 - **`casa-bonavita` has no home yet.** The day's best travel hero, and deliberately not forced into this bundle: it is a destination, and this bundle is explicitly about everything *except* the destination. Its natural neighbours are the restored-hotel finds sitting unbundled since 06-21 (cori-hornbaek-hotel, four-seasons-cartagena, villa-argentina-dubrovnik, pocketbook-hudson, hotel-corazon-mallorca) — a strong, entirely hero-bearing cluster on adaptive reuse, but `2026-07-25-places-that-dont-just-sit-there` shipped two days ago and `2026-07-20-outlived-their-first-purpose` covers buildings given a new job. Worth writing once a run or two has put distance between them.
 
 Uncovered from today's shortlist (8): golf-course-browser, sunflowers-logic-puzzle, semisim-transistor-animations, marbles-on-piano-strings, plus the four held-back software finds above. None was padded in to raise the count.

+## 2026-07-27 — reviews: birc, cayin-cp6, marbles-on-piano-strings (+ 1 rejected, 1 held)
+
+Three graduations from today's shortlist. The run's top-ranked review candidate was **rejected on fact-check** — see below; it is the most consequential decision of this stage.
+
+### review: birc
+
+Graduated from find captured on 2026-07-27, source: Daring Fireball — Linked List.
+Hero: the first Mac App Store screenshot at 1600×1000 (requested via the mzstatic thumb size suffix rather than the default 800×500). The developer's own site publishes only an app icon, so there was no richer first-party asset; the App Store shot is a real in-app window — Libera in the sidebar, #MacOSX selected, 357-name member list — with no marketing text.
+Category: messaging (existing — joins the one other review there).
+Fact-check: **find held up and was slightly expanded.** Confirmed against birc.app's own feature pages and the iTunes lookup API: free, version 1.1.4, developer Fredrik Blank, **macOS 14.6 or later** (the find did not state a requirement). Confirmed IRCv3 coverage, CHATHISTORY replay, CertFP/SASL, SOCKS5 and HTTP-CONNECT with remote DNS, ZNC/soju bouncer support, and DCC with passive mode, resume and automatic port mapping.
+Honest limitation surfaced (per the charter): **it is not open source.** The developer's own /about text says he may open it later but, as a sole developer treating it as a side project, does not want pull requests he cannot service. Stated in the review because anyone planning to lean on the sandboxed JavaScript automation API should know the codebase is one person's.
+Amazon: n-a (software).
+
+### review: cayin-cp6
+
+Graduated from find captured on 2026-07-27, source: Gear Patrol.
+Hero: a second Cayin studio shot (1800×1800, three-quarter view showing the copper Timbre Menu key and both headphone jacks), deliberately different from the 2048×2048 front view left on the find so the two pages do not show the same image twice. Both from Bloom Audio's CDN — clean product photography with no overlay text; Cayin's own site serves a distributor logo as its og:image.
+Category: music (existing).
+Fact-check: **one real correction.** The find as drafted from Gear Patrol said the switch moves between "tube and solid-state." Cayin's own product page gives **three** voicings — Classic Tube, Modern Tube and Solid-State — and adds that the selection applies to the headphone output, line out *and* Bluetooth transmission, not only the analogue path. The find was corrected before publishing. Also confirmed: two Raytheon JAN6418 pentodes on a silicone damping suspension, a discrete symmetrical four-channel headphone amp switchable Class-A/Class-AB across 8–600Ω, LDAC / aptX Adaptive / aptX HD in both directions, and lossless one-button CD ripping to USB storage.
+Prices reconciled across sources rather than taken from one: ~$699 through US dealers, €998 in Europe, ¥3,498 mainland. The review gives the two Western figures and says distribution runs through specialist dealers.
+Honest limitation surfaced: ~7.5 hours of battery, varying substantially by mode — tubes cost power.
+Amazon: n-a. Checked and omitted: an audiophile CD player at this price sells through specialist hi-fi retailers, and no confident first-party Amazon listing exists. A marketplace listing would fail the same-maker-same-model test.
+
+### review: marbles-on-piano-strings
+
+Graduated from find captured on 2026-07-27, source: The Awesomer.
+Hero: the video's own YouTube thumbnail at 1280×720 — checked frame by eye before use and it is **text-free**, unlike the title-card thumbnails this creator often ships (and unlike the frozen-polygon-waves case on 07-25 that forced a same-run hero swap). A concert grand with its string bed under hundreds of coloured marbles, several caught mid-bounce.
+Category: sound (existing — previously held only cities-and-memory-sound-map). Chosen over `music`, which now holds cayin-cp6 from this same run, and over `video`: the subject is the acoustic result, not the medium.
+Fact-check: **one correction, caught before publishing.** The draft named the pianist "Fabrizio Ferrari" — wrong, and invented rather than sourced. Verified via the YouTube oEmbed endpoint (channel *Vinheteiro*, `@Lord_Vinheteiro`, exact title "What Happens If You Put Marbles in a Grand Piano?") and then against Wikipedia and Wikitubia: his name is **Fabrício André Bernard Di Paolo**, a Brazilian pianist and audio engineer born in São Paulo in 1980. Corrected in the review before the file was committed. Recording it because an unverified name attached to a real living person is exactly the error the fact-check stage exists to catch, and it nearly shipped.
+Context added, carefully attributed: the review connects the stunt to John Cage's prepared piano (*Sonatas and Interludes*, 1940s) as the site's own observation — the video does not claim the lineage, and the review does not say it does.
+Amazon: n-a.
+
+### Rejected graduation: discrete6502
+
+**The day's top-ranked review candidate, and it does not graduate.** The find was captured describing a MOS 6502 rebuilt from 4,051 discrete transistors, with 55 LEDs making the register state visible "while it runs." Reading the project's own status section rather than the Show HN framing produced this, in the maker's words: **"Designed and verified — not yet built … No physical board exists yet — nothing here has been proven in copper, only in simulation and geometry."** Boards are being ordered; fabrication and bring-up are the one milestone still open.
+
+That is a review of a design document, not of a thing, and the capture bar excludes not-yet-shipping items. Held as a find; revisit the moment the first board powers up, which the maker frankly notes is "the real test" — the dynamic NMOS logic depends on charge held on long board traces and on a bootstrap effect simulated but never soldered.
+
+**The find was corrected in this same commit**, and this is a factual correction rather than a retroactive rule application (the charter's forward-only rule governs rules, not errors): the body's "make the CPU's state visible while it runs" became explicitly conditional, and the description now states that the design is verified but unbuilt. The correction is small and the find is, if anything, better for it — the project's candour about its own status is part of what makes it good. Worth noting for the operator that the hero is the **PCB layout render**, not a photograph of hardware, because no hardware exists to photograph.
+
+Nothing else about the project failed verification, and much of it is remarkable: 8,421 connections routed by a purpose-built negotiated-congestion router after off-the-shelf autorouters gave up (one managed 700 connections in ten hours), 1,023 pull-up resistors standing in for depletion loads, 778 bidirectional pass gates each doubled into back-to-back pairs, and a logic-equivalence proof run against the visual6502 netlist on every change.
+
+### Held, not rejected: aqua-ui
+
+Ranked third among review candidates and genuinely delightful — Mac OS X Cheetah rebuilt as installable web components, documented inside a working Aqua desktop. Held on maturity, not quality: the GitHub repo was **created 2026-07-26**, one day before capture, carries 4 stars, has no resolved license (`SEE LICENSE IN README.md`, no license file), and both npm packages sit at 0.1.1. Reviewing a two-day-old project at v0.1.1 risks writing 350 words about something that may not exist next month. The find carries it well. Revisit if it is still being pushed in a few weeks.
+
+Verified before holding, so the find's claims stand: both `@aqua-ui/web-components` and `@aqua-ui/react` are really published to npm at 0.1.1, and the documentation desktop works.
