# Rehost Queue Archive

This directory preserves older queue snapshots and long-form implementation notes that are still
useful as evidence, but should not stay in the short active queue file.

- `archive-2026-04-19.md`: preserved detailed queue snapshot from the pre-index cleanup.
- `engine-types-parser-semantics-2026-04-21.md`: current static parser frontier for the
  `engine_types` family, including the grounded `.car` fixed slots, guarded `.lco` companion/body
  slots, and the remaining semantic questions around `.cgo`.
- `format-inventory-2026-04-21.md`: current file-format inventory under `rt3/` and `rt3_105/`,
  including the RT3-native families we still do not parse.
- `locomotive-descriptor-tails-2026-04-21.md`: checked `.gms + .gmx` local locomotive catalog
  census and the remaining external-corpus blocker around `Class QJ`, descriptor `452`, and the
  upper descriptor bands.
- `periodic-company-control-lane-2026-04-21.md`: checked compact-dispatch/control-lane evidence
  for the active periodic-company queue head, including the top ordinary nondirect cluster carrier
  maps.
- `tier2-candidate-row-families-2026-04-21.md`: checked candidate-table row-family, trailer-family,
  header-cluster, and crossover carrier-map split for the active Tier-2 `0x00412d70` queue head.
- `tier2-rebuild-sequencing-2026-04-21.md`: checked late bringup sequencing across
  `0x00435630 / 0x00412d70 / 0x00412fb0 / 0x00412c10` for the active Tier-2 queue head.
- `tier2-selector-byte-sources-2026-04-21.md`: checked stock `BuildingTypes` selector-byte and
  alias-root evidence for the active Tier-2 `0x00412d70` queue head.
