From 98a96536e94be39e84f18cfd5bcdf71f8e7e1af8 Mon Sep 17 00:00:00 2001 From: echobt <154886644+echobt@users.noreply.github.com> Date: Sun, 18 Oct 2026 23:22:42 +0000 Subject: [PATCH 01/82] test: fast marker, check-fast.sh and CPU mining smoke under 2 minutes Add a `fast` marker assigned in tests/conftest.py from a file list (protocol, beacon, data, ledger, aggregator, trainer core, auditor, service contract and rounds, miner client), excluding four multi-second scale cases that add nothing to the mining path. scripts/check-fast.sh runs that subset with a 120 s budget and prints the measured wall time. scripts/mine-smoke.sh starts the real challenge app, one miner and one auditor through the e2e harness on the tiny CPU model (H=4, J=2) and fails unless the round reaches FINAL with a MATCH verdict inside the budget.

Status handling: 409 (conflicting round, never overwritten), 400 and any other 3xx/4xx exit 1 at once; 401/403 exit 2. 408, 429, 5xx, network errors and relay failures are counted and retried, exit 1 after --max-failures in a row. Relay disagreement surfaces as BeaconVerificationError from the frozen drand.py; it is retried like an outage instead of exiting, as decided by the founder: nothing unverified is ever pushed either way, and one bad relay should not kill the pusher. The admin token must match [A-Za-z0-9._~-]+. Those characters survive JSON escaping and URL encoding, so an echoed token in a service body is always caught by exact-match redaction (done before the 500-char cut), and httpx never quotes it in an illegal-header error. Base64 tokens are refused with exit 2 rather than redacted by a list of encodings. Tests use recorded quicknet rounds 1000000 and 1000001, so BLS verification is real, and no network.

Nothing in the tree produced them from a built shard set. pin re-verifies the shard set (verify_shards16 and the sample tree root against manifest.merkle_root), writes both objects into a LocalFSStore and prints the training.dataset fragment. --holdout-dir adds holdout_commit after checking the holdout shards and seq_len. register copies both objects into the service's local per-run store (state_dir/runs//objects), then sends PUT /admin/dataset with the admin bearer. The brief asked for an HTTP upload to PUT /v2/runs/{id}/objects/{sha}. That route only accepts a hotkey signature from a subnet-registered, run-admitted hotkey, not the admin bearer, and no such hotkey is available today. The founder chose the local copy, the path scripts/genuine_cuda_index.py already uses. Switch to the signed route once a hotkey exists. register refuses before any write when: - the run is the root-hosted first run; - the run id is not 64 hex characters; - the store belongs to another uid; - the token is not one line of printable ASCII (httpx echoes an illegal header value in its error, which would print the token). --sample-ids-file is not implemented: the service rejects any samples or proofs object that does not cover all n_samples (founder decision).

replace missing fetch_data.py with build, pin, register Both guides told operators and miners to run experiments/fetch_data.py, which does not exist. Operators now get build -> pin -> register; the real commands are doctest-skip:prod because they need a source cache, shards and a live service. A --help doctest keeps the CLI wiring checked. Miners: run-v2 needs no local shards. The service serves each job's samples and sample_proofs objects, and the island verifies every row. Only the v1 run reads data_dir or fetches units through fetch.prefetch, so the guide says that rather than claiming run-v2 uses prefetch. The founder approved three stale lines outside the original block: the operator output line, the determinism checklist entry and the troubleshooting row.

Inspect the public request before co-signing. Use a new output filename for each preparation. Repeat `--origin` for multiple origins; the CLI never creates origins. `escrow-lock --dry-run` prints only the unsigned operation without posting. Its default expiry is the run's current beacon round plus 1000; `--expiry` overrides it. Identical inputs (including reordered origins) reuse the operation ID. Success reports the event hash, current locked units, total required units and server eligibility; funding alone does not guarantee eligibility. The existing `join-v2 --coldkey ...` path remains available. A revoked key is rejected on every authenticated miner route. Only sr25519-signed release manifests are accepted; unsigned tags and downgrades are rejected. During the announce window (at least 600 s) `run --auto-update` stages the new wheel while training continues. At the first round boundary at or after `changeover_at`, it swaps `~/.hypertrain/miner/current` atomically and re-executes the new version, which resumes from the round journal. A miner still on the old version 60 s after changeover refuses new rounds. `update --apply` does the stage and swap by hand. `HYPERTRAIN_UPDATE_ROOT` and `HYPERTRAIN_UPDATE_MANIFEST_URL` override the defaults. diff --git a/src/hypertrain/miner/cli.py b/src/hypertrain/miner/cli.py index f13fb3e..340bf04 100644 --- a/src/hypertrain/miner/cli.py +++ b/src/hypertrain/miner/cli.py @@ -30,6 +30,7 @@

Every profile therefore refused before choosing an offer. Drop the server-side filter and keep eligible() as the only driver check, which was already the trusted one.

The handler raised SystemExit on the first SIGTERM or SIGHUP, so: - a signal that landed during cleanup aborted the DELETE and left the instance billing; - SIGHUP after SIGTERM (only the received signal was ignored) did the same; - a signal during the watchdog's cleanup ended the process with the daemon watchdog thread still before its DELETE; - the handler called api.log, which deadlocks if the main thread holds the journal lock. The handlers were also never restored, leaking into the caller. The handler now does what the watchdog does: record the signal, set cancel and kill the running ssh child (not the rescue once cleanup runs). run() then fails into the existing cleanup("finally"); create() refuses once cancelled; remote_ok is false; handlers are restored when main() returns. Rejected: raising SystemExit and guarding cleanup, which still needs every blocking call to tolerate an exception mid-way.

When that kernel rejects the inputs (fp32, some head dims, or GQA on the RTX 5090 build) the call raised "No available kernel" and training stopped instead of using another kernel. Probe PATHS once per (device, dtype, q heads per kv head, head dim) on tiny zero tensors with grad enabled, cache the first accepting path and log it once. The choice depends only on hardware, torch build and geometry, so ranks and reruns pick the same path. The probe is marked assume_constant_result so HT_COMPILE=1 traces the cached choice. The probe cannot see the real call's layout: a value tensor with stride(-1) != 1 passes the contiguous probe and is then rejected. That call now uses math, logged once per (path, device, dtype). The rejection is not cached, so a later contiguous call still takes the fused path and the path stays a function of the inputs, not of call order. Walking the remaining PATHS was rejected: no production shape hits this, and math is the bitwise oracle.

It exits non-zero when a suite fails, when no tests are collected (pytest exit 5), or when the budget runs out.

PATHS is now flash, then flash on expanded K/V. When neither accepts the inputs (e.g. fp32), or a call's layout is rejected after the probe, the RuntimeError surfaces; such models force HT_ATTN_BACKEND=math. chosen_paths() exposes the paths a process used so run evidence can assert them.

A round only opens on four funded eligible identities with at most one PROBATION member (4 clean trials), so the CLI miner does four trial_export/probe-v2/proof-v2 trials and three peers are graduated in-process by the operator role, labelled "mode": "in-process". Measured 129-132 s over three runs; budget default 300 s. SIGTERM from the budget timeout unwinds main(), so FAIL evidence is written and detached torchrun islands (own session) are reaped by the run's temp dir. MINE_SMOKE_V2_BREAK= points one miner stage at a closed port to prove failure detection. No src/hypertrain change.

Each row moves available -> paid with EscrowV2.pay as a savepoint inside the transaction that stores the epoch answer, so a replayed epoch returns the stored bytes and a failed persist rolls the pay back. A weights_runs_from meta key keeps such a retry off the legacy journal-only path. A stored answer returns before any v2 services are built. Shadow/bootstrap and genesis origins are not paid: they stay collateral for admission locks (founder decision). Transferred or referee-credited units are not paid to the earning hotkey. Rejected: mirroring v2 into the v1 Ledger (two vesting sources of truth).

Miners commit the delta by ref only (miner/core.py run_round) and the master first holds the bytes after relay retrieval, so the grant only worked when an unrelated reference trial had produced identical bytes. The e2e test hid it by putting the delta into the store by hand. Without the original, the grant now accepts a manifest that matches delta_bytes; a lone chunk must hash to delta_hash. A multi-chunk list cannot be checked here: the relay rejects bytes whose concatenation differs from delta_hash at /complete, and relay_receipt_v2 and the rescue recheck size and hash, so no wrong delta is accepted. Rejected: the miner PUTs the delta to the master before the grant; it defeats the relay design (master bandwidth).

NetworkMiner.run_round commits the delta by ref only; the master first stores the bytes in relay_receipt_v2, after the grant. A real miner therefore got 409 "one current signed relay assignment required" unless some other path had written byte-identical content earlier. mine-smoke-v2 passed only by that accident: on the tiny CPU model a peer reference trial (prepare_reference) during graduate-peers often produced the same 1510-byte delta.bin as the miner's round 0. When it did not, run-v2 failed. Deleting that one object before the grant reproduces the failure on every run. With no stored original, the grant now checks what it can: size against commit.delta_bytes (already above) and, for a single-chunk delta, the chunk hash against commit.delta_hash. relay_receipt_v2 still rechecks the retrieved bytes against delta_hash and size before acceptance. When the original is held, the exact chunk-list check is unchanged. Rejected: having the miner PUT the delta to the master before the grant. That adds a full delta upload per round to the master, against the by-ref design in miner/core.py.

That blocks framing, but an honest relay that failed after chunk custody could no longer be rescued or disabled. Without a receipt and the original, upload_grant_v2 cannot tie a multi-chunk list to delta_hash, so a miner can get a grant for arbitrary chunk hashes, upload matching junk, and file custody failure against an honest relay. relay_failure_v2 now records such evidence but defers relay-disabled (disabled: false). relay_fallback_v2 writes it only after the rescued bytes match delta_hash and size; a mismatch stays 422 and the relay stays enabled. The key is still disabled at once with a receipt, a single chunk, or a held original whose bytes prove every chunk hash. Existence of the original alone is not enough: a forged manifest could otherwise disable once the bytes reach the store by another path. Known gap: the timely fallback branch (successor grant before exp_drand) does not rescue, so a deferred failure handled there leaves the key enabled until a later rescue call.

Once the master holds the original it signs a grant for the proven list, but Relay.accept rejected it with "conflicting run/round/miner reservation": nothing on the relay ever clears a reservation, so the honest miner could not upload to its assigned relay. UploadGrant gains an optional `replaces` (digest of the superseded grant), omitted when None so every existing grant digest and signature is unchanged. upload_grant_v2 sets it to the live grant it skips. Relay.accept, after the usual master-signature checks, drops that upload and its nonce when it is the same miner/round/relay and has no receipt; it refuses a receipted or foreign one. A wrong `replaces` removes nothing, so the old conflict check still rejects it. Rejected: a 409 until grant expiry (item 4 fallback), since the additive field needs no wire version change and keeps the miner able to upload within the round.

Inputs are now staged by _stage_once: a new file is written to a mkstemp temp, fsynced and published with os.link, so the final name is complete or absent. An existing file is kept when its bytes are identical and refused with 409 when they differ, never overwritten. The island-job record is put only when absent; an identical stored body is kept and a different one is refused with 409 (the record helper is an INSERT OR REPLACE, so it is not called on repeat). put_large stays as is: object puts are content-addressed and already idempotent. durable_write itself is unchanged (shared with the GPU journal and the audit paths).

Nothing drove several consecutive v2 rounds through the real CLI up to a positive get_weights for the miner hotkey, so readiness could not be shown end to end. The new script reuses the smoke chain (real app on 127.0.0.1, TLS relay, fixture keys, join-v2, escrow-lock, 4 probation trials). Then 4 fixture miners run `hypertrain-miner run-v2` as separate processes for 2 rounds. The operator role audits, aggregates and finalizes. The fixture beacon passes the reward maturity, and GET /internal/v1/get_weights over HTTP must pay miner 0 a positive weight. Two restart probes follow: a rerun after UPLOADED must leave the accepted delta and relay receipts unchanged; a run-v2 SIGKILLed while training, then rerun, must end UPLOADED. On the current base the second probe fails. The rerun gets HTTP 500 because island_job_v2 rewrites job files with an O_EXCL durable_write (src/hypertrain/challenge/store.py:6767). Another session handles the fix; this commit leaves src untouched so the check can be rerun against it. Rejected: extending the od-only _od_production_rounds test, because the od extra is not installed on CI hosts.
