Preserve per-scheme and per-flow OAuth security contracts - #1050
OAuth schemes previously shared one requirement list and one flow scope inventory. Contracts with different per-scheme requirements or different OAuth flow inventories could be rejected or lose distinctions.
This change preserves each scheme's required scope or role names and each OAuth flow's exact scope names and descriptions through import, DSL evaluation, generated authentication callbacks and OpenAPI output. ScopeFor and RoleFor bind requirements to one scheme. Optional scope blocks on OAuth flow constructors replace scheme defaults, including explicitly empty inventories. Authentication and granted permissions remain application-owned.
Two atomic commits address #983 and #982. Regenerate endpoints and OpenAPI after upgrading. Required non-OAuth names now emit as role arrays in OpenAPI 3.1/3.2; 3.0 imports continue rejecting nonempty role arrays.
Validation: affected package and security regression tests, generated callback and imported HTTP execution tests, HTTP/gRPC/JSON-RPC projections, race checks, libopenapi and pinned Vacuum validation, independent-process byte determinism, and bounded base/current generation comparisons with compiled output. Existing default-only designs retain identical generated output. Independent reviews completed for each commit; mandatory commit and push hooks run for delivery. Public docs, consumer guidance and the import coverage ledger are updated.
Security requirements can now specify OAuth scopes or application roles for individual authentication schemes, alongside shared requirements.
OAuth flows can define independent scope inventories; flows without their own inventory inherit scheme defaults, while an explicitly empty inventory remains empty.
OpenAPI import and export preserve flow-specific scope names and descriptions, as well as per-scheme security requirements.
Improvements
Invalid scheme references and unsupported OAuth scopes are validated during import and rendering. Non-OAuth role requirements are supported in OpenAPI 3.1 and 3.2; OpenAPI 3.0 requires these lists to be empty.
Authorization callbacks receive the required names for each scheme to validate.
The change adds per-scheme OAuth scope and non-OAuth role requirements, plus independent OAuth flow scope inventories. It updates the expression model, DSL, code generation, OpenAPI import and export, and related tests and documentation.
Changes: Security requirement and scope model
Layer / File(s)
Summary
Security model and DSL expr/security.go, security/scheme.go, dsl/security*.go, docs/authorization.md, docs/dsl-reference.md
Security requirements can bind scope or role names to a selected scheme. OAuth flows can declare their own scope inventories; an omitted inventory inherits scheme defaults, while an empty inventory remains empty.
Requirement copying and equality include per-scheme requirements. Validation and scope-name projection use effective flow inventories, and copied scope declarations do not share the original slices.
Security code generation
Layer / File(s)
Summary
Runtime data and OpenAPI generation codegen/service/*, codegen/generator/testdata/*, http/codegen/openapi/..., http/codegen/*security*test.go, grpc/codegen/security_scope_test.go, jsonrpc/codegen/security_scope_test.go
Generated service data resolves flow scopes and preserves explicit empty inventories. OpenAPI output assigns scope maps to individual flows and emits required names for the relevant schemes.
OpenAPI security import and rendering
Layer / File(s)
Summary
Import model and requirement validation internal/openapiimport/model.go, internal/openapiimport/security.go, internal/openapiimport/security_credentials.go, docs/openapi-import-coverage.md
Imported OAuth scope names and descriptions are stored per flow. Security requirements retain separate per-scheme arrays and are validated for known schemes, duplicate entries, defined OAuth scopes, and OpenAPI-version rules for non-OAuth arrays.
Import and regeneration coverage internal/openapiimport/*test.go, internal/openapiimport/testdata/security_credentials/*, internal/openapiimport/tla/security_credentials/README.md
Tests cover independent flow scopes, per-scheme requirements, version boundaries, unknown scopes, and generated credential validation.

Explanation
The PR implements the coding requirements for [#983] and [#982]. SecurityExpr.SchemeRequirements, ScopeFor, and RoleFor preserve per-scheme OAuth scopes and non-OAuth role names while retaining security alternatives. FlowExpr.Scopes, FlowScopes, and the importer preserve independent flow inventories, descriptions, inheritance, and explicit empty inventories. OpenAPI generation emits per-flow scopes and per-scheme requirement arrays. Import rendering validates undefined OAuth scopes and applies the OpenAPI 3.0 role-array boundary. Focused DSL, expression, importer, generated callback, HTTP, gRPC, JSON-RPC, and OpenAPI tests cover the stated boundaries and projections. The coverage ledger and validation documentation are updated.

Explanation
The reviewed changes stay within [#983] and [#982]. Source changes implement security ownership, flow inventories, import, generation, and validation. Tests, regenerated fixtures, coverage documentation, consumer documentation, and TLA+ models verify or document those behaviors. No unrelated product behavior is established by the reviewed change summary or focused source inspection.

A rabbit reads each flow with care, And keeps its scope map tucked in there. One scheme gets roles, one scopes its own, No empty list is overthrown. The bunny hops through tests at night, And leaves each generated map just right.

Update the SecurityRequirementScheme.Scopes contract.
The field comment says API-key arrays must be empty. The new validator accepts nonempty non-OAuth role arrays in OpenAPI 3.1 and 3.2. Update the comment so callers of the normalized model do not reject supported requirements. (raw.githubusercontent.com)
As per coding guidelines, “Every exported type, function, method, and field must have a GoDoc comment explaining its contract.”
Proposed comment update
- // Scopes contains the authored scopes. Supported API-key schemes require- // this list to be empty.+ // Scopes contains OAuth scope names or non-OAuth role names.+ // Non-OAuth arrays must be empty in OpenAPI 3.0.

Addressed the outside-diff finding on SecurityRequirementScheme.Scopes in commit 5f88142 (PR #1055). The GoDoc now describes OAuth scopes and non-OAuth application roles in OpenAPI 3.1/3.2, while retaining the 3.0 empty-list requirement. Focused expression/importer security tests, lint, and the full pre-push root suite passed. All three inline findings were also fixed and their threads resolved.
