+# jpdev v0.8.0
+
+This release makes a check run proportional to a change, adds an opt-in duplication check, and
+turns the kit's own policy vendor-neutral

+
+## Checks proportional to a change
+
+`jpdev check --changed [BASE]` runs only the check-list steps that `jpdev.json` maps the changed
+paths to, taking the paths changed since the merge base of BASE (the default branch when
+omitted) and HEAD, in the working tree, the index and HEAD together. The whole list runs when a
+changed path is unmapped, when `jpdev.json`, the manifest or the runner itself changed, when
+nothing changed, or when the repository has no mapping. A missing merge base (a shallow clone,
+an unknown base) is a refusal, never "nothing changed". The vendored runner
+(`scripts/dev/check.sh --changed`) does the same through a vendored copy of the selection code
+that the kit's tests and the release workflow hold to the library.
+
+On pull requests the CI template now runs `--changed` against the base branch; a push to the
+default branch and a manual dispatch run the whole list, and only those record release evidence.
+`jpdev version` prints the kit checkout's description; an unknown option names it, so a kit
+without a feature says so.
+
+## Duplication check
+
+An opt-in `duplication` step reports copied blocks across a repository's declared languages, with
+per-repository thresholds (`min_tokens`, `min_lines`, `max_file_bytes`), an explicit ignore block
+for copies that are meant to stay, and a size bound with a named refusal when memory runs out.
+Each token run keeps its most recent places and one place that spans `min_lines` lines on its
+own, so a real pair is reported whatever sits between its two copies. Binary files and files
+over the size bound are named and skipped. The kit runs the check on itself.
+
+## Policy
+
+The model that builds or reviews is chosen by use case; a particular vendor's runner is one way
+to run a build, not the default. The policy's "who builds and who reviews" section says what a
+builder, a reviewer and a coordinator each own, independent of the tool that runs them.
+
+## Operating limits
+
+The duplication check covers a copy only where at least one `min_tokens` run spans `min_lines`
+lines on its own; a copy denser than that is covered by the recent-places window alone. Memory
+across many files under `max_file_bytes` is bounded only by the refusal. `jpdev clean` keeps the
+limits of v0.7.0.
