readSystemSoftware lists a PC's or notebook's installed applications with
the settings the model needs: server applications switched on and their
port, the generic client's target, DNS recursion, web server virtual
hosts, Gnutella's peer limit and the personal firewall (on by default,
unlike a router's). Defaults the file leaves out are measured in Java.
All 23 corpus files match Java.
Two examples install an application of their own (Accumulator,
Broadcast), compiled into projekt/anwendungen; it is left out with a
warning, as this reader cannot run Java classes. It must survive a save.

importProject turns a PC's or notebook's Java file tree into Swift's
virtual file system, as Swift's registerVirtualFileSystem does: images
by type or extension from Base64, text by type, unknown types as binary
data or text, unsafe names and collisions left out with a warning, and
the whole import rejected over the project quota. NSString.pathExtension
is measured in the oracle, which now writes every imported file system.
On the 13 files Swift reads completely every file matches, images
compared by hash. Intended: a host whose file has no file system stays
empty, as in Java, where Swift adds the demo files of a new device.
Pending the applications step, the comparison reads our /webserver as
Swift's /www and leaves out the e-mail and Gnutella state files.

The core gains Swift's virtual file system (paths, case-insensitive
lookup that keeps the spelling, quotas, atomic changes, the defaults of
a new device) and the string behaviour the ported code relies on without
saying so. Both are measured in the Swift oracle: 11 file system cases
(the three Swift tests among them) step by step, and trimming, lower
case, equality, ordering and Base64 case by case — whitespace and control
characters over all of Unicode.
Found by measuring:
- Swift trims NEL and ZERO WIDTH SPACE, not the BOM; JS trim() does the
opposite. The .fls import now trims with swiftTrim.
- lowercased() maps scalar by scalar: a word-final sigma stays σ.
- Foundation decodes "====" and "Y===" as empty data.
- Foundation on Linux counts 24,735 plane-14 scalars as control
characters, a table artefact; the port keeps Unicode Cc+Cf.

readSystemSoftware reads a host's file system: Java's tree of
DefaultMutableTreeNodes, directories named by their user object, files
as Datei (by setters or the three-argument constructor), rooted at
arbeitsVerzeichnis (up to 1.10) or root. All 23 corpus files match Java,
every file compared by name, type and the SHA-256 of its content.
Routers and home routers have files in Java too, but their constructor
makes them from templates (the start page of the firewall's web
interface); they are not in the file and not claimed here.

importProject carries the DHCP client switch and server settings (hosts
and home routers), a home router's port forwarding rows and a modem's
pairing into the model; the core gains the types, ported from Swift.
The Swift oracle writes them too, and they match on the 13 files Swift
reads completely. Configuration text is now trimmed throughout, as Swift
trims every value it reads (routes and firewall rules included).
Outside those files Swift switches every DHCP server of the Internet
examples off: their "aktiv" refers to a shared Boolean it cannot follow.

readSystemSoftware adds the DHCP client switch and server settings of
every IP stack, a home router's static NAT table (port forwarding) and a
modem's mode, port and address. All 23 corpus files match Java.
Static DHCP assignments follow setStaticAssignedAddresses: each entry is
split at Java whitespace (the same 25 characters as Character.isWhitespace,
measured over the BMP), and an entry without MAC and IP ends the list, as
Java throws there.

importProject carries the system software settings into the model the
core runs: switch SSID and learning time (an SSID Java would roll comes
from the node id, as in Swift), a host's wireless network, manual routes,
RIP and the firewall of every router and home router. The Swift oracle
writes these settings too; they match on the 13 files Swift reads
completely.
A router's default gateway — its first interface's, which Java routes to
(Weiterleitungstabelle.holeTabelle) — is imported into the router's
device configuration. Swift's model drops it; in internetwork_komplett
the way back from 141.99.5.10 depends on it. A test pings across three
routers in the core, with and without it.

readSystemSoftware adds to each node what the topology needs from its
system software: a switch's SSID and learning time, a host's wireless
SSID, a router's RIP switch, the manual routes and the firewall of a
router or home router. All 23 corpus files match Java.
- A router's firewall is one object its constructor hangs in two places;
the corpus writes it under the web server's "konfig" plug-in. The
places are merged.
- The decoder keeps entries a constructor made in a map, reached by
get(key) (installed applications), like the elements of a list.
- The Java oracle loads every file twice and writes values that differ
as null: what FILIUS rolls (MACs, a switch's SSID) without text search.

importProject builds what the simulation core runs from Java's view of a
file: nodes with kinds and ports, links between port ids, device and
interface IP configurations, documentation items with Swift's derived
ids. The core gains the model types it needs (node, link, graph,
documentation item), ported from filius-ipad.
Checked against the Swift import, which the Swift oracle now writes in
full (corpus.swift.json, "state"), on the 13 files Swift reads
completely. Two differences are intended and named in the test:
- a device the file leaves unnamed has Java's default name
("Switch / WLAN"), not Swift's;
- multicast_server.fls: useIPAsName refers to a shared Boolean that
Swift cannot follow; Java shows the IP address, and so do we.
All 23 files import with as many devices and cables as Java has, and an
imported example pings across its router in the core.
Port counts of switches and routers follow Java's lists instead of
Swift's guess from references.

readTopology maps the decoded JavaBeans graph to devices, cables and
documentation items the way SzenarioVerwaltung.netzwerkLaden does: the
kind from the Java class (the palette label is not file data), devices
without bounds at 0,0, interface values through Java's setters. All 23
corpus files match Java field by field.
Found on the way:
- listItems mixed a constructor's elements with added ones; a router's
second interface was lost. Lists now replay add/set in order after the
elements the constructor made.
- The first 0 of a file may be SwingConstants.CENTER; measured like the
getter defaults.
- IP.ipCheck (javaIp.ts) measured on 46 cases: empty tokens skipped,
signs, leading zeros and BMP digits of any script accepted.
- The Java oracle took lower-case MACs in a file for random ones (8
interfaces); it now compares case-insensitively and reports the host
name flags.

A generic interpreter for the .fls configuration: objects, properties,
calls, indexes, static fields and factories, Field.set, and id/idref
anywhere — including getter results, answered from the measured Java
defaults or reported as unresolved. All 23 corpus files: class and
position of every node as Java reads them, also where Swift loses nodes.

XMLEncoder shares equal Integer objects, so a node's x coordinate can be
written as a reference to the result of JSidebarButton.getIconTextGap().
GetterDefaults constructs the classes like XMLDecoder does and records
what the getters return (packages/fls/src/javaDefaults.json).

41 path pairs replayed in the Swift core decide which spellings name
the same file. Two corrections: full Unicode case folding (ß, ligatures,
final sigma, micro, long s) instead of toLowerCase, and width folding of
the whole Halfwidth and Fullwidth Forms block. Swift treats composed and
decomposed spellings as one dictionary key; here the writer refuses both.

Reader and writer ported from filius-ipad with the same path policy,
limits and error codes; DEFLATE via fflate, cut at the declared size
like Apple Compression. 54 tests: the Swift archive rejection tests,
DEFLATE edge cases, and all 23 corpus files cross-checked against
fflate.unzipSync and round-tripped.

tools/java-oracle builds FILIUS at 6640354 and loads every .fls through
its own private loader under Xvfb. All 23 files load with every node
positioned and every cable resolved (Swift: 20 of 25 nodes in the
Internet example). MAC addresses FILIUS generates are left out, so two
runs are byte-identical.

The oracle gains a corpus mode; run.sh now stops on a failed build
instead of running a stale binary. Swift reads all 23 files but drops
Java gateways labelled 'Heimrouter' and nodes whose bounds are written
through XMLEncoder back-references.

tools/swift-oracle builds the unchanged Swift runtime (pinned 3b5ded0)
in Docker and replays JSON scenarios; the TypeScript engine must produce
the same trace events, results and end state. Five scenarios, 884
events, identical.

First slice of the TypeScript port of the filius-ipad runtime engine,
with 29 tests ported from the Swift suite. Parts not ported yet throw
NotPortedError instead of guessing.
