Sprint 06
Table of Contents
This page documents a sprint (Sprint 06) of ORE Studio v0. It captures the sprint's mission, current status, and the stories that compose it. For the surrounding context — version goals, sprint order, and product identity — see Version 0.
Mission
Finish domain-entity follow-ups (session cancellation, feature-flag service); make the comms substrate production-ready; tidy bootstrap and logging surfaces.
(The v0 mission had a second clause — templatise domain entity
generation — that did not land. The Experiment with simple code
generation entry was CANCELLED. Templatised generation reappears in
later sprints with the codegen-driven approach.)

Achievements

- Comms substrate has handshake/protocol split and retry.
- Logging migrated to
std::string_view(with the inevitable post-migration cleanup). - Two predecessor links from sprint 05 closed.

Charts
Charts generated via sprint_charts cmake target.
PRs & Commits per Day
Dual-axis bar chart. PRs (left axis) and commits (right axis) per day. A high commits-to-PR ratio may indicate scope creep.
Daily Line Churn
Lines added (green) and deleted (red) per day. Building work produces mostly additions; refactoring produces a mix. Days with no churn may indicate blockers.
Cumulative Stories Done
Line chart tracking stories marked DONE during the sprint. Steady upward slope is healthy; plateauing signals a stall.
Retrospective
- What worked
- Boost.Asio session cancellation — initially planned as a tidy hierarchical-signal solution, broken by the one-slot-per- signal limitation, recovered via explicit session-list management. The pivot caught in flight pattern is the right way to handle upstream surprises. Two cross-sprint successors closed cleanly.
- What did not
- the second mission clause (templatise domain entity generation) didn't land. The codegen experiment was CANCELLED, and templatisation reappears later with the v2 codegen approach. Worth being more conservative about second mission clauses in future sprints.
- Carry forward to v2
- the LISTEN/NOTIFY thread started here but the full client fan-out is incomplete; expect a successor story in a later sprint when the event bus gets its second consumer.
