Memory that follows you: Palinode v0.13.0 goes cross-harness

[Paul-Kyle]

An agent can remember perfectly and still feel forgetful if the memory only appears when you stop and ask for it. Palinode v0.13.0 closes that gap: memory now follows the working turn across more harnesses.

The release adds two native recall paths:

• Claude Code gets a fail-silent UserPromptSubmit hook, installed by palinode init, that checks prospective triggers and runs a strict-threshold search before each prompt.
• Pi gets a native extension with session-start priming, per-turn recall, and shutdown capture.

Both use the same environment knobs. Both inject memory into the conversation rather than rewriting the system prompt, so the provider's prompt-cache prefix remains stable. A new cross-harness guide maps native hooks, native plugins, and MCP integrations in one place.

The default implicit-recall threshold also moves from 0.75 to 0.5, based on the measured BGE-M3 calibration already carried by Palinode. Injected hits now show the raw cosine score—the same scale the threshold actually controls—so tuning matches what you see.

There is a second story in this release that matters just as much: nine inbound PRs from five external contributors shipped in the three days since v0.12.0. Thank you to floze-the-genius, WilliamK112, SkxOverKill, ColumbusLabs, and Tethys0. The contribution pipeline—claim, review, merge, preserve authorship, and carry the work into a release—is working in public, not just described in a contributing guide.

Also shipped: MCP result-size audit fields, a bounded MCP search limit, deterministic bullet-list migration, relative-date lint findings, safer injection scanning, and a fix for oversized API searches crossing sqlite-vec's KNN ceiling.
