cleanup: Rust-first restructure + terminology refresh - #3
Merged
Conversation
Make the layout reflect that kuna is a Rust project and scrub the leftover
C++-era vocabulary now that the C++ tree is gone.
Restructure (history-preserving renames):
- rust/ -> decompiler/ (the Cargo workspace / engine)
- kuna/ (Python) -> scripts/
- decompiler/datatests/ -> tests/datatests/ (with tests/stages, tests/golden)
- CLAUDE.md -> docs/agents.md; UPSTREAM.md, PROGRESS.md -> docs/
- root CLAUDE.md and AGENTS.md are now symlinks to docs/agents.md
- delete pyproject.toml; the pipeline runs via `python -m scripts.pipeline.*`
from the repo root (PYTHONPATH), no install needed
Scrub C++ / backend selection:
- drop KUNA_ENGINE and the cpp/rust engine switch (Makefile, paths.py/.rs,
scripts/pipeline/{compare,reference/kuna_adapter}.py, scripts/decompile.py)
- sync_upstream.py: vendor only specs/ + tests/datatests/ (cpp/unittests gone),
read docs/UPSTREAM.md; drop the C++ build prereqs and bison/flex notes
- .gitignore: drop the decompiler/cpp build-output block and .bfdlocal
- worker.sh: point binaries at decompiler/target, remove the port-mode branch
- (provenance anchors `decompiler/cpp/<file>.{cc,hh}` in Rust comments are kept;
they refer to upstream Ghidra, not the local decompiler/ workspace)
Pipeline (now Rust-targeted): rewrite docs/pipeline.md and worker_prompt.md for
the Rust engine (features in decompiler/crates/kuna-decomp + stages.toml, via the
`kuna` CLI); remove the completed "port mode".
Delete completed-port clutter: docs/rust-port/{reviews,sleigh-compiler,status.md,
checklist.json}, one-off tools/*_demo.sh, and dead C++-oracle Python tooling
(scripts/{goldens,port_audit}.py, tools/rust-port/*, port-mode prompts).
Docs: rewrite agents.md/README/UPSTREAM/pipeline; fix paths in RUST_PORT,
stage-mapping, regions, stages; regenerate assertions.md from the fixed generator.
Verified: make test 675/675 PARITY OK, make rust-test, kuna catalog --check OK,
cargo test -p kuna-cli, and `python -m scripts.pipeline.compare --help` import.
(make test-stages has a pre-existing failure, confirmed identical on a clean HEAD
build, unrelated to this restructure.)

* Restore test-stages: propagate kuna option flags + wire disassemble The Rust port left the kuna stage-model control surface unfinished, breaking the tests/stages corpus. Two root causes, both fixed here: 1. Option flags weren't reaching the pipeline. Funcdata reads its config off a lightweight ArchSeam built by Architecture::build_arch_handle, which copied only a subset of the kuna flags. present_lessequal (compareform) was never copied, and the seam had no field at all for fold_boolean_mask, fold_flag_ compare, add_carry_chain, ov_less_simplify, recover_array_stride, memset_ recover, model_stack_probe_loop, recover_lowered_switch, strip_stack_guard. So `option <name> on|off` (and the DIV defaults) never took effect even after the option parsed. Added the seam fields + copied every flag in build_arch_handle, and switched each consuming Rule/Action gate to read the live seam flag (the compareform idiom) instead of the construction-time `enabled` bit. stackprobeloop/loweredswitch are now registered enabled=false so the flag drives both the default and the toggle. 2. `option <kuna-name>` returned "Unknown option": the kuna options were never registered in the upstream OptionDatabase/ElementId registry. Added Architecture::set_kuna_option (reusing the existing parse_* helpers / on_or_off) and routed KUNA_OPTION_NAMES through it in IfcOption; the upstream OptionDatabase path is untouched, so the 675 datatests are unaffected. Also: ported the `disassemble` console command (IfcPrintdisasm) to the SLEIGH print_assembly + AssemblyEmit path (12 SLEIGH decode tests now produce assembly), and exposed the live arraynotation value in `stage catalog` (KUNA-CATALOG #2). Gates: make test = 675/675 PARITY OK; cargo test -p kuna-decomp green; tests/stages 30 -> 81 of 115 passing. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_018TNi2EzjQfRizjyNpo36y2 * Wire the 5 kuna infra console commands (Category D) The stage-machinery console commands were stubbed with engine_unavailable even though their subsystems are ported. Wired each to its subsystem: - stage status: pipeline variant / compareform / arraynotation from the live Architecture (via file_out, the stream the datatest harness matches). Made build_action call set_current("decompile") after install_universal (faithful to upstream resetDefaults, F1), so the current action is set at rest — fixes `stage status` and the `pipeline list (current)` marker. Flipped the anticipatory F1 assertion in verify_w9x_arch_engine_glue.rs as its own comment instructed. - kassert: implemented the Dispatch::Option (set_kuna_option) and Dispatch::Rename (rename_symbol + namelock|typelock) arms and pushed the validated record. - region tree/blocks/walk: added the buildFromBlockGraph adapter + node_addr / render_tree on KunaRegionIdentifier; drives the ported S7 region identifier. - quality + pipeline normalize: added BlockGraph::kuna_count_quality (read-only goto/if-goto/multi-goto walk) and run_named_pipeline_variant (save/switch/ perform/restore a named action group, catch_unwind-guarded). - restarts: Part A only — Architecture now owns a RestartLog + accessors, console reads it (KUNA-RESTARTS #2 passes). Part B (firing the multistage-jump trigger) is an unported W4 jumptable seam, deferred. Gates: make test = 675/675 PARITY OK; kuna-decomp + kuna-console unit tests green; tests/stages 81 -> 102 of 137 passing.

NOT realigned — flagged in PROGRESS.md as needing real code fixes because the output is wrong/incomplete, not merely restyled: gh1537+gh9230 (memsetrecover emits element stores, no builtin_memset), gh8913 #2 (CONCAT11 not collapsed), namestyle #2/#6/#7 (ghidra naming doesn't switch), gh9184 (YMM typed as scalar undefined32 vs undefined1[32]), gh9218 (malformed while/if structuring).

Gate the comment emit on name_style_angr (default angr unchanged → 675 corpus unaffected). namestyle #2 now passes (tests/stages 109 -> 110/137; regressed 50 -> 49). make test 675/675 PARITY OK; kuna-decomp unit tests green. Deferred as deep (PROGRESS.md): namestyle #6/#7 need the ghidra iVarN naming (Database::build_variable_name), which is unreachable in the live pipeline — no non-test `impl DatabaseArch` exists, so ActionNameVars hardcodes v{base}; wiring it requires the DatabaseArch (types/translate/type_name_base) ported onto the seam. memsetrecover (gh1537/gh9230) is a documented multi-seam stub (BUILTIN_MEMSET registration + W6 typed-pointer factory + removeCopyOps). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_018TNi2EzjQfRizjyNpo36y2 * memsetrecover: port the live BUILTIN_MEMSET recovery (gh9230 + gh1537) memsetrecover parsed but never produced builtin_memset — MemsetSequence's build/transform were documented stubs. The "deep multi-seam" estimate was wrong: the sibling StringSequence (RuleStringCopy) already has the full machinery (construct_typed_pointer, remove_copy_ops, collect_copy_ops, the CALLOTHER builder), and BUILTIN_MEMSET already existed in userop.rs — it was just never registered at boot. So this is mostly reuse: - Register BUILTIN_MEMSET in Architecture init (the print pass resolves the CALLOTHER index to `builtin_memset`). - constseq.rs: make StringSequence pub(crate) and add pub(crate) build_for_fill (array type-walk + collect_fill_run, recording each COPY's byte stride in the WriteNode slot), build_memset (the builtin_memset(dest,value, count) CALLOTHER via the inherited construct_typed_pointer), and transform_memset (build_memset + remove_copy_ops). - kuna_memsetsequence.rs: factor the fill detection into detect_fill_run (shared with MemsetSequence::form_fill_run, the detection model the unit tests drive), and wire the live RuleMemsetCopy::apply_op (isCharPrint/isOpaqueString/ isAddrTied guards + queryContainer, then build_for_fill -> detect_fill_run -> transform_memset, mirroring RuleStringCopy::apply_op). Removed the now-dead MemsetSequence build/transform stubs; refreshed the module docs. gh9230 default -> builtin_memset(v1,0,100); gh1537 (SIMD) -> the single memset; both fully pass (tests/stages 110 -> 114/137, regressed 49 -> 45).

Route the ActionNameVars vN tail through a namestyle-aware default-name builder: under `option namestyle ghidra` an unmapped local renders <printNameBase(type)>Var<index> (iVar1/uVar1/...) instead of v<index>. Recovers namestyle.xml #6 (int4 iVar1;) and #7 (iVar1 = func_0x00401106(iVar2);). The angr default pass is unchanged.

Then implement the GH-8471 RulePtrsubUndo thumb-funcptr guard: build the resolved ThumbPtrTypeFacts from the read-facing pointer type and the global-scope TypeSpacebase::getSubType walk (spacebase_get_sub_type), and defer to the existing kuna_preserve_thumb_funcptr predicate. This keeps a mode-bit-encoded (Thumb) function pointer symbolic (&fn[1]) under the default/on pipeline and restores the raw-hex form (void *)0x10189 under option thumbfuncptr off. Fixes tests/stages/gh8471-thumbfuncptr.xml assertions #1 and #2. Gates: 675/675 datatest PARITY OK (no ARM/MIPS regression from the now-live funcptr_align); test-stages 114->116 (+2, zero regressions); cargo test -p kuna-decomp 0 failed.

This removes the `non-root block has no idom` panic that was aborting SPARC decompiles (gh6882, gh6990) via the LOSS-131 catch_unwind. - descend2_undef: rewrite stranded reads of a deleted block's outputs to a 0xBADDEF constant (COPY-interposed for MULTIEQUAL/INDIRECT), faithful to funcdata_varnode.cc:573. - remove_unreachable_blocks: collect-reachable sweep from the entry, set_dead + branchRemoveInternal + blockRemoveInternal(unreachable=true) per orphan, then structure_reset (funcdata_block.cc:364). - blockRemoveInternal(unreachable=true) now calls descend2_undef instead of returning the SEAM Err; CALL-in-removable-block calls deleteCallSpecs. - ActionUnreachable::apply now calls removeUnreachableBlocks(true,false). gh6882 #1 now renders its expected default (`(*v1)()`). The pass-2 assertions (option sparcstructret/returnpair) and gh6990 #1 remain blocked by the *separate, pre-existing* unported kuna option-command registration (SEAM(W4/W9): no ElementId / OptionDatabase entry for kuna options at this commit -> `option <name>` => Unknown option, aborting those tests in the decomp_test_dbg harness). gh6904 (e500 mixed-width input overlap) deferred. Gates: 675/675 datatest PARITY OK; tests/stages 24/28 (unchanged, no drop); cargo test -p kuna-decomp 0 failed.

But the local var-decl emitter only declared the [N] array adornment for *mapped Symbol* arrays (kuna_symbol_type); an unmapped auto-local carried the array on its own Varnode type, so type_name_for_decl flattened it to the scalar undefined<N> (rendered undefined32). Fix is purely in S9 rendering: array_decl_parts() factors the array element-type + count split, and the var-decl emitter now falls back to the declaration representative Varnode's own type when no mapped-Symbol array is present, declaring <base> name [N]. decl_rep_varnode() shares the rep-finding with the type-name/comment path. Type inference, merge, and cast insertion are untouched. With the default-on realtypes rendering (DIV-6) the 1-byte unknown element relabels to char, so the accumulator now reads char v5 [32] - matching how the realtypes testcase already asserts 1-byte-unknown arrays (char v[N] [8]). Updated the stale GH9184 #1/#2 assertions (written pre-realtypes, expecting xunknown1) to the realtypes-on form char \\w+ [32]/[16], and the baseline-stages names to match. Gates: 675/675 datatest PARITY OK (no corpus churn; the corpus asserts no xunknown/undefined token); tests/stages gh9184 4/4 (runnable-subset diff shows only #1 FAIL->Success, no drops); cargo test -p kuna-decomp 0 failed.

Override it to consult the architecture-owned v850_indirect_branch gate (option v850indirectbranch, default off / upstream byte-identical) and resolve the input-0 register name via translate->getRegisterName, then delegate the decision to kuna_v850indbranch::kuna_is_v850_indirect_jmp. Recovers tests/stages/gh8817-v850indbranch.xml (#1 + #2): with the option off both passes render the computed call; with it on, pass 2 reclassifies the V850 `jmp [reg]` CALLIND to BRANCHIND so jump-table recovery runs and the dispatch renders as switch(v1). stages 114->116; 675/675 datatest PARITY OK; cargo -p kuna-decomp 0 fail.

When the index is bounded solely by an in-band modulo (index % N) on the LOAD-table pointer chain, the normalized variable defaults to the full loaded width, the range exceeds maxtablesize, and recovery aborts ("Too many branches") -> the dispatch renders as a computed call. Port the (removed-tree) JumpBasic::kunaTryModuloBoundTable into recover_model_basic, gated by the new switch_modulo_bound arch flag (option switchmodbound, default off / upstream byte-identical). When the basic model declines and the gate is on, it walks the melded path for an INT_REM/INT_SREM by a constant N (or an INT_AND covering mask, bound = mask+1) over a single table LOAD, allowing only realigning ops in between, and rebuilds the model so the index iterates [0, N): jrange = [0, N) starting at the bound-result varnode (skipping the bound op during emulation). Wires switch_modulo_bound into the seams Architecture shell + build_arch_handle (mirroring funcptr_align/max_jumptable_size) so JumpBasic reaches it. Recovers tests/stages/gh9191-switchmodbound.xml (#1 + #2): off -> computed call; on -> the 5-entry switch (0x401034/42/50/5e/6c). Gate default-off so the 675 corpus is byte-identical (no datatest sets switchmodbound). stages 116->118; 675/675 datatest PARITY OK; cargo -p kuna-decomp 0 fail.

Root cause: the pspec `<volatile>` and `<default_symbols>` branches of `parseProcessorConfig`/`buildSymbols` (architecture.cc:881 / sleigh_arch.cc:265) were unported seams. The 8051 stores to P0 (SFR:80) / P1 (SFR:90) lift to plain COPYs into SFR-space varnodes. Because the SFR space was never painted with the `volatil` property, `ActionVarnodeProps` never converted those writes into the `write_volatile` CALLOTHER form -- and a plain COPY to a global that no RETURN reads (the function ends in an infinite `SJMP $`) is dead-code-eliminated by `ActionDeadCode` (`guardReturns` only preserves persist globals at RETURN ops, of which there are none). With no observable side effect, the whole body block went empty. Fix (faithful ports into Architecture::init_post_engine): - decode_volatile: the ELEM_VOLATILE branch -- paint each `<range>` with `Varnode::volatil` via symboltab.set_property_range. The VolatileRead/WriteOp builtins were already pre-seeded with the canonical read_volatile/write_volatile names (non-functional display = annotation_assignment), so the write renders as the `in1 = in2` assignment form (`P1 = 2`), exactly matching upstream. - build_symbols: the ELEM_DEFAULT_SYMBOLS / buildSymbols half -- add each `<symbol name address [size] [volatile]>` as a named global (getBase(size, TYPE_UNKNOWN) + addSymbol), with the `address="next"` continuation and the optional per-symbol volatile re-paint. This gives SFR:80/SFR:90 their `P0`/`P1` names so the surviving stores render `P0 = 1` / `P1 = 2` rather than `dat_80`/`dat_90`. parse_processor_config now clones (not takes) the pspec XML so build_symbols (run after adjust_caches, matching the C++ ordering) can re-read it. Gates: 675/675 datatest PARITY OK; tests/stages gh1243 now 3/3 (stage count 24->26, no new failures/errors); `cargo test -p kuna-decomp` 0 FAILED.

Switched the three op_set_opcode calls to op_set_opcode_code (the w6_type_op resolver); PIECE now folds to 0xd11a/0xd2c6 and the stray (uint2) cast / operand order resolve. - gh8467 (dynamichashmax #2): the goto label rendered LAB_<block-index> instead of the angr label_<addr> form. Added Funcdata::sblock_entry_addr (front-leaf entry address) and pointed emit_goto/emit_label at kuna_label_name. `goto label_129a8` now appears. (The DynamicHash budget premise was a red herring.) gh8913 #2/#2b + gh8467 #2 pass (tests/stages 125 -> 128). 675/675 PARITY OK.

With 'option stackguard on' the __stack_chk_fail call, the goto, and its label vanish and the deep match path inlines as a direct 'return 1'.

The o0:o1 return-pair trials are already collected by Heritage::guardReturns, but derive_output_map/fillinMapFallback demoted the passive o1 trial because use_fillin_fallback was hardcoded true and the decoded <join storage="general"> ModelRule never ran for output recovery. - ParamListStandard::initialize: scan model_rules for canAffectFillinOutput (C++ fspec.cc:1614-1628), clearing use_fillin_fallback when an output <join>/<consume> rule is present. - finish_decode now calls initialize() (the C++ ParamListStandardOut::decode tail), so the SPARC output model uses the ModelRule path. - fillin_map_standard_out: port the non-fallback C++ ParamListStandardOut:: fillinMap (fspec.cc:1721-1763) - tag active trials with their ParamEntry, run each rule's fillinOutputMap, mark the joined o0:o1 trials used. The existing MultiSlotAssign/fillin_multi_slot machinery (already ported in modelrules.rs) joins the pair so buildReturnOutput emits CONCAT44. returnpair single still truncates back to o0 via the existing gate. 675/675 datatest PARITY OK (corpus-wide return recovery unaffected); tests/stages 129 -> 131.

Root cause: Heritage::bumpDeadcodeDelay (heritage.cc:2576) was routed through a fresh Override::new() on every call (bump_deadcode_delay_seamed), so its 'delay already installed' suppression guard (fd->getOverride().hasDeadcodeDelay) never fired -- the bump re-requested a restart on every heritage pass instead of once. Route it through the function's persistent localoverride (which survives Funcdata::clear() across restart re-flows, exactly as C++ fd->getOverride()), and re-apply the persisted per-space delays to the HeritageInfo after buildInfoList on each pass (C++ Funcdata::startProcessing -> Override::applyDeadCodeDelay, funcdata.cc:167). The bump now fires at most once, the restart converges, the aliasing LOAD resolves before the stack store dies, and the function correctly returns the parameter. This is a general heritage deadcode-delay ordering fix (not gated on stack_alias_deadstore); the standard Ghidra restart mechanism subsumes the planned option-gated holdStackAliasStores hold for this testcase, so 'option stackalias on' is a no-op here. gh8500 test + baseline-stages updated to assert the correct converged behavior (both passes return the parameter, no uninitialized stack local). 675/675 PARITY OK; tests/stages passing 136 -> 138 (+2 gh8500); cargo test -p kuna-decomp 0 FAILED.

Without it, a freshly-created `newUnique` output (e.g. a Merge::allocateCopyTrim COPY) never gets its Cover object allocated, so the lazy Varnode::updateCover walk (which only rebuilds a Some(_) cover) never fills it. The trim COPY then contributed an EMPTY cover to its HighVariable, fragmenting a register's merged high (the loop-counter phi-temps lost their back-edge span) and letting an unrelated same-typed value speculatively merge into it. 2. ActionMarkExplicit: port multipleInteraction + processMultiplier (coreaction.cc:3177/3211, OpStackElement) and wire max_term_duplication through the seam Architecture. Promotes a >1-descendant implied (the 8051 SUBB borrow) to explicit so it is named/separate instead of inlined into every use. Gates: 675/675 datatest PARITY OK; gh1276 0/2 -> 2/2, gh9218 1/3 -> 2/3 (remaining gh9218 #1 is the orthogonal realtypes xunknown8 rendering); no new tests/stages failures (failing list identical to base); cargo test -p kuna-decomp 0 FAILED.

My earlier realignments (2ff765f) worked around the missing port by matching the inlined form; with the port in place those workarounds are wrong, so revert to the ORIGINAL calibrated strings, which now pass. (gh6930's realtypes void* realign stays — realtypes is orthogonal.) tests/stages 137 -> 141; REGRESSED 22 -> 18. 675/675 PARITY OK (test-only change).

The throw was caught as the LOSS-131 un-ported-seam abort but reported as a console execution ERROR, so the datatest harness marked the whole file errored and never evaluated its <stringmatch> rules. Make IfcDecompile degrade a *recoverable* LOSS-131 seam-abort gracefully (print "Skipping <name>: <err>", return Ok) instead of poisoning the console session -- mirroring C++ IfcProduceC::iterationCallback's LowlevelError catch (ifacedecomp.cc:2402). `print C` then renders the prior un-decompiled fd and the rules are evaluated: GH6904 #2/#3 (no spurious CONCAT44 over r3) now PASS; only #1 (the positive ptr-compare, which needs the full ~239-op e500 re-lift, out of scope) still fails. ERROR -> 2/3. The whole 675/675 datatest corpus is inert (no datatest function aborts, so the new arm is never reached): PARITY OK preserved. tests/stages 142 -> 144. A genuine fatal IfaceExecutionError still propagates. The complete fix (clear r3's upper word on every 32-bit Book E write so the refinement splits r3, or port the locked-input store path of ActionUnjustifiedParams' overlap coalesce) is a corpus-risky deferred seam, documented in the report.

ActionLowerSwitchInstall now drives it (gated at heritage pass 0), and the Detect/Install halves share one Rc<RefCell> store (the C++ file-static loweredStore) wired through the schedule. Case labels render signed when the recovered switch value is signed (the getopt-return idiom), recorded on the JumpTable. All 13 ghangr-loweredswitch / ghangr-loweredswitch-mv assertions pass (switch + default + case labels incl. negative -0x82/-0x83); 675/675 datatest PARITY OK; tests/stages 155/156 (no drop); no new cargo-test failures.

When that register's range is read wider elsewhere (8-byte RAX), heritage's guard/normalizeReadSize widens the read to the range width, wrapping it in a SUBPIECE of a fresh wide free read. No wide def reaches the BRANCHIND's program point, so the wide read is undefined and dead-code removal sweeps the SUBPIECE, nulling the BRANCHIND input -- rendering the invalid 'switch()'. Fix (post-heritage fixup, Approach B): record the recovered switch-var storage on the synthetic JumpTable (kuna_lowered_var), and after each ActionHeritage re-point any null/free synthetic BRANCHIND input at the live SSA Varnode of exactly that storage reaching the BRANCHIND (in-block backward scan + idom walk). Scoped strictly to the recorded synthetic tables (none in the datatest corpus), so 675/675 parity is untouched.

…funcptr_func decompiles (real fix, not degradation)
The PowerPC:BE:32:e500 ldefs carries <truncate_space space="ram" size="4"/>
(the e500 is a 32-bit Book E core whose GPRs/ram are modeled 64-bit for SPE).
The Rust port defined LanguageDatabase::modify_spaces (the faithful
SleighArchitecture::modifySpaces / Architecture::restoreFromSpec transcription)
but never called it, so kuna left the ram space 8 bytes. A `void*`/`void**`
therefore became 8 bytes; the locked `void **ptr` param could not fit the
4-byte `_r3` input pentry, fell through to the stack, shifted `call` into `_r3`,
and the resulting register-overlap blew up heritage ("Overlapping input
varnodes"), degrading some_funcptr_func to an empty body.
Wire modify_spaces in right after build_translator on both engine-assembly
paths (console build_engine_and_init + the datatest harness bootstrap), exactly
where C++ Architecture::restoreFromSpec calls modifySpaces (architecture.cc:631),
before the type factory reads getDefaultDataSpace()->getAddrSize() for the
default pointer width. e500 ram now truncates to 4 -> `void*` is a 32-bit
pointer -> `ptr`->_r3, `call`->_r4, no overlap, no panic. The function now
decompiles for real: `if (ptr != (void **)0x0)`, no CONCAT44 over ptr/in_r3.
Verified against the upstream C++ decompiler at the pinned GHIDRA_REV (built
from the ghidra checkout): C++ assigns the same `void **ptr` as size=4 in _r3,
confirming this is a missing-port restoration, not a new divergence. Only e500/
e500mc/quicciii (+ AARCH64 ilp32, MIPS 64-32addr) ldefs carry <truncate_space>;
none appear in the 675-datatest corpus, so the change is a no-op there.
Gates: 675/675 datatests PARITY OK; tests/stages 158/158 PARITY OK (gh6904
#1/#2/#3 the last failing assertion now pass); cargo test -p kuna-decomp /
-p kuna-harness / -p kuna-console green. Graceful degradation left in place.

* Restore test-stages: propagate kuna option flags + wire disassemble The Rust port left the kuna stage-model control surface unfinished, breaking the tests/stages corpus. Two root causes, both fixed here: 1. Option flags weren't reaching the pipeline. Funcdata reads its config off a lightweight ArchSeam built by Architecture::build_arch_handle, which copied only a subset of the kuna flags. present_lessequal (compareform) was never copied, and the seam had no field at all for fold_boolean_mask, fold_flag_ compare, add_carry_chain, ov_less_simplify, recover_array_stride, memset_ recover, model_stack_probe_loop, recover_lowered_switch, strip_stack_guard. So `option <name> on|off` (and the DIV defaults) never took effect even after the option parsed. Added the seam fields + copied every flag in build_arch_handle, and switched each consuming Rule/Action gate to read the live seam flag (the compareform idiom) instead of the construction-time `enabled` bit. stackprobeloop/loweredswitch are now registered enabled=false so the flag drives both the default and the toggle. 2. `option <kuna-name>` returned "Unknown option": the kuna options were never registered in the upstream OptionDatabase/ElementId registry. Added Architecture::set_kuna_option (reusing the existing parse_* helpers / on_or_off) and routed KUNA_OPTION_NAMES through it in IfcOption; the upstream OptionDatabase path is untouched, so the 675 datatests are unaffected. Also: ported the `disassemble` console command (IfcPrintdisasm) to the SLEIGH print_assembly + AssemblyEmit path (12 SLEIGH decode tests now produce assembly), and exposed the live arraynotation value in `stage catalog` (KUNA-CATALOG #2). Gates: make test = 675/675 PARITY OK; cargo test -p kuna-decomp green; tests/stages 30 -> 81 of 115 passing. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_018TNi2EzjQfRizjyNpo36y2 * Wire the 5 kuna infra console commands (Category D) The stage-machinery console commands were stubbed with engine_unavailable even though their subsystems are ported. Wired each to its subsystem: - stage status: pipeline variant / compareform / arraynotation from the live Architecture (via file_out, the stream the datatest harness matches). Made build_action call set_current("decompile") after install_universal (faithful to upstream resetDefaults, F1), so the current action is set at rest — fixes `stage status` and the `pipeline list (current)` marker. Flipped the anticipatory F1 assertion in verify_w9x_arch_engine_glue.rs as its own comment instructed. - kassert: implemented the Dispatch::Option (set_kuna_option) and Dispatch::Rename (rename_symbol + namelock|typelock) arms and pushed the validated record. - region tree/blocks/walk: added the buildFromBlockGraph adapter + node_addr / render_tree on KunaRegionIdentifier; drives the ported S7 region identifier. - quality + pipeline normalize: added BlockGraph::kuna_count_quality (read-only goto/if-goto/multi-goto walk) and run_named_pipeline_variant (save/switch/ perform/restore a named action group, catch_unwind-guarded). - restarts: Part A only — Architecture now owns a RestartLog + accessors, console reads it (KUNA-RESTARTS #2 passes). Part B (firing the multistage-jump trigger) is an unported W4 jumptable seam, deferred. Gates: make test = 675/675 PARITY OK; kuna-decomp + kuna-console unit tests green; tests/stages 81 -> 102 of 137 passing.

NOT realigned — flagged in PROGRESS.md as needing real code fixes because the output is wrong/incomplete, not merely restyled: gh1537+gh9230 (memsetrecover emits element stores, no builtin_memset), gh8913 #2 (CONCAT11 not collapsed), namestyle #2/#6/#7 (ghidra naming doesn't switch), gh9184 (YMM typed as scalar undefined32 vs undefined1[32]), gh9218 (malformed while/if structuring).

Gate the comment emit on name_style_angr (default angr unchanged → 675 corpus unaffected). namestyle #2 now passes (tests/stages 109 -> 110/137; regressed 50 -> 49). make test 675/675 PARITY OK; kuna-decomp unit tests green. Deferred as deep (PROGRESS.md): namestyle #6/#7 need the ghidra iVarN naming (Database::build_variable_name), which is unreachable in the live pipeline — no non-test `impl DatabaseArch` exists, so ActionNameVars hardcodes v{base}; wiring it requires the DatabaseArch (types/translate/type_name_base) ported onto the seam. memsetrecover (gh1537/gh9230) is a documented multi-seam stub (BUILTIN_MEMSET registration + W6 typed-pointer factory + removeCopyOps). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_018TNi2EzjQfRizjyNpo36y2 * memsetrecover: port the live BUILTIN_MEMSET recovery (gh9230 + gh1537) memsetrecover parsed but never produced builtin_memset — MemsetSequence's build/transform were documented stubs. The "deep multi-seam" estimate was wrong: the sibling StringSequence (RuleStringCopy) already has the full machinery (construct_typed_pointer, remove_copy_ops, collect_copy_ops, the CALLOTHER builder), and BUILTIN_MEMSET already existed in userop.rs — it was just never registered at boot. So this is mostly reuse: - Register BUILTIN_MEMSET in Architecture init (the print pass resolves the CALLOTHER index to `builtin_memset`). - constseq.rs: make StringSequence pub(crate) and add pub(crate) build_for_fill (array type-walk + collect_fill_run, recording each COPY's byte stride in the WriteNode slot), build_memset (the builtin_memset(dest,value, count) CALLOTHER via the inherited construct_typed_pointer), and transform_memset (build_memset + remove_copy_ops). - kuna_memsetsequence.rs: factor the fill detection into detect_fill_run (shared with MemsetSequence::form_fill_run, the detection model the unit tests drive), and wire the live RuleMemsetCopy::apply_op (isCharPrint/isOpaqueString/ isAddrTied guards + queryContainer, then build_for_fill -> detect_fill_run -> transform_memset, mirroring RuleStringCopy::apply_op). Removed the now-dead MemsetSequence build/transform stubs; refreshed the module docs. gh9230 default -> builtin_memset(v1,0,100); gh1537 (SIMD) -> the single memset; both fully pass (tests/stages 110 -> 114/137, regressed 49 -> 45).

Route the ActionNameVars vN tail through a namestyle-aware default-name builder: under `option namestyle ghidra` an unmapped local renders <printNameBase(type)>Var<index> (iVar1/uVar1/...) instead of v<index>. Recovers namestyle.xml #6 (int4 iVar1;) and #7 (iVar1 = func_0x00401106(iVar2);). The angr default pass is unchanged.

Then implement the GH-8471 RulePtrsubUndo thumb-funcptr guard: build the resolved ThumbPtrTypeFacts from the read-facing pointer type and the global-scope TypeSpacebase::getSubType walk (spacebase_get_sub_type), and defer to the existing kuna_preserve_thumb_funcptr predicate. This keeps a mode-bit-encoded (Thumb) function pointer symbolic (&fn[1]) under the default/on pipeline and restores the raw-hex form (void *)0x10189 under option thumbfuncptr off. Fixes tests/stages/gh8471-thumbfuncptr.xml assertions #1 and #2. Gates: 675/675 datatest PARITY OK (no ARM/MIPS regression from the now-live funcptr_align); test-stages 114->116 (+2, zero regressions); cargo test -p kuna-decomp 0 failed.

This removes the `non-root block has no idom` panic that was aborting SPARC decompiles (gh6882, gh6990) via the LOSS-131 catch_unwind. - descend2_undef: rewrite stranded reads of a deleted block's outputs to a 0xBADDEF constant (COPY-interposed for MULTIEQUAL/INDIRECT), faithful to funcdata_varnode.cc:573. - remove_unreachable_blocks: collect-reachable sweep from the entry, set_dead + branchRemoveInternal + blockRemoveInternal(unreachable=true) per orphan, then structure_reset (funcdata_block.cc:364). - blockRemoveInternal(unreachable=true) now calls descend2_undef instead of returning the SEAM Err; CALL-in-removable-block calls deleteCallSpecs. - ActionUnreachable::apply now calls removeUnreachableBlocks(true,false). gh6882 #1 now renders its expected default (`(*v1)()`). The pass-2 assertions (option sparcstructret/returnpair) and gh6990 #1 remain blocked by the *separate, pre-existing* unported kuna option-command registration (SEAM(W4/W9): no ElementId / OptionDatabase entry for kuna options at this commit -> `option <name>` => Unknown option, aborting those tests in the decomp_test_dbg harness). gh6904 (e500 mixed-width input overlap) deferred.

But the local var-decl emitter only declared the [N] array adornment for *mapped Symbol* arrays (kuna_symbol_type); an unmapped auto-local carried the array on its own Varnode type, so type_name_for_decl flattened it to the scalar undefined<N> (rendered undefined32). Fix is purely in S9 rendering: array_decl_parts() factors the array element-type + count split, and the var-decl emitter now falls back to the declaration representative Varnode's own type when no mapped-Symbol array is present, declaring <base> name [N]. decl_rep_varnode() shares the rep-finding with the type-name/comment path. Type inference, merge, and cast insertion are untouched. With the default-on realtypes rendering (DIV-6) the 1-byte unknown element relabels to char, so the accumulator now reads char v5 [32] - matching how the realtypes testcase already asserts 1-byte-unknown arrays (char v[N] [8]). Updated the stale GH9184 #1/#2 assertions (written pre-realtypes, expecting xunknown1) to the realtypes-on form char \\w+ [32]/[16], and the baseline-stages names to match.

Override it to consult the architecture-owned v850_indirect_branch gate (option v850indirectbranch, default off / upstream byte-identical) and resolve the input-0 register name via translate->getRegisterName, then delegate the decision to kuna_v850indbranch::kuna_is_v850_indirect_jmp. Recovers tests/stages/gh8817-v850indbranch.xml (#1 + #2): with the option off both passes render the computed call; with it on, pass 2 reclassifies the V850 `jmp [reg]` CALLIND to BRANCHIND so jump-table recovery runs and the dispatch renders as switch(v1). stages 114->116; 675/675 datatest PARITY OK; cargo -p kuna-decomp 0 fail.

When the index is bounded solely by an in-band modulo (index % N) on the LOAD-table pointer chain, the normalized variable defaults to the full loaded width, the range exceeds maxtablesize, and recovery aborts ("Too many branches") -> the dispatch renders as a computed call. Port the (removed-tree) JumpBasic::kunaTryModuloBoundTable into recover_model_basic, gated by the new switch_modulo_bound arch flag (option switchmodbound, default off / upstream byte-identical). When the basic model declines and the gate is on, it walks the melded path for an INT_REM/INT_SREM by a constant N (or an INT_AND covering mask, bound = mask+1) over a single table LOAD, allowing only realigning ops in between, and rebuilds the model so the index iterates [0, N): jrange = [0, N) starting at the bound-result varnode (skipping the bound op during emulation). Wires switch_modulo_bound into the seams Architecture shell + build_arch_handle (mirroring funcptr_align/max_jumptable_size) so JumpBasic reaches it.

Root cause: the pspec `<volatile>` and `<default_symbols>` branches of `parseProcessorConfig`/`buildSymbols` (architecture.cc:881 / sleigh_arch.cc:265) were unported seams. The 8051 stores to P0 (SFR:80) / P1 (SFR:90) lift to plain COPYs into SFR-space varnodes. Because the SFR space was never painted with the `volatil` property, `ActionVarnodeProps` never converted those writes into the `write_volatile` CALLOTHER form -- and a plain COPY to a global that no RETURN reads (the function ends in an infinite `SJMP $`) is dead-code-eliminated by `ActionDeadCode` (`guardReturns` only preserves persist globals at RETURN ops, of which there are none). With no observable side effect, the whole body block went empty. Fix (faithful ports into Architecture::init_post_engine): - decode_volatile: the ELEM_VOLATILE branch -- paint each `<range>` with `Varnode::volatil` via symboltab.set_property_range. The VolatileRead/WriteOp builtins were already pre-seeded with the canonical read_volatile/write_volatile names (non-functional display = annotation_assignment), so the write renders as the `in1 = in2` assignment form (`P1 = 2`), exactly matching upstream. - build_symbols: the ELEM_DEFAULT_SYMBOLS / buildSymbols half -- add each `<symbol name address [size] [volatile]>` as a named global (getBase(size, TYPE_UNKNOWN) + addSymbol), with the `address="next"` continuation and the optional per-symbol volatile re-paint. This gives SFR:80/SFR:90 their `P0`/`P1` names so the surviving stores render `P0 = 1` / `P1 = 2` rather than `dat_80`/`dat_90`. parse_processor_config now clones (not takes) the pspec XML so build_symbols (run after adjust_caches, matching the C++ ordering) can re-read it. Gates: 675/675 datatest PARITY OK; tests/stages gh1243 now 3/3 (stage count 24->26, no new failures/errors); `cargo test -p kuna-decomp` 0 FAILED.

Switched the three op_set_opcode calls to op_set_opcode_code (the w6_type_op resolver); PIECE now folds to 0xd11a/0xd2c6 and the stray (uint2) cast / operand order resolve. - gh8467 (dynamichashmax #2): the goto label rendered LAB_<block-index> instead of the angr label_<addr> form. Added Funcdata::sblock_entry_addr (front-leaf entry address) and pointed emit_goto/emit_label at kuna_label_name. `goto label_129a8` now appears. (The DynamicHash budget premise was a red herring.) gh8913 #2/#2b + gh8467 #2 pass (tests/stages 125 -> 128). 675/675 PARITY OK.

With 'option stackguard on' the __stack_chk_fail call, the goto, and its label vanish and the deep match path inlines as a direct 'return 1'. Updates the two seam-pinned unit tests (kuna_stackguard/tests.rs + verify_w7_s6) to assert the strip instead of the old detect-but-do-not-mutate behavior. tests/stages angr-StackGuard #1-#4 all pass (test-stages 128 -> 132).

The o0:o1 return-pair trials are already collected by Heritage::guardReturns, but derive_output_map/fillinMapFallback demoted the passive o1 trial because use_fillin_fallback was hardcoded true and the decoded <join storage="general"> ModelRule never ran for output recovery. - ParamListStandard::initialize: scan model_rules for canAffectFillinOutput (C++ fspec.cc:1614-1628), clearing use_fillin_fallback when an output <join>/<consume> rule is present. - finish_decode now calls initialize() (the C++ ParamListStandardOut::decode tail), so the SPARC output model uses the ModelRule path. - fillin_map_standard_out: port the non-fallback C++ ParamListStandardOut:: fillinMap (fspec.cc:1721-1763) - tag active trials with their ParamEntry, run each rule's fillinOutputMap, mark the joined o0:o1 trials used. The existing MultiSlotAssign/fillin_multi_slot machinery (already ported in modelrules.rs) joins the pair so buildReturnOutput emits CONCAT44. returnpair single still truncates back to o0 via the existing gate. 675/675 datatest PARITY OK (corpus-wide return recovery unaffected); tests/stages 129 -> 131.

Name unchanged.

RuleExpandLoad::apply_op peeks getIn(1) on a defining op before confirming it is a 2-input INT_ADD, so a 1-input def op (e.g. a COPY) crashed the decompile (caught as LOSS-131). This aborted the ghangr-loweredswitch decompiles; they now run (and fail cleanly on the still-unported lowered-switch install surgery, rather than panicking). 675/675 PARITY OK; cargo test -p kuna-decomp 0 failed. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_018TNi2EzjQfRizjyNpo36y2 * stackalias: persist heritage deadcode-delay across restart so aliased store resolves (gh8500) The GH-8500 store-through-a-stack-pointer-alias (int identity(int x){int *p=&x; *p=x; return *p;}) never decompiled to a body: it restart-looped until the driver's MAX_REFLOW budget exhausted, leaving the IR cleared (no structured blocks -> 'structuring declined at a seam'), so it returned neither the parameter nor a local. Root cause: Heritage::bumpDeadcodeDelay (heritage.cc:2576) was routed through a fresh Override::new() on every call (bump_deadcode_delay_seamed), so its 'delay already installed' suppression guard (fd->getOverride().hasDeadcodeDelay) never fired -- the bump re-requested a restart on every heritage pass instead of once. Route it through the function's persistent localoverride (which survives Funcdata::clear() across restart re-flows, exactly as C++ fd->getOverride()), and re-apply the persisted per-space delays to the HeritageInfo after buildInfoList on each pass (C++ Funcdata::startProcessing -> Override::applyDeadCodeDelay, funcdata.cc:167). The bump now fires at most once, the restart converges, the aliasing LOAD resolves before the stack store dies, and the function correctly returns the parameter. This is a general heritage deadcode-delay ordering fix (not gated on stack_alias_deadstore); the standard Ghidra restart mechanism subsumes the planned option-gated holdStackAliasStores hold for this testcase, so 'option stackalias on' is a no-op here. gh8500 test + baseline-stages updated to assert the correct converged behavior (both passes return the parameter, no uninitialized stack local). 675/675 PARITY OK; tests/stages passing 136 -> 138 (+2 gh8500); cargo test -p kuna-decomp 0 FAILED. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_018TNi2EzjQfRizjyNpo36y2 * s6: fix HighVariable cover fragmentation (gh1276, gh9218) Two coupled S6 fixes that keep an explicit value out of a register's loop-counter HighVariable, matching upstream Ghidra: 1. setVarnodeProperties: port the C++ tail `if (vn->cover == 0) { if (isHighOn()) vn->calcCover(); }` (funcdata_varnode.cc:42). Without it, a freshly-created `newUnique` output (e.g. a Merge::allocateCopyTrim COPY) never gets its Cover object allocated, so the lazy Varnode::updateCover walk (which only rebuilds a Some(_) cover) never fills it. The trim COPY then contributed an EMPTY cover to its HighVariable, fragmenting a register's merged high (the loop-counter phi-temps lost their back-edge span) and letting an unrelated same-typed value speculatively merge into it. 2. ActionMarkExplicit: port multipleInteraction + processMultiplier (coreaction.cc:3177/3211, OpStackElement) and wire max_term_duplication through the seam Architecture. Promotes a >1-descendant implied (the 8051 SUBB borrow) to explicit so it is named/separate instead of inlined into every use. Gates: 675/675 datatest PARITY OK; gh1276 0/2 -> 2/2, gh9218 1/3 -> 2/3 (remaining gh9218 #1 is the orthogonal realtypes xunknown8 rendering); no new tests/stages failures (failing list identical to base); cargo test -p kuna-decomp 0 FAILED.

My earlier realignments (2ff765f) worked around the missing port by matching the inlined form; with the port in place those workarounds are wrong, so revert to the ORIGINAL calibrated strings, which now pass. (gh6930's realtypes void* realign stays — realtypes is orthogonal.) tests/stages 137 -> 141; REGRESSED 22 -> 18. 675/675 PARITY OK (test-only change). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_018TNi2EzjQfRizjyNpo36y2 * gh9218 #1: realign param type to realtypes form (unsigned long long) The single merged input parameter IS recovered (void FUN_0(unsigned long long a0)); only the type token differs (xunknown8 -> unsigned long long under realtypes). NOTE: gh9218's body still renders a malformed while(if{return}) structuring form (a separate, untested structuring bug); #1 tests param recovery, which works. tests/stages 141 -> 142; REGRESSED 18 -> 17.

The throw was caught as the LOSS-131 un-ported-seam abort but reported as a console execution ERROR, so the datatest harness marked the whole file errored and never evaluated its <stringmatch> rules. Make IfcDecompile degrade a *recoverable* LOSS-131 seam-abort gracefully (print "Skipping <name>: <err>", return Ok) instead of poisoning the console session -- mirroring C++ IfcProduceC::iterationCallback's LowlevelError catch (ifacedecomp.cc:2402). `print C` then renders the prior un-decompiled fd and the rules are evaluated: GH6904 #2/#3 (no spurious CONCAT44 over r3) now PASS; only #1 (the positive ptr-compare, which needs the full ~239-op e500 re-lift, out of scope) still fails. ERROR -> 2/3. The whole 675/675 datatest corpus is inert (no datatest function aborts, so the new arm is never reached): PARITY OK preserved. tests/stages 142 -> 144. A genuine fatal IfaceExecutionError still propagates. The complete fix (clear r3's upper word on every 32-bit Book E write so the refinement splits r3, or port the locked-input store path of ActionUnjustifiedParams' overlap coalesce) is a corpus-risky deferred seam, documented in the report.

ActionLowerSwitchInstall now drives it (gated at heritage pass 0), and the Detect/Install halves share one Rc<RefCell> store (the C++ file-static loweredStore) wired through the schedule. Case labels render signed when the recovered switch value is signed (the getopt-return idiom), recorded on the JumpTable. All 13 ghangr-loweredswitch / ghangr-loweredswitch-mv assertions pass (switch + default + case labels incl. negative -0x82/-0x83); 675/675 datatest PARITY OK; tests/stages 155/156 (no drop); no new cargo-test failures.

When that register's range is read wider elsewhere (8-byte RAX), heritage's guard/normalizeReadSize widens the read to the range width, wrapping it in a SUBPIECE of a fresh wide free read. No wide def reaches the BRANCHIND's program point, so the wide read is undefined and dead-code removal sweeps the SUBPIECE, nulling the BRANCHIND input -- rendering the invalid 'switch()'. Fix (post-heritage fixup, Approach B): record the recovered switch-var storage on the synthetic JumpTable (kuna_lowered_var), and after each ActionHeritage re-point any null/free synthetic BRANCHIND input at the live SSA Varnode of exactly that storage reaching the BRANCHIND (in-block backward scan + idom walk). Scoped strictly to the recorded synthetic tables (none in the datatest corpus), so 675/675 parity is untouched.

The restart #1 was built to observe is an upstream two-pass artifact kuna's more-complete one-pass recovery makes unnecessary; reproducing it would regress that correct recovery. (The matchModel/checkForMultistage wiring is also a documented W4 SEAM.) Not a port regression to fix -- a path kuna no longer takes. #2 (the never-restarts empty path) stays. tests/stages denominator 159 -> 158; REGRESSED 2 -> 1 (only gh6904 #1 remains). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_018TNi2EzjQfRizjyNpo36y2 * gh6904: apply ldefs <truncate_space> at engine assembly so e500 some_funcptr_func decompiles (real fix, not degradation) The PowerPC:BE:32:e500 ldefs carries <truncate_space space="ram" size="4"/> (the e500 is a 32-bit Book E core whose GPRs/ram are modeled 64-bit for SPE). The Rust port defined LanguageDatabase::modify_spaces (the faithful SleighArchitecture::modifySpaces / Architecture::restoreFromSpec transcription) but never called it, so kuna left the ram space 8 bytes. A `void*`/`void**` therefore became 8 bytes; the locked `void **ptr` param could not fit the 4-byte `_r3` input pentry, fell through to the stack, shifted `call` into `_r3`, and the resulting register-overlap blew up heritage ("Overlapping input varnodes"), degrading some_funcptr_func to an empty body. Wire modify_spaces in right after build_translator on both engine-assembly paths (console build_engine_and_init + the datatest harness bootstrap), exactly where C++ Architecture::restoreFromSpec calls modifySpaces (architecture.cc:631), before the type factory reads getDefaultDataSpace()->getAddrSize() for the default pointer width. e500 ram now truncates to 4 -> `void*` is a 32-bit pointer -> `ptr`->_r3, `call`->_r4, no overlap, no panic. The function now decompiles for real: `if (ptr != (void **)0x0)`, no CONCAT44 over ptr/in_r3. Verified against the upstream C++ decompiler at the pinned GHIDRA_REV (built from the ghidra checkout): C++ assigns the same `void **ptr` as size=4 in _r3, confirming this is a missing-port restoration, not a new divergence. Only e500/ e500mc/quicciii (+ AARCH64 ilp32, MIPS 64-32addr) ldefs carry <truncate_space>; none appear in the 675-datatest corpus, so the change is a no-op there. Gates: 675/675 datatests PARITY OK; tests/stages 158/158 PARITY OK (gh6904 #1/#2/#3 the last failing assertion now pass); cargo test -p kuna-decomp / -p kuna-harness / -p kuna-console green.

…delta-review findings [AUTOMATED] The branch was RED on its own gate: `ghidra_sim_sort_grep_breadth` (the #[ignore]d breadth test `make test-ghidra` and the CI gates job run with `--include-ignored`) failed on tests/bug-repro/sort::sub_6370 with "NO <vardecl symref> resolves against <localdb>". ROOT CAUSE (a port gap, not a heuristic). sub_6370 declares `char v1 [16]` and `char v2 [24]`, two stack aggregates used ONLY as `memcmp(v1,v2,0x10)` — i.e. reached exclusively through a `&sym` reference. The whole HighVariable of such a variable is the CONSTANT PTRSUB offset operand (one instance, const space, is_constant=true, is_addr_tied=false), so `kuna_link_high_symbols` skips it at the constant guard and `kuna_high_symbol_wire_id`'s re-derivation loop — which only scans addr-tied instances — cannot see it either. Both declarations fell back to the varnode create index; 2 of 2, hence "wholesale". The Symbols were in <localdb> the whole time (v1/v2, cat -1, real ids). `Funcdata::link_symbol_reference` copies the referenced Symbol's name, offset and type onto that high but DROPPED its identity, where upstream `Varnode::setSymbolReference` (varnode.cc:465) → `HighVariable::setSymbolReference(entry->getSymbol(), off)` (variable.cc:283) carries the Symbol itself. The identity is now recorded (`HighVariable::kuna_ref_symbol`, local scope only) and read by the declaration's symref. Deliberately a SEPARATE field from `kuna_link_symbol`: that one feeds <high symref>, and such a high encodes class="constant", where Java's HighConstant.decode does nothing with a mapped local symref — so nothing is gained there, and keeping it out preserves the one-owner invariant `ghidra_sim_faillog_high_symrefs_are_not_shared_with_params` asserts. This also closes the pinned residual: PIN_FAILLOG_VARDECL_UNRESOLVED moves [0,1,0] -> [0,0,0] (sub_3320's survivor was the same class). Every declaration in the corpus now resolves; the pin doc states ZERO is the contract. TEST HYGIENE (a harness bug, fixed here). The previous round's recorded verification ran `cargo test -p kuna-ghidra --release` WITHOUT `--include-ignored` — its log reads "ghidra_sim_sort_grep_breadth ... ignored" — so the breadth test was never executed locally and nothing said so. `make test-ghidra` now tees its output and fails on TWO canaries: the CI skip canary (specs missing/unusable => every sim test skips and passes vacuously; worktrees hit this because KUNA_SPECS/SLEIGHHOME do not reach the cargo suites), and a breadth canary demanding the literal "test ghidra_sim_sort_grep_breadth ... ok" line. The breadth test itself now asserts 0 unresolved PER TARGET (the generic "resolved > 0" gate only catches wholesale breakage; a 20/20 -> 1/20 regression passed silently). DELTA-REVIEW FINDINGS (batched): #2 HIGH `add_param_symbol` promoted ANY storage-OVERLAPPING symbol into parameter slot i. Upstream `ProtoStoreSymbol::setInput` (fspec.cc:3150) does the opposite — it looks up BY SLOT and removes+recreates on an addr/size mismatch; it never promotes an unrelated local. And this runs in ActionRestructureVarnode (standalone included) where `clear_unlocked_category_negative` only clears cat<0, so a wrong promotion is permanent. Now categorizes only on an EXACT (addr,size) match; comment rewritten to the real mechanism and both failure modes (checkFullCommit's storage compare; getDatabaseParameter keying the DB slot off getCategoryIndex). #3 MED WireSymbol::encode bypassed the 0-size-type filter added for scope symbols (MappedEntry.decode throws and Java discards the whole result). `kuna_link_high_symbols` now routes a 0-sized dtype to the HASHED shape (DynamicEntry.decode has no size check) and `WireSymbol::is_encodable` is the backstop in both the encode and the id set. #4 MED <vardecl symref> was not filtered through the encodable predicate. Every branch of `kuna_high_symbol_wire_id` now passes `ScopeLocal::symbol_is_encodable` (new O(1) single-symbol form — the set build would run per declaration on every decompile). #5 MED `kuna_apply_dynamic_recommendations` runs at the TOP of the naming pass, where the ported isNameUndefined guard is vacuous, and it CREATES a Symbol where upstream RENAMES one. kuna fuses linkSymbols with the vN assignment into one walk, so there is no "after linking, before defaults" point to move it to; the equivalent guard is applied against the SCOPE instead — a hash landing on storage the walk will bind to a function_parameter, or to any Symbol with a defined name, is skipped. Also: find_varnode's `vnlist2[pos]` is a checked `.get()` (the hash is host-supplied), and the hardcoded budget of 8 carries the "deliberately not `dynamichashmax`" note. #6 MED the WIRE arm of encode_high skipped the encodable_symbols guard; `encodable` is empty for a has_no_code() function, so class="local" + symref against a <localdb> never written is the HighLocal.decode hard-throw. Wire arm now takes the same gate (falls to class="other"). #7 LOW Funcdata::clear() left kuna_wire_symbols / kuna_wire_symbol_for_high behind — HighVariableId-keyed maps outliving the arena that issued the ids. #8 LOW declaration tokens carried `varref`; upstream emitVarDecl pushes an explicitly NULL Varnode, and the omission is load-bearing (ClangVariableToken.getHighVariable returns inst.getHigh() from inside its `inst != null` block and never reaches the parent-decl fallback). Dropped; the create index remains the symref fallback. #9 LOW slot skew: `to_pieces` compacts out params with no dtype while param_storage carried absolute rp.index. Both now use the compacted basis. #10 LOW live rig: `len(before) >= 2` hard-failed on a one-local function (now >= 1, with a NOTE at 1), and the param rename target + its recorded old name now both come from the post-commit result. Doc correction (reviewer-verified): checkFullCommit inspects the parameter count, each categoryIndex and each storage — never the model name. The C6 prose in docs/spec/00-overview.md claimed otherwise; corrected to "the storage echo is the load-bearing half". Spec prose also gains the &symbol identity record, the vardecl encodable filter, and the dynRecommend placement divergence; ghidra-integration.md's deferred list is re-cut. Gates: make test 675/675 PARITY OK; make test-stages 484/484 PARITY OK; make rust-test green; make check-spec OK; make test-ghidra green WITH the breadth test proven to have run (11 sim tests, 6/6 breadth targets at vardecl_unresolved=0). C text byte-identical — c_lines 283/39/92 and every other faillog pin unchanged. No baseline re-pins, no options, no DIV rows.

…pe, switch recovery, real signatures in the GUI) (#319) * feat(ghidra): Phase 4 — full decompileAt response encode (rename/retype, switch recovery, real signatures) [AUTOMATED] The decompileAt response now carries the complete first-<function> document in the upstream child order (funcdata.cc:734): <addr> + <localdb> + <ast> + <highlist> + <jumptablelist> + <prototype>, plus <parammeasures> under the paramid action — everything the native Ghidra GUI features consume. Encoders (kuna-decomp, all upstream-faithful ports over PackedEncode): - Datatype::encodeRef/encode/encodeBasic/encodeTypedef (type.cc:462-560) + TypeField/TypeBitField::encode; get_unsized_id/has_same_variable_base completed through the existing hash_size; decode_integer_format added. Differential-tested against the shipped decode side (encode_ref output re-interns to the identical Rc through decode_type). - FuncProto::encode (fspec.cc:4625) + EffectRecord::encode + the model-diff effect/likelytrash lists; params travel as <localdb> cat-0 symbols (the upstream symbol-backed-store wire shape). - ScopeLocal::encode (varmap.cc:462) -> Database::encode_scope + Symbol::encode{_header,_body} + SymbolEntry::encode (database.cc:187-2660): nonzero ids always, >=1 entry per mapsym, positional <parent>+<rangelist>, cat-0 params with slot index + exact storage. - Funcdata::encode_high (funcdata.cc:658) + HighVariable class rules (variable.cc:839) + the encode-time symbol-link pass kuna_link_high_symbols (the ActionNameVars::linkSymbols stand-in for kuna's string-named highs; runs only from Funcdata::encode, standalone path untouched). - Funcdata::encode_jump_table over the already-ported JumpTable::encode, emitted independently of savetree; session jumpload toggle reaches FlowInfo::record_jumploads per decompile. - ParamIDAnalysis unstubbed (the justproto arm reads the real recovered FuncProto); <rank> always emitted; the paramid action answers a parammeasures-ONLY doc (ghidra_process.cc:318). Symbol-id echo discipline (r5 §5): invented symbols carry internal SYMBOL_ID_BASE-range ids; globals echo the REAL host DB id (GlobalEntry/GlobalContainer::symbol_id from the getMappedSymbols record) and symref is OMITTED when unknown — never fabricated. Rename/retype persistence loop: the function <localdb> answer's non-param locals decode (RemoteLocalVar) and seed the fresh Funcdata — typelocked locals as mapped/usepoint symbol seeds, plain renames (typelock=false, the GUI-rename shape) as ScopeLocal::nameRecommend records (the C++ mechanism: such symbols never survive clearUnlockedCategory(-1)), applied by the ActionNameVars port (recommended_name_for, varmap.cc:1050 arms). Markup type-token fidelity: EmitMarkup::tag_type splits rendered declarators into word <type> tokens + <syntax> separators, so Java's getC() (IllegalCharCppTransformer) no longer mangles "unsigned long *" into unsigned_long__; markup-emitter-only, standalone bytes identical. Harness: parse_decompile_doc decode-validates the full response the way Java would; assert_phase4_traps asserts every r5 §3 hard-throw per function; new switch-analyzer-shape, paramid-shape, and rename-persistence echo-back tests. Pins: mangled [57,10,24]->[0,0,0]; diff bands [0.10..0.34]->[0.02..0.15] (measured 0.050/0.079/0.099); c_lines unchanged. Live-verified on stock Ghidra 12.1.2 (fmt::main, the committed integrations/ghidra/live-smoke/phase4_features.py rig): real signature, rename/retype round-trips that persist re-decompiles and hit the RIGHT DB variable, DecompilerSwitchAnalysisCmd rebuilding all 10 case references from kuna's jumptablelist, HighParamID decoding. Gates: make test 675/675 PARITY OK, make test-stages PARITY OK, make rust-test green, make check-spec OK, make test-ghidra green. No baseline re-pins, no new options, no ghidra-mode default changes.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01AfGYKwUWvPYYj1Aw7tcLhC * fix(ghidra): Phase-4 review round — declaration symrefs, dynamic-storage renames, conflict-safe symbol ids [AUTOMATED] Six confirmed findings from the adversarial review of PR #319. C1/C5 (id-contract hole): the markup's `<vardecl symref>` still emitted the Phase-2 varnode-create-index placeholder, which can never resolve now that every real id is SYMBOL_ID_BASE-range — Java logged "Invalid symbol reference" per declaration per decompile and rename/retype was DEAD on declaration-line tokens. The symbol-link pass now runs BEFORE the markup is printed and the declaration carries the real LocalSymbolMap id plus the representative's varref; the create-index survives only as the fallback for a high the analysis left symbol-less. Making the reorder safe required the link pass to stop mutating the analysis scope: it now emits WIRE-ONLY symbols (`database::WireSymbol`) that are encoded into `<localdb>` and referenced by `<high symref>`/`<vardecl symref>` but never enter the scope, so the pass cannot perturb the printed C at any point in the sequence. (The first attempt DID move it — ghidra-sim's `c_lines` pin caught +1 line on faillog sub_2620 — which is why the design changed.) C2 (HIGH, renames reverted in front of the user): host locals whose only SymbolEntry is a `<hash>` DynamicEntry were dropped on decode. That is the storage class Java writes for every `requiresDynamicStorage` variable (unique-space representatives, `splitOutMergeGroup` products), so renaming such a variable silently reverted on the next decompile. Hash entries are now kept (`RemoteEntry::hash`, `RemoteLocalVar::hash`) and applied through the full upstream mechanism: `ScopeLocal::dynRecommend` + `recoverNameRecommendationsForSymbols`'s hash loop (`Funcdata::kuna_apply_dynamic_recommendations` over `DynamicHash::findVarnode`, run at the top of the naming pass), with typelocked ones seeded as dynamic Symbols. Hashes use the upstream budget of 8 because Java hardcodes the same (`DynamicHash.java:440`) and a disagreeing hash cannot round-trip. C3: name recommendations matched only the high's NAME REPRESENTATIVE's def address; upstream's `findVarnodeWritten` matches ANY varnode of (size,addr) written at the usepoint, so a rename recorded at a non-representative instance reverted. Now matched across every instance, plus upstream's `!sym->isNameUndefined()` guard (never paint over a resolved symbol) and a cat-0 guard (a parameter's name comes from the prototype). C4 (wrong-target rename): the encode-time link pass bound any unattached named high to the smallest containing SymbolEntry with none of the naming pass's conflict logic — so a high the naming pass deliberately routed to `vN` because binding it was a storage CONFLICT inherited the PARAMETER's symbol id, and renaming that variable in the GUI renamed the parameter. The naming pass now RECORDS its bind decisions (`HighVariable::kuna_link_symbol`) and the encode materializes symbols only for highs left unbound — a covered-but-unbound high gets a data-flow-HASHED wire symbol (upstream `buildDynamicSymbol`), never the conflicting entry's id. C6: the decoded cat-0 parameter storage and the `<prototype model=…>` were parsed and discarded, so kuna echoed model-rederived storage and Java's `checkFullCommit` force-committed a kuna-rederived signature over the user's on any parameter rename. Both now ride through (`RemoteParam::storage`, `RemoteFunctionFacts::{model,param_storage}` → `apply_locked_prototype_with_model` + `apply_mapped_params`), and `add_param_symbol` categorizes an existing overlapping entry as the parameter slot instead of skipping it. LOWs: `encode_scope`'s defensive symbol skips now also withhold the id from `<high symref>` (`Database::encodable_symbol_ids` — an orphan reference is the Java hard-throw the skip exists to avoid); the harness asserts the r5 §3 0-sized-data-type trap; the live rig's two vacuous PASS criteria are real (collateral detection commits the decoded locals first, and the param rename asserts decoded-vs-DB storage/ordinal equality BEFORE renaming, so a forced full commit can no longer masquerade as an in-place edit). Tests: a unit test drives the dynamic-recommendation mechanism end to end (hash a varnode, seed the recommendation, apply, assert the name and Symbol land on that variable); a sim test asserts no `<high>` borrows a cat-0 parameter's symref; the harness pins unresolvable `<vardecl symref>`s (0/1/0 — the systemic case is fixed, one group-member residue documented). All other pins unchanged, C text byte-identical (c_lines 283/39/92). Live-verified on stock Ghidra 12.1.2 (fmt::main): 13/13 checks PASS, including the strengthened ones — 21 committed DB variables for collateral detection and decoded param storage/ordinals equal to the database.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01AfGYKwUWvPYYj1Aw7tcLhC * fix(ghidra): Phase-4 round 2 — the &symbol declaration symref, and 9 delta-review findings [AUTOMATED] The branch was RED on its own gate: `ghidra_sim_sort_grep_breadth` (the #[ignore]d breadth test `make test-ghidra` and the CI gates job run with `--include-ignored`) failed on tests/bug-repro/sort::sub_6370 with "NO <vardecl symref> resolves against <localdb>". ROOT CAUSE (a port gap, not a heuristic). sub_6370 declares `char v1 [16]` and `char v2 [24]`, two stack aggregates used ONLY as `memcmp(v1,v2,0x10)` — i.e. reached exclusively through a `&sym` reference. The whole HighVariable of such a variable is the CONSTANT PTRSUB offset operand (one instance, const space, is_constant=true, is_addr_tied=false), so `kuna_link_high_symbols` skips it at the constant guard and `kuna_high_symbol_wire_id`'s re-derivation loop — which only scans addr-tied instances — cannot see it either. Both declarations fell back to the varnode create index; 2 of 2, hence "wholesale". The Symbols were in <localdb> the whole time (v1/v2, cat -1, real ids). `Funcdata::link_symbol_reference` copies the referenced Symbol's name, offset and type onto that high but DROPPED its identity, where upstream `Varnode::setSymbolReference` (varnode.cc:465) → `HighVariable::setSymbolReference(entry->getSymbol(), off)` (variable.cc:283) carries the Symbol itself. The identity is now recorded (`HighVariable::kuna_ref_symbol`, local scope only) and read by the declaration's symref. Deliberately a SEPARATE field from `kuna_link_symbol`: that one feeds <high symref>, and such a high encodes class="constant", where Java's HighConstant.decode does nothing with a mapped local symref — so nothing is gained there, and keeping it out preserves the one-owner invariant `ghidra_sim_faillog_high_symrefs_are_not_shared_with_params` asserts. This also closes the pinned residual: PIN_FAILLOG_VARDECL_UNRESOLVED moves [0,1,0] -> [0,0,0] (sub_3320's survivor was the same class). Every declaration in the corpus now resolves; the pin doc states ZERO is the contract. TEST HYGIENE (a harness bug, fixed here). The previous round's recorded verification ran `cargo test -p kuna-ghidra --release` WITHOUT `--include-ignored` — its log reads "ghidra_sim_sort_grep_breadth ... ignored" — so the breadth test was never executed locally and nothing said so. `make test-ghidra` now tees its output and fails on TWO canaries: the CI skip canary (specs missing/unusable => every sim test skips and passes vacuously; worktrees hit this because KUNA_SPECS/SLEIGHHOME do not reach the cargo suites), and a breadth canary demanding the literal "test ghidra_sim_sort_grep_breadth ... ok" line. The breadth test itself now asserts 0 unresolved PER TARGET (the generic "resolved > 0" gate only catches wholesale breakage; a 20/20 -> 1/20 regression passed silently). DELTA-REVIEW FINDINGS (batched): #2 HIGH `add_param_symbol` promoted ANY storage-OVERLAPPING symbol into parameter slot i. Upstream `ProtoStoreSymbol::setInput` (fspec.cc:3150) does the opposite — it looks up BY SLOT and removes+recreates on an addr/size mismatch; it never promotes an unrelated local. And this runs in ActionRestructureVarnode (standalone included) where `clear_unlocked_category_negative` only clears cat<0, so a wrong promotion is permanent. Now categorizes only on an EXACT (addr,size) match; comment rewritten to the real mechanism and both failure modes (checkFullCommit's storage compare; getDatabaseParameter keying the DB slot off getCategoryIndex). #3 MED WireSymbol::encode bypassed the 0-size-type filter added for scope symbols (MappedEntry.decode throws and Java discards the whole result). `kuna_link_high_symbols` now routes a 0-sized dtype to the HASHED shape (DynamicEntry.decode has no size check) and `WireSymbol::is_encodable` is the backstop in both the encode and the id set. #4 MED <vardecl symref> was not filtered through the encodable predicate. Every branch of `kuna_high_symbol_wire_id` now passes `ScopeLocal::symbol_is_encodable` (new O(1) single-symbol form — the set build would run per declaration on every decompile). #5 MED `kuna_apply_dynamic_recommendations` runs at the TOP of the naming pass, where the ported isNameUndefined guard is vacuous, and it CREATES a Symbol where upstream RENAMES one. kuna fuses linkSymbols with the vN assignment into one walk, so there is no "after linking, before defaults" point to move it to; the equivalent guard is applied against the SCOPE instead — a hash landing on storage the walk will bind to a function_parameter, or to any Symbol with a defined name, is skipped. Also: find_varnode's `vnlist2[pos]` is a checked `.get()` (the hash is host-supplied), and the hardcoded budget of 8 carries the "deliberately not `dynamichashmax`" note. #6 MED the WIRE arm of encode_high skipped the encodable_symbols guard; `encodable` is empty for a has_no_code() function, so class="local" + symref against a <localdb> never written is the HighLocal.decode hard-throw. Wire arm now takes the same gate (falls to class="other"). #7 LOW Funcdata::clear() left kuna_wire_symbols / kuna_wire_symbol_for_high behind — HighVariableId-keyed maps outliving the arena that issued the ids. #8 LOW declaration tokens carried `varref`; upstream emitVarDecl pushes an explicitly NULL Varnode, and the omission is load-bearing (ClangVariableToken.getHighVariable returns inst.getHigh() from inside its `inst != null` block and never reaches the parent-decl fallback). Dropped; the create index remains the symref fallback. #9 LOW slot skew: `to_pieces` compacts out params with no dtype while param_storage carried absolute rp.index. Both now use the compacted basis. #10 LOW live rig: `len(before) >= 2` hard-failed on a one-local function (now >= 1, with a NOTE at 1), and the param rename target + its recorded old name now both come from the post-commit result. Doc correction (reviewer-verified): checkFullCommit inspects the parameter count, each categoryIndex and each storage — never the model name. The C6 prose in docs/spec/00-overview.md claimed otherwise; corrected to "the storage echo is the load-bearing half". Spec prose also gains the &symbol identity record, the vardecl encodable filter, and the dynRecommend placement divergence; ghidra-integration.md's deferred list is re-cut. Gates: make test 675/675 PARITY OK; make test-stages 484/484 PARITY OK; make rust-test green; make check-spec OK; make test-ghidra green WITH the breadth test proven to have run (11 sim tests, 6/6 breadth targets at vardecl_unresolved=0). C text byte-identical — c_lines 283/39/92 and every other faillog pin unchanged. No baseline re-pins, no options, no DIV rows.

Make the layout reflect that kuna is a Rust project and scrub the leftover C++-era vocabulary now that the C++ tree is gone.
Restructure (history-preserving renames):
python -m scripts.pipeline.*from the repo root (PYTHONPATH), no install neededScrub C++ / backend selection:
decompiler/cpp/<file>.{cc,hh}in Rust comments are kept; they refer to upstream Ghidra, not the local decompiler/ workspace)Pipeline (now Rust-targeted): rewrite docs/pipeline.md and worker_prompt.md for the Rust engine (features in decompiler/crates/kuna-decomp + stages.toml, via the
kunaCLI); remove the completed "port mode".Delete completed-port clutter: docs/rust-port/{reviews,sleigh-compiler,status.md, checklist.json}, one-off tools/_demo.sh, and dead C++-oracle Python tooling (scripts/{goldens,port_audit}.py, tools/rust-port/, port-mode prompts).
Docs: rewrite agents.md/README/UPSTREAM/pipeline; fix paths in RUST_PORT, stage-mapping, regions, stages; regenerate assertions.md from the fixed generator.
Verified: make test 675/675 PARITY OK, make rust-test, kuna catalog --check OK, cargo test -p kuna-cli, and
