Every screen-targeted intent now routes through one
_require_current_screen() check and returns the structured error shape
instead of silently mutating an off-screen viewer (hoshe's finding:
scroll_rung from the reach screen fired real IPC and reported ok). The
reference driver's fixed 4-frame settle becomes is_pending()-aware with
a 600-frame bound, the keep-waiting decision extracted as a pure
testable function — restoring the proven eyeball-driver discipline. The
terrain_reference guard moves into AtlasApp._on_body_selected(), the
shared tail for double-click, Enter, AND the intent path — closing a
pre-existing click/Enter divergence hoshe caught this PR formalizing;
the intent layer pre-checks via the new SystemScreen.find_body() and
reports structured errors for unknown ids and terrain-less bodies.
after_test() resets AtlasAgentBridge.current_app (tyre's freed-pending
footgun). Suites 58/58 + 14/14; full suite 3,638.

D-226 layer 4, rebuilt against the post-D-255 stepped Atlas after the
Phase-1 reconciliation (the original intent list targeted the retired
continuous-zoom viewer). Eleven intents, each backed by the exact
production handler a click calls — select/open for systems and bodies
(extracted shared by-id tails so click and intent paths are one code
path), scroll_rung, reset_view, back, open/close_atlas, set_overlay —
plus two new first-class capabilities: jump_to_center (the fixed-center
revisit pattern proven by five eyeball drivers, via a new
StepCanvasViewer.jump_to seam that reuses _scroll_rung's exact request
tail — same extent cap, same cache keys) and get_current_canvas_summary
(allocation-light reads off the raw wire dict, courses-by-class,
draw-matched settlement dedup — no PNG decode). Contract shape: dumb
AtlasAgentBridge autoload holding the app handle (untyped per the
parse-order rule), all logic in the static AtlasAgentInterface class.
observe() is side-effect-free: current state + a generic Control-walk
affordance tree. In-process consumers only this ticket (documented);
the committed reference driver (atlas_agent_driver.gd, InputSwallower +
settle-until-ready from the T-1157 inventory) replaces the scratch
eyeball drivers as the sanctioned headless-drive pattern.
select_city/open_regional dropped with recorded rationale (no
settlement hit-test affordance exists post-D-255) — diff on the ticket.
33 new tests across three suites.
