+# Workflow
+
+- branch (from `main`)
+- do the work in Next Step
+- move Next Step to the top of Completed Steps
+- move the top item of Future Steps into Next Step
+- commit (`TODO.md` changes in the same commit as the work)
+- merge to `main` if the branch is not protected, otherwise open a PR
+- push
+
+# Status
+
+- pre-1.0
+
+# Next Step
+
+- bring the repo into full policy compliance (work the Repo Policy
+  Compliance checklist below)
+
+# Completed Steps
+
+- `git init` with README-only first commit; code baseline committed on
+  `main` (2026-07-22)
+- implement `scan`, `report`, and `trees` subcommands (pre-git history)
+
+# Future Steps
+
+- add a remote on git.eeqj.de and push (`main` plus tags)
+- convert Makefile targets to scripts-to-rule-them-all `script/`
+  entrypoints like the other managed repos
+- tag `v0.0.1` once the compliance branch is merged
+- possible later features (explicitly out of scope per README):
+  full-content verification of candidates, removal-script helpers

+# Repo Policy Compliance
+
+Audited 2026-07-22 against `REPO_POLICIES.md` (2026-07-06), the existing
+repo checklist, and the Go styleguide. Code is already gofmt-clean, so no
+standalone formatting commit is needed.
+
+- [ ] `.gitignore` missing — the compiled `sfdupes` binary and
+      `files.dat` sit untracked in the tree; needs OS/editor/Go
+      artifacts plus secrets patterns
+- [ ] `.editorconfig` missing
+- [ ] `LICENSE` missing and README has no License section (MIT assumed
+      from house convention — user to confirm)
+- [ ] `REPO_POLICIES.md` missing from repo root
+- [ ] `.golangci.yml` missing (install canonical copy); code must then
+      pass `make lint`
+- [ ] `Makefile` lacks required targets `test`, `lint`, `fmt`,
+      `fmt-check`, `docker`, `hooks`; `check` currently depends on
+      `build`, which writes the binary (`make check` must not modify
+      files)
+- [ ] no tests — `go test ./...` has nothing to run; policy requires
+      real tests with a 30-second timeout and the conditional `-v`
+      rerun pattern
+- [ ] `Dockerfile` missing — Go multistage with hash-pinned images:
+      fail-fast lint stage, build stage running `make check`
+- [ ] `.dockerignore` missing
+- [ ] `.gitea/workflows/check.yml` missing (`docker build .` on push,
+      checkout action pinned by commit SHA)
+- [ ] README lacks required sections: Description first line
+      (name/purpose/category/license/author), Getting Started,
+      Rationale, TODO, License, Author
+- [ ] README non-goal "no git repository setup and no CI" is stale now
+      that the repo is under git with CI
+- [ ] pre-commit hook not installed (`make hooks` once the target
+      exists)
+
+Accepted divergences (no action):
+
+- flat single-package layout with `.go` files in the repo root — fine
+  for a small single-binary tool per the Go styleguide; the tracker
+  audit agrees
+- `go test` runs without `-race` — the repo mandates `CGO_ENABLED=0`
+  (pure-Go builds) and the race detector requires cgo
