 ### P1: ZeroEntropy sunset — gbrain's default embedding provider dies Sept 4, 2026 (#2365)
 
 **What:** ZeroEntropy (acquired by Notion) shuts down September 4, 2026. gbrain's
-default embedding provider needs a migration path before then; gstack's
-setup-gbrain flow should stop recommending it and detect/warn existing installs.
+zeroentropyai recipe needs a migration path before then (the recipe + gateway
+shim are gbrain-internal — nothing in gstack ever recommended the provider).
 
-**Why:** Hard external deadline. After Sept 4, fresh setup-gbrain runs against the
-default provider fail, and existing brains stop embedding new pages silently.
+**Why:** Hard external deadline. After Sept 4, brains on the recipe stop
+embedding new pages silently.
 
-**Effort:** M (human ~2d, CC ~1h — mostly gbrain-side; gstack side is detect+warn).
+**Done (gstack side, v1.69.0.0):** wireup warns when ~/.gbrain/config.json names
+the recipe (fail-open grep), setup-gbrain provider comments say never to select
+it, USING_GBRAIN_WITH_GSTACK.md gained a troubleshooting entry (#2365).

 **Priority:** P1 (calendar-driven). **Depends on:** gbrain upstream provider support.

+- **#2163 legacy-slug checkpoint heal** — the gstack-slug refactor unified

 ## Completed

+**Priority:** P4 (was filed as slate-only — shipped with the whole drift class gated)
