Apple's crash report JSON documents termination.byPid, byProc and flags, the body's parentPid, and the metadata line's build_version and platform. The parser shapes did not list them, so they were reported only by name in unlisted_keys / unlisted_body_keys and their values were dropped: a watchdog kill no longer said which process ended it, and process kept parentProc without its pid. #4297 asks for termination members beyond namespace/code/indicator to be retained as recorded, and docs/apple-ips.md says documented fields are reproduced. They are now kept: termination.by_proc, termination.by_pid and termination.flags, process.parent_pid and metadata.build_version / metadata.platform. The integers are recorded integers, so they count toward max_integer_text_bytes and a type mismatch is recorded like the other fields.

Apple IPS crash reports
inspect_apple_ips / inspect-apple-ips answers whether one selected local
Apple .ips file is a crash report (bug_type string "309"), which process,
exception, and termination facts that report records, which threads and
usedImages rows it lists, and which documented crash classes its strings
match. It reads the file without executing a target and does not require Xcode,
atos, a disassembler, or pwntools.
rea inspect-apple-ips /absolute/path/to/report.ips --json
The CLI resolves relative paths against the caller's working directory. MCP requires an absolute filesystem path and preserves that exact selection:
{
"name": "inspect_apple_ips",
"arguments": { "path": "/artifacts/report.ips" }
}
Observations
The inline Evidence result contains the artifact path, SHA-256, and byte length.
metadata is the first-line JSON object. bug_type stays a string. The crash
body is parsed only when that string is "309". Other types, including "288"
stackshots, return no crash result.
process, exception, termination, faulting_thread, threads, and
images reproduce documented body fields when present, including each image's
name and each frame's symbolLocation (as symbol_location, the byte offset
from the start of recorded_symbol). termination keeps the terminating
process as by_proc and by_pid and its flags; process.parent_pid keeps
parentPid next to parent; and metadata keeps build_version and
platform. Integers keep their
decimal literals and a hexadecimal form, including arm64e registers above
2^53. Frame roles follow the recorded frame index: row zero of the resolved
faulting thread is faulting_instruction, row zero of other threads is
current_instruction, and later rows are return_address. Each runtime
address uses that row's own image base and offset. The recorded inline flag
does not supply a missing offset or authorize borrowing another row's address.
When faultingThread is missing or does not resolve to a recorded thread
object, row-zero roles are unknown; the recorded lookup remains available.
A translated process records Rosetta's registers in a nested
threadState.rosetta object; each one is reported as rosetta.<name> and
counts toward the register budget. A
