About · 05Tokyo · Incoming Cambridge HSPS

Coordination is the through-line.

I am Chak Hang (Howard) Chan. I build in Tokyo and I start Human, Social, and Political Sciences at Peterhouse, Cambridge, in October 2026. What follows is the record: fifteen claims about work done between May and September 2026 that survive a reference check, each with its date, and the roles behind them. Nothing on this page is written without a source line behind it.

The method is reading an institution from what a rule forces it to disclose. It was applied to filings, to a live catalogue, and to a production platform, and the claims below are what that produced.

05.1The record, fifteen claims
  1. 01Built a per-investor model that forecasts which position a large institution buys next, measured out of sample on 124,731 held-out US quarterly-disclosure rows across 49 managers and 35 quarters: AUC 0.676, 95 percent interval 0.656 to 0.700, against a 12.5 percent base rate. Measured 16 September 2026.
  2. 02Collected and normalised ownership-disclosure filings from 29 national registers, 1,717,803 filings across 26 panels, resolving filer identity across jurisdictions with no shared identifier; the modelled subset is 68,180 large-shareholding crossing notices from 5 registers. Recomputed 17 September 2026.
  3. 03Replicated the model on the Japanese register at 0.713 (interval 0.610 to 0.797) against a shuffled-label control of 0.503. Japan is the only one of the five registers that clears the quotability bars, and those bars were fixed after the results were seen. No date in the record.
  4. 04Published forecasts with a cryptographic timestamp before the outcome and graded them in public under a rule written in advance: 85 calls stamped, 32 matured, 3 hit, Japan 3 of 14 against 0.5 expected. 11 September 2026.
  5. 05Ran a registered hypothesis programme with an index of verdicts: 77 confirmed, 45 refuted, 13 underpowered as of 8 September 2026. Two results survived multiple-testing correction, a negative 2.02 percent 63-day drift after a class of US ownership amendment and a positive 5.03 percent 21-day move on activist-intent purchases.
  6. 06Found and documented that a live storefront's quote-request control had never rendered on its product pages, so the quote system had never been usable by a customer. August 2026.
  7. 07Recovered 1,737 product records deleted by a data bug on the same day they were lost, partly from surviving image archives. 13 August 2026.
  8. 08Rebuilt and shipped a 3,499-photo, 6,675-attachment media restamp across a live catalogue, verified at a public URL. 15 September 2026.
  9. 09Published new category pages, retitled listings and resubmitted the sitemap on a live commercial site, with the titles approved by the business owner. 16 to 17 September 2026.
  10. 10Shipped a security change to a production tutoring platform: row-level access control across 41 files, tenant separation, a demo-mode fix and a fail-closed meeting webhook, verified live. August 2026.
  11. 11Ran direct outreach at hand-sent scale: between 35 and 99 tutors contacted with several replies (25 August 2026), a further batch of 75 (11 September), and 29 schools emailed by hand (15 September). No placement followed.
  12. 12Verified background-check certificates for a small group of tutors and wrote the policy documents that govern them. 28 August 2026.
  13. 13Handed a working environment to a cofounder: publishing access to both company domains, company inbox and repository access, and a locale handoff. July to 12 September 2026.
  14. 14Held a research meeting with a corporate-governance professional in Japan and supplied a filings dataset afterwards; a professor answered a research email the same week in August. 3 September 2026.
  15. 15Submitted an internship application (18 August 2026) and an accelerator progress report (12 August 2026, unconfirmed at the reading).

Each number is the claim's position in section 5 of the honest record dated 17 September 2026. The same file renders the CV. Nothing from section 6 of that record, the claims that would not survive, appears here.
