+
+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`.

+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).

+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.

+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.

+### 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.

 Draw any closed outline and it meshes the interior into thousands of triangles, solves the Laplacian eigenvalue problem, and plays the real vibration modes that shape permits — finite-element math, not a synthesized approximation. Tap different spots on the drawn head and the mix changes, because each mode has its own nodal lines that stay still under your strike. It also ships Mark Kac's two 1966 isospectral drums: different outlines, identical spectrum, indistinguishable by ear.

 Open since 1972 in Kyoto's Sanjo district, Karafuneya Coffee displays all 150 of its parfait and sundae flavors as a wall of plastic food samples. The largest are built to serve 20 to 25 people, piled with whole pineapples and dozens of ice cream cones, and beside the fruit flavors sit "funny" parfaits topped with takoyaki, fried chicken, or French fries.

+
+> Draw any shape and Eigendrum solves the physics rather than faking it — the actual Laplacian eigenvalue problem, played back as the mode mix that outline permits.
+
+It overlays a lattice of right-isosceles triangles on whatever you draw, trims and repairs the mesh to fit the boundary, and solves −∇²u = λu with u = 0 at the edge — the Laplacian eigenvalue problem, by P1 finite elements. A generalized eigenvalue system (stiffness matrix against mass matrix) gives up its lowest 16 eigenpairs by block inverse iteration, and each frequency falls out as the square root of an eigenvalue. Draw a circle and the overtones land on ratios of Bessel-function zeros, because that's what a real circular drum does; nobody typed that in.
+
+Tap the drawing and the timbre shifts with where you hit, and that's physics, not decoration: every mode has its own nodal lines — places on the membrane that never move — and a strike excites a mode in proportion to how far it displaces the surface at that exact point. Land the mallet on a nodal line and the mode stays silent. Solo any of the sixteen modes by pressing its row, or write the outline as a formula — polar r(t) or parametric x(t), y(t) — parsed by a hand-written recursive-descent parser rather than eval'd, since a shape can arrive as untrusted input in a shared link.
+
+The best feature is the isospectral pair, and it's worth telling correctly, because it is routinely told wrong: Mark Kac asked "Can one hear the shape of a drum?" in a 1966 paper — he posed the question, he didn't answer it. The answer, a definite no, came 26 years later from Carolyn Gordon, David Webb and Scott Wolpert, who built two different outlines, a hook and an arrow, both assembled from the same seven right-isosceles triangles, with identical spectra. Eigendrum ships both, labelled "Kac drum I/II" after the question rather than the people who solved it, and doesn't just assert the theorem: solving both live, it reports all 16 frequencies agreeing to within 1.0e-7 percent.
+
+It's free, MIT-licensed, and genuinely serverless — no build step, no backend, nothing uploaded or tracked, and it runs off a bare index.html. The honesty extends to limits: a hairline sliver or a self-crossing outline gets refused outright rather than solved wrong, and a 2,000-unknown mesh takes about 700ms in a background worker; finer meshes for elaborate hand-drawn or equation-drawn shapes take longer.

+
+> A glass case of 150 plastic parfaits greets you at the door of this 1972 Kyoto kissaten — and if you call a week ahead, the kitchen will build you the real one that feeds 25.
+
+Karafuneya Coffee opened in Kyoto's Sanjo district in 1972 as a kissaten, the full-service coffee shop model — a server takes the order and brings it, no tray-carrying — that dominated Japan before self-service chains took over in the 1980s. The company has since grown to eleven locations across Kyoto, Osaka, and Okayama, but the Sanjo flagship, five minutes on foot from Kyoto Shiyakusho-mae Station, is the one that built the reputation: it alone runs roughly 150 parfait and sundae flavors, against three at the chain's smallest branch and 100 at its Osaka Station outpost.
+
+The menu doesn't announce itself with a list. At the entrance sits a glass case stacked with plastic food samples of every parfait on offer, alongside slow-drip Dutch coffee brewed through apparatus over a meter tall.
+
+A menu section labeled, in English, "Funny" carries the toppings that get photographed: a Fried Chicken Parfait (からあげパフェ, ¥1,380), a French Fries Parfait heaped with fries (もりもりポテトフライパフェ, ¥1,280), and a Takoyaki Parfait built on real fried octopus balls (たこ焼きパフェ, ¥1,280). A separate, earlier "Fake Takoyaki Parfait" does the same joke with cream puffs shaped to look like takoyaki, for anyone who wants the bit without the seafood.
+
+Then there's scale. Party-size parfaits run from a ¥14,000 Jumbo Parfait serving 8 to 10 up to Le Reve, a ¥60,000 tower of ice cream, whole pineapple, and dozens of ice cream cones built for 20 to 25 people — matching Atlas Obscura's count exactly. None of the four party sizes are walk-in orders; all require booking at least a week out.
+
+Ordering runs by number off a bilingual menu, so picking a flavor needs no Japanese, though staff and signage mostly do. The Sanjo shop keeps long hours — 9am to 10pm Sunday through Thursday, to 11pm Friday and Saturday — but weekend queues build, and there's no version of showing up and ordering Le Reve on the spot. The wall of plastic samples is free to walk up to any time; the parfait behind it takes a phone call.

+
+> A farmer beheaded his daughter's horse; she rode its severed head into the sky and became a household god of silk and horses. A thousand small effigies of her hang in one room in Tono, each wrapped in a stranger's handwritten wish.
+
+Denshoen is an open-air folk museum outside Tono, in the mountain-ringed interior of Iwate Prefecture, built around a preserved 1750s magariya farmhouse. One pavilion, called Oshirado, holds roughly a thousand effigies of Oshira-sama — a household deity of horses, silkworms, and farming, worshipped mostly in secret across rural Tohoku — hung wall to wall around an old mulberry tree at the room's center.
+
+The effigies aren't carved figures so much as foot-long mulberry sticks, one end shaped or painted into a face — a woman's, or a horse's — dressed rather than carved into a body. Each year a family or shrine adds a fresh layer of cloth, called osendaku, over the last, so what's on the wall today is decades of fabric stacked over a bare stick core. Visitors can buy a cloth for around 100 yen, write a wish on it, and tie it onto whichever effigy catches their eye, which is why the room reads as a wall of color rather than a shelf of statues.
+
+The legend behind it comes from Kunio Yanagita's 1910 *Tono Monogatari*, built from stories told by Tono native Sasaki Kizen. A farmer's daughter fell in love with the family horse and married it in secret. Her father, enraged, killed the horse and cut off its head. The daughter climbed onto the severed head and rose into the sky, becoming a god. She later visited her father in a dream and told him to feed mulberry leaves to silkworms — which is how Tono became a center of sericulture, and why the deity governs looms as much as stables.
+
+The curse warning in circulation isn't Atlas Obscura's invention. Families that keep an Oshira-sama observe specific taboos — no offerings of meat or eggs — and folklore records document households blaming a neglected or improperly tended effigy for a father's eye disease or a run of bad luck. What actually happens at Denshoen's version is harder to pin down: most communities that keep Oshira-sama decline to describe their rituals to outsiders, so this pavilion is the rare public, participatory version of a deity usually kept private.
+
+Getting there costs a day: about four hours from Tokyo by shinkansen to Shin-Hanamaki, then a slow local line to Tono, then a bus or taxi to Denshoen itself. Admission runs around 330 yen, hours are roughly 9 to 5 in season and shorter in winter, and Denshoen provides English signage and pamphlets, so the language barrier is smaller than the trip suggests. What you get for the trouble is one room, thick with a thousand strangers' wishes in a language you probably can't read, wrapped around a legend that ends in a beheading and a loom.
