Two findings from #269. A reference from a container into a placement
nested in it was dead from the start, and deleting an asset left
references to the objects it took along showing "(missing)".
- A reference is stored the way its holder shows the object. In a
container tab that is q~x for content of a nested placement q.
- referenceCandidates translates it when the container is placed: in
placement r, q~x becomes r~q/x. pathOfId and idOfPath in instance.ts
do the mapping, objectChoices offers the same spelling the other way.
The rule holds at any depth.
- Storing q/x as proposed in #285 was dropped. The container tab would
then have had to translate its own ids.
- No migration. All projects and snapshots hold three references, none
of them with ~ or /.
- Create container lets a reference to content of a member placement
follow it. It was left dead before.
- Paste lets such a reference point into the copy. It kept pointing at
the original before. Both go through the new renamedReference.
- Delete asset records what every holder shows before the cascade and
clears every reference to an object that is gone afterwards, with
dropReferencesToGone from #269. The row shows None, undo restores
the references (#286).
Tests:
- Gate: 198 files, 2882 tests (2873 + 9), exit 0
- Unit object-references: 26 passed (17 + 9)
- e2e 1-17,57: 566 checks passed, 57 has +57i and +57j
- Six unit counter-probes fail between 1 and 3 tests each
- The browser counter-probe fails 57i and 57j as described in the
issues
- e2e total 1609 is computed, not measured in a full run

An Object variable could only be set by a graph while the game runs.
A placed object always showed "(null)", although the other objects of
its scene are there to choose from and the runtime can already find
any object by its id. Now the placed object stores a reference to one
of them, and the running game turns it into the real object.
- Stored as {"$object": "<id>"}. The empty placeholder stays as it
was, so old projects load unchanged and empty still means "(null)".
- The row of an Object variable on a placed object is a dropdown with
None and every object of the scene, indented like the Hierarchy.
The same goes for Object fields in structs and Object items in
lists, also in the Variables and List tabs.
- The behavior asset keeps "(null)". An asset has no scene, so "Apply
to asset" is gone from Object rows.
- The runtime resolves the reference when the Variables or Properties
node reads it. A destroyed target reads as null, a missing one shows
"(missing)" in the row.
- Inside a container only objects of the same container are offered.
The reference keeps the template id, so every placement finds its
own copy.
- Deleting the target clears the reference in the same undo step.
Paste points references inside the pasted group at the copies and
leaves outside references alone. Create container and Unpack carry
references along with the new ids.
- A value a graph writes while running stays in the run. The scene
keeps the picked object, also in "Run in editor".
Found on the way:
- Setting an override coerced every object slot to empty, in plain
values, struct fields and list items. The shared objectPlace() now
keeps the reference.
Not done:
- No eyedropper to pick in the scene, the dropdown is enough for now.
- Deleting a template object in the container editor does not clean up
references in other scenes. They read as null there.
Tests:
- ./check.sh: 187 files, 2724 tests, CHECK EXIT 0
- e2e 1-9, 51, 57: ALL PASSED, 389 checks
- e2e 1, 57 on the final bundle: ALL PASSED, 17 checks
- 13 unit tests in object-references.test.ts, 5 checks in e2e 57
- Counter-checks: 8 unit breaks fail their tests, the browser break
without a pick list fails 57b-57d

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.

- applyCommands sit on ObjectEditCommand with a revert hook instead of
five copies of the same preamble and undo
- actionIf replaces six identical Reset/Apply menu blocks, addNameField
the three name rows, assetLink the two asset links
- requireStructuralObject replaces ten two-line preambles and drops the
duplicate holder lookup
- __gm.objectsOf had no caller; the SMB remnant in e2e.sh is gone
Proven: check.sh 797 tests, full e2e 633 checks, smokes 24/19/20 against
the same bundle.

Split GraphCanvas (1076 -> 831 lines) into EdgeLayer and graphMenus;
the port and marker menus were the same list and are now one function.
Value specs of the inspector and the list tab share valueSpecs.ts, and
the remaining copies (compound commands, type glyphs, typed asset
lookup, name rule, play/editor world setup, marquee) are merged.
Four copies had already drifted apart; merging them fixes:
- "Disconnect N links" in the port menu is one undo step, not N
- "+ Add collider" is hidden on a placed container instance, as in
the hierarchy menu, instead of always failing
- a bool property coerced from the text "false" becomes false
- a port command on an unknown node type reports instead of crashing
Comment-only edits leave the bundle byte-identical. README corrected in
35 places (step limit, jump-run clock, suite duration, 409 body, ...).

A scene now stores only the container object; its content is resolved from
the template on every read, with deviations kept as sparse instanceEdits on
the container object. This drops the propagation bookkeeping entirely --
templateSync.ts is gone and the three structural gaps (add, remove, reparent)
cannot diverge any more.
Values stay editable on an instance, structure does not; Unpack writes the
content into the scene, keeping ids. Play mode bakes containers into the
throwaway copy before entities are built. No migration: formatVersion is 2
and the seeders write the new format.

The Container tab reuses SceneViewport against any object holder, so a
container template is edited exactly like a scene. Right-click no longer
changes the selection, which previously made nesting impossible: opening
the menu on a container loaded it, and "Place in container" then targeted
itself.
Template edits (move, rename, override) now reach already-placed instances
per slot, through a shared templateSync used by both the apply path and the
plain object commands. Copies the user has touched keep their own value.

Remove comments that only restate the code, keeping the section banners
and the notes that carry a reason, a measured fact or an external
contract.
ButtonOptions.width claimed to be a fixed width but only set minWidth,
so the Graph and Texture pickers grew with the name they showed. It is
now what it promises, with a separate minWidth for the buttons that have
two forms. Narrow buttons shrink their padding, otherwise a 24px icon
button had 8px left for its glyph and truncate dropped it entirely.
__gm.labelsDropped() guards that class: the overflow guard only saw text
that was too wide, never a label truncated to nothing.

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.

- SceneObject.editorOffset (x/y): shifts only where an object is drawn in
the Scene tab, cascades to children, undo-able with a reset action.
Never written into container templates.
- On click without an owner now fires for any click inside the camera
frame instead of hit-testing the (editor-only) behavior symbol.
- seed-jumprun: coins are a "Coin" container (sprite + trigger), nested
containers are expanded recursively, Destroy targets the coin's parent,
and the clock uses a Ceil node instead of ToText.
