Before submitting
Area
Native analysis or decompilation
Current limitation
REA integrates three deep providers (Hopper, Ghidra, IDA), but a session binds exactly one.
open_binary.provider_id"selects one deep provider ... the binding remains stable until close or an explicit switch" (src/contracts/sessionToolContracts.ts), andBinarySessionowns a single active target whose switch "tears down the active provider client" (src/application/binary/BinarySession.ts).procedure_pseudo_code,batch_decompileandanalyze_functiontake no provider argument, and the CLI's--provideraccepts one provider ID orauto.compare_functionsacceptsanalyze_functionEvidence from two different providers, but then returns thepseudocodeandassemblydimensions asunknownwith null digests and only character counts ("Exact text comparison requires one provider identity."), so the texts are not in its result (src/domain/functionComparisonDimensions.ts). It has no CLI command.To read one function's pseudocode from two providers today, an MCP user opens with provider A, runs
analyze_function, re-opens with provider B (which discards the binding to A and imports the target again), runsanalyze_function, and lines the dossiers up by hand. A CLI user runsrea decompile PATH PROC --provider A --jsonand again with--provider B. Nothing checks that both providers resolved the same function, and nothing keeps the outputs together with their provenance.Use cases
Desired outcome and success criteria
One CLI command and one MCP call take a target, one procedure selector and two or more provider IDs, and return one entry per provider in request order. Each entry has the provider's identity, version and analysis profile; the entry address and name it resolved; its pseudocode text exactly as produced, or
null; its own limitations; andokor a typed error. The result never ranks the texts or claims they are equivalent.Success criteria:
not_configured,target_format_unsupportedand so on), and the other providers' output is still returned. Timeouts and failures report their original reason and do not discard the other entries.unknownor mismatched, never assumed.binary_sessionshows the same target, provider binding and run after the call. No provider process started for the comparison survives completion or cancellation.export_evidence_bundleandimport_evidence_bundle.Expected interaction with targets
Read existing files or captured data
Target and scope details (optional)
Local native binaries that REA's existing deep providers already accept. Each requested provider runs as a local subprocess or attached engine, as
open_binaryalready does, and reads the target statically; nothing executes the target. This adds no new provider and uses no network service. Running several providers in one call raises resource use and adds provider lifecycles, so the bounds on concurrency, deadlines and cleanup need maintainer review.Verification available so far
Idea only; I need help defining checks
Verification details (optional)
Claims above were checked against REA
mainsource and docs ataeee5074d1(6.4.0). No prototype was run against real providers.Alternatives considered
compare_functionsto return both texts when providers differ. This is small, but it still needs two provider runs and a switch or a second session first, so it does not give a one-call result. It could complement this feature.provider_idtoprocedure_pseudo_codeandbatch_decompile. This is more flexible but breaks the documented one-immutable-provider session contract and is much larger.Possible direction
A provider-neutral comparison operation that opens short-lived, comparison-only provider sessions for the requested providers, separate from the bound session. It would reuse the existing pseudocode path and provider-selection rejection codes per provider, and derive one Evidence record linking the per-provider records. Concurrency (sequential or bounded) is open. Non-goals: new providers (Kuna is #1957), semantic or line-level alignment, ranking, and address normalization across builds (#1947, PRs #2124 and #2088).

Design & Architectural Boundary Notes
While comparing pseudocode across multiple decompilers (e.g. Hopper vs Ghidra vs IDA) on the same function is highly valuable for reverse engineering fidelity:
BinarySessionis designed to own exactly one active provider bridge at a time to prevent port/process contention, excessive RAM overhead (running multiple decompiler engines simultaneously), and state pollution.BinarySessioninto a multi-provider orchestrator, cross-provider comparison is best achieved at the application/workflow or agent layer:Evidencedossiers for the target function produced under each respective provider.compare_functionsor a dedicated synthesis helper over retained Evidence.@morluto commented on GitHub (Oct 30, 2026):
Real-provider follow-up on PR #8187 branch, macOS arm64, the same self-built unexecuted Mach-O, Ghidra 12.1.4 and Kuna 1.986:
open_binarywith Ghidra andanalyze_functionwith summary retained the complete_evaluatedossier. Explicitly opening the same target with Kuna and analyzing_evaluateretained a second dossier; the first reference still resolved after the switch.compare_functionsaccepted both retained references. Both providers reported the same name and0x100000430in this fixture, but REA correctly returned ambiguous function identity and all eight dimensions unknown: in particular, the providers do not establish a common coordinate commitment or stable Kuna symbol origin, and their text is not a cross-provider invariant.close_binarycleared session records, comparison by those IDs failed with actionableevidence_integrity_mismatch. Importing the bundle restored the same comparison Evidence ID. In a fresh MCP server,get_evidence_bundlesummary discovered both dossiers and twoinspect_analysis_viewnative-pseudocode pages retrieved each provider's actual text with parent references, coverage and limitations, without reopening a provider.This refines the original limitation: the current workflow can keep the observations together and recover both texts from retained or bundled Evidence, but it takes a provider switch, two analyses and separate views. A direct composition over already-retained dossiers may therefore be a smaller complementary design than always starting multiple engines; an acquisition workflow would still need separate provider lifecycles, partial failures, cancellation and preservation of the caller's existing binding. Matching names or numeric addresses alone should not be promoted into a cross-provider correspondence. The selected fixture and reported addresses do not establish other mappings or behavioral equivalence. No autonomous agent-selection or performance measurement was performed. Related: #8173.

Real cross-provider disagreement and existing manual corroboration
On current REA
a989c0e, real Ghidra 12.1.4 and Kuna 1.986 analyzed an explicitly selected, source-built x86-64 ELF containingaudit_select. The function has one unconditional write and a conditional return. Kuna rendered a second write on one return path; Ghidra rendered one. Independent instruction listing and REA's Ghidrainspect_native_instructionshow the singleMOVwrite at0x101377followed by a conditional move and return. Direct Kuna and an ordinary non-IFUNC reduction reproduce the upstream issue Kuna #1355.The existing MCP workflow can retain both observations: open Ghidra, take an
analyze_functionsummary, explicitly switch to Kuna and take its summary, then use each parent ID withinspect_analysis_viewfor pseudocode and assembly. Exporting the bundle, closing, and importing in a fresh target-free server reproduced all four normalized views exactly.compare_functionskept identity ambiguous and both text dimensions unknown; it did not attempt to flag the semantic discrepancy, consistent with its contract. The caller can manually inspect the differing pseudocode and instruction Evidence; this is not an automated verdict that one provider is correct.Coordinates matter even for the same file: the format export reported ELF value
0x1370, Kuna's entry was0x1370, and Ghidra's was0x101370. Ghidraaddress_to_file_offsetreturned0x370; independent ELF load headers map the source value to that file offset on this fixture. Kuna's assembly also included a trailing NOP outside Ghidra's displayed function body, so matching entry coordinates does not automatically establish equal extents. Those observations support a manual same-artifact handoff here, not general cross-provider correspondence.This is a concrete example for the second-opinion task and its Evidence/coordinate tradeoffs, not a request to rank outputs or assert text equality. A provider switch can retire edited session state (#8289); the test made no edits. Fixture and exported bundle hashes stayed unchanged, no target was executed, and no autonomous agent or performance trial was run.
