Put a cash-flow bridge YOU computed onto the cash-flow waterfall card. **This tool measures nothing.** It takes the four terms of a bridge and the gap between them as input, draws the waterfall, and returns them. Call it only after you have read the opening and closing positions and summed the window's flows yourself — never to "get" a bridge. A bridge rests on one law: the opening, plus the inflows, minus the outflows, lands on the closing. The closing is measured on its own rather than summed from the flows, so the law is a check rather than a given. State the gap as `unexplained` and the tool verifies the five figures add up; state figures that do not and it refuses. REQUIRED: - `currency` — every figure below is in it, each converted before you stated it - `period_start`, `period_end` — the inclusive calendar days the flows cover - `opening` — `amount` (SIGNED, a workspace can be overdrawn), `as_of` (the day before `period_start`), and `derived` (true only when you solved it from the law because the reading could not be taken) - `inflows`, `outflows` — gross magnitudes, both positive; the direction lives in which bar they are - `unexplained` — the SIGNED gap `closing - (opening + inflows - outflows)`, computed from the figures as you rounded them; zero when they meet - `closing` — `amount` (SIGNED) and `as_of`, the moment the reading was taken - `reconciles` — true when the gap is inside the tolerance below, false when it is past it - `partial` — true when any term is incomplete: an anchor some accounts had no reading for, flows with rows no owned account could be placed against, rows that could not be read, or a currency with no rate. A cut-short read returns no rows and stops the run before this call The tolerance is the product's own: 1% of the closing position's size, never less than 1 in the base currency. A bridge that does not reconcile draws an Unexplained bar between the outflows and the closing; one that does draws none. REFUSED rather than rendered, each because your own figures disagree: - five figures that do not add up to within a cent - `reconciles: true` with a gap past the tolerance, or `false` with one inside it - a negative `inflows` or `outflows`; each is a magnitude, so a negative one was re-signed - an opening not dated the day before `period_start` - a window ending more than a day from the day the closing was read - a window that starts after it ends, or a date that names no real day - a derived opening with any gap, on a partial read, or over a window with no flows - a closing `as_of` in the future When the token authorizes one workspace, call this directly — no other tool call is needed first. When it authorizes several, this read will not guess which one you mean: pass `workspace_id` on the call.
