ci/woodpecker/pr/ci Pipeline was successful
wrapper-guard: name the marker every forge API shares, not one dialect's
The scope gate asked for a scheme URL, a `/api/v[0-9]` path, or a provider-CLI
`api` subcommand. `/api/v[0-9]` is Gitea's spelling. GitHub's API carries no
version segment at all -- `api.github.com/repos/a/b/issues` -- so the schemeless
Gitea write was in scope and the schemeless GitHub one was not:

    curl -X POST -d x api.github.com/repos/a/b/issues              rc 0
    curl -X POST -d x api.github.com/repos/a/b/issues/1/comments   rc 0
    host=api.github.com; curl -X POST -d x ${host}/repos/a/b/issues rc 0

A gate calibrated to one provider's spelling rather than to what identifies a
provider API. `/repos/` is the marker both dialects share -- every forge API
addresses a repository through it -- so the gate now names both.

This is SPAN a third time, and the third layer it has appeared on. Round 8: a
block message named a wrapper that could not make the call. Round 9: a map
claimed a span its wrapper did not cover. Round 10: a control claimed a surface
it did not measure. Here the scope gate itself claimed a class of API and
recognised one member of it. Same question each time -- does this thing SPAN
what it claims -- and it has now been the answer four rounds running, which is
the argument for asking it of every arm rather than of the reported one.

Widening a scope gate can only make the guard stricter. Downstream a block still
requires a body flag AND either a mapped endpoint or an unreadable one, so this
widens what is CONSIDERED, not what is refused. The three fixtures asserting that
-- a schemeless GitHub read, an unwrapped GitHub endpoint, and a read past `--`
-- exist to hold that claim to account rather than state it.

Also: the provider-CLI arm's option scanner required a letter after the dashes,
so `gh api -X POST -- ${p}${q} -f title=x` walked its endpoint straight past.
The end-of-options marker is the one option not spelled like one, and a scanner
that skips options had to be told so.

Because the new endpoints are READABLE, each blocked fixture asserts the wrapper
its message must name. A rc-only fixture here would have passed on the unreadable
arm and proved nothing -- which is the failure mode this suite caught in itself
last round.

Evidence: 110/110 fixtures (was 101) locally and in ci-base. Negative-controlled
per change, not in aggregate: dropping `/repos/` from the gate fails exactly the
five GitHub fixtures; dropping the `--` alternative fails exactly one; neither
disturbs a pre-existing fixture. 18-command sweep unchanged (same three round-6
flips, nothing new); 12-command ordinary-work sweep 0 blocked. shellcheck clean
at warning+. CI 2374 on the previous head was green across all nine steps.

Residual, stated rather than implied: a caller who splits `/repos/` itself in a
schemeless GitHub URL leaves no literal marker anywhere and is out of scope --
the same boundary as splitting the hostname, and no longer a mistake anyone
makes by accident.

Round 11, addressing rev0 review 154.

@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.
