Does each composer patch still apply to the release the site installed, and is its fix already in that release?

Send composer_json and composer_lock after composer update. Add patch_files for every patch, a local one read from disk and a URL one fetched by you. Every extra.patches entry is checked at its installed version in one call.
Do not download releases. Do not run patch --dry-run.
Send a package's patches together, in the order composer.json lists them.
items: up to 50 of {project, version, patch, title}, in place of the composer files. project: the drupal.org machine name (webform) or composer name (drupal/webform); drupal or core for Drupal core. version: the installed composer version (1.13.0, 2.0.0-beta4, 11.4.5). patch: the diff text, or its URL on www.drupal.org/files/issues or a git.drupalcode.org merge request or commit, ending .patch or .diff.
Per item. tag: the release tag matched, or unknown_version. applies_at: the -p level at which git apply passes, null when none. fuzzy: true when it applied only with reduced context and whitespace ignored; review it. hunks_failed: [{file, line, reason}]. reverse_applies: true when the patched lines are already in the tag. mr: the merge request state when the patch is an MR URL. merged_in_version. suggested. failure_mode: set when a patch applies and a file it touches no longer parses; keep the patch and fix the file. syntax_errors: the files behind it, one per file, path then the parser's message.
suggested: the verdict. merged: the fix is in the release; drop the patch. applies: keep the patch. conflicts: call reroll_patch with that item. unknown: see error.
next_step: the follow-up calls and the row count the report must have. counts: the verdict tally; check the report's table against it. An item that could not be judged comes back unknown with the reason in error. Report it as unclear. Never leave the row out.
hunks_shipped, files_shipped: the parts of a patch already in the release verbatim. On a conflicts row, check whether the rest is still needed before re-rolling. moved_to: on a failed hunk, the release path of the renamed file.
core_references: what the added code references in core, checked at target_core. flagged: removed or moved classes, and calls whose argument count does not fit the target signature, each with file, line, change_record and replacement. parent::__construct is checked against the constructor of the core parent class. deprecated: a short side list. checked: how many references the catalog knows. Scope: added lines and direct references only (extends, implements, trait use, new, static calls, parent::__construct). A patch that does not apply has a note instead.
Verdicts come from git apply --check against the tag. An applies patch can still be wrong at runtime.

Input schema

Property	Type	Required	Description
items	null \| array	no	Up to 50 patches to check. Each item has project, version, patch and title. project: webform or drupal/webform; drupal or core for Drupal core. version: the installed composer version, 1.13.0 or 11.4.5. patch: the diff text. This service downloads nothing, so fetch a URL patch yourself and send what came back. source: optional, the path or URL the patch was declared with. merge_patch: optional, the .diff form of a merge request, used for the merge of a re-roll while patch decides the verdict. provenance: optional, where a copied patch's bytes came from, {mr, commit, url, base, head, fetched, rerolled}. Send it when source is a local path. title: optional, echoed back. base: optional, the release the site had before the upgrade. A commit sha or a composer version, tried first as the merge base of a re-roll. Leave empty to build the items from composer_json and composer_lock.
composer_json	string	no	The contents of composer.json. Send the text; this server cannot read your filesystem. Its extra.patches becomes the item list, one item per patch.
composer_lock	string	no	The contents of composer.lock. It gives the installed version of each patched package.
patches_file	string	no	The text of the patches file, for a site on cweagans/composer-patches 2.x that keeps its patches out of composer.json. The path is in its own extra.composer-patches.patches-file, patches.json by default.
patches_lock	string	no	The text of patches.lock.json, which 2.x of the patch manager writes and applies from. Send it to judge what the site actually applies: it answers alone, over extra.patches and the patches file.
patch_files	object	no	The text of every patch the site declares, keyed by the source as written: a path (patches/x.patch) or its base name, or the URL. Fetch a URL patch yourself and send its text under that URL. For a merge request .patch URL, send its .diff form under a second key too.
target_core	string	no	Core the added code is checked against: a minor (11.4 or 11.4.x) or a release (11.4.5). A minor with no core release in the data is refused, and so is a major alone. latest checks no references. Defaults to the lock's drupal/core, else the version of a drupal item.
