The compiler now checks the tables, switches, masks and layouts that this tree's defects came from. On the way, two
wrong-answer defects turned up and are fixed. Review found a third, --from-trace printing a bundle without its blocks,
and a double count that this lane's own .pyi row introduced. Both are fixed here too.

Seven commits, one per item, then the review's fixes as four more commits. Each check was shown failing on a deliberate
break before it landed; the red-first table is in each commit message.

Fixed

1. Five code extensions were no language to the dependency, state and lint verbs. The crawl indexes .metal, .cu
and .cuh as C++, .pyi as Python and .phtml as PHP. langOfPath (src/lintrules.h) is the classifier that
--deps, --arch, dep_capable=, --nonlocal-state, --quality-panel, the lint catalog and --lint-rules use, and it
called those files Unknown. includeLangOf (src/resolve.h) had the same C++ and Python gaps.

  • Both tables now know all five.
  • The .hxx row is gone from both. The crawl admits no .hxx file, so neither row could ever be reached.
  • test/deplangscheck.sh arm (G) requires the two tables to agree. It went red with only the classifier rows added,
    naming exactly .cu, .cuh, .metal, .pyi and .hxx.

Measured by comparing stdout and exit code, --no-cache, over all 162 fixture corpora and eight verbs (1,296 runs),
against a f8e6087c binary and again against a 31e788ce binary:

  • The same 14 runs differ both times. They are all on the six corpora that hold one of the extensions, and all on
    --deps, --nonlocal-state or --quality-panel.
  • test/cudafix --nonlocal-state: cells goes 0 → 5 and functions 0 → 4.
  • test/cudafix --deps: dep_files goes 1 → 3, and the kernel's include of reduceShared.cuh now counts.
  • test/metalfix --deps: the shader's row was already printed. It now counts in dep_files (2 → 3), and its quote
    include of AAPLSharedTypes.h resolves.
  • A language: cpp rule run over a shader and a kernel reported findings="0"; it now reports 16.
  • .pyi stubs (review F1). A stub restates its module's globals (COUNT: int beside COUNT = 0), so counting both
    files turned one cell into two. --nonlocal-state and --quality-panel now skip a stub whose .py is indexed beside
    it. A stub with no source, the shape a C extension ships, keeps its cells: test/pyshapefix goes 5 → 6.
    test/nonlocalstatecheck.sh arm (J) was red at cells="2" before the skip.

2. A memory buffer that lost a write was read back as a whole document (23 sites). Measured with a
DYLD_INSERT_LIBRARIES interposer that fails one realloc inside open_memstream, on macOS 26.5.1:

  • In 19 of 19 runs, one fwrite came back short and the stream's error flag was set.
  • Each run lost 152–976 bytes from the middle of the document.
  • fflush and fclose both returned 0 every time. So renderToString's check (ccdb7c0) could not see this failure,
    and 22 other sites did not check at all.

The fix:

  • rw::MemoryStream (src/infra/emit.h) now owns every buffer, using RAII and no exceptions. Its [[nodiscard]] finish() flushes, reads ferror, closes, and reports the result by value.
  • Every site takes the path a failed open already took. The map and the JSON map are rendered again, whole.
  • Two surfaces have no second rendering, because the buffer holds the answer itself. Both print nothing, say why on
    stderr in every build, and exit 1:
    • the --token-budget map;
    • --from-trace and --run-trace (review F2b), when the <trace> map, the test hop or the signature/body section
      loses its buffer at the open or at the finish. The MCP from_trace verb answers -32603. These blocks used to be
      left out of a bundle printed at exit 0, silently in Release: 2,385 bytes with no <trace> against the control's 3,301.

Gate changes in test/estchargecheck.sh:

  • #14f uses a debug-only fault switch, INFRA_FAULT_MEMSTREAM_FINISH=1, that makes every finish fail. It asserts
    four surfaces, not every site: the --pack-signatures and --json maps come out byte-identical outside est_tokens
    at exit 0, and --token-budget and --from-trace each print nothing and exit 1 where their controls answer.
  • #14g refuses any hand-written memstream handling. It finds 46 lines on f8e6087c. Its positive control puts one
    site back by hand once per opener spelling (bare, ::, os::, rw::os::), and the pre-review pattern missed the
    close for three of the four.

Changed: compile-time checks

  • Language registration. src/main.cpp and src/ingest_crawl.h assert that every code Lang appears in the
    nonlocal, lint-vocabulary, catalog and extension tables, and that langOfPath and the crawl agree. Each check returns
    the first failing index, and isCodeLang has no default:.
  • -Werror=switch -Werror=implicit-fallthrough on our C++ targets, for every compiler. Until now GCC ran no
    -Wswitch at all. Eleven per-enumerator switches lost their default:. Dart is now decided explicitly in
    dependencyCapable and dependencyDialect: it has no import capture, which a probe confirmed.
  • Cache and layout facts:
    • the kParserVer/kCacheVersion mirror in quality.h is asserted equal to the real constants;
    • CacheEntry must have unique object representations;
    • qsnapPut is constrained the same way;
    • ingest() carries sizeof( Symbol ) and sizeof( IngestResult ) in its mangled name. This was measured on this
      tree: a mixed-layout object pair now fails to link, while the same pair without the stamp linked and crashed with
      SIGBUS.
  • The redaction first-byte mask is checked bit for bit against the rule table it hand-numbers.
  • Shift width against count for every mask a runtime value is shifted into: the language, family, rule and pack-task
    masks and strkern's block masks.
  • Tables indexed by an enum get deduced extents, with counts proven by infra/enumcount.h (fix(cache): a cached enum byte past its enum's last value was believed, and a span-tier memo byte wrote past a stack array #241).
    kNodeFieldNames rows name their enumerator. skilleval's provHit[3] was too small for a four-value Prov.
    The new test/enumtablecheck.sh refuses a literal-extent table indexed by an enum. It finds 14 subscripts on
    f8e6087c, and its three positive controls each go red. A control counts only the violations its own mutation adds
    (review F3), so a real violation in the tree fails the rule arm alone instead of every control.

Gates

Each gate was run as its own script with its exit code read, never via --only. At d41c7e4c, 77 gates were all rc 0 with 0 FAIL. At c1ce76c0, after merging bcd3b016, 28 gates were all rc 0 with 0 FAIL: enumtablecheck, estchargecheck, crashsweepcheck, cppqualcheck, gatecountcheck, manifestcheck, gateexitcheck, nonlocalstatecheck, pyshapecheck, tracecheck, runtracecheck, tracehopcheck, tracehandoffcapcheck, mcpeditracecheck, mcpverbscheck, mcpcontractcheck, mcptranchecheck, mcpattrparitycheck, qualitypanelcheck, deplangscheck, binoverridecheck, limitstablecheck, printffmtparitycheck, versioncheck, xmlwellformed, skipclassifycheck, pargatescheck and fieldidcheck. The only skips were environmental or on-demand: tiktoken is not installed, gateexitcheck (E) runs on demand, and two arms have no sample in their corpus. No local ASan binary was built (the machine rule).

A merge with #249 turned crashsweepcheck S2 red with no text conflict: twelve memstream rows named functions that now hold a MemoryStream, and the stream's own opener had no row. The stale rows are gone and infra/emit.h's opener is registered. MemoryStream's opener overload is renamed openWith, because S2 counts calls by name and read open() forwarding to open( Opener&& ) as a raw POSIX open.

Probes on this head: a .py + .pyi pair gives cells="1" bound to m.py under --quality-panel and --nonlocal-state, and a lone stub gives cells="1". The MCP from_trace verb answers normally, and under the fault switch it answers -32603.

Warnings: 0 on the dev build. With -fsyntax-only, the four configurations {AppleClang 21, Homebrew clang 22} ×
{debug, -DNDEBUG} over the two binaries' translation units and the four test harnesses give 36/36 rc 0 with 0 warnings at e9dcbe4b. Every later head was built with the same flags at 0 warnings on AppleClang.

--quality-delta over the merge-base range (bcd3b016..c1ce76c0): gating="0", acked="21". The lane's 13 acks
went through the binary, each with its reason (see chore(quality)).

Not verified locally: GCC. CI's gcc legs are the first run of:

  • -Werror=switch;
  • the trailing returns that -Wreturn-type needs;
  • requires has_unique_object_representations_v;
  • constexpr std::ranges::find with a projection;
  • the redaction-mask constexpr;
  • the stamp's mangling.

enumCountIsExact runs on clang only (#241). The langTag( Lang( kLangCount ) ) assert is its GCC-portable twin.

Shared products

  • Gate count: new gate enumtablecheck. The loop is unioned and the count regenerated to 622.
  • CHANGELOG.md: one ### Changed and two ### Fixed entries, directly under [Unreleased].
  • test/crashsweepcheck.sh S2 registry: 12 rows out, the infra/emit.h opener in. CONTRIBUTING.md: the catch-block count, re-derived (26 blocks, none releases by hand).
  • Gate registration files: .github/pargates-shard-weights.json and test/binoverridecheck.sh's EXEMPT list.
  • .ripwire_quality_acks: 13 rows.
  • CMakeLists.txt: warning flags (not cmake/PortableFlags.cmake).
  • Unchanged: kParserVer, kCacheVersion, the qschemetrip hash, test/printf_parity.manifest and the
    docs/COMMANDS.md captures.

Pins moved: none, apart from the generated gate count.

…the dependency, state and lint verbs, and nothing checked the registration tables

THE DEFECT. langOfPath (lintrules.h) buckets an indexed file by language for --deps/--arch, co-change's dep_capable=,
--nonlocal-state, --quality-panel, the lint catalog and user --lint-rules, from its own extension table "kept in sync
by hand" with the crawl's kLangTable. It had drifted: .metal, .cu and .cuh (C++), .pyi (Python) and .phtml (PHP) are
parsed by the index and were Unknown to every one of those verbs. It also carried .hxx, which the crawl never admits.
resolve.h's includeLangOf, the includer-dialect table, had the same four C++/Python gaps.

THE FIX.
  * The five extensions join langOfPath's table; .metal/.cu/.cuh (CFamily) and .pyi (Python) join includeLangOf, so a
    file now counted in the dependency denominator can also resolve its includes (test/deplangscheck.sh arm (G)
    refuses the one without the other, and did: RED with the lint rows alone, naming .cu/.cuh/.metal/.pyi and .hxx).
    The dead .hxx row leaves both tables. atoms.h's private .cu/.cuh/.metal workaround goes.
  * The registration becomes compile-time. src/ingest_crawl.h: every CODE kLangTable row is in kLintExtRows under the
    same Lang, no data/doc row is, every lint row names a crawl row, no row is empty. src/main.cpp: every code Lang is
    analysed or disclosed unanalysed by --nonlocal-state, and is named by kLangTokenRows, lintcatalog::kCatalogLangs
    and kLintExtRows; langTag( Lang( kLangCount ) ) is "?" (the GCC-portable twin of #241's enumCountIsExact). The
    tables are hoisted to namespace scope with deduced extents. model.h's isCodeLang, a switch with no default, is the
    one declared exemption. Every check returns the first failing INDEX: an empty-string sentinel passed a zero-filled
    row in the survey's first draft.

MEASURED (base f8e6087 vs this change, --no-cache, stdout+rc byte-compared): 162 fixture corpora x 8 verbs
(map, --json, --deps, --nonlocal-state, --lint, --lint-catalog, --quality-panel, --pack-signatures) = 1,296 runs; 14
differ, all on the six corpora holding one of the extensions, all on --deps / --nonlocal-state / --quality-panel.
test/cudafix --nonlocal-state cells 0 -> 5, functions 0 -> 4; --deps dep_files 1 -> 3 with the kernel's include of
reduceShared.cuh counted (afferent 1 -> 2). Without the includeLangOf rows the same corpus read dep_files 3 at nccd 0.80
and shape="horizontal" — the dilution arm (G) exists to prevent; with them, nccd 1.00, "vertical". test/phpfix
unanalyzed_files 4 -> 5. A language: cpp user rule over a .metal shader and a .cu kernel: findings 0 -> 16.

RED FIRST (-fsyntax-only, AppleClang 21; each variant proven to change the file, restored and git-clean after):
  drop "dart" from kLangTokenRows            main.cpp:587 firstLangLintCannotName() — '21 == 23' (21 = Dart)

… leg, and GCC never ran -Wswitch at all

THE DEFECT. CMakeLists.txt passed no warning set, so -Wswitch ran only because Clang enables it by default, as a
warning nobody reads, and GCC (which enables it only under -Wall) did not run it at all. Worse, eleven switches that
return one answer PER ENUMERATOR carried a `default:`, which silences it even where it runs. Appending an enumerator
landed silently in each: dependencyCapable and dependencyDialect never decided Dart (it fell to `default: false` the
day it was appended, 70611d7), and dedupRawDefs' specificity ranking folded Macro and Section into "Other" unnamed.

THE FIX. `-Werror=switch -Werror=implicit-fallthrough` on RIPWIRE_OWNED_CXX_TARGETS (ripwire, ripwire_probe, and the
four test harnesses under RIPWIRE_TESTS), for every compiler; never on the tree-sitter core or the generated grammar C.
The per-enumerator switches name every enumerator and end with a plain `return` for a byte past the enum (GCC's
-Wreturn-type needs it): symTag, langTag, refRoleTag, accessshape's shapeName/confidenceName, parseDocFile's outer
and inner switch, styleTag/recombineToStyle, glyphName, skillSeverityStr, namespaceCompatible, the specificity
lambda, isControlKind, dependencyCapable, dependencyDialect. Deliberate-subset switches keep their default.

DART, DECIDED. Dart stays not dependency-capable, now by name. The rule dependencyCapable states is "has a node-type
branch in captureIncludes", and Dart has none (no kImportContainersByLang row, no import_or_export branch in
directiveTargetOf, no Step-A in resolve.h). Measured on a two-file probe with `import 'util.dart';` beside a C++
include pair: --deps printed the C++ `<inc t="b.h"/>` row and nothing for the Dart file.

MEASURED. 0 warnings: -fsyntax-only with the two flags over main.cpp, ingest.cpp, pagerank.cpp, infra/diagnostics.cpp,
tsprobe.cpp and the four test harnesses x AppleClang 21 and Homebrew clang 22 x debug and -DNDEBUG = 36 compiles, all
rc 0; the dev build 0 warnings. GCC is not on this host: CI's gcc legs are the first run of -Wswitch there (the clang
0 covers the same rule; GCC's -Wimplicit-fallthrough also accepts fall-through comments, so it is the more lenient leg).

RED FIRST (-fsyntax-only, AppleClang 21):
  append SymKind::Module          model.h:70: enumeration value 'Module' not handled in switch [-Werror,-Wswitch]
  drop a `break;` in recombineToStyle  namingconsistency.h:179: unannotated fall-through between switch labels

…d, and a mixed-layout build that linked

THE DEFECTS.
  * quality.h's kIngestParserVerMirror / kIngestCacheVersionMirror must equal kParserVer / kCacheVersion, or quality
    snapshots computed under an old extraction are re-served (quality.h's r27 note). Only test/qextractionkeycheck.sh,
    parsing both files as text, held that, and quality.h's own comment asked for a static_assert as a FOLLOW-UP.
  * CacheEntry's `sizeof == 32` assert says "no padding" and cannot prove it: a u16 recSum still rounds up to 32
    bytes, leaving two indeterminate bytes in every row of a committed, checksummed blob.
  * qsnapPut asserted trivially_copyable, which admits a padded struct or a float (-0.0 vs 0.0) into a blob that must
    be byte-stable. Every call site passes a fixed-width integer; nothing kept it that way.

THE FIX. static_assert the mirror in ingest_cache.h (the translation unit that includes both); static_assert
has_unique_object_representations_v<CacheEntry>; constrain qsnapPut with `requires
has_unique_object_representations_v<T>`. None of these touch std::pair/optional/tuple, whose answers can differ by
standard library.

THE LAYOUT LINK STAMP. CLAUDE.md records three builds that linked objects compiled against two struct layouts and
reported success (the fake ASan overflow, the "impossible" length_error). ingest() gains a trailing, defaulted
IngestLayout = IngestLayoutStamp<sizeof( Symbol ), sizeof( IngestResult )>, so both sizes enter its mangled name.
Landed only because the link failure was MEASURED, in a scratch experiment on this tree with the dev build's own flags
and link line (ct-lane/stampexp.sh):
  N  no stamp, main.o at sizeof( Symbol ) 112 + ingest.o at 120 (one u64 added)   link rc 0; the binary died SIGBUS (138)
                                                                                    on test/fixture
  S  stamp, the same mixed pair                                                     link rc 1: undefined
                                                                                    rw::ingest(…, IngestLayoutStamp<112, 848>)
                                                                                    beside a defined <120, 848>
  C  stamp, consistent pair                                                         link rc 0, output byte-identical to the
                                                                                    dev binary on test/fixture
sizeof( IngestResult ) stayed 848 on both sides, which is why Symbol is named separately. It covers two of CLAUDE.md's
three instances; the third (a stale constant, not a layout) is the mirror assert's case above.

RED FIRST (-fsyntax-only, AppleClang 21):

… document, at 23 sites

THE DEFECT. Twenty-three places render into an open_memstream buffer and read it back: serialize()'s and
serializeJson()'s children, chargeSection, the JSON header probe, the two --max-tokens fit probes, the --token-budget
buffer, the --for lens's pre-rendered sigs/lego/compose/routes and JSON sigs, three --from-trace blocks, seven MCP
answers, and renderToString. Twenty-two flushed and closed without reading either result. The one that did read
them (renderToString, ccdb7c0) could not see the failure it looked for.

MEASURED, not assumed: a DYLD_INSERT_LIBRARIES interposer failing ONE chosen realloc inside an open_memstream on
macOS 26.5.1 (Apple libc), streams of 5 KB / 50 KB / 200 KB written in 1 KB chunks. In all 19 runs where the failure
landed inside the stream: one fwrite short, the error flag set, 152-976 bytes lost from the MIDDLE (as late as chunk
177 of 200), `sz` short — and fflush and fclose both returned 0. So the checked seam passed a document with a hole.

THE FIX. One owner, rw::MemoryStream (infra/emit.h, RAII, no exceptions): open() through open_memstream or a
caller's opener; [[nodiscard]] finish() flushes, reads ferror, closes exactly once, and reports BY VALUE
(MemoryStreamBytes{ bytes, isWhole }); the destructor closes an unfinished stream and frees the buffer on every path,
so no site frees or closes by hand. serialize.h's openChargeStream keeps the est_tokens fault switch in front of every
charge buffer. Each site takes the path a failed open already took:
  * serialize / serializeJson: the children become one renderer both paths call, and the map is RENDERED AGAIN
    straight to the output with the modelled est_tokens — whole, never the short bytes;
  * chargeSection: isRendered stays false, so emitChargedSection renders the section directly, uncharged;
  * the fit probes answer "unmeasured" (0); the JSON header probe charges the modelled envelope;
  * the --for blocks are emitted directly (sigs also drops what the failed render measured); JSON sigs unbudgeted;
  * the trace blocks and MCP answers answer as a failed open does (connect: "internal error");
  * the --token-budget buffer, the one that IS the answer: nothing on stdout, stderr "write error — the
    --token-budget buffer lost bytes", exit 1 — in every build.

THE GATE, test/estchargecheck.sh:
  #14f  INFRA_FAULT_MEMSTREAM_FINISH=1 (debug-only, exact "1") makes every finish report failure after really
        closing. --pack-signatures and --json maps come out byte-identical to the undegraded run outside est_tokens,
        well-formed, exit 0, est_tokens modelled (467 vs 4461); --token-budget prints 0 bytes and exits 1 where its
        control prints 2234 B at exit 0.
  #14g  refuses open_memstream, a direct openChargeBuffer call, or an fflush/fclose of a memory stream outside the
        type. RED on f8e6087: 46 lines. Positive control: one tracelocus.h site put back by hand -> exactly its two
        lines reported.
  Standalone at e9dcbe4b: estchargecheck 225 PASS / 0 FAIL / 1 SKIP (tiktoken not installed).

…nd an inserted rule would silently never fire

THE DEFECT. buildFirstByteRuleMask spells `addRule( 0, {'A'} ) … addRule( 9, generic )`, a second copy of
kRedactRules' ORDER. Insert a vendor rule at index 2 and every later index points one rule off: each later rule is
tried only at bytes its pattern cannot start with, so it never matches — a redaction that stops firing, with no test
failing unless a fixture sits at exactly that rule. The rule-count bound sat inside redactSecrets, away from the mask
it bounds.

THE FIX. Both builders become constexpr and firstRuleTheMaskMisnumbers() recomputes the mask from the table at
compile time, bit for bit: a literal-prefixed rule owns exactly the bit at its pattern's first byte, the one
GenericAssigned rule owns exactly its character class, and no other rule may start with a regex metacharacter. It
returns the first mismatched rule INDEX. The kRedactRules.size() <= 16 bound moves beside the builder as
`<= numeric_limits<uint16_t>::digits`. The two per-process static tables become `static constexpr` (no guard, no
per-process build); the mask's values are unchanged, so no redaction changes.

RED FIRST (-fsyntax-only, AppleClang 21):
  insert a `glpat-` rule at index 0 (10 -> 11 rules)
      redact.h:380: static assertion failed … firstRuleTheMaskMisnumbers() == kRedactRules.size() — '0 == 11'

… bound beside the mask

THE DEFECT CLASS. A shift by a value at or past the mask's width is undefined behaviour. clones.h:135 shifts a
32-bit language mask by a Lang at runtime; a Lang byte of 255 from a cache is the reader's to refuse (#241), but
nothing tied the ENUM'S OWN range to the mask's width except a hand-written `kLangCount <= 32` on one of the three
language masks. The same shape recurs with families, rules and blocks.

THE FIX. Every mask a runtime index is shifted into pins its count to its width with
`static_assert( kCount <= std::numeric_limits<MaskType>::digits )`, read off the mask's own type where it has one:
  langBit / kHashLineCommentLangMask / LintCatalogRow::langMask   kLangCount           (clones.h, lintcatalog.h)
  EnsembleRow::firedMask / EnsembleFileRow::unionMask             kFamilyCount         (ensemble.h)
  the quality-panel family masks                                  kPanelFamilyCount    (qualitypanel.h)
  firedRuleMask                                                   kRuleCount           (renamemine.h)
  selectMonotoneBodySubset's `1u << n`                            kPackTaskBodyCandidates, plus VERIFY( n <= it )
  strkern::Masks                                                  kMaxBlockBytes       (infra/strkern.h)
The redaction rule mask's bound moved beside its builder in the previous commit; search.h's per-tier serveMask is
#241's `kSpanTierCount < 8`.

RED FIRST (-fsyntax-only, AppleClang 21):
  langBit returns u16                 clones.h:121: 'kLangCount <= numeric_limits<unsigned short>::digits' — '23 <= 16'
  kRuleCount 8 -> 33                  renamemine.h:494: '33 <= 32'
  kFamilyCount 4 -> 9                 ensemble.h:238: '9 <= 8' (and kFamilyNames' size assert, '4 == 9')
  kMaxBlockBytes 32 -> 64             strkern.h:110: '64 <= 32'

…mpile, and nothing refused a literal extent

THE DEFECT CLASS. A table indexed by an enum must be as long as the enum. A spelled extent makes a missing row a
zero-filled tail (a null the emitter prints, or a read past the data), and it made several existing size asserts
restate their own declaration. Instances on main: skilleval's provenance counters `provHit[3]` for a four-value Prov
(Prov::Neg one past the end behind a debug-only check), search.h's `tierHitCount[3]` (#241 fixed it with
kSpanTierCount), redact.h's kLabel sized by SecretKind::kCount so a missing label zero-fills, kEvWhyTagTable[
kEvWhyTagCount ] with a hand-written 8 beside EvWhyTag, crossref's kTag[ kVerdictCount ], kArmName[kArmCount],
kPropNames[kPropCount], kPassName[kPassCount], std::array<PresetRow, 3>, std::array<const char*, 2> kNewFamilyNames,
the two per-family slice tables spelled [ SliceFam::None ], and no size assert at all on kAnchorKindTag, kDriftTag,
gateKindTag's table, kSplitName or kProvName. And kNodeFieldNames pairs with NodeField BY INDEX only, so a field
inserted mid-enum re-maps every field after it (#233 appends NodeField::Op).

THE FIX (#241's pattern, merged): deduce every such extent, count the enum beside its declaration and prove the count
exact with infra/enumcount.h's enumCountIsExact (kAnchorKindCount, kDriftCount, kGateKindCount, kSplitCount,
kProvCount, kPresetCount; EvWhyTag, Verdict and ClaimShape against their existing counts), and static_assert each
table's size against it. kNodeFieldNames rows now name their enumerator, and firstNodeFieldRowOutOfPlace() returns
the first row whose enumerator, spelling or declared length is wrong (an INDEX, so a zero-filled row cannot pass).
contentBytesByLang spells its extent and its clamp from Lang::Unknown. The slice tables' row count is asserted where
they are read.

THE GATE, test/enumtablecheck.sh (new, no binary; registered in regression.sh, binoverridecheck's EXEMPT, the shard
weights; gate count 618 -> 619 by docs/gatecount_build.py): no C array or std::array with a LITERAL extent is indexed
by an enum — an enumerator, an unscoped enumerator, a member declared with an enum type, or a name whose nearest
declaration is one of those. One exemption with its reason (filter.h kDocTierTags: a two-bool composition). RED on
f8e6087: 14 subscripts over five tables. Three positive controls, one per detection path, each re-introducing one
real literal and required to report exactly that table. test/fieldidcheck.sh's harvester reads the new row shape and
refuses a row naming another enumerator.

RED FIRST (-fsyntax-only, AppleClang 21):
  swap NodeField Alias/Alternative rows     fieldid.h:130: firstNodeFieldRowOutOfPlace() — '0 == 42'
  insert NodeField::Op mid-enum             '24 == 43'
  declare "name" with length 5              '22 == 42'
  drop "range-straddles" from kDriftTag     docdrift.h:172: '8 == 9'
  drop "jwt" from kLabel                    redact.h:654: '8 == 9'
  drop the Rust row of kSliceStmtContainers slice.h:882: '5 == 6'
  append Preset::Custom / EvWhyTag::Yield / Verdict::Stale   enumCountIsExact<…> failed (clang-evaluated; see below)
The enumCountIsExact proofs are evaluated on clang only (enumcount.h says so); on the GCC legs the deduced-size
asserts still hold and the enumerator appends are caught by the clang legs of the same CI run.

Two text conflicts, resolved by content: test/regression.sh's loop is the UNION (#244's diagnoticecheck beside this
lane's enumtablecheck), and docs/gatecount_build.py rewrote the count it produces (620); CHANGELOG.md keeps both sides,
this lane's three entries directly under [Unreleased].
…nces make by construction

--quality-delta over the merge-base range (31e788c..d41c7e4) reported gating="11", every one read. Acked through the
binary (--quality-ack with --ack-only, three calls, 13 ledger rows), none by kind alone:
  * nine duplication / new-clone-of-reused-helper rows between per-enumerator switches (shapeName, symTag, refRoleTag,
    isCodeLang against their siblings). Naming every enumerator with no default: is what makes -Werror=switch fire at
    each switch when an enumerator is appended; two such switches over one enum share its spelling by construction.
  * two rows between qsnapPut and ByteW::u32: the constraint replaced the assert, leaving the same one-line append in
    two translation units that cannot share a header.
  * two nesting rows (serialize 5 -> 6, serializeJson 4 -> 5): the children and the rows became one renderer lambda that
    the buffered path and the whole re-render both call.
After: gating="0", acked="20", 17 non-gating regressions left visible (complexity growth in the same two renderers,
ingest()'s params 7 -> 8 for the defaulted layout stamp, the new gate's scan function).

One text conflict: test/regression.sh's loop is the UNION (#250's tempfilesymlinkcheck beside this lane's
enumtablecheck), and docs/gatecount_build.py rewrote the count it produces (621). This lane's CHANGELOG entries stay
directly under [Unreleased].
Two text conflicts, resolved by content: test/regression.sh's loop is the UNION (#249's crashsweepcheck beside this lane's
enumtablecheck), and docs/gatecount_build.py rewrote the count it produces (622); CHANGELOG.md keeps every entry, this
lane's three directly under [Unreleased]. crashsweepcheck's registry is reconciled in the commit after this one.
…er open a stream, and not the one that does

Merging #249 beside this lane's rw::MemoryStream turned crashsweepcheck S2 red with no text conflict. Its registry keys
every raw opener by (file, enclosing function, opener, count), and twelve open_memstream rows (renderToString,
openTokenBudgetBuffer, seven MCP verbs, three tracelocus blocks) now name functions that hold a MemoryStream instead,
while the one call that does open a stream — MemoryStream::open in infra/emit.h — had no row. The twelve go, the owner
gets its row ("owned": the destructor fcloses an unfinished stream and frees the buffer on every path; finish() closes
exactly once), and serialize.h openChargeBuffer's reason names its only caller, openChargeStream, which hands the stream
to MemoryStream::open.

CONTRIBUTING's catch-block measurement was dated to 216802a and named renderToString as the one handler that releases a
resource by hand. Re-derived on this branch, comment and string context excluded: 26 catch blocks, none releases
anything by hand (bare grep 34); the paragraph now says both measurements and which one is current.

…s twice

Once langOfPath learned `.pyi`, a typing stub's restatement of its module's
globals (`COUNT: int` beside `COUNT = 0`) became cells of their own. A
two-file probe went from cells="1" to cells="2" with every row still bound
to m.py, so --nonlocal-state and --quality-panel over-counted every stubbed
Python module.

discoverCells now skips a stub whose same-stem `.py` is indexed. A stub with
no source beside it, the shape a C extension ships, is the only declaration
of its module the index holds and keeps its cells.

Gate: test/nonlocalstatecheck.sh arm (J) pairs m.py with m.pyi and wants
cells="1" bound to m.py, with a stub-only control at cells="1". It went red
at cells="2" on 109e7eb.

…uffer

Under a failed memory buffer, at the open or at the finish, renderTraceBlock
and renderTestHopBlock returned "" and the signature/body section was
skipped. The bundle was then printed at exit 0 without its <trace> map or
its sigs and bodies, and DEGRADED_PATH_ALERT is empty in Release, so nothing
said so. Measured on 109e7eb under INFRA_FAULT_MEMSTREAM_FINISH=1: 2,385
bytes at exit 0 against the control's 3,301, with no <trace> element.

Those blocks are the answer and have no second rendering, so the bundle is
refused the way --token-budget refuses its map. Both renderers return
std::optional, FromTraceResult carries isBufferLost, --from-trace and
--run-trace print a write error on stderr in every build and exit 1, and the
MCP from_trace verb answers -32603 instead of the no-frames error.

Gate: test/estchargecheck.sh #14f(g), in the next commit with the other
estchargecheck changes.

…m-trace arm

enumtablecheck: control() counted every violation in the mutated copy, so
one real violation in the tree turned all three positive controls red with
"the scan cannot see the defect it exists for", the wrong cause. It now
counts only the violations absent from the live scan. Proven on a copy with
tierHitCount put back to [3]: the rule arm fails, the enumerator control
reports its mutation did not take, and the other two controls pass, where
the old control() failed both.

estchargecheck #14f(g): --from-trace under the finish fault prints nothing
and exits 1 with the withheld line, against a control that prints its
<trace> bundle at exit 0. Red on 109e7eb (exit 0, no <trace> element).

estchargecheck #14g: (C) keyed closes on names assigned from a bare or rw::
opener, so `m = ::open_memstream(…)`, `os::` and `rw::os::` hid the close
while (A) still reported the open. The positive control now runs once per
spelling and names the hand-opened FILE* `hand`: (C)'s names are per file,
and tracelocus.h's other holders all say `m`, which let the old control pass
on a sibling's open. The old pattern misses (C) for three of the four.

quality.h's mirror note said ingest_cache.h includes it; it relies on
ingest.cpp's include order instead. CHANGELOG: the .pyi stub rule, the
metalfix row that already existed, what #14f asserts, and --from-trace's
refusal.

Takes #258, #260 and #261. No conflicts. The two files both sides touch are
CHANGELOG.md, where every entry is kept, and test/estchargecheck.sh, where
main re-points the alert-observability probe from --since=notadate (a refusal
since M8) to a --scip decode failure. This lane's #14f and #14g arms read the
same alerts_observable/ndebug_flavour pair and sit below the moved hunk, so
they run on the plain build and skip on an NDEBUG one exactly as before.

Takes train 2 (#265), #262 and #252. No conflicts: CHANGELOG.md keeps every
entry, and the lane's CONTRIBUTING, mcpverbs.h, quality.h and serialize.h
hunks sit apart from main's.

crashsweepcheck S2 counts raw open/fopen/open_memstream calls per enclosing
function against its registry, by name. MemoryStream::open() forwarded to its
own open(Opener&&) overload, which S2 read as a raw POSIX open in emit.h with
no registry row (red at 605ac9b: "infra/emit.h open: 1 raw open call(s),
registry says 0"). Registering it would have excused a call that opens
nothing, so the overload is renamed openWith; its one caller,
serialize.h's openChargeStream, follows. The S2 row and #14g's comment name it,
and #14g's opened-name pattern accepts `x.openWith(`.

Layer / File(s) Summary
Compile-time consistency fences
CMakeLists.txt, src/*.h, src/ingest.*, test/enumtablecheck.sh
The build now checks enum coverage, table extents, mask widths, serialized layouts, cache invariants, and enum-indexed arrays at compile time or link time. Owned C++ targets treat switch and implicit-fallthrough warnings as errors.
Language registration and classification
src/lintrules.h, src/ingest_crawl.h, src/resolve.h, src/nonlocalstate.h, src/main.cpp
Language token and extension tables are shared and cross-checked. .metal, .cu, .cuh, .pyi, and .phtml receive classifications. Python stubs with matching source files no longer duplicate nonlocal-state cells.
MemoryStream ownership and failure handling
src/infra/emit.h, src/serialize.h, src/main.cpp, src/mcp*.h, src/tracelocus.h, src/verbs_*.h
MemoryStream owns memory streams and reports incomplete writes. Serializers re-render or use modelled estimates, while budgeted, MCP, and trace outputs withhold incomplete results.
Validation and published counts
test/*.sh, .github/pargates-shard-weights.json, README.md, docs/EVALS.md, present/deck5_ripwire_build.js, CHANGELOG.md
New and updated gates cover enum tables, memory-stream ownership, language mappings, field mappings, and Python stubs. Published gate counts change from 621 to 622.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Resolve Python stub targets in Python Step-A.

resolvePythonImport checks only <module>.py and <module>/__init__.py through joinNormalizeLookup. A target that exists only as <module>.pyi or <module>/__init__.pyi therefore returns kNoFile, although .pyi importers are routed to this resolver and the dependency contract treats them as Python imports.

Probe the .pyi and __init__.pyi forms only after the .py candidates miss. Preserve the existing unique-or-degrade behavior for the selected candidates, and add fixture coverage for both stub-only forms.

…ith svLess

pythonStubsWithSource (4fd59d4) sorted a std::vector<std::string_view> and
binary-searched it with the default comparator, the shape that aborts the
Linux G1 leg inside libstdc++'s string_view::compare. portablebuildcheck #6b
named both calls on #272's CI (6 legs); its declaration scan run over this
tree reported exactly nonlocalstate.h:363 and :367, and reports nothing now.

…angTag too

7ece90b made langTag `inline constexpr`, and (N1)'s awk range only opened on
`inline const char* langTag(`, so it derived 0 tags and failed on #272's CI
(6 legs) with "the derivation broke". The range now accepts either spelling
and still derives from the switch, not a list.

Checked on copies of src/model.h: this tree derives 22 tags (main derives 22
too); a copy with one extra `return "zzlang";` row derives 23, zzlang among
them, so (N2) would demand its swatch; a copy whose langTag returns
std::string_view derives 0, and (N1) fails as it did on CI.

…ree's line numbers

This lane moves rankGraphTeleport four lines down src/graph.h, so the
published `--at=src/graph.h:3406` seed stopped resolving to it and
showcasecapturecheck (H) failed on #272's CI (6 legs).

The seeds are re-derived by the generator's own bodySeed (TELEPORT_LN 3410,
RANKGRAPH_LN 3451, DEFAULTMAP_LN 1505, MAIN_LN 3546), and the three sections
that carry them, `--at=src/graph.h:N`, `--callers=@src/graph.h:N` and
`--from-trace=-` (whose ASan fixture names all four), were re-run on a
committed tree (491ac9b) and rendered with the generator's own
publish_block, root/scratch neutralisation and export scrub. Every other
section is byte-identical, and none of the three reads a branch ref: the
diff carries no lane/ name. docs/COMMANDS.md regenerated from the capture:
the same two samples move, --check clean at 176 flags.

…ase capture's seed resolves again

3089304 spelled namespaceCompatible's default: as its four roles plus a
trailing return, four net lines above rankGraphTeleport. The 0.6.1 release
capture publishes `--at=src/graph.h:3406`, bodySeed's first body line with
zero slack, so the seed resolved to a refusal and showcasecapturecheck (H)
failed on #272's CI (6 legs).

A lane does not re-record the release capture (it scouts local branch
names, and the release PR owns it), so this reverts b8e86b9's re-splice
and keeps graph.h line-neutral instead: the four roles share one case line
and the doctrine paragraph above reflows from six lines to five. The
trailing return stays for GCC's -Wreturn-type. rankGraphTeleport's
signature is at 3404 on this tree and on main.

Takes #269, #270 and #271, merged with rerere off. CHANGELOG.md conflicted
only on adjacency under [Unreleased]: both sides' entries are kept, this
lane's first. src/graph.h, src/resolve.h and CONTRIBUTING.md merged clean,
and rankGraphTeleport's signature stays at main's line. The gate loop,
docs/gatecount_build.py (622, --check clean), the shard weights and
binoverridecheck's EXEMPT list merged without conflict and each still
names enumtablecheck once.

Disposition of the three red gates on c1ce76c (6 legs each). New head: 3e7d815 (pushed once).

  • portablebuildcheck #6b: pythonStubsWithSource (src/nonlocalstate.h) sorted and binary-searched a std::vector<std::string_view> with the default comparator. Both calls now pass rw::sortutil::svLess (843582f). The gate's own declaration scan named exactly those two lines and names nothing now.
  • htmlrendercheck (N1): langTag became inline constexpr, and the awk range only opened on inline const char* langTag(. It now accepts either spelling and still derives the tags from the switch (491ac9b). Checked on copies of model.h: this tree gives 22, an extra row gives 23, and a changed signature gives 0.
  • showcasecapturecheck (H): the release capture's --at=src/graph.h:3406 has zero slack, and this lane had added four lines above rankGraphTeleport. The capture is not re-recorded in a lane, so a re-splice (b8e86b9) is reverted and graph.h is line-neutral instead (41d2388). The seed signature is at 3404 on both this branch and main.
  • Merged origin/main ea03af8 with rerere off (3e7d815). CHANGELOG kept both sides, and the gate count (622), shard weights and EXEMPT list merged clean.

Local, --clean-first build (0 warnings), each gate run as its own script: htmlrendercheck, showcasecapturecheck, portablebuildcheck, manifestcheck, gateexitcheck, nonlocalstatecheck, nsfiltercheck, versioncheck, gatecountcheck, deckcheck, readmedriftcheck, docscommandscheck, printffmtparitycheck, limitstablecheck and langcensuscheck: 15/15 rc 0, 0 FAIL. gh pr view 272 --json mergeable: MERGEABLE.

includes it directly.

… an empty success

usesText turned a failed answer buffer (at the open, or a write lost inside
it) into "", and the live `uses` handler served that as a SUCCESS result
with empty text, which reads as an answer with no use sites (CodeRabbit on
#272). Measured on 3e7d815 under INFRA_FAULT_MEMSTREAM_FINISH=1: result
text of 0 bytes, no error.

usesText returns std::optional; nullopt makes the live handler answer
-32603 and the batch arm refuse the sub-request with the same internal
error. A complete buffer answers exactly as before, and count="0" stays a
valid answer. Gate: estchargecheck #14f(h), in the next commit.

… twice

When a --for block's charge buffer failed, the lens rendered the block again
straight to stdout, and both renderings added to the run's RedactCounts
(CodeRabbit on #272). Measured on 3e7d815 under
INFRA_FAULT_MEMSTREAM_FINISH=1 over a two-secret file: the stderr summary
said "redacted 4 secrets (aws-key=2 github-token=2)" for XML --for and for
--for --json, where the control says 2.

The JSON sigs block snapshots the tally before its buffered render and
restores it before the direct packSigs fallback. preRender (lego, compose,
routes, sigs) snapshots it on entry and restores it on both false returns.
A whole buffer keeps its counts.

Gates, red on 3e7d815 and added to estchargecheck #14f:
- (h) MCP uses answers -32603 under the fault (was a success with 0 bytes
  of text).
- (i) the redaction summary under the fault equals the control's, XML and
  --json (was 4 against 2).

…ead of an internal error

CodeRabbit on #277 (4036492159), on #272's memory-buffer fix. #272 taught
usesText, connectText and fromTraceText to report a buffer that lost bytes as
nullopt, answered -32603. Five more MCP answer builders still collapsed that
failure into an empty string: forTaskText, ownersText, exemplarText,
impactText and pathText (through `.value_or( std::string{} )`, or `return {};`
after the finish). Their dispatch sites read "" as the verb's not-found
answer, so a lost buffer was reported as "no symbols found", an unknown
symbol, "no matching exemplar" or an endpoint refusal, all -32602, which are
the caller's fault and not the server's.

The fix is the usesText shape, for all five:
- std::optional<std::string>, where nullopt is an unopenable or lost buffer
  and "" is still not-found;
- every not-found `return {};` becomes an explicit `return std::string{};`,
  because a bare `{}` would itself be nullopt once the return type is optional;
- the tools/call dispatch in src/mcp.h answers -32603 "internal error: the
  <verb> answer buffer lost bytes — no answer served" on nullopt;
- the batch arms in src/mcpverbs.h refuse with the same sentence.

Gate: estchargecheck #14f(h) was a uses-only arm and is now a matrix over
uses, impact, exemplar, path_between and for. With the fault off, each verb
must answer its element (<uses>, <impact>, <exemplar>, <path>, <ctx>) on
test/fixture; under INFRA_FAULT_MEMSTREAM_FINISH=1 each must answer -32603.
Green: 236 PASS, 0 FAIL. owners is not in the matrix: test/fixture's answer
depends on git history, and its builder is changed by the same mechanical
transform as the other four.

…witches

Train 1's #272 removed `default:` from dependencyCapable and dependencyDialect so an
appended Lang is a -Wswitch error; #233 was written against the defaulted switches and
relied on them to keep GDScript not dependency-capable (its PR: preload/load resolution is
a later round, and capability without edges would make dep_files= lie). The merged tree
failed -Werror=switch at lintrules.h:247/288. GDScript now joins Dart's explicit false /
DepDialect::None cases, with the reason in the DART paragraph.

The lane is three commits on top of redhat-et#251 (769003d, already in this train):
scan threads get a measured stack, and secret redaction is matched
structurally instead of through std::regex.

src/redact.h is the one conflict. redhat-et#272 (in this train) edited it too: it made
buildGenericClassTable, buildFirstByteRuleMask and both static tables
constexpr, and added the compile-time check that the hand-numbered first-byte
mask matches kRedactRules' order and first bytes. The lane kept kRedactRules,
each rule's pattern string, and the addRule mask shape, and replaced only the
matching engine. So the check still describes it, and the resolution is the
lane's file plus exactly redhat-et#272's changes:
- <limits> is kept, and the lane's removal of <regex> and <span> stands;
- the kCompiled regex array stays deleted (the lane);
- kGenericClass and kFirstByteMask are static constexpr (redhat-et#272);
- the old in-function size static_assert is gone, superseded by redhat-et#272's check
  beside the builder.
diff against 28a9173:src/redact.h shows nothing but redhat-et#272's lines, and the
file names std::regex only in the lane's own prose. The build is the proof
that the compile-time check holds over the lane's table.

…ne reason per group

quality-delta over the train range, merge-base with main..HEAD, gated on 6
rows after lane/input-blowup-guards @ 52a85cb cleared its own five. The
coordinator decided to ack these three groups. Each was acked through the
binary (--quality-delta=RANGE --quality-ack=REASON --ack-only=<symbol>), the
scope substring matched only that group's rows, and the ledger diff touches
exactly those six findings, keyed by symbol:
- redhat-et#272 emitForLensJson complexity 20 -> 25, a heal of key 38c814a4: the
  CodeRabbit-requested redaction-tally snapshot/restore on the buffered-render
  fallback (7f2ee21).
- reader-fuzzers appendPod, two new duplication and new-clone rows (69bea33d):
  the fuzz harness deliberately re-implements the on-disk writers so that it
  shares no code with the reader it attacks.
- redhat-et#244 jsLitCtorName (via train 2b), new rows 042afc2a and cc31469c plus a
  heal of 499d9f6f 59 -> 65: pairings with accessshape shapeName,
  namingconsistency styleTag and planlint glyphName that exist only on the
  merged tree; each side was acked on its own range.

src/ingest_crawl.h's kLangTable is the one table that decides whether the crawl looks at a file at all,
and it had rows for .h/.hpp/.hh but none for .hxx, so a tree that spells its headers .hxx was invisible
to the crawl (files=0, unindexed="hxx:N") even though six other per-extension tables in the tree
(flipimpact.h, layout.h, lintrules.h, quality.h x2, resolve.h, verbs_lint.h) already listed .hxx
alongside .hpp/.hh -- every downstream table was ready for an extension the crawl never admitted.

redhat-et#272 (dead .hxx row removal in two of those tables) has not reached this lane's base (fe28fd4); per the
lane brief, only the crawl table is touched here. The rows redhat-et#272 would make dead again are the six files
listed above -- re-add .hxx to whichever of them redhat-et#272 strips, once it lands.

.hxx now rides Lang::Cpp / tree-sitter-cpp, same as .h. kLangTable's std::array extent moves 48 -> 49 (an
exact count, not headroom, so a forgotten extent bump is a compile error). This changes extraction output
for any .hxx-bearing tree, so kParserVer moves 99 -> 100 (mirrored into quality.h's
kIngestParserVerMirror in this diff; test/qextractionkeycheck.sh asserts the equality), kQSnapCacheScheme
stays 14 (no cache key or blob-shape change, only extraction identity), and test/qschemetrip.hash is
re-pinned with a RE-PIN LOG entry.

test/filerootcheck.sh gained an arm: a .hxx file indexes as a single-file root (files=1, its own symbol
present, well-formed XML) -- the single-file branch runs through the same lookupLang(ext) table a
directory crawl does. Observed red on the pre-fix binary (files=0, unindexed="hxx:1") and green after.
