+# API Contract Template
+
+A contract is the **frozen, reviewed interface** between two or more components. When task A produces a shared model, DTO, schema, event payload, or public API, and task B consumes it, they must not reverse-engineer each other's implementation — they must read the contract.
+
+Save the filled contract at `_docs/02_document/contracts/<component>/<name>.md`. Reference it from the producing task's `## Contract` section and from every consuming task's `## Dependencies` section.
+

+# Contract: [contract-name]
+
+**Component**: [component-name]
+**Producer task**: [TRACKER-ID] — [task filename]
+**Consumer tasks**: [list of TRACKER-IDs or "TBD at decompose time"]
+**Version**: 1.0.0
+**Status**: [draft | frozen | deprecated]
+**Last Updated**: [YYYY-MM-DD]
+
+## Purpose
+
+Short statement of what this contract represents and why it is shared (1–3 sentences).
+
+## Shape
+
+Choose ONE of the following shape forms per the contract type:
+
+### For data models (DTO / schema / event)
+
+```[language]
+// language-native type definitions — e.g., Python dataclass, C# record, TypeScript interface, Rust struct, JSON Schema
+```
+
+For each field:
+
+| Field | Type | Required | Description | Constraints |
+|-------|------|----------|-------------|-------------|
+| `id` | `string` (UUID) | yes | Unique identifier | RFC 4122 v4 |
+| `created_at` | `datetime` (ISO 8601 UTC) | yes | Creation timestamp | |
+| `...` | ... | ... | ... | ... |
+
+### For function / method APIs
+
+| Name | Signature | Throws / Errors | Blocking? |
+|------|-----------|-----------------|-----------|
+| `do_x` | `(input: InputDto) -> Result<OutputDto, XError>` | `XError::NotFound`, `XError::Invalid` | sync |
+| ... | ... | ... | ... |
+
+### For HTTP / RPC endpoints
+
+| Method | Path | Request body | Response | Status codes |
+|--------|------|--------------|----------|--------------|
+| `POST` | `/api/v1/resource` | `CreateResource` | `Resource` | 201, 400, 409 |
+| ... | ... | ... | ... | ... |
+
+## Invariants
+
+Properties that MUST hold for every valid instance or every allowed interaction. These survive refactors.
+
+- Invariant 1: [statement]
+- Invariant 2: [statement]
+
+## Non-Goals
+
+Things this contract intentionally does NOT cover. Helps prevent scope creep.
+
+- Not covered: [statement]
+
+## Versioning Rules
+
+- **Breaking changes** (field renamed/removed, type changed, required→optional flipped) require a new major version and a deprecation path for consumers.
+- **Non-breaking additions** (new optional field, new error variant consumers already tolerate) require a minor version bump.
+
+## Test Cases
+
+Representative cases that both producer and consumer tests must cover. Keep short — this is the contract test surface, not an exhaustive suite.
+
+| Case | Input | Expected | Notes |
+|------|-------|----------|-------|
+| valid-minimal | minimal valid instance | accepted | |
+| invalid-missing-required | missing `id` | rejected with specific error | |
+| edge-case-x | ... | ... | |
+
+## Change Log
+
+| Version | Date | Change | Author |
+|---------|------|--------|--------|

+## Decompose-skill rules for emitting contracts
+
+A task is a **shared-models / shared-API task** when ANY of the following is true:
+
+- The component spec lists it as a shared component (under `shared/*` in `module-layout.md`).
+- The task's **Scope.Included** mentions any of: "public interface", "DTO", "schema", "event", "contract", "API endpoint", "shared model".
+- The task is parented to a cross-cutting epic (`epic_type: cross-cutting`).
+- The task is depended on by ≥2 other tasks across different components.
+
+For every shared-models / shared-API task:
+
+1. Create a contract file at `_docs/02_document/contracts/<component>/<name>.md` using this template.
+2. Fill in Shape, Invariants, Non-Goals, Versioning Rules, and at least 3 Test Cases.
+3. Add a mandatory `## Contract` section to the task spec that links to the contract file:
+
+   ```markdown
+   ## Contract
+
+   This task produces/implements the contract at `_docs/02_document/contracts/<component>/<name>.md`.
+   Consumers MUST read that file — not this task spec — to discover the interface.
+   ```
+
+4. For every consuming task, add the contract path to its `## Dependencies` section as a document dependency (not a task dependency):
+
+   ```markdown
+   ### Document Dependencies
+   - `_docs/02_document/contracts/<component>/<name>.md` — API contract produced by [TRACKER-ID].
+   ```
+
+5. If the contract changes after it was frozen, the producer task must bump the `Version` and note the change in `Change Log`. Consumers referenced in the contract header must be notified (surface to user via Choose format).
+
+## Code-review-skill rules for verifying contracts
+
+Phase 2 (Spec Compliance) adds a check:
+
+- For every task with a `## Contract` section:
+  - Verify the referenced contract file exists at the stated path.
+  - Verify the implementation's public signatures (types, method shapes, endpoint paths) match the contract's Shape section.
+  - If they diverge, emit a `Spec-Gap` finding with High severity.
+- For every consuming task's Document Dependencies that reference a contract:
+  - Verify the consumer's imports / calls match the contract's Shape.
+  - If they diverge, emit a `Spec-Gap` finding with High severity and a hint that either the contract or the consumer is drifting.
