Add message journal, graceful restart, and clean repo for public release

Three workstreams implemented:

W1 (Repo Split): Remove proprietary BloxServer files and docs, update
pyproject.toml URLs to public GitHub, clean doc references, add CI
workflow (.github/workflows/ci.yml) and CONTRIBUTING.md.

W2 (Message Journal): Add DispatchHook protocol for dispatch lifecycle
events, SQLite-backed MessageJournal with WAL mode for certified-mail
delivery guarantees (PENDING→DISPATCHED→ACKED/FAILED), integrate hooks
into StreamPump._dispatch_to_handlers(), add journal REST endpoints,
and aiosqlite dependency.

W3 (Hot Deployment): Add RestartOrchestrator for graceful restart with
queue drain and journal stats collection, SIGHUP signal handler in CLI,
POST /organism/restart endpoint, restart-aware app lifespan with journal
recovery on boot, and os.execv/subprocess re-exec for Unix/Windows.

All 439 tests pass (37 new tests for W2/W3).

+# Contributing to xml-pipeline
+
+Thank you for considering contributing to xml-pipeline.
+
+## Development Setup
+
+```bash
+git clone https://github.com/xml-pipeline/xml-pipeline.git
+cd xml-pipeline
+python -m venv .venv
+source .venv/bin/activate  # Linux/macOS
+# .venv\Scripts\activate   # Windows
+
+pip install -e ".[dev]"
+```
+
+## Running Tests
+
+```bash
+pytest tests/ -v
+```
+
+Skip slow/integration tests:
+
+```bash
+pytest tests/ -v -m "not slow"
+```
+
+## Code Style
+
+This project uses **ruff** for linting and formatting, **mypy** for type checking.
+
+```bash
+ruff check xml_pipeline/ tests/
+ruff format xml_pipeline/ tests/
+mypy xml_pipeline/
+```
+
+All functions must have type hints. Async handlers use `async def`.
+
+## Pull Request Process
+
+1. Fork the repo and create a feature branch from `main`.
+2. Write tests for new functionality in `tests/`.
+3. Ensure `pytest`, `ruff check`, and `mypy` pass.
+4. Keep commits focused and write clear commit messages.
+5. Open a PR against `main` with a description of what changed and why.
+
+## Architecture
+
+Read `CLAUDE.md` for the full architecture overview. Key principles:
+
+- **XML is the sovereign wire format** -- all messages are validated XML envelopes.
+- **Handlers are untrusted** -- the pump enforces identity, routing, and thread isolation.
+- **Pipeline steps are composable** -- add new processing stages by inserting async functions.
+- **Async-first** -- everything is `async def`, powered by aiostream.
+
+## Adding a New Pipeline Step
+
+1. Create `xml_pipeline/message_bus/steps/your_step.py`.
+2. Implement `async def your_step(state: MessageState) -> MessageState`.
+3. Insert into the pipeline in `stream_pump.py` `build_pipeline()`.
+4. Add tests in `tests/test_pipeline_steps.py`.
+
+## Adding a New Handler
+
+1. Define a `@xmlify @dataclass` payload in your handler module.
+2. Write an `async def handle_*(payload, metadata) -> HandlerResponse | None`.
+3. Register in `organism.yaml` under `listeners`.
+4. See `docs/handler-contract-v2.1.md` for the full contract.

-
-### Stripe Configuration
-
-```python
-# One-time setup (or via Stripe Dashboard)
-
-# Free tier product
-free_product = stripe.Product.create(
-    name="BloxServer Free",
-    description="Build AI agent swarms, visually",

-
-# Pro tier product
-pro_product = stripe.Product.create(
-    name="BloxServer Pro",
-    description="Unlimited workflows, marketplace access, custom WASM",
-)
-
-pro_base_price = stripe.Price.create(

-## Database Schema
-
-```sql
--- Users table (synced from Clerk + Stripe)
-CREATE TABLE users (
-    id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
-    clerk_id VARCHAR(255) UNIQUE NOT NULL,

-
--- Usage tracking (local, for dashboard + Stripe sync)
-CREATE TABLE usage_records (

-
--- Stripe webhook events (idempotency)
-CREATE TABLE stripe_events (

-
--- Index for cleanup
-CREATE INDEX idx_stripe_events_processed ON stripe_events(processed_at);

-
-## Usage Tracking
-
-### Real-Time Counting (Redis)
-
-```python
-# On every workflow execution
-async def record_workflow_run(user_id: str):
-    """Increment run counter in Redis."""
-    key = f"usage:{user_id}:runs:{get_current_period()}"

-
-    # Track users with usage for batch sync
-    await redis.sadd("users:with_usage", user_id)
-
-async def record_llm_tokens(user_id: str, tokens_in: int, tokens_out: int):

-    await redis.incrby(f"usage:{user_id}:tokens_in:{period}", tokens_in)
-    await redis.incrby(f"usage:{user_id}:tokens_out:{period}", tokens_out)
-```
-
-### Periodic Sync to Stripe (Hourly)
-
-```python
-async def sync_usage_to_stripe():

-
-    # Clear the tracking set (will rebuild next hour)
-    await redis.delete("users:with_usage")
-```
-
-### Dashboard Query
-
-```python
-async def get_usage_dashboard(user_id: str) -> UsageDashboard:

-
-    tier_limit = get_tier_runs_limit(user.tier)
-
-    return UsageDashboard(
-        period_start=period,
-        period_end=user.current_period_end,
-
-        runs_used=runs,

-
-## Customer Portal
-
-Stripe's hosted portal for self-service billing management.
-
-```python
-async def get_customer_portal_url(user: User) -> str:
-    """Generate a portal session URL for the user."""
-    session = await stripe.billing_portal.Session.create(

-        return_url="https://app.openblox.ai/settings/billing"
-    )
-    return session.url
-```
-
-**Portal capabilities:**
-- Update payment method
-- View invoices and receipts
-- Cancel subscription
-- Upgrade/downgrade plan (if configured)
-
-## Email Templates
-
-| Trigger | Template | Content |
-|---------|----------|---------|
-| Trial started | `trial_started` | Welcome, trial ends on X |
-| Trial ending (3 days) | `trial_ending` | Your trial ends soon, card will be charged |
-| Trial converted | `trial_converted` | Welcome to Pro! |
-| Payment succeeded | `payment_succeeded` | Receipt attached |
-| Payment failed (1st) | `payment_failed_soft` | Please update your card |
-| Payment failed (2nd) | `payment_failed_warning` | Service will be interrupted |
-| Payment failed (final) | `downgraded_payment_failed` | You've been downgraded |
-| Subscription canceled | `subscription_canceled` | Access until period end |
-| Downgraded | `downgraded_to_free` | You're now on Free |
-
-## Rate Limiting & Abuse Prevention
-
-### Soft Limits (Warning)
-
-```python
-async def check_usage_limits(user_id: str) -> UsageLimitResult:
-    """Check if user is approaching limits."""
-    usage = await get_current_usage(user_id)
-    user = await get_user(user_id)
-    tier_limit = get_tier_runs_limit(user.tier)
-
-    percentage = (usage.runs / tier_limit) * 100
-
-    if percentage >= 100:
-        return UsageLimitResult(
-            allowed=True,  # Still allow, but warn
-            warning="You've exceeded your included runs. Overage charges apply.",
-            overage_rate="$0.50 per 1,000 runs"
-        )
-    elif percentage >= 80:
-        return UsageLimitResult(
-            allowed=True,
-            warning=f"You've used {percentage:.0f}% of your monthly runs."
-        )
-
-    return UsageLimitResult(allowed=True)
-```
-
-### Hard Limits (Free Tier)
-
-```python
-async def enforce_free_tier_limits(user_id: str) -> bool:
-    """Free tier has hard limits - no overage allowed."""
-    user = await get_user(user_id)
-    if user.tier != "free":
-        return True  # Paid tiers have soft limits
-
-    usage = await get_current_usage(user_id)
-    if usage.runs >= 1000:
-        raise UsageLimitExceeded(
-            "You've reached the Free tier limit of 1,000 runs/month. "
-            "Upgrade to Pro for unlimited workflows."
-        )
-
-    return True
-```
-
-## Testing
-
-### Test Mode
-
-Stripe provides test mode with test API keys and test card numbers.
-
-```python
-# .env
-STRIPE_SECRET_KEY=sk_test_...  # Test mode
-STRIPE_WEBHOOK_SECRET=whsec_...
-
-# Test cards
-# 4242424242424242 - Succeeds
-# 4000000000000002 - Declined
-# 4000002500003155 - Requires 3D Secure
-```
-
-### Webhook Testing
-
-```bash
-# Use Stripe CLI to forward webhooks locally
-stripe listen --forward-to localhost:8000/webhooks/stripe
-
-# Trigger test events
-stripe trigger invoice.payment_succeeded
-stripe trigger customer.subscription.trial_will_end
-```
-
-## Monitoring & Alerts
-
-| Metric | Alert Threshold |
-|--------|-----------------|
-| Webhook processing time | > 5 seconds |
-| Webhook failure rate | > 1% |
-| Payment failure rate | > 5% |
-| Usage sync lag | > 2 hours |
-| Stripe API errors | Any 5xx |
-
-## Security Checklist
-
-- [ ] Webhook signature verification
-- [ ] Idempotent event processing
-- [ ] API keys in environment variables (never in code)
-- [ ] Customer portal for sensitive operations (not custom UI)
-- [ ] PCI compliance via Stripe Checkout (no card data touches our servers)
-- [ ] Audit log for billing events

-# BloxServer LLM Abstraction Layer — Resilient Multi-Provider Architecture
-
-**Status:** Design
-**Date:** January 2026
-
-## Overview
-
-The LLM abstraction layer is the critical path for all AI operations in BloxServer. It must handle:
-
-- **Viral growth**: 100 → 10,000 users overnight
-- **Provider outages**: Single provider down ≠ platform down
-- **Fair access**: Paid users prioritized, free users served fairly
-- **Cost control**: Platform keys vs BYOK (Bring Your Own Key)
-- **Low latency**: Sub-second for simple calls, reasonable for complex
-
-This document specifies the defense-in-depth architecture that survives success.

-    """Check if user can make this request."""
-
-    # BYOK users bypass platform limits
-    if user.has_own_api_key(request.provider):

-
-### Rate Limit Headers
-
-Return standard headers so clients can self-regulate:
-
-```python
-def rate_limit_headers(user: User) -> dict:
-    limits = TIER_LIMITS[user.tier]
-    current = await get_current_usage(user.id)
-
-    return {
-        "X-RateLimit-Limit": str(limits.requests_per_minute),
-        "X-RateLimit-Remaining": str(max(0, limits.requests_per_minute - current.rpm)),
-        "X-RateLimit-Reset": str(int(time.time()) + 60),
-    }
-```
-
-## Layer 2: Semantic Cache
-
-Identical requests return cached responses. Reduces load and cost.
-
-### Cache Key Generation
-
-```python
-import hashlib
-import json
-
-def hash_request(request: LLMRequest) -> str:
-    """Generate deterministic cache key for request."""
-
-    # Include all parameters that affect output
-    cache_input = {
-        "model": request.model,
-        "messages": [
-            {"role": m.role, "content": m.content}
-            for m in request.messages
-        ],
-        "temperature": request.temperature,
-        "max_tokens": request.max_tokens,
-        "tools": request.tools,  # Tool definitions matter
-        # Exclude: user_id, timestamps, request_id
-    }
-
-    serialized = json.dumps(cache_input, sort_keys=True)
-    return hashlib.sha256(serialized.encode()).hexdigest()[:32]
-```
-
-### Cache Logic
-
-```python
-@dataclass
-class CachedResponse:
-    response: LLMResponse
-    cached_at: float
-    hit_count: int
-
-async def check_semantic_cache(request: LLMRequest) -> LLMResponse | None:
-    """Check if we've seen this exact request before."""
-
-    cache_key = f"llmcache:{hash_request(request)}"

-        await redis.hincrby(f"llmcache:stats", "hits", 1)
-
-        return LLMResponse(

-            model=data["model"],
-            usage=data["usage"],
-            cached=True,
-        )
-
-    await redis.hincrby(f"llmcache:stats", "misses", 1)
-    return None
-
-async def cache_response(request: LLMRequest, response: LLMResponse):
-    """Cache response with TTL based on determinism."""
-
-    # Don't cache errors or empty responses
-    if response.error or not response.content:
-        return
-
-    cache_key = f"llmcache:{hash_request(request)}"
-
-    # TTL based on temperature (determinism)
-    if request.temperature == 0:
-        ttl = 86400  # 24 hours for deterministic
-    elif request.temperature < 0.3:
-        ttl = 3600   # 1 hour
-    elif request.temperature < 0.7:
-        ttl = 300    # 5 minutes
-    else:
-        return       # Don't cache high-temperature responses
-
-    cache_data = {
-        "content": response.content,

-        "usage": response.usage,
-        "cached_at": time.time(),
-    }
-
-    await redis.setex(cache_key, ttl, json.dumps(cache_data))
-```
-
-### Expected Cache Performance
-
-| Use Case | Temperature | Expected Hit Rate |
-|----------|-------------|-------------------|
-| Tool calls (same inputs) | 0 | 70-90% |
-| Structured extraction | 0-0.3 | 50-70% |
-| Agent reasoning | 0.5-0.7 | 20-40% |
-| Creative content | 0.8-1.0 | ~0% |
-
-**Aggregate impact:** 30-40% reduction in API calls for typical workloads.
-
-## Layer 3: Priority Queues
-
-Paid users get priority. Free users are served fairly but can be shed under load.
-
-### Queue Structure
-
-```python
-# Redis sorted set with composite score
-# Score = (priority * 1B) + timestamp
-# Lower score = higher priority + earlier arrival
-
-QUEUE_PRIORITIES = {

-    Tier.ENTERPRISE: 1,
-    Tier.PRO: 2,

-## Viral Day Playbook
-
-What to do when that tweet hits:
-
-### Hour 0-1: Detection
-- Alert: Queue depth > 500
-- Action: Monitor, no intervention needed
-
-### Hour 1-2: Escalation
-- Alert: Queue depth > 1000, latency spiking
-- Action:
-  - Verify all provider circuits are healthy
-  - Check cache hit rate (should be climbing)
-  - Prepare to enable aggressive load shedding
-
-### Hour 2-4: Peak
-- Alert: Queue depth > 2000, free tier rejections > 30%
-- Action:
-  - Enable aggressive load shedding for free tier
-  - Send "high demand" email to free users with upgrade CTA
-  - Monitor Pro/Enterprise latency (must stay < 30s)
-  - Tweet acknowledgment: "We're experiencing high demand due to [reason]. Pro users unaffected."
-
-### Hour 4-8: Stabilization
-- Queue draining as cache warms and load shedding works
-- Many users convert to Pro or add BYOK keys
-- Circuits recovering as providers stabilize
-
-### Post-Mortem
-- Review metrics: peak queue, rejection rate, conversion rate
-- Adjust tier limits if needed
-- Consider adding provider capacity for sustained growth

-# Premium Librarian — RLM-Powered Codebase Intelligence
-
-**Status:** Design Spec  
-**Author:** Dan & Donna  
-**Date:** 2026-01-26
-
-## Overview
-
-The Premium Librarian is an RLM-powered (Recursive Language Model) tool that can ingest entire codebases or document corpora — millions of tokens — and answer natural language queries about them.
-
-Unlike traditional code search (grep, ripgrep, Sourcegraph), the Premium Librarian *understands* structure, relationships, and intent. It can answer questions like:
-
-- "Where are edges calculated in OpenCASCADE?"
-- "How does the authentication flow work?"
-- "What would break if I changed this interface?"

-## Chunkers
-
-The RLM algorithm needs content-aware chunking. Different content types have different natural boundaries.
-
-### Built-in Chunkers
-
-| Chunker | Content Types | Chunking Strategy |
-|---------|---------------|-------------------|
-| **Code** | .py, .js, .ts, .cpp, .c, .java, .go, .rs, etc. | Functions, classes, modules. Preserves imports, docstrings, signatures. |
-| **Prose** | .md, .txt, .rst, .adoc | Paragraphs, sections, chapters. Preserves headings, structure. |
-| **Structured** | .yaml, .json, .xml, .toml, .ini | Schema-aware. Preserves hierarchy, keys, nesting. |
-| **Tabular** | .csv, .tsv, .parquet | Row groups with headers. Preserves column semantics. |
-
-### Content Type Detection
-
-1. File extension mapping (fast path)
-2. MIME type detection
-3. Content sniffing (magic bytes, heuristics)
-4. User override via config
-
-### Custom WASM Chunkers
-
-For specialized formats, users can provide their own chunker:
-
-```typescript
-// chunker.ts (AssemblyScript)
-import { Chunk, ChunkMetadata } from "@openblox/chunker-sdk";
-
-export function chunk(content: string, metadata: ChunkMetadata): Chunk[] {
-  // Custom logic for proprietary format
-  const chunks: Chunk[] = [];
-  
-  // Parse your format, emit chunks
-  // Each chunk has: content, startLine, endLine, type, name
-  
-  return chunks;
-}
-```
-
-**Compile & upload:**
-```bash
-asc chunker.ts -o chunker.wasm
-# Upload via API or CLI
-```
-
-**Security:**
-- WASM runs sandboxed (can't escape, can't access filesystem)
-- CPU/memory limits enforced
-- Chunker is pure function: string in, chunks out
-
-## Ingest Pipeline
-
-### 1. Upload
-
-```
-POST /api/v1/libraries
-{
-  "name": "opencascade",
-  "source": {
-    "type": "git",
-    "url": "https://github.com/Open-Cascade-SAS/OCCT.git",
-    "branch": "master"
-  },
-  // OR
-  "source": {
-    "type": "upload",
-    "archive": "<base64 tarball>"
-  }
-}
-```
-
-### 2. Chunking
-
-For each file:
-1. Detect content type
-2. Select chunker (built-in or custom WASM)
-3. Chunk content
-4. Store chunks in eXist-db with metadata
-
-**Chunk metadata:**
-```json
-{
-  "id": "chunk-uuid",
-  "library_id": "lib-uuid",
-  "file_path": "src/BRepBuilderAPI/BRepBuilderAPI_MakeEdge.cxx",
-  "start_line": 142,
-  "end_line": 387,
-  "type": "function",
-  "name": "BRepBuilderAPI_MakeEdge::Build",
-  "language": "cpp",
-  "imports": ["gp_Pnt", "TopoDS_Edge", "BRepLib"],
-  "calls": ["GCPnts_TangentialDeflection", "BRep_Builder"],
-  "version": "v7.8.0",
-  "indexed_at": "2026-01-26T..."
-}
-```
-
-### 3. Indexing (Background)
-
-After chunking, RLM builds structural index:
-
-- **Call graph**: What calls what
-- **Type hierarchy**: Classes, inheritance
-- **Module map**: How code is organized
-- **Symbol table**: Functions, classes, constants
-- **Dependency graph**: Imports, includes
-
-This runs as a background job (can take hours for large codebases).

-
-### 1. Query
-
-```
-POST /api/v1/libraries/{id}/query
-{
-  "question": "Where are edges calculated?",
-  "max_tokens": 8000,
-  "include_sources": true
-}
-```
-
-### 2. RLM Processing
-
-The RLM receives:
-```
-You have access to a library "opencascade" with 2.3M lines of C++ code.
-
-Structural index available:
-- 4,231 classes
-- 47,892 functions  
-- 12 main modules: BRepBuilderAPI, BRepAlgoAPI, ...
-
-User question: "Where are edges calculated?"
-
-Available tools:
-- search(query) → relevant chunks
-- get_chunk(id) → full chunk content
-- get_structure(path) → module/class structure
-- recursive_query(sub_question) → ask yourself about a subset
-```
-
-RLM then:
-1. Searches for "edge" in symbol table
-2. Finds `BRepBuilderAPI_MakeEdge`, `BRepAlgo_EdgeConnector`, etc.
-3. Recursively queries: "What does BRepBuilderAPI_MakeEdge do?"
-4. Retrieves relevant chunks, synthesizes answer
-
-### 3. Response
-
-```json
-{
-  "answer": "Edge calculation in OpenCASCADE primarily happens in the BRepBuilderAPI module...",
-  
-  "sources": [
-    {
-      "file": "src/BRepBuilderAPI/BRepBuilderAPI_MakeEdge.cxx",
-      "lines": "142-387",
-      "relevance": 0.95,
-      "snippet": "void BRepBuilderAPI_MakeEdge::Build() { ... }"
-    },
-    {
-      "file": "src/BRepAlgo/BRepAlgo_EdgeConnector.cxx", 
-      "lines": "89-201",
-      "relevance": 0.82,
-      "snippet": "..."
-    }
-  ],
-  
-  "tokens_used": 47832,
-  "chunks_examined": 127,
-  "cost": "$0.34"
-}
-```
-
-## Storage (eXist-db)
-
-### Why eXist-db?
-
-- **Versioning**: Track codebase changes over time
-- **XML-native**: Fits with xml-pipeline philosophy
-- **XQuery**: Powerful querying for structured data
-- **Efficient**: Handles millions of documents
-

-## Pricing (Premium Tier)
-
-| Operation | Cost |
-|-----------|------|
-| Ingest (per 1M tokens) | $2.00 |
-| Index (per library) | $5.00 - $50.00 (depends on size) |
-| Query (per query) | $0.10 - $2.00 (depends on complexity) |
-| Storage (per GB/month) | $0.50 |
-
-**Why premium:**
-- Compute-intensive (lots of LLM calls)
-- Storage-intensive (versioned codebases)
-- High value (saves weeks of manual exploration)
-
-## Use Cases
-
-### 1. Legacy Code Understanding
-"I inherited a 500K line Fortran codebase. Help me understand the data flow."
-
-### 2. API Discovery
-"How do I create a NURBS surface with specific knot vectors?"
-
-### 3. Impact Analysis
-"What would break if I deprecated this function?"
-
-### 4. Onboarding
-"Explain the architecture of this codebase to a new developer."
-
-### 5. Code Review Assistance
-"Does this change follow the patterns used elsewhere in the codebase?"
-
-## Implementation Phases
-
-### Phase 1: MVP
-- [ ] Basic ingest (git clone, tarball upload)
-- [ ] Code chunker (Python, JavaScript, C++)
-- [ ] eXist-db storage
-- [ ] Simple RLM query (search + retrieve)
-
-### Phase 2: Full Chunkers
-- [ ] Prose chunker
-- [ ] Structured chunker (YAML/JSON/XML)
-- [ ] Tabular chunker
-- [ ] WASM chunker SDK
-
-### Phase 3: Deep Indexing
-- [ ] Call graph extraction
-- [ ] Type hierarchy
-- [ ] Cross-reference index
-- [ ] Incremental re-indexing on changes
-
-### Phase 4: Advanced Queries
-- [ ] Multi-turn conversations about code
-- [ ] "What if" analysis
-- [ ] Code generation informed by codebase patterns

-# BloxServer Frontend — v0 Prompt
-
-Build a Next.js 14+ frontend for BloxServer, a visual AI agent workflow builder. The UI paradigm is like **Excel meets n8n** — toolbar at top, tabs at bottom, flow canvas in the middle.
-
-## Tech Stack
-- **Framework:** Next.js 14 (App Router)
-- **Components:** shadcn/ui + Tailwind CSS
-- **Flow Canvas:** React Flow (@xyflow/react)
-- **Code Editor:** Monaco Editor (for YAML and WASM/AssemblyScript)
-- **State:** Zustand
-- **Auth:** Clerk
-- **API:** REST (see types below)
-
-## Pages
-
-| Route | Purpose |
-|-------|---------|
-| `/` | Landing page (marketing) |
-| `/dashboard` | Flow list, usage stats, quick actions |
-| `/flow/[id]` | Main flow editor (canvas + YAML tabs) |
-| `/flow/[id]/runs` | Execution history for a flow |
-| `/marketplace` | Browse/install tools and flow templates |
-| `/settings` | Account, billing, API keys |

-## Node Types
-
-| Type | Icon | Purpose |
-|------|------|---------|
-| `trigger` | 🎯 | Entry point (webhook, schedule, manual) |
-| `llmCall` | 🤖 | LLM agent (Claude, GPT, Grok) |
-| `httpRequest` | 🌐 | External API call |
-| `codeBlock` | 📝 | Custom WASM code (Pro) |
-| `conditional` | 🔀 | Branch based on condition |
-| `output` | 📤 | Terminal node / response |
-
-## Dashboard Features
-- List of user's flows (cards or table)
-- Flow status indicator (stopped/running/error)
-- Quick actions: New Flow, Import, Run
-- Usage stats (executions this month, limit)
-
-## Key UX Patterns
-1. **Bidirectional sync:** Canvas changes update YAML, YAML changes update canvas
-2. **Auto-save:** Changes saved automatically (debounced)
-3. **Run/Stop:** Single click to deploy/undeploy a flow
-4. **Execution history:** Click a run to see logs, input/output payloads
-5. **Node inspector:** Click a node to edit its config in a side panel

-## API Endpoints
-
-### Flows
-- `GET /flows` — List user's flows (returns `FlowSummary[]`)
-- `POST /flows` — Create flow
-- `GET /flows/:id` — Get full flow
-- `PATCH /flows/:id` — Update flow
-- `DELETE /flows/:id` — Delete flow
-- `POST /flows/:id/start` — Start flow (deploy container)
-- `POST /flows/:id/stop` — Stop flow
-
-### Triggers
-- `GET /flows/:id/triggers` — List triggers
-- `POST /flows/:id/triggers` — Create trigger
-- `DELETE /triggers/:id` — Delete trigger
-
-### Executions
-- `GET /flows/:id/executions` — List runs (paginated)
-- `GET /executions/:id` — Get run details
-- `GET /executions/:id/logs` — Stream logs (WebSocket)
-
-### Marketplace
-- `GET /marketplace` — Browse listings
-- `GET /marketplace/:id` — Get listing details
-- `POST /marketplace/:id/install` — Install to user's library
-
-### User
-- `GET /me` — Current user info + usage stats

-## Design Notes
-
-1. **Dark mode default** — Developer audience prefers dark
-2. **Keyboard shortcuts** — Cmd+S save, Cmd+Enter run, etc.
-3. **Toast notifications** — For save/run/error feedback
-4. **Loading states** — Skeleton loaders, not spinners
-5. **Mobile:** Dashboard is responsive, flow editor is desktop-only (show message on mobile)
-
----
-
-## Start With
-1. Dashboard page with flow list
-2. Flow editor with React Flow canvas
-3. Basic YAML tab (Monaco, read-only first)
-4. Run/Stop buttons that call API
-
-Then iterate: node inspector panel, execution history, marketplace.
