+# Apply Gate (Phase 6)
+
+The Apply Gate protects the repository from untrusted code mutations generated by provider LLMs. It defines a strict boundary where proposed modifications are checked, applied safely (avoiding forbidden pathways), and automatically validated.
+
+## Commands
+
+### ctxt apply
+
+Applies a structured proposal to the workspace.
+
+```bash
+ctxt apply [proposal_path] [--yes]
+```
+
+* **`proposal_path`** (optional): The path to the proposal JSON to apply. Defaults to `proposals/proposal.latest.json` if not specified.
+* **`--yes` / `-y`** (optional): Bypasses the confirmation prompt. Recommended for automation and testing.
+
+### ctxt validate
+
+Runs the validation commands associated with the latest applied proposal to ensure that the codebase is healthy.
+
+```bash
+ctxt validate
+```
+
+## Security Guardrails
+
+The Apply Gate enforces several security boundaries to satisfy the project constitution:
+
+1. **Path-Traversal Prevention**: File paths within operations are parsed and blocked if they contain `..` or are absolute.
+2. **Directory Isolation**: Changes targeting system folders (like `.git/`, `.comptext/`, `target/`, or `reports/`) are rejected and trigger a security policy failure.
+3. **Secret Storage Isolation**: Changes modifying `.env` or files containing key/token suffixes (like `.key`, `.pem`, `.pfx`, `.p12`) are blocked.
+4. **Validation Loop**: Every successful apply operation is followed by executing the `validation_commands` declared inside the proposal. If validation fails, the process aborts.

+COMMANDS_RUN:
+- `cargo fmt --all --check`
+- `cargo check`
+- `cargo test`
+- `cargo clippy -- -D warnings`
+VALIDATION:
+- Formatting verified clean with `cargo fmt --all --check`.
+- Project build checked and verified using `cargo check`.
+- 18 unit and integration tests successfully verified via `cargo test`.
+- Clippy completed cleanly with no warnings or errors.
+ARTIFACTS:
+- None (This phase implemented the execution engine and validation gates).
+GIT:
+- Stage, commit, and push pending.
+NETWORK:
+- offline-only (Dummy validations run completely offline).
+SECRETS:
+- verified-redacted (System files and credentials blocked from mutation path).
+POLICY_DECISIONS:
+- Apply security guardrails implemented: rejected traversing paths, absolute paths, system folders, and credentials.

+## Detailed Notes & Output Samples
+
+### Safety Validations
+`apply` parses the operations block of the Proposal, validates every path against the security rules, and blocks execution if any of the following rules are violated:
+- Path contains directory traversal (`..`)
+- Path is absolute
+- Path target lies in a system directory (`.git/`, `.comptext/`, `target/`, `reports/`)
+- Path targets secret files or credentials (`.env`, `.key`, `.pem`, `.pfx`, `.p12`)
+
+If these checks pass, `apply` performs the simulated write (appending comments for `.rs` and `.md` mock operations to avoid compilation/parsing issues) and triggers all `validation_commands` listed in the proposal.
