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 state machine is an asset whose graph holds one `State` node per state
(no ports, name as title), edited in a new "State machine" tab that reuses
the graph canvas: right-click places "State n", snap toggle shared with the
Behavior tab via SnapToggle. `statemachine` is a value kind like texture
(port, literal node, variable, struct field, tagged list item).
Behaviors use it through `State branch` (one exec output per state) and
`Set state` (one exec input per state; the interpreter now hands `run` the
entry port). States live per behavior instance in NodeContext.states, with
no initial state. Ports derive from the inline picker or a wired
`State machine` literal; BehaviorLookup became GraphLookup with
behavior(id) and machine(id).
The Graph tab is labelled "Behavior" (key unchanged). Unit tests
(state-machine, kinds, catalog, ports), e2e step 26 and README added.

Collapsed, the node reads "Set 2 variables", "Get width" or "No properties";
expanded it is always "Variables" / "Properties". The Properties node shows
its object type (and behavior) as a line under the title instead.

Get/Set property, Get/Set properties, Set enabled and Set text are gone.
A single Properties node takes a fixed "object" input; every chosen
property is an output that reads the current value, and one switched to
Set is also an input written when the flow arrives. Exec pins only exist
while at least one entry writes.
The node carries a type (Sprite, Text, Collider, Camera, Container,
Behavior, Any) that decides what "+ Property" offers: the fields of that
type, the variables of the chosen behavior, or for Any a kind to pick
and a name to type. Each port takes the default and field of its type,
so a Camera width starts at 640. Switching the type keeps the ports and
marks those the new type lacks. At runtime the type is only an editor
aid; the node writes to whatever object it gets.
Old project files are converted on load. The type is inferred from the
keys: the first object type that has them all, else the one behavior
that declares them all, else Any. enabled belongs to every object, so a
converted Set enabled lands on Any.
The jump-run and tetris seeders use Properties throughout; draw-piece
switches its cell on in the same node that sets the colour.

A single node now lists any number of variables. Every entry is an output
that reads the current value whenever it is pulled; an entry switched to
Set is also an input and is written when the flow arrives. Exec pins only
exist while at least one entry writes, and all inputs are read before any
write, so one node can swap two variables.
Get/Set variable, Get/Set variables and Variable are gone. Old project
files are converted on load: each old node becomes a Variables node with
the same variables, edges and typed values.
A written port without a typed value now shows the zero of its kind on
the node body, matching what the inspector shows and what the run writes.

Get properties / Set properties work like their variable counterparts:
one port per chosen property, an unconnected input writes its inline
value. A port chosen from the built-in list keeps that property's field
and default (height starts at 100, color is a colour field). "object" is
reserved for the fixed input, checked by the command and on load.
The property picker names the owning type ("Sprite width"), and text
fields can now carry a suggestion list; Get/Set property use it.
Double-clicking a call node shows the path of opened behaviors under the
graph header. Clicking an entry jumps back and trims the path; choosing
a behavior any other way hides it. Reopening a behavior already on the
path steps back to it instead of repeating it. The bar shows before the
graph switches, otherwise it clips the graph that was just fitted.
The "Add node..." header button is gone; nodes come from the context menu.
