Continued with a cleanup consistency slice.

Updated:
- Fixed stale Phase 20 report wording to match current repo state:
  - [samples2tools_phase20_deprecation_note.txt](C:\Users\davidq\Documents\GitHub\HTML-JavaScript-Gaming\docs\dev\reports\samples2tools_phase20_deprecation_note.txt)
  - Renamed/report text now reflects full removal (not “still on disk”).

Added validation/report:
- [samples2tools_batch_47_validation.txt](C:\Users\davidq\Documents\GitHub\HTML-JavaScript-Gaming\docs\dev\reports\samples2tools_batch_47_validation.txt) (`PASS`)
- [samples2tools_batch_47_summary.txt](C:\Users\davidq\Documents\GitHub\HTML-JavaScript-Gaming\docs\dev\reports\samples2tools_batch_47_summary.txt)

Validation confirms:
- Phase-20 samples in metadata: `0`
- Phase-20 phase descriptor: removed
- `samples/phase-20` directory: removed
- Note/report text now matches removal state

Commit comment:
`Reconcile Phase-20 reporting with hard-removal state: update deprecation note to removal wording and add batch-47 PASS validation confirming zero phase-20 metadata entries and no phase-20 directory.`

 Status:
-- Phase 20 remains on disk for compatibility/regression checks.
-- Phase 20 is deprecated as a primary launch surface for Samples2Tools lane.
-- Primary sample discovery now excludes phase 20 in samples/index.render.js.
-- Replacement non-Phase-20 mapping coverage and launch parity are validated in batch 34.
+- Phase 20 artifacts are removed from the repository.
+- Phase 20 metadata entries are removed from samples metadata.
+- Samples2Tools no longer relies on phase-20 exclusion/filter workarounds.
+- Replacement non-Phase-20 mapping coverage and launch parity were validated before removal.
