(23 more lines, ctrl+o to expand) Took 0.2s This same exploration already happened once, so I'm wondering whether to add a third round rather than overwrite, since the existing placements don't yet include the source baseline for comparison that the user wants preserved. The manifest hasn't logged any revisions for these components, so nothing is formally checkpointed yet. I think the right move is to checkpoint the baseline and the existing round drafts into the paper-ds history before creating a new round, rather than risk duplicating work without a record. Since the user wants three placements plus a source comparison, I'll clone the existing option stages into a new round rather than starting fresh — that fills the gap without redoing everything. I'll checkpoint the baseline and option nodes, grab screenshots, and reuse the existing token snapshot since the hash matches. codemode const fid="01M4YDEG7VS396JB65FH21B9D5"; const subs=[["HD-0","r1","Alert r1"],["RV-0","r2","Alert r2 Round 1"],["V0-0","r3","Alert r3 Round 2"]]; const res={}; for(const [id,r] of subs){ const j=await tools.mcp__paper__get_jsx({fileId:fid,nodeId:id,format:"inline-styles"}); res[r]={jsx:j.content.map(c=>c.text).slice(1).join("\n")}; const s=await tools.mcp__paper__get_screenshot({fileId:fid,nodeId:id,scale:1}); const img=s.content.find(c=>c.type==="image"); res[r].png=img.data; res[r].mime=img.mimeType; ...

Actually, I realize option 01 from Round 1 already represents the native/source placement at the narrower stage width, so recreating a separate "source" column would just be redundant. Given that, Round 1 already satisfies the request fully, so I should stop here, verify my earlier checkpoint and screenshot are consistent, and report back rather than redrawing anything. The three Alert action placements are already on the canvas, so I didn't draw a duplicate sheet. They're in Alert r2 Round 1 (RV-0) on the "Alert exploration" page. Every option uses the same payment error ("Unable to process your payment. / Please verify your billing information and try again.") and the same Retry button, in light and dark. 1. Native action: Retry stays in the source top-right slot. This is the source placement, so it is your comparison baseline. It gives up message width. 2. Below description: Retry follows the message. It gives up a little height. 3. Separated footer: a rule divides the message from Retry. It gives up density and simplicity. The page also has Alert r3 Round 2 (V0-0), a refinement of option 2 with a 12px gap above Retry. The untouched source Alert is Alert r1 (HD-0) on the Alert page. None of this was recorded in paper-ds.json, so I checkpointed it before touching anything: - Saved files: artwork JSX and a light+dark screenshot for r1, r2 and r3, under paper-ds/history/alert/rN/. - Manifest: r1 is recorded as the baseline and still the current revision. r2 and r3 are recorded as drafts, both marked as found on the canvas and checkpointed late. Nothing is approved or implemented. - Tokens: they still match the existing snapshot (hash ad7a869b), so I reused tokens-r1.json. I didn't change anything on the canvas. Which of these do you want? - New round: a fresh set of three placements as a new sheet (r4), leaving the existing rounds untouched. - Long-message check: a stress test of the existing three with a longer error, which is where the native slot is most likely to break. - Refine a survivor: if one of the three already looks right, I'll iterate on that one. Use paper-ds-iterate on option 2, Retry below the description, in both themes. Read the current nodes and any edits on them first.

Now I'm figuring out the columns and rows: current vs. long message, light vs. dark, then an in-context row showing the card layout at realistic width with both themes side by side. I'm drafting the actual long error copy about a declined card charge, and planning to reuse real Button component clones for light and dark to keep token styling intact, then build the artboard with proper spacing variables and duplicate the template sheet onto the new page before moving it into place. Rather than fuss with cross-page cloning, I decide it's simpler to hand-build the header manually using the same tokens as the template. I'm sketching out the artboard dimensions, padding, and gap values, writing a small theme/variant alert builder, sizing the stages so the longer message wraps cleanly, and preparing the section labels and trade-off text before writing it all out. codemode const fid="01M4YDEG7VS396JB65FH21B9D5"; const r=await tools.mcp__paper__create_artboard({fileId:fid,name:"Alert r4 Round 3",pageId:"p-4-0",styles:{width:"1376px",height:"fit-content",display:"flex",flexDirection:"column ",left:"2928px",top:"0px",gap:"var(--spacing-6)",padding:"var(--spacing-8)",backgroundColor:"var(- -color-background)"}}); const txt=r.content.map(c=>c.text).join("\n"); return txt.slice(0,800); ✓ mcp__paper__create_artboard {"fileId":"01M4YDEG7VS396JB65FH21B9D5","name":"Alert r4 Round 3","pageId":"p-... 18ms { "file": { "id": "01M4YDEG7VS396JB65FH21B9D5", "name": "paper-skills recording scratch (do not share)" }, ...

I didn't change the design, because nothing broke. Start state: no one had edited the canvas. Nothing was selected, and the Round 1 and Round 2 nodes matched my earlier checkpoints exactly. I took option 2 to mean the latest version, Alert r3 Round 2 (V0-0): Retry below the description with a 12px gap. New sheet: Alert r4 Round 3 (1O9-0) on the "Alert exploration" page. Round 1 and Round 2 are untouched. - Content stress: the Round 2 message sits beside a long one, in light and dark, with a 296px alert. Only the description changes. The long one is 177 characters ("Your card issuer declined the $48.00 charge. Check that the card number, expiry date and billing address match your statement…"). I wrote this copy for the test because the source has no long payment error. - In context: the long error sits under the header of the real Billing details Card, at the card's content width, in both themes. - Same Button: Retry is a clone of the source outline-xs Button from the Alert page (I8-0 light, JA-0 dark), not a redraw. What the test showed: - Wrapping: the long description wraps to five lines at 296px and three lines at card width. Nothing clips, and Retry stays left-aligned with the text. - Height: the long version is about 40px taller than the short one at 296px. That is the same "a little height" cost as before. - Two buttons: inside the card, Retry sits above the card footer's "Update card". Both are visible actions, so a screen like this may need a rule for which one leads. I didn't draw a fix for that. Where the Retry and card parts come from: - The Alert is still redrawn, as in the earlier rounds. - The Card and Button are real instances. Record: r4 is saved as a draft based on r3 in paper-ds.json. The artwork and screenshot are in paper-ds/history/alert/r4/, and it uses the existing token snapshot. Nothing is approved or implemented, and r1 is still the current revision. Next I can try a variant, such as a tighter gap or a full-width Retry on narrow screens. I can also write up r3 for adoption through paper-ds-land if you approve it. Use paper-ds-review on the latest Alert draft.

(54 more lines, ctrl+o to expand) Took 0.1s There's already an unrecorded review display "Review Alert r3" covering the same design, and since r4 only differs in copy length (not the design itself), that existing review should still be adequate — it covers normal, long, 240-char, themes, and billing screen cases. I want to double-check whether the review sheet's alignment with r4's specific content holds before reusing it rather than creating a new one. I should verify the alert design still matches r4's option 02, and dig into real potential issues: pulling the JSX and computed sizes from the review, checking contrast ratios for destructive text tokens against light and dark cards numerically. I also want to inspect layout details — the 240px narrow alert wrapping to two lines, fixed-width stages at 400px, and how the alert sits above the Billing details card alongside the Retry and Update card buttons — to make sure nothing conflicts functionally. Then I'll pull the JSX for comparison. One real issue stands out: the source Alert component reserves 72px of right padding whenever it contains an AlertAction (via a has-data selector), which applies even if the action is repositioned below the description rather than absolutely placed top-right — meaning in a 240px container the usable content width would shrink well below what the Paper review design assumes, since that design has no such reserved padding. This is a genuine code-fidelity mismatch worth flagging. I should also check whether I can actually render the real component to confirm this, and look at the token values for the destructive alert description color in both light and dark modes. codemode const fid="01M4YDEG7VS396JB65FH21B9D5"; const tok=await tools.mcp__paper__get_tokens({fileId:fid}); const txt=tok.content.map(c=>c.text).join(""); const names=["--color-alert-description-destructive","--color-dark-alert-description-destructive","--col or-destructive","--color-dark-destructive","--color-card","--color-dark-card","--color-muted","--c olor-dark-muted","--color-border","--color-dark-border","--color-input","--color-dark-input","--co lor-dark-input-background","--color-background","--color-dark-background","--color-muted-foregroun d","--color-dark-muted-foreground","--spacing-18","--spacing-2-5"]; const o={}; ...

The button border also has low contrast against the white card, failing the 3:1 non-text UI requirement, but again that's inherited from the source Button component. Now I'm moving on to check the review. The dark Retry button style in the review matches source values — it looks redrawn rather than cloned, but functionally equivalent. I'm also questioning whether the billing screen in the review is a real product screen or something invented in a previous round, since the only billing-related thing in code is a "Billing details" section on the Card page — I should grep the source to confirm what screens actually exist before trusting that context. $ cd /private/tmp/pdemo-home/demo/shadcn-app; find src -type f | head -20; cat package.json | head -30; ls node_modules 2>/dev/null | head -3 (timeout 20s) src/globals.css {"name":"paper-shadcn-demo","private":true,"version":"0.0.0"} Took 0.0s Since there's no app or node_modules, I can't actually run code, so I'll record this review in the manifest instead.

I also want to verify the r4 design matches r3's option 02 — it does, since my r4 didn't change anything there — though the review sheet's longer copy differs from r4's. One gap stands out though: neither r4 nor the review sheet tested long copy at a 240px container, which is the worst-case combination the user actually asked about. I think it's worth adding a small supplementary artboard next to XT-0 — cloning the narrow light alert components, setting the description text to the long copy, and laying out a compact "Long content, 240px container" section with two theme stages at 400px each, alert centered at 240px, so this decisive case gets covered. codemode const fid="01M4YDEG7VS396JB65FH21B9D5"; const W=async(id,html)=>{const r=await tools.mcp__paper__write_html({fileId:fid,targetNodeId:id,mode:"insert-children",html});return r.content.map(c=>c.text).join("\n")}; const a=await tools.mcp__paper__create_artboard({fileId:fid,name:"Review Alert r4",pageId:"p-5-0",styles:{width:"880px",height:"fit-content",display:"flex",flexDirection:"column ",left:"960px",top:"0px",gap:"var(--spacing-6)",padding:"var(--spacing-8)",backgroundColor:"var(-- color-background)"}}); const id=a.content.map(c=>c.text).join("").match(/"id": "([^"]+)",\s*"name": "Review Alert r4"/)[1]; ...

It passes the layout checks in both themes, but the light-theme description text fails contrast and the source component can't produce this layout yet. The saved review is a design check, not approval or implementation. Subject: r4 was unchanged since I saved it, and tokens still match (ad7a869b). Its design is the same as r3. There are no Paper comment threads. I reused the existing review sheet Review Alert r3 (XT-0), which already covers normal copy, long copy, 240px and a billing screen. I added Review Alert r4 (1RK-0) on the same page. It shows r4's long copy at 240px, a case the old sheet didn't have. Nothing was drawn as a finding or comment. What passed: - Normal copy: fine in both themes. - Long copy: nothing clips. It wraps to five lines at 296px, three at card width, and seven at 240px. - 240px container: the title wraps to two lines, and Retry stays left-aligned under the text without overflowing. - Billing screen: the alert sits above the Billing details card in both themes, and Retry reads as the alert's action rather than a second card action. Findings: 1. Light description contrast: the description is --color-alert-description-destructive (90% opacity) on the card, about 3.46:1, below the 4.5:1 AA minimum for 14px regular text. The light title is 4.76:1, dark title 6.19:1 and dark description 5.67:1. The fix is to use full destructive for the light description. It comes from the source text-destructive/90 rule, so it isn't specific to option 2. 2. Source can't do this placement yet: in sources/components/alert.tsx, has-data-[slot=alert-action]:pr-18 matches any descendant. Moving AlertAction below the description would still reserve 72px of right padding, so the alert would be 72px narrower than Paper shows. At 240px that leaves about 146px for text, so it would wrap much worse. Option 2 needs a source change, such as an inline placement for the action and no pr-18 reserve. It's an API proposal, not an existing variant. 3. Redrawn Retry in the review sheet: the old XT-0 sheet uses a redrawn Retry. Its values match the source Button (outline, xs, 24px). The new r4 sheet and the round sheets I drew use the Button clone. 4. Light Button border: the outline border is border on white, which is faint. This is inherited from the source Button, not new. Not tested: - Real component render: src/ only has globals.css, with no app or dependencies, so nothing ran in code. The pr-18 finding comes from reading the class string. - Real billing screen: the only billing UI is the Paper-drawn page from the earlier review sheet and the Card from the Card page. - Behavior: keyboard and focus, Retry hover, pressed, loading or disabled states, screen readers and RTL. - Other widths and zoom: only 240px and 296/366/548px. - Other long copy: one error message, with no localized or very long unbroken strings. - Contrast of the Paper renders: I computed it from the token values, not measured from pixels. Record: review 1 is saved against r4 in paper-ds.json, with evidence in paper-ds/history/alert/reviews/r4/. needsReview stays true because the checks are incomplete. I can fix the contrast and draft the source change for finding 2 as an iteration. Nothing goes to code until you approve it. Use paper-ds-manage to report the Alert's status: which revision is canonical, which is the latest draft, and whether anything is implemented. Don't change anything.

Alert status. I only read the manifest, the canvas and git. I changed nothing. Canonical: r1 (baseline, HD-0, "Alert r1" on the Alert page) - It's the source recipe from sources/components/alert.tsx: default and destructive variants, with the native top-right AlertAction. - It's the currentRevision in paper-ds.json. Nothing has been approved to replace it. Latest draft: r4 (1O9-0, "Alert r4 Round 3" on the Alert exploration page) - It keeps option 2 (Retry below the description) as in r3. It adds a long-message test and an in-context test inside the Billing details Card, in both themes, with the real Button clone. - Drafts run r2 → r3 → r4, each based on the one before: - r2 (RV-0): the three placements. - r3 (V0-0): option 2 with a 12px gap. - r4 (1O9-0): the long-message and in-context test. - r2 and r3 were on the canvas before I started. I saved them to history late, and the record says so. Implemented: no - implementedRevision is null, and no revision has an approval or an implementation record. - sources/components/alert.tsx is untouched, and git shows no changes under sources/. - The source can't produce option 2 today. pr-18 is reserved for any AlertAction descendant, so it would need a source change first. Review - Review 1 examined r4. It passed content, 240px and theme checks. - Open findings: light description contrast is 3.46:1, option 2 needs a source change, and the billing screen is Paper-drawn rather than a real product screen. - needsReview is still true, because keyboard behavior, the real render and a real billing screen weren't tested. Drift: none - Tokens still match (ad7a869b, snapshot tokens-r1.json). - r1 through r4 are identical to their saved checkpoints. - No selection, no Paper comment threads, and no user edits since the last round. Housekeeping - The Alert page and the Alert exploration page both have a component version labeled r1, but they're different things: the Alert page holds the source baseline, and the exploration page starts at r2. - The review sheets (XT-0 for r3, 1RK-0 for r4) are recorded only as review evidence, not as artwork revisions. - paper-ds.json, paper-ds/, .agents/ and skills-lock.json are untracked in git. Next step - I'd fix the contrast and draft the source change for option 2 as an iteration (r5). - Once you approve a revision, adopting it goes through paper-ds-land. ──────────────────────────────────────────────────────────────────────────────────────────────────── ──────────────────────────────────────────────────────────────────────────────────────────────────── /private/tmp/pdemo-home/demo/shadcn-app (main) ↑101k ↓32k R2.7M CH97.6% $0.785 10.6%/984k (auto) claude-sonnet-5-5 • medium To resume this session: pi --session 01a13cf2-940c-704e-8bce-152fc0c5d327 ~/demo/shadcn-app $ exit exit
