Ctrl+Z after a peer's edit no longer reverts (and re-broadcasts) the
peer's work, and the adopt undo-bomb is gone:
- doApply/doApplyItems (both editors) Push with SKIP_UNDO; the emit path
is unaffected (suppression keys off s_applyingRemote, not undo).
- With SKIP_UNDO no picker owns removed items — the bindings free them
after Push (explicit removals + upsert's remove-before-re-add; fields
excluded: CHT_REMOVE hides them, parent keeps ownership). Freeing stays
out of the fork commit classes so DRC's SKIP_UNDO callers can't
double-free.
- Test hooks kicadCollabTestUndo/UndoDepth, registered per-editor AND in
the kicad_editor dispatcher (merged image compiles out per-app
registrations).
- kicad pointer: eeschema UUID undo guard + SKIP_UNDO connectivity split
+ quiet stale-entry drop (ca8877324c).
- tests/kicad/collab-undo.spec.ts: 5 scenarios (no undo entry from remote
applies; selective undo; stranded replaced/deleted entries) — 5/5, plus
collab/ysync regression 30 pass.
- docs: ysync-review 20 fix record; 09 marked FIXED; overview indexed.

Verdict: ~3-5 days. pcbnew undo already UUID-guards stale pointers; core
work = porting that guard to eeschema, splitting connectivity out of the
SCH SKIP_UNDO gate, plugging the SKIP_UNDO removed-item leak, silencing
the incomplete-undo modal. Cross-linked from 09 and the overview index.

New doc 16: the full repro-suite map (per-bug unit/e2e paths with verified
failure sites), the phase-C probe outcome, and four findings only the RUNNING
system revealed:
- F1: bug 03's sending half emits NOTHING — a child-only delete commit never
triggers a flush at all (worse than the doc's predicted bare removed-wire);
the GetWidth-assert tracer evidence and the fix implication.
- F2: Firefox cannot host two kicad_editor tabs in one context (per-process
wasm budget) — bug-01 two-tab repros are Chromium-only.
- F3: headless emit WORKS on both pcbnew and eeschema — the legacy two-tab
skip rationale and items-bridge localEdit omissions are stale.
- F4: drift-detect is strictly ITEM-silent on the green path (no writer-
formatting false positives).
Cross-updates: 00 index + verdict note; 01/04/05/06/07 Verification sections
gain their repro paths; 02 upgraded to runtime-CONFIRMED; 03 gains the F1
empirical correction; 11 (no v2 e2e coverage) CLOSED with a point-by-point
status update — only the legacy retirement remains.
