A response is built for one request and the graph never retains it, so there
is no entity for a handle to point at. The child holds a real instance
instead, revived from the object record the wire carries, and collect() frees
the copy each world holds — which is what that method is for. The
value-object rule rejects the class only because collect() assigns to $this,
so the category comes from an overrides.list entry.
HttpDownloader::get() and copy() answer with one.
Two gaps stay: decodeJson() reaches Composer\Json\JsonFile, which a guard
shadows, and Composer answers a curl request with the CurlResponse subclass
where this port flattens the value into a Response.

Composer reaches this class two ways: the object graph hands one out through
Composer::getLoop()->getProcessExecutor(), and plugins write
`new ProcessExecutor($io)` freely. Both bind to a Rust-side entity, so the
timeout the run shares -- seeded from process-timeout and rewritten while the
run is in flight -- has one value instead of one per world, and the executor
can still be passed to the classes that take one (`new Filesystem($process)`).
Three things the stub generator was missing came with it:
- By-ref parameters. The call carries their positions and the answer carries
what each holds afterwards; a position the answer omits was never assigned
to, which is what PHP does with an untouched by-ref parameter.
ProcessExecutor::execute is the only one on a proxied class.
- Argument arity, reproduced where the real body reads func_num_args().
execute($cmd) forwards the child's output and execute($cmd, $out) captures
it, and nothing but the argument count separates the two.
- Static methods that cannot run in the worker. One that reads a static
property the Rust side owns, or that reaches a guarded class, forwards
through __shirabeCallStatic instead of being materialized. That also fixes
Filesystem::isLocalPath and getPlatformPath, whose materialized bodies
called the guarded Composer\Util\Platform.
The async surface stays an explicit error. executeAsync resolves its promise
with a Symfony Process, whose proc_open() resource and pipes belong to
whichever process called start(), so a Rust-side spawn has none to hand back;
running the real start() in the worker needs a promise representation that
crosses the boundary unresolved.
The fixture project drives the whole synchronous surface from plugin code and
compares the trace against upstream Composer byte for byte.

Silencer only lowers the PHP error_reporting() level and re-throws
whatever the guarded work raises. A region that never reaches the PHP
runtime has no level to lower and emits no diagnostic on failure, so
wrapping it is indistinguishable from running it unguarded.
The pair kept in Application::hint_common_errors brackets a
getComposer() call, which loads installed plugins and dispatches
PluginEvents::INIT.

tokio's File returns from write_all once the blocking write is queued, so
the tail of the response body was still in flight when the download future
resolved. The caller then renamed the file, stat'd it and copied it into
the cache, so a package could land in the file cache truncated. The first
run still extracted the complete file and only a later run reading that
cache entry failed with "End-of-central-directory signature not found".
Flushing also surfaces the last write's error, which used to be dropped.

Comments that pointed at design notes kept outside the repository are dead
ends for anyone reading only the tree, so what each of them explained now
lives in a tagged TODO at the site it applies to. Several of those sites
also stated something the implementation does not do, and the TODOs record
the actual gap instead: the two halves of the codec recognize handle
descriptors by different rules, the scripts Command path drops the exception
class and collects output in a BufferedOutput that cannot carry an
interactive command, find_shortest_path panics where PHP throws, and the
package dispatch hand-rolls the variant selection AnyPackage should own.
The classifier document likewise described rust-snapshot,
plugin-constructible and several of the open questions as designed rather
than as built.

file_get_contents() and file_get_contents_with_max_length() return
Vec<u8> instead of a from_utf8_lossy'd String.
Call sites whose consumer takes a &str still convert lossily and are
marked TODO(bytes).
file_get_contents_with_max_length() now reads at most the requested
number of bytes instead of the whole file.

Composer shells out to `rm -rf` because PHP has no recursive directory removal.
Rust has one, and every package installed from a dist archive pays for a removal:
the extraction pipeline drops its temporary directory once per package, and
uninstalling a package removes its whole tree.
The asynchronous path goes through `tokio::fs` rather than `std::fs`, so the walk
runs on a blocking thread and the sibling installs the reactor is driving keep
making progress, the way they did while the subprocess was working.
Installing laravel/laravel (109 packages) from a warm cache drops from 3.85 to
3.19 CPU seconds. The removals run concurrently, so on an idle 16-core machine
they never reach the critical path and wall time is unchanged at 1.65 s; pinned
to two cores it falls from 2.33 s to 2.20 s. Pruning the 33 dev packages with
`install --no-dev`, where whole package trees are removed rather than empty
temporary directories, drops from 844 ms to 806 ms even on 16 cores.
Windows keeps the `rmdir /S /Q` subprocess, and both platforms keep falling back
to `remove_directory_php` when the fast path does not clear the directory.

Messages that instruct the user to run a command named the Composer
binary. Shirabe ships as its own binary, so the hints now name it.
File names (composer.json, composer.lock), the "composer" repository
type and prose about Composer itself are untouched. The installer and
functional integration fixtures live in the Composer submodule and
cannot be edited, so their expected output is normalized on load.

PackageInterface::getRequires() and friends return the array of Link objects;
in PHP that is a copy-on-write array of object references, so a caller pays
nothing to look at it. The port returned IndexMap<String, Link> by value, so
every call deep-cloned the whole map, keys and constraints included. Pool
building calls these accessors once per package per candidate, which put
IndexMap::clone at 13.5% of `require laravel/laravel`.
Store the maps as Rc<IndexMap<String, Link>> and return a handle. Callers that
mutate the map clone it explicitly at the point of mutation, matching where PHP
would separate the array.

CurlDownloader built a fresh reqwest Client, and with it a fresh
connection pool, on every construction. A `require` run constructs two:
RequireCommand::doUpdate discards the Composer instance that
BaseCommand::initialize built and rebuilds it against the rewritten
composer.json, so the second one opened a second TCP+TLS connection to
the same repository and paid another CA bundle parse.
Nothing in the constructor varies the Client -- `options` and
`disable_tls` are not applied to it -- so it can be shared. The cache is
keyed by tokio runtime rather than by process: a pooled connection is
driven by a task on the runtime that opened it and hangs if it is later
handed to another one, and `sync_executor::block_on` builds a disposable
runtime per call outside `main`.
Measured on `require monolog/monolog` in a git-managed project against a
warm cache: TLS connections to the repository drop from 2 to 1, taking
the run from 646 ms to 529 ms with the network and from 104 ms to 101 ms
offline.

`ProcessExecutor::execute_args` existed only to turn `execute`'s
`anyhow::Result` into an exit code of 1, so every one of its ~87 call
sites silently took the "command failed" branch on an error PHP would
have thrown. It is gone; callers use `execute` and propagate with `?`.
Where the enclosing function had no `Result` to propagate into, its
signature grew one, up to and including `Git::get_version`,
`Svn::binary_version`, `GitHub`/`GitLab`/`Bitbucket::authorize_oauth`,
`InitCommand::get_git_config` and `DiagnoseCommand::check_git`.
The VCS drivers had the same problem in the other direction: their
`get_contents` returned `Result<Response, Box<TransportException>>`, a
type too narrow for the PHP method, which lets any Throwable out of the
`catch (TransportException $e)` block. Every non-transport error was
therefore rewritten into a `TransportException` with code 0, which the
callers switch on. They now return
`anyhow::Result<Result<Response, Box<TransportException>>>`: the outer
`Result` carries what PHP does not catch, the inner one the exception
the drivers handle.
That signature also restores `GitLabDriver::getContents`: the 400/401
`TransportException`s it raises to force authentication are thrown
inside its own `try` block and handled by its own `catch`, but the port
returned them straight to the caller, so the authentication flow behind
them never ran.
`impl_php_exception!` gains `From<Box<$ty>> for anyhow::Error` so a
caught exception can be re-propagated with `?`.

Commands were carried as `PhpMixed`, whose `String`/`List` variants do
not tell a shell command line apart from an argv list at the type level.
`Perforce::execute_command` and `Git::run_command` therefore funnelled
string commands through `execute_args`, spawning `p4 set` or
`git command` as a single argument instead of running it through a shell
as PHP does; their tests were written against that shape.
Introduce `CommandLine::{Shell, Args}` and use it for every
`ProcessExecutor` entry point, the mock expectation queue and the
`Git::run_command` callables. The unreachable "Invalid command type"
branches disappear with it, and the affected tests go back to the string
expectations the PHP suite uses.

function_exists() returns false in PHP when a function is blocked by
disable_functions, when its extension is not compiled in, or when the
PHP version predates it. None of those apply to a native binary.

The capture groups were discarded at 162 of the preg_match call sites,
which only tested the Option. They now call preg_is_match, which lets the
regex engine skip capture tracking.

Every call site but one passed offset 0. The remaining one, the UTF-8
chunking loop in Application, slices the subject instead: its pattern has
no anchor or lookaround, so matching a suffix is equivalent to starting
the search at that offset.

Preg had shed everything it owned: after the last few rounds its methods
were one-line forwards to the shim's preg_*(), differing only in a
default argument or a wrapper the caller unwrapped anyway. The 460 call
sites now name the shim function, and shirabe-pcre is gone from the
workspace along with its LICENSE entry.
The forwards expand as they read: isMatch becomes
preg_match2(.., 0).is_some() (is_none() where PHP negates it), isMatch3
and match3 drop the .is_some(), matchAll counts through
preg_match_all2(..).occurrence_count(), and replace4/replace5 spell out
the limit and count arguments preg_replace2 takes. Callbacks are the one
place the shapes differ: preg_replace_callback carries an error out of
the callback, so the fourteen infallible closures wrap their result in
Ok() and expect() it back.
Config::process() is the fifteenth, and it drops the `error` cell it
captured to smuggle a failure past a closure that could only return a
String. The `?` in the closure now carries it, which is what the PHP
does -- a throw from the callback leaves preg_replace_callback at the
failing match rather than running the remaining replacements and
reporting the last error.
The module doc that explained why composer/pcre's exceptions and
*StrictGroups() variants have no counterpart moves to the shim's preg
module, where the functions it describes live.

PregMatches keyed both forms of a capture group through CaptureKey, so
every read built one: a usize wrapped in an enum, or worse, a String
allocated to name a group that regex::Captures can look up from a &str.
It now mirrors regex::Captures instead -- get() takes the group number,
name() the group name -- and the enum drops out of the type entirely.
That is 285 call sites across 59 files, and the named ones carry most of
the win: `matches.get(&CaptureKey::ByName("host".to_string()))` reads as
`matches.name("host")`. ProcessExecutor loses a `user_key` binding that
existed only to build the key once.
CaptureKey stays as the key type of PregMatchesAll and
PregMatchesAllWithOffsets, where numbered and named entries share one
IndexMap and a key type is the point. Five files still name it.
Also retargets the two preg_match_all comments that described the
occurrence count through `matches[&CaptureKey::ByIndex(0)].len()`, an
Index impl these types no longer carry.

is_match_named and is_match_with_indexed_captures reshaped a match into
a name-keyed map or a number-positioned vec, each allocating a String
per group up front for callers that then read one or two of them. Every
one of the eleven call sites ports a plain Preg::isMatch in PHP, so they
now call is_match3 and reach for the group they want through
get(&CaptureKey::ByIndex(N)) / get(&CaptureKey::ByName(..)), the same
way the rest of the tree already reads a match.
Falling out of that: PregNamedGroups existed only to type the first
variant; PregMatches::iter() only to build both; and PregMatches::pattern
only to give iter() the capture names. PregMatches is now a plain
wrapper over regex::Captures, so preg_replace_callback no longer clones
the resolved pattern for every match, and preg_match_map! is internal to
the shim again.
SvnDriver::get_file_content and get_change_date recover the flat
`isMatch(..) && $match[2] !== null` condition the PHP has, which the vec
shape had forced into a nested if.

Preg::match4 and Preg::replace_callback gave callers a
PregMatchedGroups: an IndexMap rebuilt from the match with an owned
String per group, plus a second String for a named group's name key.
That is the copy PregMatches shed when it started wrapping
regex::Captures, reinstated one layer up -- and nearly every regex call
in the tree goes through Preg rather than the shim's preg_* directly, so
almost nothing saw the borrow.
PregMatchedGroups existed only to drop the null (unmatched) groups the
old PregMatches held as Option<String> values. PregMatches::get reports
a non-participating group as None on its own, so the two read alike and
the type collapses into it. Call sites still reach groups through
get(&CaptureKey::ByIndex(N)); what changes is that the value arrives as
a &str borrowed from the subject, which the signatures now carry as a
lifetime.
Three places needed the borrow reckoned with rather than a mechanical
rewrite: PhpFileCleaner::clean and Problem::get_messages read their
groups out before mutating what the match borrows, and
Git::get_authentication_failure names the lifetime of its url argument,
which the result borrows instead of self.

`Composer\Pcre\Preg` fills `$matches` through a by-ref parameter, and the
port mirrored that with a `&mut` (or `Option<&mut>`) out-param plus a
bool or count return. Callers had to declare an empty map one line ahead
of the call, and the type never said the map is only meaningful when the
call matched. Return the matches instead:
- match3/match4/is_match3/is_match4 -> Option<PregMatchedGroups>
- is_match_named -> Option<PregNamedGroups>
- match_all2/is_match_all -> PregMatchesAll
- is_match_all_with_offsets3 -> PregMatchesAllWithOffsets
Nothing is lost: the bool is `Option::is_some()`, and the occurrence
count is the length of any one column of a PREG_PATTERN_ORDER map, now
spelled `PregMatchesAll::occurrence_count()`. is_match() still answers
the bool question directly for callers that want no groups.

The shim carried two reporting modes for the preg_* $matches maps: PHP's
default (trailing unmatched groups dropped, interior ones ""), and the
PREG_UNMATCHED_AS_NULL form, picked by calling a *_unmatched_as_null()
variant. The regex crate hands out Option<Match>, which maps onto the
null form directly, and no caller distinguished a dropped group from a
null one -- preg_match() and preg_match_all2() already reported nulls
unconditionally. Keep only the null form; the shim API no longer mirrors
PHP's flag set, which is intended.
Preg::is_match_with_indexed_captures() modelled PHP's "unset" as a
truncated Vec<String>, and now returns Vec<Option<String>>. That is what
Composer actually does: Preg::isMatch() always sets
PREG_UNMATCHED_AS_NULL, and its callers test groups with `!== null`.
preg_match_all(), preg_match_all_set_order() and
preg_split_delim_capture() still hand back Vec<String> and keep the ""
form.

The five IndexMap shapes that the preg_* functions and Preg fill in are
now distinct types generated by preg_match_map!, so a matches map no
longer interchanges with any other map of the same key and value type.
Index<usize> is kept alongside Index<&Q> because call sites such as
config_command and event_dispatcher reach for a group by its position in
the map rather than by its capture key.

The alternation that stands in for the original conditional subpattern
reports the branch it did not take as an empty string, so `dvar` was
always present and won over `pvar`, leaving %VAR% unexpanded. `\w+`
cannot capture an empty string, so an empty branch means it did not
participate.

The PHP splits with PREG_SPLIT_NO_EMPTY, but the port dropped that flag,
so a leading separator in NO_PROXY kept an empty first entry. That made
"empty($hostNames) || '*' === $hostNames[0]" false for values such as
" *", turning "bypass the proxy for every host" into "use the proxy
for every host".

preg_split2()'s limit was always -1 and its flags were always either 0 or
PREG_SPLIT_DELIM_CAPTURE alone, so both arguments are gone: the shim now
exposes preg_split() and preg_split_delim_capture() over a shared
preg_split_impl(). That leaves Preg::split()/split4() as bare
pass-throughs, so callers use the shim functions directly and the wrappers
are dropped along with the now-unreferenced PREG_SPLIT_* constants.

* CurlDownloader::handle_redirect tested scheme and host with is_null(), so
an unparsable Location header (PhpMixed::Bool(false)) counted as an
absolute URL. PHP's truthiness test sends it to the relative-path branch.
* Url::get_origin appended a literal port 0, which PHP treats as falsy and
leaves off.

Porting mapped every PHP `protected` member onto `pub(crate)`, which is

Split date() into date_utc() and date_local(), the latter resolving the
system's local timezone through the tzfile crate ($TZ, then
/etc/localtime, falling back to UTC when neither is readable). The
timestamps Composer renders for humans -- the GitHub OAuth token note,
the GitHub API rate limit reset time, the Perforce client spec fields and
the "today" check of the show command -- now go through date_local().
PHP resolves its default timezone from the date.timezone ini setting,
which Shirabe does not read, so date_default_timezone_get/set have no
input left to model and are dropped from the shim and its callers. The
resulting difference is recorded in docs/known-incompatibilities.md.

PhpDirHandle recorded the opened path and nothing else, and its only

that call directly.

The binary called itself Composer everywhere: the application name, the
logo, --version, about, and every warning that talks about the running
program. Prompts to file a bug also pointed at Composer's issue tracker.
Add SHIRABE_VERSION and SHIRABE_RELEASE_DATE next to the Composer version
constants and report those, naming the Composer version this port tracks
alongside them. Composer::VERSION and getVersion() are untouched, so the
composer platform package, composer-runtime-api and the HTTP User-Agent
keep the value plugins and package repositories expect.
build.rs stamps the release date with the UTC date of the HEAD commit,
the way Composer's Compiler fills in @release_date@ when building the
phar. It now also fails the build when git cannot be read, instead of
letting COMPOSER_DEV_WARNING_TIME fall back to the tagged-release value
and suppress the outdated-build warning forever.
Messages about the Composer ecosystem keep their wording. Two of them are
pinned by upstream installer fixtures (Rule's "cannot be modified by
Composer" and SolverProblemsException's "you can run Composer with") and
stay as they are so those fixtures can keep being used verbatim.
The e2e list comparison against upstream Composer now skips the banner,
which cannot match by design, and compares everything below it as before.

The shim reported a fixed PHP 8.1.0 through PHP_VERSION, PHP_VERSION_ID,
the major/minor/release triple and the PHP_WINDOWS_VERSION_* trio. Their
uses split in two.
Some guarded branches PHP only needs on runtimes this port cannot be:
proc_get_status reports the exit status on every call, so Symfony's
pre-8.3 exit-code cache has nothing to work around; hash_raw and
hash_file always offer xxh3, so the sha1 fallback is unreachable; and
http_get_last_response_headers is always available, so the pre-8.4
$http_response_header branch is gone. safeJunctions reads the host
Windows version rather than PHP state, and joins the Windows work on
hold.
The rest ask about the PHP the user actually runs, and now reach the
worker through a new php-rpc PhpVersion payload: the startup banner and
the 7.2.5 warning, self-update's min-php filter, the ext-*
recommendation in VersionSelector, the stream User-Agent, and whether
PhpFileParser scans for enums.

`http_build_query` ignores `numeric_prefix` because a string-keyed slice never
holds an integer key, and every caller passes `"&"` as the separator. Drop both
parameters and hard-code the separator.
Callers that pass a map of scalar literals to `http_build_query_mixed` no longer
need to build an `IndexMap<String, PhpMixed>` for it, so move them to the slice
form.

The constant was None and defined("HHVM_VERSION") reports it undefined, so
every branch guarded by it was dead: shirabe is a Rust binary and never runs
on HHVM. HhvmDetector keeps probing for an `hhvm` binary in PATH, which is
what actually produces the hhvm platform package.
Two of the dropped branches ask about the PHP runtime that consumes the
result rather than about shirabe itself -- the class loader's Hack file
lookup and the class map parser's enum scanning -- so both get a
TODO(php-runtime) marker.

The SignalHandler port was a no-op stub, so all four of Composer's abort
paths were dead code: nothing removed a half-created project, reverted
composer.json, or cleaned up half-installed packages.
Composer runs those handlers from pcntl callbacks, which a Rust signal
handler cannot do -- it may touch nothing beyond atomics. SignalSubscription
records the signal instead, and the abort runs from checkpoints on the normal
call stack, where the clean-up can borrow the state it needs. That also
resolves the closure-capture TODO(phase-c)s in RequireCommand and
InstallationManager, and replaces exit_with_last_signal's exit(0) with the
restore-and-re-raise Seld\Signal does.
A subscription is live only inside the four abort regions, so elsewhere the
signals keep their default disposition and kill the process at once. It is
installed without SA_RESTART so a signal interrupts an interactive prompt
rather than resuming the read. A signal reaches only the innermost
subscription, reproducing SignalHandler's single-stack dispatch.
Drop SignalRegistry, SignalableCommandInterface and the Application wiring
for them: nothing in Composer reaches that path, and SignalHandler discards
whatever they register. Signal handling from plugins and scripts is
undefined behavior; see docs/dev/signals.md.

Composer's Composer\Util\TlsHelper is marked deprecated for removal in
Composer 3.0 and has no caller in composer/composer outside its own
test: PHP's stream layer verifies certificate hostnames itself, and the
one surviving method delegates to composer/ca-bundle.
The Rust port had no caller either, so it, its test, and the
openssl_x509_parse shim it was the sole user of are removed.

Composer restarts itself with Xdebug unloaded because Xdebug makes PHP
several times slower. Xdebug is never loaded into this process, so what
needs dealing with is the PHP worker: it is spawned with
`-d xdebug.mode=off` and `XDEBUG_MODE=off` (Xdebug reads the environment
variable first and lets it override every ini setting), which makes its
module init return before it installs any executor, compile, error or
opcode hook.
Rewriting the ini files and re-executing, the way xdebug-handler does,
would additionally cover Xdebug 2, which hooks unconditionally and has no
equivalent setting. That is not worth its machinery here: Xdebug 2 caps
out at PHP 7.4, while every PHP version Composer supports can run
Xdebug 3.
What remains of XdebugHandler is small enough to live beside the worker
it governs, so its crate is gone and its callers inline it. isXdebugActive
answers false without asking PHP whenever the worker is switched off, so a
command that needs no PHP does not spawn one just for the Xdebug warning;
diagnose reports what the worker measures instead, which still surfaces an
Xdebug that ignores the setting. PlatformRepository has no unloaded
extension to restore, since switching the mode off leaves it loaded.
COMPOSER_ORIGINAL_INIS is neither written nor read: it exists so a
restarted process can name the ini files it replaced, and IniHelper can
report the worker's own. IniHelperTest injects through that variable, so
none of its cases are ported.

doRemove() renames a directory to a random hidden name before emptying
it, and undoes that rename when the final rmdir fails, so a concurrent
process cannot recreate the path mid-removal. It also walks one level at
a time through FilesystemIterator instead of flattening the whole tree,
and lets an inner rmdir failure pass, both as upstream does.
copy() keeps the mode fopen($targetFile, 'w') would have left rather
than the origin's, symlink() and mirror() call readlink() and
getLinkTarget() where upstream does, and a directory iterator that
cannot be opened propagates its UnexpectedValueException instead of
being swallowed or flattened into an IOException.
Error message text is out of scope per docs/known-incompatibilities.md,
so the three TODO(phase-c) markers that only tracked wording are gone,
along with linkException()'s Windows-only branch. So are the arguments
no caller varies -- symlink()'s copyOnWindows, mirror()'s iterator and
options, copy()'s overwriteNewerFiles -- which removes the last
TODO(phase-c) in the file.
New shim functions: readlink, filesystem_iterator, stream_is_local,
strrev and SplFileInfo::getLinkTarget. base64_encode takes bytes so
random_bytes() can feed it.

shirabe-xdebug-handler crate
Move `Composer\XdebugHandler` out of shirabe-external-packages and into
its own crate, so the path is `shirabe_xdebug_handler::XdebugHandler`
instead of
`shirabe_external_packages::composer::xdebug_handler::XdebugHandler`.
Standing alone, the stub no longer sits in a crate that shirabe-php-rpc
depends on, so drop the dependency-cycle rationale from the comments that
explain why callers reach for shirabe_php_rpc directly.

shirabe-symfony-console crate
Move `Symfony\Component\Console` out of shirabe-external-packages and
into its own crate, so the path is
`shirabe_symfony_console::application::Application` instead of
