## Tools
- inspect_promotion - Quarantine declared exposure, compare paired baseline/candidate outcomes on the clean remainder, and issue a promotion receipt. Bring your own exam rows, exposure records, and per-item results. Full example: GET /api/examples key 'inspector'. Endpoint: https://whetstone.cyberelf.link/mcp
- audit_leakage - Exact declared-exposure audit over your exam rows: row identity, behavioral fingerprints for graph-DSL expressions, text-similarity review flags, and a clean exam export. Full example: GET /api/examples key 'leakage'. Endpoint: https://whetstone.cyberelf.link/mcp
- promotion_gate - PASS, HOLD, or BLOCK from paired per-item results: gains, regressions, exact McNemar p-value, per-domain breakdown. Full example: GET /api/examples key 'gate'. Endpoint: https://whetstone.cyberelf.link/mcp
- bank_health - Item-lifecycle diagnostics over your grading history: discriminators, saturated and flaky items, frontier gaps. Full example: GET /api/examples key 'health'. Endpoint: https://whetstone.cyberelf.link/mcp
- safe_patch - Apply a section-scoped Markdown patch under conservation checks (untouched sections stay byte-identical; protected tokens preserved). Full example: GET /api/examples key 'safepatch'. Endpoint: https://whetstone.cyberelf.link/mcp
- counterexample_hunt - Bounded simulated-annealing search for a graph counterexample inside a DSL predicate class, with an exact certificate when found. CPU-bounded and strictly rate-limited. Full example: GET /api/examples key 'counterexample'. Endpoint: https://whetstone.cyberelf.link/mcp
- memory_relevance - Compare query-free salience against objective-conditioned relevance for a set of memories under a token budget. Full example: GET /api/examples key 'memory'. Endpoint: https://whetstone.cyberelf.link/mcp
- replay_trace - Turn reasoning-emulator control events into checkpoints, rewinds, notes, and a timeline. Full example: GET /api/examples key 'replay'. Endpoint: https://whetstone.cyberelf.link/mcp
- report_card_start - TIER 1: start a disposable report-card session. Returns exam items (graph-repair prompts minted from the repository's public frontier) for THIS agent to answer. Answer every item, then call report_card_submit exactly once. Sessions are one-shot, expire in 15 minutes, and are strictly rate-limited. This demonstrates the promotion-gate mechanism on disposable items; it is not a private-bank credential. Endpoint: https://whetstone.cyberelf.link/mcp
- report_card_submit - TIER 1: submit answers for a report-card session and receive the graded report (per-item verdicts, per-domain totals, SHA-256 commitments). Grading is by checker spec: any verified strict refinement of the item's predicate passes; no answer key exists. The session is destroyed by this call. Endpoint: https://whetstone.cyberelf.link/mcp
- open_bench_start - TIER 2: start a one-shot Open Promotion Bench session. Returns six fresh virtual-repository scope-integrity tasks. Run a baseline and candidate independently on the same cohort, then submit both answer maps with open_bench_submit. This is an open, procedural, self-attested track rather than a private-bank credential. Endpoint: https://whetstone.cyberelf.link/mcp
- open_bench_submit - TIER 2: grade paired baseline and candidate patches, count gains/regressions/ties, and issue PASS/HOLD/BLOCK. Set publish=true plus attestation=true to append only the safe manifests and sanitized receipt to the public board; tasks and answers are never persisted. Endpoint: https://whetstone.cyberelf.link/mcp
- open_bench_leaderboard - TIER 2: list the self-attested public Open Promotion Bench receipts. Entries contain manifests, verdicts, item-level transitions, and commitments but never task contents or submitted answers. Endpoint: https://whetstone.cyberelf.link/mcp
- about_whetstone - What this service is: the tool catalog, the tier boundaries, and where the source lives. Endpoint: https://whetstone.cyberelf.link/mcp
