chore: release v0.16.0

fix(ci): anchor coverage/ gitignore rule to repo root (#591 )
coverage/ matched tests/fixtures/llm_traces/coverage/, causing release-plz to detect committed+ignored files and abort on every push to main. PR #561 has been stuck with only 1 changelog entry since v0.15.0. Anchor the rule to the repo root with /coverage/ so it only ignores the top-level coverage report directory generated by cargo llvm-cov, not nested fixture directories. [skip-regression-check]

+# Smart Model Routing for IronClaw
+
+**Status:** Implemented
+**Author:** Microwave
+**Date:** 2026-02-19
+
+## What
+
+Automatic model selection based on request complexity. The router analyzes each user message and selects an appropriate model tier (flash/standard/pro/frontier), then maps that tier to a configured model.
+
+## Why
+
+1. **Cost optimization** — Simple requests ("hi", "what time is it") don't need expensive models
+2. **User experience** — Simple requests return faster with lightweight models
+3. **NEAR AI native** — Default backend uses NEAR AI inference where costs vary by model
+4. **Zero-config value** — Users benefit immediately without configuration
+5. **Not just power users** — Everyone gets smart defaults, power users can override
+
+## How
+
+### Architecture

+
+### Complexity Scorer (13 Dimensions)
+
+Each dimension produces a 0-100 score. Weighted sum determines total.
+
+| Dimension | Weight | Signals |
+|-----------|--------|---------|
+| Reasoning Words | 14% | "why", "explain", "compare", "trade-offs" |
+| Token Estimate | 12% | Prompt length |
+| Code Indicators | 10% | Backticks, syntax, "implement", "PR" |
+| Multi-Step | 10% | "first", "then", "after", "steps" |
+| Domain Specific | 10% | Technical terms (configurable) |
+| Creativity | 7% | "write", "summarize", "tweet", "blog" |
+| Question Complexity | 7% | Multiple questions, open-ended starters |
+| Precision | 6% | Numbers, "exactly", "calculate" |
+| Ambiguity | 5% | Vague references |
+| Context Dependency | 5% | "previous", "you said" |
+| Sentence Complexity | 5% | Commas, conjunctions, clause depth |
+| Tool Likelihood | 5% | "read", "deploy", "install" |
+| Safety Sensitivity | 4% | "password", "auth", "vulnerability" |
+
+**Multi-dimensional boost:** +30% when 3+ dimensions score above threshold.
+
+### Tier Boundaries
+
+| Score | Tier | Typical Use Case |
+|-------|------|------------------|
+| 0-15 | flash | Greetings, acknowledgments, quick lookups |
+| 16-40 | standard | Writing, comparisons, defined tasks |
+| 41-65 | pro | Multi-step analysis, code review |
+| 66+ | frontier | Critical decisions, security audits |
+
+### Pattern Overrides
+
+Fast-path rules that bypass scoring for obvious cases:
+
+```yaml
+# Force flash tier
+- "^(hi|hello|hey|thanks|ok|sure|yes|no)$"
+- "^what.*(time|date|day)"
+
+# Force frontier tier
+- "security.*(audit|review|scan)"
+- "vulnerabilit(y|ies).*(review|scan|check|audit)"
+
+# Force pro tier
+- "deploy.*(mainnet|production)"
+```
+
+### Configuration
+
+> **Note:** The current implementation supports smart routing via
+> `NEARAI_CHEAP_MODEL` and `SMART_ROUTING_CASCADE` env vars, plus
+> `domain_keywords` on `SmartRoutingConfig`. The full `llm.routing` YAML
+> schema below is the target design — not all knobs are wired yet.
+
+**Default (zero-config):**
+```yaml
+llm:
+  routing:
+    enabled: true  # default
+```
+
+**Power user overrides (target schema):**
+```yaml
+llm:
+  routing:
+    enabled: true
+    tiers:
+      flash: "claude-3-5-haiku-latest"
+      standard: "claude-sonnet-4-5-latest"
+      pro: "claude-sonnet-4-5-latest"
+      frontier: "claude-opus-4-5-latest"
+    thinking:
+      pro: "low"
+      frontier: "medium"
+    overrides:
+      - pattern: "my-custom-pattern"
+        tier: "pro"
+    domain_keywords:  # Custom keywords for your domain
+      - "mycompany"
+      - "myproduct"
+      - "internal-tool"
+```
+
+If `domain_keywords` is not set, uses `DEFAULT_DOMAIN_KEYWORDS` which covers common web3/infra terms.
+
+**Disable routing (pin model):**
+```yaml
+llm:
+  routing:
+    enabled: false
+  model: "claude-opus-4-5"
+```
+
+**Bring your own keys:**
+```yaml
+llm:
+  backend: anthropic
+  api_key: "sk-..."
+  routing:
+    enabled: true  # still works with external providers
+```
+
+### Integration Points
+
+1. **RoutingProvider** — New wrapper implementing `LlmProvider` trait (like `FailoverProvider`)
+2. **Scorer** — Pure function, no I/O, fast (~1ms)
+3. **Config schema** — Extend `LlmConfig` with `routing` section
+4. **Telemetry** — Log routing decisions for observability
+
+### Model Agnosticism
+
+**Critical:** No hardcoded model names in the router logic itself.
+
+- Tier→model mappings come from config
+- Default mappings use `-latest` patterns where supported
+- NEAR AI backend handles actual model resolution
+- Router only knows about tiers
+
+### Layers of Control
+
+| Layer | User Type | Config |
+|-------|-----------|--------|
+| 1. Zero-config | Everyone | `routing.enabled: true` (default) |
+| 2. Tier tuning | Power users | Custom `routing.tiers` mapping |
+| 3. Pattern overrides | Power users | Custom `routing.overrides` |
+| 4. Model pinning | Power users | `routing.enabled: false` + `model: X` |
+| 5. Own API keys | Power users | `backend: anthropic` + `api_key` |
+
+## Implementation Plan
+
+1. [x] Port scorer to Rust (`src/llm/smart_routing.rs`)
+2. [x] Implement router wrapper (`src/llm/smart_routing.rs`)
+3. [x] Extend config schema (`src/config.rs`)
+4. [x] Wire into provider creation (`src/llm/mod.rs`)
+5. [x] Add telemetry/logging
+6. [x] Tests with real conversation samples
+7. [x] Codex + Gemini security review
+8. [x] Documentation updated (this spec)
+
+## Expected Outcomes
+
+- **50-70% cost reduction** for typical usage patterns
+- **Faster responses** for simple requests
+- **Zero config required** for default benefits
+- **Full control** for power users who want it

+
+# Local Testing with Docker + Chrome MCP
+
+Use this skill to build, run, and test IronClaw web gateway changes locally using `Dockerfile.test` and Chrome MCP browser automation tools.
+
+## Quick Start
+
+```bash
+# Build the test image (libsql-only, no PostgreSQL needed)
+docker build --platform linux/amd64 -f Dockerfile.test -t ironclaw-test .
+
+# Run on port 3003 (default)
+docker run --rm -p 3003:3003 \
+  -e ONBOARD_COMPLETED=true \
+  -e CLI_ENABLED=false \
+  -e NEARAI_API_KEY=<key> \
+  ironclaw-test
+
+# Open in browser
+# http://localhost:3003/?token=test
+```
+
+## Building the Image
+
+The test Dockerfile uses a two-stage build: Rust compilation with `--features libsql` (no PostgreSQL dependency), then a minimal Debian runtime image.
+
+```bash
+docker build --platform linux/amd64 -f Dockerfile.test -t ironclaw-test .
+```
+
+Build takes ~5-10 minutes on first run (cached subsequent builds are faster). The `--platform linux/amd64` flag avoids QEMU warnings on Apple Silicon but can be omitted if targeting native architecture.
+
+## Running Containers
+
+### Required Environment Variables
+
+| Variable | Purpose | Default in Dockerfile |
+|----------|---------|----------------------|
+| `ONBOARD_COMPLETED=true` | Skip onboarding wizard (exits immediately otherwise) | not set |
+| `CLI_ENABLED=false` | Disable TUI/REPL (causes EOF shutdown otherwise) | not set |
+
+### LLM Backend Configuration
+
+Pick ONE of these configurations:
+
+**NEAR AI (API key mode):**
+```bash
+docker run --rm -p 3003:3003 \
+  -e ONBOARD_COMPLETED=true \
+  -e CLI_ENABLED=false \
+  -e NEARAI_API_KEY=<your-key> \
+  ironclaw-test
+```
+
+**NEAR AI (session token mode):**
+```bash
+docker run --rm -p 3003:3003 \
+  -e ONBOARD_COMPLETED=true \
+  -e CLI_ENABLED=false \
+  -e NEARAI_SESSION_TOKEN=<sess_xxx> \
+  -e NEARAI_BASE_URL=https://private.near.ai \
+  ironclaw-test
+```
+
+**OpenAI:**
+```bash
+docker run --rm -p 3003:3003 \
+  -e ONBOARD_COMPLETED=true \
+  -e CLI_ENABLED=false \
+  -e LLM_BACKEND=openai \
+  -e OPENAI_API_KEY=<your-key> \
+  ironclaw-test
+```
+
+**Anthropic:**
+```bash
+docker run --rm -p 3003:3003 \
+  -e ONBOARD_COMPLETED=true \
+  -e CLI_ENABLED=false \
+  -e LLM_BACKEND=anthropic \
+  -e ANTHROPIC_API_KEY=<your-key> \
+  ironclaw-test
+```
+
+**Dummy run (no LLM, just test the UI loads):**
+```bash
+docker run --rm -p 3003:3003 \
+  -e ONBOARD_COMPLETED=true \
+  -e CLI_ENABLED=false \
+  -e NEARAI_API_KEY=dummy \
+  ironclaw-test
+```
+
+### Common Overrides
+
+| Variable | Purpose | Example |
+|----------|---------|---------|
+| `GATEWAY_PORT` | Change the listen port | `3003` (default) |
+| `GATEWAY_AUTH_TOKEN` | Auth token for API | `test` (default) |
+| `NEARAI_MODEL` | Override LLM model | `claude-3-5-sonnet-20241022` |
+| `RUST_LOG` | Logging verbosity | `ironclaw=debug` |
+| `ROUTINES_ENABLED` | Enable routines | `true`/`false` |
+| `SKILLS_ENABLED` | Enable skills system | `true` (default) |
+
+### Multi-Instance Testing
+
+Run multiple containers on different host ports:
+
+```bash
+docker run --rm -d --name ic-test-a -p 3003:3003 -e ONBOARD_COMPLETED=true -e CLI_ENABLED=false -e NEARAI_API_KEY=dummy ironclaw-test
+docker run --rm -d --name ic-test-b -p 3004:3003 -e ONBOARD_COMPLETED=true -e CLI_ENABLED=false -e NEARAI_API_KEY=dummy ironclaw-test
+```
+
+## Chrome MCP Testing Workflow
+
+Use the Claude for Chrome browser automation tools to test the web UI.
+
+### Step 1: Get Browser Context
+
+```
+mcp__claude-in-chrome__tabs_context_mcp
+```
+
+Always start here to see current tabs and get fresh tab IDs.
+
+### Step 2: Open the Gateway
+
+```
+mcp__claude-in-chrome__tabs_create_mcp  url=http://localhost:3003/?token=test
+```
+
+### Step 3: Verify the Page
+
+```
+mcp__claude-in-chrome__read_page
+```
+
+Check for:
+- "Connected" indicator in top-right
+- All tabs visible: Chat, Memory, Jobs, Routines, Extensions, Skills
+
+### Step 4: Take Screenshots
+
+```
+mcp__claude-in-chrome__computer  action=screenshot
+```
+
+### Step 5: Test Mobile Viewport
+
+```
+mcp__claude-in-chrome__resize_window  width=375  height=812
+mcp__claude-in-chrome__computer  action=screenshot
+```
+
+Reset to desktop:
+```
+mcp__claude-in-chrome__resize_window  width=1280  height=800
+```
+
+### Step 6: Run JavaScript Checks
+
+```
+mcp__claude-in-chrome__javascript_tool  script="document.querySelector('.connection-status')?.textContent"
+```
+
+### Step 7: Test Interactions
+
+Click tabs, send messages, search skills — use `computer` tool with `action=click` and coordinate-based clicks, or use `find` + `form_input` for text entry.
+
+## Cleanup
+
+```bash
+# Stop a specific container
+docker stop ic-test-a
+
+# Stop all test containers
+docker ps --filter ancestor=ironclaw-test -q | xargs -r docker stop
+
+# Remove the test image
+docker rmi ironclaw-test
+```
+
+## Troubleshooting
+
+### Container exits immediately
+- **Missing `ONBOARD_COMPLETED=true`**: The onboarding wizard tries to read stdin, gets EOF, and exits.
+- **Missing `CLI_ENABLED=false`**: The REPL channel reads stdin, gets EOF, and shuts down the agent.
+
+### "Model not found" or LLM errors
+- Check that your API key/token is valid and the model name is correct.
+- For NEAR AI session token mode, you also need `NEARAI_BASE_URL=https://private.near.ai`.
+
+### Platform mismatch warnings on Apple Silicon
+- The `--platform linux/amd64` flag causes QEMU emulation warnings — these are harmless.
+- Alternatively, omit the flag and build natively if your dependencies support ARM64.
+
+### Port already in use
+- The dev server defaults to port 3001; the test Dockerfile defaults to 3003 to avoid conflicts.
+- Use a different host port: `-p 3005:3003`.
+
+### Cannot connect from browser
+- Verify `GATEWAY_HOST=0.0.0.0` (set by default in Dockerfile).
+- Check the container logs: `docker logs <container-id>`.
+- Make sure you include the token query param: `?token=test`.

+//! Wraps any [`LlmProvider`] and captures every LLM interaction into

+//! testing. Recorded traces can be replayed later via `TraceLlm`.
+//!
+//! The trace includes:
+//! - **Memory snapshot**: workspace documents captured before the first LLM call
+//! - **HTTP exchanges**: all outgoing HTTP request/response pairs from tools
+//! - **Steps**: user inputs, LLM responses (text/tool_calls), and expected tool
+//!   results for verifying tool output during replay
+//!
+//! Enable by setting `IRONCLAW_RECORD_TRACE=1` at runtime.

+//! Restart tool for graceful process restart.
+//!
+//! ## Architecture
+//!
+//! IronClaw runs inside a Docker container with an entrypoint loop that monitors exit codes:
+//! - **Exit code 0** (clean): Reset failure counter, wait `IRONCLAW_RESTART_DELAY` (default 5s), restart
+//! - **Exit code ≠ 0** (failure): Increment failure counter, exit after `IRONCLAW_MAX_FAILURES` (default 10)
+//!
+//! This tool triggers a restart by calling `std::process::exit(0)` after a brief delay, allowing
+//! the HTTP response to be flushed before the process terminates. The entrypoint loop then
+//! detects the clean exit and automatically restarts the process.
+//!
+//! ## Security
+//!
+//! - **Approval Model:** User approval happens at the command level via web modal confirmation,
+//!   not at tool execution level. This allows approved commands to execute in autonomous jobs.
+//! - **Web-Only Access:** The `/restart` command only works via the web gateway (enforced in commands.rs)
+//! - **Parameter Validation:** Delay clamped to 1-30 seconds
+//!
+//! ## Known Limitations
+//!
+//! - Hard exit without graceful shutdown (no destructor cleanup, no RwLock drains)
+//! - In-flight jobs are paused during restart and resumed by the entrypoint
+//! - Future: Implement graceful shutdown with CancellationToken for proper resource cleanup

-//! - GET-only, no custom headers or body
-//! - Always attempts HTML → Markdown conversion via Readability
-//! - Returns structured output: `{url, final_url, status, title, content, word_count}`
-//! - Auto-approved (no confirmation prompt)
-//! - Follows up to 3 redirects, SSRF-validating each hop
-//!
-//! All the same security infrastructure as `http`:
-//! HTTPS-only, SSRF protection, DNS rebinding defence, outbound/inbound leak
-//! scanning, 5 MB response cap.
