A release-readiness QA pass over the whole product. The commits split into defects a user would hit and gates that were reporting green while measuring nothing. ## Fixes that change behaviour Rate limiting was bypassable on every install: TRUST_PROXY defaulted to true, so request.ip came from a client-set header and a forged X-Forwarded-For got past the login limiter. The default is now a private-network trust list. A transient Postgres outage stranded in-flight jobs, leaving finished output on disk with no row pointing at it. A reconciler now resolves those rows and adopts the bytes rather than dropping the work. A Redis connection that moved to a new address wedged every read-blocked consumer, so completions stopped signalling while health still answered 200. Socket timeouts plus subscriber pings recover it. Installing more than one AI bundle left the shared venv multi-versioned and silently broke three tools. The installer now reconciles distributions to one version each. Converting an image to JXL at quality 1 through 4 returned a 500, because libjxl 0.7 rejects the distance those values compute. The quality is floored at what the encoder honours. A missing ffmpeg was also reported to the user as a corrupt upload; it now says the engine is unavailable. RAW uploads reached an unpatched LibRaw on arm64, so it is built from source at 0.22.2, and the release scan was split so it can fail on an unfixed critical instead of hiding it behind ignore-unfixed. ## Gates that could not fail Two mutation lanes ran zero mutants because Stryker crawled the gitignored docs build; coverage discarded its whole report on any failing test; the lint gate skipped root tests, scripts, and two workspaces; and several generated matrices counted a host missing ffmpeg as a passing tool. Each now measures what it claims. Full evidence and the outstanding release items are tracked locally and are not part of this branch.

What We Will Not Accept
- Changes to CI/CD workflows, release config, or linter/compiler config
- PRs without a signed Contributor License Agreement

Development Setup
Prerequisites
- Node.js 22.22+
- pnpm 9+
- Python 3.11+ (only for AI tools)
- Docker (optional, for full integration testing)
Getting Started
# Fork and clone
git clone https://github.com/<your-username>/snapotter.git
cd snapotter
# Install dependencies
pnpm install
# Start dev servers (web on :1351, API on :13490)
pnpm dev
Running Checks
Before submitting a PR, ensure all checks pass locally:
pnpm lint # Biome lint + format check
pnpm typecheck # TypeScript across monorepo
pnpm test # Vitest unit + integration tests
To run a single test file:
pnpm vitest run tests/unit/my-test.test.ts
pnpm vitest run tests/integration/my-test.test.ts
Code Style
- Biome handles formatting and linting (double quotes, semicolons, 2-space indent)
- Pre-commit hook runs
biome check --writeon staged files automatically - If the linter complains, fix the code (do not modify Biome config)
- ES modules everywhere (
import/export,.jsextensions on relative imports) - Conventional commits:
feat:,fix:,refactor:,docs:,test:,chore:
Architecture Quick Reference
A tool lives in three places sharing a toolId string:
- Shared metadata -
packages/shared/src/constants.ts(TOOLS array) - API route -
apps/api/src/routes/tools/<toolId>.ts(usescreateToolRoutefactory) - Frontend settings -
apps/web/src/components/tools/<toolId>-settings.tsx
For full architecture details, see the Developer Guide.
Pull Request Process
- Fork the repo and create a branch from
main(feat/my-featureorfix/issue-123) - Make your changes in focused, reviewable commits using conventional commits
- Add or update tests for your changes
- Run
pnpm lint && pnpm typecheck && pnpm testlocally - Open a PR against
mainand fill out the template - Sign the CLA if prompted
- Wait for CI to pass and a maintainer to review
Review Expectations
- We aim to respond to PRs within 7 days
- Small, focused PRs get reviewed faster
- If you have not heard back in 7 days, leave a comment pinging the thread
- We may request changes, suggest a different approach, or close the PR if it does not align with project direction
After Your PR is Merged
Your contribution will be included in the next release and credited in the changelog.
