Methodology & Bibliography

How this site is sourced, which canonical primary sources back its claims, and how the data is refreshed.

Data last refreshed: 2026-05-08. Next scheduled refresh: Q4 2026, or sooner on regulator/vendor trigger (A2A spec revision; IETF AAuth RFC progression; NIST CAISI publication; Microsoft Entra Agent ID major update).

Sourcing rule

Every claim has at least one direct quote or paraphrase from a canonical primary source — vendor docs, standards bodies, regulator publications, peer-reviewed papers, or an analyst publication where the analyst is the primary source for the framing. Wikipedia and secondary blogs are never the primary citation. When a topic is contested, both positions are carried with attributed flags.

Freshness flags

• Foundational — original peer-reviewed papers (e.g., Mitchell et al. 2019 Model Cards). Refreshed only if substantively revised.
• In force — current binding regulator text or in-effect specifications, with the in-force date.
• Emerging 2024–2026 — terms or specs that entered mainstream discourse recently and are still evolving.
• Contested — entries with named, meaningful disagreement in the field; we carry both positions.

Research sprint

This site was first promoted to tier-1 enrichment on 2026-05-08. The full audit trail — sources surveyed, quotable lines captured, stale claims retired, open questions for the next sprint — lives in the repository at raw/research-notes.md. The sprint covered the eight research dimensions (R1 vendor-canonical updates, R2 regulator activity, R3 analyst output, R4 academic frontier, R5 competitor moves, R6 search-intent signals, R7 fresh quotables, R8 counter-narratives) per the build-authority-property workflow.

Refresh cadence

• Default: bi-annual full review (per the SKILL Part G mechanic table for pillar mini-sites).
• Trigger refresh: A2A spec revision (v1.1+); IETF AAuth RFC progression; NIST CAISI publication; Microsoft Entra Agent ID major update; new Linux Foundation founding-member announcement; major marketplace launch (Salesforce / Google / AWS / Microsoft).
• Citation rot check: quarterly URL-liveness scan over every cited source.
