---

1. Package boundary

• SKU: SC-FIN / PKG-FIN-W11
• Installer: scola_bundle_finance → scola_account
• Prerequisites: W00 PASS; Core company chart/journal baseline
• SC-FEES: separate SKU; /api/v1/finance/accounting/* remains fail-closed per T6B-FEES #22–23
• SC-BOS / SC-OPS bridges: not required for bounded W11 PASS

2. Manual journal entry (POS)

Authorized actor with accounting.journal.view (or manage caps) may:

1. Create move_type=entry with balanced line_ids (debit = credit)
2. Post via /api/v1/accounting/moves/action action=post
3. Observe state=posted and single ledger effect

Forbidden: unbalanced create that reaches posted.

3. Posted immutability (STA)

From	To	Allowed
draft	posted	yes via action=post
posted	draft	no
posted	deleted	no
posted	silent write	no

Direct write({'state': ...}) bypass is stripped server-side; posted write returns validation error.

4. Tenant scope (TEN / SCP)

• All move/journal detail/write/delete/action validates company_id ∈ user allowed companies
• Foreign-company IDs return not_found (no existence leak)
• Journal list scoped to company domain

5. Authorization (NEG)

Users without accounting capabilities cannot list/create/post moves (capability_denied / access_denied).

6. Cross-module (XMD)

• Canonical accounting surface: /api/v1/accounting/* gated by scola_account + SC-FIN entitlement
• SC-FEES finance accounting endpoints remain excluded/disabled independent of SC-FIN
• No automatic Fees payment → journal posting in this wave

7. Explicit deferrals

Item	Track
Maker-checker / payment approval SoD	Post-W11
Bank reconciliation / assign outstanding	Post-W11
Full reversal wizard UX	Post-W11 (API reverse exists but not certified)
Fees→Finance bridge posting	Post-W11 bridge wave
Treasurer FE dashboard Playwright	Optional surface
