feat(spp_api_v2): OpenAPI polymorphic bodies, OAuth2 scheme in auth middleware, bundle schemas (re-land from #76)

[gonzalesedwin1123]

Re-lands the spp_api_v2 portion of reverted PR #76 (revert: #271). Everything listed is contained in THIS PR's diff.

Summary

• utils/openapi_polymorphic.py: polymorphic_body() helper + OpenAPI schema-injection hook, installed on the app via the endpoint registry.
• Auth middleware: OAuth2 client-credentials security scheme replacing plain HTTPBearer (advertises the token endpoint in OpenAPI), Bearer-prefix stripping.
• BundleEntry.resource becomes a polymorphic Individual/Group body; schema import-order fix.
• New OpenAPI contract/polymorphic/bundle tests.

Added on top of #76 (not in the original)

• gemini-code-assist review findings, both applied: the polymorphic hook now delegates to the app's original openapi() generator and injects schemas into its output, preserving app metadata (contact, license_info, servers, tags) that feat: geofence-based geographic targeting for programs #76's direct get_openapi() call dropped; the Bearer-prefix strip also trims surrounding whitespace.
• Version bump + HISTORY entry; README rendered from the updated fragment.

Note: tests/test_search_service.py name-assertion updates from #76 landed with the revert itself (#271 kept them aligned with the retained spp_registry name fix), so they are not part of this diff.

Verification

• ./spp t spp_api_v2: 640 passed, 0 failed (includes OpenAPI contract tests)
• codecov: patch pass
• All gemini-code-assist threads resolved with fixing-commit references

Code Review

This pull request introduces polymorphic OpenAPI schema utilities to document BundleEntry.resource as a polymorphic Individual/Group body, replaces the plain HTTPBearer authentication scheme with an OAuth2 client-credentials scheme, and adds corresponding contract and unit tests. The review feedback highlights two main improvements: first, in openapi_polymorphic.py, the custom OpenAPI hook should call the original app.openapi method instead of calling get_openapi directly to avoid discarding app metadata; second, in auth.py, the token extraction should strip any leading or trailing whitespace after slicing the 'Bearer ' prefix to ensure robust JWT decoding.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.

gemini-code-assist disposition:

Applied: Bearer-prefix strip now also trims whitespace (token[7:].strip()). Suite: 640/0.

Deferred: openapi_polymorphic.py using the app's original openapi() instead of a partial get_openapi call — agreed in principle (contact/license metadata), but the OpenAPI contract tests pin the current output; changing generation belongs in its own PR with contract-test updates.

[gonzalesedwin1123]

Update: the deferred OpenAPI finding is now applied — the polymorphic hook delegates to the app's original openapi() generator and injects schemas into its output, preserving contact/license_info/servers/tags. Contract/polymorphic/bundle tests all pass (640/0). All gemini findings on this PR are now addressed.

Reviewed with a focus on downstream modules that extend the api_v2 app (via _get_fastapi_routers() or by importing the auth middleware / shared schemas). Overall this is safe to land — Depends(get_authenticated_client) consumers re-resolve against the new signature without code changes, the polymorphic hook only injects models that are actually $ref'd, and runtime types deliberately stay dict. Two things worth addressing, two worth knowing:

1. BundleEntry.resource docs are now wrong for spp_api_v2_products (should fix or track).
spp_api_v2_products/routers/product.py:131 builds BundleEntry(resource=data) where data is a Product dict, returned through the shared Bundle response model. The shared schema now documents resource as oneOf [Individual, Group], and test_bundle_openapi.py asserts the list is exactly those two on the grounds that bundle_service only supports them — but BundleEntry is reused by other routers with other resource types. The Product search response is now actively mis-documented, and strict validators / codegen against the spec will flag Product payloads as invalid. Runtime is unaffected. Suggestion: give reusing modules their own entry schema, or provide a way to extend the oneOf where Bundle is reused, rather than baking bundle_service's restriction into an app-wide schema.

2. Relative tokenUrl: "oauth/token" may resolve to the wrong URL (please verify manually).
The app mounts at /api/v2/spp (data/fastapi_endpoint.xml:6) and the real endpoint is POST /api/v2/spp/oauth/token (routers/oauth.py:95). Per OpenAPI 3, relative URLs resolve against the server URL, and RFC 3986 resolution of oauth/token against /api/v2/spp drops the last path segment → /api/v2/oauth/token (404). Some Swagger UI versions resolve against the spec URL instead, which happens to give the right answer — but since discoverability for consumers like QGIS is the point of this change, please verify the Authorize flow in Swagger UI and QGIS against a running instance, or derive the path from the endpoint's root_path. (Relative does adapt if an instance mounts under a different root path, so an absolute hardcode has its own downside.)

3. Auth is slightly more lenient now (informational).
A raw JWT without the Bearer prefix is now accepted (previously HTTPBearer rejected it with 401 "Missing Authorization header"), and a non-Bearer scheme like Basic xyz now fails as "invalid token" rather than "missing header". Not a security weakening, but clients can start silently depending on the no-prefix form. Also note: any code calling get_authenticated_client() directly with an HTTPAuthorizationCredentials object (rather than via Depends) would now break with an AttributeError — no such caller exists in this repo, but it's a real signature change for extenders.

4. Silent wrong-$ref on schema-name collision (hardening).
The hook injects by bare class name with components.setdefault(name, ...). If FastAPI already generated a different schema under that name (duplicate Pydantic model names across modules on the same app), the hand-built $ref silently points at the wrong model — and the contract test won't catch it, because the ref resolves. A _logger.warning when the name already exists with different content would make that diagnosable.

Nits:

• schemas/bundle.py imports the helper absolutely (from odoo.addons.spp_api_v2.utils...) while importing sibling schemas relatively; from ..utils.openapi_polymorphic import ... would match the file's style.
• The schemas/__init__.py reorder is harmless but not needed — bundle.py imports its own dependencies, so the comment implies a load-order constraint that doesn't exist.
• Test docstrings referencing "the plan's Open Questions section" and "Spike-confirmed shape" won't mean anything to a future reader; reword to describe the behavior itself.

Test coverage is good — the $ref-resolution contract test is exactly the guard downstream modules need. One gap: nothing asserts the OAuth2 scheme lands in securitySchemes or that tokenUrl resolves against the live oauth endpoint, which is where item 2 hides.
