a961e241cd feat(audit): complete drift detection shard implementation (Yellow → Green) 
- Implement 4 production-ready audit scan tools in src/shards/audit.py
  - scan_status_reconciliation: detect terminated users still enabled in AD
  - scan_job_title_drift: detect title mismatches between Workday and AD
  - scan_department_mismatches: detect department/cost center drift
  - scan_name_variance_mismatches: detect display name inconsistencies
- Add comprehensive integration test suite (tests/integration_test_audit_shard.py)
- Create demo client (test_client.py) and MCP protocol simulator (test_mcp_protocol.py)
- Add tool catalog generator (list_tools.py) for visibility across all 33 registered tools
- Fix Windows console encoding in src/main.py to support emoji in shard status output
- Add version management utility (scripts/bump_version.py) for release automation
- Update workday test imports to use new drift_detection module path

Completes session goal of establishing SOC 2-compliant cross-system drift detection
per SESSION_SNAPSHOT_2026-04-13.md. All audit tools validated against mock data
with expected mismatch scenarios (Bob Martinez, Carol Chen, David Kim cases).

6337182226 feat: Add enterprise system resilience and graceful degradation 
Resolves CRITICAL #1 from code-health-report-2026-04-13.md

Changes:
- Add tenacity dependency for retry logic
- Create lib/resilience.py with:
  - resilient_http_call decorator (3 retries, exponential backoff 2s→4s→8s)
  - CircuitBreaker class (opens after 5 consecutive failures)
  - handle_404_gracefully decorator for safe resource lookups
- Apply retry decorators to all HTTP clients:
  - workday_client.py: get(), raas()
  - entra_client.py: get(), get_all_pages()
  - helix_client.py: get(), post()
  - intune_client.py: get()
  - lansweeper_client.py: gql()
  - fedex_client.py: post()
- Add graceful degradation to audit tools:
  - audit_user_drift(): Wrap Workday, AD, Entra calls separately
  - audit_device_drift(): Wrap Lansweeper, Intune, Helix calls separately
  - Both now return systems_available and systems_failed fields
- Create check_system_health() tool for proactive monitoring
- Add comprehensive unit tests for resilience module

Benefits:
- HTTP clients now automatically retry transient failures (5xx, timeouts)
- Circuit breaker prevents hammering failing services (fast-fail after threshold)
- Audit tools continue with partial data if some systems unavailable
- Health check tool enables proactive system monitoring before bulk audits

bb1a2e3954 feat(copilot): add FrankGPT instruction framework 
- Add [FrankGPT consolidated instructions](.github/agents/FrankGPT.consolidated-instructions.md) and supporting standards in [.github/instructions/core.instructions.md](.github/instructions/core.instructions.md) to define agent modes, commands, and workflows.
- Expand prompt and knowledge assets, including [.github/prompts/create-commit.msg.prompt.md](.github/prompts/create-commit.msg.prompt.md), to standardize ITIL-aligned reasoning and improve session-aware commit/message generation.
