fix: reduce reconnect backoff to 1s flat

Exponential backoff up to 300s made no sense with rotating Tor exits where each reconnect gets a fresh IP. Single 1s delay is sufficient. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
feat: DCC stripping in both directions to prevent IP leaks

 Set server password to `mypassword` in the network settings.

+## Client TLS
+
+The bouncer can accept TLS-encrypted connections from IRC clients. This
+encrypts the password and all traffic between your client and the bouncer.
+
+### Setup
+
+```toml
+[bouncer]
+client_tls = true
+```
+
+On first start with `client_tls = true`, the bouncer auto-generates a
+self-signed EC P-256 certificate at `{data_dir}/bouncer.pem` (10-year validity).
+The certificate fingerprint is logged at startup.
+
+### Custom Certificate
+
+To use your own certificate (e.g. from Let's Encrypt):
+
+```toml
+[bouncer]
+client_tls = true
+client_tls_cert = "/path/to/fullchain.pem"
+client_tls_key = "/path/to/privkey.pem"
+```
+
+If the cert and key are in the same PEM file, set only `client_tls_cert`.
+
+### Client Examples
+
+**irssi:**
+```
+/connect -tls -tls_verify no -password mypassword 127.0.0.1 6667
+```
+
+**weechat:**
+```
+/server add bouncer 127.0.0.1/6667 -password=mypassword -ssl -ssl_verify=0
+/connect bouncer
+```
+
+**hexchat:**
+
+Enable "Use SSL for all the servers on this network" and accept the
+self-signed certificate.
+
+### Verify with openssl
+
+```bash
+openssl s_client -connect 127.0.0.1:6667
+```

 Stored commands: `PRIVMSG`, `NOTICE`, `TOPIC`, `KICK`, `MODE`.

+## PING Watchdog
+
+The bouncer sends periodic PING messages to detect stale server connections
+(socket open but no data flowing). If no data is received within the configured
+interval, a PING is sent. If the server doesn't respond within the timeout,
+the connection is dropped and a reconnect is scheduled.
+
+```toml
+[bouncer]
+ping_interval = 120   # seconds of silence before sending PING
+ping_timeout = 30     # seconds to wait for PONG after PING
+```
+
+The watchdog starts automatically when a network enters the READY state.
+Any received data (not just PONG) resets the timer.
+
+## IRCv3 server-time
+
+The bouncer requests the `server-time` IRCv3 capability on every connection.
+When enabled by the server, timestamps on incoming messages are preserved and
+forwarded to clients. When the server does not provide a timestamp, the bouncer
+injects one using the current UTC time.
+
+Backlog replay also includes timestamps from when messages were originally
+stored, so clients that support `server-time` see accurate times on replayed
+messages.
+
+No client configuration is needed -- timestamps appear automatically if the
+client supports IRCv3 message tags.
+
+## Push Notifications
+
+When no IRC clients are connected to the bouncer, highlights and private
+messages can trigger push notifications via [ntfy](https://ntfy.sh) or a
+generic webhook.
+
+### Setup
+
+```toml
+[bouncer]
+notify_url = "https://ntfy.sh/my-bouncer-topic"
+notify_on_highlight = true    # mentions of your nick in channels
+notify_on_privmsg = true      # private messages
+notify_cooldown = 60          # min seconds between notifications
+notify_proxy = false          # route notifications through SOCKS5
+```
+
+### ntfy Example
+
+```toml
+notify_url = "https://ntfy.sh/my-secret-topic"
+```
+
+Install the ntfy app on your phone and subscribe to the topic. Notifications
+include the sender, target, and message text.
+
+### Generic Webhook
+
+Any URL that does not contain `ntfy` in the hostname is treated as a generic
+webhook. The bouncer POSTs JSON:
+
+```json
+{
+  "network": "libera",
+  "sender": "user",
+  "target": "#channel",
+  "text": "hey mynick, check this out"
+}
+```
+
+### Behavior
+
+- Notifications only fire when **no clients** are attached
+- The cooldown prevents notification floods (one per `notify_cooldown` seconds)
+- When `notify_proxy = true`, notification requests are routed through the
+  configured SOCKS5 proxy
+

+## Background Account Farming
+
+The bouncer can automatically grow a pool of verified NickServ accounts across
+all configured networks. Primary connections stay active with SASL-authenticated
+identities while ephemeral connections register new nicks in the background.
+
+### Setup
+
+```toml
+[bouncer]
+farm_enabled = true
+farm_interval = 3600       # seconds between attempts per network
+farm_max_accounts = 10     # max verified accounts per network
+```
+
+### How It Works
+
+1. A sweep loop runs every 60 seconds (after an initial 60s stabilization delay)
+2. For each NickServ-enabled network, it checks:
+   - Is there already an active farming attempt? (skip)
+   - Has the cooldown (`farm_interval`) elapsed since the last attempt? (skip)
+   - Are there already `farm_max_accounts` verified accounts? (skip)
+3. If eligible, an ephemeral connection is spawned with a random nick
+4. The ephemeral goes through the full registration lifecycle: REGISTER, email
+   verification (or captcha), and credential storage
+5. Credentials are saved under the real network name, not the ephemeral's
+   internal `_farm_` prefix
+6. Each ephemeral has a 15-minute deadline before being terminated
+7. Ephemeral connections are invisible to IRC clients (no status broadcasts,
+   no channel joins)
+
+### Commands
+
+| Command | What it does |
+|---------|-------------|
+| `FARM` | Global overview: enabled/disabled, interval, per-network stats |
+| `FARM <network>` | Network stats + triggers an immediate registration attempt |
+| `ACCOUNTS` | List all stored accounts with verified/pending counts |
+| `ACCOUNTS <network>` | Accounts for a specific network |
+
+### Configuration Reference
+
+```toml
+[bouncer]
+farm_enabled = false       # enable background registration (default: off)
+farm_interval = 3600       # seconds between attempts per network
+farm_max_accounts = 10     # stop farming when this many verified accounts exist
+```
+
+## Channel Keys
+
+Channels with mode `+k` require a key to join. Configure keys in TOML:
+
+```toml
+[networks.libera]
+channels = ["#secret", "#public"]
+channel_keys = { "#secret" = "hunter2" }
+```
+
+Keys are used automatically during autojoin and KICK rejoin. To add a keyed
+channel at runtime:
+
+```
+/msg *bouncer AUTOJOIN libera +#secret hunter2
+```
+
+Removing a channel also clears its key:
+
+```
+/msg *bouncer AUTOJOIN libera -#secret
+```
+
+## DCC Stripping
+
+DCC requests (`DCC SEND`, `DCC CHAT`) embed the sender's real IP address in the
+protocol payload. The bouncer strips all DCC and non-ACTION CTCP messages in
+both directions:
+
+- **Inbound** (server to client): silently dropped, logged as warning
+- **Outbound** (client to server): blocked before reaching the network
+
+ACTION (`/me`) is preserved. This is a hard security boundary -- there is no
+config toggle to disable it.
+
+## Hot Reload
+
+The bouncer reloads its config file on `SIGHUP` or via the `REHASH` command.
+Both use the same logic: re-read TOML, diff networks (add/remove/reconnect),
+and update mutable fields (channels, channel_keys, nick, password).
+
+### SIGHUP
+
+```bash
+kill -HUP $(pidof bouncer)
+```
+
+Results are logged (no client connection needed). Useful for headless
+operation (systemd, containers).
+
+### REHASH command
+
+```
+/msg *bouncer REHASH
+```
+
+Results are sent back as NOTICE messages.
+
+### What changes on reload
+
+| Field | Effect |
+|-------|--------|
+| Network host/port/tls/proxy | Network reconnected |
+| channels, channel_keys, nick, password | Updated in-place |
+| notify_url, notify_cooldown, etc. | Notifier recreated |
+| farm_enabled, farm_interval, etc. | Farm started/stopped |
+| bind, port, password, client_tls | Warning logged (restart required) |
+
+## Systemd
+
+The bouncer ships with a systemd user service file. See [INSTALL.md](INSTALL.md)
+for setup. Key operations:
+
+```bash
+systemctl --user start bouncer        # start
+systemctl --user stop bouncer         # stop
+systemctl --user reload bouncer       # hot reload (SIGHUP)
+journalctl --user -u bouncer -f       # follow logs
+```
+
+The service restarts automatically on failure (`RestartSec=10`).
+
 ## Stopping

 Press `Ctrl+C` or send `SIGTERM`. The bouncer shuts down gracefully, closing

Author	SHA1	Message	Date
user	1ea72011b7	fix: reduce reconnect backoff to 1s flat Exponential backoff up to 300s made no sense with rotating Tor exits where each reconnect gets a fresh IP. Single 1s delay is sufficient. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-02-21 19:39:30 +01:00
user	0064e52fee	feat: DCC stripping in both directions to prevent IP leaks Block all non-ACTION CTCP/DCC from client-to-server (outbound) and add security logging when inbound CTCP/DCC is stripped. Hard boundary with no config toggle -- DCC exposes the client's real IP which defeats the stealth proxy architecture. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-02-21 19:30:44 +01:00
user	f4f3132b6b	feat: systemd user service file for headless deployment Hardened unit with ProtectSystem/ProtectHome, auto-restart on failure, and ExecReload for SIGHUP hot config reload. Docs updated with setup, management, and enable-linger instructions. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-02-21 19:25:36 +01:00
user	638f12dbb3	fix: resolve all pre-existing ruff lint errors Fix E501 line-too-long in backlog.py, network.py, test_network.py. Fix F541 f-string-without-placeholders in network.py. Fix I001 unsorted imports in network.py. Remove unused datetime import in test_cert.py (F401). Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-02-21 19:13:34 +01:00
user	2ab5f95476	feat: SIGHUP hot reload for headless config updates Add signal handler that calls rehash() on SIGHUP, logging results instead of sending to a client. Useful for systemd and container environments where no IRC client is attached. Update docs with channel key config, hot reload section, and roadmap checkoffs. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-02-21 19:03:35 +01:00
user	c11bd5555a	feat: channel key support for +k channels Add channel_keys dict to NetworkConfig for storing per-channel keys. Keys are used in KICK rejoin, passed via AUTOJOIN +#channel key syntax, supported in ADDNETWORK channel_keys= parameter, and propagated through REHASH. Extract rehash() as reusable async function for SIGHUP reuse. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-02-21 19:03:23 +01:00
user	bf4a589fc5	feat: client-side TLS for encrypted client connections Accept TLS-encrypted connections from IRC clients. Auto-generates a self-signed EC P-256 listener certificate (bouncer.pem) when no custom cert is provided. Remove CTCP response items from roadmap (stealth by design -- router already suppresses all CTCP except ACTION). Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-02-21 18:47:20 +01:00
user	bfcebad6dd	feat: background account farming with ephemeral connections Add RegistrationManager that periodically spawns ephemeral Network connections to register new NickServ accounts across all configured networks. Ephemeral connections reuse the existing registration lifecycle (random nick, email verification, captcha solving) with two new Network parameters: cred_network (redirect credential storage to the real network name) and ephemeral (suppress status broadcasts, skip SASL/IDENTIFY, go straight to REGISTER). - backlog: add count_verified_creds() query - config: farm_enabled, farm_interval, farm_max_accounts - network: cred_network/ephemeral params, credential ref redirection - farm: new module with sweep loop, per-network cooldown, stats - router: farm lifecycle integration, farm property - commands: FARM (status/trigger) and ACCOUNTS (list stored creds) - tests: 14 farm tests + 5 ephemeral/cred_network network tests Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-02-21 18:17:22 +01:00
user	ae8de25b27	fix: verify success completion signal + cross-session verify_url restore _on_verify_success() was missing _nickserv_complete() call, causing _go_ready() to hang at _nickserv_done.wait() when registration completed immediately (no email verification needed). get_pending_registration() was not returning verify_url from the DB, so _resume_pending_verification() never restored self._verify_url -- breaking cross-session captcha resume for OFTC-style networks. Four regression tests added. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-02-21 17:55:33 +01:00
user	0d762ced49	feat: PING watchdog, IRCv3 server-time, push notifications PING watchdog sends PING after configurable silence interval and disconnects on timeout, detecting stale connections that TCP alone misses. IRCv3 server-time capability is requested on every connection; timestamps are injected on dispatch and backlog replay for clients that support message tags. Push notifications via ntfy or generic webhook fire on highlights and PMs when no clients are attached, with configurable cooldown and optional SOCKS5 routing.
