# Periodic Company Control Lane (2026-04-21)

This note preserves the checked evidence behind the current periodic-company queue head, so the
short queue can stay focused on the remaining owner question.

## Checked Export

- `artifacts/exports/rt3-1.06/compact-event-dispatch-cluster-counts.json`

Current checked corpus totals:

- `maps_scanned = 41`
- `maps_with_dispatch_strip_rows = 38`
- `dispatch_strip_record_count = 318`
- `dispatch_strip_records_with_trigger_kind = 0`
- `add_building_dispatch_record_count = 10`

The add-building subset is still only `7` descriptor keys:

- `Barracks`
- `Bauxite Mine`
- `FarmGrain`
- `Furniture Factory`
- `Logging Camp`
- `Port01`
- `Warehouse05`

## Concrete Carrier Maps

The checked export already keeps the strongest carrier maps visible:

- `Texas Tea.gmp` for `548 Add Building Port01`
- `Louisiana.gmp` for `563 Add Building Warehouse05`
- `Alternate USA.gmp` for the repeated `FarmGrain` / `Logging Camp` `ge34` family
- `Chicago to New York.gmp` and `Pacific Coastal.gmp` for the mixed `[-1:4]` cluster

The widened full-corpus cluster surface now keeps the strongest non-add-building families visible
too:

- `dispatch_signature_condition_cluster_occurrence_counts`
  - `36` for `nondirect-ge1e-h0001-0360-0004-0100-0200-p0000-0000-0000-ffff :: [864:4]`
  - `27` for `nondirect-ge1e-h0001-ffff-0004-0000-0200-p0000-0000-0000-ffff :: [-1:4]`
- `dispatch_signature_condition_cluster_descriptor_keys`
  - the `36`-occurrence cluster is the broader variable/status family over
    `Economic Status` plus `Game/Company Variable 1..4`
  - the `27`-occurrence `[-1:4]` cluster still mixes those variable families with the two checked
    add-building descriptors `Barracks` and `Bauxite Mine`
- `dispatch_signature_condition_cluster_map_paths`
  - the `36`-occurrence cluster spans `18` maps including `Britain.gmp`,
    `Chicago to New York.gmp`, `Crossing the Alps.gmp`, and `Eastern China.gmp`
  - the `27`-occurrence `[-1:4]` cluster spans `14` maps including `Alternate USA.gmp`,
    `Chicago to New York.gmp`, `Coast to Coast.gmp`, and `Go West!.gmp`
- the checked periodic-company trace now mirrors the strongest four of those full-corpus families
  directly through
  `near_city_acquisition_nontransport_top_dispatch_signature_condition_clusters`, so the active
  queue head is no longer backed only by the export file

## Grounded Boundary

The active strip is still:

- `0x00444d92 -> 0x00432f40(kind 8) -> 0x004323a0 -> 0x00431b20`

The checked boundary around that strip is now narrow:

- ordinary loaded nondirect rows already reach the `0x00431b20` mutation strip at scale
- the export still shows no recovered trigger kind for any of those checked rows
- the remaining question is therefore not whether ordinary loaded rows can reach the compact
  dispatch strip, but where they acquire or bypass the missing trigger-kind control lane before
  placed-structure mutation opcodes run

## Closest Already-Grounded Retags

The checked periodic-company service trace now also exposes these grounded control-lane neighbors
directly through:

- `near_city_acquisition_nontransport_late_bringup_candidate_branches`
- `near_city_acquisition_nontransport_explicit_trigger_kind_retags`

The current artifact notes and trace now agree on the same two explicit late retag writers away
from ordinary reload:

- `SP - GOLD` branch at `0x00443526`
  - rewrites `[event+0x7ef]` from `1 -> 5`
- `Labor` branch at `0x00443601`
  - rewrites `[event+0x7ef]` from `0 -> 2`

So the next non-hook question stays above those already-known title or scenario-specific retags:

- which late bringup branch between ordinary reload `0x00433130` and final kind-`8` service
  `0x00432f40` materializes the live mutation-capable ordinary rows
