Integration train 1b lands train 2b plus seven more reviewed changes. Shared build products are resolved once and CI runs once. It supersedes #275 (train 2b), which went CONFLICTING after #264 merged; 2b's head be7871b is an ancestor of this branch unchanged, and it was green on all 34 checks on its own.

Member Head What it fixes
#275 train 2b: #243, #244 (@csy20), #256, field-final-segment be7871b explicit-template-argument calls; TS literal receivers; a class template's out-of-line member joins its class scope; field narrowing follow-up
#251 769003d a user's regex no longer aborts --graph-query/--arch; --match refuses a malformed pattern by name
#236 (@qinghuanandejiangshi) 1c6ebbf Python modules are no longer offered as runnable test scripts
#272 7f2ee21 compile-time checks for the tables, switches, masks and layouts that drifted silently; uses returns an error instead of an empty success on an incomplete buffer; redaction tally no longer double-counts on a buffered-render fallback
lane/regex-long-lines 28a9173 on Linux a --regex on a long line crashed (libstdc++ recursion). Literal/alternation fast paths byte-identical to std::regex, big-stack scan threads with ONE settled bound, and lines past the measured bound skipped and disclosed (regex_lines_skipped=, regex_line_max=, counts_floor); redaction no longer uses std::regex at all
lane/input-blowup-guards 52a85cb --for query terms deduped and capped at 1,024 unique terms with terms_capped/terms_total; MCP stdio request line bounded at 32 MiB with a named JSON-RPC error while the server keeps serving; --from-trace ASan parse is linear (160 KB: ~4 s → ~30 ms)
lane/hardened-checks 965d4ee a hazard-pattern gate; a 16-bit cache field that could wrap is refused; --with-profile parses with from_chars
lane/reader-fuzzers 8f6f86f 16 libFuzzer targets for the on-disk readers; a SCIP varint and a cache frame offset wrap fixed
CHANGELOG the held #261 and #271 entries

Every member was reviewed and signed off on its own before this train was built. Merges were done with rerere.enabled=false.

Shared products re-derived on the merged tree:

  • gate count 632 (docs/gatecount_build.py), the loop union, and shard weights from each lane's own entry
  • LIMITS 221 caps
  • kParserVer 102 and test/qschemetrip.hash 31d4ca8d, both carried from 2b (no 1b member changes extraction)
  • readWholeFile count re-derived with --uses (22)
  • hazardpatterncheck registry updated for the moved sites
  • the printf parity help_all re-recorded

Hand resolutions worth a look:

Quality-delta over fe28fd4..HEAD: gating 0. lane/input-blowup-guards fixed its own five rows. Six rows are acked through the binary, one reason per group:

Verification. Clean build, 0 warnings. Each gate was run as its own script, all rc 0:

  • the pin and count gates: manifestcheck, gateexitcheck, gatecountcheck, limits check, qextractionkeycheck, cppqualcheck
  • pincensuscheck, regexguardcheck, emittertruthcheck, compactlegendcheck
  • tracecheck, forblowupcheck, mcpstdiolinecapcheck
  • hazardpatterncheck, printffmtparitycheck, buildtypestampcheck, versioncheck, crashsweepcheck
  • determinism and xmllint

The local full suite was not run: the machine was contended, and this PR's full CI matrix is the suite.

Each member PR shows as merged once this lands.

…d no call reference

`r.get<K>( 1 )`, `p->get<K>( 1 )` and `x.template get<K>()` produced no reference at all. The callee
parses as call_expression function: (field_expression field: (template_method name: (field_identifier)))
and, behind the `template` keyword, field: (dependent_name (template_method ...)). No C++ reference
pattern bound either shape, so the drop happened at EXTRACTION, before ambiguous=/unresolved= could see
it. Measured 2026-09-16 on main 3bf884e: a four-line repro answered --callers=get count="0" beside
--callers=plain count="1"; --quality-delta reported a method reached only this way as dead-code.

The same family had two more wrong answers on the QUALIFIED dependent form, which did extract:
`X::template make<int>()` minted a reference NAMED `template make` (resolves to nothing), and
`X::template Rebind<int>::f()` keyed its qualifier as `template Rebind`, so the canonical tier missed and
the call split over a same-named definition in another scope.

Fix:
- queries/cpp/tags.scm: one alternation pattern binds both member shapes, @name on the field_identifier.
- src/ingest_binds.h: receiverOf reads calleeAccessParent, which steps over template_method and
  dependent_name to the field_expression. Without it `other.pick<int>()` classified as a BARE call and
  the enclosing-class rule bound it to the caller's own same-named method.
- src/ingest_names.h: skipTemplateDisambiguator (keyword plus whitespace/comments), applied to the
  qualifier inside immediateScope and to the name in cppResplitRefName — the H4 re-split block moved out
  of captureTagsFacts, whose complexity is measured; behaviour is unchanged for every other spelling.
- kParserVer 96 -> 99 and kIngestParserVerMirror -> 99 in the same commit (open PRs #235 hold 97/98 and
  #233 98 — next-free rule); kCacheVersion stays 22. test/qschemetrip.hash re-pinned via UPDATE_GOLDEN=1
  with a RE-PIN LOG line; kQSnapCacheScheme stays 12.

Measured effect (pre-fix vs fixed binary, this repo's src/, 169 files, --no-cache): references 168,457 ->
168,463, edges 18,308 -> 18,309, ambiguous=/unresolved= unchanged. The six references are exactly the
`r.pod<T>()` reads in src/gitoracle.h's loadOracleCache: --uses=pod 1 -> 7.

Gate: test/cppqualcheck.sh §12 with a new corpus test/cppqualtmplfix/member.cpp — one hand-read literal
per spelling (member dot/arrow, x.template, p->template, this->template, nested `>>` arguments, a chained
receiver, X::template, X::Y::template, a comment after the keyword), four controls the old patterns
already bound (free, qualified, non-type argument, 3-segment static), receiver/arity/qualifier decoys, the
fixture header, and a repo-root arm (--callers=pod names loadOracleCache).
- RED on the pre-fix binary: 19 of the 24 new checks FAIL (71 PASS / 19 FAIL); header edges=6 ambiguous=1.
- RED on a MUTATION build (three one-line reversions of the fix, 8 FAIL): the raw parent in receiverOf
  binds tqDecoyCaller to the decoy :110; an inert skipTemplateDisambiguator zeroes the three dependent
  --uses, fails the probe name arm and splits tqCallRebind; callArity's hop bound 4 -> 3 splits
  tqDepArityCaller. Reverted; the rebuilt binary is byte-identical to the fixed one.
- GREEN: 90/90 plain and ALL PASS under the ASan build; sanitizer-clean over the fixture, callformfix/cpp
  and src/.
test/callformcheck.sh row 11 (`b.template memberTmpl<int>()`) was documented-absent at literal 0 with a
probeBlind; it now pins 1 with a probeSees (red on the pre-fix binary: 2 FAIL).

Not fixed here, and routed around in the fixture rather than pinned (both on main already, both shared by
the plain member call): Rule 2 reads no PARAMETER type, so a call on a `Target&` parameter inside a class
with a same-named method binds the enclosing class; and a typed receiver splits over a same-class overload
set with no arity prune.

"x".replace() was captured as a bare replace(), so a unique export
function replace became a confident edge (graph_ambiguous=0). Decide
by the receiver's type instead: string/template/array/regex/number/
boolean literals, and chains that stay certain, skip the name ladder.
They bind only a matching Foo.prototype.NAME extension, else
vetoExternal.

isMemberAccessNode is unchanged for TS/JS. Object literals, this,
identifier receivers, casts, and find/at/pop/shift/reduce stay on
today's path.

kParserVer 96 -> 97 (append-only RecvKind, cache format unchanged).
…ser's regex, --match kept rows no predicate decided, and file() matched the checkout's directory name

Only --regex screened a user's pattern. `ripwire <dir> --graph-query='file(all,"(a+)+z")'` and an --arch rules
file with `deny path zz/.* -> (a+)+z` died with an uncaught std::regex_error on libc++ (rc 134) over a fixture
whose directory name is 44 'a'; --match swallowed the same throw and kept the row, and a malformed #match?
pattern kept every row, at rc 0. libstdc++ has no match budget, so each of these backtracks without end there.
--regex's own match-time throw skipped the file under an alert NDEBUG deletes and printed hits= as a count.
And file() matched ing.files verbatim, so file(all,"alpha") selected every symbol of a clone named repo_alpha
and none of repo_beta, and file(all,"^src/") selected nothing under an absolute root.

src/regexguard.h now owns the screen (moved verbatim from search.h), the compile and the match. It is the one
place in src/ that catches std::regex_error and std::bad_alloc, by type, and converts them to values
(RegexCompile's refusal, RegexVerdict::Exhausted) behind a noexcept API pinned by static_assert; no call site
holds a try. Every user-authored pattern goes through it: a refused pattern and an abandoned match both refuse
by name at exit 1 on --graph-query file(), --arch FROM/TO path-rules, --match and --lint-rules #match? (collected
through two opt-in AstQueryGroup outs), and --regex. The built-in lint packs keep the keep-the-row fallback for
their constant patterns. file() matches the root-relative path its p= prints, and decides each file once.

Byte-identical against the origin/main binary: 32/32 CLI comparisons over --grep/--regex, --graph-query, --arch,
--match, --lint, --lint-rules and the map, and a three-request --mcp grep session; the only differences are the
fixes. grepfastcheck (6) byte-identical to RIPWIRE_BASE on all 13 vectors. No compile added: once per query, rule
and grep worker as before.

Gate: test/regexguardcheck.sh (a) screen on five entry points with controls, (b1) RIPWIRE_FAULT_REGEX_MATCH=1
exhaustion on every standard library, (b2) (a|a)+z on libc++'s engine, (c) no std::regex outside the owner and a
two-row constant-table allowlist, (d) two clones agree. origin/main: 35 FAIL (four rc 134); this commit: 63 PASS.
All five registrations (regression.sh, gate count 618 -> 619, shard weight 14.8 s; binds RIPWIRE_BIN, so no
binoverride EXEMPT row). Pins moved: astqueryregexcheck C4 (a malformed --match pattern refuses) and its
golden's match-malformed section; printf_parity help_all (the --help file() clause); docs/COMMANDS.md regenerated.

--quality-delta=<merge-base>..HEAD: gating=0 after acking, through the binary, the two api-surface contract
changes (passesPredicates carries the user group's undecided counter; query::Eval takes the single-root prefix).
The ledger diff is one healed row (passesPredicates' existing P2-2 ack, 4 -> 5 params) and one new row. The two
new-symbol complexity rows are the screen moved verbatim from search.h.

…uestion it never finished — the seam, the byte-identical evidence and the gate

One ### Fixed entry: the reproduced rc-134 aborts (--graph-query file(), --arch path-rules), --match keeping rows
no predicate decided, --regex printing hits= over a file whose match the engine abandoned, file() matching the
checkout's directory name; src/regexguard.h as the one exception boundary behind a noexcept API; 32/32
byte-identical comparisons plus an --mcp session; test/regexguardcheck.sh red 35 / green 63.

…ntity with the template arguments in its scope

`template <class T> void Box<T>::grow() {}` minted `sc="Box<T>"` beside the in-class declaration's
`sc="Box"`, so one member was two identities: --callers=Box::grow resolved to the declaration and
answered count="0" while `use( Box<int>& b ) { b.grow(); }` sat in plain sight, with --impact and
--uses the same. qualifierOf and enclosingScopeOf read the scope node's TEXT, so a multi-line list put
its line break into the census id, and `Slot<std::string>` (a `::` inside the list) was cut by
immediateScope to `string>`. The reference side had the twin at two segments: `Factory<int>::make()`
qualified as `Factory<int>`, keyed nothing, and split onto an unrelated `Decoy::make`.

Fix: a scope tree-sitter hands over as a `template_type` keeps only its `name:` child
(cppScopeSegmentText), in the qualified declarator, a class specialization's name, and each link of a
qualified class name (cppScopeNameText, which returns the written text unchanged when no link is a
template). Structural, so nothing inside the list can unbalance it.

Decision: a specialization's member keys the PRIMARY template's member (`template<> void
Box<int>::grow()` is one more definition of Box::grow, joined like an overload). The resolver does no
template-argument deduction, so no call site can reach a `Box<int>` identity; the argument spelling is
not canonical; Rust `impl<T> Foo<T>` and the C++ 3-segment ref re-split already strip. The full
argument is in the gate header.

kParserVer 96 -> 100 with kIngestParserVerMirror (97..99 are held by open lanes #248/#244, #235/#233,
#243); kCacheVersion stays 22; qschemetrip re-pinned with a log entry. kMaxQualifierHops hoisted so the
two chain walkers share one cap (LIMITS.md unchanged at 212).

Measured (--pin-census, same corpus both binaries): dgl f0b7cc9, 343 C/C++/CUDA files — scope ids with
an argument list 156 -> 0; 77 of 32,628 decided sites change: 48 corrected targets + 1 wrong split
gone, 22 same id now split (primary + specialization both define the member: the join's cost,
disclosed as amb=), 6 mechanism label only; header edges 20,829 -> 20,745, ambiguous 1,891 -> 1,899.
This repo: 4 symbols move (dynamic_map.hpp node_rank specializations), no edge changes.

Gate: test/cpptmplscopecheck.sh (new, registered in regression.sh, shard weights, gate count 619).
Red on b1489df: 27 of 36 FAIL (the 9 passes are the control, presence guards, determinism and two
by-construction arms). Green: ALL PASS. Pin moved: test/stdqualcheck.sh §3 `hash<Mine>` -> `hash`
(fixture comment updated in place, line count unchanged).

Review on #244: refuse a Lit* call only when the name is a member of
that built-in type. Bind a JS Foo.prototype.NAME polyfill first;
otherwise External if the name exists in-repo, Undefined if it does
not. Names that are not members (shout, named-function proto,
Object.assign, declare global) keep today's ladder.

Stamp sc= only for String/Array/RegExp/Number/Boolean. Gate grows
number/boolean/join/charCodeAt arms, exact external=10, this.replace
pinned to user.ts:5, and a literal-corpus warm==cold check.
test/regression.sh: the gate loop is the UNION (diagnoticecheck from main, regexguardcheck from this lane); docs/gatecount_build.py rewrote 620. CHANGELOG: this lane's entry stays directly under [Unreleased], main's entries kept after it.

…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.

… 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)

… 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'

…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'

  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.

…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 its own substitution broke was silently inert, and a 20,000-byte --regex died in a 512 KiB grep worker

--arch: a TO template was only screened at parse, never parsed, so `deny path zz/(\w+)/.* -> (\1` was stored
and skipped on every edge (exit 0). It now compiles at parse with a placeholder atom in each \1..\9 ("x", then
"9" for an interval) and a template that compiles with neither rejects the rules file, naming it (CodeRabbit on
#251). A template that only breaks once an edge's captures are substituted — a{2,\1} becoming a{2,1}, invalid on
every standard library — used to leave the rule inert for that edge; pathRuleForbids now reports it (isRefused,
with the substituted text) and the verb refuses at exit 1 naming the rule, the edge and the text.

Stack: std::regex compiles by recursion. A standalone probe (compile + destroy one pattern, binary search for the
first signal death) measured the smallest crash at a 3,392-deep nesting, a 16,896-byte literal and 8,448
alternatives on Apple libc++'s 512 KiB std::thread stack, and at 960 deep / 3,648 bytes on a 512 KiB libstdc++ 13
thread (15,616 / 58,368 on its 8 MiB default). `--regex=<20,000 bytes>` passed the main thread's probe compile and
died with SIGBUS (rc 138) in a grep worker. The screen now refuses a pattern over 2,048 bytes or 64 nested groups
by name (both under every measured crash; the limit itself still compiles). Classified BOUNDARY in
docs/limits_classes.tsv; LIMITS.md and TUNING.md regenerated.

--lint-rules: the undecided-predicate refusal named only the rules directory; it now names the rule ids whose
queries carry a #match?/#not-match? predicate.

Gate test/regexguardcheck.sh (CodeRabbit on #251): the exhaustion contract is one helper for (b1) and (b2) — exit 1,
"abandoned the match", the pattern (or the --lint-rules rule id) named, no answer element on stdout, each a row.
New arms (e0)/(e) for the two --arch TO refusals and (g) for the bounds. Red on the e30fcc4 release binary:

…nd an engine throw would have ended wrap's noexcept scan

The scanner reads UNTRUSTED skill files, and its EXFILTRATE:net-exfil regex
(\b(curl|wget|nc)\b.*(\$VAR|base64))|((\$VAR|base64).*\b(curl|wget|nc)\b) was quadratic in the line: measured on
the release binary, a 20,000-byte fenced `curl curl …` line took 5.9 s and a 200,000-byte one was still running at
60 s. Every pattern also called std::regex directly, including hasTransmitVerb, which is noexcept, and the scan
behind wrap.h's noexcept wrapScanSkillDir — so a regex_error or bad_alloc from the engine would have terminated the
process.

net-exfil is now decided by hasNetExfilShape, one pass that keeps four positions per '\r'-free segment, derived
from the regex: `.` excludes '\n' and '\r'; a tool is a maximal [A-Za-z0-9_] run equal to curl/wget/nc; a var is
'$' + [A-Za-z_] (its shortest form) or the substring base64. Every other pattern (injection, the two remaining
exfil rules, frontmatter, scope-creep, the joined-body pass) compiles and matches through src/regexguard.h, and an
undecided match FAILS CLOSED: a CRITICAL SCAN-INCOMPLETE:regex-abandoned finding on that line, exit 2. The
regexguardcheck static arm's skillscan.h allowlist row is gone; redact.h is the one constant table left.

Gate test/regexguardcheck.sh arm (f): (f1) the linear decision agrees with an independent oracle (python re, `.`
spelled [^\r\n]) on 1,200 generated fenced lines, 184 positives — and the pre-change regex binary passes the same
arm, which is what validates the oracle; (f2) the 200,000-byte line scans clean within 20 s and a `$SECRET` at its
end is still caught; (f3) under RIPWIRE_FAULT_REGEX_MATCH=1 a clean file reports the CRITICAL scan-incomplete
finding at exit 2, and scans clean without it. Red on the e30fcc4 release binary: (f2) TIMEOUT; (c) 37 skillscan.h
sites once the row is removed. Byte-identical against origin/main 31e788c on --scan-skills over test/skillfix and
this repository's skills and --scan-skill over all ten fixtures.

byte-identical comparisons and the Release instructions-retired numbers. Per the coordinator's slot map it sits

… its low 16 bits and believed

The ingest cache writes five def fields (ppAlt, humps, deepLoc, ev, params) and a reference's argCount as
16-bit values in u32 slots, and readDef/readRef read them back with `std::uint16_t( r.u32() )`. The writer
never holds more than 16 bits there, so a larger value is corruption; the narrowing kept its low bits and
the record was served: a checksum-valid record carrying 0x10000 read as 0.

ByteR::u16Of32 refuses such a record the way enumU8 refuses an enum byte past its count: it folds into
`ok`, the record takes readFileRecord's one refusal path, that file reparses and the rest of the blob
stands. A debug-only alert names it, like its siblings.

Measured, cachefuzzcheck Part 3 fixture (15 files), three field classes (def.ppAlt, def.params,
ref.argCount), values 0x10000 and 0xFFFFFFFF with every recSum and the tableSum rebuilt:

…ite that is not there

parseProfTsv read the #PROF_TSV line column with std::atoi, which is undefined past INT_MAX. libc kept
the low 32 bits, so a line of 4294967329 (2^32 + 33) read as 33 and annotated the pointer-chase finding
at unfriendly.cpp:38 with a site that does not exist: heat_joined="1".

The column now goes through std::from_chars; a value that is not wholly a positive int in range is a
row that carries nothing joinable, skipped like the short row above it. No throwing parse, no UB.

withprofilecheck arm 8, red first: on the base the 2^32+33 row joined (heat_joined="1", 1 row carries
it); fixed, heat_joined="0". Its control, the same row at line 33, still joins, so the arm reads the
parse and not a missing file. withprofilecheck, lintcheck, lintrulescheck ALL PASS.

… src/, every site registered with why it is safe

Could this cycle's crashes have been caught before they shipped? Several of their shapes are visible in
source. crashsweepcheck holds three (a decoded count sizing an allocation, raw stream/descriptor opens,
thread bodies that may throw). hazardpatterncheck holds the rest, each run with ripwire's own --match
over src/ (19 queries, about 5 s) and re-read with comments and strings blanked:

  (A) an enum built from a byte reader outside ByteR::enumU8 — enum names derived from every
      enum_specifier (107), direct, static_cast, C-style and one-assignment-derived casts
  (B1) a catch handler that records nothing — no assignment, stored flag, returned value or emitted
      line — and one whose only statement is DEGRADED_PATH_ALERT (silent in every Release binary)
  (B2) a throw with no try around it in its own function
  (C) a throwing or overflow-undefined standard call where nothing may throw: std::sto*, .at( ),
      .value( ), the atoi family, std::filesystem without its error_code, a directory_entry query
      without one, a directory_iterator built without one, a range-for over a directory iterator
  (D) a decoded value narrowed into a smaller integer with no comparison on it first
  (E) a raw acquisition crashsweepcheck's S2 does not name — socket/accept/pipe/dup/kqueue, the malloc
      family, non-placement new, tree-sitter parsers/queries/cursors/trees — outside a type whose
      destructor releases it

Every registry row is (file, function, key, count, reason) and exact both ways: a new site, a moved
count, or a row that matches no site fails. Six rows are FINDINGs in files other lanes hold (five
catch handlers whose drop is silent in Release, for the disclosure lane; astQueryGrouped's empty
catch). Four are PENDING: the --eval-skills and `ripwire wrap` filesystem throws (exit 134 on a skills
tree holding an unreadable skill, reproduced here) that lane/crash-fixes-parsers already fixes; a
PENDING row that stops matching prints a NOTE asking for its deletion instead of failing, so the two
lanes land in either order (checked on a src copy carrying that branch's skilleval.h and wrap.h).

Red on the base (731d23b): C 6 sites (planlint's std::filesystem::absolute fallback, fixed here to
take an error_code; verbs_lint's atoi, fixed in the previous commit; the four PENDING), D 6 sites
(fixed two commits back). Green: A 1, B1 11 of 27 handlers, B2 3 of 5 throws, C 4 PENDING, D 0 of
1,269 casts, E 36 registered + 2 owned. Non-vacuity: a probe tree plants one violation and one
compliant twin per rule; exactly the 13 violations fire. A partial scan (engine cap) or a population
too small to be real FAILs, never reads as clean. A planted std::atoi in a src copy reds rule C.

Registered in test/regression.sh, the shard weights (5.2 s measured) and the generated gate count
(619 -> 620). gateexitcheck, manifestcheck, gatecountcheck, binoverridecheck, limitstablecheck,
pargatescheck, skipclassifycheck, ripwirepubliccheck, planlintcheck ALL PASS.

joyful-ii-V-I and others added 9 commits September 17, 2026 05:13
The lane is three commits on top of #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. #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 #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 (#272);
- the old in-function size static_assert is gone, superseded by #272's check
  beside the builder.
diff against 28a9173:src/redact.h shows nothing but #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.

At the coordinator's direction 1b now sits on train 2b (#243, #244, #256,
field-final-segment, plus 2b's own reconciles). When #275 merges, 1b's diff
against main shrinks to its own delta. Main 13a1916 was already in 1b.

Conflicts, all shared products:
- test/regression.sh: the loop is the union.
- README.md, docs/EVALS.md, deck5: gate-count markers only (630 vs 625). Main's
  side is kept here and the count is regenerated in the next commit.

Everything that merged clean without a textual conflict is re-derived on the
merged build in the commits that follow, not trusted: the ack ledger,
qschemetrip (2b 31d4ca8d), kParserVer (102), cppqualcheck's readWholeFile,
hazardpatterncheck's registry, printf_parity, LIMITS/TUNING and shard weights.

(regexguardcheck, hazardpatterncheck, forblowupcheck, mcpstdiolinecapcheck,
traceasanlinearcheck, enumtablecheck). LIMITS (221 caps) and TUNING are
unchanged by the 2b merge.

… in --version)

CHANGELOG.md: both sides added entries (2b's three C++ fixes vs #264's
--version entry); all kept, HEAD's first. test/regression.sh: the loop is the
union (adds buildtypestampcheck). The gate-count markers keep HEAD's side here
and are regenerated next.

…bosity bars)

Train 1b's quality-delta flagged three shapes this lane's own new code introduced,
gating=5 with no acks. Structure-only, byte-identical on every trace/MCP fixture checked:

- src/infra/stdinline.h: readByteSafeLine and readByteSafeLineBounded were a 113-token clone.
  Both are now one instantiation each of a shared readByteSafeLineCore<Bounded> template; the
  Bounded=false path carries no size check and no write to `overflowed` at all (if constexpr
  compiles the bounded branches out), so readByteSafeLine costs exactly what it did before --
  not a runtime branch on a sentinel maxBytes.
- src/tracein.h detail::parseAsan: complexity 8->21 (bar 15), verbosity 26->66 (bar 60). Split
  into computeAsanLocationInvariants (the once-per-line invariant derivation) and
  scanAsanWordBoundaries (the word-boundary walk), leaving parseAsan itself as the marker check
  + " in " split + two calls. Still linear -- the split is a call boundary, not new work.
- src/mcp.h runMcp: verbosity 54->63 (bar 60). Pulled the over-limit-line refusal into
  emitMcpStdioLineOverflowRefusal(); the loop's own over-limit branch is now two lines.

Verified byte-identical: built a from-scratch pre-refactor binary (56033b6) alongside this
one and diffed --from-trace on 4 fixtures (a demangled multi-word frame, a plain ASan trace, a
mixed python/asan/node/compiler trace, and the 2000-word pathological timing fixture) and one
normal + one 40 MB-oversized MCP stdio exchange -- all byte-identical.

…-delta fix over the earlier 56033b6 merge

No conflict. The lane's follow-up commit folds readByteSafeLine and its Bounded
clone into one readByteSafeLineCore<Bounded> template, splits parseAsan into
helpers, and extracts runMcp's refusal. That clears its own five gating rows:
the lane reports gating=0 on its own range, and it is re-checked on the merged
tree below.

…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:
- #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.
- #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.

…he merged tree no longer needs

On the merged train the gate reported "allow row search.h grepCollect excuses
nothing any more — delete the row". lane/regex-long-lines (28a9173) moved the
scan threads onto src/infra/stackthreads.h, so the bare-body exception is
gone. The table is now empty, with a comment in the same shape as S2's; S3
passes with no violation (19 PASS).

Walkthrough

Changes

The pull request adds guarded regex processing, owned memory-stream output, bounded input handling, compile-time consistency checks, parser and resolver fixes, reader fuzzing infrastructure, regression gates, and updated documentation.

Ripwire hardening and safeguards

Layer / File(s) Summary
Guarded regex and output handling
src/regexguard.h, src/search.h, src/arch.h, src/ingest_astquery.h, src/skillscan.h, src/infra/emit.h, src/serialize.h, src/tracelocus.h
User-authored regexes now pass through screening, guarded compilation, bounded matching, and explicit refusal or abandonment reporting. Memory streams own buffers and report incomplete writes before callers emit output.
Input and resource bounds
src/mcp.h, src/infra/stdinline.h, src/lexical.h, src/ingest_cache.h, src/scip.h, src/tracein.h
MCP request lines, query terms, serialized fields, varints, cache offsets, and ASan trace parsing receive explicit bounds or overflow handling.
Parser and resolution updates
queries/cpp/tags.scm, src/ingest_names.h, src/ingest_binds.h, src/resolve.h, src/graph.h, src/model.h
C++ member-template calls and template scopes gain extraction and canonical resolution support. TypeScript and JavaScript literal receivers receive built-in method classification. Qualified Rule 2b field narrowing reports final-segment provenance.
Build, fuzzing, and regression coverage
CMakeLists.txt, test/fuzz/readers/*, test/*check.sh, test/*harness.cpp
Compile-time fences, reader fuzz targets, generated seeds, mutation controls, static scans, differential harnesses, and regression checks cover the updated behavior. Documentation and generated counts are synchronized.

Inline comments:
In `@src/arch.h`:
- Around line 241-244: Update parseArchRules to stop rejecting templates solely
because compilation fails for the hardcoded "x" and "9" placeholder values;
retain only capture-independent syntax validation there, and defer
capture-dependent interval validation to the existing per-edge compilation in
pathRuleMatches.

In `@src/infra/stackthreads.h`:
- Line 104: Update the retry loop around the stack-thread startup logic so it
always attempts kStackThreadBytesFloor when the configured stackBytes is at
least that size, rather than allowing direct halving to skip the floor. Preserve
the existing retries above the floor and the caller fallback behavior when all
attempts fail.

In `@src/ingest_binds.h`:
- Around line 160-163: Update jsLiteralKindOf to classify unary_expression nodes
with unary + or - and a numeric argument as RecvKind::LitNumber, before the
fallback returning RecvKind::None. Preserve the existing direct number
classification and avoid treating other unary expressions as numeric receivers.

In `@src/ingest_names.h`:
- Around line 358-382: Update canonicalTemplateIdText to recognize and copy
character, string, and raw-string literals verbatim, applying whitespace
removal, comment detection, and comma spacing only outside literals. Preserve
literal contents such as /*, commas, and internal spacing so distinct
literal-valued structural specializations remain distinct; add regression
coverage for these cases.

In `@src/lexical.h`:
- Line 272: Rename uniqueSeenTotal and its documented/output consumers to
represent an occurrence upper bound, such as termsUpperBound, and emit it as
terms_upper_bound across all CLI and MCP surfaces instead of terms_total.
Preserve the maxUnique cap and existing kDroppedTerm scoring behavior, document
the bound semantics, and add a capped test covering repeated terms dropped after
the cap.

In `@src/mcpverbs.h`:
- Around line 2042-2047: Update forTaskText, ownersText, exemplarText,
impactText, and pathText to propagate mcpAnswerText(stream) failures instead of
converting them to empty strings, matching the optional/error-handling pattern
used by usesText and connectText. Update each corresponding dispatch site in
mcp.h to return an internal-error (-32603) response when the helper reports
failure, while preserving normal success responses for valid empty answers.

In `@src/query.h`:
- Around line 330-335: Update the RegexVerdict::Exhausted branch in filterFile()
to invoke DEGRADED_PATH_ALERT before fail(), matching the nearby compile-refusal
branch. Preserve the existing refusal message and return behavior.

In `@test/traceasanlinearcheck.sh`:
- Around line 127-139: Add a preflight requirement for the timeout utility
alongside the existing $BIN and python3 checks, and update timed_trace to treat
an execution failure such as exit status 127 as a test failure rather than
emitting a 1 ms sample; preserve normal timeout handling and valid elapsed-time
measurements.

…a); excuse it by an anchored directory row

CI on #277 (train 1b @ a954921) failed nulbytecheck on every leg that runs
it. The first was release (ubuntu-24.04, plain, gcc, shard 4/4), run
35216077780 job 105184771450: arm (a) reported "embedded NUL in
test/fuzz/readers/seeds/..." for 22 tracked files across nine reader
directories. lane/reader-fuzzers builds those seeds from the real binary
writers (make_seeds.sh) and adds minimized crash regressions, so NUL bytes are
the point. The files are extensionless because libFuzzer reads a directory, so
the gate's extension-only allowlist cannot name them.

The fix:
- One BINARY_DIRECTORIES row, test/fuzz/readers/seeds/, matched as a
  repo-relative path PREFIX ending in "/", never a substring.
- Arm (c) requires the directory row to hold at least one tracked file that
  really carries a NUL. It holds 54 files, 22 with a NUL; a directory whose
  binary files all left is a stale exemption.
- New arm (d) runs the same scanner from a scratch cwd. It plants
  test/fuzz/readers/seedsX/f, test/fuzz/readers/seeds_old/f and
  x/test/fuzz/readers/seeds/f with a NUL, and each must be FLAGGED. A control
  under test/fuzz/readers/seeds/ must be EXCUSED, or the three flags would pass
  for a scanner that excuses nothing.

Red first:
- a954921's gate gives rc=1 with the same 22 arm-(a) rows CI printed.
- A mutant that matches the row as a substring (`d in path`) turns arm (d) red
  on x/test/fuzz/readers/seeds/f.
Green: 13 PASS, 0 FAIL.

… so one gate failed every arm and the other passed on no measurement

Both gates ran the binary through `timeout N …`, and stock macOS ships no
timeout(1):
- mcpstdiolinecapcheck failed B1-B3 and C1-C2 on "timeout: command not found"
  (rc=127) on the macOS CI legs (#277, release macos-26 Release shard 3/4).
- traceasanlinearcheck read the same 127 as a TIMING SAMPLE. Every size "took"
  the few ms bash needs to report a missing command, arm B's ratios came out
  about 1x, and it passed without parsing a trace (CodeRabbit on #277, 4036492173).

The fix is test/lib/caprun.py, a capped runner built on subprocess.run's timeout
(no timeout(1)). It prints exactly one of "rc=N ms=M", "TIMEOUT ms=M" or
"EXECFAIL …", so a command that never started can never read as an exit status
or as a timing.
- Both gates gain arm (P). It proves the runner on the host before any arm
  trusts it: an exit status passes through (rc=3), the cap is enforced (a 5 s
  sleep under a 1 s cap), and a missing command is EXECFAIL.
- In mcpstdiolinecapcheck, B and C take their rc only from a completed run.
- In traceasanlinearcheck, a timing is a sample only for a completed rc=0 run.
  New arm B0 FAILs a run that did not complete, and B1-B3 compare real samples
  only, so a sentinel is never compared with itself and printed as a PASS.

Red first, with PATH=/usr/bin:/bin:/usr/sbin:/sbin (no timeout(1), like the CI
runner):
- a954921's mcpstdiolinecapcheck: rc=1, 6 FAIL, "timeout: command not found";
- a954921's traceasanlinearcheck: rc=0 PASS with 15/17/17/17 ms across
  40 KB .. 2.5 MB, which is the vacuous pass.
Control: an always-failing BIN makes the fixed trace gate rc=1, with 4 B0 FAIL
rows and 0 B PASS rows.
Green: mcpstdiolinecapcheck 10 PASS and traceasanlinearcheck 8 PASS, both with
Homebrew's timeout on PATH and without it.

… read as one symbol seen two ways

On #277 (train 1b) the gate failed on every leg that ran it, e.g.
release (ubuntu-24.04, Release, gcc, shard 3/4) and macos-26 Release shard 3/4,
with "internal inconsistency: ('readAckRecords', 'src/quality.h') is
tested=True from one seed and tested=False from another". Instrumented locally,
the two rows are different OVERLOADS: readAckRecords( path ) at quality.h:5267
(untested) and readAckRecords( path, badLines ) at :5273 (tested). The gate
keyed --impact rows by (name, file) after dropping the line, so the train's
reach change turned two honest answers into a false alarm. It reproduced on
two local runs of the same binary; it is not a flake.

The fix:
- The consistency check keys per DEFINITION, (name, file, line), through one
  observe() helper, so an inconsistency now means one definition read two ways.
- The set comparison with --test-gate stays over (name, file), because <u>
  carries no line. The projection counts a key as untested when ANY of its
  overloads is (exactly how <u> collapses them), and as tested only when ALL of
  them are (the complementary check). The dup_count disclosure is kept, and a
  key whose overloads disagree is printed as INFO.
- New OVERLOAD CONTROL feeds observe() planted rows: one definition seen tested
  and then untested must be flagged, and two same-named overloads with different
  tested= must not be.

Red first: a954921's gate gives rc=1 on the train binary, locally, twice.
Green: 19 PASS, with SET EQUALITY exact over 1000 rows and the mutation control
and overload control both passing.

…sed scan-thread stack skipped the 8 MiB floor

Two CodeRabbit findings on #277, both valid, both small. It also moves one gate
probe out of /tmp.

C7 (4036492163), src/query.h: file()'s compile-refusal branch raises
DEGRADED_PATH_ALERT before refusing, and the engine-abandonment branch refused
without one. Both branches refuse the query the same way, once per file()
call, so the abandonment branch now raises its own alert. regexguardcheck
(b1) asserts it on the fault-switch flavour, from the RIPWIRE_FAULT_REGEX_MATCH=1
file() run it already makes. The alert string does not exist in a954921's
source. Measured: stderr prints "[math degraded] query: file() regex match
abandoned by the engine — empty result".

C2 (4036492093), src/infra/stackthreads.h: a refused stack try retried with
plain halving and stopped below the floor, so a request that is not a
power-of-two multiple of 8 MiB (12 MiB -> 6 MiB) never tried the 8 MiB floor
before falling back to the caller's stack. The step is now
nextStackTryBytes(): half, but never past the floor; the floor itself is
always the last try; a request below the floor is tried once. Four
static_asserts pin it (12 MiB -> 8 MiB, 8 MiB -> stop, 256 MiB -> 128 MiB,
4 MiB -> stop), so the compiler proves it on every build. No gate arm was
added, because no fault hook reaches the case: the one shipped request is
kGrepScanStackBytes (256 MiB), which halves exactly onto the floor, and
RIPWIRE_FAULT_SCAN_STACK_MIXED refuses only sizes above half the request.
regexguardcheck (n) still exercises the loop and passes.

test/mcpstdiolinecapcheck.sh: its RSS probe wrote
/tmp/mcpstdiolinecapcheck_probe.txt, outside the gate's mktemp dir. It now
writes under $TMP (independent triage of #277).

Gates: regexguardcheck 132 PASS, mcpstdiolinecapcheck 10 PASS.

…teral and could bind an unrelated toFixed

A maintainer fix on contributor code: #244 (@csy20, TS/JS literal receivers,
carried by train 2b), from CodeRabbit on #277 (4036492136).

The grammar spells the sign of a numeric literal as a unary_expression over a
`number` node. classifyJsTsLiteralRecv unwrapped parentheses but not the sign,
so (-1).toFixed() and (+2).toFixed() classified as RecvKind::None, and the
call fell back to the name ladder and bound the in-repo `toFixed` #244's own
fixture plants beside it. A unary + or - over a number now classifies as
LitNumber; every other unary expression (!1, typeof 1, -x) stays unclassified.

This is an extraction change, so kParserVer moves 102 -> 103 with
quality.h's kIngestParserVerMirror (qextractionkeycheck 15 PASS). The qsnap
scheme does not move: the snapshot layout is unchanged. test/qschemetrip.hash
is re-pinned through UPDATE_GOLDEN=1 (95a27416), with the reason in the
gate's RE-PIN LOG.

Gate: test/fieldnarrowcheck.sh's literal-receiver arm gains viaNegative and
viaPositive in its TS, JS and TSX fixtures. They join the presence guard and
the no-edge-into-unrelated loop, and each corpus's exact external= rises from
10 to 12.
Red on the pre-fix binary: rc=1, 10 FAIL (external=10 on all three corpora,
and viaNegative/viaPositive "still binds unrelated" in each).
Green: 94 PASS, 0 FAIL.

…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.

…pped query's "distinct" total was an occurrence count

CodeRabbit on #277 (4036492152), on lane/input-blowup-guards. Past
kMaxUniqueQueryTerms (1024), dedupeQueryTerms looked each token up in the
KEPT terms only. A repeat of a spelling the cap had dropped missed that
lookup and incremented uniqueSeenTotal again, so terms_total, disclosed on the
CLI --for root and the MCP for/pack_task answers, read as a distinct total
while counting post-cap occurrences.

The fix counts exactly, instead of renaming the attribute to a bound. The
dropped spellings go into an ankerl::unordered_dense::set of string_views into
qToks, and a dropped spelling counts only the first time it is seen.
- Memory: never more entries than the query has tokens, and no copy, so
  nothing beyond the input already held.
- Time: O(1) per dropped token; the kept-terms scan stays bounded by maxUnique.
- The scores are unchanged: dropped terms still map to kDroppedTerm.
- terms_total keeps its name and its documented meaning (every distinct term the
  query contained), so no legend, pin or CLI/MCP spelling moves.

Gate: forblowupcheck gains C3: 1026 distinct terms, then the two dropped
spellings repeated 40 more times each, and terms_total must be 1026. The gate's
A0 stderr capture also moves from /tmp/forblowupcheck_a.err to its mktemp dir.
Red on the pre-fix binary: C3 terms_total='1106' (1024 kept plus every post-cap
occurrence).
Green: 11 PASS, with A3 5000 and C2 1025 unchanged.

…ons move up one

Train 1b's fix push bumps kParserVer 102 -> 103 (a signed numeric literal receiver,
`(-1).toFixed()`), so every train 3 assignment moves up one in merge order: #276 = 104,
small-fixes = 105, #278 = 106, #235 = 107, #233 = 108, #267 = 109.
- src/ingest_cache.h, src/quality.h: kParserVer and its mirror 109; every train 3 note
  renumbered; 1b's 103, which its push recorded only in the RE-PIN LOG, gains a note in both
  headers; kCacheVersion's note names #278's parser version 106.
- test/qschemetripcheck.sh: the TRAIN 3 entry names 1b's fix push and the new numbers, the
  member entries are renumbered, and 1b's own entry follows them.
- test/qschemetrip.hash: re-derived on this merged tree (neither side's pin hashed 109).
- CHANGELOG.md: the train 3 entries' parser-version sentences and headings renumbered.
Everything else in the fix push (MCP builders, --for terms_total, regex alerts, the
impactpartition/nulbyte/timeout gate fixes) merged without conflict.

…sy20)

Trains 2b and 1b carried #244 without an entry. Written from the PR's description (the rule,
its scope, the webpack/node/zod census) and fb0f667 (a signed number literal, from CodeRabbit
on #277), placed before #268's entry so the train entries stay in landing order, with its
parser versions (100 on train 2b, 103 on train 1b) and @csy20's credit.

… a real capture made it valid

deny path FROM -> TO validated a TO template like a{10,\1} by compiling it once with a placeholder
in \1's place, trying "x" then "9" and rejecting the whole rules file only when both failed. "x" is
not a digit, so it fails ANY numeric-interval position on that alone ({10,x}) regardless of the
template; a{10,\1} failed both ({10,x} non-numeric, {10,9} since 9<10) and was refused outright even
though \1="20" makes {10,20} perfectly valid (CodeRabbit review on redhat-et#277).

The probe is now a single "9" (valid everywhere a placeholder can sit: literal text, or a genuine
interval digit), and a refusal is accepted at parse time only when it is NOT
std::regex_constants::error_badbrace -- an out-of-order {min,max} is a fact about which digits a
specific capture supplies, not about the template's structure, so it defers to the edge:
pathRuleMatches already compiles the real substitution per edge and refuses by name only the edges
whose own capture is actually invalid.

RegexCompile gained isIntervalRangeOnly, set once at the std::regex_error catch site
compileGuardedRegex already had -- no new file spells std::regex (regexguardcheck.sh arm (c), which
caught the first version of this fix routing the check through a second parse in arch.h itself).

Gate: test/archcheck.sh new F-H9 section -- a valid capture applies (a real verdict, not a
parse-time refusal), an invalid capture refuses that edge by name, and a template broken independent
of any capture still refuses at parse time, unchanged.

…ase-reexport

Three adjacent-insertion conflicts, both sides kept: CHANGELOG.md (this lane's entry above
train 1b's), src/resolve.h (buildUsingReexports beside localityRank/appendTemplateFamilyKey;
one namesplit.h include, both uses named), test/fieldnarrowcheck.sh (the (u) arms, then main's
(r) arms and its rewritten TS/JS literal-receiver section; the stale KNOWN GAP header dropped,
the (h) gauge no longer quoted by number).
