coverage.anchor¶

Per-capture anchor resolution: one tree diff, per-file blob fallback (spec §8/§9).

Semantics table lives in AnchorResolver’s docstring; keep it in sync with tests/unit/cov/test_anchor.py.

class otto.coverage.anchor.AnchorResult(new_relpath: ~pathlib.Path | None, hunks: list[~otto.coverage.capture.remap.Hunk] = <factory>, verifiable: bool = True)¶

Bases: object

Where one file’s capture coordinates land in the current tree.

new_relpath : Path | None¶

hunks : list[Hunk]¶

verifiable : bool = True¶

class otto.coverage.anchor.AnchorResolver(repo_root: Path, base_commit: str, *, files: dict[str, CaptureFileCov] | None = None)¶

Bases: object

Resolve every file of one capture against the working tree.

situation | result |

base ok, absent from tree diff | (relpath, [], True) — unchanged/ws-only |

base ok, modified | (relpath, hunks, True) |

base ok, renamed | (new_path, hunks, True) |

base ok, deleted | (None, [], False) |

base missing (GC’d / shallow) | batched fallback index (or per-file chain) |

resolve(relpath: Path, fc: CaptureFileCov) → AnchorResult¶

Resolve one capture-relative relpath against this resolver’s diff/fallback.
