Coexistence lab

The live lab activated all ten roster plugins together and embedded each isolated Core Six page in an iframe. All 10 of 10 iframes loaded.

Runtime signature

• Resources: 58
• JavaScript: 33 files / 306,191 bytes
• CSS: 14 files / 147,851 bytes
• Total transfer: 662,213 bytes
• Top-document DOM nodes: 215
• jQuery observed: no
• Plugin top-level admin menus: all ten identified among 24 items

Findings

• Activation completed without a recorded activation issue.
• H5P requested its content directory URL and received HTTP 403, although its iframe and native Question Set still rendered.
• Tutor LMS custom ecommerce initially queried a nonexistent multisite-prefixed users table. Selecting Tutor’s supported free ecommerce engine removed the fatal, and provisioning now applies that setting.
• Tutor’s admin upgrader also emitted a foreign-key database error while attempting its order item metadata table; the dashboard remained usable.
• The measured frontend pass recorded no page errors or request failures, and the immediate PHP debug-log diff contained no new frontend finding.

These catches are part of the result rather than exceptions hidden from the ranking. See the individual dossiers and raw evidence.
