That's a separate validation effort and not strictly needed to call Approach C "working" — every code path it touches is independently exercised by the preview test. + +## Known gap (defer) + +**install.sh tenants need an env-patch mechanism for imageTag to actually take effect.** + +For CCP-provisioned tenants (`isRegistered=false`): CCP renders the full `.env` including `IMAGE_TAG=`. Compose's `${IMAGE_TAG:-latest}` picks it up. Works. + +For install.sh tenants (`isRegistered=true`): CCP filters `.env` out of the rendered set (no secrets in DB to render against). The tenant's existing `.env` stays, including its existing `IMAGE_TAG` value. **CCP's `Instance.imageTag` is persisted in CCP DB but doesn't reach the tenant's compose.** + +To close this gap, add: +- Agent endpoint `POST /instance/:slug/env/patch { vars: { IMAGE_TAG: 'v2.10.3' } }` that does in-place key=value patching on the tenant's existing `.env`. +- In `runReleaseUpgrade`, for isRegistered tenants, call this between writeFiles and composePull. + +Not a blocker for Approach C in CCP-provisioned tenants — those work end-to-end.
