v1.5.2 (2026-10-08)

• Fixed: pressing Enter above a block of line references could
  leave them stale or drag one backward. On the Mortgage template,
  two Enters above the headline turned &25/&26/&27/&28 into
  &26/&27/&28/&27 instead of &27/&28/&29/&30 - the summary lines
  then answered with the wrong derivation rows. Root cause: when
  references target CONSECUTIVE lines, the renumbering plan chains
  (each relabel's new label is the next mark's existing key), and
  the plan was applied sequentially into a label-keyed table, so
  every step silently evicted the next mark. The plan is now applied
  as the simultaneous rename it always meant to be, through a shared
  helper both the app and the tests exercise. Found by Brandon on
  the Mortgage template the same night it shipped; diagnosed by a
  three-agent research wave that converged on the same four lines of
  page.rs from three directions.
