+## Phase R: unlabelled counted attempts of the seven original agents (2026-11-08)
+
+- Runs: the counted attempt of each of the seven original agents on each test of the eight-agent common set (808 core
+  tests) whose task has a phase-2 DAG, when that attempt had no label under `phase2/`: reruns after 2026-11-06 that
+  replaced a labelled attempt, and attempts newer than the phase-2 run catalog. Renamed realtime runs
+  (`-standard-realtime` -> `-realtime`, same trial) count as labelled and are not repeated.
+- **Writer: Claude Sonnet 5.5 (`claude-sonnet-5-5`, Claude Code)**, as for phase K, by the owner's decision of
+  2026-11-08; the reviewer is Claude Sonnet 5.5 in a separate session. Prompts v3.2, the task's phase-2 DAG as
+  published under `phase2/` (not rewritten), the same task inputs, oracle rule, review rounds and validation. Each file's
+  `provenance` says `engine: claude`, `model: claude-sonnet-5-5` and carries a `writer_note`.
