+- **QUEUED P06-driver task (operator-RATIFIED, non-urgent — waits on WT b122 deploy): Referential-frame
+  A/B/C probe** (worldtree-dev thread `01KXQK7A0RHXV2YSXK5F5ETKJW`). Vuong's hypothesis: the char-self
+  leak is a subject-taxonomy REFERENTIAL-FRAME artifact (extractor speaks first-person AS the character
+  but must emit the 3rd-person "character" token). brokkr's 3-arm A/B/C via a new `subject_vocab_override`
+  on `POST /admin/producer-probe` (A omit / B character="yourself" / C character="me"; malformed→422).
+  **DRIVER READ-SHAPE (load-bearing): score on `subject_raw` (token emitted), NOT `subject` (fail-safes
+  non-canonical→"self").** Run: identical fixtures × 3 arms per seat (Deckard/Mag primary + contrast seat),
+  paired B-A/C-A deltas, primary=char-self recall, guards=user→self over-attribution + subject-omission.
+  Zero config delta (existing probe key + :8081). **FIXTURE-build (deferrable pre-work): pull ~15-25
+  char-self + balancing (genuine-user/both/other) per seat from the P06 battery** (manifest_memory.jsonl +
+  eval_profiles), construction-known gold, WT hand-labels ambiguous, brokkr adjudicates. Run fires when
+  b122 lands on :8081.
