# Phase 36 Plan 01: Registry Descriptor & License Fix Summary

**CE description.yml with self-contained native DDL hello_world, LICENSE fixed from BSD-3-Clause to MIT, Cargo.toml bumped to 0.5.4**

## Performance

- **Duration:** 4 min
- **Started:** 2026-03-27T10:26:35Z
- **Completed:** 2026-03-27T10:30:37Z
- **Tasks:** 2
- **Files modified:** 3

## Accomplishments
- Created description.yml with all CE-required fields following rusty_quack canonical format
- hello_world uses fully self-contained native DDL: CREATE TABLE + INSERT + CREATE SEMANTIC VIEW + query
- Resolved license mismatch: replaced BSD-3-Clause LICENSE with MIT (matching Cargo.toml)
- Bumped Cargo.toml version from 0.5.0 to 0.5.4 for milestone close

## Task Commits

Each task was committed atomically:

1. **Task 1: Create description.yml and fix LICENSE mismatch** - `dbfd546` (feat)
2. **Task 2: Bump Cargo.toml version to 0.5.4** - `af0757f` (chore)

## Files Created/Modified
- `description.yml` - CE registry descriptor with extension metadata, excluded platforms, hello_world, extended description
- `LICENSE` - Replaced BSD-3-Clause with MIT license text (Copyright (c) 2026, Paul Garner)
- `Cargo.toml` - Version field updated from 0.5.0 to 0.5.4

## Decisions Made
- **Excluded platforms union:** Combined Build.yml `exclude_archs` (7 platforms) with D-04 list to produce 8 excluded platforms: `wasm_mvp;wasm_eh;wasm_threads;windows_amd64_rtools;windows_amd64_mingw;linux_amd64_musl;linux_arm64_musl;windows_arm64`
- **License resolution:** MIT is canonical (per Cargo.toml and planning notes). Replaced BSD-3-Clause LICENSE file content with MIT.
- **Placeholder ref:** Set `ref: PLACEHOLDER_COMMIT_SHA` per D-06 -- will be replaced with actual main SHA after squash-merge during /gsd:complete-milestone

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered

None.

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness
- description.yml ready for CE submission (after ref SHA replacement post-squash-merge)
- LICENSE and Cargo.toml aligned for registry publication
- Plans 36-02 (MAINTAINER.md updates) and 36-03 (Python example) can proceed independently

## Self-Check: PASSED

- description.yml: FOUND
- LICENSE: FOUND
- Cargo.toml: FOUND
- 36-01-SUMMARY.md: FOUND
