 ## [0.9.0] — 08-12-2026
 
+diffmind was built as a gate: run it, get a verdict, pass or fail. This release
+adds the other half — a place to *sit* while deciding what to say about someone
+else's branch. Both surfaces share one engine; neither replaces the other.
+
+### Breaking
+
+- **`--format json`: `stats.chunks` → `stats.units`**, plus `units_cached` and
+  `units_unparseable`. The unit of review is now a region of a file rather than
+  an arbitrary slice of lines, and the field names say so. Exit codes, SARIF and
+  Markdown output are unchanged, so CI gates are unaffected.
+- **Daemon protocol changed.** A running 0.8 daemon is ignored rather than
+  misused — the version gate already handled this — but you will want
+  `diffmind serve --stop` after upgrading.
+- **`chunk_diff` removed** from the `core-engine` public API, superseded by
+  `build_units`.

 ### Security

   Existing downloads are verified against the new pins on next use; the current

+### Added
+
+- **Code graph.** A tree-sitter symbol graph for 13 languages — Rust,
+  TypeScript, TSX, JavaScript, Python, Go, Java, C#, Ruby, PHP, C, C++ and
+  Scala — stored in `.diffmind/graph.db` and updated incrementally
+  by mtime. Replaces the regex symbol index, which could only see `pub`/`export`
+  declarations and had no concept of a reference at all.
+  Review context now includes **the callers of every changed symbol** — a
+  changed signature is judged against the code that depends on it — plus the
+  enclosing definition, referenced definitions, and the file's tests. Everything
+  stays inside a byte budget, so context does not grow with the repository.
+  Bodies are read from the working tree rather than stored, so a snippet can
+  never disagree with the file being reviewed. The graph refreshes itself
+  incrementally before every review (~0.1s on 647 unchanged files) and builds on
+  first use, so it can never fall behind the code; `--no-index` opts out. Adding a language is one entry in
+  a table; contributions welcome.
+
+- **Cross-file review units.** When a symbol and code that calls it both change
+  in one diff, they are reviewed together as a single unit instead of separately.
+  Reviewed apart, the model judges an interaction while seeing only one side of
+  it as background. One call replaces two.
+- **Reviewer's cockpit** (`diffmind --tui`). Analyses on launch. Each finding
+  shows the actual hunk the model reviewed and the context it was given.
+  `a` accepts (and copies a review comment via OSC 52, which works over SSH),
+  `d` dismisses, `w` marks wrong. Verdicts are written through immediately.
+- **Review standards as markdown** — `.diffmind/rules/*.md`, scoped by path
+  glob, committed to the repo. `diffmind rules init` / `rules list`. A finding
+  the model attributes to a rule set gets the ID `rulebook.<id>` and suppresses
+  like any other; an attribution naming a rule set that does not govern that
+  file is discarded.
+- **Reportable pre-filter.** Lockfiles, `linguist-generated` paths, `@generated`
+  banners, minified bundles, assets, snapshots and formatting-only hunks are
+  dropped before the model sees them — and the run says what it skipped:
+  `312 hunks → 74 reviewable (238 filtered: lockfiles, generated, formatting)`.
+  Whitespace inside a string literal counts as content; indentation is never
+  dismissed in Python or YAML.
+- **`diffmind stats`** — findings, cost and the accept-to-wrong ratio over
+  recorded runs. Every review is filed to `.diffmind/runs/<sha>/`.
+- **Cost reporting** — wall-clock and token counts in the footer, in JSON, and
+  in the run record. Estimated counts are marked `~` rather than passed off as
+  exact.
+- **Revision ranges** — `diffmind v1.2.0..HEAD`, or `--range`. Paths after a
+  range narrow it.
+- **`review.ignore`** globs in `.diffmind/config.toml`.
+- diffmind writes its own `.diffmind/.gitignore`, keeping generated state out of
+  git while leaving `rules/`, `rules.toml`, `config.toml` and `baseline.json`
+  committable. Your repository's `.gitignore` is not touched.
+
+### Changed
+
+- `Graph::definitions_of` is replaced by `definitions_of_names` (batched) and
+  `declarations_overlapping` (span-based). The "prefer a definition in this
+  file" rule moved to `rag`, where the file being reviewed is known.
+- `ReviewAnalyzer::analyze`'s progress callback takes the unit being reviewed:
+  `Fn(usize, usize)` → `Fn(usize, usize, &ReviewUnit)`. Callers that need to
+  show a reader the hunk behind a finding should record it here rather than
+  predicting the unit list with `plan_units`.

+- **A large rule set could fail the whole review.** Two faults compounding.
+  Splitting an oversized prompt halves the *diff*, but the context and rule
+  sections were sized from the window alone — identical at every recursion
+  level — so a prompt that overran because of its rules failed the same way four
+  times and then gave up. And giving up returned an error that propagated out of
+  `analyze`, exiting 2 and discarding the findings every *other* unit had
+  produced, including deterministic ones that never needed a model.
+
+  Both sections now shrink with each split (dropping whole rule sets rather than
+  truncating one mid-sentence), and are held to at most half of what the window
+  has left, so the diff under review cannot be crowded out. A unit that still
+  will not fit is counted in the new `units_too_large` stat and skipped, and the
+  footer says so. Unchanged for an ordinary review: at depth 0 on the shipped
+  32K window the budgets are exactly what they were.
