fix(side-effects): keep non-prod off Slack and 3CX (DEV-306) (#287)

* style: apply formatter

 A recurring weekly schedule assigns employees to after-hours phone duty. Weekend shifts are split into Day (8am-5pm) and Night (5pm-8am). Any unassigned shift shows as **Available** in Slack with a pickup button. When someone picks up or drops a shift for today, the 3CX queue is updated immediately. Future changes take effect when the ring scheduler runs at 8am daily and 5pm on weekends.
 
+The work week runs Sunday through Saturday, matching payroll. A Saturday night shift (5pm Saturday through 8am Sunday) stays in the Saturday week. Sunday day and Sunday night open the next week. The Monday 7am post shows the week that started the day before, plus the following week, and the pay summary covers the previous Sunday through Saturday.
+
 The weekly schedule post is updated live when shifts change, and the previous week's post is automatically deleted when the new one goes out.
 
 The bot also has an **About** page: open the bot in Slack and click its **Home** tab to see what it does, the full command list, and the latest "What's New" (see [Releases & Versioning](#releases--versioning)).
 
+Employees can do the same pick, drop, swap, and admin work from the internal portal After Hours pages. Slack DMs for swaps and late pickups still go out. App Home admin modals stay as they are.

+Header: `Authorization: Bearer {token}`. Missing or wrong token is 401. Invalid JSON or fields is 400. A secret-read failure is 503.
+
+`email` is optional so existing Paychex syncs keep working. Portal identity looks up that email (case-insensitive) against the signed-in Google account. Without it, the portal shows an unlinked roster message. Admin access is still the Slack IDs in `admin_users` after the email lookup.
+
+### Portal HTTP API
+
+The internal portal SPA calls this API with the Cognito ID token from `GET /api/auth/meals-token`. CORS allows `https://internal.seahaven.com`, `https://internal.dev.seahaven.com`, and local Vite.
+
+| Method | Path | Who |
+|---|---|---|
+| GET | `/api/shifts?week=this\|next` | Linked employee; unlinked Google accounts get `{linked:false}` |

+Set portal `VITE_SHIFTS_API_BASE` to Terraform output `api_origin`. Set HCP variables `portal_cognito_issuer` and `portal_cognito_audience` (and `portal_cognito_extra_trust` if the portal has separate dev and prod pools).
+
+Set processor `AFTERHOURS_BASE_URL` to the Terraform output `api_origin` (HCP variable `afterhours_base_url` on `paychex-integrations-prod`). That value is the API origin only. Do not append `/roster`. Flip it at cutover after DynamoDB is copied, not before.
+
+Daily `afterhours-roster-sync` still owns the 3CX `DEFAULT` group at 6am ET: rows absent from that group are deleted. Hire is safe because 3CX create (into `DEFAULT`) happens before the roster PUT. An HTTP-only row that is not in that group will be removed on the next sync. Sync preserves `slack_user_id` on existing rows and does not overwrite a just-created API row's Slack id.
+
+Token rotation is a maintenance-window action. The Lambda caches the token per execution environment. Update `afterhours-shift-manager/roster-api-token` and `paychex-integrations/afterhours-roster-token` together, then recycle `afterhours-roster-api`. Updating only one copy, or recycling environments out of order, causes 401s until both sides match.

 Without this step, the Slack bot still works — it invokes the 3CX scheduler Lambda directly for same-day changes. Future-date overrides would only take effect if the scheduler reads DynamoDB.
 
+## 8. Prod cutover (PLAT-74)
+
+Avoid Monday 06:00-08:00 ET and any holiday 08:00/17:00 ET window. Dry-run the
+scripts first (`--execute` is required for writes).
+
+1. Merge this repo's PR (SAM CD is gone). First HCP apply is the bootstrap
+   window above with `schedules_enabled=false`.
+2. Copy DynamoDB `afterhours-shifts` mgmt → prod. Verify item counts:
+   `python scripts/cutover/copy_dynamodb.py --src-profile mgmt --dst-profile prod`
+   then `--execute`.
+3. Confirm secrets in prod. `copy_secrets.py` writes Slack bot token, Slack
+   signing secret, and roster-api-token into empty Terraform shells and skips
+   dest names that already have a value. It never writes 3CX secrets:
+   `python scripts/cutover/copy_secrets.py --src-profile mgmt --dst-profile prod`
+   then `--execute`. Strip trailing newlines is built in.
+4. GHA `workflow_dispatch` (or the merge deploy; re-run if it raced apply) to
+   overwrite stubs.
+5. Recreate outstanding future `holiday-activate-*` / `holiday-deactivate-*`
+   in prod against the new router ARN and scheduler role:
+   `python scripts/cutover/recreate_holiday_schedules.py --src-profile mgmt --dst-profile prod`
+6. Instant cut: Slack Request URL → prod `/slack/events`; Paychex HCP variable
+   `afterhours_base_url` on `paychex-integrations-prod` → prod `api_origin`;
+   `schedules_enabled=true` via a terraform-only merge; disable mgmt EventBridge.
+   Smoke: Slack `/oncall`, roster PUT/DELETE, weekly-post SendMessage (or
+   simulate-principal-policy plus one smoke message), ring-scheduler invoke,
+   holiday GetSchedule.
+7. Seal auto-apply on. Delete the mgmt SAM stack. Remove the mgmt SQS principal
+   from `paychex-checkcomponents`. Update Confluence AWS Architecture Map and
+   check PLAT-71 item 4.
+
+Do not dual-run 3CX writers. Do not flip `afterhours_base_url` before DynamoDB
+is copied.

+## 9. Fargate cutover (PLAT-216)
+
+Completed 2026-09-21. Live path is ECS Fargate behind
+`https://afterhours.seahaven.com` (dev: `https://afterhours.dev.seahaven.com`).
+Slack Request URL, Paychex `AFTERHOURS_BASE_URL`, and portal `VITE_SHIFTS_API_BASE`
+point at those hosts. Jobs use EventBridge Scheduler → SQS (`ecs_schedules_enabled=true`,
+Lambda EventBridge `schedules_enabled=false`). Public DNS is out of band in the
+mgmt `seahaven.com` zone and the external-dev `dev.seahaven.com` zone.

+Employee self-service plus admin After Hours in `internal-portal`. Slack stays.
+
+Decisions:
+
+- After Hours is a primary nav item (`/shifts`, `/shifts/admin`).
+- Identity is roster `email` from Paychex `PUT /roster` (optional for backward compatibility; portal mapping needs it). Admin remains `get_admin_users()` Slack IDs after that lookup.
+- Swap and late-pickup are in-portal pending actions and still DM on Slack.
+- Slack App Home admin modals stay as-is.

+override coverage, open or clear a shift, manage holidays, and approve late
+pickups there. Swap and late-pickup still send Slack DMs. Slack App Home admin
+modals are unchanged.

+Portal identity is the roster email on Paychex `PUT /roster` (optional so existing
+syncs keep working). Admin access is still the Slack IDs in `admin_users` after
