feat(flights): stamp source attribution on every flight record

Pre-fix, adsb.lol records (the primary source for most flights) carried
no source marker. OpenSky records got is_opensky: True and supplementals
got supplemental_source, so any UI inspecting source labels saw
OpenSky/airplanes.live records as explicitly tagged and adsb.lol records
as "unlabeled" — making it look like adsb.lol wasn't being used at all
even though it's the primary source.

Changes:

* _fetch_adsb_lol_regions stamps source="adsb.lol" on each aircraft
  before returning, so the tag survives the OpenSky dedupe-by-hex merge.
* OpenSky records get source="OpenSky" (alongside is_opensky=True for
  back-compat).
* military fetcher tags source on both adsb.lol and airplanes.live
  records before they're merged, and propagates source into the
  military_flights and uavs output dicts.
* _classify_and_publish promotes the explicit source field into the
  published flight dict. Falls back to legacy supplemental_source if
  source is absent. Final fallback "adsb.lol" preserves prior behavior
  for any caller synthesizing records without going through a fetcher.

8 new tests cover the published-dict propagation, OpenSky tagging,
supplemental fallback, explicit-wins precedence, default behavior, the
adsb.lol regional fetcher tagging, and the military output dict.

+"""Rate-limit key function for slowapi.
+
+Issue #287 (tg12): the previous implementation used
+``slowapi.util.get_remote_address`` which only ever returns
+``request.client.host``. Behind the bundled Next.js proxy (or any other
+reverse proxy), every connected operator's ``client.host`` is the
+frontend container's bridge IP. ``@limiter.limit("120/minute")`` then
+collapses into one shared bucket for everybody on the same backend —
+one heavy tab can starve every other operator on the node.
+
+This module replaces that key function with one that:
+
+  * Reads ``X-Forwarded-For`` ONLY when the immediate peer is a trusted
+    frontend container (same allowlist used by the Docker bridge
+    local-operator trust path — see ``backend/auth.py`` ``#250``).
+  * Picks the FIRST entry in the XFF chain. That's the client end of
+    the proxy chain, which is the operator we want to bucket on.
+  * Falls back to ``request.client.host`` for any peer that isn't on
+    the trusted-frontend allowlist. Direct hits, unrelated containers,
+    and unknown hosts are bucketed exactly like before — there is no
+    way for an untrusted caller to spoof XFF and steal another
+    operator's rate-limit bucket.
+
+Single-operator nodes are unaffected: the frontend resolves to one IP,
+that IP is on the trust list, the XFF header is read, and you get one
+bucket per operator (i.e. you).

+# users, because:
+#
+#   * /api/sentinel/token  — caller supplies their own Sentinel client_id +
+#     client_secret. Without operator gating, the backend becomes a free
+#     anonymous OAuth-mint relay for any Copernicus account.
+#   * /api/sentinel/tile   — same shape as the token route but for tile
+#     imagery. Without gating, the backend acts as an anonymous quota and
+#     bandwidth relay for Sentinel Hub Process API calls.
+#   * /api/sentinel2/search — hits the Planetary Computer STAC search API
+#     and falls back to Esri imagery. No caller credentials are involved,
+#     but the route is still an anonymous external-search relay. We gate
+#     it the same way for consistency with the rest of the operator-only
+#     helper surface.
+#
+# Gating is via require_local_operator (loopback / bridge / admin key),
+# matching the same allowlist already used by /api/region-dossier and
+# the other operator helpers further up this file. Single-operator nodes
+# see no behavior change — their dashboard already lives on loopback or

+"""USNI News Fleet & Marine Tracker — authoritative weekly carrier
+position publication.
+
+Why this exists
+---------------
+The previous carrier_tracker pipeline relied on GDELT headline matching
+(``api.gdeltproject.org``) to derive positions from text like "USS Ford
+in the Mediterranean" → centroid of "Mediterranean Sea". That was
+- low-precision (audit issue #245 — false precision from text mentions),
+- unreliable (``api.gdeltproject.org`` is sometimes unreachable from
+  certain network paths, including Docker Desktop on some Windows hosts).
+
+USNI publishes a weekly tracker that explicitly lists where every U.S.
+carrier is operating. The article body uses extremely consistent phrasing:
+
+    "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."
+    "USS Dwight D. Eisenhower (CVN-69) sails down the Elizabeth River"
+
+Those are deterministic to parse. This module:
+
+  1. Pulls the WordPress RSS feeds (both site-wide and category) — the
+     site-wide feed often has fresher posts before the category feed
+     catches up, so we union them.
+  2. Picks the most recent post by parsed ``pubDate``.
+  3. For each carrier in the registry, scans the article body for a
+     "is operating in / is in port in / departed from" pattern near
+     the carrier's name.
+  4. Maps the extracted region phrase to coordinates via the carrier
+     tracker's existing REGION_COORDS.
+
+The result is a ``{hull: position_entry}`` dict that the carrier tracker
+consumes as a high-confidence source — ``position_confidence: "recent"``
+with ``position_source_at`` set to the article's actual publication
+timestamp (not ``now()``).
+
+Politeness
+----------
+We send the per-install operator handle via ``outbound_user_agent``
+(Round 7a) so USNI can rate-limit / contact the specific install if
+needed. Article-body pages return 403 to non-browser UAs (Cloudflare),
+but WordPress RSS feeds are open and serve the full article in
+``<content:encoded>`` — that's the supported path for aggregators and
+the one we use. We do not spoof browser headers.

+# Issues #289 / #290 / #291 and the retrofit of PR #284 (#218 / #219 / #220):
+# every third-party API the backend calls used to identify itself with a
+# single "Shadowbroker" aggregate User-Agent. From the upstream's
+# perspective, that meant every Shadowbroker install in the world looked
+# like one giant entity hammering them. If one install misbehaved, the
+# upstream's only recourse was to block "Shadowbroker" as a whole — which
+# would take out every other install too.
+#
+# Fix: give each install a stable pseudonymous handle and include it in
+# the User-Agent. Now an upstream can rate-limit or block the offending
+# operator without affecting anyone else.
+#
+# The handle:
+#
+# - Is auto-generated on first call if no `OPERATOR_HANDLE` is configured
+#   (looks like "operator-7f3a92" — 6 hex chars from uuid4()).
+# - Is persisted to ``backend/data/operator_handle.json`` so it survives
+#   restarts. Under Docker compose that file lives in the volume mount
+#   alongside `carrier_cache.json` and the other persistent state.
+# - Can be overridden by the operator via the `OPERATOR_HANDLE` setting
+#   (env var or settings UI). Operators with their own GitHub handle,
+#   organization name, etc. can use that for traceability.
+# - Is NEVER mixed into mesh / Wormhole / Infonet identity. This layer is

+"""Infonet sync respects upstream HTTP 429 + applies exponential backoff.
+
+Background
+----------
+Before this fix, ``finish_sync`` used a constant 60s ``failure_backoff_s``
+regardless of how many consecutive failures preceded. When an upstream
+peer (e.g. the seed onion) returned HTTP 429 "Too Many Requests", the
+sync worker would:
+
+  1. Receive 429
+  2. Stringify the status into a generic ``ValueError``
+  3. Call ``finish_sync(error=str(exc))`` -- losing the status code
+  4. Schedule next attempt for ``now + 60s``
+  5. Retry. Upstream's rate-limit bucket is still full. 429 again. Loop.
+
+Net effect: a node with one transient 429 would hammer the upstream
+every 60s forever, keeping the bucket full and never recovering. This
+is what kept the user's Infonet node from reaching the seed peer.
+
+What the fix does
+-----------------
+* New typed exception ``PeerSyncRateLimited`` carries the parsed
+  ``Retry-After`` value out of the HTTP layer.
+* ``_sync_from_peer`` returns ``(ok, error, forked, retry_after_s)``
+  instead of the old 3-tuple.
+* ``finish_sync`` honors ``retry_after_s`` AND applies exponential
+  backoff: ``delay = max(retry_after_s, base * 2^failures, cap=1800)``.
+* ``parse_retry_after_header`` handles both RFC 7231 forms (delay
+  seconds, and HTTP-date).
+
+These tests pin every part of the new contract.

+"""Per-(sender, recipient) anti-spam cap on the DM relay.
+
+The user-stated rule: a single sender can have at most N UNACKED messages
+parked in a single recipient's mailbox at any one time (N=2 by default).
+Once the recipient pulls a message, the sender's quota for that pair
+frees up.
+
+Network rule, not local rule
+-----------------------------
+The cap is enforced TWICE:
+
+1. ``DMRelay.deposit(...)`` -- local check on the sender's own node.
+   Refuses to spool the (N+1)th message before it can be replicated.
+
+2. ``DMRelay.accept_replica(...)`` -- replication-acceptance check on
+   every receiving peer. Refuses to accept an inbound replica that
+   would put the local mailbox over the cap, even if the originating
+   peer claims it had cap room.
+
+The double enforcement matters because cap (1) is client-side -- a
+hostile relay could patch it out and continue to spool extras locally.
+Cap (2) means those extras can't propagate: every honest peer rejects
+them on the way in. A recipient who polls from honest peers therefore
+never sees more than N pending from any one sender, regardless of how
+many spam attempts the sender's own relay accepted.
+
+These tests pin both halves of the rule.

+"""POST /api/mesh/dm/replicate-envelope — receiving side of cross-node DM
+mailbox replication.
+
+This is the endpoint that peer relays call when they want to hand off an

+find their messages). It re-enforces the per-(sender, recipient) anti-spam
+cap so hostile sender relays can't widen the cap by skipping the local
+check on their own deposit path.
+
+The endpoint:
+
+  * authenticates the caller via the existing per-peer HMAC pattern
+    (same one /api/mesh/infonet/peer-push and /api/mesh/gate/peer-push
+    use, introduced in #256 — ``X-Peer-Url`` + ``X-Peer-HMAC`` headers
+    keyed off ``resolve_peer_key_for_url``)
+  * rejects bodies > 64 KB (DM envelope size is bounded by
+    ``MESH_DM_MAX_MSG_BYTES`` — 64KB ceiling has generous headroom)
+  * rejects requests without a valid peer HMAC with 403
+  * passes the envelope to ``DMRelay.accept_replica`` which enforces
+    the cap
+
+This file pins the endpoint contract. The cap enforcement itself is
+tested in ``test_dm_relay_per_sender_cap.py`` against the relay's

+"""Per-flight source attribution.
+
+Background
+----------
+Pre-fix, adsb.lol records (the primary source for most flights) carried
+no source marker. OpenSky records got ``is_opensky: True`` and
+supplementals got ``supplemental_source``, so any UI that wanted to show
+which provider a flight came from saw OpenSky/airplanes.live records as
+explicitly tagged and adsb.lol records as "unlabeled" — making it look
+like adsb.lol wasn't even being used.
+
+This caused user confusion ("only military planes have adsb.lol
+telemetry") that was diagnostic noise, not a real bug. The actual fix:
+stamp ``source`` at every fetch site so the downstream consumer can
+attribute the provider with no guesswork.
+
+These tests pin:
+
+  * adsb.lol regional records get ``source: "adsb.lol"`` at fetch time
+    (synthesized via the published flight dict).
+  * OpenSky records get ``source: "OpenSky"`` (alongside the existing
+    ``is_opensky: True`` for backwards compat).
+  * Supplementals (airplanes.live, adsb.fi) flow through with their
+    ``supplemental_source`` honored.
+  * The military fetcher tags ``source`` on military_flights and uavs.
+  * The published flight dict carries ``source`` so downstream code
+    can render attribution.

+"""Issue #239 (tg12): backend registers duplicate API routes in both
+``main.py`` and router modules, so request behavior depends on the
+order ``FastAPI`` happened to register them.
+
+This test is the **CI guard** that locks in the invariant going forward.
+It does NOT delete any existing duplicates — those are tolerated via an
+explicit baseline file. What it DOES block is *new* duplicates appearing
+later, which is what the audit was actually asking for: a way to stop
+the drift before it gets worse.
+
+Findings (empirically verified, see PR #286 description):
+
+- ``main.app`` calls ``include_router(...)`` for every router at module
+  import time around line 3316.
+- Every ``@app.get/post/put/...`` decorator inside ``main.py`` runs
+  *after* those include_router calls, so the router handler is the one
+  that actually serves requests. The duplicates in ``main.py`` are
+  dead code at the route-resolution layer.
+- Behavior today is deterministic (router wins), but if someone later
+  adds a NEW route only in ``main.py``, or edits one copy of an
+  existing pair without the other, drift starts.
+
+How this test works:
+
+- Walks ``main.app.routes`` and records every ``(method, path)`` that
+  appears more than once, along with which modules registered each
+  copy.
+- Compares that set against the baseline in
+  ``backend/tests/data/duplicate_routes_baseline.json``.
+- **Fails** if any duplicate appears that is NOT in the baseline
+  (or if the registering modules for an existing duplicate change).
+- **Stays green** when duplicates are *removed* by genuinely deduping
+  the code. (The baseline is a ceiling, not a floor.)
+
+To extend in the future:
+
+- If you actually dedupe a route, leave the baseline alone — the test
+  still passes. Subsequent regenerations of the baseline (``python -m
+  scripts.regen_duplicate_routes_baseline`` or the snippet in this
+  test's docstring) will shrink it.
+- If you legitimately need a new duplicate (you probably do not), add
+  it to the baseline AND explain why in the PR description so reviewers
+  can push back.

+"""Issue #302 (tg12): OpenClaw connect-info HMAC secret disclosure.
+
+Before this change, ``GET /api/ai/connect-info?reveal=true`` returned the
+full HMAC secret in the response body on every modal open AND the same
+GET endpoint auto-bootstrapped (generated + persisted) the secret on a
+mere read. Even gated to ``require_local_operator``, that put the full
+secret into:
+
+  * browser visit history
+  * dev-tools network panel
+  * browser disk cache
+  * HAR exports
+  * screen captures / shoulder-surfing
+
+Every single time the OpenClaw Connect modal opened.
+
+After this change:
+
+  GET  /api/ai/connect-info            — always returns the MASKED
+                                          fingerprint. No ?reveal param.
+                                          No side effects (auto-bootstrap
+                                          gone).
+  POST /api/ai/connect-info/bootstrap  — mints+persists the secret if
+                                          missing. Idempotent. Never
+                                          returns the full secret.
+  POST /api/ai/connect-info/reveal     — returns the full secret with
+                                          strict Cache-Control: no-store
+                                          headers. POST so the body
+                                          doesn't land in URL history.
+  POST /api/ai/connect-info/regenerate — keeps the one-time-disclosure
+                                          for the new secret (regen IS a
+                                          deliberate destructive action).
+                                          Same no-store headers added.

+"""Round 7a: per-install operator handle threads through every outbound
+third-party API call.
+
+Background: before this change every Shadowbroker install identified
+itself to Wikipedia, Wikidata, Nominatim, GDELT, OpenMHz, Broadcastify,
+weather.gov, NUFORC, etc. with a single project-wide ``Shadowbroker``
+User-Agent. From the upstream's perspective, every install in the world
+looked like one giant scraper. If one install misbehaved, the upstream's
+only recourse was to block ``Shadowbroker`` as a whole, taking out every
+other install.
+
+Fix: each install gets a stable pseudonymous handle (auto-generated like
+``shadow-7f3a92`` or operator-overridden via ``OPERATOR_HANDLE``) that
+gets embedded in the User-Agent for every outbound call. Upstreams can
+now rate-limit / contact the specific operator instead of the project.
+
+These tests pin:
+
+  1. The handle is auto-generated on first call if no override exists.
+  2. The handle survives process restart (persisted to disk).
+  3. ``OPERATOR_HANDLE`` env var override wins over the auto-gen handle.
+  4. The handle is sanitized (whitespace, special chars, length).
+  5. Every previously-MONSTER-UA call site now sends the per-operator UA.

+"""Issue #298 (tg12): Sentinel credentials must live server-side.
+
+Before the fix, ``frontend/src/components/SettingsPanel.tsx`` stored
+``client_id`` and ``client_secret`` in ``localStorage`` /
+``sessionStorage`` via the privacy storage helper, and the proxy routes
+in ``backend/routers/tools.py`` REQUIRED those values to come in the
+request body. Any same-origin script (XSS, malicious extension,
+dev-tools HAR export) had read access to real third-party Sentinel
+credentials.
+
+After the fix:
+
+  * ``SENTINEL_CLIENT_ID`` and ``SENTINEL_CLIENT_SECRET`` are entries
+    in the ``api_settings.API_REGISTRY`` and are persisted via the
+    existing ``/api/settings/api-keys`` flow (admin-gated, .env-backed,
+    never returned to the browser).
+  * The proxy routes prefer request-body values for back-compat but
+    fall back to ``os.environ.get("SENTINEL_CLIENT_ID")`` /
+    ``os.environ.get("SENTINEL_CLIENT_SECRET")`` when the body omits
+    them. The dashboard's ``sentinelHub.ts`` no longer sends credentials
+    in the body — every request now hits the env path.
+  * When neither source has a value, the route returns a 400 with a
+    pointer to the API Keys panel rather than a curt "client_id and
+    client_secret required" message.
+
+These tests cover the resolution order and the registry surface.

+``Depends(require_local_operator)``:
+
+  * ``POST /api/sentinel/token``  — Copernicus CDSE OAuth relay for

+    relay for any Copernicus account.
+  * ``GET  /api/sentinel2/search`` — Planetary Computer STAC search with

+The fix adds ``dependencies=[Depends(require_local_operator)]`` to each.

- * This does NOT change end-user UX:
- *
- *   - WikiImage still shows the same thumbnails.
- *   - NewsFeed still shows aircraft thumbnails.
- *   - useRegionDossier still returns the same place summary + leader.
- *
- * What changes:
- *
- *   - Wikimedia can identify our traffic from any other anonymous
- *     browser visitor pool.
- *   - Provider-policy fixes happen here once, not in three places.
+ * UX impact: zero. Same thumbnails, same summaries, same load behavior.
+ * The only observable change is the value of the outgoing
+ * `Api-User-Agent` header.
