Research: GATEPal UI, Inventory UI, and Story Chapters

1. GATEPal (in-game journal/PDA) UI structure

What the GATEPal actually is in-game

The handheld GATEPal item opens the Journal tab of the pause/inventory screen. The whole experience is one widget: AbioticFactor/Content/Blueprints/Widgets/Journal/W_Player_Journal_Main (embedded as page "Panel_Journal" of W_PlayerInventory_Main; the nav-bar tab icon is Textures/GUI/Icons/icon_pda). It is not green-on-dark: the PDA screen is a light paper page with near-black ink, dark-green/teal accents, and a cyan title floating on the dark blurred backdrop above the page.

2. In-game inventory UI structure

Main widget: AbioticFactor/Content/Blueprints/Widgets/Inventory/W_PlayerInventory_Main (1920x1080 ScaleBox). Backdrop = BGBlurClickBlocker BackgroundBlur over the 3D world + BG_BlueTint (tint 08FDE3 at 14% opacity) - the signature blue-teal wash. Close button top-right (icon_arrow_left tinted FD7070).

Top-level layout

Weight bar (W_InventoryWeight)

311x14 rounded ProgressBar pair: WeightBar (white fill) + overlaid CurrentItemWeightBar whose fill texture is Textures/WallTrim/T_WallTrim_WarningStripe_Orange (hazard stripes = weight of the hovered/selected item).

3. Story chapters (DT_StoryProgression, 37 rows)

Source of truth: AbioticFactor/Content/Blueprints/DataTables/DT_StoryProgression (full dump in Probe5). Columns per row - there is no description text in the table; the player-facing wording below is synthesized from the wiki's Objectives page and flag names:

• WorldFlag_2_* (DataTableRowHandle) - the WorldFlag that, once present in a region save's WorldFlags array, advances WorldSave_MetaData.StoryProgressionRow to this row.
• StoryImage_18_* (SoftObjectPath) - /Game/Textures/GUI/ServerBrowser/map_* chapter card art (great for the quest UI; e.g. map_office1, map_dflabs).
• DisplayText_17_* (FText) - the region/sector heading shown in-game.
• NumberOfAreasUnlocked_16_* (int) - drives map silhouette stage / unlock count.

The save's StoryProgressionRow stores the row name (e.g. MFBlacksmith). Index = position below (0-based, row order).

#	Row	Region (DisplayText)	Trigger WorldFlag	Card art	Areas	Player-facing description
0	Office	The Office Sector	Office_NewGameStarted	map_office1	1	Containment breach day. You wake up in the Office Sector, scavenge your first tools, let Dr. Jager into the cafeteria and report to sector security officer Warren.
1	Office2	The Office Sector	Office_InformationFound	map_office2	2	You've learned the only way out is through Manufacturing - but a forklift holding the blast door needs Power Cells. Grayson points you to the energy research team.
2	Office3	The Office Sector	Office_ThirdFloorReached	map_office3	4	You reach the Office Sector's third floor and convince Archie Roberts (or Regal) to open Silo 3, where the Power Cells were taken.
3	Flathill	The Office Sector	Office_Silo3Opened	map_office3	5	Silo 3 is open. All signs point through the portal inside: step into Flathill, a fog-drowned suburban anomaly, to recover Power Cells.
4	PostFlathill	The Office Sector	Fog_Completed	map_office3	5	You survived Flathill and can now farm Power Cells there. Power the forklift and raise the blast door into Manufacturing.
5	MF	Manufacturing West	MF_ManufacturingOpen	map_MFStart	6	Manufacturing West is open. Somewhere in this sector is a tunnel to the surface - explore and find your way out.
6	MFBlacksmith	Manufacturing West	MF_MetBlacksmith	map_MFStart	6	You meet the Blacksmith (Varsha), who knows the sector: the Surface Tunnel is the main heavy-traffic route out.
7	MFMines	Manufacturing West	MFMines_Entered	map_MFStart	7	The Surface Tunnel is blocked. You descend into the mines beneath Manufacturing to find Frake, who may know another way.
8	MFFrake	Manufacturing West	MF_MetFrake	map_MFStart	8	You found Frake. The plan: get the Blacksmith's help forging parts to repair the sector's three electron pumps.
9	MFTrain	Manufacturing West	MF_OpenTrainStation	map_MFStart	9	The train station is open, connecting Manufacturing's far reaches while you gather pump materials.
10	MFPumpsFixed	Manufacturing West	MF_PumpsFixed	map_MFStart	9	All three electron pumps (yellow, green, red) are repaired. Time to activate the Synchrotron and overload it to blast an exit.
11	Pens	Cascade Laboratories	MF_ExitOpened	map_labs	10	The synchrotron overload opened the way out of Manufacturing. You emerge into Cascade Laboratories through the holding pens.
12	Labs	Cascade Laboratories	Labs_MiddleProgression	map_labs	11	Explore the Labs Sector for a way out; survivors suggest the Inner Wing containment blocks hold what you need.
13	Containment	Cascade Laboratories	Labs_Containment_Entered	map_labs	12	You're inside the Inner Wing containment blocks - deadly experiments, turrets, and the route toward the Control Center.
14	Helmholtz	Cascade Laboratories	Labs_Helmholtz_Opened	map_labs	13	The Helmholtz Wing is open, the path to the Control Center where the security system (and its turrets) can be reset.
15	Tarasque	Cascade Laboratories	LABS_TurretsDeactivated	map_labs	14	Via the Furniture Store anomaly you reached the Control Center and reset security - the turrets are off (and the Tarasque met).
16	Mycofields	Cascade Laboratories	LABS_AnteverseBFixed	map_labs	15	The Anteverse 2 portal is fixed: gather chemicals in the Mycofields' "Shroom" zone to make Antethermite for the Vacuum Chamber door.
17	PostLabs	Security Sector	LABS_OpenVacuumDoor	map_security1	16	The vacuum door is breached - you infiltrate the Security Sector, aiming for the Large Surface Elevator, one of the facility's most secure exits.
18	SecSurfaceElevator	Security Sector	Security_SurfaceElevatorEvent	map_security2a	17	The surface elevator crashes catastrophically. Stranded, you explore Canaan for ingredients and open the remaining gates to escape the sector.
19	EndSecurity	Hydroplant	Security_ExitOpened	map_dam1	18	The Security Sector exit is open; there's only one way forward - down into the Hydroplant.
20	ElectricalStation	Hydroplant	Dams_ReachedCentral	map_dam2	18	You reach the central dam. Survivors in the Electrical Station (Jonas) can help - reactivate the station, reboot the spillway computer, and open the flow controls.
21	Voussoir	Hydroplant	Voussoir_Entered	map_dam3b	19	You step through to Voussoir, the drowned cathedral anteverse reachable from the Hydroplant.
22	EndDam	Hydroplant	Dams_SpillwayOpen	Map_Dam4	20	The spillway is open. The only way out of the Hydroplant is wet: ride the water down toward the Reactors.
23	PowerServices	The Reactors	Plant_EnteredPlant	map_powerservices	21	You enter Power Services. A massive fungal bloom blocks the way to the Reactors - you need something to kill it.
24	AnteverseC	The Reactors	Plant_AnteC_Entered	map_anteversec	22	You enter Anteverse C (the Far Garden) to gather what's needed for Anti-Fungal Gelatin.
25	ReactorsEntry	The Reactors	Plant_ExitOpened	map_reactorsentry	23	The bloom is destroyed and the way into the Reactor Sector is open - you hope that was the right thing to do.
26	Reactors1Labs	The Reactors	Reactors_FirstContact	map_dflabs	24	First contact in the Deep Field labs: Dr. Cahn explains the Gatekeeper's exit waygate needs four reactors online. Activate Dusk Reactor and report back.

33	Botanical	Residence Sector	Res_EnteredBotanicals	map_botanical	33	You enter the Botanical Gardens, the overgrown heart of the Residence Sector's upper reaches.
34	DarkLens	Residence Sector	Residence_Wall	map_fracture2	34	Past the wall lies the Dark Lens. Collect its fragments, face The Fallow, and open the way out of the facility at last.
35	SouthIsland	Residence Sector	Residence_Fracture_Complete	map_southisland	35	The Fracture is behind you: you arrive at the South Island, whose altar can supposedly take you anywhere - Dr. Cahn and Thule have thoughts.
36	EndGame	Main Story Complete	EndBossDefeated	map_endgame	35	The Wayseeker is defeated. The end? Talk to Dr. Cahn, Janet, and the Sister of the Unlost. Main story complete.

Notes for the quest UI:

• Chapter card art lives at /Game/Textures/GUI/ServerBrowser/map_<name> - one per chapter (some shared), ideal thumbnails for a linear quest list.
• The in-game quest panel (Journal map page) shows only a short Quest_text/Quest_description pair - our richer per-chapter blurbs above are a superset, written from the wiki's objective texts.
• Region grouping for the UI: Office (0–4), Manufacturing West (5–10), Cascade Laboratories (11–16), Security (17–18), Hydroplant (19–22), The Reactors (23–28), The Praetorium (29), Residence (30–35), Complete (36). Portal-world chapters (Flathill, Voussoir, AnteverseC, Shadowgate, Fracture, SouthIsland) belong to the region whose DisplayText they carry.
• Triggers: writing the chapter's WorldFlag row name into the owning region's WorldFlags array is what the game itself keys on; StoryProgressionRow in WorldSave_MetaData.sav is the cached current row name.
