HC Contract: No Petri

A self-contained Hardcore challenge addon for WoW Classic Era that lets you sign a public, verifiable contract to never use Flask of Petrification — and then enforces it, broadcasts it, and shames you if you break it.

The pitch

Flask of Petrification (item 13511) is the classic "get out of jail free" card on Hardcore — turn to stone, drop aggro, survive anything. This addon lets you publicly opt out of using it, proves to other players that you really did, and makes it socially painful to cheat.

What it does

Blocks the flask

Wraps UseContainerItem, UseItemByName, CastSpellByID, CastSpellByName and hooks UseAction
Catches every path you could use to drink Petrification (item 13511, spells 17626 / 17624)
Pops a loud on-screen warning on each blocked attempt
Throttled chat announce ("X just tried to sip Petri but the contract holds")

Detects violations (in case the block fails)

Listens to UNIT_SPELLCAST_SUCCEEDED, COMBAT_LOG_EVENT_UNFILTERED (SPELL_CAST_SUCCESS / SPELL_AURA_APPLIED), UNIT_AURA
A violation is permanent — no rollback, no /reload reset

Verifiable contract

Sign with a typed "I SWEAR" confirmation
Generates an 8-char verification token from playerGUID + signedAt via FNV-1a hash
Token, sign timestamp, character level at signing — all stored and shareable
Other players running the addon can verify you over addon comms

Public confession

On violation, fires a random fun message from a 7-template pool to:

/say
Guild
Party / raid
Every joined custom channel

Plus 4 throttled "blocked attempt" templates (guild + group only).

Peer verification

HCNOPETRI addon channel comm protocol (STATUS|v1|... and REQ|v1)
Auto-replies to !nopetri / !petri / !hcnopetri whispers
Online peer cache (90s window)
"Verify Players" scrollable list — click any peer to whisper-check them
Manual whisper-by-name field

Visual touchpoints
