# Rehost Queue

Working rule:

- Do not stop after commits.
- After each commit, check this queue and continue.
- Only stop if the queue is empty, you hit a real blocker, or you need approval.
- Before any final response, state which stop condition is true. If none is true, continue.

## Next

- Rehost the outer periodic company-service seam around
  `company_service_periodic_city_connection_finance_and_linked_transit_lanes`, using the now
  save-native side-latch trio `0x0d17/0x0d18/0x0d56` as owned runtime state instead of leaving
  that pass split across annual-finance readers and atlas notes.
- Move the periodic-boundary owner from passive imported side-latch state toward same-cycle
  service-owned refresh or reset behavior, so earlier periodic branches can eventually set those
  lanes before annual finance consumes them.
- Keep widening selected-year world-owner state only when a full owning reader/rebuild family is
  grounded strongly enough to avoid one-off leaf guesses.

## In Progress

- Widen shellless simulation from explicit service commands toward “advance the runtime clock and
  the simulation-owned services advance with it.”

## Queued

- Rehost additional periodic finance/service branches that still depend on frozen world restore
  fields instead of advanced runtime-owned time state.
- Reduce remaining company/chairman save-native gaps that still block standalone simulation
  quality, especially controller-kind closure and any deeper finance/state fields that still rely
  on conservative defaults.
- Rehost bounded live economy owner state beyond selector/catalog/override surfaces when a
  concrete non-shell-owned seam is grounded.
- Keep tightening shell-owned parity families only when that directly supports later rehosting.

## Blocked

- Full shell/dialog ownership remains intentionally out of scope.
- Any candidate slice that requires guessing rather than rehosting owning state or real
  reader/setter families stays blocked until a better owner seam is grounded.

## Recently Done

- Stepped calendar progression now also refreshes save-world owner time fields, including packed
  year, packed tuple words, absolute counter, and the derived selected-year gap scalar.
- Automatic year-rollover calendar stepping now invokes periodic-boundary service.
- Save-native world locomotive policy owner state now flows through runtime restore state,
  summaries, and keyed world-flag execution for the grounded `All Steam/Diesel/Electric Locos
  Avail.` descriptor strip plus the cached available-locomotive rating.
- The selected-year bucket ladder rooted in `0x00433bd0` is now checked in as a static artifact,
  and runtime restore state now derives both the selected-year bucket scalar and the
  `[world+0x0bde]` economic-tuning mirror from owner-family inputs instead of preserving stale
  load-time residue.
- That same selected-year owner family now also rebuilds the direct bucket trio
  `[world+0x65/+0x69/+0x6d]`, the complement trio `[world+0x71/+0x75/+0x79]`, and the scaled
  companion trio `[world+0x7d/+0x81/+0x85]` from the checked-in `0x00433bd0` artifact instead of
  preserving stale save-time residue.
- The save-native company direct-record seam now also carries the full outer periodic-company
  side-latch trio rooted at `0x0d17/0x0d18/0x0d56`, including the preferred-locomotive
  engine-type chooser byte beside the city-connection and linked-transit finance gates.
- That same side-latch trio now also has a runtime-owned service-state map and summary surface,
  so later periodic company-service work can stop reading those lanes directly from imported
  market/cache residue.
- Company cash, confiscation, and major governance effects now write through owner state instead of
  drifting from market/cache readers.
- Company credit rating, prime rate, book value per share, investor confidence, and management
  attitude now refresh from grounded owner-state readers.
- Annual finance service persists structured news events and grounded debt/share flow totals.
