+Goal: # Automations Backend API Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Build the backend data model and REST API for creating, editing, deleting, starting, and listing runs for Automations.
+
+**Architecture:** Automations are server-owned runnable bindings stored as one canonical TOML file per automation in `dirname(active_config_path)/automations/<id>.toml`. The server loads those files into an in-memory store at startup, persists API mutations atomically, and attaches an automation reference to runs created through the automation API. Schedule triggers are stored and validated, but no cron scheduler or background trigger loop is added in this plan.
+
+**Tech Stack:** Rust, serde, toml, toml_edit, sha2, hex, croner for schedule validation only, Axum, OpenAPI/progenitor, existing Fabro run manifest and run creation pipeline.
+
+---
+
+## Locked Decisions
+
+- Backend only: do not add web UI routes/components and do not add CLI commands.
+- Storage root: `dirname(active_config_path)/automations`.
+- File layout: one automation per file, `automations/<id>.toml`.
+- Canonical ID: the filename stem. The TOML file does not repeat `id`.
+- Automation ID format: `[a-z0-9][a-z0-9-]{0,62}`.
+- Trigger ID format: `[a-z0-9][a-z0-9_-]{0,62}`.
+- Trigger IDs are required, user-visible, editable, and unique within one automation.
+- Triggers are an array from v1.
+- The API trigger type is `api`, not `manual_api`. Trigger IDs remain user-visible and editable; examples use `id = "api"` but startability is based on `type = "api"`.
+- At most one trigger with `type = "api"` is allowed per automation.
+- Multiple `schedule` triggers are allowed.
+- Unknown trigger types, including future `event` shapes, return `422` in v1. Handlers must not let unknown trigger discriminators fail as JSON parse errors.
+- If an automation is disabled, or it has no enabled trigger with `type = "api"`, `POST /automations/{id}/runs` returns `409` and does not create a run.
+- API writes canonicalize TOML and may discard comments in automation files.
+- No runtime automation state store or derived automation status API is added in V1. Run history is available through `GET /automations/{id}/runs`; schedule expressions are validated but not evaluated for scheduling.
+

+
+## Public API Shape
+
+Add these OpenAPI paths under `/api/v1`:
+
+```http
+GET    /automations
+POST   /automations
+GET    /automations/{id}
+PUT    /automations/{id}
+PATCH  /automations/{id}
+DELETE /automations/{id}
+GET    /automations/{id}/runs
+POST   /automations/{id}/runs
+```
+
+Use this response model:
+
+```ts
+type Automation = {
+  id: string;
+  revision: string;
+  name: string;
+  description: string | null;
+  enabled: boolean;
+  target: AutomationTarget;
+  triggers: AutomationTrigger[];
+};
+
+type AutomationTarget = {
+  repository: string; // GitHub owner/repo
+  ref: string;
+  workflow: string;
+};
+
+type AutomationTrigger =
+  | { id: string; type: "api"; enabled: boolean }
+  | { id: string; type: "schedule"; enabled: boolean; expression: string };
+
+```
+
+Request models:
+
+```ts
+type CreateAutomationRequest = {
+  id: string;
+  name: string;
+  description?: string | null;
+  enabled?: boolean;
+  target: AutomationTarget;
+  triggers: AutomationTrigger[];
+};
+
+type ReplaceAutomationRequest = {
+  name: string;
+  description?: string | null;
+  enabled: boolean;
+  target: AutomationTarget;
+  triggers: AutomationTrigger[];
+};
+
+type PatchAutomationRequest = {
+  name?: string;
+  description?: string | null;
+  enabled?: boolean;
+  target?: AutomationTarget;
+  triggers?: AutomationTrigger[];
+};
+```
+
+`GET /automations/{id}/runs` returns the existing paginated run list envelope:
+
+```json
+{
+  "data": [],
+  "meta": { "has_more": false, "total": 0 }
+}
+```
+
+It accepts `page[limit]` and `page[offset]`, sorts newest first, filters by `Run.automation.id`, and returns `404` if the automation definition no longer exists.
+
+`POST /automations/{id}/runs` returns the existing `Run` response shape with `automation` populated:
+
+```json
+{
+  "automation": {
+    "id": "nightly-deps",
+    "name": "Nightly dependency update",
+    "trigger_id": "api"
+  }
+}
+```
+
+## TOML Shape
+
+Persist this canonical TOML:
+
+```toml
+name = "Nightly dependency update"
+description = "Open a PR for dependency updates."
+enabled = true
+
+[target]
+repository = "fabro-sh/fabro"
+ref = "main"
+workflow = "dependency-update"
+
+[[triggers]]
+id = "api"
+type = "api"
+enabled = false
+
+[[triggers]]
+id = "nightly"
+type = "schedule"
+enabled = true
+expression = "0 3 * * *"
+```
+
+Defaults:
+
+- `enabled` defaults to `true` when omitted in TOML or create requests.
+- `description` defaults to `null`.
+- Trigger `enabled` defaults to `true` when omitted in TOML or create requests.
+- `schedule.expression` must be a non-empty five-field cron expression accepted by `croner`.
+- `target.repository` must be a GitHub `owner/repo` slug using the existing server slug validation rules: owner max 39 chars, repo max 100 chars, no path traversal or separators inside either segment.
+- `target.ref` must be a non-empty branch, tag, or SHA selector and must not start with `-`, contain ASCII control characters, or contain shell/path traversal metacharacters that would make git argv ambiguous.
+- `target.workflow` is a Fabro workflow selector resolved inside the cloned repository with `WorkflowLocation::resolve`; it may be a workflow slug such as `dependency-update` or a relative workflow path, but absolute paths and `..` path traversal are invalid.
+
+## Task 1: Add Domain Crate And Model Tests
+
+**Files:**
+
+- Create: `lib/crates/fabro-automation/Cargo.toml`
+- Create: `lib/crates/fabro-automation/src/lib.rs`
+- Create: `lib/crates/fabro-automation/src/error.rs`
+- Create: `lib/crates/fabro-automation/src/id.rs`
+- Create: `lib/crates/fabro-automation/src/model.rs`
+
+- [ ] Read `docs/internal/testing-strategy.md` and `docs/internal/error-handling-strategy.md` before adding tests and error types.
+- [ ] Create the crate. Because the workspace uses `members = ["lib/crates/*"]`, no root workspace member edit is required.
+- [ ] Add dependencies in `lib/crates/fabro-automation/Cargo.toml`: `chrono`, `croner`, `hex`, `serde`, `sha2`, `thiserror`, `tokio`, `toml`, and `toml_edit`. Add dev-dependencies: `tempfile`.
+- [ ] Define `AutomationId` and `AutomationTriggerId` newtypes with `TryFrom<String>`, `AsRef<str>`, `Display`, `Serialize`, and `Deserialize`.
+- [ ] Define the domain model with this public shape:
+
+```rust
+pub struct AutomationRevision(String);
+
+pub struct RepositorySlug(String);
+
+pub struct GitRefSelector(String);
+
+pub struct WorkflowSlug(String);
+
+pub struct Automation {
+    pub id: AutomationId,
+    pub revision: AutomationRevision,
+    pub name: String,
+    pub description: Option<String>,
+    pub enabled: bool,
+    pub target: AutomationTarget,
+    pub triggers: Vec<AutomationTrigger>,
+}
+
+pub struct AutomationTarget {
+    pub repository: RepositorySlug,
+    pub ref_: GitRefSelector,
+    pub workflow: WorkflowSlug,
+}
+
+#[serde(tag = "type", rename_all = "snake_case")]
+pub enum AutomationTrigger {
+    Api(ApiTrigger),
+    Schedule(ScheduleTrigger),
+}
+
+pub struct ApiTrigger {
+    pub id: AutomationTriggerId,
+    pub enabled: bool,
+}
+
+pub struct ScheduleTrigger {
+    pub id: AutomationTriggerId,
+    pub enabled: bool,
+    pub expression: String,
+}
+
+pub struct AutomationDraft {
+    pub id: AutomationId,
+    pub name: String,
+    pub description: Option<String>,
+    pub enabled: Option<bool>,
+    pub target: AutomationTarget,
+    pub triggers: Vec<AutomationTrigger>,
+}
+
+pub struct AutomationReplace {
+    pub name: String,
+    pub description: Option<String>,
+    pub enabled: bool,
+    pub target: AutomationTarget,
+    pub triggers: Vec<AutomationTrigger>,
+}
+
+pub struct AutomationPatch {
+    pub name: Option<String>,
+    pub description: Option<Option<String>>,
+    pub enabled: Option<bool>,
+    pub target: Option<AutomationTarget>,
+    pub triggers: Option<Vec<AutomationTrigger>>,
+}
+```
+
+- [ ] Use `#[serde(rename = "ref")]` for the Rust field `ref_`.
+- [ ] Keep `revision` out of the persisted TOML model; compute it from raw file bytes.
+- [ ] Reject empty names, invalid GitHub repository slugs, invalid refs, invalid workflow selectors, duplicate trigger IDs, and more than one trigger with `type = "api"`.
+- [ ] Add unit tests for valid TOML, defaults, invalid automation IDs, invalid trigger IDs, duplicate trigger IDs, two `api` triggers, invalid repository slug, and invalid schedule expression.
+- [ ] Run `cargo nextest run -p fabro-automation`.
+- [ ] Commit:
+
+```bash
+git add lib/crates/fabro-automation
+git commit -m "feat: add automation domain model"
+```
+
+## Task 2: Implement File-Backed Automation Store
+
+**Files:**
+
+- Create: `lib/crates/fabro-automation/src/store.rs`
+- Modify: `lib/crates/fabro-automation/src/lib.rs`
+
+- [ ] Implement `AutomationStore` as an in-memory map guarded by `tokio::sync::RwLock`.
+- [ ] Load files from a configured directory with this behavior:
+  - Missing directory means an empty store.
+  - Non-`.toml` files are ignored.
+  - Invalid filenames fail load.
+  - Invalid TOML or invalid automation data fails load.
+- [ ] Compute `AutomationRevision` as lowercase hex SHA-256 of the exact TOML bytes read from disk.
+- [ ] Expose these async methods:
+
+```rust
+pub async fn load(dir: impl Into<PathBuf>) -> Result<Self, AutomationStoreError>;
+pub async fn list(&self) -> Vec<Automation>;
+pub async fn get(&self, id: &AutomationId) -> Option<Automation>;
+pub async fn create(&self, draft: AutomationDraft) -> Result<Automation, AutomationStoreError>;
+pub async fn replace(
+    &self,
+    id: &AutomationId,
+    expected: &AutomationRevision,
+    draft: AutomationReplace,
+) -> Result<Automation, AutomationStoreError>;
+pub async fn patch(
+    &self,
+    id: &AutomationId,
+    expected: &AutomationRevision,
+    patch: AutomationPatch,
+) -> Result<Automation, AutomationStoreError>;
+pub async fn delete(
+    &self,
+    id: &AutomationId,
+    expected: &AutomationRevision,
+) -> Result<(), AutomationStoreError>;
+```
+
+- [ ] Make create/update writes atomic by serializing to canonical TOML, writing a temp file in the automation directory, flushing it, and renaming it over the final path.
+- [ ] Create the automation directory on first write.
+- [ ] Map store errors into precise variants: not found, already exists, missing revision, revision mismatch, validation, parse, and I/O.
+- [ ] Add tests using `tempfile` for empty load, create writes file, replace changes revision, patch keeps unchanged fields, stale revision fails, delete removes file, and startup fails on malformed TOML.
+- [ ] Run `cargo nextest run -p fabro-automation`.
+- [ ] Commit:
+
+```bash
+git add lib/crates/fabro-automation
+git commit -m "feat: persist automations as TOML files"
+```
+
+## Task 3: Carry Automation Metadata Through Runs
+
+**Files:**
+
+- Modify: `lib/crates/fabro-types/src/run_summary.rs`
+- Modify: `lib/crates/fabro-types/src/run.rs`
+- Modify: `lib/crates/fabro-types/src/run_event/run.rs`
+- Modify: `lib/crates/fabro-workflow/src/operations/create.rs`
+- Modify: `lib/crates/fabro-workflow/src/event/convert.rs`
+- Modify: `lib/crates/fabro-store/src/run_state.rs`
+- Modify tests that construct `RunSpec` or `RunCreatedProps`
+
+- [ ] Extend `AutomationRef`:
+
+```rust
+pub struct AutomationRef {
+    pub id: String,
+    #[serde(default)]
+    pub name: Option<String>,
+    #[serde(default, skip_serializing_if = "Option::is_none")]
+    pub trigger_id: Option<String>,
+}
+```
+
+- [ ] Add `automation: Option<AutomationRef>` to `RunSpec` with `#[serde(default, skip_serializing_if = "Option::is_none")]`.
+- [ ] Add `automation: Option<AutomationRef>` to `RunCreatedProps` with the same serde behavior.
+- [ ] Add `automation: Option<AutomationRef>` to `fabro_workflow::operations::CreateRunInput`.
+- [ ] Thread the field through `PersistCreateOptions`, the `RunSpec` built in `persist_validated`, and the `Event::RunCreated` emitted in `persist_created_run`.
+- [ ] In `fabro-store/src/run_state.rs`, set `Run.automation` from `state.spec.automation.clone()` instead of always using `None`.
+- [ ] Preserve backward compatibility: old run specs and old `run.created` events without `automation` deserialize as `None`.
+- [ ] Update all test fixture constructors by setting `automation: None` unless the test specifically checks automation linkage.
+- [ ] Add a focused projection test proving `RunCreatedProps.automation` appears in cached `Run.automation`.
+- [ ] Run:
+
+```bash
+cargo nextest run -p fabro-types
+cargo nextest run -p fabro-workflow operations::create
+cargo nextest run -p fabro-store run_state
+```
+
+- [ ] Commit:
+
+```bash
+git add lib/crates/fabro-types lib/crates/fabro-workflow lib/crates/fabro-store
+git commit -m "feat: associate runs with automations"
+```
+
+## Task 4: Add OpenAPI Contract And Type Reuse
+
+**Files:**
+
+- Modify: `docs/public/api-reference/fabro-api.yaml`
+- Modify: `lib/crates/fabro-api/Cargo.toml`
+- Modify: `lib/crates/fabro-api/build.rs`
+- Create: `lib/crates/fabro-api/tests/automation_round_trip.rs`
+
+- [ ] Add an `Automations` tag.
+- [ ] Add schemas for `Automation`, `AutomationTarget`, `AutomationTrigger`, `AutomationApiTrigger`, `AutomationScheduleTrigger`, `CreateAutomationRequest`, `ReplaceAutomationRequest`, `PatchAutomationRequest`, and `AutomationListResponse`.
+- [ ] Use OpenAPI discriminator `propertyName: type` for trigger variants.
+- [ ] Implement request-body parsing so unknown trigger discriminator values are reported as domain validation errors (`422`), not JSON parse errors (`400`). Use raw DTOs or custom deserialization before converting into `fabro-automation` domain types.
+- [ ] Reuse existing `Run` and paginated run envelope schemas for `POST /automations/{id}/runs` and `GET /automations/{id}/runs`.
+- [ ] Add response codes:
+  - `200` for reads and replace/patch.
+  - `201` for create automation and create run.
+  - `204` for delete.
+  - `400` for malformed JSON or invalid path syntax.
+  - `404` for missing automation.
+  - `409` for duplicate create, stale revision, disabled automation, or disabled/missing `api` trigger.
+  - `422` for domain validation errors.
+  - `428` for missing `If-Match` on `PUT`, `PATCH`, or `DELETE`.
+- [ ] Add `If-Match` header parameters for mutating path operations except `POST /automations`.
+- [ ] Add `ETag` response header on `GET /automations/{id}`, `PUT`, and `PATCH`.
+- [ ] Before adding generated duplicate Rust types, search for matching domain types. If `fabro-automation` serde shape matches a schema exactly, add a `with_replacement(...)` entry in `lib/crates/fabro-api/build.rs`.
+- [ ] Add JSON parity tests for every automation replacement type used by `fabro-api`.
+- [ ] Run `cargo build -p fabro-api`.
+- [ ] Commit:
+
+```bash
+git add docs/public/api-reference/fabro-api.yaml lib/crates/fabro-api
+git commit -m "feat: define automations API contract"
+```
+
+## Task 5: Wire Automation Store Into Server State
+
+**Files:**
+
+- Modify: `lib/crates/fabro-server/Cargo.toml`
+- Modify: `lib/crates/fabro-server/src/server.rs`
+- Modify: `lib/crates/fabro-server/src/test_support.rs`
+
+- [ ] Add `fabro-automation = { path = "../fabro-automation" }` to server dependencies.
+- [ ] Add `automation_store: Arc<AutomationStore>` to `AppState`.
+- [ ] In `build_app_state`, compute the automation directory as:
+
+```rust
+let automation_dir = active_config_path
+    .parent()
+    .unwrap_or_else(|| std::path::Path::new("."))
+    .join("automations");
+```
+
+- [ ] Load `AutomationStore::load(automation_dir)` before constructing `AppState`.
+- [ ] Fail server startup if an existing automation file is malformed.
+- [ ] Add `pub(crate) fn automation_store(&self) -> Arc<AutomationStore>`.
+- [ ] In test support, keep the existing temp `active_config_path` behavior so each test gets its own sibling `automations` directory.
+- [ ] Add a server unit test for empty automation store creation when no automation directory exists.
+- [ ] Run `cargo nextest run -p fabro-server automation_store`.
+- [ ] Commit:
+
+```bash
+git add lib/crates/fabro-server
+git commit -m "feat: load automation store in server state"
+```
+
+## Task 6: Add Automation CRUD Routes
+
+**Files:**
+
+- Create: `lib/crates/fabro-server/src/server/handler/automations.rs`
+- Modify: `lib/crates/fabro-server/src/server/handler/mod.rs`
+- Create: `lib/crates/fabro-server/tests/it/api/automations.rs`
+- Modify: `lib/crates/fabro-server/tests/it/api/mod.rs`
+
+- [ ] Read `docs/internal/logging-strategy.md` and `docs/internal/error-handling-strategy.md` before adding request errors or logs.
+- [ ] Implement `automations::routes()` and merge it into `handler::real_routes()`.
+- [ ] Use `RequiredUser` for CRUD routes.
+- [ ] Implement `GET /automations` by listing store entries, sorting by ID ascending, and returning `{ data, meta: { total } }`.
+- [ ] Implement `POST /automations` with `CreateAutomationRequest`; duplicate ID returns `409`.
+- [ ] Implement `GET /automations/{id}` with `ETag: "<revision>"`.
+- [ ] Implement `PUT /automations/{id}` with `ReplaceAutomationRequest` and required `If-Match`.
+- [ ] Implement `PATCH /automations/{id}` with `PatchAutomationRequest`, shallow patch semantics, and required `If-Match`.
+- [ ] Implement `DELETE /automations/{id}` with required `If-Match`.
+- [ ] Add a helper that parses a quoted or unquoted `If-Match` revision and rejects missing headers with `428`.
+- [ ] Map `AutomationStoreError` to `ApiError`:
+  - not found to `404`
+  - already exists to `409`
+  - missing revision to `428`
+  - revision mismatch to `409`
+  - validation to `422`
+  - parse/I/O to `500` except malformed request bodies, which stay `400`
+- [ ] Add route tests for empty list, create, duplicate create, get with ETag, replace, stale replace, missing `If-Match`, patch clearing description, delete, invalid trigger IDs, duplicate trigger IDs, second trigger with `type = "api"`, and invalid schedule expression.
+- [ ] Run `cargo nextest run -p fabro-server automations`.
+- [ ] Commit:
+
+```bash
+git add lib/crates/fabro-server
+git commit -m "feat: add automation CRUD API"
+```
+
+## Task 7: Add Automation Run Listing And API-Triggered Runs
+
+**Files:**
+
+- Create: `lib/crates/fabro-server/src/automation_materializer.rs`
+- Modify: `lib/crates/fabro-server/src/server.rs`
+- Modify: `lib/crates/fabro-server/src/server/handler/runs.rs`
+- Modify: `lib/crates/fabro-server/src/server/handler/automations.rs`
+- Modify: `lib/crates/fabro-server/src/test_support.rs`
+- Create: `lib/crates/fabro-server/tests/it/api/automations.rs`
+- Modify: `lib/crates/fabro-server/tests/it/api/mod.rs`
+
+- [ ] Extract the common run creation body from `handler/runs.rs::create_run` into a crate-private helper that accepts:
+
+```rust
+struct CreateRunFromManifestRequest {
+    manifest: fabro_api::types::RunManifest,
+    submitted_manifest_bytes: Vec<u8>,
+    explicit_run_id: Option<fabro_types::RunId>,
+    explicit_title_supplied: bool,
+    actor: fabro_types::Principal,
+    headers: axum::http::HeaderMap,
+    automation: Option<fabro_types::AutomationRef>,
+}
+```
+
+- [ ] Keep `POST /runs` behavior unchanged by calling the helper with `automation: None`.
+- [ ] Define a crate-private materializer trait:
+
+```rust
+pub(crate) struct AutomationRunMaterializeInput {
+    pub automation_id: fabro_automation::AutomationId,
+    pub target: fabro_automation::AutomationTarget,
+    pub run_id: fabro_types::RunId,
+    pub user_settings_path: std::path::PathBuf,
+    pub temp_root: std::path::PathBuf,
+}
+
+pub(crate) struct AutomationRunMaterialized {
+    pub manifest: fabro_api::types::RunManifest,
+    pub submitted_manifest_bytes: Vec<u8>,
+}
+
+#[derive(thiserror::Error, Debug)]
+pub(crate) enum AutomationRunMaterializeError {
+    #[error("invalid automation target: {0}")]
+    InvalidTarget(String),
+    #[error("failed to clone automation repository: {0}")]
+    CloneFailed(String),
+    #[error("failed to resolve automation workflow: {0}")]
+    WorkflowNotFound(String),
+    #[error("failed to build run manifest: {0}")]
+    Manifest(String),
+}
+
+#[async_trait::async_trait]
+pub(crate) trait AutomationRunMaterializer: Send + Sync {
+    async fn materialize(
+        &self,
+        input: AutomationRunMaterializeInput,
+    ) -> Result<AutomationRunMaterialized, AutomationRunMaterializeError>;
+}
+```
+
+- [ ] Use a production implementation that:
+  - validates target repository as GitHub `owner/repo`
+  - is constructed with the server GitHub credentials, GitHub API base URL, HTTP client, and cleanup policy needed for clone materialization
+  - creates a per-run temp directory under `AutomationRunMaterializeInput.temp_root`
+  - clones `https://github.com/{owner}/{repo}.git`
+  - uses existing GitHub clone credential helpers when configured
+  - checks out the configured `ref`
+  - resolves the workflow selector using `fabro_config::project::WorkflowLocation::resolve`
+  - builds a `RunManifest` with `fabro_manifest::build_run_manifest`
+  - passes `user_settings_path: Some(state.active_config_path().to_path_buf())`
+- [ ] Use `tokio::process::Command` with argv values for git commands. Do not construct shell command strings. Set `GIT_TERMINAL_PROMPT=0` and explicit timeouts so private-repo credential failures cannot hang request handling.
+- [ ] Store only sanitized repository URLs in run metadata. Do not persist credentialed clone URLs.
+- [ ] Add test support injection for a fake `AutomationRunMaterializer` behind tests or the existing `test-support` feature.
+- [ ] Implement `GET /automations/{id}/runs`:
+  - require the automation to exist
+  - list cached runs from the store
+  - filter by `run.automation.as_ref().is_some_and(|a| a.id == id)`
+  - sort newest first
+  - paginate with `page[limit]` and `page[offset]`
+  - return the existing `{ data, meta }` list shape
+- [ ] Implement `POST /automations/{id}/runs`:
+  - use `RequiredRunToolActor`
+  - require automation `enabled == true`
+  - find the enabled trigger with `type = "api"`
+  - return `409` with API error code `automation_api_trigger_disabled` if not startable
+  - materialize the run manifest
+  - call the shared create-run helper with `AutomationRef { id, name, trigger_id: Some(api_trigger_id) }`
+  - return `201` and the created `Run`
+- [ ] Add route tests using the fake materializer for disabled automation, disabled API trigger, successful run creation, persisted `Run.automation`, and associated run listing.
+- [ ] Add lower-level materializer tests for target URL construction, credential redaction, ref checkout command planning, and workflow path resolution using temp directories. Do not add a live GitHub test.
+- [ ] Run `cargo nextest run -p fabro-server automations`.
+- [ ] Commit:
+
+```bash
+git add lib/crates/fabro-server
+git commit -m "feat: start runs from automations"
+```
+
+## Task 8: Generate Clients And Final Verification
+
+**Files:**
+
+- Modify generated files under `lib/packages/fabro-api-client`
+- Modify generated Rust files under `lib/crates/fabro-api/src` if `cargo build -p fabro-api` updates them
+
+- [ ] Regenerate Rust API code:

+```
+
+- [ ] Regenerate the TypeScript API client:
+
+```bash

+```bash
+git diff -- apps/fabro-web lib/crates/fabro-cli
+```
+
+Expected: no application or CLI command changes caused by this plan.
+
+- [ ] Run focused tests:
+
+```bash
+cargo nextest run -p fabro-automation
+cargo nextest run -p fabro-api
+cargo nextest run -p fabro-server automations
+cargo nextest run -p fabro-server openapi_conformance
+```
+
+- [ ] Run broader checks:
+
+```bash
+cargo +nightly-2026-04-14 fmt --check --all
+cargo +nightly-2026-04-14 clippy --workspace --all-targets -- -D warnings
+```
+
+- [ ] If clippy or tests expose unrelated existing failures, record the exact failing command and failure summary in the implementation handoff.
+- [ ] Commit generated and verification fixes:
+
+```bash
+git add docs/public/api-reference/fabro-api.yaml lib/crates lib/packages/fabro-api-client
+git commit -m "chore: regenerate automation API clients"
+```
+
+## Acceptance Criteria
+
+- A server with no `automations/` directory starts and returns an empty automation list.
+- Creating an automation writes `dirname(active_config_path)/automations/<id>.toml`.
+- Updating or deleting an automation requires `If-Match`.
+- Stale revisions are rejected.
+- Invalid automation and trigger shapes are rejected with `422`.
+- Disabling the `api` trigger makes the automation not startable through `POST /automations/{id}/runs`.
+- A successful API-triggered automation run returns a normal `Run` response with `automation.id`, `automation.name`, and `automation.trigger_id`.
+- `GET /automations/{id}/runs` returns runs linked to that automation.
+- No cron scheduler, web UI exposure, or CLI exposure is added.
+

+# Simplify: Code Review and Cleanup
+
+Review changes vs. origin for reuse, quality, and efficiency. Fix any issues found.
+
+## Phase 1: Identify Changes
+
+Run git diff (or git diff HEAD if there are staged changes) to see what changed. If there are no git changes, review the most recently modified files that the user mentioned or that you edited earlier in this conversation.
+
+## Phase 2: Launch Three Review Agents in Parallel
+
+Use the Agent tool to launch all three agents concurrently in a single message. Pass each agent the full diff so it has the complete context.
+
+### Agent 1: Code Reuse Review
+
+For each change:
+
+1. Search for existing utilities and helpers that could replace newly written code. Use Grep to find similar patterns elsewhere in the codebase — common locations are utility directories, shared modules, and files adjacent to the changed ones.
+2. Flag any new function that duplicates existing functionality. Suggest the existing function to use instead.
+3. Flag any inline logic that could use an existing utility — hand-rolled string manipulation, manual path handling, custom environment checks, ad-hoc type guards, and similar patterns are common candidates.
+
+Note: This is a greenfield app, so focus on maximizing simplicity and don't worry about changing things to achieve it.
+
+### Agent 2: Code Quality Review
+
+Review the same changes for hacky patterns:
+
+1. Redundant state: state that duplicates existing state, cached values that could be derived, observers/effects that could be direct calls
+2. Parameter sprawl: adding new parameters to a function instead of generalizing or restructuring existing ones
+3. Copy-paste with slight variation: near-duplicate code blocks that should be unified with a shared abstraction
+4. Leaky abstractions: exposing internal details that should be encapsulated, or breaking existing abstraction boundaries
+5. Stringly-typed code: using raw strings where constants, enums (string unions), or branded types already exist in the codebase
+
+Note: This is a greenfield app, so be aggressive in optimizing quality.
+
+### Agent 3: Efficiency Review
+
+Review the same changes for efficiency:
+
+1. Unnecessary work: redundant computations, repeated file reads, duplicate network/API calls, N+1 patterns
+2. Missed concurrency: independent operations run sequentially when they could run in parallel
+3. Hot-path bloat: new blocking work added to startup or per-request/per-render hot paths
+4. Unnecessary existence checks: pre-checking file/resource existence before operating (TOCTOU anti-pattern) — operate directly and handle the error
+5. Memory: unbounded data structures, missing cleanup, event listener leaks
+6. Overly broad operations: reading entire files when only a portion is needed, loading all items when filtering for one
+
+## Phase 3: Fix Issues
+
+Wait for all three agents to complete. Aggregate their findings and fix each issue directly. If a finding is a false positive or not worth addressing, note it and move on — do not argue with the finding, just skip it.
+
+When done, briefly summarize what was fixed (or confirm the code was already clean).

+Cleanup complete.
+
+Fixed:
+- `lib/crates/fabro-server/src/automation_materializer.rs`
+  - Corrected the materializer workflow path test to use `flows/deps.fabro`.
+  - The previous extensionless `flows/deps` was treated by `WorkflowLocation::resolve` as a workflow selector/literal and failed with `workflow not found`.
+
+Validated:
+- `cargo nextest run -p fabro-automation` ✅
+- `cargo nextest run -p fabro-server 'automation_'` ✅
+- `cargo nextest run -p fabro-api automation` ✅
+- `cargo +nightly-2026-04-14 fmt --check --all` ✅
+- `cargo +nightly-2026-04-14 clippy -q -p fabro-server --all-targets -- -D warnings` ✅
