+## Foreign and unidentified groups
+
+The legacy text format does carry top-level `<Race> Groups` blocks
+and a single `Unidentified Groups` block, both outside the battle
+rosters — earlier parser revisions silently dropped them. F8-05
+wires them up:
+
+- **`OtherGroup[]`** — every `<Race> Groups` section outside a
+  `Battle at` block contributes one entry per row. The legacy row
+  is `# T D W S C T Q D P M` (count, class, drive/weapons/shields/
+  cargo tech, cargo type, load, destination, power=drive·20 — not
+  retained, mass). The destination resolves against the parsed
+  planet tables (`Your Planets`, `<Race> Planets`, `Uninhabited
+  Planets`); rows whose destination is invisible to the local
+  player are dropped — preferable to fabricating a number. The
+  legacy row carries no origin / range columns, so foreign groups
+  surface as stationed at the destination (origin / range nil).
+- **`UnidentifiedGroup[]`** — the `Unidentified Groups` section
+  carries `X Y` floats only. Each row maps directly onto
+  `UnidentifiedGroup{X, Y}`; no planet resolution needed.
+
 ## Skipped sections (today)
 
 These exist in legacy reports but cannot be derived from the legacy
 text format at all. Each could become in-scope if a strong enough
 reason arises (see "Adding a new field" below).
 
-- `OtherGroup[]` — no top-level legacy section. Foreign groups appear
-  only inside battle rosters; the synthetic JSON emits
-  `otherGroup: []`.
-- `UnidentifiedGroup[]` — no legacy section at all; synthetic JSON
-  emits `unidentifiedGroup: []`.
 - Cargo routes — no dedicated section in the legacy text format; the
   synthetic JSON emits `route: []`. The UI's overlay path
   (`applyOrderOverlay`) supports running on top of an empty `routes`.
