Scott Werner a483402092 Interpolate run variables ({{ vars.* }}) in node prompts and goals (#524) ... ## What Threads the run's variable store through the workflow transform pipeline so node `prompt`s and the graph `goal` can interpolate `{{ vars.* }}`. Until now `{{ vars.* }}` only resolved in settings-level fields (e.g. `run.goal`) via the server-side `substitute_variables` pass. Node prompts are DOT graph attributes that pass never touched, so `{{ vars.* }}` in a prompt rendered as undefined. This closes that gap. Builds on the earlier template-context slice (adds `vars` to `TemplateContext`); this PR wires it end to end. ## How - `TransformOptions` carries a `vars` map, threaded into the import, file-inlining, and template transforms — and propagated into imported subgraphs, so imported prompts interpolate vars too. Every prompt/goal render context gains the variable map. - The create API accepts `vars` (`CreateRunInput` → `preprocess_and_validate` → `TransformOptions`). - The server snapshots its `VariableStore` at run creation (`VariableStore::value_map()`) and passes it in — the same store the settings-goal substitution already reads. ## Scope decisions - Goal `@file` contents interpolate vars too; **import paths stay inputs-only** (structural file resolution, conceptually outside the prompt/goal scope). - Offline / CLI / `fabro validate` render with an empty var map, so `{{ vars.* }}` is undefined there: a warning at validate, a hard error at run-create — identical to how `inputs` behaves offline. ## Testing - Transform-level: node-prompt and goal interpolation; unknown-var warning. - Create-pipeline: vars resolve; an unknown var warns at validate and promotes to a hard error at run-create. - End-to-end server test: `POST /variables` + `POST /runs`, asserting the rendered prompt in the persisted `run.created` event. Verified: `cargo +nightly fmt --check`, nightly `clippy -D warnings` (including the `test-support`-gated server integration binary), the tests above, and a full-workspace `cargo check`. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com>		2026-06-24 16:18:09 -04:00
