Run identical inference jobs on every active node/GPU combo; measure the divergence envelope (TOPLOC exponent/mantissa deltas, logprob-rank spread) under real hardware variance. This must be driven by the tracker (scheduled/dispatched job), not a manual one-off script, so it can be re-run as the fleet's hardware mix changes. Per [ADR-0018 consequences](../../docs/adr/0018-fraud-detection-verification-and-reputation.md): threshold calibration requires an honest-noise corpus across the fleet before production thresholds.

Fleet dispatch exists but is the wrong shape: `_handle_benchmark_hop_penalty` / `_handle_benchmark_results` (`packages/tracker/meshnet_tracker/server.py:2998-3104`, from the old US-030 latency work) targets pinned 1–3-node *routes* and measures latency, not TOPLOC divergence across *every* registered node. +3. Storage is the wrong shape: `record_audit_outcome` (`packages/contracts/meshnet_contracts/__init__.py:416`) persists only `strike_count`/`banned`/`passed` to `registry_events` — no divergence value, no GPU/dtype/hardware-profile column anywhere.

Also fixes a real bug this issue's code-read surfaced: the old code did `bool(_call_toploc(...))`, which is always `True` for the real `toploc` library's non-empty per-chunk `VerificationResult` list regardless of divergence — `tests/test_toploc_audit.py::test_verify_activation_proofs_detailed_aggregates_per_chunk_divergence` exercises this directly. +- [x] Extend the existing fleet-dispatch pattern (`server.py:2998+`) from pinned-route benchmarking to a tracker-scheduled job that hits **every currently registered node** with a fixed prompt/model/seed — `POST /v1/calibration/toploc/run` (admin/validator-gated, same shape as `POST /v1/benchmark/hop-penalty`) in `packages/tracker/meshnet_tracker/server.py`. Dispatches to every node that can solo-serve the full model range (single-hop pinned route, isolating one node's hardware noise from route-composition effects); partial-shard nodes are reported under `skipped_partial_shard_node_ids`, and nodes that don't answer the on-demand TOPLOC commitment fetch are reported per-node under `"skipped": "..."` rather than counted as pass or fail.

A stdlib `urllib.request` GET + `html.parser.HTMLParser`-based table walk is sufficient; no `requests`/`bs4`/Playwright dependency was added, matching this package's existing zero-new-HTTP-dependency convention (`gossip.py`/`raft.py`/`server.py` all use `urllib.request` only). Each row's most stable extraction anchor turned out to be the `` link, not the display text (which duplicates the repo id at two responsive breakpoints and is easy to mis-parse). + +**What shipped:** new `packages/tracker/meshnet_tracker/hf_pricing.py` — pure HTML parser (`parse_hf_pricing_table`), alias matching (`cheapest_matching_quote`, supports both `org/repo` and `org/repo::provider` forms so a human can pin a specific provider's deployment), a pure per-preset computation function (`refresh_preset_price`, never raises), and `HfPricingLog` (SQLite-backed change log, same shape as `billing.py`/`calibration.py`). `TrackerServer` gained an opt-in (`enable_hf_pricing=True` / `--enable-hf-pricing`) daily daemon thread (`_hf_pricing_loop`, same `threading.Event().wait(interval)` shape as `_settlement_loop`) and `GET /v1/pricing/hf/history` (admin/validator-gated, mirrors `/v1/calibration/toploc/results`). `model_presets.json`'s `kimi-k2.7` preset now carries the `hf_aliases`/`hf_verified_match_note` schema fields, left as an empty list pending a human sign-off on a genuinely comparable HF listing (params count + quantization) — per this issue's own "human-verified, not auto-discovered" requirement, an agent should not fabricate that sign-off. This also means the shipped default config demonstrates the required "no alias → static price, unaffected" fallback for a real production preset; the alias→live-fetch→80%→set_price() path is demonstrated end-to-end against an injected fetch backend in `tests/test_hf_pricing_dispatch.py` (the `fetch_html=`/`hf_pricing_fetch_html=` injection point mirrors this codebase's `backend=` convention for anything that would otherwise hit the network in tests). + +**Bug caught and fixed while wiring this in:** `TrackerServer` previously did `dict(DEFAULT_MODEL_PRESETS)` when no explicit `model_presets` was passed — a shallow copy that aliases every preset's inner dict to the shared module-level global. Writing `hf_last_price_per_1k`/`hf_last_updated` in place would have leaked across every other `TrackerServer` instance in the same process (real risk in the test suite, and in any future multi-tracker-in-one-process embedding). Fixed with a `_clone_model_presets()` helper that also shallow-copies each preset dict. + +**Follow-up for a human (not a completion blocker):** populate real `hf_aliases`/`hf_verified_match_note` entries for production presets once someone has confirmed a genuinely comparable HF-listed deployment (params + quantization) — that activates dynamic pricing for that model on the next refresh tick.
