It defines protected content (code, URIs) that passes through untouched, conformance vectors, and implementations in several languages. For developers who sign or verify quoted text.

It recommends KERI with ACDCs for the attestations and states what the design does not deliver. For designers of privacy-preserving discovery and identity systems.

It argues that access control, action taxonomies and decentralized identity each keep only part of what the law of agency long held together, and draws on KERI and ACDC mechanisms for identity and verification. It is for architects of authorization for human and AI agents.

It explains the properties an alias must have, why the COIA naming convention helps, and why a proved binding must never be confused with a guessed one, pointing to entviz for comparing identifiers by eye.

It explains why organizational capacity (signing as citizen or as CEO) determines liability, why credentials have an affinity for a facet, and why opaque identifiers per facet need naming and visual verification tools.

It reports a curve rather than a single figure and states that all perceptual tolerances are modeled, not measured on people. It is for designers of human verification of keys and identifiers.

It sets out a channel-by-channel perceptual-entropy budget, distinguishes human-centric authentication visualization from machine perceptual hashing, and proposes a commit-and-reveal comparison walk, noting that the budget is an analytic estimate.

It compares the model with X.509, platform badges and STIR/SHAKEN and treats ACDCs as foundational evidence and SD-JWTs as derivative presentations.

It offers a lifecycle view (issuers, subjects, delegated signers), notes that multisignature identifiers can make governance inspectable, and ends with a richer set of questions for verifiers.

It credits Samuel M. Smith and the KERI community for emphasizing the distinction in the KERI, ACDC and did:webs specifications, and notes that authenticity can be computed while veracity rests on reputation.

Starting from losing a Signal account with a phone number, it argues that the benefit is not encryption but a portable trust context that can move across transports and devices without correlation, which the author calls self-sovereign security.

It sketches three techniques for what it calls reciprocal negotiated accountability: watermarks binding terms of service to shared data, provisional anonymity backed by verifiable encryption and escrow, and opt-in front-door decryption keys. For readers working on privacy, lawful access and self-sovereign identity. Daniel Hardman             1.1             Codecraft Papers (Daniel Hardman's paper archive) hardman-papers     1 0

It reframes the question around how expensive correlation is, who can perform it, when, how completely, and how much control the subject keeps, and argues that non-correlating credentials shift each of these in the holder's favor.

It examines the planes formed by each pair and argues that identity systems should model all three and then automate away what a context does not need. It predates KERI and draws its examples from self-sovereign identity (SSI), Sovrin and Hyperledger Indy.
