## Thinking Path
Trusted workflow-dispatch runs execute an authorized target SHA, but
GitHub context still describes the default-branch workflow revision.
Retained paid results and artifact names were therefore labeling
target-branch executions as master. The workflow must explicitly pass
its authorized target coordinates to target code and trusted reporting.
## What Changed
- emit the canonical authorized target ref alongside the immutable
target SHA
- pass those coordinates to paid cells and the trusted report
- name shared build/provider artifacts with the target SHA rather than
workflow SHA
- add workflow-security coverage for all trusted provenance wiring
## Verification
- focused workflow-security tests: 6/6 passed
- Prettier and git diff checks passed
- run 33823252706 independently proved the pre-fix defect: functionally
green target cells were retained as master SHA 0ad180b85 instead of
feature SHA 33c7646d3
## Risks
The execution checkout and secret boundary were already pinned
correctly; this changes retained attribution and artifact labels only.
Target-side report code on PR #12769 consumes these trusted environment
values and overwrites untrusted cell metadata.
