The discount form throws when the code is typed in lowercase, so the Apply button stays on "Applying…". The next commit fixes it; the PR carries the before and after sessions.

Priority: ⬇️ Low Estimated code review effort: 2 (Simple) | ~10 minutes Change: Other Merge Risk: 🟡 Moderate · up to The checkout example ships with the discount fix already applied, so following the README cannot reproduce the "before" bug it is meant to demonstrate. Provide the buggy revision, or a way to serve it, before merging. Two smaller follow-ups remain. The capture script should reject unsafe names before deleting its output directory. The page should stack its columns on narrow screens. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

The submit handler looked the code up as typed, so "save10" found no entry and the destructuring threw before the button was re-enabled. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_018KVkH9Ei4iCN2WvGMAUT1d

Restrict the capture name before deleting the output directory.
name is local command-line input, not an untrusted application value. However, .. or an absolute path makes path.resolve("evidence", name) point outside evidence/, and rm then recursively deletes that path. Reject names that are not single safe directory names before calling rm. This is a minor local-script footgun, not a critical security or data-integrity issue.

Use shell-safe placeholders in the commands.
export CURRENTS_API_KEY=<api key> is not a valid copyable assignment. The <project id> placeholders in both session start commands have the same problem. Use quoted example values or define shell variables before the commands.

Provide a reproducible before state.
The supplied app.js already accepts save10, and node capture.mjs before opens that same page. The “before” command therefore records the fix, not the described frozen Apply button. Provide the buggy revision or a way to serve it, then state when to switch to the fixed revision.

Add a narrow-screen layout.
At a 375px viewport, the 360px summary column, 32px gap, and 64px horizontal padding cannot fit. The checkout extends beyond the screen. Switch to one column at narrow widths and allow the discount input to shrink.

Adds
evidence-sharing/checkout/, an example of recording a browser session as evidence with Currents and sharing it as a link that opens without a login.The example is a one-page checkout with a bug no test covers: a discount code typed in lowercase (
save10) throws in the submit handler, so the Apply button stays on "Applying…" and the total never changes. The first commit adds the page with the bug; the second fixes it. The before and after sessions are in the comments below.capture.mjsdrives the page with Playwright and saves a trace, a video, a screenshot and the accessibility tree. An agent with the Playwright MCP server captures the same files.currents sessionCLI, and the Currents MCP server tools for agents without the CLI.🤖 Generated with Claude Code
