FuzzNewManifestFromReader fails when the parser returns both or neither
of a manifest and an error, or allocates more than sixteen times its
input and the decompressed data it may read, plus room for the decoder's
window. make test runs the committed seed corpus; make fuzz fuzzes for
one minute, by hand only.
Parser bug: MaxDecompressedSize did not bound decompression. The zstd
decoder decoded a payload under 128 KiB in full, each frame up to its
own 64 GiB limit, before the LimitReader read any of it. It now decodes
synchronously, only what the LimitReader reads, with MaxDecompressedSize
as its limit. Regression seeds: a frame claiming 8 GiB, and two frames
each under the limit and together over it.
Model: opus-5-5
Adds .prettierrc and .prettierignore, a single script/prettier entrypoint shared by fmt and fmt-check so the two cannot drift, and prettier 3.9.6 pinned by yarn.lock integrity hash.
Markdown formatting is now gated in the authoritative Docker build via a new mdfmt stage, since the golangci-lint image has no node. REPO_POLICIES.md is ignored so local tooling cannot drift it from upstream.
Removes the || true that made the previous prettier invocation unable to fail.
Adopts golangci-lint v2.12.2 and the canonical .golangci.yml (default: all), and fixes all resulting findings across the tree.
Two intended behavior changes: absent MFFilePath.Mtime is handled explicitly in freshen, list and export rather than dereferenced (main panicked); gpg positional key IDs now follow an explicit -- end-of-options marker.
All twelve reworded user-visible error messages restored to byte-identical parity with main and pinned by tests.
Closes#39
Splits the Dockerfile into a dedicated lint stage using the `golangci/golangci-lint` image directly, rather than copying the binary into the builder stage.
## Changes
### Dockerfile
- **Lint stage** (`AS lint`): Uses the pre-built `golangci/golangci-lint` image (pinned by sha256) to run `make fmt-check` and `make lint`. This is a self-contained stage with its own `go mod download` and source copy.
- **Builder stage** (`AS builder`): Runs only `make test` and the final binary build. No longer needs golangci-lint installed.
- **Stage dependency**: `COPY --from=lint /src/go.sum /dev/null` forces BuildKit to always execute the lint stage (without this, unused stages are silently skipped).
- Both stages touch `mfer/mf.pb.go` to prevent make from trying to regenerate via protoc.
With BuildKit, the lint and builder stages run in parallel after their shared `go mod download` layers complete, so lint/formatting failures surface much faster without blocking on test execution.
### Makefile
- Added `lint` to the `check` target prereqs: `check: test lint fmt-check` (was `check: test fmt-check`), matching the [REPO_POLICIES](https://git.eeqj.de/sneak/prompts/raw/branch/main/prompts/REPO_POLICIES.md) requirement.

- Add --sign-key flag and MFER_SIGN_KEY env var to gen and freshen commands
- Sign inner message multihash with GPG detached signature
- Include signer fingerprint and public key in outer wrapper
- Add comprehensive tests with temporary GPG keyring
- Increase test timeout to 10s for GPG key generation
Changed the default behavior to exclude dotfiles (files/dirs starting with .)
which is the more common use case. Added --include-dotfiles flag for when
hidden files need to be included in the manifest.
