Schema alignment tests were silently skipping in CI because the schemas/ directory is gitignored. Replace file-path-based schema loading with on-demand HTTP download from adcontextprotocol.org with local caching. Also remove stale --ignore flags in CI workflow and test runner that pointed to files already moved to tests/integration_v2/. Surfaced pre-existing spec drift (tracked separately): - GetSignalsRequest missing signal_ids and pagination fields - GetProductsRequest missing brand, catalog, buyer_campaign_ref fields
…sRequest GetProductsRequest: add brand, catalog, buyer_campaign_ref (spec fields not yet in adcp library v3.2.0). Prevents extra_forbidden rejections for spec-compliant requests. GetSignalsRequest: add signal_ids and pagination (same pattern). Update test_adcp_contract.py drift assertions with explicit allowlists for locally-extended spec fields. All 2003 unit tests pass, 25/25 schema alignment tests pass.
Some e2e tests read os.environ directly for port lookup (e.g., test_a2a_endpoints_working.py, test_landing_pages.py). Previously these vars were only set in the subprocess env dict, not in the test process itself.
Replace gutted test_adcp_full_lifecycle.py with a real 4-phase lifecycle test (get_products -> create_media_buy -> sync_creatives -> delivery). Delete 4 dead files: placeholder tests and obsolete strategy simulation.
Add three new unit test suites for migration safety net: - test_auth_consistency: verifies auth middleware behavior across all MCP tools (missing token, invalid token, anonymous discovery access) - test_error_format_consistency: verifies error shapes across MCP and A2A transports, including cross-transport consistency - test_response_shapes: verifies serialized response structure for all major AdCP operations via model_dump(mode="json") Also applies ruff formatting fixes to touched files.
…t_creatives Complete the coverage matrix for the two core tools that were missing shape and error path tests: - UpdateMediaBuySuccess: field types, affected_packages nesting, internal field exclusion - ListCreativesResponse: creative fields, query_summary, pagination, format_id structure - Error paths: missing context/auth for both MCP and A2A transports
6-atom workflow per UC: read-scenarios (trace contextgit) → cross-reference (classify coverage) → review → triage → implement → commit. Each atom runs in fresh context to prevent drift across 130+ scenarios. Formula cooked into 55 atoms under epic salesagent-72th.
…req scenarios Maps BDD scenarios from adcp-req (BR-UC-001 through BR-UC-009) into behavioral snapshot tests that lock current salesagent behavior before FastAPI migration. Each test file covers one use case: - UC-001: get_products (32 tests) - ranking, access control, pricing - UC-002: create_media_buy (18 tests) - validation, creative pipeline - UC-003: update_media_buy (13 tests) - flight dates, budget, packages - UC-004: delivery (21 tests) - orchestration, circuit breaker, filters - UC-005: creative_formats (17 tests) - sort order, filters, boundaries - UC-006: sync_creatives (16 tests) - status transitions, Slack guards - UC-007: authorized_properties (31 tests) - policy assembly, context echo - UC-009: performance_index (9 tests) - mapping, batch, A2A validation UC-008 (signals) excluded - dead code path.
…iveStatus enum Two changes: 1. Add ruff TID251 banned-api rule for inspect.getsource() — structural tests that grep source code provide zero regression protection. 6 existing violations flagged (to be replaced with behavioral tests). 2. Fix build_creative default status from 'active' (invalid) to 'processing' (valid CreativeStatus enum value). This broke test_four_phase_lifecycle e2e test.
Replaced all tautological structural tests (grep-as-test anti-pattern) with real behavioral tests that exercise actual code paths: - test_create_media_buy_behavioral: 2 tests now call _create_media_buy_impl to verify CREATIVE_UPLOAD_FAILED and CREATIVES_NOT_FOUND error codes - test_dry_run_no_persistence: removed redundant structural test (covered by existing test_dry_run_returns_simulated_response) - test_gam_placement_targeting: 2 tests call _update_media_buy_impl to verify invalid_placement_ids and placement_targeting_not_supported errors - test_incremental_sync_stale_marking: 2 tests call _run_sync_thread to verify incremental sync skips stale marking while full sync calls it - test_inventory_adapter_restrictions: test calls MockAdServer directly to verify no-targeting requests are accepted without validation errors inspect.getsource() is now banned via ruff TID251 (previous commit).
…a2a tests
3 unit tests were silently skipping due to importing core_get_signals_tool
which was removed (signals is dead code). The overly broad except clause
`if "a2a" in str(e)` matched the module path in the error message,
producing a misleading "a2a library not available" skip.
Changes:
- Remove all core_get_signals_tool references from test imports/assertions
- Fix test_async_functions: list_creatives and sync_creatives are sync, not
async — this was a hidden bug masked by the bogus skip
- Tighten ImportError handling in 8 test files (3 unit + 5 e2e): use
`e.name.startswith("a2a")` to only catch actual a2a-sdk library absence,
not any ImportError from modules whose path contains "a2a"
Result: 3 previously-skipped tests now pass (10/10 in file, 0 skipped)
…e tests Signals is dead code (UC-008) — removed from both MCP and A2A transports. But 4 test files still referenced GetSignalsRequest/get_signals in their test matrices, producing 2 misleading skips and stale test coverage. Changes: - test_pydantic_schema_alignment.py: remove GetSignalsRequest from SCHEMA_TO_MODEL_MAP (eliminates 2 skipped tests) - test_mcp_tool_type_alignment.py: remove get_signals from tool-schema pair list - a2a_response_validator.py: remove get_signals from expected skill fields and handler methods Result: 2244 passed, 0 skipped (was 2243 passed, 5 skipped)
…rsions Replace all hardcoded GAM API version strings (v202411, v202505) with the GAM_API_VERSION constant from constants.py. The v202411 version has been deprecated and disabled by Google, causing API calls to fail with ApiVersionError.UPDATE_TO_NEWER_VERSION.
- Add 11 GAM e2e tests verifying real API connectivity: connection, inventory discovery, advertiser listing, adapter init, health checks - Fix GAMHealthChecker to support service_account_json (was key_file only) - Fix GAMHealthChecker to pass network_code from client manager - Fix SOAP object attribute access in health checker (use [] not .get()) - Add GAM fixtures to e2e conftest with credential auto-discovery - Gate tests behind @pytest.mark.requires_gam marker Test network: 23341594478 (salesagent-e2e service account)
Only use environment variables (GAM_SERVICE_ACCOUNT_JSON, GAM_SERVICE_ACCOUNT_KEY_FILE) for GAM test credentials.
Converts the manual GAM automation test script into proper pytest e2e tests that create real GAM orders via the adapter, verify line item types, and test archive lifecycle operations. 5 tests covering: non-guaranteed CPM orders (PRICE_PRIORITY), guaranteed CPM orders (STANDARD), advertiser verification, order archival, and guaranteed activation workflow.
Expand test coverage to include order lifecycle management: - test_pause_media_buy: pause via adapter's update_media_buy - test_pause_then_archive_order: create → pause → archive flow (mirrors manual script's test_lifecycle_archive_order) - Add Principal seed data for MediaBuy FK constraint - Add _persist_media_buy helper for lifecycle tests that need DB records (update_media_buy requires MediaBuy/MediaPackage) All 6 tests verified against real GAM API.
GAM SDK returns zeep CompoundValue objects, not Python dicts.
These support obj["key"] and "key" in obj, but NOT obj.get().
Fixed in orders.py:
- get_order_status: result.get("results") → "results" in result
- archive_order: result.get("numChanges", 0) → bracket access
- get_order_line_items: removed isinstance(result, dict) guard
- check_order_has_guaranteed_items: same pattern
- update_line_item_budget: same pattern
- _update_line_item_status: same pattern
- approve_order: getattr → bracket access for consistency
Fixed in creatives.py:
- line_item.get("creativeRotationType") → bracket access

Replace asyncio.new_event_loop() + run_until_complete() calls with run_async_in_sync_context() from validation_helpers, which correctly handles both sync and async caller contexts via a thread pool. This eliminates the deadlock risk when get_format() or list_available_formats() are called from an async context (e.g., FastMCP tools). Also applies the same fix to list_available_formats(), removing its hand-rolled dual-path asyncio detection logic in favor of the shared helper.
All /debug/* route handlers are now grouped under a dedicated sub-router with a FastAPI dependency that returns 404 when ADCP_TESTING is not set, preventing internal state exposure in production.

- Add regression tests for all 3 hardening items
…ty internals Move set_current_tenant() calls out of resolver internals (_detect_tenant, get_principal_from_token, resolve_identity) and into transport boundaries (REST auth deps, A2A handler, MCP wrapper). get_principal_from_token() now returns (principal_id, tenant_dict) tuple instead of mutating global state. Also fixes pre-existing mypy errors in auth_context.py (MappingProxyType vs dict type mismatch).
…actored auth - xfail schema alignment tests that validate against /schemas/latest/ (a moving target ahead of the adcp library we depend on — no versioned URLs exist) - Replace hardcoded 2026-03-01 dates with relative future dates to prevent "start time in the past" validation failures - Update tenant isolation test to match post-4csg architecture where get_principal_from_context returns tenant context instead of setting ContextVar

- Expand _get_covered_obligations() to scan unit entity tests (test_media_buy.py, test_creative.py, test_delivery.py) in addition to integration tests (test_*_v3.py) - Add 282 Covers: tags mapping unit tests to obligation IDs across all 3 entity test files (89 media-buy, 134 creative, 59 delivery) - Delete 10 empty xfail stubs and 3 empty test classes from test_media_buy.py (all had pytest.fail() bodies with no logic) - Shrink obligation_coverage_allowlist.json from 733 to 593 entries (140 obligations now covered by unit tests) - Add scripts/add_covers_tags.py for reproducible tag insertion
The test_model_accepts_minimal_request test generates requests from the live AdCP schema, which may include fields not yet in the adcp library (e.g., account on SyncCreativesRequest). Strip these known mismatch fields before instantiation to avoid extra_forbidden errors.

Brilliant idea — this is exactly the kind of self-healing behavior buyer agents need. Already tracked in #1072 (depends on this PR's |
…ly in A2A handler
resolve_identity() wraps tenant dicts in TenantContext (Pydantic model), but downstream isinstance(tenant, dict) checks failed silently for TenantContext, causing redundant DB queries on every request. Fix: set_current_tenant() now normalizes TenantContext and LazyTenantContext to plain dict before storing in the ContextVar. This is the single conversion point - callers pass whatever they have and the ContextVar always holds dict[str, Any]. Also removes isinstance(identity.tenant, dict) guards in context_helpers.py that are no longer needed since the normalization happens at the storage boundary.
…n product loader The conversion layer rejected auction CPC with a stale restriction from adcp 2.5.0 (commit d8c9019). The adcp library (now 3.2.0) explicitly supports auction CPC via CpcPricingOption with floor_price/price_guidance fields. Removes try/except ValueError/continue in both product loaders (products.py and main.py) that silently dropped unconvertible products — violating the "No Quiet Failures" principle.

Repository Pattern & Multi-Tenant Hardening
MediaBuyRepository + Unit of Work
MediaBuyRepositoryencapsulates allMediaBuyandMediaPackagedata access behind tenant-scoped methods. Every query includestenant_idin the WHERE clause automatically — callers cannot bypass isolation.MediaBuyUoWwraps session lifecycle (begin/commit/rollback) and exposes the repository._implfunctions receive the UoW via dependency injection instead of callingget_db_session()inline.Write methods (
create_from_request,update_status,update_fields,create_package,create_packages_bulk) add objects to the session but never commit — the UoW handles commit/rollback at the boundary.create_from_request()accepts the Pydantic request model directly and serializesraw_requestinternally — this eliminated 4model_dump()calls from_create_media_buy_impl, keeping serialization at the repository boundary where it belongs.Cross-tenant query leaks fixed
