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).

RACEMES - Changelog

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: --help lists 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 APIConfiguration when a DATASOURCE is 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-monitoring fails fast with clear error)
  • Monitoring-only manual run observed to start APScheduler and remain active (user log): ԣ�

Documentation

  • Added docs/CLI_RUNTIME_MODES.md with 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)

Validation

ԣ� Offset distribution stabile su restart singolo e bulk ԣ� Nessuna saturazione pool/SSL nei test locali ԣ� Migliore usabilit+� griglia Monitoring con Show Disabled


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/update
  • RuleEngine: Helper method _get_stream_by_name() with VirtualStreamProxy duck-typing
  • PlaceholderResolver: Virtual Streams fallback in placeholder resolution
  • AssetsService: Extended get_active_streams() to include Virtual Streams
  • routes.py: Legacy endpoint compatibility maintained
