v1.15.12

Engram v1.15.12 focuses on agent reliability: Pi setup is now first-class, MCP project selection is safer for long-lived hosts, cloud sync validates persistence before acking, and plugin memory flows survive compaction with clearer UI.

Highlights

• Pi setup is now one command: engram setup pi installs gentle-engram, installs pi-mcp-adapter, and writes Pi MCP config without overwriting an existing Engram server.
• MCP project overrides work for hosted agents: engram mcp --project <name> and ENGRAM_PROJECT are trusted process-level defaults for current-project, read, and write resolution while keeping explicit per-call validation strict.
• Autosync acks are safer: Engram now validates cloud accepted_seqs before acking local mutations, preventing local data from being marked synced when the server did not confirm the whole batch.
• Claude/OpenCode save nudges are restored: compatibility endpoints for latest observations and session lookup now match existing plugin hook behavior.
• Cloud relation mutations unblock sync: relation/upsert mutations are accepted, canonicalized, validated, and retained in cloud mutation chunks.

Contribution highlights

Thanks to the issue reports that shaped this release:

• @yvolchkov and @ardelperal helped tighten the setup path with engram setup pi and the OpenCode auto-start copy.
• @deliriumlabs flagged the broken save-nudge hook, which led to the restored observation/session compatibility endpoints.
• @AshrafAKRahman reported the mem_save content-loss bug, now fixed with stricter validation and backward-compatible payload handling.
• @alexandervazquez98 and @quirozino surfaced the autosync ack safety gap, now guarded by accepted-seq validation.
• @ricardoarz-dev, @aleka, and @samuelcooke-cpu drove the MCP project override work for long-lived agent hosts.
• @parraletz helped unblock cloud relation mutation sync, with @IrrealV and @forNerzul surfacing adjacent repair/local-sync follow-up areas.
• @gabrielizalo helped identify an external OpenCode TUI plugin failure mode and clarify the recovery path.

Pi companion updates

• Published gentle-engram@0.1.4.
• Added compact memory tool chrome for Pi memory calls.
• Added private-block redaction and compaction recovery helpers.
• Kept Engram-specific memory UI in gentle-engram, not in core Pi.

Fixes included

• mem_save now preserves observation content and accepts the backward-compatible observation alias while rejecting empty saves.
• Claude Code plugin context no longer includes bilingual trigger noise.
• OpenCode setup no longer tells users to manually run engram serve &; the plugin auto-starts the HTTP server when needed.
