<b>SOP: Smartlink change rollback</b>

Purpose: undo a bad routing edit in under two minutes instead of debugging live traffic.

☐ Step 1 — Before any edit, export the current rule set and weights to a dated file.
☐ Step 2 — Make one change at a time. Bundled edits make rollback guesswork.
☐ Step 3 — Watch EPC and fallback-rate for 30 minutes post-change. A fallback spike means a rule broke.
☐ Step 4 — If EPC drops more than 20% or fallback exceeds 10%, restore the exported set immediately.
☐ Step 5 — Only then diagnose what the change broke, on a copy, not on live traffic.
☐ Step 6 — Log every change with timestamp so you can correlate metric shifts to edits.

Keep the last five exports. The break you didn't notice today shows up in tomorrow's numbers.
