* fix(apple): preflight XML plist nesting before keyed archive decoding
inspect_keyed_archive documented a 128-level nesting limit, but the XML
plist path reached recursive decoding before any depth check: plist and
the prototype-key traversal in parseXmlPropertyList recurse once per
nesting level, so a ~75 KiB, 3000-level XML plist exhausted the call
stack and reported Maximum call stack size exceeded instead of the
bounded-resource limit that shallower over-limit documents (129, 200)
already produced. The CLI classified both as truncated, so no crash or
classification bypass was involved; the diagnostic was the defect.
Reject excessive nesting in parseXmlPropertyList before any recursive
pass, using the projection's own limit (MAX_PLIST_DEPTH) so the error is
identical to the one projectPlistValue raises: callers keep the
limit/truncated classification with no error-handler translation. Depth
counts values the way the projection does - container members nest one
level deeper, dictionary keys name members rather than nesting, and a
self-closing element is the value at its own level - so the guard
rejects exactly the documents the projection rejected, at the same
boundary, and every in-limit document decodes unchanged. The guard sits
at the shared decoder boundary, so Interface Builder, app Info.plist
resolution and native inspect_plist gain the same deterministic limit;
the binary plist path keeps its existing expansion preflight.
Binary plist behavior, ordinary XML decode, __proto__ omission counting,
and archive digest/Evidence provenance are unchanged. OpenStep
autodetection is untouched by this guard, as the existing Interface
Builder preflight also scopes its depth check to XML.
Regression coverage: decoder unit tests at and just past the limit for
dictionary and array nesting with self-closing and opaque markup,
module tests through decodeKeyedArchiveBytes including a valid
NSKeyedArchiver XML envelope at the limit, a production-boundary test
through inspectBundleKeyedArchive, and the compiled public CLI
reporting code truncated / reason limit for a 3000-level plist.
* fix(apple): check XML nesting against parsed element structure
Reuse the iterative XML decoder document for depth preflight and prototype-key lookup. Bound recursive plist wrappers alongside dictionaries and arrays without interpreting markup inside attributes or DOCTYPE declarations as values.
Validated with 104 focused tests including compiled CLI, MCP prototype-key, and Interface Builder coverage; npm run check and verify:test-discovery passed. No real-provider verification was run.
