# Phase 25 Plan 01: Loadtest Config Upload Summary

**`cargo pmcp loadtest upload` command with TOML validation, OAuth auth, GraphQL upload, and actionable error/success feedback**

## Performance

- **Duration:** 3 min 24 sec
- **Started:** 2026-02-28T15:21:31Z
- **Completed:** 2026-02-28T15:24:55Z
- **Tasks:** 3
- **Files modified:** 3

## Accomplishments
- Added `upload_loadtest_config()` GraphQL mutation function and `UploadLoadtestConfigResult` response struct to graphql.rs
- Created complete `upload.rs` with read-file, validate-TOML, derive-name, authenticate, upload, and display flow
- Wired `Upload` variant into `LoadtestCommand` enum with CLI arg definitions and match-arm dispatch

## Task Commits

Each task was committed atomically:

1. **Task 1: Add upload_loadtest_config() GraphQL mutation** - `77c6bf3` (feat)
2. **Task 2: Create upload.rs implementation** - `d87002a` (feat)
3. **Task 3: Wire Upload variant into LoadtestCommand enum** - `3c24742` (feat)

## Files Created/Modified
- `cargo-pmcp/src/deployment/targets/pmcp_run/graphql.rs` - Added UploadLoadtestConfigResult struct and upload_loadtest_config() mutation function
- `cargo-pmcp/src/commands/loadtest/upload.rs` - Complete upload flow: validate TOML, authenticate, upload via GraphQL, display success/error
- `cargo-pmcp/src/commands/loadtest/mod.rs` - Added Upload variant to LoadtestCommand enum, mod upload declaration, dispatch match arm

## Decisions Made
- Validate TOML config before authenticating -- fail fast on bad configs without wasting time on OAuth flow
- Config name defaults to filename stem when --name not provided
- Reuse LoadTestConfig::from_toml() for validation -- same validation as loadtest run ensures consistency

## Deviations from Plan

### Auto-fixed Issues

**1. [Rule 1 - Bug] Fixed rustfmt formatting in upload.rs**
- **Found during:** Task 3 (wiring)
- **Issue:** Several eprintln! and println! calls had unnecessary multi-line wrapping that rustfmt wanted collapsed
- **Fix:** Ran cargo fmt to auto-format
- **Files modified:** cargo-pmcp/src/commands/loadtest/upload.rs
- **Verification:** cargo fmt --check passes
- **Committed in:** 3c24742 (Task 3 commit)

---

**Total deviations:** 1 auto-fixed (formatting)
**Impact on plan:** Trivial formatting adjustment. No scope creep.

## Issues Encountered
None

## User Setup Required
None - no external service configuration required.

## Next Phase Readiness
- Upload command compiles and is wired into CLI
- Ready for 25-02 plan (cargo check integration test, help text verification)
- All quality gates pass (clippy zero warnings, fmt clean, cargo check success)
