Why

Goal (Antony): the docs rewrite on campaign/integration, every repo's docs check green against the re-pinned docs action (.github tag v1-campaign, docs action tooling-configs v0.2.17, pin 46816ff). This PR switches this repo's ci-node caller to @v1-campaign and fixes every failure that action reports, so the integration branch stays green.

What changed

• .github/workflows/ci.yml: the ci-node caller @v1 -> @v1-campaign. Other callers stay on @v1.
• docs/tsconfig.json (existing docs project): added module: esnext and moduleResolution: bundler. The root config is CommonJS, which raised TS1378 on top-level await in the examples. The docs project already maps @antelopejs/interface-subscriptions to src/index.ts, and include is unchanged. The plan names nodenext; esnext/bundler is what the merged mongodb and dms docs projects use.
• README.md: the quick-start event handler now imports type Subscription and declares grantOrRevokeAccess(subscription: Subscription): Promise<void>, the application policy the prose already says it stands for (the prose now adds that the declare line only gives it a type). The Compatibility paragraph drops "1.16.0" from "@antelopejs/core 1.16.0 is a development test runner, not a runtime peer." (the one version failure). What stays is true: @antelopejs/core is a devDependency only, and peerDependencies holds only interface-core and interface-payment. The generated block carries those ranges.
• docs/2.subscriptions.md: three loose statements are now complete, checked functions with imports from the public packages: subscribe(accountId, customer, method: PaymentMethod) around CreateSubscription, switchMethod(subscription: Subscription, newMethodId, idempotencyKey) around UpdateSubscriptionPaymentMethod, and cancel(id) around the two CancelSubscription calls. The calls and arguments are unchanged; only the free variables became parameters.
• docs/3.events.md: the event handler imports type SubscriptionEvent and declares alreadyHandled(eventId: string): Promise<boolean> and applyToAccount(event: SubscriptionEvent): Promise<void> (the page already treats them as the application's). The payment-webhook snippet is wrapped in handlePaymentWebhook(request: WebhookRequest) with imports of VerifyWebhook and WebhookRequest from @antelopejs/interface-payment and SUBSCRIPTION_METADATA_KEY; its body is unchanged. Its return was outside any function.
• docs/4.implementing.md:68: 1 fence marked fragment (the 7 remaining-names diagnostics). It is the construct() of an implementing module, whose CreateSubscription, GetSubscription, ListSubscriptions, CancelSubscription, UpdateSubscriptionPaymentMethod, register and unregister are the implementer's own functions defined elsewhere. Proof it is a true excerpt: the block unchanged, with those seven names declared with the interface's own parameter and return types, typechecks against docs/tsconfig.json with ImplementInterface(subscriptions, ...) and no error.
• Fragment markers added: 1. No example deleted. Checked examples go from 9 to 8, which is the one fragment (counts from the Docs: lines of the raw before and of the CI log below).

Proofs

Lever: campaign/tools/docs-measure.sh interface-subscriptions --action 46816ff3bd104560514386e30e73b89478d7989e, copied from its output.

After (committed head bceb643, --dir .): no output, exit 0.

Attention

• Only docs, README, docs tsconfig and the ci-node ref changed. No code, package version, ratchet or suppression change.

Lever after (rerun by me, pin resolved from the caller ref)	exit 0 Docs: 6 files, 17 local links, 1 compatibility tables, 8 checked examples, 0 API pages; 0 failures.
No example dropped	Fence lines in *.md (base head): 32 32. Fragment markers at head: docs/4.implementing.md:64.
Sync	My pnpm exec antelopejs-sync --check on the head: "Guardrails are in sync."
Docs tsconfig	The existing docs/tsconfig.json gains module: esnext and moduleResolution: bundler. Nothing else changes.
Deleted version prose	"@antelopejs/core 1.16.0 is a development test runner" lost its version. devDependencies has @antelopejs/core 1.16.0, and the block carries both peer ranges. The kept sentence "Development uses the same payment-interface semver range" is true, since devDependencies and peerDependencies both say >=0.0.2 <1.0.0.
Edited fences	Each one makes the same calls with the same arguments inside an exported function, with free variables turned into typed parameters, and imports from @antelopejs/interface-subscriptions and @antelopejs/interface-payment. All are checked by CI. grantOrRevokeAccess, alreadyHandled and applyToAccount get declare lines.
Fragment (1 of 1 read)	docs/4.implementing.md:64, construct() of an implementing module, passes the module's own functions to ImplementInterface. The classifier's public-import pass would import the contract's own proxies for those names, which would be wrong code, so this is a true excerpt. Stub check: with each name declared as typeof the matching contract export (and register/unregister as typeof SubscriptionEvents.register/.unregister), the fence typechecks verbatim with 0 errors, and a seeded error is caught.
Examples	Checked examples 9 -> 8, which is the one marker. No fence deleted.
Title, commits, attribution	Conventional title, one commit, no attribution. Body counts match my rerun.

Blocking

None.

Notes

• The body places the fragment at docs/4.implementing.md:68. The marker is on line 64. Cosmetic.
