+# Adapter Privacy Checklist
+
+Privacy checklist for external adapters.
+
+## Checklist
+- [ ] Adapter declares whether network access is required.
+- [ ] No data is sent without user consent.
+- [ ] Adapter does not collect telemetry.
+- [ ] Credentials are not stored in code.
+- [ ] Authentication uses environment variables or secure storage.
+- [ ] Data sent to external services is documented.
+- [ ] Users are informed before any network request is made.
+
+## Rules
+- All adapters must pass this checklist before being used with real data.
+- Adapters that fail the checklist may only be used with synthetic data.
+- This checklist should be reviewed when adding new adapters.

+# Adapter Timeout Policy
+
+Timeout rules for external adapter calls.
+
+## Default Timeouts
+| Adapter Type | Default Timeout | Max Timeout |
+|-------------|:---------------:|:-----------:|
+| External API | 30 seconds | 120 seconds |
+| Local process | 60 seconds | 300 seconds |
+| File I/O | 10 seconds | 60 seconds |
+
+## Rules
+- Adapters should have configurable timeout values.
+- Timeout errors should be retried at least once.
+- If a timeout persists, return uncertainty=1.0.
+- Document timeout behavior in each adapter's docstring.
+- Timeouts should not block the pipeline — use async or thread-based timeout.

+# Benchmark Limitation Registry
+
+Known limitations of the project's benchmarks.
+
+| Benchmark | Limitation |
+|-----------|------------|
+| 500-AMP benchmark | AUROC is charge-inflated (0.7792; collapses to 0.5103 under exact charge control) |
+| Cross-dataset | DRAMP + Swiss-Prot decoys may share database artifacts |
+| Simulation ablation | Modules are tested on AMP-vs-decoy, not their designed task |
+| Within-AMP hemolysis | Small reference set (n=179), HC50 values from literature with high variability |
+| Easy baseline | Charge density beats ensemble — expected, pipeline optimizes for safety |
+
+## Rules
+- Every benchmark result must reference its limitations.
+- Limitations must be stated alongside the result, not hidden.
+- When a limitation is resolved, update this registry.
+- If a benchmark has no documented limitations, it's incomplete.

+
+Standard metadata fields for external adapters.

+## Required Fields
+| Field | Type | Description |
+|-------|------|-------------|
+| name | string | Adapter name |
+| version | string | Adapter version |
+| type | string | simulation, external_api, local_process |
+| requires_network | boolean | Whether network access is needed |
+
+## Optional Fields
+| Field | Type | Description |
+|-------|------|-------------|
+| timeout | integer | Default timeout in seconds |
+| retry_count | integer | Number of retries on failure |
+| rate_limit | integer | Maximum requests per minute |
+| dependencies | list | Required Python packages |
+
+## Example
+```json
+{
+  "name": "example_adapter",
+  "version": "0.1.0",
+  "type": "external_api",
+  "requires_network": true,
+  "timeout": 30,
+  "retry_count": 2

+
+Standard output schema for external adapters.

+## SimulationResult Fields
+| Field | Type | Description |

+| scope | list | What was modeled |
+| scores | dict | Score key-value pairs |
+| uncertainty | float | 0-1 scale, higher = less certain |
+| calibration_set | string or null | Reference to calibration data |
+| validated_against | list | Validation datasets |
+| notes | list | Human-readable notes |
+
+## Rules
+- All adapters must return a SimulationResult.
+- uncertainty=1.0 means completely uncertain (do not use).
+- calibration_set=null means no calibration data exists.
+- notes should include warnings, limitations, and context.

+# External Result Cache Manifest
+
+Records cached results from external adapter calls.
+
+## Format
+```json
+{
+  "cache_version": "1.0",
+  "created_at": "ISO 8601",
+  "entries": [
+    {
+      "adapter": "adapter_name",

+      "ttl_seconds": 86400
+    }
+  ]
+}
+```
+
+## Rules
+- Cache entries should have a TTL (time-to-live).
+- Cached results should be validated against the adapter schema.
+- Cache should be invalidated when the adapter version changes.
+- Cached results must be clearly labeled as cached.
+- Cache location: `outputs/adapter_cache/`.

+# Adapter Error Taxonomy
+
+Types of errors that external adapters can produce.
+
+| Error Type | Meaning | Recovery |
+|-----------|---------|----------|
+| connection | Network or DNS failure | Retry with backoff |
+| timeout | Request exceeded time limit | Increase timeout or retry |
+| rate_limit | Too many requests | Reduce frequency, wait |
+| auth | Authentication failure | Check credentials |
+| validation | Response failed schema check | Check adapter version |
+| internal | Adapter raised an exception | Check adapter code |
+| not_found | Resource not available | Check resource path |
+
+## Rules
+- All adapters should handle all error types gracefully.
+- Errors should return a SimulationResult with uncertainty=1.0.
+- Errors should include a human-readable message.
+- Connection and timeout errors should be retryable.
