v0.5.0 — board-commissioning standards

Field reports from an agent-run project-board commissioning, adopted into the standard (ADR-0008, PR #24, issues #21–#23):

Added

• Links section in doc-style.md (#22): code formatting means "paste this", a link means "go here" — scope explicitly includes the agent's own chat output, with a construction table for the chat and cross-repo cases where #NN and relative links silently fail. Referenced from agent-collaboration.md, enforced by a new links-resolve pre-PR item, and named in the scaffolded AGENTS.md.
• Commissioning handoff rule in agent-collaboration.md (#21): when an agent commissions shared infrastructure, one assigned, checkboxed issue in the review column owns the manual residue — each step naming why it is manual — instead of end-of-session chat prose. Matching session-end tripwire; the org-migration board-rebuild checklist routes views/auto-add click-through to the handoff issue.

Fixed

• org-migration-checklist.md status-options landmine corrected (#23): a Project's status options can be edited via API without breaking the built-in workflows by echoing existing option ids (ProjectV2SingleSelectFieldOptionInput.id, verified against the live schema); only a full id-less replacement dangles workflows and item values.
