Matt Johnson bba59e9f17 Add navi-contacts service (extraction #3)
New services/navi_contacts/ on :8423 — two blueprints, behavior-identical
ports of recon's contacts + address_book code.

Routes:
  contacts (10, all @require_auth, per-user via X-Authentik-Username):
    GET/POST /api/contacts; GET /api/contacts/nearby; GET /api/contacts/deleted;
    GET/PATCH/DELETE /api/contacts/<id>;
    POST /api/contacts/<id>/restore; POST /api/contacts/<id>/restore-as;
    DELETE /api/contacts/<id>/purge
  address_book (2, public):
    GET /api/address_book/lookup?q= ; GET /api/address_book/list

Data ownership (per Matt's rule — DBs live in navi-backend territory,
auto-create on first run; only massive tilesets stay external):
  - contacts.db: env NAVI_CONTACTS_DB (default /var/lib/navi-backend/contacts.db).
    ContactsDB auto-creates the schema (table + 5 indexes incl. the partial-
    unique Home/Work index) on first open via CREATE ... IF NOT EXISTS — this
    is recon's own behavior, ported verbatim. WAL + busy_timeout=5000 preserved.
  - address_book.yaml: vendored into config/address_book.yaml (read-only, like
    the deployment profiles in extraction #2); path via NAVI_ADDRESS_BOOK_YAML.

Tests (28 new; recon had none for contacts): full ContactsDB CRUD, soft-delete/
restore/restore-as/purge, Home/Work 409 (create + restore conflict), nearby
proximity, search/category filter, per-user partitioning, auth-required, and
DB auto-create; plus address_book ported from recon's test (exact/partial/
case-insensitive/alias/miss/empty/list/hot-reload/missing-file). Full suite 38.

Timestamp fix (diverges from recon on purpose): restore_as builds updated_at
with Python's strftime. recon uses the bare '%Y-%m-%dT%H:%M:%fZ' there — but
Python's %f is microseconds-only (no seconds), so that yields malformed ISO
strings like "...T15:30:123456Z". recon's own update()/soft_delete() use the
correct '%Y-%m-%dT%H:%M:%S.%fZ'. This port uses the correct format in all three
places and adds a regression guard (strptime) in test_restore_as_relabels.
This is a PRE-EXISTING recon bug; we fix it here. The recon-side restore_as
retires with extraction #7 (Jinja /nav-i + /deleted-contacts removal), so the
recon refactor doesn't need to touch it.

Also: shared/auth.py require_auth now sets request.user_id (recon's contract —
the contacts routes read it). Backward-compatible: navi-traffic/navi-config
admin endpoints don't use it.

Deploy artifacts: systemd unit (:8423) + nginx snippet with two ^~ blocks.
NOTE the nginx prefixes are `^~ /api/contacts` and `^~ /api/address_book`
WITHOUT a trailing slash, so the bare `/api/contacts` (list/create) is matched
too — a trailing-slash prefix would miss it and fall through to recon.

See ../recon_refactor/extraction-3-phase-a.md for the route/schema/ownership
analysis (which also corrects the handoff: contacts is /opt/recon/data/
contacts.db, NOT /mnt/nav/navi.db).

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.
