Syed Rishad c374c2fe72 fix(ghidra): preserve partial dossiers on decompiler failure (#4650)
Preserve listing-backed facts and explicit unavailable decompiler facets when one function fails. Retain Evidence while excluding transient failures and derived workflows from snapshot reuse; keep healthy cache reuse and owned cleanup semantics.

Fixes #4644.

The one -Niuandmorluto 0baad58e60 feat(ghidra): admit RISC-V ELF analysis through a pinned generic lane (#2151)
* feat(ghidra): admit RISC-V ELF analysis through a pinned generic lane

Refs #2063.

Recognize `EM_RISCV` (243) as a provider-neutral family that carries its own ELF
facts, and bound the first Ghidra lane to little-endian `ET_EXEC` images that
declare the double-float ABI, pinned to `RISCV:LE:32:default` or
`RISCV:LE:64:default` with the `gcc` compiler specification.

Ghidra 12.1.4 is not reliable without the pin: its `riscv.opinion` pins
`variant="default"` for the 64-bit constraint and leaves the 32-bit constraint
with the comment that the loader "must choose between 'default' and 'AndeStar'
variants". Measured on the installed release tree, a source-owned generic RV32
ELF with no Andes declaration imports as `RISCV:LE:32:AndeStar_v5:gcc`, while
RV64 resolves to `RISCV:LE:64:default:gcc`. The lane therefore states the
language per width and refuses any caller-selected processor outside it instead
of inheriting the header guess.

Refusals name the declaration rather than falling back to a guessed profile:
big-endian images (Ghidra 12.1.4 ships no big-endian RISC-V language),
non-`ET_EXEC` images, `EF_RISCV_RVE`, `EF_RISCV_TSO`, and every float ABI other
than double, which the pinned generic compiler specifications model. The raw
e_flags bits stay in Evidence as declarations, not as instruction semantics.

Family recognition now has one owner for the ELF-metadata families:
`ELF_METADATA_ARCHITECTURES`, `isElfMetadataArchitecture`, and
`HeaderArchitecture` replace ten `Exclude<BinaryArchitecture, "mips">` sites that
would each have needed a second hand-edited member. `ghidraPinnedLanguage` is
that owner for the import commitment: the session readback previously re-derived
only the MIPS pin, so a profile committing any second pinned language failed with
a language-mismatch error before the bridge started.

Hopper and IDA refuse RISC-V by name, matching the MIPS wording. Caller-supplied
raw-binary entry keeps its existing four-family list; this lane is ELF-header
admission only.

Verification on macOS 15.7.7 arm64, Node 24.18.0, Ghidra 12.1.4 PUBLIC and JDK
21.0.12.1, with the host decompiler built from the release sources for
`os/mac_arm_64`: `npm run check` passes; `npm run test:fast` passes 396 test
files; `npm run verify:test-discovery` discovers all 917 test files exactly once.
Source-owned RV32 and RV64 double-float `ET_EXEC` fixtures complete
`rea analyze --provider ghidra` and `rea decompile rea_riscv_entry`, committing
`RISCV:LE:32:default` and `RISCV:LE:64:default` with `language_selection:
provider-pinned-v1`; the soft-float RV64 shape is refused with the named
float-ABI reason, and the full refusal matrix including the RV32 and
width-mismatch shapes is covered by unit tests. No `verify:ghidra:riscv` lane
script is included in this change; the runs above were performed manually against
the installed engine. Fork pull requests receive no CI check runs, so the
real-provider scope above is the evidence available for review.

* fix(ghidra): bound the RISC-V lane by declared flags and document it

Address review feedback on #2151.

`e_flags` bits outside `EF_RISCV_RVC | EF_RISCV_FLOAT_ABI` are now refused with
the offending value named, so a reserved or newer producer declaration cannot
enter the verified generic lane by falling through the RVE, TSO and float-ABI
checks.

Admission reads `e_type` only, so the refusal text no longer calls `ET_EXEC`
static: a fixed-address declaration does not establish static linkage, and
`PT_INTERP` and dynamic dependencies are not inspected. The session records that
boundary as a limitation rather than inferring a load model.

Add `docs/ghidra-riscv.md` in the shape of the MIPS lane guide (admission
boundary, refusal table, why the language is pinned per class, Evidence fields,
and what the fixtures do not establish), and correct
`docs/firmware-analysis.md`, which still told users that MIPS and RISC-V
decompilation had not been added.

Verification after the change: `npm run check` and `npm run docs:check` pass; the
RISC-V module tests pass (17 lane cases plus 9 parser cases); on Ghidra 12.1.4
with JDK 21.0.12.1 the RV32 and RV64 double-float fixtures still analyze and
decompile with `RISCV:LE:32:default` / `RISCV:LE:64:default` and
`language_selection: provider-pinned-v1`, the soft-float fixture is still refused
by name, and the new linkage limitation appears in the emitted Evidence.

* fix(ghidra): align RISC-V pinning with admission

Reuse the complete lane admission boundary when selecting a language, retain unsigned unsupported flag bits in diagnostics, and derive float ABI metadata from the source declaration.

* test(ghidra): verify RISC-V CLI and MCP workflows

Build source-owned RV32/RV64 fixtures with Clang and LLD, establish independent ELF and symbol facts with LLVM readelf, and verify real provider evidence, instruction bytes, calls, decompilation, schema projections, snapshot replay, refusal diagnostics, source immutability and cleanup.

Verified on macOS ARM64 with Ghidra 12.1.4, JDK 21 and LLVM/LLD 23.1.2. Dynamic linkage, big-endian, Andes and RVE/TSO workflows remain unverified; ISA attributes are not inspected.

Syed Rishadandmorluto 3749ccec47 feat(ghidra): recover signed AArch64 relative jump tables (#1592)
* feat(ghidra): recover signed AArch64 relative jump tables

Generalise the AArch64 relative-table matcher to signed byte/halfword entries, UXTW indexes, byte or LSL #2 offsets, B.CS/B.HS bounds and a CBZ route for zero entries. Cross-check it against Ghidra's own load table when one exists, and add a fixture modelled on the RenderScript blend kernel.

morlutoandCursor Agent 5cbf06c7ad fix(ghidra): admit the 12.1 line and the install's JDK range (#840)
* fix(ghidra): admit the 12.1 line and the install's JDK range

The provider treated the verified Ghidra 12.1.4 build and JDK 21 as the only
legal installation, so a working 12.1.x package or a newer JDK was rejected
before analysis started.

Admission now follows the 12.1 release line and application.java.min/max.
A compatible build other than 12.1.4 keeps its observed version and records
that the bridge was verified against 12.1.4.

Fixes #821

* fix(ghidra): stop pinning the NativeAOT build to one version string

The build script still rejected every Ghidra release except the literal
12.1.4 and every javac except major 21. It now accepts the 12.1 line and
javac 21 or newer, compiles with --release 21, and records the observed
Ghidra version. The JADX engine version uses the audited release constant.

* fix(ghidra): report unverified builds on analysis results

Session open uses health only as a startup gate and discards that
execution, so the unverified-build limitation never reached CLI or MCP
results. Attach it to every Ghidra execution for that install.
