T6B/W10 engineering closure packet — 2026-09-23¶

Environment: server worktree /home/scola/odoo
FE branch tip: develop (local edits)
BE branch tip: feature branch + local edits

Claim (honest)¶

Claim	Value
Engineering-ready bounded W10 V1 (tunai + transfer only)	YES — pending QC tip + harness rebind
Midtrans VA / Xendit / DOKU / QRIS / e-wallet in W10	NO — out of scope (GCG partnership)
`CERTIFIED` production baseline	NO
Demo/production promote authorized	NO

Independent auditor + immutable demo candidate + explicit PROMOTE_PRODUCTION remain mandatory before any CERTIFIED/production claim.

See docs/domains/keuangan/T6B-W10-certification-scope-amendment-2026-09-23.md.

SSOT: all PSPs including Midtrans VA out of W10; product vocabulary pointer in Handbook §4.
Gateway hard-fail: ORM + setup API + Odoo views + FE Setup only manual; get_active_midtrans empty; create_va fail-closed; V1_CHANNELS = cash + bank_transfer.
Dual ledger bridge: invoicing a fee schedule ensures scola.w10.bill; parent invoice/list expose bill; pay UI prefers that bill.
User guides: payment copy no longer says “W10”.

Sibling discount on bills: D2 implemented (check/apply + W10 mutation); still needs harness/UAT evidence before production claim
Any payment gateway / VA tranche
Independent re-audit / UAT demo / production promote
Historical schedules without enrollment may still fail ensure-bill (fail closed)
