The rules are being implemented in eo-phi-normalizer/test/eo/phi/rules/yegor.yaml:

• Rule 1
  • requires Add rule condition: presence/absence of an attribute #55, Add rule condition: (in)equality of attributes #56, Add rule feature: reference to global object bindings #57, Add rule feature: global vertex counter #58. Implemented in Rule feature: global counter #105
• Rule 2
  • requires Add rule condition: presence/absence of an attribute #55. Implemented in Add rule 2 to user-defined rules #112
• Rule 3
  • requires Add rule condition: presence/absence of an attribute #55
• Rule 4
  • requires Add rule feature: reference to global object bindings #57. Implemented in Global object matching #99
• Rule 5
  • ⚠️ implemented, but does not work properly (needs to be updated)
• Rule 6

I think all rules are now implemented (more or less faithfully). Now it is time to cover with tests and collect metrics.
