docs: improve contact information for clarity and professionalism

- Implemented Form301 component for displaying OSHA Form 301 equivalent, including employee and case information.
- Created Osha component to manage OSHA recordkeeping, including tabs for 300 Log, 300A Summary, Hours & rates, and Submit to OSHA.
- Added functionality for printing and downloading CSV files for OSHA submissions.
- Integrated loading and error handling states for data fetching.

 ## Code guidelines
 
 - **TypeScript** everywhere; avoid `any`.
-- **Structure:** routes go in `src/pages/`, reusable UI in `src/components/`, and types and domain logic in `src/lib/` (no React components there).
+- **Structure:** routes go in `src/pages/`, reusable UI in `src/components/`, and types and domain logic in `src/lib/` (no React components there). API routes go in `server/routes/`, one file per resource. Enums and request schemas used by both sides live in `shared/`.
+- **Server code runs without a build step** (Node strips the types), so use only erasable TypeScript: no `enum`, `namespace` or constructor parameter properties, and include the `.ts` extension in relative imports. `npm run typecheck` enforces this.
+- **Database changes:** edit `server/db/schema.ts`, then run `npm run db:generate` and commit the generated migration. Migrations run automatically when the server starts.
+- **Permissions:** every API route must check the signed-in user's role and organization. Add a test showing a lower role is refused.
 - **Styling:** Tailwind CSS. Use the theme tokens in `src/index.css` (`text-ink`, `bg-coral`, `border-line`, …) rather than new hex values; add a token if a color is reused.
 - **Tests:** put domain logic in `src/lib/` with a unit test next to it (`*.test.ts`). Cover user-facing flows with a component test or a Playwright test in `e2e/`.
+- **Translations:** user-facing text on worker screens lives in `src/i18n/en.ts` with the Spanish in `src/i18n/es.ts`. TypeScript and a test fail if a Spanish entry is missing, so add both together. If you can't translate, open the pull request anyway and ask for help.
 - **Accessibility:** every form control needs a label, and every icon-only button needs an `aria-label`. Shop-floor users may be on gloves-on touchscreens, so keep touch targets generous.
 - **Safety data:** incident and injury records can contain medical and personal information. Never log them, and never add third-party scripts, fonts or analytics that would send data off the server.

 ## Getting started
 
-Requires Node.js 22.12 or later (see `.nvmrc`).
+Requires Node.js 22.18 or later (see `.nvmrc`). No database install is needed for development: the server uses embedded PostgreSQL (PGlite) stored in `./data/`.
 
 ```sh
 npm install
-npm run dev
+npm run db:seed   # optional: demo organization, sites, users and incidents
+npm run dev       # web app on http://localhost:5173, API on http://localhost:3000
 ```
 
+`npm run db:seed` also loads a year of realistic history so the dashboards and OSHA log have data. Demo users: `admin@example.com`, `manager@example.com`, `supervisor@example.com` and `reporter@example.com`, all with password `safetylog-demo`. Without seeding, opening the app takes you to first-run setup.
+
+In development, emails (sign-in links, invitations, notifications) are printed in the terminal running the server.
+
+Settings are read from environment variables or a `.env` file; see [.env.example](.env.example).
+
+## Running in production
+
+```sh
+cp .env.example .env    # set POSTGRES_PASSWORD, and PUBLIC_URL if not localhost
+docker compose up -d --build
+```
+
+This runs the app and PostgreSQL. The app applies database migrations on startup and serves the web app and API on port 3000. Uploaded photos are kept in the `app-data` volume.
+
+- Use HTTPS (for example behind a reverse proxy) and set `PUBLIC_URL` to the `https://` address so session cookies are marked secure and email links point to the right place.
+- Set `SMTP_URL` and `MAIL_FROM` so sign-in links, invitations and notifications are delivered.
+- Set `TZ` to the plant's time zone (e.g. `America/Chicago`) so due dates and daily reminders follow local days.
+- Back up both volumes: `db-data` (PostgreSQL) and `app-data` (uploads).
+- Installing the app on phones and opening it offline needs HTTPS (browsers require it for service workers). Over plain HTTP everything else works, and reports made while offline are still queued once the page is open.
+
+## OSHA recordkeeping
+
+On an incident, safety managers add each injured or ill person and answer a short set of questions; the app decides whether the case is recordable under 29 CFR 1904 and how it's classified, flags injuries that must be reported to OSHA within 8 or 24 hours, and builds the Form 300 Log, 300A Summary and 301 reports per site. Enter monthly hours and headcount for incidence rates (TRIR, DART), add establishment details on the Locations page, and download the CSV files for OSHA's Injury Tracking Application from **OSHA log → Submit to OSHA**.
+
+The app helps apply OSHA's rules consistently, but it is not legal advice: the employer remains responsible for its records.
+
+## Shop-floor reporting
+
+- **Kiosk tablets and QR codes:** in **Settings → Reporting links**, create a link. Open it on a shared tablet for a kiosk, or print QR codes for it from **Locations → QR codes**. Anyone can then report without an account; the link can't read anything and can be revoked at any time.
+- **Offline:** reports made without a connection are kept on the device and sent automatically when it returns.
+- **Spanish:** use the language button (sidebar, sign-in page or kiosk header). The choice is remembered on that device.
+
+For a very small single-machine install, the app image also runs on its own with embedded PostgreSQL: `docker run -p 3000:3000 -v safetylog-data:/app/data <image>`.

+# API reference
+
+JSON over HTTP under `/api`. Authentication uses a session cookie (`safetylog_session`, http-only) set by setup, sign-in, emailed links and password changes.
+
+Request bodies are validated against [`shared/schemas.ts`](../shared/schemas.ts); response shapes are in [`shared/api-types.ts`](../shared/api-types.ts). Errors look like `{ "error": "message" }`; validation errors (400) also include `issues: [{ path, message }]`.
+
+Roles, from least to most privileged: `reporter` < `supervisor` < `safety_manager` < `admin`. A role can do everything the roles below it can.
+
+Browsers must send an `Origin` header matching the site on form/multipart and body-less requests (all browsers do); JSON requests are protected by CORS.
+
+## Setup and authentication
+
+| Method | Path | Who | Notes |
+| --- | --- | --- | --- |
+| GET | `/api/health` | anyone | `{ ok: true }` |
+| GET | `/api/setup` | anyone | `{ needsSetup }`: true until the first admin exists |
+| POST | `/api/setup` | anyone, once | `{ organizationName, name, email, password }`. Creates the organization and an admin, signs them in. 409 afterwards |
+| POST | `/api/auth/login` | anyone | `{ email, password }`. 401 on bad credentials, 429 after 10 attempts per email in 15 minutes |
+| POST | `/api/auth/magic-link` | anyone | `{ email }`. Emails a single-use sign-in link (15 minutes). Always 204 |
+| POST | `/api/auth/magic-link/verify` | anyone | `{ token }`. Signs in |
+| POST | `/api/auth/password-reset` | anyone | `{ email }`. Emails a reset link (1 hour). Always 204 |
+| POST | `/api/auth/password-reset/confirm` | anyone | `{ token, newPassword }`. Sets the password, signs out other sessions, signs in. Also completes invitations |
+| POST | `/api/auth/logout` | anyone | Ends the session. 204 |
+| GET | `/api/auth/me` | signed in | `{ user, organization }` |
+| POST | `/api/auth/password` | signed in | `{ currentPassword, newPassword }`. Signs out all other sessions. 204 |
+
+Passwords need at least 10 characters. Email requests are limited to 5 per address per 15 minutes. Emailed links land on web pages (`/auth/magic`, `/auth/reset`) that POST the token, so link scanners in email systems can't use them up.

+| GET | `/api/users/assignable` | supervisor | Active users `{ id, name, role }`, for assigning leads and actions |
+| POST | `/api/users` | admin | `{ name, email, role, password? }`. Without `password` an invitation email is sent (link valid 7 days). Returns `{ user, invited }` |
+| PATCH | `/api/users/:id` | admin | `{ name?, role?, active?, password? }`. Deactivating or setting a password signs the user out. The last active admin can't be demoted or deactivated |
+
+## Sites and areas
+
+| Method | Path | Who | Notes |
+| --- | --- | --- | --- |
+| GET | `/api/sites` | signed in | Sites with their `areas` (flat list; build the tree from `parentId`). `?includeArchived=true` to include archived |

+## Incidents
+
+Addressed by number (`/api/incidents/42` is `INC-0042`). Numbers are sequential per organization with no gaps.
+
+**Visibility:** supervisors and above see every incident. Reporters see incidents they reported plus any where they're assigned a corrective action. Anything else answers 404.

+**List and export filters:** `page`, `pageSize` (1–100, default 25), `q` (title, description, location; `INC-0042` or `42` matches the number), `type`, `severity`, `status`, `siteId`.
+
+Send a random `clientId` (UUID) with each report. Resubmitting the same `clientId` returns the original report (200 instead of 201) instead of creating a duplicate, so devices can safely retry after a dropped connection.

+- `type`: `near_miss`, `hazard`, `injury`, `illness`, `property_damage`, `environmental`

+
+### Workflow
+
+`reported` → `triage` → `investigation` → `actions` → `verification` → `closed`. The rules live in [`shared/workflow.ts`](../shared/workflow.ts) and are enforced by the API.
+
+| From | To | Who | Condition |
+| --- | --- | --- | --- |
+| reported | triage | supervisor | |
+| triage | investigation | supervisor | |
+| triage | actions | supervisor | |
+| triage | closed | supervisor | Low or medium severity only |
+| investigation | actions | supervisor | At least one root cause |
+| actions | investigation | supervisor | |
+| actions | verification | supervisor | At least one action, none open or in progress |
+| verification | actions | safety_manager | |
+| verification | closed | safety_manager | Every (non-cancelled) action verified |
+| closed | investigation | safety_manager | Reopen |
+
+## Root causes, actions, attachments
+
+| Method | Path | Who | Notes |
+| --- | --- | --- | --- |
+| PATCH | `/api/root-causes/:id` | supervisor | `{ category?, description?, whys? }` |
+| DELETE | `/api/root-causes/:id` | supervisor | |
+| GET | `/api/actions` | signed in | `?scope=mine\|all` (`all` needs supervisor) and `?filter=open\|overdue\|done\|all`. Sorted by due date |
+| PATCH | `/api/actions/:id` | see notes | Supervisors: any field and status except `verified`. Safety managers: also `verified`. Assignees: only `status` among `open`, `in_progress`, `done` |
+| GET | `/api/attachments/:id` | can see the incident | The file, with a sandboxing Content-Security-Policy |
+| DELETE | `/api/attachments/:id` | uploader or supervisor | |
+
+Each action has `overdue: true` when it's open or in progress and its due date has passed (server time zone, `TZ`). Assignees get one email digest per day listing their actions due tomorrow or overdue.
+
+## Reporting links (kiosks and QR codes)
+
+Reporting links let people file reports without an account. Each has a token that can **only** create reports.
+
+| Method | Path | Who | Notes |
+| --- | --- | --- | --- |
+| GET | `/api/kiosks` | safety_manager | All links, including their tokens (to reprint QR codes) |
+| POST | `/api/kiosks` | safety_manager | `{ name, siteId? }`. `siteId` restricts the link to one site |
+| PATCH | `/api/kiosks/:id` | safety_manager | `{ name?, siteId?, revoked? }` |
+| GET | `/api/kiosk/config` | link token | Organization name, link name, and the sites/areas it may report on |
+| POST | `/api/kiosk/reports` | link token | Multipart: `report` (JSON: the create body minus `anonymous`, plus optional `reporterName`) and up to 5 `files`. Returns `{ reference, failedFiles }`. 30 reports per link per 10 minutes |
+
+The token goes in the `X-Kiosk-Token` header. Browsers can't send custom headers cross-site without a CORS preflight, which the API doesn't allow, so other websites can't submit through a link. Reports without `reporterName` are anonymous. Incidents filed this way have `channel: "kiosk"` and `kiosk: { id, name }`.
+
+The web app opens links at `/k/<token>`, optionally with `?site=<id>&area=<id>` to pre-fill the location (as QR codes do).
+
+## OSHA recordkeeping
+
+All endpoints need **safety_manager**: they hold confidential medical information. Other roles only see `injuredCount` on an incident. Rules are in [`shared/osha.ts`](../shared/osha.ts); section numbers refer to 29 CFR 1904.
+
+| Method | Path | Notes |
+| --- | --- | --- |

 ## Phase 1: Backend and data model
 
-- Entities: Organization, Site → Area (location tree), User, Role, Incident (type, severity, status, timestamps, reporter or anonymous), InjuredPerson and injury details, Attachment, Investigation, RootCause, CorrectiveAction, Comment, AuditLog, HoursWorked
+- [x] Database schema and first migration for all entities: Organization, Site → Area (location tree), User, Session, Incident, InjuredPerson, Attachment, Investigation, RootCause, CorrectiveAction, Comment, AuditLog, HoursWorked
-- Auth: email/password and magic links; SSO/OIDC later; role-based permissions
+- [x] First-run setup (creates the organization and first admin)
-- REST API with pagination, filtering and sequential incident numbering
+- [x] Email/password sign-in, sessions, change password, login rate limiting
+- [x] Role-based permissions (reporters see only their own reports)
+- [x] REST API: users, sites/areas, incidents with pagination, search, filters and gap-free sequential numbers (`INC-0001`); see [API.md](API.md)
+- [x] Audit log of every change
+- [x] Server tests (Vitest + in-memory PostgreSQL), demo seed data
+- [x] Dockerfile and `docker-compose.yml`
+- Moved to Phase 2: magic-link sign-in and password reset by email (both need the email sending built for notifications). SSO/OIDC stays "later".
 
 ## Phase 2: Core workflow (MVP)
 
-- Reporting that saves to the database, with photo upload
+- [x] Web app connected to the API: sign-in, first-run setup, every page on live data (demo data removed from the frontend)
-- Incident detail page: timeline, investigation, root-cause tools (5 Whys, fishbone), corrective actions (CAPA)
+- [x] Photo and PDF upload, checked by file content (not name), size-limited, served with a sandboxing security policy
-- Status workflow: Reported → Triage → Investigation → Corrective actions → Verification → Closed, with role-based transitions
+- [x] Magic-link sign-in, password reset by email, email invitations for new users (admins can also set passwords when there's no email)
-- "My actions" list and overdue tracking
+- [x] Incident detail page: details editing, activity log (comments + audit trail), investigation with 5 Whys and fishbone (6M) views, corrective actions (CAPA)
-- Email notifications: assignment, due dates, high-severity alerts
+- [x] Status workflow Reported → Triage → Investigation → Corrective actions → Verification → Closed, with role rules and guards (e.g. high severity can't skip investigation; closing needs every action verified), shared between API and UI
-- CSV and PDF export
+- [x] "My actions" and "All actions" lists with overdue tracking; assignees can update progress on their own actions
-- Dashboard metrics computed from real data
+- [x] Email notifications: high/critical alerts to safety managers, action assignment, daily due/overdue digest
+- [x] CSV export of the filtered register (protected against spreadsheet formula injection); print-friendly incident page for PDF via the browser
+- [x] Overview dashboard and Analytics computed from real data; Locations and Settings (people, roles, passwords) pages
+- [x] End-to-end tests run against the real server: full three-role lifecycle, sign-in, visibility rules, mobile reporting
 
 ## Phase 3: Shop-floor reporting
 
-- Installable PWA with offline queue (sync when connection returns)
+- [x] Installable app (web manifest, icons, service worker caching the app shell plus who-am-I and site lists)
-- Printable QR codes per area that pre-fill the location
+- [x] Offline outbox: reports and photos saved on the device, sent automatically on reconnect; duplicate-proof retries via a client-generated id; reports only sent for the user who made them; warning on sign-out with unsent reports
-- Kiosk mode and anonymous reporting
+- [x] Reporting links (managed in Settings): revocable tokens, optionally limited to one site, 30 reports per 10 minutes, photos included; kiosk page for shared tablets with large touch targets and auto-reset
-- Multi-language support, Spanish first
+- [x] Printable QR code sheets per site/area, for signed-in users or through a reporting link, with bilingual captions; scanning pre-fills the location
+- [x] Anonymous reporting from the app, the kiosk and QR codes
+- [x] English/Spanish: sign-in pages, navigation, report form, kiosk, My actions, offline messages; language toggle remembered per device; follows the browser language by default
+- [x] Tests: outbox (IndexedDB), translations complete, reporting links and duplicate-proof retries on the server, browser tests for offline sync, Spanish kiosk via QR, QR pre-fill and installability
 
 ## Phase 4: Compliance (US OSHA)
 
-- Recordability wizard; days away / restricted / transferred tracking
+- [x] Injured/ill people per incident with a live recordability check (1904.4–1904.11): covered worker, work-related, new case, general criteria, special cases; most-serious-outcome classification; 14-item first-aid list and privacy-case rules shown in context
-- OSHA 300, 300A and 301 form generation; privacy-case handling
+- [x] Day counts with the 180-day cap; days only counted when the matching outcome applies
-- ITA (Injury Tracking Application) CSV export
+- [x] Severe injury reporting (1904.39): 8-hour/24-hour deadline banner, email alert to safety managers, "reported to OSHA at" record
-- Hours worked per site per month; TRIR, DART and lost-time rates
+- [x] Form 300 Log (landscape print), Form 300A Summary with establishment details and certification block, printable Form 301 per case
+- [x] Establishment details per site (address, NAICS, EIN, type) with validation
+- [x] Monthly hours worked and headcount; TRIR, DART and LTIR
+- [x] ITA CSV exports for the 300A summary and 300/301 case data (no names), plus OSHA's own upload checks run in the app
+- [x] Tests: rules module unit tests, API tests incl. exact CSV output, browser test of the full recordkeeping flow
 
 ## Phase 5: Analytics
 
-- Trends, location breakdown, top root causes, corrective-action closure time
+- [x] One filter row (date range presets or custom, site, incident type) scoping every number and chart on the page
-- Leading vs lagging indicators; filters and saved dashboards
+- [x] Leading indicators: hazards & near misses reported, near misses per injury, triaged within 24 hours, actions completed on time; each compared with the previous period
+- [x] Lagging indicators: injuries, OSHA-recordable cases, rolling 12-month TRIR/DART, average days to close; OSHA rates by calendar year
+- [x] Charts: reports per week/month by kind, rolling OSHA rates, locations (sites, or areas within a site), root causes, weekday × hour heatmap, actions completed on time vs late
+- [x] Saved views (private, or shared by supervisors and above) on Analytics and the Incidents list
+- [x] Demo seed with a year of realistic history (deterministic)
+- [x] Tests: analytics computations (periods, groupings, rates, scoping), saved views, chart scale helper, browser tests

 ## Project setup
 
-- [ ] **Code of Conduct contact.** Replace the placeholder in [CODE_OF_CONDUCT.md](../CODE_OF_CONDUCT.md) with a reporting email address, ideally a project alias rather than a personal one.
+- [ ] **Code of Conduct contact.** [CODE_OF_CONDUCT.md](../CODE_OF_CONDUCT.md) uses `jay@equineform.com` for now. Change it to a project alias (e.g. `conduct@<project-domain>`) once the project has its own domain.
 - [ ] **Source code link.** The About page links to `https://www.equineform.com` for now (default in `src/lib/config.ts`, overridable with `VITE_SOURCE_URL`). Change it to the public git repository once one exists, and use the same URL for issue links in CONTRIBUTING.md.
 - [ ] **CI on Gitea.** Confirm Actions is enabled for the repository and a runner is registered, then check the first run of `.gitea/workflows/ci.yml` passes. Keep the Playwright container tag in the workflow in sync with `@playwright/test`.
 
+## Phase 1 follow-ups
+
+- [ ] **Test against real PostgreSQL.** Server tests use PGlite (PostgreSQL compiled to WebAssembly). Add a CI job with a `postgres` service container that runs the server tests against real PostgreSQL too.
+- [ ] **Docker build in CI.** Build the image in CI once a runner with Docker is available.
+- [ ] **Shared login rate limit.** The login limiter is in memory, so it resets on restart and isn't shared between processes. Fine for one container; move it to the database before running several app instances.
+
+## Phase 2 follow-ups
+
+- [ ] **Server-side PDF (later).** Decided 2026-10-06 to keep browser-generated PDFs for now: the "Print / PDF" button and print stylesheet are simpler and add no dependencies. Revisit if PDFs need to be produced automatically, e.g. attached to emails or archived on close.
+- [ ] **Email delivery (later).** Decided 2026-10-06 that the current behavior is fine for now: without `SMTP_URL`, emails print to the server log in development and are dropped (with a startup warning) in production. Later: configure SMTP for real deployments, add a "send test email" button for admins, and consider showing admins a warning in the app when email isn't set up.
+- [ ] **Notification preferences.** Everyone gets every email that applies to them. Add per-user opt-outs, and an alert-recipients setting per site.
+- [ ] **Edit corrective actions in the UI.** The API supports changing an action's title, assignee and due date; the incident page only offers status changes and adding new actions.
+- [ ] **HEIC thumbnails.** iPhone HEIC photos are stored and downloadable but browsers can't show them inline; convert to JPEG on upload.
+- [ ] **Session check console noise.** Signed-out visitors see one 401 in the browser console from the session check; harmless, but a `200 { user: null }` endpoint would be quieter.
+
+## Phase 3 follow-ups
+
+- [ ] **Translate manager screens.** Spanish currently covers what shop-floor workers use (sign-in, report form, kiosk, My actions, navigation). The incident page, investigation, dashboards, analytics, locations and settings are still English. Add their strings to `src/i18n/en.ts` and `es.ts`.
+- [ ] **Spanish emails.** Notification and sign-in emails are English only. Store a language preference per user and use it for emails.
+- [ ] **HTTPS for offline use.** Browsers only allow installing the app and the offline app shell over HTTPS (or localhost). Reports still queue offline over plain HTTP once the page is open, but the page itself can't load offline. Document a simple HTTPS setup (e.g. Caddy in front of the app) in the install guide.
+- [ ] **Have Spanish reviewed by a native speaker** familiar with plant safety terms (e.g. "casi accidente" for near miss, "planta" for site).
+- [ ] **Offline incident list.** Only reporting works offline; viewing incidents and actions needs a connection.
+
+## Phase 4 follow-ups
+
+- [ ] **Expert review of the OSHA rules.** `shared/osha.ts` encodes 29 CFR 1904 as plainly as possible with section references, but it should be reviewed by a recordkeeping professional before anyone relies on it. The app should say clearly that it assists, and the employer remains responsible.
+- [ ] **Deadline reminders.** Email safety managers in January to certify and post the 300A (Feb 1–Apr 30) and before the ITA submission deadline (March 2).
+- [ ] **Direct ITA submission.** OSHA offers an API for the Injury Tracking Application; submitting directly would remove the CSV download/upload step.
+- [ ] **Day counting from dates.** Calculate days away/restricted from start and return-to-work dates instead of typed counts.
+- [ ] **Employee access (1904.35).** Employees and their representatives may request the 300 Log (and their own 301). Add a way to produce those copies with privacy cases removed.
+- [ ] **OSHA rates on the dashboard.** Show TRIR/DART on Overview and Analytics, and trends over years.
+- [ ] **Translate the OSHA pages** along with the other manager screens.
+- [ ] **Other regions.** The data model keeps outcomes and case types separate from US-specific forms; UK RIDDOR or Canadian provincial rules could be added as further rule sets.
+
+## Phase 5 follow-ups
+
+- [ ] **Industry benchmarks.** Show the BLS average TRIR/DART for the site's NAICS code next to its own rates.
+- [ ] **Scheduled reports.** A weekly or monthly email digest of the indicators for safety managers.
+- [ ] **Chart export.** Download a chart as an image, or print the whole Analytics page as a report (print styles are in place for most of it).
+- [ ] **Dark mode.** The app is light-only; if a dark theme is added, the chart colors need their dark-mode steps validated against the dark surface.
+- [ ] **Translate Analytics** with the other manager screens.
+
 ## Done
 
+- [x] Docker verified 2026-10-06 (Docker 29.8, Compose v5.5): image builds (~315 MB), `docker compose up` with PostgreSQL 18 passes setup → sign-in → report smoke test; data and sessions survive `down`/`up`; clean shutdown; healthcheck healthy; runs as non-root; standalone PGlite container works; `Secure` cookie with an `https://` PUBLIC_URL; web app loads with no errors.
