stdio's pad_item patch was passThrough, so edits reached the CLI unread:
its JSON decode into bodypatch.Edit.LineHint (an int) refused a string
hint that remote coerces ("5"), and took a JSON number of 2^53 or more,
which mcp-go's float64 decode may already have rounded, as a line number.
Remote has validated each edit's line_hint since BUG-4065, inline in
mapItemPatch.
That loop is now editsWithLineHints, called unchanged by mapItemPatch and
by a new stdio action, actionItemPatch. On stdio:
- a valid hint is forwarded as its int64;
- a refusal is validation_failed with remote's message, naming the edit
("(in edits[1])");
- null is absent, and a non-object edit keeps its path.
Neither transport modifies the caller's map.
Tests (lead ruling 86931478): one table, bug4082Cases, runs every input
through both transports and requires the same forwarded edits or the same
refusal (C1). Remote's BUG-4065 rows stay green unchanged. A row on each
transport pins the caller's map (C2). Red on main: stdio forwards "010",
1.5, 2^53, true and {} raw while every remote half passes.
ToolSurfaceVersion 0.105 -> 0.106 (C3), with the changelog in version.go
and docs/mcp.md; the README and the instructions.md heading follow. The
wire goldens follow in the next commit.
