Build the archlinexp.eu/www baseline from clean sources on a dedicated
site branch, per the web-baseline deploy model: vanilla Joomla 3.9.2 core
plus the developer-sourced own-code plus a vetted module layer, with the
Cadline core delta applied on the 3.9.2 base. The generator is reused
unchanged: build-baseline.sh is site-agnostic, only the content differs.
Layers:
- core/ vanilla Joomla 3.9.2 official package (installer removed)
- cadline/ own-code from the developer source (beiratkozas, maintenance,
mod_al_*, mod_alusers, mod_course_list) plus 11 assets that
the developer source lacks
- deployed/ 95 third-party module slugs taken from live, YARA-vetted
- overrides/ the 5 genuine Cadline core modifications, on the 3.9.2 base
The live core carried 31 stale com_users files: the updater skipped the
customized ones, so the version string said 3.9.2 while the code did not.
Taking vanilla 3.9.2 plus the 2 real deltas fixes that silently. 289
planted paths are excluded through malware-iocs.paths.
Verification: build-baseline.sh -> out/ = 12286 files; YARA (16 rules) on
every source layer and on the built tree = 0 hits; not one IOC path
present; no disguised .json dropper; core verified as 3.9.2.

The developer-controlled Cadline repos (cadcommonlib, maintenance) become git
submodules so updates flow through: git submodule update --remote -> build ->
commit new pointers. Pinned to their authoritative HEADs. build-baseline.sh
inits the submodules and normalizes their CRLF to LF (the deploy transform) so
the assembled baseline byte-matches the deployed form. constants.php (live-only
config, not in the repo; carries a DB credential tracked in the credential
inventory) is kept as an overlay (overrides/) per instruction — removal happens
at source later.

beez3 css/js/language + system modal.php/template.php present on live but absent from the downloaded package build; clean core template files.

The ~24 legit Cadline customizations on the Joomla core (audit sec.16.1):
reCAPTCHA anti-spam (registration/reset/remind/login flow, captcha rule),
content view tweaks, mod_login template, phpversioncheck. build-baseline.sh
overlays these live versions onto the official-package core so the baseline
matches live for the legit mods, while the 3 trojanized core files stay clean.
NOTE: com_users/controllers/registration.php carries a hardcoded reCAPTCHA
secret (redacted; rotate on cleanup) — see malware-iocs.md.

Re-architect the baseline as constituents + a generator script (build-baseline.sh)
instead of a checked-out deployed tree: a deployed Joomla docroot differs from the
repo/source layout, so the script manifest-maps packaged extensions (lib/jmap.py),
places no-source and Cadline files, applies core overrides, excludes malware/data,
and emits out/ = the code baseline the operator HIDS verifier consumes.
Adds RUNBOOK.md (recipe+inventory), PROVENANCE.md (upstream map), malware-iocs.
