Cycle-close tidy for broker-foundation (InstrumentSpec deploy metadata #113 + PositionEvent schema #114). Architect drift review (3638d48..HEAD): code is drift-clean. PositionEvent matches the C10 column spec field-for-field (no open_ts, unsigned volume, direction-is-action, bare-i64 action); the engine run-loop is untouched (C14); InstrumentSpec stays Copy metadata at the ingestion edge (C7/C15); no instrument identity reaches the hot path. The only drift was stale ledger prose, fixed here: - C10 realization note: added a cycle-0063 entry recording that the position-event *schema* landed (PositionAction/PositionEvent), while derivation (#115) and the realistic broker nodes (#116) remain the deferred decoupled layer. - C15 realization note: replaced "minimal today (pip only)" with the six-field deploy-grade floor and the #124 currency-type forward note (quote_currency is &'static str; the #124 resolver chooses how its runtime tier carries currency). Regression (verbatim): cargo test --workspace = 458 passed / 0 failed (exit 0); cargo clippy --workspace --all-targets -- -D warnings = clean (exit 0). Carry-on (not actioned, justified): the inline reversal test is a shape-pin only — the behaviour test arrives with #115's derive, and the E2E twin already exercises the reversal wire shape. The quote_currency &'static str / #124 resolver concern is logged on #124 as a deliberate deferred design choice. This is drift-clean, NOT a milestone close — the realistic-broker milestone needs its end-to-end fieldtest green, which depends on #115/#116/#120-123 still to land. Removed the ephemeral cycle artifacts (spec + plan) per the lifecycle convention.
