 🟡 Not settled: what `EX` stands for; the two unnamed `_Test` variant objects;
 what `Placement_*`/`RouteTest_*` are for.

+## ✅🔴 2026-08-28 — `EnumWeapon_EX5.tbl` adds exactly one weapon, and a tutorial expectation is refuted
+
+Item (a): diff S28's bespoke weapon table against the common one.
+
+✅ **The disc has exactly three weapon tables**, and each is a **single
+`EnumWeapon` record whose *field names* are the weapons** — the `Enumerate`-style
+declaration shape again:
+
+```
+EnumWeapon_Test.tbl       126 names
+EnumWeapon_EX5.tbl        127 names  = the same 126, same order, PLUS one
+EnumWeapon_Tutorial.tbl     9 names  = a strict subset of Test
+union                     127
+```
+
+**The whole of S28's bespoke table is one extra weapon:
+`Weapon_TCAF_Ship_AAGun_EX5`.** Zero removals, identical order on the shared 126.
+
+✅ **That explains one of [[weapon-struct-runtime]]'s five "never instantiated"
+disc records** — the AA-gun variant is declared by `EnumWeapon_EX5.tbl` only, and
+that table belongs to **S28 alone**, which the captured save was not playing.
+
+🔴 **And it refutes that document's expectation.** It says "Running the tutorial
+should instantiate the `_Ttrl` pair". It will not: `EnumWeapon_Tutorial.tbl`'s
+nine names are `Weapon_NULL`, `Weapon_ADAN_Puppy_NoseGun`,
+`Weapon_DSaber_P_wep_{01_Beam,02_Missile,58_Laser}` and
+`Weapon_TCAF_DeltaSaber_{Beam,Cannon,Missile,ASMissile}` — **neither
+`Weapon_TCAF_DeltaSaber_NoseGun_Ttrl` nor `_Laser_Ttrl` is among them.** Four of
+the five uninstantiated records (`_NoseGun_Ttrl`, `_Laser_Ttrl`, `_NoseGun_None`,
+`Weapon_ADAN_Attacker_S_GunTurret`) are **declared by no weapon table on the
+disc at all** — a static answer to a question the runtime capture left open.
+
+❔ **`EX` is still not identified**, but it is narrowed hard: the entire content of
+S28's own weapon table is a single `_EX5` AA-gun variant, and the only other
+`_EX5` name on the disc is `UN_f001_TCAF_DeltaSaber_T_EX5`.
+
+🟡 Not settled: what `EX` stands for; the two unnamed `_Test` variant objects;
+what `Placement_*`/`RouteTest_*` are for.
