building-growth policy, and recent profit history instead of leaving that policy on shell-side
dialog notes. `simulation_service_periodic_boundary_work` is now beginning to use that same owner
surface too: the runtime chooses one annual-finance action per active company and already commits
the shellless dividend-adjustment, stock-repurchase, stock-issue, and bond-issue branches by
mutating owned dividend, company stat-post, outstanding-share, issue-calendar, and live bond-slot
state instead of stopping at reader-only diagnostics.
the shellless creditor-pressure-bankruptcy, deep-distress-bankruptcy, dividend-adjustment,
stock-repurchase, stock-issue, and bond-issue branches by mutating owned company activity,
dividend, company stat-post, outstanding-share, issue-calendar, and live bond-slot state instead
of stopping at reader-only diagnostics.
The same seam now also carries the fixed-world building-density growth setting plus the linked
chairman personality byte, which is enough to run the annual stock-repurchase gate as another
pure reader over owned save-native state instead of a guessed finance-side approximation.
