the index was ported from a prototype with per-node `RWMutex` lock upgrading and JSON marshalling. Its only consumer (`archive.Resolver`) builds it sequentially during extraction and then only reads it, so neither was used. `lock.go` also compared method-value pointers to tell the read lock from the write lock, which can't distinguish lock instances.
removed the locks, the upgrade and retry paths that existed only for concurrent writers, and the JSON methods and their test. The radix logic is unchanged, and the README now points at `archive.Resolver` rather than a nonexistent `archive.Index`.

the SPDX writer only kept relationships whose `From` is a package, so the `file CONTAINS package` edges the archive task records were dropped. For anything that isn't java (npm in a tgz, python in a zip) that edge is the only thing saying which archive a package came out of.
SPDX now also writes `CONTAINS` from a file to a package. The file end is always in the document, since `toFiles` covers every coordinate a relationship names. Other file-side relationships (e.g. binary's file `DEPENDENCY_OF` package) are still dropped as before.
CycloneDX is unchanged: it has no file components to hang the edge on, and war-to-jar structure reaches it through the java `DEPENDENCY_OF` parity fix.

SPDX wrote `FileName` from `RealPath` only, so two archives' `META-INF/MANIFEST.MF` became two SPDX files with the same name and nothing saying which archive each came from. Worse, a consumer reading just the name would take a nested file for one at that path in the scan root.
- a file inside an archive is now named by its full chain, using the same `:` convention and escaping as `ArchivePath` / java's `VirtualPath`: `app.war:WEB-INF/lib/a.jar:META-INF/MANIFEST.MF`
- `FileComment` gains an `archivePath: ...` line (next to the existing `layerID: ...`, one per line), so decoding recovers `ArchivePath` and the entry's own `RealPath` without guessing where the chain ends
- files outside archives are unchanged

`isArchiveMetaPom` was an unconditional `strings.Contains(path, "META-INF/maven/")`, so the pom cataloger dropped real poms everywhere, even with the feature off: exploded wars (`WEB-INF/classes/META-INF/maven/...`), test fixtures under `src/test/resources`, source tarballs. That's a regression on the default path.
the skip exists because inside a jar those poms are raw build copies that java already covers from `pom.properties`. So it now applies only when the traversal on the context is a java archive. Outside one, or inside a tarball java doesn't describe, the poms are cataloged as before this PR.

the legacy recursion links a nested jar to the jar that holds it: a `DEPENDENCY_OF` edge from inner to outer, and `JavaArchive.Parent` on the inner package. Inside an extracted archive java called `parse(ctx, nil)`, so both went away as soon as the feature was on. What replaced them was `file CONTAINS package`, which SPDX and CycloneDX drop, so those formats lost all war-to-jar structure.
- `archive.Traversal` gains `Parent` and `Packages` (the packages found describing that archive, filled in by the task after its sub-pipeline runs)
- java picks the enclosing jar's main package from the parent traversal (the one whose virtual path is the archive's own; pom-derived aux packages carry a suffixed one) and passes it to `parse`, then sets `Parent` the same way the legacy path does

with nested cataloging on, java leaves root-level archives to the archive task, so a root `app.jar` package only exists once that task has run. With the default `FilesOwnedByPackageSelection` the root file catalogers ran in an earlier group, never saw the package, and `app.jar` got no file metadata or digests. It did get them with the feature off.
- in owned-by-package mode the groups are now packages, then the archive task, then the root file tasks. Other modes are unchanged
- the file tasks merge their results into the SBOM instead of replacing the maps, since the archive task has already written nested files into them

with `FilesOwnedByPackageSelection` the file catalogers take every package location in the SBOM and look it up by `RealPath` in the resolver they were given. Inside an archive, the java package's location is the archive itself *in its parent's frame* (`WEB-INF/lib/dep.jar`), so the sub-pipeline looked that path up inside `dep.jar`'s own resolver: a miss, or an unrelated same-named entry by coincidence. At the root, coordinates from inside archives were looked up against the scan root the same way.
`coordinatesForSelection` now keeps only coordinates whose `ArchivePath` matches the current frame (the traversal's `ContentsArchivePath()`, or blank at the root).

a read error while copying one entry (a zip CRC mismatch, a corrupt deflate stream) was returned from `add`. That aborted the walk, and `Extract` threw away every entry already stored. So a large war with one damaged, irrelevant entry produced zero packages with the feature on, while java's legacy path (which reads only the entries it needs) still cataloged it.
- a read error on one entry now drops that entry and marks the resolver truncated (`entry "x" could not be read: ...`), and the walk continues
- if the stream itself breaks partway (a truncated `.tar.gz`), whatever was read before the break is kept and the archive is truncated. With nothing read it is still an error, as before
- disk limit and decompression budget errors still stop the walk

the archive's `CONTAINS` edges were built from every coordinate in the sub-pipeline's scratch SBOM, which gets one of two things wrong:
- with the default `FilesOwnedByPackageSelection`, nothing records the nested archives as files, so the archive-to-archive chain was missing and grandchild packages hung off coordinates with no incoming edge
- the scratch SBOM also holds coordinates from the parent's frame, most notably unknowns recorded at the archive's own coordinates (e.g. a jar with no manifest). Those turned into `x.jar CONTAINS x.jar`
edges now go to the nested archives found in it (always, whatever the file selection), plus coordinates whose `ArchivePath` is this archive's own chain, i.e. files that are actually inside it. The walk reuses that one discovery pass for the recursion.

with nested cataloging on, java stops recursing into jars itself (the task owns recursion) and its own "nested archives not cataloged" unknown is suppressed. The task then just returned at the depth bound. So `MaxDepth: 1` on a war silently found fewer jars than leaving the feature off, and nothing in the SBOM said so.
at the bound, every archive that sits there (by content sniff) is now recorded as a "nested archive not cataloged: the nested archive depth limit was reached" unknown. The CLI description for `nested-archive-max-depth` notes that it replaces java's unbounded jar-in-jar recursion.

the limiter bounds what's held *at once*, and each archive gives its bytes back when it's released. So a recursive bomb (42.zip shape) never trips a limit: every level fits on its own, and the scan just runs for effectively forever. Capping each archive at N× its own size wouldn't help either, since every level of such a bomb is high-ratio, so the work still grows about N-fold per level.
- each top-level archive gets one decompression budget of `max(100 × its size, 1 GiB)`, spent by every archive nested under it at any depth
- the budget is attached to the context when the walk enters a top-level archive, so `Extract` picks it up without a signature change
- once it's spent, the archive being extracted is truncated with a "possible decompression bomb" unknown and the walk moves on. The next top-level archive starts fresh
real trees (a war of jars, a layer of tarballs) expand a few times over, well under the ratio.

`put` had no per-entry cap, unlike the legacy java path which capped every file at 2 GB through `intFile.SafeCopy`. At depth 1, one entry of an overlapping-entry zip bomb could decompress all the way to the 100 GB disk limit before anything stopped it.
- entries are now read through the same 2 GB cap (`intFile.PerFileReadLimit`, now exported). An entry over it is dropped after cap+1 bytes and the rest of the archive is still extracted
- `Resolver` gains `TruncatedReason`, so the truncation unknown says what happened ("an entry larger than 2.0 GiB was skipped", or the existing disk-limit text) instead of always blaming the limits

a negative `MaxDepth` really was unbounded, and nothing noticed an archive nested inside a copy of itself. A zip quine at `-1` recursed until memory, disk or file descriptors ran out, running the full sub-pipeline at every level.
- the walk keeps a stack of the digests of the archives it's inside, and an archive identical to one of them is recorded as an unknown instead of being entered
- negative depth now stops at 16 levels (docs and CLI description updated)
- cancellation is checked between candidates, so a cancelled scan stops walking instead of finishing the archive tree
the three unknown-recording blocks in `processArchive` became a one-line helper to stay under `funlen`.

`identifyFormat` accepted any extractor mholt identified, which put the 7z and rar decoders (`bodgit/sevenzip`, `rardecode`) on untrusted input with no test coverage. Only zip, tar and compressed tar are opened now, until other formats are deliberately supported.
This also fixes java resource adapters: a `.rar` that is really a zip used to be identified by name as RAR and fail to extract. An unsupported identification now falls through to the zip end-of-central-directory check, so it's read as the zip it is.

sub-pipeline catalogers were already run under `runTaskSafely`, but extraction wasn't: the zip, tar and compressor decoders run on untrusted bytes, and a panic in one unwound the whole walk and failed `CreateSBOM` with "failed to run tasks".
- `processArchive` recovers and returns the panic (with its stack) as an error at the archive's coordinates, so it becomes an unknown and the sibling archives are still cataloged
- `Extract` now defers `Cleanup` on failure instead of calling it on each error path, so a panic no longer leaks the limiter charge or the spill file

each `ArchivePath` segment came from `loc.Path()`, so it was the link path when an archive was reached through a symlink and the real path otherwise. That depended on how discovery happened to find the archive. The package location said `store/3f9a1c` while the files inside the same jar were recorded under `...:app/lib/json-simple-1.1.1.jar`, so a consumer couldn't join a package to its files by prefix.
The chain for extracted files is now built from `RealPath`. `Traversal.Location` still carries the access path, so java's name check and `VirtualPath` metadata behave the same as before. The field comment and schema now say every segment has links resolved.

`discoverArchives` collects MIME hits first, and those are bare real paths. When the glob pass then found the same file through a symlink, it was dropped as a duplicate along with its access path. Java decides whether to describe an archive by its name, so a content-addressed jar (`store/3f9a1c`, linked from `lib/json-simple-1.1.1.jar`) was extracted but produced no package. This is the pnpm / nix / bazel layout.
When deduping, the candidate now takes the first location that carries an access path.

`:` was escaped as `%3A`, but `%` itself wasn't, so an entry named `a:b.jar` and one named `a%3Ab.jar` got the same `ArchivePath`. Their contents then collide in `FileMetadata` / `FileDigests` (last writer wins) and share artifact IDs.

syft-json output wasn't reproducible for nested archives. `AllCoordinates()` comes from map iteration, and the coordinate and location sorters ignored `ArchivePath`, so the same path in two archives (e.g. `META-INF/MANIFEST.MF` in two jars in a war) compared equal and came out in random order. Package locations had the same problem.
- `ArchivePath` is now the final tiebreak in `LocationSorter`, `CoordinatesSorter` and the `CoordinateSet.ToSlice` fallback
- `Location.Equals` and `Location.String` include `ArchivePath`, which matches `Coordinates`, since the same path in different archives is a different file

- java's embedded `ArchiveSearchConfig` and `WithArchiveTraversal` are deprecated; `WithMaxParentRecursiveDepth` replaces the latter's other half
- `CreateSBOM` now rejects `MaxDepth`, `MaxMemoryBytes` or `MaxDiskBytes` set on java's copy with an `invalid configuration` error
- the top-level `IncludeIndexedArchives` / `IncludeUnindexedArchives` are overlaid onto a copy of java's config, and win when they differ from the default. Callers who only set java's copy see no change

* fix(java): resolve Groovy 4+ group IDs to org.apache.groovy
Groovy 4.0 moved from the Codehaus coordinates (org.codehaus.groovy) to the
Apache Software Foundation (org.apache.groovy). JARs that ship no pom
metadata fall through to the static artifact-to-group map, which carries the
3.x-era org.codehaus.groovy entries for the whole groovy family, so 4.x
artifacts were attributed to an obsolete group even though their manifest
identifies the Apache vendor.
Where the static map attributes an artifact to the historical group, a
major-version migration resolves groovy 4.x and newer to org.apache.groovy,
while 3.x and earlier keep their historical group. The Eclipse-hosted
groovy-eclipse-* artifacts, which share the prefix but kept their Codehaus
coordinates, are excluded.
Fixes#5311

* refactor(java): share version-aware groovy group ID lookup with CPE generation
- move the artifact-to-group lookup behind `cpegenerate.ArtifactIDToGroupID(artifactID, version)` so the PURL and CPE paths agree; the exported mutable map is now unexported
- version-dependent entries are expressed as a `groupIDMigration{before, after, atMajor}` (groovy moved to `org.apache.groovy` at 4.0); unconditional entries, including `groovy-eclipse-*` and apache-only 4.0+ modules, stay in the plain map
- add apache-only modules (`groovy-ginq`, `groovy-contracts`, `groovy-callsite`, ...) that otherwise took the group from their per-module `Automatic-Module-Name`
This changes CPEs for pom-less groovy 4+ jars (all real ones): vendors are now `apache` (e.g. `cpe:2.3:a:apache:groovy:4.0.33`) instead of `codehaus`, matching the PURL, jars with pom metadata, and NVD.

* build(deps): bump go-make to v0.8.1
Picks up golangci-lint 2.13.2 (built with go1.27) in place of 2.11.4 (go1.26).
The old build panics outright on a go1.27 GOROOT with "file requires newer Go
version go1.27", and an older mise-shim build fails the quieter way: it loses
type info and reports zero findings with exit 0, so a ruleguard run comes back
green without having evaluated anything.
Also folds in what the newer linter flags:
- `reflect.Ptr` -> `reflect.Pointer` in three files, applied by --fix
- `tw.CellFormatting{MergeMode: ...}` -> `tw.CellMerging{Mode: ...}` in the
cataloger info table, for a staticcheck SA1019 deprecation
Note the deprecation text names `CellConfig.CellMerging.Mode`, but the field is
`CellConfig.Merging`; `CellMerging` is the type. That command path has no test
coverage, so the swap was checked by rendering the same hierarchical-merge table
both ways and diffing: byte identical.

* chore(lint): tune goconst for data tables
goconst got stricter in golangci-lint 2.13 and now counts strings in map
literals and struct fields, which lights up every lookup table in the repo. It
was already enabled, so this is main going red on a linter bump rather than
anything new in the tree: 101 findings, and the default threshold of 3 means a
vendor name appearing in three rows of a table reads as a magic constant.
Raising `min-occurrences` to 5 takes that to 14. The rest split by whether the
repeated string is data or an actual constant:
- `cpegenerate` is excluded by path. It maps artifact names to vendors,
products, and maven group ids, and repeats strings 35, 83, even 293 times, so
no threshold reaches it. Hoisting those would trade a readable table for
indirection.
- the two SBOM fixture builders in `format/internal/testutil` get a
function-level nolint each. The repeated names and versions are what the
golden files assert against.
- `mysql-cluster` and `php` were genuine repeated literals and are now
constants.

Now `testutils.MeasureAlloc`, at the repo root so `internal/spillbuf` can reach

* chore(lint): add ruleguard rules for overflow and swallowed EOF
Two rules out of the recent unbounded allocation work (#5187, #5195, #5267,
#5291, #5292, #5293, #5294).
`noOverflowingBoundsCheck` flags `offset + size > limit` (and <, <=, >=) where
an operand is unsigned, neither addend is constant, and the operands are at
least 32 bits. Unsigned addition wraps, so an offset out of a file header can
carry the sum past the wrap point and pass a check it should have failed. The
fix is to subtract against the limit instead. Constant addends are excluded
because `pos+4 <= uint32(len(buf))` is the normal way to step a cursor, and the
32-bit floor drops nibbles widened for a comparison. Would have caught four
sites across #5195 and #5291.
`noSwallowedEOF` flags `return nil` / `return nil, nil` on an io.EOF check. The
caller gets a zero value it cannot tell from real data, and anything decoding a
fixed-size struct off it parses the padding as content. That is the shape behind
#5186.
Both decide from the expression alone, and writing the fix deletes the pattern,
so neither needs a suppression anywhere in the tree. That was the bar: rules for
the allocation and decompression classes were tried and dropped, because the
bound they look for lives in a preceding statement (or, for a decompressor
constructor, always downstream), so no correct implementation can silence them.
That would have meant ~15 permanent nolints on code that is already right. The
rules here that do work don't judge whether a bound exists, they route to a
wrapper that takes one: noDirectTempFiles, noDirectELFOpen.

* test: pin allocation budgets on the alpm, deb, and changelog bounds
The bounds added for #5292, #5293 and #5294 are asserted by the error they
return. That keeps passing if the bound is removed and something else rejects
the input later, which is the failure these were written for. Each of these
measures bytes instead, and proves the fixture is really a bomb first so a
fixture that quietly stops being one fails rather than passing.
- alpm mtree: 16MB of newlines, well inside the 64MB byte cap, costs 16.5GB
uncapped against 238MB with maxMtreeLines. That 16.5GB is the measurement the
line cap was added for and it was recorded only in the commit message. Note
what the cap actually buys: 300k entries still cost a few hundred MB, per
concurrent cataloger.
- deb members: 1.28GB against 392KB. Both arms read with io.ReadAll on purpose,
since the stream itself never holds much whatever the cap says; what the cap
protects is a consumer that buffers, and the real one is a tar reader building
entries.
- snap changelog: 1.28GB against 175KB. This one has no explicit cap at all. It
is held by bufio.Scanner refusing a token past MaxScanTokenSize, which is
incidental, so switching to io.ReadAll or a bufio.Reader to pick up long lines
would remove it silently.
Nothing added for the kernel module reader: its copy is already
io.Copy(tempFile, io.LimitReader(rc, max+1)), so peak disk is bounded by
construction and heap is streaming. A heap budget would assert the wrong
resource, and the three existing subtests cover the cap, at-cap fidelity, and
spill cleanup.

* test: pin allocation budgets on the ai and alpm byte caps
Follows the same pattern as the alpm line cap: measure bytes, and prove the
fixture is really a bomb first so one that quietly stops being a bomb fails
rather than passes.
- safetensors: 252MB against 2.6KB. The existing over-cap case deliberately
omits the body, since the guard rejects on the declared length before reading
anything. That is the right test for the guard but it would keep passing if
the check moved after the read, so this one delivers the bytes.
- gguf: 268MB against 168MB. copyHeader io.Copy's whatever it is handed, so
maxHeaderSize holds only because every caller wraps the reader first. This
pins that the limit is where the bound lives, so dropping the wrapper at a
call site fails here.
- alpm byte cap: 740MB against 132MB, the counterpart to the line cap budget.
Worth knowing for anyone writing the next one of these: a single enormous line
does not exercise the alpm byte cap. go-mtree runs its own bufio.Scanner and
refuses a token past 64KB, so that fixture fails as "token too long" before the
byte cap is consulted. The fixture here uses ordinary 1KB lines, enough of them
to pass 64MB while staying under the 300k line cap, so the byte cap is actually
the thing under test.
