Open Items Register

This is the single register for open work, open design questions, unresolved documentation debt, and known code/design divergence pointers.

Rules:

• Every gap found by any pass gets logged here immediately, in the same pass that found it.
• Kind says what has to happen before a row can move.
• defect — something is wrong today and the fix is already known
• undecided — a decision has not been made; nobody can act until it is
• task — agreed work, not a correction
• Log undecided while designing, not while comparing documents. A reconciliation pass that records every unmade decision as a finding manufactures a backlog that can never empty, and buries the real defects among ordinary unfinished design. During a document comparison, log defect and task; log undecided only when the gap blocks something else, or when a specific audit was asked for.
• Nothing may exist only in a design document.
• Design documents describe the design. Open work lives here.
• The register is the only place open work lives; if it isn't here, it doesn't exist.
• IDs are stable. Never reuse or renumber an ID.
• ⚠️ When editing rows by script, anchor matches to the start of a line. An ID also appears inside the Blocked by column, so searching for | OI-041 | finds another row's blocker field before it finds the row itself. That has silently spliced two rows together twice.
• Prefix note. CI-001 to CI-053 in closed-items.md are the batch closed during the 2026-08-26 consolidation, before this register existed. They keep that prefix permanently. Every item closed since then keeps its OI- id when it moves, starting with OI-024. The two blocks are not renumbered into one scheme: CI- and OI- numbers overlap (CI-001 and OI-001 are unrelated items), so unifying them would mean assigning 53 new IDs, which is renumbering done to tidy up how the never-renumber rule was applied.
• When an item closes, move the row to docs/closed-items.md and add how it resolved. Never delete a row.

ID	Area	Kind	Item	Intent steer	Detail lives in	Blocked by	Priority	Raised
OI-001	code	task	Implement fluid as a production input path for buildings.	-	AGENTS.md -> Known Code/Design Divergences; 04_Factory -> Resources -> Fluids	-	DO FIRST	2026-08-26
OI-004	ports	task	Unblocked 2026-08-30; this is now the refactor itself. Plan and implement the coordinated port refactor that replaces IoConnector and PipeConnector. Sequencing constraint: the Building Detail Panel does not exist and is on the critical path. All ports default to DISABLED (OI-058) and port configuration lives in that panel, so merging without it produces a factory that cannot move anything; the panel must cover every port in both directions and also carry recipe selection (OI-320), since ports cannot be configured before the building knows what it makes. Port reconfiguration is an instant UI action, not a Genesis task (OI-259), so GenesisTask.Type shrinks by two and grows by none. Regression baseline exists as of OI-258: tests/unit/test_item_transport.gd covers the chain end to end and pins constraints C3, C4 and C5, and is designed to be re-run after the refactor. Split the passes: the item half is well-bounded (~400 changed lines across 11 files); the fluid half is now scopeable since OI-003 decided direct transfer (two touching fluid ports are a pair-equalisation pair with the pipe removed). C5 connector chaining is the one deliberate loss - test_connector_chaining_passes_items_between_adjacent_connectors should be deleted as part of the work, not quietly broken.	item half first; delete the C5 test knowingly	23_Port System Design -> Code Impact Summary; tests/unit/test_item_transport.gd; AGENTS.md -> Known Code/Design Divergences	-	DO FIRST	2026-08-25

OI-010	code	task	Move Chemical Gas onto the fluid path. Previously scoped as "retype the .tres to FLUID", which would not have fixed anything: nothing enforces the belt/pipe split via tier. Belts never check tier or any fluid flag; the separation is structural, with fluids moving through fluid_inventory / pop_fluid_output() and items through inventory / pop_output_item(). Chemical Gas rides belts because it has an item-shaped definition, not because its tier is 0. The real work is moving it to the fluid path, which is why it was always blocked behind OI-001. Under the new model it becomes chemical / GAS, and rides pipes because it is a gas rather than because a field says so.	gases travel as FLUID	06_Design Session Decision Log -> Resource Data Model; AGENTS.md -> Known Code/Design Divergences	OI-001; OI-276	HIGH	2026-08-26

SimulationManager._simulation_tick() ticks them at P3b/P3c (:174-182), then P3d calls PipeSystem.simulation_tick() which ticks the same objects again (PipeSystem.gd:139-142).

Bumping the constant will not reject old saves. This matters now because the port refactor renumbers GenesisTask.Type: removing PLACE_CONNECTOR (index 4) and PLACE_PIPE_CONNECTOR (index 6) shifts FETCH_MATERIALS 7->5 and DEPOSIT_MATERIALS 8->6, and the load match has no default arm, so an old save silently constructs the wrong task type and then errors on a missing key.

BuildingInstance.tick_output() (:166-171) is an uncalled no-op still sitting in the tick path's shape. src/entities/pipes/PipeConnector.gd is a 171-byte dead stub superseded by the buildings/ version, and is not listed in the refactor's deletion table.	-	BuildingInstance.gd:166,283; src/entities/pipes/PipeConnector.gd	-	NORMAL	2026-08-27

The tier enum conflates production depth (RAW/REFINED/COMPONENT/ADVANCED) with transport medium (FLUID), so a resource that is raw by origin and fluid by medium cannot be described correctly. Drop tier entirely. It is not serialised, it is read once as a fallback in FactoryStats whose primary path already derives category from the producing building, and that reader bypasses it for fluids with a begins_with("fld_") check. Production depth is derivable from the recipe graph. Transport is derived from phase, not stored - solids ride belts, liquids and gases ride pipes, as a rule in code rather than a field. 19 .tres files. Do this before the port refactor (OI-004): ports gating on phase is cleaner than ports gating on an enum about to be deleted.	four axes; ids stay as stable handles, nothing collapses	06_Design Session Decision Log -> Resource Data Model; ResourceDefinition.gd; FactoryStats.gd	-	DO FIRST	2026-08-28

A filled barrel is not a liquid in a different form - it is a steel container, an ordinary SOLID item that happens to hold liquid, so it rides belts for the same reason every other solid does. Barrelling needs no special machinery: coolant (LIQUID) + empty_barrel (SOLID) -> coolant_barrel (SOLID) and the reverse, with the relationship living in the recipe graph like every other production relationship.

This is prototype scaffolding, not a design gap: the tiers were documented ahead of the data.

Basic mode uses fixed flow rate." In code, PipeNetwork.simulation_tick() calls _propagate_fluid(pipe_system, true) for basic, but that function's _fixed_flow parameter is explicitly unused - its own comment says "kept for API compatibility... unused here" - so basic and standard move fluid identically at 40% of the difference, and basic differs only by skipping pressure propagation. Surfaced by a GUT test that had asserted the fixed-flow model since before 336270d and had been failing on main ever since (fixed under OI-258). Decide which is right: implement fixed flow for basic and give the parameter a job, or drop the claim from the document and delete the dead parameter.

OI-323	modules	defect	Two documents give the power module different names for the same mechanism. 24_Module System Design §2 and §4 call it a Power Pole that "distributes power over an area from the building roof", and 08_Research Tree Design Branch 8 follows that. 25_Power System Design §8 says it is "no longer a 'roof-mounted pole'" but "a range extender on the building's integrated transmitter, turning any building into a distribution relay without a dedicated pole", and 25_Power §4c.4 gives it a concrete +8 tiles. The mechanism agrees in both readings - the module makes a building act as a distribution point - so this is a naming and framing conflict rather than a design one, which is why it was not settled during the OI-246 audit. 24_Module is the stated authority for modules and its name was kept in the tree pending this. Decide which framing is canonical and make the other match; the roof-pole framing carries a spatial-upgrade rationale (§4, reclaimed ground) that the range-extender framing does not, and that rationale is worth keeping or consciously dropping.	one name, and keep the spatial rationale if it survives	24_Module System Design §2, §4; 25_Power System Design §8, §4c.4; 08_Research Tree Design Branch 8	-	NORMAL	2026-08-30
