* feat(artifacts): add U-Boot legacy uImage reader (part of #7129)
Recognize legacy uImages by their 0x27051956 magic and inventory them as containers: 64-byte header facts (arch/os/type/compression raw and named, load/entry addresses, name, timestamp) with header and data CRC32 verified, stored payload extractable as payload.bin, and multi-file images split from the stored size table into image-<n>.bin. Compressed payloads stay as stored; nothing is executed or decompressed. Wires the format through classification, the artifact reader dispatch, extraction, and the evidence/snapshot format vocabularies. Related to #7129 (uImage part only); HEX/SREC and FIT are out of scope.
* fix(uimage): preserve aligned component ranges and exact header facts
* fix(uimage): retain buffered members through consumption and cancellation
* fix(uimage): preserve active read and validation failure precedence

* feat(artifacts): read UnityFS AssetBundle containers
inspect-artifact and extract-artifact now recognize the UnityFS signature
and treat format versions 6 through 9 as containers. Header facts (format
version, player/engine strings, declared size, dataflags, blocks-info
bounds and the declared 16-byte data hash) are retained alongside a
directory of CAB-* and .resS members. Member bytes stream on demand:
only the blocks covering the requested member are read and decompressed
with bounded expansion and cancellation.
Bundles declaring asset-bundle encryption keep header facts and report
unknown directory coverage. LZMA blocks-info reports unknown coverage;
LZMA member reads fail as unavailable while the directory stays
readable. Malformed counts, out-of-stream members and declared sizes
beyond the file fail as format errors. UnityFS classifies by bytes in
root detection, inventory graph construction and desktop inspection,
which emits a unityfs-header fact.
Validation: tsc --noEmit, oxlint (no new findings on touched files),
17 reader tests covering LZ4HC/uncompressed tables, blocks-info at end,
format 6 without padding alignment, multi-block members, malformed
input, unsupported compression, cancellation and abandoned streams;
full artifacts/domain/conformance suites pass. Verified against one
real YooAsset bundle (Unity 2021.3.32f1, format 8, LZ4HC): the
streamed SerializedFile contained its managed assembly byte-identical
to a UnityPy extraction. Other producer variants unverified.
* fix(unityfs): own bounded member reads and preserve partial evidence
* refactor(unityfs): clarify producer revision flag decisions
* fix(artifacts): preserve coverage authority and bound UnityFS block work

* feat(artifacts): inventory and extract Intel HEX and Motorola S-record regions
open_binary refused Intel HEX and S-record programming files as an
unsupported format, so inspect_artifact and extract_artifact could not
answer which bytes load at which addresses.
Recognize both encodings by a fully valid first record and decode them
statically into address-contiguous regions, each an inventory entry named
0x<start>-0x<end>.bin and extractable as raw bytes. Root format_metadata
records the encoding and variant, record counts, unique and duplicate
bytes, address bounds, termination, declared start address, S0 header and
validated S5/S6 count. Gaps are never filled; start addresses are declared
facts, not proven entry points.
Checksum, record-type, byte-count, line-length, overlap-conflict, address
wrap and post-termination errors fail closed with the line number; a
missing termination record leaves coverage unknown. Decoding is bounded by
a 128 MiB file ceiling (decoded bytes are at most half the file and are
reserved after the size check) and 65,536 address-discontiguous runs.

Replace overlapping traversals with one bounded relationship owner. Preserve superview direction, treat conflicting or unsupported registry placement as unknown, and retain source facts and coverage.
Keep historical inventory summary variants with their projection owner and share embedded PCK trailer observations while preserving each reader’s admission policy.
Record packed and unpacked ASAR file declarations at the reader boundary and compare known storage changes without treating historical omissions as packed. Preserve known differences when bytes are unavailable and retain existing integrity precedence.
BREAKING CHANGE: ASAR file occurrences may now contain unpacked: false. Consumers that validate only true must accept an optional boolean; absent historical fields remain unknown.
Reuse completed embedded-format observations only after validating the admitted file identity and state, and centralize reader construction across inventory and extraction. Preserve early refusal, selected-path checks, ZIP ownership, and each operation's traversal policy. A source changed between preflight and inventory now fails integrity validation.
Distinguish omitted slice fields from declarations that cannot be interpreted, and preserve their source in native results and artifact limitations. Keep structural fallback and capacity failures explicit.
Preserve producer-supported recovery guidance after an existing-image DMG attachment refusal, without borrowing or detaching existing mounts. Keep diagnostics, root provenance and unknown coverage; centralize guidance ownership and run the real mounted-image regression in macOS CI.

Retain a limitation when ASAR block integrity fields are present. Whole-file hash verification does not establish block verification or Electron runtime acceptance.
Validated inventory and extraction workflows, including partial and malformed block declarations.
Carry reported algorithms and hashes into listing limitations when the declaration cannot be compared, retaining the existing verification and extraction policies. Bound escaped text before allocation.
Validated ASAR inventory, extraction, cleanup and MCP workflows; prior code omits the declaration details.
