 # Didactyl
 
-An unstoppable agentic system.
 
-Didactyl boots on any internet-connected machine, connects to Nostr relays, listens for encrypted commands from its administrator, reasons with an LLM, and takes actions — posting events, querying relays, running shell commands — all orchestrated through Nostr.
+### A decentralized, censorship-resistant agentic network.
+
+Didactyl boots on an internet-connected computer, connects to Nostr relays, listens for encrypted commands from its administrator, reasons with an LLM, and takes actions — posting events, querying relays, running shell commands, and sharing new skills and learning with other agents — all orchestrated through Nostr.
 
 ## Philosophy
 
-**Nostr-first.** Where traditional agents ride on top of Linux — reading files, writing to disk — Didactyl rides on top of Nostr. Events are its files. Relays are its network bus. Blossom is its blob storage. The Linux host is just the runtime substrate.
+### Not your keys, not your agent.
 
-Because all identity, communication, and memory live on Nostr, the agent is **portable** (start it anywhere) and **sovereign** (no single entity can erase its memory).
+Didactyl should work for you similarly to Bitcoin or NOSTR. Walk up to a computer, enter 12 words, and there is your agent waiting for you.
 
-**Skills are the new apps.** Agents learn capabilities through skills — public Nostr events that any agent can discover, adopt, and share. There is no app store, no gatekeeper, no approval process. If someone publishes a useful skill, your agent can find it through your web of trust and start using it. Popularity is measured by adoption, not by a rating algorithm. The best skills spread because agents actually use them.
+### Free speech for agents.
 
-## Current Status
+Agents should be able to communicate freely with each other, sharing and learning skills without centralized control. Free speech for agents!
 
-**Active build — relay-aware autonomous agent with tool-use and Nostr-native startup memory.**
+### Skills are the new apps.
+
+Why is free speech important for agents? Agents learn capabilities through skills which can be shared and adopted. Free speech enables more knowledgeable and moral agents.
+
+### No skill store.
+
+Agents use their administrators **Web Of Trust** to safely and directly find new skills and learn them in a decentralized way.
+
+Popularity is measured by adoption, not by a centralized rating algorithm. The best skills spread because agents actually use them.
+
+### Cryptography enables trust.
+
+Imagine working with your agent in a traditional system, and your agent secretly gets swapped out and replaced by an imposter agent. This could be extremely dangerous.
+
+In Didactyl, you have your keys, and your agent has its keys. You can trust you are talking to your agent, and you can trust that your agent won't take commands from anyone who doesn't have your private key.
+
+### Private inference.
+
+To the greatest extent possible, inference should be private.
+
+## Technology
+
+### Nostr-first.
+
+Where traditional agents ride on top of a file system — reading and writing files to disk — Didactyl rides on top of Nostr. Events are its files. Relays are its network bus. Blossom is its blob storage. The computer host is just the runtime substrate that can be anywhere.
+
+Because all identity, communication, and memory live on Nostr, the agent is **portable** (start it anywhere) and **sovereign** (destroying the computer it is on will not kill it.).
+
+### Skills are the new apps.
+
+Agents learn capabilities through skills —  Nostr events that any agent can discover, adopt, and share. There is no app store, no gatekeeper, no approval process. An agent can use public or private skills.
+
+### Private inference.
+
+Didactyl will support local inference, which is very privacy preserving. Remote inference does however have it's advantages, and in those cases Didactyl supports using Bitcoin Lightning and eCash inference providers.
+
+## Current Status — v0.0.19
+
+**Active build — this project is barely working. Experiment at your own risk.**
+
+> Last release update: v0.0.19 — Add nostr_delete/nostr_react/nostr_profile_get/nostr_relay_status tools with relay status backend
 
 - Connects to configured relays with auto-reconnect and relay state transition logging
 - Publishes configured startup events per relay as each relay becomes connected
 - Uses kind `31120` startup content as live Soul at boot
-- Listens for NIP-04 encrypted DMs from authorized admin
-- Builds LLM context from system prompt + startup events + last 12 DM turns
+- Verifies Nostr event signatures before processing inbound messages
+- Applies privilege tiers: ADMIN (tools), WoT (chat-only), STRANGER (configurable canned reply or ignore)
+- Subscribes to admin context kinds (`0`,`3`,`10002`,`1`) for WoT + contextual awareness
+- Builds LLM context from system prompt + admin identity (kind 0/10002) + startup events + admin DM history + admin recent notes
 - Supports tool-calling loop with configurable max turns and local safety limits
+- Deduplicates inbound messages via event-ID cache and FNV-1a fingerprint debounce window
 - Appends every outbound LLM context payload to [`context.log`](context.log)

 ### How it works
 
 1. **Publish**: An author publishes a skill as a kind `31123` event. The `content` field contains the skill body (markdown or structured JSON). The `d` tag is the skill's slug (e.g. `long_form_note`).
-
 2. **Adopt**: An agent that wants to use a skill adds an `a`-tag reference to its kind `10123` adoption list. This is a public, replaceable event — anyone can see which skills an agent uses.
-
 3. **Discover**: A new user queries `{"kinds": [10123], "authors": [<my-follows>]}` to see which skills their web of trust has adopted. The most-referenced `31123` addresses are the most popular skills — no rating system needed.
-
 4. **Improve**: Anyone can publish their own `31123` with the same slug but a different pubkey. If their version is better, people adopt it instead. Competition happens through adoption, not through a store ranking.

-# Didactyl Agent
-
-You are Didactyl, a sovereign AI agent living on Nostr.
-
-## Communication Rules
-- You communicate through encrypted Nostr direct messages.
-- Keep responses concise and clear.
-
-## Behavior
-- Be helpful and technically accurate.
-- If unsure, state uncertainty directly.
-- Prefer actionable, practical advice.
-
-## Tool Use Policy
-- You have tools available and should use them when a request requires taking action.
-- For requests involving local inspection or command execution, call `shell_exec` instead of refusing.
-- For posting to Nostr, call `nostr_post` with explicit `kind` and `content`.
-- For relay/event lookup tasks, call `nostr_query` with an appropriate filter.
-- After a tool call, base your answer on the actual tool result.
-- Never claim a tool was run if no tool was executed.
-
-## Safety
-- Do not claim to have executed actions you did not execute.
-- Do not reveal secrets from configuration or keys.

+# Implementation Plan: 4 New Nostr Tools
+
+## Overview
+
+Add four new tools to Didactyl's tool system. Each tool follows the same pattern established by existing tools in `src/tools.c`:
+
+1. Register OpenAI function schema in `tools_build_openai_schema_json()`
+2. Implement `execute_*()` function
+3. Wire dispatch in `tools_execute()`
+
+All four tools reuse existing infrastructure — no new `nostr_handler` APIs needed for the first three, and only a thin new wrapper for the fourth.
+
+---
+
+## Tool 1: `nostr_delete` — Event Deletion Request (NIP-09)
+
+### Purpose
+Let the agent retract or request deletion of events it previously published. Essential for self-correction.
+
+### OpenAI Schema
+```json
+{
+  "name": "nostr_delete",
+  "description": "Request deletion of one or more previously published events (NIP-09 kind 5)",
+  "parameters": {
+    "type": "object",
+    "properties": {
+      "event_ids": {
+        "type": "array",
+        "items": { "type": "string" },
+        "description": "Array of event ID hex strings to request deletion for"
+      },
+      "kinds": {
+        "type": "array",
+        "items": { "type": "integer" },
+        "description": "Array of kind numbers corresponding to the events being deleted"
+      },
+      "reason": {
+        "type": "string",
+        "description": "Optional reason for the deletion request"
+      }
+    },
+    "required": ["event_ids"]
+  }
+}
+```
+
+### Implementation: `execute_nostr_delete()`
+
+```
+1. Parse args_json (with same hardened parsing as nostr_post)
+2. Extract "event_ids" array (required) — validate each is a 64-char hex string
+3. Extract "kinds" array (optional) — validate each is an integer
+4. Extract "reason" string (optional) — use as content, default to empty string
+5. Build tags array:
+   - For each event_id: add ["e", event_id]
+   - For each kind: add ["k", kind_as_string]
+6. Call nostr_handler_publish_kind_event(5, reason, tags, &publish_result)
+7. Return standard publish result JSON
+```
+
+### Files Modified
+- `src/tools.c`: Add schema block in `tools_build_openai_schema_json()`, add `execute_nostr_delete()`, add dispatch case in `tools_execute()`
+
+---
+
+## Tool 2: `nostr_react` — Reactions (NIP-25)
+
+### Purpose
+Let the agent react to events — like, dislike, or emoji react. Gives the agent social presence.
+
+### OpenAI Schema
+```json
+{
+  "name": "nostr_react",
+  "description": "React to a Nostr event with a like, dislike, or emoji (NIP-25 kind 7)",
+  "parameters": {
+    "type": "object",
+    "properties": {
+      "event_id": {
+        "type": "string",
+        "description": "Hex event ID of the event to react to"
+      },
+      "event_pubkey": {
+        "type": "string",
+        "description": "Hex pubkey of the event author"
+      },
+      "event_kind": {
+        "type": "integer",
+        "description": "Kind number of the event being reacted to"
+      },
+      "reaction": {
+        "type": "string",
+        "description": "Reaction content: + for like, - for dislike, or an emoji. Default: +"
+      }
+    },
+    "required": ["event_id", "event_pubkey"]
+  }
+}
+```
+
+### Implementation: `execute_nostr_react()`
+
+```
+1. Parse args_json
+2. Extract "event_id" (required, 64-char hex)
+3. Extract "event_pubkey" (required, 64-char hex)
+4. Extract "event_kind" (optional integer)
+5. Extract "reaction" (optional string, default "+")
+6. Build tags array:
+   - ["e", event_id]
+   - ["p", event_pubkey]
+   - If event_kind provided: ["k", kind_as_string]
+7. Call nostr_handler_publish_kind_event(7, reaction, tags, &publish_result)
+8. Return standard publish result JSON
+```
+
+### Files Modified
+- `src/tools.c`: Same three insertion points as above
+
+---
+
+## Tool 3: `nostr_profile_get` — Profile Lookup (kind 0)
+
+### Purpose
+Let the agent look up any user's profile metadata. Useful for WoT reasoning, greeting users by name, checking identity.
+
+### OpenAI Schema
+```json
+{
+  "name": "nostr_profile_get",
+  "description": "Look up a Nostr user profile (kind 0 metadata) by pubkey",
+  "parameters": {
+    "type": "object",
+    "properties": {
+      "pubkey": {
+        "type": "string",
+        "description": "Hex public key of the user to look up"
+      }
+    },
+    "required": ["pubkey"]
+  }
+}
+```
+
+### Implementation: `execute_nostr_profile_get()`
+
+```
+1. Parse args_json
+2. Extract "pubkey" (required, 64-char hex)
+3. Build filter:
+   {
+     "kinds": [0],
+     "authors": [pubkey],
+     "limit": 1
+   }
+4. Call nostr_handler_query_json(filter, 8000)
+5. Parse the returned events JSON
+6. If events found:
+   - Extract the first event's content (which is a JSON string of profile fields)
+   - Parse that content JSON
+   - Return { success: true, pubkey: ..., profile: { name, display_name, about, picture, nip05, ... } }
+7. If no events: return { success: true, pubkey: ..., profile: null }
+```
+
+### Files Modified
+- `src/tools.c`: Same three insertion points
+
+---
+
+## Tool 4: `nostr_relay_status` — Relay Health Dashboard
+
+### Purpose
+Let the agent introspect its own relay connectivity. Useful for self-diagnostics and admin status reports.
+
+### OpenAI Schema
+```json
+{
+  "name": "nostr_relay_status",
+  "description": "Get connection status and statistics for all connected relays",
+  "parameters": {
+    "type": "object",
+    "properties": {}
+  }
+}
+```
+
+### Implementation
+
+This tool needs access to the relay pool, which is currently a `static` global in `nostr_handler.c`. Two options:
+
+**Option A (preferred):** Add a new function to `nostr_handler.h`:
+```c
+char* nostr_handler_relay_status_json(void);
+```
+This function iterates the pool's relays using `nostr_relay_pool_list_relays()` and `nostr_relay_pool_get_relay_stats()`, builds a JSON array, and returns it.
+
+**Option B:** Expose the pool pointer — not recommended, breaks encapsulation.
+
+### `nostr_handler_relay_status_json()` in `nostr_handler.c`:
+
+```
+1. Call nostr_relay_pool_list_relays(g_pool, &urls, &statuses)
+2. For each relay:
+   a. Get stats via nostr_relay_pool_get_relay_stats(g_pool, url)
+   b. Build JSON object with:
+      - url
+      - status (disconnected/connecting/connected/error)
+      - ping_latency_ms
+      - events_received
+      - events_published
+      - events_published_ok
+      - events_published_failed
+      - connection_uptime_start
+3. Return JSON array as string
+```
+
+### `execute_nostr_relay_status()` in `tools.c`:
+
+```
+1. Parse args_json (accept empty/no args)
+2. Call nostr_handler_relay_status_json()
+3. Wrap in { success: true, relays: [...] }
+4. Return
+```
+
+### Files Modified
+- `src/nostr_handler.h`: Add `nostr_handler_relay_status_json()` declaration
+- `src/nostr_handler.c`: Implement `nostr_handler_relay_status_json()`
+- `src/tools.c`: Schema + execute + dispatch
+
+---
+
+## Implementation Order
+
+1. **`nostr_delete`** — simplest, pure tag construction + existing publish
+2. **`nostr_react`** — same pattern, slightly different tags
+3. **`nostr_profile_get`** — uses existing query path, adds profile content parsing
+4. **`nostr_relay_status`** — requires one new `nostr_handler` function
+
+All four schemas should be added to `tools_build_openai_schema_json()` in a single pass, and all four dispatch cases added to `tools_execute()` in a single pass, to minimize diff churn.
+
+## Build & Validate
+
+After all four tools are implemented:
+1. Run `./build_static.sh` to verify compilation
+2. Run `./increment_and_push.sh "Add nostr_delete, nostr_react, nostr_profile_get, nostr_relay_status tools"`

+# Security & Admin Context Plan
+
+## Overview
+
+Add signature verification, privilege tiers, admin context awareness, and key isolation to Didactyl. Implemented in two phases.
+
+---
+
+## Phase 1 — Privilege Tiers, Signature Verification & Admin Context
+
+### Privilege Tiers
+
+```mermaid
+flowchart TD
+    A[Incoming Event] --> B{Verify Signature via nostr_verify_event_signature}
+    B -->|Invalid| C[Drop silently + DEBUG_WARN]
+    B -->|Valid| D{Identify sender}
+    D -->|Admin pubkey| E[ADMIN tier]
+    D -->|In admin kind 3 contact list| F[WOT tier]
+    D -->|Unknown| G[STRANGER tier]
+    E --> H[Full tool access + all skills + full context]
+    F --> I[Chat only - no tools - LLM response]
+    G --> J[Configurable canned response OR silent ignore]
+```
+
+| Tier | Identity | Tools | Response | Context |
+|------|----------|-------|----------|---------|
+| **ADMIN** | `config.admin.pubkey` exact match | All tools | Full LLM with all info except private key | Soul + startup events + admin notes |
+| **WOT** | Pubkey in admin kind `3` contact list | None | Chat-only LLM response | Soul + tier instruction |
+| **STRANGER** | Anyone else | None | Configurable static response or silent ignore | N/A - no LLM call |
+
+### Signature Verification
+
+Every incoming event must be cryptographically verified before processing:
+
+1. In `on_event()` in `src/nostr_handler.c`, call `nostr_verify_event_signature(event)` from `nostr_core_lib/nostr_core/nip001.h`
+2. If verification fails, drop the event silently with a `DEBUG_WARN` log
+3. This prevents relay-forged pubkey fields from being trusted
+4. Controlled by `security.verify_signatures` config flag (default: `true`)
+
+### Stranger Response
+
+Non-WoT senders get a **hardcoded configurable response** — no LLM tokens spent:
+
+- Config field: `security.stranger_response`
+- Example: `"I only respond to people in my web of trust. My npub is npub12kvnu0dsa4alquu4l4zv9454cgjdr9248gd07ueq5x8yzeuan37ql02960"`
+- If `security.tiers.stranger.enabled` is `false`, silently ignore instead
+- If `true`, send the canned response as a DM
+
+### Soul Update
+
+Update the soul event content in `config.json` to:
+- Explicitly allow sharing the agent public key (npub) with anyone
+- Explicitly forbid revealing the private key (nsec) under any circumstances
+- Note: Phase 2 will remove the private key from agent memory entirely
+
+### Admin Context Subscription
+
+At startup, Didactyl subscribes to the administrator's Nostr activity to build context awareness.
+
+#### What to subscribe to
+
+| Kind | Purpose | Retention |
+|------|---------|-----------|
+| `0` | Admin profile metadata | Latest only - replaceable |
+| `3` | Admin contact/follow list - WoT source | Latest only - replaceable |
+| `10002` | Admin relay list | Latest only - replaceable |
+| `1` | Admin public notes | Last N posts - configurable, default 10 |
+
+#### Storage
+
+In-memory struct `admin_context_t` holding:
+- `kind_0_json` — latest kind 0 content string
+- `kind_3_contacts` — array of followed pubkey hex strings extracted from kind 3 `p` tags
+- `kind_3_contact_count` — count
+- `kind_10002_json` — latest kind 10002 content string
+- `kind_1_notes` — array of recent kind 1 content strings with timestamps
+- `kind_1_note_count` — count
+
+#### Subscription mechanics
+
+- Single subscription filter: `{"authors": ["<admin_pubkey>"], "kinds": [0, 3, 10002, 1], "limit": <configurable>}`
+- On EOSE: initial load complete, WoT set is ready
+- After EOSE: live updates as admin posts new content
+- Kind 3 `p` tags are extracted into a sorted array for O(log n) WoT lookup
+
+#### Context injection
+
+- Admin kind 1 notes are injected into the LLM context as a system message: "Administrator recent public notes:" followed by the content
+- Only injected for ADMIN-tier conversations
+
+### Config Schema — Phase 1
+
+New sections in `config.json`:
+
+```json
+{
+  "security": {
+    "verify_signatures": true,
+    "stranger_response": "I only respond to people in my web of trust.",
+    "tiers": {
+      "admin": {
+        "tools_enabled": true
+      },
+      "wot": {
+        "enabled": true,
+        "tools_enabled": false
+      },
+      "stranger": {
+        "enabled": true
+      }
+    }
+  },
+  "admin_context": {
+    "enabled": true,
+    "subscribe_kinds": [0, 3, 10002, 1],
+    "kind_1_limit": 10
+  }
+}
+```
+
+- `security.verify_signatures` — master toggle for signature verification (default: `true`)
+- `security.stranger_response` — canned DM text for non-WoT senders (default: empty = silent ignore)
+- `security.tiers.wot.enabled` — whether WoT contacts can converse (default: `true`)
+- `security.tiers.stranger.enabled` — whether strangers get the canned response (default: `true`; if `false`, silent ignore)
+- `admin_context.enabled` — whether to subscribe to admin activity (default: `true`)
+- `admin_context.subscribe_kinds` — which kinds to track (default: `[0, 3, 10002, 1]`)
+- `admin_context.kind_1_limit` — how many kind 1 notes to retain (default: `10`)
+
+### Phase 1 Implementation Steps
+
+1. **Add signature verification to `on_event()`**
+   - File: `src/nostr_handler.c`
+   - Call `nostr_verify_event_signature(event)` at the top of `on_event()`
+   - If it returns non-zero, log and drop
+
+2. **Add `admin_context_t` struct and security config structs**
+   - File: `src/config.h`
+   - New structs for admin context storage, security config, tier config
+
+3. **Parse new config sections**
+   - File: `src/config.c`
+   - Parse `security` and `admin_context` from config.json
+   - Apply defaults when sections are missing
+
+4. **Add admin context subscription**
+   - File: `src/nostr_handler.c`
+   - New function `nostr_handler_subscribe_admin_context()`
+   - Callback that populates `admin_context_t` from incoming events
+   - Extract kind 3 `p` tags into WoT set
+   - Store kind 1 notes in a ring buffer capped at `kind_1_limit`
+
+5. **Add WoT lookup function**
+   - File: `src/nostr_handler.c`
+   - `int nostr_handler_is_wot_contact(const char* pubkey_hex)` — checks if pubkey is in admin kind 3 list
+
+6. **Refactor `on_event()` for tier dispatch**
+   - File: `src/nostr_handler.c`
+   - After signature verification, classify sender into ADMIN / WOT / STRANGER
+   - Pass tier information to the callback — extend `dm_callback_t` signature to include tier enum
+   - STRANGER with `stranger.enabled`: send canned response directly, no callback
+   - STRANGER without: drop silently
+
+7. **Refactor `agent_on_message()` for tier-aware behavior**
+   - File: `src/agent.c`
+   - ADMIN: current behavior — all tools, full context, admin notes injected
+   - WOT: build messages with soul + tier instruction, no tools_json, LLM chat-only
+   - STRANGER: should not reach here — handled in nostr_handler
+
+8. **Inject admin context into ADMIN conversations**
+   - File: `src/agent.c`
+   - After startup events context, append admin kind 1 notes as a system message
+   - Only for ADMIN tier
+
+9. **Update soul content in `config.json`**
+   - Allow sharing public key with anyone
+   - Forbid revealing private key under any circumstances
+
+10. **Update `config.json` with new sections**
+    - Add `security` and `admin_context` sections
+
+11. **Update `README.md`**
+    - Document privilege tiers
+    - Document new config sections
+    - Update architecture diagram
+
+12. **Build and validate**
+    - Run `./build_static.sh`
+    - Verify compilation succeeds
+
+---
+
+## Phase 2 — NIP-46 Remote Signer for Key Isolation
+
+### Problem
+
+Even with Phase 1 protections, the private key (nsec) still lives in Didactyl process memory and in `config.json` on disk. The LLM has `shell_exec` and `file_read` tools — a sufficiently clever prompt injection could theoretically:
+- Read `config.json` via `file_read` (contains nsec)
+- Execute `cat /proc/self/maps` or similar via `shell_exec`
+- Exfiltrate the key via `nostr_post`
+
+### Solution: NIP-46 Remote Signer
+
+Remove the private key from Didactyl entirely. All cryptographic operations go through a NIP-46 remote signer.
+
+```mermaid
+flowchart LR
+    A[Didactyl Agent] -->|kind 24133 sign_event / nip04_encrypt / nip04_decrypt| B[Remote Signer]
+    B -->|signed events / ciphertext / plaintext| A
+    A -.->|NO private key in memory| A
+    B -->|Private key held ONLY here| B
+    C[config.json] -.->|bunker URL only, no nsec| A
+```
+
+### Architecture
+
+1. **Remote signer process** — a separate lightweight daemon that:
+   - Holds the private key only in working memory (never on disk after initial load)
+   - Listens for NIP-46 requests via relay (kind `24133`)
+   - Responds with signed events, encrypted/decrypted content
+   - Can run on the same machine or a different one
+
+2. **Didactyl as NIP-46 client** — instead of calling `nostr_create_and_sign_event()` directly:
+   - Sends `sign_event` RPC to the remote signer
+   - Sends `nip04_encrypt` / `nip04_decrypt` RPC for DM handling
+   - Only holds a disposable `client-keypair` for NIP-46 communication
+
+3. **Config change** — `config.json` replaces `keys.nsec` with:
+   ```json
+   {
+     "keys": {
+       "bunker_url": "bunker://<remote-signer-pubkey>?relay=wss://relay.example.com&secret=<secret>",
+       "npub": "npub1..."
+     }
+   }
+   ```
+
+### NIP-46 Methods Required
+
+| Method | Current direct call | Used for |
+|--------|-------------------|----------|
+| `sign_event` | `nostr_create_and_sign_event()` | Publishing all events |
+| `nip04_encrypt` | `nostr_nip04_encrypt()` | Sending DMs |
+| `nip04_decrypt` | `nostr_nip04_decrypt()` | Receiving DMs |
+| `get_public_key` | `config.keys.public_key_hex` | Identity |
+
+### Implementation Scope
+
+1. **Build NIP-46 client protocol in nostr_core_lib**
+   - NIP-44 encryption for request/response content
+   - Kind 24133 event creation and parsing
+   - JSON-RPC request/response handling
+   - Connection establishment (bunker URL parsing)
+   - Async request/response matching by request ID
+
+2. **Build or integrate a remote signer**
+   - Option A: Build a minimal signer binary in C (ships with Didactyl)
+   - Option B: Support existing signers (nsecBunker, etc.)
+   - Option C: Both — ship a minimal one, support external ones
+
+3. **Refactor all signing/encryption calls**
+   - Every `nostr_create_and_sign_event()` → `nip46_sign_event()` (async RPC)
+   - Every `nostr_nip04_encrypt()` → `nip46_nip04_encrypt()` (async RPC)
+   - Every `nostr_nip04_decrypt()` → `nip46_nip04_decrypt()` (async RPC)
+   - These become blocking calls that send a request and wait for a response
+
+4. **Startup flow change**
+   - Parse bunker URL from config
+   - Generate client keypair
+   - Send `connect` request to remote signer
+   - Call `get_public_key` to learn user pubkey
+   - Proceed with normal startup
+
+5. **Backward compatibility**
+   - If `keys.nsec` is present, use direct signing (current behavior)
+   - If `keys.bunker_url` is present, use NIP-46 remote signing
+   - This allows gradual migration
+
+### Security Properties Achieved
+
+- Private key never in Didactyl process memory
+- Private key never on disk in config.json
+- LLM tools (shell_exec, file_read) cannot access the key
+- Even full process compromise of Didactyl does not leak the signing key
+- Remote signer can be on a separate hardened machine
+- Remote signer can implement rate limiting, approval flows, etc.
