The category clamp fixed WHICH content the first store render draws, but
the tab bar was still missing on first entry (operator-observed: first
open = bronze packs with no tab bar; re-entry = same packs WITH
Bronze/Silver/Gold tabs).
Root cause: the store screen dispatcher 0x18007d880 publishes the tab bar
on a DIFFERENT event than it renders. Event 0x278a -> FUN_18007df60
resolves the six hardcoded tab tokens against the loaded purchase groups
and publishes *_CATEGORY_ID; event 0x753f -> FUN_18007dab0 renders. On
first entry the publish runs before /store/purchasegroup has landed, so
all six tokens resolve -1, every panel hides, and no tab bar is drawn;
re-entry only works because the groups are cached by then.
Re-run the native publish once per screen from the render detour, where
the groups are provably present (the ordinal-1 lookup already proves it),
reproducing the working re-entry order (publish, then render). Safe: it
is the same call the dispatcher makes with the same single argument, it
self-gates on screen+0x2cc == 0x418 (a mismatch is a native no-op, not a
fault), it is fingerprinted before the first call, and it runs at most
once per screen instance. Also logs the gate state so a no-op publish is
diagnosable. fmt/clippy -D warnings clean, 29 hook tests pass.
The FUT store flashes a Browse-Packs overview on first open: the store
screen ctor leaves screen+0x290 (CATEGORY_ID) at 0, and the resolver
FUN_1800147f0 treats 0 as list-all, so the first render draws the group
overview before the movie posts a tab ordinal.
Detour the store render FUN_18007dab0 (RVA 0x7dab0): when the incoming
category is 0, substitute the first present group ordinal (1) so the
first frame lands on a real tab. Provably crash-safe: it writes 1 only
after FUN_180014420(_, 1) (the resolver's own ordinal->group lookup,
whose first arg is dead) returns non-NULL, which is exactly the
resolver's non-crash precondition; the positive-invalid NULL deref at
0x14882 is thus unreachable. No group yet -> category left 0 -> Browse,
still safe.
Promoted like the SBC dispatch: build-armed (CLAMP_PROMOTED), no env.
Signature-gated on both the detoured render and the called lookup,
image-validated, installed under thread suspension, fail-closed. Only
the overview flash is addressed; the empty-My-Packs entry dialog is
movie-side (packed .apt) and out of CardsDLL reach (see Vault
Store Resolver Guard 2026-08-19). fmt/clippy -D warnings clean both
feature sets, 26 hook tests pass, x86_64-pc-windows-gnu release builds.
