Validate consensus summaries, enforce replay/keys, add experiments/tools/tests

[pdxvoiceteacher]

Motivation

• Harden submission ingest by validating consensus summary schemas (v1/v2), detecting expired/replayed or revoked/unknown key IDs, and scaffolding future enforcement.
• Prevent governance coupling to cognition artifacts by explicitly ignoring them during ingest while recording artifact boundary information.
• Add experiments and demo tooling to exercise Lambda spike and no-teleport checks and provide canonical fixtures for testing.

Description

• Implemented consensus handling and replay protection in tools/telemetry/ingest_submission.py including validate_consensus_summary, inspect_consensus_key_id, _bundle_hash, _check_replay_window, is_consensus_v2_expired, known/revoked key lists, a 24h REPLAY_WINDOW, and artifact boundary inspection that ignores cognition_ artifacts.
• Extended ucc runtime behavior in ucc/src/ucc/core.py to populate context["metrics"] from ingest_json input and to default sections_key for coherence_audit steps.
• Added tests and fixtures for consensus routing and ingest: new tests tests/test_consensus_schema_routing.py, tests/test_ingest_consensus_smoke.py, and tests/test_ingest_ignores_cognition_artifacts.py plus multiple consensus fixture JSON files.
• Added experiment configs, tasks, and small tools: experiments/* modules and inputs, tools/telemetry/generate_lambda_spike.py, tools/telemetry/demo_no_teleport.py, new example submission examples/submission_lambda_spike with artifact drift_series.json, and ucc task ucc/tasks/experiments/lambda_spike_task.json.
• Updated CI workflow .github/workflows/ingest_smoke.yml to install test deps and run the new consensus/ingest tests; cleaned minor .gitignore and normalized example JSON formatting.

Testing

• Ran the new unit tests with python -m pytest -q tests/test_consensus_schema_routing.py tests/test_ingest_consensus_smoke.py tests/test_ingest_ignores_cognition_artifacts.py and they passed.
• CI workflow updated to install dependencies and execute the above pytest invocation as part of the ingest smoke job (tests included in workflow).
