Crucible of Erratic Energies (264507) never procs for Subtlety Rogue due to incorrect proc_flags

[craned70]

Describe the bug

Crucible of Erratic Energies (item 264507) never procs for melee specs. The driver spell (1272091) has
proc_flags=0x00015500, which contains no melee proc types. When the proc callback is initialized, it registers only
for those proc types, meaning melee actions never trigger the callback at all. The SX_ONLY_PROC_FROM_CLASS_ABILITIES
check inside trigger() is never reached for melee actions because the dispatch filter eliminates them first.

Expected behavior

The trinket should proc from class abilities for melee specs. In-game testing confirms it does proc live from specific
class abilities but not from auto-attacks. This suggests the live engine may handle
SX_ONLY_PROC_FROM_CLASS_ABILITIES differently than simc — possibly by broadening proc eligibility beyond what
proc_flags alone would allow — but the exact live behavior is not fully confirmed.

To Reproduce

Sim any melee spec with Crucible of Erratic Energies equipped. Enable debug logging and search for voidlust

log.txt

The original bug report diagnosis (proc_flags are wrong) is incorrect. wago.tools confirms ProcTypeMask=0x00015500
on spell 1272091. simc is reading the correct game data.

• simc does implement SX_ONLY_PROC_FROM_CLASS_ABILITIES (spell_attribute index 415, maps to SPELL_ATTR12 bit 31 =
  0x80000000). The check exists in dbc_proc_callback_t::trigger() at line 210, but is never reached for melee actions.
• Several class modules hardcode allow_class_ability_procs = true on auto-attacks (warrior, rogue, monk, dk, dh,
  druid, shaman, paladin, hunter). If the registration issue is fixed, these would cause auto-attacks to incorrectly
  proc Crucible — live testing shows auto-attacks do not proc it.

Hello, I had a brief look into this and logged a short combat trying different things: WCL link

The idea was the following:

1. First only auto attack a dummy with no poisons
   Result: no procs
2. Only auto the dummy with just a lethal poison
   Result: no procs
3. Only auto the dummy with just a nonlethal poison
   Result: no procs
4. Only special attack the dummy with no autos/poisons
   Result: procs seemingly after Backstab, Shadowstrike, Secret Technique second clone hit

The procs are seemingly attributed to those abilities because the aura gain for Voidlust appears to have either identical (in the case of Backstab and SecTect second clone hit), or very close timestamp to their damage (Shadowstrike). There might be more abilities that proc it, but from my limited testing it was only those 3 (and in the case of SecTec only the second clone hit).

Can the proc be from a buff gain, debuff application, or healing event?

From the looks of it, not anything visible in the logs. There are big gaps between such events and procs.

The only debuff applied was Fazed and you can find procs seconds after Fazed being applied

There are procs between no recent healing events

There are procs between no recent buff gains

Conversely, you find multiple procs close or on the damage timestamp

Edit:
Here is an additional log with no healing talents at all and no SnD running ever, just plain backstabs where it still procs: Log

Likely will be fixed by #11253

The trinket was hotfixed to have proper proc flags. Future items with similar improper flags should exhibit correct behavior.
