YES
## What kind of change does this PR introduce?
Feature (self-hosted Edge Functions)
## What is the current behavior?
The self-hosted Edge Functions router
(`docker/volumes/functions/main/index.ts`) doesn't tell a function which
slug a request resolved to. As a result, `@supabase/server`'s
`withOAuthProtectedResource` can't derive its canonical resource URL and
falls back to reconstructing it from the request path against the
internal `api-gw` origin, so the advertised OAuth Protected Resource is
/wrong for self-hosted deployments.
## What is the new behavior?
`main/index.ts` now injects `SUPABASE_FUNCTION_SLUG: service_name` per
request (after the `Deno.env.toObject()` snapshot, so nothing in the
container env can shadow it).
Combined with the operator's `SUPABASE_PUBLIC_URL`, the advertised
resource is the correct external
`{SUPABASE_PUBLIC_URL}/functions/v1/{slug}`, not the internal
`http://api-gw:8000`.
Verified on the docker stack: the slug is injected per-function, the
resource origin resolves to `SUPABASE_PUBLIC_URL`, and the `401`
`www-authenticate` carries the right `resource_metadata`.
## Additional context

Companion to `@supabase/server` [PR

injection](https://github.com/supabase/cli/pull/6345)

* **Bug Fixes**
* Edge workers now receive the correct function slug in their runtime
environment, improving per-function request handling.

Updates the self-host Edge Functions template to use `@supabase/server`,
matching the CLI's `supabase functions new` templates (part of SDK-1150,
follows up on #45635 which exposed `SUPABASE_JWKS` to the functions
container). The `hello` example function now wraps its handler in
`withSupabase({ auth: 'none' })` and resolves the package through a
per-function `deno.json` import map, which the runtime auto-discovers,
so no dispatcher changes are needed. The self-hosted functions guide is
updated to match: the create-a-function snippet, a `ctx.supabaseAdmin`
example replacing the manual esm.sh `createClient` wiring, and a note
that `auth: 'user'` requires `SUPABASE_JWKS`. Verified on
`supabase/edge-runtime:v1.74.0` with the compose environment variables:
`curl /functions/v1/hello` returns the same response body as before, so
existing docs and troubleshooting pages stay accurate.
The `docker/.gitignore` change: `volumes/functions/**` ignores
self-hosters' own functions, but it also hid the new `deno.json`, which
must ship with the repo for the `hello` import to resolve. The allowlist
entries follow the existing `main/index.ts` pattern.

## Summary by CodeRabbit
* **New Features**
* Edge Functions now support authenticated invocation with publishable
or secret API keys.
* Function handlers can access authenticated and administrative Supabase
clients through the request context.
* Added automatic environment configuration and JWT verification
support.
* **Documentation**
* Updated the self-hosting guide with the new function setup and
authentication workflow.
* Improved local function examples for supported access patterns and
privileged operations.
* **Tests**
* Updated self-hosted smoke tests to validate publishable-key function
access.
