clawbot 129d87d578 Show an IRC listener user what their session sends from other clients (closes #179)
check / check (push) Waiting to run
The IRC listener's relay dropped every line sent under the connection's own nick, so a user on the web client and an IRC client at once never saw on IRC what they did from the web client. The relay now drops nothing by nick. Instead the fan-out skips only the sending client's own queue: the IRC listener passes its own client, whose handler already wrote the echo, and the HTTP API skips none. Channel messages and PARTs now reach the sender's other clients, so an HTTP client gets its own PART event; neoirc-cli ignores it, as it already shows its own part. README.md names the commands covered.

Judgement call: a PRIVMSG or NOTICE sent on an IRC connection is not echoed back to it, as in IRC.

clawbot e7e408c93e Resolve IRC client hostnames off the accept loop (closes #156)
check / check (push) Waiting to run
acceptLoop called newConn, which did the reverse DNS lookup, with its
three-second timeout, before the loop could accept the next
connection, so one client whose address had no answering reverse DNS
held up every other IRC connect. serve now does the lookup at its
start, on the connection's own goroutine, and the accept loop only
accepts.

The server keeps the lookup function in a field, as it does the ping
times, so that a test can give it one that blocks. The new test
checks that a second client registers while the first one's lookup
has not returned.

clawbot 497514d3df Wait for IRC listener cleanup and HTTP shutdown on stop (closes #159)
check / check (push) Waiting to run
Stopping the server returned before the IRC listener's connections had
run their cleanup, and the database closed under them, so their
sessions, clients and channel memberships stayed and their nicks stayed
taken after a restart.

The IRC listener's stop now waits up to five seconds for every
connection's cleanup, which now runs on a context that stopping does
not cancel. The HTTP server's stop hook now runs Shutdown itself and
waits for it; httpServer is set before serving starts, and the server's
own signal watcher, which raced fx's stop hooks, is gone.

clawbot e3d01454b3 PING a quiet IRC listener client before closing it (closes #155)
check / check (push) Canceled after 0s
serve closed a connection after five minutes with nothing read and never
sent a PING, so a quiet registered client lost its session. It now sends
PING :<server> after pingInterval with nothing read, and closes the
connection when nothing is read within pongDeadline after that. Every
line read starts both waits again. readTimeout is removed.

Unregistered connections are sent the PING too, so a PONG before
registration is now ignored instead of answered with ERR_NOTREGISTERED.

clawbot 5100b9a665 Remove the relay's broker wait channel after each tick (closes #151)
check / check (push) Canceled after 0s
The IRC relay registers a broker wait channel on each pass of its
loop, and when the 100 ms ticker fired instead of a notification it
looped without removing that channel. An idle IRC listener connection
added ten channels a second to the broker, and all but the last stayed
after the connection closed. The ticker case now removes its channel,
as the HTTP long-poll does after its timer.

Broker.ListenerCount returns how many wait channels a user holds, so
the test can check that an idle connection holds at most one, and
none after it closes.

clawbot 0f2e63d0cc Add the tier 3 utility IRC commands (closes #87)
check / check (push) Canceled after 0s
USERHOST, VERSION, ADMIN, INFO, TIME, KILL and WALLOPS work on the
HTTP API and on the IRC listener. The USERHOST reply, the VERSION,
ADMIN and INFO text, KILL and WALLOPS are each one service function
that both transports call. User mode +w selects who receives WALLOPS.
MODE on your own nick queries or changes your user modes through one
parser on both transports: the whole mode string is checked before
anything is stored, and both flags are stored in one transaction. KILL
closes the victim's IRC connection after sending it KILL and ERROR,
without the operator waiting on it. The sessions table gains
is_wallops in 001_initial.sql, as the pre-1.0 rule in REPO_POLICIES.md
asks.

clawbotandclawbot f829f9e3da Change module path to sneak.berlin/go/neoirc (#99)
check / check (push) Failing after 1m39s
Changes the Go module path from `git.eeqj.de/sneak/neoirc` to `sneak.berlin/go/neoirc`.

All occurrences updated:
- `go.mod` module directive
- All Go import paths across 35 `.go` files (107 import statements)
- All JSON schema `$id` URIs across 30 `.json` files in `schema/`

No functional changes — this is a pure rename of the module path.

`docker build .` passes clean (formatting, linting, all tests, binary build).

closes #98

0250f14fea feat: add traditional IRC wire protocol listener (closes #89) (#94)
check / check (push) Successful in 5s
## Summary

Adds a backward-compatible IRC wire protocol listener (RFC 1459/2812) that allows standard IRC clients (irssi, weechat, hexchat, etc.) to connect directly via TCP.

## Changes

### New package: `internal/ircserver/`

- **`parser.go`** — IRC wire protocol message parser and formatter
- **`server.go`** — TCP listener with Fx lifecycle integration
- **`conn.go`** — Per-connection handler with registration flow, PING/PONG, welcome burst
- **`commands.go`** — All IRC command handlers (JOIN, PART, PRIVMSG, MODE, TOPIC, KICK, WHOIS, etc.)
- **`relay.go`** — Message relay goroutine that delivers queued messages to IRC clients in wire format

### Modified files

- **`internal/config/config.go`** — Added `IRC_LISTEN_ADDR` environment variable
- **`internal/handlers/handlers.go`** — Broker is now injected via Fx (shared with IRC server)
- **`cmd/neoircd/main.go`** — Registered `broker.New`, `ircserver.New` as Fx providers
- **`pkg/irc/commands.go`** — Added `CmdUser` and `CmdInvite` constants
- **`README.md`** — Added IRC Protocol Listener documentation section

### Tests

- Parser unit tests (table-driven, round-trip verification)
- Integration tests: registration, PING/PONG, JOIN, PART, PRIVMSG (channel + DM), NICK change, duplicate nick rejection, LIST, WHOIS, QUIT, TOPIC, MODE, WHO, LUSERS, MOTD, AWAY, PASS, CAP negotiation, unknown commands, pre-registration errors
- Benchmarks for parser and formatter

## Key Design Decisions

- **Optional**: Listener is only started when `IRC_LISTEN_ADDR` is set
- **Shared infrastructure**: Same DB, broker, and session system as HTTP API
- **Full bridge**: IRC ↔ HTTP messages are interoperable
- **No schema changes**: Reuses existing tables
- **Broker as Fx dependency**: Extracted from handlers to be shared

## Supported Commands

Connection: NICK, USER, PASS, QUIT, PING/PONG, CAP
Channels: JOIN, PART, MODE, TOPIC, NAMES, LIST, KICK, INVITE
Messaging: PRIVMSG, NOTICE
Info: WHO, WHOIS, LUSERS, MOTD, AWAY, USERHOST
Operator: OPER
