+# Contributing to WarpBox
+
+WarpBox is a small Go application with server-rendered HTML, vanilla
+JavaScript, static CSS, local filesystem storage, and BadgerDB metadata. Keep
+changes boring, readable, and easy to review.
+
+## Setup
+
+Requirements:
+
+- Go 1.23 or newer, matching `go.mod`.
+- No frontend toolchain. Do not add npm, Vite, React, TypeScript, Sass,
+  Tailwind, or a JavaScript build step for cleanup work.
+
+Run the app:
+
+```bash
+go run ./cmd run
+```
+
+Run on another address:
+
+```bash
+go run ./cmd run --addr :3000
+```
+
+## Tests and Checks
+
+Run tests:
+
+```bash
+./test.sh
+```
+
+Run formatting, vet, and tests:
+
+```bash
+./check.sh
+```
+
+Both scripts honor `GO_BIN`:
+
+```bash
+GO_BIN=/path/to/go ./check.sh
+```
+
+If a command cannot run in your environment, say why and include the command
+that should be run locally.
+
+## Commit Style
+
+Use Conventional Commits:
+
+```text
+type(scope): short imperative subject
+```
+
+Types:
+
+- `feat` user-visible feature
+- `fix` bug fix
+- `refactor` behavior-preserving code change
+- `test` tests only
+- `docs` documentation only
+- `style` formatting or CSS-only visual style when behavior unchanged
+- `chore` tooling, dependency, build, housekeeping
+- `perf` performance change
+- `ci` CI config
+
+Rules:
+
+- Keep subject at 72 characters or less, preferably 50 or less.
+- Use imperative mood.
+- Keep one concern per commit.
+- Make cleanup commits behavior preserving unless the subject says `fix`.
+- Mention tests run in the PR description or commit body when useful.
+
+Examples:
+
+```text
+docs(contributing): add cleanup rules
+refactor(server): split upload handlers
+fix(config): reject negative expiry values
+```
+
+## Code Review Expectations
+
+Reviews should focus on behavior, safety, and maintainability:
+
+- Confirm routes, environment variables, API response shapes, manifest fields,
+  and storage layout remain compatible unless the change explicitly updates
+  them.
+- Check that cleanup keeps behavior unchanged and is small enough to review.
+- Prefer narrow helpers and clear file ownership over clever abstraction.
+- Ask for tests when behavior changes or risk is not obvious.
+- Call out missing checks, unclear edge cases, concurrency risks, and security
+  risks.
+
+## PR Checklist
+
+Before opening or merging a PR:
+
+- Scope is limited to one concern.
+- Runtime behavior is unchanged for cleanup PRs.
+- Public routes are unchanged unless intentional.
+- Environment variables are unchanged unless intentional.
+- API response shapes are unchanged unless intentional.
+- Manifest JSON field names are unchanged unless intentional.
+- Storage directory layout is unchanged unless intentional.
+- No frontend build tooling was added.
+- Tests or checks run are listed.
+
+## Coding Standards Summary
+
+- Go: small functions, clear errors, stable exported names, no unrelated
+  package moves.
+- JavaScript: vanilla browser scripts, no build step, explicit state ownership,
+  small modules when files are split.
+- CSS: keep shared styles shared, page styles page-scoped, avoid duplicated
+  popup/window rules.
+- Templates: keep server-rendered HTML simple and routes stable.
+- Comments: explain behavior rules, edge cases, concurrency, security, or
+  product choices. Do not restate obvious code.
+
+See [DEVELOPMENT.md](DEVELOPMENT.md) for cleanup rules.

+# WarpBox Development Rules
+
+This guide exists for contributors and LLM agents doing behavior-preserving
+cleanup. It complements [docs/tech.md](docs/tech.md), which maps the current
+implementation.
+
+## Cleanup Principles
+
+- Keep systems boring and obvious.
+- Prefer short files grouped by one clear responsibility.
+- Prefer narrow helpers over clever abstraction.
+- Keep related functions physically close.
+- Split files when one file mixes multiple domains.
+- Avoid huge utility drawers where unrelated helpers gather.
+- Do behavior-preserving cleanup before feature work.
+- Use tests before and after each cleanup slice.
+
+Cleanup is not feature work. Do not change runtime behavior unless the task
+explicitly says to fix behavior.
+
+## File Responsibility Goals
+
+Files should not mix:
+
+- UI and state.
+- Transport and rendering.
+- Validation and routing.
+- Filesystem operations and business rules.
+- Admin workflows and public box workflows.
+
+When a file is large and contains multiple concerns, prefer splitting by
+responsibility. Use comment regions only when a file is cohesive and splitting
+would make it harder to follow.
+
+Previously split cleanup targets:
+
+- `static/js/app.js` now bootstraps `static/js/upload/`.
+- `static/css/upload.css` now lives under `static/css/upload/` and `static/css/components/`.
+- `lib/server/handlers.go` is split by handler responsibility.
+- `lib/boxstore/store.go` is split by storage responsibility.
+- `lib/server/admin.go` is split by admin responsibility.
+- `lib/config/config.go` is split by config responsibility.
+
+Do not refactor multiple systems in one cleanup slice.
+
+## Comment and JSDoc Guidance
+
+Add comments for:
+
+- Behavior rules that are easy to break.
+- Edge cases.
+- Concurrency or background worker behavior.
+- Security-sensitive choices.
+- Non-obvious product decisions.
+
+Avoid comments that restate code. Prefer clear names and small functions first.
+Use JSDoc only when it clarifies non-obvious inputs, outputs, or side effects.
+
+## Go Rules
+
+- Keep public routes stable.
+- Keep environment variable names stable.
+- Keep API response shapes stable.
+- Keep manifest JSON field names stable.
+- Keep storage directory layout stable.
+- Keep handler files focused on one handler category.
+- Keep route registration separate from validation and business logic.
+- Return clear wrapped errors when context helps debugging.
+- Avoid package moves unless the cleanup slice is specifically about package
+  ownership.
+- Run `gofmt`, `go vet`, and `go test` through `./check.sh`.
+
+Server handler files:
+
+- `pages.go`
+- `downloads.go`
+- `uploads.go`
+- `box_auth.go`
+- `validation.go`
+- `retention.go`
+
+Keep `lib/server/handlers.go` absent unless there is a deliberate reason to
+reintroduce a cohesive handler file.
+
+## JavaScript Rules
+
+- Use vanilla JavaScript only.
+- Do not add a build step.
+- Keep browser scripts loaded directly by templates.
+- Avoid new globals; centralize mutable upload state when splitting.
+- Keep DOM queries/rendering separate from API calls and upload orchestration.
+- Prefer an action map over long action `if` chains when cleaning event code.
+- Share generic UI helpers through `static/js/warpbox-ui.js`.
+- Preserve existing data attributes and template contracts unless explicitly
+  changing behavior.
+
+Target upload split when that cleanup slice is chosen:
+
+- `static/js/upload/state.js`
+- `static/js/upload/dom.js`
+- `static/js/upload/files.js`
+- `static/js/upload/api.js`
+- `static/js/upload/upload-flow.js`
+- `static/js/upload/options.js`
+- `static/js/upload/popups.js`
+- `static/js/upload/terminal.js`
+- `static/js/upload/events.js`
+- `static/js/app.js` as bootstrap only
+
+## CSS Rules
+
+- Keep shared styles in shared files.
+- Keep page-specific styles page-scoped.
+- Avoid duplicated popup, toast, button, and window rules.
+- Use page prefixes for page styles:
+  - `upload-`
+  - `box-`
+  - `admin-`
+- Keep visual changes out of behavior-preserving cleanup unless the cleanup
+  slice is CSS-only.
+- Preserve template class names unless the same slice updates every use.
+
+Target CSS split when that cleanup slice is chosen:
+
+- `base.css`
+- `window.css`
+- `components/buttons.css`
+- `components/popups.css`
+- `components/toast.css`
+- `upload/layout.css`
+- `upload/queue.css`
+- `upload/options.css`
+- `upload/dialogs.css`
+- `upload/responsive.css`
+- `box.css`
+- `admin.css`
+
+## Template Rules
+
+- Keep server-rendered HTML simple.
+- Do not rename public routes during cleanup.
+- Do not change form field names or data attributes unless the matching Go and
+  JavaScript code changes in the same slice.
+- Keep static CSS and JS loading explicit.
+- Avoid hidden behavior changes through template conditionals.
+
+Current loading model:
+
+- Go loads templates from `templates/*.html`.
+- Gin serves `/static` from `./static` with gzip middleware.
+- Templates link CSS directly from `/static/css/...`.
+- Templates load browser JavaScript directly from `/static/js/...`.
+- There is no JavaScript or CSS build step.
+
+## Safety Rules
+
+- Inspect repository structure before editing.
+- Identify relevant files for the current cleanup slice.
+- Identify how JavaScript and CSS are loaded before frontend cleanup.
+- Identify available test/check commands before editing.
+- Summarize the intended change before editing.
+- Make the smallest useful change.
+- Do not rename public routes.
+- Do not rename environment variables.
+- Do not change API response shapes.
+- Do not change manifest JSON field names.
+- Do not change storage directory layout.
+- Do not add frontend tooling during cleanup.
+- Do not rewrite working code just to make it look different.
+- Do not mix unrelated cleanup areas in one change.
+- Do not claim tests passed unless they actually ran.
+
+## Definition of Done
+
+For each cleanup slice:
+
+- Change scope matches one cleanup area.
+- Behavior is unchanged unless the slice is explicitly a fix.
+- Files have clearer responsibility than before.
+- Comments explain only non-obvious rules or risks.
+- Tests or checks were run and recorded.
+- Any failed command is recorded with the exact reason.
+- Next cleanup slice is clear.

+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of

 # WarpBox
 
 WarpBox is a small, self-hosted file sharing app with temporary upload boxes,
-simple download links, optional passwords, ZIP downloads, and a very deliberate
-retro desktop mood.

 It is meant to feel quick: pick files, choose how long the box should live,
 upload, and share the link.

+## Docker / Podman
+
+If you are using Podman, please pay attention in the [docker-compose.yml](./docker-compose.example.yml) example
+file that has been provided, there's comments in regards to differences between the two.
+
+
+When it comes to building the image, please make sure that you basically set the `--format docker` in the podman
+build command, otherwise it won't have HealthChecks and other issues might arise.
+
+Tip: Put the following in `~/.config/containers/containers.conf`
+```toml
+[engine]
+image_default_format = "docker"
+```
+
+For just running the docker-compose.yml with docker image format:
+```bash
+BUILDAH_FORMAT=docker podman compose up --build
+```

+# WarpBox Security TO-DO
+
+## 1) High Priority (Do Next)
+
+- [ ] Persist IP bans across restarts
+  - Current: bans stored in-memory (`lib/security/guard.go`)
+  - Target: durable store in `DBDir` (similar style to `activity`/`alerts`)
+  - Include: startup load, expiry cleanup, atomic writes, corruption-safe fallback
+
+- [ ] Add trusted proxy CIDR config
+  - Current: forwarded headers trusted only when remote hop is private/local (`lib/server/ip.go`)
+  - Risk: heuristic-only trust model
+  - Target:
+    - `WARPBOX_TRUSTED_PROXY_CIDRS` setting
+    - trust `X-Forwarded-For` only when `RemoteAddr` in trusted CIDR
+    - fallback to direct remote IP otherwise
+
+- [ ] Add CIDR/range support for whitelists
+  - Current: exact IP match only (`WARPBOX_SECURITY_IP_WHITELIST`, `WARPBOX_SECURITY_ADMIN_IP_WHITELIST`)
+  - Target: support exact IP + CIDR entries
+  - Include strict parser + validation errors in settings save
+
+- [ ] Add unban / ban edit API audit trail hardening
+  - Ensure all manual ban/unban/ban-until actions always write:
+    - activity event
+    - alert (or policy-based selective alerting)
+  - Add tests for these paths
+
+## 2) Medium Priority
+
+- [ ] GeoIP integration for security detail pane
+  - Current: placeholder fields in `/admin/security`
+  - Target: wire geoipfast provider for country/region/ASN fields
+  - Add caching + timeout/failure-safe behavior
+
+- [ ] Expand malicious path detection rules
+  - Current: simple substring checks in `handleNoRoute`
+  - Target:
+    - rule list/pattern config
+    - normalize URL + decode checks
+    - classify severity by signature group
+
+- [ ] Add global abuse score per IP
+  - Combine signals:
+    - failed admin auth
+    - malicious path scans
+    - upload abuse
+  - Use score to escalate ban duration automatically
+
+- [ ] Ban duration policy ladder
+  - Current: fixed `WARPBOX_SECURITY_BAN_SECONDS`
+  - Target:
+    - progressive durations (e.g., 30m, 2h, 24h)
+    - reset after quiet period
+
+- [ ] Add security settings validation UX
+  - Ensure invalid values (negative, malformed lists, invalid CIDR) rejected with clear UI errors
+  - Add server tests for malformed security override payloads
+
+## 3) Admin UX Follow-Ups
+
+- [ ] Add dedicated “Active Bans” page-level controls
+  - bulk unban
+  - filter/sort by expiry and IP
+  - copy IP and quick search in activity/alerts
+
+- [ ] Add “why banned” detail
+  - link ban entry to latest triggering events and alerts
+  - show counts in active windows (login/scan/upload)
+
+- [ ] Add optional confirmation modal for destructive security actions
+  - unban all / bulk unban / long custom bans
+
+## 4) Testing & QA
+
+- [ ] Add unit tests for `lib/security/guard.go`
+  - `Ban`, `BanUntil`, `Unban`, `BanList` expiry pruning
+  - login/scan threshold behavior
+  - upload rate limiting behavior
+
+- [ ] Add tests for real-IP resolution edge cases (`lib/server/ip.go`)
+  - direct client
+  - trusted proxy chain
+  - spoofed forwarding headers from untrusted remote
+
+- [ ] Add integration tests for security endpoints
+  - `/admin/security/actions` ban/ban_until/unban
+  - `/admin/alerts/actions`
+  - admin login brute-force auto-ban flow
+
+- [ ] Add concurrency/race test pass in CI
+  - run `go test ./... -race` in workflow (where Go toolchain available)
+
+## 5) Operational / Deployment
+
+- [ ] Document reverse-proxy setup requirements
+  - Caddy / ingress config examples for forwarding headers
+  - guidance for trusted proxy CIDRs
+
+- [ ] Add security runbook
+  - how to investigate alerts
+  - how to ban/unban safely
+  - how to tune thresholds for low/high traffic environments
+
+- [ ] Add metrics hooks (future)
+  - counts: blocked requests, bans issued, unbans, alert volume
+  - expose to Prometheus-compatible endpoint later
+
+## 6) Nice-to-Have (Later)
+
+- [ ] Optional external enforcement bridge (fail2ban-compatible log format)
+- [ ] Webhook notifications for high-severity security alerts
+- [ ] Per-account/API-key limits once account system matures

+# GeoIP Guide (Planning)
+
+This project intentionally does not enable GeoIP enforcement yet.
+
+Planned integration target: `github.com/rabuchaim/geoip2fast`.
+
+## Recommended approach
+
+1. Load one shared GeoIP provider instance at startup.
+2. Add a small in-memory cache keyed by IP with TTL.
+3. Apply lookup timeout and fallback to `unknown` values on failures.
+4. Use results first in the admin security detail pane.
+5. Add aggregated statistics only after detail pane behavior is stable.
+
+## Why this is safe
+
+- No request path should fail because GeoIP lookup fails.
+- Lookup cost stays bounded with caching.
+- Security decisions remain independent from GeoIP quality.

+## Trusted Proxy Setup (Caddy)
+
+Set `WARPBOX_TRUSTED_PROXY_CIDRS` to only the CIDRs of your reverse proxies/load balancers.
+
+Example:
+
+```bash
+WARPBOX_TRUSTED_PROXY_CIDRS=10.0.0.0/8,192.168.0.0/16
+```
+
+Caddy example:
+
+```caddyfile
+:443 {
+  reverse_proxy 127.0.0.1:8080 {
+    header_up X-Forwarded-For {http.request.remote.host}
+    header_up X-Real-IP {http.request.remote.host}
+  }
+}
+```
+
+WarpBox will trust `X-Forwarded-For` only if the direct remote IP is inside `WARPBOX_TRUSTED_PROXY_CIDRS`.
+
+## IP Ban Operations
+
+- Use temporary bans by default.
+- Use `ban_until` only for active incidents requiring explicit windows.
+- Before unbanning, inspect related activity and alerts for repeated abuse patterns.
+- For destructive actions (`bulk_unban`, `unban_all`), require explicit confirmation.
+
+## Tuning Guidance
+
+- Low traffic deployments: reduce max-attempt thresholds to catch abuse faster.
+- High traffic deployments: increase windows and max-attempts incrementally to reduce false positives.
+- Watch for:
+  - repeated `auth.admin.failed`
+  - repeated `security.scan`
+  - frequent `security.upload_limit`
