 ## [Unreleased]
 
+### Packaging
+- One package, `gridsift`, now carries both binaries: `cargo install
+  gridsift` installs the desktop application and the command-line tool,
+  and `cargo run` starts the application (`default-run`). The
+  `gridsift-desktop` package is gone; the binary names are unchanged.
+
+### Analysis cache
+- Whole-file results are kept in the user cache directory beside the index
+  sidecar: the file-wide column profile and value counts (`*.gsan`) and
+  the timelines over all records (`*.gstl`, read only when a timeline is
+  asked for). The next open of the same bytes — same
+  size, modification time and SHA-256 — shows the dashboard and timeline
+  at once and starts no profile pass; `freq`, `timeline` and `profile`
+  report `cached`. Counts over a selection or of derived columns are
+  always recomputed, and a changed file never uses the cache.
+
+### Files without a header
+- The sniffer's reading of the first record can be overridden everywhere:
+  `--header` / `--no-header` on the desktop launch line as on the command
+  line, and a click on *header* / *no header* in the sidebar reopens the
+  file the other way. `--names a,b,c` (command line and desktop launch
+  line) and the sidebar's *name columns…* dialog name the columns of a
+  file without a header; the names resolve `-c` and are recorded in the
+  manifest of every export (`source.dialect.names`), never in the file.

+- The analysis dock is open from the start, on *Values*, now the first tab
+  and with its own column picker; *Analysis* in the command bar hides and
+  shows it. The dashboard is built from the file-wide profile and
   counted in the background, on screen or not, so opening it shows current
   charts at once; the panels are counted one after another (one count's
   memory instead of six), and a timeline the analyst moved to another
