 - GateGuard keys checked files by canonical path, resolving relative targets against the tool `cwd`, so `a.py`, `./a.py`, and the absolute path (or differently cased and separated Windows spellings) share one first touch. Keys from earlier state files are still honoured.
 - GateGuard gates a MultiEdit call as its `tool_input.file_path` when its entries do not name their own path, which is the tool's own shape; such calls were never gated before, including on sensitive files.
 - GateGuard gates NotebookEdit as a first-touch edit of its `notebook_path`; notebooks were never gated before.
+- GateGuard prior-search credit no longer counts a search that never saw the target. File-type filters (`rg -t`/`-T`/`--type`/`--type-not`, `fd -e`/`--extension`, the Grep tool's `type`), the Glob tool's pattern, shell glob operands, and git pathspecs now filter like include globs, so `rg -t py tokenizer src` or `Glob **/tokenizer.py` no longer credits `tokenizer.js`. A search confined to the target's own file name (`Glob **/tokenizer.js`, `find -name tokenizer.js`, Grep `glob: 'tokenizer.js'`) is a lookup and never credits it. PowerShell searches keep backslashes as path separators.
+- GateGuard no longer passes an edit as comment-only when its text contains U+2028, U+2029, or U+0085, which end a JavaScript or C# line comment.

+## Type filters
+
+A file-type filter is an include or exclusion in another spelling, so it
+filters the same way. `rg -t`/`--type` adds the type's globs as includes and
+`rg -T`/`--type-not` adds them as exclusions, using ripgrep 14.1's built-in
+globs for common languages. A type name outside that table, `--type-add` and
+`--type-clear` redefine what a type means, so they make the search an
+unreadable filter that never credits. `fd -e`/`--extension` is an include of
+`*.<ext>`. The `Grep` tool's `type` parameter is read like `rg -t`.
+
+## Path patterns
+
+A glob in a path argument limits the files a search sees just as an include
+does, so it must match the target for the stem to count. The `Glob` tool's
+pattern is matched against the target's path below its root, with `*` inside
+one directory and `**` across directories. A shell path operand with glob
+characters (`rg x src/*.py`) is expanded by the shell before the search runs;
+it admits the target when it matches the target or a directory above it,
+since a matched directory is searched recursively. A git pathspec
+(`git grep x -- '*.py'`) matches the same way, except that its `*` also
+matches `/`. Literal operands keep their scope rule, and one operand that
+admits the target is enough. PowerShell escapes with a backtick, so a
+PowerShell search is tokenized with its backslashes kept as path separators.
