Persist the two new artifacts beside the existing equity/exposure taps under runs/traces/<name>/:

  • currency_equity — a normal ColumnarTrace tap (single f64 column), drops into the existing persist_traces path (main.rs:171-185).
  • the position-event table — needs a dup-ts-safe format. A plain ColumnarTrace does NOT work: a reversal puts two rows at one event_ts, and any downstream join_on_ts (report.rs:168) collapses duplicate timestamps last-write-wins, silently losing the Close. Either a dedicated table artifact (its own JSON schema + store path) or an explicit within-instant ordinal column that disambiguates co-timestamped rows. Pick the minimal faithful option; pin the reversal round-trip in a test.

depends on: PositionEvent schema (I2), RealisticBroker (I4)
context: C22 — "Displayable = exactly what a sink recorded"; the table must be a durable artifact to be observable and to serve deploy reconciliation. The dup-ts collapse is the specific hazard for this table.

Persist the two new artifacts beside the existing `equity`/`exposure` taps under `runs/traces/<name>/`: - **`currency_equity`** — a normal `ColumnarTrace` tap (single f64 column), drops into the existing `persist_traces` path (main.rs:171-185). - **the position-event table** — needs a **dup-ts-safe** format.

Superseded by the 2026-06-28 C10 rework (ledger commit 29cdc8c): the realistic-broker / currency model is retired (real friction is not historically knowable). Cost in research is now a composable cost-model graph in R (the net-R curve); money / a real broker move to a separate live/deploy edge. See #116 (summary), #148 (cost-model graph), #149 (live/deploy edge). Closing as superseded.
