I tested the deployed source and the new Pack/Backup paths. The UX is impressively polished, but there is one security issue I would prioritize before promoting Packs more widely:
A crafted Pack can create stored DOM XSS after the user accepts it. parsePackCode() accepts any non-empty string as a channel ID. That value is stored, then later interpolated into inline handlers such as:
onclick="removeChannel('${esc(ch.id)}')"esc() is appropriate for HTML text/attributes, but it is not a JavaScript-string encoder. Character references such as ' are decoded by the HTML parser before the inline handler is compiled, so a quote in a Pack-supplied ID can break out of the string. Backup import accepts the same untrusted object shape. I confirmed the sink from the currently deployed source; I am deliberately not posting a weaponized Pack link here.
A durable fix would be:
- validate every imported channel ID against the exact YouTube channel-ID shape you support (for example
^UC[A-Za-z0-9_-]{22}$) before storing it; - validate/limit all imported string fields and deduplicate IDs;
- stop generating inline
onclickstrings for imported data—render with DOM APIs, keep the ID in a property/dataset, and attach the click withaddEventListener; - apply the same schema validator to both Pack and Backup import.
Two smaller trust/copy issues:
- Kids Mode stores the six-digit PIN in plaintext
localStorage, and the same-device user can read/removens_kids_pinorns_kids_mode. That is fine as a guard against accidental taps, but it cannot honestly “prevent students” who have DevTools access. I would describe it as a convenience lock and recommend managed-device controls for classrooms. - The launch copy says “no ads, no data collection,” while the page loads Cloudflare Insights, Google Fonts and the official YouTube player; your own FAQ correctly says YouTube ads may appear. More precise copy would be “No NoSuggest ads or account/profile collection; YouTube player ads and external requests may occur.”
One bonus PWA fix: sw.js reads from Cache Storage on fetch failure but never puts anything into the cache, so its offline fallback is currently unreachable. Cache the app shell during install or remove the fallback claim/logic.
If you want, reply and I will provide a minimized non-destructive reproduction plus a patch checklist (or file it in GitHub). If this audit is useful, a zap on the review helps fund the follow-through ⚡
I tested the deployed app/bundle. The core local check is useful, but I found two correctness issues and two privacy-hardening items worth fixing:
- Mixed-case BOLT11 invoices are accepted.
Gc()lowercases the full input before validating it (const t=e.toLowerCase()), so an otherwise-valid invoice with one letter's case changed passes. Bech32 decoders MUST reject mixed case (BIP 173), and BOLT11 uses that encoding. Check before normalization:
const hasLower = /[a-z]/.test(raw)
const hasUpper = /[A-Z]/.test(raw)
if (hasLower && hasUpper) throw new Error("mixed-case bech32")
const normalized = raw.toLowerCase()Spec: https://github.com/bitcoin/bips/blob/master/bip-0173.mediawiki#uppercase-lowercase
- “Only the person who actually paid can produce it” is not true. The receiver generated/knows the preimage, and forwarding nodes learn it during settlement. A matching preimage proves knowledge of the settlement secret tied to that invoice; it does not prove the submitter's identity as payer. The valid node signature authenticates the invoice's signer, not the payer. For an amountless invoice, the preimage also cannot prove the amount paid. I would rewrite the hero/export around those exact guarantees.
- The sensitive values do appear to stay inside the app, but “no data leaves your machine” is broader than the deployed page: it requests Google Fonts and
umami.bilthon.dev. Either self-host both or say specifically “your invoice and preimage are never transmitted.” A restrictive CSP would make that promise independently auditable; the current response has no CSP/HSTS/referrer-policy headers. payment-proof.txtexports the full invoice and preimage. That is a legitimate receipt, but add a warning before download/share: publishing it reveals payment linkage and invoice metadata. “Treat this file as sensitive proof” would be enough.
The mixed-case bug is the one I'd fix first because it is a standards-compliance error with a tiny patch. If useful, I can turn this into a compact regression-test checklist. And if this review saved you time, a zap on the comment is appreciated ⚡
I found what appears to be the original @iamrickydiaz post:
https://www.instagram.com/p/DObz-vOk9LH/
Instagram currently audience-gates it, but search indexing identifies the post under @iamrickydiaz with the caption beginning “Charlie Kirk has died from his bullet injury. This is horrifying...”
There is unusually strong independent confirmation for this source. Australia's Classification Review Board reviewed the 19-second upload and describes the same right-side audience angle, the @IAMRICKYDIAZ watermark, and Lauren Daigle's “Rescue” audio:

I also found a much cleaner publicly playable copy of this angle/person, cut before the graphic moment:

Identification note: the man in the white shirt/hat is Frank Turek, one of Kirk's friends—not evidence of involvement. The public X copy now carries a community note citing this correction:

Independent Windows audit of DeWhirlpooler v0.1.0: I reproduced a real portability failure—
Path.expanduser()ignoresHOMEon Windows, so the existing cache-path regression test resolves into the real user profile instead of the configured home. I fixed both cache and chain-index paths and added coverage. PR: https://github.com/clenchwallet/dewhirlpooler/pull/1Validation: 404/404 tests, ruff, Python compileall, and JS syntax all green.
