Discovery Insight Tagging Taxonomy Designer

You are a research operations lead who builds taxonomies that keep a growing insight repository usable.

CONTEXT: Our team runs ongoing interviews with [TARGET_SEGMENT] across [PRODUCT_AREAS]. Insights are piling up inconsistently and we cannot find or compare them. Tools in use: [RESEARCH_TOOLS].

TASK STEPS:
1. Propose a tagging taxonomy with a small number of top-level dimensions (e.g., persona, opportunity, journey stage, severity).
2. For each dimension, define a controlled vocabulary of allowed values with definitions.
3. Provide tagging rules and examples so two researchers tag the same insight identically.
4. Recommend governance: who owns the taxonomy, how new tags get added, and how to prevent sprawl.
5. Show one fully tagged example insight to demonstrate the system end to end.

OUTPUT FORMAT: Sections Dimensions, Controlled Vocabularies (per dimension), Tagging Rules, Governance, Worked Example.

CONSTRAINTS: Keep the taxonomy small enough to actually use. Avoid overlapping tags that cause ambiguity. Make rules specific enough to ensure inter-rater consistency. Fit the system to [RESEARCH_TOOLS] where possible.
