📄 Description

Adds a field-note recording that AC4 Black Flag single-player has no reachable path to spawn a new, rendered character, plus the AnvilNext spawn system decoded:

appearance is stream/loader-only (the node model/child list is filled by the loader from a serialized descriptor; runtime-created nodes are empty shells)
crowd-life hosts ignore the record's character override; only mission/domino spawners render a chosen character and are mission-gated
the compiled-in debug/cheat 'Spawn Dude' system is dead in SP (the event type id occurs once, in its own descriptor; no listener)
the engine's class registry (vtable -> descriptor -> CRC32 name) decoded; the player-object array and its ten player slots
the engine's real set-world-transform path (component interface 0xD)
a byte-level RVA oracle that caught a wrong-address bug

Extends the existing AC4 notes (coop-ghost-avatar.md, reading-the-player-s-world-transform...). No game files or decompiled dumps.
