📖About

The leo-chat page drifted from its backend (surfaced now that Ninad can finally reach the chat): the frontend fetches /api/conversations/{id}/history?limit=&before= for message pagination, but the backend only has /api/conversations/{id}/messages (no /history, no pagination) so it 404s; and the frontend opens the SSE status stream at an absolute /api/events instead of the app-prefixed API+/api/events, so that 404s too. Both are handled gracefully (the chat still sends/replies), but they spam the console, break older-message pagination, and kill the working indicator. FIX: (1) add GET /api/conversations/{id}/history returning {messages:[{id,role,content,created_at}], has_more} with limit + before pagination matching the frontend contract; (2) fix the frontend EventSource to use the API prefix. Regression test + cookbook.

⚖️Decisions

• Elrond's bypass methodology checklist (a reminder, not a gate -- you've got this): 0. File it requested_mode='bypass' (planner-vs-bypass is a deliberate choice). bypass_start REFUSES a non-bypass initiative (CAROL-INI-1846), and the dispatcher only skips the bypass lane when the mode says bypass -- a 'planner' mistag lets Merlin's pipeline grab the placeholder step and block your finished work. 1. Filed as planned status -- let the bypass claim/activate it; never file active. 2. Open the bypass (bypass_start) with your droid id + the remediation answer (remediates_initiative_id=NNN, or remediates_nothing=True). 3. Work the blocks for your work-type: template -> design -> code -> test -> review. Do the real work; record decisions on the initiative as you make them. 4. Reality is recorded for you at close -- code (files changed), each decision, and the twin-review verdict become real activities tied to this initiative and show in the Activity Tracker like a planner run (CAROL-INI-1840). No dummy rows. 5. Keep the initiative status moving; it parks in 'reviewing' and is tagged uat-pending for you at close (CAROL-INI-1836), so the stuck-watchdog leaves it alone until UAT. 6. Close runs the gates (design/architecture compliance + caller-audit). If a gate flags something pre-existing or unrelated to your change, waive it with a clear written rationale -- audit, don't skip. 7. Bypass skips the planner's auto-orchestration, NOT the standards. Same template checklist, same review, same observability as a planner run. (elrond)
• [status-router] planned -> executing | event=bypass_executing | bypass transition (or-bx-01)
• leo-chat frontend/backend drift (surfaced once Ninad could reach the chat): the page fetched /api/conversations/{id}/history for pagination but the backend only had /messages (404), and it opened the SSE at absolute /api/events instead of the prefixed API+/api/events (404). Both were graceful (chat still worked) but spammed the console and broke older-message pagination + the working indicator. Fix: added GET /history returning {messages:[{id,role,content,created_at}], has_more} with limit+before; frontend events stream now uses the API prefix. test_ini3105 9/9. — Reconcile the frontend contract with the backend so the chat is clean end-to-end.

✅Success criteria

• GET /api/conversations/{id}/history returns {messages, has_more} with limit and before pagination (must_have)
• Each returned message includes id, role, content so the frontend can paginate by id (must_have)
• The frontend EventSource opens the events stream at the API-prefixed path (no root 404) (must_have)
• A regression test proves the /history route returns the expected shape and paginates by before (must_have)
