Can anyone think of a way for the edict of merlin to do what it does without tampering with peoples minds?
If by “tampering” you mean just “permanently modifying”, the Source of Magic (TM) could just watch wizards’ minds(1) to detect when they’re writing in sufficient detail(2) high-level(3) spell descriptions, and enchant the written artifact.(4)
(1:) I can’t think of a way it would act the way it does—i.e., trigger wand-less and wordless spells, as well as accidental magic—without reading wizards’ minds at all times (or tampering with their minds at birth), anyway, at least not while following Harry’s genetic marker theory.
(2:) It needs to act only when the description tells you what to do, not what it does. Presumably it lets a historian describe what wondrous feats Merlin did as long as he didn’t describe how the spell was cast.
(3:) I’m really curious how that works. It’s clear that some spells are “harder” to cast, and some are “more powerful” than others (not sure if the two are perfectly correlated), but AFAIK it’s never described what that really means, except for trivial things like complex wand patterns and not-really-helpful stuff like “only first-year student magic level”.
(4:) Basilisks turn you to stone when you look at them, the Mirror-of-I-can’t-remember-who-it-was showed you what you wanted when you looked at it, so it’s clear that magic effects can be triggered by looking at the magical item.
(4b:) Exactly what “written artifact” means would be kind of hard to figure out. If it also applies to non-textual artifacts—sound recordings, encoding a description with smells and colors, planting a row of trees of two species to spell the description in ASCII—then it’s really complicated.
It might just look at what people intend to do, but then it would be vulnerable to complicated attacks like encrypting the description with a key, giving the encrypted text to a scribe who knows the described spell but doesn’t know the key nor what the encrypted text is, and asking them to write the encrypted text, then writing the key separately—or even unintentional recordings. Then again, we have no evidence it isn’t vulnerable to all that, there would have been little opportunity centuries ago. Harry’s pouch does respond to languages neither the caster nor the user knows, but then again it doesn’t answer for simple encodings like “1+1” for “2”...
