Implement first so everything +else can import them. + +1. Write `errors.test.ts` (inline in `public-api.test.ts` is fine): + - `CoreError` sets `name`, `code`, `context`. + - `PlanningError` extends `CoreError`, code `PLANNING_ERROR`. + - `CompositionError` extends `CoreError`, code `COMPOSITION_ERROR`. + - `instanceof CoreError` works for subclasses. +2. Implement `errors.ts`. +3. Implement `operation.ts` — all types from spec: `OperationKind`, + `OperationSpec`, `CacheDeclaration`, `ArtifactDeclaration`, + `NetworkPolicy`, `CredentialDeclaration`, `Operation`. + - `Operation` is an **interface**; the concrete implementation lives in + `internal/node.ts` (Step 4). No implementation here, types only. + +### Step 2: Runtime types + +**Files:** `runtime.ts` + +1. Implement all types from spec: `RuntimeMode`, `RuntimeResult`, + `OperationOutcome`, `PlanContext`, `Artifact`, `Runtime`. + - Types only, no implementation. `Runtime` is an interface implemented by + consumers (and by test doubles). + +### Step 3: Internal node + spec merge + +**Files:** `internal/node.ts`, `internal/merge.ts` + +1. Write `composition.test.ts` (covers merge behavior): + - `mergeSpecs(a, b)`: scalar fields — `b` wins if defined; `dependsOn` + and `tags` — arrays concatenated and deduplicated; nested objects + (`cache`, `credentials`, `artifacts`) — `b` wins if defined (no deep + merge for v1). + - `OperationNode` created by `run()` carries empty `predecessors`/`siblings`. + - `after(p)` returns a new node with `predecessors = [...this.predecessors, p]`. + - `with(s)` returns a new node with `siblings = [...this.siblings, s]`. + - `named(n)` returns a new node with `spec.name = n`. + - `tagged(...t)` returns a new node with `spec.tags` concatenated. +2. Implement `internal/node.ts`: + - `createNode(kind, spec): OperationNode` — factory. + - Methods return **new** nodes (immutable). Use spread to copy. + - `predecessors` and `siblings` are `OperationNode[]` (internal fields not + on the public `Operation` interface — use a type assertion or a branded + field). +3. Implement `internal/merge.ts`: + - `mergeSpecs(a: Partial, b: Partial): Partial` + - Export a helper `concatDedupe(arr: readonly string[]): string[]`. + +### Step 4: Composables (run, pipeline, parallel, when, matrix) + +**Files:** `composables/run.ts`, `pipeline.ts`, `parallel.ts`, `when.ts`, `matrix.ts` + +1. Write per-composable test files in `__tests__/composables/`. +2. Implement each composable — all are thin wrappers over `createNode`: + - `run(spec): Operation` → `createNode(spec.kind ?? "run", spec)`. + - `pipeline(...ops): Operation` → chain: each op gets the previous as a + predecessor. Returns the last node with the chain wired. Specifically, + `pipeline(a, b, c)` produces nodes where `b.after(a)`, `c.after(b)`, + and the returned node is `c` (the tail). The planner walks predecessors + to discover the full chain. + - `parallel(...ops): Operation` → returns a synthetic join node with all + ops as siblings. No dependency edges between siblings. The join node + has `kind: "custom"`, `name: "parallel-join"`, and `siblings = ops`. + **Design note:** the join node is a planning artifact; in the emitted + `OperationSpec[]` it does not appear as a separate operation — only the + siblings appear, with no inter-sibling `dependsOn`. The join exists + solely so `workflow()` can treat `parallel(...)` as a single root. + - `when(cond, op): Operation` → returns a new node with `spec.condition = cond`. + - `matrix(dims, op): Operation` → returns a new node with `spec.matrix = dims` + and a flag marking it for expansion. Validation of dims (non-empty + arrays) happens at planning time, not call time (laziness: `matrix()` + itself must not throw for lazy correctness — validation deferred to + planning). **Correction:** the spec says `matrix({ node: [] }, op)` + raises `CompositionError`. This happens during planning, not at call + time, to preserve laziness. The test should call `workflow(...).plan()` + and expect the error there. + +### Step 5: Condition evaluator + ID generation + canonical JSON + +**Files:** `internal/conditions.ts`, `internal/ids.ts`, `internal/canonical.ts` + +1. Write `conditions.test.ts`: + - Tokenizer + recursive descent parser per the grammar in the spec. + - `evaluate("schedule == 'nightly'", { schedule: "nightly" })` → `true`. + - `evaluate("a && b || !c", { a: true, b: false, c: false })` → `true`. + - `evaluate("missing", {})` → `false` (unknown identifier is falsy). + - `evaluate("true", {})` → `true`. + - `evaluate("1 == 1", {})` → `true` (number literal). + - Malformed expression throws `CompositionError` with code + `INVALID_CONDITION`. +2. Implement `internal/conditions.ts`: + - `evaluateCondition(expr: string, context: PlanContext | undefined): boolean` + - If `context` is `undefined`, return `true` (include by default). + - **No `eval`, no `new Function`.** Hand-rolled tokenizer + parser. +3. Implement `internal/canonical.ts`: + - `canonicalJson(value: unknown): string` — stable JSON serialization: + keys sorted lexicographically, compact (no indentation), `undefined` + omitted, array order preserved. This is the shared primitive for + id computation (per ADR-006). The `ir` package implements the same + algorithm independently for `serializePlan`. +4. Implement `internal/ids.ts` (per ADR-006): + - `computeOperationId(kind, name, context): string` → `op-<64 hex>`. + Uses `node:crypto.createHash('sha256')` over `canonicalJson({ kind, name, context })`. + - `buildIdContext(node, index): Record` — assembles the + context record from `spec.id` (as `userId` if present), `spec.command`, + `spec.args`, matrix dimension values, and `index`. + - No external hashing library. No counter-based suffixes — uniqueness is + by construction via the context record. + - `resolveName(node): string` — `spec.name || spec.command || "operation"`. + +### Step 6: Planner (graph walk, expansion, validation) + +**Files:** `internal/plan.ts` + +This is the core engine. It is called by `workflow().plan()`. + +1. Write `dag.test.ts` and `matrix.test.ts`: + - Cycle: `a.after(b)`, `b.after(a)` → `CompositionError` with ids in context. + - True duplicate: two `run({ command: "eslint", name: "lint" })` with no + other discriminating fields → same `op-` id → `CompositionError`. + - Different commands, same name: `run({ name: "x", command: "a" })` and + `run({ name: "x", command: "b" })` → distinct `op-` ids (command is in + context). + - Matrix expansion: `matrix({ node: ["20", "24"] }, op)` → 2 nodes, env + injected, distinct content-addressed ids. + - Matrix empty array → `CompositionError`. + - Matrix non-array → `CompositionError`. + - Topo sort respects `dependsOn` edges. + - Id stability: same workflow planned twice produces identical ids. +2. Implement `internal/plan.ts`: + - `planWorkflow(roots: OperationNode[], runtime: Runtime): Promise` + - Algorithm: + 1. **Discover** — DFS/BFS from roots, following `predecessors` and + `siblings`. Collect all nodes. Detect structural issues (null refs). + 2. **Expand matrix** — for each node with `spec.matrix`, generate child + nodes via cartesian product. Inject `MATRIX_` env. Children + inherit predecessors/siblings. Replace the template node with + children in the node set. Validate dims here (empty/non-array → + `CompositionError`). + 3. **Assign ids** — walk in discovery order. For each node, build the + `context` record (`buildIdContext`), resolve the name + (`resolveName`), and compute `computeOperationId(kind, name, context)`. + Track `usedIds`; if a computed id collides (true duplicate — same + `{ kind, name, context }`), raise `CompositionError` with the + duplicate `op-` id in `context`. + 4. **Resolve edges** — for each node, resolve `predecessors` refs to + their assigned ids, merge with user `spec.dependsOn`, deduplicate. + 5. **Cycle detection** — build adjacency list from `dependsOn`, run + DFS with coloring (white/gray/black). Gray→gray edge = cycle → + `CompositionError` with the cycle path in `context`. + 6. **Topo sort** — Kahn's algorithm or DFS post-order. + 7. **Evaluate conditions** — for each node in topo order, if + `spec.condition` exists, evaluate against `runtime.context`. If + false, mark as skipped (don't call `runtime.evaluate`, or call it + and let the runtime decide — **decision: call `runtime.evaluate` + for all nodes; the planner passes the condition result via + `OperationSpec.condition` and the runtime decides**). Actually, + simpler: the planner evaluates the condition and if false, sets + `status: "skipped"` in the outcome without calling evaluate. But + the spec says the operation is "still recorded in the graph." So: + build the `OperationSpec` with `condition` set, call + `runtime.evaluate(spec)` for all, and in Execution mode the + runtime checks the condition. **Final decision:** the planner + evaluates conditions and skips `runtime.evaluate` for false + conditions, producing a synthetic `"skipped"` outcome. The + `OperationSpec.condition` field is still populated so compilers + can emit it. This keeps the runtime simple. + 8. **Evaluate** — for each non-skipped node in topo order, call + `runtime.evaluate(spec)`. Collect `OperationOutcome`s. + 9. **Finalize** — call `runtime.finalize()`, merge with planner + metadata (operations list, duration). + +### Step 7: Workflow composable + public index + +**Files:** `composables/workflow.ts`, `index.ts` + +1. Write `__tests__/composables/workflow.test.ts` and `runtime-modes.test.ts`: + - `workflow("ci", parallel(a, b), pipeline(c, d))` — roots are the + parallel join node and the pipeline tail. + - `wf.plan(planRuntime)` returns `RuntimeResult` with all operations. + - Plan mode: no side effects (spies on fs/process/fetch). + - Execution mode: `evaluate` called for each non-skipped op. + - Compile mode: `finalize` returns an artifact with content. +2. Implement `composables/workflow.ts`: + - `workflow(name, ...roots): Workflow` + - `Workflow.plan(runtime)` → delegates to `internal/plan.ts`. +3. Implement `index.ts` — re-export everything per the spec's public export + list. **Do not export anything from `internal/`.** + +### Step 8: Laziness + public API tests + +**Files:** `__tests__/laziness.test.ts`, `__tests__/public-api.test.ts` + +1. `laziness.test.ts`: + - Spy on `child_process.spawn`, `fs.writeFileSync`, `fs.readFile`, + `globalThis.fetch`. + - Call every composable + `workflow().plan(planRuntime)`. + - Assert no spy was called. +2. `public-api.test.ts`: + - Import every symbol from `@sverka/core` (via `src/index.ts`). + - Assert each is defined (typeof check). + - Assert `internal/` modules are NOT importable (attempt import and + expect failure — or just verify they're not in the export list). + +## Key design decisions (for the builder) + +1. **Immutability:** All `Operation` methods return new nodes. Never mutate. +2. **Laziness:** Composables do zero I/O. Validation that can be deferred + (matrix dims, cycle detection) happens in the planner, not at call time. + The only exception is `CompositionError` for obviously invalid input at + call time — but per the spec, even matrix validation is deferred to + planning to preserve laziness. **Rule: composables never throw.** +3. **Internal modules:** `src/internal/*` is implementation detail. Not + exported from `index.ts`. The builder should use `// @internal` JSDoc + tags. +4. **No `any`:** Use `unknown` and narrow. `OperationSpec.matrix` values are + `readonly unknown[]` — narrow to `string | number` during expansion. +5. **`exactOptionalPropertyTypes: true`** is on in tsconfig. Be careful: + `optionalField?: T` means `T | undefined`, and you cannot assign + `undefined` explicitly — only omit the key. Use conditional spread: + `{ ...(x !== undefined && { field: x }) }`. +6. **`verbatimModuleSyntax: true`** is on. Use `export type { X }` for + type-only re-exports, `export { X }` for values. The spec's `index.ts` + already follows this pattern. +7. **`noUncheckedIndexedAccess: true`** is on. Array/record access returns + `T | undefined`. Narrow before use. +8. **Content-addressed ids (ADR-006):** Operation ids are `op-<64 hex>` + from SHA-256 of `canonicalJson({ kind, name, context })`. Use + `node:crypto.createHash('sha256')` — no external library.

User-provided +`spec.dependsOn` strings (explicit ids) are merged with resolved predecessor +ids, deduplicated. + +### ID assignment + +Operation ids are **content-addressed** per [ADR-006](../../engdocs/adr/ADR-006-sha256-content-addressed-plan-ids.md). +The planner computes a deterministic SHA-256 hash over the canonical JSON +of `{ kind, name, context }`, hex-encodes it, and prefixes with `op-`: + +``` +op-<64 hex chars> +``` + +- **`kind`** — the `OperationKind`. +- **`name`** — `spec.name` if provided, else `spec.command` if provided, + else a fallback string `operation` (the hash still distinguishes via + `context`). +- **`context`** — a record of discriminating fields: matrix dimension + values, `spec.id` (if user-provided), `spec.command`, `spec.args`, and + a positional `index` within the discovery walk. This ensures two + operations with the same kind and name but different commands or matrix + values get distinct ids by construction. + +**User-provided `spec.id`:** If present, it is included in the `context` +record (under the key `userId`), influencing the hash. It is **not** used +as the operation id directly — content-addressing is always enforced so +that ids remain reproducible by any consumer without contacting the +planner. This preserves cache stability and plan diffing. + +**Canonical JSON:** Keys sorted lexicographically, compact (no +indentation), `undefined` omitted, array order preserved. This is the +same canonical form used by the `ir` package's `serializePlan` (see +[spec 02-ir](../02-ir/spec.md)). The `core` package implements this +independently in `internal/canonical.ts` (no dependency on `ir`; the +algorithm is simple and specified in ADR-006). + +**Duplicate detection:** Because ids are content-addressed, two operations +with identical `{ kind, name, context }` produce the same id. This is +detected during planning and raises `CompositionError` with the duplicate +id in `context`. In practice this means the user has defined the same +operation twice — the fix is to differentiate via `name`, `command`, or +`spec.id`. + +**Implementation:** `core` owns `computeOperationId` in +`internal/ids.ts` using Node's built-in `node:crypto` (`createHash('sha256')`). +No external dependency. The `ir` package's `computeOperationId` (spec +02-ir) implements the same algorithm for validation purposes; both +reference ADR-006 as the source of truth. + +### Matrix expansion + +`matrix({ dim: [v1, v2, ...] }, op)` produces the cartesian product of all +dimensions. Each combination becomes a separate `OperationNode` with: +- A content-addressed id per the rule above. The dimension values are + included in the `context` record (e.g. `{ node: "24", os: "linux" }`), + so each combination yields a distinct hash by construction — no + suffix-based disambiguation needed. +- The dimension values injected into `spec.env` as `MATRIX_=` + (uppercased) so executors and compilers can reference them. +- The same predecessor/sibling edges as the template operation. + +Empty dimension arrays or non-array values raise `CompositionError`. + +### Condition evaluation + +`when(condition, op)` attaches a `condition` string to the operation. During +planning, the condition is evaluated against `Runtime.context` (a +`PlanContext`). The expression syntax is a deliberately minimal, safe subset +(no `eval`, no `Function` constructor): + +``` +expression := orExpr +orExpr := andExpr ( '||' andExpr )* +andExpr := notExpr ( '&&' notExpr )* +notExpr := '!' notExpr | comparison +comparison := operand ( ( '==' | '!=' ) operand )? +operand := identifier | stringLit | numberLit | 'true' | 'false' +identifier := [a-zA-Z_][a-zA-Z0-9_.]* // looked up in PlanContext +stringLit := "'" [^']* "'" +numberLit := [0-9]+ ( '.'

These rules are completely inappropriate for a modern TypeScript project targeting Node 24+. The .codacy.yml disable_rules approach does not work — Codacy docs confirm that tools can only be enabled/disabled via the Code patterns page, not via .codacy.yml. Instead, Codacy reads the tool's native configuration file (.eslintrc.json for ESLint 8).
