fred b91b702a53 fix(launch): drop the dead recordLaunch test seam; stop a load-sensitive spec reporting CPU load as a defect
Two changes, both about a test seam that alters production behaviour.

AMD1213-D defect D5 objected that `launchFleetRuntimeForTest` was an exported
production API that also set `recordLaunch:false`, changing a second production
branch beyond the two the card authorized. Most of that is already closed in
this tree: the exported helper is gone, and the specs now enter through the real
`registerFleetLaunchCommand -> apply -> launchFleetRuntime -> launchRuntime`
route on a fixture seat, with the ledger pointed at the fixture and asserted
(`fleet-launch-command.spec.ts` asserts `events.ndjson` contains the record).
The seat-seeded/HOME-empty pass and HOME-seeded/seat-empty fail pair both exist.

What remained was the `recordLaunch?: boolean` context field itself. Nothing in
the package sets it -- it is a dead switch whose only effect was to let a caller
silently disable launch recording on the claude branch while codex, opencode and
pi recorded unconditionally. Removed, so all four branches record the same way
and the asymmetry cannot be reintroduced by passing a flag.

The second change is unrelated to D1-D6 and is called out as such. It is here
because the amend's required evidence includes a green full-package Vitest run,
and one spec made that non-reproducible.

`install-ordering-guard.spec.ts` proves that `guardClaudeSettingsWiring` really
delegates to `leaseEnforcementActivatable()` by comparing the guard's outcome
against its own call to the same predicate. That predicate is not deterministic:
`defaultCapabilityProbe` runs `dist/cli.js` out-of-process with a 2000 ms
timeout. In a full-package run with 86 spec files scheduled at once, one
observation beats that timeout and the next does not, the two disagree, and the
test fails -- reporting machine load as a wiring defect. It passed in isolation
every time, which is why it read as a flake.

Measured rather than assumed. The failure reproduced in three consecutive full
runs and passed 3/3 in isolation. It was NOT caused by the recordLaunch removal
above: reverting only that edit and re-running the full suite still failed, which
is what ruled my own change out.

The guard call is now bracketed by two observations of the predicate, and only a
pair that agrees is used as ground truth; a disagreeing pair is retried, up to
three attempts, and never holding still is itself a failure rather than a skip.
This does not weaken the assertion -- a real delegation failure is stable and
survives every attempt while load noise is not.

Falsified: inverting the guard's default to `!leaseEnforcementActivatable()`
turns the test red (1 failed / 18 passed), so the retry did not blunt what the
test detects. The inversion was reverted and the file confirmed clean.

Verification: typecheck RC=0. Three consecutive full-package runs, RC=0,
86 files / 1619 tests passed, 0 failed, under the sanitized lease environment
(MOSAIC_LEASE_* and MOSAIC_RUNTIME_GENERATION stripped).

@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.
