* feat(ghidra): admit 32-bit big-endian PowerPC ELF Recognize EM_PPC as a provider-neutral `powerpc` family that keeps its ELF class, byte order, type and flags, and admit ELF32 big-endian ET_EXEC through a bounded Ghidra lane. ELF64, little-endian, relocatable/shared objects and EF_PPC_EMB are refused with a specific reason; Hopper and IDA do not gain PowerPC support, and Windows Ghidra P0 is unchanged. Ghidra's ELF loader selects PowerPC:BE:32:e500:default for a plain EM_PPC header, which misreads 750-family code. The lane binds PowerPC:BE:32:default/default in the profile (language_selection "admitted-lane-v1"), imports with it and checks the reported language. A language set through REA_GHIDRA_LANGUAGE_ID still replaces the lane default. Add a source-owned fixture, fixed-encoding probe, GNU readelf cross-check and the optional `verify:ghidra:ppc` real-provider lane, plus docs/ghidra-ppc.md.

Source-built conformance fixtures
These sources are deliberately small semantic oracles for REA providers. Run
npm run verify:fixtures on macOS or Linux to compile them into the ignored
build/conformance/ directory, emit a hash-and-toolchain manifest, and verify
their platform-native symbols and strings with local command-line tools. The
portable C, version, and large-inventory fixtures build as Mach-O on macOS and
ELF on Linux; Objective-C, Swift, and N-API-like fixtures remain macOS-only.
Only source files are versioned. Generated binaries, generated large-fixture
source, debug information, and manifests must remain under build/.
ghidra/inventory.c is also compiled into temporary Linux ELF debug and
stripped variants by npm run verify:ghidra. It fixes local functions, external
puts linkage, defined strings, and writable/executable memory needed to prove
the read-only Ghidra inventory contracts without committing a binary.
scripts/create-ghidra-windows-fixture.mjs separately emits a deterministic,
ignored native x86-64 PE application for the controlled Windows Ghidra P0 lane.
The generator and fixed SHA-256 are versioned; the .exe is never committed or
executed. npm run verify:ghidra:windows uses it to verify the admitted read-only operation inventory,
digest linkage, transport, and cleanup on the self-hosted real-Ghidra runner.
The C fixture fixes a known call chain and strings. The version pair fixes an added symbol, changed string, and changed call relationship. The generated large fixture contains 1,205 uniquely named functions and strings to verify that providers return complete inventories. Objective-C, Swift, and N-API-like fixtures provide metadata-oriented inputs without package or network dependencies.
readiness/ adds source-only generated JavaScript CLI and Electron fixtures for
the repository's reconstruction-readiness verifier. npm run verify:readiness
combines them with the compiled native fixtures, exercises CLI and MCP parity
for real analysis operations, and checks the internal machine-readable report
documented in docs/reconstruction-readiness.md.
