Continuity Kernel

When to use this skill

Use this skill when the user wants to:

• Inject bounded continuity context into llm_input without manual configuration
• Persist Soul Card + Mission Ticket state with deterministic runtime contracts (durable default SQLite path, zero-config)
• Keep agent behavior fail-open if continuity logic or storage has an error
• Generate reproducible runtime proof receipts for audits and reviews
• Run shadow-mode evals and append chunk-level quality snapshots

Commands

# Run full test suite
python3 -m unittest discover -s tests/continuity-kernel -p 'test_*.py'

# Generate deterministic runtime contract proof artifact
python3 skills/continuity-kernel/generate_runtime_contract_proof.py

# SC-02 core-shadow gate (trace optional, synthetic allowed for this suite)
python3 skills/continuity-kernel/run_shadow_eval.py --layer 'Soul Card' --chunk 'SC-02' --suite core-shadow --runs 100 --append artifacts/continuity-kernel/p0-evals.json

# SC-02 perturb robustness gate (trace-backed, deterministic selector + size_only)
python3 skills/continuity-kernel/run_shadow_eval.py --layer 'Soul Card' --chunk 'SC-02' --suite memoryarena-mini-perturb --perturb-profile deletion --selector-mode deterministic --compaction-policy size_only --runs 100 --trace-jsonl tests/continuity-kernel/fixtures/shadow_eval_trace_memoryarena_mini_perturb.jsonl --append artifacts/continuity-kernel/p0-evals.json

# SC-02 perturb robustness gate (trace-backed, dual-route + attention-preserving)

Options

run_shadow_eval.py options:

• --layer TEXT — Active P0 layer name
• --chunk TEXT — Active chunk id/name
• --suite core-shadow|memoryarena-mini|memoryarena-mini-perturb — Task suite for eval scoring
• --perturb-profile none|deletion|noise_injection|reorder — Deterministic perturb profile for memoryarena-mini-perturb
• --selector-mode deterministic|dual_route_experimental — Selector mode tag for A/B eval receipts
• --compaction-policy size_only|attention_preserving_experimental — Compaction policy label for dropped-field A/B eval comparison
• --runs N — Number of evaluated shadow runs (default: 100)
• --trace-jsonl PATH — JSONL file containing observed shadow outcomes (repeatable)
• --trace-dir PATH — Directory scanned for *.jsonl observed shadow outcomes (repeatable)
• --append PATH — JSON file path to append snapshot results
• --allow-synthetic — Permit synthetic fallback for non-core suites when traces are unavailable (forced pass=false)
• --artifacts-root PATH — Directory for summary receipts (default: ~/.cache/continuity-kernel/p0-evals)

Runtime persistence defaults:

• ContinuityHookAdapter() uses ~/.local/state/continuity-kernel/continuity.db
• Override default path with CONTINUITY_KERNEL_DB_PATH
• Use :memory: only as explicit opt-in test mode
