Changelog
All notable changes to the application and documentation are tracked here (consolidated).
Application Releases
3.2.3 (2025-10-17) — Dashboard Hardening
- Issue #56 — Hardened home dashboard for selective runtime modes (
--ux,--saf-orchestrator). - routes.py: logging on index, safe defaults, graceful fallback.
- features/dashboard/lib/dashboard_service.py: completed fallback keys, info/debug logs.
- Result: no 500 on
/across modes; clearer diagnostics.
3.2.2 (2025-10-17) — CLI Runtime Modes (Phase 1)
- Issue #47 — Single entrypoint
main.pywith normalized flags. - Only-mode:
--ux,--monitoring [DATASOURCE],--rule-engine; disable in default:--no-monitoring,--no-rule-engine. --port,--db-instance;--helplists valid monitoring datasources.
3.2.1 (2025-10-13) — Monitoring UX + Offset & SSL Stabilization
- AVEVA client 401 refresh + diagnostics; monitoring scan_error enrichment.
- Restart endpoints respect
offset_seconds; monitoring UI spacing improvements.
2025-10-17
- Issue #50 — follow-up: Trial request no longer requires SSO to submit.
- Anti-abuse added to Trial form: honeypot (
hp_contact) and IP rate‑limiting (3 requests / 5 minutes). - Trial page copy updated to advise using Google/Microsoft email for later SSO.
- Admin review remains read‑only at
GET /admin/trials; one JSON per request saved underinstance/public/trial_requests/. - See details: docs/notes/issue-50.md

Version 3.2.3 (October 17, 2025) - Dashboard Hardening
ԣ� COMPLETED: Issue #56 ��� Dashboard Hardening for Selective Runtime Modes
Hardened the main Dashboard (home) to render reliably under selective runtime modes (--ux, --saf-orchestrator) without 500s, adding safe defaults and targeted logging.
Changes
routes.py: Added logging on index route, verified registered blueprints, and ensured safe defaults to avoid template key errors. Graceful fallback rendering on exceptions.features/dashboard/lib/dashboard_service.py: Completed fallback dict (added missing keys), added info/debug logs, returned consistent structure even on errors.- Lazy imports in Orchestrator routes to avoid circular imports/side effects during app startup.
Outcome
- No 500 on
/across modes; dashboard renders with meaningful zeros/defaults when data sources are unavailable. - Clear logs for diagnostics in selective runtime scenarios.
Version 3.2.2 (October 17, 2025) - CLI Runtime Modes (Phase 1)
ԣ� COMPLETED: Issue #47 ��� CLI runtime modes for selective component startup
Introduce runtime modes via single entrypoint (main.py) to start selected components and enable workload partitioning.
Features
- Single entrypoint retained (
main.py), backwards-compatible: no flags ��� Web + Monitoring + Rule Engine. - Only-mode (union semantics):
--ux,--monitoring [DATASOURCE],--rule-engine. - Disable flags (default mode only):
--no-monitoring,--no-rule-engine. - Server option:
--port <int>(default 5000). - DB override:
--db-instance <name|URI>(alias:--db-istance). - Help enhanced:
--helplists allowed monitoring datasources. - Logging: resolved run-set, datasource selection, and Phase 1 warnings.
Monitoring Datasources (allowed values)
connect-data-source,azure-iot-hub,opc-ua-server,mqtt-broker,modbus-tcp,rest-api
Phase 1 Constraints
- Datasource is validated against a fixed allowlist; stream-level sharding not applied yet.
- Requires exactly one active
APIConfigurationwhen aDATASOURCEis provided.
Validation (smoke tests)
- Help output includes allowed datasources: ԣ�
- Parser only-mode union logic: ԣ� (
--ux --monitoring --rule-engine��� union) - Misuse detection: ԣ� (
--ux --no-monitoringfails fast with clear error) - Monitoring-only manual run observed to start APScheduler and remain active (user log): ԣ�
Documentation
- Added
docs/CLI_RUNTIME_MODES.mdwith flags, precedence, examples, and notes.
Version 3.2.1 (October 13, 2025) - Monitoring UX + Offset & SSL Stabilization
ԣ� COMPLETED: Review passed for Issue #45 (Offset + SSL) and Monitoring UX
Fixes & Improvements
- AVEVA Client: 401 token refresh + single retry; request diagnostics (status/url/error)
- Monitoring Engine: scan_error events enriched with HTTP diagnostics
- Restart endpoints: rispettano offset_seconds salvato (prima fase �ǣburst��� eliminata)
- Monitoring UI: griglia pi+� compatta; colonne ravvicinate senza ridurre il font; Actions visibile con �ǣShow Disabled��� senza sticky
Commits
- 982c1df Fix: apply offset on restart endpoints and enrich diagnostics
- a1d13ec UI: tighten Monitoring grid spacing, keep Actions visible (no sticky)

Version 3.2 (October 3, 2025) - Virtual Streams Phase 2
ԣ� COMPLETED: Virtual Streams Rule Engine Integration
Major Achievement: Virtual Streams fully integrated as first-class data sources for Rule Engine with simplified cross-rule reusability.
Key Features Delivered
- Simplified Naming Convention:
{variable_name}only (enables cross-rule reusability) - Rule Engine Integration: Full support for Virtual Streams as data sources
- UI Integration: Virtual Streams visible in Instance Mapping with
[VS]marker - Cross-Rule Reusability: Same variable name = same Virtual Stream across different rules
- Logging Component: Dedicated "Virtual Streams" component in System Console Log
- Bug Fix: Monitoring service errors resolved for non-numeric streams
Technical Implementation
VirtualStreamsService: Simplified naming convention with automatic create/updateRuleEngine: Helper method_get_stream_by_name()with VirtualStreamProxy duck-typingPlaceholderResolver: Virtual Streams fallback in placeholder resolutionAssetsService: Extendedget_active_streams()to include Virtual Streamsroutes.py: Legacy endpoint compatibility maintained
