Hand-test finding K27: Architecture had scattered ways back with different
meanings (the Overview trail, a "Back" in System structure that walked the
focus, a "Back" in Behavior that walked the starts) and no way back from
"Show these N routes". Nothing went forward.
Architecture now keeps one place (subtab; opened area or file and Plan or
3D; route perspective and filter; System structure focus and expanded
groups; Behavior start, destination and where followed calls began) and
records it in the bounded model Galaxy uses (graph/navigation-history.ts),
with the same rules: at most 25 steps, consecutive duplicates merge, a new
navigation after Back drops the forward branch, no pushState, a Recent list
of 8 places, Alt+Left and Alt+Right only in the active workspace and not
while typing or while another surface takes the keys, a fresh history per
project.
Back, Forward and Recent sit beside the subtabs; their tooltips name the
target ("Back to Overview · django"). The old "Back" buttons in System
structure and Behavior stay in place and take the same step. "Whole system"
and the Overview trail stay as ordinary steps.
Architecture adds three refinements: typing in the route filter becomes one
step once it pauses; a choice the page makes itself (the suggested Behavior
start, a reset after reindexing) replaces the current step
(replaceNavigation), so Back never bounces on it; and the current step
keeps the newest details of its place (refreshNavigation), so a step whose
suggested start was rejected for a stale snapshot is still named after the
start the journey shows.
The views read their part of the place from the workspace and report
changes back; rendered on their own, as in their unit tests, they keep it
as their own state and offer no Back. A new tab row class avoids the
existing atlas-arch-bar meter. The concept doc now covers both workspaces.
