re: the last 9 effects are genuinely unshipped; wep_85 accounts for two

EF_IDX_ proved that prefixes exist, so the residual deserved the same treatment
across every package rather than one. Censusing prefixes over all 36
effect-carrying .xpr gives seven in use:

  EF_IDX_       223 names
  mdl_           45
  EF_IDX_mdl_    45
  VolumeLine_    10
  GN_            10
  GN__            6
  bare           the rest

Testing all nine unlocated names against all seven prefixes: 0 of 9 resolve.

That zero has force where the earlier disc-wide zero did not, and for the stated
reason - the control shows each prefix genuinely carries names the same search
reads (223, 45, 45, 10, 10, 6), so the instrument demonstrably works on the
population it is being asked about. The nine are bound by a datasheet field and
shipped in no package.

Two of them turn out to belong to one cut asset. eff_m010_wep_85 and
eff_m011_wep_85 name a weapon, and the weapon is real in the data:
Weapon_DSaber_P_wep_85_Beam with 24 uses, its Shell_, WeaponCannonName_ and
WeaponShellName_ siblings, and GameModel_eff_m010_wep_85 / _m011_ declaring the
two effects. But the weapon packages stop at 84 - hidden/resource3d/ holds 59
rou_f001_wep_NN.xpr files numbering 00 to 84 with gaps, and no wep_85. So wep_85
is a declared-but-unshipped weapon and its two effects go missing with it.

This does not contradict "every weapon is placed - 131 = 105+22+0+4". That
partition is declared x MOUNTED IN A LOADOUT, which is a different question from
whether a package ships.

Seven remain with no account: eff_e0044, eff_f0002, eff_f0002_barn, eff_h308,
eff_j002_e01, eff_j002_e02, eff_n0071. The .xpr route is now exhausted for them
under every prefix the disc uses; a different container or a runtime generator is
what is left.

All seventeen artefacts byte-identical.
