New services/navi_config/ on :8422, mirroring recon's /api/config contract:
- config_route.py: GET /api/config -> jsonify(get_deployment_config())
with Cache-Control: public, max-age=300 (byte-for-byte recon's response).
- config_loader.py: faithful port of recon lib/deployment_config.py. Reads
RECON_PROFILE (default "home") and NAVI_CONFIG_PROFILES_DIR (default
/opt/recon/config/profiles, so it serves the SAME files recon does during
cutover). yaml.safe_load, module-level cache. Lazy load (vs recon's eager
import-time load) so the module imports cleanly off-VM and a missing
profile surfaces as HTTP 500 at request time rather than a failed import.
- admin.py: /api/admin/navi-config/info per handoff §4.5, require_auth gated.
env values (NAVI_CONFIG_PROFILES_DIR, RECON_PROFILE) are non-secret paths/
names, shown as-is (no mask_key); dependencies=[]; filesystem reports the
active profile path + exists/readable.
- app.py: create_app() factory mirroring navi_traffic, same metrics wiring;
resets the loader cache per instance so each worker/test reloads fresh.
Deploy artifacts: systemd unit (:8422) and an nginx snippet using
`location ^~ /api/config` (the ^~ convention from extraction #1 so the asset
.png/.css regex can't shadow it). No proxy_cache zone — the response is
already cached in-process and via Cache-Control: max-age=300; emits a literal
X-Cache-Status: BYPASS for parity with navi-traffic.
Adds PyYAML>=6 to deps. Tests (services/navi_config/tests): 200 + parsed dict,
Cache-Control header, RECON_PROFILE override, default=home, missing profile=500.

navi-backend
Monorepo of small, single-responsibility HTTP services extracted from the recon
codebase as part of the recon ↔ Navi decoupling project. Each service owns a
slice of the /api/* surface that navi.echo6.co depends on, runs behind the
existing Caddy/Authentik edge, and is fronted by the navi.echo6.co nginx vhost.
See HANDOFF-recon-navi-decoupling-v3.md for the full plan. This repo is
extraction #1: navi-traffic.

Service directories use an underscore (navi_traffic) so they're importable
Python packages; the service name stays navi-traffic (hyphen) in systemd,
nginx, and the admin-info service field.
Setup
Single workspace, single virtualenv:
python -m venv .venv
.venv/bin/pip install -e .
Test
.venv/bin/pytest services/navi_traffic/tests/ -v
Run (local)
TOMTOM_API_KEY=... .venv/bin/gunicorn 'services.navi_traffic.app:create_app()' \
--bind 127.0.0.1:8421 --workers 2
The admin-info convention (§4.5)
Every service exposes GET /api/admin/<service-name>/info, gated by require_auth,
returning a uniform shape: service, version (git SHA), port, config, env
(names + masked values), dependencies (upstream health checks), filesystem,
runtime (uptime / request count / last error). No aggregator — a future admin
panel fans out to each service in parallel.
