Flaky test ledger

The daily flaky-fix pass reads this file. Append one line per flaky event under Open. The fix pass moves an entry to Fixed with its PR, or to Won't fix with a reason.

Line format: - <date> | <case or test file> | <tier: paid/free/evaluator> | PR #<n> @ <head12> | failed <run id> | rerun passed <run id or "measured N/10"> | <symptom>

Sources: the gate runs' flake-records artifacts (every case the in-run rerun turned green) and the free suites' retried cases. Never a case that failed twice (that is a real failure), never a harness, infra or incomplete red.

A fix changes the cause: a forced probe or a regression that is red on BASE and green with the fix. Weakened assertions, raised thresholds, added trials or samples, changed case kinds, skipped cases and longer timeouts are not fixes.

Last fix pass: <thread> (<date>); see reports/<thread>.md. New entries go at the top, worst (most repeated) first.
