What shipped today

Today was about quality assurance: running /scout to find bugs left by the overnight pipeline, fixing them, and doing a full end-to-end visual review of the learner flow in the browser.

The scout pass turned up five issues. Four were bugs introduced by the 19-PR overnight pipeline run — duplicate migration timestamps that would break schema application, two .single() calls that crash when rows are missing (dashboard and app layout), and a silent data loss bug where AI scoring could succeed but the persistence write could fail without surfacing the error. The fifth (GH-172, passing lesson context to simulations) was a future enhancement punted to the next milestone.

The first grind attempt with parallel worktree agents hit a cross-contamination problem: stage_all=true caused agents to pick up each other’s changes. One clean PR (GH-168, migrations) merged; the other three were contaminated and closed. The remaining four fixes (GH-148 breadcrumbs, GH-169/170 .single() crashes, GH-171 score persistence) shipped as a single manual PR (#177) and merged cleanly.

The visual review confirmed the full learner flow works end-to-end: login, dashboard with stats cards and simulation personas, modules list with progress bars, module detail with breadcrumbs and goals, lesson pages with typed content units (Concept/Task) and markdown rendering, assessment submission with response persistence, mark-complete with progress tracking, and prev/next lesson navigation. During testing, we discovered six database migrations hadn’t been applied to the hosted Supabase instance — applied them all, which unblocked assessment response saving.

Completed

• GH-148 — Add breadcrumb navigation to learner module detail page
• GH-168 — Fix duplicate migration timestamps causing schema conflicts
• GH-169 — Fix dashboard crash when user has no scored simulations
• GH-170 — Fix app layout crash when user has no membership or profile
• GH-171 — Return error when assessment score persistence fails
• Applied 8 missing migrations to hosted Supabase (assessment_responses table, scoring columns, lesson content units, assessments)
• Full E2E visual review of learner flow (dashboard → modules → lesson → assessment → progress tracking)

Carry-over

• GH-172 — Pass lesson context through to simulation practice (future milestone, not urgent)
• ANTHROPIC_API_KEY not set in .env.local — AI scoring gracefully degrades but won’t produce actual feedback until configured
• Anonymous auth disabled on hosted Supabase — demo flow (/demo) won’t work until enabled in Supabase dashboard
• Paul’s DISC assessment not completed — content shows default style, not DISC-adapted

Risks

• Six migrations were applied directly to production via psql, bypassing Supabase’s migration tracking — if supabase db push is run later, it may try to re-apply them (they use IF NOT EXISTS and ON CONFLICT guards, so should be idempotent)
• Duplicate RLS policies on lesson_progresses — created three then removed them, but the originals were already present; verify no policy conflicts

Flags and watch-outs

• Grind parallel agents with stage_all=true cause cross-contamination in worktrees — need to fix the grind skill to use explicit file staging instead
• Hosted Supabase signup requires email confirmation — can’t create test accounts easily; had to temporarily modify Paul’s password via direct DB access for testing (restored afterward)
• The “Mark complete” button had a transient error on first click (lesson_progresses 403) but worked on page reload — RLS policies were already present, likely a timing/caching issue

Next session

• Set ANTHROPIC_API_KEY in web/.env.local to enable AI scoring feedback on assessments
• Enable anonymous auth in Supabase dashboard if demo flow is needed
• Complete DISC assessment as Paul to see DISC-adapted content in action
• Close “Adaptive lesson delivery” and “First module: Delegation” milestones — all issues are resolved except GH-172 which belongs to a future milestone
• Plan the next milestone — likely “Learner analytics and reporting” or “Multi-module curriculum”
• Consider creating a proper migration tracking solution (run supabase db push or reconcile the manually-applied migrations)
