wrapper-guard: remove quotes instead of splitting on them; last name consumer
Round-five remediation of both blockers gate-ultron-01 raised on df83a9ee.
Measured against that head first; all eight returned rc=0 and each executes
the program the check exists to recognize:

    cu"rl" --config /tmp/w.cfg               -> allowed
    cu'rl' --config /tmp/w.cfg               -> allowed
    /usr/bin/cu\rl --config /tmp/w.cfg       -> allowed
    g"h" api -X POST repos/a/b/issues …      -> allowed
    /usr/bin/g\h api -X POST repos/a/b/… …   -> allowed
    curl --con"fig" /tmp/w.cfg               -> allowed
    /usr/bin/gh api -X POST repos/a/b/$EP …  -> allowed
    g"h" api -X POST repos/a/b/$EP …         -> allowed

BLOCKER 1. The previous commit said names are recognized "after quote
removal" and did not do that. It replaced quote characters with whitespace,
which is token SEPARATION: a shell removes a quote WITHOUT splitting the
word around it, so `cu"rl"` is one word naming curl, while whitespace made
it two words naming neither. `"/usr/bin/curl"` blocked under that version
only because the inserted space happened to land after a slash — a passing
case that established nothing about quote removal, and I read it as
confirmation. The characters are now DELETED, which is what quote removal
is. Backslashes go with them, because escaping is ordinary word formation
too. Deletion still handles substitution: `$(which curl)` becomes
`which curl`, where the name is a word on its own.

The flag is read from the same normalized copy for the same reason —
`--con"fig"` is one word spelling --config. No review raised that; the name
was simply the easier half to reach, and reading both halves the same way
is the entire point of having one normalization.

BLOCKER 2. A THIRD name consumer never went through the shared site: the
unreadable-endpoint arm kept a private bare-name copy of the scope gate's
regex against raw $CMD. A caller could be admitted by the repaired gate and
then go unrecognized by the fail-closed refinement — a gate and its own
refinement disagreeing about who the caller is, which is the defect one
layer downstream.

Fixing that surfaced the same mistake a third time inside this very edit:
my first version left the NAME in the refinement's tail regex, so the name
gate recognized `g"h" api` while the tail still demanded the undressed
spelling, and the two halves disagreed exactly as before. Caught by the
fixture, not by reading. Each half now asks one question: the name gate
asks WHO, from the normalized copy; the tail asks whether the ENDPOINT is
readable, from the raw text — deliberately raw, because the expansion
markers that make an endpoint unreadable are the characters the normalized
copy removes, and reading the tail from it would erase the evidence.

Controls: the 8 positive fixtures FAIL at df83a9ee and pass here; the
negatives — mycurl, curl-wrapper, mygh, mygh with an assembled endpoint, an
absolute-path read, and -K on a non-curl — pass at BOTH heads. Suite
166/166.

Unchanged and still stated in the comment rather than this message: a name
ABSENT from the text, assembled from variables or reached through a wrapper
script that execs the program, is invisible to any of this.

@mosaicstack/mosaic

CLI package for the Mosaic self-hosted AI agent platform.

Usage

mosaic wizard           # First-run setup wizard
mosaic gateway install  # Install the gateway daemon
mosaic config show      # View current configuration
mosaic config hooks list  # Manage Claude hooks

Headless / CI Installation

Set MOSAIC_ASSUME_YES=1 (or ensure stdin is not a TTY) to skip all interactive prompts. The following environment variables control the install:

Gateway configuration (mosaic gateway install)

Variable Default Required
MOSAIC_STORAGE_TIER local No
MOSAIC_GATEWAY_PORT 14242 No
MOSAIC_DATABASE_URL (none) Yes if tier=team
MOSAIC_VALKEY_URL (none) Yes if tier=team
MOSAIC_ANTHROPIC_API_KEY (none) No
MOSAIC_CORS_ORIGIN http://localhost:3000 No

Admin user bootstrap

Variable Default Required
MOSAIC_ADMIN_NAME (none) Yes (headless)
MOSAIC_ADMIN_EMAIL (none) Yes (headless)
MOSAIC_ADMIN_PASSWORD (none) Yes (headless)

MOSAIC_ADMIN_PASSWORD must be at least 8 characters. In headless mode a missing or too-short password causes a non-zero exit.

Example: Docker / CI install

export MOSAIC_ASSUME_YES=1
export MOSAIC_ADMIN_NAME="Admin"
export MOSAIC_ADMIN_EMAIL="[email protected]"
export MOSAIC_ADMIN_PASSWORD="securepass123"

mosaic gateway install

Runtime launchers

mosaic claude            # Launch Claude Code with Mosaic injection
mosaic yolo claude       # …with --dangerously-skip-permissions
mosaic codex | opencode | pi

mosaic claudex (EXPERIMENTAL)

Runs GPT models inside the Claude Code harness by pointing Claude Code at a local claude-code-proxy that translates the Anthropic Messages API to a ChatGPT-subscription (Codex OAuth) backend. This is not Anthropic Claude — model behavior, tool use, and output quality may differ. Intended for evaluation, not production delivery.

mosaic claudex           # launch (prompts through the proxy readiness gate)
mosaic yolo claudex      # …with --dangerously-skip-permissions
mosaic claudex --print "hello"   # trailing args are forwarded to Claude Code

Prerequisite: the claude-code-proxy binary must be installed and authenticated (claude-code-proxy codex auth …). mosaic claudex runs a preflight that verifies the binary, the OAuth state (triggering a device re-auth if needed), and a trusted local listener before launching; it fails closed if the proxy cannot be brought up with a verified identity.

Isolation (never touches your real Claude state). claudex always launches against an isolated CLAUDE_CONFIG_DIR (default ~/.config/mosaic/claudex/home). The ambient CLAUDE_CONFIG_DIR is deliberately ignored, and a guard proves the resolved dir can never be — or live under — the real ~/.claude. A claudex session therefore cannot mutate your normal Claude Code config.

No token leakage. claudex never reads the proxy's credential file. Claude Code is handed only ANTHROPIC_AUTH_TOKEN=unused pointed at the loopback proxy; the entire credential-bearing env family (ANTHROPIC_*, AWS_*, GOOGLE_CLOUD_*, GOOGLE_APPLICATION_CREDENTIALS, *_TOKEN, *_KEY, *_SECRET, …) is stripped from the composed environment. The Bedrock/Vertex routing switches (CLAUDE_CODE_USE_BEDROCK, CLAUDE_CODE_USE_VERTEX, and the _SKIP_*_AUTH pair) are force-removed regardless of value — otherwise their mere presence would route Claude Code to the real Anthropic API via AWS/GCP and bypass the proxy. The proxy holds the real OAuth credential.

Model tiers (override via env).

Tier Env var Default
primary (opus/sonnet) ANTHROPIC_MODEL gpt-5.6-sol
small/fast (haiku) ANTHROPIC_SMALL_FAST_MODEL gpt-5.6-luna

Operator-provided values win over the defaults. Additional overrides: MOSAIC_CLAUDEX_CONFIG_DIR (isolated config dir), ANTHROPIC_BASE_URL (proxy endpoint).

Hooks management

After running mosaic wizard, Claude hooks are installed in ~/.claude/hooks-config.json.

mosaic config hooks list              # Show all hooks and enabled/disabled status
mosaic config hooks disable PostToolUse  # Disable a hook (reversible)
mosaic config hooks enable PostToolUse   # Re-enable a disabled hook

Set CLAUDE_HOME to override the default ~/.claude directory.
