chore: add PROJECT_STATE.md to all active projects and clients

Establishes inter-session coordination for 29 projects/clients:
- Full lock/component format for active projects (dataforth-dos,
  radio-show, cascades-tucson, valleywide, instrumental-music-center,
  lens-auto-brokerage, msp-audit-scripts)
- Light format for complete/stalled/planning (msp-pricing, pavon,
  wrightstown-*, gururmm-agent, community-forum, glaztech, etc.)
- Onboarding stubs for recently added clients

+## Active Session Locks
+
+| Session | Working On | Status | Started |
+|---------|-----------|--------|---------|
+| _(none active)_ | | | |
+
+**How to claim a lock:** Add a row before starting work. Remove it when done. Locks older than 2 hours with no update are considered stale.
+
+---
+
+## Current State
+
+**Status:** ACTIVE / DEPLOYED
+**Last Activity:** 2026-04-14
+
+Legacy DOS hardware test pipeline for Dataforth Corporation. Node.js service (`testdatadb`) on AD2 (192.168.0.6) parses test log files from DOS-era test stations, stores 27k+ records in SQLite, and publishes datasheets to the web. As of 2026-04-12, pipeline was extended to support SCMVAS/SCMHVAS product families with a new VASLOG parser and accuracy-only datasheet template. 27,503 historical records backfilled; 434 Engineering-Tested .txt files imported. Service is production-deployed and running.
+
+Remaining work: deploy session manager to SAGE-SQL, verify historical backfill accuracy for edge cases, continue any new product family extensions.

+
+## Infrastructure / Access
+
+| Component | IP/Location | Notes |
+|-----------|-------------|-------|
+| AD2 (primary) | 192.168.0.6 | Windows Server 2022, hosts testdatadb service on port 3000 |
+| AD1 | 192.168.0.27 | Hosts Engineering share at \\AD1\Engineering |
+| D2TESTNAS | 192.168.0.9 | SMB1 only — bridge for DOS test stations |
+| VPN required | FortiClient | Must be connected to reach 192.168.0.x |
+
+**Service:** `testdatadb` on AD2, account `INTRANET\svc_testdatadb`, working dir `C:\Shares\testdatadb`, API port 3000.
+**Database:** SQLite at `C:\Shares\testdatadb\database/testdata.db` (4.1 GB, not in git).
+**Web output:** `\\ad2\webshare\For_Web` (NOT `X:\For_Web` in SSH sessions).
+
+**Credentials:**
+```bash
+# AD2 password (strip backslash escape)
+bash D:/vault/scripts/vault.sh get-field clients/dataforth/ad2.sops.yaml credentials.password | sed 's/\\//g'
+# AD1 password
+bash D:/vault/scripts/vault.sh get-field clients/dataforth/ad1.sops.yaml credentials.password
+```
+
+**Anti-patterns:** See `CONTEXT.md` — especially: no X: drive in SSH, no 50+ args on PowerShell, no hardcoded passwords, no SMB1 on AD2.

+
+## Pending / Next Up
+
+- [ ] Deploy session manager to SAGE-SQL
+- [ ] SCMVAS/SCMHVAS pipeline further extension (if new families identified)
+- [ ] Verify 27,503 historical records backfill accuracy (438 plain-decimal edge cases patched 2026-04-12)
+- [ ] Clean vault entry: ad2.sops.yaml has stale backslash in password (remove `\` escape)

+
+## How to Update
+
+**When starting:** Add your session to Active Session Locks (Session = "User/Machine", e.g. "Mike/DESKTOP-0O8A1RL").
+**When finishing:** Remove your lock row, add entries to Recent Changes, update Current State if needed.
