Groups B and C of the leftover-primitive cleanup — renames, not new machinery,
and deliberately NO unsafe_ prefix (a __-prefix is itself a C convention, and an
`unsafe` marker carries no signal in a fully-manual-memory language with no safe
subset to contrast against).
memory: mem_free -> free mem_realloc -> resize mem_set -> fill
ptr_add -> offset
process: os_argc -> arg_count os_arg -> arg os_exit -> exit
os_system -> run os_getenv -> getenv read_byte -> read_char
dead: mem_copy, os_time, write_byte (0 uses) — deleted
Two reseeds: accept both old and new names in the intrinsic dispatch, then
migrate every call site and drop the old names. file_open/read/write/seek/tell/
close are left as-is — they're the domain-prefixed syscall layer wrapped by
read_file, not the argc/argv-style C-ness the audit targeted; a `File` type is a
separate, larger design if wanted.
test.sh's CLI smoke updated (os_exit -> exit); check-vocabulary's grammar marker
moved off the deleted names. Reseeded (22243 lines); C-free fixpoint holds;
goldens identical; 18/18; vocab + doc-fences clean.

The last peek/poke pairs were the same "typed buffer access wearing a C name" as
peek8/peek32, so they become indexing too:
peekf(sc_x, i) -> sc_x[i] (a `fixeds` buffer -> a fixed)
pokep(gc_bmp, s,b) -> gc_bmp[s] = b (a `ptrs` buffer -> a pointer)
str_len(s) -> len(s) (len is polymorphic since 7f; str_len was dead)
Two new element-typed buffers join words: `fixeds` (32-bit fixed) and `ptrs`
(pointer, 8-byte stride). emit_index_addr dispatches on the base type; IR is
byte-identical to the old intrinsics.
The peekf/peekp buffers (ed_x0/ed_x1/ol_x/sc_x fixed coords; gc_bmp/img_px/
tt_data/ui_text pointer arrays) were retyped scope-aware, then the 33 sites
migrated to indexing. Two bugs found via a menu golden diff / a link-time type
error and fixed: the buffer-name regex truncated digit suffixes (ed_x0 -> ed_x),
and the char-literal brace-miscount skipped a few module declarations (same class
as 7j).
Reseeded (22371 lines); C-free fixpoint holds; goldens byte-identical; 18/18;
vocab (fixeds/ptrs types in, 5 intrinsics out) + doc-fences clean.

Answering your readability point directly: the compiler's own string-building —
left uglier by the 7c `+` migration, e.g. `emit_bind(("load i32, ptr " + ip))` —
now reads as interpolation:
emit_bind(("load i32, ptr " + ip)) -> emit_bind(`load i32, ptr {ip}`)
emit_bind(("icmp eq i32 " + (kv + (", " + itoa(ak)))))
-> emit_bind(`icmp eq i32 {kv}, {itoa(ak)}`)
perr(("assign to unknown " + t.s)) -> perr(`assign to unknown {t.s}`)
164 concat chains across selfhost converted by a tool that flattens the `+` tree,
keeps call/index parens (only grouping parens are rewritten), and converts only
**brace-free** literals — LLVM IR structure strings full of `{`/`}` stay as `+`
rather than becoming awkward `{{`/`}}`. No new language surface; interpolation
already desugars to the same concat.
Reseeded (22565 lines); C-free fixpoint holds byte-for-byte (the strongest proof
the reconstruction is exact); goldens identical; 18/18.

Strings are values now: `a + b` concatenates and `a == b` / `a != b` compare by
content, replacing the 605 `sconcat(...)` / `streq(...)` calls that made the
compiler read like C.
streq(name, "let") -> name == "let"
sconcat("load ", reg) -> "load " + reg
sconcat(a, sconcat(b, c)) -> a + b + c
Implementation: emit_bin gains a string path. Strings are pointer-typed, so any
`+` with a pointer operand concatenates and `==`/`!=` between pointers compares
content — except when one side is the `null` literal, which stays a pointer
identity test (the only two kinds of pointer `==` in the codebase). Both call a
small hand-written IR prelude, @fn_str_eq / @fn_str_concat, emitted once into any
program that uses string ops (so it works for tools, games and the compiler with
no runtime-splice dependency and no duplicate symbols).
Delivered as two reseeds: (A) add the operators + prelude with the full
pointer-aware dispatch, keeping streq/sconcat; (B) migrate every call site
(354 lines, via a string-literal-safe balanced-paren script that leaves the
function definitions alone) and delete streq/sconcat. examples/strings.ludic +
a test.sh smoke (prints 1 2 3 4 5) guard it.

The parser now requires a newline or ';' between statements (block() in
selfhost/parse.ludic); two statements may no longer sit adjacent with only
spaces. Also fixed if-without-else swallowing its trailing separator.
Migration: tools/ludic-tools/migrate_separators.c inserts ';' at statement
boundaries corpus-wide (examples, runtime, 25 self-host fragments, ~1100
boundaries). Verified semantically identical — the migrated compiler compiles
itself to IR byte-identical to the pre-migration seed, and every golden game
renders identically. Reseeded to the strict compiler; C-free fixpoint holds;
test.sh 14/14.
Docs: Rule B documented in LANGUAGE.md; BOOTSTRAP.md R1 + stale fences updated;
check-docs green across all docs. Fixed a multi-line string literal in
emit_expr.ludic (byte-identical \n escape) that the C toolchain lexer mis-lexes.

Self-hosted compiler (selfhost/*.ludic), runtime, examples, editor tooling,
and docs. Phase 1 of the syntax-redesign cohesion pass has landed:
edge-system fix, signature-query, when-alias, and the documentation truth-pass.
Suite green (14/14), C-free bootstrap fixpoint holds.
