-## Where the files differ from the HTTP API
-
-Where a schema file and the HTTP API disagree, the HTTP API is right:
-
-- `message.json` and the files in `numerics/` put the three-digit code in
-  `command`. They have no `code` field. The HTTP API puts the reply's name in
-  `command` and its number in `code`.
-- `message.json` allows an object as `body`. The HTTP API reads only arrays of
-  strings. A `PRIVMSG` with an object as `body` gets `ERR_NOTEXTTOSEND` (`412`).
-- `message.json` says `to` is a channel or a nick. A `WALLOPS` message has `*`
-  there.
-- `message.json` allows `meta` on every message. The HTTP API keeps a client's
-  `meta` only on a `PRIVMSG` or `NOTICE`.
-- `message.json` describes signature fields in `meta`. The server never checks a
-  signature.
-- `message.json` does not describe `meta.hashcash`. The HTTP API reads it in a
-  `PRIVMSG` to a channel with mode `+H`.
-- `JOIN.json` has no `body`. A client's `JOIN` can carry the channel key in
-  `body`. When a user joins, the `JOIN` event repeats the channel name in
-  `body`.
-- `JOIN.json` allows a channel name of any length. The server allows at most 63
-  characters after the `#`. It answers a longer name with `ERR_NOSUCHCHANNEL`
-  (`403`).
-- `KICK.json` puts the kicked nick in `params`. The HTTP API reads a client's
-  `KICK` from `body`: the nick, then an optional reason.
-- `MODE.json` puts the mode change in `params`. The HTTP API uses `body`
-  instead. A client sends the change and any value as separate strings, such as
-  `"+o"` and `"bob"`. In a `MODE` event, `body` holds the change as one string,
-  such as `"+o bob"`, or as two strings, such as `"+k"` and `"secret"`.
-- `NOTICE.json` allows `*` as `to`. The server answers a `NOTICE` to `*` with
-  `ERR_NOSUCHNICK` (`401`).
-- `NOTICE.json` has an example notice from the server to `*`. The server sends
-  no such notice.
-- `PING.json` and `PONG.json` describe a token that the `PONG` repeats. The HTTP
-  API ignores the `body` of a `PING`. Its answer is the HTTP response
-  `{"command": "PONG", "from": "<server name>"}`.
-- `PING.json` and `PONG.json` also describe messages between servers. The server
-  does not connect to other IRC servers.
-- `PUBKEY.json` describes a command the server does not have.
-- `QUIT.json` says that `QUIT` comes only from the server. A client can send it
-  too, to end its session. A client's `QUIT` can carry a reason in `body`.
-- `TOPIC.json` says a `TOPIC` without a `body` queries the topic. The HTTP API
-  answers such a `TOPIC` with `ERR_NEEDMOREPARAMS` (`461`).
-- `TOPIC.json` says an empty array clears the topic. The HTTP API answers `[]`
-  with `ERR_NEEDMOREPARAMS` (`461`). A `body` of `[""]` clears the topic.
-- `003.json` describes the server's creation date. The HTTP API sends the date
-  the server last started.
-- `004.json` has example mode lists. The HTTP API sends `ow` as the user modes
-  and `Hbiklmnostv` as the channel modes.
-- `322.json` says `LIST` gets one reply per channel. The server leaves out a
-  secret channel, one with mode `+s`, unless the user is on it.
-- `332.json` says `RPL_TOPIC` answers a `TOPIC` query. The HTTP API has no such
-  query. It sends `RPL_TOPIC` after a client sets the topic, and after a `JOIN`
-  to a channel that has one.
-- `353.json` says `body` lists nicks. The HTTP API lists `nick!user@host` in
-  place of each nick, such as `@op1!op1@host1`.
-- `353.json` says the first parameter marks a channel as public, private or
-  secret. The server always sends `=`, the mark for a public channel.
-- `376.json` gives the text as `End of /MOTD command`. The HTTP API adds a full
-  stop.
-- `401.json` gives the text as `No such nick/channel`. The server sends
-  `No such nick` in answer to a `PRIVMSG` or `NOTICE` to an unknown nick.
-- `433.json` has an example with `*` as `to`. The HTTP API sends `433` only in
-  answer to a `NICK`, with the user's nick as `to`.
-
-The HTTP API also accepts some messages that the files do not allow, such as a
-`JOIN` whose `to` has no `#`.
