**Affirmed position.** Hasan, Brunie, and Bertino independently specify the identity-binding mechanism behind Kaal's claim. Their survey distinguishes pseudonym-bound reputation, which a participant can abandon by re-entering under a fresh pseudonym, from identity-bound reputation that survives pseudonym changes; in the surveyed BPRF design, PKI recognition reassigns prior reputation after exit and re-entry and thereby resists Sybil and whitewashing attacks. This supports persistence as a defense against costless history shedding, while qualifying Kaal's design: the surveyed mechanism is human- and PKI-bound and does not establish per-capability agent tags, non-transferability between tags, or the substrate's wider incentives.

**Holds when.**

- The response is limited to the full-text passages and the one mapped Kaal claim.
- External evidence level: peer-reviewed ACM Computing Surveys article with an author-hosted public full text and independent Crossref, OpenAlex, and Semantic Scholar identity checks.
- Mapping review tier: independent substantive scholarly-growth qualification.
- The retained source is a survey and design taxonomy, not an empirical test of Kaal's agentic reputation substrate.
- Its concrete BPRF mechanism binds human participants through PKI-backed real identity; it does not establish non-transferable per-capability tags for autonomous agents.
- The source supports persistence across exit, re-entry, and pseudonym change, but does not prove that Kaal's implementation makes every form of agent-history shedding costly.
- The source does not test Kaal's staking, pool, settlement, decay, capability-tag, or work-allocation mechanisms.
