Tom Boucher 3599cb0c3e perf(#306): build learnings dedupe index once per bulk import (#386)
learningsCopyFromProject called learningsWrite K times in one process,
and each call re-scanned the entire learnings store to dedupe — O(K*N).
Build the content_hash -> id index once at the start of the bulk import
and thread it through; single-write behavior and the return contract are
unchanged (no caller reads `id` on the created:false branch). O(K*N) ->
O(N+K). Adds a regression test asserting store scan count is independent
of import size.

The larger persistent on-disk index (atomic updates, corruption rebuild,
cross-process dedupe) is deferred — needs design decisions and is not
required to resolve the bulk-import scan this issue reports.

Changeset Fragments

This directory holds per-PR CHANGELOG fragments. Every PR with user-facing changes drops one (or more) <random-name>.md files here describing its CHANGELOG entry. Fragments are consolidated into the top-level CHANGELOG.md at release time.

Why

Two PRs that both edit the ### Fixed block of CHANGELOG.md always conflict on merge — git can't pick a serialization order without human input. Two PRs that each add a fresh .changeset/<unique-name>.md never conflict because they don't share lines.

See #2975 for the full rationale.

Adding a fragment

node scripts/changeset/new.cjs \
  --type Fixed \
  --pr 1234 \
  --body "fix the thing — explain the user-visible change in one sentence"

This writes .changeset/<adjective>-<noun>-<noun>.md with frontmatter and a body. Three random words → concurrent PRs don't collide.

Format

---
type: Fixed
pr: 1234
---
**`/gsd-foo` no longer drops trailing slashes** — explain the user-visible change.

Allowed type: values follow Keep a Changelog: Added, Changed, Deprecated, Removed, Fixed, Security.

Opting out

PRs that legitimately have no user-facing impact can add the no-changelog label. CI honors it. When unsure, add the fragment.

At release time

node scripts/changeset/cli.cjs render --version vX.Y.Z --date YYYY-MM-DD

Reads every fragment, groups bullets by type:, replaces ## [Unreleased] with a new ## [vX.Y.Z] - YYYY-MM-DD block, opens a fresh ## [Unreleased] above, deletes consumed fragments. Idempotent.
