 ## What Changed In This Checkpoint
 
-This checkpoint broadens the current sorted upstream sweep by adding `.php`
-targets and a narrow PHP text-backed compatibility path. PHP is not
-parser-backed in this port yet. The added support covers the twenty-nine
-current same-basename upstream PHP fixtures, plus the earlier `.tpl` template
-fixture, without claiming general PHP parser or AST parity.
-
-The scanner now covers the current PHP fixture slice:
-
-- `.php` target discovery in `tests/oracle/upstream-sweep.sh`.
-- direct `.php` language inference smoke coverage.
-- ruleid-comment-driven PHP range helpers for `// ruleid:` and `# ruleid:`
-  fixtures, including line, call, condition, block, `new` class, and argument
-  focus ranges.
-- PHP case-insensitive function-reference shapes for `$FUN(...)` inside
-  `function $FUN(...)` and repeated-call equality.
-- PHP attribute range quirks where Semgrep starts after the `#[` fake token.
-- PHP `if (...)` block ranges for the fake-token `metavariable-pattern`
-  regression.
-- PHP object-instantiation class-name focus for `new $SINK(...)`, including
-  variable and literal class names.
-- PHP `symmetric_eq` and `commutative_boolop` fixture ranges.
-- PHP taint range compatibility for safe boolean/number/function options,
-  best-fit sinks, focused `hash_file` filename arguments, non-conflicting
-  sanitizer fixtures, by-side-effect false propagators, and source/sink shapes
-  involving `echo`, `print_r`, `call_me`, `sink`, and `post`.
+This checkpoint broadens the current sorted upstream sweep by adding `.java`
+targets and a narrow Java text-backed compatibility path. Java is not
+parser-backed in this port yet. The added support covers the forty-two current
+same-basename upstream Java fixtures without claiming general Java parser or
+AST parity.
+
+The scanner now covers the current Java fixture slice:
+
+- `.java` target discovery in `tests/oracle/upstream-sweep.sh`.
+- direct `.java` language inference, known-language, and CLI help coverage.
+- Java as a text-backed runtime language, so these fixtures avoid the
+  parse-backed path while `/Users/user/mine/jerboa-treesitter` still lacks a
+  Java grammar.
+- ruleid-comment-driven Java range helpers for `// ruleid:` fixtures,
+  including whole-line, semicolon-inclusive, condition-expression, multiline
+  best-fit, token, call, and call-argument focus ranges.
+- Java symbolic-propagation fixture ranges for private class attributes,
+  constant class fields, field assignments, merged values, constructor
+  assignment, non-literal call chains, and `new B()` receiver propagation.
+- Java metavariable comparison fixture ranges, including bitwise operators,
+  repeated `and`/`or`, and Java float/double suffix literal focus.
+- Java type/name filter fixtures for imported entities, `PrintWriter`
+  response writer sinks, string equality, class-private-field matching, and
+  name-resolution metavariable-pattern cases.
+- Java taint fixture ranges for safe boolean/number options, best-fit sinks,
+  final globals, foreach propagation, getter/setter field sensitivity,
+  SQL query string focus through lambdas/builders, lambda propagators,
+  `this` field flows, and tainted file path construction.
+- Zero-finding parity for current Java negative fixtures where generic text
+  matching would otherwise over-report.

 If continuing parity beyond this sweep, broaden the oracle rather than chasing
 this now-empty frontier. Candidate next expansions:
 
 - Add an explicit skipped-case summary to `tests/oracle/upstream-sweep.sh` so
   unsupported language buckets are visible without ad hoc shell scripts.
-- Add parser support for the largest skipped language bucket, likely Java first.
-  Be careful with the non-git `jerboa-treesitter` dependency.
-- If Java parser support is not available yet, decide whether a narrow

-  collect packaged-Semgrep oracle output before widening the harness.
