How Edition № 23 was made

“SK Hynix Put a Deadline on Its Own Buyback. Google Put One on a Warrant.” · Friday, August 21, 2026

No human wrote, edited, or approved this edition. This page is its production record: what the writer agent did, what the independent editor agent checked, what it cost, and how long it took. Assembled from the run's own logs, not written after the fact.

Computed directly from the text and the run, no AI involved. A single quick draft costs a model roughly 1.3 tokens per word. This edition costs far more per published word, because two agents draft, fact-check against live sources, and argue over revisions before a word survives. That gap is the price of getting it right.

The editor's verdict, verbatim

Round 1: AMEND
Verified the bond-buyback fade (Treasury doubling buybacks, stocks giving back gains, Bloomberg's Asian-bonds follow-up), the SK Hynix buyback terms, and Nvidia-Rebellions talks against live search results; core facts and figures check out and voice/craft rules (concrete open, nut graf, no machine-tell phrases, neutral nation framing) pass. Flagged as AMEND solely on source-tier grounds: two load-bearing facts (SK Hynix buyback, Google-Marvell silicon deal) rest on SEO aggregator sources when primary/named-outlet sources are readily confirmed to exist.

Required fixes:

  • The SK Hynix buyback figure (40 trillion won / $28.61B, 24 million shares, Aug 20-Nov 19, >50% FCF floor) is the piece's second headline number, but the draft's source list backs it only with 'AI Weekly: AI News Today,' a generic SEO aggregator. Primary and named-outlet sources are directly available and confirm the same figures (SK Hynix's own newsroom release, plus Bloomberg's 'SK Hynix Inc. unveiled plans to buy back 40 trillion won ($29 billion) of stock... said it will buy back as many as 24 million shares between Aug. 20 and Nov. 19 and cancel them, according to a regulatory filing,' and CNBC/Korea Herald corroboration). Per the source-tier rule, this load-bearing fact must be re-sourced to SK Hynix's filing/newsroom or Bloomberg/CNBC/Korea Herald rather than the aggregator.
  • The Google-Marvell TPU/custom-silicon claim is sourced to 'Tech Startups,' a roundup/aggregator site rather than a primary source or named-outlet reporter. This is a load-bearing claim in the Nvidia-vs-custom-silicon section and should be swapped for original wire or outlet reporting (e.g., Reuters, Bloomberg, CNBC) on the Google-Marvell arrangement if available, per the source-tier rule.

Minor notes (did not block publication):

  • Dollar figure for SK Hynix buyback varies slightly across outlets ($28.6B in the draft vs. $28.7B-$29B in some wire copy) - immaterial rounding, no fix needed.
  • No em-dashes/en-dashes detected in the draft body; no TTS-related dash cleanup required this round.

Round 2: PASS
Verified the SK Hynix buyback figures (40 trillion won / $28.6B, 24 million shares, Aug 20-Nov 19 window, ~69 trillion won net cash, Aug 19 board approval) against Reuters, Bloomberg, CNBC, and SK Hynix's own newsroom release, and the Marvell-Google warrant figures ($12.2B, 58.97 million shares at $206.58, vesting tied to purchases) against Reuters, Quartz, Motley Fool, and TheNextWeb, plus the Morningstar analyst quote — all check out as accurate and multiply corroborated. The 9.2% Tuesday ADR drop is confirmed by a Yahoo Finance/GuruFocus report showing SKHY -9.20% on Aug 18, 2026. Voice passes the craft check: concrete opening (a specific single-session stock drop and board vote), a clear nut graf, varied sentence rhythm, no machine-tell phrases, no dashes, and no negative framing of any nation or leader.

Minor notes (did not block publication):

  • SK Hynix's Tuesday ADR drop is sourced correctly (SKHY -9.20% on Aug 18, 2026), but the piece calls the buyback 'the largest share buyback in South Korean corporate history' when the company's own release and most outlets describe it specifically as the largest treasury share cancellation by a South Korean listed company — a defensible but slightly looser characterization worth tightening.
  • One SK Hynix source (lufkindailynews.com) is a small-paper syndication of a Reuters wire story rather than a direct Reuters/agency link; the same facts are corroborated by Bloomberg and the company's own newsroom release in the source list, so it isn't load-bearing alone, but swapping in a direct Reuters or Yahoo Finance/Reuters link would be cleaner.
  • No em-dashes or en-dashes found in the draft — no TTS fix needed.
The process

Every morning at 6am Eastern, a writer agent searches the live web, chooses the day's through-line, and drafts the edition with every factual claim tied to a source it actually found. A second, independent editor agent then re-searches those claims against live sources. It can pass the edition, or send it back with required fixes; only a pass publishes. A human is the escalation path, never the author. Standards & corrections.
