feat(ruby): class Child < Parent is an inheritance edge, so the lego view and the base walk answer for Ruby (parser version 99) by andriytyurnikov · Pull Request #325 · redhat-et/ripwire

andriytyurnikov · 2026-09-22T20:01:33Z

The gap

This is floor (a) from #267: Ruby feeds no class-hierarchy edges. class Child < Parent mints no IS-A edge today.

captureBases' clause table already matches Ruby's superclass node — Java spells its extends clause with the same
name. But isBaseTypeNode's list of base-TYPE node kinds holds nothing Ruby uses: a Ruby base is a (constant) —
class Child < Parent — or a (scope_resolution) — class Derived < Space::Base. So captureBases walked every
Ruby class header and emitted nothing, chaUp held no Ruby, and both consumers went hungry:

--lego reported implementors="0" on every Ruby corpus.
The resolver's base walk had nothing to walk. That walk is the probe Rule 1's implicit-self arm and Rules 2b/2c run
after a type's OWN method set misses, so Child.build stayed an honest split and a bare shared_helper inside
Child resolved to nothing.

The rule

Ruby's base node kinds are read under a language test rather than appended to the shared table. Both names are
generic enough to mean something else in another grammar, and that table is consulted for every base clause in every
language.
Only a direct (constant) / (scope_resolution) child is a base. captureBases descends one wrapper level for
TS's extends_clause and C#'s base_list, and for Ruby that descent could only land inside a computed superclass:
class Dynamic < Struct.new( :a ) emitted a base ref to the call's receiver, Struct. Ruby skips the descent.
A base is scoped by Ruby's own constant lookup, not by its final segment alone. The superclass as written is
resolved innermost-first along the enclosing Module.nesting, then at the top level (::X is absolute), against
every class and module the tree opens — namespace wrappers included. Only the classes that ARE that constant are its
base. No new extraction is involved: every class X < Y already records its written superclass as the symbolic
directive feat(ruby): constant references are dependencies — superclass, mixins and autoload, resolved through the corpus's own class/module index #57 emits, and resolve.h::RubyBaseScope joins the inherit ref to it through the derived class's open.
- 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.
- A base the tree never opens adds nothing to the CHA name graph, so its class's walk cannot reach an unrelated
  in-tree class of the same name.
Bases are read by constant (classesByFqn), not through byName. byName's 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. activerecord's Encryption::Errors::Base lost all six of its subclasses that way.
A class reopened with its superclass repeated is one implementor. Two opens of class Reop < Parent are two
symbols and one constant; the lego view lists the lowest-id symbol of that constant once.
A ref the join cannot place stays on the final-segment rule and is disclosed through DEGRADED_PATH_ALERT.

Measured, `--no-cache`, parser 97 → this branch

corpus	`--lego` implementors	edges	ambiguous
activerecord 8.1.3 `lib`, `--lego=active_record/base.rb:Base`	0 → 0	9,152 → 9,001	1,479 → 1,288
activerecord 8.1.3 `lib`, `--lego=active_record/encryption/errors.rb:Base`	0 → 6
activesupport 8.1.3 `lib`		3,912 → 3,915	434 → 422
actionpack 8.1.3 `lib`		3,140 → 3,127	364 → 355
Rails app A (private), `--lego=ApplicationRecord`	0 → 129	24,376 → 24,392	1,263 → 1,268
Rails app A, `app/controllers/application_controller.rb:ApplicationController`	0 → 114
Rails app A, `app/controllers/admin/application_controller.rb:ApplicationController`	0 → 19
Rails app B (private)		16,112 → 16,121	440 → 445

The before side was re-measured with a freshly built parser-97 binary. App B is a live repository, so its before
numbers differ from the ones published on #267. App A's ApplicationRecord was 130 before 5e1695d: one model was
counted twice, because a stub reopens it with the superclass repeated in a second file.

activerecord's Base is 0, and that is the right answer. No ActiveRecord::Base subclass lives in
activerecord's own lib. The final-segment key alone gave it 11, and every one was a collision: ActiveJob::Base,
the encryption errors' own Errors::Base, the generators' Base.
ambiguous falls on the gems because a two-way split collapses into one pinned edge. That is also why edges
falls: 151 fewer on activerecord are 151 calls that stopped naming two candidates.
ambiguous rises slightly on the apps, and that is the scoping removing wrong pins. 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.

No collateral movement. --deps is byte-identical on activerecord. The default map is byte-identical on four
Ruby-free corpora. This repository's --report totals are unchanged. There is no measurable time cost (app A:
0.83–0.87 s both ways).

Floors, each pinned by an arm of the gate

(a) 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. class Built < Factory.fabricate( :x ) against an in-tree Factory proves it.
(b) 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;. Ruby's ancestor chain really does hold
included modules, so this is a residue for a later round, not a claim that a mixin is not inheritance.
(c) The base walk's METHOD probe is still keyed by the immediate scope (Base::m). Two in-tree bases that share a
final name therefore share one probe: UsesAlpha.beta_make pins Beta::Base's method although
UsesAlpha < Alpha::Base. The implementor rows and the CHA edges are scoped; this probe is not yet.
(d) 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. It mints no class and no edge — the same decision as (a).
(e) A tags-query floor, not this round's: 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 decl/def collapse that dropped Encryption::Errors::Base affects all Ruby name resolution, not just bases. Only
the base path is fixed here; the rest deserves its own round.

Gate

test/rubyinheritcheck.sh reports 53/0, also under ASan. It was written red in three steps:

ddf3046, the inheritance edges: 18 passed and 11 failed against the pre-change binary. The claims are three
--lego implementor rows, Child.build and the two-level GrandChild.build reaching Parent::build,
Derived.make reaching Space::Base::make, a bare shared_helper inside Child reaching
Parent#shared_helper, and a mutation arm that drops the base clause and requires the pin to vanish with it.
63fd01b, the scoping: 11 failed and 36 passed against the parser-98 binary. The fixture gains Alpha::Base
and Beta::Base in their own files (so --lego=FILE:Base names one definition), a nested class Inner < Base,
an absolute class Abs < ::Parent, a namespace-wrapper base, a body-less base beside a bodied same-named one, and
Rec.make for the walk.
4f28412, after review: 51 passed and 2 failed against 5983cc5c. The claims are that a reopened class is
listed once and that implementors= counts distinct classes. The same commit pins floor (d).

The gate also pins determinism, warm == cold, xmllint, and a no-deletion floor (Mixed.new.helped keeps its ladder
edge). Every absence arm FAILs on a failed run rather than reading empty output as "no edge" (f0cc857, answering
CodeRabbit).

This change lifts #267's floor (a), so that arm of test/rubyrecvnarrowcheck.sh is inverted. It now asserts
Child.build pins to Parent::build, and it stands as the tripwire if Ruby ever loses its inheritance edges again.

Local battery (test/regression.sh, sequential, on the scoping commit): 653 pass, 3 fail.

versioncheck — a stale stamp; green after a rebuild.
nodekindcheck — two literal std::strcmps in the Ruby arm; fixed in 5983cc5.
showcasecapturecheck (H) — the graph.h edit moves the published seed off rankGraphTeleport. Left for the
capture regeneration on landing.

--quality-delta=b3270335..HEAD: gating=0, after 30a23d8 returned isBaseTypeNode to main's one-argument
signature (the Ruby kinds live in isBaseTypeNodeIn).

Versions and shared pins

kParserVer 97 → 99 in two steps, with kCacheVersion staying at 22:

98 (d5d0c89) adds records with the same layout: a Ruby cache written at 97 holds no inheritance refs.
99 (9a39e3c) removes records: a cache written at 98 holds the computed superclass's stray receiver ref.

Each step moves quality.h's mirror and re-pins test/qschemetrip.hash in the same commit. test/regression.sh
lists the gate, and the generated gate count moves 622 → 623.

The branch sits on the #267 commits as they landed in train 3 (#281). It has not been rebased onto today's main: the
only conflicts are the shared pins (the gate count in README.md, docs/EVALS.md, present/deck5_ripwire_build.js
and test/regression.sh), which I understand are re-derived on the merged tree.

…ors pinned `class Child < Parent` mints no IS-A edge today. captureBases' clause table already matches Ruby's `superclass` node (Java spells its extends clause with the same name), but isBaseTypeNode's list of base-TYPE node kinds holds nothing Ruby uses: a Ruby base is a (constant) — `class Child < Parent` — or a (scope_resolution) — `class Derived < Space::Base`. So no Ruby corpus has ever carried an inheritance edge: `--lego` lists no implementors, chaUp is empty, and the resolver's base walk (the probe Rule 1's implicit-self arm and Rules 2b/2c run after a type's OWN method set misses) has nothing to walk. That is floor (a) of test/rubyrecvnarrowcheck.sh, and it is what held the gem numbers down in that round: a gem reaches its class methods up an ActiveRecord::Base hierarchy. 18 arms pass and 11 fail against the current binary. The 11 are the claims: three --lego implementor rows (including a scope_resolution base named by its final segment), `Child.build` and the two-level `GrandChild.build` reaching Parent::build, `Derived.make` reaching Space::Base::make, a bare `shared_helper` inside Child reaching Parent#shared_helper (today it resolves to NOTHING — two same-named defs, no evidence, tier-3 declined), and the mutation arm that drops the base clause and requires the pin to vanish with it. Green already, and live: floor (a) a computed superclass (`class Dynamic < Struct.new( :a )`) is a call, not a constant; floor (b) 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 a real residue for a later round rather than a claim that it is not inheritance; floor (c) an out-of-tree base (`class Rec < ActiveRecord::Base`) mints no row. Plus determinism, warm == cold, xmllint, and a floor that deletes nothing (`Mixed.new.helped` keeps its ladder edge). test/regression.sh lists the gate; the generated gate count moves 622 -> 623.

…view and the base walk answer for Ruby isBaseTypeNode's table of base-TYPE node kinds held nothing Ruby uses. Ruby names a base with (constant) — `class Child < Parent` — or (scope_resolution) — `class Derived < Space::Base`. The CLAUSE was never the problem: `superclass` has been in captureBases' table since Java, whose extends clause carries the same node name. So captureBases walked every Ruby class header and emitted nothing, chaUp held no Ruby, and both consumers went hungry: --lego reported implementors="0" on every Ruby corpus, and the resolver's base walk — the probe Rule 1's implicit-self arm and Rules 2b/2c run after a type's OWN method set misses — had nothing to walk. The Ruby kinds are asked for under a language test rather than appended to the shared table: both names are generic enough to mean something else in another grammar, and that table is consulted for every base clause in every language. `class Dynamic < Struct.new( :a )` hands over a (call) and is correctly nothing. This lifts floor (a) of test/rubyrecvnarrowcheck.sh, which is why that gate's arm is INVERTED here (it now asserts Child.build pins to Parent::build, and stands as the tripwire if Ruby ever loses its inheritance edges again) and why the gem numbers in the constant-receiver round were the smallest: a gem reaches its class methods up an ActiveRecord::Base hierarchy. Measured, --no-cache, before -> after: activerecord lib --lego=Base 0 -> 11 implementors; edges 9152 -> 9001; ambiguous 1479 -> 1288 activesupport lib edges 3912 -> 3915; ambiguous 434 -> 422 actionpack lib edges 3140 -> 3127; ambiguous 364 -> 355 Rails app A --lego=ApplicationRecord 0 -> 130, --lego=ApplicationController 0 -> 132; edges 24376 -> 24390; ambiguous 1263 -> 1260 Rails app B edges 15257 -> 15301; ambiguous 451 -> 451 ambiguous falls because a two-way split collapses into one pinned edge, which is also why edges fall where they do: 151 fewer on activerecord is 151 calls that stopped naming two candidates. --deps byte-identical on activerecord; default map byte-identical on src/, npm, a Clojure project and CPython 3.14's stdlib; this repository's --report totals unchanged at 2053 files, 18985 symbols, 22529 edges. kParserVer 97 -> 98 (NEW records, same layout, kCacheVersion stays 22: a Ruby cache written at 97 holds no inheritance refs), quality.h's mirror with it, test/qschemetrip.hash re-pinned. Gate test/rubyinheritcheck.sh: 22 pass / 9 fail against the binary without this change, 31/0 with it. lego, cha, chacone, the eight other Ruby gates, clsrecv, narrow, narrowlang, resolve, resolverhonesty, decline, hasa, typeref, uses and reach are green.

… cache runs, and stops spelling a verdict on one line The same three fixes b327033 made to test/rubyrecvnarrowcheck.sh, applied to the gate this branch adds — before it reaches review carrying the defect its sibling was just asked to fix. No C++ moves. test/rubyinheritcheck.sh: ok() takes the house shape (test/nongitqmetricscheck.sh:9) — a failed write of the PASS line sets fail and says so in its own words. gateexitcheck's G1 arm names this contract, and the gate was failing it. The two --cache runs are exit-status checked, each with its own stderr file. The script carries set -u, not set -e: two runs that both failed and wrote the same bytes made cmp succeed, ok run, fail stay 0, and the cache arm report PASS. Ten verdicts spelled `… && ok … || no …` on one physical line are wrapped onto continuation lines (gateexitcheck's G2). test/rubyrecvnarrowcheck.sh: one more single-line verdict, at the --callers=Parent::build arm this branch's feature commit added to the file after b327033 wrapped the other eight. Mutation control for the cache arms — a wrapper that forwards to the real binary and exits 1 on a --cache argument, so the output is identical and cmp still matches: the gate now reports two FAILs and exits 1 where it printed ALL PASS before. gateexitcheck ALL PASS (G1 and G2 both green, 603 gates swept); rubyinheritcheck 30 arms ALL PASS; rubyrecvnarrowcheck 44 arms ALL PASS; manifestcheck clean.

…r (c) states the final-segment collision it was hiding CodeRabbit on redhat-et#325: the computed-superclass floor piped `--lego=Struct` through sed with stderr discarded, so a crashed binary's empty stdout read exactly like "no edge". Five arms had that shape — floors (a), (b) and (c), `--callers=Unrelated::build`, and the mutation's `--lego=Parent`. runq runs the binary in THIS shell (a $( ) capture would lose `no`'s fail=1 in a subshell) and FAILs a non-zero exit on its own line; each absence arm reads its output only when that returned 0. Closing the hole showed two of the arms had never been live. `--lego=Struct` and `--lego=ActiveRecord::Base` exit 1 with "type not found" — the fixture defines neither — so both passed on a refusal. For (a) that refusal is the right assertion and refuses() now pins it by its own message. For (c) it hid a false claim: a qualified base is keyed by its final segment (the byName convention every other language's bases use), so `class Rec < ActiveRecord::Base` lists as an implementor of the fixture's in-tree `Space::Base`. Floor (c) is restated to say that, and pinned both ways: the qualified name finds no type, and `--lego=Base` lists Rec. Telling the two Bases apart needs the Ruby constant index from redhat-et#57. The header comment and CHANGELOG.md say the same. No C++ moves. Crash control — a wrapper that exits 134 on each absence query: the gate reports those arms as FAILs and exits 1, where before the fix it printed PASS for them. rubyinheritcheck 32 arms ALL PASS; gateexitcheck and manifestcheck clean.

…ainst an in-tree receiver Floor (c) of test/rubyinheritcheck.sh said a qualified base is keyed by its final segment, so `class Rec < ActiveRecord::Base` listed as an implementor of the tree's own Space::Base and walked into its methods. The arms now say what the fix must do: a base is scoped by Ruby's own constant lookup (Module.nesting innermost first, then the top level, `::X` absolute) against every class/module the tree opens, wrappers included. Fixture: two more in-tree `Base`s (Alpha::Base in alpha.rb, Beta::Base in beta.rb, so --lego=FILE:Base names one definition), `class Inner < Base` inside module Beta, `class UsesAlpha < Alpha::Base`, `class Abs < ::Parent`, a namespace-wrapper base `class FromWrapper < Outer`, and `Rec.make` for the walk. The walk's METHOD probe stays keyed by the immediate scope, so `UsesAlpha.beta_make` still pins Beta::Base#beta_make — stated in the header and pinned, not claimed fixed. Floor (a) was passing for the wrong reason: captureBases' one-level wrapper descent lands on the receiver of a computed superclass, so `class Dynamic < Struct.new( :a )` mints an edge to `Struct` that read as absent only because the fixture defines no Struct. `class Built < Factory.fabricate( :x )` against an in-tree Factory pins it. Against the parser-98 binary (f0cc857): 11 fail, 36 pass.

…eiver captureBases descends one wrapper level under a base clause — TS's extends_clause, C#'s base_list — and did so for Ruby too. Ruby's `superclass` clause holds ONE expression with no wrapper, so the only thing that descent can reach is the inside of a COMPUTED superclass: `class Dynamic < Struct.new( :a )` landed on the call's receiver and emitted an inherit ref to `Struct`, and `class Built < Factory.fabricate( :x )` listed Built as an implementor of an in-tree Factory. The receiver is not the base. Ruby now reads a direct (constant)/(scope_resolution) child and nothing else. test/rubyinheritcheck.sh floor (a) passes both arms; the floor (c) scoping arms stay red until the next commit. kParserVer 98 -> 99 (FEWER records, same layout, kCacheVersion stays 22: a Ruby cache written at 98 holds the stray ref), quality.h's mirror with it, test/qschemetrip.hash re-pinned.

…ree Base lands on no in-tree Base A Ruby inherit ref is found by its final segment, the byName key every language's bases use, and that alone cannot tell `class Rec < ActiveRecord::Base` from the tree's own `Space::Base`: the out-of-tree base became an implementor of every in-tree `Base` AND fed the resolver's base walk, so a model's calls walked into an unrelated class's methods. resolve.h::RubyBaseScope scopes each one. No new extraction: every `class X < Y` already records its superclass AS WRITTEN as the symbolic directive redhat-et#57 emits at the class's start byte. The ref is joined to it through the derived class's open, and the written name is resolved as Ruby resolves it — innermost-first along the ENCLOSING nesting, then the top level, `::X` absolute — against every open the tree holds, namespace wrappers included (the redhat-et#57 definer table excludes wrappers and is the wrong oracle for "can a base name this"). buildGraph then: - lists as implementors only the classes whose own open IS that constant, read by constant (classesByFqn), not through byName: byName's 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 — activerecord's Encryption::Errors::Base lost all six subclasses that way; - adds no CHA edge for a base the tree never opens, so its class's walk stops there. A ref the join cannot place stays on the byName rule, disclosed through DEGRADED_PATH_ALERT. Floor still standing, pinned: the walk's METHOD probe is keyed `Scope::method` by the immediate scope, so two in-tree bases sharing a final name share one probe (`UsesAlpha.beta_make`). Measured, parser 97 (the PR's base) -> this commit; the CHANGELOG table is re-derived: activerecord lib base.rb:Base implementors 0 -> 0 (the 11 at 98 were all collisions); encryption/errors.rb:Base 0 -> 6; edges 9152 -> 9001; ambiguous 1479 -> 1288 activesupport lib edges 3912 -> 3915; ambiguous 434 -> 422 actionpack lib edges 3140 -> 3127; ambiguous 364 -> 355 Rails app A edges 24376 -> 24392; ambiguous 1263 -> 1268; ApplicationRecord 0 -> 130; ApplicationController 0 -> 114, Admin::ApplicationController 0 -> 19 Rails app B edges 16112 -> 16121; ambiguous 440 -> 445 Against 98 the gems' call graphs are unchanged; app A's only moved calls are two `self.data` sites that pinned a report handler's `data` through Reports::ResolutionHandlers::Base (now honest splits); app B's are twelve `polymorphic_name` sites split three ways over the app's own User/Organization/BankAccount ::Base (ActiveRecord answers them; they mint nothing now). --deps byte-identical on activerecord; the default map byte-identical on four Ruby-free corpora; this repository's --report totals unchanged. No measurable cost (app A wall time 0.83-0.87 s both ways). test/rubyinheritcheck.sh: 47 pass / 0 fail, and under ASan. The errs.rb arms (a body-less base beside a bodied same-named one) were added after the first cut of this change, when the activerecord measurement exposed the decl/def collapse; they fail against both the parser-98 binary and that first cut. --quality-delta: gating=0 (buildGraph +13 complexity, minor; buildRubyBaseScope 18 vs bar 15, new code).

… kindIs test/nodekindcheck.sh arm D requires every ingest walk section to be on kindIs with no literal std::strcmp left; the Ruby arm added in d5d0c89 introduced two. Same predicate, same output, no parser version change. Found by the full local battery.

63fd01bf test — red gate first: 11 fail / 36 pass against the parser-98 binary. Adds Alpha::Base / Beta::Base in their own files so --lego=FILE:Base names one definition, nested and absolute lookups, a namespace-wrapper base, and the base-walk case.
9a39e3c9 fix — class Dynamic < Struct.new( :a ) minted an inheritance edge to Struct: captureBases' one-level wrapper descent landed on the computed superclass's receiver. Floor (a) only read as passing because the fixture defines no Struct; class Built < Factory.fabricate( :x ) against an in-tree Factory now pins it. kParserVer 98 → 99 (fewer records, same layout), mirror and qschemetrip.hash in the same commit.
92c92271 fix — each Ruby base is scoped by Ruby's own constant lookup (enclosing Module.nesting innermost-first, then top level, ::X absolute) against every open the tree holds, joined through the superclass directive feat(ruby): constant references are dependencies — superclass, mixins and autoload, resolved through the corpus's own class/module index #57 already records — no extraction change. A base the tree never opens (ActiveRecord::Base) mints no implementor row and no CHA edge. Bases are read by constant, not through byName, because the C-family decl/def collapse drops a body-less class Base < StandardError; end next to any same-named class with a body.
5983cc5c refactor — the Ruby arm of isBaseTypeNode goes through kindIs; nodekindcheck arm D caught two literal std::strcmps from d5d0c894.

The published --lego=Base 0 → 11 on activerecord was all collisions (ActiveJob::Base, the encryption errors' own Errors::Base, the generators' Base); nothing in activerecord's lib subclasses ActiveRecord::Base, so it is 0 → 0 now, and encryption/errors.rb:Base is 0 → 6. The CHANGELOG table is re-derived against a freshly built parser-97 binary. Wrong pins removed on the apps: two self.data model calls pinned to a report handler through Reports::ResolutionHandlers::Base; twelve polymorphic_name sites split three ways over an app's own User::Base / Organization::Base / BankAccount::Base. On the gems the call graph is unchanged against 98. --deps is byte-identical on activerecord, the default map is byte-identical on four Ruby-free corpora, and this repo's --report totals are unchanged; no measurable time cost.

Local battery (test/regression.sh, sequential): 653 pass, 3 fail — versioncheck (stale stamp, green after rebuild), nodekindcheck (fixed in 5983cc5c), and showcasecapturecheck (H): the graph.h edit moves the published seed off rankGraphTeleport, left for the capture regeneration on landing. rubyinheritcheck 47/47, also under ASan.

Left for later rounds, stated in the gate: the base walk's method probe is keyed by the immediate scope (Base::m), so two in-tree bases sharing a final name still share one probe; and the decl/def collapse above affects all Ruby name resolution, not just bases — that one deserves its own round.

The conflicts with main are the shared pins; I have left them for the train.

joyful-ii-V-I

Thank you, @andriytyurnikov, and sorry for the wait. This is a strong PR. Scoping the base with Ruby's own constant lookup, rather than by final segment, is the right design. Re-deriving the activerecord numbers, and saying plainly that the old 0 → 11 was all collisions, is exactly the honesty we want in this repo. I merged the branch onto our current integration train, rebuilt it, and probed it with my own fixtures as well as yours.

A note on CI: your fork's workflow runs are waiting on maintainer approval, so CI has never run on this branch. A maintainer will approve the held run. The local results below are from our own build, not yours.

What I verified (on 5983cc5c merged onto integration/train-19, f84aceae)

The spellings. Each of these gets exactly the right --lego implementor: class Plain < Parent, class AbsKid < ::Parent, class ModKid < Mod::B (lands on Mod::B), and class InAlpha < Base inside module Alpha (lands on Alpha::Base, with nothing on Beta::Base).
Constant-lookup scoping, including one case your gate doesn't pin. class Outer::Inner::Compact < Base at the top level resolves to the top-level ::Base, and class Nested < Base written inside module Outer; module Inner resolves to Outer::Inner::Base. That is Ruby's real behaviour for compact nesting. class Orphan < Base with only namespaced Bases in scope reaches the top-level one and no other. class Rec < ActiveRecord::Base adds nothing anywhere.
Computed superclasses. class Dyn < Struct.new(:a, :b) adds no edge, and --lego=Struct reports "type not found".
The gate goes red when the feature is removed. rubyinheritcheck passes 49/49 on the merged tree. I made three mutants and it failed on each: the Ruby arm of isBaseTypeNode removed (14 FAIL), the Ruby no-descent guard removed so Struct.new descends again (3 FAIL, including the Factory.fabricate arm), and the scoping disabled so everything falls back to byName (13 FAIL, the Rec collision arms).
Cost. Ingest CPU time is unchanged on an 8.6k-file Ruby tree (Homebrew's Library/Homebrew, +0.0% min) and on ripwire's own tree (+0.7%, inside the noise).

Asks

must: DEGRADED_PATH_ALERT no longer exists on main. It was renamed to DISCLOSE in 52a4ad7, so the branch does not compile once merged. The rename alone is not enough, though. After it, selfcheckcheck fails arm R: "49 sink-less DISCLOSE( msg ) sites, pin 48". The one-argument form is a debug-only trace, so a release user is never told. This fallback does change the answer: the base goes back to the final-segment rule, which is the collision the PR exists to remove. So Diagnostics::answerUnchanged would not be honest here. Please pass a real sink, DISCLOSE( sink, why, "…" ), for example a count the graph or --lego output reports, the way #320 routes its unterminated fence through ExtractShortfall. Also update the comment above RubyBaseScope. test/selfcheckcheck.sh refuses the old name in any tracked file.
must: --quality-delta gates 1 with the current main binary. The finding is api-surface isBaseTypeNode at src/ingest_relations.h:24 (was=1 now=2), on both your own range and the merged range. The simplest fix is to keep the one-argument signature and add a separate isRubyBaseTypeNode( nt ) that captureBases checks under lang == Lang::Ruby. Alternatively, keep the change and record a reasoned ack with the range form (--quality-delta=<base>..HEAD --quality-ack="…") on the rebased tree. buildRubyBaseScope also sits at complexity 18 against a bar of 15. That one does not gate, but splitting out the reference loop would clear it.
must: the version and pin rebase below. This one is our trains' doing, not yours.
must (we can do it for you): the showcase seed. Please don't regenerate docs/captures/COMMANDS_showcase_2026-09-14.md. The recorder reads local branch and worktree state, so we correct that file by hand. The fix for check (H) is five lines: change src/graph.h:4009 to src/graph.h:4035 (four places), and on the <s n="rankGraphTeleport" …> row change l="4009" el="4037" to l="4035" el="4063". docs/COMMANDS.md is generated from that capture, so make the same three-line change there (--at=src/graph.h:4009 and the two l="4009" rows). With both edits, showcasecapturecheck and docscommandscheck pass on the merged tree.
should: state Class.new(Parent) as a floor. Built = Class.new(Parent) (with or without a block) adds no edge, although Ruby makes Built < Parent. That is a reasonable floor, but it isn't in your list of floors (a)–(d). One line in the CHANGELOG and an arm in the gate would make it explicit.
nice: a class reopened with a repeated superclass is listed twice. With class Reop < Parent … end written twice (a legal reopen), --lego=Parent lists Reop twice and reports implementors="4" for three classes. Either de-duplicate by constant or add a sentence to the disclosures.
nice (from reading the code, not tested): the lookup for a qualified base. rubyResolveBaseConstant looks up the whole written path along the nesting. So with Outer::Mod open and lacking a B, class X < Mod::B inside Outer falls through to a top-level Mod::B, where Ruby would raise NameError. This is rare in working code, and at most worth a comment.

Version and rebase steps. When train 19 (#332) merges, main will be at kParserVer 121 / kCacheVersion 25. #320 (Astro) is next and takes 122, so this PR becomes kParserVer 123, kCacheVersion 25. The inheritance refs use the existing Reference record, so the layout does not change and the cache version must not move. The merge conflicts in eight files:

CHANGELOG.md, README.md, docs/EVALS.md, present/deck5_ripwire_build.js, src/ingest_cache.h, src/quality.h, test/qschemetrip.hash and test/regression.sh: take main's side of each file.
src/ingest_cache.h: set kParserVer = 123 with one // 123 = … (#325, Ruby inheritance edges …) entry that folds in your 98 and 99 notes, above #320's 122. It should say "new records, same layout: kCacheVersion stays 25 (NOT 22/24)".
src/quality.h: set kIngestParserVerMirror = 123 with a one-line note, and leave kIngestCacheVersionMirror = 25. Drop the branch's stale "FOLLOW-UP … static_assert" comment, because that assert already exists on main.
test/qschemetripcheck.sh: add a RE-PIN LOG entry, "kParserVer -> 123 … kCacheVersion stays 25". Then UPDATE_GOLDEN=1 bash test/qschemetripcheck.sh build/ripwire must give 3250f2dc0c1ca4798555e6535d22ff45d76b043fe79ab02dd6dd38fdad4fd249. I checked that this is the same hash with and without #320 underneath.
test/regression.sh: keep main's absorb loop and add rubyinheritcheck in sorted order. Then python3 docs/gatecount_build.py rewrites README, docs/EVALS.md and the deck (650 once #320 is in, 649 without it).
CHANGELOG.md: put your "Ruby has inheritance edges" section back under ## [Unreleased]. Change its last sentence to "kParserVer 121 → 123 (carried as 97 → 99 on the PR) … kCacheVersion stays 25".
The DISCLOSE rename (with a sink) and the showcase and COMMANDS seed from the asks above.
The trap: don't take "theirs" for both ingest_cache.h and quality.h. That gives 99/22, which fails loudly, or, if you renumber only kParserVer, 123/22 or 123/24. That second case passes the mirror static_assert and builds green while silently reverting two cache-format bumps. If the pin in step 4 doesn't match, that is the sign.

On the merged tree, with the rename, the pins and the seed edits applied, the build has 0 warnings. 212 of the 214 gates that name a file you changed passed on the first run, including rubyinheritcheck, rubyrecvnarrowcheck, qschemetripcheck, gatecountcheck, nodekindcheck and formatgatecheck. The other two are the showcase/COMMANDS seed, which passes after the hand edit above, and selfcheckcheck, which waits on the sink.

How it lands. You're third in the parser-version queue, so this lands after train 19 and #320. Unless you'd rather do it yourself, we'll merge your branch into a later integration train and apply steps 1–8 in the merge commit. Your commits stay yours. We'd need a new commit from you only for the isBaseTypeNode signature (or its ack) and the Class.new floor line, though we're happy to carry those too, with credit, if you prefer. If you want to push the rebase, wait until #320 is on main and use the steps above.

Thanks again. Ruby answering --lego and the base walk is a real gain for Rails codebases, and the scoping work is what makes the numbers trustworthy.

…he Ruby kinds move to isBaseTypeNodeIn Review on redhat-et#325: --quality-delta gated 1 on `api-surface isBaseTypeNode (was=1 now=2)`, on the branch's own range and on the merged one. d5d0c89 had given the shared predicate a Lang parameter for Ruby's arm. isBaseTypeNode is byte-identical to main's again — the shared table and nothing else. The Ruby test lives in a new isBaseTypeNodeIn( nt, lang ), which answers Ruby's two node kinds, (constant) and (scope_resolution), under the language test and asks the shared table for every other language. captureBases' DIRECT arm calls it; the WRAPPED arm, which Ruby never reaches (it returns before the descent, 9a39e3c), calls isBaseTypeNode as it did before d5d0c89. Written as one conditional return rather than if/return/return: at that size the if form is a 38-token shape clone of mcpedit.h's redactionMarkerRefusalFor, and a split two-kindIs predicate is an 18-token clone of flipimpact.h's isCMakePath — both gating. Neither shape is a real duplicate; this one registers as none. Same predicate, same output, no parser version change. rubyinheritcheck and nodekindcheck ALL PASS.

…d) — Class.new( Parent ) — pinned Review on redhat-et#325, two asks: - nice: `class Reop < Parent … end` written twice (a legal reopen) is two symbols and one constant, and --lego=Parent listed Reop twice, reporting implementors="4" for three classes. Two arms: Reop is listed once, and implementors= counts DISTINCT classes (a row count alone agrees with the duplicate, so it would pass today). - should: `Built = Class.new( Parent )`, with or without a block, makes Built < Parent at runtime and mints no edge. That is the same decision as floor (a) — a base is read off a class header, never off a computed value — but it was not stated. It is floor (d) in the header now, with two arms. New fixture file reopen.rb, so no existing arm's counts move and the mutation arm (h.rb + caller.rb only) is untouched. Against 5983cc5's binary: 51 pass, 2 fail — the two reopen arms. Floor (d)'s arms are green, as a stated floor's are.

…mentor, not one per open Each open of `class Reop < Parent` is its own class symbol, so the implementor loop pushed two derived ids for one constant and --lego=Parent listed Reop twice (implementors="4" for three classes). RubyBaseScope::canonicalClass maps a Ruby derived class to the lowest-id symbol of its constant with its own kind — read through classesByFqn, the same by-constant table the base side already uses — and the loop's existing sort + unique collapses the reopen onto that one row. A symbol whose open is not indexed keeps its own id, so nothing that listed before stops listing. Other languages are untouched (the call is behind `lang == Lang::Ruby`), and the CHA name graph is keyed by name and never saw the duplicate. Measured against 5983cc5 built in a scratch worktree, the published --lego rows: activerecord base.rb:Base 0 and encryption/errors.rb:Base 6, app A's two ApplicationController rows 114 and 19 — all unchanged. App A's ApplicationRecord moves 130 -> 129, and the diff of the two implementor lists is exactly one row: a stub that reopens a top-level model `< ApplicationRecord` in a second file, the same constant as the model itself, counted twice before. The CHANGELOG table says 129 and why. CHANGELOG.md states floor (d), `Built = Class.new( Parent )`, beside the others, and the reopen. test/rubyinheritcheck.sh 53 pass / 0 fail (51/2 before), and under ASan, with rubyrecvnarrowcheck; ASan clean on activerecord and app A. Green: the other eight Ruby gates, lego, cha, chacone, nodekind, gateexit, manifest, qschemetrip, qextractionkey, resolve, resolverhonesty, narrow, clsrecv. App A's map deterministic across two runs and xmllint-clean. --quality-delta=b3270335..HEAD: gating=0. No parser version change: extraction is untouched, this is graph-time only.

Thank you for the thorough review. The mutants and the compact-nesting probe are exactly what I'd hoped someone would try.

Yes, please carry the rebase. Steps 1–8 in your train's merge commit, including the showcase/COMMANDS seed. I won't push a rebase.

Pushed three commits on top of 5983cc5c:

30a23d86 — isBaseTypeNode keeps main's one-argument signature. It is byte-identical to main's again. The Ruby kinds moved to a new isBaseTypeNodeIn( nt, lang ), which captureBases' direct arm calls; the wrapped arm calls isBaseTypeNode as before. --quality-delta=b3270335..HEAD now reports gating="0". I wrote it as one conditional return, because the if/return/return form and a separate two-kindIs predicate each register as gating shape clones of unrelated helpers (mcpedit.h::redactionMarkerRefusalFor, flipimpact.h::isCMakePath).
4f284126 (red first) + 5e1695d1 — a reopened class is one implementor. RubyBaseScope::canonicalClass maps a Ruby derived class to the lowest-id symbol of its constant, through classesByFqn, and the existing sort + unique collapses the reopen. One published number moves: app A's --lego=ApplicationRecord was 130 and is 129. I diffed the implementor lists against 5983cc5c built in a scratch worktree: the only difference is one model counted twice, because a stub reopens it with the superclass repeated in a second file. The CHANGELOG table says 129 and why. The other published rows (activerecord 0 and 6, app A 114 and 19) are unchanged.
Floor (d), Built = Class.new( Parent ), is stated in the gate header and the CHANGELOG, with two arms (with and without a block).

rubyinheritcheck passes 53/0 (51/2 before the fix), also under ASan together with rubyrecvnarrowcheck. ASan is clean on activerecord and app A. The other eight Ruby gates are green, as are lego, cha, chacone, nodekind, gateexit, manifest, qschemetrip, qextractionkey, resolve, resolverhonesty, narrow and clsrecv. There is no parser version change: these commits are graph-time only.

On the DISCLOSE sink — a proposal for you to accept or redirect. DISCLOSE isn't on this branch's base, so it can't compile here, and your recipe folds the rename into the merge commit. So here is the shape I'd suggest.

First, the fallback is defensive rather than common. It fires when a Ruby inherit ref has no superclass directive at its class open. A dev build (with the debug trace) never hit it on activerecord, activesupport, actionpack, both Rails apps or Ruby 4.0's own stdlib. Every class X < Y with a constant superclass records both facts from the same node.

Because it changes the answer (the base falls back to the final-segment rule), I'd put it on the graph gauge that --lego already carries, next to graph_ambiguous= / graph_unresolved=:

struct RubyBaseScopeDisclosure   // held by RubyBaseScope, copied onto the Graph
{
    enum class DisclosureWhy : std::uint8_t { NoSuperclassDirective };
    std::uint32_t unscoped = 0;   // Ruby bases left on the final-segment rule
    void disclose( DisclosureWhy ) noexcept { ++unscoped; }
};
// buildRubyBaseScope:
DISCLOSE( sc.disclosure, RubyBaseScopeDisclosure::DisclosureWhy::NoSuperclassDirective,
          "Ruby inherit reference with no superclass directive at its class open: base left on the byName rule" );

It would be emitted as ruby_bases_unscoped="N" by graphCountFloorAttrXml, only when N > 0, with one legend line. Every current output stays byte-identical, and the count reaches a release user whenever it happens. If you'd rather route it through an existing channel (a --report row, or --skipped the way #320 uses ExtractShortfall), I'm happy either way. Say which and I'll write it against the rebased tree, or you can carry it. I'll also update the comment above RubyBaseScope to match.

Not done in these commits:

buildRubyBaseScope is still at complexity 18 against a bar of 15. It doesn't gate, and splitting out the reference loop would clear it; I can do that in the same follow-up as the sink.
The qualified-lookup note (class X < Mod::B falling through to a top-level Mod::B where Ruby raises NameError) is not addressed yet. A comment at rubyResolveBaseConstant would be the honest minimum.

rubyScopeBaseReferences joins each Ruby inherit reference to the superclass directive at its class open. buildRubyBaseScope keeps the two index passes; its complexity drops under the bar of 15. No behavior change: rubyinheritcheck 53/0, app A --lego=ApplicationRecord still 129.

`class X < Mod::B` is looked up whole along the nesting, then at the top level. Ruby resolves only the first segment lexically, so where an enclosing Outer::Mod has no B, Ruby raises NameError while the lookup falls through to a top-level Mod::B. Comment only.

`export { x } from './y'`, `export * from './y'`, `export * as ns from './y'` and `export type { T } from './y'` load their module exactly as an import does, but directiveTargetOf had no export_statement branch, so no Include was recorded. A barrel file is made of nothing else: every edge out of an index.ts was missing from --deps/--arch/--impact/--report, and a cycle through a barrel read as acyclic with no disclosure, whatever the spelling (relative or through an alias). ingest_relations.h: export_statement (TS/JS) reads the grammar's `source:` field, as import_statement does; an export without one reads empty and the walk still descends into it. Stored ingest data changes, so kParserVer 122 -> 124 (123 stays reserved for #325), with quality.h's kIngestParserVerMirror in the same commit. kCacheVersion stays 25 (no record layout change); kQSnapCacheScheme stays 14. test/qschemetrip.hash re-derived with UPDATE_GOLDEN=1 (c451a79f1c…40c2cf), logged in the gate's RE-PIN LOG. depsprecisecheck (P2-O): a barrel with four export…from forms, relative and through `@/`: the barrel has 4 edges and a -> index -> b -> a is one 3-file cycle, nothing unresolved. The pre-124 binary finds no cycle in either tree. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

…edhat-et#339) Response to joyful-ii-V-I's review. The design change: schema columns are now DEFINITIONS ONLY. The "admission consequence" (columns reaching the call graph + PageRank) is retracted after the maintainer measured that untyped receivers bind unrelated calls to columns (`response.code` against a `code` column) and that a 200-table app's map was taken over by columns (196/200 rows; declines 292->1324). Columns still answer --uses/--grep/--whereis and appear in the map as defs. Required, all addressed: 1. Definitions-only: buildGraph/1d's byName fill skips SymKind::Section && Lang::Ruby (the same table feeds call binding AND common-name damping, so both consequences disappear at one seam, mirroring contextratio.h's isMeasurableKind). Gate §3 is now defs-only arms: callers=id -> defs=14 count=0, callers=created_at -> defs=2 count=0, a false-binding arm (a column-ONLY name, ref, gains no caller), and callers=name -> defs=19 count=3 (the METHOD/attr defs' edges only). model.h's sec comment is back to "no call edges"; CHANGELOG/tags.scm reworded. The ambiguity gauge drops 4 -> 2 (the id/created_at column sites left the gauge), pinned. 2. Shared walker instead of acking the duplication: captureRubyAttrDefs and captureRubySchemaDefs are now ONE pre-order walk (captureRubyDefs) dispatching both lanes per call node, with the per-file signals preserved (quality-delta duplication row must be gone — verified on the range, below). 3. Constraint floors: check_constraint / exclusion_constraint / unique_constraint added to kRubySchemaNonColumns — `t.check_constraint "price > 0", name: ...` no longer mints n="price > 0" (real dumps were measured); pinned by a fixture + undefinable arm. 4. kParserVer lands at 126 (123 is reserved for redhat-et#325, 124 in flight, 125 queued for redhat-et#338; the merge commit sets the final number). Mirror 126 in the same diff. 5. Version-stale "122" comments made number-free: tags.scm, the ingest_names.h lane header, model.h, rubyschemacheck.sh header, both .ripwire_quality_acks reasons. Optional, all addressed: composite/symbol primary_key now mints NO implicit id (an array-valued key has no id; the rendered columns are the block's own t.<type> lines) pinned by a composite-key fixture + arms, with the id defs=14 arm as the regression guard; spike_quote_single now spells t.string 'name' so the single-quote path is pinned; the lane header no longer claims "the container does not matter" (Gate 0 refuses class/module-nested tables); CHANGELOG "before" corrected to defs=10 (9 attr/def defs + the yaml key, per the maintainer's measurement). The lpin locality row is moot under definitions-only — answered on the review thread. Nice-to-have, all addressed: rubyFirstNonCommentArg's unused src parameter dropped; CHANGELOG floor lines for references/belongs_to (no <x>_id), create_join_table, and the Rails 8 queue_/cache_/cable_schema.rb content-match. Gate test/rubyschemacheck.sh: 39 arms, ALL PASS on build/ and asan/. Verification: determinism byte-identical + xmllint; full battery green (rubyattrscheck 47, rubysettercheck, manifest, loopconservation, gatecount, qschemetrip re-pinned, versioncheck, g1fresh, cachefuzz, qackorigin, qackconcurrency, ackonly); ASan + LSan sweep clean; quality-delta on the maintainer's range b343b98..HEAD: the captureRubyAttrDefs|captureRubySchemaDefs duplication row is GONE (shared walker) and gating=0 (verified after this commit). AI-assistance note: developed with AI assistance (DeepSeek V4 Flash and Qwen 3.8 Flash models) under the author's direct supervision; every change here was reviewed and verified by the author.

andriytyurnikov · 2026-09-27T13:49:23Z

Pushed two commits on top of 5e1695d1, closing the two items my last comment left open:

ba411270 — refactor. The reference join moves out of buildRubyBaseScope into rubyScopeBaseReferences. buildRubyBaseScope drops from complexity 18 to 8, and the new function is at 7, both under the bar of 15. No behavior change: rubyinheritcheck 53/0, and app A's --lego=ApplicationRecord is still 129.
5b455cdc — docs. A comment at rubyResolveBaseConstant states the qualified-lookup floor. class X < Mod::B is looked up whole along the nesting. Where an enclosing Outer::Mod has no B, Ruby raises NameError, but the lookup falls through to a top-level Mod::B. Comment only.

On a clean rebuild, rubyinheritcheck, rubyrecvnarrowcheck, lego, cha and nodekind all pass. --quality-delta=5e1695d1..HEAD reports 0 regressions and 0 gating. Both commits are graph-time only, so there is no parser version change.

Still open: the DISCLOSE sink. Can you say which channel you want: ruby_bases_unscoped="N" on the graph gauge as proposed, a --report row, or --skipped? One note for the merge: after ba411270, the one DEGRADED_PATH_ALERT site is in rubyScopeBaseReferences, not buildRubyBaseScope.

Queue: #332 and #336 have both landed, so this PR should be next. main is now at kParserVer 124, so the 123 and the qschemetrip hash in the recipe are from before train 20. I'll leave those for the train to work out.
