Owner Routing Process

Step-by-step procedure for determining the most likely owner/team for each bug cluster using strict 6-level precedence with staleness detection and override memory.

Instructions

Step 1: Check Overrides First

For each cluster, check if a routing_override exists from a prior run:

• If found: use the override (confidence 1.0, source "routing_override"), skip precedence lookup
• Log the override application to audit

Step 2: Query Sources in Precedence Order

For each cluster without an override, query sources strictly in order:

Stop at the first level that returns a valid team or assignee.

Step 3: Apply Confidence Modifiers

Multiply each result's confidence by the precedence modifier from routing_config.

Step 4: Detect Staleness

Flag any routing signal older than the staleness threshold (default 30 days):

• Mark the result as stale with the number of days
• Reduce confidence accordingly
• Stale signals are still usable but should be noted in output

Step 5: Build Recommendation

Using lib.buildRoutingRecommendation():

• Rank valid results by level (lowest level = highest priority)
• Set top_recommendation to the best result
• If no valid results: set uncertainty=true with reason "Routing: uncertain — no routing signals available. Manual assignment required."
