Smoke 5 (user-run 2026-05-30) found 5 of 6 self-exfil vectors OPEN — parent context transcripts (~/.claude/projects/*/<session>.jsonl) readable via: - Bash: ls ~/.claude/projects/, cat ~/.claude/projects/.../jsonl, head/tail - PowerShell: Get-Content / gc / Select-String - Read tool: direct file_path Spec §3.1 declared this protection but Stream B/C/G never wired path-deny. DEFAULT_PROTECTED_PATTERNS in shell-content-rules.mjs lacked ~/.claude/projects/. Read tool had no path-deny hook at all. Closure: - shell-content-rules.mjs: +1 regex /(^|\/)\.claude\/projects(\/|$)/i in DEFAULT_PROTECTED_PATTERNS. Bash hook + PowerShell hook already use this shared list via pathDenyOverlay → both close automatically. - enforce-read-path-deny.mjs (NEW): PreToolUse(Read) wrapper rejects any Read on isProtectedPath() match. Uses same shared DEFAULT_PROTECTED_PATTERNS for consistency (covers transcript / runtime / .env / normative / dep-checksums). - .claude/settings.json: register enforce-read-path-deny.mjs PreToolUse Read. Tests: shell-content-rules.test.mjs +3 path cases in protects %s + 1 dedicated it() block. enforce-read-path-deny.test.mjs +6 cases covering Read tool block. 1714/1714 vitest tools GREEN (was 1707, +7 net). Critical: re-run Smoke 5 in clean session before continuing other smokes. Expected post-fix: all 6 vectors blocked (Bash/PowerShell via path-deny, Read via enforce-read-path-deny, Write via existing normative-content-rules). Side observation from Smoke 5 session: controller self-fabrication of intermediate results (4 occurrences across Smokes 1-5) confirms one of the 7 fundamental limits — gate paradox + behavioral residual irreducible. No hook catches in-response narrative fabrication (not through tool-gate). This is a Stream H + recovery-procedures.md documentation item, not a hook fix.
