frame.create's text and text.insert kept CR and CR LF as characters, so text
written with InDesign's, classic Mac or Windows line ends ("One\rTwo") became
a single paragraph, and paragraph formatting (spaceAfter) never applied
between the parts. They now become \n, the paragraph separator, as edit.paste
and text import already did.

anchor and focus are byte offsets into the story text, as find.find reports
them, but the params doc said only {story, anchor, focus}. A script that
counts characters (Python's len()) selects too little after the first
accented letter: with "Matemática Básica" and focus 17, type.char left the
last two letters out.

Use the document model boundary helper for explicit selections and retained selections after story replacement. Cover editing and caret movement through the command API.

Session::execute runs each command inside catch_unwind: a panic that escapes
(any edit, import or export, from the UI, CLI, MCP or control channel)
becomes EngineError::Internal, the document and selection are restored to
before the command, and crash recovery is saved when enabled. The first
Session installs a panic hook that logs the message and location.

Commands return errors instead of expect()/unreachable!() (book, library,
undo/redo, paste, find/replace, Pathfinder, tables, QR, select, swatches,
anchors, articles, transform again, XML import). The sample document builder
propagates errors. Commands that add a key to their parameters no longer
panic when a caller (control channel, MCP, script) passes an array or a
string, and corrupt crash-recovery metadata is ignored. engine, mcp and
tools now deny unwrap/expect/panic/unimplemented/todo/unreachable.

The active layer lives on DocState, outside the undo snapshots, and
nothing re-checked it when the document's layers changed. After New
Layer → Undo (or Delete Layer / Delete Unused Layers / Merge Layers on
the active layer) it kept pointing at a layer that no longer exists, and
every object created next (frames, lines, placed images, pasted items)
was put on that phantom layer: not drawn on the canvas, missing from PDF
export, ItemLayer referencing an undefined layer in IDML, and preflight
reported nothing.
After each command, if the active layer is gone, make the top layer
active (as on opening a document).
Test: active_layer_survives_undoing_new_layer.

file.serialize returned {json: String::from_utf8_lossy(to_bytes(doc))},
but since M6.1 the native format is a zip (deflated document.json + raw
assets), not JSON text. from_utf8_lossy turns every invalid UTF-8
sequence into U+FFFD, so the result is not the file: on the web, File ›
Save downloads exactly those bytes (download_document), and the
downloaded .designcraft can't be opened again ("invalid Zip archive").
Agents calling file.serialize got the same unusable string.
Return {base64, bytes} like the other byte-producing commands
(file.exportIdml, file.exportPdf, snippet.export) and decode it in
download_document.
Test: serialized_document_opens_again.
