feat(parsers): scan pinned requirements.txt behind --python flag (#672) - #1546
add flag_python (--python) and wire through cli args to parser selection
add requirements.txt parser in src/parsers/requirements-txt.ts:
parse pinned lines of the form name==version
skip comments, blanks, editable installs, unpinned ranges, and unsupported markers
record skipped entries as notes and warnings
set packageref.ecosystem to "pypi" and paths to [["project", name]]
register requirements.txt in lockfilehandler table and scansource
update readdirectdependencynames to extract dependencies from requirements.txt
enforce maintainer experimental rules:
python findings print but are excluded from --fail-on gate calculation (exit 0)
python packages and findings remain excluded from spdx and cyclonedx sboms
--offline refuses to scan python inputs and exits with a clear refusal error
add example fixture in examples/python-requirements/requirements.txt
add unit and integration tests covering parser, experimental exit, offline refusal, sbom absence, and direct relationship classification
what changed and why
adds opt-in python scanning for pinned requirements.txt behind an explicit --python flag, per maintainer steps 3 and 4 of #672. no auto-detection: requirements.txt is only read when the flag is passed, so existing adopters see no behavior change. findings are printed but excluded from the --fail-on gate, and offline mode refuses python inputs instead of reporting clean, because the local advisory db only carries npm advisories. python packages stay out of spdx and cyclonedx because purlforbom remains npm-only, so no pypi purls leak into compliance artifacts.
It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
Added experimental Python scanning with --python for pinned dependencies in requirements.txt, provided directly or found in a project directory.
Scan results report unsupported or unpinned entries that were skipped, and indicate when additional requirements files were not scanned.
Limitations
Python scans do not support offline modes, --only-used, license or maintenance checks, usage analysis, or SBOM output.
Python findings do not affect vulnerability --fail-on thresholds or the command’s exit code, and do not include automated fix targets.
I added experimental, opt-in scanning of pinned Python dependencies from requirements.txt. Scans query OSV using PyPI, report unsupported or unpinned entries, and exclude Python findings from vulnerability exit-code gates.
Changes: Python requirements scanning
Layer / File(s)
Summary
Parse and load requirements.txt src/parsers/requirements-txt.ts, src/parsers/index.ts, src/types.ts, tests/parsers/requirements-txt.test.ts
The parser accepts supported pinned dependencies and reports skipped entries and unscanned files. Lockfile handling carries package data and scan metadata into scan results.
The --python option enables requirements-file discovery. Python mode uses the single-folder scan path, provides Python-specific no-packages guidance, and rejects incompatible options. The CLI help and documentation describe the experimental option.
Scan handling selects PyPI queries and requirements names for direct-dependency classification. Python findings do not affect vulnerability gates or npm fix validation. Skipped dependencies and unscanned files mark scans incomplete.
Python scanning can silently omit dependencies or return success without requested partial reports, and direct-file scans can fail when writing artifacts. Resolve these completeness and file-path failures before merging; remaining guidance and test-isolation issues are narrower.

Explanation
The title follows the required "type: short description" form with the feat type and lowercase text after the colon. It also matches the main change, which adds opt-in scanning of pinned requirements.txt behind the --python flag. The title includes a scope in parentheses and the issue number (#672), which the requirement does not forbid. It has no trailing period.
Full details: Description check
Explanation
The description covers the template's required section, "What changed and why", with a clear explanation of the opt-in --python flag, the parser, and the experimental rules for --fail-on, offline mode, and SBOM output. It refers to issue #672 with "Refs #672". The template has a "Closes #" line, which the author replaced with "Refs #672". That is a different keyword, so the issue is not closed on merge. The lowercase heading "what changed and why" differs from the template's title case, and the "Closes" line is missing from the template structure. These are minor gaps. The description is otherwise complete.

Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.
Preserving PyPI package spelling causes affected-package matching to discard the advisory's fix for equivalent names.
The finding can omit an available fixed version even though the advisory includes one.
This can occur when: A noncanonical pin such as Jinja2==2.4.1 receives a PyPI advisory whose affected package name is jinja2.

Reject --only-used for Python scans until usage detection supports Python.
With --python --only-used, users can get a clean report for a vulnerable package imported in a .py file. The usage scanner skips Python files, so the filter removes the finding. I recommend rejecting this flag combination until Python usage detection is available.

Document the Python exclusion from --fail-on.

Later ratchet runs fail on new Python findings, but the first run does not.
Users get different exit codes for the same Python finding, depending on whether .cve-lite/baseline.json exists. On the first --ratchet run, PyPI findings are excluded from the gate. On the next run, a new PyPI finding makes the command exit 1.
The help text says the exclusion applies to "ordinary scans and initial ratchet runs". It does not say that later ratchet runs still fail on Python findings. Users who read the help text may not expect that result.
Decide which behavior you want, then make the help text match it. Do not filter PyPI findings out of the later ratchet check to fix the mismatch. That change would let a vulnerable PyPI package exit 0. If you keep the current behavior, state in the help text that new Python findings fail later ratchet runs. If you want quieter first runs, print how many Python findings the gate skipped.

The SBOM exclusion tests do not guard anything this PR adds.
These tests call buildCycloneDxBom and buildSpdxDocument directly with Python packages. The exclusion comes from purlForSbom in src/utils/purl.ts. That helper returns null for every ecosystem except npm, and this PR does not change it. The same assertions pass on the base commit, so reverting this PR would not make them fail.
I would add a test that runs handleSingleFolderScan with sbom set against a project that has a requirements.txt and --python enabled. That test covers the path this PR adds: Python loading, then SBOM output with no Python components or vulnerabilities. It fails if a future change lets pypi packages reach the SBOM builders.

Move the requirements.txt scanner to a PR that links an active issue which

Document --python in the scan options.
The --fail-on note explains how Python findings are gated, but the printed option list never names --python. A user who reads --help learns about the exclusion without learning how to turn on Python scanning. FLAG_PYTHON in src/cli/flags.ts is "--python". The README and website/ do not mention the flag either, so the help text is the only place where a user can find it.
The gate note also needs a narrower scope for ratchet runs. Later --ratchet runs still exit 1 on new Python findings (src/scan/single-scan.ts:544-565). Naming only the first run stops readers from assuming the exclusion covers every ratchet run.

A comment line between continuation lines merges two pins into one entry.
When a comment line appears while a continuation is pending, the buffered pin stays in buffer. The next requirement joins to it. For this input, both pins are dropped from packages, and the merged line is reported only as an unpinned warning. A user can miss a vulnerable pinned package because of a comment in the file.
Flush the pending buffer before the comment is recorded. This ends the continuation at the comment, which matches pip's handling of comment lines inside continuations.

Apply credential redaction to every skipped-line branch.
A private index or VCS URL can carry a password in its userinfo part. The parser redacts that part only in the option branch. The editable, environment-marker, unsupported-equality, invalid-version, and unpinned branches store the raw line in warnings and skippedDependencies. For example, -e git+https://user:token@host/repo.git keeps user:token in both arrays. Callers receive these arrays, so the credential can reach any output that prints them.
The current regex also stops at the first @. A password that contains @ leaves a fragment. https://user:p@ss@host becomes https://ss@host.
Route every recorded string through one helper. The pattern [^\s/]*@ stops at the first / after the scheme, so it removes the full userinfo. The existing option-branch test still passes with this pattern.
Add unit cases for an editable line, an environment-marker line, and an unpinned URL line that contain userinfo. Assert on both warnings and skippedDependencies. Include a password that contains @.

With --python --usage, the usage scan runs, but it never reads .py files. Every Python finding that no JS or TS file imports is marked imported: false.

Reject --check-maintenance and --check-licenses when --python is set.
These two checks still read direct dependency names as npm packages, even in a Python scan. In a Python-only project there is no package.json, so the direct name set is empty. The license check then processes nothing and returns no findings. The run can look clean even though no license check happened.
If a project has both a package.json and a requirements.txt, a PyPI package whose name matches an npm direct dependency enters the license check as a direct dependency.
scanEcosystem at src/scan/single-scan.ts:816 already selects pypi for Python scans. The blocks at lines 587 and 597 do not use it. I would reject both flags with --python, following the --only-used check at lines 102-103. The error should tell users to run those checks without --python.

Pass the ecosystem explicitly in the multi-folder scan.
The multi-folder scan calls readDirectDependencyNames without an ecosystem. For a subfolder that has no package.json, the function now searches for a requirements.txt up to four levels deep. If it finds one, the function returns a set of its package names. Before this change, the function returned null in that case. The npm scan can then classify packages from a nested Python file as direct dependencies.
Pass the ecosystem at this call site, as single-scan.ts already does:
After this change, no call in src depends on the implicit Python branch. Remove that branch only after the tests confirm that no caller depends on it.

Use the scan's requirements file for direct-name lookup.
--python scans can read a different requirements file than the direct-name lookup. The lookup has a fixed depth of 4 and accepts a file path only when its name is requirements.txt. The scan follows --search-depth and accepts any file path. Two cases can fail:
With --search-depth above 4, a requirements.txt more than four levels down is scanned but not found by the lookup. The lookup returns null.
With --python prod-requirements.txt, the scan reads that file. The lookup rejects the name and returns null.
I would pass the file the scan selected. Keep the projectPath fallback for npm scans and for the no-file Python case. Also accept any existing file on the Python path.

Exact pins with environment markers are skipped, and the warning does not say what to do next.
A line such as pywin32==306 ; sys_platform == 'win32' has an exact pin, but the parser drops it from the scan. That package is never checked for vulnerabilities. The warning is printed, yet it does not say the package went unchecked, and it does not say how to check it.
Name the consequence and the next step in the warning:
Suggested fix
- warnings.push(`Skipped dependency with environment marker: ${sanitized}`);+ warnings.push(+ `Skipped dependency with environment marker, so it is not checked: ${sanitized}. ` ++ `To check it, remove the marker from this line and scan again.`,+ );
Removing the marker checks the pin on every platform. That can report packages that your target platform does not install, so review the results before you act on them.

Review the replacement and indentation, then test before committing.

Update the environment-marker warning in the requirements parser to state that
the dependency is not checked and tell users to remove the marker and scan
again. Preserve the sanitized dependency text, and note that removing the marker
checks the pin on every platform, so results should be reviewed for platform
relevance.

Thanks @bhushan4work, the parser is in good shape. It goes through the PEP 440 module from #1397 rather than adding its own version handling, and it copes with post releases, epochs, extras, inline comments and pip-compile hash continuations. The flag is explicit, a scan without it is unchanged, and offline refuses as it should.
The work left is mostly about the experimental rules from #672, and in particular the one underneath all of them: Python must never report clean when it didn't look. I tried it on a few small trees and found four places where it does:
A repo with both a JS lockfile and a requirements.txt.examples/direct-fixable plus a requirements.txt, with --fail-on high: without --python it exits 1 on two npm highs. With --python it exits 0, the npm lockfile is never scanned, and nothing says so. Someone adding the flag to an existing CI job would silently lose their npm gate. Please either scan the lockfile too or say plainly that it was not scanned (refusing is fine as well).
More than one requirements.txt. With a/requirements.txt and b/requirements.txt, only a is scanned. Please list the ones that were not scanned.
Lines that were skipped. One pinned line plus two unpinned ones ends with "No known vulnerabilities found" and complete: true in the JSON, while two of three dependencies were never checked. The warnings print, but the final line and the JSON should not say clean.
Flags that can't check Python.--check-licenses prints "No license issues found" for PyPI packages it never looked up, and --check-maintenance and --usage run their npm and JS logic silently. Same for --sbom: it writes a valid SBOM with zero packages and exits 0, which reads as "no components". I'd refuse all four with --python, in src/cli/validate.ts with conflictMessage alongside the existing --only-used and offline refusals, so they fail before the scan starts rather than after the banner.
The other thing is fix guidance. Fix targets are validated against the npm registry, and that step doesn't know the package is from PyPI. django==2.2.0 comes out as "Fix: upgrade to 99.99.99", which is a placeholder package called django on npm, and everything else gets a note like "No versions above 2.19.1 were found for requests on npm". The PyPI fix side is #1516 and stays with us, so for this PR please skip that validation for non-npm findings and don't show a fix target for them yet. The advisory's own fixed version is fine to keep in the findings.
Also: the body says closes #672, but #672 is the umbrella and stays open until Python graduates, so please make it Refs #672. It needs a rebase too: #1515 changed the lockfile selection in src/index.ts and src/parsers/index.ts, and the merge conflicts there. And --python wants a line in the help, docs/cli-reference.md and the README, plus one line in the output saying Python findings are experimental and don't affect the exit code. Right now "1 urgent" followed by exit 0 has no explanation.
The reason will be displayed to describe this comment to others. Learn more.
This keeps PyPI findings out of the gate on ordinary runs, but a later --ratchet run still exits 1 when a new Python finding appears above the baseline. Could Python be left out of every ratchet comparison too? Then the "and initial ratchet runs" wording in the help can go. Also, f.pkg.ecosystem !== "pypi" appears three times now; one helper would keep these from drifting.
The reason will be displayed to describe this comment to others. Learn more.
The multi-folder npm caller doesn't pass an ecosystem here, so a subfolder without a package.json now reads its requirements.txt into the npm direct-dependency names, without --python set. Could the multi-folder path pass "npm", and the argument be required so this can't happen silently?
The reason will be displayed to describe this comment to others. Learn more.
Small one: the flag alone decides this, so the source === "requirements-txt" and packages.some(...) parts of the condition (here and on line 102) can go.

Exercise multi-folder scanning in this regression test.
Users rely on multi-folder scans to classify npm dependencies correctly. I would run runMultiFolderScan with nonempty npm fixtures and assert the names passed to scanPackages or the resulting relationships. This test calls the helper directly, so a wrong ecosystem at the scanner call site would pass unnoticed.

Thanks @bhushan4work, this is a big step. A root lockfile next to requirements.txt now refuses, unscanned requirements.txt files are listed, unpinned lines make the scan partial, the four incompatible flags are refused in validate.ts, later --ratchet runs no longer fail on Python, django==2.2.0 no longer shows 99.99.99, and the help, docs and README cover --python. The tests catch nearly all of it when I take each piece out.
Two places can still say clean without having looked, which is the rule underneath all of this:
An npm project below the root. A root requirements.txt with examples/direct-fixable copied into web/: --python --fail-on high exits 0 and says nothing, where the same tree without --python exits 1 on two highs. Same with a root pinned package.json and no lockfile. The refusal only looks for a lockfile at the root, and --python turns off multi-folder detection, so a nested npm project just isn't seen. Please refuse (or at least name it) for any npm lockfile or pinned package.json the multi-folder search would have found.
Unscanned requirements files still end clean. With a clean package in a/requirements.txt and django==2.2.0 in b/requirements.txt, the warning lists b, but the run ends "No known vulnerabilities found" with complete: true. Could unscanned files add an incomplete-scan diagnostic, the way skipped lines now do?
And a few more:
--check-overrides isn't refused yet; with --python it fails with buildOverrideContext: no package.json, or runs the npm override audit next to the Python scan.
Option lines like --index-url https://... are counted as a skipped dependency and make the scan partial. They aren't dependencies, so I'd ignore them. -r other.txt and -c are real gaps, but should be reported as an included file that wasn't scanned rather than as a dependency.
The verbose table now shows no target for Python, but compact output still says "Fix: upgrade to 5.2.17", and recommendedAction in the JSON, the SARIF message and the HTML report say the same. That version comes straight from the advisory and nothing has checked it, so please drop the "upgrade to" wording for Python on those surfaces too, with a test pinning it. Listing the advisory's fixed version as data is fine.
The refusal blocks in single-scan.ts (around 108-114) can't be reached any more since validateOptions refuses first, and they repeat its message. Please remove them and move their three tests to validateOptions.
ecosystem === "pypi" is still written out in eight places across the printers, fix-commands and scanner. One helper (or isPep440Ecosystem, which main already has) would keep these together. If the parser emits OSV's own PyPI spelling, the case mapping in osv-advisory-source.ts can go too.
The PR body still says closes #672; please make it Refs #672.

Thanks @bhushan4work, both of the big ones are fixed. A root requirements.txt with examples/direct-fixable copied into web/ now refuses and names web/package-lock.json, and the same goes for a pinned package.json with no lockfile. Unscanned requirements files make the scan partial, with complete: false and exit 3 under --incomplete-policy error. --check-overrides is refused, --index-url lines are ignored, -r and -c show up as included files that weren't scanned, the "upgrade to" wording is gone for Python on every surface, the dead refusal blocks are out, and isPep440Ecosystem is used throughout.
A few things before this can land:
One test fails, here and in CI (build and Node 22 floor), and it's pointing at a real problem: a Python finding with no fixed version now gets no guidance at all instead of "No known fix exists". See the inline note.
npm output changes without --python. The new skipped-dependency diagnostic fires for the npm package.json fallback too, which has always listed unpinned dependencies there. A package.json with axios: 0.21.1 and lodash: ^4.17.0 and no lockfile exits 0 under --incomplete-policy error on main and exits 3 here, with complete flipping to false. One of the conditions we agreed for Python was that no existing user's output changes, so please limit it to requirements files. If marking that npm case partial is worth doing, it deserves its own issue.
The PR body still ends with closes #672, which would close #672 on merge. Please make it Refs #672.
Two tests that don't catch what they cover. Forcing the HTML report back to non-Python wording leaves the HTML test green, since the row never contained "upgrade to" anyway; asserting the Target cell has no fix hint for 1.26.17 would pin it. And removing the nested pinned package.json check (the web/package.json, no lockfile case) leaves everything green, so that case needs a test.
Smaller ones, take or leave: in checkMixedRepoRefusal the code throws inside the try and then catches its own error by message, so narrowing the try to the loadFromPackageJson call would be cleaner. pip accepts -rother.txt with no space, which the "skip anything starting with -" rule drops silently. And Python runs still print npm-only notes ("Installed node_modules contents are not verified") and "OSV + npm registry advisory" as the source.
The reason will be displayed to describe this comment to others. Learn more.
This returns null for every PyPI finding before the existing branch that says no fix exists, so a Python finding without a fixed version loses "No known fix exists" and ends up with nothing. Could it only return null when the advisory does name a fix version? summarizeNextAction has the same issue with "".
The reason will be displayed to describe this comment to others. Learn more.
Thanks @bhushan4work, everything from the last round is in. A Python finding with no fixed version says "No known fix exists" again, in the JSON and the next-action text. The skipped-dependency diagnostic only fires for requirements files now, so the npm package.json fallback (axios 0.21.1, lodash ^4.17.0, no lockfile) exits 0 under --incomplete-policy error with complete: true exactly like main, and its output is identical to main. The body says Refs #672, the HTML test pins the Target cell, and the nested web/package.json case has its test. The smaller ones are done too: the try is narrowed, -rother.txt counts as an included file, and Python runs show OSV as the source without the node_modules note. The earlier fixes all still hold.
Three things left:
The new scan tests write their mock advisories into the real cache.noCache: true only skips reading the cache, saving still happens, so running the suite drops the two mocked records (PYSEC-2023-192, PYSEC-2020-001, with the test's own summaries) into ~/.cache/cve-lite/osv-vulns.json on the machine running it. A real scan that hits those ids later gets the fake record back. Passing a temp cacheDir in those options, the way the other scanner tests do, fixes it. See the inline note.
A capitalised package name loses its fix version.Flask==2.0.1 finds both advisories but reports "No known fix exists for Flask", while flask==2.0.1 gets 3.1.3. pip treats names case-insensitively and with -, _ and . as the same, and plenty of requirements files write Flask or Django, so the fixed-version lookup needs the names normalised before it compares them with the advisory's package name.
Passing the requirements file itself with --ratchet crashes.cve-lite req.txt --python --ratchet stops with ENOTDIR: not a directory, mkdir 'req.txt/.cve-lite'. Main doesn't accept a file path at all, so this is new with the file input. Using the file's folder for the baseline, or refusing the combination with a clear message, would both be fine.
Small one, take it or leave it: the HTML report still links Python packages to npmjs.com (https://www.npmjs.com/package/Flask), and the project path node gets a link too.
Once those are in, could you also resolve the CodeRabbit threads that are already addressed? Most of them are, and they're still open because its review is paused.
The reason will be displayed to describe this comment to others. Learn more.
noCache stops the cache being read but the scan still saves to it, so this writes the mocked urllib3 and six records into the real ~/.cache/cve-lite. Could these tests pass a temp cacheDir (and clean it up after), here and in the other scan calls in this file?
The reason will be displayed to describe this comment to others. Learn more.
The name is kept exactly as written, and the fixed-version lookup compares it with the advisory's package name as-is, so Flask==2.0.1 ends up with "No known fix exists" while flask==2.0.1 gets 3.1.3. Normalising both sides the way pip does (lowercase, with runs of -, _ and . treated as one) when comparing would fix it, and keeping the original spelling for display is fine.
The reason will be displayed to describe this comment to others. Learn more.
When the input is the requirements file itself, --ratchet then tries to create .cve-lite inside the file path and fails with ENOTDIR. Could the baseline use the file's folder, or could this combination be refused with a clear message?

- Add requirements.txt parser in src/parsers/requirements-txt.ts:
- Parse pinned lines of the form name==version
- Skip comments, blanks, editable installs, unpinned ranges, and unsupported markers
- Ignore option lines (e.g. --index-url, -i, -f) without marking scan partial or skipped
- Report included files (-r, -c, --requirement, --constraint) as unscanned files
- Redact URL userinfo credentials across all skipped-dependency branches and warnings
- Record skipped entries as notes and warnings
- Set PackageRef.ecosystem to "pypi" and paths to [["project", name]]
- Send "PyPI" in OSV query payload while keeping internal ecosystem as "pypi"
- Register requirements.txt in LockfileHandler table and ScanSource
- Require ecosystem argument in readDirectDependencyNames to prevent non-npm leaks
- When --python is set, refuse if root or nested JS/TS lockfile or pinned package.json is present
- Disallow incompatible flag combinations (--python with --only-used, --offline, --check-licenses, --check-maintenance, --check-overrides, --usage, --sbom) in CLI validation
- When multiple requirements.txt exist or included files are referenced, record unscannedFiles and mark scan incomplete with UNSCANNED_REQUIREMENTS_FILE diagnostic
- Report partial scan when dependencies are skipped or requirements files are unscanned
- Skip npm fix-target validation for pypi findings
- Exclude pypi findings from ratchet comparisons using shared isGatableFinding helper
- Drop "upgrade to" wording for python findings on compact, json, sarif, and html surfaces
- Consolidate ecosystem checks to isPep440Ecosystem helper
- Add notice that Python findings are experimental and do not affect the exit code
- Enforce maintainer experimental rules:
1. Python findings print but are excluded from --fail-on gate and ratchet calculations (exit 0)
2. Python packages and findings remain excluded from SPDX and CycloneDX SBOMs
3. --offline refuses to scan Python inputs and exits with a clear refusal error
- Document --python and --fail-on Python exclusion in CLI help, README, and documentation
- Add example fixture in examples/python-requirements/requirements.txt
- Add unit and integration tests covering parser, mixed-repo refusal, multiple requirements.txt, ratchet exclusion, skipped completeness, surfaces formatting, and validation

Users depend on accurate requirements scans, and this 147-line parser makes changes harder to review. I suggest extracting the continuation pass and other distinct parsing steps into helpers, as the path instruction requires.

Keep Python findings out of npm guidance.
If requirements.txt changes between the two reads, a no-fix Python finding can be classified as transitive. Its JSON recommendation then tells users to run npm ls, which cannot inspect Python dependencies. I suggest handling this case before the npm fallback.

Record dependency directives before ignoring options.
With --requirement followed by a tab, users can get a clean scan while dependencies in the included file remain unchecked. --incomplete-policy error also passes. I recommend recognizing pip’s whitespace and compact forms and recording included files and skipped editable installs.
As per path instructions: “Flag: any change that could make a vulnerable package scan clean or exit 0 under --fail-on.”

add flag_python (--python) and wire through cli args to parser selection
add requirements.txt parser in src/parsers/requirements-txt.ts:
register requirements.txt in lockfilehandler table and scansource
update readdirectdependencynames to extract dependencies from requirements.txt
enforce maintainer experimental rules:
add example fixture in examples/python-requirements/requirements.txt
add unit and integration tests covering parser, experimental exit, offline refusal, sbom absence, and direct relationship classification
what changed and why
adds opt-in python scanning for pinned requirements.txt behind an explicit --python flag, per maintainer steps 3 and 4 of #672. no auto-detection: requirements.txt is only read when the flag is passed, so existing adopters see no behavior change. findings are printed but excluded from the --fail-on gate, and offline mode refuses python inputs instead of reporting clean, because the local advisory db only carries npm advisories. python packages stay out of spdx and cyclonedx because purlforbom remains npm-only, so no pypi purls leak into compliance artifacts.
