📝 Full Task Prompt

## Objective
Correct the weighted sprint progress calculator so stale merge metadata cannot advance tasks that are still in the canonical coding stage.

## Scope
- `src/domain/sprint/sprint-progress.ts`
- `tests/backend/domain/sprint/sprint-progress.test.ts`

## Requirements
1. Normalize task status before evaluating merge state.
2. Treat `pending`/`PENDING` as 0% regardless of stale `isMerged`, merge-indicator, or telemetry values.
3. Treat `in_progress`/`RUNNING` as unfinished coding and calculate only clamped task-coding tool-call progress, ignoring stale `isMerged` and merge indicators.
4. Preserve the existing `coding_completed`, post-coding gate, settled merge-indicator, and completed-task behavior.
5. Add regression tests covering pending and running tasks with stale `CI` and merged metadata, including partial tool-call progress for running tasks.
6. Do not modify lifecycle transitions, database schema, or repository aggregation behavior.

## Verification
- Run `pnpm exec vitest run tests/backend/domain/sprint/sprint-progress.test.ts tests/backend/repositories/project-management-repository.test.ts`.
- Run `pnpm run typecheck`.
- Run `pnpm run typecheck:dashboard`.
