#35 (fold-5 blocker, PG6): the append() spread arm dispatched on SOURCE node kind — ident-local only; both fold-5 dup shapes loud-rejected on BOTH stages: deref-spine `append(dup, (*tsp)[0].caps...)` (add_thread regex.ha:569/572) and indexed `append(res, ts[0].caps...)` (search ha:820). Route every non-ident-local source through cgplaceaddr (the established place choke-point: C1 stores, C1.25 aggregate fields, FA1 append targets, #49 element sources): the source header ADDRESS resolves ONCE, pre-grow, into a fresh per-site @appsprscr spill, and every loop iteration re-reads .ptr/.len THROUGH the spilled header after the grow. This adapts the #49 split ruling to the spread's full-range copy: the chain's rvalues (deref-root pointer expr, index exprs) evaluate exactly once PRE-grow — an index reading the dst's len sees the pre-append value — while the source data base and len re-derive live each iteration, so a source header aliasing the dst header re-roots post-realloc. A header reached through a buffer the grow reallocs reads the STALE copy — bit-identical under the non-reclaiming rt/malloc, the same documented #49 stale-base hole (pinned by the spread_selfalias_chain row). Ident-local sources keep the legacy BP-disp emission byte-identical. New loudness with the same fix: the spread source's stamped type must chase to TY_SLICE/TY_STR — a [N]T array ident source previously read its first 16 DATA bytes as a {ptr,len} header, silently. Array wiring plus the remaining rvalue sources (CALL, slicing exprs) stay loud, filed task #27. Global-ident sources now resolve on cstage but are blocked by a pre-existing wwstage checker reject ("let: not assignable", task #29) — no dual-stage row until that closes. 806_append_place: reject_spread_src GRADUATES to a runtime row (spread_place_deref, the old reject source verbatim + readback); new rows spread_dup_copy (PG6 verbatim: both fold-5 shapes, 56B capture elements, copy-semantics mutation pin, want 139), spread_place_kinds (str 24B headers / narrow i32 / empty deref source), spread_growth_place (40-elem spread crossing cap doublings), spread_selfalias_chain (source header inside the dst's grown buffer), and the two new loud-tail rejects (CALL rvalue, [N]T array) pinning the "#35:" diagnostic on both stages. 87 fixtures green (was 70), per-row cs/ww asm byte-cmp included. Unblocks regex fold-5a: add_thread regex.ha:569/572 + search ha:820 spreads go from loud-bound to real spread.
