The default `http://localhost:3000` was a guess, and a guess that evaluates is worse than one that doesn't: the forge may run on a different host from the agents, and inside an agent's network namespace `localhost` reaches the agent itself, not the forge. hive-c0re renders this option into every agent's config from the host's `HIVE_FORGE_URL`, which `hive-c0re.nix` sets unconditionally, so nothing legitimate was relying on the default to be there. Also tightens the URL assertion, which accepted `""`. That escape hatch only existed because the default made the empty case unreachable; with the default gone, `""` is exactly what a caller supplies when they have nothing, so it now fails naming the option instead of silently building a config that talks to nowhere.

Base URL of the hyperhive-managed Forgejo. Used at container

boot by a oneshot systemd unit that calls
|
||
`tea login add --url <this> --token "$(cat $HYPERHIVE_STATE_DIR/forge-token)"`
|
||
(= `/agents/<name>/state/forge-token`) so the agent's claude can
|
||
shell out to `tea` without an extra auth dance. No-op when the
|
||
forge-token file is missing (i.e. hive-forge isn't running on
|
||
the host).
|
||
|
||
**Required, deliberately undefaulted.** hive-c0re renders it into
|
||
every agent's config from the host's `HIVE_FORGE_URL`, which
|
||
`hive-c0re.nix` sets unconditionally --- the forge is mandatory.
|
||
A loopback default would be a guess: the forge may run on a
|
||
different host from the agents, and inside an agent's network
|
||
namespace `localhost` reaches the agent, not the forge. An
|
||
unevaluatable config is better than one that builds and then

talks to the wrong machine.
