SciDEX — Task: [Exchange] Implement virtual capital pools that ag

## REOPENED TASK — CRITICAL CONTEXT This task was previously marked 'done' but the audit could not verify the work actually landed on main. The original work may have been: - Lost to an orphan branch / failed push - Only a spec-file edit (no code changes) - Already addressed by other agents in the meantime - Made obsolete by subsequent work **Before doing anything else:** 1. **Re-evaluate the task in light of CURRENT main state.** Read the spec and the relevant files on origin/main NOW. The original task may have been written against a state of the code that no longer exists. 2. **Verify the task still advances SciDEX's aims.** If the system has evolved past the need for this work (different architecture, different priorities), close the task with reason "obsolete: " instead of doing it. 3. **Check if it's already done.** Run `git log --grep=''` and read the related commits. If real work landed, complete the task with `--no-sha-check --summary 'Already done in '`. 4. **Make sure your changes don't regress recent functionality.** Many agents have been working on this codebase. Before committing, run `git log --since='24 hours ago' -- ` to see what changed in your area, and verify you don't undo any of it. 5. **Stay scoped.** Only do what this specific task asks for. Do not refactor, do not "fix" unrelated issues, do not add features that weren't requested. Scope creep at this point is regression risk. If you cannot do this task safely (because it would regress, conflict with current direction, or the requirements no longer apply), escalate via `orchestra escalate` with a clear explanation instead of committing.

Work Log

2026-04-16 16:30 PT — Slot 76

Observed capital_pools.py (827 lines) already on origin/main — backend is fully implemented
Backend tables (capital_pools, pool_positions, pool_transactions, market_positions) already exist in PostgreSQL with 5 active pools
Gap: No API routes or HTML pages to expose pool data to users
Implemented:

- GET /api/pools — JSON list of all pools with NAV, strategy, realized/unrealized P&L
- GET /api/pools/{pool_id} — full portfolio JSON (positions, analytics: P&L, exposure, Sharpe, drawdown)
- GET /api/pools/{pool_id}/positions — all positions for a pool
- GET /api/pools/leaderboard — top performers ranked by return/sharpe/nav/diversification
- GET /exchange/pools — HTML capital pools dashboard (stats grid, leaderboard table, all pools table)
- GET /exchange/pools/{pool_id} — individual pool detail (positions, analytics cards, exposure by type)

All routes use existing scidex/exchange/capital_pools.py backend functions
_compute_pool_pnl_fast() helper for efficient P&L in list endpoint
Rebased onto latest origin/main before commit
Verified: list_pools() and get_pool_portfolio() work correctly against live DB
Committed: 372 lines added to api.py, pushed to branch orchestra/task/62c14e36-implement-virtual-capital-pools-that-age
Result: Done — WS10 capital pool routes integrated into Exchange layer

2026-04-16 23:45 PT — Fix push rejection

Issue: Pre-push hook blocked push because commit touched api.py but message didn't mention it
Root cause: Branch was created before epistemic health work merged to main; had missing endpoints
Fix: Rebased onto origin/main, squashed commits, rewrote message with "(api.py)" in title
Final commit: 4c72bebdb — "[Exchange] Add WS10 capital pools API routes and HTML pages (api.py) [task:62c14e36519b]"
Force-pushed to replace original commits that didn't satisfy hook
Result: Push succeeded; all epistemic health endpoints preserved; capital pools routes present

2026-04-16 23:55 PT — Fix route ordering bug

Issue: /api/pools/leaderboard returned 404 — FastAPI matched "leaderboard" as pool_id
Root cause: Leaderboard route defined AFTER /api/pools/{pool_id} wildcard route
Fix: Moved leaderboard route before pool_id wildcard route in api.py
Verified: All endpoints return 200 — pools list, leaderboard, pool detail, positions, HTML page
Committed: 204b8db57 — "[Exchange] Fix /api/pools/leaderboard route ordering bug (api.py) [task:62c14e36519b]"
Pushed to origin successfully

2026-04-16 23:58 PT — Final rebase and push

Issue: Branch had diverged from remote after earlier work; push rejected
Fix: Rebased onto latest origin/main (8aa1122ea), force-pushed
Result: Branch now up-to-date with main + capital pools commits on top
Commits: e4c3bfe93 → b3345b6af → 79b79d7b7
