Rangle Weekly - WK41 Retrospective

Week Context

Dates: Mon 2025-10-06 → Fri 2025-10-10 Sprint: Sprint 14 (continued) Theme: ritualize_your_circuit

Wins Worth Capturing

Issue #368 - Conditional Product Addition (Mon-Wed)

• What: Nuke-driven implementation - full feature in ~2 hours vs 11-14 hour estimate
• Evidence: Branch feat/368-conditional-assessment-products ready Oct 7, E2E tested
• Impact: Admin configures “add to basket” nodes for assessments (needles, sharps bins for weight loss)
• Hyperfocus magic: 1k line PR felt smooth, not overwhelming
• Evening session (Tue): Fixed 3 bugs - text sync, module resolution, HTML preview
• Documentation: Created issue-368-product-architecture-handbook.md, implementation guide, handoff notes

Issue #506 - Assessment Save/Copy Issues (Thu)

• What: Date format change (YYYY-MM-DD → DD-MM-DD) + save bug fix
• Evidence: PR #560 created, 17 minutes total implementation time
• Impact: UK date format, fixed “save and close” error

PR #532 - Unique Assessment Naming (Mon)

• What: Timestamp-based copy names to prevent duplicates
• Evidence: Created Oct 6, merged Oct 9
• Impact: [copy::YYYY-MM-DD HH:MM:SS] format prevents conflicts

Invoice Submission (Mon)

• What: INV-2025-006 (Sept 15-26, 2025)
• Evidence: 72 hours, $8,949.60 submitted to Rangle
• Impact: SQLite tracking system operational

What Shipped

PRs Merged:

• #532 - Unique assessment naming with timestamp-based copies
• #560 - UK date format + save bug fix (Issue #506)
• #529 - Confirmation assessment node (from WK40)

Issues Closed/Advanced:

• #368 - Conditional product addition (implementation complete, ready for review)
• #506 - Assessment save/copy issues (fixed)
• #441 - BMI traffic light (cannot reproduce, working as expected)

Sprint Demo (Thu Oct 10)

What I Demoed:

• Product node configuration for conditional assessment product addition
• Assessment + product flow working end-to-end

Outcome: Demo went well, moved on with rest of day

Scott Sync (Thu Oct 10)

Architecture Change Decision - Issue #368:

• Old flow: Assessment submitted → add-ons auto-added to basket
• New requirement: Assessment submitted → user sees “add to basket” → click adds main product + add-ons together
• Rationale: User may complete assessment but choose not to add product
• Estimate: “A few hours” rework
• Implementation: Deferred product addition until explicit “add to basket” click

Issue #506 Sub-Items:

1. Save and close bug - assessment already saved, shouldn’t error
2. Date format change - DD-MM-YYYY (UK standard) implemented

New Enhancement Identified:

• Product selection type-ahead (like health profile nodes) - created as backlog ticket (not current work)

Patterns Working Well

Nuke-Driven Development:

• Issue #368 started complex (11-14 hour estimate) → reset branch → simplified approach (~2 hours)
• Evidence: Cowboy claude executed “complete rewrite” after initial complexity spiraling
• Why it worked: Fresh start eliminated accumulated decisions, clearer solution emerged

Handbook Creation During Work:

• Created issue-368-product-architecture-handbook.md while implementing
• Prevented architecture re-discovery in next context window
• Pattern: “Figured this is probably good information to keep track of for next context window”

Architecture Investigation Complete Before Implementation:

• Reconnaissance + Cowboy prompt generated before starting (Issue #368)
• Repository architecture mapped: monorepo, assessment flow, database, node types
• Template pattern identified (PR #529 confirmation node as reference)

Needs Adjustment

Architecture Change Mid-Implementation:

• Issue #368 implementation complete → Scott sync revealed new requirements
• Impact: Rework needed (assessment submission vs “add to basket” click timing)
• Pattern: Earlier alignment on user flow would prevent rework
• Experiment: Prototype user flows before full implementation for complex features

Cannot Reproduce Bugs:

• Issue #441 (BMI traffic light) worked on staging, cannot reproduce
• May have been created when defaults weren’t saved
• Experiment: Document “cannot reproduce” pattern, track if recurs

For Next Week (WK42)

Queued Work:

• Issue #368 - Architecture change implementation (deferred product addition)
• Issue #550 - Recommended products regression
• New tickets from Scott: search functionality + assessment handling improvements

Follow-ups:

• Scott discussing with Matthew about assessment UX approach
• PR review feedback if any comes in

Session Characterization: Nuke-driven velocity week - full features in hours not days

Daily Notes: 2025-10-07 through 2025-10-10 Velocity: 1 issue closed, 2 PRs merged, 1 major feature implemented, Sprint demo completed Hyperfocus Pattern: Issue #368 “felt smooth” despite 1k lines - alignment with cognitive energy
