# Development
This is the first-read landing page for people and LLM coding agents working on
Narratio. It provides a concise repository orientation and routes each kind of
change to its canonical documentation.
Narratio is a stage-driven Go orchestrator for turning D&D session audio into
polished transcripts and generated artifacts. Start with the
[README](../README.md) for product context,
[Architecture](policy/architecture.md) for normative system boundaries, and the
[Internal Overview](internal/overview.md) for implemented component ownership.
Agents must read [Agent Policy](policy/agents.md) before recommending, planning,
or implementing changes. It owns implementation discipline and the default
commit-after-completed-work rule; it does not authorize pushing or releasing.
## Go Prerequisite
Maintained development and verification require Go 1.26. Use the official Go
1.26 toolchain before running repository commands.
## Policy Reading Guide
| Policy | Read before… |
| --- | --- |
| [Policy set provenance](policy/meta.md) | Adopting policies, checking upstream revisions, or updating the adopted policy set. |
| [Agents](policy/agents.md) | Recommending, planning, or implementing repository changes. |
| [Architecture](policy/architecture.md) | Planning or changing application code or its structure. |
| [Testing](policy/testing.md) | Selecting validation for code changes, or adding, changing, removing, or evaluating tests. |
| [Documentation](policy/documentation.md) | Writing, revising, or reorganizing documentation. |
| [OSS](policy/oss.md) | Adding or updating dependencies or incorporated third-party material, or changing licensing or attribution. |
| [Release](policy/release.md) | Preparing or publishing a release, changing release procedures, or making versioning and compatibility decisions. |
- Read applicable policies before making decisions they govern; multiple policies
may apply.
- Select policies using the task triggers above. Follow cross-references to
relevant sections when needed to resolve a concrete question.
- Reuse policies already available in context; reread when changed or no longer
available.
- Expand reading when the task's scope expands.
- When revising a policy itself, read that policy and any provisions elsewhere
affected by the revision.
## What To Read
| When working on | Read | Why |
| --- | --- | --- |
| Finding the package or component that owns current behavior | [Internal Overview](internal/overview.md) | It is the implemented component inventory and routes to focused internal documents. |
| Application shape, boundaries, dependency direction, runtime invariants, safety properties, or dependencies | [Architecture](policy/architecture.md) | It defines the intended system shape, ownership, and non-goals. |
| Any documentation addition or revision | [Documentation Policy](policy/documentation.md) | It defines canonical owners, audiences, current-behavior rules, and maintenance requirements. |
| Adding, changing, reviewing, rewriting, or deleting tests | [Testing Policy](policy/testing.md) | It defines risk-based sufficiency, durable test boundaries, test-double guidance, and test lifecycle decisions. |
| CLI composition or command behavior | [Internal Overview](internal/overview.md) and [CLI Reference](cli.md) | The overview routes to command ownership; the reference owns public syntax and invocation behavior. |
| Configuration loading, resolution, or user-visible configuration | [Internal Overview](internal/overview.md) and [Configuration](config.md) | The overview routes to implementation ownership; the reference owns fields, defaults, discovery, and validation. |
| Session workflow, status, restore, cleanup, or object storage | [Restore Internals](internal/command-restore.md), [Workspace Internals](internal/workspace.md), [Storage Internals](internal/storage.md), [Operations](operations.md), and [Troubleshooting](troubleshooting.md) | These separate implementation mechanics, operator procedures, and symptom-driven recovery. |
| Pipeline sequencing or the behavior of a stage | [Internal Overview](internal/overview.md) and its focused stage documents | The overview owns the implemented stage inventory and routes to each stage contract. |
| Adapters or external tool contracts | [Adapter Internals](internal/adapters.md) and [Integration Contracts](integrations/README.md) | The internal guide owns adapter composition and mechanics; integration documents own external formats and protocols. |
| Manifests, artifacts, workspace paths, or publish behavior | [Manifest Internals](internal/manifest.md), [Artifact Internals](internal/artifacts.md), [Workspace Internals](internal/workspace.md), [Publish Internals](internal/stage-publish.md), and [Operations](operations.md) | These separate implementation state and resolution from operator-visible layout and lifecycle. |
| Maintained configuration or input examples | [Configuration](config.md) and [Examples](../examples/README.md) | The reference owns field meanings; the examples directory owns complete copyable files. |
| Preparing, validating, or publishing a release | [Release Policy](policy/release.md) and [Release Procedure](release.md) | Policy owns requirements and exceptions; the procedure owns concrete validation, guarded publication, and optional later inspection. |
| Proposed or unimplemented behavior | `docs/roadmap/` | Future work belongs only in roadmap documentation until implemented. |
For an existing subsystem, also inspect its focused tests and package-level
contracts before changing behavior.
## Validation
Use focused package tests while iterating. Every pull request and push runs the
following repository-wide checks before it can be accepted:
```sh
go test ./...
go test -race ./...
go vet ./...
go build ./...
go test ./internal/doccheck
go test ./internal/config -run '^TestExamplesLoadAndValidate$'
```
The documentation check verifies local Markdown links and the dependency graph
of the Woodpecker workflows. The configuration check loads every maintained
pipeline and session example. Tag CI independently revalidates the tagged source
before asynchronous asset delivery; it is not a second synchronous release
prerequisite. The normal maintainer entry point is the single publication command
in the [Release Procedure](release.md).
Woodpecker also runs `go test -race -shuffle=on -count=3 ./...` on its scheduled
job to expose ordering and repeatability defects. Current runners cross-compile
the supported Linux amd64 and arm64 targets and the best-effort macOS arm64
target. The macOS cross-build establishes compilation only, not native runtime
evidence. Add a native check only when an official runner label and successful
native-run evidence are available.
