The contract is `defineHttpDrain<TConfig>({ name, label, resolve, encode })`. You only ship two pieces of logic:

1. **`resolve()`** produce a fully-resolved config or `null` to skip. Use `resolveAdapterConfig` for the standard precedence (overrides → `runtimeConfig.evlog.{name}` → `runtimeConfig.{name}` → env vars). List `NUXT_{NAME}_*` before `{NAME}_*` in `ConfigField.env` for silent Nuxt compat; show only `{NAME}_*` in user-facing messages via `formatPublicEnvKeys`.
2. **`encode(events, config)`** a private `encode{Name}Request(events, config): HttpDrainRequest` returning `{ url, headers, body }` for a batch. HTTP transport, identity headers, retries, timeout, and error logging are handled by `defineHttpDrain` (via `httpPost`).

Key rules:

- **Single factory.** Export one `create{Name}Drain(overrides?: Partial<{Name}Config>)`. No dual-API factories: if a service has multiple ingest modes (logs vs events), expose them via a `mode` option (see PostHog).
- **No HTTP code in the adapter.** Never call `fetch` directly. If the service truly needs custom transport (binary envelopes, non-HTTP), use `defineDrain` from `../shared/drain` instead see `fs.ts` and `memory.ts`.
- **Encode parity.** The standalone `sendTo{Name}` / `sendBatchTo{Name}` helpers must reuse the same private `encode{Name}Request()` and go through `sendEncodedDrainRequest(request, { label, source, timeout, retries })`never a separate fetch path. `test/adapters/encode-parity.test.ts` pins this for a subset of adapters; add the new one to it (not every existing adapter is registered there yet that's a gap, not a license to skip).

- **No bespoke config resolution.** Always go through `resolveAdapterConfig`. Deprecated aliases (`token` → `apiKey`) go through `applyDeprecatedAlias`.
- **Exported converters.** If the service needs a specific event shape, export `to{Name}Event()` / `build{Name}Payload()` helpers so they're testable independently.
- **Edge-safe.** Adapters run on Cloudflare Workers: no `Buffer` (use `TextEncoder` + `btoa`, see `loki.ts`), no Node-only APIs. `fs.ts` shows the `isEdgeRuntime()` guard pattern when a runtime genuinely can't be supported.

## Customization Notes

- **Auth style**: Some services use `Authorization: Bearer`, others a custom header (`X-API-Key`, ClickHouse's `X-ClickHouse-User`/`X-ClickHouse-Key`) or HTTP Basic (Loki + Grafana Cloud). Adjust `encode{Name}Request` and prefer headers over query params so credentials never land in server-side query logs.

Adjust `encode{Name}Request`, and prefer headers over query params so credentials never land in server-side query logs.
- **Payload format**: Raw JSON arrays (Axiom), wrapper objects (PostHog `{ api_key, batch }`), protocol structures (OTLP), NDJSON-style bodies (ClickHouse `JSONEachRow`). Adapt the encoder; export intermediate builders (`build{Name}Payload`) when the transformation is non-trivial.
- **Non-HTTP transport**: If the service cannot fit `defineHttpDrain`, use `defineDrain<TConfig>({ name, resolve, send })` see `fs.ts` and `memory.ts`.

- **Deprecated aliases**: When renaming a config field (e.g. `token` → `apiKey`), keep both as `ConfigField` entries and map via `applyDeprecatedAlias(config, { adapter, from, to })` from `../shared/config`. See `axiom.ts` and `better-stack.ts`.
- **Edge safety**: no `Buffer` (use `TextEncoder` + `btoa` for Basic auth see `toBasicCredentials` in `loki.ts`), no Node-only imports. If a runtime genuinely can't be supported, return `null` from `resolve()` with a one-time warning (see `isEdgeRuntime()` in `fs.ts`).

Rules from the test README that apply here:

- Use `mockFetch()` + `getFetchCall` / `getFetchJson` / `getFetchHeaders` from `../helpers/fetch` don't hand-roll fetch spies in adapter tests (a few older files still do; follow the helpers, not them).
- Delete every env var the adapter reads in `afterEach` — leaked env vars make later tests order-dependent.
- Test exported pure helpers (`to{Name}Event`, `build{Name}Payload`, URL resolvers) in their own `describe` blocks but only the ones the adapter actually exports. If the adapter has no converter (service accepts arbitrary JSON), drop the `to{Name}Event` import and its `describe` block entirely.

Make the required test categories source-neutral.

These requirements assume that every enricher reads headers. The documented enricher sources also include ctx.response, ctx.request, process.env, and ctx.event. Require tests against the enricher's actual source. Keep case-insensitive header checks only for header-based enrichers.

Proposed wording

## Architecture Rules

1. **Use the toolkit primitive**: `defineEnricher<T>({ name, field, compute }, options)` from `../shared/enricher` (re-exported as `evlog/toolkit`).
2. **Use the toolkit helpers**: `getHeader()` for case-insensitive header lookup and `normalizeNumber()` for numeric strings — both from `../shared/headers`.
3. **Single event field** each enricher writes one top-level field on `ctx.event` (declared via the `field` option).
4. **Return `undefined` to skip** `compute` returning `undefined` makes the enricher a no-op for that event (no field merge, no errors).
5. **Factory pattern** always wrap `defineEnricher` in a `create{Name}Enricher(options?)` factory and return its result (directly, or through the closure wrapper of rule 7 when pinning top-level fields).
6. **No try/catch** `defineEnricher` already isolates errors (logs as `[evlog/{name}] enrich failed:` and never throws to the pipeline).
7. **No mutation outside `compute`** let `defineEnricher` handle the merge via `mergeEventField`. The one sanctioned exception: pinning top-level fields in addition to the enricher's own field, done by wrapping the `defineEnricher` result in a closure (see `createTraceContextEnricher`, which also sets `event.traceId` / `event.spanId`).
8. **Composition** to combine several enrichers into one callback, use `composeEnrichers` from `../shared/compose` (that's how `createDefaultEnrichers()` is built) instead of a manual loop.
