Cross-Language Deletion Ledger

Canonical record of removed package roots from the HoloScript monorepo. Authority: This file. Updates: Append-only; never rewrite history rows. New dispositions go at the bottom. Verification: See research/2026-05-12_deleted-package-disposition-audit.md § Appendix.

Legend

Disposition	Meaning
retired	Intentionally removed; no direct replacement. Capability may exist elsewhere in ecosystem.
merged	Absorbed into another in-repo package. Functionality preserved under new owner.
migrated	Moved to another repository (primarily Hololand platform repo).
superseded	Replaced by a newer or better-scoped package. Old API no longer valid.
unfinished	Incomplete or abandoned; removed to reduce surface area.
bad-idea	Deliberately discarded design. Not coming back.
revive-candidate	Viable to bring back if demand surfaces; no current replacement.

Verification Note

The canonical count of 52 removed package roots was derived by:

1. Computing all directories ever present under packages/ from git add history.
2. Subtracting directories still present in HEAD.
3. Excluding two artifacts: packages/.bench-logs and packages/README.md.

A prior canary estimated 49; the 3 additional roots are packages/demo-apps, packages/intelligence, and packages/unity-adapter, which the canary filter omitted due to heuristic differences (zero package.json at time of deletion, or misclassified as sub-roots).

Expanded repo-wide audit: research/2026-05-12_repo-wide-deletion-disposition-audit.md covers all 5,415 deleted files (not just package roots) and classifies them by the broader taxonomy: cleanup, collateral, merged, migrated, superseded, ghost, shim, retired, unfinished, bad-idea.
