run-stage2.sh: rewrite AGENT_BRIEF to the four-step operator-order journey
(define a paid product + entitlement, integrate the SDK and verify the gate
is BLOCKED, connect BTCPay regtest and have a buyer pay, then the PURCHASED
license unlocks the gate) and add the sandbox-app section the SDK-gating half
needs. Header comment updated to match.
probe.sh: do what the README/brief already claim it does. In addition to the
de-risk payload dump, create both stores (wallet + no-wallet), generate the
on-chain regtest wallet, mint store-scoped tokens with the five documented
connect permissions, and write .live-env for run-stage2.sh / validate-gate.sh
to source. Previously .live-env had to be hand-built and went stale on down -v.
Disposable rig that runs the onboarding-tester agent docs-only against the
buyer-pays journey: a sandbox daemon wired to a Dockerized BTCPay regtest stack,
a scoped key with payment_providers:write, and a regtest buyer-pay helper.
Includes the de-risk probe + findings and an end-to-end gate check
(validate-gate.sh, 10/10). The doc-onboarding loop converged completed-clean;
see stage2/STAGE2-RESULT.md. Scratch (.live-env, probe-out/) is gitignored.
