What

hubspo-query::board::Board implements HubSpot's pipeline board. For each (pipeline, stage) it gives the record count and the amount sum over the records a view's filter keeps.

• Two GroupReduce programs over the composite address pipeline × stages + stage (GroupAddr::Pair). No row ids are materialised and no composite key lane is built.
• Records without an amount are counted but not summed. A stage whose records all lack an amount reads amount: None, never 0; columns() runs both result buffers through normalize_group_sink to make that distinction.
• weighted(amount, probability_bp) is exact: the product is kept in minor units × basis points (i128). Weighting a stage's total therefore equals summing the per-record weighted amounts to the last unit; rounding is left to the display.

The saved-view half of D-QRY-3 is still open: view definitions as data, and sorting. Quack has no ORDER BY (rows come back in storage order), so a table view sorted by a property needs its own decision.

Evidence

tests/board_oracle.rs checks unfiltered, filtered and narrow boards against a plain per-cell tally. The data is 6,000 deals across 3 pipelines × 7 stages: 4 % are deleted, 25 % have no amount, and one stage has no amounts at all.

Disable runs, each with an asserted patch anchor:

disable	tests that went red
sum ignores the amount validity plane	3
empty sum read as 0	2
pipeline / stage swapped	3
zero group universe accepted	1
empty stages reported	1

The last disable stayed green on the first run, because every fixture occupied all 21 stages. I added a narrow-board test, whose own check requires that fewer than half the stages are occupied; with that test in place the disable goes red.

Workspace fmt, clippy (--all-targets --no-deps -D warnings) and tests pass locally. Rebased on main after #20; no other HubSPO-rs PR is open.
