Installed Official30 generated sections lack their tracked source dependency #499

General technical defect

An ordinary installed OpenHCS0.8.7 package advertises openhcs_official30_benchmark_recipes generated source sections, but a tracked common example source is not part of the manifest-derived package projection and its default root is cwd-relative. The public selector then correctly returns official30_source_missing instead of the advertised importable source.

This is a nested dependency/availability gap, not a missing declared top-level resource or a malformed section request. Full benchmark native references/results and private scoring material must remain excluded.

Retained original witness (not replayed)

Original public request:

{"document_id":"openhcs_official30_benchmark_recipes","section_id":"cp-tutorial-translocation-start-openhcs-python","max_chars":50000}

Original response: valid selected section, content="", truncated=false, errors[0].code="official30_source_missing". Reported path is the caller's output cwd plus benchmark/reference_exports/official30_value_completion_20260914/cp_tutorial_translocation_start.cppipe.

The distinct final-section call previously timed out with mcp_transport_failed/TimeoutError and remains UNKNOWN. It was not retried, resumed or used to infer conversion completion. That separate timeout belongs to #376.

Source/package evidence

• Frozen ordinary wheel source main: 6ce527a29c421ef5a95217b58e8bc33a93ba5fa2; wheel SHA256 36c6c656a7b257e1da5bc0e6f6c126d3aa8246e9508b5ee89f1cd009f2b4cf33.
• Current main: 72ae6bf2dd3ddc990c282eb2be200dab717cbd05. Relevant package projection, knowledge owner, service and both manifests are unchanged versus frozen main.
• Wheel and installed RECORD contain the knowledge/official30 manifests, but no .cppipe members.
• The original common source is tracked and exists: benchmark/reference_exports/official30_value_completion_20260914/cp_tutorial_translocation_start.cppipe, 7925bytes, SHA256 15d95afa1821526e5b58cc76fc33916ee0107ba5a3123cba33fa91ac319e5708. Contents/settings were not inspected in this triage.
• Its official30 declaration uses cppipe_path_root=reference_export_pipelines, whose default is relative and whose explicit environment contract is OPENHCS_REFERENCE_EXPORT_PIPELINES_ROOT.
• _comparison_manifest_root_path returns the relative default; _official30_source_section_lines resolves it at current cwd.
• declared_knowledge_source_paths projects the top-level knowledge manifest/documents only, not this nested source dependency. Therefore declared-resource byte qualification can PASS while generated sections are unavailable.
• Packaged skill/example map instruct agents to select generated sections as first-choice sources; the ordinary package does not supply this tracked dependency.

Ownership/overlap

Original owners: KnowledgeBaseService generated selection, _ComparisonManifestPathResolver portable roots, knowledge_manifest installed resource roots, and BuildPyWithMcpKnowledge/SdistWithMcpKnowledge -> project_knowledge_assets package projection. No alternate importer/registry/fallback proposed.

#376/merged #377 addresses conversion discovery/deadline, not this source availability. #377 is already present in the frozen ancestry. Current open PRs and missing-source/knowledge-package issue searches found no matching availability fix. This receipt is the packaging triage owner's separate technical report; no scientific workflow intervention.

Later acceptance (not run)

Use the ordinary installed public knowledge entrypoint outside a checkout cwd, the existing source/package declaration owner and canonical importer. A declared common generated-source section must resolve its owned dependency without a parallel registry, checked-in generated Python copy, downloading the benchmark, or including private native/reference/result trees. Preserve typed missing-source errors and the original10second observation boundary. Installed selection/conversion evidence is required separately from source/package membership.

No imports, tests, builds, native/UI/provider calls, downloads or source edits were performed. Original UNKNOWN and frozen scientific evidence remain unchanged.
