Onboarding: template backlink, bulk-create endpoint, climate-region scoring

Clients that send users through a multi-task onboarding step no longer loop N POST /api/tasks/ calls and no longer create "orphan" tasks with no reference to the TaskTemplate they came from. Task model - New task_template_id column + GORM FK (migration 000016) - CreateTaskRequest.template_id, TaskResponse.template_id - task_service.CreateTask persists the backlink Bulk endpoint - POST /api/tasks/bulk/ — 1-50 tasks in a single transaction, returns every created row + TotalSummary. Single residence access check, per-entry residence_id is overridden with batch value - task_handler.BulkCreateTasks + task_service.BulkCreateTasks using db.Transaction; task_repo.CreateTx + FindByIDTx helpers Climate-region scoring - templateConditions gains ClimateRegionID; suggestion_service scores residence.PostalCode -> ZipToState -> GetClimateRegionIDByState against the template's conditions JSON (no penalty on mismatch / unknown ZIP) - regionMatchBonus 0.35, totalProfileFields 14 -> 15 - Standalone GET /api/tasks/templates/by-region/ removed; legacy task_tasktemplate_regions many-to-many dropped (migration 000017). Region affinity now lives entirely in the template's conditions JSON Tests - +11 cases across task_service_test, task_handler_test, suggestion_ service_test: template_id persistence, bulk rollback + cap + auth, region match / mismatch / no-ZIP / unknown-ZIP / stacks-with-others Docs - docs/openapi.yaml: /tasks/bulk/ + BulkCreateTasks schemas, template_id on TaskResponse + CreateTaskRequest, /templates/by-region/ removed Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

+# Deploying Right Now
+
+Practical walkthrough for a prod deploy against the current Swarm stack.
+Assumes infrastructure and cloud services already exist — if not, work
+through [`shit_deploy_cant_do.md`](./shit_deploy_cant_do.md) first.
+
+See [`README.md`](./README.md) for the reference docs that back each step.
+
+---
+
+## 0. Pre-flight — check local state
+
+```bash
+cd honeyDueAPI-go
+
+git status                # clean working tree?
+git log -1 --oneline      # deploying this SHA
+
+ls deploy/cluster.env deploy/registry.env deploy/prod.env
+ls deploy/secrets/*.txt deploy/secrets/*.p8
+```
+
+## 1. Reconcile your envs with current defaults
+
+These two values **must** be right — the script does not enforce them:
+
+```bash
+# deploy/cluster.env
+WORKER_REPLICAS=1          # >1 → duplicate cron jobs (Asynq scheduler is a singleton)
+PUSH_LATEST_TAG=false      # keeps prod images SHA-pinned
+SECRET_KEEP_VERSIONS=3     # optional; 3 is the default
+```
+
+Decide storage backend in `deploy/prod.env`:
+
+- **Multi-replica safe (recommended):** set all four of `B2_ENDPOINT`,
+  `B2_KEY_ID`, `B2_APP_KEY`, `B2_BUCKET_NAME`. Uploads go to B2.
+- **Single-node ok:** leave all four empty. Script will warn. In this
+  mode you must also set `API_REPLICAS=1` — otherwise uploads are
+  invisible from 2/3 of requests.
+
+## 2. Dry run
+
+```bash
+DRY_RUN=1 ./.deploy_prod
+```
+
+Confirm in the output:
+- `Storage backend: S3 (...)` OR the `LOCAL VOLUME` warning matches intent
+- `Replicas: api=3, worker=1, admin=1` (or `api=1` if local storage)
+- Image SHA matches `git rev-parse --short HEAD`
+- `Manager:` host is correct
+- `Secret retention: 3 versions`
+
+Fix envs and re-run until the plan looks right. Nothing touches the cluster yet.
+
+## 3. Real deploy
+
+```bash
+./.deploy_prod
+```
+
+Do **not** pass `SKIP_BUILD=1` after code changes — the worker's health
+server and `MigrateWithLock` both require a fresh build.
+
+End-to-end: ~3–8 minutes. The script prints each phase.
+
+## 4. Post-deploy verification
+
+```bash
+# Stack health (replicas X/X = desired)
+ssh <manager> docker stack services honeydue
+
+# API smoke
+curl -fsS https://api.<domain>/api/health/ && echo OK
+
+# Logs via Dozzle (loopback-bound, needs SSH tunnel)
+ssh -p <port> -L 9999:127.0.0.1:9999 <user>@<manager>
+# Then browse http://localhost:9999
+```
+
+What the logs should show on a healthy boot:
+- `api`: exactly one replica logs `Migration advisory lock acquired`,
+  the others log `Migration advisory lock acquired` after waiting, then
+  `released`.
+- `worker`: `Health server listening addr=:6060`, `Starting worker server...`,
+  four `Registered ... job` lines.
+- No `Failed to connect to Redis` / `Failed to connect to database`.
+
+## 5. If it goes wrong
+
+Auto-rollback triggers when `DEPLOY_HEALTHCHECK_URL` fails — every service
+is rolled back to its previous spec, script exits non-zero.
+
+Triage:
+
+```bash
+ssh <manager> docker service logs --tail 200 honeydue_api
+ssh <manager> docker service ps honeydue_api --no-trunc
+```
+
+Manual rollback (if auto didn't catch it):
+
+```bash
+ssh <manager> bash -c '
+  for svc in $(docker stack services honeydue --format "{{.Name}}"); do
+    docker service rollback "$svc"
+  done'
+```
+
+Redeploy a known-good SHA:
+
+```bash
+DEPLOY_TAG=<older-sha> SKIP_BUILD=1 ./.deploy_prod
+# Only valid if that image was previously pushed to the registry.
+```
+
+## 6. Pre-deploy honesty check
+
+Before pulling the trigger:
+
+- [ ] Tested Neon PITR restore (not just "backups exist")?
+- [ ] `WORKER_REPLICAS=1` — otherwise duplicate push notifications next cron tick
+- [ ] Cloudflare-only firewall rule on 80/443 — otherwise origin IP is on the public internet
+- [ ] If storage is LOCAL, `API_REPLICAS=1` too
+- [ ] Last deploy's secrets still valid (rotation hasn't expired any creds)

 ### 6) Dozzle Hardening

- Keep Dozzle private (no public DNS/ingress).
+Dozzle exposes the full Docker log stream with no built-in auth — logs contain
+secrets, tokens, and user data. The stack binds Dozzle to `127.0.0.1` on the
+manager node only (`mode: host`, `host_ip: 127.0.0.1`), so it is **not
+reachable from the public internet or from other Swarm nodes**.
+
+To view logs, open an SSH tunnel from your workstation:
+
+```bash
+ssh -p "${DEPLOY_MANAGER_SSH_PORT}" \
+    -L "${DOZZLE_PORT}:127.0.0.1:${DOZZLE_PORT}" \
+    "${DEPLOY_MANAGER_USER}@${DEPLOY_MANAGER_HOST}"
+# Then browse http://localhost:${DOZZLE_PORT}
+```
+
+Additional hardening if you ever need to expose Dozzle over a network:
+
 - Put auth/SSO in front (Cloudflare Access or equivalent).
- Prefer a Docker socket proxy with restricted read-only scope.
+- Replace the raw `/var/run/docker.sock` mount with a Docker socket proxy
+  limited to read-only log endpoints.
+- Prefer a persistent log aggregator (Loki, Datadog, CloudWatch) for prod —
+  Dozzle is ephemeral and not a substitute for audit trails.

 ### 7) Backup + Restore Readiness

- Postgres PITR path tested in staging.
- Redis persistence enabled and restore path tested.
- Written runbook for restore and secret rotation.
- Named owner for incident response.
+Treat this as a pre-launch checklist. Nothing below is automated by
+`./.deploy_prod`.
+
+- [ ] Postgres PITR path tested in staging (restore a real dump, validate app boots).
+- [x] Redis AOF persistence enabled (`appendonly yes --appendfsync everysec` in stack).
+- [ ] Redis restore path tested (verify AOF replays on a fresh node).
+- [ ] Written runbook for restore + secret rotation (see §4 and `shit_deploy_cant_do.md`).
+- [ ] Named owner for incident response.
+- [ ] Uploads bucket (Backblaze B2) lifecycle / versioning reviewed — deletes are
+      handled by the app, not by retention rules.
+
+### 8) Storage Backend (Uploads)
+
+The stack supports two storage backends. The choice is **runtime-only** — the
+same image runs in both modes, selected by env vars in `prod.env`:
+
+| Mode | When to use | Config |
+|---|---|---|
+| **Local volume** | Dev / single-node prod | Leave all `B2_*` empty. Files land on `/app/uploads` via the named volume. |
+| **S3-compatible** (B2, MinIO) | Multi-replica prod | Set all four of `B2_ENDPOINT`, `B2_KEY_ID`, `B2_APP_KEY`, `B2_BUCKET_NAME`. |
+
+The deploy script enforces **all-or-none** for the B2 vars — a partial config
+fails fast rather than silently falling back to the local volume.
+
+**Why this matters:** Docker Swarm named volumes are **per-node**. With 3 API
+replicas spread across nodes, an upload written on node A is invisible to
+replicas on nodes B and C (the client sees a random 404 two-thirds of the
+time). In multi-replica prod you **must** use S3-compatible storage.
+
+The `uploads:` volume is still declared as a harmless fallback: when B2 is
+configured, nothing writes to it. `./.deploy_prod` prints the selected
+backend at the start of each run.
+
+### 9) Worker Replicas & Scheduler
+
+Keep `WORKER_REPLICAS=1` in `cluster.env` until Asynq `PeriodicTaskManager`
+is wired up. The current `asynq.Scheduler` in `cmd/worker/main.go` has no
+Redis-based leader election, so each replica independently enqueues the
+same cron task — users see duplicate daily digests / onboarding emails.
+
+Asynq workers (task consumers) are already safe to scale horizontally; it's
+only the scheduler singleton that is constrained. Future work: migrate to
+`asynq.NewPeriodicTaskManager(...)` with `PeriodicTaskConfigProvider` so
+multiple scheduler replicas coordinate via Redis.
+
+### 10) Database Migrations
+
+`cmd/api/main.go` runs `database.MigrateWithLock()` on startup, which takes a
+Postgres session-level `pg_advisory_lock` on a dedicated connection before
+calling `AutoMigrate`. This serialises boot-time migrations across all API
+replicas — the first replica migrates, the rest wait, then each sees an
+already-current schema and `AutoMigrate` is a no-op.
+
+The lock is released on connection close, so a crashed replica can't leave
+a stale lock behind.
+
+For very large schema changes, run migrations as a separate pre-deploy
+step (there is no dedicated `cmd/migrate` binary today — this is a future
+improvement).
+
+### 11) Redis Redundancy
+
+Redis runs as a **single replica** with an AOF-persisted named volume. If
+the node running Redis dies, Swarm reschedules the container but the named
+volume is per-node — the new Redis boots **empty**.
+
+Impact:
+- **Cache** (ETag lookups, static data): regenerates on first request.
+- **Asynq queue**: in-flight jobs at the moment of the crash are lost; Asynq
+  retry semantics cover most re-enqueues. Scheduled-but-not-yet-fired cron
+  events are re-triggered on the next cron tick.
+- **Sessions / auth tokens**: not stored in Redis, so unaffected.
+
+This is an accepted limitation today. Options to harden later: Redis
+Sentinel, a managed Redis (Upstash, Dragonfly Cloud), or restoring from the
+AOF on a pinned node.
+
+### 12) Multi-Arch Builds
+
+`./.deploy_prod` builds images for the **host** architecture of the machine
+running the script. If your Swarm nodes are a different arch (e.g. ARM64
+Ampere VMs), use `docker buildx` explicitly:
+
+```bash
+docker buildx create --use
+docker buildx build --platform linux/arm64 --target api -t <image> --push .
+# repeat for worker, admin
+SKIP_BUILD=1 ./.deploy_prod   # then deploy the already-pushed images
+```
+
+The Go stages cross-compile cleanly (`TARGETARCH` is already honoured).
+The Node/admin stages require QEMU emulation (`docker run --privileged --rm
+tonistiigi/binfmt --install all` on the build host) since native deps may
+need to be rebuilt for the target arch.
+
+### 13) Connection Pool & TLS Tuning
+
+Because Postgres is external (Neon/RDS), each replica opens its own pool.
+Sizing matters: total open connections across the cluster must stay under
+the database's configured limit. Defaults in `prod.env.example`:
+
+| Setting | Default | Notes |
+|---|---|---|
+| `DB_SSLMODE` | `require` | Never set to `disable` in prod. For Neon use `require`. |
+| `DB_MAX_OPEN_CONNS` | `25` | Per-replica cap. Worst case: 25 × (API+worker replicas). |
+| `DB_MAX_IDLE_CONNS` | `10` | Keep warm connections ready without exhausting the pool. |
+| `DB_MAX_LIFETIME` | `600s` | Recycle before Neon's idle disconnect (typically 5 min). |
+
+Worked example with default replicas (3 API + 1 worker — see §9 for why
+worker is pinned to 1):
+
+```
+3 × 25 + 1 × 25 = 100 peak open connections
+```
+
+That lands exactly on Neon's free-tier ceiling (100 concurrent connections),
+which is risky with even one transient spike. For Neon free tier drop
+`DB_MAX_OPEN_CONNS=15` (→ 60 peak). Paid tiers (Neon Scale, 1000+
+connections) can keep the default or raise it.
+
+Operational checklist:
+
+- Confirm Neon IP allowlist includes every Swarm node IP.
+- After changing pool sizes, redeploy and watch `pg_stat_activity` /
+  Neon metrics for saturation.
+- Keep `DB_MAX_LIFETIME` ≤ Neon idle timeout to avoid "terminating
+  connection due to administrator command" errors in the API logs.
+- For read-heavy workloads, consider a Neon read replica and split
+  query traffic at the application layer.

 ## Useful Flags

 Environment flags:

- `SKIP_BUILD=1 ./.deploy_prod` to deploy already-pushed images.
- `SKIP_HEALTHCHECK=1 ./.deploy_prod` to skip final URL check.
- `DEPLOY_TAG=<tag> ./.deploy_prod` to deploy a specific image tag.
+- `DRY_RUN=1 ./.deploy_prod` — validate config and print the deploy plan
+  without building, pushing, or touching the cluster. Use this before every
+  production deploy to review images, replicas, and secret names.
+- `SKIP_BUILD=1 ./.deploy_prod` — deploy already-pushed images.
+- `SKIP_HEALTHCHECK=1 ./.deploy_prod` — skip final URL check.
+- `DEPLOY_TAG=<tag> ./.deploy_prod` — deploy a specific image tag.
+- `PUSH_LATEST_TAG=true ./.deploy_prod` — also push `:latest` to the registry
+  (default is `false` so prod pins to the SHA tag and stays reproducible).
+- `SECRET_KEEP_VERSIONS=<n> ./.deploy_prod` — how many versions of each
+  Swarm secret to retain after deploy (default: 3). Older unused versions
+  are pruned automatically once the stack converges.
+
+## Secret Versioning & Pruning
+
+Each deploy creates a fresh set of Swarm secrets named
+`<stack>_<secret>_<deploy_id>` (for example
+`honeydue_secret_key_abc1234_20260413120000`). The stack file references the
+current names via `${POSTGRES_PASSWORD_SECRET}` etc., so rolling updates never
+reuse a secret that a running task still holds open.
+
+After the new stack converges, `./.deploy_prod` SSHes to the manager and
+prunes old versions per base name, keeping the most recent
+`SECRET_KEEP_VERSIONS` (default 3). Anything still referenced by a running
+task is left alone (Docker refuses to delete in-use secrets) and will be
+pruned on the next deploy.

+# Shit `./.deploy_prod` Can't Do
+
+Everything listed here is **manual**. The deploy script orchestrates builds,
+secrets, and the stack — it does not provision infrastructure, touch DNS,
+configure Cloudflare, or rotate external credentials. Work through this list
+once before your first prod deploy, then revisit after every cloud-side
+change.
+
+See [`README.md`](./README.md) for the security checklist that complements
+this file.
+
+---
+
+## One-Time: Infrastructure
+
+### Swarm Cluster
+
+- [ ] Provision manager + worker VMs (Hetzner, DO, etc.).
+- [ ] `docker swarm init --advertise-addr <manager-private-ip>` on manager #1.
+- [ ] `docker swarm join-token {manager,worker}` → join additional nodes.
+- [ ] `docker node ls` to verify — all nodes `Ready` and `Active`.
+- [ ] Label nodes if you want placement constraints beyond the defaults.
+
+### Node Hardening (every node)
+
+- [ ] SSH: non-default port, key-only auth, no root login — see README §2.
+- [ ] Firewall: allow 22 (or 2222), 80, 443 from CF IPs only; 2377/tcp,
+      7946/tcp+udp, 4789/udp Swarm-nodes only; block the rest — see README §1.
+- [ ] Install unattended-upgrades (or equivalent) for security patches.
+- [ ] Disable password auth in `/etc/ssh/sshd_config`.
+- [ ] Create the `deploy` user (`AllowUsers deploy` in sshd_config).
+
+### DNS + Cloudflare
+
+- [ ] Add A records for `api.<domain>`, `admin.<domain>` pointing to the LB
+      or manager IPs. Keep them **proxied** (orange cloud).
+- [ ] Create a Cloudflare tunnel or enable "Authenticated Origin Pulls" if
+      you want to lock the origin to CF only.
+- [ ] Firewall rule on the nodes: only accept 80/443 from Cloudflare IP ranges
+      (<https://www.cloudflare.com/ips/>).
+- [ ] Configure CF Access (or equivalent SSO) in front of admin panel if
+      exposing it publicly.
+
+---
+
+## One-Time: External Services
+
+### Postgres (Neon)
+
+- [ ] Create project + database (`honeydue`).
+- [ ] Create a dedicated DB user with least privilege — not the project owner.
+- [ ] Enable IP allowlist, add every Swarm node's egress IP.
+- [ ] Verify `DB_SSLMODE=require` works end-to-end.
+- [ ] Turn on PITR (paid tier) or schedule automated `pg_dump` backups.
+- [ ] Do one restore drill — boot a staging stack from a real backup. If you
+      haven't done this, you do not have backups.
+
+### Redis
+
+- Redis runs **inside** the stack on a named volume. No external setup
+  needed today. See README §11 — this is an accepted SPOF.
+- [ ] If you move Redis external (Upstash, Dragonfly Cloud): update
+      `REDIS_URL` in `prod.env`, remove the `redis` service + volume from
+      the stack.
+
+### Backblaze B2 (or MinIO)
+
+Skip this section if you're running a single-node prod and are OK with
+uploads on a local volume. Required for multi-replica prod — see README §8.
+
+- [ ] Create B2 account + bucket (private).
+- [ ] Create a **scoped** application key bound to that single bucket —
+      not the master key.
+- [ ] Set lifecycle rules: keep only the current version of each file,
+      or whatever matches your policy.
+- [ ] Populate `B2_ENDPOINT`, `B2_KEY_ID`, `B2_APP_KEY`, `B2_BUCKET_NAME`
+      in `deploy/prod.env`. Optionally set `B2_USE_SSL` and `B2_REGION`.
+- [ ] Verify uploads round-trip across replicas after the first deploy
+      (upload a file via client A → fetch via client B in a different session).
+
+### APNS (Apple Push)
+
+- [ ] Create an APNS auth key (`.p8`) in the Apple Developer portal.
+- [ ] Save to `deploy/secrets/apns_auth_key.p8` — the script enforces it
+      contains a real `-----BEGIN PRIVATE KEY-----` block.
+- [ ] Fill `APNS_AUTH_KEY_ID`, `APNS_TEAM_ID`, `APNS_TOPIC` (bundle ID) in
+      `deploy/prod.env`.
+- [ ] Decide `APNS_USE_SANDBOX` / `APNS_PRODUCTION` based on build target.
+
+### FCM (Android Push)
+
+- [ ] Create Firebase project + legacy server key (or migrate to HTTP v1 —
+      the code currently uses the legacy server key).
+- [ ] Save to `deploy/secrets/fcm_server_key.txt`.
+
+### SMTP (Email)
+
+- [ ] Provision SMTP credentials (Gmail app password, SES, Postmark, etc.).
+- [ ] Fill `EMAIL_HOST`, `EMAIL_PORT`, `EMAIL_HOST_USER`,
+      `DEFAULT_FROM_EMAIL`, `EMAIL_USE_TLS` in `deploy/prod.env`.
+- [ ] Save the password to `deploy/secrets/email_host_password.txt`.
+- [ ] Verify SPF, DKIM, DMARC on the sending domain if you care about
+      deliverability.
+
+### Registry (GHCR / other)
+
+- [ ] Create a personal access token with `write:packages` + `read:packages`.
+- [ ] Fill `REGISTRY`, `REGISTRY_NAMESPACE`, `REGISTRY_USERNAME`,
+      `REGISTRY_TOKEN` in `deploy/registry.env`.
+- [ ] Rotate the token on a schedule (quarterly at minimum).
+
+### Apple / Google IAP (optional)
+
+- [ ] Apple: create App Store Connect API key, fill the `APPLE_IAP_*` vars.
+- [ ] Google: create a service account with Play Developer API access,
+      store JSON at a path referenced by `GOOGLE_IAP_SERVICE_ACCOUNT_PATH`.
+
+---
+
+## Recurring Operations
+
+### Secret Rotation
+
+After any compromise, annually at minimum, and when a team member leaves:
+
+1. Generate the new value (e.g. `openssl rand -base64 32 > deploy/secrets/secret_key.txt`).
+2. `./.deploy_prod` — creates a new versioned Swarm secret and redeploys
+   services to pick it up.
+3. The old secret lingers until `SECRET_KEEP_VERSIONS` bumps it out (see
+   README "Secret Versioning & Pruning").
+4. For external creds (Neon, B2, APNS, etc.) rotate at the provider first,
+   update the local secret file, then redeploy.
+
+### Backup Drills
+
+- [ ] Quarterly: pull a Neon backup, restore to a scratch project, boot a
+      staging stack against it, verify login + basic reads.
+- [ ] Monthly: spot-check that B2 objects are actually present and the
+      app key still works.
+- [ ] After any schema change: confirm PITR coverage includes the new
+      columns before relying on it.
+
+### Certificate Management
+
+- TLS is terminated by Cloudflare today, so there are no origin certs to
+  renew. If you ever move TLS on-origin (Traefik, Caddy), automate renewal
+  — don't add it to this list and expect it to happen.
+
+### Multi-Arch Builds
+
+`./.deploy_prod` builds for the host arch. If target ≠ host:
+
+- [ ] Enable buildx: `docker buildx create --use`.
+- [ ] Install QEMU: `docker run --privileged --rm tonistiigi/binfmt --install all`.
+- [ ] Build + push images manually per target platform.
+- [ ] Run `SKIP_BUILD=1 ./.deploy_prod` so the script just deploys.
+
+### Node Maintenance / Rolling Upgrades
+
+- [ ] `docker node update --availability drain <node>` before OS upgrades.
+- [ ] Reboot, verify, then `docker node update --availability active <node>`.
+- [ ] Re-converge with `docker stack deploy -c swarm-stack.prod.yml honeydue`.
+
+---
+
+## Incident Response
+
+### Redis Node Dies
+
+Named volume is per-node and doesn't follow. Accept the loss:
+
+1. Let Swarm reschedule Redis on a new node.
+2. In-flight Asynq jobs are lost; retry semantics cover most of them.
+3. Scheduled cron events fire again on the next tick (hourly for smart
+   reminders and daily digest; daily for onboarding + cleanup).
+4. Cache repopulates on first request.
+
+### Deploy Rolled Back Automatically
+
+`./.deploy_prod` triggers `docker service rollback` on every service if
+`DEPLOY_HEALTHCHECK_URL` fails. Diagnose with:
+
+```bash
+ssh <manager> docker stack services honeydue
+ssh <manager> docker service logs --tail 200 honeydue_api
+# Or open an SSH tunnel to Dozzle: ssh -L 9999:127.0.0.1:9999 <manager>
+```
+
+### Lost Ability to Deploy
+
+- Registry token revoked → regenerate, update `deploy/registry.env`, re-run.
+- Manager host key changed → verify legitimacy, update `~/.ssh/known_hosts`.
+- All secrets accidentally pruned → restore the `deploy/secrets/*` files
+  locally and redeploy; new Swarm secret versions will be created.
+
+---
+
+## Known Gaps (Future Work)
+
+- No dedicated `cmd/migrate` binary — migrations run at API boot (see
+  README §10). Large schema changes still need manual coordination.
+- `asynq.Scheduler` has no leader election; `WORKER_REPLICAS` must stay 1
+  until we migrate to `asynq.PeriodicTaskManager` (README §9).
+- No Prometheus / Grafana / alerting in the stack. `/metrics` is exposed
+  on the API but nothing scrapes it.
+- No automated TLS renewal on-origin — add if you ever move off Cloudflare.
+- No staging environment wired to the deploy script — `DEPLOY_TAG=<sha>`
+  is the closest thing. A proper staging flow is future work.
