+2. Run `make coverage-check` and verify coverage meets the threshold. If coverage dropped below the threshold, write additional tests before proceeding.
 3. If you modified or created integration-level code (database interactions, multi-package pipelines, module registration), also run `make test-integration`.

 Never skip these steps. Never say "tests should be run" — actually run them and report the results.
 
+### Code Coverage Requirement (PRIME DIRECTIVE)
+
+**The code coverage requirement is 95% lines and 95% functions. This is the floor, not a target to exceed at all costs.**
+
+- The CI gate (`.github/workflows/ci.yml`) and `make coverage-check` both enforce `--fail-under-lines 95 --fail-under-functions 95`, with `--ignore-filename-regex` excluding structurally untestable infrastructure (TUI event loop, HTTP server bootstrap, secrets providers requiring live services, the CLI `main` entry point).
+- **100% is explicitly NOT a goal.** It was attempted (GRC-144) and proven not worthwhile: the last ~1% is genuinely-unreachable defensive code — `?` continuations on `.with_context()`/`.map_err()` for errors that cannot occur (an in-memory writer never fails, serde never fails to serialize a valid struct, poisoned-mutex fallbacks can't be triggered deterministically), and dead match arms like ureq's "2xx in `Err::Status`" branch. Pushing past ~99% only incentivises deleting graceful error handling, which is a net negative for code quality.
+- **Do not lower the gate** to make a change pass. If a change drops coverage below 95%, write tests for the new code. If 95% genuinely cannot be met because the new code is untestable infrastructure, add it to the `--ignore-filename-regex` with a comment explaining why — do not weaken the percentage.
+- **Do not chase 100%.** Once a module's reachable code is covered and the suite is green at ≥95%, stop. Time spent fighting unreachable `?` branches is better spent elsewhere.
+
 ### 2. Every Code Change Requires Corresponding Test Changes
 
 - **New feature/function:** Write unit tests in the same package (`foo_test.go` alongside `foo.go`). Test the happy path, at least one error path, and edge cases.

+# Security Policy
+
+## Supported Versions
+
+| Version | Supported          |
+| ------- | ------------------ |
+| 0.1.x   | :white_check_mark: |
+
+Only the latest release receives security patches. We recommend always running the most recent version.
+
+## Reporting a Vulnerability
+
+**Please do NOT report security vulnerabilities through public GitHub issues.**
+
+Instead, report vulnerabilities through [GitHub Security Advisories](https://github.com/grcengineering/ocean/security/advisories/new).
+
+### What to Include
+
+- Description of the vulnerability
+- Steps to reproduce (proof of concept if possible)
+- Impact assessment (what an attacker could achieve)
+- Affected version(s)
+- Any suggested fix or mitigation
+
+### Response Timeline
+
+| Action | SLA |
+| ------ | --- |
+| Acknowledgment of report | **72 hours** |
+| Initial triage and severity assessment | **5 business days** |
+| Patch for critical severity (CVSS >= 9.0) | **7 days** |
+| Patch for high severity (CVSS 7.0-8.9) | **14 days** |
+| Patch for medium severity (CVSS 4.0-6.9) | **30 days** |
+| Patch for low severity (CVSS < 4.0) | **90 days** |
+
+### Process
+
+1. **Report** — Submit via GitHub Security Advisory (preferred) or email security@grc.engineering.
+2. **Acknowledge** — We confirm receipt within 72 hours and assign a tracking ID.
+3. **Triage** — We assess severity using CVSS v3.1/v4.0 and determine affected versions.
+4. **Fix** — We develop and test a patch within the SLA above.
+5. **Disclose** — We publish a GitHub Security Advisory with the fix. We follow coordinated disclosure — we will not disclose before a fix is available unless 90 days have elapsed since the initial report.
+6. **Credit** — We credit reporters in the advisory unless they prefer to remain anonymous.
+
+## Security Practices
+
+OCEAN follows these security practices:
+
+- **Dependency auditing**: `cargo-audit` runs in CI on every push and PR, failing builds on known vulnerabilities.
+- **Static analysis**: Clippy with `-D warnings` enforced in CI.
+- **No unsafe code**: We minimize use of `unsafe` blocks. Any `unsafe` usage requires justification and review.
+- **Input validation**: All CLI inputs and external data (API responses, file contents) are validated at system boundaries.
+- **Credential handling**: OCEAN processes API credentials for evidence collection. Credentials are never logged, stored in plaintext, or included in evidence output.
+- **Supply chain**: We use `Cargo.lock` for reproducible builds and audit dependencies for known vulnerabilities.
+
+## Scope
+
+This security policy covers:
+
+- The `ocean` CLI binary and library
+- All GRC check modules in the `checks/` directory
+- The OCEAN container image published to GHCR
+
+Out of scope:
+
+- Third-party infrastructure that OCEAN connects to (cloud provider APIs, SaaS platforms)
+- Vulnerabilities in upstream dependencies (report those to the respective maintainers, but do let us know so we can assess impact)
