From 7cdbe02286cb5ef46028becff3d9dd8a2e27c1cf Mon Sep 17 00:00:00 2001 From: Claude Date: Tue, 19 May 2026 01:19:29 +0000 Subject: [PATCH 01/13] auth: add HMAC + bearer-token primitives alongside Epistula MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit shared/auth.py keeps the existing Epistula sign_request / verify_request intact and adds four new primitives for the non-competitive cutover: * hmac_sign_request(secret, body, key_id) — outbound HMAC * hmac_verify_request(headers, body, key_lookup) — inbound HMAC * extract_bearer(headers) — pull bearer token * hash_api_key(key) — sha256 hex for DB * load_service_secret(env) — read RADAR_SERVICE_KEY * static_key_lookup(key_id, secret) — single-key lookup HMAC scheme: HMAC-SHA256 over "{timestamp}.{sha256(body).hex()}" with the body digest (not raw body) to bound input size. key_id travels in cleartext so the verifier can look up the right secret. Default timestamp tolerance is 5 minutes; tunable via RADAR_HMAC_TOLERANCE. 11 new tests in tests/test_auth_hmac.py cover roundtrip, tampering, wrong key, unknown key_id, stale timestamps, header completeness, and bearer/hash helpers. Existing callers (DatabaseClient, runner/server.py, validator paths) keep using the Epistula surface unchanged — the new surface is opt-in and lands as additive infrastructure for the non-competitive mode and the upcoming /miners/me/* API. --- shared/auth.py | 184 ++++++++++++++++++++++++++++++++++------ tests/test_auth_hmac.py | 127 +++++++++++++++++++++++++++ 2 files changed, 286 insertions(+), 25 deletions(-) create mode 100644 tests/test_auth_hmac.py diff --git a/shared/auth.py b/shared/auth.py index 258cf86..4a6ce3f 100644 --- a/shared/auth.py +++ b/shared/auth.py @@ -1,35 +1,50 @@ -"""Epistula authentication — sign and verify HTTP requests. +"""Auth primitives — both legacy Epistula and new HMAC/bearer surfaces. -Extracted from validator/gossip.py.

Round-robin selection (pick_for_round) so the agent's choice is deterministic given a round_id. Rollback + history listing. miner_template/optimizers/__init__.py Plugin contract: optimize(results, population, config) -> new_population Resolver accepts built-in aliases ("gepa", "random_mutate") or "package.module:func" paths. ResultRow dataclass wraps the row shape /miners/me/results will return. miner_template/optimizers/random_mutate.py Baseline, no-LLM optimizer. Ranks prompts by mean scores[score_key], promotes top-K elites, generates children via deterministic perturbation suffixes. Used in CI and as a fallback when DSPy isn't installed. miner_template/optimizers/gepa.py DSPy GEPA adapter. Lazy-imports dspy so the CLI works without it. Reflector LM resolves from MINER_REFLECTOR_* env first, then MINER_LLM_* operator-proxy env vars. Wraps each Prompt as a dspy.Signature with a custom instruction and runs the GEPA teleprompter; maps optimized programs back to Prompt rows with new UUIDs, bumped generation, and parent_id set from lineage. 40 new tests cover roundtrip, atomic writes, archive/rollback, deterministic round-robin, resolver edge cases, ranking, elite preservation, deterministic perturbation, and ResultRow parsing. GEPA itself is not unit-tested here (needs an LM); a gated integration test will land alongside the CLI wiring. --- miner_template/__init__.py | 12 ++ miner_template/optimizers/__init__.py | 97 +++++++++ miner_template/optimizers/gepa.py | 219 ++++++++++++++++++++ miner_template/optimizers/random_mutate.py | 115 +++++++++++ miner_template/prompts.py | 227 +++++++++++++++++++++ tests/test_optimizer_random_mutate.py | 108 ++++++++++ tests/test_optimizers_resolve.py | 61 ++++++ tests/test_prompts_store.py | 149 ++++++++++++++ 8 files changed, 988 insertions(+) create mode 100644 miner_template/__init__.py create mode 100644 miner_template/optimizers/__init__.py create mode 100644 miner_template/optimizers/gepa.py create mode 100644 miner_template/optimizers/random_mutate.py create mode 100644 miner_template/prompts.py create mode 100644 tests/test_optimizer_random_mutate.py create mode 100644 tests/test_optimizers_resolve.py create mode 100644 tests/test_prompts_store.py diff --git a/miner_template/__init__.py b/miner_template/__init__.py new file mode 100644 index 0000000..fc56542 --- /dev/null +++ b/miner_template/__init__.py @@ -0,0 +1,12 @@ +"""Miner template — starter agent + prompt-evolution scaffolding. + +The miner CLI (``miner/neuron.py``) drives this package's two surfaces: + + * ``agent.py`` — ``design_architecture(challenge, client)`` entrypoint + called by the validator each round. + * ``prompts`` + ``optimizers`` + ``results_client`` — feedback loop + that lets miners pull their own scored history and evolve their + agent's prompts (e.g. via GEPA). + +See ``docs/optimizer.md`` for the loop in full. +""" diff --git a/miner_template/optimizers/__init__.py b/miner_template/optimizers/__init__.py new file mode 100644 index 0000000..73f92cb --- /dev/null +++ b/miner_template/optimizers/__init__.py @@ -0,0 +1,97 @@ +"""Prompt-optimizer plugin registry for miners. + +A plugin is any callable with the signature:: + + optimize(results: list[ResultRow], + population: list[Prompt], + config: dict) -> list[Prompt] + +Built-ins: + ``random_mutate`` — deterministic baseline, no LLM required (CI-safe) + ``gepa`` — DSPy GEPA adapter (Genetic-Pareto reflective evolution) + +Custom optimizers can be referenced as ``"package.module:func"`` — +e.g. ``my_research.optimizers:my_optimizer`` — and ``resolve()`` will +import them on demand. +""" + +from __future__ import annotations + +import importlib +from dataclasses import dataclass, field +from typing import Callable, Optional + +from miner_template.prompts import Prompt + +# ── Public types ───────────────────────────────────────────────────── + + +@dataclass(slots=True) +class ResultRow: + """One scored submission, as returned by ``/miners/me/results``.""" + + round_id: int + submission_id: str + task_name: str + prompt_id: Optional[str] + architecture_code: str + scores: dict = field(default_factory=dict) + created_at: str = "" + + @classmethod + def from_dict(cls, d: dict) -> "ResultRow": + return cls( + round_id=int(d.get("round_id", 0) or 0), + submission_id=str(d.get("submission_id", "") or ""), + task_name=str(d.get("task_name", "") or ""), + prompt_id=d.get("prompt_id"), + architecture_code=str(d.get("architecture_code", "") or ""), + scores=dict(d.get("scores") or {}), + created_at=str(d.get("created_at", "") or ""), + ) + + +Optimizer = Callable[[list[ResultRow], list[Prompt], dict], list[Prompt]] + + +# ── Resolver ───────────────────────────────────────────────────────── + + +_BUILTINS = { + "random_mutate": "miner_template.optimizers.random_mutate:optimize", + "gepa": "miner_template.optimizers.gepa:optimize", +} + + +def resolve(name: str) -> Optimizer: + """Return the optimizer callable for ``name``. + + Accepts a built-in alias (``"gepa"``) or a fully qualified + ``"package.module:func"`` path. + """ + target = _BUILTINS.get(name, name) + if ":" not in target: + raise ValueError( + f"unknown optimizer {name!r}; expected one of {sorted(_BUILTINS)} " + f"or 'package.module:func'" + ) + module_path, func_name = target.split(":", 1) + try: + mod = importlib.import_module(module_path) + except ImportError as e: + raise ImportError( + f"optimizer {name!r}: cannot import {module_path!r}: {e}" + ) from e + try: + func = getattr(mod, func_name) + except AttributeError: + raise AttributeError( + f"optimizer {name!r}: {module_path}:{func_name} not found" + ) + if not callable(func): + raise TypeError(f"optimizer {name!r}: {target} is not callable") + return func + + +def list_builtins() -> list[str]: + return sorted(_BUILTINS) diff --git a/miner_template/optimizers/gepa.py b/miner_template/optimizers/gepa.py new file mode 100644 index 0000000..0918b23 --- /dev/null +++ b/miner_template/optimizers/gepa.py @@ -0,0 +1,219 @@ +"""GEPA — Genetic-Pareto reflective prompt evolution. + +Adapter around ``dspy.GEPA``.

When this validator published From 941789c05776e025b25b6850a0cb31ad989681d4 Mon Sep 17 00:00:00 2001 From: Claude Date: Tue, 19 May 2026 02:50:37 +0000 Subject: [PATCH 05/13] non-competitive mode: HMAC cutover, operator CLI, validator chain bypass MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Closes out the non-competitive plan: validator/trainer/DB auth switches from Epistula to HMAC + bearer when ``RADAR_NONCOMPETITIVE=true``, operators can register miners and rotate keys via a new CLI, and the trainer drops its bittensor/metagraph dependency entirely. Config (config.py): * RADAR_NONCOMPETITIVE false master toggle * RADAR_SERVICE_KEY "" shared HMAC secret * RADAR_SERVICE_KEY_ID "operator" key_id on the wire Validator hard-fails at boot if NONCOMPETITIVE=true with no SERVICE_KEY — no silent misconfigs. Validator (validator/neuron.py): * NONCOMPETITIVE branch: wallet/subtensor/metagraph stay None, DatabaseClient is built with service_secret instead of wallet. * Existing competitive path unchanged when the flag is false. Trainer (runner/server.py): * Dropped _load_metagraph, _metagraph_cache, METAGRAPH_REFRESH_*, bittensor lazy-import, asynccontextmanager preload hook. * /train now verifies HMAC against RADAR_SERVICE_KEY via shared.auth.hmac_verify_request + static_key_lookup; 503 if the env var is unset (fail-closed) rather than reaching for the chain. * Renamed _hotkey_lock / _hotkey_last_request -> _key_lock / _key_last_request to match the new identity model. * Localnet bypass preserved for dev (RADAR_LOCALNET=1). DB server (database/server.py): * auth_middleware now tries HMAC first (when RADAR_SERVICE_KEY is set), then falls back to the legacy Epistula path so dual-stack deployments work without flag churn. DB client (shared/db_client.py): * Constructor accepts service_secret (HMAC), api_key (bearer), or wallet (Epistula). Picks the right scheme in _sign(). Fails fast if none are supplied. * Renamed hotkey params -> miner_id on agent_code accessors. * New my_submissions / my_results / my_summary client methods for /miners/me/* — bearer-auth surface for operator-side tooling. Operator CLI (database/operator_cli.py): * python -m database.operator_cli register --name --hotkey --contact * python -m database.operator_cli issue-key --miner-id --scope --label (plaintext printed ONCE) * python -m database.operator_cli revoke-key --key-id * python -m database.operator_cli list-miners / list-keys * python -m database.operator_cli rotate-service-key (prints a fresh 64-hex key) Ensures the miners + miner_api_keys DDL exists on first use. Docs (CLAUDE.md): * New "Non-competitive Mode" section walking the operator + miner flows end to end. Tests (+22): test_runner_auth.py 7 HMAC reject paths, 503 when unset, /health open, localnet bypass, no-bittensor regression guard. test_operator_cli.py 9 parser shape, register/issue-key/ revoke dispatch, rotation output, list-keys table. test_config_noncompetitive.py 6 truthy/falsy parsing, service-key defaults + override. Total 131 passing in the new test surface (up from 109). Remaining as follow-ups (none block the GEPA loop): * Strip every bittensor reference from validator/neuron.py weight- setting + commitment paths — currently guarded by NONCOMPETITIVE. * Same for miner/neuron.py (still imports bt for the listener auth). * Delete shared/commitment.py + gossip routes once the chain code paths are gone. --- CLAUDE.md | 27 +++ config.py | 17 ++ database/operator_cli.py | 248 ++++++++++++++++++++++++++++ database/server.py | 30 +++- runner/server.py | 103 ++++-------- shared/db_client.py | 133 +++++++++------ tests/test_config_noncompetitive.py | 50 ++++++ tests/test_operator_cli.py | 147 +++++++++++++++++ tests/test_runner_auth.py | 105 ++++++++++++ validator/neuron.py | 35 +++- 10 files changed, 767 insertions(+), 128 deletions(-) create mode 100644 database/operator_cli.py create mode 100644 tests/test_config_noncompetitive.py create mode 100644 tests/test_operator_cli.py create mode 100644 tests/test_runner_auth.py diff --git a/CLAUDE.md b/CLAUDE.md index 75e3ff3..0223d86 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -259,6 +259,33 @@ add `HIPPIUS_*` once your Hippius keys are issued — the client will pick up the new backend automatically.

Hard error at construction time if NONCOMPETITIVE=false and bittensor isn't available, so misconfigs surface immediately rather than at first chain call. * get_config() returns a plain argparse.Namespace when NONCOMPETITIVE=true (or bt is None); only wires bt.Wallet / bt.Subtensor flags in competitive mode. * run_round() walltime branch: ``current_block = int(time.time()//12)`` so the deterministic round seed stays stable for ~12s like a block. set_metagraph(None) + set_hotkey_map({}) when chain is off. * _set_weights() short-circuits on NONCOMPETITIVE before touching subtensor.set_weights — no accidental chain writes from misrouted code paths. miner/neuron.py: * Same try/except import pattern, same get_config branching. * Miner.__init__ sets wallet/subtensor/metagraph = None in NONCOMPETITIVE mode; raises with a clear install hint in competitive mode if bittensor isn't installed. * Miner ctor no longer typed as ``bt.Config`` (would break import). 15 new regression tests (test_noncompetitive_gates.py): * runner/server.py has zero bittensor refs + no metagraph cache symbols * miner + validator neuron modules use the try/except import shape * get_config() takes the argparse path under NONCOMPETITIVE * _set_weights / run_round have the expected NONCOMPETITIVE gates * wallet/subtensor/metagraph stay None on the noncompetitive path * DatabaseClient constructor rejects no-auth, accepts each of service_secret / api_key / wallet, signs with the right scheme Total 146 passing across the non-competitive surface (up from 131). Known remaining: shared/substrate.py, validator/substrate_publisher.py, shared/commitment.py and friends still import bittensor at module top. Validator's transitive import graph therefore still needs bittensor installed even with NONCOMPETITIVE=true — but those modules' code paths are not called when the chain is off. Two ways to close: either lazy-import bittensor in each of those modules, or fork a ``validator/neuron_noncompetitive.py`` that imports a narrower set.

Wrapped with TYPE_CHECKING + a _bt() helper so the module loads in non-competitive deployments and only pulls bittensor in when ``verify_record`` actually runs the sr25519 signature check (i.e. on the competitive path). shared/substrate.py: * ``import bittensor as bt`` moved into ``if TYPE_CHECKING`` and a ``_bt()`` runtime helper that imports on first use. * ``verify_record`` calls ``_bt()`` inside the existing try/except so a missing bittensor surfaces as the same "signature verification failed" message rather than a hard ImportError at module load. Result: with ``RADAR_NONCOMPETITIVE=true``, every path from ``import validator.neuron`` down through substrate / substrate_publisher / commitment loads without bittensor on the box.
