thePR0M3TH3AN adeba151b8 feat: rename to BitGate and close the drop-in gap
Renames the project and makes it as easy to adopt as BitLogin, which was the
stated bar and which it did not previously meet.

Rename (ADR 0005): @nostr-governance/* -> @bitgate/*, governance-* elements ->
bitgate-*, createGovernanceRuntime -> createBitGate. "Governance" reads as DAO
voting to this audience and named a category rather than a product; BitGate
names the benefit and joins the bit- family that BitVid and BitRoad compose
with. Domain types keep their names — the product is BitGate, the subject
matter is still governance. The migration plan is left as written; this ADR
records the change rather than rewriting history.

Drop-in distribution (ADR 0006): adopting BitGate meant supplying a transport,
authoring a policy, and wiring every element in JavaScript. Now:

- createRelayTransport(urls) — WebSocket transport with reconnection, backoff,
  subscription replay, and cross-relay dedupe
- policy presets (social, commerce, admin-only) addressable by name; the engine
  still carries no thresholds of its own
- <bitgate-provider> — configuration in markup, with descendants finding the
  runtime through a bubbling context event rather than DOM walking, which
  breaks across shadow boundaries
- npm run build:widget — a self-contained dist/bitgate.js

That last one came from running it in a browser rather than from a test. Bare
specifiers resolve in Node and vitest but not in a browser, so the widget
source worked everywhere except a plain static page — the one place it exists
to serve. The bundle is not committed: consumers build from reviewed source.

Also found by running it: the provider's ready event fires during element
upgrade, before a page that defines elements after parsing can attach a
listener, so it now exposes `ready` as a promise too.

Four bugs fixed along the way, three found by new tests and one by the browser:
admin state stayed silent when a roster change altered capabilities but no
denials; the relay transport sent every subscription twice on connect; the
commerce preset computed a meaningless visibility verdict at checkout and could
hide a listing from its own seller; <bitgate-status> threw on an unusable
decision.

759 tests; lint, typecheck, and both builds clean.

Commerce proof-of-fit

A marketplace built on nostr-governance, using only the published API.

The point is not to ship marketplace moderation. It is to prove the engine did not accidentally stay video-specific during extraction: if a commerce consumer needs a change to @bitgate/core, the abstraction is wrong.

What it demonstrates

The migration plan lists ten behaviors a commerce consumer should show before 1.0.0. Each is a numbered block in test/proof-of-fit.test.js:

  1. Seller allowlist mode — unlisted sellers are hidden from discovery, but the allowlist is not enforced at checkout
  2. Administrative seller denial — takes the seller's whole catalogue down while leaving them their own dashboard view
  3. Product-address denial — survives the seller republishing under a new event id, and does not touch their other listings
  4. Exact-event denial — affects only the named revision
  5. Trusted scam-report downranking — one report reorders, three block checkout; nothing is hidden on a single signal
  6. Malware checkout denial — one trusted malware report blocks the sale, while three "misleading" reports do not
  7. Moderator capability checks — a listing moderator cannot deny a seller; a seller moderator cannot deny a listing address
  8. Community curator ingestion — curated denials are honored, curator contributions beyond their capability are dropped, and the root cannot be denied through a curated list
  9. Seller-dashboard explanation — the seller sees who reported and why; public surfaces see only counts
  10. No core changes required — four different verdicts for one product from one snapshot, using only exported functions

The shape worth copying

A product answers to three targets — its seller, its exact event, and its address coordinate — and the composed decision is the strictest verdict reaching it. That is what makes "deny the seller" remove every listing without a line of cascade logic in the application.

One product, one snapshot, four surfaces:

Surface Visibility Transaction
public-marketplace restrict deny
product-detail restrict, overridable deny
checkout allow deny
seller-dashboard restrict, with evidence deny

Reviews deliberately answer to their reviewer and their own event — never to the product they review. Otherwise denying a bad product would silence the reviews warning people about it.
