[openfactory-core] A card's pull request is recorded in the tracker's namespace, not the forge's: a project whose name differs from its repository previews nothing

## Observed symptom A card's pull request is recorded in the tracker's namespace, not the forge's: a project whose name differs from its repository previews nothing `Ticket.repo` is read as the repository a card's pull request lives in. It is not: it is where the **tracker** keeps the card. On a GitHub tracker the two coincide (an issue lives in a repository), which is why nothing showed. On every other row they are different levels: The repository the job opened its pull request in is the one its forge was built for: `repo_of(<the C-18 view of the project>)` — the job never passes `repo=` to `open_pr` (`orchestrator/machine.py:1391`). ## Environment GitHub Open-Factory-Digital/openfactory-core #403 ## Trigger / context Public GitHub report in Open-Factory-Digital/openfactory-core (FRESH_7D). ## Source evidence - https://github.com/Open-Factory-Digital/openfactory-core/issues/403 (2026-09-30T22:35:56Z) — evidence_class: PRIMARY_ISSUE_REPORT — #403 ## Freshness - classification: FRESH_7D - retrieved_at: 2026-10-02T10:42:44.319212Z - scout_id: Cb3eb1ad640 ## Scout notes This Problem was published by the KFA Fresh Friction Scout from public sources.
