 - 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.
 - Claude Code home installs (`ecc install --target claude` and `install.sh`) now install under `CLAUDE_CONFIG_DIR` when it is set, matching the directory Claude Code reads its user-level config from. Previously ECC wrote to `~/.claude` regardless, so when `CLAUDE_CONFIG_DIR` redirected the config root the install never loaded ("installs, but nothing loads"); the settings.json, plugin.json, hook commands, bundle and install state were all stranded in `~/.claude` while Claude Code read an empty `CLAUDE_CONFIG_DIR`. The claude-home adapter now resolves its root the same way the runtime does (`CLAUDE_CONFIG_DIR || ~/.claude`), consistent with the opencode adapter and `resolveClaudePaths`.
+- `GATEGUARD_EXEMPT_GLOBS` judges the target's real location as well as the path as written, so a symlink inside an exempt tree no longer exempts the first touch of a file it points to outside the globs (#3655).

+An exemption requires both the path as written and its symlink-resolved
+location (for a new file, the real path of its nearest existing ancestor) to
+match an exempt glob. The resolved location is judged
+against the project root's real path for relative globs and, for absolute
+globs, against the glob with its literal leading directories resolved (`/tmp`
+is `/private/tmp` on macOS). Otherwise a link in an exempt scratch directory
+would exempt any project file it names. A real location that cannot be
+resolved grants no exemption; Windows-style paths on a POSIX host keep the
+lexical match, as for the other real-path checks. Hard links are not path
+aliases and are still covered by the precedence above.
