Patchloom 0.27.0
Clearer agent recovery after failed writes, and machine-stable hints when a
doc write selector uses a predicate or wildcard.
Highlights
Library hosts can read a backup session id from a failed apply path so
fail-restore and undo do not scrape English error text. When doc set,
doc ensure, or doc delete is called with a predicate or wildcard
selector, JSON output can include suggested_op (doc.update or
doc.delete_where) so harnesses can retry the right multi-match op without
parsing messages. That mapping also holds when the predicate is an intermediate
parent path, not only a leaf segment.
New features
- api::backup_session_from_error. On a failed write after a backup was
created (for example a post-write --format failure), hosts can peel the
session id from the error for fail-restore. Success paths already expose
EditResult.backup_session; the Err path is now first-class.
(#2129, #2131)
- suggested_op on fail-closed write navigation. Predicate or wildcard
selectors on single-path doc writes stay error_kind: invalid_input and
may set suggested_op to doc.update (set/ensure) or doc.delete_where
(delete). Plan/tx and MCP JSON preserve the field. Move has no multi-match
sibling and omits the field. Intermediate parents use the same mapping as
leaves.
(#2136, #2137, #2140)
Bug fixes
- Tx JSON could drop suggested_op after re-wrap. Fail-closed predicate
navigation still surfaces the hint on CLI and library peels after plan
error packaging. (#2137)
- Intermediate predicate always suggested doc.update. A delete (or
move) path such as items[id=a].val no longer invents an update retry;
delete suggests doc.delete_where, and move omits suggested_op.
(#2140)
Docs
- Agent and reference guidance for doc set vs doc update, and when to
branch on suggested_op. Intermediate mapping documented on set/delete.

Upgrading
- Library hosts: on apply Err after a backup, use
api::backup_session_from_error(&err) (or the crate re-export) instead of
parsing Display for a session id.
- Agents / harnesses: on invalid_input from doc write navigation,
read suggested_op when present. Do not assume every intermediate
failure means doc.update.
- Install from crates.io, npm, Homebrew, or Scoop after the tag ships.
Winget and Chocolatey may lag. Fresh Homebrew installs are checked in
release CI; local cellars still need brew upgrade when an older
formula is already installed.
