Native Harness Memory Bridge Signet's V1 release introduces the Native Harness Memory Bridge, a portable memory interface that indexes existing memory artifacts from harnesses such as Codex and Claude Code without re-extracting or claiming ownership. The bridge surfaces native memory files as external provenance-bearing artifacts, marks them deleted when files disappear, and filters Signet memory tools by default in Codex's MCP registration to avoid competing memory user experiences. Native Harness Memory Bridge Signet provides one portable memory interface across harnesses. When a harness already has its own memory system, Signet indexes that harness’s native memory artifacts as external provenance-bearing artifacts rather than re-extracting, rewriting, or claiming ownership of those memories. V1 implements the generic source abstraction for harness-owned memory artifacts. Codex memory files under ~/.codex/memories/ and automation-local memory files under ~/.codex/automations/ /memory.md are indexed into Signet’s artifact search layer and surfaced through recall as native memory results. Claude Code’s native memdir files under ~/.claude/projects/ /memory/ , ~/.claude/session-memory/ , and ~/.claude/agent-memory/ use the same bridge path instead of the previous Claude-only watcher that rechunked MEMORY.md into Signet-authored rows. When native memory files disappear, Signet marks their artifact rows deleted and excludes them from active recall rather than hard-deleting provenance. Normal Signet hooks remain the write path for Signet memories created from Hermes, OpenClaw, OpenCode, Claude Code, and Codex sessions. Codex’s MCP registration keeps hooks and non-duplicative Signet capabilities, but filters Signet memory tools by default so native memory plus hook-driven recall do not create two competing memory UXs.
