# Pending Improvements — HISTORICAL (Bundles A–F closed)

STATUS: This file tracked the original improvement bundles A–F. All are now
DONE or SKIPPED. It is kept (not deleted) because ~45 note stubs and several
doc/test files cite specific items by number (e.g. "item #11", "Bundle C3,
DONE"). Those citations resolve here.

The closed bundles covered correctness, schema, and indexing fixes that
landed in the live DB and validators. The active improvement tracking now
lives in the sibling survey files, each with a distinct scope:

  - sqlite_improvs.txt   — SQLite-layer improvements (built on A–F)
  - duckdb_improvs.txt   — DuckDB engine surface (built on A–F + G–J)
  - graph_improvs.txt    — graph algorithm coverage (G–J; candidates, not
                           committed work)
  - findata_corpus_audit.txt — markdown ↔ SQLite ↔ DuckDB ↔ graph coverage
  - hierarchy_design_roadmap.txt — forward-looking sector-hierarchy design

If you arrived here from a "Bundle Xn" or "item #n" citation, that item is
closed; see the relevant sibling file above for the current state of that
area, or git log for the change.

(Do not re-open this file for new work — add new improvement tracking to the
appropriate sibling file above.)
