 # PROJECT_STATE - OTB Billing
 
+## v1.4.0 - 2026-05-18
+
+Current state:
+- OTB Billing is running on outsidethedb.
+- Service: otb_billing.service.
+- App port: 5050.
+- Project path: /home/def/otb_billing.
+- /health renders the standard health grid with:
+  - Status
+  - Database
+  - Uptime
+  - Load Average
+  - Memory
+  - Disk
+  - Operations Bal
+  - Treasury Bal
+  - Crypto Reconcile
+- Operations Bal and Treasury Bal show USDC, ETH, ETHO, EGAZ, and ETI balances.
+- Coin names in balance cards are clickable and open the relevant explorer address page:
+  - Arbiscan for Arbitrum USDC
+  - Etherscan for Ethereum ETH
+  - explorer.ethoprotocol.com for ETHO
+  - explorer.etica-stats.org for EGAZ/ETI
+- Crypto Reconcile card shows timer/service state plus payment queue stats.
+- Reconcile Now button on /health manually starts the existing crypto reconciliation worker.
+- Crypto reconcile worker remains timer-driven by otb-billing-crypto-reconcile.timer every 15 minutes.
+- otb-billing-crypto-reconcile.service is a one-shot service; inactive between timer runs is normal.
+- Current version: v1.4.0.

+# OTB Billing - v1.4.0
+
+Build date: 2026-05-18
+
+## v1.4.0 changes
+
+- Added clickable explorer links for payment asset names in the Operations Bal and Treasury Bal cards.
+- Added Crypto Reconcile health card to the main /health grid.
+- Crypto Reconcile card now shows:
+  - timer status
+  - service status
+  - pending crypto payments
+  - confirmed crypto payments today
+  - stale pending crypto payments
+- Added Reconcile Now button on /health to manually trigger the existing crypto reconciliation worker.
+- Fixed crypto payment queue stats to use the project DB helper instead of guessing DB config.
+- Kept the reconcile worker as a systemd timer-triggered one-shot service; inactive service state between runs is expected when the timer is active.
+- Bumped footer/app version from v1.3.0 to v1.4.0.
