The defect

src/ingest_relations.h captureFields builds the S5-E HAS-A record that feeds Rule 2b's fieldTypeByClass
(src/graph.h buildFieldNarrowTables). It read a qualified type only when a type_identifier sat directly under the
qualified_identifier. In std::unique_ptr<ToolOutputFile> OutputFile; the name there is a template_type, so the member
recorded no type at all, and every OutputFile->keep() took the bare-name ladder (a split, a locality pick or no
edge). std::string name_; was recorded (qualifier std, refused later), but no smart-pointer member ever was.

The change (decided by measurement)

  • Capture. A member written std::unique_ptr<T> / std::shared_ptr<T> records T's final segment and T's written
    namespace (so std::unique_ptr<std::string> is refused like any std type), marked viaArrow. These record nothing,
    as before: a pointer to the smart pointer, T[], a primitive, and a qualified-template pointee.
  • Receiver shape at resolve time. It was not available: RecvKind::NamedVar covers both . and ->. Every
    C++/ObjC call reference now records viaArrow (read off field_expression's operator). Rule 2b requires it on an
    arrow-only field. p->m() narrows to T::m, and p.m() stays on the unchanged ladder, because it names the smart
    pointer's own reset/get.
  • Tombstone. FlatRecvType gains arrowOnly, and recordFlatRecvTypeFact treats "T through ->" and "T as the
    member" as different facts. Two same-named classes that disagree now tombstone, as two types already did.
  • --uses=Owner.field reads the same record, so w_->level pins to the pointee's level. A std smart pointer has no
    data members, so a . read cannot mean anything else.
  • HAS-A output is unchanged. The compose block skips the new records.
  • Format. The ref record grows one u8: kCacheVersion 22 → 23, kParserVer 103 → 104 (the next free number over
    main; a train renumbers it), both quality.h mirrors, and kMinRefRecordBytes 39 → 40. Its runtime tripwire caught
    the stale value on the first run.

Rejected by measurement: recording every other std::Tmpl<…> member (vector, optional, unordered_map) as a std
type, which only tombstones same-named classes' members. On rocksdb and llvm-project that moved 6 sites and every one
got worse: 4 correct narrows lost (db_stress Stats#hist_ against db_bench's unordered_map hist_, and llvm AMDGPU
SIMachineFunctionInfo#ArgInfo against its YAML twin's std::optional), 1 turned into a wrong split, and 1 moved to the
enclosing class's own method. It refused no wrong narrow.

Measured

Method: --pin-census --no-cache on main a5ce95e2 against this branch. C rows are joined on (caller id, callee, line);
a site counts as retargeted when its target multiset differs.

corpus retargeted gained changed lost bound
rocksdb @ 0e2801ac3 809 448 355 6 +442
llvm-project @ 4d5358b1d 793 498 295 0 +501

rocksdb's 6 lost rows: five ObjectRegistry parent_->Dump()-style calls now resolve to their own method (a
shared_ptr<ObjectRegistry> parent, and the census omits self edges), and one Rep::file->file_name() is now
tombstoned where it used to hit the wrong class.

Blinded grade. A seeded (20260917), stratified sample of 60 retargets. Strata: rocksdb 12 gained / 12 changed / all 6
lost; llvm 15 gained / 15 changed. Answers were shown in random A/B order, the key was kept outside the grading directory,
and four independent graders read source under the previous lane's rubric (WRONG < NONE < PARTIAL < RIGHT):

stratum better same worse
rocksdb gained 11 0 1
rocksdb changed 8 2 2
rocksdb lost 6 0 0
llvm gained 15 0 0
llvm changed 13 2 0
all 53 4 3

The 3 worse sites are limits Rule 2b already had, now reached through a smart pointer. One is a pointee class name
(Iterator) shared with nested MemTableRep::Iterator classes. Symbol scopes drop namespaces, so Iterator::key finds
the nested ones. The other two are overload picks (WritableFile::Append, Cache::Release) that miss a default argument.

Is the -> bit worth a format byte?

  • Without it, 9 llvm sites bind the pointee's same-named method: MC.reset(new MCContext…), MII.get(),
    DT.reset(new DominatorTree…) and more. All 9 are . calls on the smart pointer. rocksdb has none.
  • A list of smart-pointer member names (refuse reset/get/… without knowing . vs ->) would also refuse 38 llvm
    narrows this change makes through -> (31 ->get(), 7 ->reset()).

Cost: the rocksdb cache grows 356,502 B (+1.15%). The warm census equals the cold one on rocksdb.

The two named llvm sites: neither is reached by this change alone (measured)

  • llvm/lib/DebugInfo/LogicalView/Core/LVReader.cpp:175 OutputFile->keep() still has no edge. The capture now
    types LVSplitContext#OutputFile as ToolOutputFile, arrow-only. But two lines up,
    OutputFile = std::make_unique<ToolOutputFile>(…) is a C++ assignment, and it mints a local binding for OutputFile.
    Rule 2b's local-shadow veto (localNameSet takes every binding kind) then refuses the member. The proof: in a
    three-file copy, deleting that one assignment line makes the site receiver-rule → ToolOutputFile::keep. With a decoy
    keep added, the unchanged copy pins the decoy instead. In C++ an assignment never declares, so this is a separate
    veto defect.
  • llvm/lib/Transforms/IPO/SampleProfile.cpp:1962 Reader->read(): Reader is declared in the base
    SampleProfileLoaderBaseImpl<FT> (SampleProfileLoaderBaseImpl.h:318). Rule 2b looks fields up on the enclosing
    class only (SampleProfileLoader#Reader), so the base-class member is never found.

Gates

test/fieldnarrowcheck.sh arm p, written first.

  • Fixture: std::unique_ptr<Widget>, std::shared_ptr<Widget> and std::unique_ptr<store::Blob> members, each
    called next to a same-named decoy.
  • Controls: std::vector<Widget> v_; v_.size(), an in-repo Holder<Widget> and an in-repo util::Box<Widget>.
  • Collisions: a std pointee and a ./-> pair, each in both record orders.

Red on a5ce95e2: p1–p4 (the narrow), p7 (--uses), all four p8 tombstones, and p9 (the warm cache).

Mutations (each built, run and reverted):

mutation turns red
ignore the -> bit p5 (w_.reset())
read through any template both p6 in-repo template controls
drop the arrow-only tombstone a p8 row

Also updated:

  • test/cachefuzzcheck.sh's record walker learns the new byte (Part 3 went red without it).
  • test/qschemetrip.hash is re-pinned for both versions, with a RE-PIN LOG entry.

Results:

  • Full suite, one run on 2e81e1dc (the fix commit): gates=646 pass=642 skip=2 fail=2 wall=1175.3s jobs=6. The skips
    are the two environmental ones (argvdiffcheck, editchecknotecheck). Both failures were one arm:
    localitycheck (6), which canoncheck also runs. That arm used std::unique_ptr<Target> rep_ as its example of "a
    member type Rule 2b cannot read", and this change makes that type readable, so rep_->pick() correctly narrowed. The
    second commit ad7a9d56 keeps the arm's intent with ns::Handle<Target> rep_ and adds arm 6b for the smart-pointer
    narrow (6b is red on a5ce95e2). After it, localitycheck, canoncheck, gateexitcheck, manifestcheck,
    gatecountcheck, versioncheck and g1freshcheck all pass. No single run is all-green: the second commit changes
    only test files, and its union with the full run is.
  • Targeted and green on the fix binary: cache family, chainguardcheck, clsrecvcheck, composelangcheck,
    cppqualcheck, cpptmplscopecheck, decltodefcheck, fieldnarrowcheck, fieldusescheck, importnarrowcheck,
    narrowcheck, narrowlangcheck, pincensuscheck, qextractionkeycheck, qschemetripcheck, rangecomposecheck,
    shadowcheck, showcasecapturecheck (graph.h is line-neutral above rankGraphTeleport), typerefcheck.
  • ASan+UBSan+LSan: fieldnarrowcheck ALL PASS under asan/ripwire with no sanitizer lines, and so were the shape probe,
    the LVReader slice and rocksdb.
  • Determinism: the rocksdb and self maps are byte-identical across runs and well-formed (xmllint).
  • --quality-delta=$(git merge-base origin/main HEAD)..HEAD: gating="0", 4 minor rows. They are captureFields
    complexity 75→81 and verbosity 121→135, captureTagsFacts verbosity +1, and recordFlatRecvTypeFact's added
    parameter. The working-tree form had also shown 3 gating short-horizon-churn rows, on the two version mirrors and
    recordFlatRecvTypeFact. All three are symbols this change has to edit, and none is in a foreign file.

Train note. kParserVer 104 and kCacheVersion 23 are claims. #278 also takes cache version 23, so the train
builder assigns the final numbers and re-pins qschemetrip.

Pins moved

…rded no type, so calls through it guessed

The member-field capture that feeds Rule 2b (ingest_relations.h captureFields) read a qualified type only when a
plain name sat directly under the `::`. In `std::unique_ptr<ToolOutputFile> OutputFile;` that name is a template,
so the member recorded no type at all, and `OutputFile->keep()` took the bare-name ladder instead: a split, a
locality pick, or no edge.

The fix, decided by measurement:
- A member written `std::unique_ptr<T>` or `std::shared_ptr<T>` records T's final segment and T's written namespace
  (so `std::unique_ptr<std::string>` is refused like any std type), marked viaArrow. A pointer to the smart pointer,
  `T[]`, a primitive and a qualified-template pointee record nothing, as before.
- Every C++/ObjC call reference records whether its member access was written `->` (RawRef/Reference::viaArrow).
  Rule 2b requires it on an arrow-only field: `p->m()` narrows to T::m, and `p.m()` is left alone because it names
  the smart pointer's own member. The ref record grows one u8: kCacheVersion 22 -> 23, and kParserVer 103 -> 104
  (next free over main; a train renumbers it), with both quality.h mirrors.
- The Class#field table's entry (resolve.h FlatRecvType) carries arrowOnly. The same type reached through `->` alone
  in one same-named class and as the member itself in another is a conflict and tombstones, as two types do.
- `--uses=Owner.field` reads the same record: `w_->level` pins to the pointee's field. A std smart pointer has no
  data members, so no `.` read can mean anything else.
- The HAS-A block draws no edge for the new records, so its output is unchanged.

Rejected by measurement: recording every other `std::Tmpl<...>` member (std::vector, std::optional,
std::unordered_map) as a std type, which only tombstones same-named classes' members. On rocksdb and llvm-project it
moved 6 sites and every one got worse: 4 correct narrows lost, 1 turned into a wrong split, and 1 moved to the
enclosing class's own same-named method. It refused no wrong narrow.

Measured with --pin-census --no-cache, C rows joined on (caller id, callee, line) against a5ce95e:
- rocksdb @ 0e2801ac3: 809 retargeted (448 gained, 355 changed, 6 lost), bound +442.
- llvm-project @ 4d5358b1d: 793 retargeted (498 gained, 295 changed, 0 lost), bound +501.
- A seeded (20260917), blinded, stratified sample of 60 retargets graded against source by independent graders:
  53 better, 4 same, 3 worse. The 3 worse sites are limits Rule 2b already had, now reached through a smart pointer:
  a pointee name shared with nested `Iterator` classes, and two overload picks that miss a default argument.
- The `->` bit is needed. Without it, 9 llvm sites (`MC.reset(...)`, `MII.get()`) bind the pointee's same-named
  method. A smart-pointer member-name list cannot replace it either, because it would also refuse 38 correct
  `->get()`/`->reset()` narrows.
- The rocksdb cache grows 356,502 B (+1.15%). The warm census equals the cold one.

Gate: test/fieldnarrowcheck.sh arm p. Red on a5ce95e: p1-p4 (the narrow), p7 (--uses), all four p8 tombstones and
p9 (warm cache). Three mutations were run and reverted:
- ignoring the `->` bit reds p5 (`w_.reset()`);
- reading through any template reds both p6 in-repo template controls;
- dropping the arrow-only tombstone reds a p8 row.
test/cachefuzzcheck.sh's record walker learns the new byte. The kMinRefRecordBytes tripwire caught the stale 39.
test/qschemetrip.hash is re-pinned, with a log entry.

Not fixed here, both measured. llvm LVReader.cpp:175 `OutputFile->keep()` still has no edge: the assignment
`OutputFile = std::make_unique<ToolOutputFile>(...)` two lines up mints a local binding, and Rule 2b's local-shadow
veto refuses the member. Deleting that line from a copy makes the site narrow to ToolOutputFile::keep.
SampleProfile.cpp:1962 `Reader->read()` names a member of the base class SampleProfileLoaderBaseImpl, and Rule 2b
looks fields up on the enclosing class only.

…ptr, which Rule 2b now reads

test/localitycheck.sh arm 6 pins the S6-C rule that an explicit receiver whose type no receiver rule established keeps
no scope-segment credit, so delegation through such a member splits instead of pinning the caller's own class. Its
example member was `std::unique_ptr<Target> rep_`. The previous commit makes that member readable, so on its binary
`rep_->pick( n )` lands on Target::pick alone (receiver-rule), the right answer. Arm 6 failed, and so did canoncheck,
which runs it. That was the full suite's only real failure: gates=646 pass=642 skip=2 fail=2.

Arm 6 keeps its intent with a member type Rule 2b still cannot read, `ns::Handle<Target> rep_` (a qualified non-std
template), and still splits over the three same-file picks. New arm 6b asserts the smart-pointer member narrows to
Target::pick by receiver-rule. 6b is red on a5ce95e (a split) and green here. Fixture line numbers are unchanged.

Recognize the global-qualified standard namespace.

For ::std::unique_ptr<Widget> and ::std::shared_ptr<Widget>, writtenTypeNamespace() returns empty. This prevents stdSmartPointee() from producing a pointee, so captureFields() emits no Widget field fact with viaArrow. Rule 2b cannot narrow p_->m() to Widget::m.

Accept a global-qualified std scope before rejecting non-standard templates.

… call through it in the derived class guessed

Rule 2b (resolve.h Narrower::rule2bFieldRecvType) typed a bare member receiver from the "Class#field" table keyed by
the caller's own class only (fieldEntryAt). A member the class inherits was never found. In llvm-project
SampleProfile.cpp, `class SampleProfileLoader final : public SampleProfileLoaderBaseImpl<Function>` calls through the
base's `std::unique_ptr<SampleProfileReader> Reader;`, and `Reader->getSummary()` took the bare-name ladder.

The fix:
- fieldEntryAt: when the class declares no member of that name, walk its bases breadth-first over chaUp (final-segment
  names, the discipline methodOnTypeOrBases uses). The shallowest level with a base DECLARING the member decides, and it
  must be exactly one base; its typed entry is returned (a tombstone or an arrow-only pointee is handled as before).
- "Declared" is the field side table (IngestResult::fields, Narrower::memberFieldNames), typed or not. An untyped member
  of the class itself, or of a base at a level before the hit, hides the bases behind it and refuses. So do two
  declaring bases at one level (an ambiguous lookup) and a walk the 16-name cap cut with a base unvisited.
- The local-shadow veto is unchanged. prov="final-segment" (fieldFinalSegmentAt) reads the same walk.
- Rule 2b's tables travel as one FieldRecvTables bundle (types, declared, chaUp), so no signature grows.
  kFieldWalkCap is hoisted to the struct, and methodOnTypeOrBases shares the base expansion (expandWalkLevel); its
  visited set, and so its answers, are unchanged.
- graph.h builds the declared-member set once beside the Narrower and stays line-neutral above rankGraphTeleport.
  docs/LIMITS.md is regenerated for kFieldWalkCap's note (value and class unchanged).
  lane/rule2c-member-field (redhat-et#280) builds the same set under the same name for Rule 2c; a train keeps one.

Dependent bases were measured, not refused. C++ lookup never searches a class template's dependent base for a bare name,
but the base clause records no template arguments, so a refusal needs an extraction change. A source scan of every
retarget found 5 of 2,203 sites in a class template with a dependent base, and all 5 are correct: three
PtrUseVisitor sites reach its non-dependent PtrUseVisitorBase, and two ELF_ppc64.cpp sites reach `using Base::G;`. A
refusal would lose five right edges and fix none. It stays a pinned floor (arm v12).

Measured with --pin-census --no-cache, C rows joined on (caller id, callee, line):

  - llvm-project @ 4d5358b1d: 1,829 retargeted (731 gained, 1,098 changed, 0 lost), bound +735.
- main a5ce95e -> this one (includes redhat-et#282):
  - rocksdb: 1,183 (684 / 493 / 6), bound +678;
  - llvm: 2,622 (1,229 / 1,393 / 0), bound +1,236.
- A seeded (91717), blinded, stratified sample of the lane's retargets (rocksdb gained 10, changed 10; llvm gained 20,
  changed 20) was graded against source by independent graders: 52 better, 3 same, 5 worse. In all 60 the grader traced
  the receiver to a member of a base class. The 5 worse sites are Rule 2b's existing type-side limits: a class name
  shared across namespaces (llvm::Module / sandboxir::Module x2, Sema / comments::Sema x1) and two overload picks that
  ignore the argument count. The 3 same are rocksdb DB::Get/Put overload picks, WRONG on both sides.
- Refactor steps were checked census-byte-identical on both corpora against the graded build. llvm wall time is 4.7 s
  on both builds.

Not fixed, measured: SampleProfile.cpp:1962 `Reader->read()` still declines. `Reader = std::move(ReaderOrErr.get());`
five lines up records a local binding, and the veto refuses the member. A fixture reproduces it, and deleting that line
narrows it. It is the same shape as LVReader.cpp:175 in redhat-et#282. `--uses=Owner.field` keeps its own class-only member
lookup; its legend discloses the inherited field as not seen.

Gate: test/fieldnarrowcheck.sh arm v (generated fixture).
- Red on ad7a9d5 (8 FAIL): v1 x3 (unique_ptr, raw pointer, out-of-line method), v2 (two levels), v4 (the narrow and
  its prov), v10 (the 16th name), v12 (floor). The same 8 are red on main. Controls v3, v5-v9, v10 far and v10w are green.
- Mutations on a scratch build, reverted:
  - counting only typed members as declared reds v6 and v7;
  - taking the first declaring base reds v8;
  - probing a cap-cut level instead of refusing reds v10w.
- Green here. v11 is census determinism.

…nto train 5 — kParserVer 114

lane/rule2b-assignment-veto 626810b (signed off; redhat-et#282 + 8f16d3e + 626810b). The lane declared kParserVer 112 over
redhat-et#282's 104; main had spent 112 and redhat-et#282 takes 113, so integration/train-5 assigns 114 (mirror moved; no record layout
change, kCacheVersion stays 24).

Resolutions:
- src/resolve.h: main's type-alias bases, classNameSet and redhat-et#278's assignmentNamesNoClass beside the lane's
  localNameEvidence; rule2cClassNameRecv keeps main's ClassNameRecvNames signature (redhat-et#280's memberFields) with the lane's
  wording for condition (2).
- src/graph.h: localNameSet takes the lane's evidence bits AND keeps main's VarDecl localShadowSpans (Java shadows).
- A composition call, not a textual one: main's localNameSet loop skipped a record assignmentNamesNoClass drops (redhat-et#278:
  a member assigned from a call read as a local, so Rule 2b refused its declared type). The lane solves that same
  refusal with the declared bit, and its arm v3 needs Rule 2c to keep the assignment as evidence the token is a variable
  (`Widget = makePane();`), which the skip would drop. The loop now reads every record; assignmentNamesNoClass still
  guards the varType and field use-site tables, and its comment says the local-name set joined the two.

…he train assigned

The three members each wrote their entry at the top of Unreleased over their own base. Moved to the end of Unreleased
in merge order — redhat-et#282, then the veto lane's two (its ingest fix first, which its own entry now points up to), then
field-base-member — and the version sentences renumbered to the train's: kCacheVersion 23 -> 24 and kParserVer
112 -> 113 for redhat-et#282, 113 -> 114 for the veto lane. field-base-member changes no extraction and names no version; its
gate arm reads (w), the letter it took when both lanes had added an arm (v).

…ts RE-PIN LOG entries

The pin is re-derived on the final merged tree and carried from no member: 96ffda46. TRAIN 5's entry records the
numbers assigned in merge order (kParserVer 113 for redhat-et#282, 114 for the veto lane's ingest fix; kCacheVersion 24), and
the veto lane's own entry is added — it changed the manifest source without one.

…ch the two lanes made readable

Found on the merged tree; no member's own CI could see it. redhat-et#280's arms H and J assert that a member named like a class
takes no receiver rule, because neither member had a type Rule 2b could read: H is `std::unique_ptr<Widget> Reader`
and J is the base's `Widget* Inherited`. redhat-et#282 records a smart pointer's pointee and lane/field-base-member walks the
bases, so both now resolve to `Widget::read` — the member's own type, exactly what arm I already asserted for
`Widget* Raw`.

H and J move to memberTypePin, arm I's assertion: receiver-rule to Widget::read ALONE, never the class the token names.
K (a class template's base) and L (past the 16-name walk cap) keep notClassPin — Rule 2b still types neither — and the
M/N controls are untouched.
