Objective planning: Kernel Interface (#2)

[JaimeStill]

Summary

• Transition from Objective Objective: Kernel Core Loop #1 (Kernel Core Loop, complete) to Objective Objective: Kernel Interface #2 (Kernel Interface)
• Decompose Objective Objective: Kernel Interface #2 into 6 sub-issues with dependency graph
• Update _project/phase.md — mark Objective Objective: Kernel Core Loop #1 complete, Objective Objective: Kernel Interface #2 in progress
• Update _project/objective.md — replace with Objective Objective: Kernel Interface #2 scope, sub-issues, architecture decisions

Sub-Issues Created

#	Title	Dependencies
#23	Streaming tools protocol	—
#24	Agent registry	—
#25	Kernel observer	—
#26	Multi-session kernel	#23, #24, #25
#27	HTTP API with SSE streaming	#26
#28	Server entry point	#27

Collateral Updates

• Objective Objective: Kernel Interface #2 issue title updated to "Objective: Kernel Interface"
• Objective Objective: Kernel Interface #2 issue body updated with expanded scope (pure HTTP + SSE, agent registry, multi-session, observer)
• Objective Objective: Local Development Mode #4 issue body updated — observer absorbs logger concern
• Objective Objective: Kernel Core Loop #1 closed (5/5 sub-issues complete)
• All sub-issues linked to parent, assigned Task type, added to project board with Phase 1
