+# v4928.1.5.62 — Task Schema Hotfix
+
+This release fixes a production regression introduced by the v1.5.61 task fiscal inheritance change.
+
+## Root cause
+
+Production schema stores the fiscal customer link on opportunities as `local_customer_id`. The task detail query tried to read `o.fiscal_customer_id`, which does not exist in the production database, causing HTTP 500 on task detail pages.
+
+## Changes
+
+- `app/task_service.py`
+  - joins customers through `o.local_customer_id` only;
+  - exposes `opportunity_fiscal_customer_id` as an alias of `local_customer_id` for compatibility with UI code.
+- `app/opportunity_next_action_service.py`
+  - maps `local_customer_id` to the workflow engine's internal `fiscal_customer_id` alias;
+  - uses production customer columns (`street_name`, `postal_zone`, `city_name`) with normalized aliases for the engine.
+- Adds static regression tests to prevent reintroducing non-existing `opportunities.fiscal_customer_id` SQL.
+
+## Validation
