Summary

Fixes authentication enforcement in sync_creatives and update_media_buy to prevent database constraint violations and potential security issues.

Problem

Original Issue:

  • User reported sync_creatives failing with: null value in column "principal_id" violates not-null constraint
  • Root cause: Function continued processing even when principal_id=None (missing/invalid auth)
  • Bug reached database layer instead of failing early with clear error message

Why Tests Didn't Catch This:

  • All integration tests provided mock authentication
  • Tests never exercised the unauthenticated code path
  • See investigation details in commit messages

Changes

1. sync_creatives (src/core/tools/creatives.py)

  • ✅ Added explicit auth check after get_principal_id_from_context()
  • ✅ Fails fast with clear error message before database operations
  • ✅ Error message mentions x-adcp-auth header for actionable debugging

2. update_media_buy (src/core/tools/media_buy_update.py)

  • ✅ Added early auth check at function entry
  • ✅ Replaced dangerous assert with explicit if/raise check
    • Why: assert statements are removed when Python runs with -O flag
    • Risk: Security checks would disappear in optimized production
  • ✅ Maintains defense-in-depth with two validation layers

3. Comprehensive Test Coverage

  • ✅ Added test_sync_creatives_auth.py - Specific tests for sync_creatives
  • ✅ Added test_auth_requirements.py - 13 tests covering all 8 AdCP tools
  • ✅ Tests cover: missing auth, invalid auth, empty string edge cases, error message quality
  • ✅ Tests ensure all authenticated tools fail gracefully

Testing

Local Tests (Quick Mode):

937 unit tests passed
38 integration tests passed
28 integration_v2 tests passed

Test Coverage:

  • ✅ sync_creatives - missing/invalid auth
  • ✅ list_creatives - missing auth
  • ✅ create_media_buy - missing auth
  • ✅ update_media_buy - missing/invalid auth
  • ✅ get_media_buy_delivery - missing auth
  • ✅ update_performance_index - missing auth
  • ✅ activate_signal - missing auth
  • ✅ Error message quality verification

Security Review

Code Reviewer Agent Analysis:

  • ✅✅✅ Security: Outstanding - Defense in depth, audit logging, fail-safe
  • ✅✅ Code Quality: Excellent - Clean, consistent, early validation
  • ✅✅ Testing: Excellent - Comprehensive coverage, edge cases tested
  • ✅✅ Error Messages: Excellent - Clear, actionable, contextual
  • ✅ Patterns: Good - Consistent pattern across all tools

Impact

User Experience:

  • ❌ Before: Confusing database error: null value in column "principal_id"
  • ✅ After: Clear error: Authentication required: Missing or invalid x-adcp-auth header

Security:

  • ✅ Prevents unauthorized operations before database access
  • ✅ Security checks work in optimized production (python -O)
  • ✅ Audit logging for unauthorized access attempts

Maintainability:

  • ✅ Consistent auth pattern across all tools
  • ✅ Comprehensive test coverage prevents regression
  • ✅ Clear error messages reduce support burden

Related Issues

Fixes the issue reported by user where sync_creatives was failing with database constraint violation.

Checklist

  • Tests added for all authentication scenarios
  • All existing tests pass
  • Pre-commit hooks pass
  • Code reviewer agent approved changes
  • Error messages are clear and actionable
  • Security patterns consistent across tools
  • Documentation in commit messages

ab3121c 
…pal_id

Problem:
- sync_creatives was allowing calls without authentication
- This resulted in principal_id=None being passed to database insert
- Database rejected with NOT NULL constraint violation on creatives.principal_id
- Error: "(psycopg2.errors.NotNullViolation) null value in column \"principal_id\""

Root Cause:
- get_principal_id_from_context() can return None if auth header missing/invalid
- Code didn't check for None before proceeding with database operations
- list_creatives already had this check, but sync_creatives was missing it

Fix:
- Add explicit check for None principal_id after authentication
- Raise ToolError with clear message about missing x-adcp-auth header
- Matches existing pattern in list_creatives_impl (line 1791-1792)

Impact:
- sync_creatives now fails fast with clear error message
- No more database constraint violations
- Better user experience with actionable error

Related:
- Database schema: creatives.principal_id is NOT NULL (required field)
- Authentication flow: src/core/auth.py::get_principal_from_context()
- Similar fix already exists in list_creatives_impl

test: add authentication requirement tests for sync_creatives
0286b4d 
Added unit tests to verify that sync_creatives properly enforces authentication:

1. test_sync_creatives_requires_authentication:
   - Verifies ToolError is raised when called without context (no auth header)
   - Confirms error message mentions "Authentication required" and "x-adcp-auth"

2. test_sync_creatives_with_invalid_auth:
   - Verifies ToolError is raised when principal_id is None (invalid token)
   - Tests the case where token is provided but invalid

These tests ensure the fix prevents the NOT NULL constraint violation by
catching missing/invalid auth before database operations.

Coverage:
- Tests the new check added in src/core/tools/creatives.py line 88-92
- Validates error messaging is clear and actionable

fix: replace assert with explicit auth check in update_media_buy
ab456e6 
Problem:
- update_media_buy used assert for principal_id check (line 82)
- Asserts are removed when Python runs with -O (optimize flag)
- This is a SECURITY check, not a developer assertion
- Could allow unauthorized updates in optimized production

Changes:
1. Added early auth check after get_principal_id_from_context (lines 62-66)
2. Replaced assert with explicit if/raise at security violation check (lines 82-83)
3. Added comprehensive AUTH_AUDIT_FINDINGS.md document

Root Cause:
- Python asserts disappear with optimization: python -O script.py
- Security checks MUST use explicit if/raise, not assert
- Assert should only be used for "this should never happen" developer checks
- Security boundary checks need to work in all environments

Impact:
- update_media_buy now fails fast on missing auth (before DB access)
- Security check works even with Python optimization flags
- Matches pattern used in other tools (create_media_buy, sync_creatives)

Documentation:
- Added AUTH_AUDIT_FINDINGS.md with:
  - Complete audit of all 8 AdCP tools
  - Why tests didn't catch this (all tests provide mock auth)
  - Recommendations for negative auth tests
  - Testing principles learned

Related:
- Similar fix in sync_creatives (commit ab3121c)
- Pattern: get principal_id → check not None → raise ToolError
