## listTreasuryAssumptions

`GET /treasury/assumptions`

Operation ID: <code>listTreasuryAssumptions</code>

**Authentication:** <code>&#95;&#95;Host-klineo&#95;session</code> cookie (<code>sessionCookie</code>)

Private issuer-declared planning assumptions tied to one acknowledged reconciliation. Writes require current workspace treasury authority and recent authentication. Creation rechecks live source authority; revisions preserve exact historical source bindings and do not assert current cash applicability. Exact token units come from server records. Immutable revisions preserve attributed history. Declarations never establish verified expense completeness, actual receipts, spendability or financial authority.

## reviseTreasuryAssumptions

`POST /treasury/assumptions/{id}/revisions`

Operation ID: <code>reviseTreasuryAssumptions</code>

**Authentication:** <code>&#95;&#95;Host-klineo&#95;session</code> cookie (<code>sessionCookie</code>)

Private issuer-declared planning assumptions tied to one acknowledged reconciliation. Writes require current workspace treasury authority and recent authentication. Creation rechecks live source authority; revisions preserve exact historical source bindings and do not assert current cash applicability. Exact token units come from server records. Immutable revisions preserve attributed history. Declarations never establish verified expense completeness, actual receipts, spendability or financial authority.
