Background
==========
PR #285 set up the seed -> cache -> GDELT model for the carrier tracker
to address audit issues #244/#245/#246. The GDELT half of that pipeline
hits api.gdeltproject.org's doc API for headline-region keyword
matching -- low precision (false centroid positions per #245) AND
unreliable (the host times out from some networks, including Docker
Desktop on Windows).
USNI publishes a weekly Fleet & Marine Tracker with explicit prose like:
"The Gerald R. Ford Carrier Strike Group is operating in the Red Sea"
"Aircraft carrier USS George Washington (CVN-73) is in port in
Yokosuka, Japan"
That is a strictly better source for U.S. Navy carrier positions:
authoritative, deterministically parseable, weekly cadence.
What this PR does
=================
New module: backend/services/fetchers/usni_fleet_tracker.py
- Pulls USNI's WordPress RSS feeds (site-wide + category, unioned).
- Picks the most recent fleet-tracker post by parsed pubDate.
- For each carrier in the registry, scans the article body for
"is operating in / is in port in / returned to / transiting" near
the carrier's name, hull code, or "<name> Carrier Strike Group"
variant. Captures the region/port phrase that follows.
- Maps the region phrase to coordinates via the existing
REGION_COORDS table, with a USNI-phrase alias table for the
specific wording USNI uses ("Yokosuka, Japan", "Norfolk, Va.",
"Naval Station San Diego", "5th Fleet AOR", etc.).
- Returns {hull: position_entry} with position_confidence="recent"
and position_source_at = the article's actual publication
timestamp (not now()).
Politeness
----------
Uses outbound_user_agent("usni-fleet-tracker") so USNI sees a
per-install Shadowbroker identifier (Round 7a / PR #292). The
article body pages return 403 to non-browser UAs; the WordPress RSS
feed serves the full <content:encoded> body and is the supported
aggregator path. No browser UA spoofing.
carrier_tracker.update_carrier_positions() now runs three phases:
1. Bootstrap from cache (or seed on first run).
2. USNI fleet tracker -- PRIMARY high-confidence source.
3. GDELT -- SECONDARY backfill; can NOT demote a "recent" USNI
position to an "approximate" GDELT headline match.
Verified live: 6 of 11 carriers picked up real May 18, 2026 positions
on first refresh (Eisenhower, Ford, Bush, Roosevelt, Lincoln,
Washington). The other 5 weren't mentioned in this week's article
(they're in port at homeports with no deployment changes) and kept
their cache entries -- which is the correct seed/cache contract from
PR #285.
Other small fixes bundled in
============================
docker-compose.yml: add the 6 third-party-fetcher opt-in env vars
(PREDICTION_MARKETS_ENABLED, FINANCIAL_ENABLED, FIMI_ENABLED,
NUFORC_ENABLED, NEWS_ENABLED, CROWDTHREAT_ENABLED). They were
documented in .env.example but never wired through compose, so setting
them in .env had no effect.
frontend/src/components/TopRightControls.tsx: fix 6 broken i18n keys
that were showing as raw "terminal.term1" / "terminal.cleanupDetail" /
"node.soloReady" placeholders in the INFONET TERMINAL modal. The
translation files have these strings under different key names; the
component now calls the right ones. Full-file sweep confirmed every
other t('...') key in the whole frontend resolves cleanly.
