[CLAUDE] Scripts Docs: Chunk T5+T6 — Final DELETE + verify NO re-seed loop (Plan T proven active)

Post-Plan T deploy Run #207 sha=0b97840 PASS — DemoSeed:Disabled flag
applied prod via appsettings.json (commit qua git, override
appsettings.Production.json gitignored).

T5 — Final DELETE sau flag deploy:
- scripts/plan-t5-final-cleanup.sql upload qua scp + sqlcmd -i
- 3 TRANSACTION DELETE: 4 PE + 1 V2 + 2 V1 = 7 rows direct + cascade child
- Post-state: PE=0 + V2=0 + V1=0 + Steps cascade=0 + Levels cascade=0

T6 — Verify NO re-seed loop (FORCE IIS recycle test):
- Restart-WebAppPool SolutionErp-Api → app pool Started
- Wait BE healthy (curl auth login 200)
- sqlcmd verify post-recycle DB state:
  * PE=0 ✅ NO re-seed
  * V2 workflows=0 ✅ NO re-seed
  * V1 workflows=0 ✅ NO re-seed
  * Users=33 ✅ preserved (SeedDemoUsers KEEP)
  * Suppliers=19 ✅ preserved (SeedDemoMasterData KEEP)
  * Projects=9 ✅ preserved (SeedDemoMasterData KEEP)
  * Contracts=7 ✅ preserved (bro chưa request xóa)

→ DemoSeed:Disabled flag PROVEN active end-to-end. DbInitializer skip 5
method seed, KHÔNG còn re-seed contaminate sau mỗi deploy.

Cumulative Plan R + S + T cleanup:
- R: 35 PE + 17 V2 + 4 V1 + ~600 cascade (52 + 600 = 652 rows)
- S: 4 workflow + cascade (4 + ~20 = 24 rows)
- T5: 7 rows direct + cascade child (~7 + ~30 = 37 rows)
- T flag: DbInitializer permanent disable demo seed
- TOTAL: ~713 rows wiped + flag persist active

Stats final S23 t10:
- 31 mig · 59 tables · ~145 endpoints · 34 FE pages
- 111 test unchanged · 47 gotcha · 20 memory · 6 skills
- 4 sub-agents · backup rollback ready
- **0 PE + 0 workflow + flag disable seed** UAT permanent clean slate

Bro Designer setup workflow mới from scratch khi UAT continue — KHÔNG còn
auto re-seed contaminate. Plan B Contract V2 wire next HIGH priority.
