 Uncovered after this run (26 finds dated 08-03+): the twelve word/joke/quote items above, plus `boxsquad`, `ododok`, `virtualapple`, `pokeemerald-rp2350`, `catalogue-of-ships` (five hero-less), and nine that do carry heroes — `balmuda-the-brew`, `coodle-cuddling-pillow`, `filerouter`, `golden-age-comics-archive`, `graffiti-moe`, `manhattan-timelapse`, `morningprint`, `statue-of-unity-almaty`, `the-phone-in-your-hand`. Those nine are the strongest raw material the weekly catch will have had in a fortnight and none of them is uncovered for lack of merit — the run hit the 7-cluster ceiling first. `morningprint` is additionally reachable through its own review.
 
 Alcohol-legacy finds excluded from the pool up front, per the charter: `fieldbar-mini-bar`, `do-your-whisky-whiskey-making-kit`. Both remain published and bundled where they already were; neither is counted as awaiting a home.

+## 2026-08-08 — reviews: oshirado, eigendrum, karafuneya-coffee
+
+Three graduations, all from today's own capture — the first run in a week that did not have to clear a backlog of ungraduated candidates first. All three were the run's top three shortlist entries, and all three had a working first-party or scholarly source to check against, which is what decided them over `backscatter-radar-site` and `madrid-model-1830`.

+### oshirado
+
+Graduated from find captured 2026-08-08, source: Atlas Obscura.
+Hero: the find's own image, 6000×4000 — a wall of effigies in layered gold and maroon brocade under clusters of small bells, buried in handwritten prayer cloths. Wikimedia Commons was checked and has exactly one Oshira-sama image, a museum *replica* in Osaka rather than the Denshoen effigies; kept the original.
+Category: places (existing).
+Fact-check: **the find held up on every claim and was substantially thin.** The corrections are all additions:
+- The effigies are not carved dolls. They are foot-long mulberry *sticks* with a face shaped or painted on one end, dressed rather than carved — the visible bulk is decades of accumulated cloth (*osendaku*), added a layer a year. That reframes the photograph: what looks like a thousand statues is a thousand sticks under forty years of fabric.
+- The legend is sourced now: Kunio Yanagita's *Tōno Monogatari*, first published 14 June 1910, built from stories told by Tōno native Sasaki Kizen. One secondary source said 1912 and was wrong.
+- **The sericulture half of the myth was missing entirely from the find**, and it is the half that explains the deity: the daughter returns in a dream and tells her father to feed mulberry leaves to silkworms, which is how Tōno became a silk region and why Oshira-sama governs looms as well as stables. A god of horses *and* silkworms makes no sense until you have that sentence.
+- The curse warning is real and not Atlas Obscura's framing — documented taboos (no meat or egg offerings) and recorded cases of families attributing illness to a neglected effigy. Stated as documented folklore rather than as a spooky flourish.
+- Practical detail added throughout: ~330 yen admission, roughly 9–5 in season, about four hours from Tokyo via shinkansen to Shin-Hanamaki then a local line then a bus, and English signage on site.
+**One thing could not be pinned down**: admission is 320 or 330 yen depending on source. Written as "around 330 yen" rather than picking a side, which is the right call at this precision.
+Amazon: n-a (a museum).

+### eigendrum
+
+Graduated from find captured 2026-08-08, source: Web Curios.
+Hero: `docs/kac-pair.png` from the project's own repo (2010×1410) — deliberately *not* the find's hero, though that one is a genuine screenshot too (md5-identical to the repo's `docs/hero.png`). The Kac pair shot shows the hook-shaped drum mid-ring with the panel reporting all 16 frequencies agreeing to within 1.0e-7 percent, which is the review's centrepiece rather than a generic interface shot.
+Category: play (existing).
+Fact-check: **the find's headline claim about the maths was right and its attribution was wrong.**
+- Confirmed from source: a lattice of right-isosceles triangles snapped and repaired to the drawn boundary, P1 linear finite elements, Dirichlet conditions imposed by dropping boundary rows, generalized eigenproblem Kφ=λMφ solved by block inverse iteration with Rayleigh–Ritz projection, **lowest 16 eigenpairs** (the find gave no number). Draw a circle and the overtones land on Bessel-zero ratios because the physics produces them, not because anyone typed them in.
+- Strike position is real, not decorative: mode amplitude is the projection of the mallet impulse onto the mode shape, so a strike on a nodal line leaves that mode silent — asserted as a tested property in the repo's own test suite.
+- **The correction, and it is the good one.** The find said the toy ships "Mark Kac's two 1966 isospectral drums". Kac posed the question in 1966 and did not answer it; the counterexample came 26 years later from Carolyn Gordon, David Webb and Scott Wolpert in 1992. The project itself gets this right in its UI. The review tells it correctly and says plainly that it is routinely told wrong — which turns a footnote into the best paragraph in the piece.
+- MIT, free, no build step, no backend, nothing uploaded, runs off a bare `index.html`, solver in a Web Worker. Limits stated: ~700ms for a 2,000-unknown mesh, and hairline slivers or self-crossing outlines are refused rather than silently mis-solved. Refusing to answer is a feature worth naming.
+- One nice detail the find missed: formula-drawn outlines are parsed by a hand-written recursive-descent parser rather than `eval`, because a shape can arrive as untrusted input through a shared link.
+Amazon: n-a (a free web page).
+415 words against the 250–450 band.

+
+Graduated from find captured 2026-08-08, source: Atlas Obscura.
+Hero: the find's own image, 6000×4000. Worth recording that the photograph *self-verifies the location* — the signage reads からふね屋珈琲本店, i.e. the Sanjo **honten**, which is how we know the shot is the flagship and not one of the other ten branches.
+Category: places (existing).
+Fact-check: **the find held up exactly, and the cafe's own site supplied everything the find was missing.**
+- 1972 founding confirmed on karafuneya.jp directly (創業1972年).
+- The 150 flavours are **flagship-only**, which neither Atlas Obscura nor the find said. The chain runs eleven locations across Kyoto, Osaka and Okayama, ranging from three varieties to a hundred. Getting this wrong would have sent a reader to the wrong branch, so it is now in the copy.
+- **The giant parfait has a name, a price and a lead time**, none of which were in the find: *Le Rêve* (ル・レーヴ), ¥60,000, 20–25 people, **seven days' advance booking required** — as do the three smaller party parfaits (Jumbo ¥14,000, Bijou ¥30,000, Bouquet ¥20,000, all 8–10 people). "Built to serve 25" is a fun fact; "¥60,000 and call a week ahead" is the thing a reader can act on.
+- The funny parfaits are real, current and priced: Fried Chicken ¥1,380, French Fries ¥1,280, Takoyaki ¥1,280 on real octopus balls. Plus a discrepancy worth keeping rather than smoothing: there is a *second*, separate "Fake Takoyaki Parfait" (¥1,160) that reproduces the look with cream puffs. The review gives it its own sentence.
+- Hours, address and station walk confirmed on the cafe's own shop page. Dutch slow-drip apparatus over a metre tall added from the same source.
+- The 20–25-person figure matched Atlas Obscura exactly, which is worth noting since the two sources disagreed about nothing at all — unusual.
+Amazon: n-a (a cafe).
+376 words against the 250–450 band.

+### Conductor's edits before commit
+
+Two, both mine rather than the copy editor's:
+1. `karafuneya-coffee`'s subtitle came back lowercase ("the Kyoto kissaten…"). Capitalised, to match every other review on the site.
+2. `eigendrum` justified its Kac correction with "because the find that led here got it wrong" — accurate, but it is internal pipeline vocabulary leaking into audience-facing prose. Changed to "because it is routinely told wrong", which makes the same point to a reader who has never heard the word "find" used as a noun. **Recording this as a standing note:** a review may absolutely correct the find it came from, and several of the best ones do, but it should do it in the reader's language, not the pipeline's.
+
+### Considered and not graduated
+
+- **backscatter-radar-site** and **madrid-model-1830** were four and five on the shortlist and both would have made good reviews. Held on source access rather than merit: the radar site has no first-party site of any kind (it is an abandoned military installation), and the Madrid model's museum page is thin enough that the fact-check would have been a second pass over the same Atlas Obscura text. Both stay strong ungraduated candidates.
+- **catalogue-of-ships** was the most tempting hold of the run — it is seventh on the shortlist and its subject is exactly right for a long review. It has no hero and there is no image on the domain to take, and the `the-listening-museum` decision on 08-07 (a title card is not a hero) says a review published with nothing to look at is worse than one that waits. It waits.
+- **the-phone-in-your-hand** remains ungraduated for the second run running, still on the same OG-card hero gap flagged on 08-07. Still the strongest ungraduated candidate on the board by story.
