44bdbad2d6 re: every bound effect vs every declared effect; a Shift-JIS dev placeholder
The Explosion substructure's field list was already in the corpus, so the open
part was whether the effect names RESOLVE. Declared x used, sweeping 34 binder
field names (*FxModel*, *EffectName, Effect_*, ShellModel, CoverModel,
SilhouetteModel) against every name declared by a LOD_Effect_<n> or
GameModel_<n> field anywhere on the disc:

                 declared   not declared
  used              172          58
  not used          318           -

490 declared, 230 used. Top binders: Effect_Paralyze 2874, ShellModel 996,
HitFxModel 738, JetFxModel_000 408, MuzzleFlashFxModel_Loop 384.

The 58-cell is almost one field. 53 of the 58 are bound by SilhouetteModel
alone and are all rou_f###_wep* names - the arsenal item silhouettes already
documented in arsenal-item-weapon-chain. They are undeclared because they are
the wrong KIND: each resolves as its own standalone package, rou_f001_wep_01.xpr
and friends, never as a LOD-table entry. Nothing is missing; the sweep was
reading an asset-file name as though it were an effect name. That leaves four
genuinely undeclared effects - eff_e0044, eff_f0002, eff_f0002_barn, eff_h308 -
none of which resolves as a record or field name either.

One "effect name" in that cell is not a name at all. Bound by Effect_Explosion
and Effect_Flare, 72 occurrences = 12 users, its bytes are 95 B6 8E 9A 97 F1 -
Shift-JIS for the word "character string". A developer's placeholder. This
exposes a reader defect worth fixing before these strings reach a port:
unitgroup.py hands the value back as Latin-1 mojibake, so an IDXD string field
can carry Shift-JIS and our decode does not know it.

Following the silhouettes into the ISO tree turned up a convention that IS real:
59 of the 166 .xpr packages end _hangar.xpr, and 59 of 59 have a bare twin of
the same stem. The direct contrast to yesterday's refutation, where _all/_child
was 1 of 166 with a single stem. Suffix conventions in this corpus are worth
testing precisely because they are not all real.

Controls reproduced from the previous iteration: eff_n0071 is declared and used
6x (= one user under the per-pak-copy rule); eff_e0033 is declared and used 0x,
sitting in the 318-cell. That cell is expected rather than alarming - the
EnumLODSet/EnumGameModel family is overwhelmingly equipment, which no unit
datasheet binds.

All fifteen artefacts byte-identical.

15c9e13c12 re: CoverArea is a 6-bit MOUNT mask; the three other turret leftovers closed
Six bits, never more.  Over all 835 turrets: 41 distinct values, max
0x3f, bits 6/7 set on none; per-bit 709/117/274/274/260/237.  0x00 (34)
= the empty Weapon_NULL hardpoints with YawLimit 0; 0x01 alone (439) =
craft hardpoints with YawLimit 2.5/1.0/0; 2-6 bits (362) = warship
mounts with YawLimit 45-180.

It tracks the MOUNT, not the weapon.  UN_e107_ADAN_AAFrigate has eight
identical AAFrigate_AAGun turrets: GN_GunXS_01..04 are 0x1d and 05..08
are 0x2d -- same gun, same YawLimit 120, different mask.  The Battleship
spreads five masks over GN_TGunL_01..05 / GN_TGunM_02..03, all firing
the same CAF_Ship_ASGun.

Which sector each bit denotes is NOT determined; six bits and the name
invite +-X/+-Y/+-Z or six hull faces, but nothing static fixes the
convention.  Not adopted.  Refuted on the way: bits 2 and 3 are not a
mutually-exclusive pair -- 188 turrets set both.

The 26 weapons no turret mounts are a coherent set: 11 _P player
variants, the nose/twin mounts, two _Child sub-munitions, the three
S16Boss_*, three Weapon_Test_*, and ADAN_Attacker_S_GunTurret.

Versatile_NNN ships nowhere -- 0 populated records across all 41
archives, only the ??? template row.

The two units one turret short: both extras are missile mounts with no
Frame.  Elan_EX4 = NoseGun + Missile, both mask 0x01, both frameless;
AAFrigate_EX4 = eight framed guns plus one Ship_AAMissile at 0x0c with
no Frame.  n=2, stated as the observed pattern, not a rule.

New artefact and regenerator; the other nine regenerate byte-identical.

21e710a531 re: the 59-of-131 arsenal question is closed -- an item names a hardpoint
An Arsenal item does not reference a Weapon record.  It references a
Turret_NNN HARDPOINT SLOT on the player craft's own unit table, and the
slot is what carries the WeaponID.  Three hops:

  Arbalest_155KG.PlayerWeapon -> Turret_050  (a slot on
  UN_f001_TCAF_DeltaSaber_T_Player) -> .WeaponID ->
  Weapon_DSaber_P_wep_50_Cannon

Controls, both in the same loop: 0/59 distinct PlayerWeapon values are a
Weapon.ID; 59/59 are a Turret_NNN slot id; the full chain lands on a
Weapon.ID 59/59.  WingmanWeapon resolves identically.  The WEAPONS
roster's 59 = 55 item names + 4 empty-slot sentinels.

Wingmen fly a cheaper gun: following the same 59 slots across craft
variants, the _Player tables give each item its own weapon record (59
distinct) while the AI tables collapse all 59 onto 10 generic classes.
That is most of the 131.

Upgrades yesterday's 'hardpoint catalogue' reading from 21 to adopted,
proved from an independent file, and corrects its '10 distinct WeaponID'
figure -- that was the AI variant, not the player's.

Also adds an __main__ guard to unit_substructures.py so importing
pak_entries from it does not run its report; its artefact is unchanged
and still byte-identical.

4a5e5d55e6 re: the destructible-subsystem model -- a unit's sub-records
The corpus has named these since unit-struct-runtime.md but never
opened them.  Per unit table: Turret_NNN 835 records (max 63 on one
unit), ShieldGenerator_NNN 46, Thruster_NNN 38, Hatch_NNN 26,
Bridge_NNN 25, plus one each of Shield/Mass/SE/Explosion/
StructureCount and NS_Body on 68 of 114.

Turret/ShieldGenerator/Thruster/Hatch/Bridge are ONE record shape: a
shared 19-field destructible-part base (ID, Name, ParentStructureID,
Frame = a mesh NODE name, NomalModel, CollisionModel, Radius, HP, the
four Is* flags, SpreadDamage, damaged/destroy motion + time, and the
three Effect_*), with per-kind extras.  Turrets add WeaponID,
AngularVelocity, YawLimit, PitchLimit_Elevation/_Depression, CoverArea,
IsAuto, HasBarrel and up to 80 CannonModel_NNN/CannonFrame_NNN.  Shield
generators, thrusters and bridges add PowerRatio.  Hatches add
SquadronID, LoadedCount, MaxAvailableCount, TakeoffInterval -- a
carrier's launch bay.

Control 1: StructureCount.<Kind>Count == #<Kind>_NNN records, over 684
comparisons -- 612 equal, 55 "0 declared, one blank placeholder"
(55/55 blank in Name AND NomalModel AND Frame), 11 differ, 6 kind
absent.  All 11 exceptions are Turret and all are declared < records.

Control 2: 835/835 Turret_NNN.WeaponID resolve to an ID in the
131-record Weapon datasheet, zero unresolved; 26 weapons are never
mounted on a turret.

Refuted in the same pass: "the DeltaSaber's 59 non-NULL hardpoints are
the 59-name WEAPONS arsenal roster".  The counts match exactly and the
sets overlap in 0 values -- two namespaces, one coincidence.

New structure doc, artefact and regenerator; other artefacts unchanged.
