The two V9 follow-ups, both proven live on the sandbox.
- creditnote-create.sh: `kind:"supplier"` makes an avoir fournisseur on
/supplierinvoices (type=2 + fk_facture_source, carries ref_supplier); default
customer path unchanged. Proven: customer AVC002 (-240) + supplier AVF2026001
(-144, ref_supplier carried, linked to source, validated).
- bank-accounts.sh + `arcodange sandbox accounts`: list bank accounts (id/label/
bank) so a payment can pick its account_id. Needs `banque lire` (rights 111),
now added to the provisioner's WRITE_IDS so fresh runs include it; the existing
ai_agent_sandbox user was granted it live. GET /bankaccounts now returns the 3
accounts (QONTO, WISE EURO, Compte Courant Asso).
- SKILL.md: supplier-avoir example + accounts helper + updated banque-lire note.
