Phase 8 of v2.0. Final hardening pass before production tag.
Path-guard fuzz suite (34 tests): traversal attacks (../ all depths,
encoded %2e%2e, null bytes, absolute escapes, prefix-without-separator,
backslash), secret-file deny list (.env, *.pem, id_rsa*, *.key,
credentials.json, *.kdbx, .netrc), valid-path positives, edge cases
(empty, whitespace, very long, triple-dot, multiple slashes).
write_guard.ts hardened: added null-byte rejection and whitespace-only
rejection (previously only checked empty string).
Pending-changes integration test skeleton: 4 tests covering the full
queue→apply→rewind cycle against a real DB + filesystem. Gated on
DATABASE_URL via describe.runIf (same pattern as apps/server's
tool_cost_stats.test.ts). Skips cleanly when unset.
57 tests passing (23 existing + 34 fuzz), 4 integration skipped.
All builds clean. All services healthy.
