stripShippedMilestones() uses a negative heuristic: strip all <details>
blocks, assume what remains is the current milestone. This breaks when
agents accidentally wrap the current milestone in <details> for
collapsibility — all downstream consumers then see an empty milestone.
Observed failure: cmdPhaseComplete() returns is_last_phase: true and
next_phase: null for non-final phases because the current milestone's
phases were stripped along with shipped ones.
Added extractCurrentMilestone(content, cwd) — a positive lookup that:
1. Reads the current milestone version from STATE.md frontmatter
2. Falls back to 🚧 in-progress marker in ROADMAP.md
3. Finds the section heading matching that version
4. Returns only that section's content
5. Falls back to stripShippedMilestones() if version can't be determined
Updated 12 call sites across 6 files to use extractCurrentMilestone:
- core.cjs: getRoadmapPhaseInternal(), getMilestonePhaseFilter()
- phase.cjs: cmdPhaseAdd(), cmdPhaseInsert(), cmdPhaseComplete() (2 sites)
- roadmap.cjs: cmdRoadmapGetPhase(), cmdRoadmapAnalyze()
- commands.cjs: stats/progress display
- verify.cjs: phase verification (2 sites)
- init.cjs: project initialization
Kept stripShippedMilestones() for:
- getMilestoneInfo() — determines the version itself, can't use positive lookup
- replaceInCurrentMilestone() — write operations, conservative boundary
- extractCurrentMilestone() fallback — when no version available
All 755 tests pass.
