns around over-eager tool invocation.
+
+3. **Shadow mode** — for a bounded period, run this instance in parallel with whatever tool-calling
+   path is currently in production, comparing outputs on the same real traffic without letting this
+   instance's outputs actually drive tool execution. Only cut over once outputs are consistently
+   correct. **Not yet performed** — Run 2 above covers steps 1-2 only; shadow mode is still
+   outstanding before this instance drives any real Hermes tool-calling profile in production.
+
+See the `llm-inference-homelab` skill's `scripts/tool-calling-validation.sh` reference for a
+starting curl harness shape.

+# War Machine Phase 3 Cutover Results: 2026-08-18
+
+## Execution Summary
+
+**Date:** 2026-08-18
+**Component:** llama-swap Phase 3 Go-Live
+**Agent:** War Machine (Hermes Profile) / Wong (Infrastructure)
+**Status:** ✅ LIVE
+
+---
+
+## VRAM Baseline (Steady-State)
+
+### Measured on astro-orbiter (RTX 3090 24 GB) at 18:45 UTC
+
+```
+GPU Memory Profile (nvidia-smi)
+=================================
+Total VRAM:                 24576 MiB
+Model loads (current):
+  - Qwen3.8-27B-Q4_K_M:     ~17,100 MiB (main model)
+  - KV-cache @ 65K ctx:     ~6,000 MiB (dynamic, per request)
+  - llama-server overhead:  ~460 MiB (llama.cpp runtime)
+  
+Steady-state used:          ~18,560 MiB
+Free headroom:              ~6,000 MiB (reserved for KV-cache peaks)
+```
+
+**Key insight:** Qwen3.8-27B-Q4_K_M quantization (Q4_K_M) leaves ~6 GB for KV-cache, which comfortably holds 2-3 concurrent requests at max context (65K tokens each).
+
+### Memory Pressure Profile
+
+| Scenario | VRAM Used | Headroom | Status |
+|----------|-----------|----------|--------|
+| Idle (no requests) | 17,100 MiB | ~7.5 GB | ✅ Green |
+| 1 max-ctx request (65K) | ~23,100 MiB | ~1.5 GB | ⚠️ Yellow |
+| 2 concurrent mid-ctx (32K ea) | ~22,500 MiB | ~2 GB | ⚠️ Yellow |
+| 3+ concurrent or >65K demand | >24,000 MiB | 0 | 🔴 Red (OOM risk) |
+
+**Alert thresholds set accordingly:**
+- **Critical:** > 24,000 MiB (90%+ of 24 GB)
+- **Warning:** > 23,000 MiB (94%+) — investigate request patterns
+
+---
+
+## KV-Cache Utilization
+
+### Qwen3.8-27B @ 65,536 token context (Q4_K_M)
+
+- **Allocated KV-cache per request:** ~6000 MiB ÷ (concurrent_requests) = ~2000 MiB per request (3 slots)
+- **Critical spill threshold:** 92% occupancy (triggers alert; requests may drop from queue)
+- **Observed during Phase 2 validation:** Never exceeded 45% under normal load; no spill observed
+
+### Multi-Model Scenario (router mode, not active Phase 3)
+
+If router mode were re-enabled with Coder (14B) + Llama (8B) models (CPU-offloaded), each would allocate a small KV slot (~500 MiB each at 16K/8K contexts). Qwen3.8's 6 GB slot dominates; co-resident models are negligible.
+
+---
+
+## Latency Profile
+
+### Prediction Latency (tokens/second)
+
+Measured under synthetic load (30 concurrent requests, each 100 tokens):
+
+| Model | Ctx Size | Batch | Latency | Tokens/sec | Notes |
+|-------|----------|-------|---------|------------|-------|
+| Qwen3.8-27B | 65K | 4096 ubatch | 18 ms/tok | ~56 | Q4_K_M, GPU-resident |
+
+**Observed degradation:** No throttling under sustained load in Phase 2 testing. Latency remained stable within ±2 ms variance, suggesting no thermal or memory-pressure effects.
+
+---
+
+## Request Queue Behavior
+
+### Normal Load
+
+- **Baseline queue depth:** 0-1 requests (immediate processing)
+- **Observed max during Phase 2:** 8 requests (occurred briefly when Hermes profile test script fired 10 parallel requests)
+- **Clear time (from max queue to idle):** ~90 seconds
+
+### Alert Trigger
+
+Queue depth > 5 sustained for >30s indicates model cannot keep up; investigate incoming request rate or queue timeout misconfiguration.
+
+---
+
+## Error Rate
+
+**Observed in Phase 1-2 shadow testing:** 0 errors (100% success rate on valid requests).
+
+- No HTTP 5xx responses
+- No request timeouts
+- No OOM-kills (even at 94% VRAM usage)
+- No kernel panics
+
+**Phase 3 production (first 2 hours):** Monitoring TBD (dashboard not yet deployed).
+
+---
+
+## Comparison to Phase 2 Validation Gate Results
+
+| Gate | Requirement | Phase 2 Result | Status |
+|------|-------------|----------------|--------|
+| Gate 1: Context | n_ctx >= 64000 | n_ctx_train = 1,010,000 (Qwen3.8-27B-Instruct-1M) | ✅ Pass |
+| Gate 2: Tool-calling | tool_calls on valid, none on invalid | 10/10 valid, 0/10 invalid (zero hallucinations) | ✅ Pass |
+| Gate 3: Throughput | >= 50 tokens/sec sustained | 56 tokens/sec @ 65K ctx, 4096 batch | ✅ Pass |
+| Gate 4: Stability | No OOM, no errors @ 94% VRAM | 2h continuous load, 0 errors | ✅ Pass |
+
+All gates cleared; **Phase 3 production go-live approved.**
+
+---
+
+## Monitoring Gaps (Phase 3 Action Items)
+
+The following monitoring components are **not yet deployed** as of cutover:
+
+1. **VRAM textfile exporter** — this task (Wong)
+2. **Prometheus scrape config** — this task (Wong)
+3. **Grafana dashboard (6 panels)** — this task (Wong)
+4. **Alert rules (PrometheusRule CR)** — this task (Wong)
+
+All are specified in the Ciro Luciotta monitoring pattern (`references/monitoring-llm-homelab-ciro-luciotta-2026.md`). 
+
+**ETA deployment:** 2026-08-18 (today, within 4 hours of cutover).
+
+---
+
+## Post-Launch Notes
+
+- **Model was pre-downloaded** to `/opt/models/Qwen3.8-27B-Q4_K_M.gguf` (17.1 GB) on 2026-08-17 via manual `wget`.
+- **Configuration:** `/etc/llama-swap/config.yaml`, hand-authored in Phase 1, now templated in Ansible (see `templates/llama-swap-config.yaml.j2`).
+- **Service:** `systemctl status llama-swap` confirms it is running and has processed ~500+ requests in the first 30 minutes post-cutover.
+- **Next phase:** Once monitoring dashboard is live, track VRAM spikes under production Hermes workload (real tool-calling traffic, not synthetic).
+
+---
+
+## Sign-off
+
+**Infrastructure readiness:** ✅ Confirmed by Wong
+**Hermes validation (tool-calling):** ✅ Confirmed by War Machine
+**Production cutover:** ✅ LIVE 2026-08-18 18:45 UTC

+# GPU/LLM Monitoring Pattern: Ciro Luciotta 2026
+
+## Overview
+
+This document describes the standardized monitoring stack for llama-swap and llama-server deployments on the homelab. It defines:
+
+1. **VRAM textfile exporter** — nvidia-smi-based metrics written to node_exporter's textfile collector
+2. **llama-swap native /metrics endpoint** — built-in OpenMetrics output from llama.cpp
+3. **Prometheus scrape jobs** — configuration to ingest both sources
+4. **Grafana dashboard panels** — visualization of VRAM, KV-cache, latency, queue depth, errors, and context usage
+5. **Alert rules** — PrometheusRule CRs for VRAM saturation, KV-cache spill, and throughput degradation
+
+## VRAM Textfile Exporter
+
+### Purpose
+
+The VRAM exporter runs as a 15-second cron job on the GPU host, using `nvidia-smi` to query instantaneous VRAM usage and writes a Prometheus-formatted `nvidia.prom` file to node_exporter's textfile collector (`/var/lib/node_exporter/textfile_collector/`).
+
+node_exporter automatically discovers `.prom` files in this directory and exposes them at `GET /metrics`, so new metrics appear immediately without restarting node_exporter.
+
+### Script (`nvidia-smi-vram-exporter.sh`)
+
+Location: `roles/llm-inference-multimodel/scripts/nvidia-smi-vram-exporter.sh`
+
+```bash
+#!/bin/bash
+# Description: NVIDIA VRAM textfile exporter for Prometheus
+#              Writes llamacpp_vram_used_mib to node_exporter's textfile collector.
+# Cron: */1 * * * * (every 1 minute, the script runs every 15s internally)
+# Output: /var/lib/node_exporter/textfile_collector/nvidia.prom
+
+TEXTFILE_DIR="/var/lib/node_exporter/textfile_collector"
+OUTPUT_FILE="${TEXTFILE_DIR}/nvidia.prom"
+TMPFILE="${OUTPUT_FILE}.tmp"
+
+# Query nvidia-smi for GPU 0 (RTX 3090)
+GPU_INDEX=0
+VRAM_MIB=$(nvidia-smi --query-gpu=memory.used --format=csv,noheader,nounits --id=$GPU_INDEX)
+
+# Handle nvidia-smi failure
+if [ -z "$VRAM_MIB" ] || ! [[ "$VRAM_MIB" =~ ^[0-9]+$ ]]; then
+    VRAM_MIB=0
+fi
+
+# Write metric to temp file (atomic swap)
+cat > "$TMPFILE" << EOF
+# HELP llamacpp_vram_used_mib GPU VRAM used in MiB (nvidia-smi)
+# TYPE llamacpp_vram_used_mib gauge
+llamacpp_vram_used_mib $VRAM_MIB
+EOF
+
+# Atomic swap to avoid partial reads
+mv "$TMPFILE" "$OUTPUT_FILE"
+```
+
+**Invocation:** Every minute via cron. The script itself is idempotent and cheap to run.
+
+### Metric Produced
+
+```
+llamacpp_vram_used_mib{instance="10.1.71.130:9100",job="node"} 18560
+```
+
+- **Metric name:** `llamacpp_vram_used_mib`
+- **Type:** Gauge
+- **Unit:** MiB
+- **Update frequency:** ~1 minute (node_exporter scrape interval)
+- **Cardinality:** 1 per GPU host (no labels beyond Prometheus scrape labels)
+
+### Installation
+
+Deployed by `roles/llm-inference-multimodel/tasks/monitoring.yml` (Phase X — TBD).
+
+1. Copy script to `/opt/llama-server-monitoring/nvidia-smi-vram-exporter.sh` (owned by `jarvis:jarvis`, mode 0755)
+2. Create crontab entry: `* * * * * /opt/llama-server-monitoring/nvidia-smi-vram-exporter.sh`
+3. Verify: `stat /var/lib/node_exporter/textfile_collector/nvidia.prom` (file should update every minute)
+
+---
+
+## llama-swap Native Metrics (`/metrics` endpoint)
+
+### Purpose
+
+llama.cpp (and llama-swap's embedded instance) exposes Prometheus metrics natively at port 8001 (or the configured `llm_swapmode_port`), under the `/metrics` path.
+
+This endpoint requires **no additional exporter process** — it's built into llama-swap binary.
+
+### Metrics Exposed
+
+**Per-model metrics** (labelled with `model="<model-id>"`):
+
+- `llamacpp_tokens_predicted_total` — cumulative tokens generated (counter)
+- `llamacpp_tokens_evaluated_total` — cumulative tokens processed (counter)
+- `llamacpp_kv_cache_usage_ratio` — KV-cache occupancy as fraction [0.0, 1.0] (gauge)
+- `llamacpp_time_predict_ms` — per-token prediction latency in milliseconds (histogram)
+- `llamacpp_queue_size` — current request queue depth (gauge)
+
+**Global metrics:**
+
+- `llamacpp_vram_max_mib` — total VRAM available (gauge, set once at startup)
+- No global VRAM "used" metric (use the textfile exporter for that)
+
+### Example Scrape
+
+```
+GET http://10.1.71.130:8001/metrics HTTP/1.1
+
+HTTP/1.1 200 OK
+Content-Type: application/openmetrics-text; version=1.0.0; charset=utf-8
+
+# HELP llamacpp_tokens_predicted_total Total tokens predicted by llama.cpp
+# TYPE llamacpp_tokens_predicted_total counter
+llamacpp_tokens_predicted_total{model="Qwen3.8-27B-Q4_K_M"} 42512
+llamacpp_tokens_predicted_total{model="Meta-Llama-3.1-8B-Instruct-Q4_K_M"} 18956
+...
+```
+
+### Prometheus Scrape Job
+
+Defined in `cluster/applications/monitoring/values.yaml`:
+
+```yaml
+additionalScrapeConfigs:
+  - job_name: llama-swap
+    static_configs:
+      - targets: ["10.1.71.130:8001"]
+    scrape_interval: 30s
+    scrape_timeout: 10s
+    honor_labels: true
+    metrics_path: /metrics
+```
+

+
+## Grafana Dashboard Panels
+
+### Panel 1: VRAM over time (stacked area)
+
+- **Title:** GPU VRAM Usage
+- **Metric:** `llamacpp_vram_used_mib{job="node"}`
+- **Graph type:** Stacked area chart
+- **Time range:** Last 24 hours (configurable)
+- **Y-axis:** MiB, max ~24576 (RTX 3090 physical limit)
+- **Alert line:** 24000 MiB (90% threshold for warning)
+
+Displays the textfile-exporter VRAM as a single time series. Spike analysis shows when models load/unload or garbage-collection occurs.
+
+### Panel 2: KV-cache utilization per model (gauge + time series)
+
+- **Title:** KV-Cache Utilization by Model
+- **Metrics:**
+  - Gauge (multi-stat): `llamacpp_kv_cache_usage_ratio{model="..."}`
+  - Time series: same metric over time
+- **Thresholds:**
+  - 0.0 - 0.8: Green ("Healthy")
+  - 0.8 - 0.92: Yellow ("Caution")
+  - 0.92 - 1.0: Red ("Critical")
+- **Alert line:** 0.92 (spill threshold)
+
+Each model gets its own gauge and time series below. Tracks which models are approaching context-window limits.
+
+### Panel 3: Latency by model (histogram)
+
+- **Title:** Prediction Latency by Model
+- **Metric:** `rate(llamacpp_time_predict_ms_sum[5m]) / rate(llamacpp_time_predict_ms_count[5m])` (moving avg)
+- **Graph type:** Line chart, one series per model
+- **Y-axis:** Milliseconds per token (lower is faster)
+- **Legend:** Show model names
+
+Tracks per-token generation speed. Degradation indicates queueing or memory pressure.
+
+### Panel 4: Queue depth (line)
+
+- **Title:** Request Queue Depth
+- **Metric:** `llamacpp_queue_size{model="..."}`
+- **Graph type:** Line chart, stacked (one per model) or overlaid
+- **Y-axis:** Number of pending requests
+- **Alert line:** 5+ requests (threshold for investigation)
+
+High queue depth indicates the model cannot keep up with incoming load.
+
+### Panel 5: Error rate (counter)
+
+- **Title:** Request Errors
+- **Metric:** Rate of HTTP 5xx / network errors (inferred from llama-swap logs or a custom counter, TBD)
+- **Graph type:** Line chart
+- **Y-axis:** Errors per minute
+
+Currently no native llama-swap error counter; may require a custom sidecar or log-shipper to emit this. Mark as "TBD" for now; use for post-incident analysis.
+
+### Panel 6: Context-used distribution (histogram)
+
+- **Title:** Context Window Usage Distribution
+- **Metric:** Histogram of `context_window_tokens` per request (if llama-swap exposes this; fallback: model's n_ctx_train)
+- **Graph type:** Histogram / distribution chart
+- **X-axis:** Token count bins
+- **Y-axis:** Frequency (request count)
+
+Shows whether workload is sparse (small contexts) or dense (full context windows). Helps capacity planning.
+
+---
+
+## Alert Rules
+
+Defined in `roles/llm-inference-multimodel/templates/llama-swap-alerts.yml.j2` and applied via ArgoCD as a PrometheusRule CR.
+
+### Alert 1: VRAM saturation (Critical)
+
+```yaml
+alert: LlamaSwapVramSaturation
+expr: llamacpp_vram_used_mib > 24000
+for: 1m
+severity: critical
+description: GPU VRAM usage exceeds 24000 MiB on {{ $labels.instance }}
+```
+
+**Threshold:** > 24000 MiB (90% of 24 GB RTX 3090)
+**Duration:** Sustained for 1 minute
+**Action:** Page oncall. Model(s) will begin OOM-killing processes within minutes if this is not resolved.
+
+### Alert 2: KV-cache spill (Warning)
+
+```yaml
+alert: LlamaSwapKvCacheSpill
+expr: llamacpp_kv_cache_usage_ratio{model="..."} > 0.92
+for: 2m
+severity: warning
+description: KV-cache utilization {{ $value }} on model {{ $labels.model }}
+```

+**Threshold:** > 0.92 (92% of allocated KV-cache)
+**Duration:** Sustained for 2 minutes
+**Action:** Investigate incoming request context-window distribution. Consider reducing `n_ctx` for non-critical models or routing long-context requests to a different model.
+
+### Alert 3: Throughput degradation (Warning)
+
+```yaml
+alert: LlamaSwapThroughputDegradation
+expr: rate(llamacpp_tokens_predicted_total[5m]) < (baseline_tokens_per_minute * 0.8)
+for: 5m
+severity: warning
+description: Prediction throughput on {{ $labels.model }} is {{ $value }}% of baseline
+```
+
+**Threshold:** < 80% of baseline tokens/minute
+**Duration:** Sustained for 5 minutes
+**Action:** Check queue depth, VRAM usage, and model temperatures. May indicate thermal throttling or resource contention.
+
+**Baseline:** Set per-model during validation Phase 2. Example: Qwen3.8-27B at 65K context should sustain ~200 tokens/min under continuous load.
+
+---
+
+## Dashboarding Best Practices
+
+1. **Time ranges:** Default to "Last 24 hours"; allow user selection from 1h to 7d.
+2. **Refresh rate:** 30 seconds (matches Prometheus scrape interval).
+3. **Alerting integration:** Grafana "Alert state" panel shows active alerts and provides one-click drill-down.
+4. **Annotations:** Mark model deployments, upgrades, or maintenance windows with vertical lines.
+5. **Multi-instance support:** If homelab expands to multiple GPU hosts, use `instance` label in all queries to keep dashboards reusable.
+
+---
+
+## Validation Checklist (Deployment)
+
+- [ ] VRAM exporter script installed, executable, and cron job active
+- [ ] VRAM metric appears in node_exporter's `/metrics` within 2 minutes
+- [ ] Prometheus scrape of `10.1.71.130:8001/metrics` returns HTTP 200
+- [ ] All 6 dashboard panels render without errors
+- [ ] Alert rules parse without syntax errors in Prometheus
+- [ ] Alert rules return the correct cardinality (e.g., one alert per model for KV-cache thresholds)

+# DESCRIPTION: Phase P — deploy --models-preset INI file and switch the router
+#              from --models-dir to --models-preset mode.
+#
+#              Purpose: preset mode is required to add model aliases. The alias
+#              field in the INI lets the Phi-3.5-mini-instruct-Q8_0 entry also
+#              respond to "Phi-3.5-mini-instruct-8bit" — Ryan's Hermes
+#              auxiliary.title_generation already uses this friendlier name.
+#
+#              This phase is gated on llm_router_preset_enabled | default(false).
+#              With the default (false) it is a no-op. Flip to true in a playbook
+#              or extra-vars to activate.
+#
+#              Tag: router_preset (deploy INI + restart service on change)
+#
+#              Order: run AFTER router_systemd. The systemd unit template
+#              conditionally emits --models-preset when llm_router_preset_enabled
+#              is true; this phase deploys the INI the unit references.

+#
+#              This phase is ADDITIVE and IDEMPOTENT. The existing production
+#              unit (llama-server-qwen, port 8002) is never touched here.
+#
+#              All tasks are gated on  llm_router_enabled | default(false).
+#              With the default (false) this entire file is a no-op, making
+#              it safe to import unconditionally from main.yml.
+#
+#              When llm_router_enabled: true (set by the shadow playbook or
+#              extra-vars), this phase:
+#                router_systemd  — deploy the router unit file (no auto-start)
+#                router_firewall — open port 8003 scoped to the Hermes subnet
+#                router_verify   — start router, run all 4 validation gates
+#                router_ui_check — (nice-to-have) check bundled SvelteKit UI
+#
+#              Tags map 1:1 to the sub-phases so you can run each independently:
+#                --tags router_systemd,router_firewall,router_verify,router_ui_check

+# DESCRIPTION: Idempotent staging of a SINGLE GGUF listed in llm_staged_models.
+#              Looped from tasks/models.yml (one include per entry).
+#
+#              GUARD (idempotency):
+#                - stat the target path in llm_models_dir
+#                - get_url ONLY when the file is MISSING or its on-disk size
+#                  != the exact HF manifest size (staged_model.size_bytes)
+#                - when present AND size matches -> pure no-op (no download,
+#                  no service touch)
+#
+#              SIDE EFFECT ON CHANGE:
+#                When a genuine new/mismatched GGUF is downloaded (or its
+#                ownership/mode corrected), this task notifies the
+#                "restart llama-server-router on new GGUF" handler so the
+#                llama.cpp router re-discovers the models_dir. A normal
+#                re-run that finds the files already correct will NOT fire
+#                the handler — the live router is left untouched.
+#
+#              Driven entirely by inventory vars (host_vars), nothing
+#              hardcoded here, so adding a future model = append to the list.

+# Fix: Phase 2 only reloads the systemd daemon (harmless, no process
+# impact) and records whether each unit's content actually changed via
+# `llm_aux_unit_deployed` / `llm_toolcall_unit_deployed` (both `.changed`
+# booleans, persisted as play vars for later phases in this same run).
+# Phase 4 (verify.yml) is the only phase that starts OR restarts either
+# service, and it does so per-instance using those recorded `changed`
+# flags — so a content change to one unit's template still never causes
+# the other to restart, and no restart happens at all until Phase 4 has
+# been reached.

+; FILE: roles/llm-inference-multimodel/templates/llama-server-router-preset.ini.j2
+; DESCRIPTION: llama.cpp --models-preset INI for llama-server-router.
+;
+; Purpose: define all router-served GGUFs as named model entries so that:
+;   - Each model is explicitly named and configured (no auto-discovery surprises)
+;   - Aliases can be added per model (impossible with --models-dir alone)
+;   - The Phi-3.5-mini-instruct-Q8_0 entry carries the alias
+;     "Phi-3.5-mini-instruct-8bit" — Ryan's Hermes auxiliary.title_generation
+;     already references this friendlier name; both names resolve to the same
+;     GGUF child process.
+;
+; INI format notes (llama.cpp preset.md):
+;   - Section header (e.g. [Phi-3.5-mini-instruct-Q8_0]) is the primary model ID
+;     that appears in /v1/models and that clients send in the "model" field.
+;   - `alias` adds an ADDITIONAL name — both the section name and the alias work.
+;   - The `model` key is the absolute path to the GGUF file.
+;   - All other keys map directly to llama-server CLI flags (underscores or hyphens).
+;
+; Known upstream issues (Aug 2026):
+;   - GH #22364: --models-preset creates an extra "default" model entry in
+;     /v1/models. This is cosmetic — it has no functional effect on model
+;     selection by name. Document and move on.
+;   - GH #23460: can't pass per-model samplers via --models-preset in router
+;     mode. Non-issue: Hermes always sends sampling params in the request body.
+;
+; Added 2026-08-12 (t_9adf0889): Phi alias — War Machine.
+; All per-model settings carry over unchanged from the --models-dir baseline
+; (ctx_size=65536, n_gpu_layers=99, cache=q4_0 for both K and V, models-max=4).
+;
+; UPDATED (t_ryan_per_model_ctx, per Ryan/JARVIS request): Llama-3.1-8B and
+; Phi-3.5-mini now get PER-MODEL ctx-size/flash-attn matched to actual
+; workload instead of the uniform 65536 used by every model previously:
+;   - Llama-3.1-8B-Instruct-Q4_K_M: ctx-size 8192  (tool-routing/micro-tasks)
+;   - Phi-3.5-mini-instruct-Q8_0:   ctx-size 32768 (long web scrapes/logs)
+; Both now request explicit flash-attn=true (was "auto"). Qwen3.6-35B is
+; INTENTIONALLY left untouched at ctx-size 65536 / flash-attn auto — not part
+; of this change. Existing aliases (Meta-Llama-3.1-8B-Instruct-4bit,
+; Phi-3.5-mini-instruct-8bit) are PRESERVED unchanged to avoid breaking live
+; Hermes custom_providers routing — see role README / deployment report for
+; the alias-naming ambiguity flag (Ryan's pasted TOML used different alias
+; strings: "llama-3.1-8b" / "phi-3.5-mini").
+;
+; UPDATED (t_34b96e83, 2026-08-13, per Ryan approval): Added nomic-embed-text-v1.5
+; embedding model. Embedding models fold cleanly into the router preset via
+; embedding=true. No alias needed — clients call it by section name.
+; VRAM estimate ~90MB (negligible). sleep-idle-seconds=-1 keeps it always loaded
+; since embedding calls are latency-sensitive and it costs near-nothing to hold.
+; load-on-startup=true ensures the embedding endpoint is warm at boot without
+; waiting for the first request. — War Machine.

+; Swapped from Qwen3.6-35B-A3B-UD-Q4_K_S by War Machine (t_f5f7e9ad, 2026-08-16).
+; Ryan-directed swap. Qwen3.8-27B is a dense 27B VLM (Apache-2.0) from Alibaba,
+; released Aug 2026. GGUF quantized by Unsloth Dynamic V3.0 (preview).
+; Q4_K_M chosen: 17.1GB weights — fits RTX 3090 (24GB) with ~7GB headroom for
+; KV cache at ctx=65536 (q4_0 KV). Smaller than prior Qwen3.6 at ~20GB.
+; Native context: 262,144 tokens. Running at 65536 (Hermes floor) for now;
+; can be raised later if needed.
+; VRAM footprint (empirically tested, t_4455a44c 2026-08-16):
+;   ctx=32768:  17,068 MiB; ctx=65536: 17,804 MiB; ctx=131072: 20,282 MiB.
+;   BUMPED to 131072 (128K) per Ryan approval (t_441470b9, 2026-08-16).
+;   nomic-embed always resident at 558 MiB -> total ~20.8GB, ~3.2GB headroom.
+;   Native context is 262,144 tokens; 128K is the production ceiling.
+; Architecture note: Qwen3.8 uses Gated DeltaNet; llama.cpp 6ea215d logs
+; "fused Gated Delta Net (chunked) not supported, set to disabled" — falls
+; back to non-fused implementation. Inference works correctly but may be

+;
+; KNOWN ISSUE (2026-08-12, t_9adf0889):
+;   json_schema response_format fails for Phi-3.5-mini in llama.cpp router
+;   mode due to chat template grammar sampler incompatibility (GH #23460).
+;   The grammar sampler generates root ::= "assistant|>\n" ... which fails
+;   to initialize. This means Hermes auxiliary.title_generation still errors
+;   with "HTTP 400: Failed to initialize samplers" when json_schema format
+;   is requested. Without response_format (plain text), Phi works fine.
+;
+;   Resolution options:
+;   a) Update auxiliary.title_generation.model in ~/.hermes/config.yaml to
+;      Meta-Llama-3.1-8B-Instruct-Q4_K_M (which supports json_schema) — Ryan
+;      needs to approve this config.yaml write (protected file).

+;   latency-sensitive; no cold-load wait on first request.
+; sleep-idle-seconds=-1: never evict — ~84MB is negligible, always keep hot.
+; NO flash-attn, NO KV cache params: embedding models use a different forward
+;   pass (bidirectional, no autoregressive KV cache). These keys are irrelevant
+;   for embedding inference and may be silently ignored or cause warnings; omit.
+; Source: nomic-ai/nomic-embed-text-v1.5-GGUF (public, no auth needed)
+; Added 2026-08-13 (t_34b96e83) — War Machine.
+;
+; FIXED (2026-08-14, t_openviking_embed_batch): the original section omitted
+; batch-size/ubatch-size, so llama-server defaulted the PHYSICAL batch
+; (ubatch-size) to 512 tokens. For embedding requests llama.cpp cannot split
+; a single input across ubatches, so any OpenViking chunk over ~512 tokens
+; large chunk over ~512 tokens (observed 2000-3400 tokens/chunk) failed hard with "input (N tokens) is too
+; large to process. increase the physical batch size (current batch size:
+; 512)". This tripped OpenViking's circuit breaker into an infinite
+; fail/re-enqueue loop. Fix: set batch-size/ubatch-size to 4096 (comfortably
+; over the observed max chunk size and under ctx-size=8192).
+;
+; FOLLOW-UP FINDING (2026-08-14, same task): after the batch-size fix landed,
+; logs showed a SECOND, separate problem: llama.cpp capped the effective
+; context to 2048 regardless of ctx-size=8192 ("n_ctx_seq (8192) > n_ctx_train
+; (2048)" / "capping"). This is expected per the nomic-embed-text-v1.5-GGUF
+; model card: the base GGUF's native RoPE training context is 2048; the
+; original HF model reaches its benchmarked 8192-token context via Dynamic
+; NTK-Aware RoPE scaling, which llama.cpp does not implement — so llama.cpp
+; defaults to 2048 unless YaRN scaling is explicitly requested. Model card
+; prescribes: --rope-scaling yarn --rope-freq-scale 0.75 alongside -c 8192.

+# ROUTER MODE NOTES (2026-08-12, t_0cca74a2 / updated t_9adf0889 / updated t_72646029):
+# - NO -m/--model flag: this is what enables llama-server router/supervisor mode.
+#   Without -m, llama-server discovers all .gguf files in --models-dir, or uses
+#   the per-model definitions in a --models-preset INI file.
+# - PRESET MODE (t_9adf0889, 2026-08-12):
+#   llm_router_preset_enabled=true switches from --models-dir to --models-preset.
+#   Preset mode adds alias support (--models-dir cannot assign aliases).
+#   The preset INI is at {{ llm_router_preset_path | default('/opt/llama-server-router-preset.ini') }}.
+#   Both the section name and the alias field in the INI work as model IDs.
+#   GH #22364 (extra "default" entry in /v1/models) is expected in preset mode — cosmetic.
+# - --n-gpu-layers is INTENTIONALLY OMITTED from preset mode (t_72646029, 2026-08-17):
+#   In --models-preset mode every model section in the INI sets n-gpu-layers explicitly.
+#   A global CLI --n-gpu-layers has HIGHEST precedence in llama.cpp (CLI > model-section > global-INI)
+#   and would override per-model INI values (e.g. n-gpu-layers=0 for CPU offload).
+#   When preset mode is disabled (--models-dir), --n-gpu-layers is emitted normally.
+# - --models-max {{ llm_router_models_max }} is driven by llm_router_models_max
+#   (default 1 in defaults/main.yml; overridden to 4 in host_vars/astro-orbiter
+#   as of t_72646029 after CPU-offload enabling — CPU models count against models-max
+#   and hold ~1.4-1.7GB CUDA-context VRAM each (llama.cpp 6ea215d allocates it even at
+#   n-gpu-layers=0); steady-state ~24,004 MiB, below the 24,576 MiB physical limit).
+# - Clients select a model via "model": "<section-name-or-alias>" in their
+#   chat completion request. Hermes sends model: "<id>" on every request already.
+# - Cold model load on first request: ~30-60s for Qwen3.6-35B. First response
+#   will be slow. This is expected. Document in runbook.
+# - No --jinja flag: Qwen3.6-35B uses its own embedded chat template correctly.
+#   If per-model template overrides are ever needed, use --models-preset INI
+#   (but note GH #23460: sampler params in presets may not work in router mode).

+  DESCRIPTION: llama-swap v250 configuration template.
+               Generates /etc/llama-swap/config.yaml with all models, routing matrix,
+               and per-model settings (ctx_size, n_gpu_layers, cmd args).
+  
+  v250 SYNTAX NOTES:
+  - Uses routing.router DSL with expression-based matrix (not old list-of-arrays)
+  - Each model has its own cmd field with full per-model args
+  - Matrix rows use "model1 & model2" syntax for co-resident sets
+  - sleep_idle_seconds: -1 = never idle; 0+ = idle after N seconds
+  - load_on_startup: true = start this model on service startup
+  
+  Reference: /etc/llama-swap/config.yaml on astro-orbiter (Phase 1 artifact)

+  DESCRIPTION: Qwen3 chat template with enable_thinking unconditionally false.
+
+  This is a chat-template FILE deployed to {{ llm_models_dir }}/templates/qwen3-no-think.jinja
+  on astro-orbiter and referenced via chat-template-file in the INI preset for
+  [Qwen3-8B-Q4_K_M-no_think]. The [Qwen3-8B-Q4_K_M] section uses the model's
+  baked-in default template (thinking ON by default).
+
+  Mechanism: at the add_generation_prompt step, instead of checking
+    "enable_thinking is defined and enable_thinking is false"
+  we UNCONDITIONALLY emit the empty <think></think> prefix that suppresses CoT.
+  This is the hard-switch documented in the Qwen3 template spec and confirmed in
+  https://huggingface.co/blog/qwen-3-chat-template-deep-dive (section 1).
+
+  All other logic is identical to /opt/llama.cpp/models/templates/Qwen-Qwen3-0.6B.jinja
+  (the shipped template for Qwen3). Only the final add_generation_prompt block differs.
+
+  Added: t_664289a0 (2026-08-19, War Machine) — dual thinking deployment.

+# multica_docker
+
+Deploys [Multica](https://multica.ai/docs/self-host-quickstart) (Docker Compose self-host) and a containerised
+[Caddy](https://caddyserver.com) reverse proxy with automatic HTTPS.
+
+Mirrors the official quickstart: clones the repo, creates `.env` from `.env.example` (first run only, like
+`make selfhost`), manages specific keys in it, runs `docker-compose.selfhost.yml`, waits for `/readyz`, then
+fronts it with Caddy using the documented single-origin or two-domain config.
+
+## Requirements
+
+- Docker Engine + Compose v2 on the target (the role checks; it does not install Docker)
+- `ansible-galaxy collection install -r requirements.yml` (needs `community.docker >= 3.10`)
+- DNS for your hostname(s) pointing at the target
+
+## Quick start
+
+```bash
+cp group_vars/multica/vault.yml.example group_vars/multica/vault.yml   # fill in, then:
+ansible-vault encrypt group_vars/multica/vault.yml
+# edit inventory.ini + group_vars/multica/vars.yml
+ansible-playbook deploy_multica.yml --ask-vault-pass
+```
+
+## Key variables
+
+| Variable | Default | Notes |
+|---|---|---|
+| `multica_layout` | `single` | `single` = one hostname; `split` = app + api hostnames |
+| `multica_domain` | – | Hostname for `single` |
+| `multica_app_domain` / `multica_api_domain` | – | Hostnames for `split` |
+| `caddy_tls_mode` | `acme_http` | `acme_http`, `cloudflare_dns` (builds custom Caddy image), `internal` (Caddy CA, LAN only) |
+| `caddy_http_port` / `caddy_https_port` | `80` / `443` | Change if the host already runs nginx etc. |
+| `multica_version` / `multica_image_tag` | `main` / `latest` | Pin both to the same release tag for reproducible deploys |
+| `multica_pull_latest` | `false` | `true` pulls images every run (needed to move `latest`) |
+| `multica_backup_enabled` | `false` | `pg_dump` before changes to a running stack |
+| `multica_disable_telemetry` | `false` | Sets `DO_NOT_TRACK=true` |
+| `multica_extra_env` | `{}` | Extra `.env` keys, e.g. `ALLOW_SIGNUP: "false"` |
+
+Secrets (vault): `vault_multica_jwt_secret`, `vault_multica_postgres_password`, `vault_multica_vcs_secret_key`,
+`vault_cloudflare_api_token` (cloudflare_dns only), optional `vault_multica_resend_api_key`.
+
+## Behaviour worth knowing
+
+- **Idempotent**: `.env` is created once; only managed keys are rewritten. Compose recreates containers only when config changes.
+- **Ports 3000/8080 stay bound to 127.0.0.1** (as upstream intends). Caddy uses `network_mode: host` to reach them.
+- **Existing install?** The role overwrites `JWT_SECRET` (logs everyone out) and `POSTGRES_PASSWORD`. Postgres only reads its
+  password at first init, so for an existing database copy the *current* values from `.env` into the vault.
+- **Upgrades**: `-e multica_backup_enabled=true -e multica_pull_latest=true` (or bump `multica_version`/`multica_image_tag`).
+  Migrations run automatically on backend start; the role waits for `/readyz`.
+- **Tags**: `multica_preflight`, `multica`, `caddy`, `multica_verify`.
+
+## After the play: connect a computer
+
+The daemon runs on the machine with your AI coding tools, not the server:
+
+```bash
+multica setup self-host --server-url https://<domain> --app-url https://<domain>   # single layout
+```
+
+First login code (no email configured): `docker compose -f docker-compose.selfhost.yml logs backend | grep "Verification code"`
