Rishikesh Gowda K K e75d1c741c feat(elf): decode Linux core dump process and memory mapping notes (#8830)
* feat(elf): decode Linux core dump process and memory mapping notes

Inspect Linux core dump note tables and decode structured metadata without
requiring external tools or debuggers:
- NT_PRPSINFO (type 3): decode process ID, parent ID, process group,
  session, UID, GID, execution state, filename, and command line arguments
  bounded by the text budget.
- NT_FILE (type 0x46494c45): decode mapped memory ranges (start_address,
  end_address, file_offset_pages) and mapped file paths with page size.
- NT_SIGINFO (type 0x53494749): decode faulting signal number, errno, and code.
- NT_AUXV (type 6): decode auxiliary vector pairs with known AT_* tag names.
- Support both 32-bit and 64-bit, little-endian and big-endian targets.
- Retain unknown core note types gracefully without partial success errors.
- Add comprehensive unit tests, fixtures, acceptance tests, and documentation.

* fix(elf): preserve raw path bytes and enforce auxv termination

* fix(elf): account for path hex text budget and enforce auxv trailing padding

* fix(elf): account for row and scan limits, ABI signal order, and lossless source IDs

* fix(elf): cache auxv padding scans, pre-charge entries, and isolate page-size test

morluto 7adfcc4467 fix: unify executable format ownership across artifact readers
Centralize ELF section and Godot trailer declarations while preserving caller admission policies. Route six PE entrypoints through canonical DOS ownership so relocation data cannot establish a PE header, and update NativeAOT interpretation identity and verifier dependency coverage.

morluto 9341b116ef refactor: consolidate binary artifact interpretation and fixture ownership
Share exact ELF program-header facts across nine consumers while preserving their admission and precision policies. Centralize conformance path and digest binding, retain verifier-specific checks, and route fixture-owner changes to CI qualification.

morluto 8b57dc630e fix(native): preserve metadata uncertainty in coverage
Explain unreadable ELF note section names without discarding complete note coverage. Keep export and PE import rows when only version or DLL-name metadata is unresolved, and stop claiming those retained rows were unreported.

Use native byte equality for the 4 MiB ELF extended-numbering source-preservation checks; generic deep equality enumerated every buffer byte and exhausted the test worker heap. The full fixture and byte coverage remain.

Validation: focused ELF note, native export, and PE import regressions plus complete CLI/MCP adapter files passed under the existing 512 MiB heap limit. Build, typecheck/lint, formatting, and documentation checks passed.

morluto 75a757d8ef fix(elf): distinguish compressed note storage from decoded notes
Refuse compressed note sections with typed unsupported-target semantics before framing or decoding, preserving stored-range checks and physical descriptor-offset provenance. Flutter retains independent build IDs with partial coverage when compressed notes are skipped. Verify the existing shared alignment fix with prefixed notes across classes and table kinds.

Fixes #6869
Closes #6563

morluto bd4f5e9c19 fix(parsers): preserve format evidence and caller input identity
Retain bounded FAT and offset-tagged PE observations through archive hashing,
classification, and content nodes. Preserve PyInstaller member paths according
to the observed carrier dialect and share APK v1 signing-name semantics.

Read SQLite's implicit sqlite_schema table without inventing a stored schema
declaration. Distinguish unsupported ELF numbering and decoded-name admission
from malformed data and fixed scan allowances. Preserve Sigrok basenames and
classify matching explicit input-format refusals at their owning boundary.

Validation: 554 distinct tests passed, 3 skipped across serial focused runs;
build, typecheck/lint, docs, formatting, and discovery (2141 files) passed.
Sigrok command-boundary simulators do not establish real-tool decoding.
Small repeated public PyInstaller CLI runs had equivalent inventory facts;
warm median elapsed 0.5431s before / 0.5426s after, with no speed claim.

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.

Matt Van Horn 2edf3b23c1 feat(elf): inspect PT_NOTE and SHT_NOTE tables (#4837)
Inspect selected ELF32/ELF64 PT_NOTE and SHT_NOTE declarations without executing
the artifact, retaining independent table identities, source ranges, descriptor
digests, GNU build-id/ABI fields and explicit coverage limitations.

Integrate mvanhorn's implementation and hardening with current main while
preserving byte-entropy registration and the Windows curated regression suite.
The maintainer follow-up uses ordinary merges/pushes, not history rewriting.

Executed validation: 96 focused/shared/docs tests, complete static/docs checks,
eleven real CLI/MCP pairs including GCC ELF32 and Clang big-endian PowerPC64,
and two actual Codex task traces checked against their Evidence. Full costs,
grader correction and verification limits are recorded in PR #4837.
