📝 WalkthroughWalkthroughThe GraphQL shape audit now reports schema fields that decoder packages do not select. It adds package-wide aggregation, coverage and uncovered-operation reporting, sent-field declarations, JSON output, stale-declaration checks, mutation-error gating, tests, and documentation. ChangesGraphQL sent-field audit
Priority: ➖ Normal Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to This adds GraphQL response-shape reporting, but it can underreport fields for a second package decoding the same schema type, reducing the report’s reliability. The documented exclusion count is also inconsistent. Resolve these before merge. Sequence Diagram(s)sequenceDiagram

Change “six exclusions” to “five exclusions.” The text lists connection plumbing, the cursor object, meta fields, argument-required fields, and clientMutationId. The union rule is traversal behavior, not an additional exclusion.

R-PATH asks what GitLab sends that we fail to publish, and it can only ask it of REST: the oracle is GitLab's OpenAPI record, joined through a client-go struct. The eleven GraphQL-only domains pair with no such struct and appear in that record nowhere, so they contributed zero findings to every dimension of the 1:1 audit. Nothing had ever asked what our GraphQL surface fails to expose. cmd/audit_graphql_shapes already holds the three things the question needs, at the same position of one walk: the pinned schema, the document as GitLab receives it, and the struct the answer decodes into. So the third leg goes there rather than into a second command that would need its own copy of the document folding and decoder resolution. It reports 970 fields the schema offers at an object one of our decoders reads that no document of the decoding package selects, 236 undeclared after nine declarations. The list is not noise: a branch rule that never says who may push, a DAST location's hostname, param and requestMethod, a note's internal flag, a mutation payload's quickActionsStatus. Three things this design gets right that a naive walk does not. The claim is package-wide because a per-document claim is false of the package a reader acts on: branchrules expresses a licensing tier as a CE document that omits codeOwnerApprovalRequired and an EE document that selects it, and judging documents alone reported that deliberate omission as a gap. Evidence is what a document selected AND decoded, since a field asked for and dropped surfaces exactly as little as one never asked for. A finding is filed against the package whose struct decodes the object, not the one the call sits in: every epic note mutation goes through a shared wrapper, and filing it against the wrapper named a package that publishes nothing. The depth rule is our own decoders and the document, never the schema graph. The operation root alone would have contributed 17,497 findings, and it is not a response: its fields are other requests. What it does not cover is named in the report rather than left to be discovered: 38 GraphQL operations in 7 packages whose documents client-go builds, which R-PATH cannot see either. It reports and does not gate, having no tier oracle and no deprecation oracle, and both absences are stated on the report. The one sub-class that does gate is a mutation payload whose errors no field of the decoder reads, which turns a refusal into a success. The first defect it found is in this repository: vulnerabilities declares web_url and fills it nowhere, because no document selects webUrl.

…t arguments SonarCloud's S107 on this pull request: report and askSchema each declare eight parameters against a limit of seven. Both are the same shape. report takes everything one run produced, so it now takes an auditResult holding the provenance line, the pairings, the findings, the problems and the stale declarations, next to the sentRun the sent report already took. askSchema takes one position of the walk, so it now takes an objectPosition holding the schema type, the decoding struct's fields, the selection set, what was selected, what of that was decoded, whether a leaf is read, the path and the Go type. Spelled out, that second list is two maps of one type and a bare bool in a row of eight, which is exactly the call a reader cannot check by eye.

R-PATH asks what GitLab sends that we fail to publish, and it can only ask it of REST: the oracle is GitLab's OpenAPI record, reached through a client-go struct. The eleven GraphQL-only domains pair with no such struct and appear in that record nowhere, so they contributed zero findings to every dimension of the 1:1 audit. Nothing had ever asked what our GraphQL surface fails to expose.
This adds the third leg to
cmd/audit_graphql_shapes, which already holds the three things the question needs at the same position of one walk: the pinned schema, the document as GitLab receives it, and the struct the answer decodes into. A second command would have needed its own copy of the document folding and the decoder resolution, which is exactly the divergencecmd/internal/graphqlintrospectexists to prevent.It reports 970 fields the schema offers at an object one of our decoders reads that no document of the decoding package selects, 236 undeclared after nine declarations. The list is not noise: a branch rule that never says who may push, a DAST location's
hostname,paramandrequestMethod, a note'sinternalflag, a mutation payload'squickActionsStatus.Three decisions carry the design, and each was reached after a reviewer found the naive version wrong.
The claim is package-wide, because a per-document claim is false of the package a reader acts on.
branchrulesexpresses a licensing tier as a CE document that omitscodeOwnerApprovalRequiredand an EE document that selects it, and judging each document alone reported that deliberate omission as a missing field. Evidence is what a document selected and decoded: a field asked for and dropped surfaces exactly as little as one never asked for, so counting it would let a dead selection silence the package's real gap.A finding is filed against the package whose struct decodes the object, not the one the call sits in. Every epic note and discussion mutation goes through a shared wrapper in
toolutil, and filing findings against the wrapper named a package that publishes nothing and made all 29 of its same-name annotations wrong.The depth bound is our own decoders and the document, never the schema graph. The operation root alone would have contributed 17,497 findings, and it is not a response: its fields are other requests, which the action catalog already owns.
What it does not cover is named in the report rather than left to be discovered: 38 GraphQL operations in 7 packages whose documents client-go builds, which R-PATH cannot see either. By operation count that is more surface than the walk covers, and saying so is the point. Coverage is published as a breakdown rather than one number: 199 positions reached, 133 asked about, 52 traversed, 14 a repeated type, plus three silences counted at their sites.
It reports and does not gate. It has no tier oracle and no deprecation oracle — the schema declares no tier, since GitLab gates a GraphQL field at resolve time, and the pin carries no
@deprecatedbecause the introspection drops the directives on decode. Both absences are stated on the report rather than absorbed, and both are closed by one sidecar record from a fetch that already carries the data. The one sub-class that does gate, on every run, is a mutation payload whoseerrorsno field of the decoder reads, which turns a refusal into a reported success.The first defect it found is in this repository:
vulnerabilitiesdeclaresweb_urlon its item and assigns it nowhere, because no document selectswebUrl. The field has been empty for as long as it has existed, and the audit's own annotation was hiding it until the annotation was renamed to the lead it actually is.Three reviewers read the first version and all three returned needs-work; two more read the fix and both returned landable, with two medium defects that this branch also closes.
