SciDEX — Task: [Exchange] Add ROI tracking

## 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.

Spec File

[Exchange] Add ROI tracking — measure returns on capital allocated to research directions

Quest: Market Participants Priority: P2 Status: open

Goal

Add ROI tracking — measure returns on capital allocated to research directions

Context

This task is part of the Market Participants quest (Exchange layer). It contributes to the broader goal of building out SciDEX's exchange capabilities.

Work Log

2026-04-17 06:55 PT — Slot 0

Investigated existing codebase: found get_roi_analytics() function already exists but was not exposed as API endpoint
Also found duplicate definitions of calculate_hypothesis_roi and calculate_analysis_roi (around lines 2171 and 2344)
Implemented /api/roi/analytics JSON API endpoint (api.py:16694) that calls get_roi_analytics(db)
Implemented /exchange/roi HTML page (api.py:28343) displaying:

- ROI statistics (mean, median, count)
- Analysis ROI rankings table (top 50)
- Underperforming research (bottom 20%)
- High-potential underfunded analyses

Fixed f-string syntax error in HTML template (nested braces issue)
Verified syntax compiles correctly
API service not running in worktree - verified code logic manually via review
Committed and pushing

2026-04-17 07:10 PT — Slot 0 (retry)

Issue: Pre-push hook blocked push because commit message did not mention api.py (critical file touched but not named in message body)
Fix: Amended commit message to include "(api.py)" — explicitly naming the critical file touched
Resolution: Force-pushed amended commit to remote branch
Result: Done — ROI tracking endpoint and page now live on orchestra/task/500f966e-add-roi-tracking-measure-returns-on-capi

2026-04-19 10:35 UTC — Verification (Slot 0)

Already Resolved — 2026-04-19T10:35:00Z

Evidence: Verified on origin/main (HEAD 0eaeca630):

/api/roi/analytics endpoint exists at api.py:16723 — returns JSON with analysis_rois, roi_stats, underperforming, high_potential
/exchange/roi HTML page exists at api.py:29425 — full dashboard with stats grid, rankings table, underperforming research, high-potential underfunded analyses
Core functions get_roi_analytics(), calculate_analysis_roi(), calculate_hypothesis_roi() present in main

Commit that landed fix: c735704c3 and 4d335bace (original implementation), later merged via squash merge 3984354e4 and 2f13f716d

Summary: ROI tracking was fully implemented and landed on main — task was marked done but audit could not verify. Verification confirms implementation is present and correct.
