Auto-pairing framing at revision 3 (two pre-branch review rounds):
pair chars leave both optimistic classifiers and round-trip through
dispatch (adjacent daemon-peer undo units, real type-over, no
transient skip paint); reaction hook pair.lua loads before lsp.lua
so the synchronous sighelp didChange flush ships the closer; exact
one-shot typed-edit provenance (pmacs.editor.take_typed_edit) gates
pairing fail-closed against transformed, relocated, or
context-switched source self-inserts and non-typed origins.
Handoff: main @ 7e127ab (auto-indent #109 merged), auto-pairing in
flight on this branch, Arc 2 deferrals consolidated into §6.
