Issue #62 stopped serving CALL sites from preprocessor-dead ranges. It left every other role serving them.

A role="write" inside #if 0 is a write that cannot compile, and --uses counted it:

# c.cpp: liveWrite does `o.field = 1;`  ·  deadWrite does `o.field = 2;` inside `#if 0`
<uses of="Owner.field" count="4" … counts_floor="1">     <- truth is 2

A count carrying counts_floor="1" must never exceed the truth, so this is the contract's own failure
direction, not a cosmetic one.

Six roles, red first

test/ppdeadrolescheck.sh was written and run against the unmodified main binary before any code changed:

role base after
call PASS — #62 already correct PASS
macro PASS — a retag of Call, so it inherited #62's drop PASS
read / write FAIL PASS
--uses floor FAIL count="4", truth 2 PASS count="2"
import, using ns::x; PASS PASS
import, #include FAIL PASS
extends FAIL PASS
type FAIL PASS
#else of #if 1 / of #if 0 FAIL both PASS
dead definitions FAIL ×7 PASS
var→type bindings FAIL PASS

Two of those were not on the list this started from. #include is a second, independent emitter of
role="import"
, living in captureIncludes rather than the tags arm, which #62 never touched. And the
P2-D Foo x; bindings: a Bar x; inside #if 0 above a live Foo x; gave x.m() an amb="1" and two
prov="split" edges, where deleting the block outright resolves it to one. That arm is gated against the
dead-block-deleted file as its control.

Dead definitions are excluded too, and the cost is measured

A definition inside #if 0 was still indexed and still a resolution target, so amb=, prov="split" and
overloads= were being minted by code that cannot compile — degrading the trust calibration the tool sells
("read the source if which-target matters"). Excluding them was the more invasive of the two options, so it
had to earn it:

  • llvm-project (8,861 C-family files, 381,811 symbols): −14 symbols, +3 edges, −16 declined.
    ambiguous, unresolved, est_tokens, extent_suspect_syms and the unindexed roll-up are all
    unchanged. Every dropped row is a real #if 0 definition — LoopSimplify.cpp's verifyLoop, and the
    five in Descriptor.cpp that LLVM itself comments as "not needed… leaving it here for now", whose names
    were minting overloads="2" against a live macro.
  • ripwire's own map is byte-identical to base.
  • User CPU 59.1 s vs 59.4 s on llvm, interleaved — no regression.

The honest cost: --grep is unchanged (text inside #if 0 is still findable, hit rows byte-identical), but
--expand=deadType now refuses with matched no symbol (did you mean 'deadDep'?) — a refusal carrying a
suggestion rather than a silent zero, and the old answer there was poor anyway, the dead def's span having
swallowed most of the file.

One rule, asked once

This does not add five more continues beside the existing one. The question is asked once per file and
answered once per record, as a post-pass over the window each capture driver appended, keyed on the record's
own site byte. A second spelling of "which lines of this file exist" is worse than the usual echo-site
drift, because the copies can disagree about the file itself. The call and import rows that drop are
byte-for-byte the ones that dropped before — a reference is sited at the same startByte either way — so
the half that was already correct is undisturbed. Ranges are walked once per file in the parse-pool worker
and ride PendingParsedFile to the deferred tags pass, so no C-family header pays for them twice.

Versions

kParserVer 93 → 94 and its quality.h mirror. kCacheVersion stays 21: it is a record-shape lever,
and no record gains or loses a field here — only which records are extracted. loadCache returns empty on a
"version-or-parserVer mismatch", so the parser bump alone rejects every v0.6.0 blob.
qschemetrip.hash re-pinned; qextractionkeycheck needed no edit (it reads the live constants:
scheme=10 cacheVer=21 parserVer=94).

A residual, disclosed rather than left to be found

BindingAlias (the FFI aliases) carries no site byte, so an extern "C" block inside #if 0 still
contributes its aliases. Giving it one is a record-shape change — a kCacheVersion bump this defect does
not earn, since an alias whose target has no live definition mints no edge, and one whose target is live
names a symbol that really is indexed. Stated beside bindSiteByte and in the gate header. Likewise the L3
fn-pointer clobber sweep reads its own context state: a clobber inside a dead range can still suppress a
live edge, which under-reports — the floor the tool already publishes.

Verification

617 gates: 615 pass, 2 skip, 0 fail (tree_writes=0). Warm == cold proved byte-identical across 6 corpora
with dead ranges through a private cache home, with a guard that a cache record was really written —
otherwise the warm side is a second cold parse and the arm degrades into the determinism gate. Determinism
×3 byte-identical, xmllint clean, ASan/UBSan clean on the tree and on the new path, gatecount_build --check and limits_build --check green.

🤖 Generated with Claude Code

Updated after merging main: #139 took parser version 93 and cache format 21, so this lands on 94 and keeps 21.

…other role

#62 dropped a reference captured inside a preprocessor-decided-dead range, but the
`continue` that did it sat inside captureTagsFacts' @reference.call / @reference.import
arm — so it covered two of the seven roles --uses publishes and none of the passes that
run their own walk. A value read, an assignment target, a bare type mention, a base
clause, the import site an `#include` directive mints and the blanked member-macro use
were all still served from source that cannot compile: --uses=Owner.field answered
count="4" on a fixture whose truth is 2, under a root carrying counts_floor="1". A floor
that over-counts is a wrong answer, not a noisy one.

The definitions were worse, because nothing downstream could tell. One `dup` defined
inside `#if 0` and one live left the single caller with amb="1", two prov="split" edges,
overloads="2" on the survivor and graph_ambiguous="1" on the <callers> root — four claims
of ambiguity where the source admits one candidate, degrading exactly the trust
calibration the tool sells ("read the source if which-target matters"). LLVM has this for
real: clang's Descriptor.cpp keeps five functions inside an `#if 0` it documents as "not
needed", and their names were minting overloads="2" on a live macro. The same shape
reached receiver narrowing through the local var→type bindings — a `Bar x;` inside
`#if 0` above a live `Foo x;` split `x.m()` across both methods, where deleting the dead
block outright resolves it to one.

So the rule is asked once per file and answered once per record: a post-pass over the
window each capture driver appended, keyed on the record's own site byte. One spelling,
not six — preprocdead.h's own header says what a second answer to "which lines of this
file exist" costs here. A definition is sited at its NAME, so a live function whose body
holds an `#if 0` block keeps its row and only the facts spelled inside the block go.

Measured on llvm-project (8,861 C-family files, 381,811 symbols): 14 symbols dropped, 3
edges gained, 16 fewer declined; ambiguous, unresolved, est_tokens and the unindexed
roll-up unchanged; user CPU 59.1 s against the base's 59.4 s, interleaved. ripwire's own
map is byte-identical, because nothing it crawls carries a decided-dead range.

The extracted set changes, so kParserVer 92 -> 93 and quality.h's mirror with it; record
shapes do not, so kCacheVersion stays 20. The FFI aliases keep no site byte and so keep
their dead-range rows — giving them one is a record-shape change the defect does not
earn, and it is disclosed beside bindSiteByte and in the gate's header rather than left
to be rediscovered.

…deadrolescheck

Eight marked sites across three files said 602 while test/regression.sh's absorb loop
names 603. Regenerated by docs/gatecount_build.py, which is the whole point of the number
being a build product: two lanes adding a gate each cannot agree on a stale figure.

Kept out of the fix commit on purpose — several lanes are adding gates at once, so this
is the one hunk that will conflict at landing, and re-running the generator over the
unioned loop is the documented resolution.

… ripwire exited 0

Both of the gate's ripwire invokers discarded the exit status — run() for the thirteen
cold answers, warm() for the sixteen cache runs — so every arm in the file read a
document without ever establishing that the run which wrote it finished. Nothing
downstream can see that: `--uses` output looks the same either way, and the live-row /
dead-row arms are string checks over whatever bytes are there. CONTRIBUTING.md §2's
recurring failure mode, reached from the input side.

Measured, not argued. Against a `ripwire` that emits the real answer byte for byte and
then exits 3, the gate as it stood printed 32 PASS and exited 0 — a full green verdict
on a binary that failed all 29 invocations. With the status recorded it exits 1 with 31
FAIL rows, and arms (1)-(9) stay GREEN throughout, which is the point: the strings were
never the witness.

run() and warm() now record the status, name the answer file in the report and return
it; the (10) loop sets its own accumulator and skips a comparison whose two sides are
no longer a cold answer and its replay. Arm (11), which already proves each reader can
see what it looks for, gains the same proof for both invokers in both directions — a
refused invocation IS reported, a succeeding one is NOT — so the guard is one that has
been observed red rather than one that has only ever been green (§2 rule 4).

… 94, absorb loop unioned, pins re-derived

#139 (Ruby arguments and rescue classes) landed on main at kParserVer 93 and kCacheVersion 21 while this
branch also spent 93. The parser version is one monotonic counter, so this branch takes 94. Seven conflicts,
none in the fix itself; src/ingest_parsepool.h and src/ingest_sidecap.h merged clean.

- src/ingest_cache.h, src/quality.h: kParserVer and kIngestParserVerMirror 94; kCacheVersion and
  kIngestCacheVersionMirror keep main's 21. This change filters which records are extracted and gives no
  record a field (dropPreprocDead reads the existing site bytes; Include is read through `byte`, never
  aggregate-built, so #139's new isValueUse field does not reach it). Both notes are kept, 94 above 93, and
  the 94 note now says a v93 blob is what it rejects and that the cache format stays #139's 21.
- test/qschemetrip.hash: re-derived on the merged tree (neither side hashed the 94/21 declaration lines),
  with a RE-PIN LOG entry in test/qschemetripcheck.sh.
- test/regression.sh: main's loop order kept, ppdeadrolescheck inserted where this branch had it (608).
- README.md, docs/EVALS.md, present/deck5_ripwire_build.js: gate count regenerated by
  docs/gatecount_build.py (608 at 8 sites).
- test/printf_parity.manifest and docs/COMMANDS.md regenerated from the merged build: no label moved and
  no byte changed.

…dule/name/arity resolution) — parser version 95

REHEARSAL ONLY — local branch pr81-rehearsal, never pushed. Resolves the 15 conflicted files of
merging main into @henry-hz's head 9046edc, assuming PR redhat-et#139 (kParserVer 93, kCacheVersion 21) and
PR redhat-et#172 (kParserVer 94) land first:

- src/ingest_cache.h, src/quality.h: kParserVer / kIngestParserVerMirror 95 (branch carried 87, main 92);
  kCacheVersion / kIngestCacheVersionMirror 21 (redhat-et#139's format; redhat-et#81 changes no record shape).
- src/ingest_elixir.h, src/ingest_sidecap.h: the branch's semantics kept (ElixirContext scopeOf/moduleOf,
  attribute refs, alias/atom/dot/__MODULE__ receivers, the refined @-attribute filter); converted to
  main's redhat-et#127 API (fieldChild/NodeField, kindIs) since the by-name nodeFieldText overload is gone on
  main. NodeField gains Operand (src/infra/fieldid.h). #include <charconv> added (review item 1).
- src/graph.h: PROVISIONAL accounting on the Elixir no-candidate drop — disposition Undefined/Unresolved
  instead of Unaccounted, so main's 6b8dc9d conservation alert stops firing on every Elixir corpus
  (it fired on test/elixirfix: 10 of 19 sites). No edge changes; review item 2's design choice stays open.
- test/regression.sh: gate-list union (606 + elixirsemanticcheck = 607); test/gateexitcheck.sh: both rows.
- test/qschemetrip.hash, test/printf_parity.manifest, gate-count sites, docs/COMMANDS.md: regenerated
  from the merged build. docs/captures/*: main's side (the 09-12 capture's graph.h seed now needs a
  ref-clean re-record: rankGraphTeleport moved 3357 -> 3371).
- CHANGELOG.md, README.md, docs/ARCHITECTURE.md: both sides, renumbered to 95/21/10.

Wanted gate set after this commit: gates=12 pass=11 fail=1 — the one failure is showcasecapturecheck
arm (H), the seed line, which only a re-recorded capture can fix.

…— kParserVer stays 95 over redhat-et#139's 93, absorb loop unioned, pins re-derived

Eight conflicts: version ladders, re-pin logs, the absorb loop and generated counts. No Elixir or Ruby
logic conflicted. redhat-et#172 (kParserVer 94) is merged next, so this commit's 95 already sits over both.

- src/ingest_cache.h, src/quality.h: kParserVer and kIngestParserVerMirror stay 95; both notes kept, 95
  above 93. kCacheVersion 21 keeps main's description of redhat-et#139's format change, plus the branch's note
  that redhat-et#81 appends RecvKind / LocalBindKind enumerators to the existing u8 and changes no record shape.
- test/qschemetripcheck.sh: both RE-PIN LOG entries, the Elixir pair above redhat-et#139's.
- test/qschemetrip.hash: re-derived on the merged tree (UPDATE_GOLDEN=1 starting from main's value). It
  equals the branch's pre-merge ce851b68: main changed no manifest function, and the branch already
  declared 95 over 21.
- test/regression.sh: main's loop order kept, elixirsemanticcheck and elixirnamearitycheck inserted where
  the branch had them (609).
- README.md, docs/EVALS.md, present/deck5_ripwire_build.js: gate count regenerated by
  docs/gatecount_build.py (609 at 8 sites).
- CHANGELOG.md merged clean: the Elixir entry (parser version 95) and redhat-et#139's Ruby entry both kept.

Binary-derived outputs (test/printf_parity.manifest, docs/COMMANDS.md, the showcase capture) are
re-derived after the redhat-et#172 merge, from one clean build of the combined tree.

…— kParserVer 95 over redhat-et#172's 94, captureTagsFacts takes both parameters, pins re-derived

REHEARSAL, local only: redhat-et#172 (the `#if 0` filter over every role and definition) is not merged yet. Its head
is based on main 558a2e0, which the previous commit already brought in, so once redhat-et#172 lands the final
`git merge origin/main` has nothing left to resolve here. Ten conflicts; two are code.

- src/ingest_sidecap.h, src/ingest_parsepool.h: captureTagsFacts keeps both new parameters — redhat-et#81's Elixir
  bind/include outputs and redhat-et#172's decided-dead ranges, walked once per file by the worker — as
  (..., defs, refs, binds, includes, ppDead), and both call sites pass both. The function-local ppDead
  recompute the branch still carried is gone. redhat-et#172's firstRefOfFile window is taken before
  ElixirContext::prepare, so it spans every ref the function appends. At the tail redhat-et#172's filter runs
  first ("before anything else reads either one"), then redhat-et#81's defimpl expansion, then foldFieldDefs.
  The order changes no output: preprocDeadRangesFor is empty for every non-C-family language, so the
  filter is a no-op on an Elixir file and the expansion never runs on a C-family one. One comment
  paragraph says why the bind/include windows the function now appends (Elixir only) are not filtered.
- src/ingest_cache.h, src/quality.h: kParserVer and kIngestParserVerMirror 95; notes kept 95 / 94 / 93.
  kCacheVersion 21: neither redhat-et#172 nor redhat-et#81 changes a record shape.
- test/qschemetripcheck.sh: redhat-et#172's RE-PIN LOG entry kept under the Elixir pair, which records the second
  re-derivation.
- test/qschemetrip.hash: re-derived (UPDATE_GOLDEN=1 starting from redhat-et#172's 045d24c5) = ce851b68, the
  branch's own value: neither redhat-et#139 nor redhat-et#172 touched a manifest function or kMergeDiffArgs, and the hashed
  declaration lines read 95 over 21.
- test/regression.sh: redhat-et#172's loop order kept, elixirsemanticcheck and elixirnamearitycheck where the branch
  had them (610).
- README.md, docs/EVALS.md, present/deck5_ripwire_build.js: gate count regenerated by
