Gate the SDK version request on update checks.
NucleiSDKVersionCheck runs before CanCheckForUpdates. The SDK sends a version-check request even when updates are disabled. Move this call inside the update-check branch.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Create the active ignore file for non-CI runs.
When suite.ci is false, prepareFunctionalEnvironment does not run, but this new NUCLEI_TEMPLATES_DIR points functional tests to a fresh directory without .nuclei-ignore. config.LoadIgnoreFile() requires that active file during initialization, so local functional runs fail before tests execute.
Create a valid file such as tags: [] under the active templates directory before m.Run(), or perform equivalent setup for non-CI runs.

Load XDG system configuration (and /etc/nuclei/config.yaml) before the active user configuration, selected config, profile, and command line. Preserve explicit command-line values, replace collections between layers, and defer stateful option handling until the final values are known. Keep callback flags and authentication setup limited to the CLI. Move configuration loading, profile resolution, inline targets, and inline secrets into internal/configuration. Keep NUCLEI_CONFIG_DIR as a compatibility override for the user configuration directory. Use platform directories for configuration, template data, persistent state, and cache data. Discover default template roots through XDG_DATA_HOME and XDG_DATA_DIRS without assigning ownership semantics to the selected path. Store template state in XDG_STATE_HOME and migrate the legacy .templates-config.json file when needed. Persist the active template path, keep custom provider templates below that root, and apply the same installation, update, health-check, and reset behavior to every root. Keep .nuclei-ignore with the active template root and fail when the file is missing or invalid. Derive its local hash from the file and pass the remote hash through the update check without persisting either value. Move generated resume and crash-recovery files into persistent state and use XDG_CACHE_HOME for the catalog index. Write template state and cache snapshots atomically with private permissions. Validate every reset target before deleting any path. Reject broad or unsafe targets, preserve explicit resume paths, and remove generated inline-secret directories on normal, interrupted, and fatal exits. Isolate configuration, state, cache, and template paths in functional and integration tests, and add coverage for layered precedence, state migration, active-root lifecycle, reset safety, and private file modes.

Integration tests fail on linux, mac, and windows.
The suite sets NUCLEI_TEMPLATES_DIR to $HOME/nuclei-templates, always passes -duc, and never writes .nuclei-ignore. LoadIgnoreFile is now mandatory, while install/update only run when update checks are enabled, so startup exits 1 before any scan.
Treat a missing ignore file as warn + empty denylist (or seed tags: []). Keep failing on a corrupt file. Point the test template root at the temp dir and seed that file there.
Also: gate NucleiSDKVersionCheck on CanCheckForUpdates, and do not call f.Name() after a failed os.Create.

Proposed changes
Closes #6755
Layered configuration
Config now loads bottom-up:
CLI wins, including when you pass a value that happens to be the
default. Layers replace maps/lists; they do not merge-append. System
files that aren't there are fine. A broken auto-loaded layer warns.
-config/-profileflags that fail still abort.A selected config or profile cannot send you back to an earlier stage.
YAML cannot run callback flags. Update-style state is applied after
the stack is finished.
-authstays CLI-only.NUCLEI_CONFIG_DIRis unchanged: it still is the user config dir(not an extra overlay). You can drop a copied or generated
config.yamlthere. But signing keys and reporting config still liveunder it. [I think we should not do that.]
Profiles
Resolve by filesystem path or community profile ID against the final
template root. Inline targets get the same normalization as everywhere
else. Inline secrets go into a private temp dir and get deleted on
normal exit, interrupt, and fatal paths.
XDG layout
$XDG_CONFIG_HOME/nuclei$XDG_DATA_HOME/nucleiand$XDG_DATA_DIRS/nuclei$XDG_STATE_HOME/nuclei$XDG_CACHE_HOME/nucleiGenerated resume / crash-recovery files go under state (previously
config and cache (#6792), lol). An explicit
-resumepath is leftalone. Health / diagnostics print the state dir as its own thing.
Templates and state
Default template root, in order:
$XDG_DATA_HOME/nuclei/nuclei-templatesif it already exists$XDG_DATA_DIRS/nuclei/nuclei-templatesState moved from
$XDG_CONFIG_HOME/.templates-config.jsonto$XDG_STATE_HOME/templates.json. Writes are atomic, mode0600. Ifthe new file is missing we copy over the old one and leave the old
file sitting there.
The new file only keeps the active path plus version bits. Old
template-source / ignore-hash fields are read and then dropped on
rewrite.
FYI custom GitHub / GitLab / S3 / Azure template dirs still hang off
the active root.
.nuclei-ignoreOnly the active template root is consulted (the sole source).
Missing or garbage ignore file fails both CLI and SDK. We no longer
copy a leftover ignore file from the config dir into a template tree.
Managed nuclei-templates install/update writes
.nuclei-ignoreatomically into that root. Local hash is of that file. Remote hash is
only passed through from the version check - AND is not stored.
Old fields/methods are still on the SDK as no-op compatibility shells.
Cache and other files
Catalog index:
$XDG_CACHE_HOME/nuclei(was.nuclei-cache). Newcache dirs
0700. Snapshots0600, replaced atomically.Template state uses the same write helper. Resume serialization now
includes the operation + path when encode / mkdir / write blows up.
-resetand health-resetresolves the final paths first. Every target is checkedbefore anything is deleted. Empty paths,
/,$HOME, temp, cwd,overly broad trees, and unsafe symlink resolutions are refused.
Reset deletes config, state, cache, and the active template root the
same way.
Health looks at config init,
templates.json, the active.nuclei-ignore, checksums, plus the usual connectivity probes. Everyactive root gets the same r/w checks.
CLI / SDK
Startup now surfaces template-state init failures. Ignore loading on
the active root is strict.
NucleiVersionCheck/NucleiSDKVersionCheckreturn the transientremote ignore hash alongside the error. That changes the exported
pkg/installersignatures but does not change the officiallibAPI.Why this goes beyond #6755
#6755 proposes a cascading configuration hierarchy so distro defaults
in
/etc/nuclei/config.yamlcan sit under user config and CLI. That'sin.
Two things the issue left hanging, we picked:
NUCLEI_CONFIG_DIRstays the user-dir override; no second env var-configand-profileare just extra layers. Per-flag CLI valuesstill sit on top.
The rest of this PR is because once
/etccan point templatessomewhere that isn't
$HOME/nuclei-templates, install, ignore files,metadata, health, reset, and version check were all still assuming the
old layout. They now share one active root.
XDG split is extra relative to the issue: state + generated resumes
under
XDG_STATE_HOME, catalog underXDG_CACHE_HOME, templatesunder data home/dirs. Existing installs keep their selected path or
version via the one-shot migrate.
While we were moving paths: private perms + atomic writes, reset
refuses to rm until every target looks sane, missing ignore fails
closed, profile secret temps get wiped on fatal/interrupt. Callbacks
and auth stay off YAML so a packaged config can't start updates or
similar as a side effect.
tl:dr; #6755 defines the configuration hierarchy. This makes the rest
of Nuclei use the paths that stack produces, moves old state, and
stops the "we can now point at new dirs but still write junk next to
config" class of bugs.
