Focus on distinguish content in code that is temporary (work in progress, "wip" prefix) and content in code that is permanent.
Content considered temporary to be removed after migration has been done.
Work in progress.

Note that commit is twelfth step in introducing audit tables.

Focus on clean-up.
Work in progress.

Note that commit is tenth step in introducing audit tables.

Major switch for functionality as non-audit related tables
no longer used for create, update, delete operations.

Focus on services.
Work in progress.

Note that commit is ninth step in introducing audit tables.

Remove latest attribute.

Focus on bean elements.
Work in progress.

Note that commit is eighth step in introducing audit tables.

Refactor handling of structures and remove endpoints for structures to approve, cancel, reject.
Process of structure entry proposed to be created, updated, deleted by user and
processed (approved, rejected) by administrator or cancelled by user is no more.
Instead, administrator is to create, update, delete structure entry.

Note that commit is first step in removing status as query parameter.

Update integration tests.

Former fields name and description are merged into description field (database) through script.
Name field removed from database script and code in model, repository, service, beans.

Update conversion of structures data from one format to another for name field of structures (Excel to json, json to Excel).
Update templates.
Update Swagger UI.
Update documentation.

Add and update integration tests.

Particular attention to be paid to
- merge in migration database script and use of functions nullif and concat_ws
- verification of migration

Add field for ordering of structures to allow better UI experience.
Add field in database script and code including model, repository, service, beans.
Add option to sort by field but not to query by field.

Update conversion of structures data from one format to another for ordering of structures (Excel to json, json to Excel).
Update templates.
Update Swagger UI.
Update documentation.

Add and update integration tests.

Return one or two structure elements for history of structures.
Add missing parameter in validation of input parameters for reading names.
Update unit and integration tests.

Update schemas and json handling for structures with content more closely suited for operations.
Update api, controller, service, validation, integration tests.

Mnemonic path is ambiguous if considered in past.
Therefore not show mnemonic path for history of structure.
Show mnemonic path if latest and approved status.

Refactor to reduce complexity and have uniform handling of enums.

Ensure maximum one entry is latest for any given uuid.
Update integration tests.

Assignments should not be redundant
Collection sizes and array length comparisons should make sense
Conditionally executed code should be reachable
Empty arrays and collections should be returned instead of null
Local variables should not shadow class fields
Null pointers should not be dereferenced
Pattern Matching for "instanceof" operator should be used instead of simple "instanceof" + cast
Return of boolean expressions should not be wrapped into an "if-then-else" statement
Sections of code should not be commented out
"switch" statements should have at least 3 "case" clauses
Two branches in a conditional structure should not have exactly the same implementation

Declarations should use Java collection interfaces such as "List" rather than specific implementation classes such as "LinkedList"
Empty statements should be removed
JUnit assertTrue/assertFalse should be simplified to the corresponding dedicated assertion
JUnit5 test classes and methods should have default package visibility
Methods and field names should not be the same or differ only by capitalization
Nested "enum"s should not be declared static

Rename package for beans.
Remove unused beans.

Change mnemonic path for structure elements to
system group, system, system + subsystem
