The scope is bounded (no blockers for Phase 2 implementation). + +### Stage 2: Draft ADR 0003 (Writing Task) + +Write `docs/adr/0003-profile-rule-expression-policy.md` using the format +established by ADRs 0001 and 0002. The ADR must contain: + +- **Status:** Proposed (not Accepted until team approves). +- **Decision:** Named rule weights for v1.0. Profiles consist of rule names, + severity levels, and named parameters. Arbitrary expressions are not + supported. v1.1 may add an optional expression-based rule type, designed in + v1.0 to ensure backward compatibility. +- **Context:** Justification grounded in the research (security, performance, + auditability, alignment with production tools). +- **Consequences:** Positive consequences (simplicity, safety, IDE support via + JSON Schema). Negative consequences (user workflows that require complex + boolean logic must wait for v1.1). Neutral consequences (migration path from + v1.0 to v1.1 is clear). +- **v1.1 Architecture Sketch (Appendix A):** Concrete example showing how a + v1.0 profile remains valid when v1.1 adds expressions. +- **Profile Schema Example (Appendix B):** A complete, annotated profile JSON + showing one of each rule type (simple on/off, with parameters, with severity + override).

Today, new users face a steep discovery curve: the README provides only a bare table listing actions with no guidance on which ones to use, how they fit together, or how to compose them into working workflows. Individual action READMEs exist but are isolated reference docs showing single-action usage patterns, not realistic end-to-end pipelines. + +This ExecPlan will deliver `docs/quickstart.md`, a scenario-driven onboarding guide that bridges the gap between the action table and deep reference documentation. After following this guide, a user new to shared-actions will be able to: + +1. Understand what these actions do and which ones solve their problem (within 5 minutes of reading) +2. See a complete, runnable workflow example for their use case (Rust build+release, Python PyPI publish, coverage measurement, or Dependabot auto-merge) +3. Know how to customize the example for their project and where to find deeper docs +4. Understand common pitfalls and security considerations when using GitHub Actions + +The guide will be validated by running all provided YAML examples through the project's existing action-validator tool and composability smoke tests to ensure they produce expected outputs and work end-to-end. + + +## Constraints + +Hard invariants that must hold throughout implementation. + +- **Scope:** The guide must remain a quickstart (max 1,200 lines including YAML examples). Complex topics (Cargo configuration, nFPM templating, platform-specific cross-compilation) link to existing deep-dive documentation rather than being explained in full. + +- **Content source:** Every action mentioned in the guide already exists in this repository. No new actions are created as part of this task. All examples derive from or are validated against existing action tests and documented workflows (`.github/workflows/ci.yml`, test fixtures). + +- **Linking over duplication:** When explaining concepts (composite actions, reusable workflows, caching, GitHub token permissions), link to existing reference docs (AGENTS.md, developers-guide.md, individual action READMEs) rather than duplicating explanation. + +- **Single source of truth:** The master table of actions remains in the root README.md. The quickstart guide adds narrative and examples but does not replace that table. + +- **Action versioning:** Examples use published major-version tags for remote usage (e.g., `owner/shared-actions/.github/actions/setup-rust@v1`) and local-path syntax for development (`./.github/actions/setup-rust`). Examples must match the current semantic versioning strategy documented in AGENTS.md. + +- **Platform coverage:** Examples must be valid YAML and runnable on at least ubuntu-latest. Platform-specific gotchas (Windows GUI tools, macOS cross-compilation, Linux systemd services) must be explicitly noted or omitted. + +- **No breaking changes:** Implementing this guide must not require changes to existing actions, workflows, or tooling. If such changes are discovered to be necessary, stop and escalate. + + +## Tolerances (exception triggers) + +Thresholds that trigger escalation when breached. + +- **Scope creep:** If the guide grows beyond 1,200 lines (excluding code examples) or requires adding more than 4 complete YAML scenario examples, stop and escalate. + +- **Example validation failure:** If any provided YAML example fails `action-validator` or would fail on a representative CI runner (ubuntu-latest), stop with error logs and escalate. + +- **Design inconsistencies:** If writing examples reveals that following the guide's recommended action sequence would fail at runtime on a specific OS or with specific inputs (even if no documentation contradiction exists), file an issue with a minimal reproduction and escalate. Do not work around the inconsistency with undocumented workarounds. + +- **Documentation conflicts:** If two action READMEs contradict each other (e.g., conflicting input defaults, incompatible output formats), file a GitHub issue and escalate rather than proceeding. + +- **Ambiguous target audience:** If it becomes unclear whether the guide should prioritize Rust users, Python users, or equal coverage, escalate. The current decision is: Rust-primary, with Python as a secondary example, since shared-actions is primarily a Rust tooling library. + +- **Missing testing infrastructure:** If the guide requires inventing new test fixtures, CI workflows, or smoke-test infrastructure not already present in the repository, escalate. + +- **Scope definition:** The quickstart will include full, runnable YAML examples for exactly these actions: (1) `setup-rust`, (2) `rust-build-release`, (3) one platform packager (`linux-packages` preferred), (4) `release-to-pypi-uv`. All other actions receive 1-line descriptions + links to individual READMEs. Deviations from this list trigger scope-creep escalation. + + +## Risks + +Known uncertainties that might affect the plan. + +- **Risk:** Examples become stale as actions evolve. + Severity: high + Likelihood: high + Mitigation: Cross-reference each example against corresponding `action.yml` files. Add comments pinpointing exact input versions. Include a validation date in the guide (e.g., "validated against shared-actions v1.2.3, 2026-06-18"). Establish a quarterly review cadence to refresh examples against the latest action defaults. + +- **Risk:** Action interdependencies are more complex than documented. + Severity: high + Likelihood: high + Mitigation: Before writing examples, create a dependency matrix distinguishing: (a) always-required (e.g., `setup-rust` before compilation), (b) conditionally-required (e.g., `linux-packages` only for release builds), (c) optional (e.g., coverage generation). Document this matrix upfront in the guide to set correct expectations. + +- **Risk:** Examples work on ubuntu-latest but fail on macOS or Windows runners. + Severity: medium + Likelihood: medium + Mitigation: Validate Rust examples on ubuntu-latest and macos-latest if feasible. For platform-specific actions (e.g., `windows-package`), test locally or note the limitation. Clearly annotate platform-specific sections in the guide. + +- **Risk:** First-time users are confused by the difference between actions (reusable steps) and reusable workflows (full workflow files). + Severity: medium + Likelihood: medium + Mitigation: Include a brief comparison section early in the guide. Link to existing doc: docs/composite-actions-vs-full-workflows.md. + +- **Risk:** Users skip the quickstart and go directly to individual action READMEs, missing the narrative context. + Severity: low + Likelihood: medium + Mitigation: Add a prominent "Start here" link in the root README.md pointing to the new quickstart. + +- **Risk:** Glossary terms are unfamiliar to GitHub Actions newcomers. + Severity: low + Likelihood: medium + Mitigation: Include a "Glossary" section at the end of the guide.

A new user can read the quickstart in ≤10 minutes and understand: what these actions do, which ones solve their problem, how to use a chosen action in their workflow. +2. At least one complete Rust example (setup-rust → rust-build-release → linux-packages → release asset upload) is provided and validated. +3. At least one Python example (release-to-pypi-uv) is provided and validated. +4. All YAML examples pass `make lint` (action-validator). +5. All internal doc links are correct. +6. A peer reviewer unfamiliar with shared-actions can follow the guide without external context. + + +## Plan of work + +The work consists of five sequential phases. Each phase has defined go/no-go validation before proceeding to the next. + +### Phase 1: Research & Scope Clarification (2 hours) + +**Goal:** Resolve the 6 gaps identified in expert review before writing begins. + +**Steps:** + +1. Create a dependency matrix distinguishing: + - Always-required actions (e.g., setup-rust before rust-build-release) + - Conditionally-required actions (e.g., linux-packages only for release builds with packaging) + - Optional actions (e.g., generate-coverage can run independently) + + Document this matrix in a plaintext file (e.g., `docs/execplans/6-2-1-dependency-matrix.txt`) so it's visible during implementation. + +2. Finalize the 4-action scope: setup-rust, rust-build-release, linux-packages, release-to-pypi-uv. Confirm this list aligns with the author's intent. If not, escalate. + +3. Decide on file location and hierarchy. File will be `docs/quickstart.md`. Confirm this path and update this execplan if different. + +4. Identify maintenance owner (a person or team responsible for quarterly review and updates). Document in execplan Outcomes section once identified. + +5. Review the four scenarios and their representative use cases: + - Scenario A (Rust build + release): for maintainers releasing Rust binaries + - Scenario B (Python PyPI): for maintainers publishing Python packages + - Scenario C (Coverage): for any project measuring code coverage + - Scenario D (Dependabot auto-merge): for any project using Dependabot + +**Go/no-go gate:** + +- All 5 items above are completed and documented. +- Author confirms the scope and 4-action list. +- If any item is ambiguous, escalate for clarification before proceeding to Phase 2. + +**Artifacts:** dependency-matrix.txt, updated execplan Decision Log. + +--- + +### Phase 2: Outline & Structure (2 hours) + +**Goal:** Draft the guide structure without writing full prose, ensuring coverage and flow. + +**Steps:** + +1. Create a detailed outline of all sections: + - Hero section (1-liner, audience, key features) + - Prerequisites (GitHub Actions knowledge, repo setup) + - What's Inside (category overview, action selector) + - Scenario A outline (Rust build + release) + - Scenario B outline (Python PyPI) + - Scenario C outline (Coverage) + - Scenario D outline (Dependabot auto-merge) + - Understanding Action Dependencies (matrix summary) + - Common Patterns (matrix builds, conditional steps, caching) + - Troubleshooting (3–5 common issues) + - Next Steps (links to deeper docs) + - Glossary (5–8 key terms) + +2. For each scenario, identify: + - The exact actions to show (which of the 4 core actions apply) + - The YAML file path and snippet to provide + - Links to existing docs that provide deeper explanation + - Expected output or success criteria + +3. Create a spreadsheet mapping: + - Use case → Actions involved → Individual README links → Where in guide + +4. Identify all internal doc links (AGENTS.md, developers-guide.md, individual action READMEs, etc.) and verify they exist. + +5. Draft section headers and sub-headers in a skeleton .md file. + +**Go/no-go gate:** + +- Outline is complete with all sections clearly named. +- All internal doc links are verified to exist. +- The 4-action scope is reflected consistently in the outline. +- Author reviews outline and confirms structure. + +**Artifacts:** Skeleton `docs/quickstart.md` with headers only; spreadsheet of action mappings. + +--- + +### Phase 3: Content Creation (4–5 hours) + +**Goal:** Write all narrative and code sections, validating YAML syntax as you go. + +**Steps:** + +1. **Hero & Prerequisites section** (30 min): + - Write 1-line description: "Reusable GitHub Actions for Rust and Python projects." + - Explain who this guide is for. + - List 3–4 key features (build, test, package, release). + - Explain prerequisites (GitHub Actions familiarity, .github/workflows/ directory structure). + +2. **What's Inside section** (30 min): + - Provide a category-based overview (Build, Test, Package, Release, Utilities). + - Create a small table mapping categories to representative actions. + - Add a decision tree: "Are you building Rust, Python, or both? → Go to Scenario A/B/C/D." + +3. **Scenario A: Rust Binary Build + Release** (60 min): + - Write prose explaining the use case. + - Provide a minimal workflow.yml YAML snippet (checkout → setup-rust → rust-build-release → linux-packages → upload-release-assets). + - Annotate the YAML with comments explaining each step. + - Show typical input values and how to customize. + - Explain the output (staging directory, release assets). + - Link to individual action READMEs for deeper customization. + - **Validation**: Run this YAML through `make lint` (action-validator) and verify it passes. + +4. **Scenario B: Python Package to PyPI** (30 min): + - Write prose explaining the use case. + - Provide a minimal workflow.yml snippet (checkout → release-to-pypi-uv). + - Annotate with comments. + - Explain how to set up PyPI credentials/token. + - Link to action README and external PyPI docs. + - **Validation**: Run YAML through `make lint` and verify it passes. + +5. **Scenario C: Coverage Measurement** (30 min): + - Explain the use case (measure code coverage across Rust and Python). + - Provide a workflow snippet showing generate-coverage with lang=rust and lang=python in separate jobs. + - Link to docs/generate-coverage-design.md for deep dive. + - **Validation**: Run YAML through `make lint`. + +6. **Scenario D: Dependabot Auto-Merge** (20 min): + - Explain the reusable workflow pattern. + - Show how to reference the workflow in a user's repository. + - Link to docs/composite-actions-vs-full-workflows.md and the dependabot-automerge.yml workflow file. + - No new YAML needed (workflow already exists in repo). + +7. **Understanding Action Dependencies section** (20 min): + - Present the dependency matrix in prose form (not a table; use bullet points). + - Example: "setup-rust must run before rust-build-release, but is optional if your runner already has Rust installed." + - Explain sequencing rules and when actions can run in parallel. + - Reference the matrix created in Phase 1. + +8. **Common Patterns section** (20 min): + - Show: local vs remote usage (`./.github/actions/setup-rust` vs `owner/shared-actions/.github/actions/setup-rust@v1`). + - Show: matrix builds across platforms. + - Show: conditional step execution. + - Link to developers-guide.md for caching details. + - **Note:** Keep these as brief examples; deeper guidance lives in linked docs. + +9. **Troubleshooting section** (20 min): + - Provide 3–5 common issues and resolutions: + 1. "My build failed in the action but worked locally" → Explain runner differences, link to act documentation. + 2. "How do I debug an action step?" → Explain GitHub Actions debug logs and ACTIONS_STEP_DEBUG. + 3.

The design supports both compile-time alias declaration (via procedural derive macros) and runtime alias registration, with a clear precedence model that respects canonical names over aliases. This feature enables smoother migration for projects like vk and podbot that need to support legacy variable names while standardizing on canonical ones. + +## Motivation + +### Use Case: vk + +The vk project maintains configuration across multiple deployment environments. As vk evolves, environment variable naming conventions may change or consolidate. For example: + +- Old convention: `VK_DATABASE_HOST`, `VK_DB_HOST` (inconsistent naming) +- New convention: `VK_DATABASE_HOST` (single canonical name) + +Without alias support, vk must either: +1. Hardcode checks for multiple variable names throughout the codebase, creating maintenance burden +2. Perform manual pre-processing of environment variables at startup +3. Maintain two parallel configuration systems indefinitely + +With aliases, vk can declare `VK_DB_HOST` as an alias for `VK_DATABASE_HOST`, automatically falling back to the old name when the canonical name is unset. This enables gradual migration without code duplication. + +### Use Case: podbot + +Podbot integrates ortho-config for multi-tenant audio processing configuration. As the platform matures: + +- Original var names used underscores: `PODBOT_AUDIO_SAMPLE_RATE_HZ` +- Standardization effort switches to kebab-case in configuration: `podbot.audio.sample-rate-hz` +- Internal library names differ from external configuration names + +Aliases allow podbot to: +1. Define the production canonical name in configuration +2. Declare aliases for legacy environment variables, documentation names, and integration points +3. Support multiple deployment scenarios (legacy CI/CD, containers, Kubernetes) without code changes + +### Core Problem + +Both projects face this pattern: environment-first systems need to support **backward compatibility** while **migrating to new naming schemes**. Current solutions are ad-hoc and spread throughout application code.

This allows ortho-config to own the generic mechanics +while applications own policy choices (names, env-var spelling, scope ordering). + +## Motivation + +### Use Case: netsuke + +netsuke maintains configuration discovery with a nuanced four-layer policy +currently implemented in local code (`src/cli/discovery.rs`): + +1. **Explicit selection order**: `--config > NETSUKE_CONFIG > NETSUKE_CONFIG_PATH + > automatic discovery` +2. **Fail-closed semantics**: Missing or malformed selected file stops discovery + immediately (no fallback to automatic discovery) +3. **Project-over-user stacking**: Both user-scope and project-scope config load, + with project config keys overriding user keys while preserving user-only keys +4. **Early resolution for diagnostic**: File layers must be available before full + merge to extract `diag_json` and affect startup/merge error reporting + +Today, netsuke cannot express these patterns using ortho-config's `compose_layers()` +API alone. Instead, netsuke must: + +- Duplicate selector precedence logic in `collect_diag_file_layers(cli)` +- Manually orchestrate file loading and error handling +- Maintain custom path resolution that bypasses ortho-config's discovery +- Rebuild the selection chain during the merge pass, losing early diagnostics + +### Broader Problem + +Other applications with complex config discovery (Kubernetes, Docker Compose, +systemd, Poetry) all solve the same problem independently: expressing ordered +selection, multi-scope stacking, and explicit error handling without +reimplementing discovery mechanics.

The plan covers: - Threat model documentation (symlink escapes, path traversal, privilege escalation) - Path canonicalization with symlink detection - Allowlist enforcement for mount roots - Write permission validation in rootless engine scenarios - Integration and end-to-end testing via BDD - Documentation updates The implementation proceeds through seven phases with clear Red-Green-Refactor milestones for unit tests and BDD scenarios. All code changes maintain existing API stability while adding new workspace mount validation capabilities.

The sections `Constraints`, `Tolerances`, `Risks`, `Progress`, `Surprises & Discoveries`, `Decision Log`, and `Outcomes & Retrospective` must be kept up to date as work proceeds. + +Status: DRAFT + + +## Purpose / big picture + +Podbot normalizes every container launch into typed request and plan values, creating a shared control plane for interactive sessions, hosted protocols, MCP wires, and orchestration surfaces. This milestone implements safe host-mounted workspaces—the mechanism by which operators can mount host directories into container sessions while maintaining strict boundaries against symlink escapes, unauthorized path access, and privilege escalation vectors. + +After this change, users will be able to configure host-mounted workspaces with confidence that: + +1. All mount paths are canonicalized; symlinks and path traversal attacks are rejected +2. Mounts are confined to an allowlisted set of root directories configured by the operator +3. Write permissions are validated before mounting (accounting for rootless-engine scenarios) +4. The threat model and security boundary are documented clearly +5. Negative coverage tests prove forbidden paths are rejected even under adversarial conditions + +Operators enable this by configuring workspace mount roots in Podbot's configuration, then specifying workspace paths during launch. The system validates paths against the allowlist, canonicalizes them, and rejects any attempt to escape the allowlisted roots. A new section in `docs/users-guide.md` documents threat boundaries and safe usage patterns. + + +## Constraints + +Hard invariants that must hold throughout implementation. + +- **No public API changes**: The workspace launch interface must remain stable. If a new type or function is required, it must not change existing function signatures or trait interfaces in the launching code path. +- **No new external dependencies without approval**: The implementation must use Rust stable library crates. If `path-security`, `soft-canonicalize`, or similar crates are required, document the decision in the Decision Log and escalate. +- **Rootless engine compatibility**: The implementation must work correctly in both rootless podman and Docker environments. The permission validation logic must account for user namespace remapping (UID/GID shifts). +- **Backward compatibility**: Existing workspace configurations without explicit mount roots must continue to work. If a migration is needed, it must be invisible to operators (auto-populated from safe defaults). +- **No symlinks in the validated set**: After canonicalization, if a mount path contains a symlink in any component, it must be rejected. This prevents time-of-check-time-of-use (TOCTOU) races and symlink-exchange attacks. + + +## Tolerances (exception triggers) + +Thresholds that trigger escalation when breached. + +- **Scope**: If implementation requires changes to more than 15 files or more than 2000 net lines of code added, stop and escalate. +- **Dependencies**: If a new external dependency (crate) is required beyond Rust stdlib, stop and escalate with rationale. +- **Interface changes**: If existing public function signatures in the workspace launch path must change, stop and escalate with justification. +- **Test coverage**: If unit test coverage for canonicalization and allowlist validation falls below 90%, stop and rework tests before proceeding. +- **Iterations**: If the same test fails more than 3 consecutive times after fixes, stop and escalate with root-cause analysis. +- **Design decisions**: If the threat model or security boundary interpretation differs from the plan, document in Decision Log and escalate for approval. + + +## Risks + +Known uncertainties that might affect the plan. Each risk includes severity, likelihood, and mitigation. + +- **Risk**: TOCTOU races between canonicalization and mount time. An attacker could replace a validated path with a symlink between validation and actual mount invocation. + **Severity**: High + **Likelihood**: Medium + **Mitigation**: Use `O_NOFOLLOW` flag and atomic operations (`openat2` with `RESOLVE_IN_ROOT` when available). Validate that no code path leaves a window between checks and mount. Include explicit TOCTOU test cases. + +- **Risk**: User namespace remapping makes permission checks unreliable in rootless scenarios. A path writable by the rootless engine may not be writable by the container's remapped UIDs. + **Severity**: High + **Likelihood**: Medium + **Mitigation**: Test permission validation in both rootless and root-privileged environments. Use `podman unshare` to validate permissions in the correct namespace. Document the UID/GID remapping assumptions in the threat model. + +- **Risk**: Symlink cycles or deeply nested symlinks could cause denial-of-service or resource exhaustion during canonicalization. + **Severity**: Medium + **Likelihood**: Low + **Mitigation**: Implement symlink cycle detection. Limit canonicalization depth (e.g., max 40 components). Return clear error messages on depth exceeded. + +- **Risk**: The allowlist configuration format may be ambiguous or error-prone. Operators could misconfigure roots and accidentally deny legitimate mounts or allow unintended paths. + **Severity**: Medium + **Likelihood**: Low + **Mitigation**: Use structured configuration (YAML/TOML, not free-form strings). Validate configuration at startup and report errors. Include examples and warnings in documentation. + +- **Risk**: Interactions with different mount flags (`bind`, `rbind`, `nosuid`, `noexec`, etc.) may expose mount escape vectors not anticipated in the threat model. + **Severity**: Medium + **Likelihood**: Low + **Mitigation**: Document which mount flags are safe and which are dangerous. Validate mount options against a safe list. Reference CVE-2025 series runc vulnerabilities to ensure mitigations are specific. + + +## Progress + +Use a list with checkboxes to track granular steps.

This section is updated as work proceeds. + +(None yet; will be populated during implementation.) + + +## Decision log + +Record every significant decision made while working on the plan. + +- **Decision**: Use Rust `std::fs::canonicalize()` as the baseline for path normalization, with additional checks for symlink presence in the canonical path. + **Rationale**: Rust stdlib is stable and audited. If symlinks are present after canonicalization, it indicates a TOCTOU issue or misconfiguration that should be rejected. This avoids introducing external path-security crates unless we encounter a genuine limitation. + **Date/Author**: 2026-06-18 (planning phase). + +- **Decision**: Allowlist roots are configured in Podbot configuration (YAML) at startup, not per-request. + **Rationale**: This enforces operator control and prevents operators from accidentally allowing arbitrary mounts. Operators must explicitly configure safe roots; Podbot cannot infer them dynamically. Configuration errors are detected at startup, not at mount time. + **Date/Author**: 2026-06-18 (planning phase). + +- **Decision**: Permission validation will use `podman unshare` in rootless scenarios to test permissions in the container's namespace. + **Rationale**: UID/GID remapping in rootless engines makes naive permission checks unreliable. Testing in the actual namespace where the mount will occur is the only reliable method. + **Date/Author**: 2026-06-18 (planning phase). + +(Additional decisions will be recorded during implementation.) + + +## Outcomes & retrospective + +This section is populated at major milestones and at completion. + +(To be updated as work proceeds.) + + +## Context and orientation + +### Current state + +Podbot is a Rust project organized around composing container launches from reusable request/plan primitives. The codebase currently lacks specialized workspace mount validation. Related infrastructure exists: + +- **Existing cargo utilities** (`cargo_utils.py`): Workspace root discovery by walking up the directory tree looking for `Cargo.toml` with `[workspace]` table. +- **Existing mount inspection** (`validate_cli.py`): Mount filesystem type and executable-store detection via `/proc/self/mountinfo`. +- **Existing sandbox infrastructure** (`validate_polythene.py`): Context manager pattern for managing container sessions with configurable isolation strategies. + +The implementation will add a new module, `workspace_mounts`, with three core functions: + +1. `canonicalize_workspace_path(path: &Path) -> Result` — Validate and canonicalize a proposed mount path. +2. `enforce_allowlist(canonical_path: &Path, allowed_roots: &[PathBuf]) -> Result<(), Error>` — Verify the path is within the allowlisted roots. +3. `validate_mount_permissions(path: &Path, container_uid: u32, container_gid: u32) -> Result<(), Error>` — Ensure the path is writable by the container. + +### Key files and modules + +- `src/workspace_mounts.rs` — New module for path validation and allowlist enforcement. +- `src/config.rs` (existing) — To be extended with `WorkspaceMountConfig` struct. +- `tests/workspace_mounts_tests.rs` — Unit tests for all three functions. +- `tests/bdd/workspace_mounts.feature` (new) — BDD scenarios for happy and unhappy paths. +- `docs/users-guide.md` — To add section on configuring and using host-mounted workspaces. +- `docs/developers-guide.md` — To add component architecture section for workspace mounts. + + +## Plan of work + +The implementation proceeds through seven stages, each with clear go/no-go validation points. All code changes follow Red-Green-Refactor: add a failing test, implement the minimal fix, then refactor. + +### Stage A: Design & threat model documentation + +Before writing code, document the threat model and design decisions. + +1. Create a new document `docs/adr/ADR-0003-host-mounted-workspace-security.md` (or use the component architecture section of developers-guide.md). +2. Document the following threat model sections: + - **Attacks prevented**: Symlink escapes (including symlink-exchange), path traversal, UID 0 escalation via mount options. + - **Attacks out-of-scope**: Attacks that exploit kernel bugs in the container runtime itself (e.g., CVE-2025 runc vulnerabilities). Mitigation is to keep runc and podman patched. + - **Assumptions**: Operator correctly configures allowlisted roots. Filesystem is ext4/tmpfs/overlayfs (no btrfs reflexivity). Container UID/GID mapping is correct. + +3. Define the configuration schema for allowlisted roots. Example: + ```yaml + workspace_mounts: + allowed_roots: + - /tmp/workspaces + - /home/ci/work + safe_defaults: + - /tmp + ``` + +4. Write validation criteria: "The threat model document clearly identifies attack vectors, assumptions, and out-of-scope cases. Configuration schema is unambiguous." + +**Validation**: Review threat model doc and configuration schema. Escalate if any attack vector is unclear or assumptions are unrealistic. + +### Stage B: Core path canonicalization + +Implement path canonicalization and symlink detection as the foundation. + +#### Red phase (failing tests) + +1. Create `tests/workspace_mounts_tests.rs` with the following test cases: + ``` + - test_canonicalize_simple_path: /tmp/work → /tmp/work (no symlinks, no .. or .) + - test_canonicalize_with_dotdot: /tmp/work/../work → /tmp/work + - test_canonicalize_with_dot: /tmp/work/. → /tmp/work + - test_canonicalize_symlink_in_path: /tmp/link_to_work/file (where link_to_work → work) → ERROR + - test_canonicalize_symlink_chain: /tmp/a/b/c where b → ../other/path → ERROR + - test_canonicalize_nonexistent_path: /tmp/nonexistent/dir → ERROR (or allow if soft-canonicalization) + - test_canonicalize_cycle: /tmp/a → /tmp/a → ERROR (symlink cycle detection) + - test_canonicalize_deep_nesting: path with 50+ components → ERROR (DoS prevention) + ``` + +2. Run tests; expect all to fail with "function not found" or similar. + +#### Green phase (minimal implementation) + +1. Create `src/workspace_mounts.rs`: + ```rust + use std::fs; + use std::path::{Path, PathBuf}; + + #[derive(Debug)] + pub enum WorkspaceMountError { + SymlinkDetected(PathBuf), + SymlinkCycle(PathBuf), + DepthExceeded, + PermissionDenied, + NotFound, + } + + pub fn canonicalize_workspace_path(path: &Path) -> Result { + let canonical = fs::canonicalize(path) + .map_err(|e| match e.kind() { + std::io::ErrorKind::NotFound => WorkspaceMountError::NotFound, + std::io::ErrorKind::PermissionDenied => WorkspaceMountError::PermissionDenied, + _ => WorkspaceMountError::NotFound, + })?; + + // Check for symlinks in the canonical path by comparing readlink results. + // If any component resolves via symlink, reject. + validate_no_symlinks(&canonical)?; + + Ok(canonical) + } + + fn validate_no_symlinks(path: &Path) -> Result<(), WorkspaceMountError> { + let mut components = path.components(); + let mut current = PathBuf::from("/"); + let mut depth = 0; + const MAX_DEPTH: usize = 40; + + while let Some(component) = components.next() { + depth += 1; + if depth > MAX_DEPTH { + return Err(WorkspaceMountError::DepthExceeded); + } + + current.push(component); + + // If reading the link succeeds, a symlink exists. + if fs::read_link(¤t).is_ok() { + return Err(WorkspaceMountError::SymlinkDetected(current.clone())); + } + } + + Ok(()) + } + ``` + +2. Run the failing tests; they should now pass or fail for the expected reasons (e.g., "SymlinkDetected" for symlink tests). + +#### Refactor phase + +1. Improve error handling to match test expectations exactly. +2. Add better error messages (include path in error variant). +3. Run tests again; all should pass. +4. Run `make test` to confirm no regressions. + +### Stage C: Allowlist enforcement + +Implement allowlist membership checking. + +#### Red phase + +1. Add tests to `tests/workspace_mounts_tests.rs`: + ``` + - test_enforce_allowlist_within_root: /tmp/workspaces/job123 against [/tmp/workspaces] → OK + - test_enforce_allowlist_outside_root: /var/work against [/tmp/workspaces] → ERROR + - test_enforce_allowlist_escape_attempt: /tmp/workspaces/../../../etc against [/tmp/workspaces] → ERROR + - test_enforce_allowlist_multiple_roots: /home/ci/job against [/tmp, /home/ci] → OK + - test_enforce_allowlist_empty_roots: /tmp/work against [] → ERROR + - test_enforce_allowlist_prefix_attack: /tmp/workspaces_other against [/tmp/workspaces] → ERROR (name-based bypass) + ``` + +2. Run tests; expect failures. + +#### Green phase + +1. Add to `src/workspace_mounts.rs`: + ```rust + pub fn enforce_allowlist( + canonical_path: &Path, + allowed_roots: &[PathBuf], + ) -> Result<(), WorkspaceMountError> { + if allowed_roots.is_empty() { + return Err(WorkspaceMountError::NoAllowedRoots); + } + + for root in allowed_roots { + // Check if path starts with root and the next component is a separator or end-of-path. + if canonical_path.starts_with(root) { + // Prevent "/tmp/workspaces_other" from matching "/tmp/workspaces". + if canonical_path.parent() == Some(root) || root.parent().map_or(false, |p| canonical_path.starts_with(p)) { + return Ok(()); + } + } + } + + Err(WorkspaceMountError::NotInAllowlist(canonical_path.to_path_buf())) + } + ``` + +2. Run tests; refine error handling until all pass. + +#### Refactor + +1. Extract path prefix-checking logic into a helper function. +2. Run tests again; all should pass. +3. Run `make test`. + +### Stage D: Permission validation + +Implement write-permission checking with rootless-engine support. + +#### Red phase + +1. Add tests: + ``` + - test_validate_permissions_writable_dir: /tmp/writable (mode 0755) → OK + - test_validate_permissions_read_only_dir: /tmp/readonly (mode 0555) → ERROR + - test_validate_permissions_nonexistent_dir: /tmp/nonexistent → ERROR + - test_validate_permissions_rootless_namespace_check: (in rootless podman context) → OK + - test_validate_permissions_permission_denied: /root/private (not accessible) → ERROR + ``` + +2. For rootless tests, use `testcontainers-rs` with a rootless podman fixture. (Skippable if podman not available.) + +3. Run tests; expect failures. + +#### Green phase + +1. Add to `src/workspace_mounts.rs`: + ```rust + pub fn validate_mount_permissions( + path: &Path, + container_uid: u32, + container_gid: u32, + ) -> Result<(), WorkspaceMountError> { + let metadata = fs::metadata(path) + .map_err(|e| match e.kind() { + std::io::ErrorKind::NotFound => WorkspaceMountError::NotFound, + std::io::ErrorKind::PermissionDenied => WorkspaceMountError::PermissionDenied, + _ => WorkspaceMountError::PermissionDenied, + })?; + + if !metadata.is_dir() { + return Err(WorkspaceMountError::NotADirectory); + } + + // Check write bit for owner. + let mode = metadata.permissions().mode(); + if (mode & 0o200) == 0 { + return Err(WorkspaceMountError::NotWritable); + } + + Ok(()) + } + ``` + +2. Run tests. For rootless scenarios, tests may need conditional logic (skipped on non-rootless systems, run with `podman unshare` on rootless). + +#### Refactor + +1. Extract permission-checking logic and add more nuanced checks (owner vs. group vs. other). +2. Run tests; all should pass. +3. Run `make test`. + +### Stage E: Integration and edge cases + +Integrate the three functions and test end-to-end behaviors with BDD. + +#### Red phase (BDD scenarios) + +1.

If a new type or function is required, it must not change existing function signatures or trait interfaces in the launching code path. -- **No new external dependencies without approval**: The implementation must use Rust stable library crates. If `path-security`, `soft-canonicalize`, or similar crates are required, document the decision in the Decision Log and escalate. -- **Rootless engine compatibility**: The implementation must work correctly in both rootless podman and Docker environments. The permission validation logic must account for user namespace remapping (UID/GID shifts). -- **Backward compatibility**: Existing workspace configurations without explicit mount roots must continue to work. If a migration is needed, it must be invisible to operators (auto-populated from safe defaults). -- **No symlinks in the validated set**: After canonicalization, if a mount path contains a symlink in any component, it must be rejected. This prevents time-of-check-time-of-use (TOCTOU) races and symlink-exchange attacks. - +- No public API changes in the workspace launch interface +- No new external dependencies without approval +- Rootless engine compatibility (podman, Docker) +- Backward compatibility with existing workspace configurations +- No symlinks in the validated set after canonicalization ## Tolerances (exception triggers) Thresholds that trigger escalation when breached. -- **Scope**: If implementation requires changes to more than 15 files or more than 2000 net lines of code added, stop and escalate. -- **Dependencies**: If a new external dependency (crate) is required beyond Rust stdlib, stop and escalate with rationale. -- **Interface changes**: If existing public function signatures in the workspace launch path must change, stop and escalate with justification. -- **Test coverage**: If unit test coverage for canonicalization and allowlist validation falls below 90%, stop and rework tests before proceeding. -- **Iterations**: If the same test fails more than 3 consecutive times after fixes, stop and escalate with root-cause analysis. -- **Design decisions**: If the threat model or security boundary interpretation differs from the plan, document in Decision Log and escalate for approval. - +- Scope: ≤15 files or ≤2000 net lines of code added +- Dependencies: No new crates without escalation +- Interface changes: Stop if existing signatures must change +- Test coverage: ≥90% for canonicalization and allowlist validation +- Iterations: Stop if same test fails 3+ consecutive times +- Design decisions: Escalate if threat model interpretation differs ## Risks -Known uncertainties that might affect the plan. Each risk includes severity, likelihood, and mitigation. - -- **Risk**: TOCTOU races between canonicalization and mount time. An attacker could replace a validated path with a symlink between validation and actual mount invocation. - **Severity**: High - **Likelihood**: Medium - **Mitigation**: Use `O_NOFOLLOW` flag and atomic operations (`openat2` with `RESOLVE_IN_ROOT` when available). Validate that no code path leaves a window between checks and mount. Include explicit TOCTOU test cases. - -- **Risk**: User namespace remapping makes permission checks unreliable in rootless scenarios. A path writable by the rootless engine may not be writable by the container's remapped UIDs. - **Severity**: High - **Likelihood**: Medium - **Mitigation**: Test permission validation in both rootless and root-privileged environments. Use `podman unshare` to validate permissions in the correct namespace. Document the UID/GID remapping assumptions in the threat model. - -- **Risk**: Symlink cycles or deeply nested symlinks could cause denial-of-service or resource exhaustion during canonicalization. - **Severity**: Medium - **Likelihood**: Low - **Mitigation**: Implement symlink cycle detection. Limit canonicalization depth (e.g., max 40 components). Return clear error messages on depth exceeded. - -- **Risk**: The allowlist configuration format may be ambiguous or error-prone. Operators could misconfigure roots and accidentally deny legitimate mounts or allow unintended paths. - **Severity**: Medium - **Likelihood**: Low - **Mitigation**: Use structured configuration (YAML/TOML, not free-form strings). Validate configuration at startup and report errors. Include examples and warnings in documentation. - -- **Risk**: Interactions with different mount flags (`bind`, `rbind`, `nosuid`, `noexec`, etc.) may expose mount escape vectors not anticipated in the threat model. - **Severity**: Medium - **Likelihood**: Low - **Mitigation**: Document which mount flags are safe and which are dangerous. Validate mount options against a safe list.

Create `tests/workspace_mounts_tests.rs` with the following test cases: - ``` - - test_canonicalize_simple_path: /tmp/work → /tmp/work (no symlinks, no .. or .) - - test_canonicalize_with_dotdot: /tmp/work/../work → /tmp/work - - test_canonicalize_with_dot: /tmp/work/. → /tmp/work - - test_canonicalize_symlink_in_path: /tmp/link_to_work/file (where link_to_work → work) → ERROR - - test_canonicalize_symlink_chain: /tmp/a/b/c where b → ../other/path → ERROR - - test_canonicalize_nonexistent_path: /tmp/nonexistent/dir → ERROR (or allow if soft-canonicalization) - - test_canonicalize_cycle: /tmp/a → /tmp/a → ERROR (symlink cycle detection) - - test_canonicalize_deep_nesting: path with 50+ components → ERROR (DoS prevention) - ``` - -2. Run tests; expect all to fail with "function not found" or similar. - -#### Green phase (minimal implementation) - -1. Create `src/workspace_mounts.rs`: - ```rust - use std::fs; - use std::path::{Path, PathBuf}; - - #[derive(Debug)] - pub enum WorkspaceMountError { - SymlinkDetected(PathBuf), - SymlinkCycle(PathBuf), - DepthExceeded, - PermissionDenied, - NotFound, - } - - pub fn canonicalize_workspace_path(path: &Path) -> Result { - let canonical = fs::canonicalize(path) - .map_err(|e| match e.kind() { - std::io::ErrorKind::NotFound => WorkspaceMountError::NotFound, - std::io::ErrorKind::PermissionDenied => WorkspaceMountError::PermissionDenied, - _ => WorkspaceMountError::NotFound, - })?; - - // Check for symlinks in the canonical path by comparing readlink results. - // If any component resolves via symlink, reject. - validate_no_symlinks(&canonical)?; - - Ok(canonical) - } - - fn validate_no_symlinks(path: &Path) -> Result<(), WorkspaceMountError> { - let mut components = path.components(); - let mut current = PathBuf::from("/"); - let mut depth = 0; - const MAX_DEPTH: usize = 40; - - while let Some(component) = components.next() { - depth += 1; - if depth > MAX_DEPTH { - return Err(WorkspaceMountError::DepthExceeded); - } - - current.push(component); - - // If reading the link succeeds, a symlink exists. - if fs::read_link(¤t).is_ok() { - return Err(WorkspaceMountError::SymlinkDetected(current.clone())); - } - } - - Ok(()) - } - ``` - -2. Run the failing tests; they should now pass or fail for the expected reasons (e.g., "SymlinkDetected" for symlink tests). - -#### Refactor phase - -1. Improve error handling to match test expectations exactly. -2. Add better error messages (include path in error variant). -3. Run tests again; all should pass. -4. Run `make test` to confirm no regressions. +Implement `canonicalize_workspace_path()` with Red-Green-Refactor: +failing tests, minimal implementation, refactor. ### Stage C: Allowlist enforcement -Implement allowlist membership checking. - -#### Red phase - -1. Add tests to `tests/workspace_mounts_tests.rs`: - ``` - - test_enforce_allowlist_within_root: /tmp/workspaces/job123 against [/tmp/workspaces] → OK - - test_enforce_allowlist_outside_root: /var/work against [/tmp/workspaces] → ERROR - - test_enforce_allowlist_escape_attempt: /tmp/workspaces/../../../etc against [/tmp/workspaces] → ERROR - - test_enforce_allowlist_multiple_roots: /home/ci/job against [/tmp, /home/ci] → OK - - test_enforce_allowlist_empty_roots: /tmp/work against [] → ERROR - - test_enforce_allowlist_prefix_attack: /tmp/workspaces_other against [/tmp/workspaces] → ERROR (name-based bypass) - ``` - -2. Run tests; expect failures. - -#### Green phase - -1. Add to `src/workspace_mounts.rs`: - ```rust - pub fn enforce_allowlist( - canonical_path: &Path, - allowed_roots: &[PathBuf], - ) -> Result<(), WorkspaceMountError> { - if allowed_roots.is_empty() { - return Err(WorkspaceMountError::NoAllowedRoots); - } - - for root in allowed_roots { - // Check if path starts with root and the next component is a separator or end-of-path. - if canonical_path.starts_with(root) { - // Prevent "/tmp/workspaces_other" from matching "/tmp/workspaces". - if canonical_path.parent() == Some(root) || root.parent().map_or(false, |p| canonical_path.starts_with(p)) { - return Ok(()); - } - } - } - - Err(WorkspaceMountError::NotInAllowlist(canonical_path.to_path_buf())) - } - ``` - -2. Run tests; refine error handling until all pass. - -#### Refactor - -1. Extract path prefix-checking logic into a helper function. -2. Run tests again; all should pass. -3. Run `make test`. +Implement `enforce_allowlist()` with Red-Green-Refactor. ### Stage D: Permission validation -Implement write-permission checking with rootless-engine support. - -#### Red phase - -1. Add tests: - ``` - - test_validate_permissions_writable_dir: /tmp/writable (mode 0755) → OK - - test_validate_permissions_read_only_dir: /tmp/readonly (mode 0555) → ERROR - - test_validate_permissions_nonexistent_dir: /tmp/nonexistent → ERROR - - test_validate_permissions_rootless_namespace_check: (in rootless podman context) → OK - - test_validate_permissions_permission_denied: /root/private (not accessible) → ERROR - ``` - -2. For rootless tests, use `testcontainers-rs` with a rootless podman fixture. (Skippable if podman not available.) - -3. Run tests; expect failures. - -#### Green phase - -1. Add to `src/workspace_mounts.rs`: - ```rust - pub fn validate_mount_permissions( - path: &Path, - container_uid: u32, - container_gid: u32, - ) -> Result<(), WorkspaceMountError> { - let metadata = fs::metadata(path) - .map_err(|e| match e.kind() { - std::io::ErrorKind::NotFound => WorkspaceMountError::NotFound, - std::io::ErrorKind::PermissionDenied => WorkspaceMountError::PermissionDenied, - _ => WorkspaceMountError::PermissionDenied, - })?; - - if !metadata.is_dir() { - return Err(WorkspaceMountError::NotADirectory); - } - - // Check write bit for owner. - let mode = metadata.permissions().mode(); - if (mode & 0o200) == 0 { - return Err(WorkspaceMountError::NotWritable); - } - - Ok(()) - } - ``` - -2. Run tests. For rootless scenarios, tests may need conditional logic (skipped on non-rootless systems, run with `podman unshare` on rootless). - -#### Refactor - -1. Extract permission-checking logic and add more nuanced checks (owner vs. group vs. other). -2. Run tests; all should pass. -3. Run `make test`. +Implement `validate_mount_permissions()` with Red-Green-Refactor +including integration tests with rootless podman. ### Stage E: Integration and edge cases -Integrate the three functions and test end-to-end behaviors with BDD. - -#### Red phase (BDD scenarios) - -1. Create `tests/bdd/workspace_mounts.feature`: - ```gherkin - Feature: Safe host-mounted workspaces - Scenario: Mount a workspace within the allowlist - Given a configured allowed root "/tmp/workspaces" - And a workspace path "/tmp/workspaces/my-job" - When the workspace is mounted - Then the mount succeeds - - Scenario: Reject workspace outside the allowlist - Given a configured allowed root "/tmp/workspaces" - And a workspace path "/var/work" - When the workspace is mounted - Then the mount fails with reason "NotInAllowlist" - - Scenario: Reject symlink escapes - Given a configured allowed root "/tmp/workspaces" - And a symlink at "/tmp/workspaces/link" pointing to "/etc" - When the workspace is mounted to the symlink - Then the mount fails with reason "SymlinkDetected" - - Scenario: Reject paths with symlinks in any component - Given a configured allowed root "/tmp/workspaces" - And a symlink at "/tmp/workspaces/a/b" (where /tmp/workspaces/a is a symlink) - When the workspace is mounted to "/tmp/workspaces/a/b/c" - Then the mount fails with reason "SymlinkDetected" - ``` - -2. Run BDD scenarios; expect failures (steps not implemented). - -#### Green phase - -1. Implement BDD step definitions (using `cucumber` or equivalent BDD framework). -2. Integrate the three functions into a single `mount_workspace()` function: - ```rust - pub fn mount_workspace( - path: &Path, - allowed_roots: &[PathBuf], - container_uid: u32, - container_gid: u32, - ) -> Result { - let canonical = canonicalize_workspace_path(path)?; - enforce_allowlist(&canonical, allowed_roots)?; - validate_mount_permissions(&canonical, container_uid, container_gid)?; - Ok(canonical) - } - ``` - -3. Hook BDD steps to call this function and assert outcomes. - -4. Run BDD scenarios; they should pass. - -#### Refactor - -1. Add snapshot tests for error messages (using `insta` crate). -2. Add property tests (using `proptest`) for path canonicalization: ensure that for any valid path and allowlist, the result is deterministic and doesn't change on repeated calls. -3. Run `make test` and confirm all pass. +Write BDD scenarios and integrate three functions into single +`mount_workspace()` function. Add snapshot and property tests. ### Stage F: Documentation and validation -Document the feature and run all quality gates. - -1. **Update `docs/users-guide.md`**: - - Add section "Configuring Host-Mounted Workspaces" - - Explain the threat model: symlink escapes are prevented, allowlists are enforced, permissions are validated. - - Provide example configuration in YAML. - - Show example command to launch a workspace: `podbot launch --workspace /tmp/workspaces/my-job`. - - Document the error messages and how to interpret them. - -2. **Update `docs/developers-guide.md`**: - - Add section "Workspace Mounts Component Architecture" - - Describe the three-function design and why it's organized that way. - - Explain the threat model assumptions. - - Reference the ADR if one exists. - -3. **Run quality gates**: - ```bash - make check-fmt - make lint - make test - coderabbit review --agent - ``` - -4. **Review and resolve CodeRabbit findings** (described in next milestone). +Update documentation and run quality gates. ### Stage G: Roadmap update and PR -1. Update `docs/podbot-roadmap.md` (or create it if it doesn't exist): - - Mark task 4.2.2 as "done" with completion date. - -2. Push the branch: - ```bash - git push origin 4-2-2-safe-host-mounted-workspaces - ``` - -3. Create a draft PR with the title: - ``` - (4.2.2) Implement safe host-mounted workspaces - ``` - -4. Include in the PR body: - - Summary of what was implemented. - - Threat model summary (symlink escapes prevented, allowlists enforced). - - Link to execplan: `docs/execplans/4-2-2-safe-host-mounted-workspaces.md` - - Link to lody session: `https://lody.ai/leynos/sessions/${LODY_SESSION_ID}` - - -## Concrete steps - -### Initial setup (already completed) - -1.

Update roadmap and push: - ```bash - git add -A - git commit -m "docs: mark 4.2.2 as complete" - git push origin 4-2-2-safe-host-mounted-workspaces - ``` - -2. Get `LODY_SESSION_ID`: - ```bash - echo ${LODY_SESSION_ID} - ``` - -3. Create draft PR with title and lody session link in description. - +Update roadmap marking 4.2.2 as "done" and create draft PR. ## Validation and acceptance ### Acceptance criteria -All of the following must be true at completion: - -1. **Unit tests pass**: `cargo test workspace_mounts --lib` completes with all tests passing. - - Canonicalization tests cover symlinks, cycles, depth limits. - - Allowlist tests cover inclusion, exclusion, prefix attacks. - - Permission tests cover writable, read-only, nonexistent paths. - - Coverage ≥ 90% for `workspace_mounts.rs`. - -2. **BDD scenarios pass**: `cargo test --test bdd_workspace_mounts` completes with all scenarios passing. - - Happy path: valid workspace within allowlist mounts successfully. - - Sad paths: symlinks, out-of-bounds paths, and permission errors are rejected with correct error reasons. - -3. **Integration with configuration**: Configuration struct in `src/config.rs` includes `workspace_mount_roots: Vec`. - - Configuration is validated at startup; invalid roots are reported as errors. - - Default configuration includes `/tmp` as a safe root (if appropriate). - -4. **Documentation is complete**: - - `docs/users-guide.md` includes section on configuring and using host-mounted workspaces. - - `docs/developers-guide.md` includes component architecture section. - - Threat model is documented (in ADR or developers-guide). - -5. **Quality gates pass**: - - `make check-fmt` passes (no formatting issues). - - `make lint` passes (no clippy warnings in new code). - - `make test` passes (all tests, including BDD). - - `coderabbit review --agent` finds no outstanding concerns. - -6. **Roadmap is updated**: - - `docs/podbot-roadmap.md` (if it exists) marks task 4.2.2 as "done". - -7. **PR is created**: - - PR title includes `(4.2.2)` and describes the feature. - - PR description includes execplan link and lody session link. - -### Red-Green-Refactor evidence - -For each major function (`canonicalize_workspace_path`, `enforce_allowlist`, `validate_mount_permissions`): - -1. **Red**: Test fails before implementation. Example output: - ``` - test workspace_mounts::tests::test_canonicalize_simple_path ... FAILED - - thread 'workspace_mounts::tests::test_canonicalize_simple_path' panicked at - 'cannot find path canonicalization implementation' - ``` - -2. **Green**: Minimal implementation makes test pass. Example output: - ``` - test workspace_mounts::tests::test_canonicalize_simple_path ... ok - ``` - -3. **Refactor**: Improve readability, extract helpers, add more tests. All tests still pass: - ``` - test result: ok. 25 passed; 0 failed; 0 ignored; 0 measured - ``` - -### BDD evidence - -1. **Red**: Scenarios fail before integration. Example: - ``` - Scenario: Mount a workspace within the allowlist ... FAILED - Given a configured allowed root "/tmp/workspaces" ... undefined step - ``` - -2. **Green**: Steps are defined and scenarios pass: - ``` - Scenario: Mount a workspace within the allowlist ... PASSED - Scenario: Reject workspace outside the allowlist ... PASSED - Scenario: Reject symlink escapes ... PASSED - Scenario: Reject paths with symlinks in any component ... PASSED - ``` - - -## Idempotence and recovery - -All steps are idempotent: - -- **Code edits** can be repeated without side effects (overwriting the same content). -- **Test runs** do not modify the filesystem (tests use temporary directories via `tempfile` crate). -- **Configuration validation** runs at startup and reports errors clearly (no partial state). - -If a step fails: - -1. Identify the failure (check error message or test output). -2. Fix the root cause (update code or tests). -3. Re-run the step or the entire test suite. -4. Commit the fix as a new commit (not an amendment). - -No rollback is needed; all changes are forward-only. - +1. Unit tests pass with ≥90% coverage +2. BDD scenarios pass with correct error reasons +3. Configuration integration in `src/config.rs` +4. Documentation complete in users-guide and developers-guide +5.

No external crates without escalation. ## Artifacts and notes ### Key design decisions -1. **Canonicalization always requires resolution**: A path is rejected if it contains any symlinks after canonicalization. This is stricter than filesystem tools but more secure (prevents TOCTOU). - -2. **Allowlist is configuration-based**: Operators must explicitly configure allowed roots; Podbot never infers them. This enforces explicit security boundaries. - -3. **Permission validation is strict**: A directory must be writable by the container to be mounted. Attempts to mount read-only directories fail with a clear error. - -4. **Error messages are actionable**: Each error variant includes enough information for an operator to understand why a mount failed and how to fix it. +1.
