morluto 52ca222bd0 fix(il2cpp): preserve loader ownership and ABI field boundaries
Resolve pointer and scalar facts through their shared loader-aware owners before registration search or type rendering. Preserve unresolved names and attributes, read count fields at their declared width, and admit declared zero-fill registration tails without accepting unmapped bytes.

Cover relocation overlap and adjacency, loader-bound fields, ABI padding, nullable names, and CLI/MCP behavior; document format and verification limits.

morluto 8b3902d377 fix(native): own complete metadata mappings and ambiguity
Resolve Go pointer descriptors and strings across complete, consistent file-backed spans, including PE headers and adjacent ELF load ranges. Reuse the canonical image-mapping selection for native exports. Preserve existing gaps, alias, zero-fill and capacity refusals.

Forward parsed zero-fill ownership through IL2CPP relocation tables, destinations and mapped-span checks. Distinguish missing spans from ambiguous ownership in the shared mapping failure: unresolved relocation targets may remain unknown, while ambiguous raw registration bytes cannot be reused as a resolved count.

Validation: parser, provider, service, native-export, IL2CPP and public CLI/MCP regressions cover PE32/PE32+ headers, split ELF descriptors/contents, relocation count conflicts, ordinary unresolved targets and unchanged inputs. Authored carriers establish static parsing, not Windows loading or actual legacy Go linker emission.

morluto 99d2d7ad22 fix(parsers): retain independent facts and boundary identity
Share bounded ELF section-name decoding across native and note readers; retain read-only ranges and coverage reasons when names are unknown. Preserve ELF symbol-version bytes, dyld-bound method uncertainty, partial gRPC-Web trailers, and per-parent model identity checks. Compare GPU signatures as bytes and require a PTX module header. Share selected-path errno classification across EVM and BEAM.

Validation: 397 shared-parser tests passed (one existing skip), 5 MCP schema tests passed, 14 EVM error-mapping tests passed, and 23 protobuf CLI/MCP matrix cases passed across focused runs. Build, typecheck/lint, docs, formatting, and 2134-file discovery passed. Full EVM provider workflow remains locally unverified on Darwin arm64; format controls are synthetic.

morluto 5f702dd6cc fix(parsers): preserve format boundaries and query occurrence identity
Normalize parsed facts at their owning boundaries across PE exports and certificates, ELF section names, GPU bundles, IL2CPP generic types, dyld slice selection, source maps, environment replay, and JavaScript mapped arguments. Preserve partial facts and explicit unsupported cases; clarify the corresponding documentation.

Validation: 831 affected tests passed with one existing skip across 23 files; build, typecheck/lint, documentation, formatting, and 2133-file test discovery passed. Format controls are synthetic; real Unity, GPU, and ARM-device execution is unverified.

JANG BYUNGKUN 52d1a72af0 feat(il2cpp): link native methods and export Ghidra seeds
Link IL2CPP metadata names to native addresses and types through shared CLI/MCP workflows, with bounded queries and atomic Ghidra seed export.

Preserve the original implementation by 8rulerstar and follow-up correctness, resource, provenance, and CI dependency repairs. Verified against real Windows/Android artifacts, independent references, actual Ghidra, and focused CLI/MCP tests.

Fixes #5112.

JANG BYUNGKUN 21e0c580e7 feat(il2cpp): read member names, string literals and metadata versions 24 and 27 (#5326)
* feat(il2cpp): read member names, string literals and metadata versions 24 and 27

Adds field, property, event and parameter names with their owners, managed string literals, and the version 24 and 27 header layouts to inspect_il2cpp_metadata, with filtered pages for the new collections. Member decoding yields between row batches like the other row readers.

* fix(il2cpp): bound metadata expansion and query parameter owners

* test(il2cpp): cover nonempty property and event tables

JANG BYUNGKUN 833136507d feat(il2cpp): inventory Unity IL2CPP global-metadata images, types and methods (#3807)
* feat(il2cpp): inventory IL2CPP global-metadata images, types and methods

Add inspect_il2cpp_metadata (CLI inspect-il2cpp-metadata), a read-only
in-process decoder for unencrypted Unity global-metadata.dat version 39.
It reports header sections, serialized index widths, images, type
definitions (nesting from the nestedTypes section) and method names.

Unrecognized magic and other versions are unsupported; damaged headers,
overlapping sections, inconsistent record sizes, out-of-range indices and
invalid strings fail with a reason code and no partial success. MCP
detail summary retains the complete Evidence and pages rows through
inspect_analysis_view kind il2cpp-metadata.

Adds an opt-in verify:il2cpp:metadata -- --metadata PATH check.

* feat(il2cpp): deliver metadata summaries by default over MCP

A 112,232-method file produced a 10.5 MB complete response, above the
10 MiB stdio budget. Default MCP delivery is now the retained summary;
detail complete stays available, and the one-shot CLI requests it.

* fix(il2cpp): reject shifted strings, nesting cycles and method owner drift

Review fuzzing showed that moving the strings section offset by one byte
silently renamed every image, type and method. Name indices must now start
a string, which also bounds total decoding by the section size.

Nesting cycles and methods whose declaring type disagrees with the owning
type range are rejected instead of returned. Adds service, shutdown and
index-width coverage, and moves environment-specific measurements out of
the public guide and tool description.

* feat(il2cpp): decode global-metadata versions 29 and 31

Unity 2022.3 writes version 29 or 31 metadata: a 256-byte header of
(offset, size) pairs, fixed 4-byte indices, type records with
elementTypeIndex, and method records that gained returnParameterToken in
version 31. Record counts come from section sizes and must be whole.

Sections report a null count for these versions and index widths report
fixed-width-version. Image, type and method rows keep the same shape, and
the string, nesting and method-ownership checks apply to every version.

* fix(il2cpp): bound report size before serializing and tighten coverage

Rows share decoded names, so a 130 KB file could expand into gigabytes of
JSON before the 64 MiB budget check, ending in an internal RangeError. The
provider now refuses from a lower bound on the serialized rows first.

The decoder also rejects non-empty sections inside the header, methods
outside their declaring type's range and overlapping image type ranges, and
keeps a leading byte order mark in names. Layouts now carry one indexing
mode instead of two coupled flags, and the tool description explains
nested_type_start.

* fix(il2cpp): refuse oversized metadata before decoding rows

Address review findings on the IL2CPP metadata inventory:

- check a lower bound from header row counts before any row object is
  allocated, so a large rejected file no longer builds every row first;
- validate sealed parent Evidence and count its rows once per report
  instead of on every inspect_analysis_view page;
- decode version 39 fixtures with 2- and 4-byte type-definition,
  generic-container and parameter indices.

* docs(il2cpp): attach the decoder comment to readIl2cppMetadata

* fix(il2cpp): deliver complete rows by default like the other inspection tools

inspect_il2cpp_metadata defaulted to detail summary, the only inspection
tool to do so. Omitted detail now returns every row inline, as
inspect_artifact, decode_interface_builder and the capture tools do;
summary stays one argument away and the guide, CLI reference and skill
reference say to select it first for large games, whose complete MCP
delivery is refused at the stdio budget with retained Evidence.

* test(il2cpp): cover narrow-width -1 sentinels and fix the skill's default

An empty image stores its type start as the all-ones value of a one- or
two-byte index; the decoder reads it as -1, but no fixture exercised it,
so removing either conversion passed the suite. The fixture can now append
an empty image, and both widths decode it. The skill still described a
summary default; it now says to select summary first, as the guide does.

* docs(il2cpp): request summary explicitly in the summary example

* chore(il2cpp): hash the verifier metadata through owned file resources

* fix(il2cpp): count escaped name length without building the escaped string

* fix(il2cpp): keep the verifier's check failure and small-table last page

* feat(domain): count JSON string length without building the escaped string

* fix(il2cpp): keep descriptor cleanup owners and share the JSON length count

* test(domain): give the backslash case real backslashes

* fix(il2cpp): select the CLI path and finish the command like the other tools

Follow main's absoluteCallerPath (#4067) and pass the command signal to finishAnalysisCommand.

* fix(il2cpp): select the verifier input path like the CLI

Use absoluteCallerPath (#4067) so a path with a symlink followed by .. names the same file the CLI and MCP inspect.

* feat(il2cpp): add compact composable metadata queries

Retain source-indexed Evidence for filtered batch and field queries. Bound representation growth before serialization, yield decoding for cancellation, and share CLI Evidence publication with desktop inspection. Verify public Unity metadata against independent byte and managed-DLL oracles and exercise actual stdio SDK workflows.

* fix(il2cpp): retain the validated metadata header magic

* test(il2cpp): remove obsolete execution wording exception

* fix(artifacts): preserve export selection and completed source facts
