Features
- identity: Give an actor an identifier two implementations resolve (
a22853f)
Actor.id was an unconstrained string, and the repository spelled it five ways: role nouns, a first name, $USER. A provenance record is a block, so that string is hashed into block_id -- two spellings of one person are two names for one fact, and neither party fails. It is the divergence canonical serialization exists to prevent, arriving through a field nobody had canonicalized.
An identifier now takes one of two forms: an address, or a namespaced name. Lowercase ASCII, refused rather than normalized, because lowering one would mint a block_id the caller neither asked for nor can predict.
The check is deliberately asymmetric. Actor itself stays permissive, since every record ever written decodes through it and a validator on the type would strand every brain that predates the rule. Enforcement attaches where an identifier is chosen -- Brain.init and the request models -- where a caller can still be told what to choose instead.
The sandbox derived its actor from $USER, a name that resolves on one machine and nowhere else; the fallback is now namespaced under sandbox/ to say so.
