feat(checker): flag scalar comparisons on any()/all() results - #476
Conversation
RY107 any-all-scalar-comparison (warning): a comparison with a direct base-resolving any()/all() call on one side and a numeric literal on the other, when the comparison does not preserve the call's scalar logical. any()/all() return a length-1 logical that numeric comparison coerces to 0/1, so the outcome is exactly one of three families: preserving (== 1, != 0, > 0, >= 1) computes what the bare call computes and stays silent -- that is diffobj's !all(diff(x)) == 1L idiom, pinned must-stay-silent in testdata/ry095_ry096_real_shapes.R; negating (== 0, != 1, <= 0, < 1) computes !any(x); constant (> 1, >= 2, < 0, == 2, ...) is a dead guard. The negating and constant outcomes are reported with the element-level rewrite, closing the glue R/utils.R:32 false negative the Posit audit recorded (any(lengths) == 0 where any(lengths == 0) was meant, issue #356): FALSE == 0 is TRUE, so the written guard runs on the wrong condition. The original constant-condition sketch was rejected because it could not separate the glue bug from diffobj's legitimate comparison; classifying by outcome instead of shape separates them exactly. Positioning against the neighbors: RY093/RY100 own comparisons nested inside length()/nchar()/math calls (RY107 yields when either already reported the same span), RY105 owns the length(any(...)) wrapper shape, and any(x == 0) -- the comparison inside the call -- fires nothing. NA input propagates to NA in every family, which changes neither classification. Multi-argument calls (na.rm) and non-literal operands are out of scope; no dataflow.
Hermetic reruns of both manifests against the new checker add exactly one RY107 identity, the flagship true positive from issue #356: - tidyverse (33 packages): glue R/utils.R:32:7 in both the R/-only and package-root reports; ledger gains it as true_positive/upstream-glue (11 TP now), source_sha256 recomputed over the regenerated non-posit root-report set. - posit fast tier (35 packages): the same glue identity in posit.glue reports; posit.glue.txt goes from empty to the one finding; ledger gains it as true_positive/upstream-package and the message ledger records its message. Seven reviewed false-positive RY010 identities also disappear from the posit fast tier because their carrier files are syntax-error fixtures (lintr RConfigInvalid/lintr_test_config.R:3:1 and six testthat entries in test-parallel/syntax-error/tests/testthat/test-error-1.R) whose semantic diagnostics the recovered-tree suppression merged in #467 now withholds by design; that change landed after the previous posit reconciliation, so the ledger was carrying them stale. The RY000 identities at the same sites remain. posit-messages prunes the same seven. clean_checkout.rs now relativizes report identities against the vendored package root the way run.sh's writer does (R/utils.R), instead of flattening to a file name; the two formats could not both agree with a non-empty committed report, which the empty baseline had masked.

PR #473 independently removed the same seven stale lintr/testthat RY010 identities my branch had removed (both trace to #467's recovered-tree suppression), refreshed the posit README row, and recomputed the posit source_sha256 over the pruned report set. Take main's reconciliation as the base everywhere and re-apply only this branch's own net posit delta: the single glue R/utils.R:32:7 RY107 true_positive identity (ledger finding, message entry, posit.glue reports, SUMMARY rows, glue package count 1->2, true_positive 37->38, upstream-package 27->28). The posit source_sha256 is recomputed over main's 62-report set plus the one new glue line; ry_commit points at the RY107 checker commit. The README posit row gains the same +1 (392 / 38 / 354 / 0), and the stale tidyverse row is refreshed alongside it (75 / 11 / 41 / 0, +23 unowned) since this branch's tidyverse ledger change moves those counts; #473 had aligned only the posit row.

One provenance fix before merge: the posit ledger's source_sha256 no longer matches the committed posit root reports — it was recomputed for the tidyverse ledger but not the posit one.

- Merged the #473 posit baseline and re-resolved the reconciliation on top (
19165ab): the seven recovered-tree RY010 removals are now attributed to #473's commits rather than duplicated here, both ledger notes survive the merge resolution without duplication, and no code came in via the merge — the net tree delta against the previously reviewed head is two corpus files. - Recomputed the posit ledger provenance:

Note: the posit, ecosystem, and test CI lanes were still in flight at review time; the ledger digest and the hermetic reconciliation both verify locally, so nothing here depends on their outcome.

Every fired/silent decision matches the R-derived family; no misclassification found (no preserving form fires; no negating or constant form is silent, apart from the negative-literal P3). Two review-prompt expectations corrected against real R: <= 1 is not value-preserving (FALSE <= 1 and TRUE <= 1 are both TRUE — constant TRUE) and the rule correctly fires on it; != 2 is constant TRUE and fires. Runtime divergence re-verified: with lens <- c(0L, 3L), any(lens) == 0 is FALSE while any(lens == 0) is TRUE.

Regeneration adjudication
Ruling: nothing to remediate in this PR — the tidyverse catch-up regeneration is not here. Git archaeology:
- This branch forked from main at
5031e86(fix(checker): suppress semantic diagnostics for files parsed from recovered trees #467). At that commit and at the PR base07e67b1(ecosystem: reconcile posit ledger with recovered-tree suppression #473),tidyverse-0.7.1.jsonalready contained 74 findings (10 TP / 41 FP / 23 unowned). - The 103-to-74 drop (29 unowned ggplot2 RY010 identities) landed on main in
1784245("ecosystem: reconcile reports and ledgers with the 0.5.1 vendor"), part of merged release PR chore(release): prepare 0.10.0 #460, before this branch existed. The 0.10.0 CHANGELOG entry states it outright: "Resolving the scales inventory clears the ggplot2 RY010 false-positive batch from both committed ecosystem ledgers." - This PR's net ledger delta vs main is exactly one identity per ledger: glue
R/utils.R:32:7RY107 true_positive (tidyverse 74-to-75, TP 10-to-11; posit 391-to-392, TP 37-to-38), plus the README summary rows catching up to the chore(release): prepare 0.10.0 #460-era ledger values (the rows had been stale on main: 103 / +52 vs actual 74 / +23). - All 29 dropped identities spot-checked at the pin: I ran the built branch binary (identical to main for these shapes — no RY107 fires on ggplot2; the clean_checkout change is test-only) on the cached ggplot2 checkout at the exact manifest pin
6870419aa6e1...: zero of the 29 locations fire. The dropped lines reference scales-package names (rescale,squish,censor,rescale_max,fullseq,ContinuousRange) that the r-typeshed 0.5.1 scales inventory now resolves — consistent with chore(release): prepare 0.10.0 #460's attribution.
On the fold-in question as posed: folding a full ledger regeneration into a feature PR would have deserved pushback (#473 precedent stands), but this PR contains no such regeneration — only the single-identity delta its own reconciliation produced, and a two-line README row alignment that the repo convention already owes any ledger-touching PR. Appropriate as merged; no split-out needed. If the review record believed a tidyverse catch-up was folded in here, correct the record, not the PR.
clean_checkout.rs scope ruling
Keep — appropriate fold-in, and a forced one. The old test flattened diagnostic paths to file_name() while run.sh's write_report relativizes against the package dir (verified: ecosystem/run.sh strips package_dir/, producing R/utils.R:32:7), so the two formats could never agree on a non-empty report. The committed glue.txt has been empty, making the comparison vacuously green; RY107 makes it non-empty for the first time, so without this fix the baseline test fails on this very PR. A standalone fix on main would be untestable there (empty vs empty passes either way, demonstrable only via the falsification test). The fix mirrors run.sh's relativization with a file_name() fallback — separately motivated but causally coupled; carrying it here was the right call.

The preserving list names three of the four quiet forms — >= 1 is the fourth (TRUE >= 1 is TRUE, FALSE >= 1 is FALSE), and the implementation's outcome test silently keeps it (pinned by all(x) >= 1 in both the diagnostics and recall-rule tests; infer/recall.rs:367 documents all four). As written, a reader would expect all(x) >= 1 to warn when it stays silent. Adding >= 1 (or an e.g.) closes the gap.

Model NA in RY107 outcomes. check_any_all_scalar_comparison evaluates only FALSE (0.0) and TRUE (1.0). Base any() and all() can also return NA, and comparisons propagate that NA. Therefore, any(x) > 1 is never TRUE but is not always FALSE; similarly, the current “always TRUE” wording is incorrect for the opposite constant family, and negating comparisons also produce NA when the call does.
Use wording such as “never TRUE” or “never FALSE” instead of claiming a constant result. Update the RY107 summary, changelog, and regression cases.

Separate current RY107 evidence from the archived snapshot.
The archived ledger at 941981428b76c43a078179b3b1619209b9802f17 records ec702b587f2ab5a78f64182654d2b1865b44adb0 and contains no RY107 finding. The current RY107 row comes from the later checker commit 9c1e3c17e4fb67f9a4c8d7a87d526dac8cec0164. The document provides no addendum or current-generation label for this row or its completeness totals.
Update the snapshot provenance and totals, or move RY107 and the current completeness counts into a separately labeled addendum.

PR #476 (RY107, any-all-scalar-comparison) landed on main while this branch was in review. Re-merge main and regenerate both corpora with the combined ruleset: the only identity movement is additive -- this branch's five RY106 true positives (hms, blob, gt x3) on top of #476's glue RY107 finding, with no interaction between the two rules. Both source_sha256 digests are recomputed over the merged root reports and ry_commit points at the merge; both run.sh --check gates and check-ledger.py pass.

Closes #356.
Approach
RY107
any-all-scalar-comparison(warning): a comparison operator with a direct base-resolvingany(...)/all(...)call (exactly one positional argument) on one side and a numeric literal on the other, when the comparison does not preserve the call's scalar logical value.any()/all()return a length-1 logical that numeric comparison coerces to 0/1, so the outcome is exactly one of three families, decided by evaluating the operator at FALSE=0 and TRUE=1:== 0,!= 1,<= 0,< 1): computes!any(x)— reported asTRUE exactly when the call is FALSE.> 1,>= 2,< 0,== 2,>= 0, ...): dead guard — reported asalways FALSE/always TRUE.== 1,!= 0,> 0,>= 1): computes exactly what the bare call computes — silent.The preserving carve-out is the crux. The original
constant-conditionsketch was rejected (see the former recall.rs module doc) because "is always FALSE" was wrong (FALSE == 0is TRUE) and because the shape seemed indistinguishable from diffobj's legitimate!all(diff(x)) == 1L, pinned must-stay-silent intestdata/ry095_ry096_real_shapes.R. Classifying by outcome rather than shape separates them exactly: diffobj's comparison preserves the value, glue's negates it. NA input propagates to NA in every family, changing neither classification. The message suggests the element-level rewrite with mirrored operands (0 == any(x)suggestsany(x == 0)).Neighboring-rule positioning map
length(x == y),nchar(x == y)— comparison INSIDE a counting callabs(x > y)— comparison inside a numeric math calllength(any(1L)) > 0—length()of a scalar reduction vs 0any(x == 0)— comparison inside any()/all()any(x) == 0/all(x) > 1— comparison OUTSIDE with any()/all() as direct operandNo span is double-reported: RY093/RY100 are emitted at the enclosing call before its arguments are inferred, so RY107 (running at the comparison's BinOp site) scans for a same-span RY093/RY100 and yields — the same suppression pattern
emit_condition_diagnosticsalready uses for RY100 vs RY001/RY003. RY105 requires alength()call as an operand, a different shape from the bare any/all call, so the two cannot meet on one comparison. Shadowed callees (any <- function(...)), foreign-qualified ones (otherpkg::any), multi-argument calls (na.rm), and non-literal operands stay silent;base::anykeeps the premise.R-verified evidence (Rscript, R 4.6.1)
length(any(c(1,2)))is 1,typeoflogical;any(c(NA,FALSE))is NA andNA == 0is NA.FALSE == 0is TRUE /TRUE == 0is FALSE (negating);TRUE > 1andFALSE > 1both FALSE (constant);TRUE == 1LTRUE /FALSE == 1LFALSE (preserving, the diffobj family).lengths <- c(0L, 3L),any(lengths) == 0is FALSE whileany(lengths == 0)is TRUE — the written guard skips the zero-length branch (the issue'srecycle_columnserror).Fixtures and tests

Hermetic reruns of both manifests: RY107 adds exactly one identity everywhere — glue
R/utils.R:32:7, the audited defect itself — recorded as true_positive in both ledgers (upstream-glue/upstream-package); summaries and the posit message ledger updated; tidyversesource_sha256recomputed over the fully regenerated set. The posit fast tier also surfaced pre-existing drift from #467 (merged after the last posit reconciliation): seven stale false-positive RY010 identities in syntax-error fixtures (lintr, testthat) whose semantic diagnostics the recovered-tree suppression now withholds by design; their RY000s remain. Removed with explanation in the ledger note.clean_checkout.rswas fixed to relativize identities against the package root likerun.sh's writer (R/utils.Rinstead of a bare file name) — the empty baseline had masked that the two formats disagree.Gates
