`ruff_cpp_spo`'s body arm existed as an unwired draft: the fingerprint the fuzzy recipe codebook classifies on (`writes`/`reads`/`raises`/`calls` plus the J1 `guarded_writes` guard) was computed by `method_body_arm` and then thrown away, because nothing on `CppMethod` could carry it and no expand arm could emit it. C++ was the one frontend whose bodies produced no facts. Wire it end to end, and correct the draft against measured libclang shapes. The draft had three defects, each found by dumping real cursors rather than reading the AST docs: * libclang exposes no binary-operator kind, so the draft recorded the LHS of ANY binary operator as a write — `if (status_ == v)` reported a mutation. The operator is now read off the token stream. * the assignment target also landed in `reads`, so a pure setter classified as `Normalize` instead of `Compute`. * `guarded_writes` was never populated, so the J1 split the codebook needs could not fire on C++ at all. Two shapes the draft could not have known without measuring: a class-typed member assigns through `operator=`, so it arrives as a `CallExpr` and not a `BinaryOperator`; and a call's own callee reference is a `MemberRefExpr` that would otherwise be recorded as a read of a field named after the method. Also: * `walk_tu` now parses bodies; `walk_tu_configured` opts out for a signature-only walk, and takes a `BodyArmConfig` so a corpus can supply its own mutator vocabulary instead of the shipped closed set. * the arm is harvested from `get_definition()`, and `walk_files` merges arms across translation units — without both, every out-of-line definition (most of the behaviour in a real C++ corpus) harvests nothing. * `recipe::classify` is generic over a new `BodyFacts` trait implemented for both `Function` and `CppMethod`. Its docs already claimed it classified C++ methods; its signature accepted only `Function`, so it could not. * `CppMethod` joins the DTO-surface lock as `CPP_METHOD_DTO`, pinned against `FUNCTION_DTO` so the two frontends cannot drift apart silently. Every guard is disable-verified red-then-green (16 checks). Two of those runs came back green and were investigated rather than accepted: one was a mis-aimed disable, the other a genuinely vacuous fixture — the header in the cross-TU test parsed as C, not C++, so the two-sighting condition it measures never occurred and the assertions held with the merge removed. That fixture now passes `-x c++` and asserts up front that the header's own sighting is arm-less.

Each was true when written and is not now: * "the 13 C++ predicates" — a count in prose goes stale the first time a predicate is minted, and is then cited as evidence. Replaced with a pointer to the test that actually asserts the set. * "`extract` ... remains `todo!()` (per-TU include resolution + cross-TU dedup)" — the tree walk and the cross-TU dedup ship as `extract_dir` / `extract_tree`. Only per-TU include auto-detection is missing, which is the whole of what `extract` would add. * "behind a `libclang` feature, when wired" — it is wired. * `predicate_count_locked_at_47` names a gate that does not exist; the gate is `predicate_count_locked_at_79` in `triple.rs`. A reader grepping for the old name found nothing. The last one now says the number moves with the vocabulary and the gate is the test, so the reference cannot rot the same way again.

`if_stmt` decides a guard per branch, and two of its outcomes had no test: an enclosing absence guard crossing a nested `if` that has no guard of its own (the write is still only reachable when the member was absent), and that same guard being dropped by a nested `if` that guards on a different member. Both halves are disable-verified. Threading `None` instead of the enclosing guard fails the first; letting `record_write` accept any guard rather than one naming the written member fails the second, and takes the existing other-member case down with it.

The codebook's coverage table had listed `ruff_cpp_spo` as scaffolded since 2026-07-06, and its "a frontend adds the arm by populating those Vecs — zero IR change" line was true only for the three frontends that route methods through `Function` itself. C++ has its own method struct, so wiring its arm cost a real (additive) IR change plus a trait, and the doc now says so. The probe plan gains a dated entry stating what is measured, what is not, and the next probe. Three of its claims are corrected here against facts the entry was written without: * it named a test (`provenance_tiers_match_ruby_reference`) that does not exist; the extended test is `cpp_truth_tiers_match_calibration`. * it said the feature had zero corpus-scale numbers. A one-off census has since been run and is recorded, with the finding that the same corpus parsed under C++17 rather than C++20 loses a third of its body facts to silently dropped declarations — the exact partial-AST failure the walker's own diagnostics warn about, reproducing on a real tree. * it flagged one of the two green disable runs as unidentifiable. It was the signature-only opt-out, which is enforced by two independent mechanisms, so no single disable can turn it red. `guarded_writes` reads 0 on that corpus and the entry says why: the whole tree holds three absence tests on a member and none of them is a write. That is a statement about the corpus, not about the detector. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011JRoXmYPrE8KubXVrDB71L
The example predated the body arm and reported only the signature plane, so the one capability that had no corpus-scale numbers also had no way to produce them. It now prints the five fact totals, a `RecipeCentroid` census via `recipe::classify` (every variant including the zeroes), and a top-classes-by- body-fact list — the same shape of numbers the Ruby and C# legs already report. Two things the doc header now states rather than leaving a reader to infer: * it walks headers only, so most bodies are inline accessors and a low non-`Empty` fraction is the example's scope, not a harvest gap. * `guarded_writes` reads 0 on this corpus because the whole tree holds three absence tests on a member and none is a lazy-init write. That is the corpus, not the detector. The clang args move to `-std=c++20`, which this corpus needs: under c++17, `common/assert.h` fails on `std::format` and libclang recovers by silently dropping the declarations after it, measured at roughly a third of the body facts (13.0% against 20.7% of methods reaching a non-`Empty` centroid). That is the partial-AST failure the example's own diagnostic warning exists to catch, so it should not have been walking into it. Run on `src/include/catalog`: 2424 methods, 381 with at least one body fact, census `Observe=283 Compute=62 Normalize=19 Cascade=10 Guard=7`. The 381 agrees exactly with an independent count of body-predicate subjects in the emitted ndjson. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011JRoXmYPrE8KubXVrDB71L
Both docs said the corpus census was a one-off that nothing re-runs. The harvest example now prints it, so that is no longer the limit. The limit that remains is narrower and worth stating precisely: the example prints and does not assert, so a regression would appear in the output and fail nothing. Records the header-only numbers and the cross-check that makes them worth trusting — the 381 methods carrying a body fact agree exactly with an independent count of body-predicate subjects in the emitted ndjson.

Checking the Python row while correcting the C++ one turned up the same defect. The table said `ruff_python_spo` had "reads/raises only" and needed writes, calls and helpers. It has had all of them for some time: `functions.rs`'s `BodyWalker` populates every fact set, including the J1 guard across three spellings and `calls` over a closed mutator set with a receiver label, and `dto_arm_writes_guarded_writes_and_calls` asserts them end-to-end with a negative case for a local assignment. The crate's own `lib.rs` quotes this very row as the thing it was closing, so the table has been contradicted from inside the repo and nothing noticed. Also names what the `helpers` column means, because it did not mean the same thing in every row. For Ruby it is a real capability — private defs live in a separate pool and would otherwise be dropped, which is the hook loss this document opens with. Python has no visibility keyword and C++ keeps every method in one collection with its own access field, so neither has a subset to split off. Those two rows now read n/a rather than a cross, which was inviting the reading that a frontend was losing hooks when it was not.

The crate description and module doc both said the Python frontend was `ruff_python_dto_check` and that a Ruby one was future work. Neither holds. `ruff_python_dto_check` does not depend on this crate, never builds a `ModelGraph`, and emits its own JSON bundle schema — it is a separate harvester, not this crate's Python frontend. The real one is `ruff_python_spo`, whose own module doc says so. `ruff_ruby_spo` is not future either; the recipe codebook calls it the reference frontend. Names the four that fill the IR directly (Odoo, Rails, Flask-SQLAlchemy, C++) and explains why the fifth does not: Roslyn is .NET-only, so `ruff_csharp_spo` parses out of process and joins at the ndjson contract instead. That is why it references no `ModelGraph` — previously readable as a gap rather than a design. The old claim is left in the doc as a note rather than deleted, because a reader who followed it once should be able to see it was corrected and why. The description is crate metadata, so it was wrong in the place least likely to be checked and most likely to be published.

Review finding, verified before fixing. A class may declare `value() &` and `value() &&`. They agree on name, parameter types and cv-qualifier, so the method IRI could not tell them apart and both collapsed onto one node under the `(s, p, o)` dedup. A probe confirmed it: two ref-qualified overloads with different writes produced one subject carrying both. The body arm is what made that harmful rather than merely untidy. Before it, colliding overloads shared signature triples; now they would share each other's writes and calls, and `merge_body_arms` would copy whichever definition it reached first onto both. `CppMethod` gains a `ref_qualifier`, populated from libclang, carried in the IRI suffix beside the cv-qualifier, recovered in reassembly by reading that suffix, and matched in the merge key. Reassembly parses it from the IRI rather than a new predicate, because the IRI already carries it unambiguously and minting one would be an ontology change for a fact that is not missing. Three guards, each disable-verified red-then-green: dropping it from the IRI, from the merge key, and from what the walker reads. The last needs a real parse to be meaningful, since a hand-built fixture cannot tell a populated field from one that is always empty. Two more findings from the same review: * the harvest example recursed with `Path::is_dir`, which follows symlinks, so a directory symlink to an ancestor loops forever. The crate's own `collect_cpp_files` already guards this with `DirEntry::file_type`, for the same reason, so the example had reintroduced a solved bug. Fixed the same way. It carries no test, because an example is not a test target; the crate's equivalent is covered by `extract_tree_skips_directory_symlink_cycles`. * the codebook said the fingerprint is four fact sets while the table beneath it listed five. Not cosmetic: `classify` tests `guarded_writes` before `Compute` and `Normalize`, so a frontend trusting the sentence over the table would misclassify every guarded default.

Compare
The body arm ends by collapsing its traversal into sets: `method_body_arm`
runs `facts.sort(); facts.dedup();` over all five vectors, unconditionally.
And `walk_body` gives `ForStmt` / `WhileStmt` / `DoStmt` / range-`for` /
`SwitchStmt` / `TryStmt` / `LambdaExpr` no match arm at all — their contents
are visited, their boundaries recorded nowhere. So a write inside a loop, two
writes in a row, and a call in an else-branch are all unrepresentable, and the
recurring shapes a behavioral vocabulary would be made of are exactly the ones
that need order and scope.
That is right for `recipe::classify`, which is a set-membership classifier by
design. It is wrong as the only thing the walker emits.
`events` is a second walk over the same cursor that preserves three things
separately: identity in a deduped symbol table, order in an event stream that
is never sorted, structure in a scope tree. The same fact occurring twice is
two events pointing at one symbol.
Additive: `method_body_arm`, `BodyArm`, `CppMethod`, `expand` and the emitted
ndjson are unchanged, and `harvest_ladybug` over `catalog` reproduces its
2,106,907 bytes byte-identically. `events_collapse_to_the_shipped_five_sets`
asserts the two walkers agree on what a fact IS, so the difference is only
what is preserved about it. The shipped arm runs on the same cursor in the
same parse and its verdict rides in `methods.tsv`, so a consumer can compare
without a second walk making the difference ambiguous.
The alphabet is 20 primitive kinds. There is deliberately no RAII, iterator-
loop, virtual-dispatch or move kind: those are candidate learned tokens, and
emitting them would write a downstream tokenizer's answer into its input.
Identities are verbatim, never hashed. libclang exposes no CFG, so `control`
carries only structurally-certain relations and every event keeps its source
byte anchor — lexical order stays checkable against traversal order instead of
being silently conflated with it.
Three defects the control fixture caught, whose expected sequence was written
before the code existed:
- a call's own callee is a `MemberRefExpr`, so walking it emitted a read of a
member that does not exist — the exact trap the shipped walker documents;
- braced arms opened a redundant `Block`, which would have taught a tokenizer
brace style rather than behavior;
- `do { } while (c)` puts its body FIRST, so the "last child is the body" rule
walked the condition as a statement and wrapped the real body in a Block.
Where libclang disagreed with the hand-written expectation — the `for` header
emits its condition marker after init/cond/inc, which is not source order —
the disagreement is recorded rather than reconciled.

`virtually_overrides` is the one statement of behavioral relatedness the compiler makes for free, and a retrieval measure needs the PAIR. A boolean says a method overrides something without saying what, so any consumer comparing representations by distance had nothing to score against. `methods.tsv` gains a nineteenth column holding the base overload's IRI in the same per-overload form as the subject, so the two join directly. Also two clippy nits from the pedantic set: `map_or(false, ..)` becomes `is_some_and`, and the collapse test's `as u32` casts become `try_from`.

The `typos` hook read `Parm` inside `EntityKind::ParmDecl` as a misspelling of `Param`. The identifier is libclang's own cursor-kind name, surfaced by the `clang` crate, so "correcting" it does not compile. Allowlisted as a whole identifier rather than as the bare word `Parm`, so a genuine `Parm`-for-`Param` typo elsewhere is still caught.

The plan carried the defect and the control-fixture figure. On the 227-TU ladybug corpus the number is much worse: the shipped set arm retains 2.7% of ordered events, no adjacency and no scope structure, where the fixture suggested 11.2%. The gap is call sites. Also records what the loss costs in bits, and the decomposition that corrects the earlier framing: order and alphabet each buy roughly half, so restoring order alone would not have closed it.

The range-for scope test panicked "missing RangeFor" on macOS while passing on Linux. Its fixture included <vector> and ranged over a std::vector; macOS CI runs libclang without a sysroot, so the include failed, the parameter got an error type and the range-for never parsed. The other three loops in the same fixture need no header, which is why only RangeFor went missing. The fixture now ranges over a built-in array and needs no standard library at all. Reproduced locally by parsing both fixtures with -nostdinc++: the old one yields For/Function, the new one yields For/Function/RangeFor. Four findings from review, each verified against current code first: - A delete-expression's own type is void, so every Delete event was labelled void. The deleted type comes from the operand with one pointer layer removed. New is unaffected, since its own type is the allocated pointer type. - The compilation-database reader only understood "command". An entry using "arguments" left its file pending and the next entry's command was attributed to it, so that file was dropped and another could be given the wrong flags. Entries are now parsed independently and flushed at their closing brace, both command forms are read, and an entry carrying neither is reported. - The overridden-base IRI reached methods.tsv without the tab and newline guard every other cell goes through. - The "has a body" metric counted parameter events, so a method with parameters and an empty body was reported as having one. Also moved two test fixture writes inside the libclang lock. Twelve tests share the shapes fixture path and File::create truncates, so a write outside the lock could empty the file while another thread was parsing it.

The recorded figures came from 227 of 1,081 translation units. The full harvest supersedes them, and the defect is worse at scale rather than better: the set arm retains 1.9% of ordered events, not 2.7%, because call sites dominate and the configured-mutator rule keeps 745 of 109,603. Adds the measurement the sample could not make. Override-pair retrieval was untestable at 227 units, where only 5 of 291 declared override targets had both sides present. At 1,081 units there are 446 usable pairs, and the set arm retrieves none of them while the ordered ore retrieves 26. The order-versus-alphabet decomposition and the provenance split both hold at 6.8 times the data.

…ied test Five findings, each verified against current code first and each paired with a test confirmed to fail when the fix is removed: - The compilation-database reader split the "arguments" array on commas before parsing its strings, so a valid flag like -DPAIR=std::pair<int,int> became two invalid fragments and both were dropped, silently changing the flags a translation unit was parsed with. The array is now scanned for quoted runs. - A standalone -I lost its directory. clang accepts both -Idir and -I dir, and keeping only the bare flag hands libclang an incomplete option and loses the include path, which shows up as a partial AST rather than an error. - The override target omitted the ref qualifier while the method IRI includes it, so Base::f() & and Base::f() && both pointed at Base.f() and neither joined to the base method it actually overrides. - A subscripted assignment recorded its array as a read as well as a write. Skipping the target needed the same descent the target lookup uses, because the base arrives wrapped and a bare member-reference test never matches it. - A dereference assignment recorded the pointer member as written. *ptr_ = v changes the pointee; the member still holds the same address. A sixth finding, that a parameter's default argument contributes body facts, is NOT reproducible. Measured: with the parameter skip removed, a default argument containing both a static call and a static member read contributed no calls and no reads, because the call arm only records specific receiver shapes and reads cover own non-static members. The skip stays as scoping, its comment records the measurement, and no test claims it fixes an observed defect. The example is now a test target, so its parser tests actually run.

Five of the seven findings from the latest review are fixed in Two need an answer instead of a patch. The parameter default-argument finding is not reproducible. I removed the parameter skip and measured what a default argument can actually contribute. For The One consequence worth flagging for anyone reading the harvest numbers in Generated by Claude Code |
cargo test (linux) failed on f9a1b50 with "no entry found for key" from the shared shapes fixture: the parse found no methods, so indexing the result panicked. That is the truncation mode reported in review, and my earlier fix for it does not work. Moving the write inside CLANG_TEST_LOCK cannot help. The lock is a plain Mutex in one process, and this repository runs tests under nextest, which gives every test its OWN process. Twelve tests shared cpp_arm_shapes/f.cpp, File::create truncates, so one process could empty the file while another was inside parse(). No amount of in-process locking reaches across that boundary. Every fixture path now carries a per-process, per-call salt, which removes the sharing rather than trying to coordinate it. The comments that credited the lock with fixing this are corrected; the lock still has a job, serialising libclang within a process, and only that. Honest limit: a harness running 240 concurrent single-test processes did not reproduce the failure either before or after this change, so it is not evidence the fix works. The argument is structural instead. The precondition was read directly from the code, and unique paths make the failure mode impossible by construction rather than merely unlikely.

… in it
`absence_guard` classified any single-own-member condition by reading TOKENS
across the whole condition, and never asked where in it the member sat. So a
condition that merely MENTIONS the member was read as a test OF the member, and
the write in the branch it picked became a `guarded_write` — which
`recipe::classify` prefers over `Compute`/`Normalize`, so the method was
classified by a guard its source does not contain.
Measured before the fix, seven shapes were wrong:
if (is_ready(ptr_)) else ptr_ = v guarded
if (!is_ready(ptr_)) then ptr_ = v guarded
if (is_ready(ptr_) == 0) then ptr_ = v guarded <- the comparison
arm has the same
hole, so this is
not only the
fallback
if (count_ + 1) else count_ = v guarded
if (!(count_ + 1)) then count_ = v guarded
if (*ptr_) else ptr_ = v guarded <- tests the pointee
if (!*ptr_) then ptr_ = v guarded
`member_is_condition_subject` walks down from the condition through only those
positions that keep the member the subject: wrappers and parentheses, a logical
`!`, either side of a comparison, and the RECEIVER of a call. Not a call's
arguments, not an operand of arithmetic, not a dereference. The token table is
unchanged; this is a precondition in front of it.
Two things measurement decided that guessing would have got wrong.
An overloaded operator is also a `CallExpr`, and there the first child is the
left OPERAND rather than a callee, so `sp_ + 1` on a smart pointer reached the
member through the ordinary-call path and stayed a guard even after the builtin
`+` was rejected. The arm now reads the callee's name and treats operators as
operators.
Restricting the receiver allowance to NULLARY calls looked tidy and is wrong.
It costs three real guards on the corpus, among them
`if (prevSelVector == nullptr)` — a plain null test that is only a call at all
because the member is a smart pointer, so `==` is overloaded and arrives with
operands. `head.valid()` is the same story for the receiver chain: a rule
hardcoding `empty` would have dropped it.
Corpus impact: none. The 26 translation units carrying the 33 guarded writes
were re-harvested, and the same 33 methods come back — every guard the corpus
actually records was already a genuine subject test, so the figures in
`.claude/plans/behavioral-ore-v1.md` are unaffected. The defect was latent
here, not active. That is also why the fixtures are the evidence the fix works
and the corpus is only evidence it costs nothing.
Each negative fixture writes the member in exactly the branch the pre-fix rule
guarded, because the misclassification is silent when the write lands in the
other branch — a fixture with the write on the wrong side passes without the
fix. Three disable runs, each red then green: removing the precondition fails
only the negative test; making it reject everything fails only the three
positive tests; dropping the operator arm fails only the overloaded case.

Separately, the shared-fixture truncation is confirmed fixed rather than argued: CI run 97 on Generated by Claude Code |
The array's closing bracket was found with `contains(']')`, so a `]` inside a
JSON string ended collection early. `"-I/tmp/sdk]"` is a valid argument, and
after it every remaining flag was dropped: libclang then parses the translation
unit with a truncated flag list, which surfaces as a partial AST rather than an
error, and the harvested events are wrong for a compilation database that is
itself entirely valid.
This is the same silent-truncation class as the comma split fixed in 5a9ea47,
one level up. That one loses a single argument; this one loses every argument
after it. Both new tests put the flag that gets lost — `-DTAIL=1` — AFTER the
bracket-bearing one, since a fixture with nothing following it passes without
the fix.
`unquoted_bracket` shares its string/escape state machine with
`json_string_array`, deliberately: a scanner that disagreed with the one doing
the extraction would be a second source of truth about the same text. Both
call sites use it — the multiline accumulator and the single-line form, which
had the same bug and needed its own regression, because an array that opens and
closes on one line takes a different branch.
Written test-first: both cases failed with the truncation before the fix, and a
disable that drops only the string tracking (returning the first `]`
unconditionally) fails exactly those two and no others.

Summary
ruff_cpp_spohad a body arm that nothing could reach.method_body_armcomputed the fingerprint the fuzzy recipe codebook classifies on —writes/reads/raises/calls, plus the J1guarded_writesguard — and then discarded it, becauseCppMethodhad nowhere to put it and no expand arm emitted it. C++ was the one frontend whose method bodies produced no facts at all. This wires it end to end and corrects the draft against measured libclang behaviour.The draft was wrong in three ways, each found by dumping real cursors rather than reading the AST documentation:
if (status_ == v)reported a mutation. The operator is now read off the token stream.reads, so a pure setter classified asNormalizeinstead ofCompute.guarded_writeswas never populated, so the J1 split could not fire on C++ at all.Two shapes could not have been guessed. A class-typed member assigns through its
operator=, soname_ = sarrives as aCallExprand never as aBinaryOperator. And a call's own callee is aMemberRefExprwhose name is the method, which a naive read-collector records as a read of a field that does not exist.Also in this change:
walk_tunow parses bodies.walk_tu_configuredopts out for a signature-only walk and takes aBodyArmConfig, so a corpus can supply its own mutator vocabulary.Entity::get_definition(), andwalk_filesmerges arms across translation units. Without both, every out-of-line definition harvests nothing, which in a real C++ corpus is most of the behaviour.recipe::classifyis generic over a newBodyFactstrait implemented forFunctionandCppMethod. Its documentation already claimed it classified C++ methods; its signature accepted onlyFunction.CppMethodjoins the DTO-surface lock asCPP_METHOD_DTO, pinned againstFUNCTION_DTO.value() &andvalue() &&agree on name, parameter types and cv-qualifier, so they collapsed onto one IRI and one overload's body facts landed on both. Confirmed with a probe before fixing. It is populated from libclang, carried in the IRI suffix, recovered in reassembly by reading that suffix rather than minting a predicate, and matched in the merge key.No predicate was added; the closed vocabulary is unchanged. The C++ arm emits the same five predicates, with the same objects and truth tiers, as the Ruby and Python
Functionpath.Several stale doc claims are corrected in their own commits, including a closed-vocabulary gate named
predicate_count_locked_at_47that does not exist, a Python coverage row that had been contradicted from inside the repo, and the shared IR naming a crate that is not its frontend.Test Plan

First-wins therefore looked like a working merge. The fixture now passes-x c++and asserts up front that the header's own sighting is arm-less.The ref-qualifier has three guards, and the one covering what the walker reads runs a real parse on purpose: a hand-built fixture cannot tell a populated field from one that is always empty.

That 381 agrees exactly with an independent count of body-predicate subjects in the emitted ndjson.guarded_writesis 0 on this corpus, and that is the corpus rather than the detector. A search of the wholeladybug/srctree finds three absence tests on a member; all three are early returns or an assertion.Not verified
The census prints; nothing asserts it, so a regression would show in the output and fail no test. There is no Tesseract-side run comparable to the C# leg's real-corpus figure, and no J1 hit-rate, because this corpus contains no lazy-init writes to hit.
