 Vague tickets are not acceptable. Workers are not smart enough to look things up.
 
+### Include path rule (copy into every ticket verbatim)
+NASM is invoked from the `dos_port/` directory with `-I include/ -I .`.
+Include paths must use the **short bare name only** — no directory prefix:

+```nasm
+%include "gb_memmap.inc"   ; correct
+%include "gb_macros.inc"   ; correct
+
+%include "dos_port/include/gb_memmap.inc"   ; WRONG — breaks the build
+%include "include/gb_memmap.inc"            ; WRONG — breaks the build

+Paste this rule into every worker ticket so it is impossible to miss.

 ### Dispatch rules
 - Never assign two workers to the same output file simultaneously.
 - Only dispatch `simple`-category jobs. If a job turns out to require hardware

 - Do not add `%include` lines or Makefile rules — that is Integration Agent's job.
 - `call` instructions inside the translated function are expected and correct.
