…urity claim - Remove the "Security assessment output formats" section — dfetch check's SARIF and Code Climate outputs are CI integration features, not part of dfetch's security model - Fix the Threat Models section: toctree now contains only the two actual threat models; the misleading "each page is generated from Python modules" claim (which did not apply to compliance_track or control_register) is corrected - Give CRA Compliance its own toctree for compliance_track and control_register - Move security_pipeline to a subsection of Further Reading (hidden toctree keeps Sphinx happy); removes it from the main narrative flow - Trim Further Reading: shorter descriptions, remove the EU Blue Guide entry and the Code Climate / CycloneDX / SARIF format references https://claude.ai/code/session_01MoaUFm7mhFxEFuk14NKPh2

WalkthroughDocumentation-only updates across three security/compliance explanation pages: pins OSCAL version to 1.1.2 (noting NIST released 1.2.2 in April 2026 with migration pending), revises CRA non-commercial exemption framing with specific article/recital citations, expands detailed ECR control explanations and gap descriptions, and restructures security.rst with new documentation pipeline subsection and refined reference lists.

Corrections identified by compliance review against CRA (EU) 2024/2847, BSI TR-03183-1, and ENISA/NIST references: - Article 13(5) misidentification (critical): replace with correct framing — Article 13(5) covers manufacturer documentation obligations, not open-source or voluntary compliance. The note and classification table now state that dfetch has no legal obligation under the CRA and that downstream integrators must fulfil their own Article 13 duties. - Recital 18 imprecision: the opening note now cites Article 3(1) (the operative scope provision) alongside Recital 18 (interpretive context). Recitals are preamble text, not binding law. - Legal basis table: replace "Article 3(14), Recital 18, Article 13(5)" with the correct chain: Article 3(1) (scope), Article 3(14) (open-source software steward definition, for reference), Recital 18. - Voluntary alignment row: remove incorrect Article 13(5) citation; state plainly that the document is voluntary. - "Art. 2(a)-(m)" corrected to "Annex I Part I (a)-(m)": Article 2 of the CRA is the scope article, not the essential requirements. - Part II §4 N/A: rewritten without citing Recital 18 as the operative basis; explains the obligation falls on commercial manufacturers only. - ISO/IEC 27005 vocabulary claim removed: BSI TR-03183-1 is the actual source of the Mitigate/Accept/Transfer vocabulary; ISO/IEC 27005 uses different terminology (Retain/Tolerate/Treat/Share/Terminate). - prEN 40000-1-2 title updated to reflect SDL focus confirmed by CEN/CLC work-programme sources; marked as working title. - OSCAL 1.1.2 pinning noted in all three files: NIST released 1.2.2 in April 2026; the docs now clarify 1.1.2 is the pinned version. https://claude.ai/code/session_01MoaUFm7mhFxEFuk14NKPh2
CRA Annex V technical documentation map (new section): - Added between Classification Decision and Applicable Standards - Maps each of the six Annex V elements to the corresponding dfetch artifact or section, as a convenience for downstream Article 13 conformity assessments ECR-B SO.SecureDefaultConfiguration gap was blank despite ⚠ Partial: - Documents the actual gap: integrity hash (C-005) is opt-in; manifest entries without an ``integrity`` field are fetched without verification ECR-C SO.UserUpdateNotification — C-040 was wrongly mapped: - C-040 is "test result attestation on source archive", not an update notification mechanism - Reclassified as N/A with rationale: dfetch is a passive CLI tool with no persistent process; proactive in-product notifications are not technically feasible without architectural change - Note below table rewritten: clarifies that SUM-1/SUM-2 are satisfied by PyPI+OIDC publishing and the CVE release gate (C-043), and explains the N/A reasoning for LNM-1 in detail ECR-D SO.AccessControl — framing was misleading: - C-006 (non-interactive VCS) and C-036 (credential redaction) are confidentiality controls, not authentication/authorisation mechanisms - Gap now states explicitly that dfetch has no native access control layer and delegates entirely to the VCS server and host OS - SO.AccessControlReport gap note updated: C-045 detects plaintext transport but does not log events https://claude.ai/code/session_01MoaUFm7mhFxEFuk14NKPh2
…rsions dfetch check and dfetch environment both call newer_version_available() in dfetch/util/github_version_check.py, which polls the GitHub releases API and notifies the user if a newer release exists (suppressed in CI). - Restore SO.UserUpdateNotification as ✓ Implemented with direct reference to github_version_check.py; note CI suppression in Gaps - Move C-040 (test result attestation) to ECR-A where it belongs: attesting that CI tests passed before release is a vulnerability management control, not an update notification mechanism - Correct the note below the table: replace the wrong "N/A — passive CLI tool" explanation with an accurate description of the check https://claude.ai/code/session_01MoaUFm7mhFxEFuk14NKPh2
ECR-E SO.DataTransmittedConfidentiality (C-005 removed): C-005 is an integrity hash, not a confidentiality control. Only C-045 remains; status downgraded to ⚠ Partial since C-045 warns but does not enforce HTTPS/SSH — enforcement is delegated to the VCS client. ECR-E SO.ComAuth (C-003, C-004 removed): C-003 (archive symlink validation) and C-004 (archive member type checks) are archive-extraction safety controls, not channel authentication. They are already correctly placed in ECR-J. SO.ComAuth now references only C-045 with a gap note: server authentication is delegated to the OS trust store and VCS client; status ⚠ Partial. ECR-F SO.DataTransmittedIntegrity (C-003, C-004 → C-005): C-003/C-004 validate archive contents after download — that is archive extraction safety, not transmission integrity. C-005 is the actual end-to-end integrity control (HMAC hash over downloaded archive content, opt-in). Gap updated: C-005 applies to archive sources only; git/svn rely on VCS object integrity and TLS/SSH channel integrity. ECR-I SO.LimitExternalImpact (blank gap filled): ⚠ Partial with no documented gap was inconsistent. Gap now states: no connection timeout or rate limiting on VCS operations. ECR-J SO.ReduceAttackSurface (blank gap filled): ⚠ Partial with no documented gap was inconsistent. Gap now states: no domain/URL-scheme allowlist on manifest remote URLs; no network operation timeout enforced. ECR-L SO.LogSecurityRelevantActivities (C-036 removed): C-036 (persisted-metadata credential redaction) is a data-protection control, not a security logging control. Controls column set to "—"; gap updated to accurately describe the logging situation: no persistent structured log, no audit trail of fetch operations. https://claude.ai/code/session_01MoaUFm7mhFxEFuk14NKPh2

In `@doc/explanation/compliance_track.rst`:
- Line 178: Correct the documentation in compliance_track.rst to accurately
reflect the actual implementation details: (1) In the ECR-C section around line
207-210, clarify that the CI environment variable suppression is implemented in
dfetch/commands/check.py (lines 107-110) which conditionally calls
newer_version_available() when CI is not set, not in github_version_check.py
itself, and note that the dfetch environment command does NOT suppress the
version check; (2) In the ECR-I/J timeout gap section around lines 289 and
304-305, revise the statement "No timeout on VCS operations" to specifically
scope it to git and svn subprocess operations only, and add clarification that
archive HTTP operations do implement timeouts (15 seconds for reachability
checks, 60 seconds for downloads) as implemented in dfetch/vcs/archive.py.

ECR-C SO.UserUpdateNotification — CI suppression scope:
The suppression guard (os.environ.get("CI")) is in check.py line 102,
not in github_version_check.py. dfetch environment calls
newer_version_available() unconditionally with no CI guard. Both the
row gap column and the note below the table are corrected.
ECR-I SO.LimitExternalImpact — timeout gap scoped to git/svn only:
archive.py implements timeouts (15 s reachability, 60 s download via
_http_conn). The gap now correctly states that only git and svn
subprocess calls have no timeout.
ECR-J SO.ReduceAttackSurface — same timeout correction applied.

SARIF and Code Climate outputs are CI integration features, not part of
dfetch's security model
threat models; the misleading "each page is generated from Python modules"
claim (which did not apply to compliance_track or control_register) is corrected
keeps Sphinx happy); removes it from the main narrative flow
and the Code Climate / CycloneDX / SARIF format references
