CI-038	logistics	Decide what happens when a filtered Router output backs up.	priority is overflow	20_Belt Logistics - The Router -> Priority IS the overflow mechanic	-	NORMAL	2026-08-25	Resolved. Backed-up output loses its turn and items waterfall to the next priority.
CI-039	logistics	Decide whether the Incinerator recovers anything.	capped below embodied energy	20_Belt Logistics - The Router -> The deliberate way out	-	NORMAL	2026-08-25	Resolved. It recovers heat as power, never profitably.
CI-040	trains	Decide whether trains require Fuel Cells or abstract locomotive power.	-	22_Trains & Rail -> Related Existing Question	-	NORMAL	2026-08-25	Resolved. Neither; fuel type distinguishes locomotive types.

CI-050	world	Decide starting planet naming.	fixed lore name	05_World Generation & Planet Types -> Open Questions	-	NORMAL	2026-02-26	Resolved. Fixed lore name, not procedural; exact name remains in World Bible scope.
CI-051	outpost	Decide whether Outpost co-op uses both Genesis bots or one.	one Genesis	06_Outpost/01_Outpost Mode Overview -> Open Questions	-	NORMAL	2026-03-13	Resolved. One Genesis.
CI-052	outpost	Decide whether enemies attack Genesis.	aliens yes, external drones no, internal drones yes	06_Outpost/01_Outpost Mode Overview -> Open Questions	-	NORMAL	2026-03-13	Resolved. Aliens and internal drones attack Genesis; external drones do not.
CI-053	outpost	Decide physical presence versus remote management panel for Commander role.	physical presence only	06_Outpost/01_Outpost Mode Overview -> Open Questions	-	NORMAL	2026-03-13	Resolved. Physical presence only.
OI-024	research	Rewrite Research Tree Branch 8 for Module Technology, fixed slots, and no stacking.	-	08_Research Tree Design -> Branch 8; 24_Module System Design -> Research node names	-	HIGH	2026-08-25
OI-016	pollution	Decide whether waste systems get their own research branch or join an existing branch.	-	26_Pollution, Waste & Organic Systems Design -> Waste Handling - Three Choices	OI-242	HIGH	2026-08-26	Decided 2026-08-27. Branch 9, Environmental - waste treatment, remediation and farming together. Building count was the weakest argument; discoverability of an endgame path was the strongest. Restoration is canonical as one of three endgame routes (Canonical section 12), and a route whose toolset is scattered across branches named for other things is not a route. The three systems are coupled by real dependencies, not theme: farms feed Soil Remediation, farms feed the Biomass Burner, recycled organic waste feeds farms as fertiliser. It also has a genuine Tier 1 anchor in the Biomass Burner, so the branch is not a locked region the player can see but not enter. Implementation is OI-248, blocked on OI-247.

OI-269	farming	task	Rewrite Pollution section 7: three crops become two families.	-	26_Pollution, Waste & Organic Systems Design -> Organic Farming	-	HIGH	2026-08-27
OI-247	design	defect	25_Power System Design and 26_Pollution, Waste & Organic Systems Design both assert an organic production chain that does not exist. No resources, no buildings, no recipes. Pollution section 7 lists fast-growth timber, algae and bio-polymer crops as farm outputs; none is defined (raw_wood appears in zero files, algae and biofuel in none). No farm building exists anywhere in the vault - only building_biomass_harvester, which extracts wild biomass, a different thing from cultivated crops. Consequences today: the Biomass Burner is a generator with undefined fuel (25_Power System Design section 5.1 gives it "Wood (solid belt)"), and Soil Remediation consumes an organic input nothing produces. This is the same "already specced" failure recorded against Geothermal Tap and Core Power Station - a document asserting something exists is what stops anyone checking. Needs a design pass that invents the chain, not a reconciliation pass; wants a conversation rather than a prompt.	-	26_Pollution, Waste & Organic Systems Design -> Organic Farming; 25_Power System Design -> Source Table; 04_Factory -> Power Buildings	-	DO FIRST	2026-08-27
OI-062	logistics	undecided	Decide whether a Fluid Router exists or pipes junction implicitly.	-	20_Belt Logistics - The Router -> What Stays Separate	OI-004	NORMAL	2026-08-25
OI-271	data	task	Give Chemical Gas a phase, in three steps that must move together. A Router is configured ITEM / LIQUID / GAS and a gas Router cannot route liquid, but nothing in the code says which fluids are gases. (1) Add enum Phase { LIQUID, GAS } and @export var phase to FluidDefinition — not a new ResourceTier value, which would turn every tier == FLUID check into a two-way test, contradict Canonical section 3, and renumber an enum serialised as a raw int into .tres. (2) Create data/fluids/raw_chemical_gas.tres as a FluidDefinition and set phase = GAS; it does not exist today, so Chemical Gas has no viscosity, density or temperatures and nowhere to put a phase. (3) Retype data/resources/raw_chemical_gas.tres to tier = 4 (OI-010). Any one alone leaves an inconsistent resource.	enum on FluidDefinition, never a new tier	06_Design Session Decision Log -> Transport & Logistics; FluidDefinition.gd; ResourceDefinition.gd	OI-010	HIGH	2026-08-27
OI-131	logistics	undecided	Design drones/delivery bots beyond the current four bullets. Settled 2026-08-27: fluid only via barrels (OI-272) or a fluid-carrier variant; battery-limited with a recharge cycle; drones draw power by hooking onto power poles, giving the distribution tier a second job; drones cannot fly underground and change level through a vertical shaft, so underground logistics stays belts, pipes and rail. Still undesigned: payload, range, speed, Drone Port behaviour, routing, fleet rules, and whether power cost is per-trip or port-side.	Drone Port, routes, payload, charging	06_Design Session Decision Log -> Transport & Logistics	-	DEFERRED	2026-08-25
OI-312	docs	task	State the lossy-loop guard rail once, as a principle, and reference it from each system. It now appears four times independently: Incinerator heat recovery, the flue capture ceiling, nuclear reprocessing, and box recycling. The principle is that a loop which closes completely removes the decision it was meant to create. Four occurrences is a pattern, and restating it per system invites one of them being written without it. Natural home is 00_Canonical Design Facts.	one statement, referenced from each system	06_Design Session Decision Log -> Cache Boxes	-	HIGH	2026-08-29
OI-275	logistics	task	Write a Transport & Logistics design document once the carrier discussion completes. Decisions currently live only in the decision log: belts as queues versus pipes as pools, the Router's three configurations, drone barrels/charging/underground exclusion, and quantum travel's scope. Carriers still to cover when the session resumes.	-	06_Design Session Decision Log -> Transport & Logistics	-	HIGH	2026-08-27
OI-041	tooling	undecided	Decide the doc naming rule and make npm run check:docs match it. Now reports 21 findings, and at least two are false positives: open-items.md and closed-items.md are flagged as root-level strays, but they live at docs/ root deliberately and AGENTS.md points at that exact path. Of the 18 NN_ prefix findings, 10 are files cited by exact path in the 04_Factory Design Document Index, so renaming them would break the index. The likely answer remains narrowing the check, not renaming the docs. Genuine strays: ROADMAP.md and ROADMAP-COMPLETED.md.	narrow the check, do not rename	AGENTS.md -> Design Document Index	-	HIGH	2026-08-26

OI-013	docs	defect	Replace the generic Shaft model with Item Lift, Fluid Riser and Power Conduit in the remaining documents. 06_Vertical Layers is done (2026-08-27); 01_Master GDD, 08_Research Tree Design, 03_Procedural Generation Reference and 06_Design Session Decision Log still reference the generic Shaft.

OI-259	ports	undecided	No named mechanism for a player reconfiguring a port. 23_Port System Design section 9 removes PLACE_CONNECTOR and PLACE_PIPE_CONNECTOR and says ports come into existence with their building, but never says how a player changes a port from DISABLED to OUTPUT, or sets a filter. Either it is an instant UI action - which collides with the AGENTS.md rule that all placement is queued as a Genesis task, never instant - or it is a new task type such as CONFIGURE_PORT. This decides whether GenesisTask.Type shrinks by two or shrinks by two and grows by one, so it blocks the refactor.	-	23_Port System Design -> Genesis Task Types; GenesisTask.gd:11-21	-	HIGH	2026-08-27
OI-258	testing	task	Write end-to-end transport scenarios BEFORE the port refactor, against the current system. There is no GUT test and no ScenarioTestRunner scenario anywhere that exercises producer -> connector -> belt -> connector -> consumer. The three existing scenarios are all Genesis fetch/carry/build. The refactor replaces the item-transport mechanism with zero regression coverage on the behaviour being replaced, so scenarios must be written first to be runnable before and after.	write against the current system first	ScenarioTestRunner.gd:93-105; AGENTS.md -> Testing Scope	-	DO FIRST	2026-08-27
OI-320	ui	task	Recipe selection is not designed anywhere. accepted_recipe_ids is multi-valued in shipping data - Assembly Machine and Advanced Assembly carry three recipes each, Press Machine and Advanced Press two - but no document says how a player picks one. Nothing in 04_Factory or 09_UI-UX Design Document covers it. It is a prerequisite, not a nicety: 23_Port System Design §5.1b makes recipe selection step 2 of three, and §5.1c gates inbound port auto-enable on it, so a building with no recipe accepts nothing. Needs: where the choice lives (Building Detail Panel, beside port config), whether a single-recipe building shows the control at all, how extraction buildings present in the same panel, and what a recipe change does - to a running job, to buffered inputs, to auto-enabled ports (they follow the new recipe, their filter being empty) and to explicitly filtered ports whose filter the new recipe cannot use, which should be surfaced rather than silently cleared since the player set them deliberately.	panel owns recipe and ports together; never silently clear a player's filter	23_Port System Design -> §5.1b, §5.1c; 04_Factory -> Recipes; BuildingDefinition.gd	-	HIGH	2026-08-30

OI-242	research	defect	The research tree was never updated for any of the design work, and may describe a system that no longer exists. Not four separate gaps - one fact with four consequences (OI-243, OI-006/OI-016, OI-244, OI-245). Scoped individually they look like four small gaps; scoped together, research is the least reconciled system in the vault. Decide whether the tree is amended in place or rebuilt against current design.	-	08_Research Tree Design; 25_Power System Design -> The Three Tiers; 26_Pollution, Waste & Organic Systems Design -> Waste Handling - Three Choices	-	DO FIRST	2026-08-27

OI-243	research	defect	04_Factory and 08_Research Tree Design describe two different research trees under the same name. Nine of ten node names taken from 04_Factory appear nowhere in 08: Basic Logistics, Ore Processing, Basic Power, Advanced Logistics, Fluid Handling, Filter Logistics, Power Management, Rail Transport, Module Technology. Only Chemical Processing appears in both. Every research reference in the vault is therefore ambiguous about which tree it points at, including the Module Technology nodes written during the 04_Factory pass. Fix: 04_Factory's tree becomes a pointer, and the nine orphan names get audited - real design in 08 under different names, or genuinely absent. Run as its own pass once decided.	08 is the authority: it is the dedicated document, and 04_Factory calls its own version a summary	04_Factory -> Research System; 08_Research Tree Design -> Branch Overview	-	DO FIRST	2026-08-27

OI-244	research	defect	Transmission has no research nodes. Canonical section 8 has Generation -> Transmission -> Distribution. Branch 2 unlocks Power Conduit and Power Pylon under Power Grid Expansion, but there are no transformer nodes, no transmission lines and no voltage tiers - and transmission is the entire research path in 25_Power System Design section 3.2. The tree has no way to reach it. Distribution correctly needs nothing, since poles are baseline. Adding nodes means inventing RP costs.	-	25_Power System Design -> The Three Tiers; 08_Research Tree Design -> Branch 2	-	HIGH	2026-08-27
OI-245	research	defect	Biomass Burner, Wind Turbine and Nuclear Reactor have no research nodes. Branch 2 covers Fuel, Solar, Core Power and Geothermal only. All three are specified in 25_Power System Design section 5.1 and were added to 04_Factory in the ten-buildings pass. Adding nodes means inventing RP costs.	-	25_Power System Design -> Source Table; 08_Research Tree Design -> Branch 2	-	HIGH	2026-08-27
OI-246	research	task	Audit the remaining 08_Research Tree Design branches (1, 3, 4, 5, 6, 7) against current design. Branch 8 and Branch 2 both proved stale, so the others should not be assumed current.	-	08_Research Tree Design	-	NORMAL	2026-08-27
OI-248	research	task	Create Branch 9, Environmental - waste treatment, remediation and farming. Decision made (see closed OI-016); this is the implementation. Scope it as one pass that defines the organic chain and its research together, because nodes for buildings and resources that do not exist would just move the hole. Covers the five environmental buildings, the farm chain, and Restoration as a visible endgame route.

OI-322	research	task	Two node families are referenced by other documents but exist in no tree. Power Management gates the Power Priority System (04_Factory -> Power Priority System), and Bot Programming I/II gate the Construction Bot Bay and Genesis automation (01_Master GDD, and three places in 04_Factory). Both were defined only in the tier-gated 04_Factory listing deleted under OI-242, and because that listing contradicted the tree's structure they were never really in the tree at all - the fork made it look as though they were. This is the same class of gap as OI-244 and OI-245, and should be done with them rather than separately, since all three mean adding nodes and inventing RP costs in one balancing pass. Power Management belongs in Branch 2, Bot Programming in Branch 7 (Genesis Abilities) or Branch 1. Do not delete the four references - they state real design intent; it is the nodes that are missing, not the claims that are wrong.	add the nodes, keep the references	08_Research Tree Design -> §0.2; 04_Factory -> Power Priority System; 01_Master GDD	-	HIGH	2026-08-30
