Typing an opener inserts the closer with the cursor between; typing a
closer over its twin steps over it. Q#AP1: the nine built-in pair
chars leave both optimistic classifiers (shared charset in
pmacs-protocol) and round-trip through dispatch, so the opener and the
hook's closer are adjacent daemon-peer undo units, dispatch CUA
type-over applies, and skip never paints a transient duplicate.
Q#AP9: exact one-shot typed-edit provenance. EditorCore's
apply_active_edit now returns the effective Edit; the dispatch
fallback arms a per-frontend record (codepoint + requested vs
effective ranges + post-cursor + clean verdict) that insert primitives
complete and the daemon's optimistic CRDT arm builds directly. The
record is takeable exactly once via pmacs.editor.take_typed_edit()
during the one after-edit fan-out, then cleared — paste, programmatic
edits, manual hook runs, nested re-runs, rejected edits, and stale
this_command all observe nil, and transformed / relocated /
context-switched source self-inserts fail closed with a status.
pair.lua (loaded BEFORE lsp.lua — ordering contract in editor.rs):
per-language pmacs.pair.sets with a conservative default (no ' or `),
EOL/whitespace/closer insertion predicate, reactive skip-over-close,
rejected/transformed intercept outcomes with context-guarded
translate-and-clamp cursor repair.
Acceptance: 32 dispatch-driven cases (predicate, skip, per-language
sets, non-typed provenance incl. production-shaped paste, type-over,
undo/redo grain, intercept outcomes on both the source and reaction
edits, context-switch probe, record lifecycle, frontend isolation) +
first-didChange ordering against the fake LSP's sighelp mode via a
new PMACS_FAKE_LSP_CHANGE_SINK replay file. Six two-replica CRDT
cases pin dispatch-route convergence with cursor-between, undo/redo
walking the pair on both replicas, both mixed-history undo models as
named substrate limits, and the optimistic custom-char route
(closer-broadcast-before-opener convergence, degraded cross-peer
undo). TestDaemon gains spawn_with_config for init.lua-extended pair
sets.
