ci/woodpecker/pr/ci Pipeline is pending approval
Answers the review on #1228. Each item below was measured against the pre-change code, and where the review's stated consequence did not reproduce, that is recorded rather than repeated. BLOCKER -- `mapfile` is a Bash 4 builtin and macOS ships Bash 3.2, which this installer supports (node_platform names Darwin). newest_matching_file was therefore unavailable on macOS, and an empty answer is exactly what sends the uninstaller down its delete-the-destination branch. The lookup no longer renders candidates as text at all: the glob output is compared in-shell by mtime, via a stat helper that probes for GNU -c vs BSD -f once. That removes the Bash 4 dependency, the `ls | head` SIGPIPE failure, and the newline-splitting bug together, because all three came from turning filenames into lines. The function now distinguishes three outcomes instead of two: found, nothing matched, and could-not-tell. Callers act destructively on the answer, so the third case had to stop being indistinguishable from the second. The uninstaller leaves the file in place on an unanswerable lookup, and the manifest builder refuses to record a null backup it cannot vouch for. HIGH -- writing ~/.profile does not reach the shells that matter. A bash login shell reads the first of .bash_profile / .bash_login / .profile that exists and never looks at the rest, so on a host with either of the first two the entry was a silent no-op; a non-interactive remote zsh reads .zshenv and neither .zprofile nor .zshrc, which is what the previous version wrote; and a systemd --user unit reads no shell file at all, which is how a Mosaic agent seat starts. All four are now covered, with .bash_profile and .bash_login appended to only when they already exist -- creating one would itself start shadowing .profile. The systemd case is an environment.d drop-in. MEDIUM -- the checksum lookup interpolated the filename into a grep pattern. A Node tarball name is mostly dots, and a dot matches any character, so a manifest line for a different-but-regex-equivalent name was accepted as this file's checksum. Confirmed against the old function: it accepted the decoy. Filenames are now compared exactly, every line is read so a duplicate entry is refused rather than silently resolved, and the digest must look like a SHA-256. MEDIUM -- the PATH line is executed by every future shell that reads the file, and the directory was interpolated unescaped. A path containing shell syntax is now refused with a message instead of written. MEDIUM -- the idempotence check was an unanchored substring match, so a commented-out example of the same export made the installer skip the real entry. Reproduced against the old function, and now anchored with grep -Fqx. MEDIUM -- MOSAIC_NODE_DIST accepted any scheme. https:// and file:// only. The narrower point in the review stands and is not fixed by this: when the dist is overridden, the tarball and the checksum that vouches for it come from the same place, so the gate is integrity and not authenticity. HIGH, with a correction -- MOSAIC_NODE_VERSION is now validated before it becomes a path, but the review's specific consequence does not reproduce. `rm -rf` on a path ending in `..` is refused by rm itself, and a traversal version mangles the download URL so the run dies at curl long before the removal. Both were measured. The check is defence in depth and a clearer error, not a demonstrated hole being closed. Also removed a second `| head -1` in node_resolve_version, the same SIGPIPE shape as the one this PR already fixed, and the index result is validated before it becomes a path. Tests. The review was right that several existing cases passed on the unpatched code. The version-selection case now lists a higher major first and an older release of the right major after the right answer, so "first entry" and "last match" both fail it. The PATH case starts a real login shell and asks it to resolve node, rather than grepping for text the installer just wrote. The checksum-failure case asserts nothing survives, including the staging directory. New cases cover the empty manifest, the regex-equivalent decoy, the duplicate entry, the invalid version, the non-https dist, the shell-syntax path, the commented-out profile line, the .bash_profile shadow, and the environment.d drop-in. Each new case was run against the pre-change installer: the decoy, the commented-out line, the .bash_profile shadow and environment.d all go red there, which is the evidence that they test something. Bash 3.2 cannot be executed here, so the portability guard is a lint over install.sh for Bash 4 syntax. It is a weaker instrument than a run and is not claimed otherwise -- but every Bash 4 construct that has broken macOS in this file was added by someone who was not running it there either. test:installer passes.
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
curl -fsSL https://mosaicstack.dev/install.sh | bash
Or use the direct URL:
bash <(curl -fsSL https://git.mosaicstack.dev/mosaicstack/stack/raw/branch/main/tools/install.sh)
The installer auto-launches the setup wizard, which walks you through gateway install and verification. Flags for non-interactive use:
bash <(curl -fsSL …) --yes # Accept all defaults
bash <(curl -fsSL …) --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 |
Build-from-source at next |
| 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 is shorthand for the prerelease integration lane: it enables source-build mode and uses next unless an explicit --ref or MOSAIC_REF is provided.
After install, the wizard runs automatically or you can invoke it manually:
mosaic wizard # Full guided setup (gateway install → verify)
Requirements
- Node.js ≥ 22
- npm (for global @mosaicstack/mosaic install)
- One or more runtimes:
Usage
Launching Agent Sessions
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
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
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 for multi-user and production deployments, or Migrating to Federated to upgrade from existing tiers.
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
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

# 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
# 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

Consent state is persisted in config. Remote upload is a no-op until you run mosaic telemetry opt-in.
Development
Prerequisites
- Node.js ≥ 22
- pnpm 10.6+
- Docker & Docker Compose
Setup
git clone [email protected]: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
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:migratewithDATABASE_URLagainst 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",.jsextensions 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 installer again — it handles upgrades automatically:
curl -fsSL https://mosaicstack.dev/install.sh | bash
Or use the direct URL:
bash <(curl -fsSL https://git.mosaicstack.dev/mosaicstack/stack/raw/branch/main/tools/install.sh)
Or use the CLI:
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 tools/install.sh --check # Version check only
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: source build from next
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.
