Close the last D-234 piece — terrain water-direction extraction wired through
to founding orientation and the quarter waterfront rule:
- Layer 1: TerrainAnalysis::water_bearing — 8-octant integer bearing toward the
nearest water from the water_dist gradient (D-010, no atan2). Stored on
GeographicAttractor.water_bearing (360 = none).
- #956 founding orientation: coastal/river settlements now get a real
water-facing bearing (the anchoring attractor's), replacing the 0 stub.
- #957 waterfront rule (D-234b): the water-facing quarter edge (from the
settlement's Coastal founding orientation) drops its block setback to 0 so
buildings present flush to the quay (dock-orthogonal). Typed Edge + coastal_edge
+ per-block gating.
Golden + atlas_response fixture rebaked (additive water_bearing field only).
8 new tests. All integer-deterministic (D-010).
Pending: the waterfront rule reads context.founding_orientation, which
city_context_reader still stubs to Cardinal — real per-settlement orientation
reaches quarter generation once the Layer-3 placement -> Layer-4 GenerateSkeleton
dispatch is wired (the remaining cross-layer integration).

DrainageBasin gained a territorial_status field, so the Layer-1 golden and the
atlas_response msgpack fixture pick it up. Both changes are additive/
representational — basin/attractor/river selection is unchanged.
- cascade_golden.rs: pass None dominant_faction; golden rebaked (only
"territorial_status": "FrontierUnclaimed" added per basin).
- gen_fixtures.rs: set the new field in the atlas_response generator; fixture
regenerated.

all_fixtures_deserialize panicked with "unknown fixture naming
convention: atlas_response_ready" — the test reads every .msgpack in
client/tests/fixtures/msgpack but had no branch for the atlas_response
prefix (the AtlasLayerResponse fixtures gen_fixtures emits, #969). A
pre-existing gap (present on main; the suite isn't gated by the pre-push
hook, which runs cargo-deny/ruff/JSON/stamp, not cargo test).
Add an atlas_response branch deserializing AtlasLayerResponse, and
regenerate atlas_response_ready.msgpack so its bytes match the now-integer
GeographicAttractor types (#955).

Two Layer-1 generation fixes surfaced by the per-layer atlas viewer:
- Layer1Output now carries grid_w/grid_h (the downsampled working-grid the
positions live in). The client maps overlays from these, so the scale is
correct for any source heightmap resolution rather than assuming the texture
size — fixes overlays projecting at half scale into a corner.
- Drainage basin boundaries are traced as ordered, non-self-crossing contours
via Moore-neighbour tracing instead of an angle-from-centroid sort. The sort
produced star-shaped, self-crossing polygons for concave basins that rendered
as straight chords across the map.
Golden (cascade_layer1.json) and the cross-language atlas_response_ready
fixture regenerated. 100 atlas lib tests + the new tracer test pass.

Client half of the layer-stream protocol (codec only; transport wiring next).
- protocol.gd: encode_atlas_layer_request (bare {body_id, up_to} map so the
server demux routes it to the proxy, not the PlayerInput array) and
decode_atlas_layer_response (-> {body_id, status, error, layer1}; returns null
for non-atlas frames, e.g. a snapshot, so receive_bytes can disambiguate).
- gen_fixtures.rs: cross-language fixtures (atlas_response_ready/pending/
not_found) from real rmp_serde output, matching the test_protocol.gd pattern.
- test_protocol.gd: 5 tests decode the fixtures + verify a snapshot is not
mistaken for a response + the request encodes to the right shape. 68/68 pass.
