Neo Angband: Borg v0.4.0

0.4.0 - 2026-08-20

Borg can see danger. plugin.ts built Borg with no resolvers, so every seam fell back to its conservative default, and the one that mattered was the facts resolver: zero blows and zero spell frequency meant borg_danger reported no threat, so nothing was ever worth fleeing from. It now binds the host’s monster race registry, which is what borg_danger needs to reason about a monster it is tracking rather than one it can currently see.
A mod’s monsters are dangerous on the same terms as core’s. Binding happens after mods compose, so a modded creature is an ordinary monster race at a real index and the resolver never asks where it came from. A test pins that, so the behaviour cannot be narrowed to core content later by accident.
On a host with no registry the Borg still plays and writes “playing blind” to its log. A Borg playing badly and a Borg handed no monster data look identical from outside and have completely different causes, so it says which it is.

Three of the four resolver seams are still on their defaults: no activations, never in a shop, and no power credited for an item whose value it has not been told. The README now names which seams are live and which are not.

A game carrying ctx.registries, which is Neo Angband 0.23.0 or newer. On anything older the mod loads and plays without danger vision rather than refusing to load, because a mod that can still do most of its job should not lock a player out of the rest of it.
