v1.10 Hardening

Release v1.10

Security Hardening: path traversal prevention, YAML safe deserialization, JSONL integrity with checksums, learning safety with drift tracking, and access control with audit logging. Five capabilities closing every known security vulnerability — the Foundation and Hardening eras complete with a clean security posture.

Capabilities Introduced

Architectural Decisions

Path traversal prevention at all file operation boundaries — skill names sanitized before use in filesystem paths; no user-controlled string reaches a file path without sanitization
SHA-256 checksums on JSONL entries — append-only integrity with anomaly detection and compaction; data poisoning attacks detectable through checksum validation
60% cumulative drift threshold for learning safety — prevents gradual skill corruption from adversarial corrections; drift tracked per-correction and cumulatively
Hook error boundaries — orchestrator hook failures isolated from main pipeline execution; one bad hook cannot crash the entire skill loading process

Breaking Changes

None.
