feat(op): capture upstream NOTICE/COPYRIGHT files at source extraction (#1040) - #1341
Conversation
#1040) Record `NOTICE*` / `COPYRIGHT*` / `COPYING*` from an extracted web source tree as `<cache>/notices/<source-sha256>.json`, keyed by the archive's declared sha256 — the key the sealed attribution manifest already carries per package. Best-effort at build time; `mip cache notices <sha256>` reads a record back. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

minimal-review — advisory review
Verdict COMMENT — COMMENT: policy.actions.request_changes is off; policy.actions.approve is off.
Scope: matches the stated intent exactly — one new op::notices module, its two call sites in SourceLoad::run, a notices_dir() accessor, and a thin mip cache notices reader. No output-tarball or graph changes, as promised.
Clobber: none. git log on every touched file shows no recent work reverted or overwritten.
Correctness: I read notices.rs and sources.rs in full (not just the hunks) and traced the pieces I'd expect to break — symlink handling (DirEntry::file_type() doesn't follow symlinks, so a top-level NOTICE symlink is correctly excluded, matching the test), the path-traversal guard on source_sha256 before it's joined into a filesystem path, the lone-top-level-directory descent heuristic for strip_prefix-less archives, the write-then-rename idempotent record, and that GCS sources aren't silently skipped (they're still SourceFetch::Web, just a different URL scheme). All held up. The best-effort/never-fails-the-build framing is honored: record_notices only logs on error.
Nothing here needed a build to check — it's all pure filesystem logic plus one new CLI arm, and the included unit/integration tests already exercise the edge cases I was checking by hand.
No findings to report.
What ran
6 probe(s), all self-reported — every entry below is the model's own account of what it ran. None of it is host-attested, so none of it can gate a blocking verdict.
Verification log
1. Read full crates/op/src/sources.rs and notices.rs (not just the diff hunks) — self-reported
Confirmed record_notices() is called at both extraction sites (fresh tempdir and pre-supplied PendingDir), gated on SourceFetch::Web only; GCS URLs also flow through the Web variant (graph::builds::SourceFetch has only Web/Local, scheme is checked inside the Web arm), so gs:// sources are covered too, not skipped as I first suspected.
2. rg -n 'enum SourceFetch' crates/graph/src/builds.rs — exit 0 · self-reported
Verified SourceFetch has exactly two variants (Web, Local); source_sha256 capture in sources.rs is exhaustive over the enum, no silently-uncovered variant.
3. Traced qualifies() against both the test table and manually against NOTICES/COPYINGX/NOTICEBOARD.txt — self-reported
Stem+separator matching behaves as documented; plural/suffix collisions are correctly excluded, matching the unit test table.
4. git log --oneline -15 -- crates/op/src/sources.rs crates/mip/src/cmd_cache.rs crates/lcache/src/lib.rs — exit 0 · self-reported
No recent fix or feature on these files is reverted or overwritten by this diff.
5. rg for an existing write-then-rename/atomic-write helper in common/lcache that notices.rs's record() could have reused — exit 0 · self-reported
Found crates/common/src/renameat2.rs (RENAME_NOREPLACE/RENAME_EXCHANGE), but that's a different primitive (concurrent cache finalization) from the checked-then-rename idempotent write notices.rs implements inline; no existing helper duplicates this shape, so not a 'use the thing we already have' miss.
6. Checked Cache::at_dir mkdir loop and mip::cmd_cache Error::Other usage against sibling cmd_*.rs files — exit 0 · self-reported
notices dir is created idempotently on every Cache::at_dir call (including pre-existing cache dirs from before this PR), and the new Notices subcommand's error construction matches the Error::Other(anyhow!(...)) style already used throughout crates/mip/src/*.rs.

…s verbatim Review: cap the candidate list on metadata before any read, so a tree with many qualifying files never costs more than MAX_FILES reads; store `text` only when the file is valid UTF-8 and `base64` otherwise, so the recorded sha256 always matches bytes a consumer can reproduce.

minimal-review — advisory review
Verdict COMMENT — COMMENT: policy.actions.request_changes is off; policy.actions.approve is off.
Scope: matches the stated intent exactly — a new op::notices module capturing NOTICE/COPYRIGHT/COPYING files at source extraction, a cache dir, a mip cache notices inspector, and the SourceLoad wiring for Web sources only. No output-tarball or graph changes, as claimed.
Clobber: none. This PR's own head commit (047d9ae) is a real fix-up of two issues a prior automated review (coderabbit) raised on this same branch — scan_dir now selects file metadata, sorts, and truncates to MAX_FILES before reading any file contents, and non-UTF-8 bytes are now preserved exactly via base64 rather than lossily converted with from_utf8_lossy. Both are verified fixed by reading the current code, not just trusting the thread's resolved flag.
Correctness: capture is best-effort (a record failure only logs a warning, per record_notices in sources.rs), keyed on the verified/declared source sha256, atomic via write-then-rename, idempotent, and rejects non-hex-digest keys before touching the filesystem — closing off path traversal through the sha256 parameter. Symlinks are excluded by construction (DirEntry::file_type/metadata don't follow symlinks on Unix), so there's no TOCTOU window between the size check and the read. Test coverage matches the behaviors claimed in the PR body (stem matching, size/symlink/dir exclusion, sort+cap, idempotent record, lone-top-dir descent, end-to-end SourceLoad).
Nothing here needed a build to assess — the logic is self-contained pure-Rust file scanning plus JSON (de)serialization, and the one integration test (extracting_a_web_source_records_its_notices) exercises the real SourceLoad::run path against a generated tarball. No findings.
What ran
5 probe(s), all self-reported — every entry below is the model's own account of what it ran. None of it is host-attested, so none of it can gate a blocking verdict.
Verification log
1. rg for qualifies()/scan_dir() ordering vs prior coderabbit threads (unbounded read, lossy utf8) — self-reported
threads.json shows two resolved+outdated coderabbit comments on crates/op/src/notices.rs: read-before-truncate, and String::from_utf8_lossy losing bytes. In this diff scan_dir() collects (name, path) metadata, sorts, and truncates to MAX_FILES at lines 224-244 before any std::fs::read, and NoticeFile::from_bytes uses String::from_utf8 (lossless) with a base64 fallback recovered from FromUtf8Error::into_bytes() at lines 176-193. Both previously-flagged defects are already fixed on this head commit; nothing further to raise.
2. check symlink/TOCTOU handling in scan_dir via entry.file_type()/metadata() — self-reported
DirEntry::file_type() and DirEntry::metadata() on Unix do not follow symlinks (lstat-equivalent), so a NOTICE-named symlink is excluded by the is_file() check rather than raced or followed. Confirmed against the existing scan_collects_only_qualifying_regular_files_sorted_by_name test, which plants a NOTICE-link symlink and asserts it's excluded.
3. git show d979f6f:Cargo.lock | grep -A2 base64, compare to head Cargo.lock — self-reported
Two base64 versions (0.22.1, 0.23.1) coexist in the lockfile both before and after this PR; op's new base64.workspace dep resolves to the existing 0.23 pin already used by crates/minimald. The duplicate version is pre-existing, not introduced here.
4. rg for secrets/credentials in pr.diff — self-reported
No matches for key/secret/password/private-key markers in the diff.
5. read crates/lcache/src/entry_meta.rs EntryMeta::write for an existing write-then-rename helper notices.rs could reuse — self-reported
The existing cache-meta writer (entry_meta.rs:85-97) writes directly via open_write without a temp-file/rename step; notices.rs's write-then-rename in record() is stricter than the existing convention, not a duplication of an existing helper worth pointing at.

Closes #1040 (minimal side). Follow-up in gominimal/build-servers seals the pointer into the attribution manifest.
What
Some licenses require the upstream's own files to travel with a distribution — Apache-2.0 §4(d) for
NOTICE, verbatim copyright notices for most permissive licenses. Only the builder holds the unpacked tree, so this captures them at extraction time:op::notices— afterextract_compressed_tar, scan the tree root (or its lone top-level dir when nostrip_prefix) forNOTICE*/COPYRIGHT*/COPYING*(case-insensitive, regular files only, ≤512 KiB, ≤8 files) and record<cache>/notices/<source-sha256>.json—{schema_version, source_sha256, files:[{name, sha256, text?, base64?}]}(textwhen valid UTF-8,base64otherwise — bytes travel verbatim), selection by metadata before any read, sorted, written once (write-then-rename), idempotent. "Scanned, nothing" is recorded too.lcache::Cache::notices_dir()+ the dir created atat_dir.SourceLoadrecords forWebsources only, keyed by the declaredsha256— the key the sealed attribution manifest already carries per package (sources[].sha256). Local files are project-side and never appear there. Best-effort: a failure logs a warning and never fails the build.mip cache notices <sha256>prints a record.Why this shape
Keying by the archive hash means one record per tarball rather than per package build, stable across rebuilds and arches, and a pure server-side join for build-servers:
sources[].sha256→notices/<sha256>object → optionalnoticesfield onPackageAttribution(schema 1 → 2, additive). No output-tarball or graph changes.Audit backing the scope
