clawbot 76116005c8 Reject manifests whose file entries decode far larger than their bytes (closes #123)
check / check (push) Waiting to run
Before decoding the manifest, the parser adds up what decoding sets
aside for each file entry, hash, timestamp and MIME type, however short
its encoding, and refuses the manifest once that passes 8 times the
decompressed size; manifests mfer writes come to at most about 7.15
times. Empty entries decoded to about 50 times their size: under 1 KB of
manifest allocated about 500 MB. Fields the decoder does not know are
dropped; kept, they took up to 5 times more. A test refuses entries
counted just over 8 times and loads them just under. The fuzz ceiling
rises from 16 to 20 times the input and decompressed data; seeds of
empty entries and of empty hashes fail it without the fix.

clawbot d00982b329 Fuzz NewManifestFromReader and cap the zstd decoder (closes #65)
check / check (push) Successful in 1m5s
FuzzNewManifestFromReader fails when the parser returns both or neither
of a manifest and an error, or allocates more than a fixed multiple of
its input and the decompressed data it may read, plus room for the
decoder's window buffers. make test runs the seed corpus; make fuzz
fuzzes for one minute.

Parser bug: MaxDecompressedSize did not bound decompression; the zstd
decoder decoded a payload under 128 KiB in full before the LimitReader
read any of it. It now decodes only what the LimitReader reads and
refuses windows over the 8 MiB mfer writes with. Seeds: a frame claiming
8 GiB, two frames together over the limit, empty frames with growing
windows.

clawbot 5683d0f4ff Configure prettier and make fmt-check cover markdown (closes #69)
check / check (push) Successful in 4s
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.

clawbotandclawbot 6ba32f5b35 Add REPO_POLICIES.md, rename CLAUDE.md to AGENTS.md, deduplicate (#51)
Closes #48

## Changes

- **Added `REPO_POLICIES.md`** — copied from the standard template at [sneak/prompts](https://git.eeqj.de/sneak/prompts/src/branch/main/prompts/REPO_POLICIES.md) (last_modified: 2026-03-10). This is the authoritative cross-project policy document covering repository structure, tooling, Docker, formatting, testing, and workflow standards.

- **Renamed `CLAUDE.md` → `AGENTS.md`** — deduplicated content:
  - Rules already covered by `REPO_POLICIES.md` (e.g. `git add -A`, Makefile targets) are no longer repeated
  - `AGENTS.md` retains only agent-specific workflow instructions: test-first bug fixing, no AI attribution in commits, per-change make fmt/test/lint workflow, and repo-specific notes (proto files, FORMAT.md, TODO.md)

- **Updated `README.md`** — added a reference to `REPO_POLICIES.md` in the Participation section

- **Formatting** — `make fmt` (prettier) applied to all markdown files

## Verification

`docker build .` passes clean — lint, fmt-check, and all tests green.
