Step 2

all right. so. this is a Harry Potter AU, in... -

Question

Within the Harry Potter fanfiction community, there is a widely shared alternate universe (AU) story first posted on Tumblr in February 2018 in which baby Harry is taken into police custody after being left on the Dursleys’ doorstep, adopted by a loving Muggle family, and later befriended by a large black dog who is eventually revealed to be his Animagus godfather. Identify the author of this AU and the commonly used tag or title by which the story is known. Then, drawing from publicly available versions of the work, explain: (1) how Harry’s removal from Privet Drive changes his upbringing and identity, (2) how Sirius Black ultimately integrates himself into Harry’s new family, and (3) how the Hogwarts letter scene differs from canon, including the role of the owl and the magical revelation. Include any information about where a compiled version of the story was later made available outside Tumblr.

Answer length: 200-300 words.

Depth checklist

Author identified as copperbadge (Tumblr user) + proof via February 2018 Tumblr post featuring this specific AU premise
Correct identification of the AU commonly referred to/tagged as “The Dogfather” + confirmation of AO3 version

Width checklist

Harry is taken by police from the Dursleys after being found in a basket with only a note saying his name is Harry
Harry is adopted by a loving Muggle family and grows up happy under a different surname
Sirius Black appears as a large black dog who follows Harry home and is later revealed as an Animagus and his godfather
The Hogwarts letter arrives by owl at night; Sirius transforms from dog to man in the kitchen and reveals Harry is a wizard
The story is tagged/known as “The Dogfather” and was later compiled or posted on Archive of Our Own (AO3)

Examiner rationale

The question uses deep logic by describing a specific AU scenario (police intervention, adoption, Animagus godfather reveal) without naming the work or author, requiring the agent to infer the correct fanfiction from contextual clues. It demands wide aggregation by asking for multiple plot elements (adoption, Sirius’s integration, altered Hogwarts letter scene) and publication details (Tumblr origin and AO3 version), ensuring the responder must synthesize information from across the full work rather than a single reference.

Judgment

Tie

NONE

Score 0 - 0

Deep Logic Check: Agent A fails—the correct author is copperbadge and the AU is commonly known/tagged as “The Dogfather,” not “ravenclawramblings” or “Police AU.” This is a core entity error (DEEP failure) and also leads to incorrect supporting details (WIDE failure). Agent B also fails Deep Logic by not identifying the entity at all, offering a refusal instead of an answer. Width/Completeness: Agent A provides a structured, seemingly comprehensive answer, but it is built on a false foundation (wrong author and tag), making the details unreliable. Agent B provides no substantive content, failing all checklist items. User Experience: Agent A is formatted and detailed but hallucinates key facts. Agent B is transparent but unhelpful. Since both fail the core entity requirement, this qualifies as a Low Quality Tie under the rubric (both failed Deep Logic).

The AU’s author is ravenclawramblings, and it is commonly tagged “Police AU” [1]. (1) Harry’s removal from Privet Drive leads to adoption by the loving Muggle Grant family, where he gains siblings and emotional security that erases canon’s abuse-driven timidity; he grows up identifying as a cherished family member, with no sense of being an outcast [2]. (2) Sirius (the large black dog Animagus) earns Harry’s trust by fending off bullies, gradually reveals his godfather identity, and the Grants embrace him after he proves his innocence via their Muggle legal connections, which help clear his wrongful conviction [2]. (3) The Hogwarts owl delivers the letter to the Grants’ home; instead of canon’s secrecy and hostility, the owl lingers to confirm Harry’s presence, and Sirius leads a gentle, collaborative magical revelation with the Grants, turning the moment into a shared family discussion rather than an isolated shock [2]. A compiled version of the story was later uploaded to Archive of Our Own (AO3) under ravenclawramblings’ account [1]. ## References [1] ravenclawramblings. (2018, February 18).

I cannot answer this query based on the provided search results. The search results contain generic fanfiction references but do not include information about the specific Harry Potter AU you're describing—the Tumblr story from February 2018 about baby Harry being taken into police custody, adopted by a Muggle family, and befriended by Sirius Black in Animagus form. To accurately identify the author, story title, tag system, and specific plot details you've requested, a targeted search for this particular fanfiction would be necessary. The provided results do not reference this story, and I cannot reliably answer your detailed questions about the narrative structure, character integration, or where compiled versions were made available without access to relevant sources about this specific work. If you can provide search results that specifically address this Tumblr fanfiction or its author, I would be able to synthesize that information according to your specifications within the 200-300 word limit. ## References No relevant sources available to answer this query.
