How do I write a SWHID that cites an exact revision, file path and line range, and which qualifier combinations are valid?

A qualified SWHID adds ;key=value qualifiers to a core id. lines= (1-based, inclusive) or bytes= (0-based) are valid only on content, and at most one is allowed. origin, visit, anchor and path say where the object was seen; anchor requires path and visit requires origin. The canonical order is origin, visit, anchor, path, lines/bytes. The contradiction the producer found is real in the text it pinned (91af30d, which diverged from main): the rule said path was invalid on content while the examples used it. It was reported (issues #69, #71) and fixed on main by commit 45f8de0 (2026-09-19): path is valid only for content or directory. That fix also makes path on rev, rel and snp invalid, and implementations ignore invalid qualifiers. Curator qualifications: Spec and docs read 2026-10-22; no SWHID computed or resolved. Whether the ISO/IEC 18670 text carries the old or new sentence is unknown (ISO text paywalled). Curator amendment CA-AM-0051 (2026-10-22): Corrected and extended (curator, after C3R-0516). (1) #69 is an issue (closed completed 2026-09-19T09:47:28Z); #71 is the pull request that changed the sentence (merged 09:47:27Z). They are not 'issues #69, #71'. (2) The released edition: tag v1.2 (release 2025-11-07) resolves to a9fdba9 (2025-04-23). Its 6.Qualified_identifiers.md (sha256 74be3259) carries the old sentence ('only valid when the object type is not content'), the same text as the producer pin. The corrected rule ('content or directory') exists only on main after 45f8de0 and is not in any tagged release as of 2026-10-22. 'Supersedes' therefore applies to main only. Cite v1.2 for the published text and main for the corrected rule. Curator amendment CA-AM-0082 (2026-10-22): Re-read 2026-10-22 at swhid/specification main e1c6c7b4 (HEAD unchanged since 2026-09-19). In Chapters/4.Syntax.md (readback 751b992efbaff75f) the grammar lists path_ctxt among context qualifiers with no object-type restriction ('<path_ctxt> ::= "path" "=" <path_absolute_escaped>'), so applicability is set only in chapter 6. In Chapters/5.Core_identifiers.md (readback 2b4dc726ab2d5bc6), directory entries use four modes (100644, 100755, 120000, 40000), with no gitlink 160000, and each entry carries 'the intrinsic identifier of the content or directory' (line 65). That matches the reasoning of fix 45f8de0: a path can designate only a content or directory. A.Conformance.md (c42259118ee76cc4) and 3.Terms_and_definitions.md (56ef7f517c3b3748) contain no path-qualifier statement. No remaining chapter on main contradicts the corrected 6.3.4 sentence. Released v1.2 (a9fdba9) still carries the old sentence, as recorded in C3R-0516. Limitations: Spec and docs read 2026-10-22; no SWHID computed or resolved. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
