Implement automatic and chain-forwarding of Assumptions of Use (AoU) between dependable elements: - Add ForwardedAoUInfo provider carrying own and chain-forwarded AoU lobster entries as depsets - Add aou_lobster field to AssumptionsOfUseInfo for lobster extraction from AoU TRLC sources - Extend dependable_element rule to collect own AoUs from deps, receive chain-forwarded AoUs, and emit ForwardedAoUInfo - Add aou_forwarding attribute accepting a YAML file that selects which received AoUs to forward further (with mandatory justification) - Add aou_forwarding_to_lobster.py tool for filtering received AoUs based on the forwarding YAML (supports versioned lobster tags) - Add lobster_aou.yaml config for lobster-trlc extraction of AoU records - Extend lobster_de.conf.tpl with Forwarded AoUs tier Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
Test the aou_forwarding_to_lobster filter logic: - Filtering by AoU ID from forwarding YAML - Error on non-existent AoU ID - Versioned tag matching (req Pkg.Name@1 matches aou_id Pkg.Name) - Full versioned ID matching Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
Extend the examples with a three-level forwarding chain:
other_seooc (defines TimingConstraint and SpaceConstraint AoUs)
↑ deps
safety_software_seooc_example (chain-forwards TimingConstraint)
↑ deps
integrator_seooc (receives forwarded AoUs, has own requirements)
- Add AoU TRLC sources to other_seooc and wire assumptions_of_use
- Add aou_forwarding.yaml to seooc for chain-forwarding
- Create integrator_seooc with assumed system requirements, feature
requirements, and component requirements

Tool requirements (TRLC): - Add Forward_AoU_To_Dependees use case - Add potential errors: AoU_Silently_Dropped, Invalid_Forwarding_YAML_Accepted - Add tool requirements: Forward_Own_AoUs_To_Dependees, Chain_Forward_Received_AoUs, Reject_Unknown_AoU_In_Forwarding_YAML, Include_Forwarded_AoUs_In_Traceability User documentation: - Extend requirements.md with AoU Forwarding section explaining both automatic and chain-forwarding mechanisms - Add aou_forwarding attribute to dependable_element in rule_reference.rst - Add Forwarded AoUs to the dependable element concept in general.md Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
