+# CI Multilingual Audit
+
+## Purpose
+The multilingual audit verifies that public content stays locale-correct across all active MandelBlog languages after deploy.
+
+It checks rendered, user-facing text for:
+- mixed-language fragments
+- foreign UI labels
+- weak or generic badge labels flagged by policy
+- locale-specific normalization problems
+
+It does not modify content in CI. It only audits and reports.
+
+## Jenkins jobs
+
+### Main pipeline: `mandelstudio`
+The main pipeline runs a post-deploy multilingual audit after staging deployment completes.
+
+Stages relevant to multilingual quality:
+1. `Deploy Staging`
+2. `Post-Deploy Multilingual Audit`
+
+The audit stage runs remotely on staging:
+```bash
+python manage.py audit_locales --format=json
+```
+
+Artifact archived:
+- `artifacts/multilingual-audit.json`
+
+### Nightly pipeline
+Pipeline source:
+- `Jenkinsfile.multilingual-nightly`
+
+Schedule:
+- `H 2 * * *`
+
+The nightly job:
+- runs the full multilingual audit on staging
+- archives the latest JSON artifact
+- compares the current artifact against the previous artifact
+- prints regressions by locale
+
+## Build result policy
+The audit summary is interpreted as follows:
+
+- `SUCCESS`
+  - all locales have `block=0` and `warn=0`
+- `UNSTABLE`
+  - at least one locale has `warn > 0`
+  - deploy is not blocked
+- `FAILED`
+  - at least one locale has `block > 0`
+  - or audit execution itself fails
+
+This keeps deploys safe without making warning-level cleanup a hard blocker.
+
+## Required Jenkins credential
+Credential location:
+- `Manage Jenkins -> Credentials -> System -> Global credentials`
+
+Credential to add:
+- `Kind`: `SSH Username with private key`
+- `ID`: `staging-root-ssh`
+- `Username`: `root`
+- `Private key`: staging SSH key
+
+Current implementation uses the following environment defaults:
+- `STAGING_AUDIT_HOST=root@49.12.204.96`
+- `STAGING_AUDIT_PROJECT_DIR=/home/www-mandelstudio/mandelstudio`
+- `STAGING_AUDIT_MANAGE=/var/lib/virtualenv/mandelstudio/bin/manage.py`
+
+## Console summary
+The Jenkins stage prints a per-locale summary like this:
+```text
+LOCALE en: issues_found=0 issues_remaining=0 block=0 warn=0 log=0
+```
+
+Nightly runs also print regressions when present:
+```text
+REGRESSIONS:
+- es: remaining=+2 block=+0 warn=+2 log=+0
+```
+
+If no regressions exist:
+```text
+REGRESSIONS: none
+```
+
+## Artifact structure
+Archived file:
+- `artifacts/multilingual-audit.json`
+
+Expected clean structure:
+- `run_id`
+- `total_urls_checked`
+- `issues_found`
+- `summary`
+- `issues`
+
+Failure artifacts may also contain:
+- `error`
+
+This happens when the remote audit times out or fails, and is intentional so Jenkins still archives a machine-readable result.
+
+## Local rerun
+To rerun the same remote audit flow locally:
+```bash
+export STAGING_AUDIT_HOST='root@49.12.204.96'
+export STAGING_AUDIT_PROJECT_DIR='/home/www-mandelstudio/mandelstudio'
+export STAGING_AUDIT_MANAGE='/var/lib/virtualenv/mandelstudio/bin/manage.py'
+./scripts/run_remote_multilingual_audit.sh
+python3 scripts/multilingual_audit_ci.py --json artifacts/multilingual-audit.json
+```
+
+To compare against a previous artifact:
+```bash
+python3 scripts/multilingual_audit_ci.py \
+  --json artifacts/multilingual-audit.json \
+  --previous-json artifacts/previous-multilingual-audit.json
+```
+
+## Fixing issues by locale
+Recommended response sequence for any locale that returns warnings or blocks:
+1. run scoped dry-run audit for the affected locale/pages
+2. inspect before/after rewrite candidates
+3. apply controlled rewrite only to affected pages
+4. rerun post-audit
+5. manually verify rendered output
+
+Do not bulk rewrite a locale tree without scoped review first.
+
+## Operational notes
+- remote audit execution has a timeout
+- audit failure still produces JSON output for Jenkins archiving
+- missing previous nightly artifact is handled gracefully
+
+## Hardening candidates
+These are operational follow-ups only. They are not required for current behavior.
+- replace `root` SSH with a dedicated deploy/audit user
+- move host/path configuration into Jenkins-managed environment variables or folder-level config
+- document SSH credential rotation procedure

docs/DEVPI_RELEASE_FLOW.md

@@ -0,0 +1,68 @@
+## Devpi Release Flow
+
+### Current state
+
+- `mandel/testing` is the active package source for MandelBlog project builds.
+- `ocyan.plugin.template_engine==0.2.12` is published there and is the current production-safe version.
+- `mandel/stable` is not available yet.
+
+This means production is intentionally running from the testing index for now, to avoid breaking installs while the stable index is not provisioned.
+
+### Index roles
+
+- `mandel/testing`
+  - pre-production and current fallback source
+  - currently also the active production source until stable exists
+- `mandel/stable`
+  - intended production index
+  - not yet provisioned
+
+### Promotion flow
+
+When `mandel/stable` exists, promote existing artifacts without rebuilding:
+
+```bash
+devpi use https://pypi.mandelblog.com/mandel/testing
+devpi login mandel
+devpi push ocyan-plugin-template-engine==0.2.12 mandel/stable
+```
+
+### Admin prerequisite
+
+Promotion requires a devpi admin to create the production index and grant upload or push permissions.
+
+Recommended admin setup:
+
+```bash
+devpi index -c mandel/stable bases=root/pypi volatile=False acl_upload=mandel,Mandel-publish
+```
+
+### Planned stable-first install order
+
+Do not enable this until `mandel/stable` exists:
+
+```bash
+PIP_INDEX_URL=https://pypi.mandelblog.com/mandel/stable/+simple/
+PIP_EXTRA_INDEX_URL=https://pypi.mandelblog.com/mandel/testing/+simple/
+```
+
+### CI behavior
+
+- If the stable index is missing, Jenkins logs:
+  - `devpi stable index not available, using testing as production source`
+- The build does not fail because of the missing stable index.
+- Installs continue from `mandel/testing`.
+
+### Validation checklist
+
+After stable becomes available and promotion is done:
+
+1. confirm both wheel and sdist are visible in the stable simple index
+2. switch MandelStudio to stable-first
+3. run Jenkins build and deploy
+4. verify installed version is still `0.2.12`
+5. recheck editor validation for:
+   - `/contact/`
+   - `/diensten/`
+   - `#demo`
+   - absolute URLs
