Project management¶
Day-to-day tracking lives in GitHub Projects (Projects v2), because the
component repos already live under the PacketFive GitHub organisation, so Epics
and Tasks link directly to issues, pull requests, and commits.
- Epics map to the six workstreams above (label
epic). - Tasks map to individual table rows (label
task), linked to their Epic and to the owning component repo. - Status field mirrors the legend (Available / In Progress / Planned / Blocked).
The board is seeded and kept in sync from a machine-readable source of truth:
scripts/roadmap/roadmap.csv, every Epic and Task with status, milestone, and repo.scripts/roadmap/seed_github_project.sh, creates the Project, labels, and issues via theghCLI.
Seeding the board¶
# One-time auth with project scope
gh auth login
gh auth refresh -s project,read:project
# Preview what would be created
scripts/roadmap/seed_github_project.sh --owner PacketFive --dry-run
# Create the board + issues
scripts/roadmap/seed_github_project.sh --owner PacketFive --title "HiCAIN Roadmap"
Keeping this roadmap current¶
- Update
scripts/roadmap/roadmap.csvwhen a task changes status. - Re-run
scripts/roadmap/seed_github_project.sh --syncto reflect changes on the board. - Component versions on this page and in the datasheets update automatically from git tags at documentation build time (no manual edit needed).
