Bug Report: parametrize-base-branch

No bugs found. The change is a simple string substitution (hardcoded "main" → f"{base}...HEAD") with a 4-line helper. The bad-revision, missing-worktree, and empty-file_scope paths are unchanged from v1. All 13 tests pass.

O1 — Base branch not validated against repo at create time

An operator can set base_branch: "typo" in loop.json and the drift gate will fail with a git diff error (warning skip), silently disabling the drift gate. No validation at --create-loop time.

Not a bug — SPEC O3 accepts this: "Wrong base_branch is admin error, not a drift event." Future: --validate-loop.

Verdict

PASS — no blockers.
