morluto 7d79a6a85b fix(verify): own asynchronous Ghidra prerequisite inspection
Await installation inspection through one shared helper with a real resource
scope at all 13 verifier call sites. Retain exact close owners, complete cleanup,
and preserve primary plus cleanup failures. Keep compiler-only loading lazy and
use the namespace workflow's selected environment.

Add admission contract and native-file lifecycle controls, plus a real script
prerequisite rejection check. Controlled Java/header observations do not qualify
a real Ghidra engine. Combined verification selection: 122 tests passed across
five files; static/format/discovery passed; two scoped source reviews clear.

Abdul Samad Siddiqui a40ee741c2 test(ghidra): align MIPS verifier ABI and snapshot expectations
Fixes #3415. Retain independently inspected GNU attribute facts and compare exact snapshot wire fields. Preserve strict metadata comparisons, specific incomplete-ABI refusals and source immutability checks.

Original implementation by @AbdulSamad94.

BaaRai a4b8e9ccee feat(ghidra): admit recordless legacy MIPS32 ELFs with a pinned 32-bit language (#1898)
* feat(ghidra): admit recordless legacy MIPS32 ELFs with a pinned 32-bit language

Firmware built with pre-ABI-flags GNU toolchains declares EF_MIPS_ARCH_32
with an unspecified ABI field and no PT_MIPS_ABIFLAGS record. The lane
refused them before provider selection, and Ghidra's own header
auto-selection picks a 64-bit R6 language for exactly these files.

Admit ELF32 ET_EXEC headers with EF_MIPS_ARCH_32 or EF_MIPS_ARCH_32R2,
an unspecified ABI field, EF_MIPS_ABI2 clear and no observed ABI flags
record. o32 is recorded as an inferred analysis assumption
(mips_abi_basis), floating-point ABI semantics stay unverified, and the
existing refusals (FP64, NAN2008, ASEs, machine variants, ELF64) are
unchanged. The profile pins -processor MIPS:<LE|BE>:32:default through a
provider-pinned-v1 selection the bridge-reported language_id is checked
against after import; a caller-selected REA_GHIDRA_LANGUAGE_ID still
wins. The lane identity is versioned
elf32-exec-arch32-legacy-pinned-v1.

verify:ghidra:mips gains a recordless legacy round for both byte orders
that strips the ABI record declarations from a real mips32 fixture,
checks REA's interpretation against GNU readelf, asserts the pinned
language after import and the retained assumption limitations through a
snapshot round-trip.

Fixes #1620

* fix(ghidra): require an inspected absence for the recordless MIPS lane

Address review: undefined ABI flags means the record was not inspected,
not that none exists. Only an inspected absence (null) establishes the
recordless legacy admission; a merely unobserved record keeps its
specific refusal. Also document the legacy admission and its pinned
language in the MIPS provider guide.

* fix(ghidra): tighten the recordless MIPS admission boundaries

Address review: a recordless-looking header whose ABI-record inspection
left declaration sources unexamined (carved ELF with a partial section
table and no program-header record) no longer establishes the recordless
admission; it is refused with the inspection limitation retained. An
EF_MIPS_ARCH_32 header that declares an ABI is refused rather than
relabeled through the 32R2 declared-ABI lane.

* fix(ghidra): reject EF_MIPS_ABI_ON32 from the recordless MIPS lane

Address review: bit 0x40 declares the old n32 ABI. A recordless header
carrying it was admitted with the inferred-o32 assumption even though
the header itself declares n32; the recordless shape now requires the
bit clear and refuses it with a specific constraint.

* fix(ghidra): keep recordless relocatable MIPS objects off the legacy lane

The recordless admission now requires ET_EXEC: the lane and its
verification cover executable firmware images, and a recordless ET_REL
object must stay on the declared-ABI path instead of inheriting the
inferred-o32 assumption under an executable lane id. The ABI-record
requirement paragraph is scoped to the declared-ABI lane so it no longer
contradicts the recordless admission documented above it.

* fix(ghidra): name the ET_EXEC scope for recordless objects and probe the legacy lane

A recordless relocatable object is not an incomplete inspection, so its
refusal now names the ET_EXEC scope of the legacy admission instead of
claiming unavailable ABI headers remain unknown. The recordless legacy
verifier round reads the probe pair and applies the full assertMipsProbe
oracle like the standard round, and its report keeps the independent
GNU readelf receipt beside the fixture facts.

* fix(ghidra): retain the concrete ELF32 legacy compiler pin

* fix(ghidra): bind legacy profiles to fully admitted targets

Aurelio Bernal c462a4ebd3 fix(scripts): pass MCP callTool timeouts as request options (#2387)
@modelcontextprotocol/client 2.3.1 declares callTool(params, options).
Three verifiers still used the v1 shape callTool(params, undefined,
{ timeout }), so the third argument was dropped and those calls ran
under the SDK's 60 s default instead of the 150-180 s they request.
Pass the options second.

Aurelio Bernal 5e219de441 feat(ghidra): admit soft-float MIPS32r2 ELF with integer-register float storage (#1949)
* feat(ghidra): admit soft-float MIPS32r2 ELF with integer-register float storage

Soft-float o32 executables (Linux kernel builds, bare-metal firmware) were
refused because their ABI flags record declares no CPR1 and FP ABI 3.
Ghidra's MIPS32 compiler specifications model only hard-float o32, so typed
float/double signatures (DWARF) would be bound to $f12/$f14/$f0 and the
decompiler loses the real dataflow: `return sel ? a : b` decompiled to
`return in_f0;`, and callers passed phantom FPU inputs.

Admit ELF32 ET_EXEC o32 MIPS32r2 targets whose ABI record declares soft-float
with no CPR1, and commit `mips_soft_float_storage: o32-integer-registers-v1`
in their analysis profile only (hard-float profile digests are unchanged).
ReaGhidraMipsSoftFloat.java runs after auto-analysis and, for each function
with a float/double formal type, either keeps the types with the storage
Ghidra's o32 model assigns to a same-size integer (pair alignment, stack
spill), or, for auto-parameters such as hidden struct-return pointers, swaps
float types for same-size integers under dynamic storage. No function is left
on hard-float storage. The report is written last; the provider client
requires it exactly when the profile commits the policy and refuses the
session before any operation otherwise.

Verification: real Ghidra 12.1.4 lane (verify:ghidra:mips) now builds
hard- and soft-float fixtures in both byte orders and checks exact
parameter/return storage through inspect_native_api, caller constants,
snapshot profile and Evidence outcome; test:fast, verify:package and an
installed-tarball soft-float run pass.

* fix(ghidra): model soft-float MIPS as a prototype for every typed callable

Review feedback on #1949: rewriting storage per Function left external
functions and indirect calls through typed function pointers on Ghidra's
hard-float o32 prototype, which still read $f12/$f14/$f0 while the session
reported success. A negative control confirms it: without the change,
`(*rea_mips_soft_callback)(8.5f, 9.5f, sel)` decompiles to
`(*rea_mips_soft_callback)(in_f12, in_f14, sel)`.

ReaGhidraMipsSoftFloat.java now derives a `__rea_soft_float` prototype from
the program's own default o32 model (encoded, float pentries and
float-consuming rules removed, so byte-order-specific aggregate rules and the
hidden struct-return pointer are kept), installs it as a specification
extension, and assigns it with dynamic storage to every non-thunk function,
external function and function-pointer definition whose formal types use
float or double. Thunks follow their targets. Float types are kept
everywhere, so the integer-retype fallback is removed. The script fails
without writing its report if the derived prototype or any reassigned
function still uses an FPU register.

The policy becomes `o32-soft-float-prototype-v1` with a
{functions, definitions} report. The soft-float fixture adds an indirect
call through a typed pointer; the real-Ghidra lane requires its constants
with no FPU inputs and the struct return's `float scale` in $a1.

* test(ghidra): pin ODDSPREG acceptance for soft-float MIPS ABI records

Review on #1949 suggested requiring flags1 == 0 for soft-float, since MIPS_AFL_FLAGS1_ODDSPREG names CPR1 registers. GCC 5.2 kernel modules, LLVM/Rust firmware and Clang -msoft-float objects all record flags1 = 1 with FP ABI soft-float: it is the MIPS32 o32 toolchain default and selects nothing without CPR1. Keep accepting it, say why at the check, and test that soft-float with ODDSPREG is admitted while any other general flag is refused.

Jay-Alexander Elliot bddddccdee feat(native): admit bounded MIPS ELF analysis through Ghidra (#1362)
* feat(native): admit bounded MIPS ELF analysis through Ghidra

Retain MIPS ELF identity and interpretation through Evidence and snapshots.
Keep provider admission bounded to ELF32 ET_EXEC o32 MIPS32r2, without
implicitly widening Hopper, IDA or Windows P0 coverage. Add source-owned
fixtures and an optional real-provider verifier; real Ghidra verification
remains pending in this contribution environment.

Refs #718

* fix(ghidra): bound MIPS floating-point mode admission

Reject explicit EF_MIPS_FP64 and EF_MIPS_NAN2008 declarations until their
semantics have a real-provider verification lane. Add PSP PRX/Allegrex,
o64/EABI and floating-point-mode refusal regressions. Document that the
header gate is not a full .MIPS.abiflags check and advance the profile lane
identity to invalidate older interpretation bindings.

Validation: 24 standalone checks against the transpiled production profile
module passed; the two new flag cases failed before this change. Clang 17
and LLD compiled the source-owned fixture for both endian targets. The
complete Vitest/typecheck suite and real Ghidra verification remain pending.

Refs morluto/rea#718; PSP support remains follow-up morluto/rea#1330.

* fix(native): validate MIPS ABI records before Ghidra admission

Read bounded ELF32 PT_MIPS_ABIFLAGS and SHT_MIPS_ABIFLAGS records through
the already-open target handle. Preserve declared ABI fields, reject
conflicting/duplicate/truncated records, and keep missing records unknown.
Wire inspection into target resolution before provider selection. Require
compatible declarations for the deliberately narrow Ghidra lane and bind
all ABI fields into profile identity (v3) for snapshot invalidation.

Clang 17 produced eight source-owned fixtures spanning both byte orders
and FPXX/FP32/FP64/soft-float modes with identical ELF header flags. The
new reader and policy distinguish them. 24 focused regression test bodies
passed after TypeScript transpilation using node:test in place of Vitest;
strict isolated TypeScript checking of the reader and target/result types
passed. These are limited checks, not full Vitest/project typechecking or
real-Ghidra verification, which remain pending.

Advances morluto/rea#718. PSP/Allegrex remains morluto/rea#1330 follow-up.

* fix(native): repair MIPS integration boundaries and test resolver behavior

Keep ELF targets out of Hopper Mach-O preparation and scope existing PE fixture types correctly. Move ABI tests into the filesystem boundary lane, use shared cleanup, add resolver regressions, apply the pinned formatter, and register the real MIPS verifier through the existing package-command pattern. Validated with repository-pinned Node/npm, check:ci, actual focused Vitest, discovery and docs:check. Real Ghidra conformance remains pending.

* fix(test): honor caller-selected JDK in real MIPS verification

* test(native): strengthen MIPS Ghidra conformance

Cross-check the source-owned fixture with bounded GNU readelf inspection, compare production ELF/ABI interpretation and independent symbol addresses, and verify effective Ghidra language/compiler identity through existing public operations. Add a source-owned fixed-encoding probe for immediate and conditional branch checks plus global/string byte assertions.

Add 16 assertion/producer-boundary regression cases without widening production admission, changing provider contracts, or introducing proprietary dependencies. Local focused suite: 99 passed, one existing root-permission test skipped. Typecheck, lint/module boundaries, formatting and 700-file discovery pass; full hosted checks and real Ghidra verification remain pending for this checkpoint.

* fix(ghidra): preserve native-tool architecture checks after MIPS integration

The conflict-free upstream merge failed TypeScript compilation because includes on the union of MIPS-only and other architecture arrays requires never. Use equality-based membership without casts or changing accepted native hosts. Extend the existing native-decompiler rejection table with a MIPS executable at a Linux x64 tool path; retain upstream FAT and unknown-header behavior. Hosted verification follows this commit; no success is claimed yet.
