 ### Changed
 
+- **Active in-flight recovery snapshots are now sent in a compact transport form.** When you reload or reattach to a session with a run in progress, the `/api/session` payload no longer carries multiple redundant copies of each tool result and row value — it projects the live run-journal snapshot into a smaller, display-equivalent form (one authoritative source per value) while preserving the live message's timestamp so the reconstructed turn keeps stable identity. The durable journal and the canonical in-process snapshot are unchanged, so recovery renders identically with less payload. Thanks @allenliang2022. (#6858)
+
 - **Background-process completions and watch matches now render as compact, collapsible summary cards.** Routine wakeups no longer fill the transcript with an always-expanded agent-facing prompt: the collapsed row shows the command, exit status or matched watch pattern, and timestamp, while one click reveals the complete command and verbatim output. Failed processes keep a red accent, long watch patterns remain reachable on touch and keyboard when expanded, and unfamiliar future event shapes safely retain the existing raw-notice fallback. Thanks @b3nw. (#6350, #6345)
 
 - **The repository is now pip-installable with standard packaging metadata.** `pyproject.toml` gains a `[build-system]` + `[project]` section (setuptools + setuptools-scm) so packagers and distros can `pip install .` and get a proper wheel (`api` + `static` bundled). The normal `bootstrap.py` / `start.sh` / `ctl.sh` source-checkout launch path is unchanged. setuptools-scm writes its version to a separate `api/_scm_version.py` (not the Docker-owned `api/_version.py`), and the runtime version detector reads it as an explicit fallback (normalizing the PEP 440 value to a `v…` form) so an installed wheel reports a real version instead of `unknown` — Docker and git-checkout version resolution are byte-identical to before. Thanks @rodboev. (#6337, #2695)
