📦 Source in repository (JSON)

Answer 1

I diagnosed the problem against the real artifact (chimera-deliberation==0.2.6, downloaded from PyPI), reproduced the failure, built the fix, and verified it end‑to‑end. The full write‑up is here:

~/ci-gate-untracked-config-solution.md

Root cause

Two independent defects combine:

  1. The gate spawned the MCP child in the repo root. chimera.yaml is gitignored by design, so load_config() raised FileNotFoundError; chimera/mcp/server.py::run() catches it and silently falls back to ChimeraConfig(defaults=Defaults.empty()). With cfg.formations == {}, chimera_deliberate("simple") returns {"error": "unknown_formation", "available": []} before any provider call — a valid-looking payload in ~1 s. The gate read that as a product defect.
  2. The workflow referenced a repository secret that never existed. GitHub expands a missing secret to "" with no warning, so that leg also ran keyless.

Fix (three parts, all in the doc)

  1. scripts/probe_mcp_stdio.py now provisions its own config by running the artifact's own chimera config init in a temp dir, pins CHIMERA_CONFIG, and prints CONFIG_SOURCE/CONFIG_PATH.
  2. It derives satisfiability from the environment using the artifact's build_preset_dag + provider_credential_resolved/credentialed_enabled_models, remaps unresolved models (printing each MODEL_SUBSTITUTION=...), and emits PROBE SKIP (exit 0) when nothing resolves — then asserts real provider activity (PROBE_TOKENS).
  3. tests/test_workflow_secrets.py is the offline recurrence guard: it parses every workflow and asserts each secrets.X is in a documented allowlist.

Verification actually performed

Check Result
Old behavior from empty dir unknown_formation, available: [], 0.73 s, no network
Fixed, no credentials PROBE SKIP, exit 0
Fixed, working provider (mock OpenAI server) MODEL_SUBSTITUTION lines + PROBE_TOKENS=48 + PROBE OK, exit 0
Fixed, rejected credential PROBE FAIL with real 401 provider traffic, exit 1
Secret guard on a workflow with secrets.CHIMERA_LIVE_KEY FAILED test_every_workflow_secret_is_allowlisted
Guard removed / full offline suite 6 passed

All code snippets in the document are the exact files I executed.
