## Calls

From the extracted call graph of BC29 (graphify-al on the snapshot checkout): calls whose target is known from a declared type or an `Object::"Name"` argument. Interface dispatch and calls through events are not counted, so the list is not complete.

- [Codeunit 27 "Confirm Management"](../codeunit/27.md) (4 calls: `DeleteOrphanData → GetResponse`, `GetClearExtensionSchemaConfirmation → GetResponse`, `InstallExtensionWithConfirmDialog → GetResponse`, …)
- [Codeunit 1990 "Guided Experience"](../codeunit/1990.md) (1 call: `RunExtensionSetup → RunExtensionSetup`)

## Called by

Source: AL metadata extracted from the code (names, ids, signatures, properties); no code bodies (D10).

## Ask your agent

Procedure bodies are not stored here (D10). The call sections above are our own, per object, from the BC29 call graph. For a procedure body or the calls of one procedure, ask bc-code-atlas (external, by Stefan Maron, MIT; default corpus w1-28), which the bc-observatory plugin connects: `bcatlas_resolve_node(object_type: "codeunit", object_name: "Extension Installation Impl")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
