Backend endpoint verification

Nithilan-posted Perp Pairing — Live Local Endpoint Report

POST /share exercised on the PR branch against the exact @iseayou HYPE lifecycle Nithilan posted in #project-position-detail-view. The local adapter maps cluster-internal user routes to authenticated production routes. The unavailable local Eppo kill switch was pinned to its deployed default (false) only in the ignored build artifact; source and upstream responses were not mocked.

Verification

PASS Exact position ID request succeeds

POST /share returned 201 for the real closed HYPE lifecycle with its stable positionId.

PASS Legacy request succeeds

POST /share returned 201 for the same lifecycle without positionId.

PASS High-activity account history resolves

The market-filtered production history contains 77 HYPE fills and completed inside the new 4-second trade-history budget.

PASS Backend chart generated

Both paths replaced the 2-point client fallback with 40 backend candle points.

PASS Markers generated

Both responses generated open index 9 and close index 39 within the 40-point series.

PASS Position ID stored only when supplied

The exact response persisted the canonical positionId; the compatibility response omitted it.

PASS Posted position identified

Market, dates, size, entry, exit, and PnL match Nithilan's Slack screenshots; the profile is @iseayou, not Nithilan.

What the share-card graph could look like

Profitable lifecycleExit $44.733 is above entry $41.07, so the positive PnL is consistent.
Down from the local peakThe line falls near the end because HYPE peaked at $46.537 before the close. “Down lately” does not mean “down since entry.”
Correct marker windowOpen is index 9 and close is index 39. The first nine points intentionally show price context before entry.
