+## 12 — Share a deck or a profile as a QR code (#325) — ✅ PASS (2026-09-20)
+
+Android on `emulator-5554` (Pixel_9, guest) and `emulator-5556` (Pixel_Tablet, signed in as
+`pk:ckm34u…sjx7mo`), iOS on the iPhone 17 simulator (guest), all against staging.
+
+The share buttons used to go straight to the system chooser. They now raise an in-app sheet
+carrying the link as a QR code, and its Share button attaches that code as a PNG.
+
+| Step | Result |
+| --- | --- |
+| Deck detail → `deck_share`, Android phone (dark) | ✅ PASS — sheet shows the deck title, "Scan to open in Loopky", the code and the link |
+| The link when it does not fit | ✅ PASS — elided in the middle (`pubky://rpzu1u4hphjr1fkjxgkcm…s/px6fsekq7i5g/manifest.json`), so both ends stay readable |
+| `share_link_copy` | ✅ PASS — the button reads "Link copied" for two seconds |
+| `share_link_send` | ✅ PASS — chooser opens titled "Sharing image", QR thumbnail beside the named line |
+| The attached PNG | ✅ PASS — pulled from `cache/share/loopky-qr.png` (816², 6 KB) and decoded with zxing: exactly the deck URI, right way up |
+| Friend profile → `friend_profile_share`, guest | ✅ PASS — same sheet with the person's pubky |
+| Own profile → Share, Pixel_Tablet landscape (light, expanded) | ✅ PASS — content capped at `PaneWidth.Focused` and centred, not smeared across the panel |
+| Pixel_Tablet portrait (medium) | ✅ PASS |
+| iOS deck detail → Share | ✅ PASS — sheet fits its content, middle-elided link, "Link copied" on tap |
+| iOS `share_link_send` | ✅ PASS — activity sheet offers Assign to Contact and Print, which only appear when an image is among the items |
+
+### Worth knowing
+
+**The chooser needs `ClipData`, not just `EXTRA_STREAM`.** With the stream extra alone the chooser
+drew no thumbnail, and a receiver that resolves the uri itself would have been refused: the read
+grant rides on the clip. The image is written to `cacheDir/share/`, the one path the new
+`FileProvider` exposes.
+
+**The copy confirmation is on the button, not in a toast.** Android 13 raises its own clipboard
+chip at the bottom of the screen; a toast landed on top of it, so two notices covered the buttons
+that had just moved out of reach.
+
+### Fixed in passing
+
+`DiscoverScreen.swift` did not compile on `main` — `onRetryBrowse` was passed after
+`onGridColumnsChanged`, which `DiscoverView` declares before it. Argument order, nothing else.
