+## Features
+
+### Company Dashboard
+- Live table of all employees sorted by active CPAS points (highest risk first)
+- Summary stat cards: total employees, elite standing (0 pts), with active points, at-risk count, highest active score
+- **At-risk badge**: flags employees within 2 points of the next tier escalation
+- Search/filter by name, department, or supervisor
+- Click any employee name to open their full profile modal
+
+### Violation Form
+- Select existing employee or enter new employee by name
+- **Employee intelligence**: shows current CPAS standing badge and 90-day violation count before submitting
+- Violation type dropdown grouped by category; shows prior 90-day counts inline
+- **Recidivist auto-escalation**: if an employee has prior violations of the same type, points slider auto-sets to maximum per policy
+- Repeat offense badge with prior count displayed
+- Context-sensitive fields (time, minutes late, amount, location, description) shown only when relevant to violation type
+- **Tier crossing warning** (TierWarning component): previews what tier the new points would push the employee into before submission
+- Point slider for discretionary adjustments within the violation's min/max range
+- One-click PDF download immediately after submission
+
+### Employee Profile Modal
+- Full violation history with resolution status
+- Negate / restore individual violations (soft delete with resolution type + notes)
+- Hard delete option for data entry errors
+- PDF download for any historical violation record
+
+### CPAS Tier System
+
+| Points | Tier | Label |
+|--------|------|-------|
+| 0–4    | 0–1  | Elite Standing |
+| 5–9    | 1    | Realignment |
+| 10–14  | 2    | Administrative Lockdown |
+| 15–19  | 3    | Verification |
+| 20–24  | 4    | Risk Mitigation |
+| 25–29  | 5    | Final Decision |
+| 30+    | 6    | Separation |
+
+Scores are computed over a **rolling 90-day window** (negated violations excluded).
+
+### PDF Generation
+- Puppeteer + system Chromium (bundled in Docker image)
+- Generated on-demand per violation via `GET /api/violations/:id/pdf`
+- Filename: `CPAS_<EmployeeName>_<IncidentDate>.pdf`
+- PDF captures prior active points **at the time of the incident** (snapshot stored on insert)

-## Phases
+---
-- [x] Phase 1 — Container scaffold, SQLite schema, base React form
+
-- [ ] Phase 2 — Employee history, prior violation highlighting
+## Database Schema
-- [ ] Phase 3 — Puppeteer PDF generation
+
-- [ ] Phase 4 — Dashboard, CPAS scores, tier warnings
+Three tables + one view:
-- [ ] Phase 5 — Recidivist point auto-suggest
+
+- **`employees`** — id, name, department, supervisor
+- **`violations`** — full incident record including `prior_active_points` snapshot at time of logging
+- **`violation_resolutions`** — resolution type, details, resolved_by (linked to violations)
+- **`active_cpas_scores`** (view) — sum of points for non-negated violations in rolling 90 days, grouped by employee
+
+---
+
+## Roadmap
+
+### ✅ Completed
+
+| Phase | Feature | Description |
+|-------|---------|-------------|
+| 1 | Container scaffold | Docker multi-stage build, Express server, SQLite schema |
+| 1 | Base violation form | Employee fields, violation type, incident date, point submission |
+| 2 | Employee intelligence | Live CPAS standing badge and 90-day count shown before submitting |
+| 2 | Prior violation highlighting | Violation dropdown annotates types with 90-day recurrence counts |
+| 2 | Recidivist auto-escalation | Points slider auto-maximizes on repeat same-type violations |
+| 2 | Violation history | Per-employee history list with resolution status |
+| 3 | PDF generation | Puppeteer/Chromium PDF per violation, downloadable immediately post-submit |
+| 3 | Prior-points snapshot | `prior_active_points` captured at insert time for accurate historical PDFs |
+| 4 | Company dashboard | Sortable employee table with live tier badges and at-risk flags |
+| 4 | Stat cards | Summary counts: total, clean, active, at-risk, highest score |
+| 4 | Tier crossing warning | Pre-submit alert when new points push employee to next tier |
+| 4 | Employee profile modal | Full history, negate/restore, hard delete, per-record PDF download |
+| 4 | Negate & restore | Soft-delete violations with resolution type + notes, fully reversible |

+
+### 🔲 Proposed
+
+#### Reporting & Analytics
+- **Violation trends chart** — line/bar chart of violations per day/week/month, filterable by department or supervisor; useful for identifying systemic patterns vs. individual incidents
+- **Department heat map** — grid view showing violation density and average CPAS score by department; helps supervisors identify team-level risk
+- **Expiration timeline** — visual showing which active violations will roll off the 90-day window and when, so supervisors can anticipate tier drops
+- **CSV / Excel export** — bulk export of violations or dashboard data for external reporting or payroll integration
+
+#### Employee Management
+- **Employee edit / merge** — ability to update employee name, department, or supervisor without losing history; merge duplicate records created by name typos
+- **Supervisor view** — scoped dashboard showing only the employees under a given supervisor, useful for multi-supervisor environments
+- **Employee notes / flags** — free-text notes attached to an employee record (e.g. "on PIP", "union member") visible in the profile modal without affecting scoring
+
+#### Violation Workflow
+- **Acknowledgment signature field** — a "received by employee" name/date field on the violation form that prints on the PDF, replacing the blank signature line
+- **Draft / pending violations** — save a violation as draft before finalizing, useful when incidents need review before being officially logged
+- **Violation amendment** — edit a submitted violation's details (not points) with an audit trail, rather than delete-and-resubmit
+- **Bulk violation import** — CSV import for migrating historical records from paper logs or a prior system
+
+#### Notifications & Escalation
+- **Tier escalation alerts** — email or in-app notification when an employee crosses into Tier 2+ so the relevant supervisor is automatically informed
+- **Scheduled summary digest** — weekly email to supervisors listing their employees' current standings and any approaching tier thresholds
+- **At-risk threshold configuration** — make the "at-risk" warning threshold (currently hardcoded at 2 pts) configurable per deployment
+
+#### Infrastructure & Ops
+- **Multi-user auth** — simple login with role-based access (admin, supervisor, read-only); currently the app has no auth and is assumed to run on a trusted internal network
+- **Audit log** — immutable log of all creates, negates, restores, and deletes with timestamp and acting user, stored separately from the violations table
+- **Automated DB backup** — cron job or Docker health hook to snapshot `/data/cpas.db` to a mounted backup volume or remote location on a schedule
+- **Dark/light theme toggle** — the UI is currently dark-only; a toggle would improve usability in bright environments
+
+---
+
+*Proposed features are suggestions based on common HR documentation workflows. Priority and implementation order should be driven by actual operational needs.*
