gitea_delete_branch accepted explicit org/repo but did not propagate them
through the anti-stomp preflight. During a deletion targeting
Scaled-Tech-Consulting/Gitea-Tools, preflight resolved the remote-wide prgs
default (Scaled-Tech-Consulting/Timesheet) and failed closed with wrong_repo
before any deletion — because verify_preflight_purity was called without
org/repo and the shared #604 anti-stomp resolution fell back to the REMOTES
default.
Fix (delete_branch only; REMOTES untouched):
1. Forward the explicit org/repo into verify_preflight_purity so the shared
#604 anti-stomp resolution validates the *targeted* repository instead of
the remote-wide default. Explicit Scaled-Tech-Consulting/Gitea-Tools now
propagates through role/workspace verification, verify_preflight_purity,
anti-stomp repository resolution, and the final native deletion request.
2. Add a workspace-derived repository-binding gate
(_delete_branch_repository_binding_block) that validates explicit
coordinates against the immutable, workspace-aligned repository identity.
Wrong, substituted, or unverified coordinates fail closed — independent of
the anti-stomp remote/repo guard, which by the #530 contract trusts explicit
caller intent. REMOTES defaults are never consulted as an authorization
scope.
Preserved: reconciler-only ownership of gitea.branch.delete; author/reviewer/
merger denial; protected and preservation/evidence gates; missing coordinates
still fail closed via the anti-stomp default resolution.
Regression matrix (tests/test_issue_733_delete_branch_repo_forwarding.py):
Timesheet-default + explicit Gitea-Tools permits an eligible deletion and
forwards the coordinates; wrong/substituted/unverified coordinates fail closed;
author/reviewer/merger remain denied; protected and preservation branches
remain blocked; anti-stomp resolution marks explicit coordinates authoritative
and fails closed on the remote-wide default for omitted coordinates; the
task-capability and role-routing maps stay consistent.
