docs/game/navigation.md is a second document unreachable from main, and
authored/flow.json is its executable form -- nothing in the port fails when a
label drifts from it. Three more checks in contract-check, anchored on the walk's
own text: the five main-menu labels in order, EXTRAS' three items, the cursor
wrap. Ten checks now, ten known negatives, all passing.
The manual audit behind them found nothing else: initial focus is already
kind:authored citing Q5's instability, left_right is an explicit no-op,
auto_repeat is measured, unexported destinations are marked blocked with reasons.
Refutation target: the walk's claim that the ring is the ONLY thing moving on the
settled menu. Cannot be tested against the game from here, but can be tested
against my renderer, which is the direction that matters. Five renders across a
full ring cycle: 1428 of 921600 pixels vary, 0.155 %, one 46x44 cluster beside
the focused item. The port animates one ring, not five -- worth checking, since
all five ptbtn01f..05f declare the same 120-unit cycle and a renderer running all
of them would look identical until you diffed frames.
Then I nearly filed a serious P5 defect against myself: sweeping --leaf-time with
the ring pinned moves 10.4 % of the frame, full-screen. It is not a defect. That
pin addresses the build-in -- ptloop01 runs t=0..600, ptloop02 t=0..720 -- and at
settle both park off-screen at x=1521 and x=-839, with loop_leaf_on_screens
scoped to the title alone. The general form: a pin that can address states the
screen never occupies will manufacture defects on demand, which inverts what the
three pins are for.
The +0x08 ask came back answered and is not consumable. ui_layout::loop_length_units
is public at b5df02a and byte-for-byte what screen.rs holds, so the deletion is
one line -- but Cargo.toml pins a tag, no tag carries that commit, and swapping a
deliberate pin for a bare rev on an unmerged branch is not a move to make alone.
Asked for a tag; keeping the guarded local read.
