+# DEC-003 — ActivityDefinition Copy vs Reference
+
+**Status:** accepted
+**Date:** 2026-06-18
+**Owner:** Bernd
+**Blocks:** LOOP-WP-0001 T04, activity-core sync workflow
+
+---
+
+## Question
+
+How should coulomb-loop ActivityDefinitions relate to kaizen-agentic supplier templates?
+
+## Context
+
+ADR-002 assigns ActivityDefinition **copies** to the customer repo. activity-core
+syncs from its own catalog path (ACT-ADR-002). Two sync models are possible.
+
+## Options
+
+### A — Customer-owned copies (recommended)
+
+Copy supplier templates into `coulomb-loop/activity-definitions/`. activity-core
+syncs from coulomb-loop path (or vendored subtree). Customer edits cron, labels,
+roster params without supplier release.
+
+| Pros | Cons |
+|------|------|
+| Coulomb controls cadence ramp (hourly bootstrap) | Drift from supplier templates |
+| Matches ADR-002 | Manual merge when supplier updates templates |
+
+### B — Supplier catalog only
+
+Reference supplier repo path; activity-core syncs `kaizen-agentic/docs/integrations/activity-definitions/`.
+
+| Pros | Cons |
+|------|------|
+| Single source of truth | Hourly bootstrap crons don't match supplier weekly defaults |
+| Less copy maintenance | Customer cannot tune without supplier PR |
+
+### C — Hybrid manifest
+
+`coulomb-loop/activity-definitions/manifest.yaml` lists supplier source + local overrides (cron, enabled, labels). activity-core merge tool applies patches.
+
+| Pros | Cons |
+|------|------|
+| Drift-aware automation | Requires new activity-core or coulomb-loop tooling |
+| Best long-term for multiple customers | Not available today |
+
+## Recommendation
+
+**Option A** for bootstrap (minimal tooling). Track **Option C** in KAIZEN-WP-0008
+as supplier playbook enhancement for second customer.
+
+## Decision record
+
+| Field | Value |
+|-------|-------|
+| Chosen option | **A** — customer-owned copies |
+| Decided by | Bernd Worsch |
+| Decided at | 2026-06-18 |
+| Notes | Option C hybrid manifest tracked in KAIZEN-WP-0008 T08 |
+
+## On approval
+
+Proceed with LOOP-WP-0001 T04 copy step; document merge procedure in `loops/kaizen-stack/supplier-notes.md`.
