Pricing: clients are the only party spending real money; nodes only accumulate off-chain credit and get paid in batches (30min dev / 24h later) — a failed distribution leaves funds parked, not lost, so mainnet-vs-devnet mixups are lower-risk than initially assumed. TAI token: do NOT issue/list now — ADR-0002 already locks listing behind $50k volume + 25 nodes/15 wallets plus an unresolved securities-review gate; only a dormant mainnet mint (cheap, ~few $ SOL) for name/branding reservation is in scope, bundled with treasury-key work, not before it. Treasury custody: bare keypair file (current runbook 02) is not acceptable for real funds — plan is **free native SPL multisig** (`spl-token create-multisig`, no protocol fee unlike Squads' 0.5 SOL), 2-of-3 signers, at least one cold/offline, others one-per-hired-VPS-provider to avoid correlated compromise (not yet built — ops task, no issue filed).

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. Research anchor: `.scratch/alpha-hardening/research-verifiable-inference.md` §8 layer 3 — "collect this first — run identical jobs across the current node fleet to measure the honest divergence envelope before setting thresholds." +**Launch context (why this is buildable now, not a research project):** first-launch nodes are hired VPS/VPC hosts under our own direct control (test infrastructure we pay for, not third-party volunteers) — not a long-term topology, but risk-free for calibration purposes since there's no external party to dispute a bad reading. Friends are client-side users of the API in this phase, not node operators. Run the calibration pass against this small, fully-controlled fleet first; hired hosts stay stake-free until it's done, then move to real staking once thresholds derive from their own hardware. + +**Current gap (confirmed 2026-07-06 by code read):** none of the three pieces below exist yet. + +1. `verify_activation_proofs()` (`packages/validator/meshnet_validator/audit.py:94-127`) returns a **plain bool** — no raw TOPLOC divergence/distance value is ever computed or surfaced. Every "done" fraud-detection issue (06–10) currently runs on a guessed threshold baked into that bool, not a calibrated one. +2. 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.

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.

Nodes are unaffected by this loop (per launch design: clients are the only party spending real money; node payouts come from the 90/10 split of whatever price is charged, per ADR-0015/`packages/validator/README.md`).\n\n**Current state (confirmed by code read 2026-07-06):** pricing is 100% static today. `DEFAULT_PRICE_PER_1K_TOKENS = 0.02` (`packages/tracker/meshnet_tracker/billing.py:21`) is the fallback nearly every model hits, since `model_presets.json` currently has no `price_per_1k_tokens` key for any preset. `BillingLedger.set_price(model, price)` (`billing.py:67-69`) is the only write path and already exists — no CLI/admin route calls it yet. No external HTTP/market-data integration exists anywhere in the tracker.\n\n**Data source:** `https://huggingface.co/inference/models` aggregates multiple providers (novita, together, fireworks-ai, deepinfra, etc.) with per-model, per-provider $/1M input and output token pricing; the \"cheapest\" badge already identifies the lowest-cost provider per model on the page itself. It supports a GET query param for filtering, e.g. `?search=GLM`. **No confirmed public JSON API was found** during this session's fetch — the page reads as a rendered table. Owner's suggestion: try a plain `requests` + BeautifulSoup scrape first; if the pricing table turns out to be client-rendered (not present in the initial HTML), that's the fallback signal to escalate to a headless-browser fetch (e.g. Playwright) — confirm which is needed during implementation before building the full pipeline around it. Another data source is acceptable if more convenient/stable, owner is not wedded to this specific page.\n\n## Deliverables\n\n- [x] Live-fetch attempt (requests + BeautifulSoup against the HF page with `?search=`, or an equivalent stable source) as the primary path — confirm during implementation whether the pricing table is present in the raw HTML or requires a headless-browser fetch, and note which in the PR\n- [x] Extend `model_presets.json` per model with: `hf_aliases` (curated list of comparable HF model+provider IDs — **human-verified, not auto-discovered**), `hf_verified_match_note` (free text: params count + quantization confirmation, so a human signs off once per alias that it is a fair comparable before it's used for auto-pricing), `hf_last_price_per_1k` (derived from the $/1M rate), `hf_last_updated` (ISO date)\n- [x] Daily refresh job reusing the tracker's existing daemon-thread pattern (`_settlement_loop`/`_deposit_loop` in `server.py`, `threading.Event().wait(interval)` loop) — for each preset with a non-empty `hf_aliases` list, fetch current pricing for those aliases, compute `0.8 × cheapest matched alias price`, call `set_price()`, and update `hf_last_price_per_1k`/`hf_last_updated`\n- [x] Every price change logged (old price, new price, source alias, timestamp) — needed for dispute auditability if a client questions a charge\n- [x] Fallback behavior: empty/missing `hf_aliases`, fetch failure, or no verified match → silently keep the existing static default price. Never error the pricing path, never zero-price a model\n\n## Acceptance criteria\n\n- [x] At least one model preset has a working end-to-end refresh (alias → live fetch → 80% computed price → `set_price()` called → metadata updated) demonstrated in a test\n- [x] Models without a curated/verified alias continue to use the static default, unaffected by this feature\n- [x] Fetch failures (network error, page structure change, no match found) degrade gracefully — logged, not raised to the request path\n- [x] Price-change log is queryable/inspectable (doesn't need a UI yet — a log line or table row is sufficient for alpha)\n- [x] Note in the runbook/issue on which fetch mechanism (plain HTTP scrape vs. headless browser) was actually required, so the next person doesn't have to rediscover it\n\n## ADR links\n\n- [ADR-0015](../../docs/adr/0015-usdt-custodial-settlement.md) — settlement/pricing this touches (90/10 split, per-model pricing)\n\n## Blocked by\n\nNone — independent of the alpha-hardening trust-boundary work; touches `billing.py`/`server.py` pricing paths only.\n\n## Blocks\n\nNone — ship-soon for launch quality, not a release gate (see status note above).\n", + "acceptanceCriteria": [ + "End-to-end refresh demonstrated for at least one model preset (alias -> live fetch -> 80% computed price -> set_price() -> metadata updated)", + "Models without curated/verified alias continue using static default, unaffected", + "Fetch failures degrade gracefully (logged, not raised to request path)", + "Price-change log is queryable/inspectable (log line or table row sufficient for alpha)", + "Note in issue which fetch mechanism (plain scrape vs headless browser) was actually required", + "Update the source issue file Status header to done when complete", + "Run relevant pytest tests; run the full suite when practical or document why not" + ], + "priority": 23, + "passes": true, + "notes": "Source issue: .scratch/alpha-hardening/issues/23-dynamic-hf-pricing.md.
