v1.79.1

[1.79.1] - 2026-08-18 — Alkaid

Theme: first follow-through on 1.79.0's per-migration transaction — a tolerant schema
operation that predates it learns to stay out of its way. Low risk: schema-internal, no
API/env/config changes.

Fixed

• Tolerant index drops no longer poison the per-migration transaction: dropIndex now emits
  DROP INDEX IF EXISTS on PostgreSQL and SQLite. SchemaBuilder::dropIndex() has always
  swallowed a failed drop, but under 1.79.0's per-migration transaction the errored statement
  aborted the transaction (PostgreSQL 25P02) and failed every later statement — surfaced by
  fresh-chain migrations that defensively drop-then-recreate an index.

Changed

• Release notes no longer reference the host application by name (1.79.0 intro and the 1.68.0
  config-override entry now describe the consuming application generically).

Removed

• The pre-release ledger upgrade path in ensureVersionTable() (retrofitting a source
  column onto sourceless dev-era version tables): every real install's ledger was created
  with the column, and there are no external framework consumers to carry the seam for.
