FNXC:WorkflowSteps 2026-06-25-00:00 — graph-native progress model (plan U3).
These tests pin the render-state contract that the progress bar / Workflow tab rely on:
- names resolve from result.workflowStepName (no DB-row name lookup), with a humanized node-id fallback;
- a "pending" result with a startedAt and no completedAt is the `running` state, vs bare `pending`;
- advisory_failure (non-blocking) is distinct from failed (blocking) and counts as completed;
- disabled optional steps (absent from enabledWorkflowSteps) never appear in the counter/bar.

THE INVARIANT: the running-gate badge appears in the board's OWN review lane.

CENSUS-INVISIBLE, in a HALF-CONVERTED file. `REVIEW_LANE_COLUMNS` is a `Set` literal — a definition,
not a comparison — sitting under a Plan Review badge whose own column restriction had already been
removed. One converted badge and one unconverted one, deciding sibling questions about the same card.

Keyed on the literal, the code-review / browser-verification / post-merge badges never appeared on a
renamed board: the gate WAS running and the card showed nothing, which reads as an idle card rather
than a missing badge. Cosmetic in consequence, but it is the surface an operator watches to know a
review is in flight.

The caller is wired in the same change — `ListView` already owns `columnFlagsById`, so the resolved
answer was one lookup away. An unwired parameter is the class this program's caller audit found five
times; adding a sixth would have been careless.

REVERT PROOF, measured: restore the literal gate and the renamed-lane case returns undefined.
