Session config | Load prompts and cases from a local file

[BrianGenisio]

Summary

Prompts and test cases no longer ship hardcoded in the client. The UI loads session.config.json through GET /api/session-config and starts empty when that file is missing.

defaults is optional and only tightens the existing 1–5 run/case limits. initialSession holds promptA, promptB, and cases. A non-empty promptB opens compare mode on load.

This file is not .env. Provider keys stay there. The example is checked in; the real config is gitignored.

Changes

The piece to look at closely is lib/session-config.js. It is browser-safe (no Node imports) so the client reuses the same normalizer the API uses. Invalid or inverted min/max pairs fall back to 1–5 so the UI cannot offer values the eval routes will reject.

session.config.json is gitignored on purpose. Only session.config.example.json should land in the repo.

Test plan

• Start without session.config.json and confirm prompts/cases are empty and runs still say 1–5
• cp session.config.example.json session.config.json, reload, and confirm the capital-city demo plus compare mode
• Change defaults.maxRuns to 3, reload, and confirm the runs label and input max update
• npm test

📝 Walkthrough

Walkthrough

The application now supports local session configuration through session.config.json. A shared normalizer validates run and case limits, prompts, and cases. The server exposes normalized settings through GET /api/session-config. The client loads these settings during startup and applies limits, labels, prompts, and cases. Setup documentation, an example configuration, ignore rules, and automated tests were added.

Merge Risk: ⚪ Minimal · up to e5a67

The PR moves prompts and cases into an optional local session configuration file and preserves empty 1–5 defaults when the file is absent; no actionable merge-blocking risk remains after normal checks and review.

Test the complete normalized defaults payload.

The fixture at Line [80] sets only minRuns and maxRuns. Add custom minCases and maxCases values, then assert both response fields. This verifies that server.js preserves all normalized default bounds.

Inline comments:
In `@lib/session-config.js`:
- Line 112: Update the cases initialization in the session configuration flow to
limit the normalized result from normalizeCases(sessionSrc.cases) to
caseBounds.max, so configured initial cases never exceed maxCases. Add a test
covering more valid cases than the configured maximum and verify only the
allowed number is returned.
