HUMANOIDLEDGER
方法論——引用任何數字之前請先讀。方法論本身就是信任資產：下面寫的是規則，不是摘要。

Methodology

How the Humanoid Ledger is built, what each number measures, and what it cannot tell you. Last updated 2026-11-08.

1. 本站是什麼

一本人形機器人的公開數據帳本：核實過的規格、一條發布年表、官方影片，再加全網已分析的報導——以及由這些報導建起的三本帳（宣稱 vs 實測、評分、問題）。帳本獨立，與所列任何廠商均無隸屬關係。記帳的規矩很簡單：有出處才記，沒核實的寧可寫「未公布」，也不猜一個數字上去。

2. Seed data — verified before entry

The 12 models, 31 release events and 8 official videos were each checked against a vendor page or a trade-press report before entry (seeded 2026-11-06). Every row carries its source link. Prices are vendor-published only: target prices, estimates and unconfirmed reports live in the notes field, never in the price column. Where a figure is unpublished or unverified, the cell says Not stated rather than a guess.

3. Live coverage — sources and the relevance gate

Hacker News (Algolia API), Google News RSS (with Bing News RSS as fallback when Google rate-limits the Worker egress), tech-blog RSS (The Verge, Engadget, Wired, TechCrunch, IEEE Spectrum, The Robot Report, PCMag, Tom’s Guide, 9to5Google, Road to VR, UploadVR), YouTube search pages, and Reddit via Google News. Ingest runs hourly. An item counts for a model only when its headline names the product — vendor + model where the name alone is ambiguous (e.g. “Apollo” only counts with “Apptronik”, “Digit” only with “Agility”, “Atlas” only with “Boston Dynamics”). Items that fail the gate are counted as skipped, not silently dropped.

4. Per-article analysis

Each article is analyzed once by Workers AI (Llama 3.1 8B, max 2048 tokens, JSON only): a 1–3 paragraph summary plus structured extraction — sentiment index, comparison, usage time, recommendation index, per-aspect scores, verifiable claims, issues, and the author’s verdict. The model is instructed never to invent numbers, quotes, durations or facts not present in the evidence; undeterminable fields are null, never invented.

5. Evidence checking (what survives, what is dropped)

Two hard guards run on every analysis before it is stored. First, a compared product is kept only if its name appears in the evidence text (title + snippet + body excerpt); anything else is dropped as model invention, and the compares-with flag is recomputed from the surviving list. Second, a verdict quote is kept only if the exact quote appears in the evidence text; otherwise it is stored as null. Aspect scores are restricted to eight aspects — locomotion, dexterity, battery, payload, autonomy, safety, software, price — each scored −100 to +100 only when the article actually discusses that aspect.

6. The scoring decision — what the three retained fields are, and are not

Decision (2026-11-07): the sentiment index (0–100), the recommendation index (0–100) and the author verdict (buy / wait / skip / mixed, with the author’s own words) are retained in full, in the article cards, in the metrics pages and in the three ledgers. They are kept because they measure the source content and its author — the stance of an article, and the conclusion its author reached — not this site’s judgement of any product. This site issues no rating, no ranking, no recommendation and no prediction of its own: there is no site score anywhere on the ledger, no “best model” list, and no verdict written by us. That is the whole of the exception, and it is the only exception: the general rule for this ledger is the same as the no-scores rule — record what happened, cite the source, add no judgement of our own. The three retained fields are presented with their provenance (which article, analyzed from snippet or full text, with what confidence), with nulls counted and never filled in, so a reader can always see how thin the underlying signal is — for example, the recommendation index is not determined in 308 of 329 analyzed articles, because most coverage is news, not a buying recommendation.

7. 三本帳

宣稱 vs 實測取每篇分析裡的 key_claims；只有模型確實說出實測值時，宣稱才帶實測值列出（截至 2026-11-08，289 條宣稱中有 55 條）。其餘是廠商或來源的宣稱，按原樣記錄——只列出，不作驗證。評分彙總 sentiment_index 與 recommendation_index（分布、計數、僅對非空值取均值）以及作者結論計數。問題按 issues[] 的逐字相同聚類，再按型號分組。某型號在帳裡沒有行，就寫「無記錄」，絕不寫成 0。即時端點：/api/ledger/claims-vs-measured、/api/ledger/scores、/api/ledger/issues（均接受 ?model=<key>）。

8. Limitations — read before quoting a number

9. Corrections

Errors are corrected in the open and logged here, not silently fixed.

10. 歸檔——2026 年 11 月 7 日新增

Five vendor documents are archived as a baseline (Figure 03 announcement, Unitree G1 product page, Boston Dynamics Atlas product page, Agility Digit solutions page, 1X NEO order page), each with a SHA-256 fingerprint of the raw fetch and of the cleaned text, a 6-character seal and a 64-bit SimHash. The baseline is the first archived version; every later check compares the live document against it and records any change in doc_changes (currently 0 rows — 0 changes means nothing has changed since the baseline, not that nothing is watched). Live endpoint: /api/archive; page: /archive/. The Tesla Optimus official page could not be baselined: tesla.com returns 403 to this fetcher. It will be retried with a rendered fetch; until then it is listed on /archive/ as not baselined, not silently omitted.

11. 開放數據——2026 年 11 月 7 日新增

Every dataset behind this site is open JSON with no key. /data/ lists the catalogue with denominators and coverage; /api/open-data returns the same catalogue live, including a row count for every D1 table. Live endpoint: /api/open-data.

12. 二期表——持久表，2026 年 11 月 7 日回填

Four persistent tables were backfilled from the 330 analyzed articles (snapshot 7 Nov 2026, 20:10 EST) and are served live with a ?model= filter. experience_records (55 rows): every key_claim that carries a measured value, classified by metric (locomotion, dexterity, battery, payload, autonomy, safety, software, price, other) — the value is the number as stated in the article, not an independent lab measurement. review_scores (224 rows): one row per analyzed article that carries a sentiment index, a recommendation index or a verdict — metadata only (reviewer = article source, score / 100, date, URL, aspects tested), no quoted opinion text. failure_modes (93 rows): issues clustered per model by identical wording, with mention counts, first/last seen dates and up to 3 source URLs. resale_snapshots (1 row): the G1, with used_price_median NULL — no used-sold market exists for humanoid robots in any reachable public source (see §13). Live endpoints: /api/experience, /api/review-scores, /api/failure-modes, /api/resale.

13. 歷史——過去、現在與未來三段完整，仍為 0 的項及原因

帳本按歷史、現在、未來三段完整記錄，絕不以現在的 0 為起點、只等未來變化再記錄。歷史是基線，沒有基線，未來變化就沒有意義，所以每個維度都要按公開來源與已採文章所能及的範圍回填。2026 年 11 月 7 日回填結果（330 篇已分析文章，2026-11-07 20:10 EST 快照）與已核實的公開記錄：
