🦡 Ledger Entry: PASSAGE_NOT_FOUND

So the corridor really was a dead end. No prefect's shortcut, no hidden knock on brick, no Room of Requirement waiting behind that door — the passage you followed simply doesn't exist, and never has.

In plainer terms: a 404 is what happens when your browser sends an owl to an address, and the address isn't on the map. Not "delivery refused" (that's a 403 — something behind the Restricted Section rope). Not "the owl collapsed mid-flight" (that's a 500 — something broke in the castle's plumbing on our end). A 404 just means: this room was never built, this corridor never carved, or the floor plan changed and nobody updated your copy of the map.

🕯️ How a passage goes missing

• 🜁 A link was carved with a typo in it — one letter off, and the castle has no idea what you mean.
• 🜁 The room got renovated and moved to a new wing, and the old sign was never taken down.
• 🜁 You're working from an out-of-date Marauder's Map — a bookmark or search result pointing at a corridor that's since been sealed.
• 🜁 Someone simply never built that wing at all.

None of this costs your house any points. It just means: wrong staircase. Head back down and try again.
