-## Runtime Flow
+1. Gitea sends a signed webhook to `POST /webhook/gitea`.
+2. The handler verifies the raw body, filters event/repository/bot policy, parses the command, deduplicates, and persists a job.
+3. The worker claims the oldest queued job and records a run attempt.
+4. Review/rerun jobs fetch PR metadata, enforce fork policy, read `.codex-review.yml` at the exact head SHA, and invoke the isolated runner.
+5. The runner checks out the exact head SHA, verifies `git rev-parse HEAD`, invokes Codex, and returns strictly validated JSON.
+6. The worker posts a new result/failure/acknowledgement comment and finalizes durable state.
 
-1. Gitea sends webhook to `POST /webhook/gitea`.
+## Compatibility guardrails
-2. Signature is validated (`X-Gitea-Signature`, sha256 HMAC).
-3. Non-supported events are ignored.
-4. PR context and command are extracted.
-5. Repo allowlist and dedupe checks run.
-6. Job is enqueued (`review_jobs`).
-7. Background worker claims queued jobs.
-8. For review/rerun:
-   - fetch PR context,
-   - run review in ephemeral container if possible,
-   - fallback to host execution on failure,
-   - post or edit persistent PR summary comment.
-9. Job/run status transitions are persisted.
 
-## Supported Commands
+- Preserve HMAC verification, allowlisting, bot self-comment filtering, and event/job dedupe.
+- Preserve response reasons and command behavior unless intentionally versioned.
+- Keep cooldown for `review`; `rerun` bypasses cooldown.
+- Allow two requeues after an initial failed attempt, then fail terminally.
+- Recover running jobs after the five-minute lease timeout.
+- Skip fork reviews by default.
+- Do not add host-side Codex fallback.
+- Keep posting new review comments while updating the `bot_comments` latest mapping; do not silently change to edit-in-place behavior.
+- Never mark infrastructure failure as a successful review.
+- Treat PR content, comments, `.codex-review.yml`, and model output as untrusted data.
 
-- `@codex review [security|performance|tests] [--full]`
+## Security-sensitive areas
-- `@codex rerun`
-- `@codex explain`
-- `@codex ignore`
 
-## Local Development
+- Do not log Gitea/OpenAI tokens, auth JSON, Docker arguments containing secrets, raw prompts, or unbounded provider output.
+- Do not pass Docker socket access into review containers.
+- Pin runner images and Codex versions for production.
+- Enforce body/output limits, context cancellation, container cleanup, and exact SHA verification.
+- Keep repository configuration from controlling credentials, images, host paths, commands, privileges, or network policy.
+- Review changes to `internal/runner`, `internal/webhook`, `internal/store/sqlstore`, and `internal/gitea` carefully.
 
-Install and run:
+## Development checks
+
+Before proposing a change:
 
 ```bash
-python -m pip install -e .[dev]
+gofmt -w cmd internal
-alembic upgrade head
+go test ./...
-uvicorn gitea_codex_bot.main:app --host 0.0.0.0 --port 8000
+go test -race ./...
+go vet ./...
+go build -trimpath ./cmd/gitea-codex
 ```
 
-Run tests:
+Changes affecting migrations, queue claims, or HTTP contracts require focused tests. MariaDB locking behavior must be verified separately from SQLite; SQLite tests do not prove `FOR UPDATE SKIP LOCKED` correctness.
-
-```bash
-pytest
-```
-
-Docker compose:
-> Locally only run this, is pre setup to use the dev compose file.
-```bash
-docker compose up --build -f docker-compose.dev.yml
-```
-
-## Environment Contract
-
-Required:
-
-- `GITEA_BASE_URL`
-- `GITEA_TOKEN`
-- `GITEA_BOT_USERNAME`
-- `GITEA_WEBHOOK_SECRET`
-- `ALLOWED_REPOS`
-- `DB_HOST`, `DB_PORT`, `DB_NAME`, `DB_USER`, `DB_PASSWORD`
-
-Common optional:
-
-- `DATABASE_URL` (overrides DB parts)
-- `OPENAI_API_KEY` (required when `CODEX_AUTH_MODE=api_key`)
-- `OPENAI_PROJECT_ID`, `OPENAI_ORG_ID`
-- `OPENAI_REVIEW_MODEL`
-- `CODEX_AUTH_MODE` (`api_key` default, `chatgpt` supported)
-- `CODEX_AUTH_JSON_PATH` (custom path to `auth.json` for `chatgpt` mode)
-- `WORKDIR`, `MAX_DIFF_BYTES`, `MAX_REVIEW_MINUTES`, `CONCURRENCY`
-- `REVIEW_RUNNER_IMAGE`
-- `ALLOW_UNTRUSTED_FORKS`
-
-## Database and Migrations
-
-- SQLAlchemy models are authoritative for runtime behavior.
-- Alembic migrations in `alembic/versions` must track schema changes.
-- If model schema changes, add a migration and keep migration tests passing.
-- CI runs `alembic upgrade head` before pytest.
-
-## Testing Expectations
-
-Before opening/merging changes:
-
-1. run `pytest`,
-2. if DB/model changes were made, ensure migration test still passes,
-3. for webhook/queue logic, add or update focused tests in `tests/`.
-
-Current tests rely on `tests/conftest.py` to inject default env and DB URL behavior.
-
-## Change Guardrails
-
-- Preserve webhook security checks and allowlist semantics.
-- Preserve dedupe constraints (`delivery_id`, `repo+comment_id`, `repo+trigger_comment_id`).
-- Keep bot self-comment ignore behavior.
-- Keep persistent comment update behavior (avoid comment spam regressions).
-- Be explicit when changing runner isolation/fallback behavior; this is a security-sensitive area.
-- Keep response payloads and command parsing backward compatible unless intentionally versioned.
-
-## Known Risks / Active Gaps
-
-See `TODO.md` for priority backlog, especially:
-
-- stronger isolated runner flow,
-- stricter host fallback controls,
-- end-to-end integration coverage.
-
-Treat these as high-sensitivity areas when modifying worker/runner paths.
-
-## Recommended Workflow for Agents
-
-1. Read touched service + corresponding tests first.
-2. Make minimal cohesive changes.
-3. Add/update tests with behavior changes.
-4. Run `pytest`.
-5. Summarize impact, risks, and follow-ups in PR/commit notes.
-
-## Commiting After Completion
-If you are confident that your changes are ready to be committed, please follow the commit message format below:
-
-```[type]. Short description (max 50 chars)```
-Push after commiting. Ask the user once if you have permission to commit and from then on commit without asking.

 # Gitea Codex Review Bot
 
-Webhook-driven PR review bot for Gitea.
+A self-hosted, webhook-driven pull-request review bot for Gitea, rebuilt in Go. It validates signed Gitea comment webhooks, queues durable review jobs, runs Codex in an isolated container at the exact PR head SHA, and posts structured feedback back to the pull request.
 
 ## Features
 
-- Handles `issue_comment` and `pull_request_comment` events.
+- HMAC-SHA256 verification of `X-Gitea-Signature` over the raw webhook body.
-- Verifies `X-Gitea-Signature` HMAC (`sha256`).
+- `issue_comment` and `pull_request_comment` support.
-- Triggers on `@codex ...`, `@<GITEA_BOT_USERNAME> ...`, plus optional custom aliases from `GITEA_BOT_MENTIONS`.
+- `@codex`, bot-username, and configured mention aliases.
-- Ignores bot-authored comments.
+- Bot-loop prevention and exact `ALLOWED_REPOS` enforcement.
-- Enforces strict repository allowlist (`ALLOWED_REPOS`).
+- Delivery/comment deduplication and PR review cooldowns.
-- Deduplicates webhook deliveries/comments in DB.
+- Durable FIFO jobs with retry and stale-running-job recovery.
-- Enforces PR cooldown for review requests.
+- MariaDB-compatible persistence with SQLite support for local tests.
-- Uses MariaDB + SQLAlchemy + Alembic.
+- `.codex-review.yml` at the exact PR head SHA.
-- Runs review jobs through ephemeral runner containers (with local fallback if Docker runtime is unavailable).
+- Fork review policy, disabled-repository acknowledgements, and non-review commands.
-- Posts/updates one persistent PR summary comment.
+- Strict structured review result validation and bounded Markdown comments.
-- Supports repository config via `.codex-review.yml`.
+- Isolated Docker runner with detached exact-SHA checkout verification.
+- Health and operational endpoints with bounded error output.
 
-## Endpoints
+The runner executes untrusted repository content. Secure the Docker API/socket, use least-privilege tokens, pin the runner image, restrict egress, and review the threat model before production use.
 
-- `POST /webhook/gitea`
+## Routes
-- `GET /healthz`
 
-## Webhook Setup Model
+- `GET /` — embedded service landing page.
+- `GET /healthz` — liveness response: `{"status":"ok"}`.
+- `GET /healthz/latest-job` — bounded latest-job metadata.
+- `GET /healthz/latest-failure` — bounded latest-failure metadata.
+- `POST /webhook/gitea` — signed Gitea webhook receiver.
 
-This bot is designed for self-hosted deployment:
+## Commands
 
-1. You host this service yourself.
+```text
-2. A Gitea admin points webhook events to your hosted endpoint:
+@codex review
-   - `https://your-bot-domain/webhook/gitea`
+@codex review security
-3. Gitea sends `issue_comment` and `pull_request_comment` events to that endpoint.
+@codex review performance --full
+@codex review tests
+@codex rerun
+@codex explain
+@codex ignore
+@codex help
+```
 
-Webhook configuration is manual by design.
+Commands must begin the comment. `@codex fix` is intentionally unsupported. Unknown prefixed commands receive an explanatory comment; ordinary comments without a command are ignored.
 
-Detailed setup instructions for both global and repository-only webhooks:
+## Configuration
 
-- [docs/webhook-setup.md](docs/webhook-setup.md)
+Copy `.env.example` to `.env`. Required values:
-
-## Environment
-
-Use `.env.example` as template.
-
-Required:
 
 - `GITEA_BASE_URL`
 - `GITEA_TOKEN`
 - `GITEA_BOT_USERNAME`
 - `GITEA_WEBHOOK_SECRET`
 - `ALLOWED_REPOS`
-- `DB_HOST`, `DB_PORT`, `DB_NAME`, `DB_USER`, `DB_PASSWORD`
+- `DATABASE_URL` or `DB_HOST`, `DB_PORT`, `DB_NAME`, `DB_USER`, `DB_PASSWORD`
+- `OPENAI_API_KEY` when `CODEX_AUTH_MODE=api_key`
 
-Optional:
+Important optional values include `OPENAI_REVIEW_MODEL`, `CODEX_AUTH_MODE`, `CODEX_AUTH_JSON_PATH`, `COOLDOWN_SECONDS`, `MAX_REVIEW_MINUTES`, `CONCURRENCY`, `REVIEW_RUNNER_IMAGE`, `ALLOW_UNTRUSTED_FORKS`, and `WEBHOOK_MAX_BYTES`.
 
-- `OPENAI_API_KEY` (required when `CODEX_AUTH_MODE=api_key`, optional when `CODEX_AUTH_MODE=chatgpt`)
+For local development, use SQLite:
-- `OPENAI_PROJECT_ID`
-- `OPENAI_ORG_ID`
-- `GITEA_BOT_MENTIONS` (comma-separated extra mention aliases, e.g. `@review-buddy,helper-bot`)
-- `CODEX_AUTH_MODE` (`api_key` default, or `chatgpt`)
-- `CODEX_AUTH_JSON_PATH` (custom host path to `auth.json`; defaults to `~/.codex/auth.json` in `chatgpt` mode)
-- `DATABASE_URL` (overrides composed DB URL)
 
-## Local Run
+```dotenv
+DATABASE_URL=sqlite://./gitea-codex.db
+```
+
+For production, use MariaDB and a scoped Gitea token. The Go service applies schema migrations on startup.
+
+## Local development
+
+Requirements: Go 1.25+, Docker for real review execution, and Gitea credentials for integration use.
 
 ```bash
-python -m pip install -e .[dev]
+go mod download
-alembic upgrade head
+go test ./...
-uvicorn gitea_codex_bot.main:app --host 0.0.0.0 --port 8000
+go vet ./...
+go build -trimpath -o gitea-codex ./cmd/gitea-codex
+
+# With environment configured:
+./gitea-codex
 ```
 
+The default listener is `:8000`; set `PORT` to change it. The unit/integration tests use a temporary SQLite database and fake Gitea HTTP server, so they do not require a live Gitea instance or Docker.
+
 ## Docker Compose
 
 ```bash
-# Local dev image build
+cp .env.example .env
+# Edit .env, then:
 docker compose -f docker-compose.dev.yml up --build
-
-# Published image
-docker compose up
 ```
 
-## CI
+The bot container needs access to the host Docker API to launch isolated review containers. Mounting `/var/run/docker.sock` is a privileged deployment decision; use a dedicated runner service or hardened Docker host where possible.
 
-The workflow in `.gitea/workflows/ci.yml`:
+## Repository configuration
 
-1. starts MariaDB service,
+A target repository may provide `.codex-review.yml`:
-2. runs Alembic migrations + tests,
-3. builds and pushes image tags to `gitea.reversed.dev/space/gitea-codex` on push.
 
-Expected secrets for publish job:
+```yaml
+enabled: true
+review:
+  default_mode: full
+  max_diff_bytes: 200000
+  include_tests: false
+  focus:
+    - correctness
+    - security
+    - maintainability
+ignore:
+  - generated/
+```
 
-- `REGISTRY_USERNAME`
+The file is read from the PR head and is treated as untrusted data. It cannot choose commands, credentials, images, host paths, container privileges, or network policy. Tests are disabled by default; `tests` mode or `include_tests: true` explicitly permits the runner to execute project tests.
-- `REGISTRY_PASSWORD`
 
-## AI Note
+## Webhooks and deployment
-This project is a super big experiment i made because i wanted to have codex reviews in gitea. I hate using Github and i will never willingly without good reasons use their copilot bs.
-This project was made WITH codex and is meant to be used WITH codex as a review agent.
-If you are as rich as Peter Steinberg and get a free OpenAI API Key, feel free to use it for this bot.
 
-## Contributing
+Webhook provisioning is manual in Gitea. See [docs/webhook-setup.md](docs/webhook-setup.md) for global and repository-only configuration. CI runs Go formatting, race-enabled tests, vet, and a static build before publishing an image.
-Contributions are welcome! Please open issues or submit pull requests for bug fixes, improvements, or new features.
+
+## Design notes
+
+This project exists to provide Codex-based review workflows for self-hosted Gitea installations without requiring GitHub. The implementation is intentionally provider- and runner-bound at the outer edge, while the domain, queue, storage, and HTTP layers remain independently testable.

+# Go rebuild notes
+
+The service was rebuilt from the product behavior rather than ported module-for-module from the previous Python implementation. The Go code keeps the durable table names and public webhook/health contracts while separating domain decisions from HTTP, SQL, Gitea, Docker, and Codex concerns.
+
+## Deliberate differences
+
+- There is no host-side review fallback. Runner failure is a failed attempt and is retried according to queue policy.
+- Review result output is validated strictly and bounded before persistence or posting.
+- The landing and 404 pages are embedded and do not load Tailwind from a third-party CDN.
+- The current tested append-comment behavior is retained: each completed review posts a new comment and updates the latest `bot_comments` mapping.
+- Docker execution is treated as a privileged deployment boundary. The bundled image runs the bot as root because direct Docker-socket access otherwise fails; production should replace this with a socket proxy or separate runner service, pinned images, resource limits, and least-privilege credentials.
+
+## Migration compatibility
+
+The Go startup migrator creates the logical `webhook_events`, `review_jobs`, `review_runs`, and `bot_comments` schema and preserves `trigger_comment_body`. Existing deployments should be backed up before switching binaries. The first Go release does not drop old columns or tables.

-# Webhook Setup (Global and Repository-Only)
+# Webhook setup
 
-This bot accepts Gitea webhook events at:
+The Go service accepts signed Gitea webhooks at:
 
 - `POST /webhook/gitea`
 
-It only processes these event types:
+It processes only `issue_comment` and `pull_request_comment` events. The handler verifies the exact raw request body with HMAC-SHA256 using `GITEA_WEBHOOK_SECRET`, enforces `ALLOWED_REPOS`, ignores bot-authored comments, and queues recognized `@codex` commands.
 
-- `issue_comment`
+## Configure Gitea
-- `pull_request_comment`
 
-It verifies `X-Gitea-Signature` using `GITEA_WEBHOOK_SECRET` (HMAC-SHA256).
+1. Deploy the service at a URL reachable by Gitea, for example `https://bot.example.com/webhook/gitea`.
+2. Set the same random secret in Gitea and `GITEA_WEBHOOK_SECRET`.
+3. Configure either an instance/global webhook or one repository webhook per target repository.
+4. Use JSON content type and enable only Issue comment and Pull request comment events.
+5. Add every allowed `owner/repository` to `ALLOWED_REPOS`.
+6. Test the webhook from Gitea, then check `GET /healthz`.
 
-## Prerequisites
+`WEBHOOK_MODE=global` or `WEBHOOK_MODE=repo` is a deployment label; webhook provisioning remains an administrator responsibility.
 
-1. Bot is reachable from Gitea (example: `https://bot.example.com/webhook/gitea`).
+## Environment
-2. `GITEA_WEBHOOK_SECRET` is set in your bot `.env`.
-3. `ALLOWED_REPOS` includes repositories you want to allow (example: `team/repo-a,team/repo-b`).
 
-## Option A: Global Webhook (single webhook, recommended)
+Required values are `GITEA_BASE_URL`, `GITEA_TOKEN`, `GITEA_BOT_USERNAME`, `GITEA_WEBHOOK_SECRET`, `ALLOWED_REPOS`, and either `DATABASE_URL` or the `DB_*` values. API-key Codex mode also requires `OPENAI_API_KEY`.
 
-Use this when you want one webhook configuration for many repositories.
+The recommended local development database is SQLite:
-
-1. In Gitea, open site administration webhook settings (instance-level/global webhooks).
-2. Add a new webhook of type `Gitea` (JSON payload).
-3. Set:
-   - `Payload URL`: `https://bot.example.com/webhook/gitea`
-   - `HTTP Method`: `POST`
-   - `Secret`: same value as `GITEA_WEBHOOK_SECRET`
-   - `Content Type`: `application/json`
-4. Enable only these events:
-   - `Issue comment`
-   - `Pull request comment`
-5. Save and use the webhook test/ping action.
-6. Set `WEBHOOK_MODE=global` in bot env (informational, for deployment clarity).
-
-Notes:
-
-- The bot still enforces `ALLOWED_REPOS`; non-allowlisted repos are ignored.
-- A global webhook is usually easiest to operate at scale.
-
-## Option B: Repository-Only Webhook (per repository)
-
-Use this when you want explicit repo-by-repo control.
-
-1. Open the repository in Gitea.
-2. Go to repository `Settings` -> `Webhooks`.
-3. Add a new `Gitea` webhook.
-4. Set:
-   - `Payload URL`: `https://bot.example.com/webhook/gitea`
-   - `HTTP Method`: `POST`
-   - `Secret`: same value as `GITEA_WEBHOOK_SECRET`
-   - `Content Type`: `application/json`
-5. Enable only:
-   - `Issue comment`
-   - `Pull request comment`
-6. Save and test.
-7. Repeat for each repository.
-8. Set `WEBHOOK_MODE=repo` in bot env.
-
-Important:
-
-- This bot has one configured secret (`GITEA_WEBHOOK_SECRET`) per bot instance.
-- If multiple repo webhooks use different secrets, signature verification will fail for repos not matching the configured secret.
-
-## Minimal `.env` snippet
 
 ```dotenv
-GITEA_WEBHOOK_SECRET=replace-with-random-secret
+DATABASE_URL=sqlite://./gitea-codex.db
-ALLOWED_REPOS=team/repo-a,team/repo-b
-WEBHOOK_MODE=global
 ```
 
-For repo-only mode, use `WEBHOOK_MODE=repo`.
+Production deployments should use MariaDB and a token with only the Gitea permissions needed to read pull requests/files and create comments. Keep the runner image pinned to a reviewed digest and treat review execution as untrusted code execution.
 
-## Validation Checklist
+## Command examples
 
-1. `GET /healthz` returns `{"status":"ok"}`.
+```text
-2. Webhook deliveries from Gitea return HTTP `200` (or bot returns accepted/ignored JSON, not `401`).
+@codex review
-3. `401 invalid signature` means webhook secret mismatch.
+@codex review security
-4. `{"accepted": false, "reason": "repo not allowed"}` means update `ALLOWED_REPOS`.
+@codex review performance --full
-5. A PR comment with `@codex review` on an allowlisted repo queues a job.
+@codex review tests
+@codex rerun
+@codex explain
+@codex ignore
+@codex help
+```
 
+Commands must begin the comment. Inline mentions in ordinary discussion text are intentionally ignored for compatibility. `@codex fix` is not supported.
+
+## Security notes
+
+- Invalid signatures return HTTP 401.
+- Fork pull requests are skipped unless `ALLOW_UNTRUSTED_FORKS=true`.
+- The bot launches review containers through the host Docker API; secure the Docker socket and runner host accordingly.
+- The review container receives credentials required by the configured Codex/Gitea workflow. Use least-privilege credentials, restrict network access, and do not use unpinned images in production.
+- Health detail endpoints expose bounded job metadata. Put them behind an internal network or reverse-proxy authentication if repository names and review errors are sensitive.
