- founding a guild: fourteen opcodes, eight goldens (four mutation-checked), twelve engine globals, `GuildRegistrarFrame` and `PetitionFrame` — `CMSG_PETITION_BUY` is a 72-byte frame the server reads two fields of and drops in silence if short, `allowedGender` is the family's one u16, a signature is a 12-byte stride not 8, and `MSG_PETITION_DECLINE` writes the charter guid and reads the decliner's — same width, opposite meaning
- two sessions, not one: the registrar is an NPC session (closed by walking away — its show event is one of the fourteen callers of the interact latch, so the registrar turns to face you) and the charter is bound to an item guid you carry across the city; right-clicking a charter in your bags opens it, keyed on template flag `0x2000` (item 5863 has no on-use spell and no quest, so every existing item-use arm declined it)
- the byte carve came back and rescored six named guesses — three confirmed, two corrected, one refuted: `PETITION_SHOW` is deferred until every signer name has resolved (the window never paints blank rows), `ClosePetition` on somebody else's charter sends `MSG_PETITION_DECLINE` ("sends nothing" had been chosen on principle and was wrong half the time), and founding a guild is silent — no `ERR_GUILD_FOUNDER_S`, the reference emits no text at all; the four success ids go to chat and the five refusals to the red error frame, three paraphrased strings are now the shipped ones (a sweep asserts all fifteen), and the `npc` unit token had never been fed — the registrar's name banner was blank; `WOW_PROBE_CHARTER=1` drives gossip → buy → open → rename → destroy live, 10/10
