primary sink-location attribution Introduce SinkSite (file_rel, line, col, snippet, cap) carrying the primary sink source-location through function summaries. Swap SsaFuncSummary.param_to_sink and FuncSummary.param_to_sink from a coarse Cap map to a deduped SmallVec<[SinkSite; 1]> per parameter, with a backward-compatible cap_sites() helper and serde defaults so pre-phase-1 on-disk rows continue to deserialise cleanly. Extraction: SinkSiteLocator bundles the tree/bytes/file_rel needed by extract_ssa_func_summary; ParsedFile::extract_ssa_artifacts wires the locator in for the persisted pass-1 path, while pass-2 intra-file transient summaries fall back to cap-only sites (behavior unchanged). Merge: GlobalSummaries::insert now unions sink sites with (file_rel, line, col, cap) dedup via shared union_param_sink_sites helper. Database: JSON-serialised summary columns carry the new shape automatically; no schema change needed. Phase 2 will consume SinkSite in build_taint_diag() to overwrite the caller-site Finding.line with the callee's sink line when resolved via summary. Phase 1 keeps behavior unchanged: scanning tests/benchmark/corpus/rust/cmdi/cmdi_indirect.rs still produces the same (wrong) line 10 finding. Adds round-trip tests covering SinkSite solo, SsaFuncSummary with sink sites, legacy-JSON default handling for both summary types, and merge dedup. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * feat(taint): phase 2/5 thread SinkSite into SsaTaintEvent and Finding Plumb Phase 1's SinkSite through the event pipeline into Findings, no output change yet. SsaTaintEvent gains `primary_sink_site: Option<SinkSite>`; when the main or callback sink-emission path has non-empty `param_to_sink_sites`, filter to sites whose `(line != 0) && (cap ∩ sink_caps != ∅)` and emit one event per distinct site — the multi-primary collapse keeps each downstream Finding single-primary. Resolution: ResolvedSummary and SinkInfo gain mirror `param_to_sink_sites` fields, populated from `SsaFuncSummary.param_to_sink` (SSA + callback paths) and `FuncSummary.param_to_sink` (global paths). Label, local-summary, and interop resolution paths leave the field empty — they only ever had cap-level info to begin with. Finding: new `primary_location: Option<SinkLocation>` with `file_rel/line/col`. `ssa_events_to_findings` maps `event.primary_sink_site` → `Finding.primary_location`, filtering cap-only sites (`line == 0`) to `None` so the (0,0) sentinel never leaks to formatters. Dedup key extended with the primary location so multi-site events aren't collapsed back together. Invariants (debug_assert!): * every SinkSite reaching emission has `line != 0 && cap ∩ sink_caps != ∅` — enforced by the pick_primary_sink_sites* filters; * every populated Finding.primary_location has `line != 0` AND non-empty `file_rel` — the cap-only → None translation upstream guarantees this. Deliberately independent of `uses_summary`: that flag tracks whether the *taint chain* used a summary, whereas primary attribution requires only that the *sink* itself was summary-resolved. A local source reaching a cross-file sink produces `uses_summary=false` alongside a populated primary_location — documented on Finding.primary_location, covered by `cross_file_sink_finding_carries_primary_location`. build_taint_diag, SARIF/JSON/explanation formatters, and the benchmark scorer remain untouched: finding.line still comes from `cfg_graph[finding.sink]`, so cmdi_indirect.rs still reports line 10 and the benchmark's rs-cmdi-003 row still shows FN in the LOC column. Tests: `cross_file_sink_finding_carries_primary_location` (proves plumbing via a synthetic FuncSummary carrying a SinkSite at 42:5) and `cross_file_sink_cap_only_site_leaves_primary_location_none` (regression guard against cap-only sites surfacing). All 1566 lib tests + integration tests pass. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(output): phase 3/5 consume primary sink location in diag + SARIF When a finding's primary_location (populated in phase 2 from a callee summary's SinkSite) names the dangerous instruction inside a callee body, attribute the diagnostic line to that location instead of the caller's call site. The call site is demoted to a Call step in flow_steps, and a synthetic Sink step at the primary location is appended so analysts still see the full trace. Changes: - Add scan_root parameter to build_taint_diag so file_rel can be resolved back to an absolute path via a shared resolve_file_rel helper. Empty file_rel (single-file scans where namespace == "") resolves to the file under analysis. - Extend SinkLocation with snippet, carried from the upstream SinkSite so the formatter needs no second file read. - Relax the ssa_events_to_findings debug_assert to allow empty file_rel, which is valid when scan root equals the file itself. - SARIF: emit data-flow as codeFlows[0].threadFlows[0].locations[]; locations[0] already reflects the primary sink position via the updated diag line/col. Acceptance: scan on tests/benchmark/corpus/rust/cmdi/cmdi_indirect.rs now reports line 5 (Command::new) as the primary sink, with the call site at line 10 visible in flow_steps. Two expect.json fixtures updated (must_match line_range widened): - javascript/taint/context_sensitive_call: 12-14 -> 7-14 (line 8 is the real sink inside run()). - rust/cfg/closure_async: 10-10 -> 10-11 (line 11 is Command::new inside the closure). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(bench): phase 4/5 validate primary sink attribution across corpus Extend the benchmark scorer and ground truth to lock in phase 3's primary-location behavior, and add fixtures that exercise the new capability end-to-end. Scorer (tests/benchmark_test.rs): - Add optional `expected_call_site_lines: Option<Vec<[usize; 2]>>` on Case. When present, score_location_level additionally requires at least one flow_step in the finding's evidence trace to fall within ±2 of the call-site range. When absent, the check is skipped — fully forward-compatible with existing fixtures. - Retain ±2 tolerance on expected_sink_lines (compared against the now-primary Diag.line post-phase-3). Ground truth edits: - rs-cmdi-cross-001: expected_sink_lines [8,8] -> [9,9]. Line 8 is the transform::wrap call site (a cross-file propagator, not a sink); line 9 is Command::new, the real sink. The ±2 tolerance happened to mask this stale attribution but it was semantically wrong — phase 4 is the right time to correct it. Also adds expected_call_site_lines [8,8] so the new field is exercised on an existing cross-file case. - rs-cmdi-003: adds expected_call_site_lines [10,10] (run_cmd call). This fixture's sink (Command::new inside run_cmd at line 5) was the motivating case for phases 1-3; adding the call-site assertion guards against regression to caller-line attribution. New fixtures: - rust/cmdi/cmdi_indirect_multisink.rs (rs-cmdi-009): helper run_both takes two tainted params and invokes two Command sinks on consecutive lines. Locks in that primary line lands inside the helper (lines 5-6), not at the caller (line 12). Notes document that SinkSite is currently one-per-callee so both findings today collapse onto the first sink; expected_sink_lines=[5,6] and expected_call_site_lines=[12,12] stay valid either way. - python/cmdi/cross_indirect_sink/{app.py,helper.py} (py-cmdi-cross- 004): sink os.system lives in helper.py (cross-file), caller in app.py reads env source and calls run_cmd. Verifies phase 3's cross-file primary attribution: Diag.path = helper.py, Diag.line = 5, with app.py:7 recorded in flow_steps as a Call step. Acceptance: - `cargo test --test benchmark_test -- --ignored --nocapture` passes. - rs-cmdi-003 is TP/TP/TP (the target flip FN->TP at LOC). All pre-existing TP/TP/TP fixtures remain TP/TP/TP; 2 new fixtures are TP/TP/TP. - Aggregate rule-level: TP=158 FP=10 FN=1 TN=97, P=0.940 R=0.994 F1=0.966 on the 266-case corpus (was TP=156 FP=10 FN=1 TN=97 on 264 pre-phase-4, delta is the +2 new cases both resolving TP). - Full `cargo test` green (1566 lib tests + all integration tests). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(taint): phase 5/5 lock Finding.primary_location contract via regression test Add a regression test in src/taint/ssa_transfer.rs that wires up a synthetic SsaFuncSummary with a SinkSite at other.rs:42:10 and drives the three emission stages (pick_primary_sink_sites → emit_ssa_taint_events → ssa_events_to_findings) against a minimal caller SSA body. Asserts the resulting Finding.primary_location is exactly that triple. The existing integration tests in src/taint/tests.rs cover the coarse FuncSummary path end-to-end through analyse_file. This test locks in the lower-level SSA-side plumbing so a future refactor that silently drops the site between pick → emit → findings fails here rather than only at the benchmark layer. Also refreshes tests/benchmark/results/latest.json (timestamp only; rs-cmdi-003 remains TP/TP/TP and the aggregate P/R/F1 are unchanged from phase 4). Closes the primary sink-location attribution feature (phases 1-5/5): * Phase 1 — SinkSite data model on summaries. * Phase 2 — SinkSite threaded into SsaTaintEvent and Finding. * Phase 3 — diag + SARIF consume primary_location. * Phase 4 — benchmark validates primary_call_site_lines across corpus. * Phase 5 — regression test locks the event→finding contract. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * refactor: clean up formatting and improve readability in multiple files * refactor: simplify type definition for deduplication key in findings * test(harness): add must_not_match expectation for FP regression guards Extends ExpectedFinding with must_not_match field that asserts a diagnostic must NOT fire — presence is a hard failure.
