exits. It does **not** edit `wrangler.jsonc` for you — you paste each id
into `env.production` by hand.

1. `wrangler d1 create adrive-production`
→ paste the printed id into `env.production.d1_databases[0].database_id`.
1. Create the PlanetScale Postgres database and a Hyperdrive config for it
(`wrangler hyperdrive create adrive-production --connection-string=... --caching-disabled`)
→ paste the printed id into `env.production.hyperdrive[0].id`. Keep the
connection string; `bun release` needs it as `DATABASE_URL`.
2. `wrangler r2 bucket create adrive-production`
(no id to paste — the bucket is bound by name.)
3. `wrangler kv namespace create AUTH_GUARD --env production`
→ paste the printed id into `env.production.kv_namespaces[0].id`.
4. Create the Vectorize index and its three metadata indexes:

```
wrangler vectorize create adrive-production --dimensions=384 --metric=cosine
wrangler vectorize create-metadata-index adrive-production --property-name=deleted --type=boolean
wrangler vectorize create-metadata-index adrive-production --property-name=kind --type=string
wrangler vectorize create-metadata-index adrive-production --property-name=visibility --type=string
```

**Gotcha (expected, safe):** metadata-index creation is async — each
command returns "enqueued", and `wrangler vectorize list-metadata-index
adrive-production` shows them appearing one at a time over a minute or
two. That is propagation lag, not a failure. It is harmless because no
vectors are written until after the first deploy, so you don't need to
wait for all three before continuing.

**Workers AI needs no provisioning** — it activates from the `ai`
binding already declared in `wrangler.jsonc` `env.production`.
4. Semantic search needs no extra provisioning. Embeddings come from
the Workers AI `ai` binding already declared in `wrangler.jsonc`
`env.production`, and the vectors are stored in Postgres
(`file_chunks.embedding`, pgvector), which the `HYPERDRIVE` binding
already reaches.

Note: `env.production` sets `SEMANTIC_SEARCH=required` (not `auto`), so a
missing `AI` or `VECTORIZE` binding fails the deploy **loudly** instead
of silently degrading to keyword search. That is intended — if the
Vectorize/AI setup above is incomplete, the deploy in step 5 will stop.

P2 Remove obsolete D1 check

The mandatory binding list still requires DB (D1), but the production Worker now declares HYPERDRIVE and has no D1 binding. A valid Postgres deployment therefore fails this verification check solely because DB is absent. This is non-blocking for the deployed Worker, but it prevents a passing deployment report; remove DB (D1) from the expected bindings.

Artifacts

Postgres binding-check fixture

  • This fixture evaluates the documented binding requirements against a D1 control and the production Postgres Worker configuration.

Postgres binding-check output

  • This output shows the D1 control passes and the current Worker fails only because the obsolete DB/D1 binding is absent.

Documentation still references D1 after the binding removal. This PR removes the D1 binding and moves canonical storage to Postgres, but two documents still describe D1 as a required resource.

  • .agents/skills/verify-deployment/SKILL.md#L60-L61: remove DB (D1) from the mandatory binding list so the acceptance gate can PASS against a deployment that declares only BUCKET, AUTH_GUARD, HYPERDRIVE, and AI.

### Optional semantic search

Keyword, typo-tolerant, tag, and extracted-text search work without AI bindings.
`SEMANTIC_SEARCH` defaults to `auto`: both `AI` and `VECTORIZE` must be present
before the semantic layer activates. Set it to `off` to force the null-object
layer, or `required` to make a missing binding a startup error.
