Snapshot: main @ 4174f3e, Arc 2 closed with #110 (framing revision 6,
two pre-branch + three PR rounds). Next action is the compile-mode vs
themes decision discussion — frame the tradeoff, don't pick. Pairing
deferrals consolidated into §6; new substrate noted (buf:path,
pmacs.lsp.buffer_language, PMACS_FAKE_LSP_CHANGE_SINK,
TestDaemon::spawn_with_config).

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.

RET now runs edit.newline-and-indent (builtin/runtime/indent.lua):
one insert/replace of "\n" plus the current line's leading whitespace,
copied verbatim and clipped at the split point (Q#AI3). Region RET
stays a single Replace (CUA type-over, one undo step, one CRDT op);
the selection clears after every successful edit (Q#AI4). Fix-up is
snapshot-guarded against context-switching intercepts and repairs the
cursor by right-gravity translation through the effective edit
(Q#AI5). buffer.newline remains the plain-newline escape hatch.
GPU (Q#AI1/Q#AI6): plain Enter is no longer optimistic-eligible --
its classifier arm's premise (byte-identical to a self-insert) died
with the new binding. Enter round-trips like the TUI, which also
makes global and buffer-local RET rebindings (buffer-list visit)
reachable from the GPU frontend.
Substrate fixes that RET would otherwise ship on top of:
- Q#AI8 search staleness: notify_buffer_edit now marks matches stale
and right-gravity-translates the live session origin, matching
apply_active_edit; SearchStore::step and search_match_summary fail
closed while stale (a live search un-sticks on the next pattern
keystroke, since set() clears staleness).
- Q#AI9 empty selections: insert_char reports success and the
no-region arm of insert_char_over_region clears a lingering anchor
only on Ok -- ordinary typing no longer type-overs its own previous
keystroke after S-Left at BOF, and a rejected insert mutates no
state.
Acceptance: tests/auto_indent_acceptance.rs (20 dispatch-driven
cases), tests/auto_indent_crdt_acceptance.rs (pending optimistic
input then round-tripped Enter converges on the source replica),
flipped GPU classifier test, and lib tests for the store, core, and
dispatch seams.
Framing: docs/auto-indent-framing.md (five review rounds).

docs/agent-handoff.md is the continuity bridge between development
machines: current state snapshot, the framing->review->gates->PR
working method, substrate invariants (command boundaries,
effective-edit returns, outbound_position, state-dir isolation),
machine-specific caveats to re-verify per box, ops lessons, and the
consolidated named-deferral backlog. Carries its own update protocol
so each machine hands it forward.
CLAUDE.md (auto-loaded by Claude Code on any clone) points there and
pins the always-true constraints: workflow, gate suite, shared-checkout
discipline, commit/PR conventions.
