The flip: FUNCTION/XFUNCTION/FUN::fun/delim_check and the module
interfaces take `const UTF8 * const fargs[]`. Double-const is
load-bearing: C++ qualification conversion needs const at both pointer
levels, so builder-side `UTF8 *[]` arrays convert implicitly — the
evaluator, the JIT marshaller, and every owner site need zero casts,
and slot reassignment inside bodies becomes a compile error for free.
The conversions: the flip landed first so the compiler enumerated every
violation; this commit is that inventory worked to zero — ~250 sites
across funceval, funceval2, functions, funmath, help, mail, session,
powers, levels, predicates, conf, walkdb, stringutil, timeutil/
date_scan (regenerated, one-line diff), exp3, and mux_main, each
classified per docs/campaign-2136-const-fargs.md's four recipes.
New idioms (functions.h): trim_space_sep_n() — non-destructive trim for
(pointer, length) consumers, so trim-then-scan sites need no copy at
all; FargVec — the argv counterpart of FargCopy for CS_ARGV handlers.
countwords() and DecodeListOfIntegers() rewritten non-destructive.
The flip deleted more than it added: #2157's fun_munge list1 copy, the
engine_com help-topic copy, fun_index's in-place NUL write, and five
const_casts (process_sex x4, sha1_helper). const_cast budget: zero
added.
Trap recorded in the brief: an old-signature definition doesn't fail
the build — it becomes a C++ overload, and the new-signature symbol
stays undefined until dlopen(RTLD_NOW). delim_check, the conn_bridge
bridges, the dbt_spike stub, and exp3::Call were all silently shadowed;
muxscript was the only host that noticed, because netmux's own net.cpp
resolved the flat-namespace lookup. After any signature flip, grep the
old spelling.
Verified: make test EXPECT_CONFIG="jit=yes" (35 passed / 0 failed) and
make test-scenario, including the new tests/scenario/sidefx_fargs.py
that live-probes the class-3 wrappers smoke never touches (pemit/
trigger/link/tel/wipe/destroy).

Maintainer direction: prefer int64_t over long/int for parsed softcode
and attribute integers so LLP64 and LP64 behave the same.
This first slice covers the leftovers called out on the issue:
- quota: store/show/set paths (avoids @quota/all 2^32 writing 0)
- A_CHARGES in set/levels/predicates (RUNOUT vs wrap-to-positive)
- semaphore counts and @ps/queue kick/warp parsing
- IDLETIMEOUT attribute seconds
Bounded API edges (RunTasks(int), optional int *pnum) clamp after the
full-width parse. pot: quota notify formats use %lld.
Replace ~900 typographic \xE2\x80\x.. escapes (curly quotes, en dashes)
and a few \xE2\x80\230 octal workarounds with real UTF-8 in message
strings under mux/modules and mux/src. Leave stringutil and convert
charset mapping tables as explicit byte sequences.
Completes the sweep the issue called for. mux_atol returns long, which
is 32-bit on LLP64, so every caller silently truncated on Windows. Two
of those were real defects (the truthiness family and cf_size, fixed in
the preceding commits); the rest were latent, waiting for a value large
enough to matter.
Rather than audit 290 sites for whether each can reach 2^31 today, use
the 64-bit parser everywhere and remove the class. A dbref cannot
overflow now, but nothing stops a later caller passing that same site a
timestamp or a byte count.
Pure 1:1 substitution: 285 lines changed, and every removed line
contained mux_atol while every added line contains mux_atoi64. No
control flow, no types, no behaviour beyond the wider parse.
This is a NO-OP on LP64 -- long is already 64-bit on Linux and macOS, so
the generated code there is unchanged. It only widens the parse on
Windows. Narrowing destinations are unaffected either way: `int x =
mux_atoi64(s)` truncates exactly as `int x = mux_atol(s)` did, on both
models.
Left alone: mux_atol itself in mathutil, its declaration, and three
comments that name it. Callers that genuinely want 32-bit semantics can
still ask for them; none appear to.
Verified on Windows: full solution builds clean with no new warnings,
smoke is 1418 passed / 16 failed / 0 crashes / 306 of 306 dispatched --
identical to before the sweep, with the same 16 build-configuration
failures (exp3 module not loaded, hmac/digest behind UNIX_DIGEST).
Spot checks after the change: the boolean family returns 1 for multiples
of 2^32, cf_size round-trips 3000000000 and still reads -1 as unlimited,
and arithmetic, string and list functions are unchanged.

Use the new LBuf_Adopt() macro to take RAII ownership of caller-owned
pool buffers returned by atr_get, atr_pget, and atr_get_LEN. This
eliminates ~82 explicit free_lbuf calls and automatically covers
early-return paths that previously required careful manual placement
of the free.
Heaviest conversions: player.cpp (13), comsys.cpp (14), command.cpp (9).
Complex interleaved patterns (did_it charge/runout swaps, PureName
reassignment, process_cmdent loops) left manual for now.

Second wave: convert manual alloc/free pairs in cque (1), db_rw (4),
conf (5), db (2), engine_com (6), help (7), levels (2), predicates (5),
player (7), funmath (8). Eliminates ~80 explicit free_lbuf calls
including multi-exit error paths in getboolexp1 (5 frees → 0),
get_list, AnnounceConnect/Disconnect, and the eight NOEVAL function
variants (cand/cor/firstof/allof and bool variants).
