 ## Testing
 
+**ALWAYS use `scripts/run_tests.sh`** — do not call `pytest` directly. The script enforces
+hermetic environment parity with CI (unset credential vars, TZ=UTC, LANG=C.UTF-8,
+4 xdist workers matching GHA ubuntu-latest). Direct `pytest` on a 16+ core
+developer machine with API keys set diverges from CI in ways that have caused
+multiple "works locally, fails in CI" incidents (and the reverse).

 ```
 
+### Why the wrapper (and why the old "just call pytest" doesn't work)
+
+Five real sources of local-vs-CI drift the script closes:
+
+| | Without wrapper | With wrapper |
+|---|---|---|
+| Provider API keys | Whatever is in your env (auto-detects pool) | All `*_API_KEY`/`*_TOKEN`/etc. unset |
+| HOME / `~/.hermes/` | Your real config+auth.json | Temp dir per test |
+| Timezone | Local TZ (PDT etc.) | UTC |
+| Locale | Whatever is set | C.UTF-8 |
+| xdist workers | `-n auto` = all cores (20+ on a workstation) | `-n 4` matching CI |
+
+`tests/conftest.py` also enforces points 1-4 as an autouse fixture so ANY pytest
+invocation (including IDE integrations) gets hermetic behavior — but the wrapper
+is belt-and-suspenders.
+
+### Running without the wrapper (only if you must)
+
+If you can't use the wrapper (e.g. on Windows or inside an IDE that shells
+pytest directly), at minimum activate the venv and pass `-n 4`:
+
+```bash
+source venv/bin/activate
+python -m pytest tests/ -q -n 4
+```
+
+Worker count above 4 will surface test-ordering flakes that CI never sees.
+
 Always run the full suite before pushing changes.

+    #      download — unauthenticated httpx sees 403 Forbidden.
+    #      (issue #8242)
+    #   2. Some user environments (VPNs, corporate DNS, tunnels) resolve
+    #      ``cdn.discordapp.com`` to private-looking IPs that our
+    #      ``is_safe_url`` guard classifies as SSRF risks. Routing the
+    #      fetch through discord.py's own HTTP client handles DNS
+    #      internally so our guard isn't consulted for the attachment
+    #      path. (issue #6587)
+    #
+    # If ``att.read()`` is unavailable (unexpected object shape / test
+    # stub) or the bot session fetch fails, we fall back to the existing
+    # SSRF-gated URL downloaders. The fallback keeps defense-in-depth

+# Concept Diagrams
+
+Generate production-quality SVG diagrams with a unified flat, minimal design system. Output is a single self-contained HTML file that renders identically in any modern browser, with automatic light/dark mode.
+
+## Scope
+
+**Best suited for:**
+- Physics setups, chemistry mechanisms, math curves, biology
+- Physical objects (aircraft, turbines, smartphones, mechanical watches, cells)
+- Anatomy, cross-sections, exploded layer views
+- Floor plans, architectural conversions
+- Narrative journeys (lifecycle of X, process of Y)
+- Hub-spoke system integrations (smart city, IoT networks, electricity grids)
+- Educational / textbook-style visuals in any domain
+- Quantitative charts (grouped bars, energy profiles)
+
+**Look elsewhere first for:**
+- Dedicated software / cloud infrastructure architecture with a dark tech aesthetic (consider `architecture-diagram` if available)
+- Hand-drawn whiteboard sketches (consider `excalidraw` if available)
+- Animated explainers or video output (consider an animation skill)
+
+If a more specialized skill is available for the subject, prefer that. If none fits, this skill can serve as a general-purpose SVG diagram fallback — the output will carry the clean educational aesthetic described below, which is a reasonable default for almost any subject.
+
+## Workflow
+
+1. Decide on the diagram type (see Diagram Types below).
+2. Lay out components using the Design System rules.
+3. Write the full HTML page using `templates/template.html` as the wrapper — paste your SVG where the template says `<!-- PASTE SVG HERE -->`.
+4. Save as a standalone `.html` file (for example `~/my-diagram.html` or `./my-diagram.html`).
+5. User opens it directly in a browser — no server, no dependencies.
+
+Optional: if the user wants a browsable gallery of multiple diagrams, see "Local Preview Server" at the bottom.
+
+Load the HTML template:
+```
+skill_view(name="concept-diagrams", file_path="templates/template.html")
+```
+
+The template embeds the full CSS design system (`c-*` color classes, text classes, light/dark variables, arrow marker styles). The SVG you generate relies on these classes being present on the hosting page.
+
+---
+
+## Design System
+
+### Philosophy
+
+- **Flat**: no gradients, drop shadows, blur, glow, or neon effects.
+- **Minimal**: show the essential. No decorative icons inside boxes.
+- **Consistent**: same colors, spacing, typography, and stroke widths across every diagram.
+- **Dark-mode ready**: all colors auto-adapt via CSS classes — no per-mode SVG.
+
+### Color Palette
+
+9 color ramps, each with 7 stops. Put the class name on a `<g>` or shape element; the template CSS handles both modes.
+
+| Class      | 50 (lightest) | 100     | 200     | 400     | 600     | 800     | 900 (darkest) |
+|------------|---------------|---------|---------|---------|---------|---------|---------------|
+| `c-purple` | #EEEDFE | #CECBF6 | #AFA9EC | #7F77DD | #534AB7 | #3C3489 | #26215C |
+| `c-teal`   | #E1F5EE | #9FE1CB | #5DCAA5 | #1D9E75 | #0F6E56 | #085041 | #04342C |
+| `c-coral`  | #FAECE7 | #F5C4B3 | #F0997B | #D85A30 | #993C1D | #712B13 | #4A1B0C |
+| `c-pink`   | #FBEAF0 | #F4C0D1 | #ED93B1 | #D4537E | #993556 | #72243E | #4B1528 |
+| `c-gray`   | #F1EFE8 | #D3D1C7 | #B4B2A9 | #888780 | #5F5E5A | #444441 | #2C2C2A |
+| `c-blue`   | #E6F1FB | #B5D4F4 | #85B7EB | #378ADD | #185FA5 | #0C447C | #042C53 |
+| `c-green`  | #EAF3DE | #C0DD97 | #97C459 | #639922 | #3B6D11 | #27500A | #173404 |
+| `c-amber`  | #FAEEDA | #FAC775 | #EF9F27 | #BA7517 | #854F0B | #633806 | #412402 |
+| `c-red`    | #FCEBEB | #F7C1C1 | #F09595 | #E24B4A | #A32D2D | #791F1F | #501313 |
+
+#### Color Assignment Rules
+
+Color encodes **meaning**, not sequence. Never cycle through colors like a rainbow.
+
+- Group nodes by **category** — all nodes of the same type share one color.
+- Use `c-gray` for neutral/structural nodes (start, end, generic steps, users).
+- Use **2-3 colors per diagram**, not 6+.
+- Prefer `c-purple`, `c-teal`, `c-coral`, `c-pink` for general categories.
+- Reserve `c-blue`, `c-green`, `c-amber`, `c-red` for semantic meaning (info, success, warning, error).
+
+Light/dark stop mapping (handled by the template CSS — just use the class):
+- Light mode: 50 fill + 600 stroke + 800 title / 600 subtitle
+- Dark mode:  800 fill + 200 stroke + 100 title / 200 subtitle
+
+### Typography
+
+Only two font sizes. No exceptions.
+
+| Class | Size | Weight | Use |
+|-------|------|--------|-----|
+| `th`  | 14px | 500    | Node titles, region labels |
+| `ts`  | 12px | 400    | Subtitles, descriptions, arrow labels |
+| `t`   | 14px | 400    | General text |
+
+- **Sentence case always.** Never Title Case, never ALL CAPS.
+- Every `<text>` MUST carry a class (`t`, `ts`, or `th`). No unclassed text.
+- `dominant-baseline="central"` on all text inside boxes.
+- `text-anchor="middle"` for centered text in boxes.
+
+**Width estimation (approx):**
+- 14px weight 500: ~8px per character
+- 12px weight 400: ~6.5px per character
+- Always verify: `box_width >= (char_count × px_per_char) + 48` (24px padding each side)
+
+### Spacing & Layout
+
+- **ViewBox**: `viewBox="0 0 680 H"` where H = content height + 40px buffer.
+- **Safe area**: x=40 to x=640, y=40 to y=(H-40).
+- **Between boxes**: 60px minimum gap.
+- **Inside boxes**: 24px horizontal padding, 12px vertical padding.
+- **Arrowhead gap**: 10px between arrowhead and box edge.
+- **Single-line box**: 44px height.
+- **Two-line box**: 56px height, 18px between title and subtitle baselines.
+- **Container padding**: 20px minimum inside every container.
+- **Max nesting**: 2-3 levels deep. Deeper gets unreadable at 680px width.
+
+### Stroke & Shape
+
+- **Stroke width**: 0.5px on all node borders. Not 1px, not 2px.
+- **Rect rounding**: `rx="8"` for nodes, `rx="12"` for inner containers, `rx="16"` to `rx="20"` for outer containers.
+- **Connector paths**: MUST have `fill="none"`. SVG defaults to `fill: black` otherwise.
+
+### Arrow Marker
+
+Include this `<defs>` block at the start of **every** SVG:
+
+```xml
+<defs>
+  <marker id="arrow" viewBox="0 0 10 10" refX="8" refY="5"
+          markerWidth="6" markerHeight="6" orient="auto-start-reverse">
+    <path d="M2 1L8 5L2 9" fill="none" stroke="context-stroke"
+          stroke-width="1.5" stroke-linecap="round" stroke-linejoin="round"/>
+  </marker>
+</defs>
+```
+
+Use `marker-end="url(#arrow)"` on lines. The arrowhead inherits the line color via `context-stroke`.
+
+### CSS Classes (Provided by the Template)
+
+The template page provides:
+
+- Text: `.t`, `.ts`, `.th`
+- Neutral: `.box`, `.arr`, `.leader`, `.node`
+- Color ramps: `.c-purple`, `.c-teal`, `.c-coral`, `.c-pink`, `.c-gray`, `.c-blue`, `.c-green`, `.c-amber`, `.c-red` (all with automatic light/dark mode)
+
+You do **not** need to redefine these — just apply them in your SVG. The template file contains the full CSS definitions.
+
+---
+
+## SVG Boilerplate
+
+Every SVG inside the template page starts with this exact structure:
+
+```xml
+<svg width="100%" viewBox="0 0 680 {HEIGHT}" xmlns="http://www.w3.org/2000/svg">
+  <defs>
+    <marker id="arrow" viewBox="0 0 10 10" refX="8" refY="5"
+            markerWidth="6" markerHeight="6" orient="auto-start-reverse">
+      <path d="M2 1L8 5L2 9" fill="none" stroke="context-stroke"
+            stroke-width="1.5" stroke-linecap="round" stroke-linejoin="round"/>
+    </marker>
+  </defs>
+
+  <!-- Diagram content here -->
+
+</svg>
+```
+
+Replace `{HEIGHT}` with the actual computed height (last element bottom + 40px).
+
+### Node Patterns
+
+**Single-line node (44px):**
+```xml
+<g class="node c-blue">
+  <rect x="100" y="20" width="180" height="44" rx="8" stroke-width="0.5"/>
+  <text class="th" x="190" y="42" text-anchor="middle" dominant-baseline="central">Service name</text>
+</g>
+```
+
+**Two-line node (56px):**
+```xml
+<g class="node c-teal">
+  <rect x="100" y="20" width="200" height="56" rx="8" stroke-width="0.5"/>
+  <text class="th" x="200" y="38" text-anchor="middle" dominant-baseline="central">Service name</text>
+  <text class="ts" x="200" y="56" text-anchor="middle" dominant-baseline="central">Short description</text>
+</g>
+```
+
+**Connector (no label):**
+```xml
+<line x1="200" y1="76" x2="200" y2="120" class="arr" marker-end="url(#arrow)"/>
+```
+
+**Container (dashed or solid):**
+```xml
+<g class="c-purple">
+  <rect x="40" y="92" width="600" height="300" rx="16" stroke-width="0.5"/>
+  <text class="th" x="66" y="116">Container label</text>
+  <text class="ts" x="66" y="134">Subtitle info</text>
+</g>
+```
+
+---
+
+## Diagram Types
+
+Choose the layout that fits the subject:
+
+1. **Flowchart** — CI/CD pipelines, request lifecycles, approval workflows, data processing. Single-direction flow (top-down or left-right). Max 4-5 nodes per row.
+2. **Structural / Containment** — Cloud infrastructure nesting, system architecture with layers. Large outer containers with inner regions. Dashed rects for logical groupings.
+3. **API / Endpoint Map** — REST routes, GraphQL schemas. Tree from root, branching to resource groups, each containing endpoint nodes.
+4. **Microservice Topology** — Service mesh, event-driven systems. Services as nodes, arrows for communication patterns, message queues between.
+5. **Data Flow** — ETL pipelines, streaming architectures. Left-to-right flow from sources through processing to sinks.
+6. **Physical / Structural** — Vehicles, buildings, hardware, anatomy. Use shapes that match the physical form — `<path>` for curved bodies, `<polygon>` for tapered shapes, `<ellipse>`/`<circle>` for cylindrical parts, nested `<rect>` for compartments. See `references/physical-shape-cookbook.md`.
+7. **Infrastructure / Systems Integration** — Smart cities, IoT networks, multi-domain systems. Hub-spoke layout with central platform connecting subsystems. Semantic line styles (`.data-line`, `.power-line`, `.water-pipe`, `.road`). See `references/infrastructure-patterns.md`.
+8. **UI / Dashboard Mockups** — Admin panels, monitoring dashboards. Screen frame with nested chart/gauge/indicator elements. See `references/dashboard-patterns.md`.
+
+For physical, infrastructure, and dashboard diagrams, load the matching reference file before generating — each one provides ready-made CSS classes and shape primitives.
+
+---
+
+## Validation Checklist
+
+Before finalizing any SVG, verify ALL of the following:
+
+1. Every `<text>` has class `t`, `ts`, or `th`.
+2. Every `<text>` inside a box has `dominant-baseline="central"`.
+3. Every connector `<path>` or `<line>` used as arrow has `fill="none"`.
+4. No arrow line crosses through an unrelated box.
+5. `box_width >= (longest_label_chars × 8) + 48` for 14px text.
+6. `box_width >= (longest_label_chars × 6.5) + 48` for 12px text.
+7. ViewBox height = bottom-most element + 40px.
+8. All content stays within x=40 to x=640.
+9. Color classes (`c-*`) are on `<g>` or shape elements, never on `<path>` connectors.
+10. Arrow `<defs>` block is present.
+11. No gradients, shadows, blur, or glow effects.
+12. Stroke width is 0.5px on all node borders.
+
+---
+
+## Output & Preview
+
+### Default: standalone HTML file
+
+Write a single `.html` file the user can open directly. No server, no dependencies, works offline. Pattern:
+
+```python
+# 1. Load the template
+template = skill_view("concept-diagrams", "templates/template.html")
+
+# 2. Fill in title, subtitle, and paste your SVG
+html = template.replace(
+    "<!-- DIAGRAM TITLE HERE -->", "SN2 reaction mechanism"
+).replace(
+    "<!-- OPTIONAL SUBTITLE HERE -->", "Bimolecular nucleophilic substitution"
+).replace(
+    "<!-- PASTE SVG HERE -->", svg_content
+)
+
+# 3. Write to a user-chosen path (or ./ by default)
+write_file("./sn2-mechanism.html", html)
+```
+
+Tell the user how to open it:
+
+```
+# macOS
+open ./sn2-mechanism.html
+# Linux
+xdg-open ./sn2-mechanism.html
+```
+
+### Optional: local preview server (multi-diagram gallery)
+
+Only use this when the user explicitly wants a browsable gallery of multiple diagrams.
+
+**Rules:**
+- Bind to `127.0.0.1` only. Never `0.0.0.0`. Exposing diagrams on all network interfaces is a security hazard on shared networks.
+- Pick a free port (do NOT hard-code one) and tell the user the chosen URL.
+- The server is optional and opt-in — prefer the standalone HTML file first.
+
+Recommended pattern (lets the OS pick a free ephemeral port):
+
+```bash
+# Put each diagram in its own folder under .diagrams/
+mkdir -p .diagrams/sn2-mechanism
+# ...write .diagrams/sn2-mechanism/index.html...
+
+# Serve on loopback only, free port
+cd .diagrams && python3 -c "
+import http.server, socketserver
+with socketserver.TCPServer(('127.0.0.1', 0), http.server.SimpleHTTPRequestHandler) as s:
+    print(f'Serving at http://127.0.0.1:{s.server_address[1]}/')
+    s.serve_forever()
+" &
+```
+
+If the user insists on a fixed port, use `127.0.0.1:<port>` — still never `0.0.0.0`. Document how to stop the server (`kill %1` or `pkill -f "http.server"`).
+

+# Apartment Floor Plan: 3 BHK to 4 BHK Conversion
+
+An architectural floor plan showing a 1,500 sq ft apartment with proposed modifications to convert from 3 BHK to 4 BHK. Demonstrates architectural drawing conventions, room layouts, proposed changes with dotted lines, and area comparison tables.
+
+## Key Patterns Used
+
+- **Architectural floor plan**: Top-down view with walls, doors, windows
+- **Proposed modifications**: Dotted red lines for new walls
+- **Room color coding**: Light fills to distinguish room types
+- **Circulation paths**: Arrows showing new access routes
+- **Data table**: Before/after area comparison with highlighting
+- **Architectural symbols**: North arrow, scale bar, door swings
+
+## Diagram Type
+
+This is an **architectural floor plan** with:
+- **Plan view**: Top-down orthographic projection
+- **Overlay technique**: Existing structure + proposed changes
+- **Quantitative data**: Area measurements and comparison table

+
+## Layout Notes
+
+- **ViewBox**: 800×780 (portrait for floor plan + table)
+- **Scale**: 10px = 1 foot (apartment ~50ft × 33ft)
+- **Floor plan origin**: Offset at (50, 60) for margins
+- **Wall thickness**: 6px outer, 3px inner (represents ~6" walls)
+- **Room labels**: Centered in each room with area below
+- **Table placement**: Below floor plan with full width
+
+## Color Coding
+
+| Element | Color | Usage |
+|---------|-------|-------|
+| Proposed walls | Red (#A32D2D) dotted | New construction |
+| New room fill | Red 15% opacity | Bedroom 4 area |
+| Circulation | Green (#3B6D11) | New access path |
+| Window glass | Blue (#378ADD) | Glass indication |
+| Bedrooms | Purple/Teal/Amber tints | Room differentiation |
+| Wet areas | Blue tint | Bathrooms |
+| Living | Coral tint | Common areas |
+
+## When to Use This Pattern
+
+Use this diagram style for:
+- Apartment/house floor plans
+- Office layout planning
+- Renovation proposals showing before/after
+- Space planning with area calculations
+- Real estate marketing materials
+- Interior design presentations
+- Building permit documentation

+# Automated Password Reset Flow
+
+A two-section flowchart tracing the full user journey for a web application password reset: the initial request phase (forgot password → email check → token generation) and the reset-form phase (link click → new password entry → token/password validation). Demonstrates multi-exit decision diamonds, a three-column branching layout, a loop-back path, and a cross-section separator arrow.
+
+## Key Patterns Used
+
+- **Three-column layout**: Left column (error/terminal branches at cx=115), center column (main happy path at cx=340), right column (expired-token branch at cx=552) — allows side branches to live at the same y-level as center nodes without overlap
+- **Decision diamonds with `<polygon>`**: Each decision uses a `<g class="decision">` wrapper containing a `<polygon>` and centered `<text>`; the diamond points are computed as `cx±hw, cy±hh` (hw=100, hh=28)
+- **Pill-shaped terminals**: Start and end nodes use `rx=22` on their `<rect>` to signal entry/exit points; all mid-flow process nodes use `rx=8`
+- **Three-branch decision paths**: Each diamond has a "Yes" branch (down, short `<line>`) and a "No" branch (`<path>` going horizontal then vertical to a side column)
+- **Loop-back path**: Mismatch error node loops back to the password-entry node via a routing corridor at x=215 — a 5-px gap between the left column (right edge x=210) and center column (left edge x=220); the path exits the bottom of the error node, drops below it, travels right to x=215, then goes up to the target node's center y, then right 5 px into the node's left edge
+- **Section separator**: A dashed horizontal `<line>` at y=452 splits the two phases; the connecting arrow crosses it with a faded label ("user receives email") to preserve flow continuity
+- **Italic annotation**: The exact UX copy for the generic message ("If that email exists…") is shown as a faded italic `ts` text block below the left-branch terminal node
+- **Legend row**: Five inline swatches (gray, purple, teal, red, amber diamond) at the bottom explain the color-to-role mapping

+## Color Assignments
+
+| Element | Color | Reason |
+|---------|-------|--------|
+| Start / end terminals | `c-gray` | Neutral entry and exit points |
+| User actions (enter email, click link, enter password) | `c-gray` | User-facing steps with no system processing |
+| Generic message + request-handled terminal | `c-gray` | Intentionally neutral — the security message must not reveal data |
+| Generate & store token | `c-purple` | Backend system operations |
+| Send reset email | `c-teal` | Positive external action (outbound communication) |
+| Token expired error | `c-red` | Failure / blocking error state |
+| Password mismatch error | `c-red` | Validation failure |
+| Reset password + success | `c-teal` / `c-green` | Positive outcome: teal for the action, green pill for the terminal |
+| Decision diamonds | `c-amber` (custom `.decision`) | Warning / branch point — matches amber semantic meaning |
+
+## Layout Notes
+
+- **ViewBox**: 680×960 — tall flowchart with two phases
+- **Three-column structure**: Left (cx=115), center (cx=340), right (cx=552) — each branch stays within its column; only `<path>` arrows cross column boundaries
+- **Diamond formula**: `<polygon points="cx,cy-hh cx+hw,cy cx,cy+hh cx-hw,cy"/>` with hw=100, hh=28 gives a 200×56px diamond that sits flush with the center column (x=220–460)
+- **Branch routing pattern**: "No" paths use `<path d="M left_point,cy L side_cx,cy L side_cx,node_top">` — one horizontal segment + one vertical segment, no curves needed
+- **Loop corridor**: The 5-px gap at x=210–220 between left and center columns provides a clean vertical channel for the loop-back path without any node overlap; the path exits node bottom, drops 20px, goes right to x=215, climbs to target y, enters from left
+- **Section separator**: A dashed `<line>` at y=452 with `stroke-dasharray="8 5"` provides a visual phase break; the single connecting arrow crosses it at center, with a faded label on the arrow
+- **Pill terminals**: `rx=22` (half the 44px node height) produces a perfect capsule/pill shape — use this consistently for all start/end terminals
+- **Error annotation**: The exact UX copy is rendered as faded (`opacity=".45"`) italic `ts` text below the relevant node, keeping it informative without cluttering the flow

+# Autonomous LLM Research Agent Flow
+
+A multi-section flowchart showing Karpathy's autoresearch framework: human-agent handoff, the autonomous experiment loop with keep/discard decision branching, and the modifiable training pipeline. Demonstrates loop-back arrows, convergent decision paths, and semantic color coding for outcomes.
+
+## Key Patterns Used
+
+- **Three-section layout**: Setup row, main loop container, and detail container — each visually distinct
+- **Neutral dashed containers**: Loop and training pipeline use `var(--bg-secondary)` fill with dashed borders to recede behind colored content nodes
+- **Decision branching with convergence**: "val_bpb improved?" splits into Keep (green) and Discard (red), then both converge back to "Log to results.tsv"
+- **Loop-back arrow**: Dashed path with rounded corners on the right side of the container showing infinite repetition
+- **Semantic color for outcomes**: Green = improvement (keep), Red = no improvement (discard) — not arbitrary decoration
+- **Highlighted key step**: "Run training" uses `c-coral` to visually distinguish the most important step from other `c-teal` actions
+- **Horizontal pipeline flow**: Training details section uses left-to-right arrow-connected nodes (GPT → MuonAdamW → Evaluation)
+- **Footer metadata**: Fixed constraints shown as subtle centered text below the pipeline nodes
+- **Legend row**: Color key at the bottom explaining what each color means

+## Color Assignments
+
+| Element | Color | Reason |
+|---------|-------|--------|

+| AI agent | `c-purple` | The active intelligent actor |
+| Loop action steps | `c-teal` | Agent's analytical/editing actions |

+
+## Layout Notes
+
+- **ViewBox**: 680×920 (standard width, tall for 3 sections)
+- **Three sections**: Setup row (y=30–98), loop container (y=142–670), training details (y=710–880)
+- **Container style**: Dashed border (`stroke-dasharray="6 4"`), neutral fill (`var(--bg-secondary)`), `stroke-width="1"` — not colored, so inner nodes pop
+- **Loop-back arrow**: Dashed `<path>` with quadratic curves (`Q`) at corners for smooth rounded turns, running up the right side of the loop container from "Log" back to "Read code"
+- **Decision pattern**: Single question node ("val_bpb improved?") with diagonal arrows to Keep/Discard, then convergent diagonal arrows back to "Log to results.tsv"
+- **Decision labels**: "yes"/"no" labels placed along the diagonal arrows with `opacity=".6"` to stay subtle
+- **Key step highlight**: "Run training" uses `c-coral` while surrounding steps use `c-teal`, drawing the eye to the most important step
+- **Horizontal sub-flow**: Training pipeline uses left-to-right arrow-connected nodes (GPT model → MuonAdamW → Evaluation)
+- **Footer metadata**: Fixed constraints (data, vocab, budget, context) shown as a single centered `ts` text line with `opacity=".5"`
+- **Legend**: Four color swatches at the bottom explaining the semantic meaning of each color used

+# Journey of a Banana: From Tree to Smoothie
+
+A narrative journey diagram following a single banana across 3,000 miles and 3 weeks, from harvest in Costa Rica to a smoothie in the consumer's kitchen. Demonstrates storytelling through visualization, winding path layout, and progressive state changes.
+
+## Key Patterns Used
+
+- **Winding journey path**: S-curve connecting all stages visually
+- **Location markers**: Country flags and place names for geographic context
+- **Progressive state changes**: Banana color changes (green → yellow → brown → frozen → smoothie)
+- **Narrative details**: Fun elements like spider check, stickers, price tags
+- **Timeline**: Bottom timeline showing duration of journey
+- **Environmental context**: Ocean waves, gas clouds, store awning

+## Layout Notes
+
+- **ViewBox**: 850×680 (tall for winding path)
+- **Path style**: S-curve winding path connects all 7 stages
+- **Location labels**: Country flags + place names anchor geographic context
+- **State progression**: Same object (banana) shown in different states throughout
+- **Timeline**: Horizontal timeline at bottom shows journey duration
+- **Narrative elements**: Fun details (spider, stickers, price tags) add storytelling value
+- **Environmental context**: Ocean waves, gas clouds, awnings create sense of place

+# Commercial Aircraft Structure
+
+A physical/structural diagram showing an aircraft side profile using appropriate SVG shapes beyond rectangles - paths, polygons, ellipses for realistic representation.
+
+## Key Patterns Used
+
+- **Path elements**: Curved fuselage body with nose cone using quadratic bezier curves
+- **Polygon elements**: Tapered wing shape, triangular stabilizers, control surfaces
+- **Ellipse elements**: Engines (cylinders), wheels (circles)
+- **Line elements**: Landing gear struts, leader lines for labels
+- **Dashed strokes**: Interior sections (fuel tank), movable control surfaces (rudder, elevator)
+- **Layered composition**: Cabin sections drawn inside the fuselage shape
+- **Leader lines with labels**: Connect labels to components they describe

+## Shape Selection Guide
+
+| Physical form | SVG element | Example |
+|---------------|-------------|---------|
+| Curved body | `<path>` with Q (quadratic) or C (cubic) curves | Fuselage, nose cone |
+| Tapered/angular | `<polygon>` | Wings, stabilizers |
+| Cylindrical | `<ellipse>` | Engines, wheels, tanks |
+| Linear structure | `<line>` | Struts, pylons, gear legs |
+| Internal sections | `<rect>` inside parent shape | Cabin classes |
+| Dashed boundaries | `stroke-dasharray` on any shape | Fuel tanks, control surfaces |
+
+## Layout Notes
+
+- **ViewBox**: 680×400 (wider aspect ratio suits side profile)
+- **Layering**: Draw outer structures first, then interior details on top
+- **Leader lines**: Use `.leader` class (dashed) to connect labels to components
+- **Text sizes**: Use `.tl` (10px) for component labels, `.ts` (12px) for section labels
+- **Semantic colors**: Group by system (structure=blue, propulsion=coral, fuel=amber, etc.)

+# Out-of-Order CPU Core Microarchitecture
+
+A structural diagram showing the internal pipeline stages of a modern superscalar out-of-order CPU core. Demonstrates multi-stage vertical flow with parallel paths, fan-out patterns for execution ports, and a separate memory hierarchy sidebar.
+
+## Key Patterns Used
+
+- **Multi-stage vertical flow**: Six pipeline stages (Front End → Rename → Schedule → Execute → Retire)
+- **Parallel decode paths**: Main decode and µop cache bypass (dashed line for cache hit)
+- **Container grouping**: Logical stages grouped in colored containers
+- **Fan-out pattern**: Single scheduler dispatching to 6 execution ports
+- **Sidebar layout**: Memory hierarchy placed in separate column on right
+- **Stage labels**: Left-aligned labels indicating pipeline phase
+- **Color-coded semantics**: Different colors for each functional unit category
+
+## Diagram Type
+
+This is a **hybrid structural/flow** diagram:
+- **Flow aspect**: Instructions move top-to-bottom through pipeline stages
+- **Structural aspect**: Components are grouped by function (rename unit, execution cluster)
+- **Sidebar**: Memory hierarchy is architecturally separate but connected via data paths
+
+## Pipeline Stage Breakdown
+
+### Front End (Purple)
+```xml
+<!-- Fetch Unit -->
+<g class="node c-purple">
+  <rect x="40" y="70" width="140" height="56" rx="8" stroke-width="0.5"/>

+  <text class="ts" x="310" y="110" text-anchor="middle" dominant-baseline="central">x86 → µops, 6-wide</text>
+</g>
+```
+
+### µop Cache Bypass Path (Teal)
+The µop cache (Decoded Stream Buffer) provides an alternate path that bypasses the complex decoder:
+
+```xml
+<!-- µop Cache parallel to decode -->
+<g class="node c-teal">
+  <rect x="230" y="150" width="160" height="50" rx="8" stroke-width="0.5"/>

+  <text class="ts" x="310" y="186" text-anchor="middle" dominant-baseline="central">4K entries, 8-wide</text>
+</g>
+
+<!-- Dashed bypass path indicating cache hit -->
+<path d="M180 110 L205 110 L205 175 L230 175" fill="none" class="arr" 
+      stroke-dasharray="4 3" marker-end="url(#arrow)"/>
+<text class="tx" x="164" y="148" opacity=".6">hit</text>
+```
+
+### Rename/Allocate Container (Coral)
+Groups related rename components in a container:
+
+```xml
+<!-- Outer container -->
+<g class="c-coral">
+  <rect x="40" y="250" width="530" height="130" rx="12" stroke-width="0.5"/>

+
+### Scheduler Fan-Out Pattern (Amber → Teal)
+Single unified scheduler dispatching to multiple execution ports:
+
+```xml
+<!-- Unified Scheduler -->

+  <text class="ts" x="305" y="456" text-anchor="middle" dominant-baseline="central">97 entries, out-of-order dispatch</text>
+</g>
+
+<!-- Fan-out arrows to 6 ports -->
+<line x1="170" y1="470" x2="90" y2="540" class="arr" marker-end="url(#arrow)"/>

+<line x1="420" y1="470" x2="490" y2="540" class="arr" marker-end="url(#arrow)"/>
+```
+
+### Execution Port Box Pattern
+Compact boxes showing port number and capabilities:
+
+```xml
+<!-- Execution port with multi-line capability -->
+<g class="node c-teal">
+  <rect x="55" y="540" width="70" height="64" rx="6" stroke-width="0.5"/>
+  <text class="th" x="90" y="560" text-anchor="middle" dominant-baseline="central">Port 0</text>

+  <text class="tx" x="90" y="590" text-anchor="middle" dominant-baseline="central">DIV</text>
+</g>
+```
+
+### Reorder Buffer (Pink)
+Wide horizontal bar at bottom showing retirement:
+
+```xml
+<g class="c-pink">
+  <rect x="40" y="670" width="530" height="40" rx="10" stroke-width="0.5"/>
+  <text class="th" x="305" y="694" text-anchor="middle" dominant-baseline="central">Reorder buffer (ROB) — 512 entries, 8-wide retire</text>
+</g>
+```
+
+### Memory Hierarchy Sidebar (Blue)
+Separate column showing cache levels:
+
+```xml
+<!-- Container -->
+<g class="c-blue">
+  <rect x="600" y="30" width="190" height="360" rx="16" stroke-width="0.5"/>
+  <text class="th" x="695" y="54" text-anchor="middle">Memory hierarchy</text>
+</g>
+
+<!-- Cache levels stacked vertically -->
+<g class="node c-blue">

+  <text class="th" x="695" y="88" text-anchor="middle" dominant-baseline="central">L1-I cache</text>
+  <text class="ts" x="695" y="106" text-anchor="middle" dominant-baseline="central">32 KB, 8-way</text>
+</g>
+<!-- Additional levels follow same pattern -->
+```
+
+## Connection Patterns
+
+### Instruction Fetch Path
+Horizontal arrow from L1-I cache to fetch unit:
+```xml
+<path d="M620 95 L200 95" fill="none" class="arr" marker-end="url(#arrow)"/>
+<text class="tx" x="410" y="88" text-anchor="middle" opacity=".6">instruction fetch</text>
+```
+
+### Load/Store Path
+Complex path from execution ports to L1-D cache:
+```xml
+<path d="M250 604 L250 640 L580 640 L580 160 L620 160" fill="none" class="arr" marker-end="url(#arrow)"/>
+<text class="tx" x="415" y="652" text-anchor="middle" opacity=".6">load / store</text>
+```
+
+### Commit Path (dashed)
+Dashed line showing write-back from ROB to register file:
+```xml
+<path d="M550 690 L580 690 L580 445 L595 445" fill="none" class="arr" stroke-dasharray="4 3"/>
+<text class="tx" x="590" y="578" opacity=".6" transform="rotate(-90 590 578)">commit</text>
+```
+
+### Path Merge (Decode + µop Cache)
+Two paths converging before rename:
+```xml
+<line x1="390" y1="98" x2="430" y2="98" class="arr"/>
+<line x1="390" y1="175" x2="430" y2="175" class="arr"/>
+<path d="M430 98 L430 175" fill="none" stroke="var(--text-secondary)" stroke-width="1.5"/>
+<line x1="430" y1="136" x2="470" y2="136" class="arr" marker-end="url(#arrow)"/>
+```
+
+## Text Classes
+
+This diagram uses an additional text class for very small labels:
+
+```css
+.tx { font-family: system-ui, -apple-system, sans-serif; font-size: 10px; fill: var(--text-secondary); }
+```
+
+Used for:
+- Execution port capability labels (ALU, Branch, Load, etc.)
+- Connection labels (instruction fetch, load/store, commit)
+- DRAM latency annotation
+
+## Color Semantic Mapping
+
+| Color | Stage | Components |
+|-------|-------|------------|
+| `c-purple` | Front end | Fetch, Branch predictor, Decode |
+| `c-teal` | Execution | µop cache, Execution ports |
+| `c-coral` | Rename | RAT, Physical RF, Free list |
+| `c-amber` | Schedule | Unified scheduler |
+| `c-pink` | Retire | Reorder buffer |
+| `c-blue` | Memory | L1-I, L1-D, L2, DRAM |
+| `c-gray` | External | Off-chip DRAM |
+
+## Layout Notes
+
+- **ViewBox**: 820×720 (taller than wide for vertical pipeline flow)
+- **Main pipeline**: x=40 to x=570 (530px width)
+- **Memory sidebar**: x=600 to x=790 (190px width)
+- **Stage labels**: x=30, left-aligned, 50% opacity
+- **Vertical spacing**: ~80-100px between major stages
+- **Container padding**: 20px inside containers
+- **Port spacing**: 80px between execution port centers
+- **Legend**: Bottom-right of memory sidebar, explains color coding
+
+## Architectural Details Shown
+
+| Component | Specification | Notes |
+|-----------|---------------|-------|
+| Fetch | 6-wide, 32B/cycle | Typical modern Intel/AMD |
+| Decode | 6-wide, x86→µops | Complex decoder |
+| µop Cache | 4K entries, 8-wide | Bypass for hot code |
+| RAT | 180 physical regs | Supports deep OoO |
+| Scheduler | 97 entries | Unified RS |
+| Execution | 6 ports | ALU×2, Load, Store×2, Vector |
+| ROB | 512 entries, 8-wide | In-order retirement |
+| L1-I | 32 KB, 8-way | Instruction cache |
+| L1-D | 48 KB, 12-way | Data cache |
+| L2 | 1.25 MB, 20-way | Unified |
+| DRAM | DDR5-6400, ~80ns | Off-chip |
+
+## When to Use This Pattern
+

+# Electricity Grid: Generation to Consumption
+
+A left-to-right flow diagram showing electricity from multiple generation sources through transmission and distribution networks to end consumers. Demonstrates multi-stage flow layout, voltage level visual hierarchy, and smart grid data overlay.
+
+## Key Patterns Used
+
+- **Multi-stage horizontal flow**: Four distinct columns (Generation → Transmission → Distribution → Consumption)
+- **Stage dividers**: Vertical dashed lines separating each phase
+- **Voltage level hierarchy**: Different line weights/colors for HV, MV, LV
+- **Smart grid data overlay**: Dashed data flow lines from control center
+- **Capacity labels**: Power ratings on generation sources
+- **Multiple source convergence**: Four generators feeding into single transmission grid

+# Feature Film Production Pipeline
+
+A phased workflow showing the five stages of filmmaking, using containers with inner nodes and horizontal sub-flows within a phase.
+
+## Key Patterns Used
+
+- **Phase containers**: Large rounded rectangles with neutral background and dashed borders
+- **Inner task nodes**: Smaller colored nodes inside containers for sub-tasks
+- **Horizontal flow within container**: Post-production shows sequential pipeline with arrows (Editing → Color → VFX → Sound → Score)
+- **Consistent phase spacing**: ~30px gap between phase containers
+- **Phase labels with subtitles**: Each container has title + description

+
+## Layout Notes
+
+- **ViewBox**: 680×780 (standard width, tall for 5 phases)
+- **Container style**: Dashed border (`stroke-dasharray="6 4"`), neutral fill (`var(--bg-secondary)`), `stroke-width="1"`
+- **Container height**: 110px for 3-node phases, 150px for post-production (more complex)
+- **Inner node dimensions**: 160×36px for standard tasks, variable width for post-production sequential flow
+- **Phase gap**: 30px between containers
+- **Horizontal sub-flow**: Post-production uses tightly packed nodes with arrows between them to show sequence
+- **Convergence node**: "Final master / DCP" sits below the horizontal flow, collecting all post outputs

+# Hospital Emergency Department Flow
+
+A multi-path flowchart showing patient journey through an emergency department with priority-based routing using semantic colors (red=critical, amber=urgent, green=stable).
+
+## Key Patterns Used
+
+- **Semantic color coding**: Red/amber/green for priority levels (not arbitrary decoration)
+- **Stage labels**: Left-aligned faded labels marking workflow phases
+- **Convergent paths**: Multiple entry points merging, then branching, then converging again
+- **Nested containers**: Diagnostics grouped in a container with inner nodes
+- **Legend**: Color key at bottom explaining priority levels

+# ML Benchmark Grouped Bar Chart with Dual Axis
+
+A quantitative data visualization comparing LLM inference speed across quantization levels with dual Y-axes, threshold markers, and an inset accuracy table.
+
+## Key Patterns Used
+
+- **Grouped bars**: Min/max range pairs per category using semantic color pairs (lighter=min, darker=max)
+- **Dual Y-axis**: Left axis for primary metric (tok/s), right axis for secondary metric (VRAM GB)
+- **Overlay line graph**: `<polyline>` with labeled dots showing VRAM usage across categories
+- **Threshold marker**: Dashed red horizontal line indicating hardware limit (24 GB GPU)
+- **Zone annotations**: Subtle text labels above/below threshold for context
+- **Inset data table**: Alternating row fills below chart with quantitative accuracy data
+- **Semantic color coding**: Each quantization level gets its own color from the skill palette (red=OOM, amber=slow, teal=sweet spot, blue=fast)
+
+## Diagram Type
+
+This is a **quantitative data chart** with:
+- **Grouped vertical bars**: Range bars showing min–max performance per category
+- **Secondary axis line**: VRAM usage overlaid as a connected scatter plot
+- **Threshold annotation**: Hardware constraint line
+- **Inset table**: Supporting accuracy metrics
+
+## Chart Layout Formula
+
+```
+Chart area:  x=90–590, y=70–410 (500px wide, 340px tall)
+Left Y-axis: Primary metric (tok/s)
+             y = 410 − (val / max_val) × 340
+Right Y-axis: Secondary metric (VRAM GB)
+              Same formula, different scale labels
+Groups:       Divide width by number of categories
+Bars:         Each group → min bar (34px) + 8px gap + max bar (34px)
+Line overlay: <polyline> connecting data points across group centers
+Threshold:    Horizontal dashed line at critical value
+Table:        Below chart, alternating row fills
+```
+
+## Data Mapped
+
+| Quantization | Model Size | Speed (tok/s) | VRAM (GB) | MMLU Pro | Status |
+|-------------|-----------|---------------|-----------|----------|--------|
+| FP16 | 62 GB | 0.5–2 | 62 | 75.2 | OOM / unusable |
+| Q8_0 | 32 GB | 3–5 | 32 | 75.0 | Partial offload |
+| Q4_K_M | 16.8 GB | 8–12 | 16.8 | 73.1 | Fits in VRAM ✓ |
+| IQ3_M | 12 GB | 12–15 | 12 | 70.5 | Full GPU speed |

+# Place Order — UML Sequence Diagram
+
+A UML sequence diagram for the 'Place Order' use case in an e-commerce system. Six lifelines (:Customer, :ShoppingCart, :OrderController, :PaymentGateway, :InventorySystem, :EmailService) interact across 14 numbered messages. An **alt** combined fragment (amber) covers the three conditional outcomes — payment authorized, payment failed, and item unavailable. A **par** combined fragment (teal) nested inside the success branch shows concurrent email confirmation and stock-level update. Demonstrates activation bars, two distinct arrowhead types, UML pentagon fragment tags, and guard conditions.
+
+## Key Patterns Used
+
+- **6 lifelines at equal spacing**: Lifeline centers placed at x=90, 190, 290, 390, 490, 590 (100px apart) so the first box left-edge lands at x=40 and the last right-edge lands at x=640 — exactly filling the safe area
+- **Two-row actor headers**: Each lifeline box shows `":"` (small, tertiary color) on one line and the class name (slightly larger, bold) on a second line, matching the UML anonymous-instance notation `:ClassName`
+- **Two separate arrowhead markers**: `#arr-call` is a filled triangle (`<polygon>`) for synchronous calls; `#arr-ret` is an open chevron (`fill="none"`) for dashed return messages — both use `context-stroke` to inherit line color
+- **Activation bars**: Narrow 8px-wide rectangles (`class="activation"`) layered on top of lifeline stems to show object execution periods; OrderController's bar spans the entire interaction; shorter bars mark PaymentGateway, InventorySystem, and EmailService during their active windows
+- **Combined fragment pentagon tag**: Each `alt` / `par` frame uses a `<polygon>` dog-eared label shape in the top-left corner — points follow the pattern `(x,y) (x+w,y) (x+w+6,y+6) (x+w+6,y+18) (x,y+18)` creating the characteristic UML notch
+- **Nested par inside alt**: The `par` rect (teal) sits inside branch 1 of the `alt` rect (amber); inner rect uses inset x/y (+15/+2) so both borders remain visible and distinguishable
+- **Guard conditions**: Italic text in `[square brackets]` placed immediately after each alt frame divider line, or just inside the top frame for branch 1 — rendered with a dedicated `guard-lbl` class (italic, amber color)
+- **Alt branch dividers**: Solid horizontal lines (`.frag-alt-div`) span the full alt rect width to separate the three branches; par branch separator uses a dashed line (`.frag-par-div`) per UML spec
+- **Lifeline end caps**: Short 14px horizontal tick marks at y=590 (bottom of all lifeline stems) to formally terminate each lifeline
+- **Message sequence annotation**: A faint counter row below the legend (①–③ / ④–⑩ / ⑪–⑫ / ⑬–⑭) explains the four message groups without adding noise to the diagram body

+## Color Assignments
+
+| Element | Color | Reason |
+|---------|-------|--------|
+| Actor header boxes | Neutral (`var(--bg-secondary)`) | Structural / non-semantic — all lifelines share one style |
+| Activation bars | Neutral (`var(--bg-secondary)`) | Show execution periods without adding semantic color |
+| Synchronous call arrows | `var(--text-primary)` + filled triangle | High contrast for calls — the primary interaction direction |
+| Return / dashed arrows | `var(--text-secondary)` + open chevron | Lower contrast for returns — secondary flow direction |
+| `alt` fragment | Amber (`#FAEEDA` / `#854F0B`) | Warning / conditional — matches `c-amber` semantic meaning |
+| Guard condition text | Amber italic | Belongs visually to the alt fragment |
+| `par` fragment | Teal (`#E1F5EE` / `#0F6E56`) | Concurrent success path — matches `c-teal` semantic meaning |
+| Alt branch dividers | Amber solid line | Continuity with the alt frame color |
+| Par branch divider | Teal dashed line | UML spec: par branches separated by dashed lines |
+
+## Layout Notes
+
+- **ViewBox**: 680×648 (standard width; height = lifeline bottom y=590 + legend + annotation + 16px buffer)
+- **Lifeline spacing formula**: `(safe_area_width) / (n_lifelines − 1) = 600 / 5 = 120px` — but use `spacing = 100px` starting at `x=90` so that first box left = 40 and last box right = 640 exactly
+- **Actor box split-label trick**: Two separate `<text>` elements per box — one for `":"` (10px, tertiary color) and one for the class name (11.5px bold, primary color) — avoids the 14px font needing ~150px+ per box for long names like "OrderController"
+- **Pentagon tag formula**: For a fragment starting at `(fx, fy)`, the tag polygon points are `(fx,fy) (fx+w,fy) (fx+w+6,fy+6) (fx+w+6,fy+18) (fx,fy+18)` where `w` = approximate text width of the keyword + 8px padding each side
+- **Nested fragment inset**: The `par` rect uses `x = alt_x + 15` and `y = alt_y_current + 2` so both borders remain simultaneously visible — inset enough to separate visually, not so much that it wastes vertical space
+- **Activation bar placement**: `x = lifeline_cx − 4`, `width = 8` — centered on the lifeline and narrow enough not to obscure the dashed stem behind it
+- **Message label y-offset**: All labels are placed at `y = arrow_y − 5` to sit just above the arrow line; this applies to both left-going and right-going arrows since `text-anchor="middle"` handles horizontal centering automatically
+- **Return arrows entering activation bars**: End `x1/x2` at lifeline center (e.g. x=294 for OrderController) rather than the bar edge (x=286) — the small overlap is intentional and clarifies the target object
+- **Alt guard label placement**: Branch 1 guard goes at `y = frame_top + 13` to the right of the pentagon tag; subsequent branch guards go at `divider_y + 14` so they sit just inside the new branch
+- **Lifeline end cap pattern**: `<line x1="cx−7" y1="590" x2="cx+7" y2="590" stroke-width="1.5"/>` — a simple symmetric tick, no special marker needed

+# Smart City Infrastructure
+
+A multi-system integration diagram showing interconnected city infrastructure (power, water, transport) connected through a central IoT platform with a citizen dashboard on top. Demonstrates hub-spoke layout, diverse physical shapes, and UI mockups.
+
+## Key Patterns Used
+
+- **Hub-spoke layout**: Central IoT platform with radiating data connections to subsystems
+- **Connection dots**: Visual indicators where data lines attach to the central hub
+- **Dashboard/UI mockup**: Screen with mini-charts, gauges, and status indicators
+- **Multi-system integration**: Three independent systems unified by central platform
+- **Semantic line styles**: Different stroke styles for data (dashed), power, water, roads
+- **Physical infrastructure shapes**: Solar panels, wind turbines, dams, pipes, roads, vehicles
+

+## Layout Notes
+
+- **ViewBox**: 720×620 (wider for three-column system layout)
+- **Hub position**: Central IoT at (360, 270) - geometric center
+- **Data lines**: Use quadratic curves or L-shaped paths, add connection dots at hub attachment points
+- **System spacing**: ~200px width per system section
+- **Vertical layers**: Dashboard (top) → IoT Hub (middle) → Systems (bottom)
+- **Component grouping**: Use `<g transform="translate(x,y)">` for each major component for easy positioning

+# Smartphone Layer Anatomy
+
+An exploded view diagram showing all internal layers of a smartphone from front glass to back, with alternating left/right labels to avoid overlap. Demonstrates layered product teardown visualization and component detail.
+
+## Key Patterns Used
+
+- **Exploded vertical stack**: Layers separated vertically to show internal structure
+- **Alternating labels**: Left/right label placement prevents text overlap
+- **Component detail**: Chips, coils, lenses rendered with realistic shapes
+- **Thickness scale**: Measurement indicator on the side
+- **Progressive depth**: Each layer slightly offset to create 3D stack effect
+
+## New Shape Techniques

+## Layout Notes
+
+- **ViewBox**: 800×680 (landscape for mechanism + energy profile)
+- **Mechanism section**: y=60-300, showing reactants → TS → products
+- **Energy profile**: y=320-630, with axes and curve
+- **Atom sizes**: C/O/Br ~12-16px radius, H ~7-8px radius
+- **Bond lengths**: ~25-40px between atom centers
+- **Spacing**: ~140px between mechanism stages
+
+## When to Use This Pattern
+
+Use this diagram style for:
+- Organic reaction mechanisms (SN1, SN2, E1, E2, additions, eliminations)
+- Reaction energy profiles and kinetics
+- Stereochemistry illustrations
+- Enzyme mechanism diagrams
+- Transition state theory visualization
+- Any chemistry concept requiring molecular structures

+# Modern Onshore Wind Turbine Structure
+
+A physical/structural cross-section diagram showing all major components of a modern wind turbine from underground foundation to blade tips.
+
+## Key Patterns Used
+
+- **Underground section**: Soil layers, deep concrete foundation with rebar reinforcement grid, spread footing
+- **Cross-section view**: Tower wall thickness shown, internal components visible
+- **Tapered tower**: Path elements creating realistic tower silhouette that narrows toward top
+- **Internal access**: Ladder with rungs, elevator shaft inside tower
+- **Cable routing**: Power cables running from nacelle down through tower to transformer
+- **Nacelle cutaway**: Gearbox, generator, brake, yaw system all visible inside housing
+- **Rotor assembly**: Hub with pitch motors at blade roots, three composite blades with gradient fill
+- **Ground level marker**: Clear separation between above/below ground
+- **Component color coding**: Each system type has distinct color (blue=generator, gold=gearbox, red=brake, green=yaw, purple=pitch)
+- **Legend bar**: Quick reference for color meanings

+# Dashboard Patterns
+
+Building blocks for UI/dashboard mockups inside a concept diagram — admin panels, monitoring dashboards, control interfaces, status displays.
+
+## Pattern
+
+A "screen" is a rounded dark rect inside a lighter "frame" rect, with chart/gauge/indicator elements nested on top.
+
+```xml
+<!-- Monitor frame -->
+<rect class="dashboard" x="0" y="0" width="200" height="120" rx="8"/>
+<!-- Screen -->
+<rect class="screen" x="10" y="10" width="180" height="85" rx="4"/>
+<!-- Mini bar chart -->
+<rect class="screen-content" x="18" y="18" width="50" height="35" rx="2"/>
+<rect class="screen-chart" x="22" y="38" width="8" height="12"/>
+<rect class="screen-chart" x="33" y="32" width="8" height="18"/>
+<!-- Gauge -->
+<circle class="screen-bar" cx="100" cy="35" r="12"/>
+<text x="100" y="39" text-anchor="middle" fill="#E8E6DE" style="font-size:8px">78%</text>
+<!-- Status indicators -->
+<circle cx="35" cy="74" r="6" fill="#97C459"/> <!-- green = ok -->
+<circle cx="75" cy="74" r="6" fill="#EF9F27"/> <!-- amber = warning -->
+<circle cx="115" cy="74" r="6" fill="#E24B4A"/> <!-- red = alert -->
+```
+
+## CSS
+
+```css
+.dashboard      { fill: #F1EFE8; stroke: #5F5E5A; stroke-width: 1.5; }
+.screen         { fill: #1a1a18; }
+.screen-content { fill: #2C2C2A; }
+.screen-chart   { fill: #5DCAA5; }
+.screen-bar     { fill: #7F77DD; }
+.screen-alert   { fill: #E24B4A; }
+```
+
+## Tips
+
+- Dashboard screens stay dark in both light and dark mode — they represent actual monitor glass.
+- Keep on-screen text small (`font-size:8px` or `10px`) and high-contrast (near-white fill on dark).
+- Use the status triad green/amber/red consistently — OK / warning / alert.
+- A single dashboard usually sits on top of an infrastructure hub diagram as a unified view (see `examples/smart-city-infrastructure.md`).

+# Infrastructure Patterns
+
+Reusable shapes and line styles for infrastructure / systems-integration diagrams (smart cities, IoT networks, industrial systems, multi-domain architectures).
+
+## Layout pattern: hub-spoke
+
+- **Central hub**: Hexagon or circle representing the integration platform
+- **Radiating connections**: Data lines from hub to each subsystem with connection dots
+- **Subsystem sections**: Each system (power, water, transport) in its own region
+- **Dashboard on top**: Optional UI mockup showing a unified view (see `dashboard-patterns.md`)
+
+```xml
+<!-- Central hub (hexagon) -->
+<polygon class="iot-hex" points="0,-45 39,-22 39,22 0,45 -39,22 -39,-22"/>
+
+<!-- Data lines with connection dots -->
+<path class="data-line" d="M 321 248 L 200 248 L 120 380" stroke-dasharray="4 3"/>
+<circle cx="321" cy="248" r="4" fill="#7F77DD"/>
+```
+
+## Semantic line styles
+
+Use a dedicated CSS class per subsystem so every diagram reads the same way:
+
+```css
+.data-line  { stroke: #7F77DD; stroke-width: 2; fill: none; stroke-dasharray: 4 3; }
+.power-line { stroke: #EF9F27; stroke-width: 2; fill: none; }
+.water-pipe { stroke: #378ADD; stroke-width: 4; stroke-linecap: round; fill: none; }
+.road       { stroke: #888780; stroke-width: 8; stroke-linecap: round; fill: none; }
+```
+
+## Power systems
+
+**Solar panel (angled):**
+```xml
+<polygon class="solar-panel" points="0,25 35,8 38,12 3,29"/>
+<line class="solar-frame" x1="12" y1="22" x2="24" y2="13"/>

+<ellipse class="wind-blade" cx="25" cy="5" rx="3" ry="13"/>
+<ellipse class="wind-blade" cx="14" cy="26" rx="3" ry="13" transform="rotate(-120, 25, 18)"/>
+<ellipse class="wind-blade" cx="36" cy="26" rx="3" ry="13" transform="rotate(120, 25, 18)"/>
+```
+
+**Battery with charge level:**
+```xml
+<rect class="battery" x="0" y="0" width="45" height="65" rx="5"/>
+<rect x="10" y="-6" width="10" height="8" rx="2" fill="#27500A"/> <!-- terminal -->
+<rect class="battery-level" x="5" y="12" width="35" height="48" rx="3"/> <!-- fill level -->
+```
+
+**Power pylon:**
+```xml
+<polygon class="pylon" points="30,0 35,0 40,60 25,60"/>
+<line x1="15" y1="10" x2="45" y2="10" stroke="#5F5E5A" stroke-width="3"/>
+<circle cx="18" cy="10" r="3" fill="#FAEEDA" stroke="#854F0B"/> <!-- insulator -->
+```
+
+## Water systems
+
+**Reservoir/dam:**
+```xml
+<polygon class="reservoir-wall" points="0,60 10,0 70,0 80,60"/>
+<polygon class="water" points="12,10 68,10 68,55 75,55 75,58 5,58 5,55 12,55"/>
+<!-- Wave effect -->
+<path d="M 15 25 Q 25 22 35 25 Q 45 28 55 25" fill="none" stroke="#378ADD" opacity="0.5"/>
+```
+
+**Treatment tank:**
+```xml
+<ellipse class="treatment-tank" cx="35" cy="45" rx="30" ry="18"/>
+<rect class="treatment-tank" x="5" y="20" width="60" height="25"/>
+<!-- Bubbles -->

+```
+
+**Pipe with joint and valve:**

+```
+
+## Transport systems

+```
+
+**Traffic light:**

+# Physical Shape Cookbook
+
+Guidance for drawing physical objects (vehicles, buildings, hardware, mechanical systems, anatomy) — when rectangles aren't enough.
+
+## Shape selection
+
+| Physical form | SVG element | Example use |
+|---------------|-------------|-------------|
+| Curved bodies | `<path>` with Q/C curves | Fuselage, tanks, pipes |
+| Tapered/angular shapes | `<polygon>` | Wings, fins, wedges |
+| Cylindrical/round | `<ellipse>`, `<circle>` | Engines, wheels, buttons |
+| Linear structures | `<line>` | Struts, beams, connections |
+| Internal sections | `<rect>` inside parent | Compartments, rooms |
+| Dashed boundaries | `stroke-dasharray` | Hidden parts, fuel tanks |
+
+## Layering approach
+
+1. Draw outer structure first (fuselage, frame, hull)
+2. Add internal sections on top (cabins, compartments)
+3. Add detail elements (engines, wheels, controls)
+4. Add leader lines with labels
+
+## Semantic CSS classes (instead of c-* ramps)
+
+For physical diagrams, define component-specific classes directly rather than applying `c-*` color classes. This makes each part self-documenting and lets you keep a restrained palette:
+
+```css
+.fuselage { fill: #F1EFE8; stroke: #5F5E5A; stroke-width: 1; }
+.wing     { fill: #E6F1FB; stroke: #185FA5; stroke-width: 1; }
+.engine   { fill: #FAECE7; stroke: #993C1D; stroke-width: 1; }
+```
+
+Add these to a local `<style>` inside the SVG (or extend the host page's `<style>` block). The light-mode/dark-mode pattern still works — use the CSS variables from the template (`var(--bg-secondary)`, `var(--border)`, `var(--text-primary)`) if you want dark-mode awareness.
+
+## Reference examples
+
+Look at these example files for working physical-diagram patterns:
+
+- `examples/commercial-aircraft-structure.md` — fuselage curves + tapered wings + ellipse engines
+- `examples/wind-turbine-structure.md` — underground foundation, tubular tower, nacelle cutaway
+- `examples/smartphone-layer-anatomy.md` — exploded-view stack with alternating labels
+- `examples/apartment-floor-plan-conversion.md` — walls, doors, windows, proposed changes

 # Architecture Diagram Skill
 
 Generate professional, dark-themed technical architecture diagrams as standalone HTML files with inline SVG graphics. No external tools, no API keys, no rendering libraries — just write the HTML file and open it in a browser.
 
+## Scope
+
+**Best suited for:**
+- Software system architecture (frontend / backend / database layers)
+- Cloud infrastructure (VPC, regions, subnets, managed services)
+- Microservice / service-mesh topology
+- Database + API map, deployment diagrams
+- Anything with a tech-infra subject that fits a dark, grid-backed aesthetic
+
+**Look elsewhere first for:**
+- Physics, chemistry, math, biology, or other scientific subjects
+- Physical objects (vehicles, hardware, anatomy, cross-sections)
+- Floor plans, narrative journeys, educational / textbook-style visuals
+- Hand-drawn whiteboard sketches (consider `excalidraw`)
+- Animated explainers (consider an animation skill)
+
+If a more specialized skill is available for the subject, prefer that. If none fits, this skill can also serve as a general SVG diagram fallback — the output will just carry the dark tech aesthetic described below.

+4. **No HERMES_SESSION_* inheritance** — the agent's current gateway
+   session must not leak into tests.

+"""Tests for Discord attachment downloads via the authenticated bot session.

+Covers the three download paths (image / audio / document) in
+``DiscordAdapter._handle_message()`` and the shared ``_cache_discord_*``
+helpers. Verifies that:
+
+- ``att.read()`` is preferred over the legacy URL-based downloaders so
+  that Discord's CDN auth (and user-environment DNS quirks) can't block
+  media caching. (issues #8242 image 403s, #6587 CDN SSRF false-positives)
+- Falls back cleanly to the SSRF-gated ``cache_*_from_url`` helpers
+  (image/audio) or SSRF-gated aiohttp (documents) when ``att.read()``
+  isn't available or fails.
+- The document fallback path now runs through the SSRF gate for
+  defense-in-depth. (issue #11345)
