/**
|
|
* PreToolUse(Read) wrapper — path-deny for Read tool.
|
|
* Router-gate v4 emergency fix (Smoke 5 2026-05-30).
|
|
*
|
|
* Spec §3.1 declared transcript JSONL hard-deny but Read tool had NO
|
|
* path-protection — controller could Read ~/.claude/projects/*.jsonl
|
|
* (parent context exfil from other sessions). Same for runtime artifacts,
|
|
* .env, normative files.
|
|
*
|
|
* Reuses DEFAULT_PROTECTED_PATTERNS from shell-content-rules.mjs.
|
|
* Fail-CLOSE on internal error (security default).
