Bryan Helmkamp b1bd2f522c feat(server): add variables API (#430) ... ## Summary Adds a workflow-visible variables store and HTTP API for managing non-sensitive run variables, then wires those variables into run config interpolation before run creation, validation, and preflight. ## What Changed - Adds `/api/v1/variables` CRUD endpoints backed by a JSON variable store and generated Rust/TypeScript API types. - Supports `{{ vars.NAME }}` interpolation alongside existing `{{ env.NAME }}` handling for run-owned config fields, including environment, MCP, hook, artifact, checkpoint, SCM, and notification settings. - Reuses canonical `fabro-types` variable DTOs in `fabro-api` and adds OpenAPI name patterns so clients see the same env-style variable contract enforced by the server. - Keeps variable updates store-owned with `update_existing`, avoiding duplicated not-found/update semantics in the HTTP handler. - Shares env-style name validation between variables, interpolation parsing, and vault token names to avoid grammar drift. Variables are intentionally non-sensitive: list/get responses include values, unlike vault secrets. ## Validation - `cargo +nightly-2026-04-14 fmt --check --all` - `cargo test -p fabro-types` - `cargo test -p fabro-variable` - `cargo test -p fabro-api --test variable_round_trip` - `cargo test -p fabro-server --features test-support --test it api::variables` - `cargo +nightly-2026-04-14 clippy -p fabro-types -p fabro-variable -p fabro-vault --all-targets -- -D warnings` - `cargo +nightly-2026-04-14 clippy -p fabro-server --features test-support --all-targets -- -D warnings` --- [](https://github.com/EveryInc/compound-engineering-plugin) 🤖 Generated with GPT-5 via [Codex](https://openai.com/codex/)		2026-05-27 11:46:36 -04:00
