- netlify/functions/ai.mjs: optional Pro enforcement (SASQUATCH_REQUIRE_PRO=1).
Requires a NIP-98 kind-27235 auth header (x-sasquatch-auth) and, unless the
caller is a platform owner, an active Pro pass (x-sasquatch-pro = a
provider-authored zap receipt) verified OFFLINE — signature, user binding,
platform tag, and paid-amount → tier. Off by default.
- src/lib/proAuth.ts: signs the NIP-98 once per session (no Amber popup per
message) and attaches the Pro receipt.
- sasquatchBrain: threads auth headers through the proxy (streaming + non).
- useSasquatchPro: exposes the winning receipt event.
- Verified: 200 with the gate off, 401 with it on (env reset afterwards).
- useSasquatchPro: derive Pro expiry from what was ACTUALLY paid (largest tier
the bolt11 covers, run from the receipt time), instead of trusting the
user-signed `pro-expiry` tag — a 7-day payment could previously self-assert a
year. Provider-authored receipt + amount checks unchanged.
- SasquatchGuide: AI answers are now Pro-only. Free users get the static FAQ,
glossary, trip planner and local relay lookups (all no-cost), plus a nudge to
Pro when a question would otherwise need AI.
- AGENTS.md updated.
Fixes the audit findings:
HIGH-1 (NWC/WebLN auto-pay of unverified invoices): add assertInvoiceAmount and
call it before every programmatic payment in useZaps, useCrewZap, and
SpamFeePayment. A malicious LNURL/Lightning-address server can no longer return
an inflated invoice and drain the wallet — amount is decoded from bolt11 and must
match the intended sats (±1 sat), amountless invoices are rejected.
HIGH-2 (forgeable trust signals):
- useSasquatchPro: Pro is granted ONLY by a zap receipt AUTHORED by the
platform's Lightning provider, embedding a user-signed zap request that tags
the platform, with a real paid amount >= smallest tier. The self-signed
kind:32671 receipt is now advisory only and never grants access (closed the
"self-grant permanent Pro" hole).
- useFeaturedVerification: a listing is 'verified' only when the matching 9735 is
authored by the provider pubkey (not any self-published receipt).
- useCrewGoal: tally only invoice-backed (bolt11) zaps; the forgeable amount tag
is no longer summed, so goal progress can't be inflated with fake receipts.
Bump to 1.2.14.

Adds the Sasquatch Pro supporter pass with strong, forge-resistant
verification bound to the paying user's npub — no backend required.
Verification (useSasquatchPro):
- STRONG: NIP-57 zap receipt (kind 9735). Purchase signs a zap request
tagged pro-tier/pro-expiry; the receipt embeds it, cryptographically
binding payment → identity (unforgeable by the user).
- FALLBACK: self-signed kind-32671 receipt so paying users are never
locked out if the provider emits no zap receipt.
- Platform owners always Pro. Access = max unexpired expiry.
Purchase (usePurchasePro):
- Zap to skatespots@minibits.cash (falls back to plain invoice), pay via
NWC → WebLN → manual QR. Publishes the fallback receipt on success.
Pricing (sasquatchPro.ts): 4 tiers — 7d/2k, 1mo/5k, 3mo/12k (popular),
1yr/36k sats.
UI (SasquatchProDialog): upgrade sheet with tiers, perk list, QR
fallback, "already Pro" state, extend flow.
Gating (SasquatchGuide):
- Personal tools (get_my_*) now require login + Pro; prompt only exposes
them to Pro users; tool switch guards with a pro_required nudge.
- ⚡ Pro badge when active, ⚡ Go Pro button otherwise; local upgrade
nudge for "my/mine" questions from non-Pro users.
Docs: kind 32671 + verification model documented in NIP.md.
