Uses the bounded summary API from git-pkgs/sarif#10 to detect committed SARIF files through repository history. Records tools, effective levels, baselines, rules, suppressions, and CWE taxa with their names and categories.
Summary by CodeRabbit
New Features
Repository scans now detect stored SARIF reports and summarize tools, result levels, rules, baselines, suppressions, and CWE classifications.
Summaries include document totals and tool versions. Invalid SARIF files are reported as candidates, and processing limits are indicated when summaries are truncated. Test, example, and bundled or derived paths are excluded from SARIF scanning.
Documentation
Updated scanning guidance to describe SARIF summaries, processing limits, and path exclusions; clarify that test paths remain eligible for fuzzing; and include license files among those checked for binary classification.

Repository scans now inspect eligible SARIF files and emit bounded document, tool, result, rule, suppression, and CWE summary signals. SARIF signals participate in repository-file cleanup and replacement. Tests and README documentation cover the scanning behavior.
Changes: SARIF repository signals
Layer / File(s)
Summary
SARIF discovery and scan integration detector.go, go.mod, repository_files.go
The structured-file scan routes .sarif and .sarif.json files to SARIF inspection. It excludes paths classified as bundled or derived, tests, or examples. Inspection limits are 16 MiB, 5,000 unique values, and 100 tools. SARIF signals participate in repository-file cleanup and replacement.
SARIF summaries and validation repository_files.go, repository_files_test.go, README.md
SARIF summaries include document totals, tool versions, and sorted counts for levels, baselines, rules, taxa, and suppressions. Recognized CWE taxa produce weakness and category counts. Invalid input produces an invalid candidate. Limit errors or truncation add a truncated coverage signal. Tests cover summary signals, exclusions, truncation, and repository log output. The README describes the summaries, parsing limits, and path exclusions.

Merge Risk: Moderate · previous review de4f0
SARIF summaries can report CWE weaknesses that are not in the report, and can omit taxa the report does declare. This affects the accuracy of the new signals, not the stability of scanning. Fix the summary library and pin the corrected version, or accept the limitations, before merging.
Security architecture risk: Low · up to de4f0
The new processing is confined to repository analysis and produces descriptive metadata rather than granting permissions or executing report content. Per-file limits and explicit invalid or truncated results reduce exposure. Aggregate resource use across large repository histories remains an uncertainty.
Retained concerns
No architecture-level concerns identified.
Security review details
Security Blast Radius
inferred — A repository author can influence eligible SARIF inputs throughout the analyzed history and therefore affect metadata and resource consumption in that scan process. The inspected flow does not establish a tenant-wide, service-wide, or privileged execution outcome.
Security Findings and Attack Paths
observed — The inspected parser consumes an io.Reader using JSON decoding, with no filesystem, network, or subprocess API. The production Git-tree filesystem opens blob objects, validates tree-relative paths, and does not follow symlinks. SARIF content therefore does not acquire external-resource authority through this parsing path.
Trust Boundaries and Controls
observed — Malformed SARIF is converted into an invalid candidate without publishing partial document summaries. Byte-limit errors or collection truncation produce an explicit truncated coverage signal. Report-derived names and counts remain descriptive input, not authenticated evidence about repository security.
Resilience and Maintainability Implications
observed — On an underlying read or close failure, repository scanning retains cloned parent signals and records a detector error; a subsequent commit forces a full retry. This failure-state model predates the PR. Ordinary SARIF syntax errors are handled as replacement candidates instead, so they do not create the stale-parent-state condition suggested by the initial uncertainty.
Hardening Proposals
proposed — For deployments that analyze untrusted repositories, consider scan-wide memory and output budgets plus cancellation-aware parsing, complementing the existing per-file limits. This is a containment proposal, not a verified resource-exhaustion finding.

Full details: Title check
Explanation
The title "Detect committed SARIF history" matches the main change. The PR adds SARIF detection in repository history: repository_files.go routes structured-file inspection through repositoryStructuredSignals, which scans eligible SARIF files and emits document, tool, level, baseline, rule, taxa, and suppression signals. The title is short, specific, and free of file lists or vague terms, so a teammate scanning history can identify the primary change.

164-164: Trivial · Maintainability & Code Quality · Low value
Document that SARIF detection skips test and example paths.
sarifFilePath returns false for paths that roles.Match labels as bundled, derived, test, or example. The test at repository_files_test.go line 177 confirms that testdata/results.sarif produces no signals.
This line says "Test paths remain eligible because fuzz targets commonly use them". A reader can apply that sentence to SARIF files and expect signals from test paths.
Add one sentence that states the SARIF exclusion.

classified by roles.Match as bundled, derived, test, or example, so the existing
statement about test paths remaining eligible for fuzz targets is not mistaken
as applying to SARIF files.
