🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Make invalid predecessor index data fall back to fresh analysis.
A syntactically valid index can contain {"entries": {"key": null}}. lookup_predecessor() then calls entry.get(...) and raises instead of returning a predecessor miss. Invalid UTF-8 also raises UnicodeDecodeError because load() does not catch it.
Validate each loaded entry before retaining it. Catch decode errors and return an empty index. Add tests for non-dict entries and invalid UTF-8 input.
Per CONTRIBUTING.md: “Validate the new persistence and reuse logic with focused tests, including corrupt, missing, incompatible, and invalid predecessor data.”

Enforce a canonical workdir boundary before rebasing evidence.
startswith(old_prefix) accepts sibling and traversal paths. For example, /old/workdir-other/log:1 is rebased although it is outside /old/workdir. A value such as /old/workdir/../other/log:1 also preserves traversal in the new evidence path.
Canonicalize both paths and require the evidence path to be relative to the canonical predecessor workdir before constructing the new path. Add negative tests for sibling-prefix and ../ paths.

Reset rca_output before the fresh-analysis path.
When the reuse path validates the predecessor output but the write fails, the code sets reused = False and leaves rca_output pointing at the rebased predecessor output (Lines 1052 and 1071). The fresh analysis then runs. If final_text is empty (Line 1147), rca_output keeps the predecessor value. The code then builds an index entry at Line 1157 with predecessor RCA content, even though this run produced no output and returns saved = False. A successor run can reuse that entry for the same key.
Clear rca_output at the start of the fresh-analysis block so only fresh output can populate the index entry.

+ # Discard any predecessor output that failed to persist so the
+ # index entry reflects only this run's fresh analysis.

Remove the hardcoded temporary-path literals or suppress S108 with justification.
Ruff reports S108 for these /tmp/... values. This prevents the required clean Ruff result. Use test-local temporary directories where paths must exist. Use non-temporary placeholder paths where parsing only requires a string.

Validate loaded entries and catch decode errors.
load_index copies entries without checking each value. An index file containing {"version": 2, "entries": {"k": null}} passes this code. lookup_predecessor then calls entry.get("analyzer_fingerprint") on None and raises AttributeError inside the worker thread, which the pipeline reports as a failed job instead of a predecessor miss.
path.read_text() also raises UnicodeDecodeError for invalid UTF-8. UnicodeDecodeError derives from ValueError, so the except (json.JSONDecodeError, OSError) clause on Line 87 does not catch it.
Keep only dict entries and catch the decode error, so invalid predecessor data falls back to fresh analysis.
