@@ -83,6 +83,10 @@ To read the game's own code (the way every patch target here was checked): `ilsp
   `is IEarlyTickableSingleton` and a wrapper would hide the type and change tick order. The reference to the wrapped service is weak. There is no Harmony patch in the hot loop, so
   nothing depends on the runtime not inlining a method, and a mod's own patch on the singleton is inside the measurement. Entity kinds are the one place a per-call patch is unavoidable
   (`TickableEntity.Tick`), so that is sampled.
+- **An entity is keyed by its kind, not by the name the tick system recorded** (`Profile.EntityKindOf`: the name up to its first space or `(`). The game renames a character loaded from a
+  save to `<template> <its own name>` before the tick system records it, and one made during play is `<template>(Clone)`, so up to 0.1.3 every loaded beaver was its own row and beavers
+  ranked far too low. `tools/perflog.py` (`entity_kind`) applies the same rule to older recordings, so compare lines old and new up: change both together. Its known-issue
+  note is printed only when a recording's entity rows really are split. No template name in the game or the installed mods contains a space or `(`; a modded template whose name did would be cut short.
 - **Saves are timed at three hooks** (`SaveQueued`, `SaveInstantlySkippingNameValidation`, `SaveWriter.WriteToSaveStream`); whichever is entered first owns the save (`SaveTracker`), and a save open for
   a minute is treated as abandoned (the game's save throws on an IO error and skips its postfix). BeaverBuddies defers the real save, so the `SaveWriter` hook is what times it.
 - **Nothing a session holds may outlive it**: `Session.Stop` clears `services` (its delegates reach the whole colony), the colony sampler, the mod resolver and the milestones, and `Session.Start`
