## [Unreleased]
+## [0.6.1] - 2026-05-03
+
+A precision pass on auth and resource analysis plus three fresh CVE corpus pairs, plus a UTF-8 slice panic in the path abstract domain. Closes ~1900 Go auth FPs on gitea-shaped helpers, the mastodon/diaspora private-callback Ruby controller pattern, and a phantom-taint outbreak from JS/TS / Java lambda shorthand in jest-style nested test callbacks.
+
+### Added
+
+- Java JDBC raw-SQL sinks. `Statement.execute`, `Statement.executeBatch`, and `Statement.executeLargeUpdate` modeled as `SQL_QUERY` sinks, classified via type-qualified resolution (`DatabaseConnection.execute`) so bare `execute` (Runnable, Executor, HttpClient) does not over-fire. `conn.createStatement()` and `conn.prepareCall()` now infer return type `DatabaseConnection`, so the JDBC chain `Statement s = conn.createStatement(); s.execute(q)` types `s` correctly. Closes GHSA-h8cj-hpmg-636v (Appsmith FilterDataServiceCE.dropTable). Vulnerable + patched Java fixtures added.
+- Java/Kotlin `Pattern.matcher(value).matches()` chain recognised as a `ValidationCall` allowlist. Receiver of `.matcher(` must contain `regex` or `pattern`. Validation target is the `.matcher()` argument, not the bare `.matches()` receiver. Branch narrowing applies the `validated_must` to the input variable on the surviving branch. Same GHSA as above (`FILTER_TEMP_TABLE_NAME_PATTERN.matcher(tableName).matches()`).
+- Per-parameter SSA summary probe now receives `BodyMeta.param_types`, so `extract_ssa_func_summary` runs a local `analyze_types_with_param_types` pass before extraction. Helper bodies whose sinks resolve only via type-qualified callees (e.g. `DatabaseConnection.execute` for JDBC `Statement.execute`) no longer drop the sink during cross-function summary extraction. Fixes the Appsmith helper `executeDbQuery(query)` that routed SQL through `statement.execute(query)`.
+- Short-circuit branch condition CFG nodes now mirror `condition_vars` into `taint.uses`, so `apply_branch_predicates` interns the variable for short-circuit-decomposed validators (`if (x == null || !regex.matcher(x).matches()) throw`). Without this, the per-disjunct cond nodes built via `build_condition_chain` silently no-opped and `x` never reached `validated_must` on the surviving branch.
+- Go `goqu.L(s)` and `goqu.Lit(s)` raw-SQL literal builders modeled as `SQL_QUERY` sinks. Safe siblings (`goqu.I` identifier, `goqu.C` column, `goqu.T` table, `goqu.V` parameterised value, `goqu.SUM`, `goqu.COUNT`, …) stay unlabeled. Gin source list extended with the array-returning siblings of the existing scalar helpers: `c.QueryArray`, `c.GetQueryArray`, `c.PostFormArray`, `c.GetPostFormArray`. Closes CVE-2026-41422 (daptin: `c.QueryArray("column")` → `goqu.L(project)` with the loop variable lifted through `for _, project := range columns`). Vulnerable + patched Go corpus pair under `tests/benchmark/cve_corpus/go/CVE-2026-41422/`.
+- Go `for ident := range iter` def-use lifting. The `range_clause` child of `for_statement` is now consulted when `left`/`right` aren't direct fields of the `for` node, so taint from the iterable reaches the loop binding. Required for the daptin CVE shape above.
+- Rust format-string named-argument lifting (`format!("...{x}...")`, stable since 1.58). Identifiers captured by `{name}` / `{name:fmt-spec}` are pulled into the call's `uses` for known format-style macros: `format`, `print`/`println`, `eprint`/`eprintln`, `write`/`writeln`, `panic`, `format_args`, `assert`/`debug_assert`, `todo`, `unimplemented`, `unreachable`, plus log-crate severity macros (`info`, `warn`, `error`, `debug`, `trace`). Recursive descent through one or two layers of expression wrapping (`format!("{x}").to_owned()`, RHS chained method calls). Without this, taint stopped at the macro boundary. `let q = format!("...{x}...")` carried no `x` because the identifier lives in format-string bytes rather than as a separate AST argument node. Mirrors the Python f-string lifter.
+- Rust CVE corpus extended. CVE-2023-42456, CVE-2024-32884, CVE-2025-53549 vulnerable + patched fixtures under `tests/benchmark/cve_corpus/rust/`.
+- Java lambda shorthand recognised by `extract_param_meta`. `lambda_expression`'s `parameters` field as a bare `identifier` (`cmd -> …`) or as an `inferred_parameters` wrapper around identifiers (`(a, b) -> …`) was not matching the formal_parameter / spread_parameter kinds in `PARAM_CONFIG`, so the lambda appeared parameterless and the SSA pipeline treated its formals as closure captures. Mirrors the JS/TS arrow shorthand path.
+
+### Fixed
+
+- Panic on non-ASCII input to `has_first_char_absolute_check` in the path abstract domain. The 32-byte search window around `[0]` was sliced as `&clause[lo..hi]` (str), which panicked when `hi` landed inside a multi-byte UTF-8 char (e.g. the em dash `—`, bytes 34..37). Switched to `&bytes[lo..hi]` with `windows()` byte-pattern checks; all needles are ASCII so the searches are equivalent. Surfaced by `cargo fuzz` (`scan_bytes` target, `.c` extension path, embedded `—` in a comment near `s[0] == '/'`). Regression test added.
+
+### Fixed (false positives)
+
+- Go `unit_has_user_input_evidence` framework-request-name allow-list narrowed for Go. `ctx`, `context`, `info`, `body`, `path`, `payload`, `dto`, `form`, `query` are no longer treated as user-input indicators on Go: in Go these are `context.Context` (cancellation/value-bag from the stdlib) or struct-pointer payload params (`info *PackageInfo`, `opts *FooOptions`), not request bindings. Go HTTP frameworks bind the request to per-framework typed params (`r *http.Request`, `c *gin.Context`, `c echo.Context`, `c *fiber.Ctx`); these arrive at the gate via `RouteHandler` kind or the type-aware param filter below. Stdlib `req` / `request` (the `*http.Request` convention) preserved. Other languages keep the broader allow-list.
+- Go param collection drops `ctx context.Context` and `ctx context.CancelFunc` parameters entirely rather than seeding their names into `unit.params`. Tree-sitter-go's `parameter_declaration` exposes `name` and `type` as named fields; descend only into `name` so type-segment identifiers don't pollute the param-name set (`info *PackageInfo` no longer contributes `PackageInfo`). Together with the allow-list narrowing above, closes ~1900 `go.auth.missing_ownership_check` findings on gitea backend helpers whose only "user-input evidence" was the ubiquitous `ctx context.Context` first param.
+- Ruby controller method visibility + filter-callback gate. Methods marked `private` (bare `private` directive, targeted `private :foo, :bar`, or `protected`) and Rails filter callback targets (`before_action`, `after_action`, `around_action`, their `prepend_*` / `append_*` / `skip_*` siblings, and the legacy `*_filter` aliases) are no longer emitted as `Function` units. Visibility tracking is class-body source-order with two directive forms (bare toggles default visibility, targeted explicitly marks named methods). Block-form filters (`before_action do … end`) carry no symbol arg and are correctly ignored. Closes mastodon / diaspora `rb.auth.missing_ownership_check` flood on `set_X` row-fetch helpers used as `before_action` callbacks.
+- Field-LHS resource acquires no longer counted as local resource leaks at the `apply_assignment` site. `e->name = (char *)e + sizeof(*e)` (sub-buffer alias inside a returned struct) and `mem->buf = ptr` (local-into-field ownership transfer) now mark the RHS local `MOVED` and stop tracking the field as a separately OPEN resource. The parent struct owns the field's lifecycle. Cross-language (distinct from the Go-only `apply_call` field-LHS gate, which is restricted because JS/TS class-field acquires `this.fd = fs.openSync(...)` are the documented expected leak pattern in that path). Closes curl `entry_new` and equivalent C/C++ shapes in openssl / postgres.
+- Empty-formals SSA lowering signal. `lower_to_ssa_with_params` now sets `with_params=true` even when `formal_params` is empty, so an arrow `() => {…}` is treated as "explicitly zero formals" rather than "no formals info". External vars in a zero-formal arrow are now correctly tagged as synthetic closure captures, so the JS/TS / Java auto-seed pass cannot mistake a bubbled-up free var (e.g. `userId` lifted from a nested jest test callback) for a real handler formal. Closes 934 phantom taint findings on the outline test suite (`describe("…", () => { test("…", () => { server.post(…) }) })`-shaped fixtures).
+- Rust integer-typed values now suppress `Cap::FILE_IO` at the abstract-domain leaf gate (previously HTML_ESCAPE only). An integer's decimal representation is digits with optional leading `-`, never path metacharacters (`/`, `\`, `.`); magnitude is irrelevant. Closes the sudo-rs RUSTSEC-2023-0069 patched FP `let uid: u32 = user.parse()?; path.push(uid.to_string())`.
+
## [0.6.0] - 2026-05-02
A focused release that splits data-exfiltration off from SSRF and ships sinks for outbound HTTP request bodies across all 10 languages, with calibration tuned so plain user input echoed back upstream does not fire.

Engine fix: `lower_to_ssa_with_params` now signals `with_params=true` to `lower_to_ssa_inner`, which makes the synthetic-externals classifier always exclude formals (even when the formal list is empty, e.g. arrow `() => {…}`) — bubbled-up free vars become synthetic and the auto-seed pass skips them.
