[JacobStephens2]

Summary

Docs only: the decision for #103, from a grilling session. The code comes later, through the Spec and Tickets.

 RepairLoop: CI red on head
+  compare failed checks with the Base branch commit head merged in (by name)
+  red on both → Inherited failure, no Repair
+    Base branch moved?        → merge it in, go round again
+    Base fix allowed?         → Merge run into the Base branch, wait, go round again
+    otherwise                 → Failed run: "CI red on <check>, which also fails on <base> at <sha>; fix <base> first"
   red on head only → CI-fix Repair (as today)

• CONTEXT.md: adds Inherited failure and Base fix, mentions the Base fix in the User config entry, and rewords the example in Declined CI fix.
• docs/adr/0008-inherited-failures-fail-the-run.md: the decisions, the options we rejected, and the accepted trade-off (a different failure in the same check hides behind the Base branch's red).

Evidence

• Before: JacobStephens2/chart35#71 spent a Repair ($0.35, 51s) only to find that Verify also failed on main, then ended as a Declined CI fix.
  After (once implemented): two API calls detect the same thing, and the Run fails with fix main first, or a Base fix fixes main.

Merge Danger
