re: decode the UnitGroup squadron roster, and correct yesterday's container reading
stage\UnitGroup_S<NN>.tbl is now fully readable. A squadron record is Count
member tuples -- (unit model, message set, n, identity/nameplate) -- followed by
five named fields: Count, SideID, AIID, FormationID, DisableInterval. The
property entries carry their own field names inline, so the tag hash never has
to be inverted.
Two independent self-checks validate it corpus-wide, 1160/1160 each across all
28 stage tables on the disc:
- the length identity len(fields) == Count * 4 + 5, which is what pins the
member-tuple width at 4 and the named-field count at 5;
- agreement with the file's own Enumerate_Squadrons roster, which maps record
key to squadron id independently of the per-record string offset.
Adds tools/re-capture/unitgroup.py (pure static, runs no emulator) with a
--all --check self-check mode, and commits the Stage 02 dump as evidence.
Corrections to the container layout written yesterday, all three wrong:
- the 20-byte "(tag, 0, 0, count, size) section header" does not exist. It
was the file's last 16-byte record followed by a plain npool word. The
corrected layout is uniform across all 28 files; the old one failed on 9.
- squadron ids do not use a separate string base. Every offset in the file is
relative to the one string pool. The earlier "109 of 111" score was an
artefact of the uniform 7-byte id stride and had silently shifted every
name by three entries, which is why 17 TC*-named squadrons came out as
SideID=ADAN. The roster record refuted it outright.
- the roster is not always the last record; 9 stages put it elsewhere, so it
is found by its missing Count.
Refuted and kept: the 4-byte record key is not the squadron id's name hash
(0 of 112).
Not settled: what the key encodes, the member tuple's third field n, and where
the arrival interval values live. DisableInterval is only a per-squadron flag
(Yes for 31 of 1160); the durations, triggers and arrival positions are not in
this file. Formation_*.tbl and EnumSquadron_Test.tbl are next.

🔴 Refuted along the way: the 16-byte record key is **not** the squadron
|
||||
ID's name hash (0 of 112).
|
||||
|
||||
**First step (next):** read the `UnitGroup` per-record payload — three u32s per
|
||||
entry — and find where the interval *values* live (the file's second section,
|
||||
`Formation_*.tbl`, or `EnumSquadron_Test.tbl`). Also: S17–S23 have no stage
|
||||
record in `GP_MAIN_GAME_E.pak`; find where they are.

`tools/re-capture/unitgroup.py`, Stage 02 dump committed at
|
||||
[`data/unitgroup-s02.txt`](data/unitgroup-s02.txt). A squadron record is
|
||||
`Count` member tuples — (unit model, message set, `n`, identity/nameplate) —
|
||||
followed by five named fields `Count / SideID / AIID / FormationID /
|
||||
DisableInterval`. Validated corpus-wide by two independent self-checks, each
|
||||
**1160/1160** across all 28 stage tables: the `Count*4+5` length identity, and
|
||||
agreement with the file's own `Enumerate_Squadrons` roster.
|
||||
🔴 Two refutations recorded: the record key is **not** the squadron-ID name
|
||||
hash, and an earlier "109/111" reading of the squadron-id string base was an
|
||||
artefact of the uniform 7-byte id stride (it shifted every name by three).
|
||||
|
||||
**First step (next):** find where the arrival *interval values* live.
|
||||
`DisableInterval` is only a per-squadron flag (`Yes` for 31 of 1160); the
|
||||
durations, spawn triggers and arrival positions are not in `UnitGroup`. The
|
||||
stage record names two untouched candidates: `Formation_*.tbl` (formation
|
||||
geometry, possibly its timing) and `EnumSquadron_Test.tbl`. Also still open: the
|
||||
4-byte record key, the member field `n`, and the missing S17–S23 stage records
|
||||
(S17 has no `UnitGroup_S17.tbl` either, so the whole stage is absent from
|
||||
`GP_MAIN_GAME_E.pak`).

The file is a multi-section IDXD container, and `pak dump`'s current labels for

it are wrong — it prints the first section's key as "schema".
|

**Superseded.** An earlier draft of this section described a multi-section
|

container with a 20-byte `(tag, 0, 0, count, size)` header at `0x708`, 112
|

records, and a separate squadron-id string base. That reading was wrong on all
|

three points: the "header" was the file's last 16-byte record followed by a
|

plain `npool` word, and it failed to parse 9 of the 28 stage tables.

increasing for exactly 112 entries and the run breaks at `0x708`, where the next

section header sits.

The corrected, uniform layout — header, 16-byte records, a 12-byte property

# `stage\UnitGroup_S<NN>.tbl` — the per-stage squadron roster
|
||||
|
||||
Status: ✅ container format and field semantics, validated across all 28 stage
|
||||
tables present on the disc; 🟡 one member field; ❔ the record key and the
|
||||
arrival-interval *values*.
|
||||
|
||||
Reached from the per-stage definition record's `EnumerateSquadron` field — see
|
||||
[stage-definition-table.md](stage-definition-table.md). Tool:
|
||||
`tools/re-capture/unitgroup.py` (pure static; runs no emulator).
|
||||
|
||||
```
|
||||
python3 tools/re-capture/unitgroup.py S02 # full roster
|
||||
python3 tools/re-capture/unitgroup.py --all --check # self-check every stage
|
||||
```
|
||||
|
||||
A committed dump of Stage 02 is at [`../data/unitgroup-s02.txt`](../data/unitgroup-s02.txt).
|
||||
|
||||
## ✅ Container

||||

|

```
|
||||
|
||||
**Every offset in the file is relative to `STR`**, the string-pool base. A
|
||||
record's fields are pool entries `[field_lo, field_hi)`. An entry with
|
||||
`name_off == 0xffffffff` is *positional*; otherwise the entry carries its own
|
||||
field name inline, so the table is self-describing and the tag hash never has to
|
||||
be inverted.
|
||||
|
||||
Exactly one record per file is not a squadron: it is the **`Enumerate_Squadrons`
|
||||
roster**, whose entries map `key -> squadron id` for every other record. It is
|
||||
usually the last record but not always — in S05, S06, S07, S08, S09, S11, S13,
|
||||
S28 and S29 it sits elsewhere, so find it by its missing `Count`, not by
|
||||
position.
|
||||
|
||||
## ✅ A squadron record
|
||||
|
||||
Five named fields, always present and always these five:
|
||||
|
||||
| field | values |
|
||||
|---|---|
|
||||
| `Count` | 1 (×1082), 2 (×50), 3 (×8), 4 (×20) |
|
||||
| `SideID` | `ADAN` (745), `TCAF` (294), `Neutral` (121) |
|
||||
| `AIID` | 31 distinct, e.g. `AI_ADAN_CraftSquadron_Veteran`, `AI_TCAF_BirdFlight`, `AI_ADAN_Fleet`, `AI_Structure`, `AI_TraceRoute` |
|
||||
| `FormationID` | e.g. `Formation_4_Bird`, `Formation_ADAN_Turret07_30`, `Formation_1_only` |
|
||||
| `DisableInterval` | `No` (1129), **`Yes` (31)** |
|
||||
|
||||
…preceded by `Count` **member tuples** of four positional entries:
|
||||
|
||||
```
|
||||
(unit model, message set, n, identity)
|
||||
```
|
||||
|
||||
* unit model — 122 distinct, and they are our XBG7 mesh names:
|
||||
`UN_f001_TCAF_DeltaSaber_T_Player`, `UN_e010_ADAN_Attacker_S`,
|
||||
`UN_e007_ADAN_Turret`, `UN_bf001_TCAF_SchlosBase`.
|
||||
* message set — the squadron's radio chatter, e.g. `MessageSet_Ellen`,
|
||||
`MessageSet_ADAN_plA`.
|
||||
* `n` — 🟡 **unidentified**; integer 1…30, dominated by 1 (735) and 9 (197).
|
||||
It is *not* the `_NN` suffix of `FormationID` (`Formation_ADAN_Turret07_30`
|
||||
pairs with `n = 9`). Plausibly a spawn or wing size, untested.
|
||||
* identity — 63 distinct: named pilots (`ELLEN`, `SANDRA`, `RAYMOND`, `YOJI`),
|
||||
ship nameplates (`NP_Charon`, `NP_Amalthea`, `NP_Olympus`), carrier tags
|
||||
(`Carrier_ADAN01`), cargo tags (`CARGO_1`), or empty.
|
||||
|
||||
Worked example — Stage 02, squadron `TCN004`, the player's own flight:
|
||||
|
||||
```
|
||||
TCN004 TCAF Count=2 DisableInterval=No Formation_2_Rhino1 AI_TCAF_RhinoFlight
|
||||
unit=UN_f001_TCAF_DeltaSaber_T_Player msg=MessageSet_Katana n=1 id=Character_Player_Test
|
||||
unit=UN_f001_TCAF_DeltaSaber_T msg=MessageSet_Ellen n=1 id=ELLEN
|
||||
```
|
||||
|
||||
## ✅ Two independent self-checks, both corpus-wide
|
||||
|
||||
1. **`len(fields) == Count * 4 + 5`** — holds for **1160 of 1160** squadrons
|
||||
across all 28 stage tables. This is what pins the member-tuple width at 4 and
|
||||
the named-field count at 5; it was not assumed.
|
||||
2. **Roster agreement** — the `Enumerate_Squadrons` record's `key -> id` mapping
|
||||
agrees with the name each record resolves independently through its own
|
||||
`squadron_off`, for **1160 of 1160**.
|
||||
|
||||
S17 has no `stage\UnitGroup_S17.tbl` in `GP_MAIN_GAME_E.pak`, matching the
|
||||
missing S17 stage record.
|
||||
|
||||
## ❌ Refuted along the way
|
||||
|
||||
* **The record key is not the squadron id's name hash.**
|
||||
`name_hash("TCN001") = 0xd639f1a4`, but the keys run
|
||||
`0x659aff47, 0x659b0046, 0x669b0047, …` — 0 of 112 match. What the key encodes
|
||||
is still ❔. Its byte structure (`b0` ramping, `b2` taking small signed values)
|
||||
looks like a packed tuple, untested.
|
||||
* **Squadron ids do not use a separate string base.** An earlier reading here
|
||||
put them at `STR + 0x15` and scored "109 of 111", which looked like a near-fit
|
||||
but was an artefact of the uniform 7-byte id stride — it silently shifted
|
||||
every name by three entries (record 0 read as `ADN104` instead of `ADN101`,
|
||||
and 17 `TC*`-named squadrons came out with `SideID = ADAN`). The roster record
|
||||
refuted it outright, and with the correct base — plain `STR` — agreement is
|
||||
111/111. The lesson is that a 98 %-looking score on a self-consistent stride
|
||||
is not evidence; the roster was an independent oracle and should have been
|
||||
consulted first.
|
||||
* **The 20-byte "section header"** described in an earlier draft of
|
||||
[stage-definition-table.md](stage-definition-table.md) does not exist. What
|
||||
looked like `(tag, 0, 0, count, size)` was the file's last 16-byte record
|
||||
followed by the `npool` word. The corrected layout above is uniform across all
|
||||
28 files, which the earlier reading was not — it failed on 9 of them.
|
||||
|
||||
## What is still open
|
||||
|
||||
* The meaning of the 4-byte record key.
|
||||
* The member tuple's third field `n`.
|
||||
* **The interval values.** `DisableInterval` is a per-squadron *flag* and 31
|
||||
squadrons set it, but the interval durations, spawn triggers and arrival
|
||||
positions are not in this file. The next places to look are
|
||||
`Formation_*.tbl` (the formation geometry and possibly its timing) and
|
||||
`EnumSquadron_Test.tbl`, both named by the stage record.
