Get world position now covers the world coordinates. Two nodes that
both offer world x and y made it unclear which one to take. No project
uses the world outputs of Get position any more.
- Get position drops its world x and world y outputs and its
description points to Get world position.
- Old snapshots with edges on those outputs still load. The edges hang
on ghost ports and the node warns about them.
- The unit tests in hierarchy and raycast and the graphs in e2e 43 use
Get world position where they read the world coordinates.
Tests:
- node-catalog, hierarchy, raycast: 3 files, 417 tests, all green
- e2e 43 on melektaus-atx: ALL PASSED, 17 checks

Recurring cleanup round over the code since round 7 (bc688f3). The
issue now also asks to fix bugs and small inconsistencies found on the
way, so unlike the rounds before, this one changes behaviour in a few
places. Duplicated code in api went from 23 clones with 228 lines to
none (jscpd, at least 50 tokens). In src it stays at 22 clones with
271 lines, the same before and after.
Bugs:
- nginx served project and snapshot files as they were, so anyone who
knew a project id could read it without signing in. Every file the
API writes now goes through AtomicFile (temp file, mode, rename).
Projects, snapshots, releases, accounts and sessions are 0640, and
nginx answers 403 for them.
- Any signed-in account could delete a shared image, font or sound,
which projects of other accounts may wear. Deleting one is now for
administrators only. The editor never deleted a file, so the
client's delete is gone.
- Two saves of one project could run at once. The lock file was
removed after each save, so a waiting save and the next one locked
different files. The lock file now stays, and deleting a project
takes the lock as well.
- Bytes that are no picture got a 500 instead of a 422, because the
error handler also threw for warnings silenced with @.
- A session file was rewritten in place. A request reading it at that
moment found it empty and was signed out. It is replaced atomically.
- Delete did nothing for a shape picked in the vector art list. Delete
now goes through removeSelection, one case per kind of selection,
and a kind without a case fails the type check.
Inconsistencies:
- Escape on a question does what its Cancel does. Cancel on "Delete
project?" and "Restore snapshot?" leads back to the picker or the
list like the other questions did, and so does deleting a project.
- Editor texts use American spelling throughout, like the port names:
48 British spellings in 45 lines (colour, centre, initialised).
- objectName and groupName replace eleven copies of "own name, else
the asset's" and three of "Group". One copy fell back to the object
id instead of "?".
Duplicates, dead code, comments:
- routeFiles serves images, fonts and sounds instead of three copies.
HashedFileStore holds what the three stores shared: keeping a file
under its hash with its name, listing and deleting. The stores keep
only which bytes they take and what a record says.
- AtomicFile replaces nine copies of temp file plus rename.
- removeShapes is the one way the canvas, the inspector button and
Delete take shapes out.
- GraphInterpreter.fire was called by tests only. The 54 calls use a
helper in tests/helpers.ts now.
- FileStore.delete, HttpFileStore.delete and the PluginApi type were
unused. A doc comment in actions.ts sat above the wrong function.
Checked and left as is:
- solidCells is used by tests only. It is the per-cell view before the
merge into rectangles, the one place the largest-scale rule shows.
- An undo checker ran all 124 commands of the unit tests and compared
the project before and after undo. The only differences are empty
ports, groups and notes lists where there were none, which the file
format drops anyway.
Docs:
- README: the check sum.
- Wiki, own commit: API (admin-only deletes, 422, file modes, lock
file), Home (the "Not yet" list named three things that exist),
Concepts, Keyboard, Vector art, Architecture and Development, and
the 38 characters Gitea flagged as ambiguous on eight pages.
- .gitignore: the lock files, and pasted-*.png in any folder, which
keeps the screenshot archive out.
Tests:
- ./check.sh: 195 files, 2817 tests, exit 0 (+2 for the name helpers).
- PHP: accounts 52 in the web container and 53 in the CI image with
the race test (+2), snapshots 15 (+1), releases 20.
- Full e2e run: ALL PASSED, 1586 checks (+6 in 12, 47, 49 and 50).
- Smokes jumprun, tetris, actor: 24, 19 and 21 checks. The example
project files were restored byte for byte afterwards.
- The file stores of HEAD and of this commit give byte-identical
output for the live folders and for store, list and delete in a
throwaway folder.
- Counter-checks, all fail as expected: a 500 for bad bytes fails 12,
no admin check fails 49, removing the lock file again loses saves
in 3 of 3 runs (151 to 170 of 321), Delete ignoring shapes fails 47,
Escape that only closes fails 50, and dropping the shape case fails
the type check (TS2366).

A scene with a hundred crates fills the hierarchy with a hundred rows.
Groups bundle top-level objects under one folder row that folds away.
They exist for the editor only. Parenting, positions and the game do
not see them.
- Model: a scene or container template holds a list of groups, an
object may carry a groupId. Old projects load unchanged. Loading
drops empty groups and members that are no longer top level.
- Only top-level objects can join a group. Parenting a member takes it
out of the group, and Undo puts it back. There are no groups in
groups.
- Order: treeOrder lists the members together, where the first one
stands. The same order decides drawing at equal z, in the editor and
in the game, so the hierarchy and the picture cannot disagree. The
stored object list stays untouched when grouping.
- Hierarchy: a group row shows a folder icon, the name and the member
count. Clicking it selects all members and keeps it folded. Selecting
a single member elsewhere unfolds it. Folding lasts for the session.
- Create with "Group..." in the object menu. A name dialog asks first,
so creating is one Undo step and Cancel creates nothing.
- The group menu has Select members, Rename... and Ungroup. The object
menu adds "Remove from group".
- Drag and drop: onto the group row appends, into a gap between members
inserts there, next to a row outside leaves the group. Dragging the
group row moves all members as a block. The drop rules live in
hierarchyDrop.ts as a pure function.
- Copy and paste keeps a top-level copy in the group of its original.
A container built from group members takes their place in the group.
- Clicking an object that is already selected together with others now
keeps only that object selected. ListView narrows the selection on
release, so a drag starting on such a row keeps the selection.
Not checked in the browser: groups in the container tab, "Remove from
group", Ctrl-click on a group row and a drag out of a multi-selection.
The code path covers them.
Tests:
- check.sh: 177 files, 2552 tests, CHECK EXIT 0
- e2e 1, 51, 52: ALL PASSED, 31 checks (new module 52)
- 19 new unit tests in object-groups.test.ts and hierarchy-drop.test.ts
- 9 counter-probes, all fail as expected (7 unit, 2 in the browser)

Four new rows on sprite, text, collider and container (block TRANSFORM):
scale, rotation in degrees clockwise, mirrorX, mirrorY. As properties they
get override/reset/apply, loading of old projects, write-back after play and
the Properties node for free; camera and behavior have none.
The hierarchy composes T*R*S per level (composeAlongChain replaces
sumAlongChain), so children rotate and scale with their parent. Reparenting
and grouping keep the look (carriedTransform). Drawing goes through
placeNode, the gizmo is a polygon, cull and objectRect use the AABB, drags
are computed in the parent's system.
Colliders are oriented boxes: SAT for box/box, box-circle in the box frame;
exitDistance replaces axisSeparation/axisCorrection, moveAndSlide moves along
the object's own axes.

- `Texture` and `Color` can be picked as a variable kind, a struct field
kind and a declared port kind; a new `Texture` node hands a picture id
into the graph. Declared, a texture is its bare id – the `$texture` tag
stays a list-only thing.
- The `String` node is labelled "Text" like its kind; the type id stays.
- Whole-number inputs (`Item at`, `Set item`, `Sub list`, `Fill`,
`Repeat`, `Substring`, `To text`) show no decimals (`int()` in shared.ts).
- All server projects are reseeded, so `legacyNodes.ts`,
`migrateDeclaredLists` and the `ownerId` fallback go, with their tests.
- Note `reseed-because-of-list` moved to done/; new note `refactor-types`.

A reference search over every export and method in src/ found code that
only tests still called, or that was never called at all:
- RemoveSceneObjectCommand: the product only removes through the
multi-object command; the tests now use that one too.
- NodeRegistry.requireNodeDef: a second function of the same name in
commands/require.ts raises a CommandError instead of throwing, and is
the one the product uses. The twin invited the wrong import.
- isTextureAsset, listContainers, AssetTabEditor.show,
FocusManager.destroy, KeyboardBridge.selectAll and the getters
ColorField.value, ListView.selected, NumberField.number.
Also: Theme.controlActive now matches the resting control colour, and a
new note asks what editing the graph during play would take.

The aspect button now carries two offers, so it becomes a menu: fit one
side to the texture ratio, or set both sides to the exact pixel size as a
single undo step.
Dropping a row on the outer quarter of another row inserts it into that
gap instead of parenting into it, reordering among the siblings there.
Order is the stored order, so ReorderObjectCommand is a splice; equal z
falls back to tree order, which makes this the way to draw one object in
front of another. Rejected on container content like the other structural
edits.

Tooling:
- Prettier as the single formatting authority (110 columns, single quotes,
measured against the existing style); Markdown excluded because table-cell
padding turns the README glossary into 1000-character lines.
- Type-aware ESLint ending in eslint-config-prettier, so a rule always means
"this is a bug", never "this looks different".
- .editorconfig and an `npm run check` that runs typecheck, lint, format and
tests in one go.
Findings fixed on the first run: three more duplicate imports, four
String(unknown) calls (parameter types narrowed instead of casts), two dead
initialisers, two redundant casts, a console.log for a real error. Two
warnings were false here and are disabled with a reason in place.
Tests 132 -> 269:
- node-catalog.test.ts covers every node with a run(), with a guard that fails
when a new node has no row.
- behavior-events.test.ts covers the ten event nodes through a running World,
checking timing rather than existence.
- Input's state machine (press/release/releaseAll) is reachable without DOM
events now; the DOM handlers are thin adapters.
Compare fell back to == without a configured operator although the schema
default is <; aligned.

- Inspector rows compute their reset/apply entries through providers, so an
entry that would not change anything is dropped; a single remaining entry
renders as a direct button instead of a menu, none removes it entirely.
- Bold and buttons now follow the same rule (deviatesFromAsset /
deviatesFromTemplate in core/properties/resolve.ts).
- Hierarchy panel is a collapsible tree: chevrons, arrow keys, double click,
expand/collapse all. Everything starts collapsed; selecting an object
expands its ancestors and scrolls it into view.

Engine additions that the example game needed:
- `enabled` as a shared property of every placeable asset (default on, an
override on the scene object). A switched-off object is not drawn, does not
collide and its behavior does not run - and neither does anything parented
below it. Disabled objects are now hidden in the scene view as well, so the
editor shows what the game shows; they stay in the hierarchy panel, which is
where they are selected and switched back on.
- Asset type `text` (text, fontSize, color, align), rendered in scene and game.
- Pointer input in the game view: `On click`, `Mouse position`, `Mouse button`,
`Is hovered`, hit-tested against colliders, else sprite/text footprints.
- New nodes: Set/Is enabled, Set text, Is asset, Name of, Equals, To text,
Join text, Floor/Ceil/Round, Modulo, Random, Time, Restart game.
Tooling: shared CDP harness (tools/harness.mjs), central project registry with
a guard that keeps destructive scripts off the playground (tools/projects.mjs),
plus smoke suites for the demo scene and the jump-and-run game.
