# Implementation decisions: Initial project setup and DNS operation catalog

## Context

- **Change folder:** `docs/changes/00001-setup-project/`
- **Branch:** `feature/C-00001-setup-project`
- **Scope:** Documentation and scaffolding only (no Go source)

## Decisions

| # | Area | Decision | Rationale |
|---|------|----------|-----------|
| 1 | Git baseline | Baseline commit pushed before implementation edits | Per `implement-change` skill and plan step 0 |
| 2 | BIND guide | Single `docs/bind-tsig-configuration.md` with all spec section 9 topics | Primary deliverable of this change |
| 3 | Example secret | Placeholder Base64 in guide (not a real key) | Illustration only; guide warns against committing secrets |
| 4 | `.gitignore` | Added `.env` and `.env.*` | Spec requirement 10; was missing from specify phase |
| 5 | Library code | No `doc.go` or placeholder `godns` package | Plan explicitly excludes `*.go`; first API change adds packages |

## Deviations from plan

- None.

## Follow-ups / risks

- **`go work sync` at workspace root** may fail if sibling module `log-analyzer` lacks `go.mod` (pre-existing workspace issue). AC-1 verification should use `go-dns/go.mod` directly or fix workspace separately.
- **Gitea repo** was available; baseline and feature branch push succeeded.
- **verify-agent:** Run full AC-1 through AC-10 checklist from `plan.md`.
- **Next change:** Implement `package godns` wire protocol (RFC 2136 UPDATE, AXFR, TSIG) per backlog/spec.
