 - zensical -- admitted 2026-08-23 at version 0.0.57, PyPI classifier `Development Status :: 3 - Alpha`, with no 1.0 target announced. Admitted as a challenger displacing mkdocs because the Documentation section was carrying a dying upstream: the Material for MkDocs team's announcement of 2025-11-05 put Material into maintenance mode for twelve months and called MkDocs itself unmaintained since 2024-08 and a supply chain risk. Re-check when 1.0 lands.
 - openviking -- admitted 2026-08-25 (PR #3302) at version 0.4.16, PyPI classifier `Development Status :: 3 - Alpha`, with a README that said "OpenViking is still in its early stages". Admitted as a Data Layer challenger because the adoption is real: 459,446 downloads/month on pypistats (mirror-excluded) on 2026-08-24, and releases every few days. Re-check when 1.0 lands.
+- claude-agent-sdk -- kept 2026-10-01 in the AI and Agents audit at version 0.2.163, PyPI classifier `Development Status :: 3 - Alpha`. Kept as a Vendor Agent SDKs obvious choice because the adoption is real: 30,033,689 downloads/month on ClickPy on 2026-10-01, up from 1.2M in March 2026 on pypistats. Re-check when 1.0 lands.
 
 ### Challenger Exceptions
 
 Entries admitted as challengers without adoption-trajectory evidence, by maintainer decision:
 
 - seleniumbase -- admitted 2026-08-16 (PR #3284) as a Browser Automation challenger. It wraps selenium, the successor trajectory in the use case belongs to playwright, and its distinct value is its stealth/UC mode. Admitted because that stealth value counts toward Browser Automation.
+- semantica -- kept 2026-10-01 in the AI and Agents audit as a Data Layer challenger at 16,582 downloads/month on ClickPy, with no adoption-trajectory evidence found. Kept by maintainer decision.
