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.

Mitigation: -provide clear defaults (System < User < Project) and write comprehensive guides. - -### Potential for Scope Confusion - -Nested scopes (e.g., User contains Workspace) require careful definition. -Mitigation: define scopes as an open enum; applications can extend with custom -types if needed. - -### Early Merge Synchronization - -The guarantee that early `merged_file_value()` matches final merge must hold -even with `extends` chains. Mitigation: comprehensive integration tests. - ---- - -## Unresolved Questions - -### 1. Custom Scopes - -Should applications be able to define their own scopes (e.g., Workspace, -Cluster)? - -- **Current proposal**: Open enum; applications define variants as needed -- **Alternative**: Closed set of scopes; custom needs must map to existing ones - -### 2. Scope Aliases - -Should netsuke's `.netsuke.toml` in user directory be called "User" or -"Project"? - -- **Current proposal**: Application names their scopes; "User" and "Project" are - suggestions -- **Alternative**: Standardize names across ecosystem - -### 3. Extends Precedence Across Scopes - -If User config extends Base, and Project config extends User, what merge order -applies? - -- **Current proposal**: All extends chains load as separate layers; final order - is User-scope < Project-scope -- **Alternative**: Extends chains respect cross-scope order; Project-scope - extends can reference User values - -### 4. Performance Profiling - -How much overhead does multi-scope discovery add versus first-match? Should -there be an early-exit optimization if Project scope finds a match? - -### 5. Error Recovery - -If a Project-scope file is malformed, should discovery fall back to User-only -config? - -- **Current proposal**: No; malformed present files always error -- **Alternative**: Optional fallback mode for graceful degradation - ---- - -## Next Steps - -1. **Design review**: Gather feedback from netsuke team and community -2. **Prototype**: Implement stages 1–2 as a proof-of-concept -3. **netsuke trial**: Apply to netsuke; verify fail-closed and early-diag - semantics -4. **Testing**: Comprehensive test matrix for all scenarios -5. **Macro design**: Refine `discovery(...)` attribute syntax -6. **Release**: Ship with documentation and migration guide - ---- - -## References - -- [Netsuke config discovery](file:///tmp/lody-title-agent/src/cli/discovery.rs) -- [ortho-config ConfigDiscovery]( - file:///tmp/lody-title-agent) — baseline API -- [RFC 0001: Environment Variable Aliases](rfc-ortho-config-env-aliases.md) — - Related feature for alias chains -- [Kubernetes ConfigMap - composition](https://kubernetes.io/docs/concepts/configuration/configmap/) — - Multi-scope precedence example -- [Docker Compose environment file - precedence](https://docs.docker.com/compose/env-file/) — Real-world stacking - example -- [systemd EnvironmentFiles](https://www.freedesktop.org/software/systemd/man/systemd.exec.html#EnvironmentFiles=) - — Ordered file merging pattern
