+## Project Overview
+
+teabot is a Go daemon (systemd **user** service) that watches Gitea repositories
+and dispatches **one-shot Claude Code sessions in Docker containers** to work
+issues and review pull requests. It polls the Gitea API for new issues, pull
+requests, and comments; for each event it runs a throwaway container that clones
+the repo and runs `claude --print` with a task-specific prompt, acting as a
+configurable bot **personality**.
+
+## Structure
+

+## Build / test
+
+```bash

+make test       # go test -race ./...
+make rpm        # build + package RPM (needs nfpm)
+```
+
+Requires Go 1.25+. Deps: `github.com/spf13/cobra`, `gopkg.in/yaml.v3`.
+
+## Design notes for contributors
+
+- **Loop prevention is load-bearing.** Any event authored by a personality's
+  Gitea username is skipped (but recorded). Never remove this — it is what stops
+  the bot reacting to its own PRs/comments forever.
+- **Author allowlist is a security control.** Jobs run
+  `--dangerously-skip-permissions` with a prompt built from event text, so
+  teabot only dispatches for authors in `allowed_authors` (optional per-repo
+  override). Fail-closed: empty list dispatches nothing. Comment follow-ups gate
+  on the *new comment's* author, not just the acted-on thread. Skipped events are
+  marked processed-only (never acted-on).
+- **Dedup before dispatch.** Issues/PRs/comments are marked processed in the
+  state store *before* their job starts, so a re-poll or mid-job restart cannot
+  double-launch. State lives at `~/.local/state/teabot/state.json`.
+- **First-contact seeding.** The first poll of a repo records existing open
+  items as processed without dispatching, so a fresh install doesn't stampede.
+- **Follow-ups only on acted threads.** Comment follow-ups fire only when teabot
+  previously opened a PR for / reviewed the parent issue/PR.
+- **Docker is behind `docker.Runner`.** All dispatch logic is tested with a fake
+  runner; no Docker daemon is needed for `go test`. `DockerRunner.buildArgs` is
+  pure given a job dir so the `docker run` argument list is unit-tested directly.
+- **Personalities use tea configs.** tea persists to `$XDG_CONFIG_HOME/tea` and
+  has no `--config` flag, so each personality's config is mounted into the
+  container and `XDG_CONFIG_HOME` is set there.
+- **Image reuse.** The default `job_image` is `agent-dev`, which already ships
+  the claude CLI + dev toolchain; teabot does not build its own image.
+
+## Testing conventions
+
+Every package has meaningful unit tests (no rubber-stamps): config precedence &
+validation & tea parsing, state persistence/dedup roundtrips, gitea client via
+`httptest`, prompt content assertions, docker arg/mount/env construction, and
+dispatch filtering/loop-prevention/seeding/follow-up routing via a fake client +
+fake runner. `go build ./...` and `go test -race ./...` must pass.
+
+## Conventions (house rules)
+
+- Branches `benvin/<name>`. PR bodies: short "why" paragraph + present-tense
+  "how" bullets. HTTPS remotes for git.unkin.net (SSH blocked). Use `tea`, not
+  `gh`. Do not merge PRs yourself.
+- Releases are Woodpecker pipelines triggered on `v*` tags; bump with
+  `make patch|minor|major`. Every CI step sets k8s resource requests+limits.

 # teabot
 
-A Go daemon that watches Gitea repos and dispatches one-shot Claude Code sessions in Docker to work issues and review PRs.
+teabot is a Go daemon (shipped as a systemd **user** service) that watches Gitea
+repositories and dispatches **one-shot Claude Code sessions in Docker containers**
+to work issues and review pull requests.
+
+On each poll it looks for new issues, new pull requests, and new comments across
+the repos it watches. For each event it launches a throwaway container that
+clones the repo fresh and runs `claude --print` with a task-specific prompt:
+
+- **New issue** → an *implementer* personality reviews it and, if it warrants a
+  change, opens a PR that closes the issue (following the house PR conventions).
+- **New pull request** → a *reviewer* personality critiques the diff and posts an
+  approving or change-requesting review.
+- **New comment** on a thread teabot already engaged with → a follow-up session
+  responds or makes the requested change.
+
+Each personality is a distinct Gitea bot account backed by its own `tea` config
+file, so an implementer bot can open PRs that a separate reviewer bot critiques.
+teabot never reacts to events authored by its own personalities (loop
+prevention) and persists processed state so restarts don't re-trigger work.
+
+**Security:** sessions run `claude --dangerously-skip-permissions` with a prompt
+built from event text, so teabot only acts on events from authors on a
+configured `allowed_authors` allowlist (fail-closed — an empty list dispatches
+nothing). See [Author allowlist](docs/configuration.md#author-allowlist-security).
+
+## Quick start
+
+```bash
+# 1. Create the config and edit it.
+teabot config init
+$EDITOR ~/.config/teabot/config.yaml
+
+# 2. Create a tea login file per personality (a normal tea config.yml).
+tea logins add --name teabot-impl   --url https://git.unkin.net --token <impl-token>
+tea logins add --name teabot-review --url https://git.unkin.net --token <review-token>
+# point each personality's tea_config: at the resulting config.yml
+
+# 3. Validate, then run a single cycle to test.
+teabot config show
+teabot run --once
+
+# 4. Enable the daemon.
+systemctl --user enable --now teabot
+```
+
+## Documentation
+
+- [Architecture](docs/architecture.md) — how polling, dispatch, and the Docker
+  execution model fit together.
+- [Configuration](docs/configuration.md) — every config key, personalities, and
+  Claude/tea credential handling.
+- [`teabot run`](docs/run.md) — running the daemon, `--once`, logging, systemd.
+- [`teabot config`](docs/config.md) — the `init` and `show` subcommands.
+
+## Build
+
+```bash
+make build      # -> dist/teabot (static, CGO disabled)
+make test       # go test -race ./...
+make rpm        # build + package an RPM (needs nfpm)
+```
+
+Requires Go 1.25+. A `v*` tag triggers the release pipeline: a Gitea release
+with cross-platform binaries plus an RPM published to the artifactapi
+`rpm-internal` repo.

+# Architecture
+
+teabot is a single binary with a small set of internal packages. The daemon
+polls Gitea, decides which events warrant work, and runs each unit of work as a
+disposable Docker container.
+
+```

+  └── internal/cli        cobra command tree (run, config)

+```
+
+## Poll cycle
+
+`dispatch.Dispatcher` runs one `pollRepo` per watched repo each interval:
+
+1. **List** open issues, open pull requests, and recent comments via the Gitea
+   API (one client authenticated as the first personality — reads only).
+2. **Seed on first contact.** The very first poll of a repo records everything
+   currently open/recent as *processed* without dispatching anything, so a fresh
+   install does not stampede every existing item. The `seeded` flag is persisted
+   per repo.
+3. **Classify & dispatch** subsequent events:
+   - a new issue → implementer session,
+   - a new pull request → reviewer session,
+   - a new comment on a thread teabot **acted on** → follow-up session.
+
+## Filtering rules (loop prevention + dedup)
+
+Three independent guards decide whether an event becomes a job:
+
+- **Loop prevention** — any event authored by one of teabot's own personality
+  logins is skipped. This is what stops the bot reacting to its own PRs and
+  comments in an infinite loop. Bot-authored items are still *recorded* as
+  processed so they are never reconsidered.
+- **Author allowlist (security)** — because jobs run
+  `--dangerously-skip-permissions` with a prompt built from event text, teabot
+  dispatches only for events whose author is on the `allowed_authors` list
+  (with an optional per-repo override). This is **fail-closed**: an empty
+  allowlist dispatches nothing. Non-allowlisted events are recorded (never
+  re-triggered) and logged, but never spawn a container. Comment follow-ups are
+  gated on the *new comment's* author, so an untrusted comment on a bot thread
+  cannot reopen the injection path. See
+  [configuration](configuration.md#author-allowlist-security).
+- **Dedup** — every dispatched issue/PR index and every seen comment ID is
+  recorded in the state store (`~/.local/state/teabot/state.json`). An item is
+  marked processed *before* its job starts, so a subsequent poll (or a restart
+  mid-job) cannot double-launch it.
+
+Comment follow-ups additionally require the parent issue/PR to be in the
+*acted-on* set — teabot only continues threads it started, never arbitrary
+comment threads. See [configuration](configuration.md) for the implication.
+
+## Job execution
+
+Each session is a `docker.Job` handed to a `docker.Runner`. The production
+`DockerRunner`:
+
+1. Materialises a per-job scratch dir containing the prompt, a static
+   `job.sh` entrypoint, a **private copy** of the Claude config dir (so
+   subscription-token refreshes never mutate the host's `~/.claude`), and a copy
+   of the personality's tea config.
+2. Runs `docker run --rm --entrypoint /bin/bash <image> /teabot/job.sh` with:
+   - the scratch files bind-mounted (`:ro,z` under SELinux),
+   - the tea config mounted at `$HOME/.config/tea/config.yml` and
+     `XDG_CONFIG_HOME` set, so `tea` acts as the bot identity,
+   - git identity + a credential-store token so clones and pushes authenticate,
+   - `ANTHROPIC_API_KEY` / `ANTHROPIC_BASE_URL` injected only when configured
+     (otherwise the mounted subscription credentials are used).
+3. `job.sh` configures git, clones the repo, and runs
+   `claude --print --dangerously-skip-permissions < /teabot/prompt.txt`.
+
+The `Runner` interface means the whole dispatch layer is unit-testable with a
+fake runner — no Docker daemon required. Concurrency is bounded by a semaphore
+sized to `max_concurrent`, and every job has a `job_timeout`.
+
+## Container image
+
+teabot reuses the existing **`git.unkin.net/unkin/agent-dev:latest`** image,
+which already bundles the `claude` CLI plus a Go/Node/Python/`tea` developer
+toolchain and language servers. The image is configurable via `job_image`, so a
+purpose-built image can be substituted without code changes.

+Inspect and scaffold teabot configuration.
+
+## `teabot config init`
+
+Writes a fully-commented example config to the `--config` path (default
+`~/.config/teabot/config.yaml`).
+
+```bash
+teabot config init            # writes ~/.config/teabot/config.yaml
+teabot config init --force    # overwrite an existing file
+teabot config init -c ./my.yaml
+```
+
+It refuses to overwrite an existing file unless `--force` is given. After
+writing, edit the file and create the tea config files each personality
+references (see [configuration](configuration.md)).
+
+## `teabot config show`
+
+Loads, validates, and prints the effective configuration — defaults applied and
+each personality resolved from its tea config (username shown, token never
+printed). A validation error here means `teabot run` would fail too, so this is
+the quickest pre-flight check.

+
+| Key | Default | Description |
+|-----|---------|-------------|

+| `repos` | *(required)* | List of `owner/name` repositories to watch. |
+| `poll_interval` | `60s` | Delay between poll cycles (Go duration). |
+| `max_concurrent` | `2` | Maximum job containers running at once. |
+| `job_timeout` | `30m` | Per-session wall-clock timeout. |
+| `job_image` | `git.unkin.net/unkin/agent-dev:latest` | Container image each session runs in. |
+| `container_home` | `/home/agent` | Home dir inside `job_image` (mount target). |
+| `claude_config_dir` | `~/.claude` | Host dir with Claude Code credentials. |
+| `anthropic_api_key` | *(unset)* | If set, injected as `ANTHROPIC_API_KEY`. |
+| `anthropic_base_url` | *(unset)* | If set, injected as `ANTHROPIC_BASE_URL`. |
+| `state_dir` | `~/.local/state/teabot` | Where processed-event state is persisted. |
+| `allowed_authors` | *(empty → fail-closed)* | Gitea usernames whose events may trigger a job. See [Author allowlist](#author-allowlist-security). |
+| `repo_allowed_authors` | *(unset)* | Optional per-repo override of `allowed_authors`, keyed by `owner/name`. |
+| `personalities` | *(required)* | Bot identities (see below). |
+
+`~` and `~/` are expanded in path-valued keys.
+
+## Personalities
+
+A personality is a distinct Gitea bot account. teabot must be able to act as
+different identities — e.g. an implementer that opens PRs and a separate reviewer
+that critiques them — so each personality points at its **own tea config file**
+rather than sharing your personal `~/.config/tea/config.yml`.
+
+```yaml
+personalities:
+  - name: implementer
+    tea_config: ~/.config/teabot/tea-implementer.yml
+    role: implementer          # implementer | reviewer | both
+    git_name: Teabot Implementer
+    git_email: teabot-implementer@unkin.net
+  - name: reviewer
+    tea_config: ~/.config/teabot/tea-reviewer.yml
+    role: reviewer
+    git_name: Teabot Reviewer
+    git_email: teabot-reviewer@unkin.net
+```
+
+| Field | Description |
+|-------|-------------|
+| `name` | Label used in logs and prompts. |
+| `tea_config` | Path to a `tea` config.yml holding this bot's login. teabot reads the API token + username from it and mounts it into the job container. |
+| `role` | `implementer` (issues), `reviewer` (pull requests), or `both`. Defaults to `both`. |
+| `git_name` / `git_email` | Commit identity set inside the container. |
+
+Create each tea config with the normal tea workflow, pointing `HOME`/
+`XDG_CONFIG_HOME` at a scratch dir so it lands somewhere dedicated, or copy an
+existing `config.yml` and edit the token. The file format is exactly tea's own:
+
+```yaml
+logins:
+  - name: teabot-implementer
+    url: https://git.unkin.net
+    token: <bot-api-token>
+    default: true
+    user: teabot-implementer
+```
+
+teabot picks the login whose `url` matches `gitea_url`, else the `default`, else
+the first. The `user` field is the bot's username — teabot uses it for **loop
+prevention** (it never reacts to events authored by any personality's username).
+
+At least one personality must be able to implement and at least one to review,
+or config validation fails.
+
+## Author allowlist (security)
+
+Each job runs `claude --print --dangerously-skip-permissions` inside a container,
+and its **prompt is built from event text** — the issue title/body, PR
+description/diff, and comments. That text is attacker-controllable: anyone who
+can open an issue or comment on the repo could otherwise inject instructions
+into a session that has permissions disabled. The allowlist is the control that
+closes this: teabot dispatches a job **only** when the triggering event's author
+login is on the allowlist.
+
+```yaml
+# Global allowlist.
+allowed_authors:
+  - benvin
+  - trusted-colleague
+
+# Optional per-repo override. A present entry fully REPLACES the global list for
+# that repo; an empty list disables dispatch for it; an absent entry falls back
+# to the global list.
+repo_allowed_authors:
+  unkin/teabot:
+    - benvin
+```
+
+Semantics:
+
+- **Fail-closed.** An empty/absent allowlist dispatches **nothing**. teabot logs
+  a warning at startup when no allowlist is configured anywhere.
+- Events from non-allowlisted authors are **recorded** as processed (so they
+  don't re-trigger) and logged at info with the author name, but never spawn a
+  container. They are *not* marked as engaged threads.
+- **Comment follow-ups are gated on the new comment's author**, not just the
+  thread. A comment from a non-allowlisted user on a thread teabot previously
+  acted on is ignored — otherwise an untrusted comment could reopen the
+  injection path on a bot thread.
+- Matching is case-insensitive (Gitea usernames are unique case-insensitively).
+- This is **separate from and in addition to** loop prevention: bot personality
+  logins are always excluded first, even if one were listed here.
+
+## Claude credentials
+
+By default teabot uses your Claude **subscription** auth: it copies
+`claude_config_dir` (default `~/.claude`) into a per-job scratch dir and mounts
+that copy read-write into the container, so the session can refresh tokens
+without ever mutating your real config.
+
+Alternatively set `anthropic_api_key` (and optionally `anthropic_base_url` for a
+gateway such as LiteLLM). When present these are injected as environment
+variables and take precedence over the mounted subscription credentials.
+
+## SELinux
+
+This host is Fedora, so Docker bind mounts are relabelled with `:z`. teabot does
+this automatically. If you run under a different security model, the relabel
+suffix is a field on `DockerRunner` (`SELinuxLabel`).
+
+## A note on comment follow-ups
+
+teabot only continues comment threads on issues/PRs it **acted on** itself
+(opened a PR for, or reviewed). A comment on an unrelated thread is recorded but
+ignored. Combined with loop prevention (bot-authored comments are skipped), this
+means teabot will not, for example, keep answering an issue it decided not to
+implement — it engages a thread only after it has taken an action there.

+# `teabot run`
+
+Runs the daemon in the foreground. It polls the configured repos on `poll_interval`
+and dispatches Claude sessions. This is the command the systemd user unit executes.
+
+```bash
+teabot run [flags]
+```
+
+## Flags
+
+| Flag | Default | Description |
+|------|---------|-------------|
+| `--once` | `false` | Run a single poll cycle then exit. Blocks until every job dispatched during the cycle finishes — ideal for testing. |
+| `--log-json` | `false` | Emit structured JSON logs instead of text. |
+| `--log-level` | `info` | `debug`, `info`, `warn`, or `error`. |
+| `-c`, `--config` | `~/.config/teabot/config.yaml` | Config file path (inherited from the root command). |
+
+Logs go to stderr (captured by the systemd journal). teabot handles `SIGINT`/
+`SIGTERM` by stopping the poll loop and waiting for in-flight jobs to finish
+before exiting.
+
+## Examples
+
+```bash
+# One cycle, verbose, to see what would be dispatched.
+teabot run --once --log-level debug
+
+# Foreground daemon with JSON logs.
+teabot run --log-json
+```
+
+## systemd (user service)
+
+The RPM installs a user unit at `/usr/lib/systemd/user/teabot.service`.
+
+```bash
+systemctl --user daemon-reload
+systemctl --user enable --now teabot
+journalctl --user -u teabot -f
+```
+
+Because it is a **user** service it runs as your login user, so it inherits your
+Docker access and your `~/.claude` credentials. To keep it running when you are
+not logged in, enable lingering:
+
+```bash
+loginctl enable-linger "$USER"
+```
+
+## Requirements at runtime
+
+- `docker` on `PATH` and usable by the running user.
+- The configured `job_image` pullable from the registry.
+- Each personality's tea config file present and readable.
+- Claude credentials available (subscription `~/.claude` or an
+  `anthropic_api_key` in the config).
