Context

The planner must compare repository projections, LaunchDarkly resources, and the saved baseline.

What changes

• Plan descriptor-backed variations, tools, and skills.
• Enforce all-or-nothing mapped-field capability.
• Read and enforce sync settings for every kind.
• Keep unmapped server fields during pushes.
• Send pulls through checked source publication.
• Report deleted linked resources without recreation.

local projection + server projection + baseline -> one resource action

Design notes

• Conflict granularity is one resource.
• Capability checks include unchanged mapped fields.

Review focus

• Can one field sync when another field is read-only?
• Are directions checked before every write?

Verification

• make build
• go test ./...
• Repository lint
• Relevant race tests
