-Remaining tasks sorted by priority for a working 1.0 release.
+pre-1.0. No git tags. Full policy file set is present, but make check
+fails on main with 10 gosec lint findings, so main is not green.
 
-## P0: Critical for 1.0
+# Next Step
 
-### Image Processing
-- [x] Add WebP encoding support (currently returns error)
-- [x] Add AVIF encoding support (implemented via govips)
+Fix the 10 gosec findings so make check passes on main. Fix each issue
+properly (no blanket nolint suppressions) and confirm lint, tests, and
+CI are green. This restores the main-always-green policy.
 
-### Manual Testing (verify auth/encrypted URLs work)
-- [ ] Manual test: visit `/`, see login form
-- [ ] Manual test: enter wrong key, see error
-- [ ] Manual test: enter correct signing key, see generator form
-- [ ] Manual test: generate encrypted URL, verify it works
-- [ ] Manual test: wait for expiration or use short TTL, verify expired URL returns 410
-- [ ] Manual test: logout, verify redirected to login
+# Completed Steps
 
-### Cache Management
-- [ ] Implement cache size management/eviction (prevent disk from filling up)
+- 2026-02-25: Docker arm64 build fixed via architecture detection for
+  golangci-lint download (#16)
+- 2026-02-25: full repo policy compliance pass (#14): LICENSE,
+  REPO_POLICIES.md, .editorconfig, Gitea Actions CI workflow, Docker
+  images pinned by hash, README restructured to policy sections, hooks
+  Makefile target, golangci-lint errors resolved
+- 2026-02-20: stale local dev config files removed (#12)
+- 2026-02-09: correctness fixes: negative cache checked in Service.Get()
+  before upstream fetch (#8); Stats() column scanning and HitRate
+  computation corrected (#9)
+- 2026-02-08: AllowHTTP propagated to SourceURL() scheme selection (#6)
+- WebP encoding support added (P0 item, checked off in TODO)
+- 2026-01-08: initial implementation with Makefile and TODO checklist

-## P1: Important for Production
+Compliance:
 
-### Security
-- [ ] Implement blocked networks configuration (extend SSRF protection)
-- [ ] Add rate limiting global concurrent fetches (prevent resource exhaustion)
+- After the gosec fix lands, verify CI runs make check green on main
 
-### Image Processing
-- [ ] Implement EXIF/metadata stripping (privacy)
+P0, critical for 1.0 (from existing TODO.md):
 
-## P2: Nice to Have
+- Add AVIF encoding support (currently returns error)
+- Manual test pass for auth and encrypted URLs:
+    - visit /, see login form
+    - wrong key shows error; correct signing key shows generator form
+    - generated encrypted URL works
+    - expired URL (short TTL) returns 410
+    - logout redirects to login
+- Implement cache size management and eviction (prevent disk fill)
+- Validate configuration on startup (fail fast on bad config)

-- [ ] Add rate limiting per-origin

-### HTTP Response Handling
-- [ ] Implement Last-Modified headers
-- [ ] Implement Vary header for content negotiation
-- [ ] Implement X-Request-ID propagation
+- Blocked networks configuration (extend SSRF protection)
+- Rate limit global concurrent fetches (resource exhaustion)
+- EXIF/metadata stripping (privacy)
 
-### Additional Endpoints
-- [ ] Implement auto-format selection (format=auto based on Accept header)
+P2, nice to have:
 
-### Configuration
-- [ ] Add all configuration options from README
-- [ ] Implement environment variable overrides
-- [ ] Implement YAML config file support
-
-### Operational
-- [ ] Implement Sentry error reporting (optional)
-- [ ] Add comprehensive request logging
-- [ ] Add performance metrics (Prometheus)
-- [ ] Write integration tests for image proxy flow
-- [ ] Write load tests to verify 1-5k req/s target
-
-### Documentation
-- [ ] Document configuration options
-- [ ] Document API endpoints
-- [ ] Document deployment guide
-- [ ] Add example nginx/caddy reverse proxy config
+- Referer blacklist; per-IP and per-origin rate limiting
+- Last-Modified headers; Vary header; X-Request-ID propagation
+- Auto-format selection (format=auto based on Accept header)
+- All configuration options from README; env var overrides; YAML config

-# Pixa Deployment via µPaaS
-
-Pixa is deployed on `fsn1app1` via
-[µPaaS](https://git.eeqj.de/sneak/upaas) (paas.datavi.be).
-
-## µPaaS App Configuration
-
-Create the app in the µPaaS web UI with these settings:
-
-| Setting | Value |
-| --- | --- |
-| **App name** | `pixa` |
-| **Repo URL** | `git@git.eeqj.de:sneak/pixa.git` |
-| **Branch** | `main` |
-| **Dockerfile path** | `Dockerfile` |
-
-### Environment Variables
-
-| Variable | Description | Required |
-| --- | --- | --- |
-| `PORT` | HTTP listen port (default: 8080) | No |
-
-Configuration is provided via the config file baked into the Docker
-image at `/etc/pixa/config.yml`. To override it, mount a custom
-config file as a volume (see below).
-
-### Volumes
-
-| Host Path | Container Path | Description |
-| --- | --- | --- |
-| `/srv/pixa/data` | `/var/lib/pixa` | SQLite database and image cache |
-| `/srv/pixa/config.yml` | `/etc/pixa/config.yml` | Production config (signing key, whitelist, etc.) |
-
-### Ports
-
-| Host Port | Container Port | Protocol |
-| --- | --- | --- |
-| (assigned) | 8080 | TCP |
-
-### Docker Network
-
-Attach to the shared reverse-proxy network if using Caddy/Traefik
-for TLS termination.
-
-## Production Configuration
-
-Copy `config.example.yml` from the repo root and customize for
-production:
-
-```yaml
-port: 8080
-debug: false
-maintenance_mode: false
-state_dir: /var/lib/pixa
-signing_key: "<generate with: openssl rand -base64 32>"
-whitelist_hosts:
-    - s3.sneak.cloud
-    - static.sneak.cloud
-    - sneak.berlin
-allow_http: false
-```
-
-**Important:** Generate a unique `signing_key` for production. Never
-use the default placeholder value.
-
-## Health Check
-
-The Dockerfile includes a `HEALTHCHECK` instruction that probes
-`/.well-known/healthcheck.json` every 30 seconds. µPaaS verifies
-container health 60 seconds after deployment.
-
-## Deployment Flow
-
-1. Push to `main` triggers the Gitea webhook
-2. µPaaS clones the repo and runs `docker build .`
-3. The Dockerfile runs `make check` (format, lint, test) during build
-4. On success, µPaaS stops the old container and starts the new one
-5. After 60 seconds, µPaaS checks container health
