Remaining upstream v1.5.7 command-line surface outside multi-threading: - file selection: -r, --filelist, --output-dir-flat, --output-dir-mirror, --exclude-compressed; symbolic links skipped unless -f, as upstream does - ZSTD_CLEVEL sets the default level and ZSTD_NBTHREADS is validated, both read the way upstream reads them - -q / -v display levels with upstream's result summaries, "zstd: ..." error framing, per-input failure continuation, exit status 1 when any input failed and 2 on SIGINT, which also removes the partial output file - wire-format switches wired to the encoder: --[no-]check (also skips verification when decoding), --[no-]content-size, --no-dictID; --[no-]pass-through with the zstdcat / -dcf default; zstdcat and zcat take upstream's full preset (force, stdout, pass-through, quiet) - several inputs into one -o / -c are concatenated after upstream's warning and prompt; an existing output is asked about without -f and refused under -q; valued long options take the next argument as well as =value - -l columns match upstream (DictID moves to -lv, sizes in upstream's scaled layout), .tzst and .zstd suffixes, -h / -H split, -qV bare version Part of #128
LiteralCompressionMode (Auto / Enable / Disable) on the compression parameters builder, the drop-in equivalent of ZSTD_c_literalCompressionMode: Disable stores every literal section raw, Enable entropy-codes literals on the negative levels too, Auto keeps the level's own choice. FrameCompressor and StreamingEncoder carry the mode beside the target-length override and feed it to the raw-literals gate on every frame. Part of #128
- --zstd=wlog=#,clog=#,hlog=#,slog=#,mml=#,tlen=#,strat=#,lhlog=#,lmml=#, lblog=#,lhrlog=#: every knob through the compression-parameters builder, validated at the command line; a --zstd window wins over --long's, the LDM knobs apply with --long, and --long is admitted below level 16 when --zstd=strat= moves the level onto the optimal parser - --[no-]compress-literals wired to the literal compression mode - --patch-from REF: the reference as raw content on both sides, the window sized to the input (highbit + 1, within what this build decodes), ultra levels unlocked, long-distance matching on where the optimal parser runs; refused with -D, on several inputs, and on stdin without --stream-size - --train-cover runs the COVER trainer (its reference-side tuning is refused); --train-fastcover=k=,d=,f=,steps=,split=,accel= tunes FastCOVER the way the reference checks it; shrink is refused - -b prints upstream's result layout, with the -q machine line and header; -i defaults to 3 seconds; several files are named by their count - --rsyncable refused as incompatible with single-thread mode Part of #128

- `set_compression_level` cleared the strategy, target-length and matcher overrides installed by `set_parameters` but kept the literal compression mode, so a compressor switched back to a bare level still wrote the previous parameters' raw (or forced) literals. - Reset it to `Auto` with the other overrides; the regression test compares the frame after such a switch with a fresh compressor's. Part of #128
- `-r` under `-f` followed a link back to an ancestor round and round, listing each file once per nesting level until the path ran out of room. The walk now keeps the device and inode of the directories it is inside and reports a link that leads back into one instead of descending; the reference command (util.c, UTIL_prepareFileList) has the same loop. - The "every named input is a symbolic link" refusal fired before the `--filelist` entries were merged, failing a run whose list still named inputs. It is judged on the merged set now; upstream judges the named inputs alone (zstdcli.c, the followLinks block), a deliberate departure. - The SIGINT handler declared `signal` with a function-pointer type, so a returned SIG_IGN marker became an invalid `Option<fn>` value, and it replaced an inherited ignore. The disposition is an integer now, as C's sighandler_t is; a SIGINT the process inherited as ignored stays so, as gzip and xz keep it and as a background job of a non-interactive shell expects; `clear` restores what the first `guard` found. Upstream installs its handler unconditionally, another departure. - The same handler now runs on Windows through the C runtime's `signal`, `_wunlink` and `_exit`, removing the partial output and exiting with status 2 as on POSIX; only platforms with neither keep the no-op. Compiled and unit-tested for the Windows target; Ctrl-C delivery itself is not exercised by the tests. - `create_dir_if_missing` no longer declares a `mut` that only the Unix branch uses.

Apply symbolic-link filtering to file-list entries.
A directory symbolic link from --filelist reaches fs::metadata without the check used for command-line inputs. fs::metadata follows the link. Therefore, -r traverses its target even when follow_links is false.
Filter every merged input before recursive expansion. Add tests for file and directory symbolic links supplied through --filelist.

Serialize the signal-state tests.
super::imp::forget_inherited, take_default_action, ignore_interrupts, and clear modify process-wide SIGINT state and shared atomics. The standard test harness can run these tests concurrently, so interleaved setup and cleanup can produce nondeterministic assertions. Add one shared test lock for all Unix/Windows tests, or configure this test target to use one thread.

Summary
The remaining upstream v1.5.7 command-line surface outside multi-threading, checked against

-r,--filelist,--output-dir-flat,--output-dir-mirror,--exclude-compressed; symbolic links are skipped unless-f, as upstream does. Directory walks run in name order so two runs over one tree behave the same, and a link that leads back into a directory being walked is reported and not descended (upstream loops until the path runs out of room). One departure from upstream: whether anything is left after the symbolic links were dropped is judged once the--filelistentries are in, not on the command line alone.-o/-care concatenated after upstream's warning and prompt, with--rmset aside; an existing output is asked about without-fand refused under-q, where nothing can be asked.=value(NEXT_FIELDsemantics).Display, errors, exit status
