Summary by CodeRabbit
WalkthroughThe change omits zero-sized planned phases, derives materialized phase metadata, supports legacy phase-index gaps, and makes automatic and manual dispatch skip non-terminal empty phases. ChangesEmpty Phase Handling
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🔵 Low · up to REST list pagination can return duplicate or missing operation runs when multiple records share the same creation timestamp, so the change is mergeable with explicit owner awareness and follow-up to add a unique ordering tie-breaker. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

so it sorts by orun.created_at descending and uses orun.id descending as a
unique secondary key; keep the existing Offset and Limit behavior unchanged.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Add a unique secondary sort key before pagination.
Line 190 orders only by orun.created_at. Runs with equal timestamps have an undefined relative order. Offset pagination can then skip or repeat runs. Order by orun.created_at DESC, orun.id DESC before Offset and Limit.
Proposed fix
- OrderExpr("orun.created_at DESC")
+ OrderExpr("orun.created_at DESC, orun.id DESC")As per coding guidelines, “Paginated operations must implement deterministic ordering before pagination”.

Percentage and equal phase planning can round a configured phase down to zero targets when the selected rack set is small. The planner previously preserved that empty phase index, while the dispatcher treated a phase with no targets as unfinished. Runs then stayed Running forever before later targets were submitted.
This change:
totalPhasesfrom the materialized target phase indexes for detail, list, and locked control reads, keeping reported progress on the same coordinate as the dispatcher without adding application-level N+1 queries;Together, these changes let new runs complete with contiguous phase indexes and allow already-persisted runs with sparse indexes to recover.
