v1.16.2

Highlights

• Adds observation lifecycle state derived from review_after.
• Adds mem_review for listing memories that need review and marking one reviewed.
• Adds Pi-native review support through the Engram HTTP server for gentle-engram.
• Pins critical observations in context so important memory is harder to bury.

Changes

Memory lifecycle

• Surface computed observation state as active or needs_review.
• Add store-level review queries and local-only review reset behavior.
• Expose lifecycle metadata through MCP save/search responses.

MCP, HTTP, and Pi

• Add MCP mem_review for direct agent integrations.
• Add HTTP review routes used by gentle-engram Pi-native tools.
• Add compact Pi chrome for review list and mark-reviewed flows.

TUI and docs

• Show lifecycle state in the TUI list/detail views.
• Document mem_review, lifecycle metadata, HTTP routes, and Pi setup behavior.

Install

brew upgrade engram

Compatibility notes

• mark_reviewed resets the local review cycle only; lifecycle review timestamps are not synced yet.
• Pi users should pair this with gentle-engram@0.1.8 for native mem_review support.
