List the categories a reader can exempt from burn over one window, each with the spend exempting it would remove. This is what the exemption card offers; it measures nothing the sum did not already measure.

Each entry in groups is one category's OUTFLOW in the window: category_key (the id an exemption is matched on), label (the category as the product writes it), amount (a magnitude, never signed) and count (the rows behind it). Sorted by amount descending, so the biggest decision reads first. A category with no outflow in the window is NOT listed — exempting it would remove nothing, so it is not a choice.

total is the sum of groups[].amount and nothing else. unclassified_amount and unclassified_count are the outflow this list cannot offer as a choice: rows carrying no category, which no exemption ever matches, and rows whose category is outside the shared vocabulary, which this read cannot name for a reader. The two are reported together because both leave the reader's choices unable to touch that money — not because the same thing is true of them downstream. total + unclassified_amount is the window's whole outflow, so a reader can see what the choices do not cover. State the unclassified figure whenever it is not zero rather than presenting total as the whole window.

Pass the convention you elected for the burn figure itself. The list and the figure have to sit on one election, and this read deliberately does not make a second one.

partial: true means the underlying sum measured nothing, so groups is empty and nothing is known about the window's spend. Say so and offer to try again, rather than presenting an empty list as a decision. unreadable_rows counts rows whose amount could not be read at all; they are in no figure here.

from is inclusive and to is EXCLUSIVE, so a window of whole months passes the first instant of the month after the last one you want. window echoes both back exactly as you sent them.

Internal transfers are already out. This read keeps only the rows with exactly one leg on an account the workspace owns — the same rule the burn applies — so a movement between the workspace's own accounts never appears here.

currency is the one currency every row in the window shares. A window holding more than one, or holding a row that carries none, is REFUSED with success: false and an error saying which: adding two currencies gives a number denominated in nothing, and no field on this result could say it happened. currency is the EMPTY STRING only when the window held no row at all, and then groups is empty and both totals are zero.

The direction convention is elected ONCE over the whole window, never per category. A window whose rows are overwhelmingly negative stores an outflow as a negative amount, and these figures are that branch. A window that stores outflows as positive magnitudes keeps the direction in a field this grouping does not read, and a window that pools both kinds of feed has no single outflow at all — both are REFUSED with an error naming the counts behind the decision, rather than reported as spend.

Take the reader's answer from the card, record it with well_switch_workspace as exempt_categories, and read it back with well_wait_for_selection (kind "exemptions"). The record belongs to this conversation. Another conversation does not read it. Then pass the same keys to well_sum_transactions as exempt_categories to compute the burn without them, and name the exemptions beside the figure so it can be read back.

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.
