clawbot 4e268b9118 Bring README.md in line with the modes and the schema (closes #119)
check / check (push) Waiting to run
The MODE section described a query-only command. It now covers channel
and user mode queries and changes on the HTTP API and the IRC listener,
the letters each accepts, what is broadcast, and the error numerics.
The schema section now lists every table and column in
001_initial.sql.

The rest of the README was checked against the code, and each statement
the code contradicts is corrected: polled numerics carry their name in
command and their number in code; command errors are numerics with HTTP
200, not 404 or 409; the broker is keyed by session; WAL is never on; an
empty IRC_LISTEN_ADDR does not disable the listener; and the IRC
listener handles modes, INVITE, +s and +H more narrowly.

clawbot 0f2e63d0cc Add the tier 3 utility IRC commands (closes #87)
check / check (push) Waiting to run
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.

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

clawbotanduser 24362966e0 feat: move schema_migrations into 000_bootstrap.sql (#95)
check / check (push) Successful in 5s
## Summary

- Moves schema_migrations table creation from inline Go code into internal/db/schema/000_bootstrap.sql
- Bootstrap SQL is executed directly before the migration loop (which starts from 001+)
- Go code does zero INSERTs for the bootstrap — 000_bootstrap.sql handles the INSERT OR IGNORE for version 0
- loadMigrations() skips 000.sql so it is not processed by the normal migration loop

Follows the sneak/pixa pattern.

closes #91

## Test plan

- [x] All existing tests pass (make test in Docker)
- [x] Linter passes (make lint)
- [x] Docker build succeeds (docker build --no-cache .)
- [x] Existing databases with schema_migrations table work (CREATE TABLE IF NOT EXISTS + INSERT OR IGNORE are idempotent)

946f208ac2 feat: implement IRC numerics batch 2 — connection registration, channel ops, user queries (#59)
check / check (push) Successful in 5s
## Summary

Implements the remaining important/commonly-used IRC numeric reply codes, as requested in [issue #52](sneak/chat#52).

### Connection Registration (001-005)
- **002 RPL_YOURHOST** — "Your host is <server>, running version <ver>"
- **003 RPL_CREATED** — "This server was created <date>"
- **004 RPL_MYINFO** — "<server> <version> <usermodes> <chanmodes>"
- **005 RPL_ISUPPORT** — CHANTYPES=#, NICKLEN=32, CHANMODES, NETWORK=neoirc, CASEMAPPING=ascii

All sent automatically after RPL_WELCOME during session creation/login.

### Server Statistics (251-255)
- **251 RPL_LUSERCLIENT** — user count
- **252 RPL_LUSEROP** — operator count
- **254 RPL_LUSERCHANNELS** — channel count
- **255 RPL_LUSERME** — local client count

Sent during connection registration and available via LUSERS command.

### Channel Operations
- **MODE command** — query channel modes (324 RPL_CHANNELMODEIS + 329 RPL_CREATIONTIME) and user modes (221 RPL_UMODEIS)
- **NAMES command** — query channel member list (reuses 353/366)
- **LIST command** — list all channels with member counts (322 RPL_LIST + 323 end)

### User Queries
- **WHOIS command** — 311 RPL_WHOISUSER, 312 RPL_WHOISSERVER, 319 RPL_WHOISCHANNELS, 318 RPL_ENDOFWHOIS
- **WHO command** — 352 RPL_WHOREPLY, 315 RPL_ENDOFWHO

### Database Additions
- `GetChannelCount()` — total channel count for LUSERS
- `ListAllChannelsWithCounts()` — channels with member counts for LIST
- `GetChannelCreatedAt()` — channel creation time for RPL_CREATIONTIME
- `GetSessionCreatedAt()` — session creation time

### Other Changes
- Added `StartTime` to `Globals` struct for RPL_CREATED
- Updated README with comprehensive documentation of all new commands and numerics
- Updated roadmap to reflect implemented features

`docker build .` passes (lint, tests, build all green).
