+# Release Command
+
+Review all changes in the repository and create a release with proper commit message, version tag, and push to remotes.
+
+## Argument: $ARGUMENTS
+
+The argument should be one of:
+- `patch` - Bump the patch version (e.g., v0.35.3 -> v0.35.4)
+- `minor` - Bump the minor version and reset patch to 0 (e.g., v0.35.3 -> v0.36.0)
+
+If no argument provided, default to `patch`.
+
+## Steps to perform:
+
+1. **Read the current version** from `pkg/version/version`
+
+2. **Calculate the new version** based on the argument:
+   - Parse the current version (format: vMAJOR.MINOR.PATCH)
+   - If `patch`: increment PATCH by 1
+   - If `minor`: increment MINOR by 1, set PATCH to 0
+
+3. **Update the version file** (`pkg/version/version`) with the new version
+
+4. **Review changes** using `git status` and `git diff --stat HEAD`
+
+5. **Compose a commit message** following this format:
+   - First line: 72 chars max, imperative mood summary
+   - Blank line
+   - Bullet points describing each significant change
+   - "Files modified:" section listing affected files
+   - Footer with Claude Code attribution
+
+6. **Stage all changes** with `git add -A`
+
+7. **Create the commit** with the composed message
+
+8. **Create a git tag** with the new version (e.g., `v0.36.0`)
+
+9. **Push to remotes** (origin and gitea) with tags:
+   ```
+   git push origin main --tags
+   git push gitea main --tags
+   ```
+
+10. **Report completion** with the new version and commit hash
+
+## Important:
+- Do NOT push to github remote (only origin and gitea)
+- Always verify the build compiles before committing: `CGO_ENABLED=0 go build -o /dev/null ./...`
+- If build fails, fix issues before proceeding

+# Feature Request and Bug Report Protocol
+
+This document describes how to submit effective bug reports and feature requests for ORLY relay. Following these guidelines helps maintainers understand and resolve issues quickly.
+
+## Before Submitting
+
+1. **Search existing issues** - Your issue may already be reported or discussed
+2. **Check documentation** - Review `CLAUDE.md`, `docs/`, and `pkg/*/README.md` files
+3. **Verify with latest version** - Ensure the issue exists in the current release
+4. **Test with default configuration** - Rule out configuration-specific problems
+
+## Bug Reports
+
+### Required Information
+
+**Title**: Concise summary of the problem
+- Good: "Kind 3 events with 8000+ follows truncated on save"
+- Bad: "Events not saving" or "Bug in database"
+
+**Environment**:
+```
+ORLY version: (output of ./orly version)
+OS: (e.g., Ubuntu 24.04, macOS 14.2)
+Go version: (output of go version)
+Database backend: (badger/neo4j/wasmdb)
+```
+
+**Configuration** (relevant settings only):
+```bash
+ORLY_DB_TYPE=badger
+ORLY_POLICY_ENABLED=true
+# Include any non-default settings
+```
+
+**Steps to Reproduce**:
+1. Start relay with configuration X
+2. Connect client and send event Y
+3. Query for event with filter Z
+4. Observe error/unexpected behavior
+
+**Expected Behavior**: What should happen
+
+**Actual Behavior**: What actually happens
+
+**Logs**: Include relevant log output with `ORLY_LOG_LEVEL=debug` or `trace`
+
+### Minimal Reproduction
+
+The most effective bug reports include a minimal reproduction case:
+
+```bash
+# Example: Script that demonstrates the issue
+export ORLY_LOG_LEVEL=debug
+./orly &
+sleep 2
+
+# Send problematic event
+echo '["EVENT", {...}]' | websocat ws://localhost:3334
+
+# Show the failure
+echo '["REQ", "test", {"kinds": [1]}]' | websocat ws://localhost:3334
+```
+
+Or provide a failing test case:
+
+```go
+func TestReproduceBug(t *testing.T) {
+    // Setup
+    db := setupTestDB(t)
+
+    // This should work but fails
+    event := createTestEvent(kind, content)
+    err := db.SaveEvent(ctx, event)
+    require.NoError(t, err)
+
+    // Query returns unexpected result
+    results, err := db.QueryEvents(ctx, filter)
+    assert.Len(t, results, 1) // Fails: got 0
+}
+```
+
+## Feature Requests
+
+### Required Information
+
+**Title**: Clear description of the feature
+- Good: "Add WebSocket compression support (permessage-deflate)"
+- Bad: "Make it faster" or "New feature idea"
+
+**Problem Statement**: What problem does this solve?
+```
+Currently, clients with high-latency connections experience slow sync times
+because event data is transmitted uncompressed. A typical session transfers
+50MB of JSON that could be reduced to ~10MB with compression.
+```
+
+**Proposed Solution**: How should it work?
+```
+Add optional permessage-deflate WebSocket extension support:
+- New config: ORLY_WS_COMPRESSION=true
+- Negotiate compression during WebSocket handshake
+- Apply to messages over configurable threshold (default 1KB)
+```
+
+**Use Case**: Who benefits and how?
+```
+- Mobile clients on cellular connections
+- Users syncing large follow lists
+- Relays with bandwidth constraints
+```
+
+**Alternatives Considered** (optional):
+```
+- Application-level compression: Rejected because it requires client changes
+- HTTP/2: Not applicable for WebSocket connections
+```
+
+### Implementation Notes (optional)
+
+If you have implementation ideas:
+
+```
+Suggested approach:
+1. Add compression config to app/config/config.go
+2. Modify gorilla/websocket upgrader in app/handle-websocket.go
+3. Add compression threshold check before WriteMessage()
+
+Reference: gorilla/websocket has built-in permessage-deflate support
+```
+
+## What Makes Reports Effective
+
+**Do**:
+- Be specific and factual
+- Include version numbers and exact error messages
+- Provide reproducible steps
+- Attach relevant logs (redact sensitive data)
+- Link to related issues or discussions
+- Respond to follow-up questions promptly
+
+**Avoid**:
+- Vague descriptions ("it doesn't work")
+- Multiple unrelated issues in one report
+- Assuming the cause without evidence
+- Demanding immediate fixes
+- Duplicating existing issues
+
+## Issue Labels
+
+When applicable, suggest appropriate labels:
+
+| Label | Use When |
+|-------|----------|
+| `bug` | Something isn't working as documented |
+| `enhancement` | New feature or improvement |
+| `performance` | Speed or resource usage issue |
+| `documentation` | Docs are missing or incorrect |
+| `question` | Clarification needed (not a bug) |
+| `good first issue` | Suitable for new contributors |
+
+## Response Expectations
+
+- **Acknowledgment**: Within a few days
+- **Triage**: Issue labeled and prioritized
+- **Resolution**: Depends on complexity and priority
+
+Complex features may require discussion before implementation. Bug fixes for critical issues are prioritized.
+
+## Following Up
+
+If your issue hasn't received attention:
+
+1. **Check issue status** - It may be labeled or assigned
+2. **Add new information** - If you've discovered more details
+3. **Politely bump** - A single follow-up comment after 2 weeks is appropriate
+4. **Consider contributing** - PRs that fix bugs or implement features are welcome
+
+## Contributing Fixes
+
+If you want to fix a bug or implement a feature yourself:
+
+1. Comment on the issue to avoid duplicate work
+2. Follow the coding patterns in `CLAUDE.md`
+3. Include tests for your changes
+4. Keep PRs focused on a single issue
+5. Reference the issue number in your PR
+
+## Security Issues
+
+**Do not report security vulnerabilities in public issues.**
+
+For security-sensitive bugs:
+- Contact maintainers directly
+- Provide detailed reproduction steps privately
+- Allow reasonable time for a fix before disclosure
+
+## Examples
+
+### Good Bug Report
+
+```markdown
+## WebSocket disconnects after 60 seconds of inactivity
+
+**Environment**:
+- ORLY v0.34.5
+- Ubuntu 22.04
+- Go 1.25.3
+- Badger backend
+
+**Steps to Reproduce**:
+1. Connect to relay: `websocat ws://localhost:3334`
+2. Send subscription: `["REQ", "test", {"kinds": [1], "limit": 1}]`
+3. Wait 60 seconds without sending messages
+4. Observe connection closed
+
+**Expected**: Connection remains open (Nostr relays should maintain persistent connections)
+
+**Actual**: Connection closed with code 1000 after exactly 60 seconds
+
+**Logs** (ORLY_LOG_LEVEL=debug):
+```
+1764783029014485🔎 client timeout, closing connection /app/handle-websocket.go:142
+```
+
+**Possible Cause**: May be related to read deadline not being extended on subscription activity
+```
+
+### Good Feature Request
+
+```markdown
+## Add rate limiting per pubkey
+
+**Problem**:
+A single pubkey can flood the relay with events, consuming storage and
+bandwidth. Currently there's no way to limit per-author submission rate.
+
+**Proposed Solution**:
+Add configurable rate limiting:
+```bash
+ORLY_RATE_LIMIT_EVENTS_PER_MINUTE=60
+ORLY_RATE_LIMIT_BURST=10
+```
+
+When exceeded, return OK false with "rate-limited" message per NIP-20.
+
+**Use Case**:
+- Public relays protecting against spam
+- Community relays with fair-use policies
+- Paid relays enforcing subscription tiers
+
+**Alternatives Considered**:
+- IP-based limiting: Ineffective because users share IPs and use VPNs
+- Global limiting: Punishes all users for one bad actor
+```

+## ⚠️ Bug Reports & Feature Requests
+
+**Bug reports and feature requests that do not follow the protocol will not be accepted.**
+
+Before submitting any issue, you must read and follow [BUG_REPORTS_AND_FEATURE_REQUEST_PROTOCOL.md](./BUG_REPORTS_AND_FEATURE_REQUEST_PROTOCOL.md).
+
+Requirements:
+- **Bug reports**: Include environment details, reproduction steps, expected/actual behavior, and logs
+- **Feature requests**: Include problem statement, proposed solution, and use cases
+- **Both**: Search existing issues first, verify with latest version, provide minimal reproduction
+
+Issues missing required information will be closed without review.
+
+## ⚠️ System Requirements
+
+> **IMPORTANT: ORLY requires a minimum of 500MB of free memory to operate.**
+>
+> The relay uses adaptive PID-controlled rate limiting to manage memory pressure. By default, it will:
+> - Auto-detect available system memory at startup
+> - Target 66% of available memory, capped at 1.5GB for optimal performance
+> - **Fail to start** if less than 500MB is available
+>
+> You can override the memory target with `ORLY_RATE_LIMIT_TARGET_MB` (e.g., `ORLY_RATE_LIMIT_TARGET_MB=2000` for 2GB).
+>
+> To disable rate limiting (not recommended): `ORLY_RATE_LIMIT_ENABLED=false`
+

+# Rate Limiting Test Report: Badger Backend
+
+**Test Date:** December 12, 2025
+**Test Duration:** 16 minutes (1,018 seconds)
+**Import File:** `wot_reference.jsonl` (2.7 GB, 2,158,366 events)
+
+## Configuration
+
+| Parameter | Value |
+|-----------|-------|
+| Database Backend | Badger |
+| Target Memory | 1,500 MB |
+| Emergency Threshold | 1,750 MB (target + 1/6) |
+| Recovery Threshold | 1,250 MB (target - 1/6) |
+| Max Write Delay | 1,000 ms (normal), 5,000 ms (emergency) |
+| Data Directory | `/tmp/orly-badger-test` |
+
+## Results Summary
+
+### Memory Management
+
+| Metric | Value |
+|--------|-------|
+| Peak RSS (VmHWM) | 2,892 MB |
+| Final RSS | 1,353 MB |
+| Target | 1,500 MB |
+| **Memory Controlled** | **Yes** (90% of target) |
+
+The rate limiter successfully controlled memory usage. While peak memory reached 2,892 MB before rate limiting engaged, the system was brought down to and stabilized at ~1,350 MB, well under the 1,500 MB target.
+
+### Rate Limiting Events
+
+| Event Type | Count |
+|------------|-------|
+| Emergency Mode Entries | 9 |
+| Emergency Mode Exits | 8 |
+| Compactions Triggered | 3 |
+| Compactions Completed | 3 |
+
+### Compaction Performance
+
+| Compaction | Duration |
+|------------|----------|
+| #1 | 8.16 seconds |
+| #2 | 8.75 seconds |
+| #3 | 8.76 seconds |
+| **Average** | **8.56 seconds** |
+
+### Import Throughput
+
+| Phase | Events/sec | MB/sec |
+|-------|------------|--------|
+| Initial (no throttling) | 93 | 1.77 |
+| After throttling | 31 | 0.26 |
+| **Throttle Factor** | **3x reduction** | |
+
+The rate limiter reduced import throughput by approximately 3x to maintain memory within target limits.
+
+### Import Progress
+
+- **Events Saved:** 30,978 (partial - test stopped for report)
+- **Data Read:** 258.70 MB
+- **Database Size:** 369 MB
+
+## Timeline
+
+```
+[00:00] Import started at 93 events/sec
+[00:20] Memory pressure triggered emergency mode (116.9% > 116.7% threshold)
+[00:20] Compaction #1 triggered
+[00:28] Compaction #1 completed (8.16s)
+[00:30] Emergency mode exited, memory recovered
+[01:00] Multiple emergency mode cycles as memory fluctuates
+[05:00] Throughput stabilized at ~50 events/sec
+[10:00] Throughput further reduced to ~35 events/sec
+[16:00] Test stopped at 31 events/sec, memory stable at 1,353 MB
+```
+
+## Import Rate Over Time
+
+```
+Time     Events/sec  Memory Status
+------   ----------  -------------
+00:05    93          Rising
+00:20    82          Emergency mode entered
+01:00    72          Recovering
+03:00    60          Stabilizing
+06:00    46          Controlled
+10:00    35          Controlled
+16:00    31          Stable at ~1,350 MB
+```
+
+## Key Observations
+
+### What Worked Well
+
+1. **Memory Control:** The PID-based rate limiter successfully prevented memory from exceeding the target for extended periods.
+
+2. **Emergency Mode:** The hysteresis-based emergency mode (enter at +16.7%, exit at -16.7%) prevented rapid oscillation between modes.
+
+3. **Automatic Compaction:** When emergency mode triggered, Badger compaction was automatically initiated, helping reclaim memory.
+
+4. **Progressive Throttling:** Write delays increased progressively with memory pressure, allowing smooth throughput reduction.
+
+### Areas for Potential Improvement
+
+1. **Initial Spike:** Memory peaked at 2,892 MB before rate limiting could respond. Consider more aggressive initial throttling or pre-warming.
+
+2. **Throughput Trade-off:** Import rate dropped from 93 to 31 events/sec (3x reduction). This is the expected cost of memory control.
+
+3. **Sustained Emergency Mode:** The test showed 9 entries but only 8 exits, indicating the system was in emergency mode at test end. This is acceptable behavior when load is continuous.
+
+## Conclusion
+
+The adaptive rate limiting system with emergency mode and automatic compaction **successfully controlled memory usage** for the Badger backend. The system:
+
+- Prevented sustained memory overflow beyond the target
+- Automatically triggered compaction during high memory pressure
+- Smoothly reduced throughput to maintain stability
+- Demonstrated effective hysteresis to prevent mode oscillation
+
+**Recommendation:** The rate limiting implementation is ready for production use with Badger backend. For high-throughput imports, users should expect approximately 3x reduction in import speed when memory limits are active.
+
+## Test Environment
+
+- **OS:** Linux 6.8.0-87-generic
+- **Architecture:** x86_64
+- **Go Version:** 1.25.3
+- **Badger Version:** v4

+# Rate Limiting Test Report: Neo4j Backend
+
+**Test Date:** December 12, 2025
+**Test Duration:** 73 minutes (4,409 seconds)
+**Import File:** `wot_reference.jsonl` (2.7 GB, 2,158,366 events)
+
+## Configuration
+
+| Parameter | Value |
+|-----------|-------|
+| Database Backend | Neo4j 5-community (Docker) |
+| Target Memory | 1,500 MB (relay process) |
+| Emergency Threshold | 1,167 (target + 1/6) |
+| Recovery Threshold | 833 (target - 1/6) |
+| Max Write Delay | 1,000 ms (normal), 5,000 ms (emergency) |
+| Neo4j Memory Limits | Heap: 512MB-1GB, Page Cache: 512MB |
+
+## Results Summary
+
+### Memory Management
+
+| Component | Metric | Value |
+|-----------|--------|-------|
+| **Relay Process** | Peak RSS (VmHWM) | 148 MB |
+| **Relay Process** | Final RSS | 35 MB |
+| **Neo4j Container** | Memory Usage | 1.614 GB |
+| **Neo4j Container** | Memory % | 10.83% of 14.91GB |
+| **Rate Limiting** | Events Triggered | **0** |
+
+### Key Finding: Architecture Difference
+
+Unlike Badger (embedded database), Neo4j runs as a **separate process** in a Docker container. This means:
+
+1. **Relay process memory stays low** (~35MB) because it's just a client
+2. **Neo4j manages its own memory** within the container (1.6GB used)
+3. **Rate limiter monitors relay RSS**, which doesn't reflect Neo4j's actual load
+4. **No rate limiting triggered** because relay memory never approached the 1.5GB target
+
+This is architecturally correct - the relay doesn't need memory-based rate limiting for Neo4j because it's not holding the data in process.
+
+### Event Processing
+
+| Event Type | Count | Rate |
+|------------|-------|------|
+| Contact Lists (kind 3) | 174,836 | 40 events/sec |
+| Mute Lists (kind 10000) | 4,027 | 0.9 events/sec |
+| **Total Social Events** | **178,863** | **41 events/sec** |
+
+### Neo4j Performance
+
+| Metric | Value |
+|--------|-------|
+| CPU Usage | 40-45% |
+| Memory | Stable at 1.6GB |
+| Disk Writes | 12.7 GB |
+| Network In | 1.8 GB |
+| Network Out | 583 MB |
+| Process Count | 77-82 |
+
+### Import Throughput Over Time
+
+```
+Time      Contact Lists  Delta/min  Neo4j Memory
+------    -------------  ---------  ------------
+08:28     0              -          1.57 GB
+08:47     31,257         ~2,100     1.61 GB
+08:52     42,403         ~2,200     1.61 GB
+09:02     67,581         ~2,500     1.61 GB
+09:12     97,316         ~3,000     1.60 GB
+09:22     112,681        ~3,100     1.61 GB
+09:27     163,252        ~10,000*   1.61 GB
+09:41     174,836        ~2,400     1.61 GB
+```
+*Spike may be due to batch processing of cached events
+
+### Memory Stability
+
+Neo4j's memory usage remained remarkably stable throughout the test:
+
+```
+Sample      Memory     Delta
+--------    --------   -----
+08:47       1.605 GB   -
+09:02       1.611 GB   +6 MB
+09:12       1.603 GB   -8 MB
+09:27       1.607 GB   +4 MB
+09:41       1.614 GB   +7 MB
+```
+
+**Variance:** < 15 MB over 73 minutes - excellent stability.
+
+## Architecture Comparison: Badger vs Neo4j
+
+| Aspect | Badger | Neo4j |
+|--------|--------|-------|
+| Database Type | Embedded | External (Docker) |
+| Memory Consumer | Relay process | Container process |
+| Rate Limiter Target | Relay RSS | Relay RSS |
+| Rate Limiting Effectiveness | High | Low* |
+| Compaction Triggering | Yes | N/A |
+| Emergency Mode | Yes | Not triggered |
+
+*The current rate limiter design targets relay process memory, which doesn't reflect Neo4j's actual resource usage.
+
+## Recommendations for Neo4j Rate Limiting
+
+The current implementation monitors **relay process memory**, but for Neo4j this should be enhanced to monitor:
+
+### 1. Query Latency-Based Throttling (Currently Implemented)
+The Neo4j monitor already tracks query latency via `RecordQueryLatency()` and `RecordWriteLatency()`, using EMA smoothing. Latency > 500ms increases reported load.
+
+### 2. Connection Pool Saturation (Currently Implemented)
+The `querySem` semaphore limits concurrent queries (default 10). When full, the load metric increases.
+
+### 3. Future Enhancement: Container Metrics
+Consider monitoring Neo4j container metrics via:
+- Docker stats API for memory/CPU
+- Neo4j metrics endpoint for transaction counts, cache hit rates
+- JMX metrics for heap usage and GC pressure
+
+## Conclusion
+
+The Neo4j import test demonstrated:
+
+1. **Stable Memory Usage**: Neo4j maintained consistent 1.6GB memory throughout
+2. **Consistent Throughput**: ~40 social events/second with no degradation
+3. **Architectural Isolation**: Relay stays lightweight while Neo4j handles data
+4. **Rate Limiter Design**: Current RSS-based limiting is appropriate for Badger but less relevant for Neo4j
+
+**Recommendation:** The Neo4j rate limiter is correctly implemented but relies on latency and concurrency metrics rather than memory pressure. For production deployments with Neo4j, configure appropriate Neo4j memory limits in the container (heap_initial, heap_max, pagecache) rather than relying on relay-side rate limiting.

+
+## EventStore
+
+The foundational class for managing Nostr event state.
+
+### Creation
+
+```typescript
+import { EventStore } from "applesauce-core";
+
+// Memory-only store
+const eventStore = new EventStore();
+
+// With persistent database
+import { BetterSqlite3EventDatabase } from "applesauce-core/database";
+const database = new BetterSqlite3EventDatabase("./events.db");
+const eventStore = new EventStore(database);
+```
+
+### Event Management Methods
+
+```typescript
+// Add event (returns existing if duplicate, null if rejected)
+eventStore.add(event, relay?);
+
+// Remove events
+eventStore.remove(id);
+eventStore.remove(event);
+eventStore.removeByFilters(filters);
+
+// Update event (notify store of modifications)
+eventStore.update(event);
+```
+
+### Query Methods
+
+```typescript
+// Check existence
+eventStore.hasEvent(id);
+
+// Get single event
+eventStore.getEvent(id);
+
+// Get by filters
+eventStore.getByFilters(filters);
+
+// Get sorted timeline (newest first)
+eventStore.getTimeline(filters);
+
+// Replaceable events
+eventStore.hasReplaceable(kind, pubkey);
+eventStore.getReplaceable(kind, pubkey, identifier?);
+eventStore.getReplaceableHistory(kind, pubkey, identifier?); // requires keepOldVersions: true
+```
+
+### Observable Subscriptions
+
+```typescript
+// Single event updates
+eventStore.event(id).subscribe(event => { ... });
+
+// All matching events
+eventStore.filters(filters, onlyNew?).subscribe(events => { ... });
+
+// Sorted event arrays
+eventStore.timeline(filters, onlyNew?).subscribe(events => { ... });
+
+// Replaceable events
+eventStore.replaceable(kind, pubkey).subscribe(event => { ... });
+
+// Addressable events
+eventStore.addressable(kind, pubkey, identifier).subscribe(event => { ... });
+```
+
+### Helper Subscriptions
+
+```typescript
+// Profile (kind 0)
+eventStore.profile(pubkey).subscribe(profile => { ... });
+
+// Contacts (kind 3)
+eventStore.contacts(pubkey).subscribe(contacts => { ... });
+
+// Mutes (kind 10000)
+eventStore.mutes(pubkey).subscribe(mutes => { ... });
+
+// Mailboxes/NIP-65 relays (kind 10002)
+eventStore.mailboxes(pubkey).subscribe(mailboxes => { ... });
+
+// Blossom servers (kind 10063)
+eventStore.blossomServers(pubkey).subscribe(servers => { ... });
+
+// Reactions (kind 7)
+eventStore.reactions(event).subscribe(reactions => { ... });
+
+// Thread replies
+eventStore.thread(eventId).subscribe(thread => { ... });
+
+// Comments
+eventStore.comments(event).subscribe(comments => { ... });
+```
+
+### NIP-91 AND Operators
+
+```typescript
+// Use & prefix for tags requiring ALL values
+eventStore.filters({
+  kinds: [1],
+  "&t": ["meme", "cat"],    // Must have BOTH tags
+  "#t": ["black", "white"]  // Must have black OR white
+});
+```
+
+### Fallback Loaders
+
+```typescript
+// Custom async loaders for missing events
+eventStore.eventLoader = async (pointer) => {
+  // Fetch from relay and return event
+};
+
+eventStore.replaceableLoader = async (pointer) => { ... };
+eventStore.addressableLoader = async (pointer) => { ... };
+```
+
+### Configuration
+
+```typescript
+const eventStore = new EventStore();
+
+// Keep all versions of replaceable events
+eventStore.keepOldVersions = true;
+
+// Keep expired events (default: removes them)
+eventStore.keepExpired = true;
+
+// Custom verification
+eventStore.verifyEvent = (event) => verifySignature(event);
+
+// Model memory duration (default: 60000ms)
+eventStore.modelKeepWarm = 60000;
+```
+
+### Memory Management
+
+```typescript
+// Mark event as in-use
+eventStore.claim(event, claimId);
+
+// Check if claimed
+eventStore.isClaimed(event);
+
+// Remove claims
+eventStore.removeClaim(event, claimId);
+eventStore.clearClaim(event);
+
+// Prune unclaimed events
+eventStore.prune(count?);
+
+// Iterate unclaimed (LRU ordered)
+for (const event of eventStore.unclaimed()) { ... }
+```
+
+### Observable Streams
+
+```typescript
+// New events added
+eventStore.insert$.subscribe(event => { ... });
+
+// Events modified
+eventStore.update$.subscribe(event => { ... });
+
+// Events deleted
+eventStore.remove$.subscribe(event => { ... });
+```
+
+---
+
+## EventFactory
+
+Primary interface for creating, building, and modifying Nostr events.
+
+### Initialization
+
+```typescript
+import { EventFactory } from "applesauce-factory";
+
+// Basic
+const factory = new EventFactory();
+
+// With signer
+const factory = new EventFactory({ signer: mySigner });
+
+// Full configuration
+const factory = new EventFactory({
+  signer: { getPublicKey, signEvent, nip04?, nip44? },
+  client: { name: "MyApp", address: "31990:..." },
+  getEventRelayHint: (eventId) => "wss://relay.example.com",
+  getPubkeyRelayHint: (pubkey) => "wss://relay.example.com",
+  emojis: emojiArray
+});
+```
+
+### Blueprint-Based Creation
+
+```typescript
+import { NoteBlueprint, ReactionBlueprint } from "applesauce-factory/blueprints";
+
+// Pattern 1: Constructor + arguments
+const note = await factory.create(NoteBlueprint, "Hello Nostr!");
+const reaction = await factory.create(ReactionBlueprint, event, "+");
+
+// Pattern 2: Direct blueprint call
+const note = await factory.create(NoteBlueprint("Hello Nostr!"));
+```
+
+### Custom Event Building
+
+```typescript
+import { setContent, includeNameValueTag, includeSingletonTag } from "applesauce-factory/operations";
+
+const event = await factory.build(
+  { kind: 30023 },
+  setContent("Article content..."),
+  includeNameValueTag(["title", "My Title"]),
+  includeSingletonTag(["d", "article-id"])
+);
+```
+
+### Event Modification
+
+```typescript
+import { addPubkeyTag } from "applesauce-factory/operations";
+
+// Full modification
+const modified = await factory.modify(existingEvent, operations);
+
+// Tags only
+const updated = await factory.modifyTags(existingEvent, addPubkeyTag("pubkey"));
+```
+
+### Helper Methods
+
+```typescript
+// Short text note (kind 1)
+await factory.note("Hello world!", options?);
+
+// Reply to note
+await factory.noteReply(parentEvent, "My reply");
+
+// Reaction (kind 7)
+await factory.reaction(event, "🔥");
+
+// Event deletion
+await factory.delete(events, reason?);
+
+// Repost/share
+await factory.share(event);
+
+// NIP-22 comment
+await factory.comment(article, "Great article!");
+```

+      map(event => event ? JSON.parse(event.content) : null)
+    );
+  };
+};
+

+
+```typescript
+import { EventStore } from "applesauce-core";
+import { EventFactory } from "applesauce-factory";
+import { NoteBlueprint } from "applesauce-factory/blueprints";
+
+// Initialize stores
+const eventStore = new EventStore();
+const factory = new EventFactory({ signer: mySigner });
+
+// Subscribe to timeline
+eventStore.timeline({ kinds: [1], limit: 50 }).subscribe(notes => {
+  renderNotes(notes);
+});
+
+// Create a new note
+const note = await factory.create(NoteBlueprint, "Hello Nostr!");
+
+// Add to store
+eventStore.add(note);
+```
+
+### Profile Display
+
+```typescript
+// Subscribe to profile updates
+eventStore.profile(pubkey).subscribe(event => {
+  if (event) {
+    const profile = getProfileContent(event);
+    displayProfile(profile);
+  }
+});
+```
+
+### Reactive Reactions
+
+```typescript
+// Subscribe to reactions on an event
+eventStore.reactions(targetEvent).subscribe(reactions => {
+  const likeCount = reactions.filter(r => r.content === "+").length;
+  updateLikeButton(likeCount);
+});
+
+// Add a reaction
+const reaction = await factory.reaction(targetEvent, "🔥");
+eventStore.add(reaction);
+```
+
+### Thread Loading
+
+```typescript
+eventStore.thread(rootEventId).subscribe(thread => {
+  renderThread(thread);
+});
+```
+
+---
+
+## Nostr Event Kinds Reference
+
+| Kind | Description |
+|------|-------------|
+| 0 | Profile metadata |
+| 1 | Short text note |
+| 3 | Contact list |
+| 7 | Reaction |
+| 10000 | Mute list |
+| 10002 | Relay list (NIP-65) |
+| 10063 | Blossom servers |
+| 30023 | Long-form content |
+| 30078 | App-specific data (NIP-78) |

+## Key Interfaces
+
+### Tunnel Interface
+```go
+type Tunnel interface {
+    Connect(ctx context.Context) error
+    Disconnect() error
+    Status() TunnelStatus
+    Handoff() (*HandoffState, error)
+    Resume(state *HandoffState) error
+}
+```
+
+### Admin API Interface
+```go
+type AdminAPI interface {
+    Status() (*RelayStatus, error)
+    Start() error
+    Stop() error
+    Restart() error
+    Logs(ctx context.Context, lines int) (<-chan LogEntry, error)
+}
+```
+
+### Tray Interface
+```go
+type TrayApp interface {
+    Run() error
+    Quit()
+    UpdateStatus(status StatusLevel, tooltip string)
+    ShowNotification(title, message string)
+}
+```
+
+---
+
+## Dependencies to Add
+
+```go
+// go.mod additions
+require (
+    github.com/wailsapp/wails/v2 v2.x.x      // Installer GUI
+    golang.zx2c4.com/wireguard v0.x.x        // WireGuard client
+    github.com/getlantern/systray v1.x.x     // System tray (or fyne.io/systray)
+)
+```
+
+---
+
+## Build Commands
+
+```bash
+# Standard relay build (unchanged)
+CGO_ENABLED=0 go build -o orly
+
+# Relay with tray support
+CGO_ENABLED=0 go build -tags tray -o orly
+
+# Installer GUI
+cd cmd/orly-setup && wails build -platform linux/amd64,darwin/amd64
+
+# Proxy server
+CGO_ENABLED=0 go build -o orly-proxy ./cmd/proxy-server
+
+# All platforms
+./scripts/build-all.sh
+```
+
+---
+
+## Critical Files Reference
+
+| File | Purpose |
+|------|---------|
+| `app/config/config.go` | Add WG, tray, admin API config |
+| `app/server.go` | Register admin API routes |
+| `main.go` | Add --tray flag, WG initialization |
+| `scripts/deploy.sh` | Pattern for installer service creation |
+| `app/web/src/App.svelte` | Pattern for installer UI |
+
+---
+
+## Backward Compatibility
+
+- Main `orly` binary behavior unchanged without flags
+- All new features opt-in via environment variables
+- WireGuard gracefully degrades if connection fails
+- Tray mode only activates with `--tray` flag
+- Admin API can be disabled via `ORLY_ADMIN_API_ENABLED=false`
+
+---
+
+## Success Criteria
+
+1. New user can install via GUI wizard in < 5 minutes
+2. README guides user from zero to running relay
+3. System tray provides one-click relay management
+4. WireGuard tunnel auto-connects and reconnects
+5. Proxy server enables home relay exposure without port forwarding
+6. All existing functionality preserved
