POST /workspaces/{ws}/items/{ref}/patch {edits:[{old,new,line_hint?}],
expected_seq?} replaces exact text in the body. It runs through updateItem,
so it takes every PATCH guard; the body is computed inside the store
transaction from the row it replaces. Each old must occur exactly once;
edits apply in order, all or nothing; every patch writes a version. The
answer carries a unified diff of what changed.
expected_seq does not refuse: a moved seq is applied over when the
anchors still match, and answered rebased with the intervening writes,
read from a seq chain stamped into item activity entries ({prev_seq, seq,
version_id}). complete is decided at runtime, so any write that left no
stamp reads incomplete; a guard test classifies every seq-moving store
statement. Refusals write nothing: patch_anchor_missing,
patch_anchor_ambiguous, patch_room_open (an open editor; step 2).
CLI: pad item patch, pad item show --lines. MCP 0.87 (additive):
pad_item.patch, get lines, three allow-listed codes. The timeline treats
the chain and patch keys as bookkeeping, not a change.
