-summary: >
-  Complete the instrument-aware quote-unit rollout so quoted instruments like GLD are
-  handled explicitly as USD/share and only converted to ounce-equivalent values through
-  named metadata-backed seams.
-acceptance_criteria:
-  - GLD quotes are modeled explicitly as prices per share, not as ambiguous gold-ounce prices.
-  - Instrument metadata encodes that 1 GLD share represents 0.1 troy ounces of gold exposure.
-  - Storage/domain value classes know the unit relationship and convert correctly when calculations combine instrument prices with ounce-based quantities.
-  - Cross-unit operations fail closed when no explicit instrument conversion path exists.
-  - Visible ounce-based pages beyond overview use the explicit conversion seam instead of heuristic fallbacks.
-  - Tests cover GLD share <-> troy-ounce conversion and reject unsupported mixed-unit operations.
-technical_notes:
-  - `CORE-002A` is complete: overview now uses explicit GLD share -> USD/ozt conversion with quote-unit metadata and cache normalization.
-  - `CORE-002B` is complete: hedge/runtime displays now use the explicit converted collateral spot seam and recompute runtime snapshots from that spot.
-  - Remaining suggested slice is `CORE-002C`: historical/workspace collateral conversion alignment for backtests/event-style GLD share defaults.
-  - Prefer explicit instrument/unit types over ad hoc scale factors in page/service code.
-  - This should integrate with the Decimal/unit-safe domain model rather than bypass it with raw floats.
-  - Consider extending historical/unit types so both live overview paths and backtesting/event paths can share the same conversion rules.

-summary: Align workspace-derived collateral defaults with explicit GLD share semantics in historical/backtest-style paths so workspace collateral is converted through named metadata rather than ad hoc share assumptions.
-acceptance_criteria:
-  - Backtest/event-style workspace seeding uses explicit metadata-backed collateral/share conversion rules.
-  - Historical/unit materialization remains compatible while avoiding ambiguous share-vs-ounce assumptions.
-  - Unsupported or missing conversion metadata fails closed.
-  - Tests cover workspace-derived default seeding and changed browser-visible read paths where relevant.
-technical_notes:
-  - Likely file targets include `app/domain/backtesting_math.py`, `app/services/backtesting/ui_service.py`, `app/services/backtesting/comparison.py`, and `app/services/event_comparison_ui.py`.
-  - Reuse the instrument metadata seam introduced in `CORE-002A`/`CORE-002B`.
