Merge branch 'main' of gitea.mk-labs.cloud:rblundon/homelab

- provision-agent-host.yml: multica_pat now comes from
  vault_multica_pats[inventory_hostname_short], one daemon-<host> token per
  host. A pre_task asserts the key exists (never prints the value) so a
  missing entry fails by host name instead of as a no_log "censored".
- provision-wong-host.yml: spaceship-earth only. Grows the root partition,
  PV and LV/filesystem with growpart + community.general.lvg/lvol;
  idempotent (second run changed=0). Then applies obsidian_headless.
- roles/obsidian_headless: Obsidian's official headless Sync client
  (obsidian-headless 0.0.14) as system user obsync under a sandboxed
  systemd unit with UMask=0077. Vault at /srv/obsidian/vault: everpure/
  and wip/ obsync-only, inbox/ granted to multica via access + default
  ACLs, vault root traverse-only. Verifies the isolation as multica.
  Sign-in to Obsidian Sync stays manual (see the role README).

+# CouchDB erlangCookie Fix - Implementation Guide
+
+## Summary
+
+**Problem**: CouchDB deployment fails because `erlangCookie` is missing from the ExternalSecret configuration.
+
+**Decision**: Externalize `erlangCookie` to 1Password (pragmatic approach)
+
+**Rationale**: 
+- ExternalSecret architecture requires ownership of the entire secret
+- Mixing externalized and chart-generated fields in the same secret is not supported
+- Single-node deployment makes erlangCookie rotation unnecessary
+- This is an acceptable deviation from the pure Harbor pattern given the architectural constraints
+
+## Implementation Steps
+
+### 1. Generate erlangCookie Value
+
+```bash
+openssl rand -hex 20
+```
+
+Example output: `f4e3c2b1a9d8e7f6c5b4a3d2e1f0a9b8c7d6e5f4`
+
+### 2. Add to 1Password
+
+- **Vault**: `mk-labs`
+- **Item**: `couchdb`
+- **Field Name**: `erlang-cookie`
+- **Field Type**: password (concealed)
+- **Value**: `<paste generated value from step 1>`
+
+### 3. Update ExternalSecret Configuration
+
+File: `cluster/applications/couchdb/externalsecret.yaml`
+
+```yaml
+apiVersion: external-secrets.io/v1beta1
+kind: ExternalSecret
+metadata:
+  name: couchdb-credentials
+  namespace: couchdb
+  labels:
+    app.kubernetes.io/name: couchdb
+    app.kubernetes.io/part-of: mk-labs
+spec:
+  refreshInterval: 1h
+  secretStoreRef:
+    kind: ClusterSecretStore
+    name: onepassword-connect
+  target:
+    name: couchdb-admin
+    creationPolicy: Owner
+    template:
+      engineVersion: v2
+      data:
+        adminUsername: "admin"
+        adminPassword: "{{ .adminPassword }}"
+        cookieAuthSecret: "{{ .cookieAuthSecret }}"
+        erlangCookie: "{{ .erlangCookie }}"  # ← ADD THIS LINE
+  data:
+    - secretKey: adminPassword
+      remoteRef:
+        key: couchdb
+        property: admin-password
+    - secretKey: cookieAuthSecret
+      remoteRef:
+        key: couchdb
+        property: cookie-auth-secret
+    - secretKey: erlangCookie  # ← ADD THIS BLOCK
+      remoteRef:
+        key: couchdb
+        property: erlang-cookie
+```
+
+### 4. Update values.yaml Documentation (Optional)
+
+File: `cluster/applications/couchdb/values.yaml`
+
+Update the comment block at line 9-10:
+
+```yaml
+# Admin credentials managed via ExternalSecret
+# See externalsecret.yaml for 1Password integration
+#
+# NOTE: erlangCookie is externalized to 1Password for architectural
+# simplicity (ExternalSecret ownership model). In a pure Harbor pattern,
+# this would be chart-generated, but single-node deployment makes this
+# acceptable. The erlangCookie is treated as an immutable infrastructure
+# secret (generate once, never rotate).
+createAdminSecret: false
+extraSecretName: "couchdb-admin"
+```
+
+### 5. Commit and Push
+
+```bash
+cd ~/git/homelab
+git add cluster/applications/couchdb/externalsecret.yaml
+git add cluster/applications/couchdb/values.yaml  # if modified
+git commit -m "fix(couchdb): add erlangCookie to ExternalSecret from 1Password"
+git push origin main
+```
+
+### 6. Verify Deployment
+
+```bash
+# Watch ExternalSecret sync
+kubectl get externalsecret -n couchdb couchdb-credentials -w
+# Wait for: SecretSynced
+
+# Verify secret created with all four keys
+kubectl get secret -n couchdb couchdb-admin -o yaml
+# Should contain: adminUsername, adminPassword, cookieAuthSecret, erlangCookie
+
+# Watch ArgoCD sync
+kubectl get application -n argocd couchdb -w
+# Wait for: Healthy/Synced
+
+# Watch pod startup
+kubectl get pods -n couchdb -w
+# Wait for: Running
+
+# Test CouchDB access
+kubectl port-forward -n couchdb svc/couchdb-svc-couchdb 5984:5984 &
+curl http://localhost:5984/
+# Expected: {"couchdb":"Welcome","version":"3.5.1"}
+```
+
+## Why Not Follow Harbor Pattern Exactly?
+
+**Harbor Pattern**: Only user-facing credentials externalized, internal secrets chart-generated.
+
+**CouchDB Constraint**: ExternalSecret uses `creationPolicy: Owner`, which takes full ownership of the target secret. This prevents the Helm chart from adding auto-generated fields to the same secret.
+
+**Options Considered**:
+1. ✅ **Externalize erlangCookie** (SELECTED) - Works with current architecture
+2. ❌ Chart auto-generation - Conflicts with ExternalSecret ownership
+3. ❌ Dual-secret approach - Requires Helm chart customization
+4. ❌ Disable ExternalSecret - Loses 1Password integration for admin password
+
+**Decision**: Pragmatic approach wins. erlangCookie is treated as an infrastructure secret (generate once, never rotate), which is acceptable for a single-node deployment.
+
+## Secret Classification
+
+| Secret           | Type          | 1Password? | Rationale                          |
+|------------------|---------------|------------|------------------------------------|
+| adminUsername    | User-facing   | No*        | Static value, hardcoded in template |
+| adminPassword    | User-facing   | ✅ YES     | User login credential              |
+| cookieAuthSecret | Gray area     | ✅ YES     | Session security, periodic rotation |
+| erlangCookie     | Internal      | ✅ YES**   | Architectural constraint           |
+
+\* Hardcoded in ExternalSecret template (not fetched from 1Password)  
+\*\* Pragmatic deviation from Harbor pattern due to ExternalSecret architecture

+# 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

+**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

+   - 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

+## 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
+- **Panes**: Equal width (33% each) or responsive flex at smaller widths
+- **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)
+    ↓
+Clicks "Coverage Gaps" card → Confirms: "EMC Symmetrix not on Pure yet"
+    ↓
+Reads notes: "Customer risk-averse but willing to migrate if proven"
+    ↓
+Action: Find reference customer, prepare migration playbook for next call
+```
+
+### Flow 3: Expansion Planning
+```
+User reviewing account for renewal/expansion
+    ↓
+Glances at Scorecard: Fleet age, Opportunity size, Engagement momentum
+    ↓
+Clicks "Fleet Age" card → Sees FA-P1 refresh window in 18 months
+    ↓
+Clicks "Refresh Cycles" card → Confirms capex cycle and window
+    ↓
+Checks Stakeholder info in right pane → "Sarah (VP Storage) is champion, strong advocate"
+    ↓
+Clicks "Opportunities" tab (future) → See pipeline: Analytics consolidation (Q2 2027, $1.5M)
+    ↓
+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 |
+
+---
+

+
+---
+
+## 15. Design Review Checklist
+
+**Questions for Ryan before prototype:**
+
+1. ✅ Is the 3-pane layout clear? Does it support the 10K → ground zoom?
+2. ✅ Are the 4 KPIs the right ones, or would you change them?
+3. ✅ Does the drill-down interaction (click card → expand) feel right, or prefer modal?
+4. ✅ Should the right pane be scrollable independently, or scroll with center pane?
+5. ✅ Any major UX concerns with the navigation flow?
+6. ✅ Is the timeline component clear (horizontal bar vs. vertical list)?
+7. ✅ Color palette acceptable, or want different accent colors?
+8. ✅ Any tabs or components you'd add/remove for MVP?
+

+# Top-5 Account Intelligence Lists for Enterprise Storage SE
+
+**For:** Pre-Sales Systems Engineers at Pure Storage  
+**Focus Verticals:** Financial Services, Retail/Manufacturing  
+**Target Accounts:** Fortune 1000 / Global 2000
+
+---
+
+## 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.**

+# /opt/models: stat + EXACT-size check vs HF manifest; skip (no download, no

+# 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.

+# 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).

+# 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.

+# run this via direct ansible-playbook or ad-hoc ssh/curl/systemctl — all

+#
+# Phases (see roles/llm-inference-multimodel/README.md for detail):

+# 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.

+#
+# 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"

+#     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

+# 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
+#
+# Semaphore note: Semaphore SSH key for jarvis user is not loaded in the
+# container (known pitfall, homelab-llm-serving skill). Run via CLI with
+# id_jarvis key; document as exception per Ryan's standing CLI fallback directive.

+#   "Phi-3.5-mini-instruct-8bit" but the router only exposes the GGUF
+#   filename-derived ID "Phi-3.5-mini-instruct-Q8_0". They are the same file.
+#   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)
+#      - Qwen3.6-35B-A3B-UD-Q4_K_S (unchanged)
+#      - Meta-Llama-3.1-8B-Instruct-Q4_K_M (unchanged)
+#
+# Known upstream behavior:
+#   GH #22364: --models-preset creates an extra "default" entry in /v1/models.
+#   This is cosmetic only and does not affect model selection by name.
+#
+# Usage (from ~/git/homelab/ansible):
+#   ansible-playbook -i inventory.yml playbooks/day2_add_phi_alias.yml

+# 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.

+# Purpose:  CPU-offload Qwen2.5-Coder-14B and Meta-Llama-3.1-8B on
+#           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 /

+# DESCRIPTION: Promote llama-server-router to production on port 8002.
+#
+# Context: Router-mode shadow deployment (t_0cca74a2) validated 2026-08-12:
+#   all 4 hard gates PASSED (n_ctx 65536, tool-calling PASS, hallucination-stress
+#   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.
+#
+# Usage (from ~/git/homelab/ansible):
+#   ansible-playbook -i inventory.yml playbooks/day2_cutover_qwen_to_router.yml
+#
+# Rollback (if gates fail or any time after):
+#   ansible-playbook -i inventory.yml playbooks/day2_cutover_qwen_to_router.yml \
+#     --tags cutover_rollback
+#
+# Author: War Machine (2026-08-12, t_cd0d5388)
+# Approved by: Ryan (cutover authorization, 2026-08-12)

+# 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

+#     + 558 MiB nomic-embed = ~20.8GB total; ~3.2GB headroom on 24GB RTX 3090.

+# Purpose:  Roll back Qwen3.8-27B-Q4_K_M ctx-size from 131072 back to 65536
+#           on astro-orbiter's production router (port 8002).
+#
+# What this playbook does:
+#   1. Renders the updated llama-server-router-preset.ini.j2 (now with
+#      llm_router_qwen38_ctx_size: 65536) to
+#      /opt/llama-server-router-preset.ini.
+#   2. Restarts llama-server-router.service.
+#   3. Verifies the router loads Qwen3.8-27B at ctx=65536 in status.args.
+#
+# 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`.

+# deploy-vllm
+
+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).

+      2. Update the 1Password item:
+         `op item edit vllm --vault mk-labs 'api-key[password]=<new-value>'`
+      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.
+
+      Last rotated: see 1Password item audit log (op item get vllm --vault mk-labs).

+# expand-root-lv role
+
+Idempotent role that grows the root partition (via `growpart`), extends the
+root LVM logical volume to fill its volume group, and grows the underlying
+filesystem (ext4 or xfs).
+
+## Where this runs in the lifecycle
+
+Part of the **day0** host-provisioning lifecycle. The canonical entry
+points are:
+
+```
+playbooks/day0_expand_root_lv.yml   # standalone
+playbooks/day0_provision.yml        # umbrella (baseline + expand_root_lv)
+```
+
+Day1 application-deploy playbooks should NOT include this role —
+day0 is assumed complete before day1 begins.
+
+## Why this role exists
+
+The Ubuntu Server autoinstall template (used by the mk-labs `wed`-baked
+VM templates) provisions the root LV at roughly half the available disk
+size — a longstanding installer default that surprises every operator
+who hasn't been bitten by it before. ~90% of mk-labs VMs need this
+fix-up before they're fully useful.
+
+After a Proxmox disk grow (increasing the VM disk size), the partition
+table, physical volume, logical volume, and filesystem all need to be
+extended in sequence. This role automates the full chain.
+
+## Workflow
+
+1. **growpart** — resizes the underlying partition to claim the newly
+   provisioned disk space. Idempotent: no-op when the partition already
+   fills the disk.
+2. **pvresize** — tells the kernel/LVM about the new partition size so
+   the VG sees the additional free PEs.
+3. **lvextend** — extends the LV to claim all free PE in the VG
+   (`+100%FREE`). No-op when there's nothing to grow.
+4. **fs grow** — `resize2fs` (ext4) or `xfs_growfs` (xfs), dispatched by
+   detected filesystem type.
+
+## Idempotency
+
+- If `vg_free_count == 0`, the `lvextend` step is skipped and the
+  filesystem-grow step is also skipped (nothing to resize against).
+- If the target volume group doesn't exist on the host (e.g. a non-LVM
+  layout), the role exits cleanly via `meta: end_play`.
+- Safe to leave in a recurring playbook so future disk expansions
+  (Proxmox-side disk grow → reboot → run role) are picked up
+  automatically.
+
+## Opt-out for multi-LV hosts
+
+If a host will have a **second logical volume in the same VG** (e.g. a
+dedicated `/var/lib/postgresql` LV for a database server), this role's
+"grow root to fill VG" behavior is wrong — it will consume the free PE
+that was being reserved for the second LV.
+
+Set in `host_vars/<host>.yml`:
+
+```yaml
+expand_root_lv_skip: true
+```
+
+The day0 playbook checks this flag and skips the role cleanly.
+
+To skip only the partition growstep while keeping LV/FS expansion
+(e.g. when the partition already covers the whole disk but the LV was
+provisioned small by the template), set:
+
+```yaml
+expand_root_lv_pv_partition: undefined
+```
+
+## Defaults
+
+| Variable                      | Default       | Purpose                                             |
+|-------------------------------|---------------|-----------------------------------------------------|
+| `expand_root_lv_vg_name`      | `ubuntu-vg`   | LVM volume group name (Ubuntu installer default).   |
+| `expand_root_lv_lv_name`      | `ubuntu-lv`   | LVM logical volume name (Ubuntu installer default). |
+| `expand_root_lv_pv_partition` | `/dev/sda3`   | Partition backing the PV; grown via growpart.       |
+| `expand_root_lv_mountpoint`   | `/`           | Mountpoint of the filesystem to grow.               |
+
+Override the VG/LV/PV names in `host_vars/<host>.yml` for hosts that use a
+different layout.
+
+## Limitations
+
+- The `growpart` step requires the `cloud-guest-utils` package. The role
+  installs it automatically on Debian/Ubuntu hosts when
+  `expand_root_lv_pv_partition` is defined.
+- Only supports ext4 and xfs filesystems. Other filesystem types (btrfs,
+  etc.) are left as a future enhancement.

+    Idempotent role that extends the root LVM logical volume to fill its
+    volume group and grows the underlying filesystem (ext4 or xfs). Fixes
+    the half-disk LV that the Ubuntu Server autoinstall template ships
+    with by default.
