# POST3-009: CI pipeline with Dagger Rust SDK

**Status:** Done
**Priority:** P1
**Blocked by:** —

## Description

Set up a Dagger-based CI pipeline using a custom self-contained `ci/` crate with `dagger-sdk` directly (not the external `cuddle-ci` / `dagger-rust` components, which are too opinionated for post3's context).

## What was built

- [x] `ci/` added as workspace member
- [x] `ci/Cargo.toml` with dependencies: dagger-sdk, eyre, tokio, clap
- [x] `ci/src/main.rs` — custom pipeline with:
  - `pr` and `main` subcommands (clap CLI)
  - Source loading with dependency caching (skeleton files pattern from dagger-components)
  - `rustlang/rust:nightly` base with clang + mold 2.3.3 for fast linking
  - Dagger cache volumes for target/ and cargo registry
  - `cargo check --workspace` compilation check
  - PostgreSQL 18 as Dagger service container for integration tests
  - `cargo test --workspace -- --test-threads=1` against Dagger PG
  - Release binary build + packaging into `debian:bookworm-slim`
  - `post3-server --help` sanity check in final image
- [x] `mise.toml` tasks: `ci:pr`, `ci:main`
- [x] No container publish (deferred until registry is decided)

## Reference

Pattern inspired by dagger-components (`/home/kjuulh/git/git.kjuulh.io/kjuulh/dagger-components`) but self-contained — no external git dependencies.
