# Mosaic Stack

Self-hosted, multi-user AI agent platform. One config, every runtime, same standards.

Mosaic gives you a unified launcher for Claude Code, Codex, OpenCode, and Pi — injecting consistent system prompts, guardrails, skills, and mission context into every session. A NestJS gateway provides the API surface, a Next.js dashboard gives you the UI, and a plugin system connects Discord, Telegram, and more.

## Quick Install

```bash
d="$(mktemp -d)" && trap 'rm -rf "$d"' EXIT && curl -fsSL -o "$d/install.sh" https://git.mosaicstack.dev/mosaicstack/stack/raw/branch/main/tools/install.sh -o "$d/install.sh.sha256" https://git.mosaicstack.dev/mosaicstack/stack/raw/branch/main/tools/install.sh.sha256 && (cd "$d" && test -s install.sh && sha256sum -c install.sh.sha256 && bash install.sh)
```

The published installer body must be non-empty and match its versioned SHA-256
sidecar before it executes. A failed fetch, HTTP-200 empty body, or digest
mismatch is fatal. Because both files come from the same repository and trust
domain, this detects corruption or inconsistent publication—not repository or
server compromise. Independently signed release provenance is explicitly
deferred by the greenfield-install PRD.

The installer auto-launches the setup wizard, which walks you through gateway install and verification. Flags for non-interactive use:

```bash
(cd "$d" && bash install.sh --yes)                   # Accept all defaults
(cd "$d" && bash install.sh --yes --no-auto-launch)  # Install only, skip wizard
```

This installs both components:

| Component               | What                                                             | Where                |
| ----------------------- | ---------------------------------------------------------------- | -------------------- |
| **Framework**           | Bash launcher, guides, runtime configs, tools, skills            | `~/.config/mosaic/`  |
| **@mosaicstack/mosaic** | Unified `mosaic` CLI — TUI, gateway client, wizard, auto-updater | `~/.npm-global/bin/` |

### Install lanes

| Lane                     | Command                               | Use when                                              | Source                                                                                      |
| ------------------------ | ------------------------------------- | ----------------------------------------------------- | ------------------------------------------------------------------------------------------- |
| Stable                   | `bash tools/install.sh`               | You want the released Mosaic CLI/framework            | npm registry `@mosaicstack/mosaic@latest` + framework archive at `main`                     |
| Prerelease integration   | `bash tools/install.sh --next`        | You want the current `next` integration branch        | Exact `@next` CLI/gateway versions + pinned `next` framework commit; pinned-source fallback |
| Contributor/source build | `bash tools/install.sh --dev --ref X` | You are testing a branch before release; `--ref` wins | Build-from-source at the requested ref                                                      |

`--next` selects the prerelease integration lane. It installs the exact CLI/gateway versions resolved from the aligned `@next` tags, and pins the framework archive to the resolved `next` commit. If the registry path fails, it builds from that pinned source. An explicit `--ref` or `MOSAIC_REF` wins and selects source mode.

After install, the wizard runs automatically or you can invoke it manually:

```bash
mosaic wizard        # Full guided setup (gateway install → verify)
```

### Requirements

- Linux x86_64 with glibc (Debian is the greenfield CI platform; musl/Alpine, macOS, and ARM64 currently fail as unsupported)
- Node.js ≥ 20 and npm ≥ 9
- `bash`, `curl`, `git`, `python3`, `tar`, and standard core utilities (`awk`, `df`, `find`, `flock`, `grep`, `install`, `realpath`, `sed`, `sha256sum`, `stat`, `sync`)
- At least 256 MiB free disk and 1,000 free inodes at the npm prefix
- One or more runtimes: [Claude Code](https://docs.anthropic.com/en/docs/claude-code), [Codex](https://github.com/openai/codex), [OpenCode](https://opencode.ai), or [Pi](https://github.com/mariozechner/pi-coding-agent)

The installer evaluates canonical phases P0–P9 and does not print `Done.` unless every committed postcondition passes. A failed phase exits non-zero, names the phase, and points to its durable journal under `${XDG_STATE_HOME:-~/.local/state}/mosaic/install/`. See [Installer state machine and recovery](docs/guides/installer-state-machine.md).

## Usage

### Launching Agent Sessions

```bash
mosaic pi                    # Launch Pi with Mosaic injection
mosaic claude                # Launch Claude Code with Mosaic injection
mosaic codex                 # Launch Codex with Mosaic injection
mosaic opencode              # Launch OpenCode with Mosaic injection

mosaic yolo claude           # Claude with dangerous-permissions mode
mosaic yolo pi               # Pi in yolo mode
```

The launcher verifies your config, checks for `SOUL.md`, injects your `AGENTS.md` standards into the runtime, and forwards all arguments.

Pi launches default to a token-lean skill posture: `mosaic pi` passes `--no-skills` so Pi does not preload every global skill description into the system prompt. Use `MOSAIC_PI_SKILL_MODE=all mosaic pi` for the legacy all-skills catalog, or `MOSAIC_PI_SKILL_MODE=discover mosaic pi` to let Pi use its native settings/project skill discovery.

### TUI & Gateway

```bash
mosaic tui                   # Interactive TUI connected to the gateway
mosaic gateway login         # Authenticate with a gateway instance
mosaic sessions list         # List active agent sessions
```

### Gateway Management

```bash
mosaic gateway install       # Install and configure the gateway service
mosaic gateway verify        # Post-install health check
mosaic gateway login         # Authenticate and store a session token
mosaic gateway config rotate-token    # Rotate your API token
mosaic gateway config recover-token  # Recover a token via BetterAuth cookie
```

If you already have a gateway account but no token, use `mosaic gateway config recover-token` to retrieve one without recreating your account.

### Configuration

Mosaic supports three storage tiers: `local` (PGlite, single-host), `standalone` (PostgreSQL, single-host), and `federated` (PostgreSQL + pgvector + Valkey, multi-host). See [Federated Tier Setup](docs/federation/SETUP.md) for multi-user and production deployments, or [Migrating to Federated](docs/guides/migrate-tier.md) to upgrade from existing tiers.

```bash
mosaic config show           # Print full config as JSON
mosaic config get <key>      # Read a specific key
mosaic config set <key> <val># Write a key
mosaic config edit           # Open config in $EDITOR
mosaic config path           # Print config file path
```

### Management

```bash
mosaic doctor                # Health audit — detect drift and missing files
mosaic sync                  # Sync skills from canonical source
mosaic skill list            # Audit Claude skill registrations and conflicts
mosaic skill register <name> # Register one canonical skill with Claude Code
mosaic skill unregister <name> # Remove one Mosaic-owned Claude link
mosaic update                # Update CLI/framework and auto-register canonical skills
mosaic wizard                # Full guided setup wizard
mosaic bootstrap <path>      # Bootstrap a repo with Mosaic standards
mosaic coord init            # Initialize a new orchestration mission
mosaic prdy init             # Create a PRD via guided session
```

### Sub-package Commands

Each Mosaic sub-package exposes its API surface through the unified CLI:

```bash
# User management
mosaic auth users list
mosaic auth users create
mosaic auth sso

# Agent brain (projects, missions, tasks)
mosaic brain projects
mosaic brain missions
mosaic brain tasks
mosaic brain conversations

# Agent forge pipeline
mosaic forge run
mosaic forge status
mosaic forge resume
mosaic forge personas

# Structured logging
mosaic log tail
mosaic log search
mosaic log export
mosaic log level

# MACP protocol
mosaic macp tasks
mosaic macp submit
mosaic macp gate
mosaic macp events

# Agent memory
mosaic memory search
mosaic memory stats
mosaic memory insights
mosaic memory preferences

# Task queue (Valkey)
mosaic queue list
mosaic queue stats
mosaic queue pause
mosaic queue resume
mosaic queue jobs
mosaic queue drain

# Object storage
mosaic storage status
mosaic storage tier
mosaic storage export
mosaic storage import
# Schema migration is unavailable in this release. The current storage wrapper shells
# directly to `pnpm --filter @mosaicstack/db db:migrate`; it is legacy N-1,
# uncertified, and MUST NOT be invoked pending KBN-101-02/-03/-06/-08 activation.
# Future schema migration is non-operative: external bootstrap → TLS/roles → runner
# --run → runner --verify → readiness. Tier copy uses only the separately held secure
# migrate-tier route.
```

### Telemetry

```bash
# Local observability (OTEL / Jaeger)
mosaic telemetry local status
mosaic telemetry local tail
mosaic telemetry local jaeger

# Remote telemetry (dry-run by default)
mosaic telemetry status
mosaic telemetry opt-in
mosaic telemetry opt-out
mosaic telemetry test
mosaic telemetry upload        # Dry-run unless opted in
```

Consent state is persisted in config. Remote upload is a no-op until you run `mosaic telemetry opt-in`.

## Development

### Prerequisites

- Node.js ≥ 20
- pnpm 10.6+
- Docker & Docker Compose

### Setup

```bash
git clone git@git.mosaicstack.dev:mosaicstack/stack.git
cd stack

# Install dependencies. The local tier uses in-process PGlite; leave DATABASE_URL unset.
# The pnpm store defaults to $HOME/.local/share/pnpm/store. Override it without
# editing the checkout with NPM_CONFIG_STORE_DIR=$HOME/another-store if needed.
pnpm install

# Verify dependencies and generated state before running source-quality gates.
# Missing dependencies exit 42; stale/foreign apps/web/.next state exits 43.
# The web build certifies its exact standalone symlink manifest; added, removed,
# retargeted, or manifest-only-tampered generated links also exit 43. This detects
# accidental, independent, stale, and foreign-residue mutation—the class exposed by
# a five-month-stale .next that produced 19 phantom TS2307 errors.
# It does NOT defend against a same-UID actor that can rewrite both manifest and
# marker consistently (CWE-345). RM-59 tracks the required executor/spine-side
# trust anchor outside worktree authority.
pnpm preflight

# Optional local queue service only. This does not start PostgreSQL.
docker compose up -d valkey

# The current Gateway/Web local process is held; see docs/guides/dev-guide.md.
# Do not start it until KBN-101-02 makes inherited dotenv/DSN state fail closed.
```

### Held future procedure

The checked-in Compose PostgreSQL service mounts legacy initialization SQL and is **not** a
current PostgreSQL, standalone, or federated developer route. Do not start it with Compose,
invoke initialization SQL, or treat the planned migrator as currently executable.

**Held future activation procedure — non-operative and no current command authority until KBN-101-00, KBN-101-03, and KBN-101-05
land:** external bootstrap → TLS/roles → `mosaic-db-migrator --run` →
`mosaic-db-migrator --verify` → Gateway/Compose readiness. The future deployment artifacts—not
this README—will provide the reviewed commands and secret-consumer interface.

For local data-layer work, PGlite needs no PostgreSQL service. The optional Compose command above
starts only Valkey; OTEL Collector and Jaeger may likewise be started individually if needed,
without starting PostgreSQL. A Gateway/Web local process is not currently a safe PGlite route:
its unguarded dotenv loader may inherit a daemon PostgreSQL DSN. Do not use root `pnpm dev` or a
Gateway start command until KBN-101-02 makes that state fail closed.

### Quality Gates

```bash
pnpm preflight               # Checkout/dependency/generated-state validation
pnpm typecheck               # TypeScript type checking (all packages)
pnpm lint                    # ESLint (all packages)
pnpm test                    # Vitest (all packages)
pnpm format:check            # Prettier check
pnpm format                  # Prettier auto-fix
```

### CI

Woodpecker CI runs on every push:

- `pnpm install --frozen-lockfile`
- **Legacy N-1 CI status only — active, uncertified, and non-authorizing as an operator route:** the checked-in job currently invokes `pnpm --filter @mosaicstack/db run db:migrate` with `DATABASE_URL` against an isolated disposable PostgreSQL CI database. It performs direct DDL in that CI database, is not approved ordinary behavior or an operator route, and remains a known exception pending KBN-101-06 removal/replacement by the certified runner-backed CI path.
- `pnpm test` (Turbo-orchestrated across all packages)

npm packages are published to the Gitea package registry on main merges.

### Key Design Decisions

- **Gateway is the single API surface** — all clients (TUI, web, Discord, Telegram) connect through it
- **ESM everywhere** — `"type": "module"`, `.js` extensions in imports, NodeNext resolution
- **Socket.IO typed events** — defined in `@mosaicstack/types`, enforced at compile time
- **OTEL auto-instrumentation** — loads before NestJS bootstrap
- **Explicit `@Inject()` decorators** — required since tsx/esbuild doesn't emit decorator metadata

### Framework (`~/.config/mosaic/`)

The framework is the bash-based standards layer installed to every developer machine:

```
~/.config/mosaic/
├── AGENTS.md              ← Central standards (loaded into every runtime)
├── SOUL.md                ← Agent identity (name, style, guardrails)
├── USER.md                ← User profile (name, timezone, preferences)
├── TOOLS.md               ← Machine-level tool reference
├── bin/mosaic             ← Unified launcher (claude, codex, opencode, pi, yolo)
├── guides/                ← E2E delivery, orchestrator protocol, PRD, etc.
├── runtime/               ← Per-runtime configs (claude/, codex/, opencode/, pi/)
├── skills/                ← Universal skills (synced from agent-skills repo)
├── tools/                 ← Tool suites (orchestrator, git, quality, prdy, etc.)
└── memory/                ← Persistent agent memory (preserved across upgrades)
```

### Forge Pipeline

Forge is a multi-stage AI pipeline for autonomous feature delivery:

```
Intake → Discovery → Board Review → Planning (3 stages) → Coding → Review → Remediation → Test → Deploy
```

Each stage has a dispatch mode (`exec` for research/review, `yolo` for coding), quality gates, and timeouts. The board review uses multiple AI personas (CEO, CTO, CFO, COO + specialists) to evaluate briefs before committing resources.

## Upgrading

Run the same verified installer flow again — it handles upgrades automatically:

```bash
d="$(mktemp -d)" && trap 'rm -rf "$d"' EXIT && curl -fsSL -o "$d/install.sh" https://git.mosaicstack.dev/mosaicstack/stack/raw/branch/main/tools/install.sh -o "$d/install.sh.sha256" https://git.mosaicstack.dev/mosaicstack/stack/raw/branch/main/tools/install.sh.sha256 && (cd "$d" && test -s install.sh && sha256sum -c install.sh.sha256 && bash install.sh)
```

Or use the CLI:

```bash
mosaic update                # Check + install CLI updates
mosaic update --check        # Check only, don't install
```

The CLI also performs a background update check on every invocation (cached for 1 hour).

### Installer Flags

```bash
bash tools/install.sh --check           # Side-effect-free P0-P8 postcondition check
bash tools/install.sh --framework       # Framework only (skip npm CLI)
bash tools/install.sh --cli             # npm CLI only (skip framework)
bash tools/install.sh --next            # Prerelease lane: exact @next versions + pinned-source fallback
bash tools/install.sh --dev             # Contributor lane: source build at --ref/main
bash tools/install.sh --ref v1.0        # Install from a specific git ref (--ref wins over --next)
bash tools/install.sh --yes             # Non-interactive, accept all defaults
bash tools/install.sh --no-auto-launch  # Skip auto-launch of wizard
```

The installer rejects unrecognized flags or positional arguments before making changes and prints the supported-option usage. `--check` reports one PASS/FAIL row for each P0–P8 predicate and exits non-zero if any row fails; it does not create the npm prefix, lock, journal, manifest, or runtime files.

## Contributing

```bash
# Create a feature branch
git checkout -b feat/my-feature

# Make changes, then verify
pnpm typecheck && pnpm lint && pnpm test && pnpm format:check

# Commit (husky runs lint-staged automatically)
git commit -m "feat: description of change"

# Push and create PR
git push -u origin feat/my-feature
```

DTOs go in `*.dto.ts` files at module boundaries. Scratchpads (`docs/scratchpads/`) are mandatory for non-trivial tasks. See `AGENTS.md` for the full standards reference.
