Filed per owner directive on uwe.admin/fewo-webapp#462: Batch D (auth/permissions) of the temporal-entity-to-Repository migration belongs here in oatpp-authkit, not in fewo-webapp, since these are all auth/security primitives that any oatpp-authkit-consumer benefits from.
Tables in scope
Four temporal entities currently living in fewo-webapp's
sql/schema.sql:users— application user account (idINTEGER autoinc, no entity_id; not currently composite-FK-shaped becauseidis the join key)role_templates— field-level permission templates (already on composite-FK schema as of fewo-webapp#459 PR 7)user_property_permissions— per-property access controluser_group_permissions— per-property-set access controlWhy it lives here
Per
webapp-template/docs/STACK.md's decision table:The User entity itself is the canonical target audience for
Repository<T>because every oatpp-authkit consumer manages users. Currently fewo-webapp'sUserDbis the onlyuserstable consumer, but the moment a derivative project (webapp-template, palibu, etc.) needs user management, havingRepository<UserDto>shipped from oatpp-authkit means zero re-implementation.Similarly for
role_templatesand the two permission tables — those are the canonical authkit data model for field-level + property-scoped permissions. fewo-webapp consumes them throughRoleTemplateDbandPropertyAccessChecker; if any other project ever needs the same shape, it'll want it from authkit.Cross-repo migration shape
This is non-trivial because it crosses two repo boundaries:
usersschema +UserDbfrom fewo-webapp → oatpp-authkit, exposing them as a header library callersFetchContent. fewo-webapp's existingusersrows must stay valid (live--allow-plaintextdeploys keep their user table).Repository<UserDto>+ composite-FK temporal schema for users (currentlyUserDtousesInt32 id, not entity_id — the user model itself isn't temporal yet). This raises a design question:valid_until = now()rather thanis_active = 0?role_templates+ permissions tables similarly. These are already temporal (composite-FK as of fewo-webapp#459 PR 7), so the migration is more mechanical — just relocation + Repository wiring.sql/schema.sqland DTOs, depend on oatpp-authkit's pinned tag for them. Existing data tables remain bit-identical; only the source-of-truth for the schema moves.Sequencing
Probably one PR per table to keep diffs reviewable:

The schema-shipping convention above is the only piece not directly covered by the issue body. Check one:
const std::stringschema in C++ headers (proposed above). Pro: header-only, no install paths; Con: schema is C++ string literals, harder to read/lint as SQL..sqlfiles installed alongside headers (e.g.share/oatpp-authkit/sql/role_templates.sql). Pro: SQL stays SQL; Con: requires install-path resolution at runtime, conflicts with header-only model.schema.sql, authkit only ships headers/Repository — the schema text stays the same in fewo, only the C++ binding moves. Pro: simplest; Con: any consumer of authkit (palibu, webapp-template, etc.) has to copy the SQL into its ownschema.sqlinstead of getting it for free.PRs 2-4 (
user_property_permissions,user_group_permissions,users-with-temporal-shape) follow the same pattern once Convention is locked.Convention D — Decorator-built schema + Atlas-managed migrations + runtime
verify()Adding this as a fourth option after offline discussion. Supersedes the A/B/C decision in the prior comment — D solves the underlying problem (keeping decorator stack and schema in sync) instead of just answering "where do CREATE TABLE strings live."
How it works
1. Decorators declare column contributions, not SQL. Each decorator in the stack exposes an
inline static constexpr ColumnSpec kAddedColumns[]:ConcreteXxxRepository declares its base columns, TemporalRepository declares the temporal triple, ScopeGuardRepository declares scope columns, etc.
2.
SchemaBuildercomposes the stack into a single CREATE. At app boot against an empty DB (or Atlas dev DB), the builder walks the stack once, unions allkAddedColumnsper table, emits oneCREATE TABLE persons (…all columns from all layers…). No ALTER chains — neither historical (those live in Atlas migrations) nor stack-imperative (composition is declarative).3. Atlas owns evolution. CI runs
SchemaBuilderagainst a throwaway dev DB → Atlas inspects it → that becomes the desired state.atlas migrate diffcompares against the live prod DBs current state and emits a versioned migration SQL file. Atlass diff engine handles SQLite-specific table-rebuild migrations (the very pain that drove fewo-webapp#459 PR 7) automatically.4. Runtime
verify()asserts coverage. On startup, each decorator queriesPRAGMA table_info(or equivalent) and fails loud if its required columns are missing. Guarantees code can never run against an under-migrated DB.Lifecycle
SchemaBuilder::create(executor)(one CREATE per table)atlas migrate diffproduces new migration SQLatlas migrate applyruns new migrationsSchemaContract::verify(executor)asserts columnsWhy D over A/B/C
const std::string) and B (.sqlfiles) answer the wrong question: they decide where CREATE strings live but dont address the root issue — the decorator stack and the schema can drift silently. C (fewo keeps schema, authkit only ships C++) has the same drift risk and forces every consumer to copy SQL.TemporalRepositoryto a stack automatically contributesentity_id/valid_from/valid_until; the schema follows the code. Atlass declarative diff handles all evolution including the SQLite-specific rebuilds.Tradeoffs of D
verify()is a CI gate.SchemaBuilderin oatpp-authkit before PR 1 of the migration can land. Probably worth its own preceding PR (call it PR 0).schema.hclbecomes a generated artifact in the repo, not hand-edited.Updated decision needed

Adds a PR 0 (SchemaBuilder+SchemaContract) before PR 1.If D is accepted, the PR sequence becomes:
SchemaBuilder+SchemaContract::verifyinfrastructure in oatpp-authkit; one trivial table (e.g. an example) demonstrates the round-trip; Atlas wired into oatpp-authkits CI.role_templatesmigrated using the new convention.user_property_permissions,user_group_permissions,users-with-temporal-shape.Before kicking off PR 0 I re-read the existing decorator code and need to flag a contradiction with my Convention D writeup that the owner should resolve.
What already exists in oatpp-authkit (from authkit#12, already shipped)
Each decorator already exposes a static migration kit:
A runner
applyDecoratorMigrations<TemporalRepository<...>, AuditLogRepository<...>, ...>(table, probe, exec)walks every decoratorsPREREQ+RESHAPE_STEPSagainst a{table}placeholder, idempotent viadetectSqlprobes.This is the exact "decorator-driven, runtime-applied, idempotent ALTER chain" model I sold against in the prior comment when defining D. The infrastructure is already deployed. fewo-webapp likely already calls it (havent verified yet — would need to grep
applyDecoratorMigrations).How this changes Convention D
The "decorator code stays simple — only knows how to create, never evolve" framing was wrong. The existing kit is imperative ALTER chains with detect-probes, which is exactly what your "stack-composition ALTER" question was probing. I called that "fragile" — but the existing kit makes it idempotent and testable, which neutralises most of the fragility.
Three possible reconciliations:
D-revised — keep the existing
PREREQ+RESHAPE_STEPSas the source of truth. CI runsapplyDecoratorMigrationsagainst an empty DB, Atlas inspects the result as desired state, generates migrations against prod. Atlas owns evolution between deploy generations; the decorator kit owns evolution from empty to current. Smallest change. PR 0 collapses to "wire Atlas into oatpp-authkits CI" + a CI parity test that asserts re-runningapplyDecoratorMigrationsis a no-op (idempotency check). No new C++ infrastructure.D-strict — add a parallel declarative
kAddedColumnsper decorator, write a CI test that asserts parity betweenkAddedColumnsand whatRESHAPE_STEPSactually produces. Both layers exist;kAddedColumnsis the Atlas-facing surface. Costs: dual-write, drift risk. Benefit: Atlas can introspect schema without spinning up a SQLite DB.D-replace — deprecate
PREREQ+RESHAPE_STEPS, replace withkAddedColumns+SchemaBuilder::create. Costs: throws away working, deployed infrastructure; consumers (fewo) need to re-wire. Benefit: clean single model.My read: D-revised is the right call. The existing kit already does what we want at runtime; Atlas is added as an external schema-diff tool between deploys, not as a replacement for the decorator-local migration runner. I should not have proposed D as if oatpp-authkit were greenfield. Apologies for the noise.
If you confirm D-revised, PR 0 reduces to:
schema-snapshotworkflow that boots an empty SQLite, runsapplyDecoratorMigrations<…all kit decorators…>(...), captures the result viaatlas schema inspectinto a versionedschema.hclartifact).applyDecoratorMigrationsis idempotent (run twice, schema unchanged).docs/MIGRATIONS.md.PR 1 (role_templates relocation) then proceeds as previously described, just consuming the existing kit instead of a new one.
Pick D-revised / D-strict / D-replace.

Would benefit from owner ack on the temporalusersmigration shape before I dive in:usersis non-temporal (id INTEGER autoinc,is_activeflag for soft-delete). Option B converts to entity-per-row withentity_id/valid_from/valid_untiltriple, soft-delete viavalid_until = now().entity_id = id(or new UUID) andvalid_until = SENTINEL. Thats an Atlas-generated migration the deploy pipeline applies once.usernameAND temporal predicate. Login lookup becomesWHERE username=? AND valid_until > now(). Affects every auth path.Want me to proceed with PR 4 directly, or hold for the password-hash placement decision?
Please proceed with PR 4 and make password hashes temporal, too (create an issue to mediate the security impact - maybe by blanking the actual hash but still keep the history of when the passowrd was changed).
