What it is

Local-first shared memory layer for AI coding agents across MCP clients, Git history, reasoning context, and project sessions.
— the description by AVIDS2

Summary from the brain’s metadata

Local-first shared memory layer for AI coding agents across MCP clients, Git history, reasoning context, and project sessions. One project memory system for Claude Code, Codex, CodeBuddy Code, Cursor, Windsurf, Copilot, Gemini CLI, OpenCode, Grok Build, OpenClaw, Hermes Agent, Oh-my-Pi, Pi, Kiro, Antigravity, Trae, DeepSeek Harness, WorkBuddy, and any MCP-capable agent.

How it works

Memory model: Hybrid

AutoGineer overview, from the brain’s own files

Memory model: Hybrid. Folders: .github (agent config, 3 files); .windsurf (agent config, 2 files); assets (attachments, 32 files); docs (docs, 65 files); examples (examples, 4 files); packages (source code, 836 files); scripts (scripts, 18 files); src (source code, 382 files). The agent writes CLAUDE.md.

Memorix gives the AI coding agents you already use a shared, searchable project memory that survives new chats, IDE switches, terminal sessions, and handoffs. The memory lives under the Git project, not inside one chat window or one tool.

Use Claude Code today, Codex tomorrow, and Cursor in the afternoon. The agent can change; the project memory stays the same.

Use Memorix when you keep re-explaining the same project to a new agent session: the last session already figured something out, another IDE cannot see it, or a design decision is buried in a chat you cannot find anymore.

ProblemWhat Memorix adds
The next session forgets what the last session learnedProject-scoped memory, session summaries, timelines, and detail retrieval
Different agents know different thingsOne local memory pool available through MCP, hooks, CLI, SDK, and the bundled terminal agent
Git records what changed, but agents cannot recall it wellGit Memory turns commits into searchable engineering facts
Architecture decisions disappear into old chatsReasoning Memory stores why choices were made, with alternatives and trade-offs
Static rule files driftGotchas, fixes, and project skills evolve from real work
Parallel agent work gets messymemorix orchestrate coordinates task context, handoffs, locks, verification, and review loops

Memorix is local-first. SQLite is the canonical store. Small projects use the in-process Orama path; larger projects use a persistent SQLite FTS5 candidate index and, when available, an optional local LanceDB semantic shadow index. Both indexes are rebuildable and are never a limit on how many durable memories you can keep. LLM-backed formation and embedding remain optional.

Capabilities

Memorix is more than a memory store. It also installs agent integrations, keeps useful work events, turns commits into project facts, exposes a local control plane, and can coordinate multi-agent work when a task needs it.

Memorix connects through the interfaces each agent already supports: plugin packages, MCP, project rules, hooks, skills, or the bundled terminal agent. memorix setup chooses the right setup for each agent and keeps stdio MCP as the default transport.

See Integration Surfaces for the current support matrix and what each generated file means.

Use the same setup command without --global only when you intentionally want repo-local guidance, rules, or hooks in the current Git project.

CLI, MCP, and HTTP are different entry points:

  • memorix CLI is the direct command surface for setup, memory search/store, Git Memory, import/export, dashboard, orchestration, diagnostics, and automation.

  • memorix serve is the stdio MCP bridge used by IDEs and coding agents. Its default tool profile is micro, so agents see only the compact core tool set.

  • memorix background start / memorix serve-http run the HTTP service for a shared endpoint, dashboard, VPS Docker deployment, or multiple clients.

Multi-device store sync is opt-in and separate from HTTP sharing. It never uploads the live SQLite database or WAL files. By default it only relays qualified project-visible observations for the current Git project; personal, agent-targeted, candidate, and ephemeral records stay local. Pass --scope user to include every local project. Set MEMORIX_SYNC_PROVIDER and inspect memorix sync store status --json before the first push.

<h2 id="install"><picture><source media="(prefers-color-scheme: dark)" srcset="assets/tags/light/section-install.svg"><img src="assets/tags/section-install.svg" alt="Install" height="32" /></picture></h2>

Requirements:

  • Node.js >=22.18.0

  • Git, because project identity is derived from the real Git root

Install and initialize:

npm install -g memorix
memorix init --global                   # optional defaults
memorix setup --agent claude --global   # or codex, copilot, cursor, pi, gemini-cli, opencode,
                                       # codebuddy, windsurf, kiro, antigravity, trae, openclaw, hermes, omp

memorix init is optional. It creates or updates TOML configuration:

  • ~/.memorix/config.toml for global defaults

  • <git-root>/memorix.toml for optional project overrides

Legacy memorix.yml, .env, and ~/.memorix/config.json are still read for compatibility, but new setup flows use TOML.

If you want repo-local guidance or hooks for a specific repository, run the same setup command from inside that repo without --global. Codex is the exception: its supported path is the user-level plugin install, so Memorix leaves project .codex configuration alone.

<h2 id="quick-start"><picture><source media="(prefers-color-scheme: dark)" srcset="assets/tags/light/section-quick-start.svg"><img src="assets/tags/section-quick-start.svg" alt="Quick Start" height="32" /></picture></h2>

Connect an existing agent

Use the setup command first. The global form is the normal one-time install:

memorix setup --agent claude --global
memorix setup --agent codex --global
memorix setup --agent copilot --global
memorix setup --agent cursor --global
memorix setup --agent pi --global
memorix setup --agent gemini-cli --global
memorix setup --agent opencode --global
memorix setup --agent windsurf --global
memorix setup --agent kiro --global
memorix setup --agent antigravity --global
memorix setup --agent trae --global
memorix setup --agent openclaw --global
memorix setup --agent hermes --global
memorix setup --agent codebuddy --global
memorix setup --agent omp --global
memorix setup --agent dsh --global
memorix setup --agent workbuddy --global
memorix setup --agent grok --global

What it installs depends on the target agent, but the goal is the same: make Memorix available wherever you open that agent without asking you to wire every repo by hand.

  • Claude Code: installs the Memorix plugin package, adds CLAUDE.md guidance, and enables hook capture when you do not pass --noHooks.

  • Codex: installs one user-level Memorix plugin with bundled stdio MCP, skills, and lifecycle hooks. It does not write project-local .codex config or change your model, approval, or sandbox settings. When Codex asks, review the plugin hook definition once with /hooks; --noHooks skips automatic capture.

  • GitHub Copilot CLI: installs the Copilot plugin package and official Memorix skills.

  • Pi: installs the Pi extension/skills package and native MCP config (Pi 1.0+): ~/.pi/agent/mcp.json with --global, or .pi/mcp.json for project setup.

  • Cursor: writes Cursor MCP/rules/config entries in the chosen scope.

  • Gemini CLI: installs the extension package, GEMINI.md context, hooks, and skills. Antigravity CLI has an official Gemini CLI migration path, but Gemini CLI remains an active standalone target.

  • OpenCode: installs the local plugin file, opencode.json, skills, and AGENTS.md guidance.

  • Windsurf, Kiro, Trae: write the MCP/rules/hooks files the target supports.

  • Antigravity: installs the official plugin package with plugin.json, mcp_config.json, hooks.json, rules, and skills under ~/.gemini/config/plugins/memorix or .agents/plugins/memorix.

  • OpenClaw: installs an OpenClaw-compatible bundle with .mcp.json, official skills, and an OpenClaw HOOK.md/handler.ts hook pack.

  • Hermes Agent: installs into Hermes home (%LOCALAPPDATA%\hermes on native Windows, ~/.hermes elsewhere, or HERMES_HOME), enables the plugin in config.yaml, registers plugin hooks, slash/CLI commands, skills, and writes MCP config.

  • CodeBuddy Code: installs a user-scope local marketplace plugin under ~/.codebuddy/memorix-local with MCP, skills, and hooks. It does not change existing CodeBuddy model, permission, or settings files; CodeBuddy keeps third-party hook approval in its own /hooks flow.

  • Oh-my-Pi: installs an omp.extensions package with extension hook events, a memorix command, official skills, and writes MCP config.

  • DeepSeek Harness: writes a Memorix @deepseek-ai/dsh-mcp-client row into $DSH_HOME/cordis.patch.yml (default ~/.dsh/cordis.patch.yml), appends guidance to the harness AGENTS.md, and installs official skills under $DSH_HOME/skills. The row follows DSH's own shipped Memorix reference, so tools appear as mcp__memorix__*.

  • WorkBuddy: writes a Memorix MCP server row into ~/.workbuddy/mcp.json (or <project>/.workbuddy/mcp.json for project installs) and appends guidance to AGENTS.md. Tools appear as mcp__memorix__*; there is no hooks surface.

  • Grok Build: installs native lifecycle hooks under ~/.grok/hooks/memorix.json and guidance in ~/.grok/AGENTS.md. MCP stays host-owned by default; pass --mcp http to write [mcp_servers.memorix] with url = "http://localhost:3211/mcp". Project-local hooks require Grok /hooks-trust, while global hooks are trusted. Set GROK_HOME to use a custom Grok home.

Need a quieter install? Add --noHooks for targets where setup can control hook capture separately from the host's official package entry. It keeps MCP and guidance, but skips Memorix hook capture.

If you intentionally want repo-local guidance or hooks, run the same command inside that repository without --global.

If your agent only needs a manual MCP entry, use stdio:

{
  "mcpServers": {
    "memorix": {
      "command": "memorix",
      "args": ["serve"]
    }
  }
}

For an npm-based MCP client or registry tester, use the complete command npx -y memorix serve. The serve argument matters: memorix without arguments opens the bundled memcode terminal agent when run by a human, while MCP clients should start the stdio server explicitly.

For a manually managed Claude Code entry, add "alwaysLoad": true inside the memorix server object. This lets Claude Code expose Memorix tools during print-mode startup; memorix doctor agents --agent claude can detect and repair a missing setting.

HTTP is not required for normal setup. Use it only when you intentionally want a shared background service, dashboard, VPS Docker deployment, or multiple clients using the same endpoint. Local development uses the Node service directly and does not require Docker:

memorix background start

Then point the client at:

http://localhost:3211/mcp

In HTTP mode, agents should bind the active repo explicitly with memorix_session_start(projectRoot=...) when the client can provide the workspace path. Git remains the final source of truth for project identity.

Uninstall

Preview what will be removed:

memorix uninstall --dry-run

Stop the background service and remove hooks:

memorix uninstall --background --hooks

Full cleanup:

memorix uninstall --yes --background --hooks --purge-data
npm uninstall -g memorix

memorix uninstall reports MCP config entries for manual cleanup instead of silently editing every MCP file it finds.

The CLI is direct and does not depend on an MCP session. It binds to the current Git project, or to the project supplied with --cwd. Without an active identity it reads, writes, and exports project-visible memory only. Use memorix identity join or memorix identity use --agent-id <id> only when you intentionally need personal/team memory or coordinated task actions; memorix identity clear returns the terminal to project scope. --as <active-agent-id> is the one-command alternative for scripts. Both camelCase and kebab-case flags are accepted.

Manage controlled media

Media is opt-in. An explicit local import is copied into Memorix's local data directory, hashed, and kept outside the Git worktree. It becomes normal memory only when you attach it. Memorix never captures every screenshot or tool output. An asset may be up to the configured media limit (100 MiB by default). Automatic vision analysis is deliberately capped at 20 MiB; a larger image is still kept and can be attached, but Memorix records a clear text fallback instead of sending an oversized payload to a model provider.

memorix media import --path ./architecture.png --json
memorix media attach --asset <asset-id> --title "Architecture diagram" --json
memorix media list --kind image --json
memorix media show --asset <asset-id> --json
memorix media remove --asset <asset-id> --force --json

# Controlled derivations: explicit, bounded, and attachable to memory.
memorix media derive-pdf --asset <asset-id> --attach --json
memorix media derive-audio --asset <asset-id> --attach --json

# Legacy image analysis now uses the same controlled asset lifecycle.
memorix ingest image --path ./architecture.png --json

MiniMax image generation is a deliberate CLI operation. Video generation returns a durable job immediately; inspect or cancel that job rather than waiting in an agent request.

# Configure MINIMAX_API_KEY in your user environment or .env, never in Git.
memorix media generate image --prompt "A clean system architecture diagram" --json
# Image-to-image with a reference image (MiniMax image-01 / image-01-live):
memorix media generate image --prompt "Keep the subject, change the background" --image ./reference.png --json
memorix media generate video --prompt "A short product walkthrough" --json
memorix media status --job <media-job-id> --json
memorix media cancel --job <media-job-id> --json

memorix_media is the compact MCP companion in every profile, including micro. It supports import, attach, list, show, PDF/audio derivations, generation, and job status. MCP image and video generation are disabled by default because they may incur provider costs. Set MEMORIX_MCP_MEDIA_GENERATION=1 only after you deliberately want an agent to request billed MiniMax output. The normal OpenRouter text embedding lane is still text-only; media vectors are created only by a provider that explicitly declares support for that modality. Text descriptions and attachments remain a useful ordinary retrieval fallback.

Compact Continuityrecent host-native compact summaries or lifecycle markers"What survived the last context compaction?"

Search is project-scoped by default. scope="global" searches across projects. The search boosts Git Memory for "what changed" questions and reasoning records for "why" questions.

Long-term memory is deliberately not an automatic dump of every note. A source observation, Claim, workflow, session, and code snapshot keep their existing roles. An agent may ask memorix_store to create an additional long-term record; an explicit request auto-qualifies and enters task briefs as a durable anchor, while hook-captured or Git-derived candidates stay pending until qualified. Approval stays an explicit operator review. Use memorix memory long-term approve|archive|supersede to record the evidence-backed lifecycle. Only a manually created or user-confirmed user + portable item may be considered in another local project; project code, Git facts, tests, workflows, sessions, and observations cannot be promoted into portable user memory.

memorix context "..." is the default Memory Autopilot entry. It builds a compact task-lensed brief for agents: bugfix tasks lean toward tests and repros, release tasks lean toward package/changelog/build checks, onboarding tasks lean toward docs and entry points, and stale or unrelated memories stay in warning lanes instead of flooding the prompt. Use --fallback --brief-json when MCP is unavailable and a CLI fallback needs the same bounded brief plus a receipt of what was selected or omitted; --json remains the detailed diagnostic form. A normal new task does not receive an old-session dump. For an explicit continuation, memorix resume "..." adds only the latest useful session summary, up to three readable durable anchors, and at most one recent source-labelled host compact checkpoint. A durable anchor carries a durable:<id> reference, so an agent can expand the full reviewed record through memorix_detail only when needed. Keyword matches stay primary; when no reviewed durable item matches and an embedding provider is configured, Memorix makes one 1.8-second, no-retry semantic fallback for paraphrases or cross-language tasks. A slow or unavailable provider simply leaves the normal keyword-only Workset intact. A checkpoint is lifecycle evidence, not durable memory or a transcript backup. Agents should read the suggested files before trusting stored memory.

memorix serve defaults to --mode micro (9 tools) to keep MCP tool schemas small for agents. memorix setup writes --mode lite (21 tools) into the installed MCP config so the normal memory, continuity, and session surface is reachable. Use --mode team (29 tools) for coordination tools, or --mode full (48 tools) for advanced and compatibility tools such as checkpoint inspection.

Shortcuts and aliases: memorix search / remember / recent are direct query shortcuts, bg/bs start the background service, hook runs the hook launcher, and memorix config get|path|migrate inspects or migrates config files.

memorix orchestrate uses the current checkout for single-worker runs. When running multiple workers, it creates task worktrees under .worktrees/ and merges successful task branches back. Use --isolated to force worktree isolation for one worker, --no-worktree to disable it, --allow-dirty to run with uncommitted changes, and --no-auto-merge to preserve task worktrees for manual review.

Minimal ~/.memorix/config.toml:

[agent]
provider = "openai"
model = "gpt-4o"
api_key = "..."

[memory.llm]
provider = "openai"
model = "gpt-4o-mini"
api_key = "..."

[embedding]
provider = "auto"

[memory]
inject = "minimal"
formation = "active"

Use [memory.llm] and [embedding] for Memorix memory quality and retrieval. Use [agent] for the model memcode talks to while coding. Keep credentials in global config or environment variables, and do not commit secrets.

For the optional Atlas Cloud memory preset, run memorix init and choose Atlas Cloud, or set provider = "atlascloud" in [memory.llm]. It uses the OpenAI-compatible https://api.atlascloud.ai/v1 endpoint and reads ATLASCLOUD_API_KEY or the explicit MEMORIX_LLM_API_KEY.

For OpenRouter embeddings, use provider = "api", base_url = "https://openrouter.ai/api/v1", and model = "qwen/qwen3-embedding-8b". Memorix accepts OPENROUTER_API_KEY for that embedding endpoint; MEMORIX_EMBEDDING_API_KEY remains the explicit override.

For Requesty, choose Requesty in memorix init or set provider = "requesty" in [memory.llm] (endpoint https://router.requesty.ai/v1, key from REQUESTY_API_KEY or MEMORIX_LLM_API_KEY). Requesty embeddings use provider = "api", base_url = "https://router.requesty.ai/v1", and model = "openai/text-embedding-3-small" with REQUESTY_API_KEY.

For API Route, choose API Route in memorix init or set provider = "apiroute" in [memory.llm]. The preset uses https://global.api-route.com/v1 and deepseek-v4.1-flash, with your own API_ROUTE_API_KEY or MEMORIX_LLM_API_KEY. It is opt-in memory LLM processing; embeddings and memcode's model registry are configured separately. See configuration.

For Cheaper Inference, choose Cheaper Inference in memorix init or set provider = "cheaperinference" in [memory.llm]. The preset uses https://api.cheaperinference.com/v1 and gpt-5.4-mini, with your own CHEAPER_INFERENCE_API_KEY or MEMORIX_LLM_API_KEY. It is opt-in memory LLM processing; embeddings and memcode's model registry are configured separately. See configuration.

For Runcrate, choose Runcrate in memorix init or set provider = "runcrate" in [memory.llm]. The preset uses https://api.runcrate.ai/v1 and the open-weight deepseek-ai/DeepSeek-V4.1-Flash, with your own RUNCRATE_API_KEY or MEMORIX_LLM_API_KEY. It is opt-in memory LLM processing; embeddings and memcode's model registry are configured separately. See configuration.

For controlled MiniMax media generation, set MINIMAX_API_KEY (global) or MINIMAX_CN_API_KEY (China region) in your environment or .env. The media library never stores that key, a signed output URL, or base64 payloads. CLI generation is explicit; MCP generation additionally requires MEMORIX_MCP_MEDIA_GENERATION=1.

docs/MULTI-DEVICE-SYNC-RESEARCH.md

Multi-Device Store Sync — Plan and Acceptance Contract

Status: released in 1.9.0. Background sync, broader table replication, and encrypted snapshots remain future work. Scope: keep the existing local-first SQLite runtime; add an optional, provider-agnostic replication path so one user can keep the same memory across several machines.

Contribution credit: the design, initial implementation, and the object-store/Postgres follow-up came from Ravi Tharuma's PR #277. The local hardening branch keeps those commits in its merge history and adapts them to the current v3 contract. Prior art in this repo: docs/CLOUD_SYNC_AND_MULTI_AGENT_RESEARCH.md already sketched a "local SQLite + background cloud sync" hybrid but did not specify or build it. This document turns that sketch into a concrete, reviewable contract.

Decision Summary

The sync layer must replicate auditable memory events, never a live SQLite file. GitHub can be a low-cost relay for immutable JSONL batches, but GitHub LFS is not a database merge engine and is not the production default. The runtime keeps SQLite local and treats each remote as an interchangeable event transport.

The first supported contract is deliberately narrow:

  • Scope: the current Git project by default. A remote namespace includes the canonical project ID; one project cannot pull another project's events by accident.

  • Eligibility: project-visible, non-ephemeral, qualified/legacy durable observations only. Personal, agent-targeted, candidate, and ephemeral records are excluded unless a future explicit export policy opts them in.

  • Identity: every sync key includes the project ID. Unkeyed rows also carry origin device and origin ID, so global store IDs can never cross projects.

  • Transport: immutable per-device event batches, local cursors, checksums, bounded pulls, and idempotent replay. Remote cursors are not authoritative.

  • Conflict: logical version order decides the current visible row, while a losing concurrent version remains available as conflict/audit evidence rather than disappearing silently.

  • Device safety: a copied data directory is detected as a clone and must rotate its device identity before it can publish new events.

  • User experience: manual status, push, pull, and repair first; background sync is a later opt-in once retention and recovery gates pass.

GitHub Relay Contract

The GitHub adapter uses a private repository as a versioned transport, not as the canonical database:

events/<project-hash>/<device-id>/<sequence>.jsonl
snapshots/<project-hash>/<snapshot-id>.json.zst

Event files are immutable and device-owned. A device never edits another device's file and never commits memorix.db, memorix.db-wal, or memorix.db-shm. Each event contains a schema version, project namespace, device ID, sequence, entity key, operation, logical version, visibility decision, content hash, and payload. At-rest encryption is a future transport option; this first slice does not pretend to provide it. Credentials never enter project files or event bodies.

Snapshots are normalized, replayable memory state, not a copy of an open SQLite file. SQLite's Online Backup API may be used for a local backup, but a backup is not a merge input.

Acceptance Checklist

  • [x] memorix sync store status --json reports scope, eligible/skipped counts, remote namespace, cursor, pending batches, and conflicts without sending data.

  • [x] push and pull are idempotent and resumable after interruption.

  • [x] Two stores with independent local integer IDs converge to the same visible records while retaining local IDs locally.

  • [x] A stale upsert cannot revive a newer delete.

  • [x] A concurrent same-key edit keeps both the winner and a reviewable losing version/audit record.

  • [x] Personal, agent-targeted, candidate, ephemeral, and other-project rows are excluded by default.

  • [x] --scope user is an explicit opt-in that relays every local project's eligible rows through a separate user-global namespace. Privacy filters still drop personal, agent-targeted, candidate, and ephemeral rows. The live SQLite file is still never copied.

  • [x] Copying a data directory produces a clear device-clone error and a documented device rotate recovery path.

  • [x] GitHub relay protocol smoke proves only JSONL/snapshot artifacts are uploaded; no SQLite database or WAL file is present.

  • [x] Pulls are bounded and keyset-paged; remote logs have an explicit acknowledged retention/compaction path.

  • [x] Malformed, foreign-project, unsupported-version, and hash-mismatch input fails closed without mutating local memory.

  • [x] Local-only users see no behavior or dependency change when sync is unset.


1. Problem

A single user commonly runs Memorix on more than one machine — for example a workstation, a home machine, and a portable laptop. Today each machine keeps its own independent store at ~/.memorix/data (MEMORIX_DATA_DIR). There is no supported way to keep those stores current with each other, so the memory a user sees depends on which machine they happen to open.

Two deployment shapes are sometimes proposed to solve this. Both have real costs:

  1. Run one central Memorix service and point every machine at it over HTTP. serve-http already supports this (see docs/DOCKER.md). It gives a single shared store, but it trades away the properties that make Memorix useful on a workstation:

    • Project-scoped features degrade. Git-root detection, project binding, project memorix.toml/.env, and Git Memory require the service to see the repository at the path the client reports. A central host usually cannot see a laptop's working copy, so project-scoped semantics break while only global/shared memory keeps working. docs/DOCKER.md documents this as a real runtime limitation.

    • Latency on the hot path. Every context call, session start, and hook becomes a network round trip instead of a local SQLite read.

    • Offline stops working. A portable machine with no connectivity has no memory at all.

    • Single-writer contention. One SQLite file serving several machines serializes writes and invites SQLITE_BUSY.

  2. Replace SQLite with a central client/server database (e.g. Postgres). This contradicts the stated local-first product boundary in docs/KNOWN_ISSUES_AND_ROADMAP.md, and would require rewriting the synchronous better-sqlite3 store layer (src/store/*.ts) onto an async client with a different SQL dialect and a different vector story. It removes offline use and adds an always-on infrastructure dependency for what is meant to be a local tool.

Neither shape preserves local-first. The gap is a third shape: keep the store local on every machine, and add an optional replication layer that keeps those local stores consistent through an interchangeable remote.


2. Goals and non-goals

Goals
  • Preserve local-first: reads and writes stay on the local SQLite store; sync is asynchronous and off the hot path.

  • Keep working offline; reconcile on the next successful sync.

  • Be provider-agnostic: the remote is an interface, not a specific vendor. A local filesystem/rsync target, an object store (S3-compatible), or a small edge datastore must all be valid backends behind the same contract.

  • Be opt-in and safe: sync is disabled by default; enabling it never changes local behavior for users who do not use it.

  • Deterministic, explainable merge: a user can inspect what would change before it is applied, consistent with the preview-first maintenance model.

Non-goals
  • No real-time multi-writer coordination or distributed locking. That is the team/orchestration surface, not this.

  • No requirement to run a central Memorix service.

  • No replacement of the SQLite runtime or the retrieval/embedding model.

  • No claim of conflict-free collaboration between different users; this targets one user's several machines. Multi-user sharing is a separate concern.


3. Why the current schema already supports this

The canonical store carries most of what a convergent last-writer-wins (LWW) merge needs, and the small remainder lives in additive side tables so the observations schema never changes:

  • Stable cross-device identity. The integer observations.id is a replica-local counter (meta.next_id) — two machines can mint the same id for unrelated rows — so it cannot be the merge key. Sync instead derives a stable syncKey: t:<projectId>:<topicKey> for topic-keyed observations (naturally shared across devices) and u:<originDevice>:<originId> for unkeyed ones, minted once and recorded in sync_row_state. Each replica maps a syncKey to its own local id on import, so id collisions are impossible.

  • Convergent versioning. Merge uses a per-row logical clock (revision, writer) — a Lamport counter advanced from the last observed revision, tiebroken by the originating device id — persisted verbatim in sync_row_state. This is a strict total order, so replaying batches in any delivery order reaches the same state. writeGeneration/updatedAt remain a local storage watermark and are deliberately not used as the comparator (they are not comparable across replicas).

  • Durable tombstones. Deletes are versioned states retained in sync_row_state, so a stale upsert pulled later cannot resurrect a row a newer delete removed.

  • Provenance. source, sourceDetail, createdByAgentId, projectId, and sessionId let a merge attribute and scope rows.

A first version therefore replicates at the observation row granularity with no migration of existing data: identity, version, and tombstone state all live in the additive sync_row_state / sync_meta tables.


4. Proposed architecture

4.1 Two layers
  1. A change journal (local). A small append-only log of committed mutations keyed by table + row id + logical version. This can be derived from existing columns for observations in v1, and generalized to other tables later. The journal is what gets shipped, so sync never has to diff the whole 900 MB database.

  2. A replication transport (remote). A narrow interface that can push local journal segments and pull remote ones. The store never talks to a vendor directly; it talks to this interface.

4.2 Transport interface (provider-agnostic)
// Final interface (src/sync/types.ts). The cursor maps deviceId -> last applied
// sequence locally; the page token is an opaque keyset continuation for one
// bounded pull.
interface SyncRemote {
  readonly kind: string;                 // "fs" | "github" | "s3" | "postgres"
  readonly namespace: string;
  init(options?: { create?: boolean }): Promise<void>;
  push(batch: ChangeBatch): Promise<void>;            // idempotent by (deviceId, sequence)
  pull(since: Record<string, number>, limit: number, pageToken?: string): Promise<SyncPullPage>;
  compact(through: Record<string, number>, options?: { dryRun?: boolean }): Promise<SyncCompactReport>;
  close(): Promise<void>;
}

Concrete adapters implement SyncRemote only:

  • fs/rsync — a directory the user already syncs by other means; zero new infrastructure, good for a first, fully local test.

  • github — an optional private-repository JSONL relay; it is convenient for a small personal store, not a database.

  • s3 — any S3-compatible object store; batches are immutable objects under a project path and optional user prefix.

  • postgres — a batch-log hub for users who already operate Postgres.

The point is that no adapter is privileged. Provider choice is configuration, not code, mirroring how [memory.llm], [embedding], and rerank already select providers by config.

4.3 Merge strategy
  • Row-level last-writer-wins, merged by the stable syncKey and versioned by the per-row logical clock (revision, writer). The comparison is a strict total order, so the merge is convergent: any delivery/replay order of the same batches yields the same final state.

  • No lifecycle special-casing. An earlier design ordered status transitions in lifecycle rank; that made the merge order-dependent (applying active@rev2 then archived@rev1 diverged from the reverse). Revision ordering alone already prevents a stale active copy from overriding a newer supersession/archival, so the guard was removed in favour of provable convergence.

  • Durable tombstones. A delete is a versioned state kept in sync_row_state, so a delete on machine A is never resurrected by machine B's stale upsert — even when B pulls the old upsert after the delete.

  • Preview-first: sync --dry reports the exact set of inserts, updates, supersessions, and tombstones that would apply, consistent with the existing preview-first maintenance actions.

4.4 Configuration surface (illustrative)
[sync]
enabled = false          # opt-in; default off
provider = "fs"          # fs | s3 | edge-kv | ...
mode     = "manual"      # manual | interval
# provider-specific settings live under a provider table, e.g. [sync.s3]
# credentials come from the environment, never from this file

Credentials and endpoints are resolved from the environment (as LLM/embedding keys already are), never written into a config file that could be shared.

4.5 CLI surface (illustrative)
  • memorix sync push / memorix sync pull / memorix sync status

  • memorix sync --dry for a preview before applying

  • Optional background interval sync gated behind [sync].mode = "interval"

Note: memorix sync today handles cross-agent rules synchronization (src/cli/commands/sync.ts). Store replication must not collide with that surface; it should live under a clearly separated subcommand namespace (for example memorix sync store ...) or a new top-level verb, decided by the maintainer.


5. Phasing

  1. Phase 1 — journal + local relay, observations only. Complete. Two real SQLite data directories reconcile through a shared filesystem relay, with project scope, privacy filtering, merge, delete, and clone protection.

  2. Phase 2 — remote relays + preview. Complete as a contract and adapter test slice. GitHub, S3-compatible, and Postgres transports are opt-in; provider credentials and live service acceptance remain deployment work.

  3. Phase 3 — snapshots and broader tables. Future. The current release does not replicate sessions, knowledge, CodeGraph, or encrypted snapshots.

  4. Phase 4 — background sync. Future. Manual status/push/pull remains the deliberate first user experience until recovery, privacy, and lifecycle telemetry are proven.

Each phase is independently useful and independently reviewable.


6. Compatibility and safety

  • Default off. Users who never enable [sync] see no behavior change.

  • No hot-path cost. Sync runs asynchronously; local reads/writes are unchanged.

  • No new required dependency. The fs adapter needs nothing; object-store and edge adapters are optional.

  • Local-first preserved. Every machine keeps a complete local store and works offline.

  • Preview-first and auditable, matching the existing maintenance model.


7. Open questions for maintainer direction

  1. Subcommand placement: extend sync (sync store ...) vs. a new top-level verb, given sync already means rules sync.

  2. Journal representation: derive from existing columns for v1, or add an explicit change-log table from the start.

  3. Which adapters belong in-tree vs. as optional/companion packages.

  4. Whether serve-http should be able to act as a sync remote for a user's own machines, giving a self-hosted option that still keeps each client local.

  5. Merge policy defaults: is row-level LWW acceptable as the v1 default, with lifecycle-aware overrides, or is a stricter policy preferred?

The first implementation slice is released behind the opt-in CLI. It covers the project-scoped observation event path, filesystem/GitHub/S3/Postgres relay contracts, local outbox retry, clone detection, conflict evidence, and bounded keyset pulls. It does not enable background sync, upload private memory, replicate sessions/knowledge/CodeGraph tables, or claim that GitHub is a production database.

  • Local-first: the memory stays in files or a database on your own machine (a rule-derived fact from the brain’s files, evidence: README.md)
  • Works with 14 MCP clients (a rule-derived fact from the brain’s files, evidence: README.md)
  • Open licence (Apache-2.0) (a rule-derived fact from the brain’s files)

Limitations

  • Needs an API key (ANTHROPIC_API_KEY, API_ROUTE_API_KEY, ATLASCLOUD_API_KEY) (a rule-derived fact from the brain’s files, evidence: README.md)
  • Needs a database (LanceDB, PostgreSQL, SQLite) (a rule-derived fact from the brain’s files, evidence: README.md)
  • Runs code automatically: review what it runs before you open it (a rule-derived fact from the brain’s files)
  • No ZIP download: install it from its source (a rule-derived fact from the brain’s files)
