 - Closing the desktop dashboard does NOT stop the supervisor or worker.
 - The dashboard automatically reconnects/reloads when the worker goes down and returns during an update.
 - Existing browser access at http://127.0.0.1:8788 remains available.
+
+Supervisor detection hotfix 1.9.1:
+- Desktop dashboard no longer relies on os.kill(pid, 0) to detect the SYSTEM-owned supervisor.
+- Uses Windows OpenProcess(PROCESS_QUERY_LIMITED_INFORMATION) when available.
+- Uses localhost dashboard health and recent supervisor_state.json as additional valid signals.
+- Prevents false 'ERP Local Agent supervisor did not start' errors caused by cross-user Windows process permissions.
+
+Single-supervisor hotfix 1.9.2:
+- Replaces PID-text singleton logic with an msvcrt held byte-range file lock that works across Windows processes/logon sessions.
+- Duplicate supervisors immediately exit without starting/killing workers.
+- Desktop dashboard never launches an interactive supervisor when the installed ERP Local Agent Scheduled Task exists.
+- If the task exists but is stopped, dashboard requests Task Scheduler to start it and waits for localhost health.
+- Prevents supervisor/worker restart storms caused by multiple supervisors killing one another's workers.
+
+Global mutex hardening 1.9.3:
+- Supervisor primary singleton is Windows Global\ARRR_ERP_Local_Agent_Supervisor via CreateMutexW.
+- Existing byte-range lock remains only as fallback if Global mutex creation is unavailable.
+- Scheduled Task installation is expected to use MultipleInstances=IgnoreNew.
+
+
+Tally GSTIN enrichment 1.9.4:
+- Loaded-company discovery requests GSTRegistrationNumber, GSTRegistrationDetails, GSTIN and PartyGSTIN.
+- Company parser searches GSTIN candidates recursively, including nested GST registration details.
+- Existing company GUID/name discovery remains unchanged.
