sneak d90bef8580 Add the required README sections (closes #75)
check / check (push) Failing after 1s
Policy names five README sections that were missing or misnamed.

The Description first line now names the project, purpose, category,
WTFPL license, and author. A new Getting Started section gives a
copy-pasteable build-from-source block and gen/check/fetch usage; every
command was run against a built binary. Problem Statement and Proposed
Solution are consolidated under a new Rationale heading, keeping the
prose rather than duplicating it. A new Design section documents the
package layout: mfer/ library, internal/cli commands, internal/log and
internal/bork support, cmd/mfer entrypoint, and the committed protobuf
code. Authors is renamed Author with the canonical link.

Getting Started uses go build because the make build target invokes
protoc, which script/bootstrap does not install.

# Getting Started
`mfer` builds from source with a Go 1.23+ toolchain. The generated protobuf code
is committed, so no `protoc` toolchain is required:
```sh
git clone https://git.eeqj.de/sneak/mfer.git
cd mfer
go build -o bin/mfer ./cmd/mfer
```
Generate a manifest for a directory tree, verify it later, and fetch a published
tree by URL:
```sh
# Write .index.mf describing every file under the current directory.
bin/mfer gen .
# Verify the files on disk against the manifest. Exits nonzero if any file
# is missing or corrupted.
bin/mfer check .index.mf
# Download and cryptographically verify a tree published over HTTP: mfer
# fetches <url>/index.mf, then downloads every file it lists.
bin/mfer fetch https://example.com/tree/
```
Run `bin/mfer help` for the full command list, or `bin/mfer <command> --help`
for a single command's options.

# Design
The repository is split into a reusable library and a thin command-line wrapper
around it.
- `mfer/` is the reusable library and the heart of the project: it defines the
manifest format and implements building, scanning, checking, serialization,
and signing. The protobuf schema is `mfer/mf.proto`, and the generated code it
produces (`mfer/mf.pb.go`) is committed alongside it so the library builds
with `go get` and needs no `protoc` toolchain.
- `internal/cli/` holds the command implementations — `gen`, `check`, `freshen`,
`export`, `list`, and `fetch` — that wire the library to the command-line
interface.
- `internal/log/` provides the logging used across the commands.
- `internal/bork/` provides error-handling support.
- `cmd/mfer/` is the entrypoint: its `main` package assembles the pieces above
into the `mfer` binary.
Everything under `internal/` is private to this repository; only the `mfer/`
package is intended for import by other software.

# TODO # TODO: Remaining Work for 1.0
Open work, open design questions included, is tracked in this repo's issues: ## Design Questions (Owner Decision Required)
[https://git.eeqj.de/sneak/mfer/issues](https://git.eeqj.de/sneak/mfer/issues).
These require @sneak's input before implementation. Answers should be added
inline below each question.
### Format Design
**1. Should `MFFileChecksum` be simplified?** Currently it's a separate message
wrapping a single `bytes multiHash` field. Since multihash already
self-describes the algorithm, `repeated bytes hashes` directly on `MFFilePath`
would be simpler and reduce per-file protobuf overhead. Is the extra message
layer intentional (e.g. planning to add per-hash metadata like `verified_at`)?
> _answer:_
**2. Should file permissions/mode be stored?** The format stores mtime/ctime but
not Unix file permissions. For archival use this may not matter, but for
software distribution or filesystem restoration it's a gap. Should we reserve a
field now (e.g. `optional uint32 mode = 305`) even if we don't populate it yet?
> _answer:_
**3. Should `atime` be removed from the schema?** Access time is volatile,
non-deterministic, and often disabled (`noatime`). Including it means two
manifests of the same directory at different times will differ, which conflicts
with the determinism goal. Remove it, or document it as "never set by default"?
> _answer:_
**4. What are the path normalization rules?** The proto has `string path` with
no specification about: always forward-slash? Must be relative? No `..`
components allowed? UTF-8 NFC vs NFD normalization (macOS vs Linux)? Max path
length? This is a security issue (path traversal) and a cross-platform
compatibility issue. What rules should the spec mandate?
> _answer:_
**5. Should we add a version byte after the magic?** Currently `ZNAVSRFG` is
followed immediately by protobuf. Adding a version byte (`ZNAVSRFG\x01`) would
allow future framing changes without requiring protobuf parsing to detect the
version. `MFFileOuter.Version` serves this purpose but requires successful
deserialization to read. Worth the extra byte?
> _answer:_
**6. Should we add a length-prefix after the magic?** Protobuf is not
self-delimiting. If we ever want to concatenate manifests or append data after
the protobuf, the current framing is insufficient. Add a varint or fixed-width
length-prefix?
> _answer:_
### Signature Design
**7. What does the outer SHA-256 hash cover — compressed or uncompressed data?**
The code currently hashes compressed data (good for verifying before
decompression), but this should be explicitly documented. Which is the intended
behavior?
> _answer:_
**8. Should `signatureString()` sign raw bytes instead of a hex-encoded
string?** Currently the canonical string is `MAGIC-UUID-MULTIHASH` with hex
encoding, which adds a transformation layer. Signing the raw `sha256` bytes (or
compressed `innerMessage` directly) would be simpler. Keep the string format or
switch to raw bytes?
> _answer:_
**9. Should we support detached signature files (`.mf.sig`)?** Embedded
signatures are better for single-file distribution. Detached `.mf.sig` files
follow the familiar `SHASUMS`/`SHASUMS.asc` pattern and are simpler for HTTP
serving. Support both modes?
> _answer:_
**10. GPG vs pure-Go crypto for signatures?** Shelling out to `gpg` is fragile
(may not be installed, version-dependent output).
`github.com/ProtonMail/go-crypto` provides pure-Go OpenPGP, or we could use
Ed25519/signify (simpler, no key management). Which direction?
> _answer:_
### Implementation Design
**11. Should manifests be deterministic by default?** This means: sort file
entries by path, omit `createdAt` timestamp (or make it opt-in), no `atime`.
Should determinism be the default, with a `--include-timestamps` flag to opt in?
> _answer:_
**12. Should we consolidate or keep both scanner/checker implementations?**
There are two parallel implementations: `mfer/scanner.go` + `mfer/checker.go`
(typed with `FileSize`, `RelFilePath`) and `internal/scanner/` +
`internal/checker/` (raw `int64`, `string`). The `mfer/` versions are superior.
Delete the `internal/` versions?
> _answer:_
**13. Should the `manifest` type be exported?** Currently unexported with
exported constructors (`NewManifestFromReader`, `NewManifestFromFile`).
Consumers can't declare `var m *mfer.manifest`. Export the type, or define an
interface?
> _answer:_
**14. What should the Go module path be for 1.0?** Currently
`sneak.berlin/go/mfer` in `go.mod` but `git.eeqj.de/sneak/mfer/mfer` in the
proto `go_package` option. Which is canonical?
> _answer:_
## Implementation Tasks
### Repo Infrastructure
- [ ] Add `.golangci.yml` (fetch from
`https://git.eeqj.de/sneak/prompts/raw/branch/main/.golangci.yml`)
- [ ] Add `.editorconfig`
- [ ] Add `.gitea/workflows/check.yml` that runs `docker build .`
### Format & Correctness
- [ ] Resolve proto `go_package` path inconsistency
(`git.eeqj.de/sneak/mfer/mfer` vs `sneak.berlin/go/mfer`)
- [ ] Specify path invariants — add proto comments requiring UTF-8,
forward-slash, relative paths, no `..`, no leading `/`; validate in
`Builder.AddFile` and `Builder.AddFileWithHash` (pending design question
answer)
- [ ] Remove or deprecate `atime` from proto (pending design question answer)
- [ ] Reserve `optional uint32 mode = 305` in `MFFilePath` for future file
permissions (pending design question answer)
- [ ] Add version byte after magic — `ZNAVSRFG\x01` for format version 1
(pending design question answer)
- [ ] Write format specification document — separate from README: magic, outer
structure, compression, inner structure, path invariants, signature
scheme, canonical serialization
### Library
- [ ] Delete `internal/scanner/` and `internal/checker/` — consolidate on
`mfer/` package versions; update CLI code (pending design question answer)
- [ ] Add deterministic file ordering — sort entries by path (lexicographic,
byte-order) in `Builder.Build()`; add test asserting byte-identical output
from two runs
- [ ] Add decompression size limit — `io.LimitReader` in `deserializeInner()`
with `m.pbOuter.Size` as bound
- [ ] Fix `errors.Is` dead code in checker — replace with `os.IsNotExist(err)`
or `errors.Is(err, fs.ErrNotExist)`
- [ ] Fix `AddFile` to verify size — check `totalRead == size` after reading,
return error on mismatch
- [ ] Export the `manifest` type or define a public interface (pending design
question answer) — currently consumers cannot hold a reference to a loaded
manifest in their own type declarations
- [ ] Replace GPG subprocess calls with pure-Go crypto (pending design question
answer) — current implementation shells out to `gpg` which may not be
installed
- [ ] Add timeout to any remaining subprocess calls
### CLI
- [ ] Fix flag naming — all CLI flags should use kebab-case as primary
(`--include-dotfiles`, `--follow-symlinks`)
- [ ] Fix URL construction in fetch — use `BaseURL.JoinPath()` or
`url.JoinPath()` instead of string concatenation
- [ ] Add progress rate-limiting to Checker — throttle to once per second,
matching Scanner
- [ ] Add `--deterministic` flag or make it default — omit `createdAt`, sort
files (pending design question answer)
- [ ] Wire `--version` flag properly (currently only a `version` subcommand
exists; top-level `--version` shows urfave/cli generic output)
- [ ] Add retry logic to `fetch` — currently no retries on transient HTTP
errors; needs exponential backoff
- [ ] `fetch` command uses bare `http.Get` with no timeout — needs `http.Client`
with configurable timeout
### Testing & Robustness
- [ ] Add fuzzing tests for `NewManifestFromReader` — protobuf deserialization
of untrusted input needs fuzz coverage
- [ ] Add integration test for `freshen` CLI command — current tests only verify
setup, not the actual freshen operation end-to-end
- [ ] Add test for `fetch` CLI command end-to-end (currently only `downloadFile`
is tested)
### Documentation
- [ ] Promote `FORMAT.md` as primary spec reference; README should link to it
more prominently
- [ ] Audit and update all error messages for consistency and helpfulness
- [ ] Document the signature scheme more thoroughly (canonical string format,
verification steps)
### Release
- [ ] Finalize Go module path
- [ ] Update version constant in `mfer/constants.go`
- [ ] Add `--version` output matching SemVer
- [ ] Tag `v1.0.0`

# Status
pre-1.0. No git tags. README section "TODO: Remaining Work for 1.0" lists open
design questions and implementation tasks; policy compliance work is in flight
and unmerged.
# Next Step
Work through the remaining compliance items folded from the 2026-07-02 audit
(the first group under Future Steps): `.editorconfig`, `.gitignore` coverage,
gofumpt-based `fmt-check`, README "Getting Started", and the rest.
`.golangci.yml` and `TODO.md` are tracked and committed as of 2026-08-07, so the
only thing left of the `chore/align-repo-policies` branch is the list below.
# Completed Steps
- 2026-09-21: added the required README sections — named author, license, and
category in the Description first line; added Getting Started (verified
install/usage block), Rationale (folding in Problem Statement and Proposed
Solution), and a Design section for the package layout; renamed Authors to
Author (#75)
- 2026-09-21: added the canonical `.editorconfig`, made `.gitignore` cover
secrets, OS, editor, and Go artifacts, and removed the dead Drone CI
references from `.gitignore` and `bin/gitrev.sh` (#72)
- 2026-08-09: added `.prettierrc`/`.prettierignore`, gave `script/fmt` and
`script/fmt-check` one shared prettier file set via `script/prettier`, dropped
the `|| true` that hid prettier failures, and added a node-based Dockerfile
stage so a markdown formatting violation fails `docker build .` (#69)
- 2026-08-07: updated golangci-lint to v2.12.2 everywhere it is pinned
(`Makefile`, `Dockerfile`), added the canonical `.golangci.yml`
(`default: all`), and fixed all resulting lint findings across the codebase
- 2026-07-07 Adopted scripts-to-rule-them-all: `script/` entrypoints, Makefile
shims, README Entrypoints section
- 2026-07-03: aligned repo tooling, docs, and config with standardized policies
(7d9a138, on chore/align-repo-policies, unmerged)
- 2026-06-28: moved to standardized repo policies (#56, on main)
- 2026-04-07: added 1.0 roadmap as README TODO section, removed old TODO.md
(#54)
- 2026-03-20: added Gitea Actions CI workflow (#53)
- 2026-03-17: added REPO_POLICIES.md, renamed CLAUDE.md to AGENTS.md (#51);
removed committed .index.mf (#52)
- 2026-03-15: split Dockerfile with pre-built golangci-lint stage for faster CI
(#45)
- 2026-03-01: 1.0 quality polish: code review, tests, bug fixes, docs (#32)
- 2026-02-20: deterministic file ordering in Builder.Build() (#28); removed
committed vendor/modcache archives (#35)
- 2026-02-08: added --seed flag for deterministic manifest UUID
# Future Steps
- Compliance (fold of TODO.md audit 2026-07-02; verify which items the in-flight
branch already closes, then check off):
- Add .editorconfig (canonical copy from sneak/prompts)
- Make .gitignore cover secrets (.env, _.key, _.pem), OS files (.DS_Store),
and editor files (_.swp, _~)
- Make fmt-check/lint verify with gofumpt, not gofmt -l, so `make check`
matches what `make fmt` writes
- Add README "Getting Started" section with copy-pasteable install/usage
block
- Move FORMAT.md from repo root to docs/ and update the AGENTS.md reference
- Pin Makefile-installed Go tools (`protoc-gen-go@v1.28.1`,
`golangci-lint@v2.12.2`) by module hash, not mutable tag
- Set `make test` timeout to 30s (currently 10s)
- Add explicit README "Rationale" heading (content exists under other
names); name the author in the README Description first line
- Reconcile root-level AGENTS.md with directory-hygiene policy (keep or
relocate)
- Add a `make build` target
- Rewrite `make hooks` to use printf or a heredoc instead of non-portable
`echo '...\n...'`
- Answer the 14 owner design questions in the README 1.0 roadmap:
- Format: simplify MFFileChecksum; store file mode; drop atime; specify path
normalization rules; version byte after magic; length-prefix after magic
- Signatures: hash covers compressed or uncompressed data; sign raw bytes vs
hex canonical string; detached .mf.sig support; GPG subprocess vs pure-Go
crypto
- Implementation: deterministic manifests by default; consolidate duplicate
scanner/checker implementations; export the manifest type; canonical Go
module path for 1.0
- Format and correctness:
- Resolve proto go_package vs go.mod module path inconsistency
- Specify and validate path invariants (UTF-8, forward-slash, relative, no
.., no leading /)
- Remove or deprecate atime; reserve mode field; add version byte (all
pending design answers)
- Write a standalone format specification document
- Library:
- Delete internal/scanner and internal/checker; consolidate on the mfer/
package versions (pending design answer)
- Add decompression size limit via io.LimitReader in deserializeInner()
- Fix errors.Is dead code in checker; make AddFile verify totalRead == size
- Export manifest type or define a public interface (pending)
- Replace GPG subprocess with pure-Go crypto (pending); add timeouts to
remaining subprocess calls
- CLI:
- Kebab-case primary flag names; fix fetch URL construction with
url.JoinPath; add http.Client timeout and retry with backoff to fetch;
rate-limit Checker progress output; add --deterministic flag or default;
wire top-level --version properly
- Testing:
- Fuzz NewManifestFromReader; end-to-end tests for freshen and fetch
- Documentation:
- Promote docs/FORMAT.md as primary spec reference; audit error messages;
document the signature scheme fully
- Release:
- Finalize module path, bump version constant, SemVer --version output, tag
