re: the GP_MAIN_GAME unnamed block -- 333 of 337 already owned, 4 genuinely new

All six language copies carry the identical 337 unnamed IDXD hashes.  Partitioned
by record-name shape (53 shapes), 333 map onto families the corpus already
documents: 131 weapon datasheets, 114 unit datasheets, 64 unit Faces tables, 10
unit message sets, 8 chatter rule tables, 5 enumerations/formations/placement.

114 is exactly the corpus's unit count (43 Craft + 71 Vessel) -- these are the
tables the corpus has always worked with, reached by SHAPE because they have no
names.  Naming them adds nothing.

The Enumerate object in each GP_MAIN_GAME_* is EMPTY, zero fields, which is why
route 2 named 1283 entries in DefTables and 0 here.

The 4 unclassified objects are new -> docs/re/structures/player-tuning-tables.md:
the analog stick response curves (8 axes, 11 samples + a named Count = 11, tested
8/8; yaw/roll/throttle are the identity ramp, the shaping is all on pitch and the
camera axes; adv_yaw is non-monotone and unexplained), the player craft's flight
envelope (Booster, 50 fields -- the player side of the AA_/AV_ pair documented
for NPCs -- plus TacticalManeuver, SpecialAttack + three gauge bands,
SpecialWeapon, Misc), the Stage 16 boss (identified by Shell_S16Boss_* ids;
Guardian HP 65000, Core 42000), and one unidentified Generic naming eff_n0071.

New regenerator main_game_unnamed.py, 112-line artefact, byte-identical across
two runs; the other twelve artefacts verify unchanged.

+## ✅ 2026-08-27 — the `GP_MAIN_GAME_*` unnamed block: 333 of 337 already owned, 4 genuinely new
+
+Item (a). New regenerator `tools/re-capture/main_game_unnamed.py` →
+`docs/re/data/main-game-unnamed.txt` (112 lines, byte-identical across two runs).
+
+✅ **Control first:** all six language copies carry the **identical 337 unnamed
+IDXD hashes**, so this is one set, not six.
+
+✅ **By record-name shape (53 shapes), 333 map onto documented families:** 131
+weapon datasheets (`weapon-datasheet-static.md`), **114 unit datasheets**, 64
+unit `Faces` tables (`unit-datasheet-static.md`), 10 unit message sets + 8
+chatter rule tables (`preset-message-rules.md`), 5 enumerations/formations/
+placement (`stage-mission-tables.md`, `weapon-struct-runtime.md`).
+
+🔑 **114 is exactly the corpus's unit count** (43 `Craft` + 71 `Vessel`) — these
+are the tables the corpus already works with, reached **by shape because they
+have no names**. Naming them would add nothing.
+
+⚠️ **The `Enumerate` object in each `GP_MAIN_GAME_*` is EMPTY** — zero fields.
+That answers the open sub-question: it declares nothing, which is why route 2
+named 1 283 entries in `DefTables` and 0 here.
+
+✅✅ **The 4 unclassified objects are new** → new doc
+`docs/re/structures/player-tuning-tables.md`:
+1. **`955ca077` — the analog stick response curves.** 8 `AnalogRevice_*` records
+   (yaw/pitch/roll/throttle/adv_yaw/adv_roll/eye_yaw/eye_pitch), each **11
+   positional values + a named `Count = 11`** — ⚠️ the `Count`-names-the-group
+   guess was TESTED and holds **8/8**. **yaw, roll and throttle are the identity
+   ramp**; the shaping is all on pitch and the camera axes. 🟡 `adv_yaw` peaks at
+   sample 6 and falls back to 0.208 — not a deflection curve; unexplained. Plus a
+   `Tweak` record with deadzones (`mov_stick_play 5000`, `eye_stick_play 6000`).
+2. **`890e1be4` — the player craft's flight envelope.** `Booster` (50 fields) is
+   the *player* side of the `AA_`/`AV_` pair `unit-datasheet-static.md`
+   documents for NPCs, with afterburner twins; `MaximumVelocity 2100`,
+   `CruisingVelocity 612`. Plus `TacticalManeuver` (the `Turn180`/roll evades
+   whose morph poses the mesh work already found), `SpecialAttack` +
+   `SpecialAttackGauge_1/2/3`, `SpecialWeapon`, `Misc`.
+3. **`0202269d` — the Stage 16 boss**, identified by its own shell ids
+   (`Shell_S16Boss_AAGun`/`_Laser`/`_HBeam`); `Guardian` HP 65 000, `Core` 42 000.
+   Cross-checks the `IsBoss16Enable` hook in `stage-settings-table.md`.
+4. 🟡 **`a6c6c79b`** — one `Generic` record, one field named `eff_n0071`, empty
+   value. Not identified.
+
+🟡 Not settled: the `Tweak` units are inferred from magnitude, not read from a
+consumer; `adv_yaw`'s meaning; object 4. **No loader was located for any of the
+three new objects** — this is a data-side characterisation only, so which code
+reads the curves is open.
